傳統的接觸式溫度計，例如水銀式或電子式溫度計已不能滿足使用者的需求，故需有進一步能追求精確、快速、容易量測、容易判讀、不具傷害和更符合人性化的溫度量測方法及裝置。目前利用量測紅外線輻射熱的非接觸式溫度量測裝置，例如包含有耳溫槍或額溫槍，其正具有上述優點，因此已逐漸成為主流的體溫量測裝置。Traditional contact thermometers, such as mercury or electronic thermometers, can no longer meet the needs of users, so there is a need for further temperature measurement methods that are accurate, fast, easy to measure, easy to interpret, non-invasive and more user-friendly.

At present, a non-contact temperature measuring device that measures infrared radiant heat, for example, includes an ear thermometer or a front temperature gun, which has the above advantages, and thus has gradually become a mainstream body temperature measuring device.

值得一提的是，額溫槍在量測溫度的過程中，會受到額溫槍與受測者之間的距離影響。距離愈長，量測得到的溫度會愈低；距離愈短，量測得到的溫度會愈高。使用者在使用額溫槍的過程中，受測者與額溫槍之間的距離，會隨著不同使用者的操作習慣而有所不同。如此一來額溫槍的精準度會下降，甚至會讓使用者誤判體溫。It is worth mentioning that the temperature gun is affected by the distance between the temperature gun and the subject during the measurement of temperature. The longer the distance, the lower the measured temperature will be; the shorter the distance, the higher the measured temperature will be. During the use of the temperature gun, the distance between the subject and the temperature gun will vary with the operating habits of different users. As a result, the accuracy of the temperature gun will decrease, and even the user may misjudge the body temperature.

圖1是依照本發明的第一實施例所繪示的一種溫度感測裝置的方塊圖。請先參照圖1，在本實施例中，溫度感測裝置10以額溫槍為例進行說明，但本發明並不限於此。溫度感測裝置10包括測溫模組30、測距模組40與處理模組20。測溫模組30可透過一距離偵測活體50的一體溫值。在本實施例中，活體50例如是人體的額頭，但本發明並不以此為限。測距模組40可用以偵測溫度感測裝置10與活體50之間的一距離值。處理模組20耦接測溫模組30與測距模組40，可依據距離值與體溫值產生一輸出體溫值。以下先針對測距模組40作更詳細的描述。1 is a block diagram of a temperature sensing device in accordance with a first embodiment of the present invention.

The processing module 20 is coupled to the temperature measuring module 30 and the distance measuring module 40, and can generate an output body temperature value according to the distance value and the body temperature value. The following is a more detailed description of the ranging module 40.

圖2是依照圖1所繪示的一種詳細方塊圖。請參照圖2，在本實施例中，測距模組40以光感測技術為例進行說明，但本發明並不以此為限。測距模組40包括發光單元401與光接收單元402。發光單元401耦接處理模組20，可依據處理模組20產生的控制訊號對活體50發射一預設能量的一第一光。光接收單元402耦接處理模組20，可接收活體50反射的第二光的能量，並據以產生電子訊號。一般來說，光接收單元402所接受到的第二光的能量愈強，代表溫度感測裝置10與活體50之間的距離值愈近；反之，光接收單元402所接受到的第二光的能量愈弱，代表溫度感測裝置10與活體50之間的距離值愈遠。因此，處理模 組20可依據光接收單元402所提供的電子訊號藉以估測溫度感測裝置10與活體50之間的一距離值。2 is a detailed block diagram of FIG. Referring to FIG. 2 , in the embodiment, the distance measuring module 40 is described by taking a light sensing technology as an example, but the invention is not limited thereto. The ranging module 40 includes a light emitting unit 401 and a light receiving unit 402. The illuminating unit 401 is coupled to the processing module 20, and can emit a first light of a preset energy to the living body 50 according to the control signal generated by the processing module 20. The light receiving unit 402 is coupled to the processing module 20 and can receive the energy of the second light reflected by the living body 50 to generate an electronic signal. In general, the stronger the energy of the second light received by the light receiving unit 402, the closer the distance between the temperature sensing device 10 and the living body 50 is. The second light received by the light receiving unit 402 is reversed. The weaker the energy, the further the distance between the temperature sensing device 10 and the living body 50. Therefore, processing the mode The group 20 can estimate a distance value between the temperature sensing device 10 and the living body 50 according to the electronic signal provided by the light receiving unit 402.

另外，測距模組40還可包括訊號處理單元403。訊號處理單元403耦接於光接收單元402與處理單元20之間，用以對電子訊號進行一訊號處理。更具體地說，在本實施例中，光接收單元402例如是可將第二光的能量轉為類比式電子訊號。為方便處理模組20進行處理，可透過訊號處理單元403對電子訊號進行前處理，例如將類比式電子訊號放大、將類比訊號轉為數位訊號及/或對電子訊號進行濾波處理，藉以過濾雜訊。訊號處理模組403再將處理過後的電子訊號傳送給處理模組20。In addition, the ranging module 40 can further include a signal processing unit 403. The signal processing unit 403 is coupled between the light receiving unit 402 and the processing unit 20 for performing a signal processing on the electronic signal. More specifically, in the present embodiment, the light receiving unit 402 can, for example, convert the energy of the second light into an analog electronic signal. To facilitate processing by the processing module 20, the electronic signal can be pre-processed by the signal processing unit 403, for example, to amplify the analog electronic signal, convert the analog signal into a digital signal, and/or filter the electronic signal, thereby filtering the impurities.

處理模組20接收到電子訊號後，可依據電子訊號所反映出的第二光的能量強弱，藉以估測溫度感測裝置10與活體50之間的距離值。處理模組20可再依據此距離值藉以校正測溫模組30對活體50所偵測得到的溫度值。以下配合溫度感測方法的流程圖作更進一步地說明。After receiving the electronic signal, the processing module 20 can estimate the distance between the temperature sensing device 10 and the living body 50 according to the energy intensity of the second light reflected by the electronic signal. The processing module 20 can further correct the temperature value detected by the temperature detecting module 30 on the living body 50 according to the distance value. The following is further explained in conjunction with the flow chart of the temperature sensing method.

圖3是依照本發明的第一實施例所繪示的一種溫度感測方法的流程圖。請合併參照圖2與圖3，在本實施例中假設測溫模組30的較佳測溫距離，例如為12cm。測溫距離愈接近12cm，其測得的溫度值的誤差會愈小；反之測溫距離與12cm差異愈大，其測得的溫度值的誤差會愈大。從另一角度來看，當測溫距離大於12cm，其測得的溫度值會偏低；當測溫距離小於12cm，其測得的溫度值會偏高。FIG. 3 is a flow chart of a temperature sensing method according to a first embodiment of the present invention. Referring to FIG. 2 and FIG. 3 together, in the present embodiment, the preferred temperature measurement distance of the temperature measurement module 30 is assumed to be, for example, 12 cm. The closer the temperature measurement distance is to 12cm, the smaller the error of the measured temperature value will be; the greater the difference between the temperature measurement distance and 12cm, the greater the error of the measured temperature value. From another point of view, when the temperature measurement distance is greater than 12cm, the measured temperature value will be low; when the temperature measurement distance is less than 12cm, the measured temperature value will be higher.

承上述，可由步驟S301，測溫模組30偵測活體50 的體溫值，例如38.10℃。另一方面，可由步驟S302，測距模組40偵測溫度感測裝置10與活體50之間的距離值，例如6cm。接著，可由步驟S303，處理模組20依據距離值與體溫值產生一輸出體溫值。更具體地說，處理模組20可依據距離值6cm對體溫值38.10℃進行校正。由於溫度感測裝置10與活體50之間的距離值小於測溫模組30的較佳測溫距離為12cm，因此測溫模組30所量測到的體溫值38.10℃，會比活體50的實際溫度更高。因此，處理模組20可依據上述距離值與體溫值，進行一溫度校正演算法，藉以獲得更準確的輸出體溫值，例如獲得輸出體溫值為37.60℃。如此一來，可降低量測距離對溫度感測裝置10進行溫度量測的干擾，藉以提昇溫度感測裝置10的準確度。也可改善使用者誤判體溫的情況。需一提的是，本領域技術者應當知道溫度校正演算法的相當多樣，本領域技術者可依其需求自行選擇適當的溫度校正演算法。In the above, the temperature detecting module 30 can detect the living body 50 in step S301. The body temperature value, for example, 38.10 ° C. On the other hand, the distance measuring module 40 can detect the distance value between the temperature sensing device 10 and the living body 50, for example, 6 cm, in step S302. Then, in step S303, the processing module 20 generates an output body temperature value according to the distance value and the body temperature value. More specifically, the processing module 20 can correct the body temperature value of 38.10 ° C according to the distance value of 6 cm. Since the distance between the temperature sensing device 10 and the living body 50 is less than the preferred temperature measurement distance of the temperature measuring module 30 is 12 cm, the body temperature value measured by the temperature measuring module 30 is 38.10 ° C, which is better than that of the living body 50. The actual temperature is higher. Therefore, the processing module 20 can perform a temperature correction algorithm according to the distance value and the body temperature value to obtain a more accurate output body temperature value, for example, obtaining an output body temperature value of 37.60 ° C. In this way, the interference of the measurement distance to the temperature measurement of the temperature sensing device 10 can be reduced, thereby improving the accuracy of the temperature sensing device 10. It can also improve the user's misjudgment of body temperature. It should be noted that those skilled in the art should be aware that the temperature correction algorithm is quite diverse, and those skilled in the art can select an appropriate temperature correction algorithm according to their needs.

在另一情況下，可由步驟S301，測溫模組30偵測活體50的體溫值，例如36.05℃。另一方面，可由步驟S302，測距模組40偵測溫度感測裝置10與活體50之間的距離值，例如18cm。接著，可由步驟S303，處理模組20依據距離值與體溫值產生一輸出體溫值。更具體地說，處理模組20可依據距離值18cm對體溫值36.05℃進行校正。由於溫度感測裝置10與活體50之間的距離值大於測溫模組30的較佳測溫距離為12cm，因此測溫模組30所量測到的體溫值36.05℃，會比活體50的實際溫度更低。因此，處 理模組20可依據上述距離值與體溫值，進行溫度校正演算法，藉以獲得更準確的輸出體溫值，例如獲得輸出體溫值為37.60℃。也就是說，溫度感測裝置10可依據量測距離的遠近進行相對應的溫度校正，使用者在不同距離下進行溫度量測都可以獲得較精準的溫度。In another case, the temperature measurement module 30 can detect the body temperature value of the living body 50, for example, 36.05 ° C, in step S301. On the other hand, the distance measuring module 40 can detect the distance value between the temperature sensing device 10 and the living body 50, for example, 18 cm, in step S302. Then, in step S303, the processing module 20 generates an output body temperature value according to the distance value and the body temperature value. More specifically, the processing module 20 can correct the body temperature value of 36.05 ° C according to the distance value of 18 cm. Since the distance between the temperature sensing device 10 and the living body 50 is greater than the preferred temperature measurement distance of the temperature measuring module 30 is 12 cm, the body temperature value measured by the temperature measuring module 30 is 36.05 ° C, which is higher than that of the living body 50. The actual temperature is lower. Therefore, at The module 20 can perform a temperature correction algorithm based on the above distance value and body temperature value to obtain a more accurate output body temperature value, for example, obtaining an output body temperature value of 37.60 ° C. That is to say, the temperature sensing device 10 can perform corresponding temperature correction according to the distance of the measuring distance, and the user can obtain a more accurate temperature by performing temperature measurement at different distances.

The difference is that the temperature sensing device 11 further includes a look-up table unit 60. The look-up table unit 60 is coupled to the processing module 20 and stores a plurality of tables, such as Tables 1 through 3 below.

在本實施例中，處理模組20可依據測距模組40所獲得的距離值選擇上述表的其一，例如距離值為16cm則選擇表三，在依據測溫模組30所量測到的體溫值並配合查表方式，就可以快速獲得輸出體溫值。例如測溫模組30量測到的體溫值為36.50℃，則可獲得輸出體溫值36.75℃。本領域技術者也可再配合使用內差法，在此不再贅述。本領域技術者應當知道上述表一至表三僅是一種選擇實施例，本領域技術者可依其需求調整各表中的數值。In this embodiment, the processing module 20 can select one of the tables according to the distance value obtained by the ranging module 40. For example, if the distance value is 16 cm, the third table is selected, and the measurement module 30 measures the temperature. The body temperature value and the look-up table method can quickly obtain the output body temperature value. For example, if the body temperature value measured by the temperature measuring module 30 is 36.50 ° C, the output body temperature value of 36.75 ° C can be obtained. Those skilled in the art can also use the internal difference method, and will not be described here. Those skilled in the art should know that the above Tables 1 to 3 are only one alternative embodiment, and those skilled in the art can adjust the values in the tables according to their needs.

在第一實施例的圖2中，測距模組40雖以發光單元 401與光接收單元402為例進行說明，但其僅是一種選擇實施例，在其他實施例中，也可用其他技術來獲得溫度感測裝置10與活體50之間的距離值。舉例來說，測距模組40也可以用超音波或影像分析...等技術來實施。以下先針對超音波技術實施測距功能作更具體地說明。In FIG. 2 of the first embodiment, the ranging module 40 is a light emitting unit. The 401 and the light receiving unit 402 are described as an example, but it is only an alternative embodiment. In other embodiments, other techniques may be used to obtain the distance value between the temperature sensing device 10 and the living body 50. For example, the ranging module 40 can also be implemented by techniques such as ultrasonic or image analysis. The following is a more detailed description of the implementation of the ranging function for ultrasonic technology.

在第三實施例中，測距模組包括超音波發射單元與超音波接收單元。超音波發射單元耦接處理模組，可依據處理模組產生的控制訊號對活體發射第一超音波訊號。超音波接收單元耦接處理模組，可依據活體反射的第二超音波訊號產生電子訊號。處理模組可依據電子訊號獲得上述距離值。一般來說，溫度感測裝置與活體之間的距離愈遠，接收到第二超音波訊號的時間會愈晚；反之，溫度感測裝置與活體之間的距離愈近，接收到第二超音波訊號的時間會愈快。如此一來，就可以獲得溫度感測裝置與活體之間的距離值。以下再針對影像分析技術實施測距功能作更具體地說明。In the third embodiment, the ranging module includes an ultrasonic transmitting unit and an ultrasonic receiving unit. The ultrasonic transmitting unit is coupled to the processing module, and can transmit the first ultrasonic signal to the living body according to the control signal generated by the processing module. The ultrasonic receiving unit is coupled to the processing module, and generates an electronic signal according to the second ultrasonic signal reflected by the living body. The processing module can obtain the above distance value according to the electronic signal. Generally speaking, the farther the distance between the temperature sensing device and the living body is, the later the time of receiving the second ultrasonic signal; on the contrary, the closer the distance between the temperature sensing device and the living body is, the second super is received. The time of the sound signal will be faster. In this way, the distance between the temperature sensing device and the living body can be obtained. The following is a more detailed description of the implementation of the ranging function for image analysis technology.

在第四實施例中，測距模組可包括至少二影像擷取單元。兩影像擷取單元之間相距一預設距離。上述影像擷取單元耦接處理模組，可依據處理模組產生的控制訊號拍攝活體並產生至少二影像。處理模組可依據上述兩張影像所造成的視差來獲得溫度感測裝置與活體之間的距離值。一般來說，溫度感測裝置與活體之間的距離愈遠，兩張影像之間的視差會愈小；反之，溫度感測裝置與活體之間的距離愈近，兩張影像之間的視差會愈大。如此一來，就可以 獲得溫度感測裝置與活體之間的距離值。In the fourth embodiment, the ranging module may include at least two image capturing units. The two image capturing units are separated by a predetermined distance. The image capturing unit is coupled to the processing module, and can capture the living body according to the control signal generated by the processing module and generate at least two images. The processing module can obtain the distance value between the temperature sensing device and the living body according to the parallax caused by the two images. In general, the farther the distance between the temperature sensing device and the living body is, the smaller the parallax between the two images will be. On the contrary, the closer the distance between the temperature sensing device and the living body, the parallax between the two images. The bigger it will be. In this way, you can A distance value between the temperature sensing device and the living body is obtained.

在第五實施例中，測距模組包括變焦單元與影像擷取單元。變焦單元耦接處理模組，受處理模組的控制調整焦距。影像擷取單元耦接處理模組，受處理模組的控制在上述焦距下進行拍攝，藉以產生一影像。處理模組可依據上述影像與焦距獲得距離值。本領域技術者應當知道，在適當焦距下，影像中的目標物會相當清晰，處理模組在依據上述焦距以及其他參數即可計算出溫度感測裝置與活體之間的距離。如此一來，亦可獲得溫度感測裝置與活體之間的距離。In the fifth embodiment, the ranging module includes a zoom unit and an image capturing unit. The zoom unit is coupled to the processing module and is controlled by the processing module to adjust the focal length. The image capturing unit is coupled to the processing module, and is controlled by the processing module to perform shooting at the focal length to generate an image. The processing module can obtain the distance value according to the above image and the focal length. Those skilled in the art should know that at an appropriate focal length, the target in the image will be quite clear, and the processing module can calculate the distance between the temperature sensing device and the living body based on the above focal length and other parameters. In this way, the distance between the temperature sensing device and the living body can also be obtained.

在第一實施例的圖2中，訊號處理單元403僅是一種選擇實施例利用。在其他實施例中，訊號處理單元403也可以選擇性地與其他模組進行整合，例如整合於光接收單元402或處理模組20。如此亦可達成相類似的功效。在另一實施例中，光接收單元402也可直接將第二光的能量直接轉成數位訊號，以方便後續訊號處理。In Fig. 2 of the first embodiment, the signal processing unit 403 is only utilized by an alternative embodiment. In other embodiments, the signal processing unit 403 can also be selectively integrated with other modules, for example, integrated into the light receiving unit 402 or the processing module 20. This can also achieve similar effects. In another embodiment, the light receiving unit 402 can directly convert the energy of the second light into a digital signal to facilitate subsequent signal processing.

在第一實施例的圖2中，雖用訊號處理單元403進行數位或類比的濾波處理，藉以降低雜訊，但其僅是一種選擇實施例。在其他實施例中，測距模組40也可包括濾波鏡片(未繪示)。濾波鏡片可配置在光接收單元402與活體50之間，用以過濾第二光之外的雜訊。如此亦可降低雜訊干擾。In Fig. 2 of the first embodiment, although the signal processing unit 403 performs digital or analog filtering processing to reduce noise, it is only an alternative embodiment. In other embodiments, the ranging module 40 can also include a filter lens (not shown). The filter lens can be disposed between the light receiving unit 402 and the living body 50 to filter noise other than the second light. This can also reduce noise interference.

在第一實施例，量測溫度雖以單次量測為例進行說明，但其僅是一種選擇實施例。在其他實施例中，也可配 合多次量測獲得更精準的體溫值。以下以二次量測為例進行說明，本領域技術者也可依其需求改成三次或四次以上的量測。In the first embodiment, the measurement temperature is described by taking a single measurement as an example, but it is only an alternative embodiment. In other embodiments, it can also be configured Combine multiple measurements to obtain a more accurate body temperature value. Hereinafter, the second measurement is taken as an example for description, and those skilled in the art can also change the measurement to three or more times according to the requirements.

例如，圖5是依照本發明的第六實施例所繪示的一種溫度感測方法的流程圖。請合併參照圖1與圖5，首先可由步驟S501，測距模組40偵測溫度感測裝置10與活體50之間的第一距離值，例如6cm。另外，再由步驟S502，測溫模組30在第一距離值偵測活體50的一第一體溫值，例如38.30℃。如此就完成一次量測，接著可再由步驟S503、S504進行第二次量測。For example, FIG. 5 is a flow chart of a temperature sensing method according to a sixth embodiment of the present invention. Referring to FIG. 1 and FIG. 5 together, first, in step S501, the distance measuring module 40 detects a first distance value between the temperature sensing device 10 and the living body 50, for example, 6 cm. In addition, in step S502, the temperature measurement module 30 detects a first body temperature value of the living body 50 at the first distance value, for example, 38.30 ° C. Thus, a measurement is completed, and then a second measurement can be performed by steps S503 and S504.

此外，由步驟S503進行第二次量測，測溫模組30偵測溫度感測裝置10與活體50之間的第二距離值，例如7cm。再者，由步驟S504，測溫模組30在第二距離值偵測活體50的第二體溫值，例如38.20℃。如此即完成第二次量測。In addition, the second measurement is performed by step S503, and the temperature measurement module 30 detects a second distance value between the temperature sensing device 10 and the living body 50, for example, 7 cm. Furthermore, in step S504, the temperature measurement module 30 detects the second body temperature value of the living body 50 at the second distance value, for example, 38.20 °C. This completes the second measurement.

接著，可由步驟S505，處理模組20依據第一體溫值、第一距離值、第二體溫值與第二距離值產生一輸出體溫值。輸出體溫值的產生方式有很多種，在此舉一例子說明，但本發明並不以此為限。舉例來說，處理模組20可先依據第一距離值校正第一體溫值，以獲得一校正後的第一體溫值，例如是37.90℃。處理模組20可再依據第二距離值校正第二體溫值，以獲得一校正後的第二體溫值，例如是37.88℃。然後在依據校正後的第一體溫值與第二體溫值獲得輸出體溫值，例如取平均數，獲得輸出體溫值37.89℃。 如此一來可透過多次量測獲得更可靠或準確的輸出體溫值。Then, in step S505, the processing module 20 generates an output body temperature value according to the first body temperature value, the first distance value, the second body temperature value, and the second distance value. There are many ways to generate the output body temperature value, which is illustrated by way of example, but the invention is not limited thereto. For example, the processing module 20 may first correct the first body temperature value according to the first distance value to obtain a corrected first body temperature value, for example, 37.90 ° C. The processing module 20 can further correct the second body temperature value according to the second distance value to obtain a corrected second body temperature value, for example, 37.88 ° C. Then, the output body temperature value is obtained according to the corrected first body temperature value and the second body temperature value, for example, an average value is obtained, and an output body temperature value of 37.89 ° C is obtained. In this way, a more reliable or accurate output body temperature value can be obtained through multiple measurements.

在上述實施例中，處理模組20雖透過平均數獲得輸出體溫值，但在其他實施例中，也可配合使用中間數、最大數、最小數及或眾數等演算法。In the above embodiment, although the processing module 20 obtains the output body temperature value through the average number, in other embodiments, an algorithm such as an intermediate number, a maximum number, a minimum number, or a mode may be used.

在上述實施例中，溫度感測裝置雖透過測距功能來獲得更精準的輸出體溫值，但其僅是一種選擇實施例。在其他實施例中，本領域技術者也可依據測距功能的距離值藉以切換溫度感測裝置的操作模式。舉例來說，圖6是依照本發明的第七實施例所繪示的一種溫度感測方法的流程圖。請合併參照圖1與圖6，在本實施例中，處理模組20包括模式切換單元(未繪示)。模式切換單元可依據處理模組20所發出的電子訊號切換溫度感測裝置10的一操作模式。操作模式包括省電模式、正常模式、耳溫量測模式或額溫量測模式。可利用測距模組40所獲得的距離值(溫度感測裝置10與物體或活體50之間的距離)將溫度感測裝置10切入省電模式。In the above embodiment, the temperature sensing device obtains a more accurate output body temperature value through the ranging function, but it is only an alternative embodiment. In other embodiments, those skilled in the art can also switch the operation mode of the temperature sensing device according to the distance value of the ranging function. For example, FIG. 6 is a flowchart of a temperature sensing method according to a seventh embodiment of the present invention. Referring to FIG. 1 and FIG. 6 together, in the embodiment, the processing module 20 includes a mode switching unit (not shown). The mode switching unit can switch an operation mode of the temperature sensing device 10 according to the electronic signal sent by the processing module 20. The operation mode includes a power saving mode, a normal mode, an ear temperature measurement mode, or a fore temperature measurement mode. The temperature sensing device 10 can be cut into the power saving mode by using the distance value obtained by the distance measuring module 40 (the distance between the temperature sensing device 10 and the object or the living body 50).

一般來說，溫度感測裝置10在使用的過程其與活體50之間的距離通常會大於一距離，例如是5cm；溫度感測裝置10收納於盒子中，其與盒子內壁的距離會小於一距離，例如是5cm。據此，可先由步驟S601，測距模組40偵測溫度感測裝置10與活體50之間的距離值。再者，由步驟S602，依據距離值切換溫度感測裝置10的操作模式。更具體地說，當測距模組40所量測到的距離值小於一距 離，例如5cm時，處理模組20可判定溫度感測裝置10被收納於盒中，處理模組20可發出電子訊號控制模式切換單元將溫度感測裝置10切換至省電模式，其中省電模式例如是，縮短等待關機時間、降低背光亮度...等；反之，當測距模組40所量測到的距離值大於一距離，例如5cm時，處理模組20可判定溫度感測裝置10正在被使用者使用，處理模組20可發出電子訊號控制模式切換單元將溫度感測裝置10切換回正常模式。如此一來可達成省電效果。Generally, the distance between the temperature sensing device 10 and the living body 50 during the use of the temperature sensing device 10 is usually greater than a distance, for example, 5 cm; the temperature sensing device 10 is housed in the box, and the distance from the inner wall of the box is smaller than A distance, for example 5 cm. Accordingly, the distance measuring module 40 detects the distance value between the temperature sensing device 10 and the living body 50 by step S601. Furthermore, in step S602, the operation mode of the temperature sensing device 10 is switched in accordance with the distance value. More specifically, when the distance measured by the distance measuring module 40 is less than one distance When the distance is, for example, 5 cm, the processing module 20 can determine that the temperature sensing device 10 is stored in the box, and the processing module 20 can send an electronic signal control mode switching unit to switch the temperature sensing device 10 to the power saving mode, wherein the power saving mode is performed. For example, when the distance value measured by the distance measuring module 40 is greater than a distance, for example, 5 cm, the processing module 20 can determine the temperature sensing device. 10 is being used by the user, and the processing module 20 can issue an electronic signal control mode switching unit to switch the temperature sensing device 10 back to the normal mode. In this way, the power saving effect can be achieved.

在第七實施例中，處理模組20雖僅以測距模組40所獲得的距離值來作為切換操作模式的依據，但其僅是一種選擇實施例。在其他實施例中，處理模組20也可以配合其他參數來切換操作模式，例如也可以配合使用時間參數。In the seventh embodiment, the processing module 20 only uses the distance value obtained by the ranging module 40 as the basis for switching the operation mode, but it is only an alternative embodiment. In other embodiments, the processing module 20 can also switch the operation mode in conjunction with other parameters, for example, the time parameter can also be used.

請再參照圖1，在第八實施例中，處理模組20可接收計時器(未繪示)的時間參數與測距模組40所測得的距離值。一般來說，使用者在使用溫度感測裝置10的過程中，測距模組40所獲得的距離值會一直變動；反之，溫度感測裝置10收納於盒子中，測距模組40所獲得的距離值會固定於一值。據此，在一段時間內，例如10秒，測距模組40所提供的距離值的變動不超過2cm，處理模組20可將其判定為溫度感測裝置10收納於盒子中，處理模組20可發出電子訊號控制模式切換單元將溫度感測裝置10切換至省電模式；反之，在一段時間內，例如10秒，測距模組40所提供的距離值的變動超過2cm，處理模組20可將其判定使用者在正使用溫度感測裝置10，處理模組20可發 出電子訊號控制模式切換單元將溫度感測裝置10切換回正常模式。如此一來亦可達成省電效果。Referring to FIG. 1 again, in the eighth embodiment, the processing module 20 can receive the time parameter of a timer (not shown) and the distance value measured by the ranging module 40. Generally, in the process of using the temperature sensing device 10, the distance value obtained by the distance measuring module 40 is always changed; otherwise, the temperature sensing device 10 is stored in the box, and the distance measuring module 40 obtains The distance value will be fixed at a value. Accordingly, during a period of time, for example, 10 seconds, the distance value provided by the distance measuring module 40 does not exceed 2 cm, and the processing module 20 can determine that the temperature sensing device 10 is stored in the box, and the processing module 20 can send an electronic signal control mode switching unit to switch the temperature sensing device 10 to the power saving mode; conversely, within a period of time, for example, 10 seconds, the distance value provided by the distance measuring module 40 changes by more than 2 cm, and the processing module 20 can determine that the user is using the temperature sensing device 10, and the processing module 20 can send The electronic signal control mode switching unit switches the temperature sensing device 10 back to the normal mode. In this way, the power saving effect can also be achieved.

請再參照圖1，在第一實施例中，溫度感測裝置10雖以額溫槍為例進行說明，但其僅是一種選擇實施例。舉例來說，在第九實施例中，溫度感測裝置10也可以是額耳溫槍。在本實施例中，處理模組20的模式切換單元可依據測距模組40所獲得的距離值或切換額溫量測模式或耳溫量測模式。一般來說，使用者量測額溫時，溫度感測裝置10與活體50之間的距離不會小於一距離，例如5cm；反之，使用者進行耳溫量測時，探頭易碰觸到耳朵內壁，換言之，溫度感測裝置10與活體50之間的距離會小於一距離，例如5cm。Referring to FIG. 1 again, in the first embodiment, the temperature sensing device 10 is described by taking a front temperature gun as an example, but it is only an alternative embodiment. For example, in the ninth embodiment, the temperature sensing device 10 may also be an ear thermometer. In this embodiment, the mode switching unit of the processing module 20 can be based on the distance value obtained by the ranging module 40 or the switching amount temperature measurement mode or the ear temperature measurement mode. Generally, when the user measures the temperature, the distance between the temperature sensing device 10 and the living body 50 is not less than a distance, for example, 5 cm; otherwise, when the user performs the ear temperature measurement, the probe easily touches the ear. The inner wall, in other words, the distance between the temperature sensing device 10 and the living body 50 may be less than a distance, for example 5 cm.

據此，可先由步驟S601，測距模組40偵測溫度感測裝置10與活體50之間的距離值。再者，由步驟S602，依據距離值切換溫度感測裝置10的操作模式。當處理模組20接收到測距模組40所量測到的距離值小於5cm時，模式切換單元可將溫度感測裝置10切換至耳溫量測模式；反之，當處理模組20接收到測距模組40所量測到的距離值大於5cm時，模式切換單元可將溫度感測裝置10切換至額溫量測模式。在耳溫量測模式下，處理模組20會用耳溫校正演算法對測溫模組30量測到的體溫值作適當地校正，使校正後的體溫值更接近活體50的體溫；在額溫量測模式下，處理模組20會用額溫校正演算法對測溫模組30量測到的體溫值作適當地校正，使校正後的體溫值更接近 活體50的體溫。Accordingly, the distance measuring module 40 detects the distance value between the temperature sensing device 10 and the living body 50 by step S601. Furthermore, in step S602, the operation mode of the temperature sensing device 10 is switched in accordance with the distance value. When the processing module 20 receives the distance value measured by the ranging module 40 is less than 5 cm, the mode switching unit can switch the temperature sensing device 10 to the ear temperature measurement mode; otherwise, when the processing module 20 receives When the distance value measured by the distance measuring module 40 is greater than 5 cm, the mode switching unit can switch the temperature sensing device 10 to the fore temperature measurement mode. In the ear temperature measurement mode, the processing module 20 appropriately corrects the body temperature value measured by the temperature measurement module 30 by using the ear temperature correction algorithm, so that the corrected body temperature value is closer to the body temperature of the living body 50; In the pre-temperature measurement mode, the processing module 20 corrects the body temperature value measured by the temperature measuring module 30 by using the temperature correction algorithm, so that the corrected body temperature value is closer. The body temperature of the living body 50.

在上述實施例中，溫度感測裝置10雖以測距模組40所提供的距離值來作為切換操作模式的依據，但其僅是一種選擇實施例。在其他實施例中，溫度感測裝置10也可透過其他感測元件，例如光感測元件所提供的能量變化來作為切換操作模式的依據。舉例來說，在圖2中，處理模組20也可依據光接收單元402所提供的電子訊號作為切換操作模式的依據，其中電子訊號可反應活體50所反射的第二光的能量大小，且上述操作模式包括省電模式、正常模式、額溫量測模式或耳溫量測模式。如此一來，亦可達成與上述實施例相類似的功效。In the above embodiment, the temperature sensing device 10 uses the distance value provided by the ranging module 40 as the basis for switching the operation mode, but it is only an alternative embodiment. In other embodiments, the temperature sensing device 10 can also be used as a basis for switching the operation mode through other sensing elements, such as energy changes provided by the light sensing elements. For example, in FIG. 2, the processing module 20 can also be used as a basis for switching the operation mode according to the electronic signal provided by the light receiving unit 402, wherein the electronic signal can reflect the energy of the second light reflected by the living body 50, and The above operation modes include a power saving mode, a normal mode, a frontal temperature measurement mode, or an ear temperature measurement mode. In this way, effects similar to those of the above embodiment can also be achieved.

從另一角度來看，溫度感測裝置的測距功能也能用來產生觸發訊號。舉例來說，圖7是依照本發明的第十實施例所繪示的一種溫度感測方法的流程圖。請合併參照圖1與圖7，在本實施例中，假設測溫模組30的較佳量測距離為12cm，亦即溫度感測裝置10與活體50之間的距離在12cm下，測溫模組30所量測到的體溫值的誤差較小。From another perspective, the ranging function of the temperature sensing device can also be used to generate a trigger signal. For example, FIG. 7 is a flowchart of a temperature sensing method according to a tenth embodiment of the present invention. Referring to FIG. 1 and FIG. 7 together, in the embodiment, it is assumed that the preferred measuring distance of the temperature measuring module 30 is 12 cm, that is, the distance between the temperature sensing device 10 and the living body 50 is 12 cm, and the temperature is measured. The error of the body temperature value measured by the module 30 is small.

首先可由步驟S701，測距模組40偵測溫度感測裝置10與活體50之間的距離值。接著可由步驟S702，處理模組20依據測距模組40所提供的距離值產生一觸發訊號。更具體地說，當處理模組20判別距離值為12cm時，則可產生觸發訊號。接著，可由步驟S703，測溫模組30依據觸發訊號偵測活體50的體溫值。如此一來，使用者無須按壓按鈕，就可以觸發溫度感測裝置10對活體50進行體溫 量測，使用上更為方便。不僅如此，測溫模組30還可在較佳距離下，例如12cm，對活體50測溫，如此一來可降低誤差。再者，在習知技術中，使用者按壓按鈕的過程會搖晃溫度感測裝置10，可能會使測溫裝置30瞄準活體50的準心產生偏移，如此會使誤差變大。反觀，在本實施例中，使用者無須按壓按鈕就可以觸發測溫功能，如此可改善習知準心發生偏移的情況，降低誤差。First, in step S701, the distance measuring module 40 detects the distance value between the temperature sensing device 10 and the living body 50. Then, in step S702, the processing module 20 generates a trigger signal according to the distance value provided by the ranging module 40. More specifically, when the processing module 20 determines that the distance value is 12 cm, a trigger signal can be generated. Then, in step S703, the temperature measurement module 30 detects the body temperature value of the living body 50 according to the trigger signal. In this way, the user can trigger the temperature sensing device 10 to perform body temperature on the living body 50 without pressing the button. Measurement, more convenient to use. Moreover, the temperature measuring module 30 can also measure the temperature of the living body 50 at a preferred distance, for example, 12 cm, so that the error can be reduced. Furthermore, in the prior art, the process of pressing the button by the user may shake the temperature sensing device 10, which may cause the temperature measuring device 30 to be aimed at the alignment of the living body 50, which may cause an error. In contrast, in the present embodiment, the user can trigger the temperature measurement function without pressing the button, which can improve the situation in which the conventional center of gravity is shifted and reduce the error.

在第十實施例中，當距離值為12cm時，處理模組20會產生觸發訊號，但其僅是一種選擇實施例。在其他實施例中，也可以設定成距離值達一預設範圍值，例如13-15cm，處理模組20再產生觸發訊號。In the tenth embodiment, when the distance value is 12 cm, the processing module 20 generates a trigger signal, but it is only an alternative embodiment. In other embodiments, the distance value may be set to a preset range value, for example, 13-15 cm, and the processing module 20 generates a trigger signal.

又例如，也可以設定成距離值達多個預設值的其一時，例如8cm、12cm、16cm，處理模組20再產生觸發訊號。如此一來，使用者在使用上能更輕易執行測溫功能，處理模組20也可針對特定的距離進行不同的溫度校正，如此也可兼具溫度感測裝置10的準確度。For another example, the processing module 20 may generate a trigger signal when the distance value reaches a preset value, for example, 8 cm, 12 cm, and 16 cm. In this way, the user can perform the temperature measurement function more easily in use, and the processing module 20 can also perform different temperature corrections for a specific distance, so that the accuracy of the temperature sensing device 10 can also be combined.

綜上所述，本發明在溫度偵測裝置配置了測距模組，透過量測與目標物之間的距離，可使溫度感測裝置的溫度量測更準確或降低溫度感測裝置的耗電量。另外，本發明的實施例還具有下列優點：In summary, the temperature detecting device is configured with a distance measuring module, and the distance between the measuring object and the target can be measured to make the temperature measuring device more accurate or reduce the temperature sensing device. Electricity. In addition, embodiments of the present invention have the following advantages:

1.透過數位濾撥、類比濾撥或光學鏡片的濾波，可降低雜訊對溫度感測裝置的干擾。1. Through the filtering of digital filtering, analog filtering or optical lens, the interference of noise on the temperature sensing device can be reduced.
