本發明係關於一種量測電壓及電流之治具及其量測方法，特別是一種應用於個人電腦系統，並可據以決定電源供應器規格之量測電源之電壓及電流之治具及其量測方法。The invention relates to a fixture for measuring voltage and current and a measuring method thereof, in particular to a fixture for applying a voltage and current of a power supply according to a specification of a power supply device, which is applied to a personal computer system and Measurement method.

個人電腦(personal computer，PC)已成為現代人生活中不可或缺的一部份。一般消費者購買個人電腦，可以向品牌業者購買整機式的個人電腦設備，品牌業者並提供售後服務；另外，也有一些中高階使用需求的消費者，或是為了效能的考量，或是為了節省購入成本，而傾向以自行組裝的方式，在分別買進電腦的組成部件以及軟體使用版權之後，再加以組裝為一部完整的個人電腦。目前國內也有不少網咖業者，為了節省硬體購入成本，而傾向於以自行組裝的方式購入電腦。Personal computers (PCs) have become an indispensable part of modern life. The average consumer buys a personal computer, can purchase the whole machine-type personal computer equipment from the brand owner, and the brand industry provides after-sales service. In addition, there are some consumers who use the medium-to-high-end demand, or for the sake of performance, or for It saves the cost of purchase, and tends to assemble itself into a complete personal computer after separately purchasing the components of the computer and the copyright of the software by self-assembly. At present, there are many Internet cafes in China who tend to purchase computers by self-assembly in order to save hardware purchase costs.

然而當消費者在決定自行組裝個人電腦時，必須確定各個組成部件的規格是否可以相容，以期能順利組裝。其中電源供應器(power supply)的輸出功率規格，亦是一個在效能與價格之間的取捨之後的決定值。個人電腦中的電源供應器是用來提供供應電壓源，給個人電腦中主機板以及其他組成部件，例如硬碟機、光碟機、顯示卡等等。如果電源供應器的輸出功率規格不足，將容易造成掉電的問題，亦即電源供應器的輸出 電壓在動態使用時容易低於額定電壓值，而造成系統不穩定、當機、甚至是組成部件的損壞。However, when consumers decide to assemble their own PCs, it is necessary to determine whether the specifications of each component are compatible, so that they can be assembled smoothly. The output power specification of the power supply is also a decision after the trade-off between performance and price. The power supply in the personal computer is used to supply the voltage source to the motherboard and other components of the personal computer, such as a hard disk drive, a CD player, a display card, and the like. If the output power specification of the power supply is insufficient, it will easily cause the problem of power failure, that is, the output of the power supply. When the voltage is used dynamically, it is easy to be lower than the rated voltage, which causes system instability, crashes, and even damage to components.

然而電源供應器的輸出功率規格愈高，其價格也就愈昂貴，例如目前市面上輸出功率規格為350瓦特(Watt)以及500瓦特的電源供應器，其價差大於一千元；而往上一級來比較，500瓦特以及750瓦特的電源供應器，其價差甚至達到三千元。以這樣的市場價差，對於需要購置一定數量的個人電腦而又對於購入價格極為敏感的網咖業者而言，如何在盡量壓低價格的先決條件下，來決定剛好夠用的電源供應器的輸出功率規格，以購入適用的電源供應器組件，是一個重要的營業考量。然而，目前並沒有一個較有效率而方便的作法，來得到這個問題的答案。However, the higher the output power specification of the power supply, the more expensive it is. For example, the current power supply specification of 350 watts (Watt) and 500 watts on the market has a price difference of more than one thousand yuan; To compare, the 500 watt and 750 watt power supply, the price difference even reaches 3,000 yuan. With such market price difference, for those Internet cafes who need to purchase a certain number of personal computers and are extremely sensitive to the purchase price, how to determine the output power of the power supply just enough to minimize the price Specifications to purchase suitable power supply components are an important business consideration. However, there is currently no more efficient and convenient way to get the answer to this question.

一般而言，消費者在購入電源供應器時，皆傾向於較為保守的作法，亦即購置規格較高的電源供應器，以避免個人電腦系統在使用上產生問題。然而如此卻又造成了購置成本的多餘支出。In general, when consumers purchase power supplies, they tend to be more conservative, that is, purchase a higher-standard power supply to avoid problems in the use of personal computer systems. However, this has resulted in excess expenditure on acquisition costs.

微控制器170用以決定並控制主板電壓及電流量測電路121以及組件電壓及電流量測電路151進行量測電壓及電流的方式，例如量測開始的時機，以及以週期性或非週期性的方式進行量測。微控制器170並且接收主板電壓及電流量測電路121以及組件電壓及電流量測電路151的電壓及電流量測結果並進行處理，例如將電壓及電流量測結果儲存至位於微處理器內部或是外部的一儲存單元，或是即時地輸出至其他的量測設備以進行分析，例如經由通用串連匯流排(universal serial bus，USB)將資料輸出至作為量測設備控制端的筆記型電腦以進行記錄和分析。另外，目前市面上許多微控制器之積體電路亦整合了類比數位轉換器之電路於同一晶片中，因此可進行本實施例中主板電壓及電流量測電路121所包括的類比數位轉換的功能，此時主板電壓及電流量測電路121只需將電阻兩端的電壓訊號耦接至具有類比數位轉換功能之微控制器之積體電路即可。因此，本發明所揭露的實施例的說明中，微控制器乃作為概念及功能上的說明，並不限於是一個以積體電路實現的單一晶片。The microcontroller 170 is used to determine and control the manner in which the motherboard voltage and current measuring circuit 121 and the component voltage and current measuring circuit 151 measure voltage and current, such as the timing of the start of the measurement, and the periodicity or non-periodicity. The way to measure. The microcontroller 170 also receives and processes the voltage and current measurement results of the motherboard voltage and current measurement circuit 121 and the component voltage and current measurement circuit 151, for example, storing the voltage and current measurement results inside the microprocessor or Is an external storage unit, or is immediately output to other measuring devices for analysis, for example, via a universal serial bus (USB) to output data to a notebook computer as a measuring device control terminal.

In addition, the integrated circuit of many microcontrollers on the market also integrates the analog digital converter circuit in the same chip, so that the analog digital conversion function included in the motherboard voltage and current measuring circuit 121 can be performed in this embodiment. At this time, the motherboard voltage and current measuring circuit 121 only needs to couple the voltage signals across the resistors to the integrated circuit of the microcontroller having the analog digital conversion function.

第2圖為本發明所揭露之第二實施例之量測電源之電壓及 電流之治具101及其應用之個人電腦系統1000之電路圖。量測電源之電壓及電流之治具101與第1圖所揭示之量測電源之電壓及電流之治具100之不同處，在於量測電源之電壓及電流之治具101更包括了主板電壓指示燈181。主板電壓指示燈181與微控制器170電性連接。當微控制器170量測主板電壓之值為正常時，微控制器170發出訊號啟動主板電壓指示燈181。如此，使用者可藉由直接觀察主板電壓指示燈181的明滅，而直接判斷目前主機板1100所接收之供應電壓源其供電是否正常，以利量測工作中進行偵錯。Figure 2 is a diagram showing the voltage of the measuring power supply of the second embodiment of the present invention A circuit diagram of the current fixture 101 and its application to the personal computer system 1000. The difference between the fixture 101 for measuring the voltage and current of the power source and the fixture 100 for measuring the voltage and current of the power source disclosed in FIG. 1 lies in that the fixture 101 for measuring the voltage and current of the power source further includes the motherboard voltage. Indicator light 181. The motherboard voltage indicator 181 is electrically connected to the microcontroller 170. When the microcontroller 170 measures the value of the motherboard voltage to be normal, the microcontroller 170 issues a signal to activate the motherboard voltage indicator 181. In this way, the user can directly judge whether the power supply of the supply voltage source received by the motherboard 1100 is normal, by directly observing the clearing of the motherboard voltage indicator 181, so as to facilitate the debugging during the measurement operation.

另外，在第一實施例以及第二實施例中，微控制器170可以選擇性地由電源供應器1300進行供電，或是由外接供應電壓源(圖中未示)進行供電；而主板電壓及電流量測電路121或是組件電壓及電流量測電路151亦可以選擇性地由電源供應器1300進行供電，或是由外接供應電壓源進行供電。微控制器170、主板電壓及電流量測電路121以及組件電壓及電流量測電路151直接由電源供應器1300之供應電源進行供電，具有簡化整體測試電路以及所需設備(即不需一組外接供應電壓源)的好處，使得量測電源之電壓及電流之治具100、101在應用上具有更大的可攜性以及便利性。然而由於微控制器170、主板電壓及電流量測電路121以及組件電壓及電流量測電路151的耗電將可能加計於待測之個人電腦系統1000之耗電值當中，因而造成誤差。因此，當待測之個人電腦系統1000之耗電值遠大於微控制器170、主板電壓及電流量測電路121以及組件電壓及電流量測電路151之耗電時，微控制器170、主板電壓及電流量測電路121以及組件電壓及電流量測電路151直接由電源供應器1300之供應電源進行供電，並不致 造成量測結果太大的誤差；然而當待測之個人電腦系統1000之耗電值接近、甚至小於微控制器170、主板電壓及電流量測電路121以及組件電壓及電流量測電路151之耗電時，以外接供應電壓源對微控制器170、主板電壓及電流量測電路121以及組件電壓及電流量測電路151進行供電，方可排除誤差。值得一提的是，在本實施例中，微控制器170、主板電壓及電流量測電路121以及組件電壓及電流量測電路151可分別選擇其供電方式，例如微控制器170係由24針腳之12伏特電壓源進行供電，而主板電壓及電流量測電路121以及組件電壓及電流量測電路151則以外接電路進行供電。在實施例中所揭露之供電規劃方式係用以說明之用，使用者可依照實際應用上的需求，而有其他供電規劃上的設計。In addition, in the first embodiment and the second embodiment, the microcontroller 170 can be selectively powered by the power supply 1300 or powered by an external supply voltage source (not shown); The current measuring circuit 121 or the component voltage and current measuring circuit 151 can also be selectively powered by the power supply 1300 or by an external supply voltage source. The microcontroller 170, the mainboard voltage and current measuring circuit 121, and the component voltage and current measuring circuit 151 are directly powered by the power supply of the power supply 1300, and have simplified overall test circuits and required equipment (ie, no external set is required) The benefits of the supply voltage source make the fixtures 100, 101 for measuring the voltage and current of the power supply more portable and convenient in application. However, since the power consumption of the microcontroller 170, the main board voltage and current measuring circuit 121, and the component voltage and current measuring circuit 151 may be added to the power consumption value of the personal computer system 1000 to be tested, an error is caused. Therefore, when the power consumption value of the personal computer system 1000 to be tested is much larger than the power consumption of the microcontroller 170, the main board voltage and current measuring circuit 121, and the component voltage and current measuring circuit 151, the microcontroller 170 and the main board voltage And the current measuring circuit 121 and the component voltage and current measuring circuit 151 are directly powered by the power supply of the power supply 1300, and do not The error caused by the measurement result is too large; however, when the power consumption value of the personal computer system 1000 to be tested is close to or even smaller than that of the microcontroller 170, the main board voltage and current measuring circuit 121, and the component voltage and current measuring circuit 151 When the power is supplied, the external supply voltage source supplies power to the microcontroller 170, the main board voltage and current measuring circuit 121, and the component voltage and current measuring circuit 151 to eliminate the error. It should be noted that, in this embodiment, the microcontroller 170, the motherboard voltage and current measuring circuit 121, and the component voltage and current measuring circuit 151 can respectively select the power supply mode thereof, for example, the microcontroller 170 is composed of 24 pins. The 12 volt voltage source is powered, and the main board voltage and current measuring circuit 121 and the component voltage and current measuring circuit 151 are powered by an external circuit. The power supply planning method disclosed in the embodiment is for illustrative purposes, and the user may have other power supply planning designs according to actual application requirements.

再者，前述的量測設備控制端亦可載入各種不同規格之電源供應器之資料，並且在搭配量測電源之電壓及電流之治具100、101針對待測之個人電腦系統1000進行電壓及電流之偵測、紀錄以及分析之後，就某一規格的電源供應器得到是否適用的結論，亦即個人電腦系統1000的所需耗電是否超出所選定的電源供應器的規格，並就此一結論發出警示，例如以不同燈號警示，或是以螢幕畫面顯示結論。如此測試者可就適用的電源供應器之中，加上價格以及安全邊際的考量，選擇出適合消費者的電源供應器產品。Furthermore, the aforementioned measurement device control terminal can also load data of various power supply specifications of different specifications, and carry voltages for the personal computer system 1000 to be tested with the fixtures 100 and 101 for measuring the voltage and current of the power supply. And after the detection, recording and analysis of the current, it is concluded whether the power supply of a certain specification is applicable, that is, whether the power consumption of the personal computer system 1000 exceeds the specification of the selected power supply, and this is the same Conclusions Alerts, such as warnings with different lights, or conclusions on a screen.
