Domestic articles RFID steady arm

Technical field

The utility model relates to the article steady arm, relates in particular to a kind of domestic articles RFID steady arm.

Background technology

Generally, the quantity of the various trifling article of one family surpasses thousand, does not use for a long time to cause losing or forgeing its deposit position.And because forgeing of people brings inconvenience also for the important every-day object of searching temporarily.

Along with human society enters the information age, people need intelligently the managing family article to make things convenient for daily life.

RFID (Radio Frequency Identification, radio-frequency (RF) identification) technology, claim again electronic tag, radio frequency identification, be a kind of automatic identification technology that begins to rise the nineties in 20th century, it utilizes radiofrequency signal to pass through Space Coupling (alternating magnetic field or electromagnetic field) and realizes that contactless information transmission and the information of passing through to transmit reach identifying purpose.

Rfid system is by comprising at least electronic tag and reader two parts.Electronic tag is the data carrier of radio-frequency recognition system, and electronic tag is comprised of label antenna and label special chip.According to the difference of electronic tag power supply mode, electronic tag can be divided into active electronic label, passive electronic label and half passive electronic label.Battery is housed in the active electronic label, and passive RF label does not have internal battery, and half passive electronic label partly relies on battery operated.Electronic tag can be divided into low-frequency electronic label, high-frequency electronic label, ultrahigh frequency electronic tag and microwave electron label according to the difference of frequency.Difference according to packing forms can be divided into special-shaped label of credit card label, linear label, paper shape label, glass tube label, circular label and specific use etc.RFID reader (read write line) carries out radio communication by antenna and RFID electronic tag, can realize reading or write operation tag recognition code and internal storage data.

Since the RFID reader when reading the RFID label intensity of read output signal be with RFID reader and RFID label between relative position relevant, the researchist can set up the model of the position coordinates of the intensity of related read output signal and RFID label accordingly like this.

Therefore, those skilled in the art is devoted to develop a kind of RFID steady arm, by using above-mentioned model, realizes the intelligence location of domestic articles, is convenient to the user and searches required domestic articles.

The utility model content

Because the defects of prior art, technical problem to be solved in the utility model provides a kind of RFID steady arm, read the RFID label of domestic articles by the RFID steady arm, and in conjunction with the model of the position coordinates of the intensity of related read output signal and RFID label, obtain the positional information of domestic articles.Voice module in the RFID steady arm makes this steady arm also have phonetic function.

For achieving the above object, the utility model provides a kind of RFID steady arm, it is characterized in that, comprise microprocessor, storer, rfid interrogator with omnidirectional antenna and directional antenna, load module, display module, voice module and touch display, described microprocessor links to each other with described storer, described microprocessor links to each other with described rfid interrogator, described touch display links to each other with described microprocessor by described load module, described microprocessor links to each other with described touch display by described display module, and described microprocessor links to each other with described voice module.

Further, described rfid interrogator carries out reading of identification code to the RFID label of domestic articles, receives the described signal of reading.

Further, the model that has the position coordinates of the intensity of the related described signal of reading and described RFID label in the described storer.

Further, described RFID label is passive electronic label.

Further, described RFID steady arm is portable RF ID steady arm.

Further, described RFID label is active electronic label.

Further, described RFID steady arm is fixed RFID steady arm.

Further, described RFID label is linear label, paper shape label, circular label or special-shaped label.

Further, described touch display is arranged on the shell of described RFID steady arm.

In better embodiment of the present utility model, when RFID steady arm of the present utility model is located the domestic articles with RFID label, at first open the omnidirectional antenna of rfid interrogator, read the identification code of the RFID label of all article in the aware space, and the identification code that receives and corresponding signal be sent to microprocessor, the model of the intensity of the signal that microprocessor is read by the association in the storer and the position coordinates of RFID label obtains the utmost point footpath coordinate ρ of all article in the aware space; Then open the directional antenna of rfid interrogator, read the identification code of the RFID label of all article in the aware space by changing directional angle scanning, and the identification code that receives and corresponding signal be sent to microprocessor, the model of the intensity of the signal that microprocessor is read by the association in the storer and the position coordinates of RFID label obtains the polar angle coordinate θ of all article in the aware space.Can obtain thus the position coordinates (ρ, θ) of all article in the polar coordinate system take the RFID steady arm as limit in the aware space of RFID steady arm of the present utility model, and be stored in the storer, thereby realize location to domestic articles.When the user searches article, input the title of the article of desired seek at the touch display of RFID steady arm of the present utility model, this information exchange is crossed load module and is sent to microprocessor, microprocessor searches the identification code to RFID label that should Item Title in storer, and corresponding position coordinates.Microprocessor is crossed display module with the information exchange of this position coordinates and is sent on the touch display.Preferably, can represent this position coordinates with the illustrated mode of solid space, thereby make things convenient for the user to check.In addition, in the process of locating and searching, the voice module of RFID steady arm of the present utility model can send the voice messaging that comprises prompting user operation under microprocessor-based control.
