In the technical scheme provided by the application.

First, it relates to RFID read-write devices.

In the description of the present application, it has been explained that: the RFID read-write equipment emits 860 MHz-960 MHz ultrahigh frequency electromagnetic wave.

In the prior art, when transmitting electromagnetic waves, the RFID read-write device can also carry other instruction information (also sent out in the form of electromagnetic waves). The RFID-related device having such a function (a function capable of sending out an electromagnetic wave command) is a common device in the field, the communication principle and the interaction manner between the RFID read-write device and the RFID tag are disclosed, and those skilled in the art can implement the technical solution of the present application in combination with the basic function when implementing the present application.

For example, in the related textbooks, the above technical principles have been disclosed. The authors include Sinong gan, Sino Yufeng, Yao Qian, etc.; the publishing company is an electronic industry publishing company; the publication date is 2015, 01 months and 01 days; ISBN number 9787121246685; the technical principles mentioned above have been disclosed in textbooks entitled "Radio Frequency Identification (RFID) principles and applications (2 nd edition). The teaching material is a twelve-five planning teaching material for common higher education, and the publication date is earlier than the application date of the application, so that the teaching material can be used as the technical basis of the application.

In the above teaching materials, chapter 9 is the microwave RFID technology. The frequency bands mainly describe the relevant contents of the frequency bands of 433MHz, 860-960 MHz, 2.45GHz and 5.8 GHz. Wherein the content of the frequency band of 860-960 MHz is just suitable for the application.

Chapter 9.4 of the teaching material describes a microwave transponder (corresponding to the combination of the RFID chip and the RFID antenna of the present application). In the microwave transponder, the energy obtaining mode of the microwave transponder comprises the following steps: firstly, the transponder is obtained only from radio frequency energy, and the transponder does not have a battery at the moment; the transponder is provided with an additional battery, but only provides chip running energy, and communication energy is still obtained through radio frequency; and the battery provides the energy for the chip to operate and communicate. Wherein, the method is suitable for the case of no battery; and (c) are applicable to the case with a battery in the application.

Indeed, as a practical solution, one skilled in the art may use the passive transponder chip XRAG2 in the teaching material 9.4.2 to implement the technical solution of the present application. The XRAG2 chip is a passive RFID transponder integrated circuit chip working in UHF frequency band, and has complete functions and low power consumption. The carrier frequency range of the chip is 860-960 MHz, and frequency use specifications of North America, Europe and other regions and countries are covered; the received signal is an asynchronous Pulse Width Modulated (PWM) 90% SSB-ASK, DSB-ASK or PR-ASK modulated signal (data transmission rate up to 128kbps), in response to FM0 and Miller bit coded reflection modulated signal (data transmission rate up to 640 kbps); having read, program, and erase functions, etc.

From the above, it can be confirmed that the RFID read-write device provided in the present application can emit electromagnetic waves with ultra-high frequencies of 860MHz to 960 MHz.

Second, with respect to RFID antennas.

The RFID chip has four storage areas, respectively: i TID area: the chip identification number is used for storing the unique chip identification number; reserved area (Reserved area): read keys, write keys, destroy keys, and the like are usually stored; ③ EPC area: storing the number written by the user (the factory default value is the same, and the number is generally the only number after the user writes), and the number is used for rapidly checking the number of the tags; USER area: other data written by the user is stored.

In general, the RFID read/write device reads information in the EPC area, that is, the RFID read/write device issues an instruction to read information in the EPC area in the form of electromagnetic waves, all RFID chips in the read area of the RFID read/write device can respond by the tag antenna and feed back information in the EPC area of the chip, and the feedback information can be received by the RFID read/write device.

And thirdly, communication interaction between the RFID read-write equipment and the RFID chip is related.

1. The RFID read-write equipment has a group scanning and group reading function. When reading group scanning, reading the EPC area information of all RFID tags within a certain range to form an EPC set, and on this basis, selecting one of the tags in the EPC area ═ x "to perform an additional operation, for example, reading the Reserved area information, and for example, writing a piece of information in the USER area or modifying all USER information, which is a technical method for operating one of the RFID tags by using RFID reading and writing equipment. When the RFID read-write device continuously and uninterruptedly repeats an operation, for example, screening a tag with EPC ═ 123456789, continuously operates and reads the fourth bit in its Reserved area, and the RFID read-write device does not stop the operation until an instruction to stop reading is issued, during this period, the RFID read-write device continuously transmits electromagnetic waves to a certain area, and the RFID antenna in the area can convert the energy of the electromagnetic waves (magnetic field) into electric energy, and the basic principle of a generator that cuts magnetic lines of force to generate current is used here. The RFID tag can utilize the electric energy according to the chip instruction: (1) as a responder, feeding back information of each area in the chip to the read-write equipment through an antenna per se; (2) modifying information stored in a certain area; (3) energizing the LED chip with current generated by the magnetic field to light it (please refer to chip description "KX 2005X-BL Datasheet _ CN" of Kalrowei technologies, Inc. of Sichuan); (4) other working instructions of the tag chip.

2. When the RFID reading and writing equipment reads the RFID label, one or more operation instructions can be carried at the same time, received by the RFID antenna and analyzed and executed by the RFID chip.

3. The RFID label chip is divided into four areas, which are respectively: TID zone, Reserved zone, EPC zone, USER zone (the zone is omitted by individual manufacturers to reduce cost). Generally, specific data is written in the EPC area by a user before the RFID tag is used, and when the RFID read-write device scans the RFID tag, the specific RFID tag can be found according to the specific information written in the EPC area.

The examiner indicates in the reject notification that the RFID reader/writer device is indifferent reading, and the applicant does not disagree, and the indifferent reading of the RFID reader/writer device is the group-scan group-read function described above, and the group-scan group-read by the RFID reader/writer device is only a basic function of the RFID reader/writer device, and only reads the EPC areas of all the RFID tags in the read area, so that the feedback of all the RFID tags in the area can be obtained, and the read manner can obtain the quantity information of all the RFID tags in the area.

However, not negligible are: the RFID read/write device also has the capability of operating a certain tag independently, and also belongs to the basic capability of the RFID, that is, in an electromagnetic wave instruction transmitted by the RFID read/write device, a certain single tag with specific data in the EPC area is screened, and a series of operations are performed on the tag through the RFID read/write device according to an upper application (for example, a mobile phone APP or a PC program, etc.), for example, data in the USER area is modified, for example, a write control key of the tag is modified, for example, a destruction key is reset, for example, a fourth bit in the Reserved area of the tag is read (on a chip of KX2005X-BL Datasheet CN of kawayy technologies, ca, sich, the operation can trigger a chip to power up two pins of the tag and light an LED), and the like, which belong to the operation of the RFID read/write device on a certain RFID tag.

For example: when the group scanning group reading is carried out, the RFID reading and writing equipment sends out electromagnetic waves to read EPC areas of all RFID labels, all the RFID labels can feed back information to be obtained by the RFID reading and writing equipment, and the feedback information is recorded at the same time, so that the number of the RFID labels in the reading area can be counted, the number statistics of the articles attached to the labels can be obtained, and the RFID labels can be used by people in actual production life.

The principle of making the LED on a specific electronic tag emit light is as follows:

when the RFID read-write device performs group scanning group reading, if an instruction of "EPC area ═ is added, all RFID tags in the area may be filtered, and the result of group scanning group reading is: only the tags in the EPC area are read by the RFID reader/writer (there may be only one tag or a plurality of tags, and it is assumed herein that the EPC areas of the RFID tags of the storage device are different, and only the case of screening one tag is discussed). Then, the RFID reader/writer device reads (reads for the second time) the specific tag (i.e. the found tag), and carries an instruction to read the fourth bit in the Reserved area (see chip description of KX2005X-BL Datasheet CN of kawawei technologies, inc., of kawa), so as to turn on the LED of the specific tag. Specifically, a parameter "EPC ═ x ×" is added to a read command issued by the RFID read/write device, and a tag in which information written in the EPC area in the area is "×", is screened. After the RFID reading and writing device searches the tag, it will send a command to the specific RFID tag again, and this command will add a command to read the Reserved area, specifically, the convention of the chip command in this method is to read the fourth position in the Reserved area, then the RFID tag of "EPC ═ x" will energize the chip pin connected with the LED according to this command, at this time, the induced electric energy generated by the RFID antenna will drive the LED lamp to flash through the pin, thus completing the function of searching the specific tag and reminding and positioning the specific tag. Please refer to chip description documents of "keluiway LED passive electronic tag instruction V1.0" and "KX 2005X-BL Datasheet CN".

In the above principle and the description of the work flow, the RFID reader/writer may transmit an instruction (in the form of an electromagnetic wave) which is received by the RFID chip, and the RFID chip may perform a corresponding action according to the instruction (the corresponding action has two aspects, on one hand, feeding back information to the RFID reader/writer, and on the other hand, changing the pin level of the RFID chip to drive whether the LED lamp is turned on or not), and simultaneously may generate an induced current by the induction of the RFID antenna, that is, the RFID chip drives the prompting device to start to send a prompting signal (the LED lamp is turned on herein).

The utility model discloses in, the built-in energy of RFID read write line equipment can send away the energy with the electromagnetic wave signal form, then converts electromagnetic wave signal into the electric energy after receiving electromagnetic wave signal by the RFID antenna, and the RFID chip is provided with two pins and is connected with the suggestion device, and the electric energy that the RFID antenna converted just can drive the suggestion device and start.
