Background
With the continuous acceleration of the construction pace of distribution automation in China, various distribution terminals are applied in a large scale. The failure indicator is a product, whether the product is qualified or not after the production is completed, and needs to be subjected to a series of strict tests to verify the quality and performance of the product. In recent years, the number of applications and requirements of fault indicators is very large, and the actual investment is about 20000 per year in Hunan province. According to the requirements of the power company, all equipment must pass strict tests before being installed on the site, and can be used on the site after the tests are qualified.

Detailed Description
The embodiments of the invention will be described in detail below with reference to the drawings, but the invention can be implemented in many different ways as defined and covered by the claims.
In order to achieve the above object, the present invention provides an RFID-based indicator management system, referring to fig. 1, including an RFID tag read-write management system 3, a two-dimensional code scanning gun 1, an RFID read-write controller 2, and an RFID tag printer 4, where the two-dimensional code scanning gun 1 is used to read an indicator two-dimensional code and record account information read from the two-dimensional code into the RFID tag read-write management system 3, the RFID tag printer 4 is used to print indicator information stored in the RFID tag read-write management system 3 to an RFID tag 5 for identifying and managing the indicator, and the RFID read-write controller 2 is used to read and write information stored in the RFID tag 5.
Referring to fig. 2, when a manufacturer issues a fault indicator to a user, basic information of the indicator is first stored in a two-dimensional code, for example, the two-dimensional code is attached to a machine body or an external package, and a position for attaching the RFID tag 5 is reserved on the machine body according to the requirement of the user, and the position needs to be striking, easy to replace and convenient to scan. The use unit needs to set the RFID tag read-write management system 3, and the information of the ledger of the fault indicator, such as the manufacturer, the production date, the factory number, the use unit, the installation position, the communication parameters, etc., can be entered into the RFID tag read-write management system 3. After receiving the fault indicator, the user scans the two-dimensional code label stored with the basic information of the fault indicator through the two-dimensional code scanning gun 1, and inputs the scanned basic information into the RFID label read-write management system 3, wherein the input mode can be that the basic information is uploaded to the RFID label read-write management system 3 in real time through the two-dimensional code scanning gun 1 with a wireless internet access function, and can also be stored in an internal memory of the two-dimensional code scanning gun 1 after the scanning is finished, and then the basic information is uploaded to the RFID label read-write management system 3 through a local communication mode such as a data line. Besides the information read by the two-dimensional code scanning gun 1, some necessary information can be manually input into the RFID tag read-write management system 3. Then, the information of the fault indicator is printed to the RFID label 5 by connecting the RFID printer with the RFID label read-write management system 3, the information of each indicator corresponds to one RFID label, and the printed RFID label 5 can be repeatedly read, written or erased. The printed RFID tag 5 is attached to the RFID tag 5 attachment site reserved for the indicator for a subsequent series of information processing and adjustment.
The RFID tag read-write management system 3 is also connected with an external fault indicator automatic test system to correlate test result information of the fault indicator. For a fault indicator newly input into a management system, the main functions, the performance and the like of the equipment need to be detected, and if the fault indicator is directly applied on site without detection, the qualification and the operation reliability of the equipment after being put into use are difficult to ensure. When the fault indicator is sent to the fault indicator automatic test system for detection, the printed RFID tag 5 can support remote reading and writing, and has no requirement on the position, so that the detection progress condition of each device can be mastered in real time and updated in real time in the control background of the automatic test system. After the fault indicator is tested, the information of the RFID tag 5 is read when the fault indicator leaves from the automatic test system, and is associated with the test result, whether the test is qualified or not is automatically identified, and the qualified products and the unqualified products are separated. Meanwhile, the fault indicators are stored in a classified mode according to the test result information, the fault indicators with qualified test results are stored in a qualified product area, and qualified product inspection management is carried out; and storing the indicator with the detection result of being unqualified into an unqualified product area, and managing the unqualified product. When the indicator is delivered from the warehouse, the RFID read-write controller 2 scans the RFID label 5 to obtain the indicator information, and if the qualified area is mixed with unqualified products or the unqualified area is mixed with qualified products, the information can be read out through the RFID label 5, so that manual intervention is performed on the previous error, and the error is corrected. The RFID read/write controller 2 can also read or modify the information of the product after the product is put into use, and the information can be modified by the RFID read/write controller 2 if the use warehouse of the product changes or the use time needs to be modified. The data modified by the RFID read-write controller 2 can be synchronized to the RFID tag read-write management system 3 in real time. Of course, the remote modification can also be directly performed through the RFID tag read-write management system 3.
Preferably, the RFID tag read-write management system 3 is also connected with an external fault indicator automatic test system to correlate the test result information of the fault indicator.
All the fault indicators entering the warehouse need to be detected, and only the detected fault indicators can be put into use. The automatic test system of the external fault indicator is associated with the RFID label read-write management system 3, so that the fault state can be stored in the RFID label read-write management system 3 in real time. The systems used by the RFID tag read-write management system 3 and the external fault indicator automatic test system are both systems developed independently.
Preferably, the information stored in the RFID tag 5 includes any one or a combination of a model code, an ID number identification code, a software/hardware version number, a manufacturer code, and production date information.
Preferably, the RFID tag read-write management system is an RFID tag read-write management system with an encryption function.
The RFID label read-write management system can read and write, so that the RFID label read-write management system is easily changed by people. After the RFID tag read-write management system is encrypted, only a user who has a secret key and inputs a correct secret key during data writing can change the data in the RFID tag read-write management system, and a user who does not have the secret key can only read the data to watch the data but cannot change the data.
The above is only a preferred embodiment of the present invention, and is not intended to limit the present invention, and various modifications and changes will occur to those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
