Small electronic tag of electric power communication circuit board

Abstract

The invention relates to a small electronic tag of an electric power communication circuit board. A design of an upper layer and a lower layer is adopted in the tag. The upper layer of the tag is an antenna and used for receiving wireless radio frequency signals emitted by the outside. The lower layer of the tag is an EPC-JY-2013 type 915Mhz radio frequency chip. A 32-bit hexadecimal EPC unique code is arranged in the chip. The antenna is connected with the EPC-JY-2013 type 915Mhz radio frequency chip. After the chip receives a radio frequency signal emitted by an external reading device, through radio frequency signal sensing, the working power supply is obtained and the antenna sends the EPC unique code in the EPC-JY-2013 type 915Mhz radio frequency chip to a radio frequency signal end. According to the invention, unique identification of identity information of the communication circuit board is finished; through the reading device, information of the circuit board is wirelessly acquired; identification, searching and inventory counting of circuit boards are achieved; and accuracy and high efficiency of checking of the communication circuit boards are improved.

Description

technical field [0001] The invention relates to an electronic label for circuit board identification management used in the field of electric power communication, and has a miniaturized circuit structure, which can meet the use of circuit boards of various specifications and models. Background technique [0002] Reserve circuit boards is one of the must-do tasks for electric power communication majors, but the management is very extensive, and it still stays in the mode of manual recording. We can only roughly grasp the types and quantities of boards and which warehouse they are stored in. Key node information such as the performance of the board, the specific storage location, the production period, and the maintenance history cannot be intuitively obtained. Lacking the identification basis of the circuit board, it is impossible to grasp the operating cycle of the board from production to scrap.
