Abstract

The invention discloses a PCB version identification device, comprising: a PCB version unit for marking PCB version information; and a PCB version state unit for detecting and storing the PCB version information. The invention also discloses a PCB version identification method. Adopting the present invention can not only ensure the forward compatibility after the software is upgraded, but also does not need to upgrade the logic version just because of the PCB version identification problem.

Description

technical field [0001] The invention relates to a communication equipment PCB version identification technology, in particular to a PCB version identification device and method. Background technique [0002] Modern society relies more and more on communication, and a large number of communication devices with different functions form the communication system of modern society. Communication equipment can be divided into terminal communication equipment and system communication equipment. Mobile phones, telephones, etc. belong to terminal communication equipment, and program-controlled switches, routers, etc. belong to system communication equipment. The system communication equipment is the core of the entire communication system. At present, the system communication equipment generally adopts the system structure of motherboard and plug-in board. The advantages of this system structure are flexible configuration and strong scalability. PCB (Printed Circuit Board) is an es...
