基于单片机的韦根信号的接收

Reception of the Weigand Signal Based on Single Chip Microcomputer

介绍了韦根的概念和标准韦根26-bit信号的定义格式,依据其特点设计了一个韦根接收读卡器电路,并提供了程序实现的部分代码。该设计的电路和程序均已通过调试并在实际项目中得到应用。

The definition of the Weigand signal is given in the paper, which introduces a simple and practical reception circuit. Meanwhile, it provides the interruptive reception procedures and the parity programs for Weigand code. The circuits and programs have both passed the debugging.
