电子线路板卡自动检测系统输入输出扩展电路的设计

摘要

Based on extended circuit application requirements, the author uses the board automatic monitoring technology of input and output expansion circuit design were analyzed, combined with the various experiments, it was found that the board of the automatic detection technology has been widely used, but in practical application, because of the board's input and output interface more and different types, so the application and development of automatic detection system for board bring some trouble this conclusion. In view of this problem, this paper designs the circuit of automatic detection of input and output from the model of board input and output interface.%基于扩展电路应用需求，笔者采用了板卡自动监测技术对输入输出扩展电路设计进行分析，结合多方面试验得出板卡的自动检测技术已得到广泛应用，但在实际应用中，由于板卡的输入和输出接口较多，且型号各异，因此对板卡自动检测系统的应用和发展带来一定困扰这一结论。针对此问题，本文从板卡输入和输出接口的型号着手，设计了自动检测输入输出扩展电路，在实际运用中取得了成功。
