计算机报警系统中接口电路研究

在计算机报警系统中 ,接口电路承担把外部信号准确传给计算机 ,同时把计算机指令输出并控制执行的双重功能 ,其输入输出功能的实现和准确可靠地工作对于整个控制系统都是非常重要的。本文对报警系统总线结构及接口模块进行充分地分析 ,在电路设计中采用编码技术和脉冲、电源复用技术 ,使电路优化、成本降低、运行稳定、兼容性好 ,较好地实现了输入及输出功能。

Study on Interface Circuit in the Warning System of the Computer

Among computer warning system interface circuit undertake and make outside signal accurate to infect with computer at the same time computer instruction export and double function that control carry out.It is very important that it inputs realization which exports the function and work accurately to the whole control system. This text fully analyse the bus structure of warning system and interface module, adopt the technology of the code and pulse, power to reply the technology of using during the design of circuit, circuit optimize, cost reduce, run steady, fine compatibility, better one realize and input and export the function.
