摘要
计算机监控系统广泛应用于众多领域,其接口技术则关系到整个系统的可靠性。本文对监控系统常用的串行接口和网口作了详细的研究,包括其硬件特性和软件技术,及接口之间的硬件转换和软件转换的实现,最后给出了一个通过Internet进行远程测试的实例。
The computer monitor systems are almost used in every area in nowadays,and the interface technique is the key essential to the reliability of systems.This paper describes the RS232/422/485 and RJ45 in detail,including the hardware features and software techniques,and the conversion between them by hardware and software.Finally,there is an example about computer remote test through Internet.
