摘　　要：针对高校实验仪器设备维护与管理系统中存在的智能化、数字化程度不高和不便于远程控制等问题,本文介绍一种基于RS-485的电子设备检修系统的结构和实现方法。文中重点介绍系统结构、网络节点转换接口、网络通信协议及通信软件抗干扰措施的设计思路。实践表明,该系统具有可靠性高、通信速度快、抗干扰能力强等优点,有着广泛的应用前景。According to the problem, as colleges and universities laboratory are lack of high-degree intellectualized, digitized management system during maintaining their instruments and devices, and not convenient to realize long-range controls. This pa- per introduces a structure and implementation method of the eleetronie circuits troubleshooting skill system that is based on the RS-485 bus. The emphasis of this paper is the system structure, the switch of RS-232 and RS-485,the network communication protocol and software antijam design. Practice is indicated that this system has high reliahility, fast communicating speed and strong anti-interference ability, which has broadly applying prospect.
