以Ｅｔｈｅｒｎｅｔ，ＲＳ４８５网络和电话网等常见网络技术为基础，设计并实现了一种分布式监控系统。介绍了如何根据不同的通信方案，选择合适的监控子系统及子系统的构成和实现方法。该系统根据不同距离和环境条件选用不同的网络技术，根据具体控制条件及技术要求采用不同的控制系统，从而实现了分散系统的集中监控。该系统适用于对实时性要求不同、地域分散的多个小系统的监控。
Based on common network technologies such as Ethernet, RS-485 network and telephone network, a distributed monitoring system is designed and implemented. Introduced how to choose suitable monitoring subsystem and subsystem according to different communication schemes. The system uses different network technologies according to different distances and environmental conditions, adopts different control systems according to specific control conditions and technical requirements, and thus achieves centralized monitoring of decentralized systems. The system is suitable for monitoring of multiple small systems with different real-time requirements and geographical scattered.
