单片机网络控制系统

基于Web的单片机远程监控系统采用两级分布式控制方式，其现场控制级采用单片机系统，完成现场参数的采集和控制．监控级为通过串行通信口与现场单片机系统进行数据通信和进行数据处理的监控计算机，该监控计算机还作为远程服务器．通过网络与远程计算机连接．远程计算机通过Internet访问服务器实现对现场设备的远程控制．

The Distributed Network Control System with Technique of Monolithic Computer

This paper presents a classical application of a distributed network control system. The system is composed of two parts.One is the process control subsystem performed by monolithic computers which collect and process the locale datum.The other is the monitoring subsystem performed by a monitoring computer which communicates with the locale process control subsystem through RS-232 port.Then the datum from the locale process control subsystem can be displayed and processed by a monitoring computer.The given value of the system can be set and sent to the locale process control subsystem. Connecting remote computers through Network,the monitoring computer is also used as a remote server.Then remote computers can interview the server and remotely control the locale devices through Internet.
