基于串口服务器的智能小区信息发布系统

为了使智能小区管理中心通过以太网将信息发布到各单元住户，应用串口服务器设计小区信息发布系统．系统利用串口服务器的协议转换功能，以Modbus和TCP协议的串口通信方式．将信息发布系统的终端——单片机控制系统接入以太网．应用测试表明，系统具有数据传输可靠、响应速度快、扩展灵活等特点，实现了智能小区的网络化管理．

Intelligent Uptowns Information Distribution System Based on Serial Port Server

Information distribution system of intelligent uptowns based on serial port server is discussed. The system connects the terminal devices based on singled-chip microcomputer to Ethernet by using serial port server. The determination method of parameters in the serial port server is discussed. The main idea for designing the system is described. The implementation of the software and hardware is introduced. By using serial communication based on Modbus and TCP protocols, it is tested that the system is reliable in data transmission, quick to response and flexible to extension. Network management on intelligent uptowns is achieved.
