A Network Temperature and Humidity Controller Design and Implementation

摘要:

针对现代新型建筑工程对节能和自动化控制的要求,设计了一个基于开源的TCP/IP协议栈uIP的网络温湿度控制器,该产品既可以作为独立的控制器,也可以作为RS485网络的路由器；该控制器的应用可以将建筑现场的执行器和传感器接入局域网,便于通过互联网方式集中控制与管理,使得温湿度环境数据采集和传输不再受采集控制终端数量、分布区域、传输距离等限制；该控制器中嵌入微型web服务,用户通过浏览器便可以实现实时准确地监控建筑体内的温湿度等情况,解决了数据访问对PC客户端程序的依赖,为其他系统解决方案提供条件；文章同时给出详细的电路图和软件流程图,对uIP协议的其他应用项目有一定的参考意义。

Abstract:

The Article designed a temperature and humidity controller based on the open source TCP/IP protocol stack uIP to meet energy-saving and automatic control requirements of the modern new construction. This product can be not only as independent controller, but also as the router of RS485 network. The application of the controller can connect the actuators and sensors to the network of construction spot, convenient for centralized control and management through Internet, making temperature and humidity data collection and transportation no more under the limit from the amount of collection control terminal, distribution area, and transportation distance and so on. Web service is embedded in the controller, user can realize monitor temperature and humidity situation inner construction real-time and accurately through browser, which solves the dependence of data access to the PC client program, provides conditions for the other solutions. Meanwhile, the paper provides detailed circuit diagram and software flow pattern, which has reference significance to the other application project of uIP protocol.
