基于网络的多温室自动控制及信息发布系统设计

Design of Multi-greenhouse Automatic Control and Information Release System Based on Network

基于网络的多温室自动控制及信息发布系统采用分层设计模式,使用PLC作为现场控制核心,实现智能温室的温度、湿度和光照等环境参数的采集,并使用离异数据处理技术和现场模糊控制策略自动控制执行机构的运转,使用组态软件进行远程控制和监控,使用Web技术作为温室信息发布平台,使用RS485总线和计算机网络混合的方式传递系统数据。试验结果证明,系统具有界面友好、操作简单、执行效率高、信息发布及时的特点,具有良好的推广价值。

Multi-greenhouse automatic control and information release system based on network adopt the hierarchical design model,and used PLC as the control core.It could collect the environment parameters of intelligent greenhouse such as temperature,humidity and light atc,and used the separated data processing technology and the fuzzy control strategy for automatic control of the actuator.It also used configuration software for remote control and monitoring,practical web technology as a greenhouse information publishing platform,practical way of compound of RS485 bus and the computer network data transmission system.The results proved that the system had characteristics of friendly interface,simple operation,high efficiency and the information release in a timely manner.So this system had well popularization value.
