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。
Web-based multi-greenhouse automatic control and information distribution system adopts hierarchical design mode and uses PLC as the core of on-site control to collect environmental parameters such as temperature, humidity and light in intelligent greenhouse. Divided data processing technology and on-site fuzzy control strategy Automatic control of the operation of the implementing agencies, the use of configuration software for remote control and monitoring, the use of Web technology as a greenhouse information release platform, the use of RS485 bus and computer network to transfer system data. The test results show that the system has the characteristics of friendly interface, simple operation, high implementation efficiency and timely information release, and has good promotion value.
