【摘要】 为实现温室大棚群的环境监测及控制,设计了温室大棚环境检测及智能控制系统,可用手机或台式机远程通过单点接入对半径2.5km内多个温室大棚实现远程监控功能。设计网关单点接入互联网,通过485总线连接区域内多个大棚并进行监控。每个大棚有独立的系统检测大棚中CO₂浓度、温度、湿度、光照强度以及土壤中的温度和湿度;设计智能算法对每个大棚实现独立控制,包括电加热系统、灌溉水泵、通风风机、CO₂浓度、保温卷帘的动作以及植物补光的控制。系统经过现场测试,对单个大棚环境信息获取大概在15秒左右可以完成,远程控制指令从下发到完成操作在5秒内完成,大棚温度控制误差在±1Co左右。终端用户能够远程通过云平台单点接入实现对区域内各自的大棚完成环境参数监测与设备控制。更多还原

【Abstract】 In order to fulfill the environmental monitoring and control for the greenhouse group, a greenhouse environment detection and intelligent control system is designed. A mobile phone or desktop can be used to remotely monitor multiple greenhouses within a radius of 2.5 km through single point access. A gateway designed and connects to the Internet at a single access point, monitors multiple greenhouses in the area through the 485 bus. Each greenhouse is designed with an independent system to detect CO2 concentration, temperature, humidity, light intensity and temperature and humidity in the soil; design intelligent algorithm to achieve independent control for each greenhouse, including electric heating system, irrigation pump, ventilation fan, CO2 concentration, movement of thermal insulation roller blind and plant light supplementary control. After on-site testing, the system can obtain the environmental information at a single greenhouse about 15 seconds. The remote control command is issued to complete the operation within 5 seconds. The temperature control error in greenhouse is about ± 1 Co. End users can through the cloud platform remotely achieve single point access to complete the environmental parameter monitoring and equipment control to each respective greenhouses in the area.更多还原
