摘　　要：为了能够实现对温室集群的智能控制,设计并实现了一种基于RS 485总线搭配Modbus协议的温室集群监控系统。该系统由现场数据采集及控制部分、远程监控中心监控软件部分和通信协议部分组成。利用在RS 485总线上搭配Modbus协议实现监控中心主机与各个温室的微控制器通信。结合温室环境控制的特点,利用Zig Bee技术组成无线数据采集网络,使用S3C6410处理器实现对继电器的控制,利用BP神经网络PID控制算法,从而达到温室环境的智能控制。使用Qt软件设计人机交互界面,实现对温室集群的远程控制。实验结果表明,该系统能够正确采集温室环境的温度、湿度和光照强度等参数,并且能够通过控制继电器的动作对各个温室的环境参数进行有效的控制。In order to realize the intelligent control of the greenhouse cluster,a greenhouse cluster monitoring system basedon RS 485 bus and Modbus protocol was designed and implemented. The system is composed of the field data acquisition andcontrol part,monitoring software of remote monitoring center,and communication protocol. The communication between the mon?itoring center and the individual greenhouse is realized by collocation of RS 485 bus with Modbus protocol. Combined with thecharacteristics of greenhouse environment control,the ZigBee technology is adopted to constitute a wireless data acquisition net?work,S3C6410 processor is used to control the relay,and BP neutral network PID control algorithm is utilized to achieve the in?telligent control of greenhouse environment. The Qt software is used to design the man?machine interface to realize the remotecontrol of the greenhouse cluster. The experimental results show that the system can correctly collect the temperature,humidityand light intensity in the greenhouse,and can effectively control the environmental parameters of the greenhouse by controllingthe action of the relay.
