摘　　要： 针对农业温室分布地域广、分散的特点,设计了基于Modbus-RTU和GPRS通信的温室环境控制系统。系统由西门子S7-200 SMART PLC、触摸屏、GPRS模块和上位机服务器构成,利用Modbus-RTU采集现场温湿度、光照度等传感器的实时信号,并在触摸屏进行实时显示以及实现多种模式下的手动控制;通过GPRS模块把采集到的信息远程传送至上位机服务器,对信息进行接收和综合分析处理。现场测试表明,该系统结构设计合理、系统运行稳定,能够满足花卉温室远程监控的要求。 Aiming at the wide and scattered distribution of agricultural greenhouse, design the greenhouse environment control system based on Modbus-RTU and GPRS. The system consists of Siemens S7-200 SMART PLC, touch screen, GPRS module and host computer server, using Modbus-RTU to collect temperature and humidity, light and other sensors real-time signals,and display in the touch screen and realize the manual and automatic control. Through the GPRS module to collect the information, integrated analysis and processing. The results show that the reasonable design of the system structure, system function is stable, and can meet the requirements of remote monitoring of flower greenhouse.
