基于GPRS网络的育苗温室远程监控系统研究

Study on the Seedling Greenhouse Remote Monitoring System Based on GPRS

提出了一种用于育苗温室环境及工作参数远程监控的技术系统,由下位机和服务端组成,通过GPRS网络进行数据通信。下位机采用STM32单片机开发,通过多种数字式传感器采集温室数据,并对热水阀门进行控制;服务端采用监控程序采集数据、数据库存储数据、WEB页面显示数据的工作模式。系统中,数据通信采用MODBUS标准化协议,具有良好的可扩充性。测试结果表明:系统运行正常,数据传输可靠,能够满足育苗温室远程监测的要求。

This paper proposes a remote monitoring system for seedlings greenhouse environment and working parameters . This system consists of subordinate computer and server components , and GPRS network is used for data communication . Subordinate computer is developed based on STM 32 to gather remote data through a variety of digital sensor and control the hot water valve .The server adopts such a work mode in which data is collected by monitoring procedures , stored into database and showed in WEB page .The format of the data accord with MODBUS protocol standard , so that the system has good scalability .The test results show that the system is in normal operation , data transmission is reliable , and meets the requirements of greenhouse remote monitoring .
