基于CAN总线和GPRS的温室大棚监控系统设计

Design of Greenhouse Monitoring System Based on CAN and GPRS

针对大规模、大空间温室大棚的监控管理不便、采集数据不及时等问题,设计了一种可以多点采集数据,并可以远程监控的温室大棚监控系统。本系统主要由数据检测节点、CAN总线和GPRS通信网络、上位机监控软件组成,数据检测节点用于检测温室大棚环境数据,环境数据通过CAN总线和GPRS通信网络上传给上位机;上位机监控软件用于数据的接收显示和管理,采用Visual Basic工具进行开发,并使用Access2010建立了数据库。本系统可以分布式采集多点环境数据,实现数据远程传送,并自动调节环境参数,适于专业大户、合作农场使用。

In order to solve the problems such as inconvenience of monitoring and management and not timely data collection for large scale and large space greenhouse, a greenhouse monitoring system which can collect data through multiple nodes and can be monitored remotely is designed. This system is mainly composed of data monitoring terminal, CAN and GPRS communication network, host computer monitoring software. Data monitoring terminal detects greenhouse environment data, then monitored data will be uploaded to the host computer through the CAN and GPRS communication network, and be displayed and managemeted by computer monitoring software, that is developed by using Visual Basic tool and the database is established by using Access 2010. The system can collect multi-point environmental data, and realize remote data transmission, and automatically adjust the enviconment parameters, which is suitable for both professional big clients and cooperative farms.
