Development of Monitoring Management System and Data Synchronization for Greenhouse IOT

为实现温室环境信息高效监测,开发了物联网测控管理系统的通用平台,主要包括基于Android的智能网关以及基于Google Web Toolkit的远程Web服务器,并制定了系统的数据同步通信协议。根据数据采集单元配置信息和预先设定的界面显示风格,智能网关和Web服务器的应用程序能够自适应地生成温室环境监测界面,动态地解析监测传感器数据并实现数据库存储,以Http post网络传输机制实现数据采集单元配置信息、监测传感器数值等数据在二者间的同步。试验结果表明温室物联网系统在实际应用中具有较高的稳定性,有效地避免了由于传感器和数据采集单元节点变更导致Web服务器和智能网关应用程序的二次开发。

In order to realize the high efficient monitoring of environment information, a kind of common monitoring management system of the internet of things （lOT） for greenhouse was introduced. The system mainly consisted of an intelligent gateway based on Android system and a remote web server based on Google Web Toolkit. Also the monitoring data synchronous communication protocol between the gateway and remote web server was formulated. According to the data acquisition unit configuration information and the preset display stile of the interface, the monitoring interface was adaptively generated by the gateway and server application program, the sensor data was dynamically parsed and the data storage in database was realized. Using the http post transmission mechanism, the applications of gateway and web server also realized the data synchronization of monitoring sensor parameters data and data acquisition units configuration information transmitted on the internet. The test results showed that the greenhouse IOT system and data synchronous communication were of high stability in practical application, and it can effectively avoid second software development which resulted from the changing of sensors or data acquisition unit nodes. The system achieved the function of monitoring management and data synchronization for greenhouse IOT system, and it provides a common platform for greenhouse intelligent monitoring and control.
