Li Zhou, Shu Hui Zhang, Yan Dong Song · Applied Mechanics and Materials · 2013
The rational database including the distribution, changes and testing facilities status of temperature & humidity in tea garden is created using the MapInfo 9.5. A set of the tea garden wireless utilities is established using the ZigBee module. The temperature & humidity real-time monitoring system and early warning system for Frost Prevention is established using Mapbasic. This system can get real-time information of temperature & humidity of nodes in different locations and give frost warning early. The frost prevention fans can be timely started, once temperature inversion happens. At the same time, the manager of tea garden can realize real-time monitor of the work status and quick location of facilities with the help of GPS.
