基于无线传输的粮仓温湿度远程监测系统
Remote detection system of granary temperature and moisture based on wireless transmission
摘要
Abstract
A remote detection system of granary temperature and moisture was designed based on ZigBee technology to resolve problems such as wiring difficulties, poor scalability and high cost which exist in the traditional monitoring systems. CC2430 chip was used to build the Zigbee star network and every ZigBee device software was designed based on Z-Stack which was made by TI company. Basic function such as temperature and humility data acquisition was completed by the ZigBee terminal node. The data was sent to ZigBee coordinator by ZigBee website service and moisture coordinator sent data to server by RS232 serial. Moreover, database and web services were configured in the server to storage data and provided http service for remote PC. Workers can check temperature and moisture data and then control data acquisition from remote PC by http service. The correction and reliability of communication data were verified. The experiment showed that the temperature error was less than±0.4% and humility error was less than± 1.0%.The results showed that this system not only transmitted data accurately and securely, but also had advantages such as better real-time, higher reliability and lower energy consumption.关键词
