Abstract


Aiming at the application of the experimental system of earth temperature monitoring, this study designed a ZigBee technology-based wireless sensor network (WSN) and designed the network topology according to actual demand. The system adopted a tree network model and used the CC2430 as the core chip of the wireless communication network of temperature measuring system. Moreover, DS18B20 temperature sensor was used to collect temperature data. According to the preset routing protocol, the temperature data obtained were uploaded to the coordinator node via the router node by multiple hops. The temperature data collected by coordinator node were transformed to the host after being processed. Applying the Cluster-Tree and AODVjr optimized routing algorithm, this system showed the advantages of low complexity, easy deployment, high efficiency, good real-time performance, low power consumption, and convenient for long-time work. In addition, it provided powerful support for the real-time monitoring of farmland experiment system.
