ZigBee网络。In the remote detection of orchard environmental parameters, gateway nodes suffer from two deficiencies that remain to be solved: short transmission distance of ZigBee module due to electromagnetic interference; failure to meet the dynamic configuration of ZigBee network. The hardware design adopted the structure of kernel board plus motherboard and modularized interface to improve antielectromagnetic interference performance. The software design adopted two strategies, i.e. serial programming and single thread communication, to realize dynamic configuration of ZigBee network. To reduce energy consumption of the system, gateway nodes decided whether to upload data according to the difference between consecutivelyreceived data and the variation tendency. The test results indicated that gateway nodes could realize stable data acquisition and remote data transmission. Due to the improvement of antielectromagnetic interference performance, communication distance was doubled compared with the design of integrated circuits board. Moreover, the ZigBee network could be configured flexibly and dynamically.
