針對我國農(nóng)業(yè)具有偏遠(yuǎn)、分散、易變、多樣等特點，提出一種基于 ZigBee 無線網(wǎng)絡(luò)
作物環(huán)境監(jiān)測系統(tǒng)的實現(xiàn)方案。采用低功率PIC 系列單片機(jī)PIC18LF4620 作為微控制器，
射頻收發(fā)芯片選擇有較強抗干擾性的Chipcon 公司CC2420 芯片，并采用AODV 算法解決
路由問題，最終實現(xiàn)一個低復(fù)雜度、低成本、低功耗的監(jiān)測系統(tǒng)。通過對溫度、濕度、光照等環(huán)境因子的監(jiān)測，能夠滿足對作物種植環(huán)境進(jìn)行實時監(jiān)測的要求，具有一定的實用價值。

Application of ZigBee in Monitoring System of Crop Planting Environment DAI Yuan YANG Long HE Dong-Jian （Northwest A & F University, Yangling, Shannxi, 712100,China） Abstract:According to our country’s agriculture with the characters of farness、disperse、 inconstancy、and multiplicity, this paper proposed a kind of design proposal of wireless sensor network based on ZigBee technology. MCU PIC18LF4620 and RF module CC2420 are used to establish the sensors network . The system adopts the algorithm of AODV to slove the problem of routing. Finally, a monitoring system of low-complication 、low-cost and low-power is implemented. It satisfies the demand of real time monitoring system of crop planting environment by monitoring temperature、humidity、illumination and other information. It has practicality value.
