Monitoring system of soil water content based on zigbee wireless sensor network

为了提高农业灌溉用水利用率,针对传统有线网络采集布线复杂和成本高的缺点,该文设计了一套基于Zigbee无线网络和CC2430MCU的土壤墒情监测系统。该系统综合了Zigbee无线网络自行组网、自行愈合和超低功耗的优点,采用太阳能电池供电,能实时监测和记录土壤墒情信息,为进一步制定节水灌溉策略提供有力的数据支持。初步试验结果表明,该系统运行稳定,丢包率低,能及时准确的监控土壤墒情信息,并将土壤含水率维持在适合植物生长的最佳含水量的范围之内。研究结果可为进一步开发更精准的自动灌溉系统提供数据支持。

The main objective of this research is to improve the utilization rate of agricultural irrigation water with a soil moisture monitoring system based on Zigbee wireless network and CC2430 MCU. Unlike the complex wiring and costly wired network, ZigBee is a new mesh networking standard, which has the advantages of self-network-forming, self-healing and ultra-low power consumption. This solar-powered system realized real-time monitoring and recording of soil moisture information, which could provide data supports for further water-saving irrigation strategy planning as well. The system has been developed and tested with the ZigBee mesh network topology. Results showed that the system has high stability and low packet loss rates. This system could record the soil moisture of irrigated areas timely and accurately and keep the moisture among the scope which is suitable for the plant growth. The research results can provide references for further development of precise irrigation.
