| 摘 要： | 为准确判断作物需水量并确立合适的灌溉控制策略，实现作物的自动、定位、实时与适量灌溉，设计了基于ZigBee无线传感网络与模糊控制方法的精细灌溉系统。该系统通过ZigBee无线传感器网络采集土壤水势与微气象信息（包括环境温度、湿度、太阳辐射与风速等），并传输灌溉控制指令；结合FAO56 Penman-Monteith公式计算农田蒸散量，并将农田蒸散量和土壤水势作为模糊控制器的输入量，建立了多因素控制规则库，实现了作物灌溉需水量的模糊控制。试验结果表明该系统经济实用、通信可靠、控制准确性高，特别适用于中小型灌溉区域的精细灌溉。

| Abstract: | In order to accurately determine the crop water requirement and the proper strategy of precision irrigation, and reach real-time and automatic irrigation with proper quantities of water in place, a precision irrigation system based on ZigBee wireless sensor networks (WSN) and fuzzy control technology was designed. The ZigBee-WSN was used to transmit the irrigation control signal, collect the soil water potential signal and micrometeorological informations including air temperature, relative humidity, solar radiation, wind velocity and so on. The soil water potential and crop evaporation calculated using the FAO56 Penman-Monteith equation were taken as input variables of fuzzy controller, and the multiple-factor control regular database was established for the fuzzy irrigation control system. The fuzzy control of crop irrigation water requirements was realized. The test results show that the system has many advantages, such as economic, practical, with high communication reliability and control accuracy. Especially, this system is quite appropriate for medium and small-sized precision irrigation areas. |
