摘　　要：为充分发挥卷盘式喷灌机的水力性能,降低喷灌机能耗,并实现喷灌机喷洒速度的自动控制,以电驱动代替水涡轮驱动,并开发了智能控制系统.采用太阳能系统供电,永磁无刷直流电动机驱动卷盘,设计了基于MSP430F169单片机为检测和控制核心的驱动控制系统.该系统主要包括太阳能充电控制器,电动机控制器,隔离电源模块,电动机电压、电流检测模块,蓄电池电量检测模块,电动机霍尔测速模块,卷盘转速和回卷层检测模块以及键盘和液晶模块.研制了各模块软硬件,实现了对卷盘各项运行参数的测量显示和喷洒车移动速度的自动控制,试验结果表明,该智能驱动控制系统运行稳定,能实现喷洒车的匀速回收.该系统为实现卷盘式喷灌机变量灌溉提供了有效地实现方式和技术手段.For the purpose of improving the irrigator hydraulic performance and energy use efficiency, as well as realizing the automatic speed eontM of sprinkler cart, which would be a headache under wa- ter turbine driven system, an intelligent control system was developed for the motor driven hose reel irrigator. The developed control system employed a high efficiency solar energy powered Brushless DC Motor （BLDCM） to drive the reel. A contM system based on the single chip microcomputer MSP430F169 was developed to control the DC motor and detect the system status as well. The control system mainly consisted of the solar cha-ge controller, the BLDCM controller, the isolated power mo- dule, the motor voltage and current detect module, the battery capacity detect module, motor speed detect module, the reel speed and rotating layer detect module, and the microcomputer module. The solutions of each function module were described in detail, which were combined to realize the auto- matic speed control of the sprinkler carriage and the operational parameters detection of the hose reel irrigator. The field test shows that this intelligent drive control system operates stable and the sprinkler carriage can be drawn back in a set speed constantly. This proposed system is an effective fundamental technique for the variable rate irrigation research of hose reel irrigator.
