摘要:

【目的】提高卷盘式喷灌机灌溉性能。【方法】通过模糊控制理论和方法实现对卷盘式喷灌机灌溉系统的智能控制，以土壤湿度偏差和土壤湿度偏差变化率作为系统的输入量，以桁架车牵引速度作为系统的输出量，通过对系统的两个输入量进行模糊处理，运用模糊推理运算，获得桁架车牵引速度的模糊值，最后将模糊结果清晰化处理，得到桁架车牵引速度的真实值，并通过电机驱动实现喷灌机桁架车的行进。【结果】当土壤湿度偏差和土壤湿度偏差变化率较大时，喷灌机桁架车牵引速度较慢，可以增加灌水量；当土壤湿度偏差和土壤湿度偏差变化率较小时，喷灌机桁架车牵引速度较快，可以减少灌水量。【结论】针对不同的土壤湿度和土壤湿度偏差变化率，系统可以改变喷灌机桁架车牵引速度，进而改变灌水量，达到对作物进行精准灌溉的目的。

Abstract:

【Objective】This paper aims to improve the irrigation performance of hose reel irrigators. 【Method】The intelligent control of the hose reel irrigators system is realized by fuzzy control theory and methods, with the soil moisture deviation degree and deviation change rate as the input values of the system, and the sprayer cart traction speed as the output values of the system, through the fuzzy processing of the two input values of the system, the fuzzy inference operation is used to obtain the fuzzy value of the traction speed of the hose reel irrigators. Finally, the fuzzy result is clear processing, and the real value of the traction speed of the hose reel irrigators is obtained, and the moving of the hose reel irrigators is realized by the motor drive.【Result】When the soil moisture deviation and the change rate of soil moisture deviation were large, the traction speed of the sprayer cart was slow, and the irrigation could be increased.When the soil moisture deviation and the change rate of soil moisture deviation are small, the traction speed of the sprayer cart is faster, and the irrigation can be reduced. 【Conclusion】According to different soil moisture deviation and the change rate of soil moisture deviation, the system can change the traction speed of the hose reel irrigators, and then change the intensity of sprinkler irrigation, so as to achieve the purpose of precision irrigation of crops.
