摘要
对用于农场自动灌溉的远程智能控制器进行合理设计,可以在农业灌溉时减少大量的人力和物力,提高农业灌溉的效率。传统的控制器针无法有效控制灌溉时的水流量,造成了水资源不必要的浪费。设计一种新型用于农场自动灌溉的远程智能控制器,首先对远程智能控制器的总体结构进行描述,在湿度传感器设计、步进电机电路设计、阀门模型构建的基础上,将模糊控制器作为远程智能控制器中的核心部分。对土壤湿度信息进行采集和滤波处理,将处理的结果传输模糊控制器中,将模糊逻辑运算形成的驱动信号传输至上位机,通过上位机对步进电机进行控制,调控阀门开度的大小,完成于农场自动灌溉的远程智能控制。实验结果表明,与传统的控制器相比,设计的控制器控制精度和稳定性较高,可以将阀门开度变化保持在理想状态内,说明本文控制器具有较强的实用性,可以适用于大范围的农场自动灌溉。
Farm irrigation automatically remote intelligent controller for the reasonable design can be used in agricultural irrigation, reduced a lot of manpower and material resources, improved the efficiency of agricultural irri- gation. Traditional controller needle can not effectively control the irrigation water flow, causing unnecessary waste of water resources, a new type of remote intelligent controller was designed for farm irrigation automatically, de- scription of the overall structure of the remote intelligent controller is first of all, the humidity sensor design, stepper motor circuit design, the valve model building, on the basis of the fuzzy controller as a core part of remote intelligent controller. For soil moisture information gathering and filtering processing, will deal with the results of the transmission of fuzzy controller, the fuzzy logic operation of drive signal transmission is the highest place machine, through the PC to control stepping motor, control the size of the valve opening, completed in farm remote intelligent control of automatic irrigation. The experimental results show that compared with the traditional controller, the controller designed high control precision and stability, and can keep the valve opening change within the ideal state, shows that this controller has strong practicability, can be applied to a wide range of farm irrigation automatically.
