[摘要] 为了在园林浇灌中节约水资源、人力和使得园林植物更好的生长,设计和完善园林自动浇灌控制系统
具有非常重要的意义。该设计的核心是通过土壤湿度传感器检测到土壤的湿度,然后把测得的湿度这一模拟量通过AVR单片机中所带的A/D转换模块转换成数字量,进而再通过单片机控制显示即时湿度值,并且把当时湿度与事先设定值进行比较,如果湿度值低于设定值,单片机就会控制电磁阀产生动作,使得浇水泵打开自动浇水。当湿度值到达一定程度,电磁阀也会产生动作使得泵停止浇水。该系统结构简单,可靠,功耗较低,成本低,减少人力并使得园林植被更好的生长。

Abstract:In order to save water resources, manpower and make the garden plant better growth, design and improve the garden automatic watering control system has very important significance in landscape irrigation. The core of the design was detected by soil moisture sensor soil moisturethe measured humidity the analog quantity by AVR microcontroller A / D conversion module is converted into the digital quantity, and then through the single-chip microcomputer control and display the instantaneous humidity value, and the when humidity and a preset values are compared, if the humidity is lower than the set value, the microcontroller will control electromagnetic valve action, making watering pump open automatic watering. when the humidity reaches a certain degree, the solenoid valve will produce action makes the pump stop watering.The system structure is simple, reliable, low power consumption, low cost, reduce the manpower and the garden vegetation grow better.
