针对传统温室灌溉水资源利用率低、无法满足作物适时适量、按需灌溉的问题,以单片机技术为核心,结合传感器、遥控技术,设计一种具有参数遥控设定、土壤水分实时采集显示、土壤水分调节、超范围声光报警等功能的控制系统。经试验,该系统工作可靠、控制精度高,能够根据温室作物需求适时适量、按需、自动灌溉,能够节约用水、节约人工成本,具有良好的应用价值。
In view of the low utilization rate of irrigation water resources in traditional greenhouse, it can not meet the requirement of timely and proper irrigation of crops and irrigation on demand. Based on the single-chip microcomputer technology, combining with the sensor and remote control technology, a remote control setting with parameters, real- Moisture regulation, ultra-sound and light alarm and other functions of the control system. After testing, the system is reliable and has high control precision. According to the needs of greenhouse crops, the system can timely and properly irrigate according to demand, which can save water, save labor cost and has good application value.
