摘　　要：针对低矮花卉浇灌系统成本较高、温湿度控制滞后的问题,对其自动控制部分进行了设计和改进。浇灌系统主要由单片机、参数采集模块、浇水模块、远程控制模块、报警模块和显示器组成。浇灌系统通过采用时间序列预测方法预测土壤温湿度,采用CUSUM算法检测土壤温湿度是否偏离预测值,以保证浇灌过程中土壤的温湿度始终在最适宜范围。为验证该低矮花卉浇灌系统的性能,对其进行试验,结果表明:浇灌系统可预测土壤温湿度变化,对花卉浇灌系统进行自动控制,且节水性能良好。Aiming at the problem of high cost and control delay of temperature and humidity to the irrigation system, the automatic control system based on low-growing flowers watering was studied and improved. The irrigation system was constituted of singlechip, parameter acquisition module, watering module, remote control module, alarm module and displayer. To keep the soil temperature and humidity in the optimum range, the irrigation system forecast the temperature and humidity in the method of time sequence prediction, and detect whether temperature and humidity deviated from the predicted values in the method of CUSUM arithmetic. To verify the property of low flower irrigation system, the tests were done. The test results show that the irrigation system could forecast the variation of the soil temperature and humidity, could control the flower irrigation system automatically, and the water-saving performance is well.
