Control Method of Farmland Automatic Sprinkler Irrigation Based on Wireless Sensor Network

为了优化农田自动喷灌控制效果,提高喷灌质量,实现均匀精准喷灌,引入无线传感器网络,开展了基于无线传感器网络的农田自动喷灌控制方法研究。首先,选择TCG-19010型号的土壤温湿度无线传感器,将传感器探头分别布置在农田作物正下方与空地土壤中,采集并记录农田土壤温湿度数据。其次,设计无线传感器网络架构,实时监控并获取待喷灌控制区域内的各项环境数据,并将数据发送给终端用户,为喷灌控制提供数据支持。在此基础上,根据作物需水量与土壤湿度,调节喷灌设备的性能参数,进行农田自动喷灌控制。结果表明,应用所提方法后,6块农田实验场地的喷灌均匀度均达到了规范要求的75%以上,能够实现均匀喷灌,提高了喷灌质量。

In order to optimize the control effect of automatic sprinkler irrigation,improve the quality of sprinkler irrigation and realize uniform and accurate sprinkler irrigation,wireless sensor network is introduced,and the research on automatic sprinkler irrigation control method based on wireless sensor network is carried out.First,select the TCG-19010 model soil temperature and humidity wireless sensor,and the sensor probe is arranged directly below the farmland crop and in the open field soil,to collect and record the farmland soil temperature and humidity data.Secondly,the wireless sensor network architecture is designed to monitor and obtain various environmental data in the area to be sprinkler control,and send them to the end user to provide data support for sprinkler control.On this basis,according to the water demand of crops and soil humidity,the performance parameters of the sprinkler irrigation equipment are adjusted,and the farmland automatic sprinkler irrigation control is conducted.The results show that after applying the proposed method,the uniformity of sprinkler irrigation in all 6 farmland experimental sites has reached over 75% of the standard requirements,which can achieve uniform sprinkler irrigation and improve the quality of sprinkler irrigation.
