| Abstract: |
| Irrigation gates play an important role in the regulation of water resources in large-scale irrigation districts. In order to realize the intelligent control of channel water delivery, this paper adopts automatic control, information communication and sensor technology to design and develop a set of measurement and control gate system for irrigation area based on the Internet of Things(IoT) and PLC. The system is mainly composed of on-site integrated measurement and control gate terminals and IoT based remote monitoring system. Using open channel flow measurement theory and sensor technology, the measurement of channel water level and gate opening is realized. Rack and pinion is used as gate opening and closing mechanism to improve gate operation efficiency. The gate terminal controller based on S7-200 PLC is developed to realize the automatic control and wireless communication of the on-site gate terminal have been developed. The gate remote monitoring system software based on the IoT technology has been developed to realize the remote monitoring of the gate and the management of data. The system realizes the remote intelligent control of the canal gates, has the characteristics of high measurement accuracy, strong stability, convenient operation and maintenance, and is suitable for precise control of the water delivery and distribution process of small and medium-sized channels in irrigation areas. |
