As the intelligent core unit of open channel management in irrigation district, automatic gate integrates gate actuator, high-precision sensor array, advanced electromechanical control system, stable power supply module and efficient communication system to realize comprehensive automatic control and accurate measurement of channels. The system can collect key data such as water level and flow rate in real time, and automatically adjust the opening degree and opening and closing state of the gate according to the preset target flow parameters, so as to ensure the accuracy and efficiency of water flow management. The integrated gate of intelligent measurement and control not only provides detailed water usage records, helping users to accurately grasp the use of water resources, but also supports the dual management mode of local direct control and remote network monitoring. Through the network platform, users can view the status of the gate and monitor the dynamic flow anytime and anywhere, so as to realize the convenience and real-time management. The introduction of the gate greatly improves the intelligent control ability of the channel and the mouth, and is a key step to promote the informatization management level of the irrigation district. Combined with intelligent sensors in field layout, a complete intelligent irrigation and drainage system is built. The system can automatically adjust irrigation and drainage strategies according to the specific water drawing needs of different crops, so as to achieve accurate and scientific irrigation operations. This intelligent irrigation and drainage method not only effectively saves water resources, but also promotes the healthy growth of crops and improves the efficiency and sustainability of agricultural production.
