Among them, the mobile communication network is widely used in the area where the communication infrastructure is perfect, because of its wide coverage and flexible deployment. The system collects the water flow data of the river where the target water conservancy gate is located in real time through the mobile base station, processes it through the data analysis module, and determines whether to send the opening and closing gate instruction according to the preset threshold. The wired transmission mode has the advantages of stable transmission and strong anti-interference ability, and provides reliable communication guarantee for gate control in the area with short distance or laying conditions. Satellite communication link also undertakes data transmission task in some scenes, and tries to break through the geographical limit by using the wide coverage of satellite. However, these communication methods still have obvious defects when dealing with the control of dams in remote areas, mountainous areas or areas with weak communication infrastructure.
