The equipment detects the water level of the monitoring site, and gives an alarm when the water level of the monitoring site exceeds the standard. However, affected by other factors, such as the size of the rain and the drainage status of the drainage system, the water level changes in real time, and the water level changes when the water level exceeds the standard. Alarm is a relatively rough monitoring method. In some monitoring schemes, the video data of the scene is captured and the complex algorithm is used to analyze whether flood control is required. However, this scheme usually requires a complete set of flood control monitoring. Only equipment and systems can be realized, and the price is expensive. It is only used in some large-scale comprehensive monitoring points, and is not suitable for household and civilian use.
