Description

Technical Field

[0001] The present invention relates to the technical field of water resource monitoring, and in particular to a comprehensive monitoring device for hydrological and water resource metering monitoring. Background Art

[0002] Hydrology and water resources monitoring is used by water departments to monitor water extraction from their own wells, monitor water inflow and outflow from water plants, monitor open channel flow, monitor groundwater levels, monitor water quality at water sources, and conduct remote water sales management. It plays an important role in effectively protecting water resources, rationally utilizing water resources, and enhancing social awareness of water conservation.

[0003] At present, in order to facilitate the monitoring of open channel flow and the collection of hydrological data, a monitoring station is generally set up at a certain distance on both sides of the open channel. The existing monitoring stations are generally equipped with radar water level meters. The main measurement principle is to transmit radar pulses from the radar water level sensor antenna, and the antenna receives the pulses reflected from the water surface and records the time T. Since the propagation speed C of electromagnetic waves is a constant, the distance D to the water surface is obtained, thereby monitoring the water level. The collection of hydrological data is often carried out regularly by manual labor.

[0004] The existing monitoring devices have relatively single functions, and comprehensive monitoring of hydrological and water resources data is rather troublesome. In addition, the radar water level meter of the monitoring device is generally exposed to the air. Once a bird collides with the radar water level meter, it is easy to cause damage to the radar water level meter, resulting in monitoring errors of the radar water level meter, thereby affecting the accuracy of data monitoring. Summary of the invention
