Description

Method and system for monitoring water level of underground water super-mining area Technical Field The invention relates to the technical field of monitoring devices, in particular to a method and a system for monitoring the water level of an underground water super-mining area. Background The monitoring of the water level of the underground water super-mining area is a key work in water resource management and geological environment protection. The method has the core purposes of evaluating the super-mining degree, early warning ground subsidence and other geological disasters by continuously and accurately acquiring the dynamic water level data of the underground water, and providing scientific basis for formulating the underground water recharge and limited mining policies. The core of modern water level monitoring systems is their measuring and sensing unit, i.e. mechanical sensors (e.g. pressure sensors). These sensors convert the measured water level to the liquid pressure to which they are subjected, thereby producing an electrical signal that can be accurately measured. The intellectualization of the system depends on the technical architecture of the internet of things, and the architecture enables a monitoring device deployed on the site to automatically and continuously transmit the original data acquired by the mechanical sensor to a remote data center or a cloud platform in real time through a wireless network. Therefore, the intelligent monitoring device integrating the mechanical sensor and the Internet of things technology has the core application of converting the water level change which is difficult to directly observe into a continuous data stream which can be accurately measured, transmitted and analyzed remotely. The method provides key real-time and historical data support for the fields of water resource management, hydrogeology research, flood early warning, geological disaster prevention and the like. Through long-term stable operation, the system can accurately capture the dynamic change trend of the water level, and becomes an indispensable modern technical tool for grasping the water balance of the area and evaluating the super-mining condition. The invention of publication number CN102486392B provides a water level monitoring method for monitoring the water level of a subterranean well, in which three pressure sensors are placed at different depths of a liquid medium in the subterranean well in sequence at fixed distances to measure the pressure of the liquid medium at the different depths. However, the pressure sensor is immersed in well water for a long time, is easily covered and blocked by sludge, microbial films or mineral precipitates, and causes sensing misalignment of the sensing element, and data drift or complete failure. Secondly, frequent manual cleaning and maintenance are performed to ensure the data precision, so that the workload is large, the cost is high, and new errors can be introduced due to disturbance of the monitoring well. Finally, these technical limitations eventually lead to poor continuity and reduced reliability of the monitoring data, so that the management department cannot accurately grasp the real dynamic state of the underground water level, and thus, the real-time effective response to the super-mining risk is difficult.
