Underground water level monitoring and early warning system

Abstract

The invention provides an underground water level monitoring and early warning system, a detection system is divided into a wellhead part and an underground part, a non-contact water level sensor, a pressure sensor and a liquid specific gravity sensor are installed on the underground part, the underground part freely moves under the dragging of a right-angle worm direct-current gear motor and a cable, and a liquid specific gravity sensor is installed on the underground part. The water surface position in an underground water detection well is comprehensively judged through the pressure sensor and the non-contact liquid level sensor, meanwhile, the length of a cable between the underground part and the wellhead part at the moment is judged through the absolute encoder, and the water level information of deep underground water is comprehensively calculated in combination with elevation data in the Beidou system. And the accuracy of detection data is improved. And the water level information is sent to a server through the 4G data transmission module or the Beidou short message module, so that a data center can inquire and monitor the water level information.

Description

technical field [0001] The invention relates to a remote automatic detection system for deep underground water level detection wells in the field. Background technique [0002] Groundwater resources are not only important natural resources related to national production, but also a factor directly related to major natural disasters. Therefore, it is necessary to monitor the water level information of deep groundwater resources in real time. Different from surface water resources, the detection of water level information of groundwater resources is usually realized by digging water level detection wells, which can usually be divided into automatic detection and manual detection. However, according to the distribution of groundwater resources, the location of detection wells is often in the In the wilderness or deep in the mountains. The manual detection method is inefficient and cannot meet the needs of real-time monitoring, and it also poses a great threat to the safety of ...

AI Technical Summary

Problems solved by technology

The principles of the above two detection methods are essentially similar, but it is difficult to eliminate the deviation caused by groundwater quality and regional elevation information

[0004] At present, the water level information detected by the automatic detection device is usually transmitted through the 3G / 4G wireless network to the data monitoring center. However, at remote detection points, the wireless network communication signal is usually extremely poor, and it is difficult to ensure that the system data can be transmitted back in a timely and accurate manner. to the server, affecting the real-time performance and accuracy of the detection system
