Radio-based underground water level dynamic monitoring device and method

Abstract

The invention relates to the technical field of exploration, and particularly discloses a radio-based underground water level dynamic monitoring device and method, comprising a control module located at a monitoring wellhead and used for collecting underground water parameters, and a communication module installed at the monitoring wellhead and used for communicating with a control center, the monitoring modules are distributed at different positions in the monitoring well, and the transmission line is used for connecting the monitoring modules and the control module. According to the method, typical underground water dynamic parameters with relatively good seismic performance are selectively acquired, and underground water hydration anomaly key theoretical data for earthquake prediction are acquired under the condition that the number of monitoring wells is limited, so that original data are accumulated for earthquake prediction research and relevance between underground water hydration anomaly and earthquake; equipment in an existing monitoring well is simplified, the problem that the energy supply load of the monitoring well is large in the field environment is solved, and meanwhile theoretical data are provided for studying the change rule of dynamic parameters of underground water.

Description

technical field [0001] The invention relates to the technical field of surveying, in particular to groundwater information technology surveying, in particular to a radio-based groundwater level dynamic monitoring device and method. Background technique [0002] Earthquakes are a strong manifestation of crustal movement and tectonic activity. During the process of earthquake gestation and occurrence, it can cause changes in the structure, mechanics, and physical and chemical properties of deep and shallow media on a local or regional scale. As a ubiquitous and active component in the earth's crust, groundwater's dynamic changes can more sensitively reflect the information of seismic and tectonic activities. [0003] In the 1970s, earthquakes of Ms7.3, Ms7.2, and Ms7.2 occurred in Haicheng, Liaoning (February 4, 1975), Songpan, and Pingwu, Sichuan (August 16, 23, 1976) respectively. Before the earthquake, the water level of some wells rose and fell sharply, and the well wate...

AI Technical Summary

Problems solved by technology

[0005] In the actual use of existing groundwater dynamic monitoring devices, there are many problems: one is the energy supply problem. In order to obtain more comprehensive groundwater parameter data, existing groundwater dynamic monitoring devices often set as many as possible in a single measuring well Observation items, a variety of observation items means that multiple data collectors need to be arranged. Most of the existing observation wells are distributed in the field environment. The equipment with high power consumption consumes more energy, and the continuity of power supply is difficult to be guaranteed; the second is The probe is easily damaged. During the use of the existing multi-parameter water level detector, the detection probe is mostly soaked in water. The probe is periodically sampled and detected, and is not always in working condition, but the pressure hole of the probe is always open. After long-term use, the sediment in the water will block the pressure hole of the probe, resulting in a decrease in the measurement accuracy of the probe or damage; in addition, due to the limitation of the number of measurement wells and the distribution range, the data obtained by the detection and monitoring equipment in a single measurement well Cannot reflect the change of groundwater parameters in this area
