A shallow geological displacement monitoring and early warning system and method

Abstract

The invention relates to a geological exploration technology, in particular to a superficial layer geological displacement monitoring and early-warning system and a superficial layer geological displacement monitoring and an early-warning method. The system comprises a sensor module, a communication module, an information processing module and an early-warning module. When a geological accident occurs at the monitoring points, the angle sensor module can monitor the offset, the communication module transmits the monitored offset to the information processing module, the information processing module converts the offset into offset displacement, calculates the offset center and the average offset value of the monitoring point according to the offset displacement, judges whether the average offset value meets the early-warning condition or not and transmits triggering information to the early-warning module if the average offset value meets the early-warning condition, and the early-warning module sends out an early-warning signal according to the received triggering information. The monitoring and early-warning system and the monitoring and early-warning method are high in monitoring accuracy and realize all-weather and dynamic monitoring. The monitoring system is low in mounting, using and later maintenance costs. The monitoring and early-warning method is easy to operate and control and suitable for popularization.

Description

technical field [0001] The invention relates to a geological survey technology, in particular to a shallow geological displacement monitoring and early warning system and method. Background technique [0002] In recent years, due to the abnormal changes in the global climate, the hidden dangers of geological disasters are also increasing, especially with the intensification of human activities and the continuous expansion of the scope of activities, more and more geological damages are caused. The main forms of geological disasters are collapses, landslides, mud-rock flows, geological subsidence, subsidence, etc. The reason is that in addition to meteorological factors, shallow geological displacement is the main cause of geological disasters. [0003] At present, the traditional monitoring methods for geological disasters are mainly through group monitoring and group prevention and on-site participation of monitoring personnel.

Problems solved by technology

[0003] At present, the traditional monitoring methods for geological disasters are mainly through group monitoring and group prevention and on-site participation of monitoring personnel. The defects of these existing monitoring methods are: 1. These existing monitoring methods usually use manual operation, manual recording, manual The traditional method of calculation requires a large investment in manpower and material resources. At the same time, manual operation is greatly affected by the geographical environment and weather, and the personal safety of the operating personnel cannot be completely guaranteed; 2. Since the data is manually collected regularly, this makes The amount of monitoring data collected is small, and it is difficult to accurately describe the monitoring data, so the accuracy of monitoring is low; 3. It often takes a long time to process the monitoring data from manual data collection, which makes the obtained monitoring results have certain Therefore, the monitoring and early warning of geological disasters cannot be carried out in a timely and rapid manner, so that the function of preventing geological disasters in advance cannot be effectively played; 4. The existing monitoring methods cannot realize all-weather and dynamic monitoring , so at the location and time period where geological disasters are about to occur, early warning information of geological disasters may not be obtained in time, so early warnings cannot be issued in time to avoid the loss of a large number of people and property

[0004] In order to solve the problems existing in traditional monitoring methods, people have developed new technical means for monitoring shallow geological displacement, mainly including surface displacement deformation GPS measurement method, laser radar measurement method and synthetic aperture radar interferometry method, etc. These Monitoring means, the absolute displacement monitoring of shallow geological displacement has high accuracy, but the cost of monitoring equipment and maintenance costs used by these monitoring means are very high. In addition, the use of these equipment has very high quality requirements for monitoring personnel. Difficult to popularize widely
