Stratum fracture monitoring and pre-warning system and method

Abstract

The invention discloses a stratum fracture monitoring and pre-warning system and method, and relates to the technical field of geological prospecting. The system comprises a sensor module, a wireless communication module, a data processing module and a positioning pre-warning module, wherein the sensor module consists of a plurality of MEMS (Micro-electromechanical System) digital acceleration sensors; the wireless communication module is used for transmitting feedback electromotive force generated by the sensor set to the data processing module; the data processing module is used for processing acquired data, comparing monitored earthquake impact with a set pre-warning threshold value and then transmitting a pre-warning signal to the positioning pre-warning module to prompt a worker. The system and the method have the beneficial effects that the data is acquired and processed by using the wide MEMS digital acceleration sensors, the cost is low, the later debugging and maintenance of the system are extremely convenient, the stratum fracture condition can be monitored in real time, the position of a stratum fracture is accurately positioned and the worker is timely prompted to achieve a pre-warning effect, and the monitoring accuracy is high.

Description

technical field [0001] The invention relates to geological exploration technology, in particular to a formation fracture 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 forms of geological disasters are mainly manifested in collapses, landslides, mud-rock flows, geological subsidence, subsidence, etc., especially road subsidence caused by stratum cracks, causing huge losses to people's lives and property. [0003] 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 monitor...

Problems solved by technology

[0003] 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 operations, and the traditional method of manual recording and manual calculation method, the cost of manpower and material resources is large, and the manual operation is greatly affected by the geographical environment and weather, and the personal safety of the operating personnel cannot be completely guaranteed; The amount of collection is small, and the monitoring data is difficult to accurately describe, so the accuracy of monitoring is low; it often takes a long time to process the monitoring data from manual data collection, which makes the monitoring results have a certain lag and delay Therefore, it is impossible to monitor and warn geological disasters in a timely and rapid manner, so that it cannot effectively prevent geological disasters in advance; 4. The existing monitoring methods cannot realize all-weather and dynamic monitoring, so the The location and time of geological disasters may not be able to obtain early warning information of geological disasters in time, so early warnings cannot be issued in time to avoid the loss of a large number of people and property
