Formation fracture monitoring and early warning system and method

Abstract

The invention discloses a formation fracture monitoring and early warning system and method, which relate to the technical field of geological exploration and include a sensor module, a wireless communication module, a data processing module and a positioning early warning module; the sensor module is composed of a plurality of MEMS digital acceleration sensors, The wireless communication module is used to transmit the feedback electromotive force generated by the sensor group to the data processing module; the data processing module processes the collected data, compares the monitored seismic impact force with the set early warning threshold, and then locates the early warning module Signal, the positioning early warning module sends out an early warning signal to prompt the staff. Beneficial effects of the present invention: the present invention uses a wide range of MEMS digital acceleration sensors to collect and process data, the cost is low, and the later debugging and maintenance of the system are very convenient, and it can monitor the situation of formation cracks in real time, accurately locate the position of formation cracks and notify in time The staff play the role of early warning, and the monitoring accuracy is high.

Description

Technical field [0001] The invention relates to geological prospecting technology, in particular to a stratum crack monitoring and early warning system and method. Background technique [0002] In recent years, due to the abnormal global climate change, 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 have been caused. The forms of geological disasters are mainly manifested in collapses, landslides, mudslides, geological collapses, settlements, etc., especially the road subsidence caused by stratum cracks, causing huge losses to people's lives and property. [0003] The traditional monitoring methods of geological disasters are mainly through group monitoring and prevention and on-site participation of monitoring personnel. The disadvantages of these existing monitoring methods are: 1. The existing monitoring methods usuall...

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
