Description

technical field [0001] The invention relates to the field of microseismic monitoring, in particular to a multifunctional integrated high-precision intelligent microseismic monitoring system, which is suitable for mining (coal mines and non-coal mines), oil and gas field development, water conservancy and hydropower and road traffic construction, reservoir water storage, nuclear waste Safety monitoring, evaluation and management of engineering disasters such as storage, underground storage of greenhouse gases, exploitation of seabed resources, rock bursts induced by national defense construction, roof collapse, ground pressure impact, landslides, and earthquakes. Background technique [0002] Microseismic monitoring technology is a new geophysical prospecting technology developed in the 1890s. The principle of this technology is to use sensors to collect vibration signals generated by the internal energy accumulated in the form of stress waves when rock cracks initiate, expand...

AI Technical Summary

Problems solved by technology

The A / D conversion digits of existing microseismic systems are generally 18 bits, and some have reached 24 bits. Although this can meet the needs of general monitoring, it is not enough for in-depth scientific research. More accurate microseismic signals will be picked up at that time. , microseismic source energy calculation, and damage source mechanism analysis, it is necessary to design a higher-precision A / D conversion acquisition instrument

The higher the number of A / D conversion digits and the higher the sampling frequency, the greater the load on the acquisition module, and it is difficult to effectively process some data in time, and even the data is lost; The higher the optimization requirements, the unreasonable configuration will lead to the collection of more background noise

[0008] 4) In order to ensure that more effective signals can be acquired, the existing microseismic system data acquisition mostly adopts the continuous acquisition mode. This acquisition mode does not set filtering conditions for the signal, and the amount of data is very large. Data transmission, storage and processing have always been a It is difficult to meet the needs of rapid analysis and early warning of rock engineering disasters
