Embodiment Construction

[0014] See figure 1 , a microseismic signal acquisition system, including a plurality of sensor modules 1, a plurality of signal adjustment modules, an STM32 signal processor 4 and a host computer 5; a plurality of signal adjustment modules 2 are connected to each sensor module 1 correspondingly, and the signal adjustment The module includes an amplifier 2 and a filter 3 connected to each other. The amplifier 2 is connected to the sensor module 1, and the filter 3 is connected to the STM32 signal processor 4. The sensor module 1 uses a JF-20DX-10Hz earthquake detector; the amplifier 2 uses an amplifier AD8574; Filter 3 selects fourth-order Butterworth active low-pass filter.

[0015] Working principle of the present invention:

[0016] The sensor module 1 collects the microseismic signal, the microseismic signal is amplified and filtered by the amplifier 2 and the filter 3, and after being converted by the STM32 signal processor 4A / D, a digital signal is obtained, and the dig...

Abstract

The invention discloses a micro-seismic signal collection system. The micro-seismic signal collection system comprises a sensor module, a signal regulation module, an ADC (Analog to Digital Conversion) module and an upper computer which are sequentially connected. According to the micro-seismic signal collection system disclosed by the invention, data can be analyzed and processed through the upper computer according to a micro-seismic signal collected by the sensor module, thus an accident or a natural disaster can be early warned, and the loss brought by the disaster can be reduced to a large extent. The micro-seismic signal collection system disclosed by the invention has the advantages tat the collection and transmission data volume is large, the transmission speed is quick, the reaction is sensitive, the anti-jamming ability is strong, and the reliability is high.

Description

[0001] technical field [0002] The invention relates to the field of data signal acquisition, in particular to a microseismic signal acquisition system. Background technique [0003] With the rapid development of the global economy and scientific and technological research, microseismic monitoring technology has also been rapidly applied and developed at home and abroad. Many fields use this system for related real-time monitoring, such as mines (mines), tunnels, oil drilling, anti-smuggling, Automotive engine fault monitoring, footstep recognition, etc. Before the rock collapse occurs in the mine, before the bridge breaks, and before the tunnel collapses, there will be some small vibration precursors, and then a large accidental collapse will occur. and society have caused great harm. However, if we can monitor these microseismic signals in time, the hazards and chances of accidents will be greatly reduced, and even early warning to a certain extent can minimize the loss...
