Shallow-layer seismic prospecting system based on wireless data transmission and exploration method

Abstract

The invention relates to a shallow-layer seismic prospecting system based on wireless data transmission, comprising a shallow-layer seismic prospecting master station, a shallow-layer seismic prospecting triggering substation, and a plurality of shallow-layer seismic prospecting detection substations. The shallow-layer seismic prospecting master station comprises a data processing host and a wireless access point. The shallow-layer seismic prospecting triggering substation comprises a first wireless boundary device and a first shock sensor for sensing earthquake focus shock signal. Each shallow-layer seismic prospecting detection substation comprises a second shock sensor, a filter, a signal gain controller, an analog-to-digital converter, a processor and a second wireless boundary device.The invention is advantageous in that the anti-interference capability is stronger, and the shallow-layer seismic prospecting result can be more accurate.

Description

technical field [0001] The invention relates to the technical field of shallow seismic exploration, in particular to a shallow seismic exploration system and an exploration method based on wireless data transmission. Background technique [0002] At present, most shallow seismic prospecting instruments use cables to connect the sensors at each observation point, and transmit the seismic signals of each observation point to the central host, which performs data collection and related processing. The main inconvenience of this system is the problem of cables. In order to ensure the reliability of the cable, the cable uses a high-strength cable, and the bulky cable will lead to low efficiency of the test site layout; there are multiple connection points for the cable connection in the test site layout, and complex environmental factors in the field may It will lead to poor contact at the connection point, and most shallow seismic prospecting instruments lack the sensor connect...

The main inconvenience of the system is the cable

In order to ensure the reliability of the cable, the cable uses a high-strength cable, and the bulky cable will lead to low efficiency of the test site layout; there are multiple connection points for the cable connection in the test site layout, and complex environmental factors in the field may It will lead to poor contact at the connection point, and most shallow seismic prospecting instruments lack the sensor connection detection function, and can only judge whether the sensor connection is normal through the detection data; the layout of the detection point may sometimes need to cross some obstacles, which may affect the cable laying.
