Multi-method starting device for collecting seismic data

Abstract

The invention relates to a multi-method starting device for collecting seismic data. The invention aims to solve the problem of the prior art that a starting method is single so that the starting is difficult when the seismic data is collected; the key points of the technical scheme are as follows: a muti-method starting device for collecting seismic data comprises an input interface, an output interface and a signal starting module; the signal starting module comprises a starting method selection circuit, a short-circuit and circuit-breakage starting circuit, a buzzer piece starting circuit and a blasting device conversion circuit; input ends of the signal starting module are all electrically connected with the input interface; the output ends of the short-circuit and circuit-breakage starting circuit, the buzzer piece starting circuit and the blasting device conversion circuit are respectively connected with the output interface electrically through the starting method selection circuit; and the control end of the starting method selection circuit is connected with a plurality of toggle switches. According to the multi-method starting device for collecting seismic data, corresponding starting methods for collecting seismic data can be adopted under different hypocenters, the starting is accurate, an effect of starting a trigger signal is good, and the applicability is wide.

Description

technical field [0001] The invention relates to a starting device for data acquisition in the technical field of geophysical exploration, in particular to a multi-mode starting device for seismic data acquisition. Background technique [0002] In the past two decades, the work of energy conservation has been placed in a very high position, and the mining of underground resources is required not to waste as much as possible. Therefore, with the gradual increase in the requirements for the detection of geological structures, seismic instruments, signal processing methods and technical means have been developed. Great progress has been made, but the starting device used in seismic instrument data acquisition is relatively simple, and not much research has been done. When seismic instruments are used for detection on different occasions, the method of generating the seismic source should be carried out according to different geological structures. There are different vibration m...
