Field discrete type seismic digital recording instrument

Abstract

The invention relates to a field discrete type seismic digital recording instrument. The field discrete type seismic digital recording instrument comprises a wave detector, an interface circuit, a sampling holder, an A / D converter, a CPU, a GPS module and a data memory; the wave detector is used for detecting seismic wave signals; the signal output end of the wave detector is connected with the signal input end of the interface circuit; the signal output end of the interface circuit is connected with the signal input end of the sampling holder; the signal output end of the sampling holder is connected with a signal input end of the A / D converter; the signal output end of the A / D converter is connected with the signal input end of the data memory; the clock signal input end of the data memory is connected with the signal output end of the GPS module; and the GPS module is connected with an antenna. No cables or wires exist on the field discrete type seismic digital recording instrument of the invention, and limitations caused by wire and cable connection can be eliminated, and therefore, the field discrete type seismic digital recording instrument is very convenient to use.

Description

technical field [0001] The patent of the present invention relates to the fields of exploration for oil, natural gas, coal fields, civil engineering, and foundation survey of buildings, especially a seismic monitoring instrument, specifically a field discrete seismic digital recording instrument. Due to the cable-free wireless, it completely gets rid of the shackles of the current conventional wired cable connection, and is extremely convenient to use. Background technique [0002] At present, the seismic data acquisition system is very large and complex, basically imported products, expensive, and connected by cable, which is very inconvenient to use, especially when the surface terrain is complex, the laying of cable seismic data acquisition stations is very difficult ; On the other hand, when a wired cable is damaged somewhere, the entire system will not work properly. Contents of the invention [0003] The purpose of the present invention is to address the above probl...
