Full-digitalization system for collecting and processing engineering dual-source surface wave exploration data

Abstract

The invention discloses a full-digitalization system for collecting and processing engineering dual-source surface wave exploration data, comprising a host, digitalized low-frequency wave detectors, a cable interface unit, an operation control unit, a digital cable, a seismic focus trigger line assembly and a storage battery cable assembly, wherein a data link is composed of the digitalized low-frequency wave detectors; the data link is connected with the input end of the host via the digital cable and the cable interface unit; the host and the operation control unit are connected; the seismic focus trigger line assembly is connected with an artificial source and the host; the storage battery cable assembly is connected with a storage battery, the host and the data link; the digitalized low-frequency wave detectors are used for collecting a surface wave signal of the artificial source and a surface wave signal of a natural source and carrying out analog-to-digital conversion on the collected signals; and the processed signals are transmitted to the host by the digital cable via the cable interface unit and are processed by the host. According to the full-digitalization system, thesurface wave data of the artificial source can be collected and processed, and the microseisms data of the natural source can be collected and processed. The same system can be used for exploring therange from the ground to a position which is 300m below the ground, and even can be used for exploring with the depth below 1000m.

Description

technical field [0001] The invention relates to early warning and rescue technical products of major production accidents in the field of public safety, in particular to a full digital engineering dual-source surface wave exploration data acquisition and processing system. Background technique [0002] The surface wave instrument used in the past uses a detector as a vibration pickup, which can only collect surface wave signals from artificial sources, and cannot be used to collect surface wave signals from natural sources, and the detection depth is only 20m to 40m below the surface. The ground wave instrument is used to collect natural source surface wave signals supplemented by low frequency pendulum, but it cannot be used to collect artificial source surface wave signals, and the detection depth is less than 100m. At present, there is no exploration data acquisition and processing system in the market that can collect both artificial source surface wave signals and natur...
