Seismic sensor array device and data collecting method thereof

Abstract

The invention relates to a seismic sensor array device and a data collecting method. The device comprises seismic sensors, a collecting card and a computer; by rolling and advancing of a pedrail, the seismic sensors are arranged on the pedrail, thus forming a seismic sensor array; the corresponding seismic sensor array on contact part of the pedrail and a probing surface receives the contact surface seismic wave signal, converts the vibration signal into an electric signal, and subsequently transmits the signal to the computer or a seismic recorder for recording in a cabled way by the collecting card and a sliding connector, or wirelessly transmits the signal to the computer or the seismic recorder for recording by a wireless communication device; the seismic sensor array advances by rolling, alternately contacts the probing surface and realizes quick measurement. By the arrangement of sensor touchdown shoes, the sensor and the probing surface are more closely coupled. The device can adapt to the detection on complex ground surfaces and severe condition area and can be also applicable to the detection on moon surface, building foundation surface or other solids.

Description

technical field [0001] The invention relates to a seismic sensor array device and a data acquisition method thereof, in particular to a device for real-time data acquisition using a continuously movable land seismic sensor array (Continuous Land Streamer) and a data acquisition method for the device. Background technique [0002] Seismic exploration and acoustic non-destructive testing use elastic waves as geophysical methods for test signals. The test signals can be elastic waves (seismic waves) emitted by artificially excited or naturally excited signal sources (seismic sources). The signals pass through the underground medium and are reflected , refraction and other propagation methods reach the receiving sensor array, the sensor (detector) converts the elastic wave carrying the target information into an electrical signal and records it by a seismic instrument or a digital signal collector, and then through signal data processing and analysis, determine the Detects the g...
