Embodiment Construction

[0027] As shown in the figure, the storage type seismic signal continuous acquisition system of the present invention includes a base station 1 and a digital detector 3 that are not connected to the central station and data communication, and the base station 1 communicates with a plurality of parallel digital detectors through a data transmission interface 2 and a cable 4 The base station is connected with the digital geophone 3; the data transmission module is used between the base station and the digital geophone to transmit instructions and collect data; the base station is the control and storage center of the storage type seismic signal continuous acquisition system, which controls the data transmission interface and the digital geophone to complete the seismic data reception. And store the data in its built-in memory; the data transmission interface is used to complete the sending of instructions and the reception of collected data; the digital detector is used to complet...

Abstract

The invention relates to a storage type earthquake signal continuous collecting system aiming to solve the problems of narrow dynamic range and poor anti-interference ability in the prior seismometercollecting system and comprising a base station and digital geophones. The base station is connected with a plurality of digital geophones which are arranged in parallel through data transmission interfaces and cables; commands are transferred and data are collected between the base station and each digital geophone by adopting a data transmission module; the base station is a control and storagecenter of the storage type earthquake signal continuous collecting system and is used for controlling the data transmission interfaces and the digital geophones to finish receiving of earthquake dataand store the data into an internal memory; the data transmission interfaces are used for finishing the sending of the commands and the receiving of the collected data; and the digital geophones are used for finishing the collecting of analog signals and converting the analog signals to data, and then the data transmission interfaces thereof finish the sending of the data, therefore, the inventionhas the advantages of wide dynamic range, strong anti-interference ability, low cost and capable of supporting collection of tens of thousands of geophones for multiple years.

Description

technical field [0001] The invention relates to a seismic signal acquisition system of a seismograph, in particular to a storage type continuous seismic signal acquisition system. technical background [0002] High-precision digital seismograph is a geological exploration instrument used to record artificial or natural seismic signals, and then to find oil, gas, coal and other mineral resources based on the records of these seismic signals, and can be used to detect the internal structure of the earth, conduct engineering and geological Disaster prediction, etc. [0003] Seismic exploration method is still the main means of oil and gas exploration on land and sea, and also an important exploration method for other mineral resources, and is widely used in the study of the earth's internal structure, engineering exploration and detection, geological disaster prediction and so on. Digital seismographs used for geophysical exploration of mineral resources can be divided into th...
