Cable-free seismometer long-distance quality monitoring and control system and outdoor quality monitoring and control method

Abstract

The invention relates to a cable-free seismometer long-distance quality monitoring and control system and an outdoor quality monitoring and control method. The cable-free seismometer long-distance quality monitoring and control system is composed of a Beidou satellite, a master control center, a collecting station, a long-distance quality monitoring and control method and a Beidou user machine module communication process management method. Compared with the prior art, cable-free storage-type seismometer long-distance quality monitoring and control are achieved, and the outdoor work flexibility and the outdoor work reliability of a cable-free storage-type seismometer are improved. The characteristics that the Beidou satellite communication technology is wide in coverage scope, high in instantaneity and high in reliability are adopted, stable monitoring and control over the fieldwork quality of the collecting station in field arrangement are achieved, and the monitoring and control scope of the system is not limited by the track pitch. The collecting station is remotely controlled to selectively conduct collecting work, the power dissipation of the system is reduced, and storage space is saved. Arrangement position information of the collecting station is monitored, class reports are recorded, constructors are reasonably scheduled according to information monitoring and controlling results of the collecting station, and the construction efficiency of the outdoor exploration operation of the cable-free storage-type seismometer is greatly improved.

Description

Technical field: [0001] The invention relates to a remote monitoring system and a method for a cableless seismograph for seismic exploration, in particular to a remote monitoring system and a monitoring method for realizing the field work quality of a cableless storage seismograph by using Beidou satellite communication technology. Background technique [0002] At present, seismic exploration of oil and gas resources is mainly based on cabled seismic data acquisition systems. The 428XL of France's Sercel company, the ARIES launched by Canada's ARAM company and the Scorpion cabled telemetry seismic data acquisition system of ION company of the United States are the mainstream seismic data acquisition systems at home and abroad. However, with the increase in demand for the number of seismic acquisition channels in oil and gas resource exploration, the number and weight of cables in seismic data acquisition systems have increased sharply, making it difficult to arrange and wiring in ...

AI Technical Summary

Problems solved by technology

However, in the deep reflection and refraction detection operations of seismic exploration with a trace spacing greater than 1km, due to the limited signal coverage of the base station, there are certain limitations in the work of remote monitoring seismic acquisition stations, and the data transmission delay time is long, especially for Simultaneous control or data reception of a large number of collection stations will cause information congestion, low reliability, and difficulty in ensuring construction efficiency
