Seismic Data Power Station Communication System Based on UWB Technology

Abstract

The invention discloses a seismic data power station communication system based on ultra-wideband technology, which is characterized in that the communication system is set between seismic data power stations, and the seismic data power station is provided with two sets of ultra-wideband signal transmitters and ultra-wideband signal receivers, two sets of transmitters and receivers set up in each power station are used for communication with two adjacent power stations and for wireless communication between seismic data power stations. form a ring topology. The present invention provides a seismic data power station communication system based on ultra-wideband technology, which supplements the existing wired communication mode. The seismic data power station adopts a wired connection under normal working conditions. When the wired connection between adjacent seismic data power stations When the cable is damaged, the UWB wireless communication system is enabled to ensure the continuous transmission of data and provide a supplementary data connection method.

Description

technical field [0001] The invention relates to the communication field of seismic data power stations, in particular to a communication system for seismic data power stations based on ultra-wideband technology. Background technique [0002] UWB (UltraWideBand) technology, also called ultra-wideband technology. It is a technology that realizes transmission at a rate of 100Mbps to 1Gbps on a relatively large bandwidth. According to Shannon's theory, the capacity of a wireless channel is directly proportional to the channel bandwidth it occupies, and UWB can achieve a high data rate because it occupies a large bandwidth. According to the definition of UWB technology by the US FCC, a system with a relative bandwidth greater than 0.2 or a bandwidth exceeding 500MHz can be regarded as a UWB system, and the 3.1-10.6GHz frequency band is allocated as the frequency band available for the UWB system. In this frequency band, the transmission of UWB equipment The power needs to be be...

AI Technical Summary

Problems solved by technology

[0005] 1. In the process of receiving seismic wave data in the existing seismic data power station, once problems such as cable damage occur, the data received by the power station will become incomplete, and useful data cannot be extracted from it, or the received data can affect judgment

[0006] 2. The maintenance work of the damaged line is also very cumbersome, and the nodes after the breakpoint need to be checked, which consumes manpower and material resources
