地震资源勘探的无线数据传输

Wireless data transmission for seismic resource exploration

针对地震勘探现场环境复杂多变,利用传统有线或单一无线技术传输数据存在可靠性低、成本高、效率低的问题,通过对现有无线技术进行分析,提出一种基于4G蜂窝网络和WiFi网络的混合型无线数据传输方案,通过TCP Vegas和队列管理预防并解除拥塞状况。测试结果表明,提出的混合型无线数据传输方案在地震勘探系统中运行可靠稳定,数据传输速率高,可吸收短时间内的大量数据流并预防拥塞的发生,为野外地震勘探过程提供技术支持,具有一定的应用前景。

In view of the complicated and variable environment of seismic exploration field,using traditional wired or single wireless technology to transmit data has the problems of low reliability,high cost and low efficiency.By analyzing the existing wireless technology,a kind of hybrid wireless data transmission scheme based on 4 G cellular network and WiFi network was proposed.The solution prevents and relieves congestion through TCP Vegas and queue management.The test results show that the proposed hybrid wireless data transmission scheme operates reliably and steadily in the seismic exploration system,has high speed of data transmission.It can absorb large amounts of data flow in a short time and prevent congestion,provides technical support for the field seismic exploration process and has certain application prospect.
