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 4G 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.
