In addition, the communication mode is easily limited by complex terrain and areas, and the real-time performance of communication cannot be guaranteed, so that the communication between the seismic exploration site and the camp cannot be carried out efficiently.
Based on the above problem, an embodiment of the present application provides a data transmission device, as shown in fig. 1, which may include: the first data conversion interface 11, the first data transmission terminal 12, the second data transmission terminal 13, and the second data conversion interface 14 are described below, and the four components of the data transmission device are described correspondingly.
1) And the first data conversion interface 11 is connected with the seismic instrument and the first data transmission end and is used for converting the received data from the seismic instrument into data conforming to the transmission protocol of the first data transmission end and converting the received data from the first data transmission end into data conforming to the transmission protocol of the seismic instrument.
Because the data format, the data transmission protocol, and the like recognizable by the seismic instrument and the first data transmission end are different, the data to be transmitted in the seismic instrument may be subjected to data processing through the first data conversion interface 11, and the data processing manner may include, but is not limited to, at least one of the following: and the data is subjected to de-coding, recompression and coding, and the processed data is converted into data conforming to the transmission protocol of the first data transmission terminal 12, wherein the transmission protocol may be a network transmission protocol of TCP/IP. The first data conversion interface 11 can automatically recognize different data formats, and perform de-coding, re-compression, and transmission protocol conversion on data according to different modes.
Considering that real-time bidirectional data interaction is required between the seismic instrument and the target terminal to ensure real-time transmission and feedback of the seismic instrument in the seismic exploration field operation, the first data conversion interface 11 may also receive data from the first data transmission terminal 12 and convert the data transmitted by the first data transmission terminal 12 into data conforming to the transmission protocol of the seismic instrument.
Further, the first data conversion interface 11 may be configured with functions of phase-locked synchronization, high-speed ethernet bidirectional communication, and the like, wherein the frequency is stable in radio transmission due to the phase-locked synchronization; ethernet with a rate of 100Mb/s or more is called high-speed ethernet, which can provide bidirectional broadband communication and can flexibly upgrade bandwidth according to the demand of users for bandwidth. Therefore, the integrity of seismic data can be realized, and the transmission precision of high-speed wireless data is guaranteed.
2) The first data transmission terminal 12 is used for data interaction with the second data transmission terminal through radio electromagnetic wave signals.
Considering that the seismic instrument needs to transmit the acquired seismic data to the target terminal, the target terminal also needs to analyze the acquired seismic data and transmit an analysis result to the seismic instrument to guide the seismic instrument to perform further related operations. Therefore, the data transmission between the first data transmission terminal 12 and the second data transmission terminal 13 can be set as bidirectional data interaction. Further, a point-to-point dedicated data link may be provided between the first data transmission end 12 and the second data transmission end 13, and the point-to-point dedicated data link may operate on a single frequency channel in each direction using a time division duplex synchronization mode.

3) And the monitor 23 is connected with the seismic instrument and is used for monitoring the seismic exploration field of the seismic instrument within a preset range and transmitting the monitoring data in the monitor to the target terminal through the data transmission equipment.

When data interaction is performed between the master bridge end 43 and the slave bridge end 44, a mode of combining the mimo technology and the ofdm modulation technology may be adopted to achieve stability and reliability of non-line-of-sight long-distance wireless data transmission. In the data transmission process, multiple sending and multiple receiving are realized through multiple antennas, so that signals are synchronously transmitted through the multiple antennas after being subjected to multiple cutting, parallel data streams can be simultaneously transmitted, the fading of a channel can be obviously overcome, the error rate is reduced, the reliability of data transmission is improved, the transmission distance can be improved, and the antenna receiving range is enlarged.

The camp is resident with a person for supervising the first party and processing the seismic data for a long time, can process the seismic data in real time and feed back the processing result to the vehicle end of the seismic instrument. The seismic instrument vehicle end can perform the next operation according to the feedback processing result, so that the real-time quality monitoring can be performed on the seismic exploration field. Furthermore, the problem that real-time communication between the seismic instrument and the camp cannot be guaranteed due to the fact that effective transmission distance is shortened due to complex terrains such as hills, ravines and the like is solved.
