Description

Technical Field

[0001] The present invention belongs to the technical field of seismic exploration, and in particular relates to a source control terminal and a source excitation information generation system, method, equipment and medium. Background Art

[0002] During seismic exploration, vibrators are typically used to generate seismic waves. To generate source excitation information, each seismic exploration vehicle independently generates seismic waves and communicates with the control terminal of the seismic instrument vehicle. After the control terminal receives qualified vibration performance indicator information, it generates source excitation information.

[0003] However, when using the above method to generate source excitation information, the following technical problems often occur:

[0004] First, when determining the structure of the source excitation node corresponding to each seismic exploration vehicle, a distributed node architecture that can add relay nodes was not adopted, resulting in a shorter communication distance and lower transmission efficiency, which in turn led to a weaker source excitation effect and, in turn, poorer quality of the collected source data.

[0005] Second, the excitation method of partitioned multi-node synchronous sliding was not adopted, resulting in a weak source excitation effect and a long excitation time, which in turn led to poor quality of the collected source data. Summary of the Invention

[0006] The purpose of the present invention is to provide a source control terminal and source excitation information generation system, method, equipment and medium to improve data transmission efficiency, enhance the source excitation effect, and thereby improve the quality of source data.

[0007] In order to achieve the above-mentioned purpose, the technical methods adopted by the present invention are as follows:

[0008] A seismic source excitation information generation system includes a target seismic exploration vehicle, a relay seismic exploration vehicle, and a seismic source control terminal. The target seismic exploration vehicle and the relay seismic exploration vehicle are both equipped with a MESH communication radio, an on-board terminal, and a vibrator. The MESH communication radio of the relay seismic exploration vehicle forms a MESH self-organizing network. The on-board terminal includes a GPS module and an excitation information transmission control module. The GPS modules of the on-board terminals in the target seismic exploration vehicle and the relay seismic exploration vehicle feed back position information to the seismic source control terminal in real time. The excitation information transmission control modules of the on-board terminals in the target seismic exploration vehicle and the relay seismic exploration vehicle are communicatively connected to the seismic source control terminal via the corresponding MESH communication radio and the MESH self-organizing network. The control terminals of the excitation information transmission control modules of the on-board terminals in the target seismic exploration vehicle and the relay seismic exploration vehicle are connected to the vibrators of the corresponding seismic exploration vehicles.

[0009] The source control terminal is used to receive the position feedback information of the target seismic exploration vehicle after it arrives at the shot point position, which is sent by the GPS module of the on-board terminal in the target seismic exploration vehicle, and determine the distance between the position of the target seismic exploration vehicle and the source control terminal based on the position feedback information; determine whether the distance between the shot point position of the target seismic exploration vehicle and the source control terminal exceeds the communication distance between the MESH communication radio of the target seismic exploration vehicle and the source control terminal; if it exceeds, select a seismic exploration vehicle located in the path from the source control terminal to the source node of the target seismic exploration vehicle from multiple seismic exploration vehicles as a relay seismic exploration vehicle, and the MESH communication radios corresponding to the relay seismic exploration vehicles form a MESH self-organizing network; the target seismic exploration vehicle is connected to the source node of the target seismic exploration vehicle through the MESH self-organizing network. The system sends the corresponding source excitation time to the excitation information transmission control module of the on-board terminal of the target seismic exploration vehicle; receives the source excitation preparation information sent by the excitation information transmission control module of the on-board terminal of the target seismic exploration vehicle through the MESH self-organizing network, and sends the source excitation signal of the target seismic exploration vehicle to the excitation information transmission control module of the on-board terminal of the target seismic exploration vehicle through the MESH self-organizing network, so that the excitation information transmission control module of the on-board terminal controls the corresponding vibrator to perform the source excitation operation according to the source excitation time; receives the vibration performance index information of the source excitation operation of the target seismic exploration vehicle, and determines whether the vibration performance index information meets the preset performance index condition; when the vibration performance index information meets the preset performance index condition, generates source excitation success information.

[0010] As a limitation: the source excitation information generation system also includes a relay terminal; the source control terminal also includes determining the distance between the relay seismic exploration vehicles. If the distance between the relay seismic exploration vehicles exceeds the communication distance of their corresponding MESH communication radio stations, then a relay terminal is set up between the relay seismic exploration vehicles that exceed the communication distance; determining the distance between the relay seismic exploration vehicle closest to the source control terminal and the source control terminal. If the distance between the relay seismic exploration vehicle closest to the source control terminal and the source control terminal exceeds the communication distance of its corresponding MESH communication radio stations, then the distance between the relay seismic exploration vehicle closest to the source control terminal and the source control terminal exceeds the communication distance of its corresponding MESH communication radio stations. A relay terminal is set up between the relay seismic exploration vehicle closest to the source control end and the source control end; the distance between the relay seismic exploration vehicle closest to the target seismic exploration vehicle and the target seismic exploration vehicle is determined; if the distance between the relay seismic exploration vehicle closest to the target seismic exploration vehicle and the target seismic exploration vehicle exceeds the communication distance of their corresponding MESH communication radio stations, a relay terminal is set up between the relay seismic exploration vehicle closest to the target seismic exploration vehicle and the target seismic exploration vehicle; the MESH communication radio stations and relay terminals corresponding to the relay seismic exploration vehicles form a MESH self-organizing network.

[0011] The present invention also discloses a method for generating source excitation information, comprising the following steps performed in sequence:
