Description

Technical Field

[0001] The present invention belongs to the technical field of seismic exploration, and in particular relates to a seismic exploration network differential service system, method, equipment and medium. Background Art

[0002] With the continuous advancement of exploration technology and the rapid development of high-precision, low-cost, and efficient geophysical exploration models, the scope of seismic exploration is also expanding. The expansion of seismic data acquisition operations into large-scale work areas such as mountainous areas, swamps, and urban areas has highlighted new demands for geophysical exploration equipment and technology. Due to the complex and diverse exploration terrain, especially during exploration and measurement operations in urban areas with complex building structures, the limited coverage of radio network differential positioning and the susceptibility of network differential data to interference are inevitable.

[0003] In practice, construction layout personnel require fixed measurement solution data to determine the layout location. However, due to the presence of buildings or other obstructions during construction, a fixed positioning solution cannot be obtained within a short distance from the base station, making construction layout operations impossible. If construction layout operations continue in this area, the base station must be relocated to a specific location so that the base station radio data communication covers the operation area and a stable base station positioning solution data link is achieved. Due to the limited coverage of the base station, achieving acceptable positioning accuracy for construction layout within the construction area requires frequent relocation of the base station, which wastes construction time and delays production progress. Summary of the Invention

[0004] The purpose of the present invention is to provide a seismic exploration network differential service system, method, equipment and medium to quickly establish network differential services, avoid the waste of construction time and delay in production progress caused by multiple relocations of base stations within a work area.

[0005] In order to achieve the above-mentioned purpose, the technical methods adopted by the present invention are as follows:

[0006] A seismic exploration network differential service system includes multiple base stations, geophysical surveying base station service software, a network differential cloud server, multiple mobile stations, geophysical surveying-specific software and seismic source navigation system software; the base stations are communicatively connected to the geophysical surveying base station service software, which is in communication with the network differential cloud server, and the mobile stations are communicatively connected to the network differential cloud server, the geophysical surveying-specific software and the seismic source navigation system software respectively; the geophysical surveying base station service software, the network differential cloud server, the geophysical surveying-specific software and the seismic source navigation system software are all embedded with a communication link monitoring module for real-time monitoring of the status of data communication links; the network differential cloud server presets the number of each base station and the number of each mobile station, and groups the mobile stations and corresponding base stations that use the same base station to solve high-precision positioning data into the same group and establishes a communication link.

[0007] As a limitation: the communication between the base station and the geophysical measurement base station service software, the communication between the geophysical measurement base station service software and the network differential cloud server, the communication between the mobile station and the network differential cloud server, the communication between the mobile station and the geophysical measurement software, and the communication between the mobile station and the source navigation system software all use one or more of Bluetooth, 3G / 4G / 5G public networks.

[0008] As a further limitation: The geophysical survey base station service software is based on geographic information, developed using the JAVA language with the help of the Android Studio development platform and SQLite database, and is equipped with a measurement host, electronic map and mobile communication technology to switch and receive differential data sent by different base stations, and send it to the network differential cloud server.

[0009] As a further limitation: The geophysical surveying software is based on geographic information, developed in JAVA language with the help of Android Studio development platform and SQLite database, switches and receives differential data sent by different mobile stations, and is combined with the surveying host, electronic map and mobile communication technology to perform real-time and precise positioning and layout of physical points in the field.

[0010] As a further limitation: The source navigation system software is based on geographic information, developed in JAVA language with the help of Android Studio development platform and SQLite database, switches and receives differential data sent by different mobile stations, and is equipped with source boxes, electronic maps and mobile communication technology to determine the positioning accuracy before the source point is excited. If the positioning error is not within the range allowed by the project, it is necessary to obtain the positioning information again from the mobile station and complete the source excitation while meeting the requirements of the engineering project.

[0011] A seismic exploration network differential service method includes the following steps performed in sequence:

[0012] S1. Set up base stations in the work area, preset the numbers of each base station and each rover in the network differential cloud server, group the rover and corresponding base stations that use the same base station to calculate high-precision positioning data into the same group and establish a communication link;

The communication link monitoring module embedded in the geophysical measurement base station service software monitors the data communication link status between the base station and the geophysical measurement base station service software in real time. If the geophysical measurement base station service software receives differential data abnormally, it automatically re-receives the differential data; the communication link monitoring module embedded in the network differential cloud server monitors the data communication link status between the geophysical measurement base station service software and the network differential cloud server in real time. If the network differential cloud server receives differential data abnormally, it automatically re-receives the differential data;

[0014] S3, the network differential cloud server sends the received differential data to the corresponding mobile station according to the corresponding grouping of the base station and the mobile station;

If the geophysical measurement software receives the mobile station's own positioning data abnormally, it automatically re-receives the mobile station's own positioning data. The communication link monitoring module embedded in the seismic source navigation system software monitors the status of the data communication link between the mobile station and the seismic source navigation system software in real time.
