Description

Technical Field

[0001] This utility model relates to the field of seismic exploration instrument technology, specifically to an improved lightweight two-dimensional seismic exploration instrument connection device. Background Technology

[0002] The Geode-DZ distributed seismic acquisition system is a seismic data acquisition system suitable for small-scale, high-precision exploration. Its distributed, modular, and lightweight characteristics make it applicable to most seismic geological exploration scenarios. The equipment mainly includes: ① Network Interface Unit (NIU), which handles the interface control function between the controller (PC) and the ground cross station (LTU); ② Cross station (LTU), whose main function is to connect line-to-line or line-to-acquisition station (DZ), connected to the network interface unit (NIU) via a data transmission line (SCX). The cross station (LTU) does not have data acquisition channels; it only performs data transmission; ③ Acquisition station (DZ), the most important part of the distributed seismic system. A single acquisition station includes 8 acquisition channels, with 16-pin interfaces at both ends, managing 4 channels respectively; ④ Data transmission line (SCX), connecting the network interface unit and the cross station; ⑤ DZ cable (DX), integrating data transmission and analog seismic channel data lines. The cable includes seismic channel taps for connecting geophones, and each end has a 16-pin plug. ⑥ Power supply (DC): The Network Interface Unit (NIU), Cross-connect Unit (LTU), and Data Acquisition Station (DZ) are connected to an external 12V DC power supply. ⑦ Network cable and USB cable: used to connect the Network Interface Unit (NIU) and the controller (computer PC). ⑧ Controller (computer PC) and data acquisition software.

[0003] However, in practical use, the Geode-DZ distributed seismic acquisition system for 2D seismic exploration presents several challenges, including complex instrument connections, high energy consumption, heavy overall equipment, cumbersome equipment handling and relocation, and low production efficiency. The main reason for these problems is that the Geode-DZ distributed seismic acquisition system is primarily designed for small-scale, high-density 3D seismic exploration. It features distributed, modular, and lightweight characteristics, making it suitable for small-scale research projects in universities and research institutions. However, in most actual production units, long-profile 2D seismic exploration constitutes the vast majority of production work. 2D seismic exploration involves a single long survey line, and the acquisition station (DZ) and DZ line (DX) are sufficient to meet the acquisition requirements. The network interface unit (NIU) and cross-station (LTU) are somewhat redundant as control and data transmission systems. The Network Interface Unit (NIU) weighs approximately 5.0 kg, the Cross Station Unit (LTU) weighs approximately 2.0 kg, and the two matching power supplies (DC) weigh approximately 5.0 kg together. Including the matching network cable, USB cable, and data transmission cable (SCX), the total weight is approximately 15.0 kg. If 2D seismic exploration is carried out using traditional equipment connection methods, there are many equipment components, complex wiring, and the process of transporting and transferring survey lines is cumbersome. Therefore, there is an urgent need to improve the design of a lightweight instrument connection device based on the Geode-DZ distributed seismic acquisition system for 2D seismic exploration, which can fully utilize its distributed, modular, and lightweight advantages while effectively improving production efficiency. Utility Model Content

[0006] PC computer, connect the PC computer to the DZ data acquisition station;

[0007] The DX line is used to set up DZ acquisition stations and DX lines on the survey line and connect them to seismic detectors. Power is turned on the equipment to start production. The DZ acquisition station is directly connected via a network port. The data acquisition software in the PC computer is used as the main control system to transmit acquisition commands directly to the DZ acquisition station via the network port, and at the same time, the signals acquired by the DZ acquisition station are received via the network port.

[0008] Preferably, each DZ acquisition station includes 8 acquisition channels, with 16-hole interfaces at both ends, managing 4 channels respectively.

[0009] Preferably, the DX cable integrates data transmission and analog seismic trace data lines, and includes seismic trace taps for connecting detectors, with 16-pin plugs at each end.

[0010] Preferably, a connecting cable is provided between the PC computer and the DZ acquisition station, with one end being an 8-contact network port RJ45 connector and the other end being a 16-pin aviation cable connector, connecting the PC computer and the DZ acquisition station and responsible for signal transmission.

[0011] Preferably, the 8-contact network connector of the connecting cable is connected to the 16-pin aviation cable plug using an 8-core network cable.

[0012] Preferably, the 16-pin aviation cable plug is compatible with the 16-hole interface of the DZ acquisition station, wherein the R and S pins are responsible for command transmission, and the M and N pins are responsible for data reception.

[0013] The present invention adopts the above technical solution, which can bring the following beneficial effects:

[0014] 1. This improved lightweight 2D seismic exploration instrument connection device, without changing the equipment's technical parameters and original production process, uses a single connecting cable to replace the Network Interface Unit (NIU) and Cross Station (LTU) as the data transmission connection device. This effectively reduces the overall weight of the equipment and the number of system modules, making the overall system more portable while maintaining the advantages of distributed, modular, and lightweight design. This makes the Geode-DZ distributed seismic acquisition system more suitable for long-profile 2D seismic exploration in the field.

[0015] 2. This improved lightweight two-dimensional seismic exploration instrument connection device reduces the overall weight of the equipment and the number of module and cable connection steps, which greatly saves time and reduces the workload of line inspection. At the same time, the reduction of the power supply (DC) reduces the energy consumption of the entire system equipment, thus reducing carbon emissions and protecting the environment.

The cable plug is compatible with the 16-pin interface of the DZ acquisition station. The R and S pins are responsible for command transmission, and the M and N pins are responsible for data reception.

[0021] Working principle: When in use, connect directly to the DZ data acquisition station via a network port. Open the data acquisition software on the PC computer, and the software issues acquisition commands, which are directly transmitted to the DZ data acquisition station. The DZ data acquisition station enters the data receiving state. After the earthquake source is triggered, the seismic waves are converted into signals by the detector. The vibration signal is converted into an electrical signal and temporarily stored in the DZ data acquisition station.
