Abstract
Description
Technical Field
[0001] This application relates to the field of detector embedding technology, and more specifically, to a seismic detector and detector string embedding quality testing equipment and method. Background Technology
[0002] In seismic exploration, geophones are used to receive seismic waves and transmit the acquired seismic signals to seismic exploration instruments. The working condition of the geophone directly affects the effectiveness and fidelity of seismic exploration data collection. Abnormal results in technical indicators such as DC resistance, impedance, sensitivity, damping, and distortion of the geophone will affect the quality of seismic signal reception. In addition, factors such as burial quality, including burial angle and pattern placement quality, also affect data quality. Technical indicator tests can be performed periodically using a geophone tester, and geophones or geophone strings with unqualified test results can be replaced to ensure data quality. However, effective monitoring of burial quality factors, including burial angle and pattern placement quality, has not been achieved.
[0003] Regarding the burial angle, most wired instruments currently use the system's built-in tilt test, which involves sending pulse signals and comparing the feedback signals from each detector string with an established detector standard model, outputting a test report as a percentage or generating corresponding data files. However, for nodal instruments, due to considerations of nodal unit power consumption and cost, they mostly lack tilt testing functionality or have incomplete testing capabilities. This prevents them from monitoring the burial angle of detectors or detector strings, promptly identifying and rectifying detectors with abnormal burial angles during data acquisition, and also hinders the ability to mark seismic traces with abnormal burial angle test results during data processing for later reference.
[0004] Regarding the placement of detector strings, the current correct approach in construction is to have workers hang the detectors on the placement frame or directly measure the distance between the strings using a flexible measuring tape. Some international projects even use flexible ropes to bind the distance between the strings between workers, which improves the placement quality of the detector strings. However, in practice, placement is limited by the operator's skill level, sense of responsibility, surface topography, and tolerances of measuring tools. Neither wired instruments nor nodal instruments can provide an objective evaluation, and the quality of the detector strings continues to affect the construction efficiency and quality of seismic exploration.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0029] In related technologies, a seismic detector is generally divided into a detector receiving section (i.e., the detector body that can receive signals) and node unit devices that process information. Existing seismic detectors include integrated detectors that combine the detector body and node unit devices, and separate detectors that separate the detector body and node unit devices and connect them by wire. Therefore, different methods are used adaptively depending on the type of detector when detecting angles.
[0030] Example 1 The first aspect of this application provides a seismic detector and a device for detecting the quality of detector string burial, the device comprising: The system comprises a combined measurement module and an operation control module. The operation control module is used to locate the working position of the detection device and control the combined measurement module. Based on the detector string arrangement pattern specified in the construction requirements, the operation control module calculates the combined measurement module and indicates the target positions where the detectors need to be buried. The detector string arrangement pattern is planned before construction, such as an apex shape, a triangle shape, or other shapes. Each detector has a target position in the pattern, allowing individual detectors to be buried in their target positions so that after all detectors (i.e., the detector string) are buried, they form the planned pattern, thus meeting the seismic detection requirements.
[0031] Specifically, the combined measurement module includes: a laser ranging module 5, a laser indicating module 6, a first tilt sensor 10, and a mechanical rotating platform 13.
[0032] The laser ranging module 5 is used to measure the distance from the combined measuring module to the ground.
[0033] The laser ranging module 5 is a device or component capable of measuring distance using laser technology. For example, a phase-type laser ranging module determines distance by measuring the phase difference between the laser beam traveling back and forth along the measuring line, offering advantages such as high measurement accuracy and fast response speed. During operation, the optical ranging module 5 can measure the distance from itself to the ground, i.e., the distance from the combined measuring module to the ground, preparing for the subsequent placement of the detector in the target location by the combined measuring module.
[0034] The laser indicating module 6 is used to emit a laser beam onto the ground to indicate the target location. The laser indicating module 6 contains a laser emitting unit that can emit a laser beam onto the ground according to the instructions of the laser control module 7, thereby indicating the target location.
[0035] The first tilt sensor 10 is used to measure the tilt angle of the combined measuring module and adjust the angle of the combined measuring module according to the tilt angle. When working, the first tilt sensor 10 can detect the tilt angle of the combined measuring module. When measuring the distance from the combined measuring module to the ground using the laser ranging module 5, the laser beam emitted by the laser ranging module 5 needs to be perpendicular to the ground to ensure accurate distance measurement. Therefore, the first tilt sensor 10 is needed to measure the tilt angle of the combined measuring module and adjust it in time when the combined measuring module tilts to ensure that the laser beam emitted by the laser ranging module 5 is perpendicular to the ground.
[0036] The mechanical rotating platform 13 is used to adjust the angle of the laser indicating module 6. When the laser control module 7 issues a command to the laser indicating module 6, there may be a target position located at an angle that the laser emitted by the laser indicating module 6 cannot reach. In this case, the mechanical rotating platform 13 can be rotated to adjust the angle at which the laser indicating module 6 can emit laser light, ensuring that the laser indicating module 6 can provide indication.
[0037] The operation control module includes: at least one laser control module 7, at least one first positioning module 8, and a display module; The first positioning module 8 is used to locate the working position of the detection device. When determining the working position of the detection device, the target position where the detector needs to be buried can be compared to obtain the distance from the detection device to the target position.
[0038] The laser control module 7 is used to control the laser indicator module 6 to make an indication based on the working position of the detection device and the distance from the combined measurement module to the ground.
[0039] Specifically, during operation, the detection device is inserted into a location within the area where the detector string needs to be placed. Then, the first positioning module 8 is activated to obtain the specific position of the detection device. The distance between the detection device and the target positions where each detector needs to be placed is calculated by comparing their positions. Taking a specific target position as an example, the distance between the target position and the detection device is calculated as 'b'. Then, the laser ranging module 5 is activated to detect the distance from the combined measuring module to the ground, i.e., the distance from the laser ranging module 5 to the ground, obtaining the distance to the ground as 'a'. This yields the horizontal distance 'b' from the detection device to the target position and the distance 'a' from the laser indicating module 6 (which needs to provide indication) to the ground. These two distances, 'a' and 'b', are perpendicular to each other and can form a right triangle with the straight-line distance from the laser indicating module 6 to the target position (e.g., 'c'). Using trigonometric functions, given the sides 'a' and 'b', 'c' and the corresponding angle can be obtained. After obtaining the distance c and the corresponding angle, the laser control module 7 sends a command to the laser indicating module 6, which then emits a laser beam onto the ground based on the distance c and the corresponding angle, thereby indicating the target location where the detector needs to be buried. This achieves the positioning of the detector's burial location.
[0040] The display module is used to display data from the laser control module 7, the first positioning module 8, and the combined measurement module. The display module can show the working status and data of each component, facilitating operation by construction personnel.
[0041] Furthermore, the laser pointing module 6 also includes an optical element beam splitter. The optical element beam splitter is used to split the laser beam from the laser pointing module 6, allowing the laser pointing module 6 to simultaneously indicate multiple target positions. This allows multiple target positions to be indicated in a single direction (the direction in which the laser pointing module 6 can illuminate at once). This enables the simultaneous placement of multiple detectors during construction, improving construction efficiency. Moreover, because multiple target positions are obtained at once, errors can be further reduced compared to obtaining indications one by one.
[0042] Furthermore, the detection device also includes a laser rangefinder, positioned on the same horizontal plane as the laser ranging module 5. The laser rangefinder is used to more accurately measure the distance from the laser ranging module 5 to the ground. Since the laser rangefinder and the laser ranging module 5 are on the same horizontal plane, the distance from the laser ranging module 5 to the ground can be measured, enabling a secondary measurement. This verifies the measurement accuracy of the laser ranging module 5. If there is a significant difference between the measurement data from the laser rangefinder and the laser ranging module 5, the operator needs to conduct further checks to see if the laser ranging module 5 is malfunctioning or experiencing other faults. This further ensures the accuracy of the positioning.
[0043] Furthermore, the detection device also includes a data transmission module, which receives remote control commands and sends the commands to the laser control module 7. The data transmission module can be integrated into the laser control module 7, and is essentially an existing data transmission chip and signal transmission component. This data transmission module serves as an extension of the laser control module 7, allowing construction personnel to operate it remotely. This means that one person can simultaneously install the detector and operate the detection device, eliminating the need for back-and-forth movement and reducing construction difficulty.
[0044] Furthermore, the detection device further includes a loading module for mounting the combined measurement module. The detection device also includes a main housing for mounting the loading module and inserting it into the ground. The loading module and the main housing can fix the combined measurement module on the ground while simultaneously maintaining a certain distance between the combined measurement module and the ground, thereby creating the necessary measurement conditions.
[0045] Furthermore, the loading module includes: four identical loading housings 3 arranged in a strip shape, or an integral circular platform.
[0046] Specifically, in one optional embodiment, the loading module is an integral circular platform. The lower surface of the circular platform is connected to one end of the main housing. Multiple combined measurement modules are equidistantly arranged along the circumference of the lower surface of the circular platform, and the laser control module 7, the first positioning module 8, and the display module are located at the center of the upper surface of the circular platform.
[0047] Compared to dispersed load-bearing modules, the overall circular platform design provides a more stable foundation, reducing swaying in complex terrain or during operation, thus ensuring the stability and measurement accuracy of the detection device. Multiple combined measurement modules equidistantly arranged along the circumference of the lower surface of the circular platform ensure uniform spatial distribution, avoiding mutual interference and facilitating comprehensive measurement and indication of the surrounding area.
[0048] In one optional embodiment, the loading module comprises four identical, strip-shaped loading housings 3. The detection device further includes four identical support rods 4. Each of the four loading housings 3 is hinged to one end of the main housing, and the four loading housings 3 are equidistantly distributed around the circumference of the main housing. Each of the four support rods 4 is hinged to the outside of the main housing. A groove is formed on the lower surface of each loading housing 3, and each of the four grooves corresponds one-to-one with one of the four support rods 4. One end of each support rod 4 is slidably fitted into the groove, achieving a support effect that keeps the four loading housings 3 perpendicular to the main housing. A combined measurement module is provided on the lower surface of each loading housing 3. The laser control module 7, the first positioning module 8, and the display module are located on the upper surface of the main housing.
[0049] Both the housing 3 and the support rod 4 can rotate around their connection point with the main housing. The recessed groove ensures that the support rod 4 will not detach from the housing 3 during rotation. This design allows the housing 3 and support rod 4 to rotate and fit snugly against the main housing when not in use, reducing the overall size of the device and facilitating carrying and storage. This compact storage method significantly saves space and improves the device's portability. By storing the housing 3 and support rod 4, collisions or damage during transportation or storage can be avoided, enhancing the device's durability and lifespan. Simultaneously, the recessed design ensures that the support rod 4 will not detach from the housing 3 during rotation, further enhancing storage stability and safety. When needed, simply unfold and secure the housing 3 and support rod 4 from the main housing for quick operation. This rapid deployment and storage capability improves device efficiency and reduces preparation time. Furthermore, since the housing 3 and support rod 4 can rotate and adjust independently, maintenance and component replacement are easier, reducing maintenance costs and time.
[0050] Furthermore, the main housing includes a first housing 1 and a second housing 2. The first housing 1 has a cavity, and the second housing 2 is slidably fitted into the cavity of the first housing 1, allowing the second housing 2 to extend and retract into the interior of the first housing 1. The cargo module is fitted to the end of the second housing 2 away from the first housing 1.
[0051] By allowing the second housing 2 to be retractably fitted inside the first housing 1, the entire detection device can be more compact when not in use, making it easier to carry and transport. When needed, the second housing 2 can be pulled out from the first housing 1, expanding the device's working range and improving its flexibility. Although the main housing is designed as a retractable structure, the stability of the entire detection device during operation can be ensured by adjusting the extension length of the second housing 2 and the stability structure (such as the support rod 4), thereby guaranteeing measurement accuracy. Compared to a fixed-size detection device, this retractable design may be more cost-effective in manufacturing and transportation because it can adapt to different application requirements by adjusting the size without sacrificing functionality.
[0052] Furthermore, the detection device also includes a first power supply module 9, which is disposed inside the second housing 2, and is used to supply power to the combined measurement module and the operation control module.
[0053] In field seismic exploration, power supply is often limited by the environment, such as distance from the power grid or inclement weather. The first power supply module 9 is usually a rechargeable battery or portable power source, which has high portability and durability, meeting the needs of field operations and enhancing the device's adaptability to the field. By placing the power supply module inside the second housing 2, space can be effectively utilized, reducing the complexity and interference of external wiring, making the entire detection device more compact and neat.
[0054] Furthermore, the detection device also includes a base support structure for supporting the first housing 1. The base support structure provides stable support, ensuring the detection device remains stable even in complex terrain conditions, such as soft ground where direct insertion of the first housing 1 could easily cause tilting. It also prevents swaying or tilting caused by uneven ground or wind, thus ensuring the accuracy and reliability of the detection. Specifically, the base support structure can be a tripod, quadruped, or a platform with adjustable legs.
[0055] Furthermore, the lower end of the first housing 1 is tapered. This tapered shape makes it easier to insert the first housing 1 into the soil, reducing resistance and friction during insertion and improving construction efficiency. After insertion into the soil, the tapered structure forms a more stable supporting foundation, preventing the detection device from shifting or tipping over due to wind, vibration, or other factors during field operations, thus ensuring the accuracy and reliability of the detection results.
[0056] Furthermore, the outer side of the first housing 1 is provided with a scale, and the scale value is the distance between the scale position on the first housing 1 and the distance between the combined measuring module and the ground in the direction perpendicular to the combined measuring module.
[0057] The scale values provide construction workers with a direct reference for the distance between the combined measuring module and the ground. This is especially useful when the laser ranging module 5 is unavailable or requires calibration. Workers can use these values for initial positioning and measurement, improving efficiency and accuracy. When the laser ranging module 5 is operational, its measured distance can be compared with the scale values on the outside of the first housing 1 to verify its accuracy and stability. Significant differences may indicate that the laser ranging module 5 needs calibration or replacement. In case of a malfunction or unavailability of the laser ranging module 5, the scale on the outside of the first housing 1 serves as an emergency backup. Workers can rely on these values for subsequent operations, ensuring continuity and efficiency. The presence of these scale values allows workers to flexibly choose whether to use the laser ranging module 5 or rely on the scale values for positioning, based on actual construction needs and terrain conditions, thus improving the flexibility and adaptability of the construction process.
[0058] Furthermore, the outer surface of the detection device is coated with a waterproof layer. This waterproof coating effectively prevents moisture from penetrating into the device, avoiding short circuits, corrosion, and other malfunctions in electronic components due to moisture, thereby extending the device's lifespan. During seismic exploration, the detection device may need to be placed in various complex surface environments, including damp and muddy ground. The waterproof coating allows the device to operate normally in these harsh environments, enhancing its environmental adaptability. Due to the presence of the waterproof coating, the failure rate caused by moisture intrusion is significantly reduced, decreasing the frequency of repairs and equipment replacements, thus lowering maintenance costs.
[0059] Example 2 Based on the same inventive concept, this application discloses an angle detection device, which is used in conjunction with any of the seismic exploration detectors and detector string embedding quality detection devices described in the first aspect.
[0060] The angle detection device includes: a main controller, a signal generator, a signal processing module, a second positioning module, a power supply module, and a detector connector.
[0061] The main controller is electrically connected to the signal generator, the signal processing module, the second positioning module, the second power supply module, and the detector connector, respectively.
[0062] When the detector is configured with a separate detector body and node unit device, the angle detection device is assembled at the node connector of the node unit device. In this configuration, only the detector body needs to be buried, while the node unit device is placed on the ground, but not in the same location as the detector body. Since the detector body needs to be buried underground, the angle detection device is integrated with the node unit device; that is, the angle detection device and the node unit device are assembled together. Therefore, modules such as the signal generator and the signal processing module are needed for indirect detection.
[0063] Specifically, the main controller is used to control the various modules of the angle detection device. The main controller is the core control unit of the entire angle detection device, ensuring that each module can work collaboratively according to predetermined programs and instructions to complete the task of detecting the quality of the geophones and geophone strings in seismic exploration.
[0064] The signal generator is used to send test signals to the detector. During testing, the signal generator sends a standard test signal to the detector, and the detector sends back a feedback signal when it receives the test signal.
[0065] The detector connector is used to receive the feedback signal from the detector. After receiving the feedback signal from the detector, the detector connector will transmit the feedback signal to the signal processing module.
[0066] The signal processing module processes the feedback signal received by the detector connector to determine the detector's angle tilt. When the signal processing module receives the feedback signal from the detector connector, it compares the feedback signal band with a standard signal band (ideally, a signal obtained from the standard signal). It also uses a preset data model and a user-defined threshold value. If the comparison result exceeds the threshold value, it determines that the detector's embedding angle is tilted beyond acceptable limits, thus indirectly detecting the detector's embedding angle.
[0067] The second positioning module is used to locate the position of the angle detection device. The second positioning module can locate the angle detection device, that is, the detector string assembled with the angle detection device. Simultaneously, it can provide time synchronization to the main controller, ensuring the consistency of all acquired seismic exploration data in time. It can also systematically store and manage the monitoring data of the detectors and detector strings, facilitating subsequent data traceability and retrieval.
[0068] The second power supply module is used to power the angle detection device. In field seismic exploration, power supply is often limited by the environment, such as distance from the power grid or inclement weather. The second power supply module is typically a rechargeable battery or a portable power source, offering high portability and durability, meeting the needs of field operations, and enhancing the device's adaptability to the field.
[0069] Furthermore, the angle detection device also includes: a second tilt sensor; The second tilt sensor is electrically connected to the main controller; When the detector is an integrated unit consisting of the detector body and the node unit device, the angle detection device is mounted on the housing of the node unit device. With the angle detection device and the node unit device connected together (the node unit device is exposed above ground, which does not affect the use of the angle detection device), it is equivalent to the angle detection device being connected to the detector body. The angle of the detector body can be directly detected. Therefore, the angle of the detector can be detected by using the second tilt sensor to detect the angle of the angle detection device, thereby detecting the angle of the detector.
[0070] Furthermore, the angle detection device also includes: a storage unit and a communication module; The storage unit is used to store the detector angle information detected by the angle detection device. The communication module is used to send the detector angle information detected by the angle detection device to the detection system.
[0071] The storage unit stores the detector angles measured by the angle detection device, ensuring the reliability and durability of the test data. Even in the event of a power outage or other unforeseen circumstances during testing, the tested data will not be lost, providing a solid foundation for subsequent data analysis and processing. The communication module enables the angle detection device to transmit the measured detector angles to the detection system (an existing detector management system, not described in detail here) in real time. This real-time data transmission capability allows testing personnel to instantly obtain detector status information, promptly identify and address potential problems, and improve testing efficiency and accuracy. The communication module also enables remote monitoring of the detection system. This means that testing personnel can remotely monitor the detector status without being physically present on-site, significantly reducing labor and time costs. Furthermore, this facilitates detector management in large-scale seismic exploration operations.
[0072] Example 3 Based on the same inventive concept, embodiments of this application disclose a method for placing a seismic detector. A third aspect of this application provides a method for placing a seismic detector, applied to any of the seismic exploration detectors and detector string burial quality testing devices described in the first aspect, and any of the angle testing devices described in the second aspect. The method includes: Step S11: The target location where the geophone needs to be buried is indicated by the geophone and the geophone string burial quality detection device.
[0073] The detection device is placed in the area where the detector needs to be placed. Then, the laser ranging module 5 is activated to obtain the vertical distance from the combined measuring module to the ground. The first positioning module 8 is activated to obtain the specific position of the detection device, and then the horizontal distance between the detection device and the target position is compared with the target position where the detector needs to be buried. Then, the laser control module 7 calculates the position of the laser beam emitted by the laser indicating module 6 based on the vertical distance from the combined measuring module to the ground and the horizontal distance between the detection device and the target position. Finally, the laser control module 7 controls the laser indicating module 6 to emit the laser beam, indicating the target position where the detector needs to be buried.
[0074] Step S21: Embed the detector in the target location.
[0075] Based on the target location indicated by the laser pointing module 6, the ground is excavated and the detector is buried underground.
[0076] Step S31: The embedding angle of the detector is detected by an angle detection device.
[0077] The angle detection device is fixed to the node unit of the detector. If the detector is a separate unit, the signal generator is activated to send a test signal to the detector body. After receiving the test signal, the detector body sends a feedback signal. After the detector connector of the angle detection device receives the feedback signal, it compares the feedback signal band with the standard signal band to obtain the angle of the detector body and determine whether the angle of the detector body is qualified (whether it is tilted). If it is an integrated unit, the angle of the detector can be directly obtained through the second tilt sensor, and the angle of the detector body can be determined to be qualified.
[0078] Step S41: Adjust the angle of the detector according to the angle detection result.
[0079] Adjust the angle of the detector if it is not up to standard (tilted) so that the detector is no longer tilted.
