Description

Technical Field

[0001] This invention relates to the field of earthquake source excitation, and more specifically to a source excitation control method, system, device, and storage medium. Background Technology

[0002] In oil and gas seismic exploration, artificial seismic events are required to generate seismic waves. Simultaneously, the seismic exploration instrument must ensure that the start time of seismic data recording is synchronized with the excitation source's activation time. Currently, the common method is to achieve this through an encoder and decoder in a source excitation synchronization control system: the encoder is connected to the instrument host, and the decoder is connected to the excitation source, communicating with each other via wired or wireless means. After receiving the detonation command from the instrument host, the encoder transmits it to the decoder. Upon receiving the detonation command, the decoder activates the excitation source according to the timing sequence, thus generating an artificial seismic event. Simultaneously with the decoder activating the excitation source, the encoder sends a time-interruption signal to the instrument host to initiate the main system's seismic data recording. After activating the excitation source, the decoder also transmits the excitation information wirelessly or via wired means to the encoder, which then sends it to the instrument host. This achieves synchronization between the instrument host's data recording system and the excitation source's activation.

[0003] In this traditional control mode, the encoder serves as the link between the instrument host and the decoder, and is crucial for achieving synchronized start-up data recording and detonation. However, limitations in the communication mechanism between the encoder and decoder prevent each encoder from achieving optimal management capabilities and minimum start-up time, thus impacting construction efficiency. Therefore, inventing a novel source synchronization control system method and device is urgently needed to improve excitation efficiency. Summary of the Invention

[0053] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to specific examples and the accompanying drawings.

[0054] It should be noted that all uses of "first" and "second" in the embodiments of the present invention are for the purpose of distinguishing two entities or parameters with the same name but different names. It is clear that "first" and "second" are only for the convenience of expression and should not be construed as limiting the embodiments of the present invention. Subsequent embodiments will not explain this in detail.

[0055] According to one aspect of the present invention, embodiments of the present invention provide a source excitation control method, such as... Figure 1 As shown, it may include the following steps:

[0056] S1, Obtain excitation parameters, wherein the excitation parameters include the excitation timing and the number of the source excitation control device to be excited;

[0057] S2, according to the excitation timing, send a start command carrying a first start time to the source excitation control device and the synchronization detection device to be excited respectively, so that the source excitation control device to be excited and the synchronization detection device are started according to the first start time respectively;

[0058] S3, receive the second start time at startup from the source excitation control device to be excited and the third start time at startup from the synchronization detection device;

[0059] S4, determine the error between the first startup time, the second startup time, and the third startup time;

[0060] S5, in response to the error between the three being within a preset range, the first startup time is used as the benchmark for data segmentation.

[0061] The solution provided by the embodiments of the present invention sends the start time to the source excitation control device and the synchronization detection device simultaneously through the control platform. After the source excitation control device and the synchronization detection device start, they send the start time of the start time to the control platform. By comparing the three GPS times, the synchronization of the entire system is ensured.

[0062] Meanwhile, by eliminating the role of the encoder in the source synchronization system, the control platform can start the excitation source without controlling the encoder. This solves the problem in traditional exploration operations where the management capability and minimum start-up time of each encoder cannot be optimized due to the communication mechanism between the encoder and decoder. It can manage and control the excitation source more effectively, achieve higher efficiency in data acquisition, and improve the accuracy of start-up synchronization and the quality of acquired data.

[0063] In some embodiments, it also includes:

[0064] If the error between two of the three is within a preset range, and the error of one exceeds the preset range, the start time of either of the two with errors within the preset range is selected as the reference for data segmentation, and a time error error is indicated for calibration.

[0065] In some embodiments, it also includes:

[0066] Receive the pulse signal generated at startup from the synchronization detection device;

[0067] Compare the pulse width and amplitude of the pulse signal with a preset value;

[0068] If both the pulse width and the amplitude are preset values, then the pulse signal is determined to be correct.

[0069] The accuracy of the third start-up time is determined based on the time when the pulse signal is received.

[0070] In some embodiments, it also includes:

[0071] It receives information such as device type, device ID, GPS coordinates, and check code from the source excitation control device to be excited.

[0072] Specifically, the control platform can connect to the synchronization detection device via a network interface (or other means) and exchange information, monitoring the connection status in real time. Simultaneously, the analog pulse signal generated after the synchronization detection device is triggered is transmitted to the control platform in real time via a wired analog acquisition channel; the control platform communicates with the source excitation control device via wired or wireless means.

[0073] Once the source excitation control device is ready, it will send the ready information via wired or wireless means according to a specific protocol. The ready information should include the source excitation control device ID, the collected coordinate information, GPS status, check code, and other information.

[0074] The control platform receives the readiness information from the source excitation control device, first checks the information to determine if it is valid and meets the excitation requirements; for source excitation control device information that meets the requirements, it automatically determines the excitation sequence and excitation time according to the time-distance rules set in the control software.

[0075] The control platform sends a command containing startup information to all source excitation control devices and synchronization detection devices via wired or wireless means. The startup information includes the ID of the source excitation control device to be started, the startup time, the check code, and other information.

[0076] After receiving the command information from the control platform, all source excitation control devices must decode and parse it to determine whether they are the controller to be excited. If not, the information is automatically discarded; if so, the agreed GPS excitation start time must be parsed. After receiving the command information from the control platform, the synchronization detection device decodes and parses the command information, and then excites according to the agreed GPS excitation start time in the command information.

[0077] Both the source excitation control device and the synchronization detection device must be started strictly according to the agreed GPS excitation time. At the same time, the internal hardware circuit needs to generate a pulse signal. The pulse signal triggers and records the GPS time. The synchronization detection device also needs to output this pulse signal to the control platform at the same time.

[0078] It should be noted that the control platform can determine whether the synchronization detection device's time is correct by comparing the time of the received pulse signal with the start time sent by the synchronization detection device. Since the time of the received pulse signal is based on the control platform's time, if the time of the received pulse signal is inconsistent with the start time sent by the synchronization detection device, it indicates that the internal clock of the control platform or the synchronization detection device is malfunctioning.

[0079] After the source excitation controller and synchronous detection device start excitation, they send excitation information to the control platform. The excitation information includes equipment type, equipment ID, GPS time of start, GPS coordinates, check code, and other information.

[0080] The control platform compares the start time it sends with the start times of the source excitation control device and the synchronization detection device. If the times match, the subsequent data is segmented based on that time. At the same time, the amplitude and pulse width of the pulse signal output by the synchronization detection device are detected to ensure that the control platform records and excites synchronously.

[0081] It should be noted that under normal conditions, the amplitude and pulse width of the pulse signal received by the control platform are consistent with the preset parameters. If they are inconsistent with the preset parameters, it indicates that the pulse signal is abnormal. At this time, it is impossible to determine whether the third start time sent by the synchronization detection device is correct.

[0082] The control platform compares the signal amplitudes of the three GPS times and the pulse signal start time. If the error is within the specified range, the next task is performed. If the error is outside the specified range, an error message is displayed, and the operation needs to be stopped for inspection. If one of the three times differs significantly, while the other two times are within the allowable error range, then one of these two times is used as the data segmentation time. After data segmentation, an error message will also be displayed indicating that the error of the three times exceeds the specified range, and the operation needs to be stopped for inspection.

[0083] It should be noted that if two times are within the allowable error range, one of the two times can be temporarily used as the time base for data splitting, and then a time calibration check can be performed. If both times are normal, the data from this source excitation can be retained. If they are not normal, calibration can still be performed, thus retaining the data from this source excitation. Therefore, as long as two of the three times are within the allowable error range, the data from this source excitation can be retained.

[0084] In some embodiments, it also includes:

[0085] The timing of the control platform, the source excitation control device, and the synchronization detection device is adjusted based on GPS time.

[0086] Specifically, the control platform can use GPS for time synchronization and calibrate its time to keep it consistent with GPS time; the synchronization detection device needs to use GPS time synchronization function, calibrate its internal clock to keep it consistent with GPS time, and generate a simulated pulse signal and the GPS time corresponding to the triggering time after being triggered; the source excitation control device needs to use GPS for time synchronization and calibrate its internal clock to keep it consistent with GPS time.

[0087] The following section uses six source excitation control devices, numbered 1, 2, 3, 4, 5, and 6, as an example to explain in detail the scheme proposed in this application.

[0088] During normal seismic exploration operations, the construction route arrangement for each source excitation control device is complex and different. Therefore, at a certain time, only one source excitation control device may be in the waiting state for excitation, or multiple source excitation control devices may be in the waiting state for excitation at the same time.

[0089] like Figure 2 As shown, the control platform connects to the synchronization detection device via a network interface (or other means) and exchanges information to obtain information about its standby status. It also communicates with the source excitation control device via wired or wireless means.

[0090] GPS is used to provide timing for the control platform, synchronization detection device, and source excitation control device.

[0091] The control platform uses GPS for time synchronization. After the time synchronization is stable, it calibrates the internal time of the host to keep it consistent with the GPS time, displays a successful time synchronization status, and the host is in a working state. The synchronization detection device uses GPS for time synchronization. After the time synchronization is stable, it calibrates the internal clock to keep it consistent with the GPS time, displays a successful time synchronization status, and is in a working state.

[0092] Once the source excitation control device is ready, it will send the ready information via wired or wireless means according to a specific protocol. The ready information should include the source excitation control device ID, the collected coordinate information, GPS status, check code, and other information.

[0093] Upon receiving the readiness information from the source excitation control device, the control platform first checks the information to determine its validity and eligibility for excitation. Source excitation control devices meeting the excitation conditions are then displayed in the excitation list as devices awaiting excitation. For example, source excitation control devices with IDs 1 and 3 are in the triggering state, source excitation control device ID 4 is in the excitation state, and source excitation control devices with IDs 2, 5, and 6 are in the awaiting excitation state. The excitation order for the awaiting excitation control devices can be manually selected, or it can be automatically set using a time-distance rule algorithm configured in the control platform.

[0094] Suppose that the control platform wants to activate the source excitation control device with ID 5, it needs to send information including the device ID 5 and the activation time (e.g., 12345678) to all source excitation control devices and synchronization detection devices via wired or wireless means.

[0095] After receiving the command information from the control platform, all source excitation control devices must decode and parse it, and determine whether they are the controllers to be excited. Since the information indicates that the source excitation control device with ID 5 should be activated, source excitation control devices with IDs 1, 2, 3, 4, and 6 will automatically discard the information after receiving and checking it. However, the source excitation control device with ID 5 and the synchronization detection device, after receiving the command information from the control platform, decode and parse it. If the information passes the check, they will compare the agreed-upon start excitation GPS time with their current GPS time. If the comparison time is earlier or significantly later, the excitation will be abandoned; if the comparison time is within the set range, the excitation will proceed according to the agreed-upon GPS time.

[0096] Both the source excitation control device and the synchronization detection device must be started strictly according to the agreed GPS excitation time. At the same time, the internal hardware circuit needs to generate a pulse signal. The pulse signal triggers and records the GPS time. The synchronization detection device also needs to output this pulse signal to the control platform at the same time to detect its amplitude and pulse width, so as to ensure that the control platform records and excitation are synchronized. Then, the control platform can use the time of receiving the pulse signal to check the start time sent by the synchronization detection device.

[0097] After the source excitation control device and the synchronization detection device start the excitation, they send the excitation information to the control platform. The excitation information includes the device type, device ID, GPS time of start, GPS coordinates, check code and other information.

[0098] The control platform compares its own startup time with the startup times of the source excitation control device and the synchronization detection device. For example, if the startup time sent by the control platform is 1650362850.000000s, the startup time returned by the source excitation control device is 1650362850.000015s, and the startup time returned by the synchronization detection device is 1650362850.000010s, assuming the allowable error range is 20us, then the time results of the comparison of the three are consistent, and the data will be segmented according to the startup time sent by the control platform.

[0099] After comparing the signal amplitudes of the three GPS times and the pulse signal start time, the control platform proceeds to the next task if the error is within the specified range. If one of the three times differs significantly while the other two times are within the allowable error range, one of these two times is used as the data segmentation time. After data segmentation, an error message will be displayed indicating that the error of the three times exceeds the specified range, and the operation needs to be stopped for inspection.

[0100] The proposed solution uses a GPS device to provide time synchronization for the three components. After the source excitation control device is ready, it sends information to the control platform. The control platform determines the excitation sequence based on the set parameters and simultaneously sends the start time to both the source excitation control device and the synchronization detection device. After the source excitation control device and the synchronization detection device start, they send the GPS time of the start time to the control platform. At the same time, the synchronization detection device also generates a pulse signal and outputs it to the control platform through an analog path. The software compares the three GPS times and analyzes the start time of the pulse signal to ensure the synchronization of the entire system.

[0101] The proposed solution eliminates the encoder found in current control methods and reduces the number of steps in the data exchange process, thus shortening communication latency. Its applicability is enhanced, making it perfectly suitable for any operating area, including plains, deserts, and Gobi. It also significantly improves the system's management and control capabilities, supports more flexible communication modes, and substantially increases the production efficiency of field construction.
