This invention discloses a seismic acquisition decision-making system and method. The system includes a data retrieval subsystem, a receiving control subsystem, and an excitation control subsystem. The data retrieval subsystem includes node acquisition units and a data retrieval terminal. The node acquisition units periodically acquire seismic signals and node status data, and the data retrieval terminal wirelessly retrieves and uploads the status data of each node. The receiving control subsystem acquires the SPS file of the construction area and the status data of each node, determines the arrangement of the preset nodes, and sends it to the excitation control subsystem.

Description

Technical Field

[0001] This invention relates to the fields of seismic exploration equipment technology and exploration engineering technology, and in particular to a seismic acquisition and decision-making system and method. Background Technology

[0002] Seismic instruments are the core equipment in seismic exploration, responsible for acquiring and recording seismic data in the field. Seismic instruments are mainly divided into two types: wired systems and wireless (node) systems.

[0003] In the field of petroleum seismic exploration, nodal acquisition equipment is gradually becoming the mainstream equipment for seismic exploration. Unlike traditional geophysical acquisition equipment that uses wired connections, nodal acquisition equipment uses local data storage, satellite synchronization and time synchronization technologies. Compared with traditional wired instruments, this wireless type of node does not require cable connection and theoretically has no cable capacity limitations, which facilitates large-scale and flexible deployment. It is widely used in seismic acquisition projects under various surface conditions such as mountains, urban areas, deserts and plains.

[0004] However, the biggest drawback of node acquisition equipment is its blind acquisition method, which leads to insufficient quality control of node data. In current node-based seismic acquisition operations, node status QC data is typically collected one-to-one from all deployed arrays using a handheld device based on the retrieval task order. This data is then compiled and sent to the indoor interpretation team. The interpretation team manually assesses whether the node arrays are complete and usable before issuing an excitation task order to the excitation team. The excitation team then performs the excitation according to the task order and submits an excitation report to the interpretation team. The interpretation team determines whether any arrays can be retrieved based on the excitation report. If retrievable arrays exist, a retrieval task order is issued to the retrieval team for execution. Therefore, inconsistencies frequently arise between the recording system and the excitation system during construction, resulting in excitation starting before arrays are ready or arrays being retrieved before excitation is complete, leading to incomplete or missing seismic data. Summary of the Invention

[0005] This invention provides a seismic acquisition decision system and method to achieve collaborative decision-making in seismic acquisition.

The excitation control subsystem uses the arrangement status to determine whether shot points can be excitationd and generates an excitation report after excitation. The receiving control subsystem then determines whether the node arrangement has been retrieved. This improves the decision-making efficiency of seismic acquisition, enables collaborative intelligent decision-making in seismic acquisition, and ensures the effectiveness of shot point excitation and the integrity of seismic data.

[0024] Example 1

[0025] Figure 1 This is a schematic diagram of the structure of a seismic acquisition and decision-making system provided in Embodiment 1 of the present invention. Figure 1 As shown, the system includes: a data recovery subsystem 1, a receiving control subsystem 2, and an excitation control subsystem 3. The data recovery subsystem 1 includes a node acquisition unit 11 and a data recovery terminal 12. Each node acquisition unit 11 is set at a preset inspection point in the construction area.

[0026] The data recovery subsystem 1 is used to periodically collect seismic signals and node status data through the node acquisition unit 11, preprocess the seismic signals and store them locally, and wirelessly recover and upload the status data of each node through the data recovery terminal 12. The receiving control subsystem 2 is used to acquire Shell Processing Support Format (SPS) files and node status data of the construction area, determine the arrangement status of the preset nodes based on the SPS files and node status data, and send them to the excitation control system. The excitation control subsystem 3 is used to determine the excitation points from the preset shot points based on the arrangement status and SPS files, execute the excitation, generate an excitation report and transmit it to the receiving control subsystem 2. The receiving control subsystem 2 is used to determine the recovery arrangement nodes and recovery tasks based on the excitation report.

[0027] In this embodiment, the node acquisition unit 11 can be understood as a wireless seismic signal acquisition device. The node acquisition unit 11 includes a main controller, a sensor module, a signal acquisition module, a Bluetooth transmission module, a Global Navigation Satellite System (GNSS) module, and a storage module. The data retrieval terminal 12 can be understood as a device that receives data wirelessly. The construction area can be understood as the area where seismic exploration is conducted. Node status data can be understood as data used to characterize the working status of the node acquisition unit 11 and the environmental conditions of its surroundings, such as acquisition status, detector resistance value, station tilt angle, GNSS status, ambient noise, available battery capacity, and available space.

[0028] It is understandable that an SPS file is used to store relevant data from 3D seismic exploration. This data may include checkpoint data related to the location of the node acquisition unit 11 (each checkpoint location requires the deployment of a node acquisition unit 11 for seismic signal recording), shot point data related to the shot point location (each shot point location requires well shot or source excitation to generate seismic signals), and relationship data between checkpoints and shot points (multiple checkpoints need to be deployed to record data when a shot point is excited, thus ensuring that data can be acquired; this relationship is mainly used to analyze subsequent retrievable arrangements).

[0029] In this embodiment, the preset node arrangement can be understood as a group of node acquisition units 11 that are planned in advance according to their position and order. A construction area may include multiple preset node arrangements; for example, all node acquisition units 11 located on a horizontal or vertical line can be used as the preset node arrangement. The arrangement status can be understood as a status value used to characterize whether the arrangement is working properly; for example, 0 can represent not working properly, and 1 can represent working properly. The preset shot point can be understood as a pre-set shot point location for generating seismic signals. The expungable shot point can be understood as a shot point that can currently generate seismic signals. The excitation report can be understood as data related to the shot point and node acquisition unit 11 after excitation. The retrieval arrangement node can be understood as a node arrangement that has completed signal acquisition and can be manually retrieved. The retrieval task can be understood as the task of retrieving the equipment contained in the retrieval arrangement node after the completion of field construction.

[0030] Specifically, the data recovery subsystem 1 can include two parts: a node acquisition unit 11 and a data recovery terminal 12, both located at each preset checkpoint. The node acquisition unit 11 is used to acquire seismic signals at that checkpoint, convert analog signals into digital signals, and store them on a local storage medium. It can also monitor its own operational status and periodically transmit current node status data wirelessly. For example, the node status data of the node acquisition unit 11 may include acquisition status, detector resistance value, station tilt angle, GNSS status, ambient noise, available battery capacity, and available space. The data recovery terminal 12 can receive the node status data and upload it to a corresponding storage space, such as a cloud server 4. The construction area can be divided according to the maximum receiving range of the data recovery terminal 12, with multiple data recovery terminals 12 set up within the construction area to cover the acquisition tasks of all node acquisition units 11. Alternatively, the data recovery terminal 12 can be mounted on a mobile device, and the movement route of the mobile device can be planned to cover the acquisition tasks of all node acquisition units 11 in the construction area.

[0031] For example, due to geophysical exploration requirements, the node acquisition unit 11 needs to operate continuously in the field for more than 30 days. Therefore, the node acquisition unit 11 needs to minimize power consumption. Simultaneously, to ensure the node unit status recovery rate, the data transmission distance should be as long as possible. Thus, the node acquisition unit 11 can use a low-power BLE 5.0 dedicated Bluetooth chip, nRF52832, to periodically send signals via Bluetooth broadcast mode, or transmit node status data wirelessly via wireless network or local area network. The status data recovery terminal 12 uses a Bluetooth receiver module with a power amplifier (PA) function, achieving an air transmission distance of over 150 meters. The node acquisition unit 11 can periodically send data using Bluetooth broadcast mode, and the recovery terminal receives and parses the broadcast data information, reducing communication connection time during status data recovery. The status data recovery terminal 12 can be installed on various devices such as drones, vehicles, or handheld devices to achieve rapid status data recovery, ensuring that recovery can be completed even when the vehicle is traveling at high speed.

[0032] Specifically, the receiving control subsystem 2 can obtain Shell processing-supported SPS files and node status data of the construction area through methods such as downloading from the cloud. Based on the SPS files and node status data, it performs quality inspection on each node acquisition unit 11 to determine the node status of each node acquisition unit 11. It uses the SPS files to determine the node acquisition units 11 included in each preset node arrangement, and uses the status of each node acquisition unit 11 to determine the arrangement status of the preset node arrangement and send it to the excitation control system. The receiving control subsystem 2 and the excitation control subsystem 3 can share information through a physical connection.

[0033] Specifically, the SPS file also records the association between each preset shot point and node arrangement. For example, preset shot point 1 is associated with node arrangement 2 and node arrangement 3, meaning that the seismic signal generated by preset shot point 1 is acquired through node arrangement 2 and node arrangement 3. The excitation control subsystem 3 can comprehensively determine whether a preset shot point can be excited based on whether the arrangement status is normal. If the arrangement status of all node arrangements associated with the preset shot point is normal, the preset shot point is determined to be an exciteable shot point. The excitation control subsystem 3 can perform excitation on the exciteable shot point. After successful excitation, an excitation report is generated and transmitted to the receiving control subsystem 2 to assist the receiving control subsystem 2 in subsequent judgments.

[0034] Specifically, since each node acquisition unit 11 can be responsible for acquiring data from multiple preset firing points, the receiving control subsystem 2 can determine the firing reports of all preset firing points in each node acquisition unit 11 to determine whether all preset firing points have been fired, thereby determining whether the node acquisition unit 11 has been used up. Since the retrieval task is performed according to the node arrangement, the receiving control subsystem 2 can further determine whether the node arrangement can be retrieved by checking whether each node acquisition unit 11 in each preset node arrangement has been used up. The nodes that can be retrieved are designated as retrieval arrangement nodes, and a retrieval task is generated to notify relevant personnel to retrieve the retrieval arrangement nodes.

[0035] The technical solution of this invention is applied to an earthquake acquisition and decision-making system. The system includes: a data retrieval subsystem, a receiving control subsystem, and an excitation control subsystem. The data retrieval subsystem includes node acquisition units and a data retrieval terminal. Each node acquisition unit is set at a preset checkpoint location in the construction area. The data retrieval subsystem is used to periodically acquire earthquake signals and node status data through the node acquisition units, preprocess the earthquake signals and store them locally, and wirelessly retrieve and upload the node status data through the data retrieval terminal. The receiving control subsystem is used to acquire Shell Processing Supported Format (SPS) files and node status data in the construction area, determine the arrangement status of preset nodes based on the SPS files and node status data, and send it to the excitation control system. The excitation control subsystem is used to determine the retrieval points from preset shot points based on the arrangement status and the SPS files, execute the excitation, generate an excitation report, and transmit it to the receiving control subsystem. The receiving control subsystem is used to determine the retrieval arrangement nodes and retrieval tasks based on the excitation report. The data retrieval subsystem rapidly retrieves node status data, and the receiving control subsystem performs quality control on node arrangement based on this data to determine the arrangement status. The excitation control subsystem uses the arrangement status to determine whether shot points can be excitationd and generates an excitation report after excitation. The receiving control subsystem then determines whether the node arrangement has been retrieved. This improves the decision-making efficiency of seismic acquisition, enables collaborative intelligent decision-making in seismic acquisition, and ensures the effectiveness of shot point excitation and the integrity of seismic data.

[0036] By way of example, the specific components of the seismic acquisition decision system of the present invention are illustrated by a specific example. Figure 2 This is a structural example diagram of an earthquake acquisition and decision-making system provided in Embodiment 1 of the present invention. Figure 2 As shown, the system includes: a data recycling subsystem 1, a receiving control subsystem 2, an excitation control subsystem 3, and a cloud server. The data recycling subsystem 1 includes a node acquisition unit 11 and a data recycling terminal 12. The receiving control subsystem 2 includes a data download unit 21, a node quality control unit 22, and an arrangement management unit 23. The excitation control subsystem includes an excitation judgment unit 31, an excitation driving unit 32, and a report generation unit 33.

[0037] Furthermore, the receiving control subsystem 2 includes:

[0038] Data download unit 21 is used to acquire the SPS file of the construction area and the status data of each node;

[0039] The node quality control unit 22 is used to determine the node working status of each node acquisition unit 11 based on the SPS file and the status data of each node.

[0040] The arrangement management unit 23 is used to determine the arrangement status of the preset node arrangement based on the SPS file and the node working status.

[0041] In this embodiment, the node working status can be understood as a status indicator used to characterize whether each node acquisition unit 11 can work normally, for example, 0 indicates that it cannot work normally, and 1 indicates that it can work normally.

[0042] Specifically, the receiving control subsystem 2 can access the cloud through the data download unit 21 to download and parse node status data and SPS files. The node quality control unit 22, based on the SPS files, calculates the average value of various indicators for all node acquisition units 11 within a block, since multiple node acquisition units 11 can be divided into blocks. This average value, along with preset judgment criteria, determines the node operating status of each node acquisition unit 11. The arrangement management unit 23 first identifies all node acquisition units 11 belonging to a preset node arrangement based on the SPS files. Then, by comprehensively judging the node operating status of all node acquisition units 11 belonging to the same preset node arrangement, the arrangement status of that preset node arrangement is determined.

[0043] The node status data includes: node acquisition status, GNSS status, detector resistance value, station tilt angle, ambient noise, available battery capacity, and available space. Correspondingly, the node quality control unit 22 is specifically used for:

[0044] Obtain the preset decision standard information for the construction work area; for each node acquisition unit 11, determine the detector quality inspection result of the node acquisition unit 11 based on the resistance values ​​of all detectors in the work area block to which the node acquisition unit 11 belongs, the detector resistance value of the node acquisition unit 11, and the preset decision standard information; determine the environmental noise quality inspection result of the node acquisition unit 11 based on the environmental noise and the preset decision standard information; determine the node working status of the node acquisition unit 11 based on the detector quality inspection result, the environmental noise quality inspection result, the node acquisition status, the GNSS status, the available space, the available battery capacity, the station tilt angle, and the preset decision standard information.

[0045] In this embodiment, node acquisition status can be understood as a state characterizing whether node acquisition unit 11 is acquiring seismic signals normally. Detector resistance value can be understood as a value characterizing the resistance of the detector. Station tilt angle can be understood as a value characterizing the tilt angle of node acquisition unit 11 underground. Environmental noise can be understood as the noise level of the environment in which node acquisition unit 11 is located. Available battery capacity can be understood as a value reflecting the remaining power of node acquisition unit 11. Available space can be understood as a value reflecting the remaining capacity in the storage medium of node acquisition unit 11. Work area blocks can be understood as the result of dividing the construction work area into multiple blocks. Preset decision standard information can be understood as standard data used to determine whether node acquisition unit 11 is functioning normally. Environmental noise quality inspection results can be understood as a value characterizing the environmental noise quality inspection status, and can be represented by 0 and 1. Detector quality inspection results can be understood as a value characterizing whether the detector is functioning normally, and can be represented by 0 and 1. GNSS status can be understood as a value reflecting the current operating status and signal quality of the Global Navigation Satellite System.

[0046] Specifically, the node quality control unit 22 can acquire preset decision standard information for the construction area. For each node acquisition unit 11, it calculates the average resistance of the block within the work area based on the resistance values ​​of all detectors within that block. The quality control unit then comprehensively determines the detector quality inspection result of the node acquisition unit 11 by combining the average resistance, the detector resistance values ​​of the node acquisition unit 11, and the resistance temperature coefficient and acceptable resistance threshold coefficient in the preset decision standard information. The node quality control unit 22 can also calculate the average noise level based on all environmental noise within the work area. Finally, it comprehensively determines the environmental noise quality inspection result of the node acquisition unit 11 by combining the environmental noise of each node acquisition unit 11, the average noise level, and the environmental noise threshold coefficient for different work areas in the preset decision standard information (wherein, the environmental noise threshold coefficient varies depending on the location of the different construction areas, such as urban areas, rural areas, and roads). The node quality control unit 22 can comprehensively determine the node working status of the node acquisition unit 11 based on the detector quality inspection results, environmental noise quality inspection results, node acquisition status, GNSS status, available space, available battery capacity, station tilt angle and preset decision criteria information.

[0047] For example, for the current node acquisition unit 11Node i The calculation methods for each attribute are as follows:

[0048]

[0049] Among them, Ret iRes This is the quality inspection result of the detector, R i(t) represents the detector resistance value at the current acquisition time t, K t It is the current time detector resistance temperature coefficient, K. res N represents the threshold coefficient for the acceptable range of detector resistance value, and N represents the number of all node acquisition units 11 within the work area block to which the current node acquisition unit 11 belongs.

[0050]

[0051] Among them, Ret iNoise This is the result of the environmental noise quality inspection, N i The current node's sampling unit 11 contains the environmental noise sampling point values, where n is the total number of environmental noise sampling points within its work area, and Std is the sampling point value. noise To avoid affecting the environmental noise standard value of seismic data, K noise This refers to the environmental noise threshold coefficient in different work areas.

[0052] Ret iNode =Ret iRes +Ret iNoise +Ret iAcq +(V iGrad ≤Std Grad *K Grad )+Ret iGNSS +(V iFreeMem ≤Ste FreeMem *K FreeMem )+(V iBat ≤Std Bat *K Bat )

[0053] Among them, Ret iNode This is the current node operating status of node acquisition unit 11, Ret ires The above calculations represent the detector quality inspection results, Ret iNoise The above calculations represent the environmental noise quality inspection results. iAcq It refers to the node acquisition status in the recovered node status data, V. iGrad It is the tilt value of the recovered node acquisition unit 11, Std Grad To preset the tilt standard value of node acquisition unit 11 in the decision-making standard information, K Grad It is the tilt threshold coefficient of node acquisition unit 11 in the preset decision-making standard information, Ret iGNSS It is the GNSS status in the node status data, V iFreeMem It is the available space value of the recovered node acquisition unit 11, Std FreeMem For the available spatial standard value of node acquisition unit 11 in the preset decision standard information, K FreeMemIt is the available space threshold coefficient of node acquisition unit 11 in the preset decision-making standard information. V iBat The available battery capacity of the recovered node acquisition unit 11, Std Bat For the standard value of available battery capacity of node acquisition unit 11 in the preset decision-making standard information, K Bat It is the threshold coefficient of available battery capacity in the preset decision-making standard information.

[0054] In this embodiment, the arrangement management unit 23 is specifically used for:

[0055] Based on the SPS file, determine the preset node arrangement list; poll the preset node arrangement in the preset node arrangement list to determine the target node working status and target node status data of the target node acquisition unit 11 belonging to the preset node arrangement; determine the arrangement status of the preset node arrangement based on the working status of each target node and the recovery completion status in the status data of each target node.

[0056] In this embodiment, the preset node arrangement list can be understood as a list containing all preset node arrangements under the construction area. The target node acquisition unit 11 can be understood as all node acquisition units 11 belonging to the same preset node arrangement; its corresponding node working state is the target node working state, and its corresponding node state data is the target node state data. The recovery completion status can be understood as a characterization of whether the target node state data transmitted by the target node acquisition unit 11 has been recovered; for example, 0 can represent not received, and 1 can represent received.

[0057] Specifically, the arrangement management unit 23 can determine a preset node arrangement list based on the SPS file, poll the preset node arrangements in the preset node arrangement list, determine all target node acquisition units 11 belonging to the currently polled preset node arrangement, and obtain their corresponding target node working status and target node status data. The arrangement management unit 23 can comprehensively determine the arrangement status of the preset node arrangement based on the working status of each target node and the collection completion status in the target node status data.

[0058] For example, the permutation state can be calculated using the following formula:

[0059]

[0060] Among them, Line i It is the current preset node arrangement state, U iNode Ret indicates the completion status of the target node acquisition unit 11, indicating whether the recycling is complete. iNoiseThis refers to the target node working status of the target node acquisition unit 11 calculated above. If all target nodes are in normal working status and the recovery completion status of each target acquisition unit is "recovered", then the arrangement status of the preset node arrangement is normal, which can be represented by 1; otherwise, it is 0 to indicate abnormal.

[0061] Furthermore, based on the above embodiments, the activation control subsystem 3 includes:

[0062] The excitation judgment unit 31 is used to determine the excitation point from the preset shot points according to the arrangement state and SPS file;

[0063] The excitation drive unit 32 is used to excite the exciteable shot point and determine the excitation result;

[0064] The report generation unit 33 is used to generate an excitation report based on the excitation results.

[0065] Specifically, since a single shot point can correspond to multiple node arrangements for detecting its generated seismic signals, the excitation control subsystem 3, through the excitation judgment unit 31, determines all node arrangements associated with a preset shot point based on the SPS file. It then determines whether the preset shot point is an excitationable shot point by checking if the arrangement status of all associated node arrangements is normal. If all are normal, it is considered an excitationable shot point; otherwise, the next preset shot point is evaluated. The excitation drive unit 32 can trigger the excitation of excitationable shot points by issuing excitation tasks to them, obtaining the excitation result indicating whether the excitation was successful. The report generation unit 33 can generate an excitation report based on the excitation result.

[0066] Specifically, the triggering judgment unit 31 is used for:

[0067] Based on the relational subfiles in the SPS file, determine the arrangement of target nodes associated with the preset shot points; based on the arrangement of each target node, determine the firing state of the preset shot points; and designate the preset shot points with the firing state of being firingable as firingable shot points.

[0068] In this embodiment, the relational sub-file can be understood as a file used to record the association between preset shot points and node arrangements. The target node arrangement can be understood as the node arrangement for acquiring seismic signals generated by preset shot points. The excitation state can be understood as a state used to characterize whether the preset shot point can be excited, for example, it can be represented by 0 and 1.

[0069] Specifically, the excitation judgment unit 31 can determine the arrangement of all target nodes associated with the preset shot point based on the relational subfile in the SPS file, and determine the excitation state of the preset shot point based on the arrangement state of each target node. If all arrangement states are normal, the excitation state is excitation-capable; otherwise, the excitation state is excitation-uncapable. The excitation judgment unit 31 can use preset shot points with an excitation-capable state as excitation-capable shot points.

[0070] For example, the excitation state can be calculated using the following formula:

[0071]

[0072] Among them, Shot i This is the firing state of the current preset firing point, Line i It is the arrangement state of this node, NU iShot Indicates the current preset firing point. i Whether to use this node for sorting. If Shot i The calculation result indicates that the target node arrangement for the preset shot point is in a normal state, and therefore, it can be fired. A successful firing report is then sent to the receiving control system. The successfully fired shot point is identified by the SF6000 SF6 ... i To express.

[0073] Furthermore, the receiving control subsystem 2 is specifically used for:

[0074] Based on the firing reports of the shot points associated with each node acquisition unit 11, the node completion status of the node acquisition unit 11 is determined; based on the completion status of each node, the arrangement completion status of the preset node arrangement is determined; if the arrangement completion status is complete, the shot point node arrangement is used as the retrieval arrangement node.

[0075] In this embodiment, the node completion status can be understood as indicating whether the node acquisition unit 11 has completed exploration. The arrangement completion status can be understood as indicating whether the node arrangement has been explored.

[0076] Specifically, the receiving control subsystem 2 can determine whether all shot points acquired by each node acquisition unit 11 have been successfully activated based on the firing reports of the shot points associated with each node acquisition unit 11. If all shot points have been successfully activated, the node completion status is "exploration complete"; otherwise, the node completion status is "exploration incomplete". The receiving control subsystem 2 can also determine the completion status of a preset node arrangement based on the completion status of each node. If all node acquisition units 11 within the same preset node arrangement have a "exploration complete" status, the preset node arrangement is considered complete; otherwise, it is considered incomplete. If the arrangement completion status is complete, the receiving control subsystem 2 can use the shot point node arrangement as a retrieval arrangement node.

[0077] For example, the completion status of a node can be determined using the following formula:

[0078]

[0079] Among them, NS p It is the current node unit. p The node completion status, that is, using the current node unit Node. p Have all m gun spawn points been successfully fired and sent firing reports? (SF) i This indicates that the current firing point has been successfully fired and a firing report has been sent. SU iShot Indicates the current firing point. i Node acquisition unit 11 p use.

[0080] For example, the completed arrangement status can be determined using the following formula:

[0081]

[0082] Among them, F kLine This indicates the completion status of the current node arrangement, which can be used to determine whether the calculation result can be recycled. NU pNode This is the current node acquisition unit 11 Node. p Whether it is used by the preset node arrangement k.

[0083] Optionally, the receiving control subsystem 2 also includes a task partitioning unit, specifically used for:

[0084] Based on the SPS file and the terminal recycling attributes of the data recycling terminal 12, the construction area is divided into blocks to obtain the construction area blocks; the node acquisition units 11 are divided into blocks according to the construction area blocks to obtain the node acquisition unit 11 set belonging to each construction area block; based on the node acquisition unit 11 set, a data recycling task is generated and sent to the data recycling terminal 12 so that the data recycling terminal 12 can collect the node status data of each node acquisition unit 11 in the node acquisition unit 11 set.

[0085] In this embodiment, terminal recycling attributes can be understood as performance attributes of the data recycling terminal 12 for data recycling, such as wireless coverage range. A work area block can be understood as the result of dividing a construction work area into smaller blocks. A set of node acquisition units 11 can be understood as the collection of all node acquisition units 11 belonging to the same work area block. A data recycling task can be understood as instructing the data recycling terminal 12 to recycle the node acquisition units 11.

[0086] Specifically, the receiving control subsystem 2 can divide the construction area into blocks based on the SPS file and the terminal recycling attributes of the data recycling terminal 12, thus obtaining construction area blocks. For example, the construction area blocks can be divided based on the wireless coverage range and the number of terminals of each data recycling terminal 12. The receiving control subsystem 2 can also divide the node acquisition units 11 into blocks according to the construction area blocks, grouping node acquisition units 11 belonging to the same construction area block into a set of node acquisition units 11, thus obtaining a set of node acquisition units 11 belonging to each construction area block. Based on the set of node acquisition units 11, the receiving control subsystem 2 can generate a data recycling task and send it to the data recycling terminal 12, so that the data recycling terminal 12 can collect the node status data of each node acquisition unit 11 in the set of node acquisition units 11.

[0087] Optionally, the system also includes: cloud server 4;

[0088] Cloud server 4 is used to receive and save the status data of each node of data recycling subsystem 1 and the recycling tasks of control subsystem 2.

[0089] Specifically, cloud server 4 can receive node status data uploaded by data recycling terminal 12 in data recycling subsystem 1 and save it to the local database. It can also receive recycling task data uploaded by receiving control subsystem 2 and save the recycling task data.

[0090] The technical solution of this invention, in terms of node status data retrieval from the node acquisition unit, utilizes a wireless data retrieval terminal, enabling rapid retrieval of the node acquisition unit. After retrieval, the terminal's built-in communication module automatically uploads the retrieval status results to a cloud server. The receiving control subsystem can view and analyze the node status data in real time, solving the problems of low efficiency, high cost, and high risk associated with traditional manual data collection followed by indoor data import. Compared to wired operations, the receiving control subsystem and the excitation control subsystem can share information through a physical connection, ensuring the quality and effectiveness of the operation. The receiving control subsystem determines the validity of the arrangement based on the retrieved node status data. By sharing arrangement and excitation information between the two subsystems, it dynamically commands the excitation system to control blasting. After excitation, the excitation control subsystem generates an excitation report, which is transmitted to the receiving control subsystem. Based on the excitation report, the receiving control subsystem determines which arranged nodes can be retrieved, achieving automatic judgment in the retrieval process and ensuring the accuracy of retrieval task issuance. This achieves collaborative intelligent decision-making in seismic acquisition, ensuring the effectiveness of shot point excitation and the integrity of seismic data.

The data retrieval subsystem includes node acquisition units and data retrieval terminals. Each node acquisition unit is set at a preset checkpoint location in the construction area.

[0093] like Figure 3 As shown, the method includes:

[0094] S310: Seismic signals and node status data are collected periodically through the node acquisition unit. The seismic signals are preprocessed and stored locally. The status data of each node is collected wirelessly through the data recovery terminal and uploaded.

[0095] S320: Obtain the SPS file and node status data of the construction area through the receiving control subsystem, determine the arrangement status of the preset node arrangement based on the SPS file and node status data, and send it to the excitation control system.

[0096] S330. The excitation control subsystem determines the excitation points from the preset shot points according to the arrangement status and SPS file, executes the excitation, generates an excitation report, and transmits it to the receiving control subsystem.

[0097] S340. The receiving control subsystem determines the recycling arrangement nodes based on the excitation report.

[0098] The technical solution of this invention rapidly recovers node status data through a data recovery subsystem. Then, a receiving control subsystem performs quality control on node arrangement based on the node status data to determine the arrangement status. An excitation control subsystem determines whether shot points can be excitationd based on the arrangement status and generates an excitation report after excitation. Finally, the receiving control subsystem determines whether the node arrangement has been recovered. This improves the decision-making efficiency of seismic acquisition, realizes collaborative intelligent decision-making in seismic acquisition, and ensures the effectiveness of shot point excitation and the integrity of seismic data.
