Abstract
Description
Technical Field
[0001] The present invention belongs to the technical field of geophysical exploration, and relates to an excitation source excitation control technology based on a hybrid communication network, in particular to a multi-mode excitation method and device based on a hybrid communication network. Background Art
[0002] With the rapid development of geophysical exploration technology, high-density spatial sampling has become the key to solving the quality of seismic data and reservoir description accuracy in complex areas. After the global exploration market continues to reduce exploration and development investment, low-cost and efficient acquisition has become the goal pursued by all exploration companies. To solve this problem, technological innovation will undoubtedly be the only way to solve high-cost and inefficient operations. The main problems that need to be solved include the following two aspects: On the one hand, the source excitation control system in the traditional mode can only use a single communication network to exchange data information, and the single communication method is greatly affected by the environment.
[0003] Taking the Loess Plateau area in northern Shaanxi as an example, when using 4G / 5G mobile communication networks for communication, the signal is better near the villages, but the network signal is poor away from the villages; when using radio station communication networks, the signal is better far away from the villages, but the signal near the villages is poor.
[0004] On the other hand, in the traditional mode, only a single excitation mode of the controller can be set before starting work, and the excitation modes cannot be mixed, which greatly limits the production efficiency of field collection.
[0005] In summary, it is urgent to invent a new multi-mode excitation control method and device for seismic exploration based on a hybrid communication network, realize the integration of multiple communication networks and automatic priority determination, optimize the existing multi-mode hybrid acquisition control algorithm, realize balanced excitation through polling cycles, and provide a more efficient solution for efficient excitation control. Summary of the invention
[0006] In order to solve the above problems and deficiencies existing in the prior art, the present invention aims to provide a multi-mode excitation method and device based on a hybrid communication network, which can effectively improve the poor communication problem caused by a single communication network and the inefficiency problem caused by a single excitation mode, and greatly improve the well gun excitation efficiency.
[0007] To achieve the above purpose, the technical solution adopted by the present invention is as follows: A multi-mode excitation method based on a hybrid communication network is that in a hybrid communication network environment, a central control system determines the priority of each communication network, and the central control system automatically sets the working mode of the controller, so that controllers with different working modes can be mixed and used in the same project, and the shot point excitation is performed, wherein, The priority of each communication network is set manually or automatically; The working modes of the controller include a central control excitation mode and a time slot autonomous excitation mode. Among them, the working mode of each controller can be freely switched according to the stimulation needs.
[0008] Further, the method comprises the following steps which are performed in sequence: S1. Device connection The central control system and controller are connected to satellite timing devices respectively to ensure that the central control system time and controller time are always consistent with the satellite time; The central control system communicates with the controller based on a hybrid communication network; S2. Priority setting of communication network The priority of each communication network in the hybrid communication network is set manually, or the priority of each communication network in the hybrid communication network is determined automatically according to the accuracy of the test data of each communication network and the strength of the signal; S3. Controller working mode setting After the controller enters the working state, it automatically sends online status information to the central control system through the communication network and applies for its working mode. The central control system configures according to its application information and sends the actual working mode of the controller. When the actual working modes of all controllers are the central control excitation mode, the central control excitation mode is issued to all controllers; When the actual working mode of all controllers is the time slot autonomous excitation mode, the time slot autonomous excitation mode is issued to each controller respectively, and the start excitation time and polling cycle are set; S4. Shot point excitation After the controller working mode is set, the controller and the central control system exchange data through the hybrid communication network to realize the firing point excitation. For the central control excitation mode controller: after receiving the ready information of several gun points to be fired from the controller, the central control system places them into the sequence of gun points to be fired, calculates and selects a gun point to be fired from the sequence according to the time-distance rule, sends the gun point information and firing time of the selected gun point to be fired, and the controller receives the firing time, displays the countdown, and fires the gun point; The prepared information includes line number, stake number, controller number and shot point position coordinates; For the time slot autonomous excitation mode controller: autonomously excite the shot points according to the preset start excitation time and polling cycle, without communicating with the central control system; The shot point information includes line number, stake number, controller number, excitation mode and shot point position coordinates; S5. Statistical Analysis The central control system will update the firing information of the fired shot points received in real time, mark them as fired on the display interface, and perform statistical analysis on the firing efficiency; The firing information includes shot point information and firing time.
[0009] Furthermore, the priority setting of the communication network described in step S2 is that the central control system sends a communication network test request to the controller, and the controller automatically sends the defined test data to the central control system through each connected communication network. The central control system determines the priority of the hybrid communication network by comprehensively judging the accuracy of the received test data and the strength of the signal, wherein, The higher the accuracy of the test data of the communication network, the higher the priority; when the accuracy of the test data of each communication network is the same, the stronger the communication network signal, the higher the priority.
[0010] Furthermore, in the actual working mode of the controller described in step S3, when the actual working mode of the controller includes a central control excitation mode and a time slot autonomous excitation mode, the central control system calculates the total time as the cycle time length according to the number of controllers and the controller excitation interval time, and divides the total time into two parts, one part of the time is used as the central control excitation mode, which is used to control all controllers in the central control excitation mode; the other part of the time is used as the time slot autonomous excitation mode, which determines the start excitation time and polling period of each time slot autonomous excitation mode controller in sequence according to the numbering sequence and the excitation interval time of each time slot autonomous excitation mode controller.
[0011] Furthermore, the data interaction described in step S4 is determined by the central control system automatically decomposing the data sent from the first priority communication network; if the data sent from the first priority communication network is erroneous, the data sent from the second priority communication network is automatically decompiled, and so on.
[0012] Furthermore, if there are problems with the decoded data of each priority communication network, the data of the high-priority communication network is used as the main body, and the data information of the low-priority communication network is integrated. The principle is to replace and verify the different parts of the data information one by one to obtain the correct result.
[0013] Furthermore, the firing information in step S5 is transmitted back immediately after firing, or the firing information is added to the ready information of the next shot point and transmitted back.
[0014] Furthermore, the communication network in the hybrid communication network integrated control platform includes 4G / 5G mobile communication network, Beidou communication network, satellite communication network and radio station communication network.
[0015] The present invention also provides a multi-mode excitation device based on a hybrid communication network, comprising: Equipment connection unit: used to connect satellite timing devices and hybrid communication networks; A communication network priority setting unit: used to determine the priority of each communication network in the hybrid communication network; Controller working mode setting: used to set the controller working mode; Shot point excitation unit: used for shot point excitation; Statistical analysis unit: used for statistical analysis of excitation efficiency.
[0016] Due to the adoption of the above technical solution, the technical progress achieved by the present invention compared with the prior art is: (1) The multi-mode excitation method based on a hybrid communication network provided by the present invention greatly improves the effect of data communication by integrating multiple communication networks, and effectively solves the technical problem of poor communication in a single communication network; (2) The multi-mode excitation method based on a hybrid communication network provided by the present invention realizes a multi-mode hybrid acquisition method of the controller, performs separate control management of time blocks according to different modes, realizes balanced excitation control management through polling cycles, and realizes efficient acquisition of well and gun excitation operations; (3) The multi-mode excitation method based on the hybrid communication network provided by the present invention has strong applicability and can be applied to operating areas such as plains, deserts and Gobi; (4) The device provided by the present invention can quickly and effectively implement a multi-mode excitation method based on a hybrid communication network.

DETAILED DESCRIPTION
[0019] The present invention is further described in detail below through specific embodiments. It should be understood that the preferred embodiments described herein are only used to illustrate and understand the present invention, and are not used to limit the present invention.
[0020] Embodiment 1 A multi-mode excitation method based on a hybrid communication network In this embodiment, 9 controllers are provided, numbered 1, 2, ..., 8, 9, of which 6 controllers are in central control excitation mode, numbered 1, 2, 3, 4, 5, 6 respectively; the other 3 controllers are in time slot autonomous excitation mode, numbered 7, 8, 9; the excitation time interval is 10s; The communication networks include Beidou communication network, 4G / 5G mobile communication network, satellite communication network and radio station communication network.
[0021] This embodiment is a multi-mode excitation method based on a hybrid communication network, comprising the following steps performed in sequence: S1. Device connection The central control system is connected to the communication network and the satellite timing device. After startup, the communication network types used are preset in the application software as Beidou communication network, 4G / 5G mobile communication network, satellite communication network and radio station communication network. The central control system communicates according to the selected communication network; The central control system uses a satellite timing device for timing. After the timing is successful, the system clock is calibrated to ensure that the system time is always consistent with the satellite time. The controller is connected to the communication network and satellite timing device consistent with the central control system. After the power-on self-test is normal, the satellite time is synchronized and the system clock is calibrated to ensure that the time of the controller is consistent with that of the central control system. S2. Priority setting of communication network The central control system sends a communication network test request to the controller, and the controller automatically sends a number of defined test messages to the central control system at fixed intervals through the connected Beidou communication network, 4G / 5G mobile communication network, satellite communication network and radio communication network. The central control system determines the communication network signal strength of the Beidou communication network, 4G / 5G mobile communication network, satellite communication network and radio communication network by detecting the accuracy of the received test information and the strength of the signal; The test data accuracy of the 4G / 5G mobile communication network is the highest. The accuracy of the Beidou communication network, satellite communication network and radio station communication network is the same. The communication network signals range from strong to weak. Therefore, the central control system application software automatically determines the priority of the communication network: the first priority is the 4G / 5G mobile communication network, the second priority is the Beidou communication network, the third priority is the satellite communication network, and the fourth priority is the radio station communication network.
[0022] S3. Controller working mode setting After the controller works normally, it automatically sends online status information to the central control system through the communication network and applies for its working mode. The central control system receives the application information through the first priority communication network and sends the actual working mode and configuration parameters of the controller. The time slot is set as follows: The time slot working diagram is as follows Figure 1 As shown, the application software calculates the total time of 90s as the total time slot based on 9 controllers and the 10s excitation interval time, and divides the 90s into two parts according to the above working mode, of which 60s is the central control excitation mode time, which is used to control all controllers in the central control excitation mode; the other 30s is the time slot autonomous excitation mode time, which determines the controller start excitation time in sequence according to the number 7, 8, 9 and the time slot time set in the application software, such as the start excitation time of controller No. 7 is 1672730200, and the excitation cycle is 90s; the start excitation time of controller No. 8 is 1672730210, and the excitation cycle is 90s; the start excitation time of controller No. 9 is 1672730220, and the excitation cycle is 90s.
[0023] S4. Shot point excitation After the controller working mode is set, the controller and the central control system exchange data through the hybrid communication network to realize the firing point excitation. During data interaction, the central control system automatically decodes the data sent by the communication network and finds that the data sent by communication networks of each priority level are all wrong. Therefore, the data of the communication network with the first priority level is taken as the main body, and the data information of the communication networks with the second, third, and fourth priority levels are integrated. The different parts of the data information are replaced and verified one by one to obtain the correct result.
[0024] For central control excitation mode controller: After receiving the ready information of the firing points 1 to 3 to be fired from the controller, the central control system places them in the sequence of firing points to be fired, calculates and selects the best firing point 2 to be fired from the sequence according to the time-distance rule, and sends the firing point information and firing time of the firing point 2. After receiving the firing time, the controller displays the countdown and fires the firing point. For time slot autonomous excitation mode controller: Autonomously fire the shots according to the preset start firing time and polling cycle without communicating with the central control system; S5. Statistical Analysis After the firing point is fired, the controller transmits firing information back. The central control system receives the firing information of the fired point and updates it in real time in the database, and marks it as fired on the display interface. At the same time, statistical analysis of the firing efficiency is also performed.

After startup, the communication network types used are preset in the application software as Beidou communication network and radio station communication network. The central control system communicates according to the selected communication network. The central control system uses a satellite timing device for timing. After the timing is successful, the system clock is calibrated to ensure that the system time is always consistent with the satellite time. The controller is connected to the communication network and satellite timing device consistent with the central control system. After the power-on self-test is normal, the satellite time is synchronized and the system clock is calibrated to ensure that the time of the controller is consistent with that of the central control system. S2. Priority setting of communication network The priority of the communication network is manually set as follows: the first priority is the Beidou communication network, and the second priority is the radio station communication network; S3. Controller working mode setting After the controller works normally, it automatically sends online status information to the central control system through the communication network and applies for its working mode. The central control system receives the application information through the first priority communication network and sends the actual working mode of the controller. The application software does not need to perform time calculations, and all time is used to control the controllers of all central control excitation modes; S4. Shot point excitation After the controller working mode is set, the controller and the central control system exchange data through the hybrid communication network to realize the firing point excitation. During data interaction, the central control system automatically decodes the data sent from the first priority communication network. If, upon inspection, the data sent from the first priority communication network is found to be erroneous, it automatically decodes the data sent from the second priority communication network. If, upon inspection, the data sent from the second priority communication network is correct, the data from the second priority communication network is adopted.
[0027] After receiving the ready information of the to-be-fired shot points 1 to 3 sent by the controller, the central control system places them in the to-be-fired shot point sequence, calculates and selects the to-be-fired shot point 1 from the sequence according to the time-distance rule, and sends the shot point information and firing time of the selected to-be-fired shot point 1. After receiving the firing time, the controller displays the countdown and fires the shot point. S5. Statistical Analysis The central control system will update the received firing information of the fired shot points in real time, add the firing information to the ready information of the next shot point and transmit it back, and mark it as fired on the display interface. The software will also perform statistical analysis on the firing efficiency.
