[0020] The present invention proposes a cooperative communication method and system for electric power support vehicles based on peacetime and wartime integration.

[0021] The embodiment of the present invention provides a coordinated communication method for electric power support vehicles based on peacetime and wartime integration, referring to Figure 1 , Figure 1 The present invention is a flowchart of an embodiment of a method for cooperative communication of electric power support vehicles based on the combination of peacetime and wartime.

[0022] like Figure 1As shown, the electric power support vehicle cooperative communication method based on the combination of peacetime and wartime includes: Step S100: constructing a basic communication network of the power supply vehicle to enable the power supply vehicle to communicate with the command center; Step S200: merging the data of the plurality of power supply vehicles based on the ultra-power Bluetooth technology, and transmitting the merged data back to the command center for interpretation; Step S300: determining the communication status of the power support vehicle in real time, and determining and ensuring combat readiness communication according to the determination result; Step S400: In a combat readiness environment, a second-level communication is constructed based on the first-level communication to compress the on-site pictures and transmit them back to the command center for decompression; Step S500: When the power supply vehicle and the command center cannot communicate, information delayed synchronization is performed.

[0023] In one embodiment, a basic communication network of a power supply vehicle is constructed to enable the power supply vehicle and the command center to communicate, including: dividing the communication content between the power supply vehicle and the command center to obtain a communication code; constructing a data dictionary corresponding to the communication code on the server side of the command center; judging the communication status of the power supply vehicle in real time, and communicating the communication status with the satellite in the form of the communication code, and transmitting the communication code back to the server side of the command center via the satellite; if the base station signal meets the preset communication requirements, transmitting text interpretation information to the server side of the command center via the base station; comparing the communication code returned by the satellite and the text interpretation information returned by the base station, and optimizing the data dictionary based on the comparison result.

[0024] Specifically, Figure 2 Step S1 shown, based on the on-site positioning and communication of Beidou satellites and base stations, realizes the construction of the basic communication network of the power on-site support vehicle, supports the real-time synchronization of the support vehicle data and the command center when the communication network facilities are complete, and in this embodiment, the encryption algorithm can also be customized to realize confidential communication of data.

[0025] In one embodiment, the communication content between the power supply vehicle and the command center is divided to obtain a communication code, including: numbering the power supply vehicles in the area, and storing the numbers in 6-bit binary; dividing the execution tasks of the power supply vehicle into multiple task categories, and saving the task categories in 6-bit binary; gridding the operation area of ​​the power supply vehicle to divide it into multiple grid areas, and saving the grid areas in 20-bit binary; dividing the current status of the power supply vehicle into different categories to obtain multiple support vehicle states, and saving the support vehicle state in 4-bit binary; saving the feedback information from the power supply vehicle to the command center in 6-bit binary; and using the saved number, task category, grid area, support vehicle state and feedback information as a communication code.

[0026] It should be noted that this embodiment is described by taking the communication content between the power supply vehicle and the command center requiring a communication code of 42 bits of data as an example.

[0027] Specifically, step S100 may include steps 1.1 to 1.4. First, in step 1.1, the communication content between the power supply vehicle and the command center is sorted out and further divided. A total of 42 bits of data "communication code" are required to complete all communications.

[0028] For example, a) the power supply vehicles in the area are numbered and stored in 6-bit binary format, which can store 64 (2 6 ) power supply vehicles; b) divided into multiple categories according to the tasks to be performed, stored in 6-bit binary, a total of 64 (2 6 ) different task categories; c) grid the work vehicle area (for example, 100 square kilometers), each grid is 100 square meters (10×10), divided into 1,000,000 grid areas, and a total of 20 bits of binary are required to store; d) divide the current status of the power support vehicle into different categories, such as "mission completed", "unable to reach the designated area", "reached the designated area, mission in progress", etc., and save it in 4 bits of binary, and a total of 16 types of power support vehicle status can be stored; e) the information that the power support vehicle needs to feedback to the command center is saved in 6 bits of binary, such as "request more support vehicles for support", "medical personnel are required to enter the site", "support vehicle is damaged", etc., and a total of 64 different feedback information can be stored.

[0029] Specifically, in step 1.2, on the command center server side, a data dictionary of communication codes is constructed, and one-to-one corresponding interpretation data is configured for each communication code.

[0030] Specifically, step 1.3 determines the communication status of the current on-site operation support vehicle in real time, communicates with the satellite in the form of a communication code, and transmits information back to the server side of the command center through satellite communication; if the base station signal is good (meets the preset communication requirements), then detailed text explanation information is transmitted back to the command center through the base station.

[0031] Specifically, in step 1.4, the communication code transmitted by the satellite and the text interpretation information transmitted by the base station are compared, and the data dictionary of the command center server can be optimized in real time according to the comparison result.

[0032] In one embodiment, the data of multiple power support vehicles are merged based on ultra-power Bluetooth technology, and the merged data is transmitted back to the command center for interpretation, including: installing an ultra-power Bluetooth device on the power support vehicle, and establishing a Bluetooth connection between the power support vehicles based on the ultra-power Bluetooth device; constructing a graph data structure with the power support vehicle as a node; for each connected graph of the graph data structure, determining a base support vehicle and merging communication data based on the base support vehicle to achieve information-integrated satellite communication; communicating with the satellite through the base support vehicle to transmit the merged data back to the server side of the command center for interpretation.

[0033] Specifically, Figure 2 Step S2 shown is collaborative communication among multiple on-site support vehicles based on ultra-power Bluetooth: Since satellite communication is too expensive, when the power operation site needs to rely on communication satellites for communication, the information data of multiple support vehicles can be merged, and communication with the satellite can be centralized to transmit data back to the command center.

[0034] In one embodiment, for each connected graph of the graph data structure, a base point support vehicle is determined and communication data is merged based on the base point support vehicle, including: for each connected graph of the graph data structure, optionally a node in the connected graph and the power support vehicle corresponding to the node is used as the base point support vehicle; based on the base point support vehicle, communication tasks between all support vehicles and satellites in the connected graph are performed; communication data of each node in the connected graph is collected at a fixed time period; and the same information in the communication data of each node is merged.

[0035] Specifically, step S200 may include steps 2.1 to 2.5.

[0036] Exemplarily, in step 2.1, an ultra-power Bluetooth device is installed on the power support vehicle. The main parameters of the ultra-power Bluetooth device ensure that the Bluetooth communication distance is long, for example, more than 200 meters. Step 2.2, the support vehicle for on-site operations collects data from other support vehicles that can communicate. Other support vehicles are mainly power support vehicles that can establish Bluetooth connections. Step 2.3, construct a graph data structure with the support vehicle as the node. A graph data structure is an abstract data type used to represent a set of objects (called vertices or nodes) and various types of relationships between these objects (called edges). In a graph data structure, vertices usually represent entities, while edges represent the relationship or connection between these entities. In this embodiment, the "edge" in the graph data structure indicates that a Bluetooth connection can be established between two power support vehicles. Step 2.4: For each connected graph, realize information-integrated satellite communication, specifically: a) First, select a node (power support vehicle) in the connected graph, and use the power support vehicle of this node as the base support vehicle to undertake the communication task between all power support vehicles and satellites in the connected graph; b) Collect information of each node in the connected graph in a fixed time period, which can be interactively defined by on-site staff (for example, 10 minutes); c) Assuming that there are n nodes in the connected graph, the amount of original data is 42n bits; d) Since the tasks performed by the support vehicles in the same site have certain similarities, the communication data can be merged: 1) The positioning address distance is recorded as the relative position (distance from the base support vehicle); 2) The same information parts (task and feedback information) are merged and transmitted at one time. Step 2.5: Through the base support vehicle and satellite communication, the satellite sends the coded information to the server of the command center, which is interpreted by the server to obtain the real-time information of different support vehicles.

[0037] In one embodiment, the communication status of the power support vehicle is judged in real time, and the combat readiness communication is determined and guaranteed based on the judgment result, including: real-time monitoring of the communication status of the power support vehicle; if the base station signal meets the preset communication requirements, the main communication task between the power support vehicle and the command center is realized through the base station and the connection is confirmed through the interactive feedback mechanism with the base station; if the base station signal does not meet the preset communication requirements, the primary communication and the secondary communication are realized through the satellite; if the satellite communication cannot be carried out, the information is stored locally for delayed communication.

[0038] It should be noted that if Figure 2 Step S3 shown, real-time determination of peacetime and wartime communication status: Based on the concept of "service in peacetime and support in wartime", the power operation support vehicle needs to determine and support the wartime communication through real-time determination of the communication status. Here, the use environment may include extreme conditions such as wartime status. Specifically, step S300 may include steps 3.1 to 3.4.

[0039] Exemplarily, in step 3.1, the communication status can be manually specified or monitored in real time by the system. Step 3.2, when the system needs to monitor in real time, if the base station communication works well (meets the preset communication requirements), the base station is responsible for the main communication task between the guarantee vehicle and the command center, and confirms the connection through the "interaction-feedback" mechanism with the base station. Step 3.3, if base station communication cannot be achieved, communication is achieved through satellite, and the first-level communication is achieved by communication code. At the same time, whether to carry out second-level communication at the same time is considered based on real-time bandwidth redundancy; among them, first-level communication: "communication code" to ensure basic functions and instructions; second-level communication: auxiliary on-site picture information; first-level communication has a higher priority than second-level communication. Step 3.4, if satellite communication cannot be achieved, local storage of information is performed to prepare for subsequent delayed communication.

[0040] In one embodiment, in a combat readiness environment, a secondary communication is constructed based on the primary communication to compress the on-site pictures and transmit them back to the command center for decompression, including: in a combat readiness environment, on the basis of the primary communication using the communication code, a secondary communication is constructed according to real-time bandwidth redundancy; wherein the priority of the primary communication is higher than that of the secondary communication; compression preprocessing of the on-site pictures is performed through edge computing to obtain compressed on-site pictures; a decompression module is constructed on the server side of the command center; and the compressed on-site pictures are transmitted back to the command center for decompression through the secondary communication.

[0041] In one embodiment, compression preprocessing of on-site pictures is performed through edge computing to obtain compressed on-site pictures, including: obtaining a on-site video stream, parsing the on-site video stream into frame-by-frame images; using a semantic segmentation model to perform semantic segmentation on the frame-by-frame images to obtain segmentation results; performing secondary classification on the segmentation results according to different categories to obtain targets of different categories; and using different storage methods to store targets of different categories.

[0042] It is understandable that if Figure 2 Step S4 shown, compression coding of combat readiness environment image information: In a combat readiness environment, in order to ensure a more accurate grasp of the power site operation environment, it is necessary to build a secondary communication service based on the primary communication to realize the transmission of on-site images back to the command center. At the same time, in order to ensure that the amount of information is as small as possible, it is necessary to realize data compression preprocessing through edge computing (the workstation that comes with the support vehicle), and at the same time build a decompression module on the server side. Specifically, step S400 may include steps 4.1 to 4.5.

[0043] Exemplarily, step 4.1, constructing the image compression process of the power field operation support vehicle: first, it is necessary to parse the on-site video stream into frame images, and extract different targets from the frame images. The specific implementation may include: a) decomposing the continuous video stream (for example, a continuous half-hour video stream) into frame-by-frame images, and using a semantic segmentation model to perform semantic segmentation on each frame image to obtain a segmentation result; b) performing secondary classification on the segmentation results according to different categories, for example, including: support vehicles, work site background (buildings, vegetation, roads), personnel, movable objects, etc.

[0044] For example, in step 4.2, different storage methods are used for different categories of targets extracted from the frame image. The specific implementation may include: a) for the power supply vehicle, the relative coordinates of its center (the plane coordinates in the frame image) are recorded; b) for the scene background, no storage is performed; c) for the scene personnel, the scene workers are recorded, and their bone shapes (such as Figure 3 d) For movable objects, record their coordinates, images, and belonging numbers (defined in subsequent steps).

[0045] Exemplarily, in step 4.3, a database is constructed on the server side of the command center. The database can be used to store pictures corresponding to the numbers of power supply vehicles. Specific implementations may include: a) storing three-dimensional images of power supply vehicles with different numbers; b) storing three-dimensional scenes of the on-site working location: assuming that the working scene is entered in advance in the map grid area; if there is no on-site scene, it is collected in real time to provide three-dimensional scene data support on the server side for subsequent use; c) for movable objects, its number, coordinates and three-dimensional image are recorded; referring to the above steps, if there is no movable object on the server side, the number, coordinates and three-dimensional image of the object are collected in real time on-site at one time.

[0046] Exemplarily, in step 4.4, when collecting combat readiness environment pictures, only the coordinates of the power support vehicle, the skeleton image of the person, the coordinates of the person, and the movable item number and coordinates are transmitted.

[0047] Exemplarily, in step 4.5, on the server side, by collecting the returned information and combining it with the information in the server-side database, a real-time picture of the on-site operation in the combat readiness environment is restored.

[0048] In one example, when parsing a live video stream into frame images and extracting different targets from the frame images, the following steps can be taken: capturing a video stream; reading frames in the video stream in a loop, and processing each frame after reading it; before trying to detect or identify targets in the frame, it is necessary to perform some preprocessing steps on the frame, such as scaling, cropping, grayscale conversion, filtering, etc., to improve the accuracy and efficiency of subsequent target detection; using different algorithms to detect and extract different targets in the frame, where target detection algorithms include but are not limited to: for targets with specific colors or shapes, color histograms, edge detection, and other color- or shape-based techniques can be used to extract them; feature detection algorithms such as SIFT, SURF, and ORB are used to identify and track targets with specific features; and convolutional neural networks (CNNs) are used for target detection, such as YOLO, SSD, and Faster R-CNN. Deep learning algorithms.

[0049] In one embodiment, when the power support vehicle cannot communicate with the command center, delayed information synchronization is performed, including: aggregating support vehicle data in the area via a Bluetooth local area network, and regularly storing the aggregated data in a local server of the base support vehicle; determining the on-site conditions and automatically grading the risks to obtain a determination result; connecting with the operator's mobile device in real time via the local area network to synchronize the data of the base support vehicle; monitoring the communication signal of the mobile device in real time, and sending an early warning prompt to the mobile device when the determination result is a high-risk work site.

[0050] It is understandable that if Figure 2 Step S5 shown, information delay synchronization based on self-built base station: When the support vehicle cannot communicate with the command center in any way at the power operation site, it is necessary to build an information delay synchronization process. Specifically, step S500 may include steps 5.1 to 5.3.

[0051] Exemplarily, in step 5.1, the power support vehicle at the work site can aggregate the data of the power support vehicles that are Bluetooth-connectable (under a connectivity graph structure) in the area through a Bluetooth local area network, and store it in the local server of the base support vehicle at regular intervals (for example, every 10 minutes).

[0052] Exemplarily, step 5.2, construct an intelligent on-site condition determination process to achieve automatic classification of on-site risks: a) first identify the skeleton image of the person. If the person is identified to be in an abnormal motion state (such as lying on his side for a long time or repeatedly moving at high speed, etc.), it is marked as a high-risk work site; wherein, the repeated high-speed movement state can calculate the person's movement speed through frame difference, and set a threshold for judgment; b) Construct on-site fire point monitoring. If there is a fire point at the work site, it is determined to be a high-risk work site; c) For the semantic segmentation results in the previous steps, extract the on-site background (such as buildings, vegetation, roads), and determine whether the coordinates of the on-site background are offset by the frame difference of the frame image. If offset occurs, it is determined to be a high-risk work site.

[0053] Exemplarily, in step 5.3, an "automatic intelligent warning" APP can be installed on the operator's mobile device, such as a mobile phone. The APP has the following features: a) It is connected to the base support vehicle in real time through the local area network and synchronizes the data in the base support vehicle; b) It monitors the mobile phone communication signal in real time (the support vehicle has no satellite and base station signals, and the mobile phone also has no signal), and prompts the operator if a high-risk operation site occurs; c) The operator can handle the relevant risks on site and manually assess whether they need to move to the "signal" area to report.

[0054] It should be noted that the method described in this embodiment is used to realize the coordinated communication of the support vehicles based on the combination of peacetime and wartime at the power site. Compared with satellite communication and Bluetooth local area communication, the method described in this embodiment can realize the perception of the on-site conditions of power operations by classifying and compressing the on-site data in a way of transmitting the shortest amount of information. Through the smallest possible information interaction, the power site operation information is transmitted back to the command center in a more real and comprehensive manner, which has strong practical significance and application value.

[0055] This embodiment provides a method for collaborative communication of power supply vehicles based on peacetime and wartime integration, including: constructing a basic communication network for power supply vehicles to enable communication between the power supply vehicles and the command center; merging data of multiple power supply vehicles based on ultra-power Bluetooth technology, and transmitting the merged data back to the command center for interpretation; judging the communication status of the power supply vehicles in real time, and judging and ensuring combat readiness communication based on the judgment results; in a combat readiness environment, constructing secondary communication based on primary communication to compress the on-site pictures and transmit them back to the command center for decompression; performing information delay synchronization when the power supply vehicle and the command center cannot communicate. In this embodiment, by classifying and compressing the on-site data, the perception of the on-site conditions of the power operation is realized in a way of transmitting the shortest amount of information, so that the power on-site operation information is transmitted back to the command center more quickly, accurately, truthfully and comprehensively through as little information interaction as possible, ensuring the efficient and stable communication of the power supply vehicles at the operation site, which has strong practical significance and application value.

[0056] In addition, an embodiment of the present invention also proposes a storage medium, on which is stored a collaborative communication program for electric power supply vehicles based on the combination of peacetime and wartime. When the collaborative communication program for electric power supply vehicles based on the combination of peacetime and wartime is executed by a processor, the steps of the collaborative communication method for electric power supply vehicles based on the combination of peacetime and wartime as described above are implemented.

[0058] like Figure 4 As shown, the electric power support vehicle cooperative communication system based on peacetime and wartime integration includes: On-site positioning and communication module 100, used to build a basic communication network for the power supply vehicle so that the power supply vehicle and the command center can communicate; A Bluetooth collaborative communication module 200 is used to merge the data of the plurality of power supply vehicles based on the ultra-power Bluetooth technology, and transmit the merged data back to the command center for interpretation; The peacetime and wartime communication status determination module 300 is used to determine the communication status of the power support vehicle in real time, and to determine and ensure the wartime communication according to the determination result; The combat readiness environment compression coding module 400 is used to build a secondary communication based on the primary communication in a combat readiness environment, so as to compress the on-site pictures and transmit them back to the command center for decompression; The information delay synchronization module 500 is used to perform information delay synchronization when the power supply vehicle and the command center cannot communicate.

[0059] In one example, if Figure 5As shown, the electric power support vehicle cooperative communication system based on the combination of peacetime and wartime can include the following functional modules: an on-site positioning and communication module 10 based on Beidou satellites and base stations, an on-site multi-support vehicle cooperative communication module 20 based on ultra-power Bluetooth, a real-time determination module 30 for peacetime and wartime communication status, a combat readiness environment image information compression and encoding module 40, and an information delay synchronization module 50 based on a self-built base station.

[0060] Specifically, the on-site positioning and communication module 10 based on Beidou satellites and base stations: The main functions of this module include: realizing the construction of the basic communication network of the power on-site support vehicle, supporting the real-time synchronization of the support vehicle data and the command center under the condition of complete communication network facilities, and customizing the encryption algorithm to realize the confidential communication of data. Among them, the custom encryption algorithm can include symmetric encryption algorithm and asymmetric encryption algorithm. The symmetric encryption algorithm uses the same key for encryption and decryption, and the communicating parties need to share the key securely. The symmetric encryption algorithm includes but is not limited to the DES symmetric encryption algorithm, 3DES (an improved version of DES), AES symmetric encryption algorithm, Blowfish symmetric key encryption algorithm, Twofish (a subsequent version of Blowfish) and Serpent encryption algorithm. The asymmetric encryption algorithm uses a pair of keys: a public key and a private key. The public key is used to encrypt data and the private key is used to decrypt data. The asymmetric encryption algorithm includes but is not limited to the RSA asymmetric encryption algorithm, ECC, Diffie-Hellman key exchange protocol, DSA digital signature algorithm, ElGamal asymmetric encryption algorithm, etc. Other encryption algorithms can also be used: IDEA symmetric encryption algorithm, GPG / PGP (encryption tools including symmetric encryption, asymmetric encryption, hash functions and digital signatures), SSL / TLS (Internet encryption communication protocol) and IPsec protocol.

[0061] Exemplarily, first, the communication content between the support vehicle and the command center is sorted out, and the communication content is further divided, requiring a total of 42 bits of "communication code"; then, on the command center server side, a "communication code" data dictionary is constructed, and one-to-one explanation data is configured for each code; then, the communication status of the current on-site operation support vehicle is judged in real time, and the satellite is communicated in the form of a "communication code", and the information is transmitted back to the command center server through satellite communication; if the base station signal is good, detailed text explanation information is transmitted back to the command center through the base station; finally, the "communication code" transmitted by the satellite and the text explanation information transmitted by the base station are compared, and the data dictionary in the command center server is optimized in real time according to the comparison results.

[0062] Specifically, the on-site multi-support vehicle collaborative communication module 20 based on ultra-power Bluetooth: The main functions of this module include: Since the cost of satellite communication is too high, when the power operation site needs to rely on communication satellites for communication, the information data of multiple support vehicles can be merged, and communication with the satellite can be centralized to transmit data back to the command center.

[0063] Exemplarily, first, an ultra-power Bluetooth device is installed on the vehicle (power support vehicle), and the main parameters of the ultra-power Bluetooth device ensure that the Bluetooth communication distance is more than 200 meters; then, through the support vehicle operating on site, the data of other support vehicles that can communicate are collected, and the other support vehicles are mainly which ones can establish Bluetooth connections; then, with the support vehicle as the node, a graph data structure is constructed, and the "edge" in the graph indicates that a Bluetooth connection can be established between two support vehicles; then, for each connected graph, information-integrated satellite communication is realized; finally, through the base support vehicle and satellite communication, the satellite sends the encoded information to the command center server, and the server interprets it into real-time information of different support vehicles.

[0064] Specifically, the module 30 for real-time determination of peacetime and wartime communication status: the main functions of this module include: based on the concept of "service in peacetime and support in wartime", the electric power operation support vehicle needs to determine and support the combat readiness communication through real-time determination of the communication status.

[0065] Exemplarily, first, the communication status can be manually specified or monitored in real time by the system: when the system needs to monitor in real time, if the base station communication works well, the base station is responsible for the main communication task between the vehicle and the command center; the connection is confirmed through the "interaction-feedback" mechanism with the base station; then, if the base station communication cannot be achieved, communication is achieved through satellite, and the "communication code" method is used to achieve "primary communication". At the same time, based on the real-time bandwidth redundancy, consider whether to carry out "secondary communication" at the same time; among them, primary communication: ensure the "communication code" of basic functions and instructions; secondary communication: auxiliary on-site picture information; primary communication has a higher priority than secondary communication; finally, if satellite communication cannot be achieved, local storage of information is done to prepare for subsequent delayed communication.

[0066] Specifically, combat readiness environment image information compression encoding module 40: The main functions of this module include: in a combat readiness environment, in order to ensure a more accurate grasp of the power site operating environment, it is necessary to build a "secondary communication" service on the basis of "primary communication" to realize the transmission of on-site images back to the command center. At the same time, in order to ensure that the amount of information is as small as possible, it is necessary to implement data compression preprocessing through edge computing (for example, through the workstation brought by the support vehicle), and build a decompression module on the server side.

[0067] Exemplarily, the image compression process of the power field operation support vehicle is constructed: first, the on-site video stream needs to be parsed into frame images, and then different targets are extracted from the frame images; then, different storage methods are used for different categories of targets extracted from the frame images; then, on the command center server side, a database is built to store pictures corresponding to the numbers; then, when collecting pictures in a combat readiness environment, only the support vehicle coordinates, human skeleton images, human coordinates, movable item numbers and coordinates are transmitted; finally, on the server side, by collecting the returned information and combining it with the information in the server-side database, the real-time pictures of the on-site operations in the combat readiness environment are restored.

[0068] Specifically, the information delay synchronization module 50 based on the self-built base station: The main functions of this module include: when the support vehicle cannot communicate with the command center in any way at the power operation site, it is necessary to build an information delay synchronization process.

[0069] For example, first, the support vehicle at the work site, through the Bluetooth local area network, aggregates the data of the support vehicles that can be connected by Bluetooth (under the connected graph structure) in the area, and stores it regularly (for example, every 10 minutes) in the local server of the base support vehicle; then, an intelligent judgment system for the site conditions is built to realize the automatic classification of site risks; then, the "automatic intelligent early warning" APP is installed on the mobile devices of the operators, such as mobile phones; finally, the coordinated communication and safety early warning of the support vehicles in peacetime and wartime at the power site are realized.

[0070] It can be understood that the coordinated communication system of the power support vehicle based on the combination of peacetime and wartime in this embodiment is used to realize the coordinated communication of the support vehicle based on the combination of peacetime and wartime in the power field. Compared with satellite communication and Bluetooth local area communication, this embodiment can realize the perception of the power operation field conditions in the shortest information transmission method by classifying and compressing the field data. Through the smallest possible information interaction, the power field operation information is transmitted back to the command center in a more real and comprehensive manner, which has strong practical significance and application value.

[0071] This embodiment provides a collaborative communication system for power support vehicles based on the combination of peacetime and wartime. By classifying and compressing on-site data, it realizes the perception of the on-site conditions of power operations in a way that transmits the shortest amount of information. Therefore, through the smallest possible information interaction, the power on-site operation information is transmitted back to the command center more quickly, accurately, truthfully and comprehensively, ensuring efficient and stable communication of the power support vehicle at the operation site, which has strong practical significance and application value.

[0072] It should be noted that the technical details that are not fully described in the embodiment of the cooperative communication system for power supply vehicles based on the integration of peacetime and wartime can be referred to the cooperative communication method for power supply vehicles based on the integration of peacetime and wartime as described above provided in any embodiment of the present invention, and will not be repeated here.
