Description

Technical Field

[0001] The present invention relates to the technical field of highway rescue management, and in particular to a highway code scanning alarm rescue management method system and method. Background Art

[0002] In recent years, with the development of QR code scanning technology and Internet of Things (IoT) devices, QR code communication has become a more convenient means of real-time information transmission. By embedding prefabricated information (location information, content carrier, etc.) in the QR code, using smart terminals (such as smart phones, handheld terminals, etc.) to scan and identify and process the code, real-time information feedback based on the prefabricated information is obtained, and it is uploaded to the central database or command platform for feedback. This has become an effective way to improve emergency response efficiency.

[0003] As an important part of modern transportation, the safety performance of highways has attracted more and more attention. However, there are some obvious problems in the traditional highway alarm system, which have affected the safety and rescue efficiency of highways to a certain extent. The traditional highway alarm method usually relies on telephone alarm, which requires multiple links, including the alarm person dialing the alarm phone, the operator answering and recording the alarm information, and then passing the information to the command center. The whole process is cumbersome and time-consuming. In addition, due to the large traffic volume and high speed on the highway, it is often difficult for the alarm person to accurately describe his position after the fault occurs, and in areas with complex geographical locations, such as mountainous areas and urban ruins, the location is often difficult to accurately determine, which further increases the difficulty of rescue. In addition, the auxiliary signs on the highway may not be intuitive and easy to understand for the alarm person and rescue personnel. For example, signs such as Baili piles, G, and S may be difficult to accurately describe in telephone communication, which may lead to delays in rescue time. Thirdly, the existing highways often cannot automatically assess the complexity of the fault in advance during rescue, making it difficult to make accurate rescue plans. In short, the traditional method of relying on telephone alarms on highways usually increases the rescue time and affects the rescue efficiency due to inaccurate location descriptions and inaccurate descriptions of fault content.

[0004] In view of this, it is necessary to propose a highway code scanning alarm rescue management system and method to solve or at least alleviate some of the above-mentioned defects. Summary of the invention

[0023] Please refer to the attached Figure 1, the present invention provides a highway code scanning alarm rescue management system, including an alarm start module, a background server, an alarm management verification platform, an alarm receiving and rescue assistance platform and an alarm receiving and rescue management module; The alarm initiation module runs on the code scanning request terminal, and is used to scan the alarm QR code to provide an alarm information filling interface and generate a road section fault code scanning rescue signal, and send the road section fault code scanning rescue signal to the background server. The road section fault code scanning rescue signal includes the code scanning device information obtained based on the scan, the direction of the faulty road section, the coordinates of the faulty road section location, and the fault alarm type; The backend server receives the road section fault code scanning rescue signal sent by the alarm start module and distributes the road section fault code scanning rescue signal to the alarm management and verification platform, the alarm receiving and rescue assistance platform and the alarm receiving and rescue management module; The alarm management and verification platform receives the road section fault scanning rescue signal sent by the background server, verifies and feedbacks the road section fault scanning rescue signal based on the scanning device information, the direction of the faulty road section and the coordinates of the faulty road section. If the verification is successful, the platform digitally signs the successful alarm result and sends it to the alarm rescue management module. If the verification fails, the failed alarm result is fed back to the alarm initiation module through the background server. Among them, "verifying the rescue signal of the road section fault code scanning based on the code scanning device information, the direction of the faulty road section and the coordinates of the faulty road section" specifically includes: Based on the code scanning device information, the current GPS coordinates of the scanning terminal of the corresponding code scanning request terminal are obtained; If the current distance between the current GPS coordinates of the scanning terminal and the coordinates of the faulty road section location is not greater than the preset distance threshold, verification success data is generated; If the current distance between the current GPS coordinates of the scanning terminal and the coordinates of the faulty road section is greater than the preset distance threshold, the terminal historical movement direction of the corresponding scanning request terminal is obtained based on the scanning device information. If the terminal historical movement direction is consistent with the direction of the faulty road section, verification success data is generated; otherwise, verification failure data is generated; The alarm and rescue assistance platform receives the road fault code scanning rescue signal sent by the background server, obtains the fault-related information according to the road fault code scanning rescue signal, and sends the fault-related information to the alarm and rescue management module. The fault-related information includes the number of people associated with the fault and the length of the fault; The alarm and rescue management module receives the road fault code scanning rescue signal sent by the background server, receives the alarm result (failed alarm result or successful alarm result) and the platform digital signature sent by the alarm management verification platform, receives the fault-related information sent by the alarm and rescue assistance platform, and verifies the platform digital signature. If the verification is successful and it is a successful alarm result, a rescue navigation route and a rescue management plan are generated based on the road fault code scanning rescue signal and the fault-related information, and the rescue waiting result feedback is sent to the alarm start module through the background server.

[0024] The present invention provides a highway scanning alarm rescue management system and method, which attaches an alarm QR code with embedded location information and driving direction information to the side of the highway or the road surface; by using the alarm start module of the scanning request terminal to scan the alarm QR code set at the location where the road section fault occurs and fill in the alarm information to generate a road section fault scanning rescue signal, it is possible to quickly and accurately locate the fault or the specific location of the fault, and generate a request signal. The alarm QR code serves as a carrier for information transmission, has high efficiency and convenience, and can effectively shorten the rescue response time. In this step, after the user scans the alarm QR code through a mobile phone or other device, it can automatically identify and extract detailed information of the location, avoiding errors and inconveniences in the manual input process, and can also provide specific rescue process guidance according to different fault types, thereby realizing accurate recording and transmission of fault information, realizing rapid alarm and ensuring timely and effective processing of rescue requests. At the same time, the road section fault scanning code rescue signal is distributed to the alarm management and verification platform, the alarm rescue assistance platform and the alarm rescue management module through the background server. The road section fault scanning code rescue signal is further confirmed by the alarm management and verification platform. Only when the current distance between the current GPS coordinates of the scanning terminal and the coordinates of the fault section location is not greater than the preset distance threshold, or the current distance between the current GPS coordinates of the scanning terminal and the coordinates of the fault section location is greater than the preset distance threshold, and the terminal's historical moving direction is consistent with the direction of the fault section, verification success data is generated, and then the alarm rescue management module is triggered for processing, which solves the technical problem of false alarms caused by external personnel scanning QR code images due to the long-term timeliness of the alarm QR code. At the same time, the alarm and rescue assistance platform obtains fault-related information based on the road fault code scanning rescue signal. The fault-related information includes the number of people associated with the fault and the fault-related length. It can timely evaluate the fault occurrence at the coordinate position of the fault section location, so as to accurately generate a rescue management plan; finally, the alarm and rescue management module generates a rescue navigation route and a rescue management plan based on the road fault code scanning rescue signal, the number of people associated with the fault and the fault-related length. It can automatically generate a rescue navigation route and a rescue management plan based on multiple dimensions such as the location of the fault and the real-time status of the fault-related situation. It can minimize the delays, errors or unbalanced resource allocation caused by manual dispatching, and ensure that each rescue mission can be responded to in the shortest time, thereby achieving the goal of fast, efficient and accurate road fault rescue.In the scheme of the present invention, the alarm personnel make an alarm by scanning the alarm QR code, and the background server distributes the data and the road section fault scan code rescue signal is distributedly processed to realize automatic parsing of the accurate location and fault association according to the alarm QR code information, thereby improving the fault location efficiency and effectively improving the rescue efficiency. At the same time, the alarm management and verification platform judges the authenticity of the alarm data, and the alarm receiving and rescue assistance platform supplements the description of the alarm data, thereby further improving the accuracy of fault location and the comprehensive description of the fault, which is conducive to improving the rescue efficiency.

[0025] It can be understood that if the signature verification fails, or if the signature verification succeeds and the alarm result is a failed alarm, the alarm rescue management module sends feedback of the failed alarm result to the alarm initiation module through the background server; if the alarm management verification platform fails the verification, the failed alarm result will be fed back to the alarm initiation module through the background server.

[0026] The solution of the present invention verifies the digital signature of the platform to prevent the information sent by the alarm management verification platform from being tampered with.

[0027] It can be understood that the backend server is respectively connected to the alarm activation module, the alarm management verification platform, the alarm rescue assistance platform and the alarm rescue management module. In the scheme of the present invention, the alarm QR code is attached to the highway guardrail or the highway identification pile, and an alarm QR code can be set every 50 meters, or every 100 meters, or other equal-spacing or unequal-spacing forms to attach the alarm QR code to the roadside of the highway.

[0028] In the scheme of the present invention, each alarm QR code on the highway section is generated by a dedicated QR code generator according to a predetermined coding rule. Each alarm QR code is embedded with the current position coordinates and the current section direction (the reverse direction of driving is up or down). When the user uses the scanning request terminal to scan the alarm QR code, the scanning request terminal will automatically obtain the information in the alarm QR code and transmit the data to the designated processing platform through the network. The processing platform parses the QR code content and extracts the section fault scanning rescue signal containing the location, requester information and fault description. In the specific implementation, the component is laid out based on the GIS (geographic information system) technology based on the QR code position relationship library of the alarm QR code, and the actual geographic data of each alarm QR code and the driving direction of the section are mapped one by one.

[0029] It can be understood that the fault types include "vehicle minor friction traffic accident, vehicle minor collision traffic accident, vehicle chain rear-end collision accident, vehicle serious traffic accident, traffic accident with no injuries, traffic accident with minor injuries, traffic accident with serious injuries, traffic accident with multiple injuries and traffic jam". The fault types can be selected and pushed from the accident options that pop up on the web page after scanning the alarm QR code, or natural language processing technology can be used to perform semantic analysis on the fault description text in the filled-in request information, extract key information in the information (such as rescue type, fault symptoms, road location, etc.), and classify the request information according to the fault alarm type based on the classification rules preset by the system.

[0030] It can be understood that in the scheme of the present invention, since the alarm QR code is valid for a long time, in order to avoid false alarms or false alarms caused by external personnel remotely operating the alarm QR code based on historical photos, the current GPS coordinates of the scanning terminal of the code scanning request terminal and the terminal historical movement direction of the code scanning request terminal are verified, and a distributed processing method of the alarm management verification platform, the alarm and rescue assistance platform and the alarm and rescue management module is adopted, which is beneficial to improve the efficiency of rescue and avoid waste of resources.

[0031] It can be understood that the preset distance threshold can be 1000 meters, or it can be 500 meters or 100 meters, etc., which is determined according to the current environment and weather conditions of the alarm QR code; specifically, if there is a possibility that the GPS positioning drifts significantly, the preset distance threshold is set to be larger.

[0032] Furthermore, "obtaining fault-related information based on the road section fault scanning rescue signal" specifically includes: obtaining the associated GPS devices within the fault preset association range of the fault section location coordinates and the fault-associated device fusion coordinates of each associated GPS device based on the road section fault scanning rescue signal; obtaining the associated GPS devices corresponding to the fault-associated device fusion coordinates within the target association range of the fault section location coordinates as the fault-associated devices, and the target association range is within the fault preset association range; determining the fault-associated devices whose moving speed is less than the preset activity speed as the fault target devices; obtaining the number of fault target devices and the device distance between any two fault target devices; determining the number of fault target devices as the number of fault-associated people, and determining the maximum device distance as the fault association length.

[0033] More preferably, "obtaining the associated GPS devices within the fault preset associated range of the fault section location coordinates and the fault associated device fused coordinates of each associated GPS device based on the road fault scanning rescue signal" specifically includes: obtaining the device network positioning initial coordinates of each associated GPS device within the fault preset associated range of the fault section location coordinates and each associated GPS device based on the base station network positioning technology; obtaining the device GPS positioning initial coordinates of each associated GPS device within the fault preset associated range of the fault section location coordinates and each associated GPS device based on the satellite communication technology; and obtaining the fault associated device fused coordinates of each associated GPS device using a weighted average algorithm based on the device network positioning initial coordinates, the network positioning weight, the device GPS positioning initial coordinates and the GPS positioning weight. In a specific implementation scheme of the present invention, in order to further obtain detailed fault information corresponding to the road section fault scanning rescue signal, firstly, the fault-associated device fusion coordinates within the preset fault association range are obtained based on the base station network positioning technology and the satellite communication technology; and the associated GPS device corresponding to the fault-associated device fusion coordinates within the target association range is further obtained as the fault-associated device; then the average activity speed of each fault-associated device is obtained based on the base station network positioning technology and the satellite communication technology; the fault-associated device with an average moving speed less than the preset activity speed is determined as the fault target device; the number of fault target devices and the device distance between any two fault target devices are obtained; finally, the number of fault target devices is determined as the number of fault-associated people, and the maximum device distance is determined as the fault association length, and the accident status is pre-analyzed without obtaining on-site photos or the night photos are unclear, which solves the technical problem that it is difficult to accurately assess the accident status due to sparsely arranged cameras on the highway or unclear night photos.

[0034] Optionally, the preset fault association range can be a circular range with the current fault section location coordinates as the center and a radius of 1000 meters (or others); it can also be a rectangular range with the current fault section location coordinates as the center, a length of 1000 meters (or others) and a width of 5 meters (or others); the target association range can be a circular range with the current fault section location coordinates as the center and a radius of 8000 meters (or others); it can also be a rectangular range with the current fault section location coordinates as the center, a length of 800 meters (or others) and a width of 4.5 meters (or others).

[0035] It can be understood that in the present invention, base station network positioning can be achieved through signaling data interacting between the communication terminal and the base station, device GPS positioning can be achieved through the unique identifier of the device in the signaling data, and device GPS positioning can also be obtained by sending a message to the corresponding communication terminal to enable permission; wherein the sum of the network positioning weight and the GPS positioning weight is equal to 1.

[0036] Furthermore, the step of obtaining the "network positioning weight and GPS positioning weight" includes: performing device identity authentication on the scanning code request terminal corresponding to the road section fault rescue request signal to obtain the scanning terminal identity unique identifier; performing network signal stable positioning on the scanning code request terminal corresponding to the road section fault rescue request signal based on the scanning terminal identity unique identifier to obtain the scanning terminal network positioning coordinates; calculating the network positioning weight and GPS positioning weight based on the scanning terminal network positioning coordinates, the scanning terminal current GPS coordinates and the fault section location coordinates. In a specific embodiment of the present invention, if the scanning terminal network positioning coordinates are , the current GPS coordinates of the scanning terminal are , the coordinates of the fault section are , assuming the network positioning weight is , GPS positioning weight is , then , , calculate and obtain the network positioning weight and GPS positioning weight .

[0037] Furthermore, based on the network base stations in the area where the scanning code request terminal corresponding to the road section fault rescue request signal is located, network position triangulation is performed on the network signal source of the road section fault rescue scanning code request terminal to obtain the preliminary signal positioning coordinates of the terminal; multi-point signal strength collection is performed on the scanning code request terminal corresponding to the road section fault rescue request signal and the network base station in the area to obtain the network signal strength between the scanning code request terminal and the network base station in the area; based on the network signal strength between the scanning code request terminal and the network base station in the area, network communication stability is evaluated and analyzed between the scanning code request terminal corresponding to the road section fault rescue request signal and the network base station in the area to obtain the terminal network stability influencing factor; network positioning calibration is performed on the preliminary signal positioning coordinates of the terminal based on the terminal network stability influencing factor to obtain the scanning terminal network positioning coordinates. In one embodiment of the present invention, a unique device ID is stored in the scanning request terminal. Each road section fault scanning rescue signal contains the identity information of the terminal. During the scanning process, the device identity information contained therein is extracted and compared with the device database to verify its legitimacy. After the verification is completed, the unique identifier of the device (for example, device ID number, IMEI code, etc.) is returned to ensure that the identity of the device is unique and valid in the system, and finally the scanning terminal identity unique identifier is obtained. Through the scanning terminal identity unique identifier of the fault rescue request signal, it is connected to the communication network where the device is located. The scanning terminal identity unique identifier can accurately find the signal source of the device in the network. Then, the device is positioned through the base station positioning, and the multi-point positioning algorithm (such as triangulation positioning method) is used to calculate the device position according to the received signal strength, the distribution of network base stations and other parameters to generate a relatively accurate scanning terminal network positioning coordinate. The positioning process adjusts the positioning accuracy according to the communication network conditions (including network coverage, signal stability and other factors) in the area where the device is located to ensure that the obtained network positioning coordinates have sufficient accuracy, and finally the scanning terminal network positioning coordinates are obtained.

[0038] Furthermore, there may be certain difficulties in simultaneously acquiring the initial coordinates of the device network positioning and the initial coordinates of the device GPS positioning. In order to further acquire the fused coordinates of the fault-associated devices of each associated GPS device, the acquisition of the associated GPS devices "acquires the associated GPS devices within the preset associated range of the fault location coordinates of the fault section and the fused coordinates of the fault-associated devices of each associated GPS device based on the rescue signal of the road section fault scanning code" specifically includes: acquiring the initial coordinates of the device network positioning of each associated GPS device within the preset associated range of the fault location coordinates of the fault section and each associated GPS device based on the base station network positioning technology; correcting the initial coordinates of the device network positioning using the network positioning correction matrix, and calculating the fused coordinates of the fault-associated devices of each associated GPS device, wherein the network positioning correction matrix is ​​determined based on the scanning terminal network positioning coordinates and the fault section location coordinates.

[0039] It can be understood that in the solution of the present invention, when acquiring the faulty target device, the fusion correction acquisition is performed based on GPS positioning and base station network positioning. If GPS positioning cannot be obtained, it can be determined only by base station network positioning. Optionally, the preset activity speed can be 0.5 kilometers per minute, or other values, as long as the preset activity speed is used to determine whether it is at a vehicle speed, a pedestrian speed, or a stationary speed.

[0040] Preferably, in order to avoid the situation where a user carries multiple mobile devices resulting in an inflated number of fault-associated people, the step of "obtaining the number of fault target devices" specifically includes eliminating one of the fault target devices if the device distance between two fault target devices is within a near-zero range, and using the other fault target device as the currently calculated fault target device; optionally, the near-zero range can be a 0.1 meter range, a 0.2 meter range, a 0.3 meter range or other range values.

[0041] Furthermore, the step of "obtaining the terminal historical movement direction of the corresponding scanning request terminal based on the scanning device information" specifically includes: obtaining the location coordinates of the faulty section and multiple target communication base stations corresponding to its upstream and downstream; obtaining the signaling data and timestamp corresponding to the target communication base station associated with the scanning device information; and determining the terminal historical movement direction based on the signaling data and timestamp. In one specific embodiment of the present invention, a training database is established, which contains switching data of each known base station, base station signal connection strength and timestamp signaling data as input data, and the uplink result or downlink result in the training database is used as output data, a support vector machine model is established, and the historical movement direction of the terminal is determined based on the support vector machine model and the current signaling data; in another specific embodiment of the present invention, the signaling data is sorted according to the timestamp to form an ordered data sequence, and the movement trajectory is analyzed based on the ordered data sequence to determine the historical movement direction of the terminal; specifically, the signaling data of adjacent timestamps are compared to observe the changes in the base station sequence. If the signaling data shows that the terminal is connected to base station A and base station B successively, it can be preliminarily determined that the movement direction of the terminal is from A to B; the signal strength change can be further combined to assist the judgment. If the signal strength of the terminal continues to weaken during the movement, and switches to a base station in a certain direction, it further proves that the terminal is away from the base station in that direction, thereby strengthening the judgment of the movement direction.

[0042] Furthermore, the step of "generating a rescue navigation route and a rescue management plan based on the rescue signal scanned by the road section fault and the fault-related information" specifically includes: automatically adapting the map to navigate based on the coordinates of the fault section location and the direction of the fault section to generate a rescue navigation route; determining the rescue priority based on the number of people associated with the fault, the length of the fault, and the type of fault alarm. In the specific implementation, the map API is used to automatically adapt the map to navigate, determine the fault level based on the number of people associated with the fault, the length of the fault, and the type of fault alarm, and generate the corresponding rescue priority and rescue type based on the fault level.

[0043] In a specific implementation of the present invention, a weight for the number of rescuers, a weight for the rescue-related length, and a weight for the alarm type are set, and the current rescue score is calculated based on the number of fault-related people, the fault-related length, the fault alarm type, the weight for the number of rescuers, the weight for the rescue-related length, and the weight for the alarm type. The current rescue score is numerically matched with the rescue priority library to obtain the rescue priority.

[0044] Furthermore, the user performs scan code rescue request processing on the alarm QR code set at the location where the road fault occurs through the scan code request terminal to obtain the road fault scan code rescue request information source; performs information security verification on the road fault scan code rescue request information source to obtain the road fault scan code rescue safety verification result; extracts and classifies the request content corresponding to the real rescue request information in the road fault scan code rescue safety verification result to obtain the road fault scan code rescue request type data; performs communication signal encryption transmission conversion on the road fault scan code rescue request type data to generate a road fault scan code rescue request communication encryption transmission signal; uploads the road fault scan code rescue request communication encryption transmission signal to the background server corresponding to the scan code request terminal to decode the request information to obtain the road fault scan code rescue request, and receives and responds to the road fault scan code rescue request to generate a road fault rescue request signal.

[0045] Please refer to the attached Figure 2 The present invention also provides a highway code scanning alarm rescue management method, which is used for the above-mentioned highway code scanning alarm rescue management system, comprising the steps of: The alarm start module scans the alarm QR code on the on-site identification pile, fills in the alarm information through the alarm information filling interface, and sends the road section fault scan code rescue signal containing the identification pile information and the reported alarm information to the background server; The backend server receives the road section fault scan code rescue signal and distributes it; The alarm management platform verifies and feeds back the rescue signal of the road fault code scanning. If the verification is successful, the platform digitally signs the successful alarm result and sends it to the alarm rescue management module. If the verification fails, the failed alarm result is fed back to the alarm start module through the background server. The alarm and rescue assistance platform obtains fault-related information based on the rescue signal scanned by the road fault section; The alarm rescue management module verifies the digital signature of the platform. If the verification is successful, it generates a rescue navigation route and rescue management plan based on the road fault code scanning rescue signal and fault-related information, and sends rescue waiting result feedback to the alarm start module through the background server.

[0046] The above embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be understood as limiting the scope of the present application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the present application shall be subject to the attached claims.
