Description

Technical Field

[0001] This invention relates to the field of fire truck rescue parking management technology, specifically to a fire truck parking management method and system based on emergency management. Background Technology

[0002] With the acceleration of urbanization and the continuous increase in the number of buildings, the importance of fire safety has become increasingly prominent. Fire lanes, as lifelines in emergencies, must be kept unobstructed. However, the obstruction of fire lanes is a frequent occurrence, which not only violates safety regulations but can also lead to serious consequences in emergencies.

[0003] In existing technologies, solutions using visual analysis technology for fire lane occupancy detection significantly improve efficiency and accuracy through automated and intelligent detection methods. However, even if the fire lane is not blocked, fire trucks can easily encounter oncoming traffic and cause congestion while driving in the limited space, affecting rescue time. This is especially true in poorly constructed residential areas where fires prevent fire trucks from reaching the fire location immediately. Furthermore, improperly parked fire trucks can hinder subsequent firefighting operations, further obstructing fire lanes. Therefore, it is essential to design a fire truck parking management method and system based on emergency management, with strong rescue location prediction capabilities and a high degree of fire early warning and dispatch capabilities. Summary of the Invention

[0004] The purpose of this invention is to provide a method and system for managing the parking of fire trucks based on emergency management, so as to solve the problems mentioned in the background art.

[0005] To address the aforementioned technical problems, this invention provides the following technical solution: a fire truck parking management method and system based on emergency management, comprising:

[0006] The target road locations to be analyzed are filtered from the road monitoring data, and the ability of fire trucks to pass through the target roads is analyzed. The target road locations to be analyzed are located based on the obstacle parking data of the fire warning location.

[0007] If it is detected that the fire truck can pass through the target road, based on the road monitoring data corresponding to the location of the target road, the possibility of the fire truck encountering a blockage during its entry into the target road is predicted, and the most suitable driving route is obtained and sent to the fire truck in combination with the probability prediction results.

[0008] As the fire truck travels along the route to the target road, when the fire truck reaches the meeting point on the target road, the fire truck is instructed to park based on the nearest parking position to the fire warning location.

[0009] Based on the most suitable driving route and the nearest parking location, the parking locations of subsequent fire trucks corresponding to the urban fire resources are managed by the emergency management platform after being combined with urban fire resources.

[0010] According to the above technical solution, the step of filtering the target road locations to be analyzed from the road monitoring data includes:

[0011] The target road is monitored, including both sides and the center of the road. A road plan diagram is obtained using map software, and the location of the target road is marked on the road plan diagram based on the road monitoring data.

[0012] Further, the target road location is obtained from the direction of the emergency warning location in the road plan diagram. The direction of the emergency warning location is the road direction that leads to the emergency warning location in the road plan diagram. When the road extension location is not identified in the road monitoring data, the road extension location is marked as not conforming to the current road perpendicularity, and the limit distance of the road monitoring data is set to the road segment distance that conforms to the road perpendicularity. The road width of the road segment distance is obtained as K meters.

[0013] According to the above technical solution, the analysis of whether the fire truck can pass through the target road includes:

[0014] In the target road, at every L-meter interval, the number of obstacles appearing on the road is identified sequentially, and the number of marked obstacles is counted as A. Based on the marked obstacles, the drivable width of the target road is reduced according to the marked obstacles on the target road.

[0015] Identifying the features of objects appearing in the target road includes:

[0016] The target road is monitored sequentially at L-meter intervals to monitor whether the area occupied by the object feature exceeds δ% of the area of ​​each L-meter interval. If it exceeds, it is marked as an obstacle; otherwise, it is marked as a non-obstacle. Here, δ is the proportion of the smallest obstacle feature in each L-meter interval.

[0017] Based on the marked obstacles, the database is searched for the additional driving road area required for a fire truck with an width of m meters and a length of n meters to avoid the obstacles, which is s. The additional driving road area is formed by a plane consisting of at least a target road with a width of M meters and a length of N meters. The area corresponding to the additional driving road area does not completely overlap with the area corresponding to the target road area where the fire truck enters at intervals of L meters when at least one obstacle appears in each interval of L meters, where M > m and N > n. The drivable road area is compared with the driving road area.

[0018] The drivable area of ​​the target road is obtained as W = AMN - x - μ1, where 1 ≤ i ≤ A, and C is the area of ​​the obstacle. i Let A be the area of ​​each obstacle on the target road, and let x be the overlapping area of ​​the additional driving road area within each L-meter interval. x is related to A. If the drivable area of ​​the road is greater than the driving area, μ1 is the error value of the drivable area of ​​the target road. Output a command indicating that the fire truck can pass through the target road; otherwise, output a command indicating that the fire truck cannot pass through the target road.

[0019] According to the above technical solution, if it is detected that a fire truck can pass through the target road, based on the road monitoring data corresponding to the location of the target road, the possibility of congestion during the fire truck's entry into the target road is predicted, including:

[0020] Monitoring traffic flow on the target road includes: obtaining the number of vehicles Z passing through the target road through road monitoring data, wherein the number of vehicles includes vehicles passing through the target road from two opposite directions, and the detection accuracy of the vehicles is determined based on the size of the area occupied by the vehicle features in the road monitoring data.

[0021] The possibility of a blockage during the fire truck's entry into the target road. Where β is the unit conversion parameter.

[0022] According to the above technical solution, when monitoring the meeting point of the fire truck upon reaching the target road along the driving route, and combining this with the obtained parking position closest to the fire warning location, instructing the fire truck to park includes:

[0023] Based on the traffic flow, the number of vehicles passing through the road segment within a unit time period is obtained. The unit time period is set to ensure that the number of vehicles passing through the road segment within the unit time period is at least 2 and their travel directions are not the same. Based on the road monitoring data, the specific location data of the meeting position of vehicles passing through the road segment within the same time period on the target road is obtained. The specific location data of the target road is analyzed sequentially on the target road to obtain the distance between the specific location of the fire truck entering the target road and the location of the fire truck entering the target road. After averaging, the nearest drivable position to the average value is located. The average meeting position on the target road is obtained sequentially. The average meeting position is different at different times.

[0024] When a fire alarm is issued, the fire truck shall enter the parking area of ​​the target road within a preset time. Where μ2 is the error value of the fire truck parked on the target road, the system determines whether the parking position of the fire truck closest to the fire warning position is on the average passing position. If so, the final parking position is determined; otherwise, the truck continues to drive. The parking command is output according to the fire truck's driving route and the final parking position.

[0025] According to the above technical solution, the management of the parking locations of subsequent arriving fire trucks corresponding to the urban fire resources, based on the most suitable driving route and the nearest parking location, after combining urban fire resources with the emergency management platform, includes:

[0026] Based on the resource scheduling priority list, available fire-fighting resources in the city are allocated. These resources include fire trucks and emergency medical personnel. The real-time location of the fire-fighting resources and their distance to the target area are calculated according to the emergency management platform. Response paths and estimated arrival times are planned, and an execution process for the dynamic resource allocation plan is established. This process includes: classifying and marking the status of all available fire-fighting resources based on the resource scheduling priority list, including the type of fire truck and the expertise of emergency medical personnel; calculating the shortest path from the current location of each fire unit to the target area; and establishing a dynamic resource allocation plan based on the shortest path.

[0027] In urban fire management, dynamic resource allocation plans are recorded, and the response status and resource configuration of fire resources are updated in real time to obtain the execution process of emergency response plans. This includes: recording the current status and specific location of all fire resources in fire management equipment; establishing an early warning database through an emergency management platform using real-time data transmission technology; updating the response status and configuration of fire resources in real time; automatically updating the database and sending the latest resource dispatch information to the emergency response team whenever the status of fire resources changes; adjusting response strategies based on real-time updated data; using data analysis tools to predict fire resource demand and dispatch efficiency; and outputting fire truck parking instructions on the target roads along several rescue routes at the fire early warning location.

[0028] According to the above technical solution, the fire truck parking management system based on emergency management includes:

[0029] The positioning module is used to filter the target road locations to be analyzed from the road monitoring data and to analyze whether fire trucks can pass through the target roads. The target road locations to be analyzed are located based on the obstacle parking data of the fire warning location.

[0030] The analysis module is used to predict the possibility of a blockage during the fire truck's entry into the target road based on the road monitoring data corresponding to the location of the target road if it is detected that the fire truck can pass through the target road, and to obtain the most suitable driving route and send it to the fire truck based on the probability prediction result.

[0031] The parking module is used to monitor the meeting position of the fire truck when it arrives at the target road along the driving route, and, in conjunction with the obtained parking position closest to the fire warning position, instruct the fire truck to park.

[0032] The allocation module is used to manage the parking locations of subsequent fire trucks corresponding to the urban fire resources, based on the most suitable driving route and the nearest parking location, after the emergency management platform is combined with urban fire resources.

[0033] According to the above technical solution, the positioning module includes:

[0034] A road segment acquisition module is used to monitor the target road, which includes both sides and the center of the road. A road plan view is obtained using map software, and the location of the target road is marked in the road plan view based on the road monitoring data. Further, the road extension position is obtained from the target road location in the road plan view towards the emergency warning location, where the emergency warning location direction is the road direction leading to the emergency warning location in the road plan view. When the road extension position is not identified in the road monitoring data, the road extension position is marked as not perpendicular to the current road, and the limit distance of the road monitoring data is set to the road segment distance that conforms to the road perpendicularity. The road width of the obtained road segment distance is K meters.

[0035] The road segment identification module is used to sequentially identify the number of obstacles appearing on the target road at L-meter intervals, count the number of marked obstacles as A, and reduce the drivable width of the target road based on the marked obstacles; it also identifies object features appearing on the target road, including: sequentially monitoring areas at L-meter intervals on the target road, and monitoring whether the area occupied by the object feature exceeds δ% of the area of ​​each L-meter interval. If it exceeds, it is marked as an obstacle; otherwise, it is marked as a non-obstacle, where δ is the minimum obstacle feature area in each L-meter interval. The proportion value; based on the marked obstacle, the database is searched for the additional driving road area required for a fire truck with an width of m meters and a length of n meters to avoid the obstacle, which is s. The additional driving road area is composed of a plane consisting of at least M meters wide and N meters long target road. The area corresponding to the additional driving road area does not completely overlap with the area corresponding to the target road area where the fire truck enters at intervals of L meters when at least one obstacle appears in each interval of L meters, where M > m, N > n. The drivable road area is compared with the driving road area; the drivable area of ​​the target road is obtained as W = AMN - x - μ1, where 1 ≤ i ≤ A, C is the area of ​​the obstacle, C i Let A be the area of ​​each obstacle on the target road, and let x be the overlapping area of ​​the additional driving road area within each L-meter interval. x is related to A. If the drivable area of ​​the road is greater than the driving area, μ1 is the error value of the drivable area of ​​the target road. Output a command indicating that the fire truck can pass through the target road; otherwise, output a command indicating that the fire truck cannot pass through the target road.

[0036] According to the above technical solution, the analysis module includes:

[0037] A traffic flow monitoring module is used to monitor the traffic flow of the target road, including: obtaining the number of vehicles Z passing through the target road through road monitoring data, wherein the number of vehicles includes vehicles passing through the target road from two opposite directions, and the detection accuracy of the vehicles is determined according to the size of the area occupied by the vehicle features in the road monitoring data.

[0038] A congestion analysis module is used to determine the likelihood of congestion occurring during the fire truck's entry into the target road. Where β is the unit conversion parameter.

[0039] According to the above technical solution, the parking module includes:

[0040] The vehicle meeting location acquisition module is used to acquire the number of vehicles passing through the road segment within a unit time period based on the traffic flow. The unit time period is set to ensure that the number of vehicles passing through the road segment within the unit time period is at least 2 and their driving directions are not the same. Based on the road monitoring data, the module acquires the specific location data of the vehicle meeting location on the target road within the same time period. The module then analyzes the specific location data of the target road sequentially on the target road to acquire the distance between the specific location of the fire truck entering the target road and the location of the fire truck entering the target road. After averaging the distances, the module locates the nearest drivable location to the average distance. The module then sequentially acquires the average vehicle meeting location on the target road. The average vehicle meeting location is different at different times.

[0041] A parking instruction output module, used to determine the parking area of ​​the fire truck on the target road within a preset time after a fire alarm is issued. Where μ2 is the error value of the fire truck parked on the target road, the system determines whether the parking position of the fire truck closest to the fire warning position is on the average passing position. If so, the final parking position is determined; otherwise, the truck continues to drive. The parking command is output according to the fire truck's driving route and the final parking position.

[0042] Compared with existing technologies, the beneficial effects achieved by this invention are as follows: This invention predicts the likelihood of congestion during the entry of fire trucks into the target road based on road monitoring data corresponding to the target road location to be analyzed, and obtains the most suitable driving route based on the probability prediction results. This greatly reduces the travel time and parking management of fire trucks and urban fire-fighting resources at the fire warning location. At the same time, during the process of fire trucks entering the target road according to the driving route, an emergency parking mechanism is set up to instruct fire trucks to park. A fire lane occupancy detection algorithm is adopted to ensure that the target lane is unobstructed within the reach of fire truck extinguishing resources. Within the limited fire lane space, this invention balances the goal of getting fire trucks as close as possible to the fire warning location and reducing the occurrence of oncoming traffic that delays the rescue speed, while also providing favorable assistance for the arrival of subsequent fire-fighting forces and providing a reference for the parking of subsequent fire trucks. This achieves overall planning for the smooth passage of fire lanes and improves the level of fire safety. Attached Figure Description

[0043] The accompanying drawings are provided to further illustrate the invention and form part of the specification. They are used in conjunction with embodiments of the invention to explain the invention and do not constitute a limitation thereof. In the drawings:

[0044] Figure 1 This is a flowchart of a fire truck parking management method based on emergency management provided by an embodiment of the present invention. Detailed Implementation

[0045] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0046] Please see Figure 1 The flowchart illustrates a fire truck parking management method based on emergency management, as provided in an embodiment of the present invention. Figure 1 It can be seen that the fire truck parking management method based on emergency management includes:

[0047] Step S1: Filter the target road locations to be analyzed from the road monitoring data, and analyze whether fire trucks can pass through the target roads. The target road locations to be analyzed are located based on the obstacle parking data of the fire warning location.

[0048] Step S2: If it is detected that the fire truck can pass through the target road, based on the road monitoring data corresponding to the location of the target road, the possibility of the fire truck encountering a blockage during its entry into the target road is predicted, and the most suitable driving route is obtained and sent to the fire truck in combination with the probability prediction result.

[0049] Step S3: As the fire truck enters the target road according to the driving route, when the fire truck reaches the meeting position on the target road, the fire truck is instructed to park based on the obtained parking position closest to the fire warning position.

[0050] Step S4: Based on the most suitable driving route and the nearest parking location, and after combining urban fire resources with the emergency management platform, manage the parking locations of subsequent arriving fire trucks corresponding to the urban fire resources.

[0051] This invention predicts the likelihood of congestion on target roads by analyzing road monitoring data corresponding to the target road location. It then uses this prediction to determine the most suitable route, significantly reducing the travel and parking time for fire trucks and urban fire resources at fire warning locations. Simultaneously, an emergency parking mechanism is implemented as fire trucks enter the target road, instructing them to park. A fire lane occupancy detection algorithm ensures unobstructed access for fire trucks within reach of fire-fighting resources. Within limited fire lane space, this approach balances proximity to fire warning locations and minimizing oncoming traffic delays, while also facilitating the arrival of subsequent fire services and providing a faster reference for subsequent fire truck parking. This comprehensive planning for smooth fire lane passage improves fire safety.

[0052] In some preferred embodiments, the obstacle deactivation data based on the fire warning location is filtered from the road monitoring data to obtain the target road location to be analyzed, including:

[0053] Step S11: Monitor the target road, which includes both sides and the center of the road. Obtain a schematic diagram of the road plan using map software, and mark the location of the target road in the schematic diagram based on the road monitoring data.

[0054] Step S12: Further obtain the road extension position from the target road location in the road plan view towards the emergency warning location, wherein the emergency warning location direction is the road direction leading to the emergency warning location in the road plan view. When the road extension position is not identified in the road monitoring data, the road extension position is marked as not conforming to the current road perpendicularity, and the limit distance of the road monitoring data is set to the road segment distance that conforms to the road perpendicularity. The road width of the road segment distance is obtained as K meters.

[0055] In a preferred embodiment, when the emergency management platform receives a fire warning, it collects the location data of the fire warning. The location data of the fire warning includes road monitoring data and obstacle parking data at the location of the fire warning. The fire warning includes all situations in which fire problems occur, including fire, explosion and other problems.

[0056] Storing historical monitoring data, and analyzing the stored historical monitoring data to identify potential safety hazards during the process of fire trucks traveling to the target road;

[0057] Based on computer vision and deep learning technologies, the system analyzes the road monitoring data in real time to detect and identify obstacles in the road, and obtains the location of the target road to be analyzed, including:

[0058] Data acquisition and preprocessing, including:

[0059] Based on the road monitoring data, the target road and all roads leading to the fire warning location are marked as specific fire lanes, and cameras installed near the fire lanes are located to obtain real-time video streams;

[0060] The video data in the real-time video stream is preprocessed, including noise reduction and frame rate adjustment, to ensure the accuracy and efficiency of obtaining the target road location that needs to be analyzed;

[0061] Obstacle feature detection and identification includes:

[0062] In the processed video frames, a convolutional neural network is used for obstacle detection. The target detection model of the convolutional neural network includes YOLO and Faster R-CNN to detect and classify objects occupying fire lanes.

[0063] Obstacle analysis and judgment include: determining whether the detected obstacles obstruct the fire lane by analyzing them;

[0064] Simultaneously, a fire lane occupancy detection algorithm is adopted. By installing cameras in the fire lanes and connecting them to a visual analysis system, the status of all fire lanes is monitored in real time. Once a fire lane is detected to be occupied, security personnel are immediately notified to handle the situation. If it is found that the security personnel are unable to clear the obstacles in the fire lane in time, a parking management method is used to ensure that the passage is unobstructed within the reach of fire trucks and fire-fighting resources. This improves the level of fire safety and enhances the efficiency and standardization of the entire management process.

[0065] In some preferred embodiments, the analysis of whether the fire truck can pass through the target road includes:

[0066] Step S13: At every L-meter interval in the target road, the number of obstacles appearing on the road is identified sequentially, and the number of marked obstacles is counted as A. Based on the marked obstacles, the drivable width of the target road is reduced on the target road.

[0067] Step S14: Identify the features of objects appearing in the target road, including:

[0068] The target road is monitored sequentially at L-meter intervals to monitor whether the area occupied by the object feature exceeds δ% of the area of ​​each L-meter interval. If it exceeds, it is marked as an obstacle; otherwise, it is marked as a non-obstacle. Here, δ is the proportion of the smallest obstacle feature in each L-meter interval.

[0069] Step S15: Based on the marked obstacles, retrieve from the database the additional driving road area s required for a fire truck with an width of m meters and a length of n meters to avoid the obstacles. The additional driving road area is a plane consisting of at least a target road with a width of M meters and a length of N meters. The fire truck can perform turning and avoidance maneuvers within the additional driving road area. The area corresponding to the additional driving road area does not completely overlap with the area corresponding to the target road area where the fire truck enters at intervals of L meters when at least one obstacle appears in each interval of L meters, i.e., MN≠LD, where M>m and N>n. Compare the drivable road area with the driving road area.

[0070] Step S16: Obtain the drivable area of ​​the target road W = AMN - x - μ1, where 1 ≤ i ≤ A, C is the area of ​​the obstacle, and C iLet A be the area of ​​each obstacle on the target road, and let x be the overlapping area of ​​the additional driving road area within each L-meter interval. x is related to A. If the drivable area of ​​the road is greater than the driving area, μ1 is the error value of the drivable area of ​​the target road, which is the actual drivable area value that cannot be included due to the driver's visual estimation error. If so, output a command indicating that the fire truck can pass the target road; otherwise, output a command indicating that the fire truck cannot pass the target road.

[0071] In some preferred embodiments, if it is detected that a fire truck can pass through the target road, based on the road monitoring data corresponding to the location of the target road to be analyzed, predicting the possibility of congestion during the fire truck's entry into the target road includes:

[0072] Step S21: Monitor traffic flow on the target road, including: obtaining the number of vehicles Z passing through the target road through road monitoring data, wherein the number of vehicles includes vehicles passing through the target road from two opposite directions, and the detection accuracy of the vehicles is determined according to the size of the area occupied by the vehicle features in the road monitoring data.

[0073] Step S22: The possibility of a blockage during the fire truck's entry into the target road. Where β is the unit transformation parameter, used to convert the obtained The unit is converted to a unitless state.

[0074] If the traffic volume on the target road is low, it means that the fire truck is less likely to encounter other vehicles when entering the target road and is more likely to be able to travel within the required road area. Conversely, if the traffic volume on the target road is high, it means that the fire truck is more likely to encounter other vehicles when entering the target road and is less likely to be able to travel within the required road area.

[0075] There is a certain degree of chance; even if the probability of a blockage during the fire truck's journey to the target road is low, it is still possible to encounter oncoming vehicles.

[0076] When a fire truck encounters an oncoming vehicle while driving, if the road on both sides is wide enough for the oncoming vehicle and the fire truck to pass simultaneously, there will be no congestion. However, if the road on both sides is not wide enough for the oncoming vehicle and the fire truck to pass simultaneously, the vehicle on one side will need to back up to a sufficiently wide road position to give way, which wastes critical rescue time. Therefore, based on reducing the likelihood of congestion when the fire truck enters the target road, the aim is to minimize the avoidance time when the fire truck encounters an oncoming vehicle in an accidental event. When the fire truck enters a congested section of the road;

[0077] In some preferred embodiments, the step of setting up an emergency parking mechanism during the process of the fire truck entering the target road according to the driving route, and monitoring the meeting position of the fire truck upon reaching the target road, and instructing the fire truck to park based on the obtained parking position closest to the fire warning location, includes:

[0078] Step S31: Based on the traffic flow, obtain the number of vehicles passing through the road segment within a unit time period. The unit time period is set to ensure that the number of vehicles passing through the road segment within the unit time period is at least 2 and their driving directions are inconsistent. Based on the road monitoring data, obtain the specific location data of the meeting positions of vehicles passing through the road segment within the same time period on the target road. Analyze the specific location data of the target road sequentially on the target road to obtain the distance between the specific location of the fire truck entering the target road and the location of the fire truck entering the target road. Calculate the average distance and locate the nearest drivable position to the average distance. Sequentially obtain the average meeting position on the target road. The average meeting position is different at different times.

[0079] Step S32: After the fire alarm is issued, the fire truck enters the parking area of ​​the target road within a preset time. Where μ2 is the error value of the fire truck parked on the target road, which is the actual area that cannot be included in the driving area due to the fire truck driver's visual error in parking the fire truck. The system determines whether the nearest parking position of the fire truck to the fire warning location is on the average passing position. If so, it is determined as the final parking position; otherwise, the vehicle continues to drive. Based on the fire truck's driving route and the final parking position, a parking command is output. The premise of the final parking position is that the fire truck can directly and effectively carry out rescue operations at the fire warning location when parked at that position.

[0080] In a preferred embodiment, a detector installed on the fire truck obtains the current driving position of the fire truck on the target road in real time, and marks the marked obstacles within F meters ahead based on the driving position, where F = GR, G is the total length of the target road, and R is the distance traveled by the fire truck into the target road obtained in real time by the detector on the fire truck.

[0081] Based on the marked position of the obstacle, determine whether a vehicle on the opposite side can enter the location before the fire truck reaches the marked position of the obstacle. When it is detected that a vehicle on the opposite side cannot reach the marked position of the obstacle before the fire truck reaches the marked position of the obstacle, issue a stop instruction to the opposite side of the target road.

[0082] In some preferred embodiments, the allocation of urban fire-fighting resources based on the driving route and parking location includes:

[0083] Step S41: Based on the resource scheduling priority list, allocate available fire-fighting resources in the city, including fire trucks and emergency personnel. Calculate the real-time location of fire-fighting resources and their distance to the target area according to the emergency management platform, plan response paths and estimated arrival times, and establish an execution process for the dynamic resource allocation plan. This includes: classifying and marking all available fire-fighting resources based on the resource scheduling priority list, including the type of fire truck (e.g., foam fire truck, water tanker, etc.) and the expertise of emergency personnel (e.g., medical rescue, fire fighting, etc.); calculating the shortest path from the current location of each fire unit to the target area; using GIS technology to ensure the accuracy of path planning; considering real-time traffic conditions and road types; adjusting the estimated arrival time to ensure optimal response speed; and combining all data to establish a dynamic resource allocation plan based on the shortest path.

[0084] Step S42: In urban fire management, record the dynamic resource allocation plan, update the response status and resource configuration of fire resources in real time, optimize the utilization of fire resources, and obtain the execution process of the emergency response plan, including: In urban fire management, maintaining and updating the dynamic resource allocation plan is crucial. Record the current status (e.g., deployed, standby, under maintenance) and specific location of all fire resources in the fire management equipment. Utilize real-time data transmission technology to ensure timely updates of information. Establish an early warning database through the emergency management platform, update the response status and configuration of fire resources in real time, and automatically update the database and send the latest resource dispatch information to the emergency response team whenever the status of fire resources changes. The emergency response team adjusts the response strategy based on the real-time updated data, uses data analysis tools to predict fire resource demand and dispatch efficiency, and outputs fire truck parking instructions on the target roads of several rescue routes at the fire early warning location.

[0085] Based on the same concept as the above embodiments, embodiments of the present invention also provide a fire truck parking management system based on emergency management, including:

[0086] The positioning module is used to filter the target road locations to be analyzed from the road monitoring data and to analyze whether fire trucks can pass through the target roads. The target road locations to be analyzed are located based on the obstacle parking data of the fire warning location.

[0087] The analysis module is used to predict the possibility of a blockage during the fire truck's entry into the target road based on the road monitoring data corresponding to the location of the target road if it is detected that the fire truck can pass through the target road, and to obtain the most suitable driving route and send it to the fire truck based on the probability prediction result.

[0088] The parking module is used to monitor the meeting position of the fire truck when it arrives at the target road along the driving route, and, in conjunction with the obtained parking position closest to the fire warning position, instruct the fire truck to park.

[0089] The allocation module is used to manage the parking locations of subsequent fire trucks corresponding to the urban fire resources, based on the most suitable driving route and the nearest parking location, after the emergency management platform is combined with urban fire resources.

[0090] In this embodiment, the positioning module includes:

[0091] A road segment acquisition module is used to monitor the target road, which includes both sides and the center of the road. A road plan view is obtained using map software, and the location of the target road is marked in the road plan view based on the road monitoring data. Further, the road extension position is obtained from the target road location in the road plan view towards the emergency warning location, where the emergency warning location direction is the road direction leading to the emergency warning location in the road plan view.
