[0002] With the continuous expansion of urban scale and the rapid growth of traffic demand, the number of vehicles has continued to grow, and the contradiction between social travel needs and the rapid operation of logistics and the smooth operation of highways has become increasingly prominent. In particular, long-term and large-scale congestion is prone to occur at various nodes on highways, which has brought tremendous pressure to highway management departments. In response to highway emergencies or congestion, the means currently adopted by highway management departments are still relatively simple. They are mainly through maintenance units patrolling on the road or observing congestion on third-party map software, and then using camera inspections to find the road conditions where emergencies or congestion occur; or after the incident occurs, the car owner asks for help and notifies the operation management unit. This method is more dependent on third-party communication software, and it takes a lot of time to find videos of congested road conditions, which makes the operation management department less efficient in solving highway emergencies.

[0045] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0046] Embodiment 1

[0047] See also Figure 1An embodiment of a method for notifying an emergency event on a highway in the present invention comprises the following steps:

[0048] S11. The mobile terminal transmits the emergency events set by the user based on the highway map to the inspection platform. The highway map includes the distribution of various sections of the highway, and the emergency events include the location where the congestion occurs;

[0049] In actual applications, highway inspection personnel can only handle roadblocks found during daily road inspections immediately, but cannot understand the on-site emergencies in real time without being on site. Therefore, the present invention adds the inspection monitoring points of highways and the distribution of various events to existing third-party maps such as Amap and Baidu Maps to form a specific highway map. Relevant personnel of the inspection management department can view the highway map in real time on a mobile terminal or on an inspection platform, and conduct online real-time inspections of the highway by viewing the dynamic information on the map.

[0050] In this embodiment, when the inspection management department personnel use the mobile terminal to view the highway map, if the map shows congestion somewhere, the management personnel can view the accident situation through the congestion distribution on the map, and report the general situation of the congestion accident on the map to the terminal page through the mobile terminal. After receiving the feedback, the terminal transmits the emergency event to the inspection platform in synchronization. The emergency event reported by the management personnel includes the general location of the congestion and its general distribution.

[0051] S12. The inspection platform retrieves the identification information of the identification device according to the congestion location in the emergency, and the identification information includes vehicle information and road condition video information;

[0052] In this embodiment, when the inspection platform receives an emergency event transmitted by a mobile terminal, it determines the approximate location of the emergency event based on the information of the emergency event, and calls up an identification device within a certain area of ​​the location. The identification device here generally refers to a camera, and then obtains the video and image information captured by the camera within the area. Using image recognition technology, it identifies the vehicle information of all vehicles in the area within a certain time range and the road condition information of the roadblock section.

[0053] It should be noted that the inspection platform synchronizes data with the mobile terminal. When the mobile terminal generates the highway map, it synchronizes the map to the inspection platform. When the inspection platform retrieves the identification information, it also synchronizes the identification information, such as the identified video or image information, to the map. In this way, users can view the video or image of a specific road section or lane on the map.

[0054] S13. The inspection platform analyzes the identification information, pushes the analysis results to the user, and determines the target event type corresponding to the emergency event based on the user's feedback;

[0055] In this embodiment, the inspection platform analyzes the identification information, pushes the analysis results to the user, and determines the target event type corresponding to the emergency event based on the user's feedback, including the following steps:

[0056] 1. The inspection platform analyzes the vehicle driving status of each lane in each road section based on the identification information, and identifies the congestion status of each road section and each lane;

[0057] The inspection platform uses image recognition technology to analyze the videos and pictures taken by the camera. It derives the vehicle driving status based on the time interval between vehicles in each lane in each road section, the distance between vehicles, and the calculated vehicle driving speed and distance, and then determines the congestion status based on the vehicle driving status.

[0058] 2. Input the congestion status of each road section and each lane into the preset emergency event recognition model to obtain the event type recognition results of each road section and each lane;

[0059] Inputting the congestion status of each road section and each lane into the model means inputting the congestion status into the preset emergency event recognition model in the form of parameters, such as the time interval between vehicles, the distance between vehicles, and the driving speed. The parameters are not limited here, and any parameters that can reflect the vehicle congestion status can be input into the model for recognition. The preset emergency event recognition model here is a model trained based on historical parameters. The model can predict the type of emergency events that occur in certain road sections and lanes based on the parameters. The recognition model is trained based on a neural network and can accurately identify the event type corresponding to the input parameters.

[0060] In addition, the congestion status of each road section and each lane is input into a preset emergency event recognition model to obtain the event type recognition results of each road section and each lane, and the following steps are also included:

[0061] (1) determining whether the congestion status of each road section and each lane meets a preset condition, and if so, inputting the recognition image information into a first preset emergency event recognition model;

[0062] (2) If not, input the recognition image information into a second preset emergency event recognition model;

[0063] (3) Determine an event type recognition result according to the recognition results of the first preset emergency event recognition model and / or the second preset emergency event recognition model.

[0064] Specifically, the preset condition refers to a threshold value set according to the congestion status parameters of each road section and each lane. For example, a threshold range is set. When the distance between at least two vehicles is less than 0, or the travel time of at least one vehicle is several times greater than the normal travel time, or the driving speed of at least one vehicle is 0, it means that a serious roadblock accident has occurred in the road section or the lane. The image information identified in the road section or the lane is input into the first preset emergency event recognition model. The first preset emergency event recognition model here is a prediction model for more serious roadblock events.

[0065] If the congestion state parameters of each road section and each lane are not within the set threshold range, it means that the roadblock event is of a generally serious type, and the recognized image information is input into the second preset emergency event recognition model.

[0066] Finally, the event type recognition result is determined based on the recognition results of the first preset emergency event recognition model and / or the second preset emergency event recognition model. It should be noted that sometimes the congestion state parameters may partially or completely meet the set threshold range. At this time, the detected road section or lane may have more serious roadblocks, or may have generally serious or less serious roadblocks. In this case, it is necessary to use two recognition models for recognition and then determine based on the comprehensive results of the two. However, in general, the recognition result is generated based on the more serious standard.

[0067] In addition, the first preset emergency event and the second preset emergency event here are prediction models set by the inspection management personnel according to the severity of the roadblock event. In actual use, other prediction models can also be set, which are not listed here. For example, the severity of vehicle stop time, vehicle reversal, traffic accident or roadblock is different, and the generated event type is also different. Setting the prediction model according to the severity level can more accurately obtain the time type corresponding to the emergency event, which can provide an accurate data basis for subsequent inspections.

[0068] 3. Push the event type identification result to the user, so that the user can combine the event type identification result with the highway map to determine the target event type corresponding to the emergency event.

[0069] Based on the event types generated above, the inspection platform pushes the event type identification results to the user. At this time, when the user receives the specific event type of congestion, he / she will combine the information displayed on the highway map to finally confirm whether to report the event type. Assuming that the user believes that the event type identified by the inspection platform is too serious, but does not actually cause such a serious accident, the user can correct the result and then upload it to the inspection platform according to the corrected event type. The inspection platform uses the identification result as the final result.

[0070] S14. The inspection platform generates an inspection alarm notification according to the target event type and pushes the inspection alarm notification to the target inspection personnel.

[0071] In this embodiment, the inspection platform generates an inspection alarm notification based on the final result, that is, the target event type, where the inspection alarm notification includes the event type, congestion location, and congested road conditions. If the inspection alarm includes at least one type, the inspection alarm priority is set. For example, the priority is set according to the degree of congestion, and more serious information is notified first.

[0072] In addition, the inspection platform generates a corresponding inspection plan based on the event type corresponding to the emergency event, and pushes the inspection plan at the same time. The inspection plan also includes inspection personnel and inspection routes, so that the management department can arrange work according to the generated inspection plan, greatly improving the efficiency of the inspection work.

[0073] Embodiment 2

[0074] See also Figure 2 In the present invention, the mobile terminal transmits the emergency event set by the user based on the highway map to the inspection platform, which also includes the following steps:

[0075] S111. The mobile terminal integrates third-party maps and establishes data links with the inspection platform;

[0076] S112. The mobile terminal obtains highway inspection information from the inspection platform, which includes the monitoring distribution of each section and the event distribution of each section;

[0077] S113. Generate a highway map by combining the third-party map with highway inspection information.

[0078] Specifically, the mobile terminal integrates a third-party map, such as Amap or Baidu Map, and dynamically displays highway information on the map in the form of dots and lines, and synchronizes the map data information to the inspection platform. After integrating the third-party map, the highway inspection information of the synchronization or inspection platform includes the monitoring distribution of each section and the event dot distribution, for example, the number and corresponding positions of the surveillance cameras set up on each section of the highway, and the distribution of the inspection personnel during the inspection. This information is added to the third-party map, and finally the third-party map is combined with the highway inspection information in the form of video or image for visualization, and finally a highway map is formed. At the same time, the mobile terminal or inspection platform receives the event data reported by the user, stores the event data persistently, classifies the events, forms event reports, and displays them on the map. In this way, by setting up the highway map, the management personnel can view the map in real time on the mobile terminal or inspection platform, understand the road condition information through the map, and do further inspection work, which effectively improves the inspection efficiency.
