Description

Technical Field

[0001] This application relates to the technical field of tunnel safety communication, and in particular to a method, system and product for integrated management of tunnel emergency telephones and broadcasts. Background Art

[0002] With the rapid development of transportation infrastructure, tunnels, as important channels connecting cities and regions, not only shorten the distance between cities but also promote economic and cultural exchanges. Their safety and emergency response capabilities have been increasingly emphasized. Due to their enclosed and special nature, once an emergency occurs in a tunnel, such as a traffic accident, fire, equipment failure, etc., it often poses a serious threat to passing vehicles and personnel.

[0003] In related technologies, if a relevant driver encounters an emergency during tunnel driving, the relevant driver usually relies on the emergency telephone installed in the tunnel to seek help. However, since there is generally a lack of effective linkage between the emergency telephone mechanism and other emergency mechanisms such as broadcast equipment, when the relevant driver dials the emergency telephone in a timely manner, the response efficiency to emergency events in the tunnel may still be reduced due to the lack of coordination among various emergency mechanisms in the tunnel. Summary of the Invention

[0004] In order to improve the response efficiency to emergency events in a tunnel, this application provides a method, system and product for integrated management of tunnel emergency telephones and broadcasts.

[0005] In a first aspect, this application provides a method for integrated management of tunnel emergency telephones and broadcasts, adopting the following technical solution: A method for integrated management of tunnel emergency telephones and broadcasts includes: Obtain emergency telephone information, where the emergency telephone information includes emergency call information and emergency site images; Identify the emergency type corresponding to the emergency telephone information, and determine whether broadcast assistance is required based on the emergency type; If so, determine the emergency area based on the emergency telephone information, and generate a broadcast prompt information and tunnel indicator light control information based on the emergency call information and the emergency area; Intervene in the emergency event occurring in the emergency area based on the tunnel indicator light control information and the broadcast prompt information.

[0006] By adopting the above technical solutions, through the analysis of emergency call information, it is convenient to understand the type, scale and location of emergency events. By judging the emergency type, it is determined whether broadcast assistance is needed, rather than broadcasting all emergency call information, which is convenient for relevant staff to give priority to dealing with emergency events that require broadcast assistance, thus improving the response efficiency to emergency events. While broadcasting a prompt in the emergency area, the tunnel indicator lights are turned on, which is convenient for further guiding the traffic flow in the tunnel, reducing chaos and the occurrence of secondary accidents, and also improving the linkage between the emergency call mechanism, the broadcast equipment mechanism and the tunnel indicator light mechanism. By adding the linkage between the emergency call mechanism and other emergency mechanisms, it is convenient to reduce information islands, thereby improving the coordination when responding to emergency events, and further improving the efficiency when responding to emergency events in the tunnel.

[0007] In a possible implementation manner, generating the broadcast prompt information based on the emergency call information and the emergency area includes: Determining the abnormal level corresponding to the emergency event based on the emergency call information, and determining at least one broadcast device to be started based on the abnormal level and the emergency area; Obtaining the simulated broadcast model corresponding to the at least one broadcast device to be started, and the personnel distribution and tunnel noise corresponding to the emergency area; Driving the simulated broadcast model based on the personnel distribution and tunnel noise to determine the broadcast coverage area; Judging whether the broadcast coverage area can cover the emergency area. If not, adjust the original broadcast power of each broadcast device to be started until the updated broadcast coverage area can cover the emergency area. The updated broadcast coverage area is obtained by driving the simulated broadcast model based on the adjusted broadcast power; Generating the broadcast prompt information based on each broadcast device to be started and the adjusted broadcast power of each broadcast device to be started.

[0008] By adopting the above technical solutions, determining the broadcast devices to be started based on the abnormal level and the emergency area avoids the waste of broadcast resources and ensures that the broadcast prompt information can be conveyed to relevant personnel in the most effective way. By comprehensively considering the personnel distribution and tunnel noise in the emergency area, it is convenient to more accurately evaluate the reachability and effectiveness of the broadcast prompt information. When the simulation result shows that the broadcast coverage area cannot completely cover the emergency area, the original broadcast power of each broadcast device to be started is automatically adjusted to update the broadcast coverage area to ensure that the updated broadcast coverage area can completely cover the emergency area, thus improving the transmission efficiency of the broadcast prompt information.

[0009] In a possible implementation manner, it further includes: If there is a tangent broadcast coverage area, determine whether the tangent coverage point is the emergency center point of the emergency area; If so, it is necessary to adjust the broadcast power of the tangent broadcast coverage area corresponding to the to-be-activated broadcast until the area of the coverage intersection area is not lower than a preset area threshold, and the preset area threshold is determined by the abnormal level of the emergency area and the tunnel noise.

[0010] By adopting the above technical solution, by comparing the tangent coverage point with the emergency center point of the emergency area, it is convenient to evaluate whether the broadcast prompt information can be effectively transmitted to the core area of the emergency area. Due to the complex environment of the tunnel, the broadcast signal may be attenuated during transmission or blocked by obstacles. Therefore, when the tangent coverage point is the emergency center point, at least two to-be-activated broadcast devices are required to form a sufficient coverage intersection area to better adapt to the complex environment in the tunnel, so as to ensure that the broadcast prompt information can be fully transmitted in the emergency area.

[0011] In a possible implementation manner, generating tunnel indicator light control information based on the emergency area includes: Determining at least one evacuation passage opening based on the emergency area and the abnormal level corresponding to the emergency event; Based on the relative positions between the emergency area and each evacuation passage opening, determining the route indicator light control information for each evacuation route corresponding to each evacuation passage opening, and the route indicator light control information is used to control the tunnel indicator lights corresponding to each evacuation route; Based on the abnormal level of the emergency event, determining the passage opening indicator light control information corresponding to each evacuation passage opening, and the passage opening indicator light control information is used to control the tunnel indicator lights arranged at each evacuation passage opening; Generating the tunnel indicator light control information based on the route indicator light control information and the passage opening indicator light control information.

[0012] By adopting the above technical solution, by comprehensively considering the emergency area and the abnormal level of the emergency event to determine at least one evacuation passage opening, it is convenient to ensure the smoothness of the relevant personnel during the evacuation process in the emergency area. In addition, through the route indicator light control information and the passage opening indicator light control information, it is convenient to accurately indicate the evacuation direction, so that the relevant personnel can quickly find and evacuate along the correct evacuation route, which helps to avoid getting lost or going the wrong way in an emergency, and also helps to avoid dangerous situations such as congestion and trampling during the evacuation process, and is convenient to improve the safety of the evacuation process.

[0013] In a possible implementation manner, it further includes: Obtain a real-time tunnel image. When the real-time tunnel image contains preset event features, identify the influence trajectory of the preset event features within a first preset time period; Based on the influence trajectory, determine the predicted influence area corresponding to the preset event features within a second preset time period; Based on the preset event features, determine the broadcast prompt content, and through the broadcast device corresponding to the predicted influence area, broadcast the broadcast prompt content in a targeted manner.

[0014] By adopting the above technical solution, by monitoring the internal situation of the tunnel in real time, it is convenient to timely discover abnormal situations in the tunnel. After determining the broadcast prompt content according to the preset event features and the predicted influence area, the predicted influence area is broadcast in a targeted manner through the broadcast device corresponding to the predicted influence area to remind relevant drivers within the predicted influence area. The targeted broadcast not only facilitates improving the pertinence and effectiveness of the broadcast prompt information, but also facilitates avoiding unnecessary interference.

[0015] In a possible implementation manner, it further includes: Light up the analog phone indicator corresponding to the emergency phone information from the virtual panel. The virtual panel contains analog phone indicators corresponding to all emergency phones in the tunnel to be managed; Based on the abnormal level of the emergency event corresponding to the emergency phone, determine the flashing information. The flashing information includes the flashing duration and the flashing frequency; When the abnormal level is higher than the preset level, based on the flashing position of the analog phone indicator in the virtual panel, determine the indication and guidance information. The indication and guidance information includes the indication and guidance shape and the indication and guidance direction; Control the virtual panel based on the flashing information and the indication and guidance information.

[0016] By adopting the above technical solution, by checking the flashing situation of the analog phone indicators in the virtual panel, it is convenient to intuitively understand the abnormal level of the emergency events in the emergency area. And when the abnormal level is relatively high, the indication and guidance shape and the indication and guidance direction of other analog phone indicators in the virtual panel can also be adjusted to enhance the visual feedback effect. This intuitive visual feedback is convenient to immediately attract the attention of relevant management personnel, so that relevant management personnel can quickly locate the emergency phone and take corresponding countermeasures in a timely manner, thus facilitating improving the response efficiency of emergency events.

[0017] In a second aspect, the present application provides a management system, adopting the following technical solution: A management system, the management system includes: At least one processor; A memory; At least one application program, wherein the at least one application program is stored in a memory and configured to be executed by at least one processor, and the at least one application program is configured to: execute the above-mentioned integrated management method for tunnel emergency telephones and broadcasts.

[0018] In a third aspect, the present application provides a computer-readable storage medium, adopting the following technical solution: A computer-readable storage medium, including: a computer program capable of being loaded and executed by a processor to execute the above-mentioned integrated management method for tunnel emergency telephones and broadcasts.

[0019] In a fourth aspect, the present application provides a computer program product, adopting the following technical solution: A computer program product, including a computer program, wherein when the computer program is executed by a processor, it implements the above-mentioned integrated management method for tunnel emergency telephones and broadcasts.

[0020] In summary, the present application includes at least one of the following beneficial technical effects: By analyzing the emergency telephone information, it is convenient to understand the type, scale, and location of emergency events. By judging the emergency type, it is determined whether broadcast assistance is required, rather than broadcasting all emergency telephone information. This facilitates relevant staff to prioritize the handling of emergency events that require broadcast assistance, thereby improving the response efficiency to emergency events. While broadcasting a prompt in the emergency area, the tunnel indicator lights are turned on, which is convenient for further guiding the traffic flow in the tunnel, reducing chaos and the occurrence of secondary accidents. It also improves the linkage between the emergency telephone mechanism, the broadcast device mechanism, and the tunnel indicator light mechanism. By adding the linkage between the emergency telephone mechanism and other emergency mechanisms, it is convenient to reduce information islands, thereby improving the coordination when responding to emergency events, and further improving the efficiency of responding to emergency events in the tunnel.

[0021] By comparing the tangent coverage point with the emergency center point of the emergency area, it is convenient to evaluate whether the broadcast prompt information can be effectively conveyed to the core area of the emergency area. Due to the complex environment of the tunnel, the broadcast signal may be attenuated during transmission or blocked by obstacles. Therefore, when the tangent coverage point is the emergency center point, at least two broadcast devices to be started are required to form a sufficient coverage intersection area to better adapt to the complex environment in the tunnel, so as to ensure that the broadcast prompt information can be fully conveyed in the emergency area.

Apparently, the described embodiments are some, but not all, of the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative efforts fall within the scope of protection of the present application.

[0026] It should be noted that in the alternative embodiments of the present application, for relevant data such as object information, when the embodiments in the present application are applied to specific products or technologies, object permission or consent needs to be obtained, and the collection, use, and processing of relevant data need to comply with the relevant laws, regulations, and standards of relevant countries and regions.

[0027] Specifically, the embodiments of the present application provide a method for integrated management of tunnel emergency telephones and broadcasts, which is executed by a management system. The management system can be a server or a terminal device. Among them, the server can be an independent physical server, a server cluster or a distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smart phone, a tablet computer, a notebook computer, a desktop computer, etc., but is not limited thereto. The terminal device and the server can be directly or indirectly connected through wired or wireless communication methods, and the embodiments of the present application do not limit this here.

[0028] Refer to Figure 1 ,Figure 1 It is a schematic flowchart of a method for integrated management of tunnel emergency telephones and broadcasts in an embodiment of the present application. The method includes steps S110 - S140, where: Step S110: Obtain emergency telephone information, which includes emergency call information and emergency site images.

[0029] Specifically, emergency telephones are distributed on both sides of the tunnel to be managed for use by personnel passing through the tunnel to be managed. When relevant drivers encounter emergencies in the tunnel to be managed, they can press the button on the emergency telephone terminal nearby to send a call request to contact external rescue agencies. The emergency telephone information is formed after the emergency telephone is dialed. The emergency call information mainly includes the description of the emergency situation by relevant drivers. Communication cables can be used for communication between the emergency telephone and the management system. The communication cables in the embodiments of the present application are shielded twisted pairs, which are convenient for effectively resisting electromagnetic interference and improving data transmission quality. The call location can be located first according to the call request, and then the emergency site image can be obtained from the image acquisition device corresponding to the call location.

[0030] Step S120: Identify the emergency type corresponding to the emergency telephone information, and determine whether broadcast assistance is required based on the emergency type.

[0031] Specifically, when the emergency type is a preset emergency type, it can be determined that current broadcast assistance is required. The preset emergency types include but are not limited to traffic accidents, fires, equipment failures, and natural disasters. For example, when a traffic accident occurs in the tunnel, especially an accident involving multiple vehicles or causing traffic interruption, it is necessary to immediately release emergency information to relevant personnel in the tunnel through the broadcast device to remind relevant personnel to pay attention to the road conditions ahead and take evasive measures to avoid the occurrence of secondary accidents. Different preset emergency types have different emergency characteristics, and there is a characteristic mapping relationship between the preset emergency types and the emergency characteristics. Based on this characteristic mapping relationship, the preset emergency type corresponding to any emergency characteristic can be determined. For example, when the emergency call information of the emergency telephone information contains feature a, or the emergency site image contains feature b, it can be determined that the emergency characteristic corresponding to the emergency telephone information is a fire. The specific content of this characteristic mapping relationship is not specifically limited in the embodiments of the present application and can be determined by relevant staff according to historical experimental data and then uploaded to the management system. The emergency type corresponding to the emergency telephone information can be determined based on a preset feature recognition algorithm. The specific preset feature recognition algorithm is not specifically limited in the embodiments of the present application.

[0032] Step S130: If so, determine the emergency area based on the emergency telephone information, and generate a broadcast prompt information and tunnel indicator light control information based on the emergency call information and the emergency area.

[0033] Specifically, when the emergency type is a preset emergency type, it indicates that relevant broadcast devices in the tunnel need to be activated. Generally, the broadcast devices are installed in different areas inside the tunnel to be managed according to a preset layout to ensure that the broadcast sound can cover the entire tunnel to be managed. At the same time, due to the complex internal environment of the tunnel, the broadcast signal may attenuate during transmission. Therefore, a power amplifier is generally installed in the machine room near the entrance of the tunnel to be managed to enhance the broadcast signal strength and enable it to maintain a high auditory effect during long-distance transmission. Except for the power amplifier, most of the other components can be flexibly replaced according to the actual application scenario. For example, the number and spacing of the broadcast devices can be adjusted according to the tunnel length to achieve the best sound propagation effect; the number of emergency telephones can also be increased or decreased as the case may be to better serve pedestrians. Considering the special conditions in some areas, such as unstable geological conditions may lead to unstable power supply, in the embodiments of the present application, a dual power supply method of solar energy and the power grid is adopted to supply power to the emergency telephones and broadcast devices. In this way, it is convenient to reduce energy waste and avoid risks such as communication interruption caused by power outages, thereby further enhancing the robustness of the management system.

[0034] The emergency area is the area where an emergency event occurs. The emergency location can be determined based on the surrounding tunnel features provided by relevant drivers in the emergency call information, or tunnel section signs, etc. Then, based on the emergency location, the emergency area is located in the emergency scene image. For example, when the emergency event is a car accident, the emergency area may include the accident occurrence point, the vehicle damage area, the casualty area, and the traffic jam area; when the emergency event is a vehicle fire, the emergency area may be the area including the burning vehicle and the traffic jam area caused by the burning vehicle, etc. Different emergency events have different methods for determining the emergency area. After determining the emergency event, the method for determining the emergency area corresponding to different emergency events can be determined according to the mapping relationship between the emergency event and the preset determination strategy. Among them, the mapping relationship of the preset determination strategy includes the method for determining the emergency area corresponding to each emergency event, and the specific content is not specifically limited in the embodiments of the present application and can be determined by relevant staff based on historical experimental data and then uploaded to the management system.

[0035] After determining the emergency area, it is necessary to adjust the indicator lights and broadcast devices in the tunnel to be managed according to the emergency area. By turning on the indicator lights in the tunnel, it is convenient to provide a clear evacuation route or avoidance route for relevant drivers or other people affected by the emergency event, reducing the risk of secondary accidents. In addition, by turning on the broadcast devices in the tunnel, an emergency notice can be quickly issued to relevant drivers or other affected people, informing them of information such as the specific location of the emergency event, the evacuation route, and the rescue measures, guiding relevant people to evacuate in an orderly manner and avoiding secondary injuries. The generated broadcast prompt information is used to control the broadcast devices in the tunnel for broadcasting, and the generated tunnel indicator light control information is used to control the indicator lights in the tunnel for lighting.

[0036] Step S140: Based on the tunnel indicator control information and the broadcast prompt information, intervene in the emergency events occurring in the emergency area.

[0037] Specifically, the broadcast device, the emergency phone, and the indicator light are organically combined and can share the same console, so that the broadcast device, the emergency phone, and the indicator light can be uniformly controlled and managed, without the need to operate multiple systems separately, simplifying the operation process. Using the same communication cable for signal transmission reduces the number and complexity of communication cables, and reduces the construction and maintenance costs. In addition, through this organic combination method, it is convenient to ensure that the information between emergency devices such as the broadcast device, the emergency phone, and the indicator light can be shared in real time, which is convenient to improve the communication efficiency between emergency devices. After an emergency occurs, information can be quickly conveyed through the emergency phone and broadcast to relevant personnel in a timely manner through the broadcast device. At the same time, the indicator light provides visual indication, jointly forming a rapid response mechanism.

[0038] For the embodiments of the present application, by analyzing the emergency phone information, it is convenient to understand the type, scale, and location of the emergency event. By judging the emergency type, it is determined whether broadcast assistance is required, rather than broadcasting all emergency phone information, which is convenient for relevant staff to give priority to dealing with emergency events that require broadcast assistance, thus facilitating the improvement of the response efficiency to emergency events. When broadcasting a prompt in the emergency area, the tunnel indicator light is turned on, which is convenient to further guide the traffic flow in the tunnel, reduce chaos and the occurrence of secondary accidents, and also facilitate the improvement of the linkage between the emergency phone mechanism, the broadcast device mechanism, and the tunnel indicator light mechanism. By adding the linkage between the emergency phone mechanism and other emergency mechanisms, it is convenient to reduce information islands, thereby improving the coordination when responding to emergency events, and further facilitating the improvement of the efficiency when responding to emergency events in the tunnel.

[0039] Furthermore, in order to improve the propagation efficiency of the broadcast prompt information, in the embodiments of the present application, the broadcast prompt information is generated based on the emergency call information and the emergency area, and specifically may include: Determine the abnormal level corresponding to the emergency event based on the emergency call information, and determine at least one broadcast device to be started based on the abnormal level and the emergency area; obtain the analog broadcast model corresponding to at least one broadcast device to be started, the personnel distribution and tunnel noise corresponding to the emergency area; drive the analog broadcast model based on the personnel distribution and tunnel noise to determine the broadcast coverage area; determine whether the broadcast coverage area can cover the emergency area, if not, adjust the original broadcast power of each broadcast device to be started until the updated broadcast coverage area can cover the emergency area, and the updated broadcast coverage area is obtained by driving the analog broadcast model based on the adjusted broadcast power; generate a broadcast prompt message based on each broadcast device to be started and the adjusted broadcast power of each broadcast device to be started.

[0040] Specifically, when it is necessary to generate a broadcast prompt message, the emergency type representing the emergency event is a preset emergency type, that is, it may be one of traffic accidents, fires, equipment failures, and natural disasters. The first abnormal scores corresponding to different preset emergency types are different. The first abnormal score corresponding to the preset emergency type of the emergency event can be determined based on the preset first score mapping relationship. The preset first score mapping relationship includes the first abnormal scores corresponding to different preset emergency types. Then, based on the affected area of the emergency area and the preset second score mapping relationship, the second abnormal score corresponding to the emergency area of the emergency event is determined. The preset second score mapping relationship is the corresponding relationship between the affected area and the second abnormal score. Calculate the sum of the first abnormal score and the second abnormal score corresponding to the emergency event to determine the total abnormal score. Finally, based on the preset level mapping relationship, determine the abnormal level corresponding to the total abnormal score. Among them, the specific contents of the preset first score mapping relationship, the preset second score mapping relationship, and the preset level mapping relationship are not specifically limited in the embodiments of the present application and can be determined by relevant staff according to historical experimental data and then uploaded to the management system.

[0041] The higher the abnormal level, the more broadcast devices to be started. There is a corresponding relationship between the abnormal level and the number of devices. Based on this corresponding relationship, the number of broadcast devices to be started corresponding to any abnormal level can be determined. After determining the number of broadcast devices to be started, regarding the emergency area as the center, the specific broadcast devices to be started can be determined in turn. After determining the specific broadcast devices to be started, the broadcast is not directly turned on, but it is necessary to first simulate the broadcast coverage of the broadcast devices to be started to predict or evaluate the propagation of the broadcast signal in the actual tunnel environment, including the coverage range, intensity, and possible blind spots of the broadcast signal.

[0042] In a pairwise simulation method, the broadcast coverage areas corresponding to two adjacent broadcast devices to be started are simulated in sequence. Finally, by comparing the relationship between the overall broadcast coverage area corresponding to all broadcast devices to be started and the emergency area, it is decided whether to adjust the original broadcast power of the broadcast devices to be started. For any group of adjacent broadcast devices to be started, the simulated broadcast models of each broadcast device to be started can be obtained. After driving the simulated broadcast models of adjacent broadcast devices to be started based on the personnel distribution and tunnel noise in the corresponding part of the emergency area, the real broadcast effect in the tunnel after the adjacent two broadcast devices to be started are turned on can be simulated. The corresponding part of the emergency area for two adjacent broadcast devices to be started is the emergency area located between the two adjacent broadcast devices to be started. Since the personnel distribution in the tunnel may affect the broadcast effect, in addition, since vehicle driving, mechanical operation, etc. in the tunnel will generate noise, the tunnel noise may interfere with the transmission and reception of broadcast signals, which may also affect the broadcast effect. Therefore, it is crucial to refer to the personnel distribution and tunnel noise when simulating the real broadcast effect. The personnel distribution can be located by detecting the emergency scene image. Specifically, the personnel in the emergency scene image can be detected through a preset personnel feature recognition algorithm, including the number of personnel and their positions. The specific preset personnel feature recognition algorithm is not specifically limited in the embodiments of the present application. After the tunnel noise is collected by the noise monitoring device set in the tunnel to be managed, the collected tunnel noise is uploaded to the management system. The noise monitoring device can be a noise meter, a sound level meter, etc. If the simulation result shows that the broadcast coverage areas of two adjacent broadcast devices to be started can cover the corresponding part of the emergency area, there is no need to adjust the broadcast power of the two adjacent broadcast devices to be started at this time, that is, control the two adjacent broadcast devices to be started to broadcast according to the original broadcast power. If the simulation result shows that the broadcast coverage area cannot cover the corresponding part of the emergency area, the broadcast power of the two adjacent broadcast devices to be started needs to be adjusted at this time, that is, the broadcast power needs to be increased on the basis of the original broadcast power. The specific power increase value is not specifically limited in the embodiments of the present application, as long as the broadcast coverage area generated when the two adjacent broadcast devices to be started broadcast according to the adjusted broadcast power can cover the corresponding part of the emergency area.

[0043] By using the above method, the broadcast power of each broadcast device to be started can be evaluated or adjusted. Since the installation positions of each broadcast device to be started are different, when predicting or evaluating the broadcast coverage areas generated by the broadcast devices to be started at different positions, the personnel distribution and tunnel noise are different. Therefore, the power increase values corresponding to different broadcast devices to be started when the original broadcast power needs to be adjusted are also different. Finally, based on each broadcast device to be started and the adjusted broadcast power of each broadcast device to be started, a broadcast prompt message is generated, thereby improving the transmission efficiency of the broadcast prompt message.

[0044] Further, to ensure that the broadcast prompt information can be fully conveyed in the emergency area, the method provided by the embodiment of the present application further includes step S210 and step S220, as Figure 2 shown, where: Step S210: If there is a tangent broadcast coverage area, determine whether the tangent coverage point is the emergency center point of the emergency area.

[0045] Specifically, the tangent broadcast coverage area means that the partial broadcast coverage areas corresponding to two adjacent to-be-activated broadcast devices are tangent to each other. If it is detected that the partial broadcast coverage areas corresponding to two adjacent to-be-activated broadcast devices are tangent broadcast coverage areas, at this time, it is necessary to determine whether the tangent coverage point of the partial broadcast coverage areas of the two adjacent to-be-activated broadcast devices is the emergency center point of the emergency area. When the tangent coverage point is the emergency center point, even if the broadcast coverage areas corresponding to the two adjacent to-be-activated broadcast devices can cover the corresponding partial emergency areas, it is still necessary to adjust the broadcast power of the two adjacent to-be-activated broadcast devices. Due to the complex environment of the tunnel, the broadcast signal may be attenuated during transmission or blocked by obstacles. Therefore, to ensure that relevant drivers or other affected persons located at the center of the emergency area can accurately receive the broadcast content.

[0046] Step S220: If so, it is necessary to adjust the broadcast power of the to-be-activated broadcast corresponding to the tangent broadcast coverage area until the area of the corresponding area of the coverage intersection area is not lower than the preset area threshold, and the preset area threshold is determined by the abnormal level of the emergency area and the tunnel noise.

[0047] Specifically, when the partial broadcast coverage areas corresponding to two adjacent to-be-activated broadcast devices are tangent to each other, it is necessary to further adjust the broadcast power of the two adjacent to-be-activated broadcast devices until there is an intersection in the partial broadcast coverage areas corresponding to the two adjacent to-be-activated broadcast devices, as Figure 3 shown. After adjusting the broadcast power of the to-be-activated broadcast device 1 and the to-be-activated broadcast device 2, the partial broadcast coverage areas of the to-be-activated broadcast device 1 and the to-be-activated broadcast device 2 change from the original tangent state to an intersection state.

[0048] However, it is not enough that there is an intersection in the partial broadcast coverage areas corresponding to two adjacent to-be-activated broadcast devices. Instead, it is necessary to determine the minimum value of the area of the coverage intersection area according to the abnormal level of the emergency area and the tunnel noise. Different combinations of abnormal levels and tunnel noises correspond to different preset area thresholds, which can be specifically determined through a preset threshold mapping relationship. The preset threshold mapping relationship is the corresponding relationship between different combinations of abnormal levels and tunnel noises and the preset area thresholds. The specific content of this preset threshold mapping relationship is not specifically limited in the embodiment of the present application.

[0049] For the embodiments of the present application, by comparing the tangent coverage points with the emergency center points of the emergency areas, it is convenient to evaluate whether the broadcast prompt information can be effectively transmitted to the core areas of the emergency areas. Due to the complex environment of the tunnel, the broadcast signal may be attenuated during transmission or blocked by obstacles. Therefore, when the tangent coverage point is the emergency center point, at least two broadcast devices to be activated are required to form a sufficient coverage intersection area to better adapt to the complex environment in the tunnel.

[0050] Furthermore, in order to improve the safety during the evacuation process and avoid getting lost or taking the wrong route in case of an emergency, tunnel indicator control information is generated based on the emergency area, specifically including: Determining at least one evacuation passageway based on the emergency area and the abnormal level corresponding to the emergency event; determining the route indicator control information for the evacuation route corresponding to each evacuation passageway based on the relative positions between the emergency area and each evacuation passageway, where the route indicator control information is used to control the tunnel indicators corresponding to each evacuation route; determining the passageway indicator control information corresponding to each evacuation passageway based on the abnormal level of the emergency event, where the passageway indicator control information is used to control the tunnel indicators set at each evacuation passageway; generating the tunnel indicator control information based on the route indicator control information and the passageway indicator control information.

[0051] Specifically, the number of evacuation passageways corresponding to the abnormal level can be determined first according to the preset passageway mapping relationship, and then the corresponding number of evacuation passageways can be selected from the emergency area or the adjacent areas of the emergency area. The preset passageway mapping relationship is the corresponding relationship between the abnormal level and the number of evacuation passageways. The specific content of the preset passageway mapping relationship is not specifically limited in the embodiments of the present application and can be determined by relevant staff according to historical experimental data and then uploaded to the management system.

[0052] Since the evacuation passageways may be located on both sides of the emergency area or on both sides of the adjacent areas corresponding to the emergency area, it is necessary to determine the evacuation route corresponding to each evacuation passageway based on the relative positions between the emergency area and each evacuation passageway, and then determine the lighting color and lighting frequency of each tunnel indicator in the evacuation route. The route indicator control information in the present application does not directly turn on all the tunnel indicators on the evacuation route, but forms evacuation indication arrows or signs based on the direction of the evacuation passageway. In addition to lighting the tunnel indicators, it also clarifies the evacuation direction for the evacuees. The specific lighting color and evacuation indication signs are not specifically limited in the embodiments of the present application. The route indicator control information corresponding to each evacuation route can be determined based on the above method.

[0053] In addition to the tunnel indicator lights corresponding to the evacuation routes being lit, tunnel indicator lights are also installed above each evacuation passage entrance. The flashing frequency of the tunnel indicator lights above the evacuation passage entrances needs to be determined according to the anomaly level of the emergency area. The higher the anomaly level, the higher the flashing frequency of the corresponding tunnel indicator lights. Finally, based on the route indicator light control information and the passage entrance indicator light control information, the tunnel indicator lights in the evacuation routes and the tunnel indicator lights installed at the evacuation passage entrances are controlled respectively, so that relevant personnel can quickly find and evacuate along the correct evacuation route.

[0054] Furthermore, the method provided by the embodiments of the present application further includes: Obtain real-time tunnel images. When the real-time tunnel images contain preset event features, identify the influence trajectory of the preset event features within the first preset time period; determine the predicted influence area corresponding to the preset event features within the second preset time period based on the influence trajectory; determine the broadcast prompt content based on the preset event features, and conduct directional broadcasting of the broadcast prompt content through the broadcast devices corresponding to the predicted influence area.

[0055] Specifically, the method provided by the embodiments of the present application can not only link other emergency devices such as broadcast devices and indicator light devices after receiving an emergency call, but also can timely discover possible abnormal events in the tunnel to be managed by monitoring real-time tunnel images. The real-time tunnel images can be collected by image acquisition devices installed in the tunnel to be managed and uploaded to the management system in real time. A preset feature recognition algorithm can be used to detect whether the real-time tunnel images contain preset event features. The preset event features can be that the vehicle deviates from the lane, the vehicle speed is unstable, etc. Among them, according to the extracted lane features and vehicle features, it can be judged whether the vehicle deviates from the lane. Specifically, a certain deviation threshold can also be set. For example, if the distance between the vehicle and the lane line exceeds the deviation threshold, it is considered that the vehicle deviates from the lane. The position of the vehicle in the real-time tunnel images can be detected through a target detection algorithm, and the position information of the vehicle at different time points can be recorded to judge whether the vehicle has an unstable vehicle speed.

[0056] When it is detected that the real-time tunnel images contain preset event features, the vehicle containing the preset event features is determined as a potential hazard vehicle, and the influence trajectory of the potential hazard vehicle within the first preset time period is recorded based on the preset event features. The first preset time period is a period of time after the potential hazard vehicle is determined. The duration corresponding to the first preset time period can be 1 minute or 2 minutes. The specific duration is not specifically limited in the embodiments of the present application.

[0057] Based on the influence trajectory and the time length of the second preset time period, a prediction algorithm is used to predict the area that the potential hazard vehicle may affect within the second preset time period. The prediction algorithm can be a linear prediction, a machine learning model, etc. The specific prediction algorithm is not specifically limited in the embodiments of the present application. The predicted affected area can be one or more polygonal or circular areas that cover the driving path of the potential hazard vehicle within the second preset time period. Different preset event characteristics correspond to different broadcast prompt contents. The predicted affected area is directionally broadcast through the corresponding broadcast device of the predicted affected area to provide directional reminders to relevant drivers within the predicted affected area. If the driver corresponding to the potential hazard vehicle cannot adjust the driving state in time, the relevant drivers within the predicted affected area can be reminded to avoid in advance through the directional reminder, so as to avoid collisions with the potential hazard vehicle. In addition, directional broadcasting not only facilitates improving the pertinence and effectiveness of the broadcast prompt information, but also helps to avoid unnecessary interference.

[0058] To facilitate the relevant management personnel to quickly locate the emergency call and take corresponding countermeasures in time, the method provided in the embodiments of the present application further includes: Light the simulated phone indicator corresponding to the emergency call information from the virtual panel. The virtual panel contains the simulated phone indicators corresponding to all the emergency calls in the tunnel to be managed; determine the flashing information based on the abnormal level of the emergency event corresponding to the emergency call. The flashing information includes the flashing duration and the flashing frequency; when the abnormal level is higher than the preset level, determine the indication guidance information based on the flashing position of the simulated phone indicator in the virtual panel. The indication guidance information includes the indication guidance shape and the indication guidance direction; control the virtual panel based on the flashing information and the indication guidance information.

[0059] Specifically, the virtual panel can be set on the console. The virtual panel contains the simulated phone indicators corresponding to each emergency call in the tunnel to be managed. When an emergency occurs in the tunnel, the relevant driver will press the button on the nearest emergency call to contact the external rescue agency. At this time, the console will immediately identify the call request from which location and transfer it to the designated staff for answering. At the same time, the corresponding indicator light on the virtual panel on the console will be lit. Different abnormal levels correspond to different flashing information. The higher the abnormal level, the longer the flashing duration and the faster the flashing frequency. The flashing information corresponding to different abnormal levels can be determined based on the preset flashing mapping relationship. The preset flashing mapping relationship is the corresponding relationship between the abnormal level and the flashing information.

[0060] Since the virtual panel contains the analog phone indicators corresponding to all the emergency phones in the tunnel to be managed, there may be more than one analog phone indicator lit within the same time period. At this time, the lighting mode of the virtual panel can be adjusted according to the anomaly level of the emergency event corresponding to each emergency phone. When the anomaly level is high, by adjusting the lighting mode of other analog phone indicators in the virtual panel, the attention of relevant management personnel to the analog phone indicator with a high anomaly level can be enhanced. When the anomaly level of the analog phone indicator is higher than the preset level, the indicatable area and the indication and guidance information are determined based on the flashing position of the analog phone indicator in the virtual panel, and then the indication and guidance shape is displayed in the indicatable area of the virtual panel according to the indication and guidance direction. The indication and guidance shape can be an arrow or any other symbol that can represent the direction, and the indication and guidance direction is the direction pointing to the analog phone indicator. When the anomaly level is high, by adjusting the indication and guidance shape and the indication and guidance direction of other analog phone indicators in the virtual panel, the visual feedback effect is enhanced, so that relevant management personnel can quickly locate the emergency phone and take corresponding countermeasures in time.
