Description

Technical Field

[0001] This application relates to the field of tunnel safety communication technology, and in particular to a method, system and product for integrated management of tunnel emergency telephone and broadcast. Background Technology

[0002] With the rapid development of transportation infrastructure, tunnels, as vital channels connecting cities and regions, not only shorten distances between cities but also promote economic and cultural exchange. Their safety and emergency response capabilities are receiving increasing attention. Due to their enclosed and unique nature, tunnels often pose a serious threat to passing vehicles and personnel in the event of emergencies such as traffic accidents, fires, or equipment malfunctions.

[0003] In related technologies, if drivers encounter an emergency while driving in a tunnel, they usually rely on the emergency telephone installed in the tunnel to seek help. However, due to the lack of effective coordination between the emergency telephone mechanism and other emergency mechanisms such as broadcasting equipment, even if drivers dial the emergency telephone in time, the lack of coordination among the various emergency mechanisms in the tunnel may lead to a decrease in the efficiency of responding to emergencies in the tunnel. Summary of the Invention

[0004] To improve the efficiency of response to emergencies in tunnels, this application provides a method, system, and product for integrated management of tunnel emergency telephone and broadcast systems.

[0005] Firstly, this application provides an integrated management method for emergency telephone and broadcast systems in tunnels, employing the following technical solution:

[0006] A method for integrated management of emergency telephone and broadcast systems in tunnels includes:

[0007] Obtain emergency call information, which includes emergency call information and emergency scene images;

[0008] Identify the emergency type corresponding to the emergency call information, and determine whether broadcast assistance is needed based on the emergency type;

[0009] If so, the emergency area is determined based on the emergency call information, and broadcast prompts and tunnel indicator light control information are generated based on the emergency call information and the emergency area.

[0010] Based on the tunnel indicator light control information and the broadcast prompt information, intervention is carried out on emergency events occurring in the emergency area.

[0011] By adopting the above technical solution and analyzing emergency call information, it is easier to understand the type, scale, and location of emergency events. The system determines whether broadcast assistance is needed based on the type of emergency, rather than broadcasting all emergency calls. This allows relevant personnel to prioritize emergency events requiring broadcast assistance, thereby improving response efficiency. Simultaneously broadcasting alerts to emergency areas and activating tunnel indicator lights further guides traffic flow within the tunnel, reducing chaos and secondary accidents. It also enhances the linkage between the emergency call mechanism, broadcast equipment, and tunnel indicator light mechanism. By adding linkage between the emergency call mechanism and other emergency mechanisms, information silos are reduced, improving coordination in emergency response and ultimately increasing efficiency in responding to emergencies within the tunnel.

[0012] In one possible implementation, generating broadcast notification information based on the emergency call information and the emergency area includes:

[0013] Based on the emergency call information, the level of abnormality corresponding to the emergency event is determined, and based on the level of abnormality and the emergency area, at least one broadcast device to be activated is identified.

[0014] Obtain the simulated broadcast model corresponding to the at least one broadcast device to be activated, and the personnel distribution and tunnel noise corresponding to the emergency area;

[0015] The simulated broadcast model is driven by the personnel distribution and tunnel noise to determine the broadcast coverage area;

[0016] 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. The updated broadcast coverage area is obtained based on the adjusted broadcast power driving the simulated broadcast model.

[0017] A broadcast prompt message is generated based on each broadcast device to be started and the adjusted broadcast power of each broadcast device to be started.

[0018] By adopting the above technical solution, the broadcasting equipment that needs to be activated is determined based on the anomaly level and emergency area, avoiding the waste of broadcasting resources and ensuring that broadcasting information can be conveyed to relevant personnel in the most effective way. By comprehensively considering the distribution of people in the emergency area and tunnel noise, it is easier to more accurately assess the accessibility and effectiveness of broadcasting information. When the simulation results show that the broadcasting coverage area cannot completely cover the emergency area, the original broadcasting power of each broadcasting equipment to be activated is automatically adjusted to update the broadcasting coverage area, so as to ensure that the updated broadcasting coverage area can completely cover the emergency area, thereby improving the dissemination efficiency of broadcasting information.

[0019] One possible implementation also includes:

[0020] If a tangent broadcast coverage area exists, determine whether the tangent coverage point is the emergency center point of the emergency area;

[0021] If so, the broadcast power of the broadcast to be started corresponding to the tangent broadcast coverage area needs to be adjusted until the area corresponding to the coverage intersection area is not lower than a preset area threshold. The preset area threshold is determined by the anomaly level of the emergency area and the tunnel noise.

[0022] By adopting the above technical solution, and by comparing the tangent coverage point with the emergency center point of the emergency area, it is convenient to assess whether the broadcast prompts can be effectively transmitted to the core area of ​​the emergency area. Since the complex environment of the tunnel may cause the broadcast signal to attenuate or be blocked by obstacles during transmission, when the tangent coverage point is the emergency center point, it is necessary to form a sufficient coverage intersection area through at least two broadcast devices to be activated, so as to better adapt to the complex environment in the tunnel and thus ensure that the broadcast prompts can be fully transmitted in the emergency area.

[0023] In one possible implementation, tunnel indicator light control information is generated based on the emergency area, including:

[0024] At least one evacuation exit is determined based on the emergency area and the anomaly level corresponding to the emergency event.

[0025] Based on the relative position between the emergency area and each evacuation passage entrance, the route indicator light control information for each evacuation route corresponding to the evacuation passage entrance is determined. The route indicator light control information is used to control the tunnel indicator lights corresponding to each evacuation route.

[0026] Based on the severity level of the emergency event, the control information for the tunnel indicator lights corresponding to each evacuation tunnel entrance is determined. The control information for the tunnel indicator lights is used to control the tunnel indicator lights installed at each evacuation tunnel entrance.

[0027] The tunnel indicator light control information is generated based on the route indicator light control information and the passage entrance indicator light control information.

[0028] By adopting the above technical solution, at least one evacuation route entrance is determined by comprehensively considering the anomaly level of the emergency area and the emergency event. This facilitates the smooth evacuation of relevant personnel within the emergency area. In addition, the route indicator light control information and the entrance indicator light control information can accurately indicate the evacuation direction, enabling relevant personnel to quickly find and evacuate along the correct evacuation route. This helps to avoid getting lost or going the wrong way in an emergency, and also helps to avoid dangerous situations such as congestion and stampedes during the evacuation process, thereby improving the safety of the evacuation process.

[0029] One possible implementation also includes:

[0030] Acquire real-time tunnel images, and when the real-time tunnel images contain preset event features, identify the influence trajectory of the preset event features within a first preset time period;

[0031] Based on the influence trajectory, the predicted influence area corresponding to the preset event characteristics within a second preset time period is determined;

[0032] The broadcast prompt content is determined based on preset event characteristics, and the broadcast prompt content is broadcast in a targeted manner through the broadcasting equipment corresponding to the predicted impact area.

[0033] By adopting the above technical solution, the situation inside the tunnel can be monitored in real time, making it easier to detect abnormal situations in the tunnel in a timely manner. After determining the broadcast prompt content based on the preset event characteristics and the predicted impact area, the broadcast equipment corresponding to the predicted impact area will broadcast the information in a targeted manner to remind the relevant drivers in the predicted impact area. Targeted broadcasting not only improves the pertinence and effectiveness of the broadcast prompt information, but also helps to avoid unnecessary interference.

[0034] One possible implementation also includes:

[0035] The virtual panel displays the analog phone indicator lights corresponding to the emergency phone information, and the virtual panel contains analog phone indicator lights corresponding to all emergency phones in the tunnel to be managed.

[0036] The flashing information is determined based on the severity level of the emergency event corresponding to the emergency call, and the flashing information includes flashing duration and flashing frequency;

[0037] When the abnormality level is higher than the preset level, guidance information is determined based on the flashing position of the analog telephone indicator light in the virtual panel. The guidance information includes guidance shape and guidance direction.

[0038] The virtual panel is controlled based on the flashing information and the guidance information.

[0039] By adopting the above technical solution, the flashing status of the analog telephone indicator lights in the virtual panel provides a clear and intuitive understanding of the severity of the emergency within the emergency area. Furthermore, when the severity level is high, the visual feedback effect can be enhanced by adjusting the shape and direction of the indicator lights on other analog telephones in the virtual panel. This intuitive visual feedback immediately attracts the attention of relevant management personnel, enabling them to quickly locate the emergency telephone and take appropriate countermeasures, thereby improving the efficiency of emergency response.

[0040] Secondly, this application provides a management system, which adopts the following technical solution:

[0041] A management system comprising:

[0042] At least one processor;

[0043] Memory;

[0044] At least one application, wherein the at least one application is stored in memory and configured to be executed by at least one processor, the at least one application being configured to: execute the above-described integrated management method for tunnel emergency telephone and broadcast.

[0045] Thirdly, this application provides a computer-readable storage medium, which adopts the following technical solution:

[0046] A computer-readable storage medium includes: a computer program stored thereon that can be loaded by a processor and execute the aforementioned integrated management method for tunnel emergency telephone and broadcasting.

[0047] Fourthly, this application provides a computer program product, which adopts the following technical solution:

[0048] A computer program product includes a computer program that, when executed by a processor, implements the aforementioned integrated management method for tunnel emergency telephone and broadcast systems.

[0049] In summary, this application includes at least one of the following beneficial technical effects:

[0050] Analyzing emergency call information facilitates understanding the type, scale, and location of emergencies. It allows for determining whether broadcast assistance is needed based on the emergency type, rather than broadcasting all emergency calls. This enables relevant personnel to prioritize emergencies requiring broadcast assistance, thereby improving emergency response efficiency. Simultaneously broadcasting alerts to emergency areas and activating tunnel indicator lights further guides traffic flow within the tunnel, reducing chaos and secondary accidents. It also enhances the linkage between the emergency call mechanism, broadcast equipment, and tunnel indicator light mechanism. By adding linkage between the emergency call mechanism and other emergency mechanisms, information silos are reduced, improving coordination in emergency response and ultimately increasing the efficiency of responding to emergencies within the tunnel.

[0051] By comparing the tangent coverage point with the emergency center point of the emergency area, it is easier to assess whether the broadcast information can be effectively transmitted to the core area of ​​the emergency area. Since the complex environment of the tunnel may cause the broadcast signal to attenuate or be blocked by obstacles during transmission, when the tangent coverage point is the emergency center point, it is necessary to form a sufficient coverage intersection area through at least two broadcast devices to be activated, so as to better adapt to the complex environment in the tunnel and ensure that the broadcast information can be fully transmitted in the emergency area.

[0060] Specifically, this application provides an integrated management method for emergency telephone and broadcast systems in tunnels, executed by a management system. This management system can be a server or a terminal device. The server can be a standalone physical server, a server cluster or distributed system composed of multiple physical servers, or a cloud server providing cloud computing services. The terminal device can be a smartphone, tablet, laptop, desktop computer, etc., but is not limited to these. The terminal device and the server can be directly or indirectly connected via wired or wireless communication, and this application does not impose any limitations on this.

[0061] refer to Figure 1 , Figure 1 This is a flowchart illustrating an integrated management method for emergency telephone and broadcast systems in a tunnel, as described in this application. The method includes steps S110-S140, wherein:

[0062] Step S110: Obtain emergency call information, which includes emergency call information and emergency scene images.

[0063] Specifically, emergency telephones are located on both sides of the tunnel under management for use by personnel passing through the tunnel. When a driver encounters an emergency within the tunnel, they can press the button on the nearest emergency telephone terminal to send a call request to contact external rescue organizations. The emergency call information is generated after the emergency call is connected and mainly includes the driver's description of the emergency. The emergency telephones and the management system can communicate via a communication cable. In this embodiment, the communication cable is a shielded twisted-pair cable to effectively resist electromagnetic interference and improve data transmission quality. The call location can be located first based on the call request, and then emergency scene images can be obtained from the image acquisition device corresponding to the call location.

[0064] Step S120: Identify the emergency type corresponding to the emergency call information, and determine whether broadcast assistance is needed based on the emergency type.

[0065] Specifically, when the emergency type is a preset emergency type, it can be determined that broadcast assistance is needed. 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 a tunnel, especially one involving multiple vehicles or causing traffic disruption, emergency information needs to be immediately broadcast to relevant personnel in the tunnel via broadcasting equipment to remind them to pay attention to the road conditions ahead, take evasive action, and avoid secondary accidents. Different preset emergency types correspond to different emergency characteristics, and there is a feature mapping relationship between preset emergency types and emergency characteristics. Based on this feature mapping relationship, the preset emergency type corresponding to any emergency characteristic can be determined. For example, when the emergency call information contains characteristic 'a', or the emergency scene image contains characteristic 'b', it can be determined that the emergency characteristic corresponding to the emergency call information is a fire. The specific content of this feature mapping relationship is not specifically limited in this embodiment and can be determined by relevant personnel based on historical experimental data and then uploaded to the management system. The emergency type corresponding to the emergency call information can be determined based on a preset feature recognition algorithm. The specific preset feature recognition algorithm is not specifically limited in this embodiment.

[0066] Step S130: If yes, then determine the emergency area based on the emergency call information, and generate broadcast prompt information and tunnel indicator light control information based on the emergency call information and the emergency area.

[0067] Specifically, when the emergency type is the preset emergency type, it indicates that the relevant broadcasting equipment in the tunnel needs to be activated. The broadcasting equipment is generally installed in different areas inside the managed tunnel according to a preset layout to ensure that the broadcast sound can cover the entire managed tunnel. Meanwhile, due to the complex environment inside the tunnel, the broadcast signal may attenuate during transmission. Therefore, a power amplifier is generally installed in the equipment room near the entrance of the managed tunnel to enhance the broadcast signal strength, ensuring a high level of hearing during long-distance transmission. Except for the power amplifier, most other components can be flexibly replaced according to the actual application scenario. For example, the number and spacing of the broadcasting equipment 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 needed to better serve pedestrians. Considering the special circumstances of some areas, such as unstable geological conditions that may lead to unstable power supply, this embodiment of the application uses a dual power supply method of solar energy and the power grid to power the emergency telephones and broadcasting equipment. This method helps reduce energy waste and avoids the risk of communication interruptions due to power outages, thereby further enhancing the robustness of the management system.

[0068] An emergency zone is the area where an emergency occurs. The emergency location can be determined based on surrounding tunnel features or tunnel section markings provided by drivers in emergency calls. Then, the emergency zone is located from emergency scene images based on the emergency location. For example, when the emergency is a car accident, the emergency zone may include the accident site, the vehicle damage area, the area with injuries or fatalities, and the traffic congestion area. When the emergency is a vehicle fire, the emergency zone may include the burning vehicle and the traffic congestion caused by the fire. Different emergency events require different methods for determining the emergency zone. After identifying the emergency, the method for determining the emergency zone corresponding to different emergency events can be determined based on the mapping relationship between the emergency event and a preset determination strategy. The preset determination strategy mapping relationship includes the method for determining the emergency zone corresponding to each emergency event. The specific content is not specifically limited in this embodiment and can be determined by relevant personnel based on historical experimental data and then uploaded to the management system.

[0069] Once the emergency zone is identified, the indicator lights and broadcasting equipment in the managed tunnel need to be adjusted accordingly. Activating the indicator lights provides clear evacuation or avoidance routes for drivers and other affected individuals, reducing the risk of secondary accidents. Activating the broadcasting equipment allows for the rapid dissemination of emergency notices to drivers and other affected individuals, informing them of the specific location of the emergency, evacuation routes, and rescue measures, guiding them to evacuate in an orderly manner and preventing secondary injuries. The generated broadcast prompts are used to control the broadcasting equipment within the tunnel, and the generated tunnel indicator light control information is used to control the indicator lights within the tunnel for illumination.

[0070] Step S140: Based on tunnel indicator light control information and broadcast prompts, intervene in emergency events occurring in the emergency area.

[0071] Specifically, the broadcasting equipment, emergency telephones, and indicator lights are organically integrated and can share a single control console. This allows for unified control and management of these devices, eliminating the need to operate multiple systems separately, simplifying the operational process. Using a single communication cable for signal transmission reduces the number and complexity of communication cables, lowering construction and maintenance costs. Furthermore, this integrated approach ensures real-time information sharing among emergency equipment such as broadcasting devices, emergency telephones, and indicator lights, improving communication efficiency. In the event of an emergency, information can be quickly relayed via emergency telephones and promptly broadcast to relevant personnel, while indicator lights provide visual guidance, collectively forming a rapid response mechanism.

[0072] In this embodiment of the application, analyzing emergency call information facilitates understanding the type, scale, and location of the emergency. The type of emergency determines whether broadcast assistance is needed, rather than broadcasting all emergency call information. This allows relevant personnel to prioritize emergency events requiring broadcast assistance, thereby improving response efficiency. Simultaneously broadcasting alerts to emergency areas and activating tunnel indicator lights further guides traffic flow within the tunnel, reducing chaos and secondary accidents. It also enhances the linkage between the emergency call mechanism, broadcast equipment mechanism, and tunnel indicator light mechanism. By adding linkage between the emergency call mechanism and other emergency mechanisms, information silos are reduced, improving coordination in responding to emergencies and ultimately increasing the efficiency of responding to emergencies within the tunnel.

[0073] Furthermore, to improve the efficiency of broadcast notification information dissemination, this embodiment generates broadcast notification information based on emergency call information and emergency areas, which may specifically include:

[0074] Based on emergency call information, the anomaly level corresponding to the emergency event is determined. Based on the anomaly level and the emergency area, at least one broadcasting device to be activated is identified. The simulated broadcasting model corresponding to the at least one broadcasting device to be activated, as well as the personnel distribution and tunnel noise corresponding to the emergency area, are obtained. The simulated broadcasting model is driven based on the personnel distribution and tunnel noise to determine the broadcast coverage area. It is determined whether the broadcast coverage area can cover the emergency area. If not, the original broadcast power of each broadcasting device to be activated is adjusted until the updated broadcast coverage area can cover the emergency area. The updated broadcast coverage area is obtained based on the simulated broadcasting model driven by the adjusted broadcast power. A broadcast prompt message is generated based on each broadcasting device to be activated and the adjusted broadcast power of each broadcasting device to be activated.

[0075] Specifically, when it is necessary to generate a broadcast prompt message, the emergency type representing the emergency event is a preset emergency type, which may be one of traffic accidents, fires, equipment failures, and natural disasters. Different preset emergency types correspond to different first abnormality scores. The first abnormality score of the emergency event corresponding to the preset emergency type can be determined based on the preset first score mapping relationship. The preset first score mapping relationship includes the first abnormality scores corresponding to different preset emergency types. Then, based on the influence area of ​​the emergency area and the preset second score mapping relationship, the second abnormality score of the emergency area corresponding to the emergency event is determined. The preset second score mapping relationship is the correspondence between the influence area and the second abnormality score. The sum of the first abnormality score and the second abnormality score corresponding to the emergency event is calculated to determine the total abnormality score. Finally, the abnormality level corresponding to the total abnormality score is determined based on the preset level mapping relationship. The specific content of the preset first score mapping relationship, the preset second score mapping relationship, and the preset level mapping relationship is not specifically limited in this application embodiment. They can be determined by relevant personnel based on historical experimental data and then uploaded to the management system.

[0076] The higher the anomaly level, the more broadcasting devices need to be activated. There is a correlation between the anomaly level and the number of devices. Based on this correlation, the number of broadcasting devices to be activated for any given anomaly level can be determined. After determining the number of devices to be activated, the specific devices can be identified sequentially, centered on the emergency area. However, after identifying the specific devices to be activated, the broadcast is not immediately started. Instead, the broadcast coverage of these devices needs to be simulated to predict or assess the propagation of the broadcast signal in the actual tunnel environment, including the signal coverage, intensity, and potential blind spots.

[0077] The broadcast coverage areas corresponding to two adjacent broadcast devices to be activated can be simulated in pairs. Finally, by comparing the overall broadcast coverage area of ​​all broadcast devices to be activated with the emergency area, it can be determined whether the original broadcast power of the broadcast devices to be activated needs to be adjusted. For any pair of adjacent broadcast devices to be activated, a simulated broadcast model for each device can be obtained. Based on the personnel distribution in the corresponding emergency area and tunnel noise, the simulated broadcast models of the adjacent broadcast devices to be activated can be driven, thus simulating the actual broadcast effect in the tunnel after the two adjacent broadcast devices are activated. The emergency area corresponding to the two adjacent broadcast devices to be activated is the emergency area located between the two adjacent broadcast devices. Since the personnel distribution in the tunnel may affect the broadcast effect, and since vehicle traffic and mechanical operation in the tunnel will generate noise, tunnel noise may interfere with the transmission and reception of broadcast signals, thus also affecting the broadcast effect, referencing personnel distribution and tunnel noise is crucial in simulating the actual broadcast effect. Personnel distribution can be located by detecting emergency scene images. Specifically, personnel detection can be performed on emergency scene images using a preset personnel feature recognition algorithm, including the number and location of personnel. The specific preset personnel feature recognition algorithm is not specifically limited in this embodiment. Noise can be collected by noise monitoring devices installed in the tunnel to be managed, and then uploaded to the management system. These devices can be noise meters, sound level meters, etc. If the simulation results show that the broadcast coverage area of ​​two adjacent broadcast devices can cover the corresponding emergency area, then there is no need to adjust the broadcast power of the two adjacent broadcast devices; that is, the two adjacent broadcast devices can be controlled to broadcast at their original broadcast power. If the simulation results show that the broadcast coverage area cannot cover the corresponding emergency area, then the broadcast power of the two adjacent broadcast devices needs to be adjusted. That is, the broadcast power needs to be increased based on the original broadcast power. The specific increase in power is not specifically limited in this embodiment, as long as the broadcast coverage area generated by the two adjacent broadcast devices broadcasting at the adjusted broadcast power can cover the corresponding emergency area.

[0078] The above method can be used to evaluate or adjust the broadcast power of each broadcasting device to be started. Since each broadcasting device to be started is located in a different position, the distribution of people and tunnel noise are different when predicting or evaluating the broadcast coverage area generated by broadcasting devices to be started in different locations. Therefore, the power increase value corresponding to the adjustment of the original broadcast power of different broadcasting devices to be started is also different. Finally, based on each broadcasting device to be started and the adjusted broadcast power of each broadcasting device to be started, a broadcast prompt message is generated, thereby improving the dissemination efficiency of the broadcast prompt message.

[0079] Furthermore, to ensure that broadcast notification information can be fully disseminated in emergency areas, the method provided in this application embodiment further includes steps S210 and S220, such as... Figure 2 As shown, where:

[0080] 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.

[0081] Specifically, a tangent broadcast coverage area indicates that the partial broadcast coverage areas of two adjacent broadcast devices to be activated are tangent. If it is detected that the partial broadcast coverage areas of two adjacent broadcast devices to be activated are tangent, it is necessary to determine whether the tangent coverage point of the partial broadcast coverage areas of the two adjacent broadcast devices to be activated 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 of the two adjacent broadcast devices to be activated can cover the corresponding partial emergency area, the broadcast power of the two adjacent broadcast devices to be activated still needs to be adjusted. Due to the complex environment of the tunnel, the broadcast signal may attenuate or be blocked by obstacles during transmission. Therefore, in order to ensure that the relevant drivers or other affected personnel located in the center of the emergency area can accurately receive the broadcast content, adjustments are needed.

[0082] Step S220: If so, the broadcast power of the broadcast to be started corresponding to the tangent broadcast coverage area needs to be adjusted until the area corresponding to the coverage intersection area is not lower than the preset area threshold. The preset area threshold is determined by the abnormal level of the emergency area and the tunnel noise.

[0083] Specifically, when the broadcast coverage areas of two adjacent broadcast devices to be activated are tangent, the broadcast power of the two adjacent broadcast devices to be activated needs to be further adjusted until the broadcast coverage areas of the two adjacent broadcast devices to be activated intersect, such as... Figure 3 As shown, after adjusting the broadcast power of broadcast device 1 and broadcast device 2 to be started, the broadcast coverage areas of broadcast device 1 and broadcast device 2 to be started changed from the original tangent state to the intersection state.

[0084] However, it is not sufficient for two adjacent broadcast devices to have overlapping broadcast coverage areas. Instead, the minimum area of ​​the overlapping coverage area needs to be determined based on the anomaly level of the emergency area and the tunnel noise. Different combinations of anomaly levels and tunnel noise correspond to different preset area thresholds, which can be determined through a preset threshold mapping relationship. The preset threshold mapping relationship is the correspondence between different combinations of anomaly levels and tunnel noise and preset area thresholds. The specific content of this preset threshold mapping relationship is not specifically limited in this embodiment.

[0085] In this embodiment of the application, by comparing the tangent coverage point with the emergency center point of the emergency area, it is convenient to assess whether the broadcast prompt information can be effectively transmitted to the core area of ​​the emergency area. Since the complex environment of the tunnel may cause the broadcast signal to attenuate or be blocked by obstacles during transmission, when the tangent coverage point is the emergency center point, it is necessary to form a sufficient coverage intersection area through at least two broadcast devices to be activated in order to better adapt to the complex environment in the tunnel.

[0086] Furthermore, to improve safety during evacuation and prevent disorientation or wrong turns in emergencies, tunnel indicator light control information is generated based on the emergency area, specifically including:

[0087] At least one evacuation exit is determined based on the anomaly level corresponding to the emergency area and the emergency event. Based on the relative position between the emergency area and each evacuation exit, route indicator light control information for each evacuation route corresponding to the evacuation exit is determined. The route indicator light control information is used to control the tunnel indicator lights corresponding to each evacuation route. Based on the anomaly level of the emergency event, access point indicator light control information is determined for each evacuation exit. The access point indicator light control information is used to control the tunnel indicator lights set at each evacuation exit. Tunnel indicator light control information is generated based on the route indicator light control information and the access point indicator light control information.

[0088] Specifically, the number of evacuation exits corresponding to the abnormality level can be determined first based on the preset channel mapping relationship. Then, the corresponding number of evacuation exits can be selected from the emergency area or the adjacent area of ​​the emergency area. The preset channel mapping relationship is the correspondence between the abnormality level and the number of evacuation exits. The specific content of the preset channel mapping relationship is not specifically limited in this application embodiment. It can be determined by relevant personnel based on historical experimental data and then uploaded to the management system.

[0089] Since evacuation exits may be located on either side of an emergency zone or on either side of an adjacent area, it is necessary to determine the evacuation route corresponding to each evacuation exit based on the relative position between the emergency zone and each evacuation exit. Then, based on each evacuation route, the lighting color and frequency of each tunnel indicator light along that route are determined. The route indicator light control information in this application does not directly turn on all tunnel indicator lights along the evacuation route; instead, it forms evacuation direction arrows or signs based on the direction of the evacuation exit. Besides illuminating the tunnel indicator lights, it also clarifies the evacuation direction for evacuees. Specific lighting colors and evacuation direction signs are not specifically limited in this embodiment. Based on the above method, the route indicator light control information corresponding to each evacuation route can be determined.

[0090] In addition to the tunnel indicator lights corresponding to the evacuation routes needing to be illuminated, tunnel indicator lights are also installed above each evacuation passage entrance. The flashing frequency of these tunnel indicator lights needs to be determined based on the severity of the emergency zone; the higher the severity, the higher the flashing frequency. Finally, based on the route indicator light control information and the passage entrance indicator light control information, the tunnel indicator lights along the evacuation routes and those at the evacuation passage entrances are controlled separately to ensure that relevant personnel can quickly find and evacuate along the correct evacuation route.

[0091] Furthermore, the method provided in this application embodiment also includes:

[0092] Acquire real-time tunnel images. When the real-time tunnel images contain 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 broadcast the broadcast prompt content in a targeted manner through the broadcasting device corresponding to the predicted influence area.

[0093] Specifically, the method provided in this application not only activates broadcasting equipment, indicator lights, and other emergency devices only after receiving an emergency call, but also promptly detects potential abnormal events within the managed tunnel by monitoring real-time tunnel images. These real-time tunnel images are captured by image acquisition devices installed within the managed tunnel and uploaded to the management system in real time. A preset feature recognition algorithm can be used to detect whether the real-time tunnel image contains preset event features, such as vehicle lane departure or unstable speed. Based on extracted lane and vehicle features, it can be determined whether a vehicle has deviated from its lane. A specific deviation threshold can be set; for example, if the distance between the vehicle and the lane line exceeds the deviation threshold, the vehicle is considered to have deviated from its lane. A target detection algorithm can be used to detect the vehicle's position in the real-time tunnel image and record the vehicle's position information at different time points to determine if the vehicle's speed is unstable.

[0094] When a preset event feature is detected in a real-time tunnel image, the vehicle containing the preset event feature is identified as a potential hazard vehicle. The impact trajectory of the potential hazard vehicle within a first preset time period is recorded based on the preset event feature. The first preset time period is a period of time after the potential hazard vehicle is identified. The duration of the first preset time period can be 1 minute or 2 minutes. The specific duration is not specifically limited in this application embodiment.

[0095] Based on the impact trajectory and the duration of the second preset time period, a prediction algorithm is used to predict the area that the potentially hazardous vehicle may affect within the second preset time period. The prediction algorithm can be linear prediction, machine learning models, etc., and the specific prediction algorithm is not specifically limited in this embodiment. The predicted impact area can be one or more polygonal or circular areas, covering the driving path of the potentially hazardous vehicle within the second preset time period. Different preset event characteristics correspond to different broadcast prompts. The broadcast equipment corresponding to the predicted impact area broadcasts targeted messages to relevant drivers within the predicted impact area, providing targeted reminders. If the driver of the potentially hazardous vehicle cannot adjust their driving status in time, targeted reminders can alert relevant drivers within the predicted impact area to take evasive action in advance to avoid a collision with the potentially hazardous vehicle. Furthermore, targeted broadcasting not only improves the relevance and effectiveness of the broadcast prompts but also helps avoid unnecessary interference.

[0096] To facilitate relevant management personnel in quickly locating emergency calls and taking timely countermeasures, the method provided in this application embodiment further includes:

[0097] The virtual panel illuminates the analog telephone indicator lights corresponding to emergency telephone information. The virtual panel contains analog telephone indicator lights corresponding to all emergency telephones in the tunnel to be managed. Flashing information is determined based on the anomaly level of the emergency event corresponding to the emergency telephone. The flashing information includes flashing duration and flashing frequency. When the anomaly level is higher than the preset level, guidance information is determined based on the flashing position of the analog telephone indicator lights in the virtual panel. The guidance information includes guidance shape and guidance direction. The virtual panel is controlled based on the flashing information and guidance information.

[0098] Specifically, the virtual panel can be set up in the control console. The virtual panel contains analog telephone indicator lights corresponding to each emergency telephone within the tunnel. When an emergency occurs in the tunnel, the driver will press the button on the nearest emergency telephone to contact external rescue services. The control console will immediately identify the location of the call and transfer it to the designated personnel. Simultaneously, the corresponding indicator light on the virtual panel will illuminate. Different anomaly levels correspond to different flashing information; higher anomaly levels correspond to longer flashing durations and faster flashing frequencies. The flashing information for different anomaly levels can be determined based on a preset flashing mapping relationship, which establishes a correspondence between anomaly levels and flashing information.

[0099] Since the virtual panel contains analog telephone indicator lights corresponding to all emergency telephones within the managed tunnel, more than one indicator light may be lit at the same time. In this case, the lighting pattern of the virtual panel can be adjusted according to the severity level of the emergency event corresponding to each emergency telephone. When the severity level is high, the lighting patterns of other analog telephone indicator lights in the virtual panel can be adjusted to increase the attention of relevant management personnel to the indicator lights with higher severity levels. When the severity level of an analog telephone indicator light is higher than a preset level, the indicative area and guidance information are determined based on the flashing position of the indicator light in the virtual panel. Then, the guidance shape is displayed within the indicative area of ​​the virtual panel according to the guidance direction. The guidance shape can be an arrow or any other symbol that can represent direction, indicating the direction pointing towards the analog telephone indicator light. When the severity level is high, the visual feedback effect is enhanced by adjusting the guidance shape and direction of other analog telephone indicator lights in the virtual panel, thereby facilitating relevant management personnel to quickly locate emergency telephones and take appropriate countermeasures in a timely manner.
