[0040] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0041] For ease of understanding, the terms involved in the embodiments of the present application are explained below:

[0042] (1) Sectional passenger flow: The number of passengers passing through a section of a rail transit line in the same direction within a unit of time, that is, the passenger flow passing through the section where the section is located. It is divided into upward section passenger flow and downward section passenger flow.

[0043] (2) Personnel costs: In rail transit systems, the number of security personnel and training costs may be high, which will increase the cost of handling rail transit security incidents.

[0044] (3) Equipment cost: The cost of purchasing, installing and maintaining security equipment is also high, especially for advanced monitoring systems and alarm equipment, which are more expensive.

[0045] (3) Emergency plan costs: Formulating a comprehensive emergency plan requires a lot of manpower and material resources, which will also increase the cost of handling rail transit security incidents. Security equipment requires regular repair and maintenance, which will also increase the cost of handling rail transit security incidents.

[0046] (4) Loss cost: If security incidents are not handled properly, it may lead to interruption of rail transit system operations and property loss of passengers, which will also bring high costs.

[0047] With the development of intelligence, the handling of security incidents in the field of rail transit is becoming more and more intelligent. Quick and accurate handling of security incidents can effectively reduce personal danger and property losses.

[0048] In the related technology, a unified processing flow is applied to handle all security events. On the one hand, this may result in a high misjudgment rate, which in turn leads to a low timeliness and accuracy of processing; on the other hand, it may also cause improper processing, resulting in personal danger and property loss.

[0049] To this end, the embodiment of the present application provides a method for handling security events based on rail transit. In this method, security events are divided into other categories according to the type of security events. One category is called prejudgment events, which are events that need to be handled as soon as possible, such as those that need to be handled within the first time period; the other category is called scene events, which are less urgent than prejudgment events, such as those that need to be handled within the second time period, and the second time period is greater than the first time period. For the first category and prejudgment events, the pre-handling operation is performed first, and then the scene handling operation is performed, so that the security events can be handled in time, reducing personnel dangers and property losses; for the second category of scene handling events, the scene handling operation is directly performed, which can effectively assist the staff in handling and improve the handling efficiency and accuracy. The pre-handling operation here includes equipment emergency control operation (for example, a person falls in an elevator) or verification of the type of security event operation (for example, whether it is a real large passenger flow situation); the scene handling operation includes equipment control operation and information distribution operation, which realizes different operations according to different types of security events, which is more targeted.

[0050] To further illustrate the technical solution provided by the embodiment of the present application, this is described in detail below in conjunction with the accompanying drawings and specific implementation methods. Although the embodiment of the present application provides the method operation steps shown in the following embodiments or drawings, more or fewer operation steps may be included in the method based on routine or no creative labor. In the steps where there is no necessary causal relationship logically, the execution order of these steps is not limited to the execution order provided in the embodiment of the present application.

[0051] Figure 1aA flowchart of a method for handling security incidents based on rail transit provided in an embodiment of the present application is provided to illustrate the technical solution provided in an embodiment of the present application.

[0052] S101: Obtain video data to be processed.

[0053] S102: Identify the video data to be processed, and determine the type of security event corresponding to the video data to be processed.

[0054] S103: If the security event is a predicted event, a corresponding pre-processing operation is performed on the security event, and a corresponding scene processing operation is performed after the pre-processing operation is completed.

[0055] Among them, the predicted event is a security event that needs to be handled within the first period of time; among them, the pre-handling operation includes equipment emergency control operation or security event type verification operation; the scene handling operation includes equipment control operation and information sending operation.

[0056] S104: If the security event is a scene handling event, a corresponding scene handling operation is performed on the security event.

[0057] Among them, the scene handling event is a security event that needs to be handled within a second time period; the second time period is greater than the first time period.

[0058] In an embodiment of the present application, video data to be processed is obtained, the video data to be processed is identified, and the type of security event corresponding to the video data to be processed is determined. Based on different types of security events, a dynamic security event processing mechanism is formed. If the security event is a predicted event, the corresponding pre-processing operation is performed on the security event, and the corresponding scene processing operation is performed after the pre-processing operation is completed; if the security event is a scene processing event, the corresponding scene processing operation is performed on the security event. The pre-processing event here is a security event that needs to be processed within a first time length, and the scene processing event is a security event that needs to be processed within a second time length; the second time length is greater than the first time length. The pre-processing operation includes an equipment emergency control operation or a security event type verification operation; the scene processing operation includes an equipment control operation and an information distribution operation. Such a design improves the timeliness and accuracy of security event processing, thereby reducing personnel dangers and property losses.

[0059] The method for processing security events based on rail transit in the embodiment of the present application can be executed by a data processing device. The event processing device may include the following components, each of which is used to perform different functions. First, with the components as the dimension, reference Figure 1b , the entire process of this application is explained.

[0060] Security event trigger component: The video analysis algorithm component serves as the trigger source for security event handling. It provides security event identification through analysis of real-time video streams and pushes the identified raw first-hand information to the auxiliary judgment component module.

[0061] Security event analysis component: The system is mainly composed of a building information modeling (BIM) module, a Bluetooth wireless positioning module, and an event analysis system. The BIM model provides model data for the entire station, such as the location information of equipment in the station. The Bluetooth wireless positioning system provides precise location coordinates through the staff wearing a special positioning bracelet. The above two modules provide the necessary data support for the event analysis system. The event analysis system generates security event alarms through equipment and personnel data and pushes them to the scene handling system.

[0062] Security scene handling system components: The security scene handling system is the core module of the entire system. It is mainly composed of two functions, one is to provide users with the pre-handling function of security scenes, and the other is the scene process automatic handling execution function. After the scene occurs, the action is quickly and automatically executed, triggering the linkage of equipment and information monitoring, and providing professional action guidance for the staff to complete the handling of scene events.

[0063] In summary, data processing equipment realizes the full life cycle management of security scenes from triggering to ending. Security event identification meets the triggering conditions, and automatically forms a disposal flow according to the event type. After the event analysis is passed, the scene is triggered, a scene instance is created, and the visual operation process of the scene begins. Conventional scenes directly enter the scene disposal, and the corresponding actions are performed according to the direction of the process to complete the scene disposal; some types of scenes first perform manual pre-judgment disposal of the scene, and can quickly decide whether to enter the disposal or complete the emergency equipment control, and then enter the scene disposal to execute the action. The scene ends after the video action, monitoring action, equipment control action, etc. are automatically executed.

[0064] Next, the embodiments of the present application are described in detail:

[0065] In S101, the monitoring device generally refers to a camera, which captures the video image of its own range in real time. In the embodiment of the present application, after the video is abnormal, the camera that reports the abnormal video data can be called an alarm device. In this step, the reported abnormal video data is called the video data to be processed, and the camera that reports the video data to be processed is called an alarm device.

[0066] Regarding S102, since the video data to be processed includes abnormal videos, the video data to be processed may be analyzed to determine the type of security event corresponding to the video data to be processed.

[0067] In a specific example, the types of security events may be passenger injury, large passenger flow, object monitoring, personnel monitoring, dangerous action, personnel counting, intrusion, and the like.

[0068] The following describes the process of how to determine the intrusion class and the personnel counting class.

[0069] The first type: Invasion type.

[0070] Among them, intrusion events refer to the entry of people into areas that are not allowed to enter.

[0071] Figure 2 A schematic diagram of a process for identifying an intrusion-type security event provided in an embodiment of the present application, which may refer to the following steps for details:

[0072] S201: Identify video data to be processed and determine an alarm device to report the video data to be processed.

[0073] The video data to be processed may carry a field for indicating the alarm device identification, so the alarm device that reports the video data of the device to be processed is determined by identifying the video data to be processed. Exemplarily, the identification of the alarm device may be represented by a unique identification code, which may indicate the number and location of the alarm device, such as camera No. 0002 in the waiting hall.

[0074] S202: Determine the first coordinates of the alarm device according to the identifier of the alarm device.

[0075] Among them, the location information of the alarm device can be determined through the identification of the alarm device, and the location information can be represented by a first coordinate. The first coordinate here can be a corner of the entire station hall as the origin of the positioning coordinate system.

[0076] S203: According to a preset conversion relationship between the positioning coordinate system and the model coordinate system, the first coordinate is converted into a first target coordinate in the model coordinate system.

[0077] The BIM model is a way to abstract physical equipment or space into a model to model the relevant areas of rail transit. In the BIM model, each entity corresponds to a model, and the location of the entity corresponds to its location in the BIM model. The entity here can be equipment or people.

[0078] In the embodiment of the present application, the first coordinate can be converted into a first target coordinate in the model coordinate system according to a preset conversion relationship between the positioning coordinate system and the model coordinate system. In this example, one dimension of the coordinate in the model coordinate system can be used to represent a floor.

[0079] S204: Determine a first coordinate range of the visible area of ​​the alarm device by applying the visible area information of the alarm device and the first target coordinates.

[0080] Among them, each camera has a monitorable range, which can be represented by visible area information. Therefore, the visible area information and the first target coordinates of the alarm device (alarm camera) can be applied to determine the first coordinate range of the visible area of ​​the alarm device in the BIM coordinate system.

[0081] S205: For each target object, obtain the second coordinate of the target object, and convert the second coordinate into a second target coordinate in the model coordinate system according to the conversion relationship.

[0082] The target object may be a staff member, such as a cleaning staff, a security guard, etc. Each target object may be equipped with a positioning device such as a positioning bracelet. Therefore, for each target object, its second coordinate in the positioning coordinate system can be obtained in real time, and then the second coordinate is converted into the second target coordinate in the model coordinate system according to the conversion relationship.

[0083] S206: If there is a second target coordinate within the first coordinate range, determine that the security event corresponding to the video data to be processed is an intrusion security event.

[0084] Therefore, if there is a second target coordinate located within the first coordinate range, it can be determined that the security event corresponding to the video data to be processed is an intrusion-type security event.

[0085] By applying the method in the embodiment of the present application, it is possible to distinguish whether the person involved in an intrusion-type security incident is a staff member. Compared with the prior art that can only identify human intrusion, the possibility of false alarms is reduced.

[0086] The second type is personnel statistics.

[0087] Figure 3 A schematic diagram of a process for identifying a security event of personnel statistics provided in an embodiment of the present application, which may refer to the following steps for details:

[0088] S301: Identify video data to be processed and determine an alarm device to report the video data to be processed.

[0089] The implementation method of this step can refer to step S201 and will not be repeated here.

[0090] S302: Determine the first coordinates of the alarm device according to the identifier of the alarm device.

[0091] The implementation method of this step may refer to step S202 and will not be described in detail here.

[0092] S303: Determine at least one monitoring device included in the target area according to the location information of the target area, the location information of each monitoring device in the BIM model, and the visible area information of each monitoring device.

[0093] The target area is an area pre-set according to the demand, for example, the set area is the station entrance area, therefore, the location information of the station entrance area in the BIM model can be obtained, and according to the location information of each monitoring device in the BIM model and the visible area information of each monitoring device, it can be determined which monitoring devices are located in the target area and which monitoring devices are not located in the target area. In this way, at least one monitoring device included in the target area can be determined.

[0094] S304: Determine that the sum of the number of persons monitored by at least one monitoring device is a first number.

[0095] In this example, the sum of the number of people monitored by the at least one monitoring device is obtained as the first number N1.

[0096] S305: Acquire location information of each target object, and determine a second number of target objects included in the target area according to the location information.

[0097] The location information of each target object is reported in real time. The data processing device retrieves the real-time coordinate data of the staff of the wireless positioning system, so that the second number of target objects included in the target can be determined to be N2.

[0098] In this process, due to the frequent activities of staff, they may go in and out of the statistical area repeatedly, causing data drift. Therefore, stable data features can be selected, and the data changes at the second level are considered invalid data, and the data can be denoised to reduce the impact of data drift.

[0099] S306: Determine a target quantity according to the first quantity and the second quantity.

[0100] The target number is the difference between the first number N1 and the second number N2, which is expressed as N=N1-N2.

[0101] S307: Determine, based on the target quantity, that the security event is a personnel quantity statistics type.

[0102] In the embodiment of the present application, the security event may be determined to be a personnel data statistics type.

[0103] Since the types of security events are different, different security events require different responses. Therefore, after obtaining the type of security event corresponding to the video data to be processed, it is possible to first determine whether it is a predicted event or a scene handling event, and then perform different operations. Among them, a predicted event is a security event that needs to be handled within a first time period, and a scene handling event is a security event that needs to be handled within a second time period, and the second time period is greater than the first time period. For example, passenger injury events are predicted events that need to be handled as soon as possible to avoid personal injury; object monitoring events are scene handling events, and as long as they are handled within the second time period, property losses can be reduced.

[0104] For the predicted event, refer to step S103 and perform the following operations:

[0105] If the security event is a predicted event, the corresponding pre-processing operation is performed on the security event, and the corresponding scene processing operation is performed after the pre-processing operation is completed. The automatic switching from pre-processing operation to scene processing operation is realized.

[0106] Among them, the pre-processing operation includes equipment emergency control operation or security event verification operation. The equipment emergency control operation here can be to stop the escalator when someone falls; the security event verification operation here can be to verify whether it is really a large passenger flow event after monitoring the gathering of people through cameras.

[0107] Exemplarily, if the predicted event is an additional handling event, the pre-handling operation includes an equipment emergency control operation; if the predicted event is an additional verification event, the pre-handling operation includes a security event type verification operation.

[0108] In the prediction event, the following two situations are taken as examples:

[0109] Case 1: The additional handling event is a security incident involving passenger injury.

[0110] In this case, you can refer to the pre-processing operations for security events. Figure 4a , Figure 4a At least the following steps are included:

[0111] S401: Determine the subtype of the passenger injury event to which the security event belongs.

[0112] Among them, when the additional handling event is a passenger injury security event, it corresponds to different subtypes. For example, one subtype is an escalator passenger injury event, and another subtype is a passenger injury event caused by a stuck freight elevator door, etc. This is just an example and does not constitute a specific limitation.

[0113] For escalator equipment control, when there are many people on the escalator, the escalator slow stop will fail and it will take a long time to stop; when there are few people on the escalator, the escalator emergency stop may cause people to lose balance and cause injuries. Therefore, the embodiment of the present application proposes a method for adaptively controlling the escalator according to the on-site situation.

[0114] S402: Display at least one operation control corresponding to the subtype.

[0115] One purpose of considering the predicted events separately is to reduce personal injury. Therefore, after determining the subtype of the passenger injury event to which the security event belongs, at least one operation control corresponding to the subtype is displayed in order to quickly provide a solution. For example, if the subtype is an escalator passenger injury event, then at least one operation control can realize functions such as escalator emergency stop and escalator slow stop.

[0116] In a specific example, Figure 4b A page diagram for handling customer injury-related security incidents provided in an embodiment of the present application. Figure 4b The "Escalator Stop" control is shown in FIG.

[0117] S403: Respond to the user's operation on the target operation control to perform a device emergency control operation on the device represented by the target operation control.

[0118] The target operation control is one operation control among the at least one operation control, and the target operation control is determined according to the number of persons involved in the security event.

[0119] For example, if the number of people included in the security event is greater than a threshold number of people (e.g., 10 people), the target operation control can be determined to be an emergency stop control; if the number of people included in the security event is less than or equal to the threshold number of people, the target operation control can be determined to be a slow stop control.

[0120] In this example, for the passenger injury security event with the subtype of escalator, you can refer to Figure 5 , determine the number of people included in the security incident by:

[0121] S501: Determine the escalator associated with the security event.

[0122] Among them, the escalator associated with the security event can be determined through the location information of the alarm device.

[0123] S502: If the number of people on the escalator identified by the monitoring device within the set range of the escalator is less than or equal to the first value, it is determined that the number of people included in the security event is the number of people on the escalator identified by the monitoring device.

[0124] Among them, when there are fewer people on the escalator, the camera recognizes the number of people with high accuracy. If the number of people recognized by the camera is within the first value (for example, 5 people), the system uses the escalator slow stop control. In other words, if the number of people on the escalator identified by the set range of the escalator (for example, within 5 meters) is less than or equal to 5, it means that the number of people is small and the recognition result is accurate. Therefore, it can be determined that the number of people included in the security event is the number of people on the escalator identified by the monitoring equipment.

[0125] S503: If the number of people on the escalator identified by the monitoring device within the set range of the escalator is greater than a first value, the number of people included in the security event is determined based on the identified number of people on the escalator and the load-bearing capacity of the escalator.

[0126] For example, when there are many people on the escalator, the camera's accuracy in identifying the number of people is low, and the escalator's load-bearing capacity is combined to make a judgment. If the number of people on the escalator identified by the monitoring equipment within the set range of the escalator is 10, the recognition result may be inaccurate due to crowding. Therefore, the number of people included in the security event can be determined based on the number of people identified on the escalator and the escalator's load-bearing capacity.

[0127] In a specific example, the process of determining the number of people involved in the security incident in this step is described:

[0128] Number of people = number of identified people * 0.4 + load-bearing capacity of escalator / 60 * 0.6; the unit of load-bearing capacity of escalator is KG.

[0129] The embodiment of the present application performs pre-processing for passenger injuries, thereby achieving rapid processing of security incidents and quickly implementing personnel rescue, thereby avoiding missing the opportunity for processing and causing secondary injuries to passengers.

[0130] Case 2: The additional verification event is a security incident involving large passenger flow.

[0131] In this case, you can refer to the pre-processing operations for security events. Figure 6a , Figure 6a At least the following steps are included:

[0132] S601: Determine an event area represented by a security event.

[0133] Each security event may correspond to an event area, such as an escalator, a station stop or a waiting room, etc. In the embodiment of the present application, the event area represented by the security event corresponding to the video data to be processed is determined.

[0134] S602: Determine whether a large passenger flow security event is valid based on the real-time passenger flow in the event area, the cumulative passenger flow in the event area within a preset time range, the cross-sectional passenger flow, and the model passenger flow density determined by the BIM model.

[0135] Among them, the video data of each camera that can capture the event area can be obtained, and the real-time passenger flow of each camera in the time area can be analyzed, and then the cumulative passenger flow and cross-sectional passenger flow of the event area within the preset time range can be calculated based on the real-time passenger flow. The BIM model can be used to determine the model passenger flow density, that is, to calculate the passenger flow density in the event area from the perspective of the model. These data are used to further verify whether the confirmed large passenger flow security events are effective.

[0136] S603: If it is determined that the large passenger flow security event is valid, then it is determined that the large passenger flow security event has been additionally verified.

[0137] When it is determined that the large passenger flow event is valid, the additional verification is determined to be passed. Compared with judging the large passenger flow security event only by the real-time passenger flow of the camera, this design reduces the occurrence of misjudgment and improves the recognition accuracy.

[0138] Figure 6b A schematic diagram of a large passenger flow pre-processing page provided in an embodiment of the present application.

[0139] The embodiment of the present application performs preprocessing based on time, space and personnel, thereby improving the reliability and handling efficiency of the system. Assuming that the verification result is a large passenger flow security event, compared with the prior art that can only identify the total number of people in the evacuation area and cannot exclude staff and security personnel, the reliability of personnel statistics is improved, thereby improving the scene handling effect.

[0140] For the scene handling event, refer to step S104 and perform the following operations:

[0141] If the security event is a scene handling event, the corresponding scene handling operation is performed on the security event. In the scene handling operation, different scene instances can be created according to the types of security events, which may involve control actions, broadcast and distribution actions, notification actions, detection actions, device control actions, and front-end information display actions.

[0142] During the scene execution, the system provides the ability to switch the viewing angle at any time by clicking on the camera on the BIM to view the real-time video. You can also click on the staff model on the BIM to directly locate the position. Based on the staff position coordinates provided by the wireless Bluetooth system and the camera coordinates in the BIM model, after eliminating the influence of floor differences, the system uses the developed surrounding camera recognition algorithm to obtain the nearest 4 cameras based on the viewing angle and coordinates for real-time video playback. During the scene execution, users can view the alarm screenshots and historical videos when the event occurs in the information monitoring area. The data comes from the video analysis system. This is convenient for tracing back to the situation at the scene.

[0143] Exemplarily, the scene handling operation includes a device control operation and an information delivery operation. The following is an explanation using a specific example:

[0144] In the scene processing operation, it is mainly divided into the following operations:

[0145] Operation A: The device control operation is to first control the device to perform a first control action.

[0146] The first control device is a pre-set device; or, the first control device is a device determined according to the location information of the alarm device and a pre-set device type; the first control action is an action matching the first control device;

[0147] In this operation, one mode A1 is to pre-set a device, such as escalator No. XXX, and another mode A2 is not to pre-set a specific device, but to set the device type. For example, the pre-set device type is escalator, and the first control device is an escalator within a certain range near the alarm device. In these two modes, the first control action matches the first control device. For example, the action matched by the escalator is usually to stop running.

[0148] Operation B: Information sending operation includes notification message sending operation and video stream push operation.

[0149] B1: the notification delivery operation is a first delivery object and a first delivery action; the first delivery object is a preset object; or the first delivery object is an object determined according to the location information of the alarm device and a preset object type; the first delivery action includes an action matching the first delivery object;

[0150] In this operation, one method B11 is to pre-set the delivery object, such as the cleaner No. YYY and the security guard No. ZZZ; another method B12 is not to pre-set the delivery object, but to pre-set the object type, such as the security guard and the cleaner, then the first delivery object can be the security guard and the cleaner within a certain range near the alarm device. In these two methods, the first delivery action is the action that matches the first delivery object, such as the security guard stopping a freight elevator.

[0151] B2: The first pushed content pushed by the video stream push operation is a preset video stream of a monitoring device; or the first pushed content is a video stream of a monitoring device associated with the alarm device determined according to the location information of the alarm device.

[0152] Among them, in this case, one method B21 is to pre-set the WWW camera and push its video stream and reverse direction; another method B22 is to determine the cameras within a certain range nearby as associated cameras based on the location information of the alarm device, and push the video stream of the associated camera.

[0153] In the embodiment of the present application, messages or video streams can be automatically sent to relevant personnel to assist relevant personnel in performing clear operations, braking and controlling corresponding equipment or operating modes, and improving processing efficiency. Due to targeted operations, the number of relevant personnel required can also be reduced, production efficiency can be improved, and differentiated handling of different scenarios can be achieved, improving the flexibility and reliability of handling.

[0154] In case B2, the monitoring device associated with the alarm device can be determined in the following way: Figure 7a The following steps:

[0155] S701: Obtain the identification of the alarm device.

[0156] The implementation method of this step can refer to step S201 and will not be repeated here.

[0157] S702: Determine the model location information of the alarm device in the BIM model according to the identifier of the alarm device and the BIM model.

[0158] Since the corresponding relationship between an entity and the entity in the model is preset in the BIM model, the model position information of the alarm device in the BIM model can be determined according to the identification of the alarm device and the BIM model.

[0159] S703: Determine a first monitoring device set according to the model position information and the visible area information of each monitoring device.

[0160] Since each monitoring device has its own visible area information, at least one monitoring device that meets the conditions can be determined to be the first monitoring device set according to the model location information and the visible area information of each monitoring device. The monitoring devices in the first monitoring device set may be on the same floor as the alarm device.

[0161] S704: Using the preset device spatial relationship, select at least one monitoring device from the first monitoring device set as a monitoring device associated with the alarm device.

[0162] Figure 7bA schematic diagram of a camera automatic search mechanism provided in an embodiment of the present application. The device spatial relationship is pre-set according to the positional relationship between entities, so that at least one monitoring device can be selected from the first monitoring device set as a monitoring device associated with the alarm device by using the pre-set device spatial relationship.

[0163] In this process, the space where the alarm device is located is used as the source, and devices that are not in the same space are eliminated, which can avoid monitoring devices with deviations due to wall problems. However, if the number of monitoring devices that meet the conditions is 0, the space wall problem is not considered, and the monitoring devices in the first monitoring device set are filtered to obtain the monitoring devices associated with the alarm device.

[0164] Since the video quality may be affected by factors such as light, weather and shooting angle, the accuracy of video analysis is reduced, resulting in false alarms. The camera recognition algorithm provided in the embodiment of the present application can accurately and automatically match cameras without manual search and review, improve the convenience of use, and realize intelligent scene processing.

[0165] The embodiment of the present application proposes to automatically form a handling process according to the event type. First, before the security event is reported to the system, an event analysis mechanism is introduced (to determine whether it is a pre-processing event or a scene handling event). The location information provided by the BIM and wireless Bluetooth positioning system is used to determine the authenticity of the security event identification and reduce false alarms. A pre-judgment and handling page is provided for certain types of security scenarios to improve the timeliness of user handling. In scene handling, the equipment and personnel location information is used to automatically find the equipment and personnel that need to be issued, and the actions are automatically handled, which effectively reduces the untimely and inaccurate problems caused by manual judgment and improves the efficiency of scene execution. Reduced personnel costs, equipment costs, loss costs and emergency plan costs.

[0166] refer to Figure 8a Next, we will use a specific example to illustrate the handling process of customer injury security incidents:

[0167] A. The video analysis system identifies a passenger injury type security event and reports the information to the event analysis system. The analysis system uses the device coordinate data provided by the BIM model to find the surrounding cameras and play real-time video.

[0168] B. The system pops up a scene prediction and disposal page. After the staff identifies the alarm screenshot and real-time video, they can control the equipment immediately (this is the predicted action). At the same time, the system automatically finds nearby staff based on the personnel coordinates provided by the wireless positioning system and notifies them to go to the scene to continue disposal.

[0169] Figure 8b A scenario operation diagram of a passenger injury security incident provided in an embodiment of the present application.

[0170] C. When a passenger is found injured on site, the duty room staff is notified to trigger the passenger injury handling scenario, and the system enters the passenger injury handling sub-scenario. In the passenger injury handling process, the duty officer reports the incident according to the process, instructs the operator to dial 120, and other actions.

[0171] D. After confirming that the on-site processing is completed and all equipment settings have returned to normal, report to the vehicle control room and notify all positions to resume normal operations.

[0172] In summary, the embodiments of the present application improve the efficiency and accuracy of security event handling, reduce the number of false alarms of security events, achieve low error, and accurately trigger scene handling. The pre-handling method when a security event involving injury to personnel occurs can reduce injuries to personnel and avoid secondary injuries.
