Facing the passenger flow of tens of millions of rail transit vehicles, the on-vehicle information perception system of rail transit vehicles is particularly important. The on-vehicle information perception system of rail transit vehicles can provide information services for passengers through display terminals and audio terminals.

[0048] The embodiments of the present application will be described below with reference to the accompanying drawings. Those skilled in the art will know that with the development of technology and the emergence of new scenarios, the technical solutions provided by the embodiments of the present application are equally applicable to similar technical problems.

It should be understood that such terms can be interchanged under appropriate circumstances, which is only a way of distinguishing when describing objects with the same attributes in the embodiments of the present application. In addition, the terms "comprising" and "having" and any variations thereof are intended to cover non-exclusive inclusion, so that a process, method, system, product or device comprising a series of units does not have to be limited to those units, but may include other units not clearly listed or inherent to these processes, methods, products or devices.

[0050] In order to improve the comprehensive perception ability of on-vehicle information of rail transit vehicles, the present application provides a method for perceiving on-vehicle information of rail transit vehicles. The method for perceiving on-vehicle information of rail transit vehicles provided by the present application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0051] Please refer to the attached Figure 1 , Figure 1 which is a schematic flow chart of a method for perceiving on-vehicle information of a rail transit vehicle provided by an embodiment of the present application. This method is applied to an on-vehicle information perception system of a rail transit vehicle. The system includes: a target perception control host, a target edge computing server, at least one switch, a video acquisition terminal, an environment acquisition terminal, a target driver's cab control host, a passenger compartment control host in at least one passenger compartment, an audio terminal, and a display terminal;

[0052] For ease of understanding, reference can be made to Figure 2 , Figure 2 which is a schematic structural diagram of an on-vehicle information perception system of a rail transit vehicle disclosed in an embodiment of the present application.

[0053] It should be noted that the switch is respectively communicatively connected to the target perception control host, the target edge computing server, the video acquisition terminal, and the environment acquisition terminal; the passenger compartment control host is respectively communicatively connected to the target driver's cab control host, the display terminal, and the audio terminal; the target driver's cab control host is communicatively connected to the target perception control host.

[0054] Among them, the target perception control host is determined from two perception control hosts; the target edge computing server is determined from two edge computing servers; the target cab control host is determined from two cab control hosts; the target monitoring touch screen is determined from two monitoring touch screens.

[0055] The target perception control host, the target edge computing server, at least one switch, the video acquisition terminal, and the environment acquisition terminal are deployed through Ethernet of the cab control host, the audio terminal, and the display terminal in at least one passenger compartment relying on the target cab control host. The target cab control host and the target perception control host can communicate with each other in the form of UDP multicast.

[0056] Such as Figure 1 shown, the method may include the following steps:

[0057] Step S101: For each passenger compartment of the rail transit vehicle, the target perception control host controls the video acquisition terminal to collect the passenger behavior information and passenger characteristic information of the passenger compartment through the switch, and controls the environment acquisition terminal to collect the environment information of the passenger compartment through the switch.

[0058] Before the target perception control host controls the video acquisition terminal to collect the passenger behavior information and passenger characteristic information of the passenger compartment through the switch, and controls the environment acquisition terminal to collect the environment information of the passenger compartment for each passenger compartment of the rail transit vehicle, the method may further include: Multiple cab control hosts obtain the activation information of the rail transit vehicle. The activation information includes the target monitoring touch screen number, the target cab control host number, the target perception control host number, and the target edge computing server number. The multiple cab control hosts send the activation information to the multiple monitoring touch screens so that the conductor can activate the target monitoring touch screen, the target cab control host, the target perception control host, and the target edge computing server. The monitoring touch screen number of the target monitoring touch screen is consistent with the target monitoring touch screen number, the cab control host number of the target cab control host is consistent with the target cab control host number, the perception control host number of the target perception control host is consistent with the target perception control host number, and the edge computing server number of the target edge computing server is consistent with the target edge computing server number.

[0059] It should be noted that rail transit vehicles usually have a symmetrical structure, which means that the two ends of rail transit vehicles are the same in design, and there is no fixed head car end and tail car end. This design allows rail transit vehicles to run in both directions without changing the head car or performing coupling operations at the turnaround station. However, this flexibility also brings about the problem of determining the direction of vehicle operation. Every time the on-board information perception system of a rail transit vehicle is started, it is necessary to clarify the current tail car end so that the driver at the tail car end of the rail transit vehicle can correctly perform various controls and management. The driver at the head car end of the rail transit vehicle only needs to be responsible for normal driving.

[0060] Among them, the tail car end corresponds to the activation information, so the driver's cab control host needs to obtain the activation information from the train network system to ensure the correct operation of the on-board information perception system of the rail transit vehicle and the safe operation of the rail transit vehicle. The activation information includes the target monitoring touch screen number, the target driver's cab control host number, the target perception control host number and the target edge computing server number. These numbers are used to uniquely identify each device and component in the on-board information perception system of the rail transit vehicle. After the driver receives these activation information through the monitoring touch screen, the corresponding device will be activated according to the number matching principle. Only when the number of the monitoring touch screen is consistent with the target monitoring touch screen number, the number of the driver's cab control host is consistent with the target driver's cab control host number, the number of the perception control host is consistent with the target perception control host number, and the number of the edge computing server is consistent with the target edge computing server number, these devices will be successfully activated. This step ensures that only correctly configured and authorized devices can participate in the subsequent information collection and processing process, thereby ensuring the safety and reliability of the on-board information perception system of the rail transit vehicle.

[0061] When both ends of a rail transit vehicle are not activated (such as the rail transit vehicle is not powered on) or one end is not activated (such as the leading end of a rail transit vehicle), the rail transit vehicle's own monitoring screen will be displayed by default, and the interior of the rail transit vehicle can still be monitored to provide support for the operation and management of the rail transit vehicle.

[0062] In this application, each passenger compartment of a rail transit vehicle corresponds to a set of switches, video acquisition terminals, and environment acquisition terminals. The target perception control host controls the video acquisition terminal through the switch to collect passenger behavior information and passenger feature information of each passenger compartment of the rail transit vehicle, and controls the environment acquisition terminal through the switch to collect environmental information of the passenger compartment.

[0063] Among them, the switch can realize data transmission and switching. The video acquisition terminal is usually a camera, which can not only be used to collect passenger behavior information and passenger characteristic information in the passenger compartment in real time, but also collect driver behavior information in the driver's cab through the video acquisition device in the driver's cab. The environment acquisition terminal is usually various sensors, which are used to monitor the environmental parameters in the passenger compartment (such as temperature, humidity, carbon dioxide concentration, etc.) in real time.

[0064] Step S102: The target perception control host sends the passenger behavior information and passenger characteristic information of each passenger compartment to the target edge computing server through each switch, so that the target edge computing server analyzes the passenger behavior information and passenger characteristic information of each passenger compartment respectively to obtain the warning information and crowding degree of each passenger compartment.

[0065] In this application, the switch plays the role of data exchange and routing in the network, which can ensure that data can be accurately transmitted from the acquisition terminal to the target edge computing server. In this application, the target perception control host transmits the collected data to the target edge computing server through each switch. The target edge computing server uses advanced image recognition and behavior analysis algorithms. By analyzing the passenger behavior information, it detects whether the passengers have abnormal behaviors, so as to obtain the warning information of each passenger compartment. Further, the target edge computing server uses advanced image recognition and behavior analysis algorithms. By analyzing the driver behavior information, it detects whether the driver has abnormal behaviors, so as to obtain the warning information of the driver's cab. It should be noted that each warning information includes a warning event. For the convenience of understanding, please refer to Table 1 specifically. Table 1 is as follows:

[0066] Table 1

[0067]

[0068] The target perception control host can use the UDP multicast method to send warning information to the target driver's cab control host in real time. The warning information is usually divided into different levels for easy management. The warning information not only includes the warning event, but also can include the passenger compartment number and the driver's cab number. During the transmission process, the warning information is transmitted in the form of data packets. Please refer to Table 2 specifically. Table 2 is as follows:

[0069] Table 2

[0070]

[0071] The target edge computing server uses advanced image recognition and feature analysis algorithms. By analyzing the passenger characteristic information, it identifies the number of passengers, and then determines the crowding degree of each passenger compartment. The crowding degree is usually divided into different levels for easy management.

[0072] The target perception control host can send the crowding degree and environmental information of the passenger compartments to the target driver's cab control host in the form of UDP multicast based on a preset period. During the transmission process, the formats and contents of the crowding degree and environmental information need to be standardized, and the crowding degree and environmental information of the passenger compartments are transmitted in the form of data packets. Specifically, reference can be made to Table 3 as shown below:

[0073] Table 3

[0074]

[0075] Step S103: The target driver's cab control host receives the warning information of each passenger compartment sent by the target perception control host, and sends the warning information of each passenger compartment to the audio terminals in each passenger compartment through the passenger compartment control host in each passenger compartment, so that the audio terminals in each passenger compartment broadcast the warning information of each passenger compartment.

[0076] After the target driver's cab control host receives the warning information of each passenger compartment sent by the target perception control host, the method may further include: The target driver's cab control host sends the warning information of each passenger compartment to the target monitoring touch screen, so that the conductor can determine the target warning information of each passenger compartment from the warning information of each passenger compartment through the target monitoring touch screen.

[0077] In this application, after the target driver's cab control host receives the warning information, it can also send this information to the target monitoring touch screen. The target monitoring touch screen is usually located in the driver's cab and is used by the conductor or the driver. The conductor can view the warning information of each passenger compartment through the target monitoring touch screen, including the location of the warning event, the picture of the warning event, etc. The conductor can determine the target warning information of each passenger compartment from the warning information of each passenger compartment according to the actual situation and experience through operations on the touch screen (such as clicking, swiping, etc.). This may involve prioritizing and screening multiple warning events. For example, if multiple warning events occur simultaneously, the conductor may give priority to handling the passenger commotion event and rank the event of not wearing a mask behind.

[0078] At this time, the target driver's cab control host sends the target warning information of each passenger compartment to the audio terminals in each passenger compartment through the passenger compartment control host in each passenger compartment, so that the audio terminals in each passenger compartment broadcast the target warning information of each passenger compartment.

[0079] The target driver's cab control host sends the target warning information of each passenger compartment to the audio terminals in each passenger compartment through the passenger compartment control host in each passenger compartment according to the conductor's selection. After receiving the target warning information, the audio terminal broadcasts it to ensure that passengers can hear the relevant warning prompts in time. For easy understanding, specifically, reference can be made to Table 4 as shown below:

[0080] Table 4

[0081]

[0082] Specifically, the target warning information for each passenger compartment includes the target passenger compartment number and the target warning event. The target driver's cab control host determines the target passenger compartment from each passenger compartment, and sends the target warning event to the audio terminal in the target passenger compartment through the passenger compartment control host in the target passenger compartment, so that the audio terminal in the target passenger compartment broadcasts the target warning event, and the passenger compartment number of the target passenger compartment is the same as the target passenger compartment number.

[0083] It should be noted that the target warning information for each passenger compartment includes the target passenger compartment number and the target warning event. The target passenger compartment number is used to identify a specific passenger compartment, and the target warning event describes the specific warning situation in that passenger compartment.

[0084] In this application, the target driver's cab control host determines the target passenger compartment from each passenger compartment, which is usually based on the location where the warning event occurs. The warning event occurs in a specific passenger compartment, and this passenger compartment is the target passenger compartment. After determining the target passenger compartment, the target warning event is sent to the audio terminal in this passenger compartment through the passenger compartment control host in the target passenger compartment.

[0085] Among them, the broadcast of the target warning event is set to the lowest priority, which means that when it coexists with other broadcast prompts (such as station broadcasts), it will wait for other higher-priority broadcasts to finish playing before playing the target warning event, so as to ensure the normal broadcast order of rail transit vehicles and avoid the chaos and interference of broadcast information.

[0086] Step S104: The target driver's cab control host receives the congestion degree and environmental information of each passenger compartment sent by the target perception control host based on a preset period, and sends the congestion degree and environmental information of each passenger compartment to each display terminal through the passenger compartment control host of each passenger compartment, so that each display terminal displays the congestion degree and environmental information of each passenger compartment.

[0087] After the target driver's cab control host receives the congestion degree and environmental information of each passenger compartment sent by the target perception control host based on a preset period, the method may further include the following steps: The target driver's cab control host sends the congestion degree and environmental information of each passenger compartment to the target monitoring touch screen, so that the target monitoring touch screen displays the congestion degree and environmental information of each passenger compartment.

[0088] In this application, in a rail transit vehicle, the target driver's cab control host is responsible for receiving and processing the congestion degree and environmental information of each passenger compartment from the target perception control host, and sending this information to each display terminal and the target monitoring touch screen to achieve real-time display and monitoring of information.

[0089] It should be noted that the congestion levels of each passenger compartment can be divided into three levels (1 - 3) according to the number of passengers and displayed in four colors (green, yellow, red). For example: green (0 - 50 people), yellow (51 - 100 people), red (151 people and above). For the convenience of understanding, specific reference can be made to Figure 3 , Figure 3 which is a schematic diagram of the congestion level of each passenger compartment provided by an embodiment of this application. The environmental information of each passenger compartment mainly displays the specific values of environmental parameters such as temperature, humidity, PM2.5, and CO2 concentration.

[0090] The display terminal receives the congestion levels and environmental information of each passenger compartment from the control host in the driver's cab and performs comprehensive display. Passengers can understand the congestion situation and environmental conditions of each passenger compartment in real time through the display terminal, so that passengers can choose relatively less crowded and more comfortable compartments according to the congestion level information, improving the riding comfort.

[0091] After the target monitoring touch screen receives the congestion levels and environmental information of each passenger compartment from the control host in the target driver's cab, it displays them in a detailed and intuitive manner. The conductor can view the specific data of each passenger compartment through the touch screen for necessary management and adjustment.

[0092] In summary, an on - vehicle information perception method for a rail transit vehicle provided by this application is applied to the on - vehicle information perception system of a rail transit vehicle. The system includes: a target perception control host, a target edge computing server, at least one switch, a video acquisition terminal, an environmental acquisition terminal, a target driver's cab control host, a passenger compartment control host, an audio terminal, and a display terminal in at least one passenger compartment. This method can obtain multi - dimensional information such as passenger behavior information, passenger characteristic information, and environmental information in real time by installing a video acquisition terminal and an environmental acquisition terminal in each passenger compartment of the rail transit vehicle, realizing a comprehensive perception of the internal situation of the rail transit vehicle. The target perception control host sends the collected information to the target edge computing server through the switch, and uses its powerful computing ability to perform real - time analysis on the passenger behavior information and passenger characteristic information, quickly generating early warning information and congestion levels. After receiving the early warning information, the target driver's cab control host broadcasts it through the audio terminals in each passenger compartment, enabling passengers to timely understand abnormal situations and improving the safety of the operation process of the rail transit vehicle. The target driver's cab control host sends the congestion levels and environmental information of each passenger compartment to the display terminal for display, and passengers can intuitively see the congestion degree and environmental conditions of each passenger compartment, which helps passengers reasonably select the position of the passenger compartment during the ride, ensuring the reasonable utilization of the space of the rail transit vehicle.

[0093] Based on the above-described embodiments disclosed in the present application, in another embodiment of the present application, a detailed description is given of the specific implementation manner after the target cab control host in step S104 receives the crowding degree and environmental information of each passenger compartment sent by the target perception control host based on a preset period, and sends the crowding degree and environmental information of each passenger compartment to each display terminal through each passenger compartment control host.

[0094] As an implementable manner, please refer to the attached Figure 4 , which is a schematic flowchart of a method for displaying the result of passenger evacuation analysis disclosed in the present application. The method may include the following steps:

[0095] Step S201: The target perception control host receives the passenger evacuation instructions of each passenger compartment sent by the target cab control host, and for each passenger compartment, based on the passenger evacuation instruction of the passenger compartment, controls the video acquisition terminal to collect the passenger characteristic information of the passenger compartment through the switch.

[0096] In the present application, after the last station door closing signal sent by the target cab control host, the passenger evacuation instructions of each passenger compartment are sent to the target perception control host. The target perception control host is responsible for managing and coordinating the intelligent devices in each passenger compartment. For each passenger compartment, the video acquisition terminal is controlled through the switch to collect the passenger characteristic information of the passenger compartment. Further, the item characteristic information of the passenger compartment can also be collected, such as the backpacks, mobile phones, etc. of the passengers.

[0097] Step S202: The target perception control host sends the passenger characteristic information of each passenger compartment to the target edge computing server through each switch, so that the target edge computing server performs passenger evacuation analysis on the passenger characteristic information of each passenger compartment to obtain the passenger evacuation analysis result.

[0098] In the present application, the target perception control host sends the passenger characteristic information of each passenger compartment to the target edge computing server through each switch. The switch plays a role in network connection and data transmission here, ensuring that the information can reach the edge computing server efficiently and accurately. The edge computing server is responsible for performing passenger evacuation analysis on the passenger characteristic information of each passenger compartment. Specifically, through image recognition technology, the video images collected by the camera can be analyzed to determine whether there are still stranded passengers in the carriage. Further, it can also be analyzed whether there are items that do not belong to the carriage equipment in the image, such as backpacks, mobile phones, etc. left by the passengers.

[0099] Step S203: The target perception control host sends the passenger evacuation analysis result to the target monitoring touch screen through the target cab control host, so that the target monitoring touch screen displays the passenger evacuation analysis result.

[0100] In this application, the target perception control host sends the passenger evacuation analysis result to the target monitoring touch screen through the target driver's cab control host. This process ensures that the passenger evacuation analysis result can reach the conductor's operation interface in a timely and accurate manner. The display content may include: information on stranded passengers: showing the location and image of stranded passengers; information on left items: showing the location, image, and possible item descriptions of left items; passenger evacuation status: showing the passenger evacuation status of each passenger compartment, such as "passenger evacuation completed" or "further inspection required".

[0101] In summary, the method for displaying the passenger evacuation analysis result provided by the embodiment of this application can quickly identify stranded passengers and left items through the target perception control host, switch, video acquisition terminal, and edge computing server, ensure that all passengers leave the carriage safely, avoid potential safety hazards caused by incomplete passenger evacuation, and reduce safety problems caused by left items.

[0102] Based on the above embodiments disclosed in this application, in another embodiment of this application, a specific implementation method for displaying the passenger flow information of each station is described in detail.

[0103] As an implementable manner, please refer to the attached Figure 5 , which is a schematic flowchart of the method for displaying the passenger flow information of each station disclosed in this application. The method may include the following steps:

[0104] Step S301: The target perception control host receives the passenger compartment door opening time points and passenger compartment door closing time points of each station of the rail transit vehicle sent by the target driver's cab control host, and for each station, through each switch, controls each video acquisition terminal to collect the passenger behavior information and passenger characteristic information of the station from the passenger compartment door opening time point of the station to the passenger compartment door closing time point of the station.

[0105] In this application, the target driver's cab control host is responsible for managing the operation status of the rail transit vehicle and can send the passenger compartment door opening and closing time points of each station to the target perception control host. The switch is used to connect the video acquisition terminal and the target perception control host to ensure efficient data transmission. After receiving the passenger compartment door opening time point and the passenger compartment door closing time point, for each station, starting from the passenger compartment door opening time point of the station, the target perception control host controls the video acquisition terminal (such as a camera) to collect the behavior (such as passing quickly, staying, returning, etc.) and characteristic information (such as face recognition or appearance recognition) of the passengers through each switch until the passenger compartment door closing time point of the station ends.

[0106] Step S302: The target perception control host sends the passenger behavior information and passenger characteristic information of each station to the target edge computing server through each switch, so that the target edge computing server analyzes the passenger behavior information and passenger characteristic information of each station to obtain the passenger flow information of each station.

[0107] In this application, the target perception control host sends the collected passenger behavior and characteristic information of each station to the target edge computing server through each switch, which ensures that the data can reach the analysis server quickly and accurately. The target edge computing server receives the data from the target perception control host. Through image recognition and behavior analysis technologies, based on the passenger behavior information of each station, it ensures the accuracy of statistics; through image recognition and feature analysis technologies, based on the passenger characteristic information of each station, it distinguishes different passengers to avoid double counting, and then statistically obtains the number of passengers getting on and off at each station, that is, the passenger flow information of each station. These information can be further used to analyze the passenger flow peak, passenger flow trend, etc. of the station.

[0108] Step S303: The target perception control host sends the passenger flow information of each station to the target monitoring touch screen through the target driver's cab control host, so that the target monitoring touch screen displays the passenger flow information of each station.

[0109] In this application, the target perception control host sends the passenger flow information of each station to the target monitoring touch screen through the target driver's cab control host, ensuring that the passenger flow information of each station can reach the conductor's operation interface in time. The target monitoring touch screen can display the passenger flow information of each station in an intuitive way. The display content can include: auxiliary information such as the number of passengers getting on and off at each station, station name, timestamp, etc. Further, it can be displayed graphically (such as bar chart, line chart) to more intuitively show the passenger flow change trend.

[0110] In summary, a method for displaying the passenger flow information of each station provided by this application can quickly calculate the passenger flow information of each station through the target perception control host, switch, video acquisition terminal and edge computing server. The passenger flow information can be recorded and analyzed to provide data support for long-term operation management. It is also convenient for the conductor to view the passenger flow situation of each station in real time through the monitoring touch screen and intervene when necessary.
