Description

Technical Field

[0001] The invention relates to a rail transit passenger flow diversion system, method, device and storage medium, belonging to the technical field of urban rail transit. Background Art

[0002] Urban rail transit is the backbone of urban public transportation. It is energy-saving, land-saving, large-capacity, all-weather, pollution-free (or less pollution) and safe. It is a green and environmentally friendly transportation system, especially suitable for large and medium-sized cities. The construction of urban rail transit in my country is accelerating, and urban rail transit has become the main daily transportation mode for people in many cities.

[0003] At present, the number of passengers in urban rail transit is increasing, but during peak hours, we can only rely on road signs and station staff to guide passenger flow to ensure the relative smoothness and safety of passenger passages. In multi-line transfer stations, the passenger density is greater and the management of station staff is more complicated, which brings greater safety risks to the operation of rail transit, and the passenger service experience is also relatively poor. Summary of the invention

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a rail transit passenger flow diversion system, method, device and storage medium, which control the AFC system and PA / PIS system in the station to perform passenger flow diversion according to the passenger flow density in the transfer area, thereby ensuring the relative smoothness and safety of the passenger passage, reducing the management difficulty of station staff, eliminating the operational risks of rail transit, and improving the passenger experience.

[0005] To achieve the above object, the present invention is implemented by adopting the following technical solutions: In a first aspect, the present invention provides a rail transit passenger flow diversion method, comprising: Get the passenger flow density of the transfer entrance area of ​​this station; Compare the passenger flow density in the transfer area of ​​the station with the preset threshold; In response to the passenger flow density in the transfer area of ​​the station exceeding the preset threshold, a control instruction is sent to the AFC system and PA / PIS system in the station to perform passenger flow diversion operations, otherwise the passenger flow diversion operations are not performed.

[0006] Furthermore, the passenger flow density is obtained by collecting video of each monitoring area through a video monitoring service installed in the station, and then detecting human body shape targets in the area through a video analysis service.

[0007] Furthermore, the video analysis service uses computer vision based on OpenPose's human pose estimation technology to detect human morphological targets in the area.

[0008] Furthermore, when the video analysis service detects that the population density detection identifier of a certain area is inconsistent with the cache of the population density detection identifier of the area, the area identifier, passenger flow direction identifier and passenger flow density are pushed to the passenger management service, and the cache of the population density detection identifier of the area is changed at the same time.

[0009] Furthermore, in response to the passenger flow density in the transfer area of ​​the station exceeding the preset threshold, a control instruction is sent to the AFC system and PA / PIS system in the station to conduct passenger flow diversion, including: In response to the passenger flow density of area 1 in the station exceeding a preset threshold, determining whether area 1 is a terminal area according to the area identifier of area 1; In response to the fact that area 1 is the terminal area, a control instruction is sent to the AFC system according to the passenger flow direction mark of area 1 to close the gate leading to area 1 in the same direction; In response to the fact that area 1 is a non-terminal area, judging whether the passenger flow density of the subsequent area in the direction at the same time exceeds a preset threshold according to the passenger flow direction mark of area 1; In response to the passenger flow density in the rear area being less than a preset threshold value at the same time, a control instruction is sent to the AFC system to close the gate leading to the transfer entrance in the area, and a control instruction is sent to the PA / PIS system to broadcast the excessive passenger flow density in the area and the direction and location information of the congested area; In response to the passenger flow density in all areas exceeding the preset threshold, a control instruction is sent to the AFC system to close the gates leading to the head-end area until an area with a passenger flow density within the operable range appears. A control instruction is sent to the AFC system to simultaneously open the gates leading to the transfer entrances and the gates leading to the head-end area in these areas, and a control instruction is sent to the PA / PIS system to broadcast the passable broadcasts in these areas and the direction and location information of the passable areas.

[0010] Furthermore, the passenger management service comprehensively predicts the passenger flow density of each platform door after the train arrives by receiving the passenger flow density in the carriages of the previous station and the arriving train, and sends control instructions to the AFC system in the station to control the opening and closing of each transfer channel gate according to the passenger flow density of each platform door, sends control instructions to the PA system in the station to broadcast information, and sends control instructions to the PIS system in the station to broadcast the passenger flow situation in each area in real time.

[0011] Furthermore, the types of transfer entrance areas include platform doors, escalator entrances, staircase entrances and vertical ladder entrances.

[0012] In a second aspect, the present invention provides a rail transit passenger flow management system, comprising: Data receiving module: obtain the passenger flow density in the transfer area of ​​the station; Data comparison module: compares the passenger flow density of the transfer entrance area of ​​the station with the preset threshold; Diversion and handling module: In response to the passenger flow density in the transfer area of ​​the station exceeding the preset threshold, control instructions are sent to the AFC system and PA / PIS system in the station to perform passenger flow diversion and handling, otherwise the passenger flow diversion and handling operation will not be performed.

[0013] In a third aspect, the present invention provides a rail transit passenger flow management device, including a processor and a storage medium; The storage medium is used to store instructions; The processor is used to operate according to the instructions to execute the steps of any of the methods described above.

[0014] In a fourth aspect, the present invention provides a computer-readable storage medium having a computer program stored thereon, which implements the steps of any of the above methods when executed by a processor.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention analyzes and counts regional passenger flows, and then derives passenger flow diversion strategies based on passenger flow density in each area, automatically links passenger flow dispersion equipment, and diverts passenger flow in real time and effectively. This method can be directly migrated and applied to stations that have built standard ISCS systems. After being applied to other stations, only the database configuration needs to be modified without modifying the program. This solves the problem in the prior art that emergency response capabilities are limited by manual diversion methods. This method uses the system's real-time automatic detection and automatic equipment linkage instead of the original manual passenger flow diversion method through fixed-point scheduling of on-duty personnel, which greatly improves the coverage and timely response capabilities of emergency response, with obvious results.

[0016] Second, the present invention solves the problem of multi-point accumulation of passengers caused by the lack of effective passenger diversion measures. With this method, the accumulation of passenger flow at the station will be greatly reduced, and the system will automatically respond in time after passenger flow accumulation occurs, and apply the passenger flow dispersion strategy to the corresponding area, greatly reducing the safety hazards caused by long-term passenger flow accumulation.

[0017] 3. The present invention solves the problem of passenger information sharing in multiple stations. With this method, stations can know in advance the distribution of passengers in the trains that are about to arrive, and apply the passenger flow dispersion strategy to the corresponding areas in advance, making passenger travel more comfortable and efficient. This greatly improves the passenger experience and potentially increases the benefits of subway operations. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0019] The present invention will be described in detail below with reference to the accompanying drawings and in combination with embodiments. It should be noted that the embodiments and features in the embodiments of the present invention can be combined with each other without conflict.

[0020] The following detailed description is an exemplary description, which is intended to provide further detailed description of the present invention. Unless otherwise specified, all technical terms used in the present invention have the same meaning as those generally understood by those skilled in the art to which the present invention belongs. The terms used in the present invention are only for describing specific embodiments, and are not intended to limit the exemplary embodiments according to the present invention.

[0021] Embodiment 1: See also Figure 1-2 This embodiment proposes a rail transit passenger flow diversion method, which is implemented based on the general rail transit ISCS integrated monitoring platform. The system is divided into four layers, namely the equipment layer, access layer, data processing layer and display layer. The functions and collaboration methods of the software and hardware at each layer are as follows: 1. Equipment layer The equipment layer mainly includes gates in the AFC system, camera equipment in the CCTV system, and broadcasting equipment in the PA and PIS systems. Its core work is to receive and execute control instructions issued by the passenger management service, complete the opening and closing operations of the gates, and broadcast the video and audio of passenger flow density information.

[0022] The equipment layer is the infrastructure for passenger dispersal. The station needs to coordinate the construction of passenger dispersal facilities in the corresponding areas according to the distribution of platform doors, transfer passages (including escalators, vertical ladders and stairs) and station hall ticket entrances, including gates, cameras, passenger isolation fences, broadcast speakers, and information broadcast screens. The specific working methods are as follows: 1. The video analysis service obtains the video stream information of the cameras in each monitoring area in real time and analyzes and counts the regional passenger flow. When the analysis finds that the passenger flow in a certain transfer area is too dense (the passenger flow density in the area exceeds the preset threshold), the passenger flow density of the subsequent area in the same direction at the same time is compared according to the monitoring area number.

[0023] 2. If the area is not the terminal area and there is a rear area with low passenger flow density, close the gate leading to the transfer entrance in the area, broadcast the excessive passenger flow density in the area and the direction and location information of the congested area, and guide passengers to pass through the gate in the rear area. If the area is the terminal area, close the gate leading to the area in the same direction to prevent passengers from continuing to move to the area.

[0024] 3. If the passenger flow in all areas is too dense, close the gates leading to the head-end area until an area with passenger flow density within the operable range appears. At the same time, open the gates leading to the transfer entrances and the gates leading to the head-end area in these areas, and broadcast the passable broadcasts of these areas and the direction and location information of the passable areas.

[0025] 2. Access Layer The access layer mainly includes the front-end processor FEP, ISCS interface service and video surveillance service.

[0026] The services work as follows: 1. The front-end processor FEP is used for data collection and pre-processing of each system at the equipment layer. It collects points needed in the AFC, PA, and PIS systems, such as the local / remote points and remote control points of the AFC gate, and the information sending points of PA and PIS, and logically converts multiple related points into calculation points for the convenience of subsequent service use.

[0027] 2. The ISCS interface service is used to collect the point data of each system equipment layer after secondary processing from the front-end processor, and register the point data in the ISCS system as a SCADA node, and provide it to the business system service.

[0028] 3. Video surveillance services are used for video collection, storage and terminal equipment management in various surveillance areas of the station, and provide basic analysis conditions and data for video analysis services.

[0029] 3. Data Processing Layer The data processing layer mainly includes passenger management services and video analysis services. It is the core layer of the system and the logical center of the entire passenger flow management system. The working methods of each service in the data processing layer are as follows: 1. Database services are mainly used for the storage and data services of structured data, including system configuration, real-time status of passenger flow density, decision-making results, command issuance operation information and other data.

[0030] 2. The video analysis service mainly uses computer vision and OpenPose-based human posture estimation technology to detect human body shape targets in the area. When it is analyzed that the population density in a certain area is greater than the set threshold, and the cache of the population density detection mark in the area is normal, the area mark, passenger flow direction mark and passenger flow density are pushed to the passenger management service, and the cache of this population density detection mark is set to alarm. When it is analyzed that the population density in a certain area is within the normal threshold range, and the cache of the population density detection mark in the area is an alarm, the area mark, passenger flow direction mark and population density monitoring status are pushed to the passenger management service, and the cache of this population density detection mark is set to normal. The purpose of this is to reduce the interaction of video analysis data to avoid unnecessary waste of network bandwidth.

[0031] 3. Passenger management services mainly rely on the ISCS system and video surveillance system basic data, including gates, broadcasts, PIS screens, cameras, transfer areas, etc., to structure the discrete data of the station and highly correlate them together. The intelligent analysis results of video data using video analysis can effectively control passenger flow. The service is mainly divided into the following components: ①Configuration management components This component is used to manage the associated configuration information of all physical devices and virtual identifications involved in the system. Physical devices include gates, broadcasts, PIS screens, cameras, etc., and virtual identifications include passenger flow areas, transfer gate numbers, passenger flow directions, etc. The component provides a configuration information management interface for station staff to perform configuration addition, deletion, modification, and query operations to cope with changes in equipment information caused by the transformation of station-related systems.

[0032] ②Database components This component is used to persistently store configuration, real-time status of passenger flow density, decision-making derivation results, command issuance operation information, etc. It provides function interfaces to add, delete, modify, and query configuration information, and add new operations to real-time status of passenger flow density, decision-making derivation results, and command issuance operations. It records operation events to facilitate subsequent tracing of important equipment actions.

[0033] The database structure managed by this component: The basic configuration information includes: Transfer gate information, including transfer gate number, transfer gate type (platform door / escalator gate / staircase gate / vertical staircase gate), transfer gate location, and transfer gate name; Passenger flow area information, including area number, passenger flow direction, and transfer gate; Passenger flow threshold information, including the area to which it belongs and the passenger flow density threshold; Camera information, including camera number, camera location (in-station / on-board), and passenger flow area analyzed; Gate information, including gate number, gate location, passenger flow area, and destination (transfer gate / passenger flow area); PA broadcast, including broadcast equipment number and passenger flow area; PIS screen, including screen number and passenger flow area; Video analysis information includes: Passenger flow density status, including camera number, passenger flow density status, and occurrence time; Decision-making information includes: Derivation result information, including derivation number, derivation time, and whether a control command needs to be issued; Control command information, including the device type, device number, control command, and issuing time; ③Data interface components This component is used to provide a lightweight REST service interface for the video analysis service to report the alarm of the personnel density detection. When the component receives the area identification, passenger flow direction identification and personnel density detection status message, it parses and filters the message. If it conforms to the passenger flow density status information protocol structure, the information is saved to the database through the database component. Then it is pushed to the decision deduction component for logical deduction of the passenger flow diversion decision in the same direction area.

[0034] ④SCADA operation components This component is used to issue the control commands to gates, broadcasting and PIS devices derived by the decision-making deduction component. Before issuing the commands, it is necessary to judge the status of some important equipment, such as the remote / local status of the gate, to ensure single control of the equipment and avoid dangers such as people being pinched by the gate.

[0035] ⑤Decision-making inference component This component is used to logically deduce the passenger flow density status of all areas in the same direction, so as to decide the operations that should be performed by all gates, broadcasting equipment, and PIS screen equipment in that direction. Then the control operation command is issued through the SCADA operation component, and the operation record is saved to the database through the database component at the same time.

[0036] The core logic of this component is: According to the passenger density status of all areas in this direction, if there is a passenger density alarm area, analyze the passenger density alarm area one by one. If the area is a non-terminal area and there is a rear area with low passenger density, close the gate leading to the transfer entrance in the area, broadcast the excessive passenger density broadcast and the direction and location information of the congested area in the area, and guide passengers to pass through the gates in the rear area. If the area is a terminal area, close the gates leading to the area in the same direction to prevent passengers from continuing to move to the area. If the passenger flow status of all areas in this direction is an alarm, close the gates leading to the head end area until an area with normal passenger density appears, and open the gates leading to the transfer entrance and the gates leading to the head end area in these areas at the same time, and broadcast the passable broadcasts and the direction and location information of the passable areas in these areas.

[0037] 4. Display Layer The display layer mainly includes ISCS workstations and passenger management terminals. They mainly complete the following tasks: 1. ISCS is used to display the status of each device and the maintenance of the video surveillance system. It assists in viewing the video recordings of the video surveillance points in each passenger flow area, making it convenient for station staff to confirm the passenger flow status of each area.

[0038] 2. The passenger management terminal is mainly provided for maintenance personnel to use, which can modify the system's global basic configuration information, preview video analysis results information and preview operation events.

[0039] This embodiment proposes solutions to the following three problems: 1. Solve the problem of small coverage of manual passenger flow diversion and limited emergency response capabilities. Station staff guide passenger flow through fixed-point scheduling of on-duty personnel, and the coverage of time and space is relatively small. In addition, when there is an occasional large passenger flow, there will be no on-duty personnel to conduct diversion in time. It is necessary to wait until the patrol personnel discover it before notifying the station service and organizing personnel to divert the passenger flow, and the emergency response capability is greatly limited. This embodiment uses intelligent video analysis to analyze the passenger flow density in the passenger open area of ​​the station, and transmits the analysis results to the passenger management service. When the regional passenger flow density exceeds the pre-set passenger flow congestion threshold, the passenger management service automatically links the station's AFC system and PA / PIS system according to the passenger flow congestion area to achieve rapid passenger flow diversion and disposal.

[0040] Second, solve the problem of multiple accumulation of passengers, no reasonable passenger flow dispersion setting, and increased safety hazards. The transfer passage between the subway station hall and the platform often presents an uneven distribution of passengers due to the different population densities of each subway entrance, which often causes accumulation of passengers in some areas and few passengers in some areas. However, the current subway operation has not made a response strategy for this. It depends entirely on the subjective will of passengers to choose the nearest transfer passage, and no passenger density information of each transfer port is provided to passengers in advance. The safety hazard of passenger accumulation always exists, and this hazard is more prominent when the station has a large passenger flow. For the areas with frequent passenger accumulation points in daily operation of the station, this embodiment adds gates and isolation fences, and uses intelligent video analysis to count the passenger flow in each area in real time. When there is a large accumulation of passenger flow in some areas, some gates are closed by linkage with the AFC system to prevent the passenger flow from continuing to move to the accumulation point. Then open the gate leading to the passenger transfer area without accumulation to guide passengers to move to these areas. Automatically divert passenger flow and reduce safety hazards.

[0041] 3. Solve the problem of lack of passenger information at nearby stations and no effective pre-control capabilities. At present, rail transit operations provide very little auxiliary management information between stations, and there is almost no relevant passenger flow, which leads to relatively closed passenger flow information at stations, and nearby stations cannot make advance arrangements for passenger services and can only deal with them on a case-by-case basis. Such event-based services greatly reduce the quality of passenger services and cannot give full play to the passenger service capabilities of rail transit in a more comfortable, efficient and technological way. This embodiment comprehensively predicts the passenger flow that is about to arrive by receiving video analysis statistics of the passenger flow conditions at each platform of the previous station, and receiving video analysis statistics of the passenger flow conditions in the carriage of the train that is about to arrive. According to the predicted passenger flow density of each platform door, the opening and closing of each transfer channel gate are intelligently linked, and information is broadcast through the PA system. The PIS system plays the passenger flow conditions in each area in real time, so that passengers getting on and off the train can pass under a relatively balanced passenger flow density. Intelligently and effectively improve the passenger experience.

[0042] Take a subway station application as an example. Figure 3 This is a software and hardware deployment diagram, where the passenger management service is deployed on the passenger management server, the database service is deployed on the database server, the video analysis service is deployed on the video analysis server, and the fusion interface is deployed on the passenger management terminal for station operators to use. The passenger management terminal is mainly provided for maintenance personnel to use, and can modify the system's global basic configuration information, preview video analysis results information, and preview operation events.
