Description
Technical field
The invention belongs to metro passenger flows to guide field, and in particular to a kind of subway shield hanger-on based on intensity of passenger flow estimation
Flow guidance system.
Background technique
As Subway Network in China is improved day by day, more and more people start selection and take subway trip.In metro passenger flow
Biggish city is measured, the congestion of subway platform happens occasionally.Since the enter the station distribution in channel of subway cannot take into account all stations completely
Platform, crowd tends to collect in be needed to alleviate passenger flow congestion bring security risk to passenger flow close to the position of platform entrance
Effectively guided.
There are mainly two types of current passenger flow guidance methods, and one is static passenger flow guiding mark is puted up, guidance passenger is certainly
For row far from platform inlet, another kind is manually to guide, and arranges a certain number of staff to carry out passenger flow in platform and dredges.It is existing
Some methods cannot effectively guide passenger flow, and static passenger flow guiding mark can only be guided to fixed-direction, and artificial guiding can only
Guide the passenger flow near staff, can not carry out global overview and effectively guiding to subway concourse entirety passenger flow, and cost of labor compared with
It is high.
Summary of the invention
Goal of the invention: for the deficiency of current subway platform passenger flow guidance method, in conjunction with subway to the stringent of safe operation
It needs, platform entirety passenger flow is effectively guided.
Technical solution: to solve foregoing invention purpose, the present invention provides a kind of subway shield based on intensity of passenger flow estimation
Hanger-on flows guidance system, including video acquisition camera, information display terminal, control server, metro operation signal picker.
Told video acquisition camera and information display terminal are integrated on subway shield door, the video acquisition camera, information exhibition
Show that terminal, control server and metro operation signal picker are interconnected by the network switch.

Control server communication, real-time exhibition platform Trip distribution situation shows that content includes that passenger flow thermodynamic chart, passenger flow guiding suggest, are wide
Accuse information.
The network switch is used for the network connection of video acquisition camera, information display terminal, control server.
The control server is the X86 server of integrated high-performance calculation video card, includes intensity of passenger flow Estimation Software, visitor
Flow point analysis and guiding software and middle control management software.The intensity of passenger flow Estimation Software is for receiving high-definition camera real-time video
The hard solution of real time video data estimates the crowd density in picture at picture, and saves estimated result by data；It is described
Passenger flow analysing and guiding software are used to analyze the crowd density data in platform before all shield doors, issue and guide to each terminal
Control information.Middle control management software the managing and controlling for high-definition camera and information display terminal, takes the photograph comprising described
As the equipment state of head and terminal is checked, functional configuration.
The metro operation signal picker is used to obtain the subway train signal out of the station, tight of subway circulation system sending
Anxious control signal, system time service information.
Further, the video flow host-host protocol of the video acquisition camera is RTSP agreement, and video code model can
Are as follows: H.265/H.264/MPEG4/MJPEG.
Further, the processor that the information display terminal uses can be the embedded processing of the frameworks such as ARM or ATOM
Device；Internetwork connection mode can be the modes such as RJ45 twisted pair, WIFI.
Further, each information display terminal independently shows different guidance information.
Further, the information display system software uses C/S architecture design, with the control server communication protocol
It include: HTTP/TCP/TLS/UDP.
Further, the network switch supports RJ45 twisted pair and WIFI wireless access way.
Further, the high performance video cards that the control server uses is NVIDIA video cards.
Further, the video that the intensity of passenger flow Estimation Software uses solves method firmly as NVIDIA Video Codec
SDK；The crowd density estimation algorithm is the depth net model methodology based on CNN.
Further, the middle control management software uses B/S architecture design, provides web page access service, for station pipe
Historical data and analysis structure are checked in reason personnel access.
In order to realize goal of the invention, the present invention also provides a kind of visitors based on intensity of passenger flow distribution using above-mentioned facility
Guidance method is flowed, specifically:
The passenger flow analysing is with guiding software to the analysis of intensity of passenger flow estimation before all shield doors of platform as a result, can be divided into
Passenger flow is less, passenger flow is more, without three kinds of states of passenger, is shown respectively to each information according to the passenger flow state before each shield door
Terminal issues guidance information.
When the passenger flow analysing with guiding software to the analysis of passenger flow the result is that passenger flow is less, when without guiding or ground
Vehicle-state is when having entered the station in iron operation signal acquiring system, and information display terminal shows this train arrival situation and next
Train arrival time, or play advertising information.
When the passenger flow analysing with guiding software to the analysis of passenger flow the result is that passenger flow is more, when needing to guide, to each
Information display terminal sends passenger flow and guides relevant information, and each information terminal shows platform Trip distribution thermodynamic chart and locating screen
The position of door is covered, and provides suggestion passenger's direction of travel.
For preferably energy conservation, when passenger flow analysing and guiding software to the analysis of passenger flow the result is that when there is no passenger, information
Displaying terminal will enter energy-saving mode, including show static images, reduce screen intensity, dormancy information displaying software.
The utility model has the advantages that subway shield door passenger flow guidance system provided by the invention, can be according to each shield door of platform before
Passenger flow quantity precisely effective guiding image information is provided, while can show that platform and vehicle more abundant are believed to passenger
Breath, is conducive to metro safety operation.
