The following description will be given by taking an example of a method for executing the management and control of the passenger flow of the subway station by using the passenger flow line management and control device of the subway station. Referring to fig. 1, the method for managing and controlling passenger flow in a subway station includes:
s101: and determining a station passenger flow route based on passenger control nodes in the subway station.
The passenger control nodes are nodes for controlling passenger flow in the subway station, and include but are not limited to entrances and exits, passages (escalators, stairs and elevators) for going upstairs and downstairs, security check machines, gates, transfer passages, platforms and the like. It can be understood that different subway stations can arrange the types and the number of the corresponding passenger control nodes according to actual needs, for example, whether an elevator or an escalator is set can be selected according to the accommodation capacity of the subway station, or the number of gates or security check machines is set according to the passenger flow of the subway station. The transfer passage is used for transferring different subway lines in the same subway station and can also be used for transferring the same subway line in different directions.
Further, the station passenger flow routes include an inbound route taking the entrance and the exit and the platform as a starting point and an ending point, an outbound route taking the platform and the entrance and the exit as a starting point and an ending point, and a transfer route taking different platforms as a starting point and an ending point, wherein the inbound route, the outbound route and the transfer route are station passenger flow routes based on inbound, outbound and transfer directions in the subway station respectively. Generally, for a subway station, there are station passenger flow routes in the inbound and outbound directions, and a station passenger flow route in the transfer direction generally exists in a subway station where different subway lines are collected (for example, a certain subway station is a collection point of two or more subway lines, and then the subway station has the inbound route, the outbound route and the transfer route at the same time).
It can be understood that there may be a situation where the guest nodes are duplicated in the inbound route, the outbound route, and the transfer route, that is, the same guest node may be used as a node on multiple routes, and the guest node is passed by walking according to different routes. Further, the guest nodes passed by the inbound route, the outbound route and the transfer route are respectively defined as an inbound node, an outbound node and a transfer node.
Illustratively, after determining the passenger control nodes within the subway station, a plurality of station passenger flow routes in the inbound, outbound and/or transfer directions are determined based on the inbound nodes, outbound nodes and/or transfer nodes within the subway station. Specifically, in the station entering direction, a plurality of station passenger flow routes in the station entering direction are determined by taking an entrance and an exit and a platform as a starting point and an end point and by the combination of different station entering nodes; in the outbound direction, taking the platform and the entrance and exit as a starting point and an end point, and determining a plurality of station passenger flow routes in the outbound direction by the combination of different outbound nodes; in the transfer direction, a plurality of station passenger flow routes in the transfer direction are determined with the platforms of different railway lines as the starting point and the ending point, and with the combination of different transfer nodes. Further, after determining different station passenger flow routes, the station passenger flow routes can be stored in preset storage positions.
S102: and determining a shortest distance path based on the station passenger flow path, wherein the shortest distance path is the station passenger flow path with the shortest distance from the starting point to the end point.
Illustratively, after a plurality of station passenger flow routes in a subway station are determined, the moving distance of each station passenger flow route from a starting point to an end point is calculated, the moving distances of the station passenger flow routes corresponding to the same direction are compared, and the station passenger flow route with the shortest moving distance from the starting point to the end point is taken as the shortest distance route in the corresponding direction, so that the shortest distance routes in the entering, exiting and transferring directions are obtained. Generally, for one subway station, there are shortest distance paths in the inbound and outbound directions, and the shortest distance path in the transfer direction generally exists in subway stations where different railway lines converge.
The moving distance can be obtained by measuring the distance from the starting point to the end point of each station passenger flow route on site through a measuring instrument (distance meter), can be obtained by calculating the distance from the starting point to the end point of each station passenger flow route through a design drawing, and can be obtained by utilizing the distance measuring function of mobile equipment such as a mobile phone, a tablet and the like to hold the mobile equipment to move along each station passenger flow route so as to obtain the corresponding moving distance.
S103: and determining a shortest time path based on the station passenger flow path and the path passing time, wherein the shortest time path is the station passenger flow path which takes the shortest time from the starting point to the ending point.
Illustratively, after a plurality of station passenger flow routes in a subway station are determined, the moving time of each station passenger flow route from a starting point to a terminal point is calculated, the moving times of the station passenger flow routes corresponding to the same direction are compared, and the station passenger flow route with the shortest moving time is taken as the shortest time route in the corresponding direction, so that the shortest time routes in the entering, exiting and transferring directions are obtained. Generally, for one subway station, there will be the shortest time path in the inbound and outbound directions, and the shortest time path in the transfer direction will generally exist in subway stations where different railway lines converge.
The moving time can be determined by a face recognition camera device arranged in the subway station, for example, the time difference between the arrival of a plurality of passengers at the starting point and the ending point of the station passenger flow route is obtained, the mean value of the time difference is used as the moving time of the corresponding station passenger flow route, or the time spent by a worker in the movement of each station passenger flow route from the starting point to the ending point is used as the moving time, or the moving time can be calculated by estimating the passenger flow speed on each station passenger flow route and combining the moving distance of the corresponding station passenger flow route.
S104: and displaying the shortest distance path and the shortest time path.
Specifically, after the shortest distance path and the shortest time path in each direction of the passenger flow route of the station are determined, the shortest distance path and the shortest time path are displayed, and the shortest distance path and the shortest time path can be used as key management and control paths for passenger flow management and control, so that reference basis is provided for passenger flow management and control decisions.
For example, the shortest distance route and the shortest time route are separately displayed on the display screen, and each passenger control node through which the shortest distance route and the shortest time route pass is displayed, or all station passenger flow routes and corresponding passenger control nodes are displayed on the display screen, and the station passenger flow route corresponding to the shortest distance route and the shortest time route is indicated on the display screen (for example, by different color marks).
According to the method, the station passenger flow routes in the entering, exiting and transferring directions are determined by the passenger control nodes in the subway station, the shortest distance route and the shortest time route are determined and displayed based on the station passenger flow routes and the route passing time on each station passenger flow route, subway workers can conveniently make more appropriate management and control measures by taking the shortest distance route and the shortest time route as references, and the management and control effect is improved.

The subway station passenger flow line management and control method is embodied for the subway station passenger flow line management and control method. Referring to fig. 2, the method for managing and controlling passenger flow in a subway station includes:
s201: and acquiring the passing states of the station-entering node, the station-exiting node and/or the transfer node in the subway station in real time.
Illustratively, the inbound node, the outbound node and the transfer node are guest control nodes in the subway station, that is, nodes for controlling passenger flow, and correspond to guest control nodes through which an inbound route, an outbound route and a transfer route pass in the subway station, respectively. The passenger control nodes include but are not limited to entrances and exits, passageway (staircase, stair, elevator) going upstairs and downstairs, security check machine, gate, transfer passageway, platform, etc. It can be understood that different subway stations can arrange the types and the number of the corresponding passenger control nodes according to actual needs. The transfer passage is used for transferring different subway lines in the same subway station and can also be used for transferring the same subway line in different directions. The station entering node, the station exiting node and the transfer node can be determined by specific setting positions, types and numbers in the subway station, and are input into the subway station passenger flow line management and control device in a manual input mode or a mode of adding nodes on a subway station map.
Further, the passenger control nodes passed by the inbound route, the outbound route and the transfer route in the subway station are respectively defined as the inbound node, the outbound node and the transfer node. For a subway station, there will be an inbound route and an outbound route in the inbound and outbound directions, the transfer route in the transfer direction generally exists in a subway station where different railway lines converge, and this embodiment is described by taking as an example that the subway station simultaneously has the inbound route, the outbound route and the transfer route.
Fig. 3 is a schematic diagram of an entry node on a subway entry route provided in an embodiment of the present application, as shown in fig. 3, the entry route needs to enter a subway station from outside of the station through an entrance 1, sequentially passes through a station hall layer and a station platform layer, and finally arrives at a station platform to wait for a train to arrive, a security inspection machine 1-2 and a gate machine 1-4 are arranged in the station hall layer, and the entrance 1 and the station hall layer, and the station hall layer and the station platform layer are connected through a staircase 1-2 and a staircase 1-2, and the entrance, the staircase, the security inspection machine, the gate machine and the station platform in fig. 3 are all entry nodes on the entry route.
S202: a plurality of station passenger flow routes in the inbound, outbound and/or transfer directions are determined based on the traffic states of the inbound nodes, outbound nodes and/or transfer nodes within the subway station.
Illustratively, the passenger control nodes passed by the inbound route, the outbound route and the transfer route in the subway station are respectively defined as the inbound node, the outbound node and the transfer node. After the passenger control nodes in the subway station are determined, a plurality of station passenger flow routes in the inbound, outbound and transfer directions are determined based on the inbound nodes, the outbound nodes and the transfer nodes in the subway station.
Specifically, in the station entering direction, a plurality of station passenger flow routes in the station entering direction are determined by taking an entrance and an exit and a platform as a starting point and an end point and by the combination of different station entering nodes; in the outbound direction, taking the platform and the entrance and exit as a starting point and an end point, and determining a plurality of station passenger flow routes in the outbound direction by the combination of different outbound nodes; in the transfer direction, a plurality of station passenger flow routes in the transfer direction are determined with the platforms of different railway lines as the starting point and the ending point, and with the combination of different transfer nodes. Further, after determining different station passenger flow routes, the station passenger flow routes can be stored in a passenger flow route list for storage.
Furthermore, the passing states of the station-entering node, the station-exiting node and the transfer node in the subway station are monitored in real time, the passing state of the station passenger flow route is updated in real time according to the passing state of each passenger control node, and the station passenger flow route in the passing state is determined. For example, after the passenger flow management and control needs to restrict the passage of a certain passenger control node, all station passenger flow routes passing through the passenger control node are marked as a non-passage state, or one of the nodes is restricted as a one-way passage, and all station passenger flow routes passing through the passenger control node from the restricted direction are marked as a non-passage state. The passing state of the passenger control node can be determined according to the passenger control operation state of the subway station, and the passing state mark corresponding to the passenger control node is changed in a manual input or switching mode, wherein the passing state mark is used for marking the passing state of the passenger control node.

Fig. 5 is a schematic diagram of a passenger flow path of a station in an outbound direction according to an embodiment of the present application, as shown in fig. 5, where a platform layer arrives at a station hall layer through a node of an escalator 4 or a stair 4, and then arrives at an outbound node through a node of a gate 5, a gate 6, or a gate 7, and the outbound node includes an escalator 3 and a stair 3, and an entrance and an exit can be reached through the escalator 3 or the stair 3, it can be understood that security inspection is not required in the outbound direction.

The station passenger flow routes in the transfer direction can be arranged and combined according to each node, and each passenger flow route is in bidirectional traffic.
S203: and acquiring the passing distance between adjacent passenger control nodes of the station passenger flow route in the station entering, station exiting and/or transfer directions.
The passing distance between the adjacent passenger control nodes is the moving distance between two passenger control nodes which are adjacent in front and back and pass by the movement along the inbound, outbound or transfer direction. Specifically, after a plurality of station passenger flow routes in the entering, exiting and transfer directions in the subway station are determined, the passing distance between every two adjacent passenger control nodes passing from the starting point to the ending point of each station passenger flow route is calculated.
The passing distance can be obtained by measuring the moving distance between the passenger control nodes adjacent to each station passenger flow route in the corresponding direction on site through a measuring instrument, and can also be obtained by calculating the moving distance between the passenger control nodes adjacent to each station passenger flow route in the corresponding direction through a design drawing, and the corresponding passing distance can be obtained by moving the handheld mobile equipment between the passenger control nodes adjacent to each station passenger flow route in the corresponding direction by utilizing the distance measuring function of mobile equipment such as a mobile phone and a tablet.

In this embodiment, the shortest distance route includes an inbound shortest distance route, an outbound shortest distance route, and a transfer shortest distance route that correspond to the inbound, outbound, and transfer directions, respectively. After the passing distance between the adjacent passenger control nodes of each station passenger flow route is determined, the moving distance of each station passenger flow route is determined according to the sum of the passing distances between the passenger control nodes passed by each station passenger flow route, and the station passenger flow route with the minimum moving distance in the entering, exiting and transfer directions is used as the shortest entering distance route, the shortest exiting distance route and the shortest transfer distance route.
Taking the determination of the shortest route to the station as an example, with reference to fig. 4, there are 32 passenger traffic routes in the station entering direction, and it is assumed that the passing distance from the entrance 1 to the escalator 1 is L1F1The passing distance from the escalator 1 to the security inspection machine 1 is LF1A1The passing distance from the security inspection machine 1 to the gate 1 is LA1Z1The passing distance from the gate 1 to the escalator 2 is LZ1F2The passing distance from the escalator 2 to the platform is LF2ZTThen the moving distance of the inbound route is L11＝L1F1+LF1A1+LA1Z1+LZ1F2+LF2ZTWherein L is11And representing the moving distance corresponding to the first inbound route with the entrance 1 as the starting point, and so on to obtain the moving distance of each inbound route in the inbound direction, and then taking the route with the minimum moving distance in each inbound route in the inbound direction as the shortest inbound distance route. Generally, for one subway station, there are shortest distance paths in the inbound and outbound directions, and the shortest distance path in the transfer direction generally exists in subway stations where different railway lines converge.
In other feasible embodiments, the shortest distance path may be determined by sequentially selecting the smallest passing distances according to the directions corresponding to the station passenger flow route for accumulation after calculating the passing distances between adjacent passenger control nodes in each direction, and obtaining the shortest distance path in the direction according to the passenger control nodes corresponding to the accumulated passing distances.

S206: and determining the internode passage time between adjacent passenger control nodes in the station passenger flow route in the entering, exiting and/or transfer directions according to the time stamp.
Illustratively, after time stamps corresponding to all the passenger control nodes on the passenger flow path line of the station of a plurality of passengers in the inbound, outbound and transfer directions are acquired, the internode transit time of the adjacent passenger control nodes is determined according to the average time difference of the time stamps between the adjacent passenger control nodes in the corresponding directions. The term "internode passage time" is understood to mean the average time a plurality of passengers take to pass from the last passenger node to the next passenger node in the direction of arrival, departure or transfer. Generally, the longer the passing distance between adjacent passenger control nodes, the more the number of passing people, the tighter the control measures are, and the longer the corresponding internode passing time is. Specifically, the internode passage time includes steps S2061 to S2062:
s2061: and determining the time difference of adjacent passenger control nodes of a plurality of passengers in the entering, exiting and/or transferring directions of the passenger flow route passing through the station according to the time stamps.
The time difference between adjacent passenger nodes is understood to be the time it takes for a passenger to pass from the previous passenger node to the next passenger node in the direction of arrival, departure or transfer. Specifically, when the time difference between two adjacent passenger control nodes is determined, the time stamps of multiple passengers on the two passenger control nodes are obtained first, for each passenger, the time stamp corresponding to the next passenger control node in the corresponding direction is subtracted from the time stamp corresponding to the last passenger control node, the time difference that the passenger passes through the adjacent passenger control node is obtained, and the operation is repeated, so that the time difference that each passenger passes through the adjacent passenger control node is obtained. Further, the above operations are repeated to obtain the time difference corresponding to each adjacent passenger control node in the station passenger flow route in the station entering, exiting and transfer directions.
S2062: and calculating the average value of the time difference corresponding to each adjacent guest control node, and taking the average value of the time difference as the internode passing time between the corresponding adjacent guest control nodes.
Specifically, after time differences corresponding to each adjacent passenger control node in the entering, exiting and transfer directions of a plurality of passengers on the passenger flow route of the station are obtained, the average value of the time differences of the same adjacent passenger control node is calculated according to the time differences of each adjacent passenger control node, and the average value of the time differences is used as the internode passing time between the corresponding adjacent passenger control nodes.
For example, suppose that the passenger numbers P1/P2/P3 … Pn that a certain adjacent guest node can recognize (the face recognition device recognizes the face) and the time difference of P1/P2/P3 … Pn passing through the adjacent guest node is Tp1/Tp2/Tp3…TpnAnd then the internode transit time of the adjacent guest control node is as follows:
further, the timestamp for calculating the internode transit time may be all timestamps of the face recognition device at the corresponding guest node in a long time (such as a month or a quarter) so as to calculate the internode transit time in the long time, or may be a timestamp corresponding to the face recognition device at the corresponding guest node in a recent period of time (such as 10 minutes or an hour) so as to calculate the internode transit time in the short time, and the internode transit time of the corresponding time length may be selected according to the requirement of the passenger flow management and control analysis.
S207: and determining route passing time corresponding to a plurality of station passenger flow routes in the subway station entering, station exiting and/or transfer directions based on the internode passing time.
Wherein the route transit time is the time taken from the start point to the end point in the inbound, outbound or transfer direction. Illustratively, after the internode passage time between each adjacent passenger control node in the subway entrance, exit and transfer directions is obtained, the corresponding internode passage time on each station passenger flow line is summed according to the passenger control node passed by each station passenger flow line, and then the route passage time corresponding to each station passenger flow line can be obtained.
For example, taking the route passing time in the entering direction as an example, and taking the first entering route with the entrance 1 as the starting point as an example with reference to fig. 4, assume that the internode passing time from the entrance 1 to the escalator 1 is T1F1The time from the escalator 1 to the security inspection machine 1 is TF1A1The internode passage time from the security inspection machine 1 to the gate 1 is TA1Z1The section passing time from the gate 1 to the escalator 2 is TZ1F2The time of the passage between the escalator 2 and the platform is TF2ZTThen the route transit time of the inbound route is T11＝T1F1+TF1A1+TA1Z1+TZ1F2+TF2ZTWherein T is11Representing the route passing time corresponding to the first inbound route with the entrance 1 as the starting point, and so on, and obtaining the route passing time of each inbound route in the inbound direction. And similarly, the route passing time corresponding to the passenger flow route of each station in the outbound and transfer directions can be obtained. Generally, for a subwayThe station has the route passing time in the inbound and outbound directions, and the route passing time in the transfer direction generally exists in the subway station with different railway line collections.
S208: and respectively determining the shortest time route for entering, the shortest time route for exiting and/or the shortest time route for transfer of the station passenger flow route in the directions for entering, exiting and/or the direction for transfer based on the station passenger flow route and the route passage time.
Illustratively, after the route passing time of the station passenger flow route is determined, the route passing time corresponding to each determined station passenger flow route is compared, and the station passenger flow route with the shortest passage time among the corresponding routes is taken as the shortest time route. Generally, in a non-traffic control scenario, the shortest time path and the shortest distance path are the same station traffic route, while in a traffic control scenario, since individual traffic control nodes are restricted from passing, the shortest time path and the shortest distance path are different station traffic routes.
Specifically, the shortest time route includes an inbound shortest time route, an outbound shortest time route, and a transfer shortest time route, corresponding to the station passenger flow route in which the time taken to move from the start point to the end point in the inbound, outbound, and transfer directions is the shortest, respectively. After the route passing time of each station passenger flow route is determined, the route passing times in the entering direction, the exiting direction and the transfer direction are compared respectively, and the station passenger flow route with the minimum route passing time is used as the shortest entering time route, the shortest exiting time route and the shortest transfer time route respectively.
In other feasible embodiments, the determination of the shortest time path may be that after the internode transit time in each direction is calculated, the smallest internode transit time is sequentially selected according to the direction corresponding to the station passenger flow route for accumulation, and the shortest time path in the direction can be obtained according to the passenger control node corresponding to the accumulated internode transit time.
S209: and displaying a plurality of station passenger flow routes in the subway station entering, exiting and/or transferring directions.
Specifically, after a plurality of station passenger flow routes in the subway entrance, exit and/or transfer directions are determined, each passenger control node is displayed on a display screen, and a connecting line connecting the passenger control nodes through which each station passenger flow route passes is displayed, so that the station passenger flow routes are displayed.
S210: and displaying the shortest distance path and the shortest time path in the displayed station passenger flow routes.
Specifically, the shortest distance path and the shortest time path in the subway station entering, exiting and transfer directions are displayed on a display screen while the passenger flow route of the station is displayed. The shortest distance route and the shortest time route can be displayed independently, and the shortest distance route and the shortest time route can be displayed in different modes such as different colors, patterns, thicknesses and the like on the basis of the station passenger flow route, so that the shortest distance route and the shortest time route can be distinguished from other station passenger flow routes.

The total distance and the total time of different passenger flow streamlines can be obtained according to the distance or the time of adjacent nodes, and the path with the shortest distance and the shortest time is selected as a key path in the entrance and exit arrival direction through comparison.
For example, when a passenger flow management and control decision needs to be made according to a key management and control path, the shortest distance path is generally fixed and unchanged, passengers generally prefer the shortest distance path to move in a subway station, and when the passenger flow in the subway station is large or before a passenger flow peak occurs in the subway station, a current limiting device is additionally arranged on the shortest distance path or service personnel is added to guide the passenger flow, so that the situation of long-time congestion caused by excessive concentration of the passenger flow on the shortest distance path is relieved.
Aiming at the shortest time path, when the passenger flow in the subway station is normal, the shortest time path is generally overlapped with the shortest distance path, when the passenger flow in the subway station is large, part of passengers can select a proper fastest destination or a moving path with higher passenger flow speed according to the passenger flow of each path in the subway station, at the moment, the shortest time path can be changed along with different passenger flow scenes, and according to the shortest time path updated in real time, a current limiting device is additionally arranged on the shortest time path or service personnel is added for passenger flow guidance, so that the condition of long-time congestion caused by excessive concentration of the passenger flow on the shortest time path is relieved.
According to the method, the station passenger flow routes in the entering, exiting and transferring directions are determined by the passenger control nodes in the subway station, the shortest distance route and the shortest time route are determined and displayed based on the station passenger flow routes and the route passing time on each station passenger flow route, subway workers can conveniently make more appropriate management and control measures by taking the shortest distance route and the shortest time route as references, and the management and control effect is improved. And the time stamp of the passenger arriving at the passenger control node is obtained through the face recognition technology, the shortest time path is accurately calculated, and an important reference basis is provided for real-time monitoring of the passenger flow situation.
In other possible embodiments, the shortest time path at different time periods may also be determined based on the station passenger flow route and the route transit times at different time periods. For example, the timestamps acquired at each guest control node in different time periods (such as time periods 06: 00-07: 00, 11: 00-14: 00, 17: 00-18: 00 and the like) are saved, and the shortest time paths in different time periods are respectively saved. When the shortest time paths corresponding to different time periods need to be checked, the shortest time paths of the time periods can be displayed on the display screen in response to a shortest path checking instruction sent by an operator, the shortest time paths of the different time periods can be conveniently analyzed, and reference basis is provided for subway passenger flow management and control measures. Furthermore, the timestamps used for determining the shortest time path in different time periods can be screened, for example, only the timestamp of the last month or the timestamp of the last three months is selected, so that the obtained shortest time path is ensured to be closer to the actual situation.
