Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
With the rapid development of urban rail transit, the climax of subway construction is raised in various domestic big cities, and more people are willing to take a subway for going out. According to investigation, subway passengers tend to get on a certain number of doors close to an escalator, so that people in the area are crowded, meanwhile, people in other carriages are relatively rare, and finally, the passengers in the carriages of the subway are unevenly distributed. Particularly, when the flow of people is in a peak period, the situation of congestion is easy to occur, and even passengers get on the vehicle in time, so that the clamped injury accident is caused.
In order to effectively improve the situation, balance the congestion situation of the vehicles and the staff at the platform, improve the traffic efficiency and the transportation efficiency of the vehicles in the station, and reduce the cost of equipment installation, maintenance and the like generated by the early warning system, the scheme provides the early warning system and the method based on the passenger flow distribution of the train.
Referring to fig. 1, the early warning system based on train people flow distribution provided by the embodiment of the invention includes a camera 100 of a train PIS system, a vehicle control module 200 of a train TCMS system, and a man-machine interface module 300;
the camera 100 of the train PIS system is used for acquiring passenger information in each carriage of the train and sending the passenger information to the vehicle control module;
it should be noted that, each module in the early warning system provided by this scheme is a device carried by the train/platform itself, that is: the camera of the train PIS system, the vehicle control module of the train TCMS system and the man-machine interface module are all devices of the train/platform, so that corresponding hardware devices do not need to be added on the train/platform again when early warning operation is executed, hardware installation and maintenance cost is saved, and a large amount of labor is saved.
In this embodiment, the camera for collecting passenger Information is a camera of a train PIS system, and PIS (passenger Information system) is a passenger Information system, and the passenger Information in each carriage in the subway can be collected through the camera; it can be understood that this camera can be divided into two kinds, one kind is ordinary camera, the carriage picture in this ordinary camera can shoot the carriage, this carriage picture accessible analysis reachs the train flow of people distribution situation automatically, consequently, if this camera is ordinary camera, then the carriage picture that ordinary camera was shot is passenger information just, and send this passenger information to vehicle control module through communication module, so that this vehicle control module analysis this carriage picture, obtain corresponding warning information.
Furthermore, the camera of the train PIS system can also be a camera with a portrait recognition function. That is to say, in order to reduce the workload of the vehicle control module, each camera may be set as a camera which has an image recognition function, so that after the camera collects a picture of a carriage in a train carriage, a passenger of the picture of the carriage needs to be recognized, passenger information in the carriage is determined, and the passenger information is sent to the vehicle control module; and after the vehicle control module receives the passenger information of different carriages, the train personnel distribution condition, the reminding information and the shunting information can be directly generated according to the passenger information.
It should be noted that, if the camera is a camera with a portrait recognition function, the passenger information is information about the number of people in the vehicle or the degree of congestion of the vehicle, which has been processed by the camera, for example: the number of people in the carriage, the number of people at the door of the carriage, the number of people in the middle of the carriage, the distribution situation of people in the carriage, the crowdedness degree of the door of the carriage, the crowdedness degree of the middle of the carriage and the like. At this moment, after the vehicle control module receives the passenger information sent by the cameras in each carriage, the reminding information comprising the distribution condition of train personnel, the reminding information and the shunting information can be directly generated according to the passenger information of each carriage, and the workload of the vehicle control module is effectively reduced.
The vehicle control module 200 is configured to generate corresponding reminding information according to the passenger information, and send the reminding information to a human-computer interface module; the reminding information comprises: train personnel distribution condition, early warning information and shunting information;
it should be noted that the vehicle Control module in this scheme may be understood as a central processing unit ccu (communication Control unit), that is, a vehicle Control module vcm (vehicle Control module) in a Train TCMS (Train Control and Management System), and is mainly configured to receive passenger information sent by a camera, process the passenger information, generate reminder information, and send the reminder information to a human-computer interface module.
As can be seen from the above discussion, according to the difference in the types of the cameras, the vehicle control module generates corresponding reminding information according to the passenger information mainly includes two ways, one of which is: when the camera is a common camera, the passenger information is a carriage picture in the carriage, so that the vehicle control module needs to analyze the carriage picture to obtain the personnel distribution conditions of different carriages and generate corresponding early warning information and shunting information; the other one is as follows: the camera is the camera that has portrait recognition function, and the passenger information that this moment vehicle control module acquireed is the personnel distribution condition of different carriages promptly, alright at this moment directly according to the personnel distribution condition of different vehicles, generates early warning information and reposition of redundant personnel information.
It should be noted that, no matter the camera analyzes the car picture to obtain the distribution of the people in the vehicle, or the vehicle control module analyzes the car picture to obtain the distribution of the people in the vehicle, the distribution of the people reflected by the car picture can be analyzed by different image processing methods, in this embodiment, the image processing method is not limited, and different processing methods can be selected according to actual requirements; referring to fig. 2, a schematic diagram of an image processing flow proposed in the present scheme is shown; as can be seen from fig. 2, after the system is started, the acquired car picture is divided into a plurality of sub-regions, a background map corresponding to each sub-region is determined, background subtraction processing is performed on the background map of each sub-region, and after marginalization processing is performed on each sub-region, the total number of people in the car picture is obtained.
When the total number of people in the car picture is obtained, the number of people at different positions in the car picture can also be obtained, for example: the number of people at the door of the carriage and the number of people in the middle of the carriage; further, according to the total number of people, the number of people at the door of the carriage, the number of people in the middle of the carriage, and the degree of crowding of the carriage and different positions in the carriage can be determined according to a preset threshold value.
It can be understood that, after the personnel distribution situation of each car is determined, a train personnel distribution situation including the personnel distribution situation of each car can be generated, and through the train personnel distribution situation, the following can be reflected: the number of people in the current train compartment is large, the number of people in the current train compartment is small, the number of people in the current train compartment is large, and the number of people in the current train compartment is small. After the information is determined, the corresponding early warning information and the corresponding shunting information can be generated according to the preset early warning rule and the preset shunting rule.
It should be noted that, the scheme does not specifically limit how to determine the early warning information and the diversion information according to the distribution situation of train personnel, and may adaptively adjust according to the actual demand, in this embodiment, only the following situations are taken as examples for explanation:
if the early warning rule is: if the number of people with the carriages exceeds a preset threshold value, generating early warning information with more number of the carriages, wherein the early warning information can comprise all carriage numbers exceeding the preset threshold value; if the difference value between the number of people at the door of the carriage and the number of people in the middle of the carriage is larger than a preset threshold value, generating early warning information with uneven distribution of people in the carriage, wherein the early warning information comprises all carriage numbers with the phenomenon.
Correspondingly, the shunting rule corresponding to the early warning rule is as follows: if the number of people with the carriage exceeds a preset threshold value and the early warning information with more carriage number is generated, the generated shunting information can be as follows: reminding users to avoid getting in the carriage with a large number of passing persons as much as possible, and preferentially selecting the carriage with a small number of passing persons to get in the carriage, for example: the passengers are reminded of more passengers in the X1, X2 and X3 compartments, and the passengers are reminded of less passengers in the X4, X5 and X6 compartments, so that the passengers can get on the vehicles from the X4, X5 and X6 compartments preferentially; if the early warning information that the personnel distribution in the carriage is uneven is generated, the generated people flow information can be as follows: reminding users that the number of people at the door of the carriage is more, the number of people in the middle of the carriage is less, and suggesting that the passengers far away move to the middle of the carriage.
The human-machine interface module 300 is configured to display the reminding information.
In this embodiment, the human-computer interface module is mainly used to display the reminding information, and the manner of displaying the reminding information may be, but is not limited to: show through the display screen, show through sound, show to user terminal through initiative propelling movement, for example: the distribution condition, the early warning information and the shunting information of the train personnel can be displayed through a display screen arranged in the train or at a station; the distribution condition of train personnel, early warning information and shunting information can be played through a broadcasting system arranged in the train or at a station; similarly, still can initiatively with this train personnel distribution situation, early warning information and reposition of redundant personnel information propelling movement to user terminal, APP in the user's accessible terminal receives above-mentioned information to know train people flow distribution situation at any time, obtain early warning information and reposition of redundant personnel information, prepare in advance for oneself trip.
To sum up, this scheme mainly realizes early warning and reposition of redundant personnel flow to the subway through the camera of train PIS system, the vehicle control module and the man-machine interface module of train TCMS system, also promptly: the scheme fully utilizes the equipment of the train to realize the early warning and the shunting of the subway pedestrian flow distribution, can obviously improve the system reliability, and simultaneously saves a large amount of labor and equipment cost.

It should be noted that the early warning system in this embodiment further includes an event Recording module, where the event Recording module may be understood as a storage unit of the system, and in this embodiment, the event Recording module may adopt an erm (event Recording module) module in the train TCMS, and is mainly used for storing data, event Recording, fault Recording, and other functions; through this incident record module, can keep passenger information, train personnel distribution condition, early warning information and reposition of redundant personnel information in the train carriage to carry out data analysis in the future.
Further, referring to fig. 3, a schematic diagram of an overall structure of an early warning system according to an embodiment of the present invention is provided; the communication module in the scheme comprises a train Ethernet module and a train 4G communication module in the train TCMS, wherein the train Ethernet module is used for internal communication of each module of the train TCMS system and communication with other subsystems of the train, the bandwidth is high, the transmission speed is high, and the requirement of high-speed and high-capacity data transmission can be met. The train 4G communication module is used for communicating the train TCMS system with the station dispatching room broadcast video equipment, transmitting the personnel distribution condition, the early warning information and the shunt information in the train to the station, and guiding passengers on the station to take the train in order through platform broadcasting and television.
Based on any of the embodiments described above, in this embodiment, the vehicle control module is specifically configured to: processing the carriage picture of each carriage to obtain the distribution condition of train personnel; judging whether a carriage with the number of passengers larger than an overrun threshold exists according to the train personnel distribution condition; if so, judging whether a carriage with the number of passengers larger than a congestion threshold exists;
if the number of passengers in the carriage is larger than the congestion threshold, generating corresponding early warning information and shunting information, and sending the distribution condition of the train personnel, the early warning information and the shunting information to a human-computer interface module of the train and the station; and if the number of passengers in the train is not larger than the congestion threshold, generating corresponding early warning information and shunting information, and sending the distribution condition of the train personnel, the early warning information and the shunting information to a human-computer interface module of the station. Wherein the overrun threshold is less than the congestion threshold.
Fig. 4 is a schematic diagram of an early warning process based on train pedestrian flow distribution disclosed in this embodiment; as can be seen from the figure, after the train is started and self-checked, if no problem exists, the picture of the carriage is shot through the camera and uploaded to the vehicle control module; the vehicle control module processes the carriage picture, outputs the distribution condition of train personnel, and for the number R of people in a certain area, if R is not more than or equal to the overrun threshold value and the operation is finished, the flow is finished, otherwise, the picture shot by the camera is continuously analyzed; if R is larger than or equal to the overrun threshold, judging whether R is larger than or equal to the congestion threshold, if so, distributing the people flow early warning information, and synchronously guiding and shunting at the carriage station; if not, the pedestrian flow early warning information is distributed, and after early warning, the flow distribution is guided only at the station. Wherein the number of people exceeding the threshold is less than the number of people crowding the threshold.
In this flow, the number of people in a certain area is the number of people in different cars, and after the number of people in each car is determined, it is known which car has a large number of people and which car has a small number of people.
It should be noted that the human-machine interface module can be divided into two types according to the display position: one is positioned on the train and is used for displaying reminding information on the train; the other is positioned at a station, and reminding information is displayed in the station; if the human-machine interface module is located on the train, the human-machine interface module comprises: a train PIS system or a train PA system; the train PIS system is used for displaying reminding information on a display inside a carriage; and the train PA system is used for playing the reminding information in a broadcasting mode in the carriage. That is, if the prompt information is displayed on the train, the distribution condition of personnel in the train, the early warning information and the shunting information can be displayed through a display in the train PIS system; the prompt information can also be played in a broadcast mode through a broadcast control unit PA on the train.
It should be noted that the system further includes: and the train power supply module is specifically used for supplying power to a train PIS system, a train TCMS system and a train PA system. Specifically, the TCMS, PIS and PA systems are all powered by a train storage battery DC 110V.
