Referring to fig. 1, an embodiment of the present invention provides a subway security check queuing guidance method, including:
step S100, a plurality of cameras are arranged in each security inspection opening area of the subway so as to cover the whole pedestrian flow area of each security inspection opening.
Generally, for guaranteeing the security, the subway needs to carry out the machine inspection to the parcel that each passenger carried, and the parcel is placed and is carried out the machine inspection and need be for a certain time at the track, consequently under the more condition of traffic of people, the security installations mouth leads to the fact the condition of lining up or even blocking up easily, and subway managers is limited, and the organization management population dynamics is limited, consequently takes place easily that population too gathers and causes the incident such as trample, very insecure.
Thus, several cameras are arranged at each security checkpoint for detecting the flow of people. The existing advanced cameras have the function of image recognition and analysis, and the cameras can directly report the number of people in the current monitoring area to a background.
And step S200, the background server acquires the pedestrian volume data of each security inspection opening area uploaded by the camera.
Specifically, the uploaded background network address is set for the camera. The camera is provided with a hardware operating platform which can be configured by technicians, and the technicians can set the network address uploaded by the background through the hardware operating platform, so that the camera can upload the identified people flow to the background server through the set uploading frequency. Exemplary are as follows:
Set upload address”106.12.10.1”
the above is an exemplary setting, "106.12.10.1" is a backend server network address, and when the configuration is written into the camera, the camera will upload the identified traffic to the backend server network address, and in addition, the uploading frequency of the camera can also be set in the hardware operating platform.
And step S300, the background server calculates according to the people flow data to generate index parameters for representing people flow density.
Specifically, after receiving the people flow data uploaded by the camera, the background server calculates index parameters for representing the people flow density according to a preset training model and the uploaded people flow data. Therefore, calculation is performed, and real-time data conversion is performed, if people flow data is directly displayed to passengers at an entrance, the passengers do not actually know that the people flow means crowding or few people, and the sizes of all stations are inconsistent, so that data conversion calculation is required to be performed, and the data is converted into index parameters which are easily and quickly understood by the passengers.
Illustratively, a certain subway station has 4 station ports, which are respectively an a port, a B port, a C port and a D port, wherein at the time of 5 o' clock, the comprehensive data reported by each camera is 35 persons at the a port, 3 persons at the B port, 6 persons at the C port and 26 persons at the D port, so that the data form an array or a matrix, the array or the matrix is transmitted to a stored training model, and the waiting time of the a port is calculated to be 18 seconds, the waiting time of the B port is calculated to be 3 seconds, the waiting time of the C port is calculated to be 5 seconds, and the waiting time of the D port is calculated to be 15 seconds.
And S400, the background server generates a display control message according to the index parameters, and sends the display control message to a screen for displaying, wherein the screen is arranged at an outlet of each safety inspection port of the subway.
Specifically, after the index parameter is generated, the background server generates a display control message according to the index parameter, wherein the display control message can be sent to a display screen erected at an exit (i.e. an entrance) of each security inspection port of the subway for display by the index parameter and/or an image corresponding to the index parameter.
In addition, the display screen is most preferably arranged at each exit of the subway, so that passengers can know the queuing condition of each security inspection port before entering the station, and the phenomenon that the security inspection ports cannot be changed because no line-changing channel without security inspection exists in part of stations is avoided.
The invention provides a subway security check queuing guidance method, which is characterized in that the passenger flow in the security check area of each subway station is counted by a passenger flow camera, and data is reported to a background service center at regular time; through the calculation of the background, the number of people queuing at each safety inspection port, the approximate queuing time and the number of people staying in the station are transmitted to the subway port screen for displaying in real time so as to be used for the decision-making planning of the outgoing of the passengers coming into the station, and the problem of over-congestion of part of the safety inspection ports is solved.
Optionally, the people flow data includes a number of monitored areas.
Specifically, the traffic data may be the total population of the monitored area, which is as follows:
and D is 35, wherein D is the ID of the D port of the security inspection port.
Optionally, the index parameters of the people stream density include queuing time and the number of people in the queue.
Optionally, in step S300, the step of calculating, by the background server according to the people flow data, and generating an index parameter for representing the people flow density includes:
in step S310, the background server sets a plurality of variables, each of which represents each security checkpoint area.
Specifically, the background server is provided with a plurality of variables which are respectively used for representing each security inspection opening area, because the number of the cameras in a partial area is more than one, the variables need to be set and the number of the cameras is superposed,
illustratively, a variable X is provided to represent the number of people in the security inspection portal a, and the security inspection portal a is provided with two cameras 001 and 002, the number of people reported by the camera 001 is 35, the number of people reported by the camera 002 is 22, so that X is 35+22, and the output value of X is 57.
In addition, it should be noted that the monitoring areas of the cameras set by the single security inspection ports cannot be overlapped.
Step S320, according to the received people flow data of each security inspection opening, the people flow of each security inspection opening is calculated through a preset training model, and therefore the queuing time and the queuing number of people corresponding to each security inspection opening are obtained.
Specifically, the background server is provided with a training model for calculating the people flow data of the security inspection opening, exemplarily continues the exemplary scenario set forth in S310 to obtain X, that is, 57 people at the security inspection opening a, and calculates through the training model to obtain the queuing time and the queuing number, and the specific training model will be set forth below.
And step S330, assigning the queuing time length and the number of the queuing people to corresponding variables.
After the calculation is completed, the calculation result is assigned to corresponding variables, such as a queuing time variable X1 of a security inspection port A and a queuing number X2.
Optionally, the training model includes a relationship between the flow rate of people in each cycle time and the queuing time and the number of people in the queue.
Optionally, in step S400, the step of generating, by the background server, the display control message according to the index parameter includes:
and S410, converting the number of the people in the queue into text data by the background server, and pulling the corresponding chartlet according to the number of the people in the queue to generate image data.
Step S420 encapsulates the text data and the image data to generate a display control message.
Illustratively, if the generated queuing time is 15 seconds and the number of people in the queue is 30, converting the queuing time of 15 seconds into a notepad text, and pulling corresponding chartlet data according to the number of people in the queue of 30 to form a jpg-format image, wherein the relationship table of the number of people in the queue corresponding to the chartlets is exemplarily as follows:
| number of people | Number of pictures stuck | Paste color |
| 0-10 | 1 | Green |
| 10-30 | 2 | Yellow colour |
| More than 30 | 3 | Red wine |
As shown in the table above, the number of people in the queue is 30, the people belong to the second section, two pasters are copied, one yellow layer is covered on each of the two pasters, the final file is stored to form a jpg format image, the format image and the note book text are sent to a display screen to be displayed, and the setting of the format can enable a low-configuration or low-intelligence screen to be identified as well.
Optionally, the step of pulling the corresponding map to generate the image data according to the number of people in the queue includes:
accessing a variable numerical value of the number of queuing people, and judging the interval to which the numerical value belongs;
and selecting one of three preset human body maps of red, yellow and green according to the interval, wherein the red color is used for representing too many people, the yellow color is used for representing moderate people, and the green color is used for representing less people.
Optionally, the step of calculating, by the background server, according to the people flow data to generate an index parameter for representing the people flow density includes:
wherein r is the number of people in the queue, x is the passing rate of the security inspection, y is the queuing time, and c is the time of the emergency.
Specifically, the pre-stored training model described in the foregoing is a function, y, x, and r are constants, and c is a variable, and often, it is often predicted that some people struggle with case personnel in the subway, or there are prohibited articles in the package, which leads to events such as security inspection stagnation, which occur with a high frequency during spring transportation or a holiday, so that the duration of the emergency is added to the model as a variable, and the historical data is used to train c, for example, the number of the emergency in 5 months is only 1, the probability is very low, so the value assigned to c is 0.15, while the number of the emergency in national celebration in 10 months is 30, the frequency is very high, and therefore the assignment to c needs to be increased to 3 seconds.
Referring to fig. 2, the present invention further provides a queuing guidance apparatus, including:
the image module is used for arranging a plurality of cameras for each security inspection opening area of the subway so as to cover the whole pedestrian flow area of each security inspection opening;
the acquisition module is used for acquiring people flow data of each security check area uploaded by the camera by the background server;
