Problems solved by technology

[0005] For this reason, the technical problem to be solved by the present invention is that the way of counting the number of passengers at the station is extensive, it is impossible to accurately calculate the passenger flow and count the real-time passenger number in the station, and there is no flow limiting measure, so a method based on multi-point passenger flow detection information feedback is proposed Station automatic current limiting method

Embodiment 1

[0044] This embodiment provides a station current limiting method based on multi-point passenger flow detection information feedback, the flow chart of which is as follows figure 1 shown, including steps:

[0045] 1. The passenger flow of each channel is captured in real time by the deep HD camera, and the number of passengers in the station hall and platform is detected and calculated in real time through the head detection and recognition technology, and the increase trend of the number of passengers on the platform is analyzed.

[0046] 2. Calculate the remaining amount of passengers that can be accommodated in the station hall according to the number of passengers in the station hall. The remaining amount of passengers that can be accommodated in the station hall is the number of passengers accommodated in the station hall minus the existing number of passengers in the station hall; Calculate the remaining amount of passengers that can be accommodated by the platform, and ...

Embodiment 2

[0050] This embodiment provides a station current limiting method based on multi-point passenger flow detection information feedback, its flow chart can be found in figure 1 shown, including steps:

[0051] First, the passenger flow of each channel is captured in real time through the deep HD camera, and the number of passengers in the station hall and platform is detected and calculated in real time through the head detection and recognition technology, and the increase trend of the platform passenger volume is analyzed. The method for the real-time detection calculation is: obtain the head shape and texture features of each pedestrian according to the pre-selected video data, and then establish the pedestrian head model according to the head shape and head texture features of each person. According to the pedestrian head model, obtain the pedestrian head information in the detection area in each frame image; create a queue for each pedestrian head information in the first fr...

Embodiment 3

[0080] This embodiment provides a station automatic current limiting method based on multi-point passenger flow information feedback and is applied to subway current limiting. The specific steps are:

[0081] First, calculate the number of passengers in the station hall, the calculation method is as follows:

[0082] S zt ( t + Δt ) = S zt ( t ) + Σ i = 1 m q zt , i in ( Δt ) - Σ i = 1 n q zt ...

Abstract

The invention provides a station automatic flow limiting method based on multipoint passenger flow information feedback.It comprises the steps that the number of passengers in a station hall and the number of passengers at a platform are detected and calculated in real time, and in addition, the number increase trend of the passengers at the platform is analyzed; the rest quantity of passengers capable of being contained in the station hall and the rest quantity of passengers capable of being accommodated at the platform are calculated; the number of passengers going into or out of the station hall is regulated in real time according to the rest quantity of passengers capable of being contained in the station hall; the number of passengers going into or out of the platform is regulated according to the rest quantity of passengers capable of being accommodated at the platform; the number increase of the passengers in the station hall caused by the passengers going into or out of the platform is regulated according to the number of the passengers going into or out of the platform, and the number of the passengers going into or out of the station hall is further regulated for reaching the flow limiting goal. The station automatic flow limiting method has the technical scheme that the numbers of the passengers of the platform and the station hall are detected and calculated in real time, the number of the passengers at the platform is subjected to flow limitation through the increase trend of the number of the passengers at the platform, meanwhile, when the practically detected number of the passengers exceeds the number of the passengers capable of being accommodated at the platform, the flow limitation is carried out in real time through further regulating the number of the passengers going into the platform and the station hall, the algorithm is precise, the flow limiting modes are comprehensive, the timeliness is high, and safety and reliability are realized.

Description

technical field [0001] The invention relates to a station automatic current limiting method based on multi-point passenger flow detection information feedback. The invention belongs to the technical field of traffic management automatic control. Background technique [0002] Station flow restriction is a short-term countermeasure adopted by station operators to avoid excessive pressure on lines or road networks caused by large passenger flows. Its main purpose is to reduce transportation pressure and accident risks by controlling passenger flow distribution, thereby ensuring station safety. The main means of limiting traffic at stations include closing ticket vending machines, gates, setting up railings, closing entrances and exits, closing transfer channels, closing stations, etc. The main application occasions are: (1) limit the passenger flow per unit time during peak hours, and reduce the congestion of stations or lines; (2) slow down or limit the passenger flow when st...
