Gate passing time prediction method and device

Abstract

The invention discloses a gate passage time prediction method and device. The method comprises the following steps: acquiring an infrared information sequence of pedestrians entering a gate at present; obtaining a preset pedestrian infrared sequence model; identifying a residual error between the infrared information sequence and the infrared prediction sequences corresponding to the different pedestrian types by using a residual error identification method, and judging whether the residual error exceeds a preset threshold value or not; if the residual error between the infrared information sequence and one of the infrared prediction sequences is lower than the preset threshold value, fusing the infrared information sequence and the infrared prediction sequence through an improved square root unscented Kalman filter algorithm to complete prediction of pedestrian passing time; and if the residual errors between the infrared information sequence and all the infrared prediction sequencesare all higher than the predetermined threshold, adopting a fuzzy control algorithm to complete prediction of pedestrian passing time. The passing efficiency of the gate can be improved.

Description

technical field [0001] The invention belongs to the technical field of public transportation coordination, and in particular relates to a method and device for predicting the transit time of a gate. Background technique [0002] The working process of the ticket gate generally includes the steps of swiping the card to check the ticket, opening the gate, passing pedestrians, and closing the gate. During the time interval from opening to closing of the gate, only one pedestrian should be allowed to pass; therefore, the opening time interval of the gate needs to be kept for a reasonable length of time. On the one hand, it is necessary to ensure that ticket inspectors can pass through calmly and safely, on the other hand, it is necessary to avoid trailing fare evasion behaviors caused by the gates being opened for too long. When the number of people passing through the gate exceeds the number of people who have checked the tickets, the buzzer will be activated to give an alarm,...

AI Technical Summary

Problems solved by technology

The behavior of breaking through the checkpoint not only causes fare evasion, but also brings a relatively high risk of accidental injury to the passer-by

[0003] The existing ticket gates mainly have the following defects in the passage logic control: First, the time interval from opening to closing after each ticket inspection is fixed, and in order to ensure safety and pass can be completed smoothly in most cases, this time The fixed duration of the interval can only be set to exceed the actual passage time of ordinary normal pedestrians. Although the exceeded duration is extremely short each time, it still has a non-negligible impact on the traffic efficiency. Sections or areas with dense passenger flow will reduce traffic efficiency

Secondly, for a small number of situations that cannot be completed within the above time interval, such as elderly people moving slowly, passengers carrying luggage and parents pulling children, etc., the turnstiles will open and close repeatedly in order to avoid accidental clamping, or there will be pedestrians If the gate is closed before passing through the blocker, this will reduce the traffic efficiency, and even need to be solved manually, resulting in the consequence that the gate cannot be effectively passed within a few minutes
