Embodiment Construction

[0043] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0044] A common infrared sensor layout for a pass gate is as follows: figure 1 shown.

[0045] For example, the entrance zone Zone1 of a common access gate is equipped with two infrared sensors S1 and S2 in the direction of entering the station. In this area, the entry authority of passengers is mainly checked. You can choose to configure authorization methods, such as credit card authorization and face authorization. After the authorization is successful, the system prompts permission to enter, and the swing door opens in the direction of entering the station. Passengers should perform authorized operations before entering this area. If they are not authorized, it is logically judged as an intrusion, and the audible an...

Abstract

The invention discloses a gate passing logic algorithm based on an LS-SVM classification algorithm, which is characterized in that passenger passing detection and a logic relation are researched, and a passing logic algorithm capable of automatically configuring sensors in a region is designed, so that the compatibility of the algorithm is stronger; a gate can enter a learning mode through a hardware or software method, when a passenger authorizes to pass through the gate, signal change of a passing sensor at this time is recorded, the signal change is converted into a sample sequence, and original data is preprocessed through a principal component analysis (PCA) method; data samples of a sensor are trained and classified through an LS-SVM model algorithm, normal passing samples are added into a credible list, abnormal passing is used as an alarm, a gate machine can be better suitable for various combined working conditions, the defect of incomplete functions or logic judgment defects caused by insufficient data samples after leaving a factory is effectively overcome, and the passing state of passengers in the channel can be identified more accurately.

Description

technical field [0001] The invention mainly relates to the field of security (involving a pass gate of an access control system), and relates to the application of sensors and data processing technology. Background technique [0002] The automatic ticket checking system is an automatic ticket checking system integrating computer, electronics, communication technology, automatic control and mechanical manufacturing. It is an important part of urban rail transit and has broad application prospects at home and abroad. Its core components are door blocking mechanism and pass logic algorithm. By analyzing the movement state of human body and other passing objects in the gate, it is identified and judged, so as to control the opening and closing of the gate mechanism. [0003] As a kind of automatic fare checking equipment in the subway automatic fare collection system, the use of gates has greatly improved the station's ability to handle large passenger flows. Under normal cir...
