A gate passage recognition method based on infrared detection key points

Abstract

The invention discloses a gate passing recognizing method based on infrared detecting key points. The method comprises the following steps: firstly, arranging a gate infrared sensor, and mounting a corresponding infrared detecting light curtain board; dividing a gate channel into four areas including an entrance area, a passing area, a safe area and an exit area sequentially, in the entrance direction; then setting the gate passing modes including five working modes, namely, a normal-opening mode, a normal-closing mode, an emergency mode, a repair mode and an open mode; if the working mode is set as the normal-closing mode and the gate is in a normal working state, allowing setting of nine passing modes, namely, a two-way control mode, an incoming-direction controlling and outgoing-direction locking mode, an incoming direction controlling and outgoing direction freeing mode, an incoming direction locking and outgoing direction freeing mode, a two-direction locking mode, an incoming direction locking and outgoing direction freeing mode, an incoming direction freeing and outgoing direction controlling mode, an incoming direction freeing and outgoing direction locking mode and a two-direction freeing mode; and finally selecting five key points for state detection, and recognizing the gate passing by adoptingthe state tracking method. The method is simple, convenient and reliable, and can effectively recognizeand avoid the behavior of people following up to sneak through without a ticket.

Description

Technical field [0001] The invention belongs to the technical field of passage gate systems, and particularly relates to a gate passage recognition method based on infrared detection key points. Background technique [0002] With the development of my country's economy and the continuous increase of urban population density, there is an urgent need for an automatic fare collection system to relieve the pressure on the flow of people. The gate is one of the most critical equipment in the rail transit automatic ticketing and ticketing system. However, the current automatic ticket checking technology in my country is not mature enough. The domestic high-speed rail and subway ticket checking systems mostly use foreign equipment or components, such as Margarita from Germany, Gulibao from Sweden, and ACE from Japan. In recent years, the demand for gate equipment in the Chinese market has increased. Many domestic enterprises and research institutions have conducted a lot of research wor...

Problems solved by technology

However, at present, my country's automatic ticket checking technology is not mature enough. Domestic high-speed rail and subway ticket checking systems mostly use foreign equipment or components, such as Margaret in Germany, Gulibao in Sweden, ACE in Japan, etc.

In recent years, the demand for gate equipment in the Chinese market has been increasing. Many domestic enterprises and research institutions have conducted a lot of research work on gate technology, and the technical level is also constantly improving. However, key components and core technologies still exist. There is a large gap, and the overall technical level of turnstiles still needs to be improved

[0003] The existing gate access system cannot select a specific number of infrared light curtain panels, and the optional access scheme is relatively single, which is difficult to meet the demand for gate equipment in the Chinese market

At the same time, in the existing scheme, only the method of area recognition is used, and the recognition effect is poor
