Application of subway gate in daily life of passage gate
In recent years, China’s urbanization has developed rapidly, and the increase in urban migrant workers has brought huge transportation pressure, so subway rail transit has emerged. We know that there will be no traffic jams when taking the subway, and the speed is fast. Compared with traveling by bus or self-driving, it is very convenient in the environment of heavy traffic in the city. Then the subway gate system is responsible for the toll and release by the subway. The subway gate system solution perfectly solves the problem of people taking the subway tolls, improves the efficiency of passage, and shortens the transit time. When the pedestrian walks to the gate You only need to insert a coin, swipe a card, or scan a QR code to authorize and the gate will automatically open to pass, and the system will automatically complete the charge. So how does the subway gate system work? The editor of Chuangxintong will give you a brief analysis.
In the subway gate system, the wing gate is a common one, which is linked by multiple channel wing gates. The middle gate is equipped with a dual movement to control the front and back movement of the wing arms on both sides. The gates on both sides Install a stand-alone machine, and realize the obstruction and release of pedestrians through sensor technology and motor control technology. The sensor generally installed in the subway gate system is a through-beam photoelectric sensor, which is more accurate for sensing the human body. In order to realize the in and out sensing of passers-by, generally a subway gate will use multiple sets of beam sensors. It can be understood as consisting of three parts, gate entrance, wing arm position, gate exit. To achieve precise sensing, sensors can be installed at different heights of the gate. There are many ways to pass through the gates, such as coin insertion, swiping cards, scanning QR codes, and some gates even have a face recognition system installed. Let's make an introduction by swiping the card.
When a pedestrian approaches the gate and swipes the card, the card will beep on the sensor window at this time, and the control system will get the gate opening signal, and the gate will be opened. The ticketing and billing system is also integrated in the subway gate. Record the time and location of the passenger's first swiping card, that is, entering the station, and the time and location of the passenger's second swiping card, that is, exiting the station, and then calculate the fare and automatically deduct it from the card. When there are many passengers entering and exiting the station and need to line up to swipe their cards to enter and exit, the induction system will shield multiple people from swiping cards near the gates, that is to say, only one person is allowed to enter the gate sensing area at a time to swipe their cards to enter the station, and others should stand outside the yellow ground line and wait , Otherwise the swiping card will be invalid. This will automatically clear the order of people entering and leaving the station, and urge everyone to stand outside the yellow line and wait in line to enter and leave the station.
