Qingdao Road gate installation - what is the difference between intelligent access gate and license plate recognition road gate

What's the difference between a gateway and a gateway? Although the passage gate and the passage gate belong to the entrance and exit control equipment, there are still some differences. The access gate is mainly used in places with large flow of people to control the flow of people. The access gate is mainly used in the parking lot to control the entry and exit of vehicles. The following small series will focus on popularizing the knowledge of channel gates for everyone!



The access gate is one of the common devices in the access control system. The access gate is actually the management of people. The channel gate covers three roller gate, wing gate, swing gate, barrier free channel system, etc. In different entrance and exit scenarios, different types of channel equipment are required. For example, the three roller gate and rotary gate of the venue, and the pedestrian passage of campus, enterprises and high-end intelligent buildings.



Three roller gates are widely used for simple dissuasion level access control in public channels. It is widely used in factory attendance system, public institution consumption system, community access control management, ticket inspection system of venues such as scenic spots, palm system management of construction sites, etc. With a variety of different configurations, it can be applicable to all building environments and solve all control problems of pedestrian access. Different identification systems can be configured (ID card, IC card, bar code, palm shape, fingerprint, iris, etc.).



With its beautiful and generous appearance, wing gate is often used in government units because it brings a sense of seriousness. Swing gate can be divided into two types, one is general swing gate (i.e. front and rear swing gate), and the other is lower swing gate.



Compared with the wide and solid feeling of the wing gate, the swing gate is concise and generous. The general swing gate can be used as both double swing and single speed gate independently.

The lower swing gate is often used in senior office buildings, government departments or airports.



The barrier free access gate is not equipped with a gate rod, and the passing personnel are checked by infrared induction method to achieve the purpose of barrier free card swiping or direct calculation of pedestrian flow. The passage gate equipment can ensure 35 people to pass in one minute, which is suitable for occasions with high requirements for traffic efficiency and overall beauty.



General functional characteristics of access gate



1. Anti tailing function: there is an infrared light band detection area in the channel. The switch state can be adjusted by software according to the accuracy requirements of customers to adapt to the application of light bands with different needs, so as to avoid the shortcomings that the point infrared detector is easy to be polluted and affect the judgment reliability, and can effectively judge the followers who have not read the card. When the system determines that the following occurs, the system will react according to the position of the valid cardholder returned by the infrared detector. After the door opening signal is sent, there are still some abnormal uses that will trigger the alarm system.



2. Abnormal use:



(1) When the door is opened, reverse intrusion. After the door wing is opened, if an unauthorized pedestrian enters the door detection area in the reverse direction, the door will be closed immediately. As long as the first protective detection belt detects the presence of someone, the "time effect" function will not calculate the time at this time. When the person leaves the second detection area, the door will resume normal operation.



(2) When the door is closed, the reverse intruder enters the door body after the authorized door opening signal is sent. Before passing the first safety photoelectric detection belt, if the reverse detection belt detects someone entering, as long as the person does not leave, the buzzer will always give an alarm and the door remains closed. The "time effect" function does not calculate the time interval at this time.
