Based on the characteristics of large-scale personnel flow and difficult management, we have proposed an intelligent channel gate management solution. The system utilizes smart card technology, radio frequency electronic tag (RFID) technology, access control, and alarm output to realize the humanization and intelligence of the entrance and exit control, and solve the problem of community personnel access management.
The personnel entering and leaving the community can enter and exit through the card to realize the identity management of the personnel. The gate of the community door can select different gate passages such as three roller gates, wing gates and swing gates according to the actual characteristics of the community.
Residential channel gate advantages:
1. Enhance personal safety and strengthen property protection
2. Entrance and exit management can reduce security management costs
3. Effectively control the real-time records of incoming and outgoing personnel, and find problems in time.
4. Prevent potential hidden dangers and turn passive defense of other security systems into active control
5. Improve the grade of the community
The access control system of the community is generally installed in the entrance and exit gates, underground garage entrances and exits, unit doors, and equipment rooms. Most of them use RS485 communication methods, and some high-end villas also use TCP/IP communication.
Community channel gate function features:
1. Anti-tailing function: The infrared light band detection area in the channel can adjust the switch state by software according to the customer's precision requirements. The application of the light band to adapt to different requirements avoids the disadvantage that the point type infrared detector is easily contaminated and affects the reliability of judgment. Can effectively judge the followers of unread cards. When the system determines that a trailing occurs, the system will react based on the position of the valid cardholder returned by the infrared detector. After the door open signal is sent, there are still some abnormal use that will trigger the alarm system.
2. Abnormal use:
(1) The reverse intrusion when the door is opened After the door wing is opened, if an unauthorized pedestrian enters the door detection area in the reverse direction, the door is immediately closed, as long as the first protection detection belt detects the presence of someone, "aging" The function does not calculate the time at this time, and the door returns to normal operation when the person leaves the second detection zone.
(2) The trailing body detects the pedestrian from the first detector to the last detector that he left the first safety probe. The time gap is about 0.25 seconds. After the pedestrian leaves the first safety probe, the signal is in the reader. In the absence of an open door, the first detection zone detected a pedestrian (follower), the alarm sounded and the door remained open.
(3) When the pedestrian leaves the pedestrian, the pedestrian enters the second safety detection zone. Before the door returns to the basic state, the second safety detection zone detects that someone has entered without the legal door opening signal, and the alarm system issues an alarm. But as long as the protection detection area still detects someone, the door will not close.
