company news about What are the features of the speed gate？

1. Anti-trailing function: There is a common infrared light band detection area in the channel, and the switch state can be adjusted by software according to the customer's precision requirements, and the application of light bands to meet different needs avoids the shortcomings of point infrared detectors that are easily polluted and affect the reliability of judgment. It can effectively determine the trailing person of the unread card. When the system determines that tailgating occurs, the system will respond according to the position of the valid cardholder returned by the infrared detector. After the door open signal is issued, there are still some abnormal use will trigger an alarm.

2. Abnormal usage:

(1) When the door is closed, a pedestrian who enters in the opposite direction walks into the door after the authorized door opening signal is issued. Before passing the first safety photoelectric detection belt, if the reverse detection belt detects that someone has entered, as long as the person does not leave, the buzzer will sound. The alarm will always sound and the door will remain closed, the "Aging" function does not count the time interval at this time.

(2) Reverse intrusion when the door is opened After the door wing is opened, if there is an unauthorized pedestrian entering the door body detection area in the reverse direction, the door will be closed immediately, as long as the first protection detection belt detects the presence of someone, "time limit" The function does not count the time at this time, and the door resumes normal operation when the person leaves the second detection zone.

(3) Pedestrians enter in the opposite direction when they leave. The pedestrian passes through the second safety detection area. Before the door returns to the basic state, the second safety detection area detects that someone has entered without a legal door opening signal, and the alarm system issues an alarm. But as long as the protection detection zone still detects someone, the door will not close.

(4) Following closely from the first detector to the last detector when he left the first safety detection zone, the time gap is about 0.25 seconds. After the pedestrian leaves the first safety detection zone, the card reader signal In the case of no door opening, the first detection zone detected a pedestrian (trailer) again, the alarm sounded long, and the door was still open.

(5) After the normal trailing pedestrian leaves the protection detection area, the first security detection area detects an unauthorized intrusion, the door is immediately closed, and the alarm sounds long.

3. Drive: DC servo drive system

4. The reaction of the door body in an emergency state: if the door is in operation, there is a sudden power failure, the door wing will stop in the original position and can be pushed freely. According to the requirements, each device can be installed with an emergency button, and the selected button can be activated by pressing the button. Emergency response mode. Generally open the channel in danger or panic. In emergencies such as bandit police, the channel can be manually closed through the remote control button. After the power is turned on or the emergency situation is lifted, the door wing will automatically reset after self-checking without obstacles.
