Parking barriers: I have special anti-smashing skills
Barrier gates can be said to be the representative characteristics of the access control and parking lots in most people's impressions. In the general parking system, barriers also play an absolute role. From the initial human button control, remote control, to IC card barriers, Bluetooth sensor barriers, to today's license plate recognition systems, even if the parking system is changing rapidly, the barrier remains a guardian role in the parking system. However, in daily use, how can we ensure that the barriers will rise and fall in order to be able to release the vehicles without causing damage to the released vehicles due to premature drop of the rods? Today Xiao Bian introduced several common parking barriers to prevent car crashes.
The sense of flood control technology General parking lots are equipped with a sense of place. When the vehicle detector detects a sense trigger signal, it will control the brake bar to always rise and maintain the vertical state. As long as the sense signal disappears, it will drop. The key to this kind of flood prevention technology lies in the stability of the geomagnetic coil. If the ground disturbance is felt, it may fail, and the ground sense can only detect the vehicle and does not have the function of flood prevention.
Infrared ray prevention This method is installed in both sides of the entrance and exit barrier infrared device, in the process of falling gate bar, if the vehicle enters, infrared blocked, the bar will automatically rise, the reaction is more rapid. However, the range of infrared radiation is small, and it is easily disturbed by rain and snow.
The prevention of pressure wave flooding is also called resistance prevention. It is mainly the installation of a resistance-resisting return device. When the gate is in contact with the vehicle or pedestrian (the contact pressure is adjustable), the rubber bar under the device is under resistance. The intelligent resistance-resisting return device immediately converts the falling-lever state to a kick-up state, and the barrier raises to prevent the brake from being dragged.
Digital flood prevention technology is relatively safe, of course, the cost is relatively high, digital automatic inspection and anti-smashing car measurement technology, without other auxiliary protection devices, real-time accurate acquisition of gate operation data monitoring and operation, once blocked during operation, brake The rod will rise quickly.
