Several ways to control the high-speed rolling door


Nowadays, the high-spped doors are widely used in food, chemical, textile, electronics, supermarket, refrigeration, logistics, warehousing and other places due to their light weight, fast operation, flexible operation and long service life. As the name implies, the main feature of the fast rolling door is “fast”, which is closely related to his control system. In addition to our most commonly used remote control and button control, we can equip different control methods according to different industries.


1. Geomagnetic ring: The principle is that through the passing vehicle, its metal fittings will change the value of the ring sensor and send a signal at the same time. After determining the shape of the electromagnetic ring, it must be grooved on the ground to be installed.


2. Infrared: When entering the sensing range, the sensor detects the change of the infrared spectrum and automatically turns on the load. After leaving, the delay automatically turns off the load. However, the sensitivity of the detection is easily disturbed by various heat sources and light sources.


3. Radar induction: After the sensor switch is turned on, during the delay time period, if someone or an object moves, the switch will continue to be turned on until the person or object leaves and delays the time. The sensing distance is long, the angle is wide, there is no dead zone, and it can pass through obstacles of different thicknesses, which are less affected by environment and temperature.
