1. What is the principle of the automatic sensor door?
The automatic sensor door is that when a moving object approaches the door, the door can be automatically opened and closed. The automatic door itself is equipped with an induction probe, which can emit an infrared signal or a microwave signal. When this signal is reflected by an object close to it, it will automatically open and close.
2. What is the structure of the automatic sensor door?
There are many types of automatic induction doors, and their structures are also diverse. Taking the translation type induction automatic door machine as an example, the components are as follows:
1. Main controller: It is the command center of the automatic door. Through the large-scale integrated block programmed with instructions inside, it issues corresponding instructions to direct the motor or electric lock system to work; at the same time, people adjust the door leaf opening speed, Enable parameters such as amplitude.
2. Induction detector: There are two main types: microwave sensor and infrared sensor. It is responsible for collecting external signals, just like people's eyes, when a moving object enters its working range, it will send a pulse signal to the main controller.
3. Power motor: provide the active force for opening and closing the door, and control the acceleration and deceleration of the door leaf.
4. Door leaf travel track: Just like the rails of a train, the spreader wheel system of the door leaf is constrained to make it travel in a specific direction.
5. Door spreader running wheel system: used to hang the movable door leaf, and drive the door leaf to run under the power traction at the same time.
6. Synchronous belt (some manufacturers use V-belt): used to transmit the power produced by the motor, and to drive the wheel system of the door spreader
7. The lower guide system: it is the guide and positioning device of the lower part of the door leaf, which prevents the front and rear door body from swinging when the door leaf is running.
8. The automatic door is equipped with a sensor door machine, which is a collective name for a series of components that control the opening and closing of the automatic door; Wheels, belts, rails.
