Knowledge sharing: the working principle and instructions of the automatic sensor door
The translational automatic door unit consists of the following components:
(1) The main controller: it is the command center of the automatic door. Through the large-scale integrated block with internal instruction programs, it sends out corresponding instructions to direct the work of motors or electric lock systems; at the same time, people adjust through the main controller Parameters such as door opening speed and opening range.
(2) Induction detector: It is responsible for collecting external signals, just like people's eyes. When a moving object enters its working range, it will give a pulse signal to the main controller.
(3) Power motor: Provide the main power for opening and closing the door, and control the acceleration and deceleration of the door leaf.
(4) Door leaf running track: Just like a train track, the wheel system of the door leaf spreader restrains the door leaf to travel in a specific direction.
(5) Door spreader walking wheel system: used to hang the movable door leaf, and at the same time drive the door leaf to run under power traction.
(6) Timing belt (some manufacturers use V-belt): used to transmit the power produced by the motor, and to pull the wheel system of the door spreader.
(7) Lower guide system: It is a guide and positioning device for the lower part of the door leaf to prevent the front and rear door body swinging when the door leaf is in operation. When the door leaf is about to complete a door opening and closing, the working process is as follows: when the sensor detects someone entering, it transmits a pulse signal to the main controller, and the main controller informs the motor to run after judging it, and monitors the number of rotations of the motor to notify the motor At a certain time afterburner and into slow running. After the motor gets a certain running current, it runs in the forward direction, and transmits the power to the timing belt, and then the timing belt transmits the power to the spreader system to open the door leaf; after the door leaf is opened, the controller makes a judgment. If the door needs to be closed, the motor is notified to reverse Move towards, close the door leaf.
