With the development of science and technology, people not only have induction lamps in their lives, but also invented induction doors. You can see them in large hotels, office buildings, banks and other places. When someone approaches the door, the door will automatically open. Do you know the principle of automatic door? Now let's introduce the principle of automatic door sensor and its price

with the development of science and technology, people not only have induction lamps in their lives, but also invented induction doors. You can see them in large hotels, office buildings, banks and other places. When someone approaches the door, the door will automatically open. Do you know the principle of automatic door? Now let's introduce the principle of automatic door sensor and its price

I. principle of automatic door sensor

automatic door sensor can be divided into ultrasonic sensor, remote control detector, infrared sensor, microwave sensor, blanket sensor and pull switch sensor due to different uses

next, we will take the translational induction automatic door machine as an example to introduce the basic working principle of the automatic door machine

the translational automatic door unit is composed of main controller, induction detector, power motor, door leaf travel track, door leaf spreader pulley system, synchronous belt, lower guide system and other components

when the induction detector detects that someone is about to enter, it sends the signal to the main controller. After receiving the information, the main controller immediately informs the motor to run and monitors the number of revolutions of the motor through judgment, informing the motor to accelerate or slow down at a certain time. After receiving the information and some current, the motor moves forward and transmits the power to the synchronous belt. The synchronous belt transmits the power to the spreader system to open the door leaf. After the door leaf is opened, the controller determines whether it is necessary to close the door. If it is necessary to close the door, the controller notifies the motor to move in the opposite direction and close the door leaf, so on

II. Price of automatic door sensor

the following is the online quotation of some automatic door sensors. You can refer to it (the specific price is also subject to the sales of physical stores):
