With the development of science and technology, people not only have sensor lights in their lives, but they have also invented induction doors. They can be seen in large hotels, office buildings, banks and other places. When we talk about this, we have to mention the automatic door sensor. Is it really good? Today we will work together to understand the relevant content of the automatic door sensor .
How automatic door sensors work
The translational automatic door unit consists of a main controller, an inductive detector, a power motor, a door fan running rail, a door fan sling running wheel system, a timing belt, and a lower guide system.
When the sensing detector detects that someone is about to enter, the signal is transmitted to the main controller. After the main controller receives the information, the main controller informs the motor to run and monitors the number of rotations of the motor to notify the motor to accelerate or slow down at a certain time. After the motor obtains information and some currents, it makes a positive movement, transmits the power to the timing belt, and the timing belt transmits the power to the spreader system to open the door leaf. After the door leaf is opened, the controller determines whether the door needs to be closed. If the door needs to be closed, The controller then notifies the motor to move in the reverse direction, closes the door leaf, and so on.
Automatic door sensor type
1, from the microwave sensor: also known as microwave radar, the object response to the movement, so the reaction speed, apply to the normal speed of the passage of the staff, it is characterized by once the door does not want to go out and do not stay static Moving, the radar no longer responds, the automatic door will close, and there may be a phenomenon of clips.
2. Infrared sensors: React to the presence of an object. Regardless of whether or not the person moves, it responds as long as it is within the scanning range of the sensor. Infrared sensors have a slower response than microwave sensors and have a full range of 12°--20° in the longitudinal detection range.
How to maintain the automatic door sensor
Clean the oil and dust inside the chassis; check the wear of various parts of the automatic door sensor, check the deviation of the support position of the automatic door and the tightness of the screw; check the tightness of the belt; check the output of the controller, open/close door width, speed, brake Such as circumstances; Check voltage parameters are normal; Repair, replace damaged parts; Owners also need to pay attention to the regular maintenance and maintenance of automatic doors, due to the installation of automatic doors and the use of the environment, the use of the process will inevitably cause problems.
With regard to the automatic door sensor , I will introduce it to you. I hope to help you, and I would like to look forward to seeing more information on this site.
