The word sensor door should be more common in our life. Large hotels, shopping malls and other sensor door are more likely to appear. While bringing convenience to our life, everything has a shelf life, which requires our careful care to extend the shelf life.
The word sensor door should be more common in our life. Large hotels, shopping malls and other sensor door are more likely to appear. While bringing convenience to our life, everything has a shelf life, which requires our careful care to extend the shelf life. In this issue, the editor will popularize sensor door maintenance knowledge for everyone. If you need it, you may wish to have a look.
I. Sensor door maintenance
the power supply must be equipped with a dedicated line, and it is strictly prohibited to use it with other electrical appliances.
The product can only be used after it is firmly installed and qualified after debugging.
The control box must be installed in a dry and ventilated position. It is strictly forbidden to be close to high-power radio equipment to avoid affecting normal work. When using control button, do not use too much force or too much force to avoid damage.
Door body when running, personnel and vehicles are strictly prohibited from staying on the guide rail. Operators should keep the door body operating conditions at any time to avoid accidents.
The track should be cleaned frequently to avoid the accumulation of debris affecting the operation.
The driver should be filled with grease at least once a year. The chain of sensor door should be filled with lubricating oil frequently, and the wear of each component should be checked. The parts with serious wear should be repaired or replaced in time. When pushing and pulling sensor door, it is light on, off, and slow. It is forbidden to push and pull suddenly, causing damage.
When the product fails, please inform the professional maintenance personnel for maintenance in time, and non-professional personnel are not allowed to open it without authorization.
The above is the introduction of sensor door maintenance knowledge, you can learn about it. Correct maintenance for sensor door can prolong the service life by sensor door.
II. Principle of automatic doors
the opening signal of automatic doors mainly includes two kinds of signals commonly used by microwave radar and infrared sensor. Microwave radar responds to the displacement of objects, so the response speed is fast, it is suitable for places where people with normal walking speed pass through. Its characteristic is that once people near the door do not want to go out and stay still, the radar will no longer respond and automatic door will be closed, it has a certain protective effect on the door machine; The infrared sensor responds to the existence of the object, regardless of whether the person moves or not, as long as it is within the scanning range of the sensor, it will respond to the outgoing contact signal. In addition, if the automatic door receives the contact signal for too long, the controller will think that the signal is input to the system and there is an obstacle. Moreover, if automatic doors is kept open for too long, it will also cause damage to electrical components. Since microwave radar and infrared sensors do not know whether people close to automatic door really want to enter the door, some occasions prefer to use switch button.
Switch button, can be a touch button, more convenient is the so-called touch switch. There is also a handle with a contact switch that provides contact signals to the door machine when the handle is pushed (or pulled in the opposite direction) into place.
The above is the sensor door principle and maintenance method introduced by Xiao Bian. I hope you can understand it. I wonder if it has left a deep impression on you?
