Working principle of automatic door:
1. Door frame and door panel, the door frame is generally a profile or steel structure, and the door panel is generally wood or stainless steel glass.
2. Door operator, track, bracket and belt. The door operator is the motor, which is responsible for the power output of the automatic door. At the same time, there are many interfaces on it, such as the backup power interface, multiple switches and remote control interfaces; the track is the automatic door sliding, Slide over the moving rail; the bracket is where the automatic door is supported, and the belt is the drive chain that connects the engine to the automatic door
3. The switch has contact type, infrared sensor, microwave sensor, touch sensor, foot sensor, password, card, face, fingerprint, remote control, attendance and other automatic door switches are optional, these switches are connected to the motor , which controls the operation of the motor, that is, the switch of the automatic door
4. The safety light or light curtain is installed in the operating range of the automatic door and is also connected to the door operator to ensure that the automatic door will not close when there are people or objects
5. Electric locks are used to lock automatic doors to prevent manual opening. There are electric mortise locks, magnetic locks, etc., which are also connected to the door operator
6. If it is a glass door, pictures or words must be pasted on it to prevent people from hitting the glass door directly and causing unnecessary losses.
7. In order to ensure that the automatic door can work normally when the power is cut off, it can be equipped with a backup power supply
Unlock
1. The coordination between the automatic door unlocking action and the door opening action, the electronic lock applied to the automatic translation door has three types: the electromagnetic lock of the lock belt, the electric lock of the lock body hanging part, and the lock motor. There is also a mechanical lock with a contact switch, which combines the lock with the switch. When the lock is not in the unlocked state, the contacts cannot be contacted, and the motor cannot be misoperated.
2. Microwave sensor 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 the people near the door do not want to go out and stay still, the radar will no longer respond. , the automatic door will be closed, which has a certain protective effect on the door operator.
3. The infrared sensor responds to the existence of objects, no matter whether the person moves or not, as long as it is within the scanning range of the sensor, it will respond and send out a contact signal. The disadvantage is that the response speed of the infrared sensor is slow, and it is suitable for places where people with slow movements enter and exit.
4. Install access control system and electric lock: install automatic door in self-service bank, you can increase the installation of self-service bank access control system and install electric lock, so as to realize the control of entry and exit
The key switch can be a contact button, more conveniently a so-called elbow switch.
The key switch can be a contact button, more conveniently a so-called elbow switch. The elbow touch switch is very durable, especially it can be operated with the elbow, avoiding the contact of the hand.
There is also a foot switch, which has the same function, but has higher requirements for waterproofing, and the power of the pedal is very large, which can easily cause the foot switch to fail. There is also a handle with a contact switch, which provides a contact signal to the door operator when the handle is pushed (or pulled in the opposite direction) into place.
Building automation sometimes puts forward special requirements, such as using a branch line of the telephone to control the opening of the door. To meet this requirement, just ensure that the signal is a passive contact signal. In some cases, a request is made for remote control of the antenna. Use a wireless receiver to make a contact connection with the automatic door, and then match a wireless transmitter to meet the requirements.
