Automatic doors can be categorized as revolving doors, curved doors, sliding doors, induction electric doors, overlapping doors, folding doors, 90°sliding doors, and high-speed doors.
How automatic doors work:
1. Door frame and door panels. The door frame is typically made of profiled material or steel, while the door panels are typically made of wood, stainless steel, or glass.
2. Door operator, track, bracket, and belt. The door operator is the motor responsible for delivering power to open and close the automatic door. It also has many interfaces, such as a backup power supply, multiple switches, and remote control interfaces. The track is the rail that the automatic door slides back and forth on. The bracket supports the automatic door, and the belt is the drive chain connecting the motor and the automatic door.
3. Switches: There are contact-type, infrared, microwave, touch, foot, password, card, facial, fingerprint, remote, and attendance sensors. These switches are all connected to the motor and control the operation of the motor, which in turn opens and closes the automatic door.
4. Safety lights or light curtains are installed within the operating range of the automatic door and are also connected to the door operator to prevent the automatic door from closing when someone or something is in the way.
5. Electric locks: They are used to lock the automatic door to prevent it from being opened manually. Examples include electric bolt locks and magnetic locks, and they are also connected to the door operator.
6. If it is a glass door, be sure to apply pictures or text to it to prevent people from bumping into it and causing unnecessary damage.
7. To ensure normal operation during power outages, automatic doors can be equipped with a backup power supply.
Unlocking
1. Coordination between unlocking and opening actions for automatic sliding doors. Electronic locks used for automatic sliding doors include electromagnetic locks with a belt lock, electric locks with a door body hanger, and motor locks. There are also mechanical locks with contact switches, which combine the lock and switch. Unless the lock is unlocked, the contacts cannot make contact, preventing motor misoperation.
2. Microwave radar reacts to the movement of objects, resulting in a fast response speed. It is suitable for places with people walking at a normal speed. Its characteristic is that if a person near the door stops and does not want to exit, the radar will no longer react, and the automatic door will close, providing a certain degree of protection for the door operator.
3. Infrared sensors react to the presence of objects. Regardless of whether a person is moving or not, as long as they are within the sensor's scanning range, they will react and send a contact signal. However, their disadvantage is that infrared sensors have a slow response speed and are suitable for places with slow-moving people entering and exiting.
4. Install an access control system and electric locks: When installing automatic doors at a self-service bank, you can add an access control system and electric locks to control access.
The pushbutton switch can be a contact-type button, or a more convenient elbow-touch switch.
The pushbutton switch can be a contact-type button, or a more convenient elbow-touch switch. Elbow-touch switches are durable, especially because they can be operated with the elbow, eliminating hand contact.
Foot switches also offer similar functionality, but require higher waterproofing requirements. Furthermore, the high pressure from the foot pedal can easily cause the switch to fail. Another type of handle with a contact switch provides a contact signal to the door operator when the handle is pushed (or pulled) into position.
Building automation systems sometimes have special requirements, such as using a branch line from a telephone to control door opening. This requirement can be met by ensuring the signal is a passive contact signal. In some cases, antenna remote control is required. This requirement can be met by using a wireless receiver with a contact connection to the automatic door, coupled with a wireless transmitter. Automatic Door Opening Signal:
The automatic door opening signal is a contact signal. Microwave radar and infrared sensors are two common signal sources.
Microwave radar responds to the movement of objects, resulting in a fast response. It is suitable for places with people walking at a normal speed. Its characteristic is that if a person near the door stops moving and does not intend to exit, the radar will no longer react, and the automatic door will close, providing some protection for the door operator.
Infrared sensors respond to the presence of objects. Regardless of whether a person is moving or not, as long as they are within the sensor's scanning range, they will respond and transmit a contact signal. However, their slow response speed makes them suitable for places with slow-moving people entering and exiting.
Furthermore, if the automatic door receives a contact signal for too long, the controller will interpret it as a problem with the signal input system. Furthermore, if an automatic sliding door remains open for too long, it can damage the electrical components. Because microwave radar and infrared sensors cannot determine whether a person approaching the automatic door actually intends to enter, a pushbutton switch is preferred in some situations.
