Automatic door signal - Microwave radar - infrared sensor - contact switch - foot sensor switch - automatic door opener switch - timer:
Automatic door microwave radar and infrared sensors are two common sources: 1,automatic door microwave radar
is the object displacement reaction of the automatic door, with the rapid reaction speed,
automatic doors is suitable to used for the place where people go through with a normal walking speed , the characteristics
of automatic doors is that once the staff who is near the door did not want to go out and stationary, the
radar will no longer respond, the system will automatically close the door on the automatic
in order to have a protective effect on automatic door; 2, Infrared sensors to react to the existence of objects,
regardless of movement of personnel and not, as long as the person is in the scan range of the sensor,
automatic door contact will respond to semit the signal, its drawback is that infrared
automatic door sensor response speed is slow, which is suitalbe to be used for the place where slow moving person go
through. In addition, if the automatic doors accept the contact signal for too long, automatic
door controller will vier it as be obstacles of the input system . And if the automatic sliding door remains
open for too long, the door will automatically cause some damage to electrical components.
Automatic doors automatic timer can control the state of the door, the principle is the
clock switching circuit is connected with a specific, pre-set time will be automatically in the open or lock the door statement for
automatic doors.
Now the building automation sometimes has special requirements, automatic door
opening signal is contact signals, such as using the telephone line control of a sub-door,
to meet this requirement, as long as the signal is the signal contacts that can be passive. In
some cases, people will have some requirements on the antenna remote control. A wireless receiver
connected with the automatic doors to contact with the connection, adding a wireless transmitter, you can
meet the requirements. However, the automatic doors of the radio wave sources are now too
easy to accidentally open the door leading to a troublesome problem.
Automatic doors of microwave radar and infrared sensors automatically close the door do not
know whether you really want to the door, so some occasions, more willing to use the key
switch. Automatic door button switch can be a contact type button, automatic doors is more
convenient to the so-called elbow touch switch. Automatic door elbow touch switch is
durable, in particular, it can be used to operate the elbow, to avoid hand
contact. Another one is foot switch, the same function, but waterproof demand is high, and the great force of pedal, easy to
pedal the switch under being deactivated. There is a kind of automatic door
contact switch handle, when the handle was pushed (or pulled in the opposite direction) in
place to provide door contact signal. http://www.adoorwin.com/
