Automatic door signal - Microwave radar - infrared sensor - contact switch - foot sensor switch - automatic door opener switch - timer:

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/

automatic door operator

Automatic door operator application:
Economic is increasing,the technology is developing,our life is improving day by day,step out from one day to enter another door,you always  enjoy the convenience spring from the technology-automatic door operator,which is used for control the glass or wood door leaves to open and close,maybe sliding,maybe swing,maybe folding,maybe revolving,etc.The main principle of the automatic door operator is similar for them.When one set of complete system of automatic door operator is installed overhead the door leaves,the microwave sensors or infrared sensors installed overhead the door frame,will detect the moving object or person body,then give one signal to micro-computer controller,the signal will be conducted on motor,the motor will run,taking the belt,belt connectting with the fixed hardware (with wheels/rollers)of the door leaves,then the whole automatic door operator system will work automatically.Additionally,the micro-computer controller can be integrated with others more functions via writing different programmes.Basically,remote controller will be matched for it,sometimes,safety beam sensor(electronic eye) will be used for safety access.
Anyway,the automatic door operator will be used more and more widely,since very convenient,can meet lots of demands,from security to access record,and sometimes,the automatic door operator system is like one kind man,gives a favor to children and inconvenient persons.
So,we, Adoorwin Industrial,are always viewing the project of automatic door operator as be a loving care project,acting with love to serve this world.

what is the automatic door system?

Automatic doors Systems on the building began to be used in the later years of the twentieth century.
The late 1920s, the U.S. supermarket opening automatic doors began to be used, affected the
world's first brand DORMA automatic doors in 1945, developed a hydraulic, air automatic doors,
 the new main entrance of the building began to use. To the 1962 electrical-style has begun
 to appear, along with the city after the construction of automatic doors technology field is increasing every year.

At first, the supply of buildings with a power supply with motor speed control is difficult, and can only hydraulic,
pneumatic speed control, but the energy conversion efficiency is very low, but along with the technical development of
electrical control, electrical control technology has now matured , direct control automatic door motor electrical
gradually become mainstream. For example: all kinds of automatic control with identifiable special doors,
such as: automatic door sensor (infrared sensor, microwave sensor, touch sensors, foot sensors),
credit card automatic doors. The use of pedals, effects such as optical beam to power, pneumatic or hydraulic-powered
automatic doors open and close the system. 1st century AD, Greek Hero automatically open the temple's construction of
the device (Figure 1) was the first use of pneumatic and hydraulic-powered automatic doors. As shown,
the altar fire to an expansion of the air, water flows into two, using the weight of the water rotating
shaft 3, open the door. Altar fire, the door automatically closed. Modern automatic door operation,
there are three main ways (Figure 2).
① foot plate: equipped with a pressure switch under the pedal.
② optical beam type: near the door of the optical beam transmitter and sensing devices.
③ button way: by hand to make a similar switch the button to open doors. Automatic doors to sliding,
hinged or folding doors open and close, etc.. For security, must be equipped with special equipment,
such as family needs with the installation of automatic doors come on the identification device or TV monitor,
etc., persons outside the family strictly limited. Automatic doors in shopping malls, hotels, restaurants,
airports, railway stations, banks and other occasions, has been widely used. Automatically open and close
 by a variety of signal control, and have run the unit, sensors and door components in general.
