automatic door system configuration

Automatic door system configuration: 
Automatic door system configuration is used according to requirements and equipped with theautomatic door controller connected to the external auxiliary control devices, such as open source, access control systems, safety devices, centralized control. Must configure a reasonable auxiliary contro basing on use of the building characteristics, the composition of staff, the building automation system requirements. Automatic doors installation company should be responsibility to fully understand the user's system requirements on the basis of a reasonable and economical to the user's system configuration.
1, Opening signal 
    Automatic door opening signal is the contact signal, microwave radar and infrared sensorsare two common sources.
    Automatic door microwave radar and infrared sensors are two common sources: microwave radar automatic door is the object displacement reaction, which reaction speed automatic doors, automatic doors for a normal person walking speed through the place, the characteristics of automatic doors Once the door is near the staff did not want to go out and stationary, the radar will no longer respond, the door will automatically close the door on the automatic door has a protective effect; infrared sensors to react to the existence of objects, regardless of movement of personnel and No, as long as the scan range in the sensor, automatic door contact will respond that the signal came. Drawback is that infrared automatic door sensor response slower, automatic doors for a slow-moving staff out of place. In addition, if the automatic doors to accept the contact signal for too long, automatic door controller that the input system obstacles. And if the automatic sliding door remains open for too long, the door will automatically produce 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 automatic doors automatically open or lock the door in the state.
Now the building automation is sometimes put forward 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 can be passive. In some cases, people will move the antenna remote control requirements. A wireless receiver with 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. Automatic doors to avoid hand contact. There foot switch, the same function, but water demand is high, and the power of a great pedal, easy to pedal the switch is 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.
2, The access control system  and the automatic door in non-public areas.
   If have the highest performance and quality requirements of the automatic doors in the high frequency use of large public areas, so that automatic control function of the automatic door to the most demanding of the staff selects non-public areas. Access control system is for entry identification authorized. The control system  provides the automatic door opening signal after the entry identification or detection authorized. Before providing the signal to open the door automatically, the door must be in the locking state. Access control systems ranging from simple key switch lock, code lock, magnetic card lock, to the complex weight identification system, fingerprint identification systems, but no matter how complex the system is, the ultimate is that the contact signal provides the signal to automatic doors for opening. Signal circuit shielding can avoid interference from extraneous signals to open the door incorrectly,which is very important.
3, Automatic door lock function is to unlock and open the door movement in coordination state between them.
  Automatic sliding door electronic lock ,includes magnetic lock (belt lock) and electromagnetic lock (hanging parts set lock). The later one is used to heavy-duty automatic sliding doors. Automatic swing door electronic lock,includes magnetic suction, electronic latch locks, electronic door lock device, also known as hiden lock. Force direction won't affect the door opening movement, can avoid to misuse. Another one is a mechanical lock with a contact switch, the lock combination with the switch, the lock is not unlocked, the contacts can't be touched,  misuse can not happen.
4, Centralized control of the automatic door system.
The concept of centralized control, including centralized monitoring and centralized operating multi-automatic doors running. open To centralized monitoring the automatic doors  state of open and close via signal output circuit to achieve, can adopt the touch switch, when the door reaches a certain Location (eg, open position), the touch switch issues a contact signal. Also can use inductive signal devices, sensors detect the door in a position, to issue the signal, set the appropriate indicator in the control room , can display the status of automatic doors.As usual,centralized control means to open or lock the number of doors, depending on whether the automatic door controller has the corresponding terminals.
    Automatic doors is the small proportion throughout the building investment, but plays an important role in the daily use of the construction and management, is an important indicator of the level of building intelligent.From the construction aspect, automatic doors is more complex and comprehensive work, with external decoration, interior decoration, strong power, weak power, building self-control, and even closely related to the fire system. More importantly, the installation of automatic doors are usually in the later part of the building decoration, if project co-ordination is adverse, may affect the overall project schedule. 
    Automatic door industry is in the rapid development in the world, the direction of development, on the one hand is procedures for the function of control and digital for state display, to provide for the possibility of developing more features; the other hand, is to improve the structure of the door machine and to improve the design of the door body, in order to adapt to different architectural styles.
