When purchasing a revolving door, it is also equipped with a set of simple revolving door system, which is in line with the requirements of use. Today, the manufacturer of revolving door explains in detail how to connect the controller of revolving door to the auxiliary control device, and then goes to have a look, hoping to be helpful.
1. Signal of door opening
Microwave radar and infrared sensor are two commonly used signal sources: microwave radar is the displacement response and response speed of the object, which is suitable for normal walking speed. Its characteristics are that once the staff close to the door don't want to go out and stay still, the radar will no longer respond, the rotary door will be closed, and the door machine has a certain protective effect. Infrared sensors respond to the presence of objects. No matter whether the person moves or not, as long as the person is within the scanning range of the sensor, the sensor will respond to the contact signal. The disadvantage is that the response speed of the infrared sensor is slow, which is suitable for people who move slowly in and out of the field.
2. Turnstiles for access control systems and non public areas
If the performance and quality requirements of the revolving door are the highest, and it is in the large public area with high frequency of use, then the functional requirements of the revolving door are the highest, and the non-public area is selected for the people in and out. Access control system is the entrance of identity authentication. Provide door opening signal to revolving door control system after identifying or detecting entrance authorization.
The revolving door must be locked before signaling. Access control system includes the simplest key switch, password lock, magnetic card lock. (attendance statistics system). All the way to complex weight recognition system, fingerprint recognition system and so on. However, no matter how complex the system is, it eventually provides a contact signal for the swing door. The shielding of signal circuit is an important measure to avoid the interference of irrelevant signal.
3. The requirement of revolving door is to open it
The coordination relationship between the action and the opening action is applied in the electronic lock of the automatic translation door. The latter is used for heavy-duty automatic sliding door. The electronic lock of automatic sliding door has electromagnetic suction door, electronic door lock and electronic door opener. The direction of electronic door opening force does not affect the opening action and is not easy to operate by mistake. There is also a mechanical lock with a contact switch, so that the re lock is combined with the switch, so that the lock is not in the unlocking state, so that the contact cannot be contacted, and no misoperation can occur.
4. Centralized control
The concept of centralized control includes two meanings: centralized monitoring of the operation status of revolving door and centralized operation of multiple revolving doors. The centralized monitoring of the opening and closing status of revolving door can be used to contact the switch through the position signal output circuit, when the door reaches a certain position, such as the opening position), the touch switch and the contact signal. The induction signal generator can also be used to signal when the sensor detects that the door is in a certain position. The status of the revolving door can be displayed by setting the corresponding indicator light in the central control room, while centralized operation usually refers to opening or locking multiple doors at the same time, depending on whether there are corresponding terminals on the revolving door controller.
