What are the advantages of automatic door lock?
1, automatic door lock
Speaking of automatic door lock, it is obvious that its heart is a lock, its characteristic is automation, and its use is only on the door. No matter what door it is, as long as it is a door, you can use the automatic door lock.
2. Convenient access
The general feature of automatic door lock is that it is particularly convenient. It is not allowed to spend so much time when going out or entering the door, which can save a lot of time for office workers, especially in the morning.
3. Strong flexibility
Automatic door locks are very flexible. There is a magnet sensor inside, which can judge according to the relevant information, so as to open and close the door in the shortest time, which many locks can't do.
4. Excellent guidance
Because the automatic door lock needs to be opened and closed frequently, its parts must be of particularly good quality to be used for a long time, and its guidance is undeniable.
Types of automatic door locks
1, mortise lock: most of the earliest automatic doors were realized by mortise lock, and there are two kinds of special and non-special doors on the market. Special mortise lock is an electric lock specially designed for the characteristics of automatic doors. Originally imported from Taiwan Province Province, this lock can be applied to various brands of automatic doors.
The working principle is that the sensor or brake controller (such as self-service bank credit card reader) sends a signal to the electric lock, which unlocks after receiving the signal, and then sends a signal to the automatic door to open it.
Because the lock is unlocked first, then the control unit of the lock sends a signal to the door crane controller to open the door, which avoids the lock collision caused by the lock not jumping when opening the door. Moreover, the control unit of the lock has the function of delaying the output of the door opening signal, so it is called special electric lock. 2. Magnetic lock: Like latch lock, magnetic lock can be divided into two types according to whether it is designed as an automatic door or not, but the way to lock the door is to lock the door through the lock head (tongue) and attract the door body by generating magnetic force.
The advantage of magnetic lock is that the door is closed and there is no movable gap, which prevents the failure caused by children's sliding door. The disadvantage is that the door can be pulled open when the bearing capacity is exceeded.
Structure and working principle of automatic door lock
The automatic door lock system consists of permanent magnet bidirectional motor, conductor, relay and connecting rod control mechanism.
Hydromagnetic motors do not need grounding wires. Like electric doors and windows, it determines the rotation direction of the motor through the current direction of two motor wires. Some car automatic door lock systems do not need to be equipped with relays, such as two-door cars, because two-door cars only have two motors, and the current passing through them is very small, so their switches will not be overloaded; Four-door cars are different, because they use a lot of motors, and usually need to control the relay through the door lock switch.
Then control the current flowing into the motor. Because the door lock mechanism consumes a lot of current when working, in order to shorten the working time, a timing device is installed in the door lock circuit. The working principle of the device is mainly to use the gram discharge characteristic of the capacitor, when the power supply is turned on for more than a specified time. The current transmitted to the door locking mechanism will be automatically interrupted, and the normal door locking or opening will also be automatically interrupted. The timing device can protect the safety of circuits and electrical appliances.
Automatic door electronic lock of access control system
There are many things to consider in the electronic lock of automatic door in access control system. In order to give readers a clear idea, I will describe it to you through an authorized person's door-entry operation: (1) The authorized person will give the electronic lock an unlocking signal through the access control system-(2) The electronic lock will be opened after the authenticity is confirmed-(3) When the electronic lock is confirmed to be opened, a pulse door-opening signal will be generated and sent to the automatic door-it should be noted that in the fourth and fifth steps, In the meantime, if someone follows the automatic door, it needs to be opened again to play the role of anti-pinch (this function is not needed in some places). As for other functions such as remote control, professionals should be able to know how the whole process is realized, so I won't describe it too much here.
