Sliding door operator
Encyclopedia
A sliding door operator (or sliding door opener or automatic sliding door operator) is a device that operates a sliding door
for pedestrian use. It opens the door automatically, waits, then closes it.
s.)
They are also used in elevators (lifts)
A trigger from any of the above requests that the door be opened (or reopened if it was closing).
The simplest sensor is a light beam across the opening. An obstacle in the path of the closing door breaks the beam, indicating its presence. Infrared
and radar
safety sensors are also commonly used.
A motor, geared down to get a lower speed and a higher torque, drives a pulley at one end of a belt. The door is clamped to the belt.
To open the door, the motor turns the pulley, which in turn turns the belt, which in turn drags the door. To close the door, the reverse occurs.
Historically, elevator doors were opened by a set of mechanical linkages; the motor, geared down, would rotate linked arms, which in turn would drive the door.

Triggering
A door operator may be triggered in various ways:- Approach Sensor (such as a radar sensor) - the door opens when a user approaches it.
- Pushbutton - the door opens when a user presses a button.
- Access control - the door opens when the an Access Control SystemAccess controlAccess control refers to exerting control over who can interact with a resource. Often but not always, this involves an authority, who does the controlling. The resource can be a given building, group of buildings, or computer-based information system...

A trigger from any of the above requests that the door be opened (or reopened if it was closing).
Safety sensors
A sliding door operator reopens the door if it closes into an obstacle. However, most operators use sensors to prevent the door from ever coming into contact with a user in the first place.The simplest sensor is a light beam across the opening. An obstacle in the path of the closing door breaks the beam, indicating its presence. Infrared

safety sensors are also commonly used.
Collision Detection
It is an additional security way if anyhow an object could not detect by safety beam or curtain, The BLDC motor counts error while hitting the object then processor decides to open back the door leafs.Technology
The operator is placed in the space above the sliding door.A motor, geared down to get a lower speed and a higher torque, drives a pulley at one end of a belt. The door is clamped to the belt.
To open the door, the motor turns the pulley, which in turn turns the belt, which in turn drags the door. To close the door, the reverse occurs.
Historically, elevator doors were opened by a set of mechanical linkages; the motor, geared down, would rotate linked arms, which in turn would drive the door.
