How does the elevator level automatically?

There are magnetic switches or photoelectric induction switches on the elevator car, and each floor of the elevator has plane information (magnetic beans). When the position of plane information is consistent with the adjustment of magnetic switch or photoelectric induction switch, it is a plane state.

Once the leveling information and the magnetic switch are displaced, the computer will think that the car has left the leveling position and needs compensation, and the computer will tell the motor whether to pull up or put down.

In order to stop the elevator accurately, the flat floor is divided into two steps, first slowing down and then stopping.

Adjust the leveling distance according to the load. The leveling process is to adjust the deceleration distance of leveling according to the load, that is, the heavier the passenger, the farther the deceleration point is from the leveling position. The speed after deceleration has also been adjusted, that is, the heavier the passenger, the lower the arrest speed. Because the speed after deceleration is more difficult to adjust than the distance, it is only used in higher-grade elevators.

Extended data:

Elevator is generally driven by traction. The traction machine is used as the driving mechanism, and the steel wire rope is hung on the pulley of the traction machine, with one end hanging the car and the other end hanging the counterweight device. When the traction machine rotates, the traction force is generated by the friction between the wire rope and the pulley, which drives the car to move up and down.

Basic leveling function of elevator:

1, automatic floor leveling function after call-back: the elevator automatically starts running after call-back, and floors are leveled;

2. Power-off automatic leveling function: When the elevator power supply network fails, power is supplied through the power cabinet (ALP) configured by the elevator, and the elevator will run to the nearest service floor at a low speed, and the leveling floor will stop and open the door.
