The floor identification subunit obtains the floor information by detecting the identification plate on the car through the position switch set at the floor door to confirm the floor.

[0033] Working principle: After the elevator user calls the elevator, the central control module controls the car to move to the calling floor. The door opening management unit generates a door opening command after identifying the correct floor information. Then the elevator car carries people, goods, or a mixture of people and goods. The load identification module identifies the transportation situation in the car through the collected images, and generates loading identification results including people, goods, or a mixture of people and goods. The central control module controls the car to move up and down according to different identification results.

[0034] When it is recognized that the elevator is transporting people, the car door management module automatically closes the door, and the central control module controls the car to move to the target floor;

[0035] When it is identified that the elevator is transporting cargo or a mixture of cargo and people, the car door management module generates a manual door closing command after receiving the manual door closing signal generated by the manual door closing sub-order, closes the car door, and then the central control module controls the car to move to the target floor.
