Elevator with passenger state recording and display functions

Abstract

The invention provides an elevator with passenger state recording and display functions. The elevator comprises a lift car and a suspended ceiling, wherein a pressure sensor is arranged at the bottom of the inside of the lift car; an infrared sensor and a human body sensor are arranged at the top of the lift car; first detection areas are formed by intersections of an induction area of the pressure sensor and an induction area of the infrared sensor, and the space in the lift car is uniformly divided into at least two first detection areas with equal sizes; an analysis box used for drawing a state analysis chart indicating the distribution state of people in the elevator in real time according to data acquired by the pressure sensor and the infrared sensor in real time is arranged outside the top of the lift car. The elevator has the advantages that detection results are accurate, an output image is visual, rescuers can be assisted in rescuing effectively and the like.

Description

technical field [0001] The invention belongs to the field of elevators, in particular to an elevator with the function of recording and displaying passenger loading status. Background technique [0002] In the event of an accident, the elevator generally does not allow the trapped people in the car to leave the car without authorization, because this will increase the risk of secondary injury, so it is generally necessary to wait for rescuers to arrive for rescue, but the elevator itself is a metal box. Its shielding is very good, so it is difficult for rescuers to communicate with internal personnel through electronic equipment. At the same time, the escape exit is set on the top of the car, and there is no climbing tool in between, so when rescuers do not know the elevator car When the situation inside the car is lowered directly from the escape hatch for rescue, the internal personnel will be confused and other accidents will occur. Therefore, it is necessary to design a ...
