Problems solved by technology

However, when the existing exhaust fan is performing exhaust work, the operating power is constant, that is, the air output is constant, and the air output is always maintained at a relatively large air output. In practical applications, the number of passengers in the elevator car is always changing. state, when the number of passengers is small, a large air volume is not required, that is to say, the existing exhaust fan cannot control the air volume according to the number of passengers inside the car, so it consumes more energy

Embodiment approach

[0017] Wherein, as an embodiment of the present invention, the exhaust fan 1 is provided with a car closure confirmation module 10 connected to the elevator control system 9 for confirming whether the car door is in a closed state. When the door body is in the closed state, the exhaust fan 1 will control the air output according to the air output level; otherwise, the air output control will not be performed.

[0018] In practical applications, when the elevator car door is opened, people will continue to enter the interior of the elevator. If the air outlet control is used at this time, it will easily cause the electrical components to heat up due to the continuous switching of the air outlet level. Therefore, in order to operate more effectively, the When the elevator door is closed, the corresponding air outlet level control according to the number of passengers is carried out.

[0019] In practical applications, for example, with the same number of passengers, some passeng...

Abstract

The invention provides an energy-saving elevator car ventilation system based on elevator taking people recognition. The system comprises an exhaust fan, an air outlet, an exhaust pipe communicated with the exhaust fan and the air outlet, a camera device and a control center. The control center comprises an image recognition module, a processor module and a database. A people number interval and air outlet grade relation comparison table is stored in the database. The camera device is used for shooting real-time images in an elevator car and transmitting the images to the control center. The control center recognizes the received images through the image recognition module, and specifically recognizes the number of elevator taking people in the images and transmits the number to the processor module. The processor module obtains a corresponding air outlet grade from the database according to the number of elevator taking people. The control center sends the obtained air outlet grade to the exhaust fan, and the exhaust fan conducts air outlet control according to the air outlet grade.

Description

technical field [0001] The invention relates to the technical field of elevator ventilation, in particular to an energy-saving elevator car ventilation system based on passenger identification. Background technique [0002] In order to improve the air inside the elevator car and improve the comfort of the elevator passengers, the existing elevator is equipped with an exhaust fan in the car to ventilate the inside of the car. However, when the existing exhaust fans perform exhaust work, the operating power remains unchanged, that is, the air output volume remains constant, and the air output volume is always maintained at a large air output volume. In practical applications, the number of passengers in the elevator car is always changing. state, when the number of passengers is small, a large air volume is not required, that is to say, the existing exhaust fan cannot control the air volume according to the number of passengers inside the car, so it consumes more energy .
