Method for detection of passenger space in elevator car

Abstract

The invention discloses a method for detecting the manned space of an elevator car. The current image of the car is transmitted to an image comparison system through an image capture device, and compared with a reference comparison image, and the current interior space of the car is calculated. The utilization rate is transmitted to the control system, and the control system calculates and analyzes the received signal, judges the use status of the car interior space, and can accurately calculate the utilization rate of the car interior space according to the comparison between the current car image and the reference comparison image , the control system can judge the use of the internal space of the car according to the car weight detection device to perform corresponding operation control. The elevator car manned space detection system can realize high-precision detection of the available space of the elevator car, and the system structure is simple. Moreover, the detection results are reliable and stable, and at the same time, it can provide a reliable basis for the elevator to carry out control calculations such as full-load direct driving and group control distribution, improve the operating efficiency of the elevator, and provide passengers with a better riding experience.

Description

technical field [0001] The invention relates to the technical field of car load detection, in particular to a method for detecting the passenger space of an elevator car. Background technique [0002] At present, in the elevator industry, the detection methods of the elevator control system for the passenger capacity of the car mainly include: measuring the load in the car through a weighing device; calculating the number of people entering and leaving the car through an intelligent light curtain or other similar sensors, the above Both methods can only indirectly obtain the number of people in the car. If the passengers in the car carry large luggage or goods, although the rated load or number of people has not reached the rated load, the available space in the car can no longer be used. Other passengers continue to enter. For this situation, the existing elevator control system does not have a reliable means to detect and control. Moreover, when the elevator is equipped wi...

[0002] At present, in the elevator industry, the detection methods of the elevator control system for the passenger capacity of the car mainly include: measuring the load in the car through a weighing device; calculating the number of people entering and leaving the car through an intelligent light curtain or other similar sensors, the above Both methods can only indirectly obtain the number of people in the car. If the passengers in the car carry large luggage or goods, although the rated load or number of people has not reached the rated load, the available space in the car can no longer be used. Other passengers continue to enter. For this situation, the existing elevator control system does not have a reliable means to detect and control. Moreover, when the elevator is equipped with full-load direct driving function, peak operation function, group management control function, etc., it needs to pass through the elevator. When the number of people in the car is used to control and judge the function, this situation will cause the control system to fail to correctly identify the situation in the car, making the above functions unable to function normally
