High-precision self-detection type elevator car

Abstract

The invention relates to a high-precision self-detection type elevator car. The elevator car is based an existing elevator car structure, a high-precision detection device is introduced, a pressure sensor (4) is adopted and is matched with a designed treading bottom plate (3), and therefore the real-time loading weight inside a car body (1) can be accurately acquired; and in addition, a plurality of sets of laser transmitting and receiving devices linked in the up-down direction for collecting the lasers are designed on the basis of the area division of the treading bottom plate (3) to realize the accurate detection of the inner space of the car body (1). In this way, comprehensive analysis is realized on the basis of multi-level detection of the load weight and space, the internal loading condition of the car body (1) is accurately known, and therefore the working efficiency of actual operation of the car body (1) is improved, and a passenger or a person waiting for an elevator can be given the most objective and accurate prompt.

Description

technical field [0001] The invention relates to a high-precision self-checking elevator car, which belongs to the technical field of elevators. Background technique [0002] Elevator is the product of the improvement of technology level and people's quality of life. Elevator is used to realize fast passage between floors, which is convenient for people. Elevator includes escalator and vertical elevator, each with its own unique advantages, but in practice In the application, the shortcomings of the existing elevators can still be found. As we all know, the elevators as public facilities serve many people every day. Look, it is judged by knowing whether the weight in the elevator car has reached the maximum load, and the reminder given to passengers is only whether it is overloaded. Such simple information lacks accurate judgment. For example, when the elevator car is loaded with goods, occupying Inside the entire car, if the maximum load is not reached, the car will still r...

Such simple information lacks accurate judgment. For example, when the elevator car is loaded with goods, occupying Inside the entire car, if the maximum load is not reached, the car will still respond to floor requests during operation, which not only affects work efficiency, but also sends wrong reminders to users waiting for the elevator
