Inductive elevator operating panel

Abstract

The invention discloses an inductive elevator operating panel, and belongs to the technical field of elevator accessories. The inductive elevator operating panel comprises a detection unit, a control unit and a simulating key panel, wherein the detection unit is mounted on the inner top wall of a cage and is electrically connected with the control unit; the control unit is electrically connected with an elevator running circuit; the simulating key panel is arranged on the inner side wall of the cage; the detection unit is a TOF photoelectric sensor and is used for acquiring a key operating signal on the simulating key panel and transmitting the key operating signal to the control unit; the control unit controls the elevator running circuit to carry out a corresponding operation. The inductive elevator operating panel has the advantages as follows: the TOF photoelectric sensor and the simulating key panel are coordinated to simulate multiple columns of operating areas on the inner side wall of the cage, so that conventional mechanical buttons can be replaced, the problem of aging of mechanical components can be avoided, mounting and debugging of the panel and wiring of the circuit are simplified and the cost is reduced; the inductive elevator operating panel is good in anti-jamming capability, is slightly affected by the environment, and is high in reliability, good in sensitivity and long in service life.

Description

technical field [0001] The invention belongs to the technical field of elevator accessories, and in particular relates to an inductive elevator operation panel. Background technique [0002] At present, passenger elevators are intelligent and automatic equipment controlled by microcomputers, and do not require special personnel to operate them. Passengers press the elevator button to reach the floor they want to reach according to their own needs. Elevator buttons are indispensable as a guide. The human-machine interface in the elevator car on the market, that is, the operation panel, basically uses a stainless steel panel, and the buttons and floor display are embedded in the mounting holes of the panel. Most of the existing elevator buttons adopt a mechanical structure, and the main component is a spring-type mechanical switch, that is, through the force of pressing the button externally, the mechanical contact is turned from the disconnected state to the closed state, a...

AI Technical Summary

Problems solved by technology

The operation panel with this structure has the following disadvantages: the mechanical buttons include button caps, return springs and contacts, etc., and there are many scattered parts, which makes the overall assembly and debugging of the operation panel with multiple buttons more cumbersome; With the passage of time or the influence of adverse environment, mechanical buttons will inevitably have problems such as spring aging and deformation of mechanical parts, resulting in a decrease in reliability and affecting the normal use of the elevator; because the button switch of the traditional elevator operation panel needs to be formed mechanically, it is waterproof The dust-proof effect is unsatisfactory; the buttons are not resistant to external shocks and are easily damaged; the cost is high, usually the price of an
