Description

Elevator Situation Display System

The invention relates to an elevator control system, in particular to an elevator situation display system that outputs corresponding mixed color light when corresponding to different elevator shapes.

Elevator, also known as elevator, vertical elevator, is a means of transportation that vertically transports pedestrians or goods. The specific structure of the vertical elevator mainly includes a car, which runs between at least two rows of vertical or inclination angles of less than 15 rigid guide rails. The size and structure of the car are convenient for passengers to enter and exit or load and unload goods. It is customary to use elevators as a general term for vertical transportation tools in buildings regardless of their driving methods. According to the speed, it can be divided into low-speed elevator (below 4 m/s), fast elevator (4-12 m/s) and high-speed elevator (above 12 m/s).

Generally, a modern elevator includes an inner door and an outer door. The outer door faces the outside direction, and the inner door faces the passengers in the car. When the door leaf is opened, the outer door and the inner door will be opened together for passengers to pass through. . Generally, in order to prevent the door leaf clip from hurting and carrying passengers, traditional mechanical aluminum contact pads are generally set on the door leaf of the inner door to trigger the micro switch or light blocker, and the trigger output command of these devices is used to control the door leaf. open and close. In addition, an overload indicator is generally installed on the elevator. When the elevator is overloaded, a speaker or a buzzer is used to output sound to warn the safety of passengers.

The main purpose of the present invention is to provide an elevator situation display system, which is set in coordination with the elevator, and the elevator situation display system includes at least one display light bar and a controller. The display light bar The system includes a light mixing unit and a light guide strip. The light mixing unit is aligned with the light incident portion of the light guide strip, and inputs the corresponding mixed color light according to the control signal. The controller is connected to the light mixing unit of the display light bar, and the controller outputs the control signal to the light mixing unit according to the trigger command of the input terminal, so as to control the elevator display situation.

Therefore, the present invention has the following advantageous effects:

1. The present invention can give corresponding situational effects according to the actual situation encountered by the elevator, so that passengers in the elevator can perform necessary reaction actions and appropriate human-machine interaction according to the corresponding situation.

2. The present invention gives different types of situation indications through different mixed color lights, which can not only give users a more specific feeling in the creation of situations, but also increase the aesthetics and design sense of the elevator itself. The setting can also increase the function of elevator design variability to provide safer protection for personnel and/or goods.

Wherein, the light mixing unit 11 can be a light-emitting module integrated and combined by a plurality of LED semiconductors of different colors, such as an RGB light-emitting module that simultaneously mixes red light (RED), green light (GREEN), and blue light (BLUE), The selection of these basic light sources for use in the present invention is not limited. The light guide bar 12 can be made of a light guide material, so that the light beam of a specific angle is totally reflected on the inside of the light guide bar 12 so as to light up the entire light guide bar 12 through single-end or double-end input. The light mixing unit 11 is aligned with the light incident portion of the light guide bar 12 to send the mixed color light into the inside of the light guide bar 12 .

The displays 20 are arranged on the inner side of the car 3A, and the displays 20 can be used as a man-machine interface for an operator with a specific authority to control the elevator 200, and display the situation of the elevator 200 to the elevator 200 during operation. Passengers in car 3A. The indications may be, for example, ambient light sources, specific indications (eg, text, images, images, etc.), so as to allow passengers to confirm the current state of the elevator 200 .

The controller 30 can be, for example, a general-purpose or special-purpose microprocessor (Microprocessor) programmable by a central processing unit, a digital signal processor (DSP), a programmable controller, or a special application product. Application Specific Integrated Circuits (ASIC) or other similar devices or combinations of these devices are not limited in the present invention. The controller 30 is connected to the light mixing unit 11 of the display light bar 10 and the display 20, and according to the input The trigger command of the terminal outputs the control signal to the light mixing unit 11 and the display 20, and controls the elevator 200 to display the situation according to various states of the door page.
