JPH11278765A - Car position indicator of elevator - Google Patents

Abstract

PROBLEM TO BE SOLVED: To enable a visually handicapped passenger to recognize the landing floor without bothering another person's hand, by providing a buzzer to sound in order to indicate the landing floor of a car, and a control part to output a signal to indicate the landing floor to an electronic buzzer, if information about the landing floor of the car is inputted to a car control panel. SOLUTION: A car position indicator 8 consists of one chip microcomputer 9 (control part) and an electronic buzzer 10 connected to it. The one chip microcomputer 9 is connected to a car control panel 11 to control an operation of an elevator, and information from the car control panel 11 about the landing floor of the car is inputted in it, and if the information about the landing floor of the car is inputted in the one chip microcomputer 9 from the car control panel 11, a driving signal is outputted from the one chip microcomputer 9 to the electronic buzzer 10, to sound the buzzer. For instance, if information about landing floors from the first floor to the fourth floor is inputted in the one chip microcomputer 9, an instruction to sound with a short sound as many times as the number of the landing floor is given to the electronic buzzer 10 from the one chip microcomputer 9. If its sounds three times, the landing floor is the third floor.

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a car position indicator which indicates the floor of an elevator car with a buzzer sound.

[0002]

2. Description of the Related Art Conventionally, when a passenger gets into a car arriving at a landing of an elevator and presses a destination floor button on a car operation panel, the destination floor is registered in a car control panel. A command is output from the car operation panel to driving means such as a hoist, and the car travels to the destination floor. When the car arrives at the destination floor, the floor position of the car is indicated by a number on the car position indicator in the car. The passenger recognizes the landing floor of the car by looking at the numbers displayed on the car position indicator.

[0003] By the way, in the elevator type car position display of a high-end type, there is a type that announces the floor floor by voice in addition to the number of the floor floor. Then the landing floor is simply represented by a number.

[0004]

In such a conventional general-purpose elevator car position display, an expensive announcement device is not provided, but only a floor floor is represented by a numeral. In order to recognize the floor on which a visually impaired person in a car has landed, a healthy person in the same car must teach the floor on which the floor is imposed. There was a problem that it was troublesome.

SUMMARY OF THE INVENTION It is an object of the present invention to enable a passenger on a car to recognize a landing floor without any trouble even if the passenger is visually impaired.

[0006]

According to the present invention, there is provided an electronic buzzer which sounds to indicate a floor at which a car is landing, and information which indicates that the car has landed from a car control panel. Is input to the electronic buzzer, and a control unit that outputs a signal indicating the landing floor to the electronic buzzer.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described below with reference to the drawings. 1 and 2 are views showing an embodiment of an elevator car position indicator according to the present invention.

In FIG. 1, reference numeral 1 denotes a sleeve wall of a cab of a general type elevator. The sleeve wall 1 is provided with a door open button 2, a door close button 3, and a car operation panel 4. The housing of the car operation panel 4 is integrated with the sleeve wall 1,
The car operation panel 4 has a number of destination floor buttons 5 corresponding to each floor, and a Braille plate 6 is juxtaposed next to the destination floor buttons 5.

A car position / direction indicator 7 is provided above the sleeve wall 1. The car position / direction indicator 7 indicates the traveling direction (vertical direction) of the car and the landing floor of the car by numbers. indicate. Below the car position / direction indicator 7, a car position indicator 8 is provided for the visually impaired.

As shown in FIG. 2, the car position indicator 8 is
The one-chip microcomputer 9 (control unit) includes an electronic buzzer 10 connected thereto.
A RAM, a PIO parallel, an SIO, an interrupt controller, a clock generator, and the like are built in. The one-chip microcomputer 9 and the electronic buzzer 10 are housed in the sleeve wall 1. The one-chip microcomputer 9 is connected to a car control panel 11 for controlling the operation of the elevator, and inputs information on the floor on which the car has landed from the car control panel 11. A signal is input to the car control panel 11 from a rotary encoder that detects the position and traveling direction of the car.

[0011] The information of the car landing floor from the car control panel 11 is 1
When input to the chip microcomputer 9, a drive signal is output from the one-chip microcomputer 9 to the electronic buzzer 10 and a buzzer sounds. For example, when the information on the landing floors from the first floor to the fourth floor is input to the one-chip microcomputer 9, the one-chip microcomputer 9 instructs the electronic buzzer 10 to sound the number of the landing floor in a short tone. If the electronic buzzer 10 sounds three times in a short tone, the landing floor of the car is the third floor. When the information on the fifth floor landing is input to the one-chip microcomputer 9, the one-chip microcomputer 9 instructs the electronic buzzer 10 to sound once with a long beep. Electronic buzzer 1
If 0 rang once, the landing floor of the car would be 5th floor, if it rang twice, then if it rang once, then the landing floor of the car would be 11th floor. Become.

As described above, when the car is landed, the floor on which the car is landed is represented by the buzzer sound of the electronic buzzer 10. Therefore, even if the passenger on the car is visually impaired,
The floor at the floor can be recognized without human intervention.

On the other hand, the one-chip microcomputer 9 and the electronic buzzer 10 constituting the car position indicator 8 for the visually impaired
Since both are inexpensive, the car position indicator 8 can be provided in a general type elevator without any problem in terms of cost.

[0014]

As described above, according to the present invention,
Since the control unit outputs a signal indicating the landing floor to the electronic buzzer, even if the passenger in the car is a visually impaired person, the landing floor can be recognized without any trouble.
