Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a control device for an elevator for blind people that provides safe elevator operation for blind people.

[Conventional technology]

FIG. 5 is a diagram showing a conventional automatic operation device for an elevator for blind people, as disclosed in, for example, Japanese Utility Model Application Publication No. 60-142272. 3 is a platform call command to call the car to the platform where a blind passenger is waiting; 4 is a command to drive up each floor; 5 is an automatic broadcast command to notify the driving direction and arrival; 6 is a control device that generates the instructions 3, 4.5 for driving for blind persons.

Next, the operation will be explained with reference to the flowchart shown in FIG. When the blind person detection device 1 detects the presence of a blind person waiting in step 7, the process goes to step 8 and the control device 6 detects that a blind person is waiting.
A platform call command 3 is issued to automatically run the car to the platform where the blind person is waiting.

In step 9, the elevator lands at the landing and the doors are opened. Next, in step 10, the control device 6 issues an automatic broadcast command 5.
When the in-car passenger detection device 2 detects that a waiting passenger has boarded the car in step 11, the control device 6 issues each floor stopping operation command and performs each floor stopping operation in step 12. .

Next, when the car arrives at the destination floor, in step 13 the control device 6 issues an automatic broadcast command 5 for the arrival floor and performs automatic broadcast.

Next, in step 14, if there are any passengers in the car, the process returns to step 12, and if there are no passengers, the process proceeds to step 15, and normal operation is resumed.

In this way, the control device in each case informs the blind person of the arrival of the elevator and the driving direction! At t6, an automatic broadcast command 5 is issued to provide necessary information when a blind person uses the elevator.

[Problem that the invention seeks to solve]

Conventional control devices for elevators for blind people perform the operation for blind people as described above, but blind people cannot visually confirm the misalignment of the car when getting on or off the elevator. Therefore,
Even the slightest misalignment is dangerous, but no special safety measures were taken to prevent this.

This invention was made to solve the above-mentioned problems, and an object thereof is to provide a control device for an elevator for blind people that can be used safely by blind people.

[Means for solving problems]

The control device for an elevator for the blind according to the present invention detects a landing error using a landing error detection device when the elevator is operated for a blind person, and does not open the door unless the detected value is within an allowable range set for the blind person. , a means is provided for performing bed re-alignment operation.

[Effect]

In this invention, when an elevator is operated for a blind person, a landing error detection device detects a landing error, and unless the error is within an allowable range, the elevator door does not open, and a means for re-aligning the floor is used to detect the landing error. Open the door after adjusting to the permissible range set for blind people.

〔Example〕

An embodiment of the control device for an elevator for the blind according to the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing one embodiment of the same, and the same or corresponding parts as in FIG. We will mainly describe the parts that differ from the diagram.

In FIG. 1, reference numeral 18 denotes a landing error detection device installed on each floor, which is connected to the control device 6 and is a device for detecting a deviation between the landing and the car floor. Further, the control device 6 outputs a door closing and re-alignment command 19 based on input from the landing error detection device 18.

Figure 2 shows a Braille board equipped with a blind person detection mechanism.
218.21b is a Braille board that provides information in Braille to facilitate elevator use, and 218.21b is a Braille board with a built-in touch switch.

Further, FIG. 3 shows an embodiment of a sequence circuit that controls the operation of the blind person detection device 1 shown in FIG. 1. In FIG. 3, (+) and (-) are power supplies 22a.

Reference numeral 22b indicates a touch switch built into each of the Braille characters 21a and 21b, 23 indicates an off-timer which operates immediately when energized, and maintains a predetermined period of time even when de-energized, and 23a indicates a normally open contact of the off-timer 23.

A touch switch 22a and an off timer 23 are connected in series between power supplies (+) and (-), and a touch switch 22b
The normally open contact 23a and the blind person detection device 1 are connected in series.

Next, the operation will be explained with reference to the flowchart shown in FIG.

When a blind person attempts to use an elevator, when he reads the Braille characters 21a on a Braille board 20 installed at the platform with his finger, a touch switch 22a is turned on.

This energizes the off-timer 23 and closes its normally open contact 23a. When the finger is removed from the touch switch 22a, the off timer 23 is deactivated, but if the holding time of the off timer 23 is set longer than the standard time for a blind person to read Braille, then the touch switch 22a is turned off.
When b is touched, the power supply (+) - touch switch 22b - normally open contact 23a - blind person detection device 1 - (-) power supply circuit is turned on, the blind person detection device 1 operates, and the elevator performs blind operation. . (Step Sl) Here, if the touch switch 22b is not touched even after a predetermined period of time has elapsed after touching the touch switch 22a, the normally open contact 23a returns to its initial state to prevent false detection.

When a blind person is detected by the blind person detection device 1 as described above, the control device 6 issues a platform call command 3, and step S
In step 2, automatic registration of the lift and descent of the platform call is performed, and the car is automatically called to the platform where the blind person is waiting. When the car arrives in step S3, the landing error detection device 18 detects the deviation between the floor of the car and the end of the landing area in step S4, and determines whether the landing error is within an allowable range set for blind people. If the deviation is not within the allowable range, the process goes to step S5, and the floor alignment operation is performed again without opening the door, and after the deviation is within the allowable range, step S6
Then, the automatic broadcasting command 5 is issued from the control device 6, and automatic broadcasting is performed.

In step S7, the in-car passenger detection device 2 detects that a blind person has entered the car, and in step S8, blind person driving is performed according to each blocking driving command 4. When arriving at the next floor in step S9, if the landing error is not within the allowable range in step 310 as described above, the floor alignment operation is performed again in step Sll, and after the landing error is within the allowable range, the process proceeds to step S12. The door opens to announce the arrival of the basket. Then, in step S13, the operation for blind persons is performed until there is no blind person in the car.

When there is no blind person in the car, the process advances to step 314 and normal operation is resumed.

〔Effect of the invention〕

As explained above, this invention does not open the door unless the landing error is within an allowable range during operation for the blind, and automatically broadcasts the arrival of the car after re-aligning the floor, thereby particularly improving the landing accuracy. This makes it possible to provide a device that allows blind people to get on and off more safely without reducing the utilization efficiency during normal operation.
