Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator overpass guide device for guiding overpassing of an elevator car.

[0002]

2. Description of the Related Art Recently, there has been an increase in the number of elevators in which passengers are informed by voice of an overriding state. Voice guidance is effective because it can reliably convey the driving state to passengers, but it requires some time to completely convey the information. Also, if the voice is stopped halfway, information cannot be transmitted. Therefore, the weighing device that detects the load of the car changes in a short time and the guidance is continued even if the overriding state is resolved,
There is a problem that information cannot be accurately transmitted, such as giving guidance to passengers even if the elevator door is already closed or while opening and closing the door, and giving distrust to passengers.

In order to improve the accuracy of the weighing device, there is a conventional method for detecting overdriving only when the weighing device is continuously operated for a predetermined time, as described in JP-A-63-306181.

[0004]

In the above-mentioned prior art, the certainty of detection of the weighing device is improved, but guidance for passengers is not taken into consideration, and overload is detected only when the weighing device is continuously operated for a predetermined time. The method has a problem that the guidance is delayed. Also, neither the open / closed state of the door nor the timing of overpass guidance is taken into consideration.

It is an object of the present invention to accurately and swiftly inform an passenger of an elevator car overrun.

[0006]

SUMMARY OF THE INVENTION The above-mentioned object is to provide an overload detection means for detecting an overload in a car and an overload detection signal detected by the overload detection means to give an audible and / or warning to a passenger. In an elevator overpass guidance device having an overload guide means for guiding by sound and an elevator car door open detection means for detecting that the door of the elevator car is open, the overpass detection signal and the elevator car door are provided. This is achieved by providing a means for inputting an open detection signal to the car door output by the open detection means and outputting an overpass guide command to the overload guide means.

[0007] The above object is to provide an overload detecting means for detecting an overload in a car and an overload guide for guiding an overpass to a passenger by a voice and an alarm sound by an overload detection signal detected by the overload detecting means. Means and a car door open detection device for detecting that the door of the car is open, in an overpass guide device for an elevator, a vehicle output by the overcarriage detection signal and the car door open detection device. This is achieved by providing a delay means for inputting an opening detection signal to the car door and delaying the overload guidance command by voice to the overload guidance means for a predetermined time.

The above-mentioned object is to provide an overload detecting means for detecting an overload in a car and an overload guide for guiding an overpass to a passenger by a voice and an alarm sound by an overload detection signal detected by the overload detecting means. Means and a car door open detection device for detecting that the door of the car is open, in an overpass guide device for an elevator, a vehicle output by the overcarriage detection signal and the car door open detection device. A means for inputting an opening detection signal to the car door and outputting an overriding guidance command by an alarm sound to the overload guiding means, and a car door output by the overriding detection signal and the riding car door opening detection means Is provided by inputting the open detection signal and delaying means for delaying the overload guidance command by voice to the overload guidance means for a predetermined time.

[0009]

According to the above structure, since all overpass guidance is performed only when the door is fully opened, the door is not yet open when the weighing device operates for a short time due to a shock when the elevator is stopped. Therefore, we do not provide overboard guidance.

Further, when the door is fully opened, the vibration at the time of stoppage has subsided, and the weighing device does not operate unless passengers get in, and erroneous overpass guidance is not provided.

If the weighing device is operated for a short time due to a shock when a passenger gets into the elevator, the door is fully opened and the overpass guidance is given. Passengers do not get the impression that they have malfunctioned because they do not provide voice guidance alone.

When an excessive overriding occurs, guidance is immediately given with a warning sound, and voice guidance is provided after a predetermined time has passed, so that guidance is not delayed.

In this way, overriding of the elevator car can be accurately and promptly transmitted to passengers.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a sequence circuit diagram for explaining the configuration of the embodiment of the present invention.

First, the configuration of this embodiment will be described.

As shown in the figure, each control element and a contact are connected between the control power supplies P and N.

WD1 is a normally open contact (a contact) which is closed when the weighing device for detecting the load of the elevator car exceeds the limit load. The WDA is a scale device operation detection relay in which WD1 is closed and excited when overload of the scale device is detected, and has normally open contacts WDA1, WDA2, WDA3. DOP
1 and DOP2 are basically normally open contacts of a door opening completion detection relay (coil omitted) which is provided for controlling the motor to stop when the door opening is completed. BZ is a buzzer for overpass guidance that provides overpass guidance with an alarm sound, and WDAT is a timer that delays the start of voice guidance and has a normally open contact WDAT1. AU has a built-in ROM
This is a voice guidance device for performing overpass guidance by voice from a voice guidance speaker SP according to a guidance message stored in. The door opening command outputs a command for opening the door that prompts the passenger to exit due to the detection of the overload of the weighing device.

Next, the operation of this embodiment will be described.

When a weighing device (not shown) is operated with the door open, the buzzer BZ sounds and the buzzer BZ is activated for a predetermined time (usually 2.
It shows the case where the overpass guidance is given by voice after about a second).

When the normally open contact WD1 of the weighing device is closed, the weighing device operation detection relay WDA is excited by P-WD1-WDA-N. Even if the weighing device operation detection relay WDA is excited, if the door is not fully opened, the normally open contacts DOP1 and DOP2 of the door opening completion detection relay (coil omitted) are open. The guidance start time limit timer WDAT is not turned on, and incorrect guidance is not given to malfunction of the weighing device due to vibration such as when the elevator stops.

Since the normally open contacts DOP1 and DOP2 of the door opening completion detection relay are closed when the door is fully opened, if the normally open contact WD1 of the weighing device is closed, P-WD
Buzzer BZ for overpassing with A1-DOP1-BZ-N
Sounds immediately. In addition, P-WDA2-DOP2-W
In the DTA-N, the voice guidance start time limit timer WDAT operates and starts counting. After a lapse of a predetermined time, the normally open contact WDAT1 of the voice guidance start time timer is closed, the voice guidance device AU is activated, and the voice guidance speaker SP performs overpass guidance by voice.

As a result, since the buzzer BZ for overriding guidance sounds only for the malfunction of the weighing device due to the vibration when the passenger gets in the passenger, the passenger does not feel distrustful and the passenger does not override the vehicle properly. Even if it is detected, the over-guidance buzzer BZ sounds, and the over-guidance guidance is performed by voice, so that there is no delay in the guidance.

With respect to the opening of the door when the vehicle is overloaded, since the door opening command circuit (detailed circuit is omitted) is activated by the normally open contact WDA3 of the weighing device operation detection relay, no delay occurs.

According to this embodiment, erroneous overpass guidance can be prevented and the passengers will not feel distrust when the weighing device malfunctions due to vibration when the elevator is stopped or when the elevator is on board.

Although this embodiment is shown as a wired logic circuit, a TTL element such as a gate IC or a timer I is used.
It goes without saying that it can be realized by using a logic circuit using C or a microcomputer that performs the above control by a program.

[0027]

According to the present invention, since all overpass guidance is performed only when the door is fully opened, erroneous guidance is prevented, and the override of the elevator car is accurately and promptly transmitted to passengers. Is obtained.
