DETAILED DESCRIPTION OF THE INVENTION

[0001]

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

[0002]

2. Description of the Related Art Recently, elevators of a type that guides passengers to an overriding state by voice are increasing. Guidance by voice is effective in reliably transmitting the driving state to the passenger, but it requires a certain amount of time to completely transmit the information. In addition, information cannot be transmitted if audio is stopped halfway. For this reason, the weighing device that detects the load on the car changes in a short time and the guidance continues even though the overriding condition has been resolved,
There is a problem that information cannot be transmitted accurately, for example, guidance is given even when the door of the elevator is already closed, or the door is being opened and closed, giving a passenger distrust.

In order to improve the accuracy of the weighing device, there has been a method of detecting overload only when the weighing device has continued for a predetermined time as disclosed in Japanese Patent Application Laid-Open No. 63-306181.

[0004]

In the above prior art, the reliability of detection of the weighing device is improved, but guidance for passengers is not taken into consideration, and overloading is detected only when the weighing device has continued for a predetermined time. In the method, there is a problem that guidance is delayed. Also, the open / closed state of the door and the timing of the overriding guidance are not considered.

[0005] It is an object of the present invention to accurately and quickly transmit overload of an elevator car to passengers.

SUMMARY OF THE INVENTION It is an object of the present invention to provide an overload detecting means for detecting an overload in a car, and a voice and / or alarm for overloading a passenger based on an overload detection signal detected by the overload detecting means. In an elevator overshoot guide device having overload guide means for guiding by sound and car door open detection means for detecting that the door of the car is open, the overload detection signal and the car door This is achieved by providing means for inputting an open detection signal to the door of the car output from the open detecting means and outputting an overriding guide command to the overload guide means.

An object of the present invention is to provide an overload detecting means for detecting an overload in a car, and an overload guide for guiding a passenger by voice and an alarm sound based on an overload detection signal detected by the overload detecting means. Means, and a car door opening detecting means for detecting that the car door is open, wherein the car getting over detecting signal and the car door opening detecting means output. This is achieved by providing a delay means for inputting an open detection signal to the car door and delaying the overload guidance means by voice to the overload guidance means for a predetermined time.

An object of the present invention is to provide an overload detecting means for detecting an overload in a car, and an overload guide for guiding the passenger to the overload by voice and warning sound based on the overload detection signal detected by the overload detecting means. Means, and a car door opening detecting means for detecting that the car door is open, wherein the car getting over detecting signal and the car door opening detecting means output. Means for inputting an open detection signal to the car door and outputting an overshooting guidance command by an alarm sound to the overload guidance means; and a car door output by the overshooting detection signal and the car door open detection means. Is provided by providing a delay means for inputting an open detection signal and delaying the overload guidance command by voice to the overload guidance means for a predetermined time.

[0009]

According to the above arrangement, all overriding guidance is performed only when the door is fully opened. Therefore, if the weighing device operates for a short time due to a shock when the elevator stops, the door is not yet opened. So do not give too much guidance.

At the time when the door is completely opened, the vibration at the time of stoppage has stopped, and the weighing device does not operate unless a passenger gets on the vehicle, so that erroneous overriding guidance is not performed.

When 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, so that the guide for overriding is provided. Since only voice guidance is not provided, passengers are not strongly impressed by malfunction.

[0012] When the vehicle is overridden properly, guidance by an alarm sound is immediately performed, and after a predetermined time has elapsed, guidance by voice is performed, so that guidance is not delayed.

[0013] In this way, over-ride of the elevator car can be accurately and promptly transmitted to the passenger.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS One 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 FIG. 1, control elements and contacts are connected between control power supplies P and N.

WD1 is a normally open contact (a contact) which closes when the weighing device for detecting the load of the elevator car exceeds the limit load. WDA is a weighing device operation detection relay that is excited by closing WD1 by detecting overload of the weighing device, and has normally open contacts WDA1, WDA2, and WDA3. DOP
1. DOP2 is a normally open contact of a door open completion detecting relay (coil omitted) basically provided for controlling the motor to stop when the door is opened. BZ is a buzzer for overpass guidance that provides overpass guidance by an alarm sound, and WDAT is a timer that delays the start of voice guidance and has a normally open contact WDAT1. AU is built-in ROM
Is a voice guidance device that performs overboard guidance by voice from the voice guidance speaker SP based on the guidance message stored in the voice guidance speaker SP. The door opening command outputs a command to open a door for urging a passenger to exit by detecting an 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 is sounded for a predetermined time (usually 2 hours).
(About seconds), a case in which excessive guidance is provided by voice.

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 energized, 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, so that the buzzer BZ for overriding guidance and the sound The guidance start time limit timer WDAT is not turned on, and erroneous guidance is not provided for a malfunction of the weighing device due to vibrations such as when the elevator stops.

When the door is completely opened, the normally open contacts DOP1 and DOP2 of the door open completion detecting relay are closed. Therefore, when the normally open contact WD1 of the weighing device is closed, P-WD is closed.
Buzzer BZ for overriding guidance with A1-DOP1-BZ-N
Sounds immediately. Also, P-WDA2-DOP2-W
In 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 timed timer is closed, the voice guidance device AU is activated, and the voice guidance speaker SP performs overpass guidance by voice.

As a result, the overshooting guide buzzer BZ sounds only when the weighing apparatus malfunctions due to vibrations when the passenger gets on the vehicle. Even when the detection is detected, the overshooting guidance by voice is performed following the sound of the overshooting guidance buzzer BZ, so that there is no delay in the guidance.

Regarding the opening of the door when the vehicle is overridden, the normally open contact WDA3 of the weighing device operation detection relay activates the door opening command circuit (detailed circuit omitted), so that no delay occurs.

According to the present embodiment, when the weighing device malfunctions due to vibrations when the elevator stops or gets in, mistaken overriding guidance can be prevented, and the passengers will not be distrusted.

Although the present embodiment is shown by a wired logic circuit, TTL elements such as a gate IC and a timer I
Needless to say, the present invention can also 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, erroneous guidance is prevented because all overriding guidance is performed only when the door is fully opened, and the effect of accurately and quickly transmitting the overriding of the elevator car to the passenger can be obtained. Is obtained.
