SOLUTION: At least one of the failure information pieces emitted by a control board 2 in the event of failure occurrence is given on a display 6, while the other pieces of failure information are given in the display one after another by pushing a call button 7 for registering car calls installed at the reference floor 4 or pushing the call button 7 to register a car call and also operating a key switch 5 to put the elevator operation in pause.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator failure information display device for displaying elevator failure information.

[0002]

2. Description of the Related Art Conventionally, an elevator controlled using a microcomputer (hereinafter referred to as a microcomputer) concentrates each signal of the elevator in an elevator machine room as disclosed in Japanese Patent Application Laid-Open No. 51-10844. When a failure occurs, a maintenance person can know the state of the failure by looking at the lighting state of the indicator lamp of the display device.

When a failure occurs in an elevator, a manager of the building notifies the maintenance center that the failure has occurred. Therefore, a maintenance worker working near the place where the failure has occurred goes to the elevator machine room of the building for restoration, and performs restoration work of the elevator using the display device.

[0004] Therefore, since the maintenance staff does not know the detailed state of the failure of the elevator until he or she goes to the elevator machine room, the maintenance is restored without any prior knowledge, and the tools required for repair and the analysis required for failure analysis are required. In addition to taking a long time due to insufficient preparation of instruments etc.,
In some cases, a maintenance person who is not suitable for this failure recovery is dispatched, which has been a problem. In order to solve this problem, Japanese Patent Laid-Open Publication No. Hei 2-182682 discloses that when a failure occurs in an elevator, the failure diagnosis device stops the door with the door closed, and it is understood that passengers are trapped in the car. The result of the failure diagnosis is converted into character information via the conversion device and displayed on the display device as, for example, "The door has not been opened and several people have been locked in the car due to the failure of the door."

Therefore, the failure information is communicated to a maintenance center by a passer-by of the hall or by an administrator when the display device is seen, and the details of the failure are communicated to a maintenance person who is suitable for the repair. Since a maintenance tool and an instrument suitable for repair can be brought, it is possible to quickly restore a failed elevator.

[0006]

In the prior art, when a failure occurs in an elevator, a failure diagnosis is performed by a failure diagnosis device in the elevator machine room, and the result is transmitted to a reference floor elevator hall via a character conversion device. Although displayed on the provided display device, the fault diagnosis device, the character conversion device, and the display device provided at the elevator hall on the first floor must not be installed as standard equipment in the elevator, but must be newly installed. There is a problem that the cost must be increased.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and has as its object to normally use an existing display for displaying the position of a car and to easily provide fault information simply by changing the software to an existing elevator. It is to provide a device capable of displaying.

[0008]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a control panel which performs control using a microcomputer and outputs a plurality of pieces of fault information, and a control panel which is installed at least on a reference floor among landings on each floor. Connected via a signal line and having a display unit for displaying the position of the car at normal times, at least one of a plurality of pieces of failure information output from the control panel at the time of occurrence of the failure is displayed on the display unit. This is achieved by a configuration in which display is performed and other failure information is sequentially displayed on the display unit in response to operation of hall equipment installed on the reference floor.

BRIEF DESCRIPTION OF THE DRAWINGS FIG.
This will be described with reference to FIG.

FIG. 1 is an overall configuration diagram of an elevator failure information display device according to the present invention, FIG. 2 is a flowchart at the time of occurrence of a failure, and FIGS. 3 and 4 show display examples of displaying failure information on the failure display device. FIG.

In these figures, FIG. 1 shows a control panel 2 provided in a machine room 1 of an elevator, a display section 6 provided at a landing on a reference floor, and a key switch 5 for stopping the operation of the elevator. It is connected to a control panel 2 in a machine room 1 of the elevator via a cable 3 which is a wire.

Next, the operation of the elevator failure information display device according to the present invention will be described.

First, in step 1 of FIG. 2, it is determined whether or not the elevator is out of order by the control panel 2. If not, the car position is displayed on the fault display device 6 as in step 5. If it is determined that a failure has occurred, the failure display 6 shown in FIG.
Display trouble information as shown. In addition, the display example of the failure display device of FIG. 3 is displayed as A1, and displays failure information at the time of failure. Next, when the maintenance person arrives at the failed building and operates the call button 7 for registering the call of the hall 4 as in step 3 or the call button 7 for registering the call and the key switch 5 for stopping the elevator, 4, failure information is sequentially displayed as indicated by 10, 11, 12, and 13 in FIG. It is a code number indicating that a trouble has occurred in the door “A1” in FIGS. 8 and 9 and it can be understood that a trouble has occurred in the door, and “5” in FIG. The floor, the number of failures, and the state of the elevator at the time of failure can be known from "2" of 11, "1", and "F" of 12.

Therefore, when a failure occurs, the code numbers shown in FIG. 3 among the plurality of failure information output from the control panel 1 are displayed on the display units 8 and 9 so that the failure content can be obtained without going to the elevator machine room. From the control panel 1 by operating the call button 7 for registering a call, or the call button 7 for registering a call and the key switch 5 for suspending the operation of the elevator, which are installed on the reference floor 4. By sequentially displaying the plurality of output failure information on the display unit, the floor of the elevator, the number of failures, the state at the time of failure can be confirmed, and the existing display for displaying the car position at normal time is used, so that the existing display is used. The fault information can be easily confirmed simply by changing the software of the elevator to the elevator, and the failed elevator can be quickly restored. Further, by displaying the failure information by two operations of the call button 7 for registering the call and the key switch 5 for suspending the operation of the elevator, misuse of a third party can be prevented.

[0015]

According to the present invention, it is possible to easily display failure information by using an existing display for displaying the position of a car at normal times and simply changing the software to an existing elevator.
