Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator failure state display device, and more particularly to an elevator failure state display device suitable for recovering from a failure.

[0002]

2. Description of the Related Art In recent years, elevators have been installed in machine rooms to check the operating state of each device for controlling the elevators and to detect failures, storage means for storing failure information detected by the detection means, An elevator failure state display device having display means for displaying failure information is provided.

[0003] When a failure occurs, the elevator maintenance worker checks the failure information displayed on the display means to identify the failure site and perform a recovery operation.

[0004] However, since the machine room is installed on the roof of a building, it is necessary to go to the roof by stairs in order to identify a faulty part, which places a heavy burden on maintenance personnel.

Therefore, conventionally, there has been proposed an apparatus which displays the failure information on a car position display device provided at a landing to reduce the burden.

An example of this kind of technology is disclosed in
The disclosure is found in Japanese Patent Application Laid-Open No. 0-61482 and Japanese Patent Application Laid-Open No. 6-329364.

[0007]

However, even in the above-mentioned prior art, there is a disadvantage that the failure site cannot be specified accurately and the user must go to the machine room.

That is, it is difficult to display all of the failure information because there are about 100 types of failure information, and even if it can be displayed, only one type of failure information can be displayed. However, there is an inconvenience that it is not possible to accurately identify the failure site when the problem is involved.

The present invention has been made in view of the above-mentioned inconvenience, and an object of the present invention is to provide a failure state display device for an elevator which can accurately specify a failure site at a landing without going to a machine room.

[0010]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention is provided in a machine room and checks operating states of each device for controlling an elevator to detect a failure, and detects the failure by the detecting means. In the elevator failure state display device having storage means for storing the failure information and display means for displaying the failure information, a reference terminal, or a connection terminal provided at the landing of the floor near the reference floor,
A signal line wired to connect the connection terminal and the storage unit, and a reading unit connected to the connection terminal and reading and displaying the failure information stored in the storage unit via the signal line; It is characterized by comprising.

According to the present invention, since the failure state display device is constructed as described above, if the reading means is connected to the connection terminal provided at the landing on the reference floor or the floor near the reference floor, it is stored in the storage means of the machine room via the signal line. Since direct access is possible, it is also possible to sequentially read out all failure information, and it is possible to accurately identify a failure part.

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

FIG. 1 is an overall configuration diagram of an elevator failure state display apparatus according to an embodiment of the present invention.

First, an overall configuration of an elevator to which the failure state display device according to the present invention is applied will be described.

In FIG. 1, a control panel 1 is provided in an elevator machine room 14.

The control panel 1 includes a detecting means 4 for checking the operating state of each device for controlling the elevator and detecting a failure, a display means 5 for displaying failure information detected by the detecting means 4, It comprises a storage means 6 for storing information and a control device 2 for controlling the travel of the elevator based on the information from the detection means 4.

The control device 2 and the detecting means 4, the display means 5, and the storage means 6 are connected to each other by a flat cable 3.
Connected by

The landing 10 is provided on a reference floor where the entrance and the like of the building are provided and the number of users is the largest, and includes a hatch door 9 and a car position display device 8.

Next, the configuration of the failure state display device of the present invention will be described.

The failure state display device according to the present invention comprises a connection terminal 1 provided near a push button 11 of the reference floor 10.
5, a signal line 7 connecting the connection terminal 15 to the storage means 6, a connection line 12 connected to the connection terminal 15 at one end, and a portable line connected to the other end of the connection line 12. And a reading means 16 including a personal computer 13.

The operation will be described by taking as an example a case where a door switch (not shown) of the hatch door 9 on the reference floor is not turned on.

The maintenance person dispatched due to the occurrence of the failure first connects the portable personal computer 13 as the reading means 16 to the connection line 12.
Is connected to the connection terminal 15.

By performing a predetermined operation on the portable personal computer 13, the failure information is read out from the storage means 6 via the signal line 7 and displayed on the monitor 13a.

Then, the hatch door 9 is provided on the monitor 13a.
Is displayed, indicating that the door switch (not shown) is not operating.

In this case, since it is not known which floor door switch has not been operated yet, the maintenance staff accesses the storage means 6 again using the portable personal computer 13 and stores the failure information on the hatch door of the storage means 6. The hatch door information of each floor is sequentially read from the area to be displayed and displayed on the monitor 13a.

By doing so, the hatch door 9 on the reference floor
If it is determined that the failure has occurred, the repair work is completed by inspecting and repairing the door switch.

As described above, according to the present invention, since it is possible to directly access the storage means 6 of the machine room 14 from the reference floor 10 and read out the fault information necessary for specifying the faulty part, the time required to go to the machine room is reduced. And labor can be greatly reduced.

In this embodiment, the push button 11 of the reference floor is used.
Is provided in the vicinity of the reference floor, but if the connection terminal is restricted by a problem such as design, the same effect can be obtained by providing the connection terminal in the vicinity of the reference floor.

[0029]

As described above, according to the present invention, since the fault state display device is configured, it is possible to accurately specify a faulty portion and quickly perform repair and recovery without going to the machine room.
