Abstract

PURPOSE:To make display of the failed condition in which the part of failure can be given expressly and detailedly without addition of any indicator lamp. CONSTITUTION:In the event of failure, a relay to sense failure is actuated, and hall call buttons U, D are selected and pushed, and thereby car position indicator lamps L1, L2 to which the part of failure is in advance divided and allocated, are lighted up with relay contacts 1X1-2Z1 which are actuated at failure, and the failed condition is displayed. Thereby a number of parts of failure can be displayed with a lesser number of car position indicator lamps.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator failure status display apparatus, and more particularly to an elevator failure status display apparatus suitable for restoration and maintenance inspection of failures.

[0002]

2. Description of the Related Art As a prior art of a failure status display device for an elevator, as described in JP-A-58-89571, an existing car position display device is operated in a mode different from normal in the event of a failure or disaster. There was a technology to notify by that.

[0003]

By the way, in the above-mentioned prior art, in the case of an elevator servicing a low floor, since the number of indicator lights of the car position display device is small, it is necessary to limit the number of failure display points, and to service the high floor. Even in the case of elevators, all the failure states are displayed without being classified, and there is a problem that it is difficult to determine the failure state, and it cannot be said that the display means is sufficient when the maintenance personnel recover from the failure.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator failure status display device capable of determining a failed part earlier without limiting the number of failure status display points for an elevator servicing a lower floor. It is in.

[0005]

The above object is to provide a failure state of an elevator having detection means for checking the operating state of each device for controlling the elevator to detect a failure, and display means for displaying the failure by the detection means. In the display device, while dividing the elevator failure part into multiple,
The display of these failed parts is achieved by providing a function of selecting the failed part on a plurality of hall call buttons installed at the hall.

[0006]

According to the present invention, when the failure state is displayed, the failure portion can be selected and displayed. Therefore, it is possible to quickly determine the failure portion, and it is necessary to limit the display points of the failure state even in an elevator servicing a low floor. Since there is not, it is possible to determine a detailed failure point.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of an elevator failure status display device of the present invention will be described below with reference to the drawings. FIG. 1 is an electric circuit diagram showing an embodiment of an elevator fault status display device according to the present invention.

In FIG. 1, U is an elevator hall upward call button for an arbitrary floor, D is an elevator hall downward call button for an arbitrary floor, and T ₁ and T ₂ are relays (not shown) that are activated when a failure is detected. A transfer contact, A is a relay that is activated when the call button U is pressed during a failure, A _{1 to} A ₃ are normally open contacts of the relay A, and B is a relay that is activated when the call button D is pressed during a failure. , B _{1 to} B ₃ are normally open contacts of the relay B, C is a relay that is energized by pressing the call buttons U and D at the same time, and C _{1 to} C ₂ are transfer contacts of the relay C. Also L1 and L2
Shows an indicator light for displaying the car position of each different arbitrary floor. 1X ₁ , 2X ₁ , 1Y ₁ , 2Y ₁ , 1Z ₁ , 2Z ₁
Is a contact point of a relay that detects different failure states of previously divided parts, and 1X1 is _one of a plurality of divided failure parts, which is a relay (not shown) that is activated when a certain safety device operates. A normally open contact, 2X _1, is a normally open contact of a relay (not shown) which is activated when a safety device different from the safety device in the same division as the one division operates. Further, 1Y ₁ and 2Y ₁ are different from the above-mentioned 1 section, and are normally open contacts of a relay (not shown) which are energized when different devices involved in opening and closing the door fail. Similarly, 1Z ₁ and 2Z ₁ are normally open contacts of a relay (not shown) that are activated when a power failure occurs in each circuit in a section different from the above section.

Next, the operation of this embodiment will be described. When a failure occurs in the elevator, the failure detection relay T is activated and T
_The hall call cannot be registered due to the normally closed contacts of ₁ and T ₂ . On the other hand, when the hall upward call button U is pressed in this state, the relay A is energized. Similarly, when the down hall call button D is pressed at the time of failure, the relay B is activated, and when the hall call buttons U and D are simultaneously pressed, the relay C is activated. Now, one as failure case, when the relay 1X when there safety device has operated is energized by pressing a landing on direction Kobotan U, 1X ₁ -A ₂ -C ₁ because the relay A is energized -A closed circuit of L1 is formed and the indicator lamp L1 is turned on. As a result, it is immediately known that the safety device previously assigned to the indicator light L1 is operating. On the other hand, at this time, if the hall down call button D or the up call button U and the down call button D are pushed at the same time, the closed circuit of the indicator lamp is not formed, so that L1 does not light. Another example of failure is relay 1Z when a certain power supply becomes abnormal.
If the upper direction call button U and the lower direction call button D are pressed at the same time, the relay C is activated, so that the closed circuit of 1Z ₁ -C ₁ -L ₁ is formed and the indicator lamp L 1 is formed. Lights up. At this time, the same L as when the safety device operates
Although 1 is lit, since the landing call button pressed is different, it is possible to immediately determine where the failure site is.

Further, even if six display points are required for the failure state, two display lamps are sufficient according to the present embodiment. Therefore, the addition of the display lamps is particularly necessary for an elevator servicing a low floor. The failure state can be displayed in detail without reducing the display lighting. Furthermore, if the present embodiment is applied to maintenance and inspection and the failure detection relay T is energized by the inspection switch, the elevator can be easily inspected.

[0011]

According to the present invention, when a failure condition is displayed, it is possible to select and display the failure part, so that it is possible to quickly determine the failure part and the number of display points of the failure condition even in an elevator servicing a low floor. Since there is no need to limit the above, there is an effect that a detailed failure point can be determined.
