JPH08310752A - Failure detecting device for elevator monitor panel - Google Patents

Abstract

PURPOSE: To quickly and accurately discover a burnt-out lamp with small electric power by simultaneously lighting multiple indicator lamps, then transiently lighting all indicator lamps in sequence, and lighting an indicator lamp adjacent to a burnt-out indicator lamp. CONSTITUTION: A lamp test button 1 is connected to a lighting control circuit 2, thyristors n1 -nn are connected to signal output ports N1 -Nn provided on the lighting control circuit 2, and lamps 3-1 through 3-n installed in indicator lamps 3 are connected. When a signal is outputted from the lighting control circuit 2 to the signal output port N1 , for example, the connected thyristor n1 is turned on, and the lamp 6-1 is turned on. Multiple indicator lamps 3 are concurrently lighted in sequence. An indicator lamp adjacent to a burnt-out indicator lamp can be kept on, and the position of the burnt-out lamp can be accurately found in a short time.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a failure detecting device for an elevator monitoring board.

[0002]

2. Description of the Related Art A conventional technique for sequentially turning on indicator lights by a specific lighting command device is, for example, as disclosed in Japanese Patent Laid-Open No. 59-124662, an inspection command signal for an elevator hall indicator light. It is known to have a switch to output and turn on the indicator lights installed in the hall one by one for a predetermined period of time on condition that this survey command signal is output, and confirm that the lamp is out. There is.

[0003]

However, there are some indicator lights installed on the elevator monitor panel depending on the scale, such as several hundred indicator lights.
When turning on the indicator lights one by one, it takes a lot of time to turn on all the indicator lights, and when the indicator lights that are out of lamp are approaching Since there is no indicator light that is lit, there is a risk that the audited part may be lost and that the burned-out part cannot be confirmed accurately.

In order to solve the above problem, there is also a method of turning on all the indicator lights all at once and confirming that the lamps are out. However, when there are many indicator lights, a large power source capacity is required to turn on all of them. There was a problem saying that I had to secure.

An object of the present invention is to provide an elevator monitoring panel having a failure detection device for detecting lamp burnout quickly and accurately with low power consumption.

[0006]

In order to achieve the above object, the present invention sequentially turns on all the indicator lamps in a state in which a plurality of indicator lamps are simultaneously illuminated.

[0007]

Since a plurality of indicator lamps are constantly lit, any of the indicator lamps adjacent to the indicator lamp that is out of lamps can be in a state of being lit, and the location where the lamp is burnt becomes clear.

[0008]

An embodiment of the present invention will be described below.

FIG. 3 shows a front view of the elevator monitoring panel, and there is a display character 5 indicating the name of the elevator machine to be monitored at the upper part, and below it, a display for displaying the elevation direction and floor of the elevator. The lights 3 are sequentially arranged in the vertical direction.

On the other hand, a lamp test button 4 for activating a failure detection device for confirming lamp burnout is arranged at the lower right end in the figure.

FIG. 1 shows the construction of a failure detection device for an elevator monitoring board according to the present invention. Lamp test button 1
Are connected to the lighting control circuit 2, and N1, N2, N3, N
4, N5, N6 and Nn are signal output ports provided in the lighting control circuit 2 and are respectively provided in the thyristors n1, n2 and n.
3, n4, n5, n6 and nn are connected, and then FIG.
Lamps 6-1, 6- installed inside the indicator light 3 in the inside
2, 6-3, 6-4, 6-5, 6-6, 6-n are connected.

In the above, from the lighting control circuit 2, for example, N
When a signal is output to the port No. 1, the connected thyristor n1 is turned on and the lamp 6-1 is turned on.

FIG. 2 is a flow chart showing a signal output control procedure of the lighting control circuit 2. In FIG. 6, when confirming that the lamp test button 1 is pressed in 6, the signal output port is initialized in 7 and then a signal is output to each signal output port set in 8. As shown in the figure, the signal output processing of 8 is performed by adding the setting values A to E by 10 at a time until the value of the setting value A of the output port matches the port number of the last indicator at 9 Repeat the output.
That is, while continuously outputting five consecutive signals, the position 1 of the signal output port is updated one by one.

In the above configuration, when the signal output ports are arranged in the downward direction from the uppermost indicator lamp on the right side of FIG. Five indicator lights are turned on from the end downward, and the first indicator light from the upper right end is turned off in the second processing.
The 4th, 5th and 6th indicator lights are lit. Therefore, when the main lighting operation is repeated and a lamp that does not light up is approached, only the defective lamp does not light up while five consecutive lighting displays pass, so that the position can be clearly confirmed and the possibility of overlooking is reduced. .

According to the embodiment, since a plurality of indicator lamps are sequentially turned on at the same time, adjacent to the indicator lamps that are out of lamp,
Since either of the indicator lamps can be turned on, it is possible to accurately detect the lamp burnout portion in a short time with a small amount of power.

[0016]

[Effects of the Invention] By sequentially displaying a plurality of indicator lights at the same time, it is possible to reduce the electric capacity used for the lamp burnout confirmation display, and to accurately find the burned out spot in a short time. it can.
