Abstract

PURPOSE:To suppress a power supply unit from increasing its capacity for lighting a boarding place display device while suppressing an increase of the display device total unit in its electric load by shifting the timing of clicker- lighting each floor display appliance so as to be prevented from overlapping with each other. CONSTITUTION:Each of the first, second and the third flicker relays generates a flicker signal so as to be prevented from overlapping with each other, respectively flickering display devices 1FL-3FL in the first-third floors by a normally-opened contact 4a of the first flicker relay, display devices 4FL-6FL in the fourth-sixth floors by a normally-opened contact 6a of the second flicker relay and display devices 7FL-9FL in the seventh-ninth floors by a normally- opened contact 8a of the third flicker relay. Consequently, since a flow of current in each floor display appliance is dispersed, the electric current is prevented from its concentration, and a boarding place display device-lighting power source 13 reduces its load enabling the capacity to be prevented from increasing.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] This invention relates to an improvement of an elevator display device. [Prior Art] FIG. 4 shows a conventional elevator display device.

At the landing (100) of each floor of the elevator, various display devices are installed near the door (102) to indicate the movement and status of the elevator to passengers waiting at the landing.

A hall lantern to indicate the arrival of the elevator, a landing indicator (101) to indicate the location of the elevator,
There are directional lights that indicate the operating direction of the elevator, full lights that indicate when the elevator is full, and dedicated operating lights that indicate that the elevator is in dedicated operation.
1) Directional lights.

Full-occupancy lights, etc. are often installed on all floors, and they output a signal to each display at each floor landing at the same time, causing them to turn on at the same time.Also, the display formats of the display devices include continuous lighting and flickering lighting. 2. For example, as shown in Japanese Patent Application Laid-Open No. 59-177283, the elevator lights up continuously while the elevator is stopped, and flickers to indicate the location while the elevator is running.

[Problem to be solved by the invention]

Conventional hall display devices are configured as described above, and two hall display devices are installed on multiple floors.

- If the number of lights on one display is large because the indicators were turned on all at the same time.1 For example, in a multi-stop elevator with many stops, or when multiple lights are installed on the same floor such as a full-time light or a dedicated operating light. In order to light up the display, it is necessary to change the power supply for lighting the square S display to one with a larger capacity according to the number of displays, which increases the amount of electricity used, increases the cost of the power supply, and There were problems such as an increase in the installation space for the power supply device.

This invention was made to solve the above-mentioned problems, and provides an elevator display that can suppress an increase in the electrical load on the entire 9-display display and also suppress an increase in the capacity of the power supply device for lighting the 1-hall display. The purpose is to obtain equipment.

[Means to solve the problem]

In the elevator display device according to the present invention, the flicker lighting timings of the display devices on each floor are staggered so as not to overlap with each other.

[Function] In the elevator display device of the present invention, the flicker lighting timings of the display devices on each floor are set so that they do not overlap with each other, so that the current flowing through the display devices on each floor is dispersed, so that the ¥7L flow is not concentrated. The load on the power supply device can be reduced.

[Embodiments of the invention]

An embodiment of the present invention will be described below with reference to FIGS. 1 to 3. Figure ta1 and Figure 2 show an elevator with nine stops divided into three groups: 1st to 3rd floors, 4th to 6th floors, and 7th to 9th floors. (Ia), (

In addition, 1. Second and third flicker relays (4) to (

(4FL to 6FL) and (7F'L to 9FL,) function as a display driving means for lighting and driving, and also a combination of contacts (9a) and (8b) and the first lag dropout timer σG. Circuit, contacts (5a) and (4

It functions as a switching means that selectively operates the circuit and cycles at predetermined time intervals.

Next, the operation of this embodiment configured as described above will be explained.

When the flicker start command relay is energized at time t1 and the normally open contact (1a) is closed, the fields - (1a) - (3b) -

The initial setting relay (3) is energized by the circuit ←). As the initial setting relay (3) is energized, the normally closed contact (5b) is opened, so the first lag dropout timer αG starts counting the time, and when the time ends at 9 time t2, the first lag dropout timer αG starts counting. The flicker relay (4) is de-energized and the indicators (1FL) to (5F'L) are also extinguished, and the first lag dropout relay (5) is not de-energized yet, so (+') - (1a )−(sa)=(sa)−(4b

When the second lug dropout relay (7) is deenergized, the normally open contact (7a) opens so that the third lug dropout timer 〇? When the timer starts counting and ends at 9 time t4, the third 7 trigger relay (8) is deenergized and the display (7FL'l~(9F

The sequence described above is repeated.

As shown in the timing chart in Figure 3, @1. 2nd and 3rd 7 flicker relays +41 +61 (81 generates flicker signals so that they do not overlap each other, and the indicators (1FL) to (3FL) on the 1st to 3rd floors are connected to the first flicker relay 14). With the normally open contact (4a), the display on the 4th to 6th floors (4F

) flicker.

In the above embodiment, the hall display is divided into three groups, but it may be divided into two or three or more groups.
L may also be used.

Also, if you want to distinguish the status of the elevator with a single indicator, such as when the elevator is stopped or running.

This is possible by changing the flicker cycle.In particular, if the flicker cycle is shortened to such an extent that the human eye cannot distinguish flickering, the 1 boarding area display will appear to be continuously lit, and it will be possible to do so by changing the flicker cycle. It is also possible to do this.

〔Effect of the invention〕

As described above, according to the present invention (i. It also has the effect of not increasing energy.
