Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator floor guidance display device, and more particularly to an elevator floor guidance display device suitable for power saving.

[0002]

2. Description of the Related Art A conventional floor guide display device for an elevator is disclosed in Japanese Patent Laid-Open No. 56-108678, and when the elevator is not used, the lamp power of the elevator floor guide display device is switched to a rectified current. , A technique for cutting and reducing the power for lighting the lamp has been proposed.

[0003]

In the above prior art, when the elevator is not used, the lamp power of the floor guidance display device is switched from AC to rectified pulsating current, or the lamp power is cut off. Since the lighting state is dark or does not light up, there is a problem that the elevator user feels distrustful, such as not knowing which floor the car is stopped at, or making it seem that the elevator is abnormal.

An object of the present invention is to provide a floor guidance display device for an elevator, which provides a power saving effect without giving distrust to elevator users.

[0005]

In order to achieve the above object, the present invention provides a floor guidance display device of an elevator having a display device for lighting a service floor of a car at each floor landing of an elevator. Is provided with a sensor for detecting the movement of a person near the entrance of the elevator, and the lighting control device for turning on the floor guidance display device provided on the floor is provided at least while the sensor is in operation.

With this configuration, when a user of the elevator approaches the entrance / exit of the hall, the sensor detects it and turns on the floor guidance display device. When the elevator user is not in the hall, the floor is displayed. Since the floor guide display device is turned off, it is possible to obtain the effect of power saving, and it is also known that the power saving measures are being taken without misunderstanding that an abnormality has occurred in the elevator or distrusting the user. Can be tightened.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of the present invention will be described below with reference to FIGS.

FIG. 1 is a power supply circuit diagram showing an embodiment of an elevator floor guidance display device of the present invention, and FIG. 2 is a front view of an elevator hall according to one embodiment of the present invention.

In the figure, the first floor hall F1 of the elevator
A sensor S1 having a contact point S1a for detecting the movement of a person and closing the same is disposed on the upper ceiling 1Fa of the entrance / exit 1, and the car position is displayed on the adjacent wall of the entrance / exit 1
A floor guidance display panel 3 is installed, and this floor guidance display panel 3
Are the car position indicator lights 3A, 3B and the ascending / descending indicator lights 3C,
3D and a landing button 3E for registering an ascending call are provided.

Also, as in the first floor hall F1, not shown in FIG.
The second floor guide display panel (not shown) is provided with a sensor S2 having a contact S2a at the floor as well as the car position indicator lights 4A and 4B, an ascending / descending indicator light (not shown), and an unillustrated hall button for registering a descending call. It is provided.

The power source P-N has sensors S1 and S2.
Are connected in parallel, and when the contact point S1a is energized between the power supplies P and N, the time relay T1 having a contact point T1a which maintains the closed state for 5 seconds which is a predetermined time period even if the contact point is closed and turned off Connected in series, and similarly, contact 8 between the power supplies P-N
2a and a time relay T2 having a contact T2a that maintains a closed state for 5 seconds after being deenergized are connected in series.

Further, when the car (not shown) is located at the second floor hall (not shown) between the power sources P and N, it is energized. Normally open contact 5a of the second-level detection relay (not shown) and car position indicator lamp 4B
And the contact T2a are connected in series, and the contact T2a is connected in parallel with the normally open contact 6a of the second-floor hall registration relay (not shown) that is energized by pressing a hall button (not shown) provided on the second-floor guide display panel (not shown). Has been done.

In addition, a car (not shown) is provided between the power supplies P and N.
A normally open contact 7a of a not-shown first-floor detection relay, a car position indicator lamp 3A, and a contact T that are energized when the vehicle is located in the floor hall F1
1a is connected in series, and the contact T1a is connected in parallel with a normally open contact 8a of a first-floor hall registration relay (not shown) that is urged by pressing the hall button 3E.

Also, the normally open contact 5a and the car position indicator lamp 4B
The car position indicator lamp 3B is connected between the connection point of the car and the contact point of the car position indicator lamp 3A and the contact point T1a, and the normally open contact 7
The car position indicating lamp 4A is connected between the connection point of a and the car position indicating lamp 3A and the connection point of the car position indicating lamp 4B and the contact T2a.

Next, the operation of the floor guide display device of the elevator thus constructed will be described.

First, when passengers get off from the car (not shown) to the first floor hall F1 via the doorway 1 and go out of the building,
Since sensor S1 does not detect passengers, P-S1a
Since the circuit of -T1-N is open and the contact T1a is open, P-7a-3B-T1a-N and P-7a-3.
The circuit of B-T1a-N is opened, and the car position indicator lamp 3A arranged on the first floor guide display panel is turned off.

Next, there is a car (not shown) at the second floor hall,
When a passenger approaches the doorway 1 of the floor hall F1, the sensor S1
Detects a passenger, a circuit of P-S1a-T1-N is formed, and the time relay T1 is activated, so P-5a-3B
Since the -T1a-N circuit is formed and the car (not shown) is on the second floor, the car position indicator lamp 3B is turned on. here,
Even if the passenger goes away from the doorway 1 and goes to another place, the contact T1a continues to be closed for 5 seconds by the operation of the time relay T1, so that the car position indicator lamp 3B remains lit for 5 seconds.

When the passenger presses the hall button 3E,
Since the normally open contact 8a is closed, even if the passenger moves out of the detection range of the sensor 1 and 5 seconds set by the time relay T1 elapses and the contact T1a opens, P-5a-3B-
Since the circuit of 8a-N is formed, the car position indicator lamp 3B
The lighting state of continues lighting until a car (not shown) arrives at the first floor hall F1.

The same applies when passengers are in the hall on the second floor, and the description thereof will be omitted. Further, although the case of the second floor has been described in the present embodiment, it goes without saying that the same applies to any number of floors.

[0020]

[Effects of the Invention] When the elevator user approaches the vicinity of the entrance / exit of the hall, the sensor detects it and turns on the floor guidance display device. When the elevator user is not in the hall, the floor guidance display device is Since the light is turned off, it is possible to obtain the effect of power saving, and at the same time, inform the user that power saving measures are being taken without misunderstanding that an abnormality has occurred in the elevator or distrusting the user.
