Abstract

PURPOSE:To eliminate passenger's uncomfortable feelings by turning off a lamp which judges an abnormality based on a signal outputted from illumination abnormality detectors in a car of an elevator. CONSTITUTION:Illumination abnormality detectors 4a-4d in a car detect a change of luminous flux measured by photometers 3a-3d and transmit it as a lamp abnormality signal to an elevator controller 5. When a lamp 2a flickers, a lamp abnormality signal is outputted from the illumination abnormality detector 4a in the car with a contact 4aa in a closed condition to energize a lamp abnormality detection relay 9A coil. For this reason, a normally-closed contact 9Ab is opened and the lamp 2a is turned off. On the other hand, as for the energized condition of the lamp abnormality detection relay 9A coil, a normally-open contact 9Aa which is a self-hold contact is closed to form a self-hold circuit. The self-hold circuit is opened by operating a lamp exchange check button MA to release the lamp abnormality detection relay 9A coil.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator operation controller, and more particularly to an elevator operation controller interlocked with an elevator car lighting device.

[0002]

2. Description of the Related Art As described in Japanese Unexamined Patent Publication No. 5-229770, a conventional device has a heat-sensitive sensor in the vicinity of a car lighting device to detect a replacement time due to the life of the lighting.

[0003]

A failure of a lighting device in an elevator car causes great anxiety to passengers. Further, among the lighting devices, the flicker due to the life of the fluorescent lamp has a problem of using the elevator while making passengers uncomfortable.

An object of the present invention is to detect an anomaly due to lamp flicker of car interior lighting and to turn off only the anomalous lamp to eliminate discomfort to passengers. Another object of the present invention is to provide a good elevator use that does not cause discomfort, avoiding use to passengers of an elevator whose car interior lighting is determined to be abnormal in a group management control elevator consisting of a plurality of units. Especially. In addition, when a large number of landing calls occur, the lighting equipment inside the car does not stop using the elevator, and the abnormal light source, that is, the flicker lamp is turned off. The purpose is to provide a service that responds to congestion even when congestion is achieved by assigning a landing call without giving a pleasant feeling.

[0005]

In order to achieve the above object, a photometer is provided in the vicinity of a lighting fixture in an elevator car,
When the amount of light changes within a certain period of time, it is determined that the lamp, which is the light source, is abnormal, and a signal is emitted to provide a signal for detecting abnormal illumination in the car. In the elevator control device, the object is achieved by shutting off the lamp circuit which is determined to be abnormal based on the signal generated by the in-car illumination abnormality detection device and turning off the lamp. In addition, in order to avoid the use of elevators in which lighting in the car is determined to be abnormal in a group-controlled elevator consisting of multiple units,
A signal emitted from the in-car illumination abnormality detection device is input to the group management control device section, and an elevator in which it is determined that the in-car illumination is abnormal is disconnected from the group management and placed in a standby state. Further, even in the case of congestion when a large number of landing calls occur, the group management control unit can assign the calls to the elevators in the standby state in order to eliminate the long waiting time. .

[0006]

The apparatus for detecting abnormal illumination in the car inputs the data of the photometer provided near the lamp which is the light source. This in-cage lighting abnormality detection device uses the light amount when the lamp is on as a reference for comparison, and when the light amount repeatedly changes for a lamp that emits a constant light amount within a certain fixed time, The flicker abnormality is detected. As a result, the elevator control device shuts off the lighting circuit of the abnormal lamp and extinguishes it, and continues to light other normal lamps. Since the operation is performed in this manner, the inside of the car does not become dark, and the discomfort caused by the flickering of the lamp can be eliminated. In a group management control elevator in which a plurality of elevators that can be controlled as described above are installed, the elevator whose flicker lamp is turned off by the in-car lighting abnormality detection device is disconnected from the group management group and is in a standby state.
In this control, the group management control unit receives the abnormal signal in the car from the elevator control device and controls it. As a result, the passengers of the elevator can always use the elevator with good lighting in the car. However, reducing the number of elevators used during times when the elevators are frequently used causes a long wait. For this reason, in the group management control unit, if a number of landing calls are generated and it is determined that call allocation control is not possible with only the number of elevators with normal car lighting, the elevators in the standby state due to abnormal car lighting Is also controlled so that calls are assigned. By this control, although some of the lights in the car are turned off, it is possible to provide a service in consideration of long waiting time during congestion by using an elevator that eliminates the discomfort caused by flicker.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to FIGS. FIG. 1 shows the overall configuration.
The detection method by the lighting abnormality detection device in a cage is shown. FIG. 3 shows a circuit configuration that turns off only the lamp that is determined to be abnormal by the detection signal. FIG. 4 shows an allocation procedure for a hall call of a group supervisory control elevator composed of a plurality of vehicles.

In FIG. 1, 1 is an elevator car, 2a,
2b, 2c, 2d are illumination lamps in the car, 3a, 3b, 3
c, 3d are photometers, 4a, 4b, 4c, 4d are in-car illumination abnormality detection devices for detecting abnormal illumination, 5 is an elevator control device composed of a microcomputer, 6 is a microcomputer, etc. An elevator group consisting of a plurality of units is controlled by the constituted group management control device. 7 is a landing call button, 8a is a call assignment command,
8b is a group separation command, and 8c is an abnormal illumination signal in the car. Next, the operation of this embodiment will be described. The in-car illumination lamps 2a to 2d mounted in the elevator car 1 are light source bodies. Photometers 3a to 3d are installed near these lamps. The data of the photometers are taken into the in-car illumination abnormality detection devices 4a to 4d, respectively. The in-car illumination abnormality detection device detects the flicker of the lamp, which is the light source, and transmits it to the elevator control device 5 as a lamp abnormality signal. Elevator controller 5
Shuts off only the lamp circuit that is judged to be a lamp abnormality based on the abnormality signal and turns off the light. At the same time, the in-car illumination abnormality signal 8c is output to the group management control device 6 that manages a plurality of elevator groups. The group management control device 6 receives the in-car illumination abnormality signal 8c, and outputs a group disconnection instruction 8b to the elevator that has issued the in-car illumination abnormality signal 8c so as to move away from the group management control group. The elevator control device 5 that has received the group disconnection command 8b enters the stand-by state under the independent operation control. Further, the group management control device 6 outputs a call assignment command 8a to the elevator control device that has not issued the in-car illumination abnormality signal 8c in response to the operation of the hall call button 7, and performs group management control.

In a state where this call allocation control is being performed, a large number of landing call buttons are operated, and when it is determined that a long waiting occurs for each landing call button only with the current number of group management control elevators, a standby state is established. A call allocation command 8a is issued to the elevator located in the area, and the elevator is controlled so that service can be maintained.

Next, details of the operation will be described. Figure 1
The in-cage illumination abnormality detection devices 4a to 4d are the photometer 3a.
It is a device that detects a change in the luminous flux measured at 3 to 3d and issues a signal indicating a lamp abnormality. The light flux F [1m] is at time t
When the amount of light passing during [s] is Q [1 m · s], F = Q / t. As compared with the normal lamp having the average light flux F [1m], the lamp having the flicker changes the light flux to f [1m] or less as shown in FIG. In this way, when the value of the average light flux F [1m] repeatedly changes to f [1m] or less within a fixed time, the value of the light quantity Q [1m · s] also changes. The abnormality detection device for detecting illumination in the car detects this change and transmits it to the elevator control device 5 as a lamp abnormality signal.

Next, the operation of turning off only the lamp which is determined to be abnormal will be described with reference to the circuit diagram of FIG.
As an example, the operation when an abnormality occurs in the 2a lamp of FIG. 1 will be described. The other 2b, 2c, and 2d lamps have the same circuit configuration and operate in the same manner.
Now, the lamp of 2a is "ON" of the lamp lighting switch 10.
State and normally closed contact 9Ab of lamp abnormality detection relay 9A
Is lit by. If the 2a lamp flickers in this state, the 2a lamp abnormality signal contact 4aa is output from the in-car illumination abnormality detection device 4a in the closed state as described above, and the 2a lamp abnormality detection relay 9A coil is excited. It Therefore, the normally closed contact 9Ab of the 2a lamp abnormality detection relay 9A on the lighting circuit of the 2a lamp is opened and the lamp is turned off. On the other hand, in the excitation state of the 2a lamp abnormality detection relay 9A coil, the normally open state 9Aa, which is a self-holding contact, is closed and a self-holding circuit is formed. This self-holding circuit is opened by operating the 2a lamp replacement check button MA.
The lamp abnormality detection relay 9A coil is released.

Since only the flicker-causing lamp can be turned off in this manner, the elevator user does not feel uncomfortable due to the lamp flicker. In the group management elevator in which a plurality of elevators that can be controlled in this way are arranged, as described with reference to FIG. 1, it is possible to separate the elevator with abnormal car lighting from the group management control group and enter the standby state. It is a thing. Also, a call allocation procedure when a plurality of landing calls occur will be described with reference to FIG. Step 11
The signal of the landing call generated on each floor is input to the group management control device. In step 12, calls are sequentially assigned to normal elevators that are not in the standby state. Step 13
Then, the arrival time of the elevator for each landing call is predicted and calculated based on data such as the number of landing calls, the number of car calls, the number of cars passengers, and the traveling speed. If the result is a value that can be dealt with only by the number of group management elevators, and if it is a value that can be dealt with, the call allocation procedure is terminated. If it is determined that the correspondence is not possible, proceed to step 14,
A part of the lights in the car is turned off, the call is assigned to the elevator in the standby state, and the call assignment procedure ends.

In the present embodiment, even when a landing call is made at the time of congestion, it is possible to provide an elevator in which long waiting is taken into consideration by using the elevator which eliminates the flicker.

[0014]

According to the present invention, it is possible to turn off only the lamp in which the flicker is generated in the lighting in the elevator car, so that it is possible to eliminate the discomfort to passengers due to the lamp flicker. Further, in a group management elevator in which a plurality of elevators that can be controlled in this way are arranged, a good elevator can be used by separating an elevator whose car interior lighting is abnormal from the group management control group and putting it in a standby state. . In addition, during times when the elevator is frequently used, it was controlled to assign calls to the elevators in the standby state, although some of the lamps in the car lights were turned off.
By using an elevator that eliminates the discomfort caused by flickering, it is possible to provide a service that considers long waiting times during congestion.
