Abstract

PROBLEM TO BE SOLVED: To prevent power consumption from increasing without lowering the general operating efficiency by providing a car call registration detecting means detecting the registration of the car call and a car call registration preventing means preventing the registration of a car call adjacent to an arbitrary direction in the car call. SOLUTION: When a second-floor car call button 2 is pressed with a car stopped at the first floor, a second-floor car call registration relay 52 is energized and the second-floor car call is registered. When a third-floor car call button is pressed, a third-floor car call relay 53 is energized and a third-floor car call is registered. Then, a normally closed contact 53b is opened so that the second-floor car call is cancelled. When a forth-floor car call button 4 is pressed, a forth-floor car call registration relay 54 is energized and a forth-floor car call is registered. Then, a normally closed contact 54b is opened so that the third-floor car call is cancelled. If the third-floor car call button 3 is pressed afterward, this device is so formed as to prevent the third-floor car call registration.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an elevator control device.

[0002]

2. Description of the Related Art In a conventional apparatus, a passenger operates a hall call button provided in a hall to call an elevator to get into a car, and registers a car call button provided in the car, whereby a destination floor is registered. To be commissioned. Further, as described in JP-A-7-81852, in order to limit short-distance inter-floor operation, a configuration is set in which the possibility of car call registration is set according to the floor of a passenger of an elevator responding to a hall call. Had become.

[0003]

According to the above prior art, the car call registration on the upper and lower floors of the landing floor is disabled in accordance with the landing floor of the passenger of the elevator responding to the landing call. By avoiding short-distance service from the floor, driving efficiency was improved and power consumption was reduced. However, even when driving as described above, it is possible to register car calls on a plurality of adjacent floors other than the first floor above and below the passenger's boarding floor, thereby improving driving efficiency and reducing power consumption. The decrease is not so promising.

[0004] It is an object of the present invention to provide an elevator control device that prevents an increase in power consumption without lowering the overall operation efficiency.

[0005]

SUMMARY OF THE INVENTION In order to achieve the above object, the present invention relates to a car call registration detecting method for detecting a car call registration in an elevator control apparatus for setting a car to a destination floor in response to a car call. Means for preventing registration of a car call adjacent to the car call in an arbitrary direction.

[0006]

DESCRIPTION OF THE PREFERRED EMBODIMENTS One embodiment of the present invention will be described with reference to FIG. Also, an elevator that cancels or blocks a lower car call among adjacent car calls will be described.

FIG. 1 is a circuit diagram showing an embodiment of an elevator control apparatus according to the present invention.

In FIG. 1, P and N are control power supply lines, 1 to 4 are car call buttons on the first to fourth floors, and these car call buttons 1 to 4 are closed when pressed. 51-54
Is a first to fourth floor car call registration relay indicating that the first to fourth floor car call buttons 1 to 4 have been pressed and registered. 5
2b to 54b are normally closed contacts that open when the car call registration relays 52 to 54 are energized.

A description will be given of a state in which the car is stopped on the first floor in this embodiment. Now, when the second floor car call button 2 is pressed, the P-2 floor car call button 2-normally closed contact 53b is closed because the circuit of the second floor car call registration relay 52-N is closed.
The floor car call registration relay 52 is energized. Thereby, the car call on the second floor is registered. Next, when the third floor car call button 3 is pressed, the third floor car call button 3-normally closed contact 54b-3
Since the circuit of the floor car call registration relay 53-N is closed, the third floor car call registration relay 53 is energized. This gives 3
A floor car call is registered. At this time, since the normally closed contact 53b is opened, the second floor car call registration relay 52 is deenergized. That is, the car call on the second floor is canceled. Next, when the fourth floor car call button 4 is pressed, the fourth floor car call button 4-
Since the circuit of the fourth floor car call registration relay 54-N is closed, the fourth floor car call registration relay 54 is energized. Thereby, the car call on the fourth floor is registered. At this time, the normally closed contact 54b
Is opened, so the car call registration relay 53 on the third floor is deactivated. That is, the car call on the third floor is canceled. Then 3
Even if the floor car call button 3 is pressed, the P-3 floor car call button 3-
Since the circuit of the normally closed contact 54b-3rd floor car call registration relay 53-N is not closed, the third floor car call registration relay 53 is not energized. That is, the third floor car call registration is prevented. Also, the car call registration relay 53 on the third floor is deenergized, and the normally closed contact 5
3b is closed, so the car call registration relay 52 on the second floor is
Pressing the second floor car call button 2 enables registration.

[0010] According to one embodiment of the present invention, when a car call is registered on an adjacent floor, by limiting the car call to the adjacent floor, the overall driving efficiency is not reduced. Thus, an increase in power consumption can be prevented.

[0011]

According to the present invention, when a car call is registered on an adjacent floor, consumption by the car call to the adjacent floor is restricted without lowering the overall driving efficiency. An increase in power can be prevented.
