JP2001151426A - Elevator controller - Google Patents

Abstract

PROBLEM TO BE SOLVED: To provide an elevator controller with highly efficient operation, capable of preventing wasteful operation from being carried out by canceling service corresponding to an elevator car call registration if no passengers are in the elevator car even though an elevator car call has been registrated. SOLUTION: This controller is provided with a load detector 1 detecting the load of a passenger in an elevator, and an elevator car call detector 10 detecting the presence or absence of an elevator call, wherein the load detector 1 and the elevator car call detector 10 are formed so as to cancel service corresponding to the registrated elevator car call if no passengers are in the elevator car even though the elevator car call has been registrated.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator control device for improving the operation efficiency of an elevator.

[0002]

2. Description of the Related Art A conventional technique for improving the operating efficiency of an elevator, which is provided with a load detecting device for detecting the load of passengers in the elevator, is disclosed in Japanese Patent Application Laid-Open Nos. 5-147838 and 5-213543. Etc.

FIG. 3 is a block diagram showing the basic configuration of these prior arts. In the figure, reference numeral 1 denotes a car load detecting device, 2 denotes a car call operation panel, 3 denotes a car call registration button,
4 is a microcomputer, 5 is a load change amount calculator, 6
A car call registration number calculation section, 7 is a speed pattern switching calculation section, 8 is a hoist control section, and 9 is a hoist.

[0004] A conventional device is constituted by the above-described device, and a difference between a load amount when a passenger is in the car and a load amount when the passenger is not in the car is detected by a load detection device attached to the elevator car. When the elevator starts traveling with the load in the car within a certain value and no destination call registration in the car, when the passenger rides on the acceleration / deceleration speed pattern and jerk pattern By making it larger, the traveling time of the elevator is shortened and the driving efficiency is improved. FIG. 4 shows a flowchart for selecting the above-mentioned speed pattern, and FIG. 5 shows the operation characteristics of the elevator according to the speed pattern selected by the above-mentioned flowchart.

[0005]

The above-mentioned prior art changes the running pattern and jerk pattern during acceleration / deceleration of an elevator according to the presence or absence of a passenger in a car.
The driving efficiency is improved by shortening the traveling time of the elevator. However, it is not taken into account that if a passenger accidentally registers a car call and gets off, there is a case in which there is no passenger in the car and there is a case where the car call is operated incorrectly. Unnecessary driving without an elevator user would result in a problem that elevator operating efficiency would be reduced.

[0006] The present invention has been made in view of such deficiencies in the prior art, and its object is to provide a method for registering a car call.
When there is no passenger in a car, the service corresponding to the registered car call is cancelled, and an object is to provide an elevator control device with high driving efficiency that does not cause useless driving.

[0007]

SUMMARY OF THE INVENTION It is an object of the present invention to provide a load detecting apparatus for detecting a load of a passenger in an elevator and a car call detecting apparatus for detecting the presence or absence of a car call. By using the device and the car call detection device, even if there is a car call registration, if there is no passenger in the car, it can be achieved by canceling the service corresponding to the registered car call.

[0008]

Embodiments of the present invention will be described below. FIG. 1 is a block diagram showing an embodiment of the present invention, and the same reference numerals as those in FIG. 3 indicate the same or corresponding parts.
FIG. 2 is a flowchart showing an embodiment of the present invention. In FIG. 1, reference numeral 1 denotes an in-car load detection device, which is provided in an elevator car, detects a load amount of a passenger in the car and sends the information to a microcomputer 4. 2
A car call operation panel provided in the car, the car operation panel includes a car call registration button 3 for designating a floor to which a passenger riding the car wants to go, and the registered car call information Is sent to the microcomputer 4. The microcomputer 4 uses the car call information from the car call operation panel 2 and the load from the load detection device 1 in the car to control the hoisting machine 9.
, A load change calculator 5 for calculating the change in load in the car, a car call detector 10 for detecting the presence or absence of a car call, and a load change calculator 5 for registering the car call. A determining unit for determining a speed command output to the hoist control unit based on information from the detecting unit; and a hoist control unit for controlling torque to the hoist based on information from the speed command determining unit ing. The hoist 9 is a motor that drives the elevator car and operates according to a command from the hoist control unit 8.

Next, the operation of this embodiment will be described with reference to FIG. In the above-mentioned system, if there is no car call registration, or if there is a passenger in the car even if there is a car call registration, a normal service is provided.

Next, if there is no car in the car even though the car call is registered, the car call registration already registered is canceled and the elevator is not driven.
Automatically wait after closing the door.

[0011]

As described above, even if a car call is registered, if there is no passenger in the car, it is determined that there is no use of the elevator user, and the registered car call is handled. By canceling the service, it is possible to provide an elevator control device with high driving efficiency.
