Abstract

PROBLEM TO BE SOLVED: To control an elevator while considering of wills of an elevator user and a controller by judging a traffic demand by the elevator and allowing the elevator of a control object to carry out exclusive driving when its level is lower than a previously set level. SOLUTION: A traffic demand judgement computation processing part 12 judges a current traffic demand in accordance with information of a load sensor, a hall call, a car call, etc., installed under a floor of a passenger car and computes its result numerically in accordance with a size of the traffic demand. An exclusive driving allowing signal generating part 13 decides to allow exclusive driving when a numeric value of the traffic demand judgement computation processing part 12 is lower than a previously set numeric value and puts on an allowing signal. A drive control part 14 carries out exclusive driving only in the case when the exclusive driving allowing signal is on and an exclusive driving button set on an operation panel in the passenger car is pressed on by an elevator user, directly travels the car to a destination stair currently registered in the car and never responds to another hall call.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator operation control device, and more particularly to a traffic demand and an elevator manager.
The present invention relates to an elevator control device capable of capturing a user's intention.

[0002]

2. Description of the Related Art In a conventional elevator control apparatus, a current traffic demand is detected based on elevator user data, and an appropriate operation control method is automatically selected and executed.

[0003] In a group management control device that realizes individualization control, an operation that emphasizes transportation capacity is performed in a time zone where traffic demand is high, and an operation that reduces the number of rides between users is performed in a time zone where traffic demand is low. .

[0004] In an elevator installed alone,
It adopts a driving system that responds to the registered calls regardless of traffic demand.

[0005]

In the prior art, the control system is determined by the judgment of the elevator side, and the control device does not easily reflect the intention of the actual user of the elevator.

[0006] In addition, elevators in which a switch is provided in a car and which can perform so-called dedicated operation that does not respond to other hall call registrations have been put into practical use. However, the operation of the switch is limited to those who have been given a specific authority. The fact is that you can operate. Therefore, general users cannot operate the switch.

[0007] Consider a single-installed elevator.
In a situation where one user does not like to ride with another user, we would like to perform the above-mentioned dedicated driving in the car,
Since the switch cannot be operated, the intention of the user has been ignored.

However, if the general user can use this switch for exclusive operation, the abuse of the exclusive operation function will force other elevator users to wait in the elevator hall for a long time. Many effects.

SUMMARY OF THE INVENTION An object of the present invention is to provide an elevator control device that implements an operation control system while considering the overall traffic demand and taking in the intention of an elevator user.

[0010]

In order to achieve the above object, the present invention provides means for detecting traffic demand, and non-coupling operation (hereinafter, dedicated operation) when the traffic demand is determined to be small based on the detection result. The system includes a device for generating a permission signal and a dedicated operation registration device for inputting a dedicated operation request of a user or an administrator. Further, by providing a device for notifying that a dedicated driving is currently being permitted from the current traffic demand, a control device more convenient for users and managers is provided.

The elevator determines traffic demand, and if the level is equal to or lower than a preset level, determines that the current traffic demand of the elevator is small, and permits the elevator to be controlled to perform a dedicated operation. At the same time, a display such as "exclusive operation is permitted" is displayed on a display device provided in the car or the like. If the user of the elevator desires dedicated operation, he or she operates a switch or button provided on the operation panel to register his / her intention on the elevator side. The elevator does not answer other registered calls during dedicated operation and completes the current service first.

On the other hand, if the traffic demand is larger than the above-mentioned level, the exclusive operation is not permitted, and the above-mentioned "exclusive operation is being permitted" is turned off. In this state, even if the user operates the dedicated operation registration button or switch, the exclusive operation is not performed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of an elevator control apparatus according to the present invention will be described below in detail with reference to the drawings.

In this embodiment, a single-installed elevator having a capacity of 15 and serving the seventh floor will be described as an example. However, the present invention can also be applied to a group management system that efficiently controls the operation of a plurality of elevators.

FIG. 1 is a block diagram showing a system configuration according to an embodiment of the present invention.

In FIG. 1, 1 is an elevator control device, 2 is a sensor for detecting a load in a car mounted under the floor of the elevator car, and 3 is a dedicated operation installed on an operation panel in the car. A registration button, 4 is an indicator light for indicating that exclusive operation is being permitted, 5 is an indicator for displaying the current position of the car, 6 is a rope for raising and lowering the car, 7 is a car, A transmission line that communicates information between the elevator hall and the elevator control device 1 by communication,
8 is a car. In addition to the three buttons, buttons 1C to 7C for registering the destination floor are installed on the operation panel in the car. Buttons 1HU, 2HD,... 7HD for registering calls by direction are provided on the elevator hall side.

Next, an outline of the operation of the present system will be described. When the hall call button 1HU is pressed on the first floor, this information is sent via the transmission line 7 to the elevator controller to make the car 8 respond. The car arrives at the first floor platform, and the user who has been waiting in the hall registers the destination floor by getting into the car and pressing the destination floor button on the operation panel.

In general, if there is a hall call in the same ascending and descending direction from the boarding floor to the destination floor, the hall stops and the user is boarded in order to respond to the call. If it is determined that the demand is small, a dedicated operation permission signal is issued, and the indicator lamp 4 in the car is turned on. As a result, if the elevator user in the car desires the dedicated operation, the intention is notified to the elevator control device by pressing the dedicated operation registration button 3. In addition, if the user does not particularly desire dedicated driving, the normal driving method will be implemented,
Other users will also board from the middle floor.
Details of the elevator control device will be described later.

If inconvenience such as an increase in the waiting time of a user waiting on another floor is expected when permitting exclusive driving depending on traffic demand, the exclusive driving permission signal is not issued. Instead, the vehicle will be operated in the normal riding mode.

Further, a switch for exclusive operation permitted only to a specific user described in the prior art can be installed together. For example, a box with a key is provided in the operation panel, and a dedicated operation switch is installed therein. Since this switch can be used only by a specific user having the key, it is possible to prevent abuse of the dedicated driving. A general user can register a dedicated drive only during a dedicated drive permission determined by the elevator.

FIG. 2 illustrates details of an elevator control apparatus according to one embodiment of the present invention. Reference numeral 11 denotes a communication control unit, 12 denotes a traffic demand determination calculation processing unit, 13 denotes a dedicated operation permission signal generation unit, and 14 denotes an operation control unit.

The communication control unit 11 is a device for controlling the exchange of information between the car 8, the elevator halls on each floor, and the elevator control devices. The traffic demand determination calculation processing unit 12 includes a load sensor 2 installed below the floor of the car.
A known processing method for determining the current traffic demand is performed based on information such as hall calls 1HU to 7HD and car calls 1C to 7C, and the result is calculated numerically according to the magnitude of the traffic demand. If the numerical value of the traffic demand determination arithmetic processing unit 12 is equal to or less than a preset numerical value, the dedicated driving permission signal generating unit 13 permits the dedicated driving and turns on the permission signal. If the value is larger than a preset value, the exclusive operation is not permitted and the permission signal is turned off. The operation control unit 14 performs the exclusive operation only when the exclusive operation permission signal is turned on and the exclusive operation registration button 3 is pressed, and goes directly to the destination floor registered in the current car and does not call other halls at all. Do not respond. If the exclusive operation permission signal is off or the exclusive operation registration button is not pressed, the exclusive operation is not performed.

Although the dedicated operation registration button 3 is installed in the car in this embodiment, it may be installed in an elevator hall, or may be installed in a monitoring room so that an elevator administrator can operate it. Alternatively, the dedicated operation permission indicating lamp 4 may be provided with a speaker in the car instead of the car to provide guidance by voice.

[0024]

According to the present invention, it is possible to realize an elevator control device that takes in the intention of the elevator user / manager and takes into account the efficiency of the entire elevator.
