Abstract

PROBLEM TO BE SOLVED: To provide a door control device for an elevator capable of restricting useless door opened time to the utmost for restricting deterioration of operation efficiency to the utmost while securing a necessary and sufficient time for passengers to get on and off. SOLUTION: In this door control device for an elevator provided with a means of automatically closing a door at a first door time after a door stops at a specified floor to open in response to a landing call and a car call, a means is taken to automatically close the door at a second door time that is different from the first door time in case the car call is registered after the door is opened.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to an elevator door control device.

[0002]

2. Description of the Related Art A car door of an elevator stops at a predetermined floor in response to a car call or a car call, and when the door is opened, the door responds to the first door time, for example, a hall call. In this case, a door closing instruction is given after 5 seconds, and after a response to the car call, after 3 seconds. By the way, in recent years, in consideration of the welfare of elevators, in the elevators of the welfare-compatible specification, the first door time is often set to, for example, about 10 seconds uniformly.

[0003]

In the above prior art, if the first door time is set to, for example, 10 seconds uniformly, there is a problem that the driving efficiency is deteriorated when only healthy persons are using the door. Conversely, even if the first door time is secured, for example, 10 seconds, it often takes about 20 to 30 seconds for the user to load the luggage in the car, and the opening button of the operation panel in the car Because the work is done while holding down the door or holding down the safety of the door, the loading of the luggage can not be done smoothly, it takes about 30 to 40 seconds, and the door opening time is rather long. was there.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned situation in the prior art, and has as its object to reduce the operation efficiency by minimizing the useless door opening time while securing a necessary and sufficient getting on and off time. An object of the present invention is to provide an elevator door control device that does not allow the elevator door control.

[0005]

The object of the present invention is to stop at a predetermined floor in response to a hall call and a car call, and to automatically close the door after a lapse of a first door time after the car opens. In the elevator door control device provided with the means, when the car call is registered after the door is opened,
This is achieved by providing a means for automatically closing the door after a second door time different from the first door time has elapsed.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing a schematic configuration of an embodiment of the present invention.

Reference numeral 1 denotes an elevator control device, and 2 denotes an operation control device, which is a known microcomputer control device. Reference numeral 3 denotes a storage device including a ROM and a RAM. The first door time set value and the second door time set value are stored in the ROM in advance, and the processing result of the operation control device 2 is stored in the RAM.
To memorize. Reference numeral 4 denotes an in-car operation panel, which includes a car call button, a door opening / closing button not described in the embodiment, and the like. Reference numeral 5 denotes an input circuit for inputting a peripheral device not described in the present embodiment, which is also connected to an in-car operation panel. 6 is a door time calculator for determining a predetermined time for automatically closing the door after the car is opened, 7 is a car call detector for detecting registration of a new car call, and 8 is a door controller for controlling opening and closing of the door. These are included in the operation control device 2. Reference numeral 9 denotes an output circuit for outputting to peripheral devices not described in the present embodiment. Reference numeral 10 denotes a door driving device which is installed on a car and drives the opening and closing of the door, and is connected to the output circuit 9.

FIG. 2 is a flowchart of the present embodiment.

In step S1, when the operation control unit 2 detects that the car has arrived at the car call and hall call floor and that the car has stopped, the door control unit 8 outputs a door opening command in step S2, and the door drive is performed. The device 10 performs a door opening operation.

In step S3, the car call detecting section 7 determines whether a new car call has been registered during the opening of the door. If no new car call has been registered, the process proceeds to step S4, where the first call is stored in the ROM of the storage device 3. Select the door time setting for
The result is stored in the RAM of the storage device 3. If a new car call has been registered, the process proceeds to step S5, where R
The second door time set value is selected from the OM, and the result is stored in the RAM of the storage device 3.

In step S6, when the operation control device 2 detects the operation of the close button by detecting the close button operation of the in-car operation panel not described in the present embodiment, it is considered that the door time has expired, and the process proceeds to step S9 described later. If the operation of the close button has not been detected, the process proceeds to step S7.

In step S7, the door time calculation unit 7 performs a door time count, and stores the door time count value in the RAM of the storage device 3.

In step S8, the control device 8 compares the door time count value stored in the RAM of the storage device 3 with the door time set value, and the door time count value has not reached the door time set value. In this case, the process returns to step S3, and the door open state is maintained, and when the door time count value reaches the door time set value, the process proceeds to step S9 to detect expiration of the door time.

In step S10, upon detection of expiration of the door time, the door control section 8 outputs a door closing signal to the output circuit 9, the door driving device 10 performs a door closing operation, and the operation control device 2 performs a door closing operation not described in this embodiment. Upon detection of the completion signal, the process proceeds to step S11, and the elevator is started to the destination floor.

In the above operation, when the elevator is used for the purpose of early departure, if the first door time is set large and the second door time is set small, useless door opening time is reduced. Can be omitted. Conversely, when the door time is used to extend the door time when carrying a load, the second door time setting is set to a large value and the first door time setting is set to a small value. You can save time. If the first door time and the second door time are set to the same setting, it is needless to say that the door time can be used at the normal door time.

[0017]

As described above, according to the present invention, there is provided an elevator door control device which minimizes useless opening time of a door and secures a necessary and sufficient getting-on / off time while keeping the operation efficiency as low as possible. Can be.
