Abstract

PURPOSE:To call an elevator servicing at a specific floor without newly providing a specific call button at a hall by operating a lowering ball call button for a preset time, detecting a specific call when the count number of the operation number is the preset number or above, and assigning the specific elevator. CONSTITUTION:A user guest operates a hall call button twice in one second to a specific floor, e.g. underground second floor. A contact Aa2 is opened and closed twice, a counter C is excited by a circuit P-Ba2-Aa2-C-N, a contact Ca1 is closed, and a circuit P-AXa3-Bb2-Ca1-DB-N is formed. A specific call circuit DB is registered, either one of elevators 4-6 is serviced, and the user guest can go to the specific floor with no change.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to an improvement in a control device for a group control elevator, particularly a group control elevator that serves different service floors.

[Conventional technology]

Normally, the service floors of group control elevators are the same,
Depending on the building, service floors such as basement floors and rooftop floors may be unavoidably different due to building facilities or economic reasons. Figure 2 shows a vertical cross-sectional view of the building. Elevators 1 to 3 serve the 1st to 10th floors, elevators 4 to 6 serve the 82nd to 10th floors, and basement floors B2 and B1 serve the 4th to 6th floors. This is an example in which three machines provide service.

In the case of such a group control elevator, for example, underground 81
Even if you register a descending call for the 9th floor to go to the floor, one of the cars 1 to 6 will be selected and assigned, so it is not necessarily the case that cars 4 to 6 will be allocated.
Therefore, as disclosed in Japanese Patent Application Laid-Open No. 56-33364, there are hall call buttons (hereinafter referred to as general call buttons) on each floor.
4 to 6 serving underground floors (hereinafter referred to as specific floors)
A hall call button (hereinafter referred to as a specific call button) is provided to call for a car, and passengers must register this specific call button when going to a specific floor.

[Problem to be solved by the invention]

In the conventional device described above, it is necessary to provide a specific call button on each floor, which increases the cost.

When adding specific calls, there is a problem in that the cost increases significantly.

In order to eliminate the drawbacks of the above-mentioned prior art of the present invention, on the landing floor,
To provide a control device for group management service capable of calling an elevator serving a specific floor without newly providing a specific call button.

[Means to solve the problem]

This purpose is achieved by operating the descending hall call button for a predetermined period of time, counting the number of times the button is operated, and when the count is greater than or equal to the predetermined number of times, it is detected as a specific call, and a specific elevator is assigned. Ru.

[Effect]

According to the present invention, when a customer wants to go to a specific floor,
Operate the descending hall call button a predetermined number of times within a predetermined time. As a result, it is determined that it is a specific call, and one of the 4th to 6th cars will serve the passenger, allowing him to go to the specific floor without changing trains.

[Example] An example of the present invention will be described below with reference to the drawings. The boarding area is on the 5th floor, and is intended for descending calls.

FIG. 1 shows an electrical wiring diagram according to the present invention.

In the figure, P and N are DC power terminals, Ha is a normally open contact of the descending hall call button (not shown) on the 5th floor, and A is a relay that is energized when the descending hall call button is operated.
A a21 A ai is its normally open contact, AX is its contact Aa
is a relay that is energized when , is closed, AXal, AXa
zt AXaa is its normally open contact, L is a response light that lights up when contact AXa is closed, B is a relay that is energized when contact Aa□ is closed, Ba□, Ba2 are its normally open contacts,
Bbl is its normally closed contact, similarly T is the timer, and contact Aa
, for example, counts up one second after closing, and T
b□ is the normally closed contact, C is the counter that counts the opening/closing operation of contact Aa, and when counted twice, an output is generated, Ca1 is the normally open contact, cb□ is the normally closed contact, and DA is the counter C. A general call circuit that calls an elevator serving a general floor when D counts once.
B is a specific call circuit that calls an elevator serving a specific floor when counter C counts twice, Rb□
is a normally closed contact of a relay (not shown) that is energized when the elevator that responds to a down call arrives at the 5th floor, and Ha is its normally open contact.

Next, the operation of this embodiment will be explained.

Now, suppose that a passenger operates the hall call button only once in order to go from the 5th floor to a general floor, for example, the 2nd floor.

Contact Ha closes and relay A is energized. When contact Aa closes, relay AX is energized and contact A
Self-maintained by a□. When the contact A X a closes, the response light turns on, indicating that the call for the 5th floor descending hall has been registered.

When contact Aai closes, relay B is energized and contact Ba□
The timer T starts counting. By closing the contacts Ba, , and Aa, the counter C
counts 1. When 1 second has elapsed, the timer T counts up, contact Tb opens, and P-AXa, -Bb
Circuits 1-Cb and -DA-N are formed, a general call circuit DA is registered, and the most suitable elevator among elevators 1-6 serves. When the elevator arrives, contact Ha closes, contact Rb1 opens, and counter C,
Relay AX and general call circuit are reset.

Next, in order for the customer to go to a specific floor, for example, the second basement floor,
Assume that the hall call button is operated twice in one second. Contact A a
2 opens and closes twice, so P-Ba, -A a 2-
The υ counter C is energized by the circuit of C-N, the contact Ca1 is closed, and P-AXa, -BblCa, -D B -N
A circuit is formed, a specific call circuit DB is registered, and any of elevators 4 to 6 provides service, allowing customers to go to a specific floor without changing trains.

In addition, in the above embodiment, a specific call circuit is registered when the hall call button is operated twice in one second, but it is not necessary to limit this time to one second and the number of times to two. The set time and number of times can be set arbitrarily according to the request.

Further, although this device is constructed using a relay, it is of course possible to construct the device using a microcomputer.

As described above, according to this embodiment, an elevator serving a specific floor can be called by using a hall call.

〔Effect of the invention〕

As described above, according to the present invention, if a hall call is operated a predetermined number of times within a predetermined time, a specific floor is serviced, so there is no need to newly set up a specific hall call as in the past, so an inexpensive device can be used. can be provided.
