JPH107335A - Signal transmission device of elevator - Google Patents

Abstract

PROBLEM TO BE SOLVED: To identify a call kind without installing a new button for a different kind of a call by providing display means corresponding to the classification of a landing call. SOLUTION: When a general call is registered, a relay XA is operated, and a circuit of P-AT1-AT2-response lamp LA of existing buttonATE-ATE-relay XA-N is formed so that the response lamp LA of the existing button is lighted. On the other hand, when a special call is registered, a relay XB is operated, and a circuit of PAT-1-AT2-response lamp LA of existing lamp -AT3-AT4- control resistance R- relay XB-N is formed so that the response lamp LA of the existing button is lighted. As compared with the register of a general call, the lamp becomes darker because the control resistance R is connected in series to the response lamp LA. Thus, it is possible to discriminate the classification of a call according to the lighting condition of the response lamp LA of the existing button in such a manner that if bright, it is a general call, and if dark, it is a special call.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator signal transmission apparatus suitable for adding a call having a different purpose to an existing call by modification or the like.

[0002]

2. Description of the Related Art Conventionally, when a call for a different purpose is added to an existing call button (for example, additional modification of a wheelchair specification), a signal line between the control panel and the additional button is laid independently of the circuit of the existing call button. The response light is lit by a detection relay that detects the operation of the button. This will be described with reference to FIG. In the figure, P and N are DC power supply terminals, LA is a response light of an existing call button, AT1 and AT4 are connection terminals of a control device (not shown) provided in a machine room, and are AT1-AT2, AT3-AT4.
Is a wiring from the control device to the call button, and XA is a relay that is energized when the call button is operated. LB is a response light of a call button of an additional button, and XB, BT2, BT3, B
T4 is the existing relays and terminals AT2, AT3, AT
4, and the terminals AT2 and BT2 are connected.

[0003] Regarding this technology, for example, Japanese Patent Application Laid-Open
JP-A-83959 and JP-A-57-67469.

[0004]

The above-mentioned prior art has a problem in that a machine room and an additional button are provided, for example, when buttons for all floors are installed or when buttons are installed on the lowest floor, such as a modification to a wheelchair elevator. There is a problem that the number of wirings becomes very large. Another problem is that it is very difficult to lay new wiring due to the structure of the building.

[0005] An object of the present invention is to improve the above-mentioned drawbacks, and to provide an elevator signal transmission device capable of displaying differently according to the type of hall call without installing an additional button. is there.

[0006]

The above object is achieved by providing a plurality of hall buttons on a hall and determining the type of hall call to be registered by providing display means corresponding to the type of hall call. .

[0007]

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

FIG. 1 is an electrical connection diagram showing an embodiment of an elevator signal transmission device according to the present invention. The same reference numerals as those in FIG. 2 denote the same parts, and a description thereof will not be repeated.

[0009] In the figure, R is a limiting resistor for lighting the answering lamp so that it is darker than usual, and is connected in series with the existing answering lamp.

Next, the operation of this embodiment will be described.
In order to make the explanation easy to understand, relay XA is energized during normal call registration and relay XB is activated when a special call is registered.
Will be described as being energized.

When a general call is registered, relay XA operates and P-AT1-AT2-LA-AT3-AT4-X
An AN circuit is formed, and the response light LA of the existing button is turned on. This is the circuit that turns on the normal response light.

When the special call is registered, the relay XB operates and the P-AT1-AT2-LA-AT3-AT4-R
The circuit of -XB-N is formed, and the response light LA of the existing button is turned on. Compared with the registration of the general call, the limiting resistor R is connected in series with the answering lamp LA, so that it lights up darkly.

As described above, when the light is turned on brightly, it is possible to determine the general call, and when the light is turned on darkly, it is possible to determine the type of the special call and the call based on the lighting state of the answering lamp.

[0014]

As described above, according to the present invention, a call type can be identified without installing a button for calls of different call types.
