Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention provides a method for enabling so-called specific operation, such as call registration or operation to a specific floor, by pressing an elevator push button multiple times. The present invention relates to an elevator signal registration device.

[Conventional technology]

The conventional device described in Public Utility Model Publication No. 53-49870 "Elevator Call Registration Device" includes two different examples of methods of calling an elevator by registering an elevator call signal (hereinafter referred to as call registration). ing. One is to register a call by pressing a call operation button (hereinafter referred to as the call button) a predetermined number of times within a predetermined time. Call registration is performed by pressing the special operation push button at the same time.

The former, a device that presses the call button a predetermined number of times within a predetermined time, is equipped with a timer to measure the time it takes to press the call button a predetermined number of times, and a special rotary switch that automatically rotates each time the call button is pressed. This was used to count the number of times the call button was pressed. In the latter case, a special operation pushbutton is pressed together with a call button, in which a separate button is provided and pressed to characterize special call registration. Both required special equipment, such as timers, special rotary switches, or buttons for special operations.

[Problem that the invention seeks to solve]

Conventional devices that press the call button a predetermined number of times within a predetermined time require a special rotary switch and timer, so this method can be extended to the case where the call button is pressed an arbitrary number of times beyond the capacity of the rotary switch or beyond the time limit of the timer. It was difficult to respond to the situation, and it was difficult to use because of the time limit, which was within a fixed time, and it was prone to errors and lacked reliability. Furthermore, this device does not allow for call registration by pressing not only the call button but any push button necessary for driving.

The above problems also apply to another conventional device described in the above-mentioned publication, which is equipped with a push button for special operations and is pressed together with a call button, but this device is even more expensive. Ta.

The purpose of the present invention is to press any push button necessary for operation any number of times without requiring a special rotary switch, time limit within a predetermined time, or push button for special operation as described above. It is an object of the present invention to provide an inexpensive device that allows call registration and signal registration for specific driving by pressing the button, is easy to expand to an arbitrary number of times, and is highly reliable in terms of error occurrence.

[Means for solving problems]

In order to achieve the above purpose, a signal input relay that closes when a push button necessary for operation is pressed, and each time a predetermined number of signals are input through the contacts of this relay, the circuit is closed sequentially in response to each signal. A configuration comprising a plurality of signal detection relays, a signal holding relay that maintains the closed state of each signal detection relay, and a signal registration relay that becomes closed when all contacts of the signal holding relay are closed and registers the signal. And so.

[Effect]

A signal input relay that closes when the push button is pressed is
Pressing any pushbutton provides one input.

The plurality of signal detection relays are sequentially closed each time a signal is input.The first pulse signal generated by pressing a push button is received by the first signal detection relay and is closed, and the second pulse signal is closed. A predetermined number of pulse signals are received by the second signal detection relay to close the circuit, and a third signal is received by the third signal detection relay to close the circuit.

The signal holding relay that maintains that the signal detection relay is closed is the first signal holding relay. Second. As the third signal detection relay becomes closed, each of the corresponding signal holding relays becomes closed, thus converting a predetermined number of signals into closed circuit holding of the same number of relays.

The signal registration relay, which closes when all the contacts of the signal holding relay are closed, enables confirmation functions and registration, such as registering a call or performing a specific operation after confirming that the number of signals has reached a predetermined number. It has the effect of

〔Example〕

An embodiment of the present invention will be explained with reference to FIG.

In Figure 1, LA is a power check relay, 2A is a signal detection relay that receives the first pulse signal, 3A is a signal detection relay that receives the second pulse signal, and 4A is the signal that receives the third pulse signal. Detection relay, A, B,
C is 2A each.

Signal holding relay corresponding to signal detection relays 3A and 4A, D is a signal HSR relay that is closed when all contacts of signal holding relays A, B, and C are closed, and Ea is closed when the push button is pressed. The signal input relay contact (push button output contact), Fb is the signal detection relay 2A ~
A contact point Gb resets a counting circuit such as 4A, and a contact point Gb resets a signal holding circuit such as signal holding relays A to C.

Turn on the power and connect the voltage between P and N in Figure 1! When A'4 voltage is applied, the power check relay IA closes and holds itself, preparing the circuit for operation.

When the first pulse signal is received by pressing the push button in this state, the signal human relay contact Ea is closed and then opened. When Ea is closed, signal detection relay 2A is closed and self-holding, and power check relay I
A becomes an open circuit.

At this time, signal holding relay A is closed and self-holding.

When the second signal comes, the signal detection relay 3A and the signal holding relay B are closed and self-holding, and the signal detection relay 2A is opened.

When the third signal comes, the signal detection relay 4A and the signal holding relay C are closed and self-holding, and the signal detection relay 3A is opened.

As a result of the above, signal holding relays A, B, and C are closed, so signal holding relay D is closed.

If contact D (not shown) is applied to the call registration and specific operation instruction circuit, call registration and specific operation can be immediately performed.

This circuit can be reset by, for example, detecting that the above-mentioned call registration has been performed and entering specific operation, or by detecting that the door has closed or that the vehicle has started driving, and the reset relay is activated as appropriate. This can be achieved by opening contacts Fb and Gb.

In addition, in the above, the circuit was configured by a combination of relays, but
It is possible to achieve similar behavior using logic circuits.

〔Effect of the invention〕

According to the present invention, it becomes possible to press any push button by the action of the signal input relay, and the action of the signal detection relay and the signal holding relay allows the relay to be activated when the push button is pressed an arbitrary number of times. It is possible to provide a highly expandable device that can be handled by simply increasing or decreasing the amount. Furthermore, in combination with the effect of the signal registration relay, call registration and specific operation can be performed with high reliability without malfunction. In addition, the present invention does not require a special rotary switch and is composed of only a relay, and also does not require a push button for special operation. Furthermore, since there is no time limit such as having to press a push button within a predetermined time, it can be made inexpensive and easy to use.

Through the above, the object of the present invention can be achieved.
