Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an elevator car call registration device, and more particularly to an elevator car call registration device for preventing erroneous car call registration.

[0002]

2. Description of the Related Art When a passenger rides in an elevator and pushes a push button on his or her destination floor, the passenger often mistakenly pushes a push button on the destination floor, especially an adjacent push button. In such a case, the elevator will stop on an unnecessary floor,
This causes a time loss and deteriorates the operating efficiency of the elevator. Conventionally, in order to prevent such a situation, JP-A-56
There has been proposed a technique in which a car call on the destination floor is canceled by pressing the push button on the destination floor that is erroneously pressed, as described in Japanese Patent No. 61279.

[0003]

The above-mentioned prior art has a drawback that it cannot be used without knowing the method of canceling a car call that is erroneously registered.

Even if the car call canceling method is recognized, for example, when the inside of the car is full and the destination floor of the destination floor is pushed to push the adjacent destination floor, the registration is erroneously registered. Frequently, the elevator stopped at the wrongly registered destination floor without canceling the misregistered car call, thinking that some passengers would get off the destination floor.

An object of the present invention is to provide an elevator car call registration device capable of preventing erroneous car call registration.

[0006]

In order to achieve the above object, the present invention provides a plurality of destination floor registration buttons provided in an elevator car and a car call is registered by operating these destination floor registration buttons. In the elevator car call registration device, when one of the destination floor registration buttons is operated, a car call registration invalidation circuit is provided for invalidating the car call registration of the destination floors other than those registered by this operation for a predetermined time period. It is a thing.

[0007]

Since the present invention is constructed in this manner, when the passenger operates the destination floor registration button of the destination floor and another destination floor registration button is erroneously pressed within a predetermined time period, the operation is initially performed. Operates by operating the destination floor registration button on the destination floor.The car call registration invalidation circuit invalidates the car call registration on the destination floor by another destination floor registration button. This reduces the number of elevators and eliminates unnecessary stoppages of elevators, improving operating efficiency.

[0008]

An embodiment of the present invention will be described below with reference to the drawings.

Referring to the case of the elevator on the third floor in the figure, the contacts 1 to 3 and the resistors r1 to r3 of the destination floor registration button (not shown) arranged in the car (not shown) between the power sources P and GN are described. Each is connected in series. Further, the respective connection points of the contacts 1 to 3 and the resistors r1 to r3 are connected to one input terminal of the two-input AND circuits 1A to 3A, and the respective output terminals of the AND circuits 1A to 3A are connected to the cage. They are respectively connected to the input terminals of the call registration circuit 4 for registering the destination floor. The output terminal of the call registration circuit 4 is connected to the input terminal of the elevator control circuit 5.

The connection point between the contact 1 and the resistor r1 is connected to the input terminal of the monostable multivibrator 1B which outputs a pulse of a predetermined width, for example, 1 msec at the rising edge of the input signal, and the output terminal of the monostable multivibrator 1B is Connected to the S terminal, which is the set terminal of the RS flip-flop,
The output terminal Q of the RS flip-flop is connected to the input terminal of the timer 1D that outputs a signal after a predetermined time, for example, 1 second when a signal is input, and the output terminal of the timer 1D has a predetermined width at the rising edge of the input signal, for example, 1 msec. It is connected to the input terminal of the monostable multivibrator 1E that outputs a pulse, and the output terminal of the monostable multivibrator 1E is connected to the R terminal that is the reset terminal of the RS flip-flop 1C.

The circuit connection from the contact 2 and the contact 3 is also the same, so the description thereof will be omitted.

Further, the output terminal Q of the RS flip-flop 2C connected from the contact 2 and the R connected from the contact 3 are connected.
The output terminals Q of the S flip-flops 3C are respectively connected to the input terminals of the 2-input NOR circuit 1F, and the output terminals Q of the RS flip-flops 1C and the RS flip-flops 3C are connected.
Are connected to the input terminals of the 2-input NOR circuit 2F, and the output terminals Q of the RS flip-flop 1C and the RS flip-flop 2C are connected to the input terminals of the 2-input NOR circuit 3F, respectively. ing.
The output terminals of the NOR circuits 1F to 3F are A
It is connected to the other input terminals of the ND circuits 1A to 3A, respectively.

Next, the operation will be described.

Now, when the destination floor button on the third floor is pushed and the destination floor button on the adjacent second floor is pushed by mistake, the contact 3 of the destination floor button on the third floor is closed and P -3-r3-
A GN circuit is formed, a potential difference of the same potential as the power source P is generated in the resistor r3, an H signal is input to one input terminal of the AND circuit 3A, and the output signals of the NOR circuits 1F to 3F are all H signals. A signal is output from the AND circuit 3A to the call registration circuit 4, and the car call on the third floor is registered.

Simultaneously with the closing of the contact 3, the H signal is input to the monostable multivibrator 3B, and the pulse signal of 1 msec is input to the S terminal of the RS flip-flop 3C. Here, it is input to the S terminal of the RS flip-flop 3C. Here, the output terminal Q of the RS flip-flop 3C
Sends the H signal to the other input terminals of the NOR circuits 1F and 2F,
Since the NOR circuits 1F and 2F output to the timer 3D are switched from the H signal to the L signal, even if the H signal is input to one of the input terminals of the AND circuits 1A and 2A, the signal output to the call registration circuit 4 is not generated. Car calls on the first and second floors are not registered because they are blocked.

Further, when 1 second elapses after the timer 3D inputs the H signal, the H signal is output to the monostable multivibrator 3E, and the monostable multivibrator 3E outputs 1m.
The pulse signal of sec is output to the R terminal of the RS flip-flop 3C, and the output terminal Q of the RS flip-flop 3C changes from the H signal to the L signal, so that the output signals of the NOR circuits 1F to 3F all become the H signal again.

That is, when the destination circuit registration button on the third floor is operated, the car call is not registered even if the destination floor registration on the first floor and the second floor is pressed for a predetermined time, for example, one second.

In the present embodiment, the elevator for servicing the third floor has been described, but the same effect can be obtained although the circuit is naturally complicated regardless of the number of floors.

[0019]

According to the present invention, when another destination floor registration button is erroneously pressed within a predetermined time due to the passenger operating the destination floor registration button of the destination floor, the destination floor of the originally operated destination floor. Since the car call registration invalidation circuit that operates by operating the registration button invalidates the car call registration on the destination floor by another destination floor registration button, false registration of the car call that occurs when the destination floor registration button is operated is reduced, and the elevator call of the elevator is reduced. Operational efficiency is improved by eliminating unnecessary stoppage.
