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.

[0002]

2. Description of the Related Art When a passenger gets on 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, particularly, an adjacent push button. In such a case, the elevator will stop at an unnecessary floor, causing a time loss and deteriorating the operating efficiency of the elevator.
Conventionally, in order to prevent such a situation, JP-A-56-6
As described in Japanese Patent No. 1279, there has been proposed a technique in which the car call on the destination floor is canceled by pressing the push button on the destination floor that was accidentally pressed again.

[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, if the passenger's car is full and the adjacent destination floor to push the desired destination floor is also pushed, the registration is erroneously registered. Frequently, the elevator accidentally stopped at the wrongly registered destination floor, hoping that some of the passengers would get off at the destination floor without canceling the registered car call.

An object of the present invention is to provide an elevator car call registration device capable of preventing a decrease in operation efficiency caused by accidentally pressing adjacent destination floor registration buttons at the same time.

[0006]

In order to achieve the above object, the present invention provides a plurality of destination floor registration buttons provided in a car of an elevator and a car call is registered by operating the destination floor registration buttons. In the elevator car call registration device, an adjoining registration cancellation circuit is provided for canceling the car call registration of the destination floor registration button when adjacent buttons of the destination floor registration button are simultaneously pressed within a predetermined time period. .

[0007]

Since the present invention is configured in this way, when a passenger mistakenly presses the adjacent destination floor registration button at the same time as the destination floor registration button of the destination floor, the adjacent registration cancellation circuit causes the corresponding destination floor registration button to be pressed. Since the operation for canceling the car call registration and the operation for canceling the car call registration are not necessary, the elevator is not wastefully stopped, the operation efficiency is improved, and the operability at the time of car call registration is improved.

[0008]

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

In the figure, the case of an elevator having three floors will be described. The contacts 1 to 3 and a resistor r of a destination floor registration button (not shown) arranged in a car (not shown) between the power sources P and GN.
1 to r2 are respectively connected in series. Further, the connection points of the contacts 1 to 3 and the resistors r1 to r3 are connected to the input terminals of the call registration circuit 4 for registering the destination floor of the car. 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 The output terminal Q of the RS flip-flop 1C is connected to the set terminal S of the RS flip-flop 1C, and the output terminal Q of the RS flip-flop 1C is connected to the input terminal of the timer 1D that outputs a signal after a predetermined time, for example, one second, The output terminal of 1D is connected to the R terminal which is the reset terminal of the RS flip-flop 1C, and the output terminal of the monostable multivibrator 1E which outputs a pulse of a predetermined width, for example, 1 msec at the rising edge of the input signal.

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

Here, the monostable multivibrator 1B-
3B, RS flip-flops 1C to 3C, timer 1D to
The circuits composed of 3D and monostable multivibrators 1E to 3E are car call time limit setting circuits 1A to 3A, respectively.

The connection point between the contact 1 and the resistance r1 is connected to the first input terminal of the AND circuit 2F having three inputs, and the connection point between the contact 2 and the resistance r2 is of the AND circuit 1F having two inputs. One input terminal and the second input terminal of the AND circuit 2F and one input terminal of the two-input AND circuit are connected. Also, the output terminal Q of the RS flip-flop 1C
Is connected to the other input terminal of the AND circuit 1F, and the output terminal Q of the RS flip-flop 2C is AND
It is connected to the third input terminal of the circuit 2F, and the output terminal Q of the RS flip-flop 3C is connected to the other input terminal of the AND circuit 3F.

The output terminal of the AND circuit 1F is connected to one input terminal of the 2-input OR circuit 1G, and
The output terminal of the AND circuit 2F is connected to the other output terminal of the OR circuit 1G and one input terminal of each of the 2-input OR circuits 2G and 3G, and the output terminal of the AND circuit 3F is connected to the OR circuit 2G. 3G and the other input terminal of 3G, respectively.

The output terminal of the OR circuit 1G is connected to the first floor call reset terminal 41 of the call registration circuit 4, and the output terminal of the OR circuit 2G is connected to the second floor call reset terminal 42 of the call registration circuit 4. The output terminal of the OR circuit 3G is connected to the third floor call reset timer 43 of the call registration circuit 4.

Next, the operation will be described.

Now, when the destination floor button on the third floor is pushed by mistake and the destination floor button on the adjacent second floor is pushed at the same time, 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, a signal is output 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, the output terminal Q of the RS flip-flop 3C sends the H signal to the other input terminal of the AND circuit 3F and the timer 3
Output to D. If the destination floor button on the adjacent second floor is pressed within 1 second after the timer 3D inputs the H signal,
A P-2-r2-GN circuit is formed, a potential difference of the same potential as the power source P is generated in the resistor r2, and the H signal is output to one input terminal of the AND circuit 3F. Since the H signal is input to both inputs of the AND circuit 3F, the OR circuit 2
The H signal is output to the other input terminal of G and 3G, and the output of each of the OR circuits 2G and 3G becomes 2 of the call registration circuit 4.
An H signal is output to each of the floor call reset terminal 42 and the floor call reset terminal 43 to reset the registered calls of the floors 2 and 3.

Further, when 1 second elapses after the H signal is input to the timer 3D, the H signal is output to the monostable multivibrator 3E, and the monostable multivibrator 3E is 1m.
A 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 terminal of the AND circuit 3F becomes the L signal.

That is, when the destination floor registration button on the third floor is operated, even if the destination floor registration button on the second floor adjacent to the second floor is pressed within a predetermined time, for example, one second, the car call registration on the second floor and the third floor is registered. Is reset.

Although the present invention has been described with respect to an elevator that serves three floors, the same effect can be obtained although the circuit is naturally complicated regardless of the number of floors.

[0022]

According to the present invention, when a passenger erroneously presses the adjacent destination floor registration button along with the destination floor registration button of the destination floor, the adjacent registration cancellation circuit performs car call registration of the corresponding destination floor registration button. Since the operation of canceling or canceling the car call registration is not necessary, the elevator is not wastefully stopped, the operating efficiency is improved, and the operability at the time of car call registration is improved.
