DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention]

[0001]

BACKGROUND OF THE INVENTION The present invention relates to a method for canceling an elevator call.

[0002]

2. Description of the Related Art Conventionally, in elevators that service on a plurality of floors, a destination floor button is provided in a car, and when this destination floor button is operated, a call is registered as a car call and a button or a button is located near the button. Is lit, registered and displayed, and the so-called Celecore driving system is operated in which the vehicle is driven and serviced up to the floor. However, useless calls may be registered when the destination floor is erroneously pushed or the operation is not stopped because of a delay. If these calls are left as they are, useless services increase and the operating efficiency decreases. Accordingly, recently, an elevator having a so-called destination floor canceling function for canceling a destination floor call by pressing the useless call again twice has been realized.

[0003]

In the conventional method of canceling the destination floor, when the registered destination floor button is pressed for the first time, the display does not change. Therefore, the elevator controller recognizes the first pressing. Since there was no means for the passenger to confirm whether or not the cancellation was performed, the passenger was worried whether the cancellation operation was performed reliably. In the conventional call canceling method, canceling is performed by pressing the registered button and pressing the button again after a predetermined time.However, when pressing the second time, it is determined whether or not a predetermined time has passed since the first press. Since the passenger could not be confirmed, there was a problem that the passenger thought that the cancellation was possible and pressed the button even though the cancellation became impossible after a predetermined time had already passed.

[0004] The present invention has been made in view of the above-mentioned disadvantages.
There is a call cancellation function with a confirmation function that can confirm that the control device has recognized the second push and that the valid time of the second push can be recognized, eliminating unnecessary driving due to erroneous operation and improving driving efficiency. It is an object of the present invention to provide a method for canceling an elevator call which can improve the service and improve the service. [Configuration of the Invention]

[0005]

In order to cancel a destination floor of an elevator, a call registration display is displayed when a registered destination floor button is pressed for the first time, regardless of the elapsed time after the registered floor button is lit. It changes from lighting to blinking, and indicates that the control device has recognized the first press. In addition, a predetermined time until the second pressing is blinked to indicate that the second pressing is effective. If the user presses the second time during this time, the call is canceled and the display is turned off, but after this time, the display is returned to the original lighting state, indicating that the valid time has passed.

[0006] The flashing display after the first push in this way indicates that the control device microcomputer has recognized it,
Prompting the second operation, the destination floor can be reliably canceled. If the registered button is touched by mistake, the display becomes blinking, but if the button is not operated for a predetermined short time of about 3 seconds, the original display is displayed and the erroneous operation can be confirmed. As described above, the destination floor cancellation function can be used with a sense of security, so that useless driving can be eliminated and energy can be saved and services for users can be improved.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment according to the present invention will be described with reference to the drawings. FIG. 1 is a system configuration diagram of an elevator call canceling apparatus according to the present invention. An embodiment of the present invention will be described with reference to FIG. Reference numeral 1 denotes an elevator control device which controls the hoist motor 3 to operate in response to a hall call (not shown) and a call to the destination floor buttons 6 and 7 of the in-car operation panel 2. 4
Balance weight 5 is a basket. Reference numeral 6 denotes a switch section of a destination floor button, which is a push button or a touch type. Reference numeral 7 denotes a portion indicating the registration display of the destination floor button, which is constituted by an LED or a lamp. The main part of the control device is a microcontroller with a built-in microcomputer of 16 bits, etc., a central processing unit CPU, program storage area ROM, data storage area RAM, digital input DI, digital output DO, motor control unit MCU.
It consists of. In the RAM, at least the destination floor button operation signal () K, the lamp signal L () K and the car call registration signal P
() K has a data area for the floor. FIG. 2 is a time chart when the call canceling method of the present invention can be erased, and FIG. 3 is a time chart when the call canceling method of the present invention cannot be erased.

In FIG. 2, when an unregistered button is operated, a call is registered and the button changes to a lighted display. When canceling the registered call in this way, the first press of the lit display button starts blinking at a cycle of about 2 HZ and continues for a predetermined time (about 3 seconds). If the user presses the second time within the predetermined time, the call is canceled and the registration light is turned off. However, after a predetermined time (about 3 seconds), the registration lamp changes from blinking to lighting, and the second pressing is recognized as the first pressing and starts to blink. If there is no next operation, the light is turned on after a predetermined time. In this way, the effective time of the second push is known.

FIG. 4 is a flowchart of the call canceling method of the present invention. The operation will be described according to this flowchart. RS is a repeat start point, and is a position where execution of a program for realizing this function is started.
At step 1, it is checked whether the destination floor button has been pressed. At this time, at step 2, it is checked whether the call has been registered.
In EP3, the corresponding bit of P () K is set to 1 to register the call, and L () K is also set to output the lamp lighting output. If the call has already been registered, check in step 4 if it is blinking.
Change to lamp blinking output at P5. In step 6, it is checked whether the blinking state of the lamp has passed for 3 seconds.
L () K is set in TEP7 to turn on and output the lamp. If it is blinking in STEP4, it is determined as the second press, and in STEP8, P () K is reset to cancel the call, and L () K is reset to output the lamp extinguishing output. STE even if there is no button operation in STEP1
At P9, it is checked whether the lamp is blinking, and it is checked after 3 seconds in STEP6. After the processing of the series of calls is completed, the vehicle is driven in response to the call in STEP10, and when the response to the registered floor is completed, P () K is reset to clear the call and L () K is reset. The lamp goes off. The above process is repeated. In this way, the call cancellation function is realized.

When the button of the registered call is pressed for the first time, the registered indicator light is displayed in a blinking manner, so that the conventional hardware can be used as it is, and there is no cost increase. Also, 1
There is also a merit that it is possible to confirm that the control device has recognized by the blinking display at the time of pressing the button a second time and conversely, when the controller is accidentally touched. Further, it blinks for about 3 seconds and returns to the original state. Therefore, if necessary, the operation can be performed again by pressing the button twice. It is possible to press not only twice but also three times.

[0011] In the case of canceling the third press, the second blink may be performed, or the blink cycle of the first press and the blink cycle of the second may be changed. Alternatively, instead of blinking display, the display may be changed to a slightly lighted display form instead.

[0012]

When the destination floor canceling function of the elevator is realized, the first push can be confirmed, so that the number of times can be reliably checked. In addition, since the effective time of the second push is known, it is possible to distinguish whether it is the first push or the second push after the predetermined effective time, which is easy for the passenger to operate, and the destination floor cancel function. It is possible to reduce erroneous operations and malfunctions when using. With this function, useless calls such as erroneous operation and mischief can be canceled, so that operation efficiency increases. In addition, the display of the present invention can be economically realized without increasing the cost because the conventionally required hardware can be used as it is.
