Description

Elevator control device and method with playfulness prevention function

The present invention relates to an elevator having an anti-noise function, and in particular, when the service request floor registration is excessive compared to the number of passengers, it is possible to cancel without starting the car, and the passenger's mischief range is completely reduced. The present invention relates to an elevator control apparatus and method having a mischief prevention function, characterized by having a configuration and a control method for limiting calling.

Conventional elevator systems have a basic mischief-proof feature, which means that the load on the bottom of the cage can be checked to detect the passenger's load. There is a device that checks how many passengers are based on the rated load of the car by attaching a differential transformer, etc., in which a difference occurs, and cancels all the calls of the car by investigating that there are many and few calls depending on the input signal of the device. There is a built-in program.

This function can be obtained simply by the load tester. The reference system does not activate the play function when a load of 20% or more of the rated load is detected.

However, if the load is less than 20% of the rated load, the system recognizes 1-2 people as boarding (slightly different depending on the rated load), and if there is more than 80% of the floors that can be serviced in this state, It has a built-in program that counts calls as canceling all calls.

1 is a block diagram of the elevator control device having a mischief prevention function, a call recognition device (1) for recognizing this when a passenger who intends to use the elevator operates the floor switch inside the car, and more than 80% of the floor number When the push is pushed, it is determined that there is a possibility of mischief and the mischievous device (2) for outputting the data, and if the load of the elevator is less than 20%, the car load detector (3) ) And the data of the mischief checking device 2 and the car load detecting device 3 are combined and 80% or more of the floors are pushed and at the same time the elevator load is less than 20%. It is composed of a central processing unit (4) with a program to turn off all of the lamps.

The central processing unit (4) is a car control device (4-1) for controlling the flow of the car, the mischief determination device (4-2) for judging the presence or absence of mischief, and check the call by the user's operation and play If it is determined that the call control device for canceling the call (4-3).

As shown in FIG. 2, the operation sequence of the elevator incorporating the general mischievous program configured as described above is determined by the first step T1 of determining whether there is a call registration and starting the car if there is a call registration; A second step (T2) of determining whether the number of calls is 80% or more of the number of floors, and setting the playfulness confirmation flag if the call is more than 80%, and resetting the playfulness flag if not more than 80%; It is determined that the elevator is at the deceleration time, the deceleration time is set, the playfulness confirmation flag is set, and at the same time, a third step T3 is performed to cancel all calls if no load of 20% or more is detected.

However, if the first call occurs before the mischief is detected, the door closes and starts the service, cancels the call if it is recognized as mischief after servicing the top floor. Even if a% is detected, if there is a mischief (all floors are registered), there is a problem of servicing all, and even if not 20%, 80% cannot be registered. Even if one person registered four floors, there was a problem that it was not regarded as a joke.

The present invention is to solve the above problems, it is possible to cancel without departing the car when the number of passengers to register the service demand over a certain number of passengers for a certain time, and completely reduce the range of passengers' mischief, even during operation of the elevator Its purpose is to restrict calling.

As a means for achieving the above object,

According to the present invention, a call recognition device that checks the number of operation of the car call switch, a car load detection device that checks the load applied to the car, and the data of the call recognition device and the car load detection device are summed up to determine the mischief. In the mischief blocking device consisting of a central processing unit for turning off the lamp of the response device,

It is connected to the call recognition device and receives a signal, and if the contact point of the first registration timer is turned on, the call schedule timer device that outputs the play call blocking signal is regarded as a play call when the number of calls up to the prescribed value is exceeded, and the door If the mischievous call is confirmed in the open waiting state of the car or the car is not in operation, the call is canceled and the operation stops even when the door is closed. It is characterized by having a structure to be incorporated in the device.

Hereinafter, a detailed description will be given with reference to the accompanying drawings, in which blocks having the same function as the prior art have the same number.

3 is a block diagram of the present invention, which includes a call recognition device 1 that checks the number of operation of a car call switch, a car load detection device 3 that checks a load applied to the car, and the call recognition device 1. 1) in the mischief blocking device consisting of the central processing unit 4 which turns off the lamp of the call answering device when the mischief is judged by combining the data of the car load detecting device 3) and

Connected to the call recognition device (1) receives a signal and when the contact of the first registration timer is turned on, the call schedule timer device (6) to determine the number of calls up to that time and outputs a prank call confirmation signal if it is above the prescribed value. ) And the number of calls check device (7), and if the play is confirmed in the open standby state of the door or the car is not in operation, the call is canceled and the operation is stopped even when the door is closed, It has a configuration in which the central processing unit 4 has a program for canceling all calls after servicing the floor.

In the present invention configured as described above, if there is a call, the call recognition device detects it and transfers the call to the elevator central processing unit 4 to control the system and simultaneously call a schedule timer to start a timer that is operated for a predetermined time. Output an on signal to the device 6.

At this time, the call schedule timer device 6 requests the call number checking device 7 to grasp the call number together with the signal received from the call recognition device and starts the timer.

The call number checking device 7 grasps the number of calls during the operation of the timer of the call schedule timer device 6, and if the call recognition device 1 is operated, the number of calls until the car stops is also determined. It transfers to the processing apparatus 4.

This data is aggregated in the central processing unit 4 to register multiple floors (based on the data of the call count check device) within the time taken by a person (in the time check time of the call schedule timer device) or as a result of the car load detection device. Even if the load is less than 20%, if the result of the call number checking device is 80% or more, it is regarded as a joke and all calls of the call answering device are canceled.

The background for developing such a device is as follows.

Typically, when a passenger uses an elevator, the door is opened to enter and register the destination floor first.

At this time, even if it is registered as fast as possible, it takes about 200 시간 -300 시간 per floor, and it takes more than 1 ~ 2 seconds for different people to register. Therefore, when a passenger registers several floors simultaneously or sequentially, the time required may be less than the number of floors registered, and the system detects this moment and calls every call even when the door is closed automatically (approximately 2-3 seconds). The car is prevented from being driven by the cage calling, and even if the car starts without a joke, even if there is a continuous calling before stopping at the top, it is also considered a joke and after service to the bottom, all calls are made. By canceling it, it is possible to solve the problem of the prior art which detects the hardware side having low reliability.

When the present invention configured as described above is shown in the operation sequence, as shown in Fig. 4, when the door is opened by a service by a car or a service by calling a hall, the number of floors the passenger wants to go to board is registered. Step S1; A second step (S2) of starting a timer having a minimum time that one person can register after registering for the first call; When the contact point of the first registration timer is turned on, the number of calls up to that time is determined and the new call is made within 2 seconds when it is programmed to be recognized as a joke if more than 3 levels are registered within 2 seconds. A third step S3 of recognizing a mischief if the number is three or more; A fourth step (S4) of canceling the call if the door is in an open standby state or a state in which the car is not operated in the state of being recognized as a mischievous call in the third step (S3); A fifth step (S5) of repeating the second step (S2) when the additional registration occurs by determining whether additional registration has occurred in the state where the car has started; A sixth step (S6) of recognizing a mischievous call when the mischief recognition set signal is output in the third step (S3) and the load is less than 20% and at the same time there is more than a reference number of calls; After recognizing the mischievous calling in the sixth step S6, the seventh step S7 of sequentially starting deceleration for canceling the call and canceling the call when the deceleration is completed is sequentially repeated.

As described above, the present invention adds a device and a program for determining mischief using registration timing, so that when a service request floor registration is excessive compared to the number of passengers for a given time, cancellation is possible without starting the car. By completely reducing the range of passengers' mischief calling, there is an effect of limiting the calling even during operation of the elevator to induce registration.
