Abstract

The present invention relates to a technology for reducing noise when operating an elevator. In the general method of operating an elevator, there is a defect that causes noise to people by driving the elevator in a uniform driving method regardless of the surrounding environment or conditions. In order to solve this problem, the present invention adjusts the operating speed of the elevator by checking the time required for quieting, such as a night time zone, in a living space such as an apartment. By suppressing the chime or ball driving of the platform, or by adjusting the opening and closing speed of the door to reduce the noise generated during the operation of the elevator.

The present invention relates to a technology for reducing noise during operation of an elevator, and in particular, an elevator noise reduction operation that memorizes a time zone sensitive to noise operation and is suitable for operating at a noise reduction speed without generating chimes or empty noise during that time. It is about a method.

1 is an operation control block diagram of a general elevator, as shown therein, a central processing unit 11 for overall control of the operation of the elevator, a storage device 12 for storing information related to the operation of the elevator, and the center A speed command device 13 which receives the speed command from the processing device 11 and drives the car driving motor; Platform control device 14 for operating a platform chime or ball. Consists of a door control device 15 for opening and closing the elevator door, the operation thereof will be described with reference to FIG.

After the elevator starts to operate normally, the elevator system accepts the platform call and the call, and starts the service for the calls according to the program stored in the storage device 12 (S1-S3).

In order to perform the service for the above call, give the elevator car starting instruction, and perform the service for the platform call or car call at the rated speed of the elevator to inform the arrival of the elevator car when the destination of the target floor is reached. Activate chime or arrival forecast ball (S4-S7)

Subsequently, when the car completes the service of the platform call or the call, and arrives completely at the target floor, the central processing unit 11 opens and closes the door with a regular profile. (S8), (S9).

However, in the conventional method of operating an elevator, regardless of a specific time zone of the day, the elevator is operated at a constant speed at all times. The noise generated damages residents who want to sleep or remain quiet in a residential area such as an apartment. Moreover, there was a defect that was damaged by the arrival prediction chime or the sound of the ball when the elevator reached the landing position.

Therefore, an object of the present invention is to remember the time zones sensitive to noise of the day and to operate at a speed at which less noise is generated when the time zone is reached, and to reduce elevator noise such as not operating chime or arrival forecast ball during operation. To provide a method of operation.

Elevator noise reduction operation method of the present invention for achieving the above object is the first step (ST1-ST4) to set or reset the noise reduction operation flag by checking whether the current time is the noise reduction time zone when the operation of the elevator starts; Step 2 (ST5-ST10) for driving in the noise operation mode or the normal operation mode after confirming the state of the noise reduction driving flag after entering the platform landing call or the ka calling input and receiving the car departure command, and the floor to which the car is intended The third step (ST11-ST14) of determining whether the ball or chime is driven by checking the noise reduction driving flag when reaching the landing position of the vehicle, and the noise reduction when the car arrives at the desired floor and opens and closes the door. A fourth step (ST15-ST18) is performed to check the operation flag to open or close the noise reduction profile or to open or close the normal profile.

3 is a block diagram of an elevator to which the noise reduction driving method of the present invention is applied, and as shown therein, a central processing unit 31 for controlling the operation of the elevator as a whole, and storing all the specifications related to elevator operation. A device 32, a speed command device 33 that receives the speed command that the central processing unit 31 reads out from the storage device 32, and a boarding point control device 34 that manages all signals of the platform. ), A door control device 35 that controls the opening and closing of the elevator door, and a time monitoring device 36 which informs the central processing unit 31 of the time zone in which the elevator is currently operating. Referring to Figures 4 and 5 attached to the operation and effect of the present invention configured as described as follows.

The central processing unit 31, which controls the elevator car before the elevator starts to operate (ST1) and starts normal operation, receives the current time zone from the time monitoring device 36 and performs the current time reduced noise operation. It is determined whether it is a time zone to perform (ST2), and as a result, the noise reduction operation flag is set (ST3), or the noise reduction operation flag reset (ST4) in the noise reduction operation time zone.

Subsequently, the elevator system receives the landing call and the kacall (ST5), and starts the service for the call (ST6). In order to perform the service for the call, a car departure command is issued (ST7). At this time, it is determined whether the noise reduction driving flag is set (ST8). Or will you perform the service for the call (ST10). In the set state, it is a noise reduction operation mode that can reduce the noise.

Here, the method of realizing the noise reduction driving mode is realized by adjusting the highest acceleration of the speed profile of the elevator car, as shown in FIG. In other words, in normal driving mode, profile is made with the highest acceleration a1, and in the low noise mode, the speed profile is made using the maximum acceleration a2, and the car is operated at a lower speed than the normal driving mode. It is possible to reduce the noise generated by the friction noise or the elevator guide roller.

When the car is operated with this variable speed profile and the car reaches the target position on the floor (ST11), it is determined whether the noise reduction flag is set again (ST12). (ST13) If it is in reset state, the ball or chime is operated. (ST14)

Thereafter, when the elevator car completes the service for the platform call or the car call through the driving process as described above and reaches the target floor (ST15), it is again determined whether the noise reduction flag is set (ST16). Opening and closing operation is performed with a speed profile that can reduce the noise generated when opening and closing the elevator door (ST17), and if the reset state, the door is opened and closed with a regular profile. (ST18)

When the elevator door is completely closed, the service for the platform or the calling required initially is completed, and then the process returns to step ST2 for determining the state of the noise reduction flag in order to perform the service for the next call request.

As described in detail above, the present invention memorizes a time zone that is sensitive to noise during the day, and operates at a speed at which noise is less generated when it is reached within the time, and does not operate the chime or the arrival forecast ball while driving. There is an effect that can not harm the people around you.
