Abstract

The present invention relates to an apparatus and method for monitoring, comparing, and analyzing a change in load of a motor drive-type stage setting, which apply an algorithm, adapted to constantly monitor, compare and analyze the amount of load applied to a motor, to a motor drive-type stage setting, and thus the apparatus and method for monitoring, comparing, and analyzing change in load of motor drive-type stage setting can induce a user to check and maintain the stage setting in advance, thereby preventing inconvenience and cancelation of performance from being caused by a sudden mechanical failure, protecting people from a safety accident and the like, and contributing to success of performance. For this purpose, the method for monitoring, comparing, and analyzing a change in load of a motor drive-type stage setting according to the present invention comprises the steps of: determining whether an instruction for moving a batten is present; when the instruction for moving the batten is present, checking a moving direction, and performing a location moving instruction and residual distance calculation; determining whether a location of the moved batten corresponds to a limit location; stopping when the location of the moved batten corresponds to the limit location; and determining again whether the instruction for moving the batten is present. The method for monitoring, comparing, and analyzing a change in load of a motor drive-type stage setting monitors a load factor from a start of lifting or lowering of a batten, calculates and backs up an average value or maximum value of the load factor, provides a warning to a stage director or stage setting administrator in advance when a load factor higher than a preset load factor is detected, induces the stage director or stage setting administrator to perform regular check when the warning is a minor warning, induces the stage director or stage setting administrator to perform emergency checking when the warning is a strong warning, and executes a forced stop when the warning is an urgent warning.

Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a monitoring apparatus,

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a motor-driven stage apparatus, and more particularly, to a motor-driven stage apparatus in which an algorithm for monitoring and comparing and analyzing a load of a motor is always applied to induce inspection and maintenance of a stage apparatus in advance, The present invention relates to an apparatus and method for monitoring and comparing load fluctuations of a motor-driven staging device that protects persons from inconveniences caused by breakdowns, cancellation of performances, safety accidents, and contributes to successful performances.

As shown in FIG. 1, a conventional motor-driven stage apparatus includes a batten 10 installed in a room to carry a stage set, a batten driving unit 20 for moving the batten 10, A pulley chamber 30 installed to connect the battens 10 and the battens driving portion 20, a machine room 40 capable of storing the driving motor and the control panel, (50).

The operation of the conventional motor-driven stage apparatus configured as described above will be described with reference to FIG.

First, it is determined whether or not the movement instruction of the batten 10 is made (S1). If there is a movement instruction of the batten 10, the movement direction confirmation S2, the position movement instruction S3 and the remaining distance calculation S4 are executed It is judged whether or not the moved batten position is in the specified position (S5). If the moved batten position is stopped (S6) once again in the prescribed position, it is judged again whether or not the movement instruction of the batten 10 is made (S7).

Also, in the case of returning, the movement direction of the batten 10 and the remaining distance are computed and a movement command is issued, and the batten 10 moves to a certain distance to determine the original distance and stops.

The conventional motor-driven stage apparatus moves up and down a certain distance or more when the moving distance is determined. In addition, the stage equipment is equipped with various safety devices. Problems caused by slackening or cutting of wire cause alarm to be output to the detecting device and stop.

However, before the wire is cut, it is difficult to detect in advance that the wire is twisted, mechanically caught, or the bearing is broken.

Therefore, it is necessary to always detect the occurrence of an accident at a late time and send out an alarm sound, and then check it.

In other words, monitoring the load in the prior art is shown in the drive, but if it is not utilized, it will fall into garbage data. If a person can not always look at the drive and look at it,

Therefore, a problem of the prior art is that it can not be used for reasons such as machine indentation, malfunction,

There is a problem that even if the state of the stage apparatus is getting worse, nothing can be done to an extreme situation (for example, fall of a batten, burnout of a drive, cutting of a rope, breakage of a mechanism).
