Abstract

PURPOSE:To improve the stabilization of production by providing a learning circuit having a leaning function for storing the operational condition of a suspending mechanism or floor mechanism in the rehearsal as speed with reference to position and a reproductive function for operatively reproducing said learning result. CONSTITUTION:A leaning circuit 5 in the rehearsal inputs a speed commanding value S1 set by a sheet setter 1 in a stage mechanism controller 2 and a speed feed-back signal S5 from a pulse generator 4, integrates the signal S5 to convert it to distance data and sequentially store the distance data and commanding value S1 in a function generator in the circuit 5 every time only the set value is changed. In the reproductive operation, the initial operation position is set to the start position A in the rehearsal and then the speed commanding value S6 is taken out of the function generator and given to the controller 2 which supplies power S3 to a motor 4 according to the commanding value S6 to control the motor 3 to the speed thereof. When the stage mechanism is moved thus, the signal S5 is converted to the positional data and a new commanding value S6 is supplied.

Description

[Detailed Description of the Invention] [Object of the Invention] (Industrial Application Field) The present invention provides a stage 4L with a learning function for controlling stage mechanical equipment such as a hanging mechanism and a floor mechanism. The present invention relates to a structural control device.

(Prior art) Stage mechanical equipment is equipped with a suspension mechanism, a floor mechanism, and operating supplies for setting the movement speed, movement position, etc. of the suspension mechanism and floor mechanism, so that the operator can perform the movements desired by the director. It is operated manually, and these performances are rehearsed in advance so that the operators are familiar with the movements desired by the director.

(Problem to be Solved by the Invention) Conventionally, the performance work using the suspension mechanism and floor mechanism in stage equipment has been left to the judgment of the operator, so the effectiveness of the performance may vary depending on the operator's skill level. There was a problem in that the performance was not stable and stable performance could not be ensured.

The present invention has been made in consideration of the above problems, and it is an object of the present invention to provide a stage mechanism control device with a learning function that improves the stability of five performances.

[Structure of the invention]

(Means and effects for solving the problems) In order to achieve the above object, the stage mechanism control device of the present invention adds a new feature to the stage mechanism control device that has been used conventionally. A learning circuit is provided which has a learning function for storing the operating state of the motor as a speed based on the position, and a reproducing function for reproducing the learning result.

During rehearsal, the above learning circuit inputs the speed command value from the speed setting device in the stage mechanism control device and the speed feedback signal in the stage mechanism control device, integrates the speed feedback signal, converts it into distance data, and calculates the distance. Each time the data changes by a preset value, the distance data and speed command value are sequentially stored in the function generator.

On the other hand, during the reproduction operation, the current position is determined from the distance data in the learning circuit, the speed command value at that time is obtained from the function generator, and is given to the stage mechanism control device.
I try to get the same movements as during rehearsal.

By using the above means, for example, when the lifting mechanism is raised in a certain speed pattern during rehearsal, the speed command values corresponding to each position from the start point to the stop point are sequentially stored in the function generator, and the speed command values corresponding to each position from the start point to the stop point are sequentially stored in the function generator. The initial operating position of the suspension mechanism is adjusted to the starting position during rehearsal, and the speed command value at that time is obtained from a function generator and given to the stage mechanism control device, thereby obtaining a speed pattern similar to the speed pattern operated during rehearsal. I'm trying to be able to do that.

(Example) An embodiment of the present invention is shown in FIG.

In FIG. 1, the learning circuit 5 has a learning function that memorizes the speed at that time based on the position of the operating state of the suspension mechanism or floor mechanism during rehearsal, and a reproduction function that reproduces the learning result. The speed command value s1 set by the speed setting device 1 in the stage mechanism control device and the pulse generator 4
The speed feedback signal s5 is inputted, and the speed feedback signal s5 is integrated and converted into distance data.

Each time the converted distance data changes by a preset value, the distance data and the speed command value s1 are sequentially stored in the function generator in the learning circuit 5.

Figure 2 shows an example of a speed pattern stored in the function generator, from starting position A to stopping point B.
Speed command values s1 at a plurality of positions between starting position A and stopping point B are stored as a speed pattern when moving to , and speed command values intermediate between the stored positions are linearly interpolated.

During the reproduction operation, the initial operation position is adjusted to the starting position A during the rehearsal, and the speed command value s6 at that time is taken out from the function generator in the learning circuit 5 and given to the stage mechanism control device 2, and the stage mechanism control device 2 adjusts the speed. Command value s6
Accordingly, power s3 is supplied to the electric motor 3, and the electric motor 3 is controlled to that speed.

As a result, the stage mechanism moves, and the speed feedback signal s5 is input to the learning circuit 5, converted into position data, and supplied to the stage mechanism control device 2 as a new speed command value s6.

When the stop point B is reached, the speed command value s6 becomes zero and the electric motor 3 stops.

The switch 6 closes the circuit between the speed command value s1 and the input s2 of the stage mechanism control device 2 during rehearsal, and closes the circuit between the speed command signal s6 output from the learning circuit 5 and the input s2 of the stage mechanism control device 2 during reproduction operation. Close the circuit.

By using the above structure, a result similar to the speed pattern operated during rehearsal can be obtained, and the stability of the performance is improved.

〔Effect of the invention〕

As explained above, according to the present invention, the operating state of the stage mechanism control device during rehearsal is memorized so that it can be reproduced during actual operation, so that stable effects can be achieved even when the operator's skill level is low. This makes it possible to create stage performances.
