Description

DETAILED DESCRIPTION OF THE INVENTION [Object of the Invention] (Industrial application field) The present invention relates to a stage mechanism control device for controlling stage mechanism equipment having a suspension mechanism and a floor mechanism, and in particular, stabilization and effects of production. The present invention relates to a stage mechanism control device capable of significantly improving the performance.

(Prior Art) In general, stage mechanism equipment is provided with a suspending mechanism and a floor mechanism, and operating articles for operating the moving speed and the moving position of the suspending mechanism and the floor mechanism.
The operator operates the action desired by the director by manual operation. In addition, these effects are rehearsed in advance, and the operator must perform the operation with familiarity with the operation desired by the director.

However, since the production work by the hanging mechanism and the floor mechanism in the conventional stage mechanism equipment is left to the operator as described above, the effect of the production is not stable due to the difference in the skill of the operator, and is always stable. It is difficult to secure such a production.

(Problems to be Solved by the Invention) As described above, in the related art, there has been a problem that the effect of a stable effect cannot be secured.

SUMMARY OF THE INVENTION An object of the present invention is to provide a stage mechanism control device capable of stabilizing effects and significantly improving effects.

[Structure of the Invention] (Means for Solving the Problems) In order to achieve the above object, according to the present invention, a speed command value is set in a stage mechanism control device that controls stage mechanism equipment including a suspension mechanism and a floor mechanism. Speed setting means for outputting, speed detecting means for detecting the moving speed of the stage mechanism and outputting a speed feedback signal, and a stage mechanism controller for controlling the moving speed of the stage mechanism based on the speed command value and the speed feedback signal. At the time of rehearsal, the operation state of the stage mechanism is detected as a change in acceleration from the start position to the stop position of the operation state, and a speed feedback signal at the change point is converted into distance data from the start position. A learning function that sequentially stores the distance data and the speed command value at the change point in association with each other, and adjusts the initial operation position to the start position at the time of rehearsal during the reproduction operation. A speed command value calculated from the stored value at that time, are constituted by a learning means with a reproduction operation function of providing this to set construction controller in place of the speed command value from the speed setting means.

(Operation) Therefore, in the stage mechanism control device of the present invention, at the time of rehearsal, for example, when the approaching mechanism is to be raised at a certain speed pattern, the change in acceleration from the start position of the operation to the stop position is performed. Is detected, the speed feedback signal at that time is converted into distance data based on the position of the change point, and this distance data is sequentially stored in the learning means in association with the speed command value at that time. On the other hand, at the time of reproduction operation, the initial operation position of the approaching mechanism is adjusted to the start position at the time of rehearsal, and the speed command value at that time is obtained from the stored value, which is used instead of the speed command value from the speed setting means to control the stage mechanism. Given to the vessel. Thereby, when the user wants to execute a predetermined moving operation, the distance data and the speed command value of the moving operation are learned for each change point of the acceleration only for the first time.
After the second time, a predetermined moving operation can be easily and reliably reproduced based on the learning result. That is, at the time of the reproducing operation, the same result as that of the speed pattern operated at the time of the rehearsal is reproduced, and the stabilization of the effect and the effect can be improved.

Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 is a block diagram showing a configuration example of a stage mechanism control device according to the present invention. As shown in the drawing, the stage mechanism control device of this embodiment includes a speed setting device 1 as speed setting means, a pulse generator 2 as speed detection means, a stage mechanism controller 3, and a learning circuit 4 as learning means. , Switch 5.

Here, the speed setting device 1 outputs a speed command value S1. The pulse generator 2 detects a moving speed of a hanging mechanism and a floor mechanism, which are stage mechanisms, that is, a rotation speed of the electric motor 6 for driving these mechanisms, and outputs a speed feedback signal S2. Further, the stage mechanism controller 3 outputs a control signal S3 for controlling the moving speed of the stage mechanism, that is, the rotation speed of the electric motor 6, based on the speed command value S1 and the speed feedback signal S2.

On the other hand, the switch 5 has a contact 5A that closes during rehearsal,
It consists of a contact 5B that closes during the reproduction operation, and can be switched manually or automatically. Learning circuit 4
During the rehearsal, the operating state of the suspension mechanism and the floor mechanism as the stage mechanism is detected by detecting a change in acceleration from the start position to the stop position of the operating state, and the speed feedback signal S2 at the change point is detected. Is converted into distance data from the start position, the distance data and the speed command value S1 at the change point are associated with each other and sequentially stored in the function generator, and during the reproduction operation, the initial operation position is rehearsed. According to the starting position of the hour,
The speed command value S4 at that time is obtained from the stored value, and the speed command value S4 is provided to the stage mechanism controller 3 in place of the speed command value S1 from the speed setting device 1, and a reproducing operation function is provided.

Next, the operation of the stage mechanism control device configured as described above will be described.

First, at the time of rehearsal, the contact 5A of the switch 5 is closed and the contact 5B is open. As a result, the stage mechanism controller 3 outputs a control signal S3 based on the speed command value S1 from the speed setter 1 and the speed feedback signal S2 from the pulse generator 2, and the rotation of the motor 6 for driving the stage mechanism. The speed is controlled to be the speed command value S1. At this time, the learning circuit 4 also supplies the speed command value S1
And the speed feedback signal S2 from the pulse generator 2 are input, and the speed feedback signal S2 is integrated in the learning circuit 4 and converted into distance data. In this case, the change amount of the converted distance data is, for each change point of the acceleration, the distance data at this time and the corresponding speed command value S1 are sequentially stored in the function generator. The operation state of the floor mechanism or the like is stored for a period from the start position to the stop position of the operation state. Fig. 2
FIG. 5 is a diagram illustrating an example of a certain speed pattern stored in a function generator in a learning circuit, wherein a vertical axis V indicates a speed command value S1, and an inflection point of the speed command value S1 corresponds to a change point of acceleration. I have. In this case, it is a speed pattern at the time of moving from the operation start position A to the stop position B, and speed command values S1 at a plurality of positions from the operation start position A to the stop position B are stored. The speed command value S1 between the stored positions is linearly interpolated.

On the other hand, during the reproduction operation, the contact 5B of the switch 5 closes and the contact 5A opens. Then, the initial operation position is adjusted to the operation start position A at the time of rehearsal, and the speed command value S4 at that time is obtained from the stored value of the function generator in the learning circuit 4, and this is replaced with the speed command value S1 from the speed setting device 1. Then, it is provided to the stage mechanism controller 3 through the contact 5B. As a result, the control signal 3 is output from the stage mechanism controller 3 based on the speed command value S4 and the speed feedback signal S2 from the pulse generator 2, and the rotation speed of the electric motor 6 driving the stage mechanism is changed to the speed command value. Controlled to be S4. As a result, the stage mechanism moves, and the speed feedback signal S2 from the pulse generator 2 is input to the learning circuit 4 and converted into distance data in the same manner as described above.
It is given to the stage mechanism controller 3 as S4. Finally, the vehicle reaches the stop position B, the speed command value S4 becomes "0", and the electric motor 6 stops. Thereby, at the time of the reproduction operation, the same result as the speed pattern operated at the time of the rehearsal is reproduced, and the stabilization of the effect and the effect can be improved.

As described above, in the present embodiment, a stage mechanism control device that controls stage mechanism equipment including a suspension mechanism and a floor mechanism includes:
A speed setter 1 for outputting a speed command value S1, a pulse generator 2 for detecting a rotation speed of an electric motor 6 for driving a stage mechanism such as a suspension mechanism and a floor mechanism and outputting a speed feedback signal S2; A control signal S3 for controlling the rotation speed of the electric motor 6 based on the command value S1 and the speed feedback signal S2.
Stage mechanism controller 3 for outputting a signal, and a switch 5 for manually or automatically switching between rehearsal and reproduction operation
At the time of rehearsal, the operation state of the suspension mechanism and the floor mechanism, which are stage mechanisms, is determined by detecting a change in acceleration from the start position A to the stop position B of the operation state, and determining the position of the change point. The speed feedback signal S2 at that time is converted into distance data as a reference, and this distance data is used as the speed command value at that time.
A learning function that sequentially stores in the function generator in association with S1, and in the case of reproduction operation, the initial operation position is set to the start position A at the time of rehearsal, the speed command value S4 at that time is obtained from the stored value, and this is set as the speed setting. And a learning circuit 4 having a reproduction operation function to be given to the stage mechanism controller 3 in place of the speed command value S1 from the device 1.

Therefore, the best operation state at the time of rehearsal is sequentially stored in the function generator in the learning circuit 4 with distance data and speed at the time of acceleration change of the operation of the electric motor 6 for driving the suspension mechanism, the floor mechanism, and the like. A result similar to the operated speed pattern can be reproduced. This makes it possible to stabilize the performance by the hanging mechanism and the floor mechanism and to significantly improve the effect.
