BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a simulation method for stage mechanisms.

2. Description of the Related Art Theaters these days are not only used for plays and plays, but are also increasingly used for multiple purposes such as concerts and operas. Furthermore, with the diversification of stages, there is a need for equipment that can produce innovative and bold production effects.

[0003] For this reason, stage mechanisms have been developed in which hanging mechanisms and floor mechanisms in theaters, halls, etc. are driven by power, and these mechanisms are comprehensively controlled by a computer.

[0004] In this type of new stage mechanism, a computer controls the hanging mechanism to hang curtains, curtains, decorations, etc.
In addition to automatically lowering and lifting large props, etc. onto the stage, the floor mechanism can be controlled to automatically raise and lower actors and props, etc., move them in and out from the stage, and rotate the stage. It can be rotated with.

[0005] Therefore, with a computer-controlled stage mechanism, scene settings can be easily changed depending on the type of performance, and scene changes during a performance can be automatically controlled. For example, during a theatrical performance, if there is a need to change scenes from one scene to the next,
The operations of the hanging mechanism and floor mechanism between such scenes are recorded in advance on a computer, and during the actual performance, the data is read out from the computer in sequence and the hanging mechanism and floor mechanism are operated to automatically change scenes. can be achieved. Furthermore,
Even when a hanging mechanism or a floor mechanism is operated in order to obtain a special performance effect during a certain scene, these operations can be stored in advance in a computer and reproduced later. In this way, ``scene operation'', in which the operations of the hanging mechanism and floor mechanism are stored in advance in a computer for each scene, read out in sequence, and then operated automatically, is ideal for large-scale stages in large-scale theaters. There is an advantage that even a mechanism can be controlled reliably.

[0006] Therefore, an operation control device for a stage mechanism generally consists of a computer, an operation console, and a control panel. FIG. 7 shows an example of the configuration of this type of operation control device.

In the figure, the main console 2 is connected to the computer 1 and has a CRT 4A for setting, a CRT 4B for operation,
A keyboard 5 and a controller 6 for operation settings are installed. By operating the keyboard 5 while viewing the setting CRT 4A, the operating data can be stored in the memory of the computer 1. Further, during operation, the operation data of the computer 1 can be transferred to the operation setting controller 6 of the main console 2 at any time for operation.

[0008] The control panel 3 includes a large number of control devices such as motors (
drive device) 13 is connected. These drive devices 13
This operates floor mechanisms such as the main stage approach, revolving stage, and sliding wagon, as well as hanging mechanisms such as stage curtains, curtains, props, and lighting.

In order to comprehensively control the operation of such a floor mechanism and hanging mechanism, the control panel 3 is connected to a master controller 8.
, a monitoring controller 9, a plurality of operation control controllers 10, a control device 12, and the like.

Further, a manual operation setting controller 15 is installed on the manual operation console 14 to enable manual operation.

The above-described operation setting controller 6 of the main console 2, master controller 8 of the control panel 3, etc. are programmable sequencers that sequentially execute commands from the computer 1, and are in a superior-lower relationship.

A double high-speed optical network 7 is connected between the operation setting controller 6 of the main console 2 and the master controller 8 and monitoring controller 9 of the control panel 3.
The other controllers, including those between them, are connected by an electrical high-speed data transmission network 11.

In the above configuration, when setting a scene operation, the number of the equipment to be operated is displayed on the setting CRT 4A, and operation data consisting of the operating range and operating speed of the equipment is input using the keyboard 5. and store the contents in the memory of the computer 1.

During a performance of scene operation, when a scene number is input, the set equipment and its operation data are read out from the memory of the computer 1 according to the scene number, and the operation setting controller 6 of the main console 2 is read out. The data arrangement is changed using the control panel 3 as operation data for each device.
output to the master controller 8. The master controller 8 rearranges the input operation data of each device, and gives commands from the control device 12 to the drive device 13 via the corresponding operation control controller 10. Changing the data arrangement is to change the operational data into a format suitable for each piece of hardware.

[0015] Further, manual operation is for checking and correcting the speed and stop position of the hanging mechanism and floor mechanism during stage exercise and preparation operation. Accordingly, the manual operation setting controller 15 outputs the operation data to the corresponding operation control controller 10, and the drive device 13 is operated via the control device 12.

[0016] When operating the stage mechanism described above, it is important to pay attention to safety. Conventionally, each tool was actually decorated on the hanging mechanism or floor mechanism, and a human being could see this and prevent the tools from interfering with each other. I visually confirmed that it did not.

[0017]

[Problems to be Solved by the Invention] However, visually checking the interference of tools is troublesome, and since it is necessary to actually operate the stage mechanism, it takes a long time and costs to check the interference.

SUMMARY OF THE INVENTION In view of the above-mentioned problems, it is an object of the present invention to provide a stage mechanism simulation method that can check for interference between tools without actually operating the stage mechanism.

[0019]

[Means for Solving the Problems] The configuration of the stage mechanism simulation system according to the present invention includes data on the shape and position of each tool decorated on the stage mechanism, and operation data of each mechanism in the stage mechanism on which each tool is decorated. is set as input data, the position data of the tool that changes over time is calculated from the position data of the tool and the operation data for each unit time, and the position data of the tool that changes over time is calculated for each unit time from the shape data of each tool and the calculated position data. The feature is that the presence or absence of interference between tools is determined by calculation.

[0020]

[Operation] Without actually operating the stage mechanism, the stage mechanism is operated computationally to determine the momentary position of the tools and determine whether or not there will be interference.

[0021]

DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows the hardware configuration of a simulation device that realizes the present invention, and this device utilizes the computer 1, CRT 4A, and keyboard 5 of the operation control device shown in FIG. 7, and adds a variable reference time generator 16 to these. It is configured as follows. Note that 17 is a memory of the computer 1, 18 is a cue (scene start trigger) generator, 19 is a bus line, and 20 and 21 are interfaces. As the cue generator 18, one provided on the main console 2 (not shown) was used.

FIG. 2 is a functional block diagram of the simulation device, in which the data setter 22 corresponds to the keyboard 5 and CRT 4A, and each data storage section 17A
-17G are set in the memory 17, and each of the check sections 1A to 1C and the output section 1D are made to function in the computer 1 by software.

In FIG. 2, scene setting data storage section 1
7A, the operation data of the hanging object mechanism in the scene operation is inputted from the data setter 22 and set for each scene number. In addition, in the hanging object data storage section 17B, tools to be decorated on the hanging object mechanism for each scene number, that is, hanging object data (dimensions, position relative to the hanging object mechanism, weight, etc.) are stored in the data setting device 2.
It is input and set from step 2. Equipment data storage section 17C
Equipment data such as the layout of the entire stage mechanism including the hanging mechanism and floor mechanism and the capacity (allowable weight, etc.) of each piece of equipment are input from the data setting device 22 and set. Furthermore,
In the scene setting data storage section 17D, the operation data of the floor mechanism in the scene operation is stored in the data setter 22 for each scene number.
It is input and set from. Also, the figurine data storage section 17
E contains data on tools, that is, ornaments, to be decorated on the floor mechanism by scene number (dimensions, position relative to the floor mechanism, weight, etc.)
is input from the data setter 22 and set.

The checking unit 1A simulates the independent operation of the hanging object mechanism, checks whether there is interference between the hanging objects (interference check) and whether the weight and balance of the hanging objects are good or not (capacity check), and records the results as data. It is displayed on the CRT of the setting device 22 and stored in the data storage section 17F. In addition, the checking unit 1B simulates the independent operation of the floor mechanism to check whether there is interference between the ornaments (interference check) and whether the weight and balance of the ornaments are good or not (capacity check), and sends the results to the data setting device 22. Display on CRT, and data storage section 17
Store in G. Furthermore, the checking unit 1C simulates the simultaneous operation of the hanging object mechanism and the floor mechanism using the time axis of the reference time generator 18, checks for the presence or absence of interference between the hanging object and the ornament, and uses the results as hanging object data. The data is stored in the storage section 17F and the figurine data storage section 17G, and is displayed on the CRT of the data setting device 22 through the output section 1D. In addition, when the data setting device 22 receives a check result such as occurrence of interference or overcapacity from each of the checking sections 1A to 1C, it is possible to reset the operation data, hanging object, and ornament data and check the data again. Therefore, ultimately the data storage section 17F
, 17G store all data without interference.

Although not shown in FIG. 2, the computer 1

4A, and has a function to visualize and display these movements during the simulation.

FIG. 3 shows the procedure for setting data regarding the hanging object mechanism. First, the operator inputs the operating data of the hanging object mechanism by scene number (S1), and stores the operating data (
S2), after completing this (S3), input the hanging object data (S4), store this (S5), and after completing (S6),
Equipment data for the stage mechanism is input (S7) and stored (S8). After completing these steps (S9), the correspondence between the hanging object and the equipment in the hanging object mechanism that decorates it is inputted as allocation data for each scene number (S10), and this is stored in the scene setting data storage section 17A and the hanging object data storage section. The data is stored in the section 17B (S11), and the process ends (S12). The procedure for setting data regarding the floor mechanism is the same as that shown in FIG. 3, except that the hanging object mechanism is replaced with the floor mechanism, and the hanging object is replaced with the ornament.

FIG. 4 shows the procedure of interference check and capacity check in the independent operation of the hanging mechanism, and
When a scene number is set from the keyboard (S1), the computer 1 stores the allocation data for the set scene number in the scene setting data storage section 17A and the hanging object data storage section 1.
7B (S2), and equipment data (S2).
3). Next, the operation is calculated based on the operation data, hanging object data, and equipment data for this scene number,
Calculate the position data of the hanging objects as they move over time, and use this position data and shape data to determine whether the hanging objects will interfere with each other, whether the hanging objects will interfere with the hanging object mechanism, and whether the hanging objects will interfere with the hanging object mechanism. It is checked by calculation whether the permissible lifting weight of the mechanism is exceeded and whether imbalance occurs during lifting (S4). If there is a problem in this check, the information is output to the data setting device 22 and data storage section 17F (S5, S6
), if there is a problem, the process waits for the input of the next scene number (S7), and performs the same simulation for all scene numbers. Note that the checking procedure for the independent operation of the floor mechanism is also the same as that shown in FIG. 4.

FIGS. 5 and 6 show a procedure for checking mutual interference in simultaneous operation of the hanging mechanism and floor mechanism. First, as a condition setting in FIG. 5, the range of scene numbers to be simulated and the interval (clock pulse period) T0 of the reference time pulse of the variable reference time generator 16 are set (S1
), the allocation data is read out from the scene setting data storage sections 17A, 17D for all the scene numbers in the set range (S2), and the equipment data is also read out (S3).

Next, it is determined whether a cue has been issued from the cue generator 18 by the operator's operation (S4);
When a cue is issued, it is determined whether the scene starts for the hanging object mechanism or the scene for the floor mechanism (cue type) (S5), and depending on the determination result, the hanging object data or figurine data is read out (S6, S7).
), since the simulation has now started, a flag indicating that the simulation is in progress is set (S8). If it is determined in S4 that no queue has appeared, it is determined whether or not simulation is currently in progress (S9), and if not, the process returns to S4 and waits for a queue.

When the simulation flag is set, as shown in FIG. 6, it is determined whether the first pulse of the reference time pulse has occurred (S10), and if not, the variable reference time generator 16 Generate a time pulse train (S11
). Then, it is determined whether the reference time pulse is the same as the previous pulse (S12), and if it is the same, there is no meaning, so FIG.
Return to S4. If not, the suspended object,
Each position data of the ornament is calculated and obtained, and interference checks are performed between the hanging object and the ornament, between the hanging object and the floor mechanism, and between the ornament and the hanging object mechanism from each position data, dimension data, and equipment data (S13
). If there is interference, output interference occurrence information (S14, S
15). If there is no interference, the position data of each device of the stage mechanism is updated based on the operation data by an amount corresponding to one reference time pulse interval (S16), and then the state of the stage mechanism at this time is displayed as an image ( S17), and the simulation continues by returning to S4 of FIG. 5 until the position of each device of the stage mechanism reaches the target position determined by the scene number range setting (S18).
