Description

Technical Field

[0001] The invention relates to the technical field of stage, and in particular to a movable rotating stage safety control system and method. Background Art

[0002] As people's living standards continue to improve, entertainment activities are becoming more and more abundant. Watching performances is one of the common entertainment activities. In theaters, amusement parks, venues, etc., due to the needs of performance plots, special stages are often required to achieve them. Movable rotating stages are widely favored because they can flexibly change scenes and enhance performance effects.

[0003] During stage performances, props are usually used to create a stage environment and enhance the sense of stage space, thereby enhancing the audience experience and promoting emotional resonance. In order to facilitate rapid scene changes and prop transfers, props are usually placed directly on the stage surface without being fixed to the stage surface. When props are set at the top of the stage and the stage rotates or moves, since there is no fixed connection between the props and the stage surface, the props may be displaced or tipped relative to the stage surface during the rotation or movement.

[0004] The movable rotating stage safety control system and method in the prior art are not convenient for real-time monitoring of the position of props. When the props move to the edge of the stage, the stage cannot be controlled to stop rotating in time, thereby being unable to avoid continuous movement of the props, further exposing the risk of the props falling off the stage. In addition, the weight and center of gravity height of the props are different, which will affect the stability of the props. The movable rotating stage safety control system and method in the prior art are also not convenient for adjusting the stage movement speed according to the weight and center of gravity height of the props. If the props have reached the edge of the stage and the stage movement speed is fast, the props will have the possibility of falling outside the stage and falling off the stage, which may easily injure performers, audiences or equipment, and at the same time cause damage to the props, reducing safety. Summary of the invention

[0005] The present invention provides a movable rotating stage safety control system and method. The system has the advantages that when the stage is rotating and moving, when it is detected that the props on the stage move to the edge of the stage, the stage can be controlled to stop rotating as a whole in time, thereby reducing the possibility of the props continuing to move. The stage movement speed can be adjusted to ensure that the props will not fall over, so that the stage moves at a speed closest to the stage performance requirements, thereby preventing the props from falling over on the outside of the stage and falling off the stage. When the stage is about to stop moving, the position of the props can be adjusted by rotating the outer stage, so that when the stage stops, even if the target prop falls over due to inertia, it will fall on the surface of the stage, thereby reducing the possibility of the target prop falling off the stage. The system solves the problem mentioned in the above background technology that it is not convenient to monitor the position of the props in real time and to control the rotation and movement speed of the stage according to the real-time position of the props during the stage rotation and movement, thereby making it easy for the props to fall off the stage.

[0088] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0089] For example, see Figure 1 , a movable rotating stage safety control system, comprising:

[0090] Acquisition module: acquiring prop data and target prop position, wherein the prop data includes weight, total height and center of gravity height;

[0091] Simulation training module: Based on the prop data, a control set is formed through data training strategies to train props of different weights and different relative heights of the center of gravity, and the maximum speed at which the stage can move while keeping the props from tipping over;

[0092] Position determination module: Based on the position of the target prop, the rotation control data is formed through the position determination strategy to determine whether to stop the stage from rotating;

[0093] Adjustment determination module: if the stage stops rotating, adjustment determination data is formed according to the control data through the adjustment determination strategy, so as to determine whether the stage moving speed needs to be adjusted while keeping the props from falling over;

[0094] Speed ​​control module: according to the adjustment judgment data, through the speed adjustment strategy, the speed adjustment data is formed to adjust the stage movement speed;

[0095] Rotation determination module: according to the position of the target prop, through the rotation determination strategy, the rotation determination data is formed to determine whether the position of the target prop needs to be rotated and adjusted;

[0096] Rotation control module: Based on the rotation determination data, the rotation adjustment strategy is used to form rotation adjustment data, rotate the stage, and adjust the position of the target props so that the target props will not fall off the stage when the stage stops moving.

[0097] By means of the above-mentioned movable rotating stage safety control system, during a stage performance when the stage needs to rotate and move, the position of the props on the upper end of the stage is monitored in real time. If the friction is insufficient due to the smoothness of the stage surface or the center of gravity of the prop is unstable, so that the prop moves to the warning area, the entire stage can be controlled to stop rotating, thereby reducing the possibility of the prop continuing to move, thereby reducing the risk of the prop falling from the stage; then, the weight and relative height of the center of gravity of the props on the stage are compared with the data in the reference set to obtain the maximum speed at which the stage can move while keeping the props on the stage from tipping over, and by comparing the maximum speed with the current stage movement speed, it is determined whether the stage movement speed needs to be adjusted. If the maximum speed is greater than or equal to the current stage speed, the stage movement speed is not changed; if the maximum speed is less than the current stage speed, the stage movement speed is not changed. speed, the stage movement speed is adjusted to the maximum speed, so that under the condition that the props will not fall over, the stage can be driven to move at the speed closest to the stage performance requirements, so as to avoid the props from falling over outside the stage and falling off the stage, thereby improving safety, and further determining whether the stage can reach the position required by the stage performance within the time range required by the stage performance when moving at the maximum speed. If it arrives after the time range required by the stage performance, it is necessary to further extend the other programs of the stage performance backwards so that the various programs of the stage performance can be synchronized to ensure the stage performance effect; when the stage is about to stop moving, it can determine whether the position of the props needs to be rotated and adjusted according to the position of the props on the stage, so that when the stage stops moving, even if the props fall over, they will not fall to the outside of the stage, thereby improving safety.

[0098] For example 2, please refer to Figure 2 This embodiment also provides a method for using a movable rotating stage safety control system, wherein the data training strategy specifically includes:

[0099] Obtain the weights of different props to form a weight set A, denoted as A1...An. The stability of props is related to their weight. Heavier props are more stable than lighter props. When subjected to external force, heavier props are less likely to fall over than lighter props. On the contrary, lighter props are more likely to fall over than heavier props.

[0100] Obtain the relative heights of the center of gravity of all props of different weights to form a set of relative heights of the center of gravity B, recorded as B1...Bn. The stability of the props is related to the relative height of the center of gravity of the props. The lower the relative height of the center of gravity of the props, the more stable the props are and the less likely they are to fall when subjected to external forces. Conversely, the higher the relative height of the center of gravity of the props, the more likely the props are to lose balance and fall when subjected to external forces. Therefore, when the stage performance is about to end and the stage needs to be slowed down and stopped, the props may fall under the influence of the change in stage speed, affecting safety;

[0101] Map the elements in the weight set A to the elements in the relative height set B of the center of gravity one by one to form a conditional set, denoted as A1B1, A1B2, A1Bn, AnB1, AnB2, AnBn;

[0102] Get the maximum speed corresponding to each element in the condition set to form a maximum speed set C, recorded as C1, C2, C3, C4, C5, C6, where the maximum speed is the maximum speed at which the stage can move while keeping the props from falling over;

[0103] The elements in the condition set are matched one by one with the elements in the maximum speed set C to form a comparison set, which is recorded as A1B1C1, A1B2C2, A1BnC3, AnB1C4, AnB2C5, and AnBnC6.

[0104] In this embodiment, the relative heights of the centers of gravity of all props of different weights are obtained, specifically including:

[0105] Get the total height of each prop of different weight and set it as the total height of the prop;

[0106] Obtain the center of gravity height of each prop of different weight and set it as the center of gravity height of the prop;

[0107] Calculate the relative height of the prop's center of gravity: relative height of the prop's center of gravity = total height of the prop ÷ height of the prop's center of gravity.

[0108] Embodiment 3: This embodiment is an improvement made on the basis of Embodiment 2. Specifically, the location determination strategy includes:

[0109] The stage includes an inner stage and an outer stage, such as Figure 3 As shown, the inner stage and the outer stage respectively adopt two rotating mechanisms for distributed control, and the inner stage and the outer stage can rotate synchronously or asynchronously;

[0110] The upper surface area of ​​the inner stage is defined as the safe area, and the upper surface area of ​​the outer stage is defined as the warning area. The safe area is located at the center of the upper surface of the stage, and the warning area is located near the edge of the upper surface of the stage. During the rotation and movement of the stage, when the props are in the safe area, the props will not fall from the upper surface of the stage. When the props are in the warning area, the props may fall from the upper surface of the stage.

[0111] Get the props on the stage surface and set them as target props;

[0112] Get the target prop position in real time;

[0113] When the target prop moves from the safety area to the warning area, the inner and outer stages stop rotating. During the stage rotation, the target prop may be displaced relative to the stage surface. When the target prop moves to the warning area, if the target prop continues to be displaced, there is a risk of falling off the stage. Therefore, the stage is stopped from rotating to reduce the possibility of the target prop falling.

[0114] Execute the adjustment judgment strategy. When the target prop moves to the warning area, if the target prop tips over, it may fall directly from the stage surface. Therefore, it is necessary to determine whether the current moving speed of the stage will cause the target prop to tip over. Then, determine whether the stage moving speed needs to be adjusted according to the actual situation to ensure that the target prop does not tip over during the stage movement and improve safety.

[0115] Embodiment 4: This embodiment is an improvement made on the basis of Embodiment 3. Specifically, the determination strategy is adjusted, including:

[0116] Obtain the weight and relative height of the center of gravity of the target prop, and set them as the target weight and the target relative height of the center of gravity respectively;

[0117] Obtain an element in the reference set that corresponds to both the target weight and the relative height of the target center of gravity, and define it as the target element;

[0118] Get the maximum speed under the target element and set it as the target maximum speed;

[0119] Get the current moving speed of the stage and set it as the current speed;

[0120] If the target maximum speed ≥ the current speed, it means that the current moving speed of the stage does not exceed the target maximum speed, which means that if the stage continues to move at the current speed, the props will not fall over, and the judgment will not be performed;

[0121] If the target maximum speed is less than the current speed, it means that the current moving speed of the stage exceeds the target maximum speed, which means that if the stage continues to move at the current speed, the props may topple over and fall off the surface of the stage, and the speed adjustment strategy is executed.

[0122] In this embodiment, the speed adjustment strategy specifically includes:

[0123] Get the current position of the stage and set it as the current position;

[0124] Obtain the stage moving position required for stage performance and set it as the required position;

[0125] Calculate the moving distance, moving distance = required position - current position;

[0126] Calculate the pre-movement time, which is the time required to move the stage from the current position to the required position if the stage is moved at the target maximum speed.

[0127] Get the current time;

[0128] Calculate the expected arrival time, expected arrival time = current time + expected movement duration;

[0129] Obtain the time range required for the stage performance to arrive at the required position, which is defined as the required time range and recorded as [Y1, Y2];

[0130] If the expected arrival time is ≥ time Y1, and the expected arrival time is ≤ time Y2, it means that if the stage moves at the target maximum speed, the time when it arrives at the required position is within the required time range and will not affect the overall performance effect of the stage. Then the stage movement speed is adjusted to the target maximum speed, and the rotation determination strategy is executed;

[0131] If the expected arrival time is greater than time Y2, it means that if the stage moves at the target maximum speed, the time it takes to reach the required position exceeds the required time range. Then the stage moving speed is adjusted to the target maximum speed, and the adjustment time is calculated. Adjustment time = expected arrival time - time Y2;

[0132] If the stage performance time is extended backwards by adjusting the duration, other programs of the stage performance, such as lighting, stage background images and music, need to be extended backwards so that each program of the stage performance can be synchronized to ensure the stage performance effect;

[0133] Execute the rotation decision strategy.

[0134] Embodiment 5: This embodiment is an improvement made on the basis of embodiment 4. Specifically, the rotation determination strategy includes:

[0135] Get the end position of the stage performance;

[0136] Set the judgment position, judgment position = stage performance end position - (target maximum speed × 5);

[0137] When the stage reaches the determined position, the area division strategy is executed to obtain the first area and the second area. When the stage stops moving, the target prop may fall in the direction of the stage movement due to inertia. If the target prop is located in the first area, the prop will fall to the outside of the stage when it falls in the direction of the stage movement due to inertia. If the target prop is located in the second area, the prop will fall on the surface of the stage when it falls in the direction of the stage movement due to inertia, and will not fall to the bottom of the stage, thereby improving safety. It should be noted that the division of the first area and the second area is based on the direction of the stage movement. If the stage rotates, the positions of the first area and the second area relative to the direction of the stage movement will not change with the rotation of the stage.

[0138] Get the target prop position;

[0139] If the target prop is located in the first area, it means that when the stage stops moving, the target prop may fall in the direction of the stage movement due to inertia and fall outside the stage, then the rotation adjustment strategy is executed to rotate the target prop to the second area;

[0140] If the target prop is located in the second area, it means that when the stage stops moving, the target prop may fall in the direction of the stage movement due to inertia and fall on the surface of the stage, and no judgment is performed.

[0141] In this embodiment, please refer to Figure 4 , the regional division strategy includes:

[0142] Get the stage movement direction;

[0143] The stage moving direction is set as the first target direction;

[0144] The direction opposite to the stage movement direction is defined as the second target direction;

[0145] Get all the diameters of the total area and define it as the diameter set;

[0146] Get the stage moving direction line;

[0147] Obtain the element in the diameter set that is parallel to the stage moving direction line and set it as the first target diameter;

[0148] Obtain an element in the diameter set that is perpendicular to the first target diameter and define it as the second target diameter;

[0149] Get the total height of the target prop;

[0150] Calculate the target distance, target distance = total height of target props ÷ 2;

[0151] Get the outer edge of the upper surface of the outer stage and define it as the outer edge;

[0152] Obtain two intersection points between the second target diameter and the outer edge line and define them as the first target intersection point and the second target intersection point respectively;

[0153] Draw perpendicular lines of the diameter of the second target from the intersection of the first target and the second target to the direction of the second target, which are respectively defined as the first perpendicular line and the second perpendicular line, and the lengths of the first perpendicular line and the second perpendicular line are both the target distance;

[0154] The endpoints of the first perpendicular line and the second perpendicular line away from the second target diameter are respectively defined as the first target endpoint and the second target endpoint;

[0155] connecting the first target endpoint and the second target endpoint to form a first connection line;

[0156] Get the center point of the upper surface of the inner stage and set it as the target center point;

[0157] The first connecting line is used as a dividing line to divide the warning area into a first area and a second area, wherein the second area is located in a second target direction of the target center point.

[0158] In this embodiment, please refer to Figure 5 , rotation adjustment strategy, including:

[0159] Get the target prop position;

[0160] Connect the target prop position and the target center point to form a second connecting line;

[0161] Obtaining the angle between the second connecting line and the first connecting line as the target angle;

[0162] The inner stage remains stationary, and the outer stage is rotated at a target angle, thereby moving the target prop to the second area position, so that when the stage stops, even if the target prop topples due to inertia, the target prop will fall on the stage surface instead of the stage outer side, thereby reducing the possibility of the target prop falling from the stage and improving safety; during the stage performance, when the stage needs to be rotated, the inner stage and the outer stage are rotated synchronously, and when the stage is about to stop moving and the position of the target prop needs to be adjusted, the inner stage remains stationary and the outer stage is rotated, so as to avoid affecting the performers at the upper end of the inner stage during the process of adjusting the position of the target prop by rotation, thereby ensuring the performance effect and safety of the performers.

[0163] The embodiment of the present disclosure also provides a non-transitory computer-readable storage medium, which stores computer instructions, and the computer instructions are used to enable the computer to execute the movable revolving stage safety control system and method in the aforementioned method embodiment.

[0164] It should be noted that more specific examples of computer-readable storage media may include portable computer disks, hard disks, erasable programmable read-only memories (EPROMs or flash memories), optical storage devices, magnetic storage devices, or any suitable combination thereof.
