Description

Technical Field

[0001] This invention relates to the field of stage automation technology, and more specifically to a control method for a configurable joystick for stage equipment. Background Technology

[0002] In stage performance control systems, physical joysticks are the core human-computer interaction devices for controlling lighting, sound, and mechanical stage equipment. Traditional stage control consoles typically use a fixed mapping method for joysticks, meaning each joystick can only control a single device or a fixed group, lacking a flexible dynamic allocation mechanism. During actual performances, operators often need to switch between controlling different devices or combinations of devices according to the needs of the performance. Existing technical solutions often require manually switching control channels or using multiple dedicated joysticks, resulting in a complex operating interface, delayed response, and susceptibility to errors.

[0003] Furthermore, traditional joysticks lack the ability to adapt to the characteristics of the controlled equipment. Different stage equipment (such as lifting stages, moving lights, and rotating machinery) have vastly different dynamic characteristics and load states. However, traditional joysticks use uniform force feedback parameters and dead zone settings, which cannot provide an operating feel that matches the real-time state of the equipment. This seriously affects the control accuracy and operator experience, especially when controlling high-inertia or precision equipment. Operators find it difficult to perceive the actual load state of the equipment through the joystick, which can easily lead to overshoot or response lag. Summary of the Invention

[0004] The purpose of this invention is to provide a control method for a configurable joystick for stage equipment to solve the above-mentioned problems.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A control method for a configurable joystick for stage equipment includes the following steps: S1. Based on the stage control interface, the control of the physical joystick is dynamically allocated to a single stage device or a predefined device group consisting of multiple stage devices. S2. Based on the assigned target, automatically load the corresponding control mapping rules and joystick behavior configuration; S3. Based on the device type and real-time load of the assigned target, the force feedback intensity, dead zone size and travel damping of the physical joystick are adaptively and dynamically adjusted to provide a matching device operation feel. S4. The analog signals generated by manipulating the physical joystick are sampled by a high-precision ADC and converted into control commands; S5. The control command is issued through the device control channel to drive a single target device or a group of target devices to move smoothly along an S-shaped speed curve, and the real-time status data of the device and the control information of the joystick are updated to the global status data model for synchronous display on all consoles.

[0006] Preferably, the control assignment operation of the physical joystick in step S1 is completed by dragging the graphical joystick icon onto a single target device or a group icon of target devices, and the assignment result is displayed in real time on the stage control interface, which includes the target name, number and current control mode.

[0007] Preferably, step S2 specifically includes: When assigned to a single stage device, the physical joystick's axes are directly mapped to the device's speed or position in the corresponding degree of freedom. When assigned to a stage equipment group, each axis of the physical joystick is mapped to the movement of the virtual master device controlling the overall movement of the group in the corresponding degree of freedom, and each slave device in the group follows the movement according to predefined synchronization rules.

[0008] Preferably, the adaptive dynamic adjustment of the physical joystick in step S3 specifically involves: acquiring the dynamic parameters of the target device, calculating the maximum operating torque and setting it as the upper limit of the force feedback intensity of the physical joystick, and simultaneously, adjusting the feedback force proportionally to simulate the device load feeling based on the real-time load rate of the target device.

[0009] Preferably, in step S5, before the control command is sent through the equipment control channel, it undergoes a nonlinear filtering process to convert the operator's sudden and violent manipulation input into a smooth, continuous control command constrained by acceleration, and then drives the equipment to run.

[0010] Preferably, the global state data model maintains a virtual object for the physical joystick, which records its control holder, current allocation target, force feedback parameters, and operation log in real time. The state of the physical joystick can be viewed in real time from any console.

[0011] Preferably, the control of the physical joystick is transferred between different operators through an access token mechanism. When the receiving operator gains control, the physical joystick automatically inherits the control target and corresponding force feedback configuration assigned by the previous operator, thereby achieving seamless switching of control context.

[0012] Preferably, the physical joystick integrates a biometric identification sensor, and when the control of the physical joystick is transferred, the biometric characteristics of the receiving operator must be verified. Only after the verification is successful can the permission token complete the ownership change registration on the blockchain network.

[0013] Preferably, the physical joystick behavior configuration supports mode switching, allowing its output mode to be switched between speed control mode and position control mode.

[0014] By adopting the above technical solution, the present invention has the following advantages compared with the prior art: 1. This invention provides a control method for assignable joysticks on stage equipment. Through a dynamic allocation mechanism, a single physical joystick can be flexibly assigned to any single device or a predefined group of devices, significantly reducing the number of joysticks required for the control console and simplifying the operation interface. Operators can complete the allocation of control rights through an intuitive graphical interface, significantly improving the response speed and operational efficiency of equipment switching during performances.

[0015] 2. This invention provides a control method for a configurable joystick for stage equipment. By adaptively adjusting the force feedback intensity, dead zone size, and stroke damping, the joystick operation feel is precisely matched with the dynamic characteristics and real-time load status of the target equipment. The operator can directly perceive the load changes of the equipment through the joystick, achieving more precise control and reducing overshoot and response lag. It is particularly suitable for high-precision equipment control scenarios.

[0016] 3. This invention provides a control method for a configurable joystick for stage equipment. It employs a high-precision ADC sampling combined with an S-shaped velocity curve control algorithm to convert the operation input into a smooth, continuous control command constrained by jerk. This effectively avoids the impact and vibration during the start-up and shutdown phases of the equipment, extends the service life of the equipment, and enhances the artistic expressiveness of stage movements.

[0017] 4. This invention provides a control method for a scalable joystick for stage equipment. Through virtual mapping and synchronization rules of equipment grouping, it realizes coordinated motion control of multiple devices within the group, ensuring motion consistency. Combined with a global state data model, it displays the equipment status and control ownership information in real time, providing a clear state perception for multi-operator collaborative work and avoiding control conflicts.

[0019] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the invention. Example

[0020] Please refer to Figure 1 As shown, this invention discloses a control method for a configurable joystick for stage equipment, comprising the following steps: S1. Based on the stage control interface, the control of the physical joystick is dynamically allocated to a single stage device or a predefined device group consisting of multiple stage devices. S2. Based on the assigned target, automatically load the corresponding control mapping rules and joystick behavior configuration; S3. Based on the device type and real-time load of the assigned target, the force feedback intensity, dead zone size and travel damping of the physical joystick are adaptively and dynamically adjusted to provide a matching device operation feel. S4. The analog signals generated by manipulating the physical joystick are sampled by a high-precision ADC and converted into control commands; S5. Control commands are issued through the device control channel to drive a single target device or a group of target devices to move smoothly along an S-shaped speed curve, and the real-time status data of the device and the control information of the joystick are updated to the global status data model for synchronous display on all consoles.

[0021] In step S1, the control assignment of the physical joystick is completed by dragging the graphical joystick icon onto a single target device or a group icon of target devices, and the assignment result is displayed in real time on the stage control interface, including the target name, number and current control mode.

[0022] Step S2 is as follows: When assigned to a single stage device, the physical joystick's axes are directly mapped to the device's speed or position in the corresponding degree of freedom. When assigned to a stage equipment group, each axis of the physical joystick is mapped to the movement of the virtual master device controlling the overall movement of the group in the corresponding degree of freedom, and each slave device in the group follows the movement according to predefined synchronization rules.

[0023] The adaptive dynamic adjustment of the physical joystick in step S3 is as follows: obtain the dynamic parameters of the target device, calculate the maximum operating torque and set it as the upper limit of the force feedback intensity of the physical joystick. At the same time, according to the real-time load rate of the target device, adjust the feedback force proportionally to simulate the load feeling of the device.

[0024] In step S5, before the control command is sent through the equipment control channel, it undergoes a nonlinear filtering process to convert the operator's sudden and violent manipulation input into a smooth, continuous control command constrained by acceleration, and then drives the equipment to run. This eliminates any potential sudden and violent input and ensures a smooth transition of the start-up acceleration.

[0025] The global state data model maintains a virtual object for the physical joystick, which records its control holder, current assignment target, force feedback parameters, and operation logs in real time. The state of the physical joystick can be viewed in real time from any console.

[0026] Control of the physical joystick is transferred between different operators via a permission token mechanism. When the receiving operator gains control, the physical joystick automatically inherits the control objectives and corresponding force feedback configuration assigned by the previous operator, achieving seamless switching of control contexts. This permission token mechanism ensures a secure transfer of control between different operators and automatically inherits the control objectives and force feedback configuration of the previous operator, guaranteeing seamless switching of control contexts. It is particularly suitable for scenarios requiring multi-operator relay control in large-scale performances.

[0027] The physical joystick integrates a biometric sensor, and when the control of the physical joystick is transferred, the biometric characteristics of the receiving operator must be verified. Only after the verification is successful can the permission token complete the ownership change registration on the blockchain network.

[0028] The physical joystick behavior configuration supports mode switching, allowing users to switch its output mode to speed control mode or position control mode.

[0029] The above are merely preferred embodiments of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the scope of the technology disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
