However, traditional stage equipment is usually controlled independently, and the operator needs to manage multiple device channels. When multiple devices need to be coordinated, such as a group of lifting platforms synchronously lifting, car platforms and lighting hangers, the operation is complex, and it is difficult to ensure high-precision synchronization, which may cause delay or asynchronization, affecting the performance effect and safety.

BRIEF DESCRIPTION OF DRAWINGS

[0013] Figure 1 The method flowchart of the present application is shown. DETAILED DESCRIPTION

[0014] 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

[0015] Please refer to Figure 1 As shown, this invention discloses a method for grouping control and switching of stage equipment, including the following steps: S1. Construct several independent equipment control channels; S2. Dynamically match each group of equipment control channels with the target stage equipment; S3. Based on the dynamic matching results, a visual interface is generated for each group of equipment control channels to display the basic information and operating information of the corresponding stage equipment in real time. S4. Configure equipment operation rules based on the operational requirements of stage equipment, and synchronize the equipment operation rules to the corresponding equipment control channel to generate control commands for the stage equipment; S5. Construct a stage equipment collaborative control group, add the required equipment control channels to the stage equipment collaborative control group, and control the collaborative operation of multiple groups of stage equipment through a synchronization strategy.

[0016] In step S1, each group of equipment control channels is configured with an independent embedded control module to execute control commands to the stage equipment, which avoids the risk of single point of failure of the centralized controller and improves the overall reliability and fault tolerance of the system.

[0017] The equipment control channel includes automatic control mode and manual control mode, and the mode can be switched freely.

[0018] The mode switching process is as follows: A mode switching request is triggered via a physical switch or software command. If switching to manual control mode, the local joystick or virtual controls are used to receive manual operation commands. If switching to automatic control mode, the configured equipment operation rules and a smooth transition algorithm based on the current stage equipment state are executed. The smooth transition algorithm ensures that equipment actions do not abruptly or jitter when switching from automatic to manual control mode or vice versa. For example, at the moment of switching, the difference between the current automatic target and manual operation input is calculated, and a smooth transition path is generated, greatly improving operational safety and performance smoothness.

[0019] At the same time, an instruction conflict detection mechanism is activated at the moment of mode switching, thereby freezing the output of control instructions and effectively preventing instantaneous conflicts caused by the switching of instruction sources, thus providing a security guarantee for the smooth transition of algorithm execution.

[0020] The visual interface displays basic and operational information about the stage equipment, including static, dynamic, and alarm information. Each channel corresponds to an independent display area on a large screen, and equipment status information can be transmitted based on MQTT or DDS publish / subscribe systems.

[0021] Static information includes channel name, channel number, device name, device number, and rated load; dynamic information includes real-time load value and visual progress bar, device target position and value, running speed value and direction vector diagram; alarm information includes graded alarm status indication and historical alarm log.

[0022] In step S4, the equipment operation rules include motion direction rules, speed curve rules, and collaborative triggering rules. The motion direction rules are used to define the movement direction and turning conditions of the stage equipment in automatic control mode. The speed curve rules are used to set the trapezoidal or S-shaped speed planning curve during the acceleration and deceleration process of the stage equipment. The collaborative triggering rules are used to configure the logical association conditions between the actions of the stage equipment and external events or other equipment states.

[0023] Step S5 is as follows: S51. Construct a stage equipment collaborative control group, add the required equipment control channels to the stage equipment collaborative control group, and define the synchronization type of the equipment control channels within the group, including position synchronization and speed synchronization, providing a microsecond-level time reference for all stage equipment within the group, fundamentally ensuring the timing accuracy of collaborative actions; S52. Clock synchronization of all equipment control channels within the group based on the IEEE 1588 precise time protocol; S53. Broadcast collaborative control commands to the control channels of each device in the group through the data distribution service, and use the data distribution service (DDS) to broadcast control commands efficiently and reliably (claim 7), ensuring that commands are delivered to all nodes in the group quickly and consistently; S54. Real-time monitoring of equipment status deviations within the train sets triggers a real-time synchronization compensation algorithm. This algorithm continuously monitors equipment status deviations and dynamically adjusts them, effectively suppressing accumulated errors and external interference, ensuring the stability and consistency of complex train set operations over extended periods. Step S6 involves real-time detection of spatial or logical conflicts between equipment operation rules. If a conflict is detected, the relevant equipment control channels are automatically frozen and an alarm is triggered. This proactive detection system can identify potential spatial conflicts between equipment operation rules, such as collision risks caused by intersecting equipment movement paths, or logical conflicts, such as contradictory triggering conditions or unprepared dependent equipment. Once a conflict is detected, the system automatically freezes the output commands of the relevant equipment control channels and triggers an alarm, effectively preventing equipment damage and personnel safety accidents, and significantly improving system security.

[0024] 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.
