Description

Technical Field

[0001] The present invention relates to the technical field of stage lighting control, and in particular to a method for realizing stage lighting linkage synchronization control based on Bluetooth periodic broadcasting technology. Background Art

[0002] In the current field of stage light control technology, a known technical means is that the master device uses BLE legacy to broadcast light data. However, this technology has significant defects. When BLE legacy broadcasts, a random number is added to its broadcast interval, which makes it impossible to keep the broadcast interval fixed. In the application scenario of stage lights, the slave device relies on receiving the broadcast data of the master device to synchronize its own lighting actions, but due to the non-fixed broadcast interval, it is difficult for the slave device to accurately predict the reception time of the next broadcast data, and thus it is impossible to accurately synchronize the lights with the master device, which seriously affects the consistency and coordination of the overall effect of the stage lighting.

[0003] Therefore, there is an urgent need in the art for a technical solution that can solve the lighting synchronization problem between master and slave stage lighting devices.

[0004] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention

[0005] The purpose of the present invention is to provide a technical solution that can ensure that in various complex stage performance scenes, multiple stage lights can accurately and coordinately display lighting effects according to a unified rhythm and instructions.

[0006] To achieve the above object, the present invention provides the following solutions:

[0007] A method for realizing linkage and synchronous control of stage lights based on Bluetooth periodic broadcast technology, comprising:

[0008] Lighting action segmentation and numbering: The complete lighting action sequence is divided into several independent sub-actions according to the time interval of 100ms, and each sub-action is given a unique number. These numbers will serve as the key identification for subsequent communication and synchronization between master and slave devices;

[0009] When the main device starts the lighting effect display, the PA broadcast process is immediately started at a preset fixed interval of 100ms;

[0010] First, perform PA initialization and configure related broadcast parameters to ensure that the broadcast can be carried out stably and accurately;

[0011] Then, the position information of the light data to be broadcasted in the entire light action sequence is obtained. This position information is closely related to the sub-action number previously divided;

[0012] After completing the above preparations, enable the PA broadcast function and start broadcasting data packets containing the light action numbers to the surrounding space. At the same time, set a 100ms timing mechanism. Whenever the timing time is reached, the master device obtains the next light data location and broadcasts it, and repeats this cycle to continuously broadcast the entire light action sequence.

[0013] After the slave device is started, it keeps the PA receiving function on and monitors the broadcast data packets from the master device at all times.

[0014] When the slave device successfully receives the PA data, it immediately parses the data packet and extracts the light action number contained therein;

[0015] According to the received light action number and the fixed receiving interval of 100ms, the relative position relationship between its own light and the main device light is accurately calculated, so as to determine the light action it should perform and the execution time.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] The present invention uses PA technology to enable the master device to broadcast lighting data at an accurate fixed period of 100ms, and the slave device also receives and processes data based on the same fixed interval, thereby achieving accurate synchronization of the master and slave device lights. This accurate synchronization is of great significance in stage performances, and can ensure that multiple stage lights always maintain a highly consistent action rhythm in the case of complex lighting effect switching and combination, creating a shocking and coordinated stage visual effect, greatly enhancing the artistic expression and viewing of stage performances.

These numbers will serve as key identifiers for subsequent communication and synchronization between master and slave devices.

[0027] like Figure 1 As shown in the figure, after the main device starts running, it first determines whether there is new light data to be broadcast. If so, it initializes the PA, obtains the light data location, then enables the PA broadcast function to start broadcasting the light data, and starts the 100ms timing mechanism at the same time.
