[0039] In order to make the purpose, technical solution and beneficial effects of the present invention more clearly understood, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0040] See also Figures 1 to 3 In a first aspect, the present invention provides a shadow play system, comprising:

[0041] The shadow puppet activity module 7 comprises a trunk 2 and limbs 3 connected by the joint point 1;

[0043] The processing module stores the angle rotation information, converts the angle rotation information into an electrical signal, and sends the electrical signal to the servo driver to drive the joint point 1 to rotate.

[0044] In this embodiment, the servo motor 8 preferably adopts a brushless DC motor. The brushless motor has the advantages of small size, light weight, large output, fast response, high speed, small inertia, smooth rotation, stable torque, complex control, and easy to realize intelligentization, which meets the conditions for controlling shadow puppetry. The displacement of the servo motor 8 is controlled by a pulse signal. Every time a pulse signal is given to the servo motor 8, the servo motor 8 can output a certain displacement. When a quantitative displacement of the servo motor 8 is required, only a corresponding number of pulse signals need to be given, which is suitable for precise control of the display of shadow puppetry.

[0045] A shadow puppet character is installed on the shadow puppet movable module 7, and the joints of the shadow puppet character used for performance rotation can be connected to the joint points 1 of the shadow puppet movable module 7.

[0046] The processing module preferably uses an ATmega328P single-chip microcomputer as a core controller, designs an internal and external control communication interface of the single-chip microcomputer, reasonably allocates signal bandwidth and driving current, and drives the servo driver to drive the joint point 1 of the shadow puppet activity module 7 to rotate.

[0047] Among them, the shadow puppet performer controls the shadow puppet movable module 7 to perform the play. In order to facilitate the control of the shadow puppet performer, the joint point 1 connected to the axis can also be fixedly connected to the movable rod 4 to facilitate the control of the shadow puppet performer. When the limb 3 rotates under the drive of the joint point 1, the encoder records and stores the angle rotation information and sends the angle rotation information to the processing module. After receiving the angle rotation information, the processing module converts it into a pulse signal. When receiving the pulse signal, the servo driver accurately controls the motor to rotate, thereby achieving precise positioning, which can reach a level of 0.001mm;
