Voice communication helmet based on ultraviolet light

The invention discloses a voice communication helmet based on ultraviolet light, belongs to the field of communication, and aims to solve the problem that the existing ultraviolet light communication has high requirements on a signal demodulation algorithm of a receiving end, is limited by the propagation characteristics of an optical channel and possibly damages a human body. Voice messages are converted into digital electric signals through the ultraviolet single-chip microcomputer voice module; the ultraviolet FPGA driving board modulates the digital electric signal to control the ultraviolet LED to generate an ultraviolet light signal; the TIR lens refracts and focuses the ultraviolet light signal to generate a focused ultraviolet light signal; the compound paraboloid condenser collects divergent light signals and sends the light signals to the optical filter, light except the ultraviolet light wave band in the light signals is filtered out, the ultraviolet light signals are transmitted to the photomultip
