Active/passive dual-mode induction high-voltage electrified display device

The utility model relates to an active/passive dual-mode induction high-voltage electrified display device. The active/passive dual-mode induction high-voltage electrified display device comprises a non-contact type high-voltage electrified sensor, wherein an output end of the non-contact type high-voltage electrified sensor is connected with a trigger circuit through a rectifying bridge and an energy storage circuit in sequence; one path of an output end of the trigger circuit is connected to a passive channel through a distribution circuit, and the other path is connected to an active channel; the passive channel comprises a first LED lamp and a first optocoupler; a positive electrode of the first LED lamp is connected with a first output end of the distribution circuit; a negative electrode of the first LED lamp is connected with a positive input end of the first optocoupler; a negative input end of the first optocoupler is connected with a negative end of the rectifying bridge; and in the active channel, a signal output by a second output end of the distribution circuit passes through a second optocoupler and is reshaped and then sent to a CPU processor for processing and output display.
