| Zusammenfassung: | The utility model discloses a cigarette conveying and coding detection circuit. The device comprises two detection circuits which are connected in parallel, the input ends of the two detection circuits are respectively connected with the signal output ends of the two infrared sensors; wherein each detection circuit comprises an optical coupler, one side of a light emitter of each optical coupler is connected with a signal output end of the infrared sensor, the other side of the light emitter of each optical coupler is connected to a power supply through resistance voltage division, and a lightreceptor of each optical coupler is connected to the industrial personal computer through a switch. The beneficial effects of the utility model are that the optical coupler is used for preventing electromagnetic interference generated by circuit coupling, thereby achieving the complete electrical isolation of signals; an infrared sensor is adopted, so that passing of cigarettes on the coding conveying line can be well se |
