Abstract

The component, principles as well as practical applications for photoelectric encoding transmission system are described in detail. The infrared LED and corresponding JR receiver were used in the system to realize E-O and O-E transformation. The inspected data are transmitted by JR-LED after being converted and encoded to serial signals. The infrared modulated light which is obtained by JR receiver are decoded and converted to the original electric signals. Thereby, air-isolated photoelectric data transmission comes true. Signals are picked up with 8098 single-chip microcomputer, then transmitted to the computer via R5232 for further processing. Test results are reported which were obtained from the dynamic parameter measurement of catenary and pantograph system in electrified railway.
