Abstract:
    The invention discloses a system for testing the festival decoration lamp set automatic fraction collector. The system uses the ARM main chip as the core, which connects individually with the power circuit, crystal vibrating circuit, reset circuit, data memory circuit, program memory circuit, keyboard circuit, liquid crystal display circuit, E2PROM data storage circuit, out I/O driving circuit and analogue/digital conversion circuit. The festival decoration lamp shines through connecting with the constant-current source circuit, and the light from the lamp shins on the photo-sensor to produce voltage signal, the signal will be enlarged through the signal amplification circuit, then connected with the analogue/digital conversion circuit to sample the light flux, the filament internal resistance value will be sampled through the analogue/digital conversion circuit. The system tests the light flux when the festival decoration lamp shines in the capacity rating and tests the operating resistance in low voltage, then outputs them individually according to the sorting parameter.
