LIGHT-GUIDE METERING DEVICE DETECTION APPARATUS AND METHOD

The present disclosure discloses a light-guide metering device detection. apparatus and, methodJ The light-guide metering device detection apparatus includes a light guide component and a controller. The controller is connected to a light-guide metering device. The controller is used for: sending a detection instruction to the light-guide metering device, so that the light- guide metering device emits light according to the detection instruction, where the light-guide metering device is in embedded fit with the light guide component before the light-guide metering device receives the detection instruction, so that the light beam emitted, by the light-guide metering device can enter~ the light guide component; and outputting a detection state of the light- guide metering device according to a sampling result, where the detection state comprises qualified and unqualified, and the sampling result is obtained, by performing, by the light-guide metering device, Analog-to-Digital sampling on the light beam returned through the light guide component.
