Abstract
The utility model is suitable for the field of sensor measurement, and provides a system for testing a vehicle-mounted light sensor. The system comprises an adjustable light source, an illuminance switching device, a signal conversion module, and a detection and adjustment device. After the adjustable light source outputs an optical signal, an optical signal with the corresponding irradiance is outputted through controlling the switching of the illuminance switching device. After a to-be-tested light sensor receives the illumination, an analog voltage signal is outputted. The signal conversion module amplifies the analog voltage signal and converts the analog voltage signal into a digital voltage signal. After receiving the digital voltage signal, the detection and adjustment device judges whether the digital voltage signal is in a voltage range corresponding to the current irradiance or not. When all voltages at all the irradiance levels are in a preset range of voltage, a vehicle-mounted light sensor which is tested currently is affirmed to be qualified. The system provided by the utility model is simple in structure, is convenient in testing, and can be widely used for the quality testing of vehicle-mounted light sensors.
