Vehicle-mounted optical sensor provided with photosensitive element and used for observing belt materials

Abstract

The invention discloses a vehicle-mounted optical sensor provided with a photosensitive element and used for observing belt materials, and belongs to the field of device improvement technologies of an automobile electronic system. The vehicle-mounted optical sensor comprises a lens, a measuring dial, a reading dial and the photosensitive element, wherein one end of the measuring dial is connected with the lens through a micro threaded rod, the other end of the measuring dial is connected with the reading dial through a transparent center hole, center holes of the lens, the measuring dial and the reading dial are located on the same straight line, an upper covering plate and a lower covering plate are arranged on the measuring dial, the photosensitive element is a silicon element, and switching converter circuits and an integrated photosensitive element are arranged inside the photosensitive element and are used for controlling the photosensitive element to be switched on or off. Compared with the prior art, the space occupied by the photosensitive sensor is minimized, high-voltage insulation among all stages of circuits is achieved, a measuring device provided with the reading dial enables counting and measurement to be more accurate, the direction and the radiation intensity of sunlight can be accurately sensed, and the photosensitive silicon element enables the sensor to more accurately calibrate positions among the circuits.

[0002] The perfect car computer-controlled air-conditioning system can automatically adjust the temperature, humidity, cleanliness, style and wind direction of the air in the car, providing passengers with a good riding environment and ensuring that passengers are in a different environment under different external climates and conditions. In a comfortable air environment, colleagues can also detect faults. The existing on-board computer detection system is exposed to external sunlight and the environment in the car changes. It is necessary to adjust the temperature and humidity in the car in time to ensure a comfortable environment in the car. The role of the sunlight sensor is to detect the radiation intensity of the sun outside the car. The existing sunlight sensor has a narrow photosensitive element and cannot accurately calibrate the relationship between the circuits, thus affecting the system's ability to perceive the intensity and direction of sunlight.
