Background
The light-sensing probe, such as an infrared sensing probe, has the advantages of simple and flexible structure, small volume, light weight, low cost and no special requirement on environment, and is widely applied to bathroom products such as intelligent sensing faucets, intelligent urinals and the like. The existing light sensing probes include a common infrared distance measuring probe, a Time of Flight (TOF) distance measuring probe and an optical triangular distance measuring probe which determine the distance by the intensity of reflected light.
The common infrared distance measuring probe determines the distance according to the energy of received reflected light, so that the common infrared distance measuring probe is closely related to the reflectivity of a reflecting object, and in actual use, the sensing distances of the reflecting objects with different colors and roughness are greatly different.
The TOF ranging probe adopts infrared light, and after the light is reflected from an object to the sensor, the distance between the sensor and the measured object can be calculated according to the time difference between the emission and the reception of the light; so if the TOF ranging probe's probe case surface is particularly bright and very close to the sensor, it will scatter too much light into the sensor and create artifacts and unwanted reflections; if the sensor is far away from the surface of the probe shell or the surface of the probe shell is rough, light rays can be reflected for multiple times, and unnecessary reflections cause great uncertainty in measurement; by integrating the above principle, the TOF ranging probe can solve the influence of the reflectivity of a reflector on the distance, but has high requirements on the installation of the probe shell and the TOF ranging module, the production process of the probe shell and the use environment of the probe shell (the probe shell cannot scrape flowers, friction and water drops), otherwise, the distance is tested incorrectly, and the problem of products is caused.
The optical triangulation probe determines the distance from the position of the reflected light on the receiver and from the trigonometric similarity and trigonometric function. The lens surface of the triangulation ranging module is close to the surface of the probe shell, and the reflected light of the probe shell can be controlled not to irradiate on the lens surface of the triangulation ranging module during design. Therefore, the optical triangular distance measuring probe can solve the problems of production of a probe shell of the TOF distance measuring probe, assembly of products and use of the probe shell, and also solves the influence of reflectivity of reflectors on the distance, but the power consumption of the optical triangular distance measuring probe is large and cannot reach the national standard.
