Infrared detection sensor switch control system and infrared detection sensor switch control method for lamp

Abstract

The invention discloses an infrared detection sensor switch control system and an infrared detection sensor switch control method for a lamp. The system comprises an infrared emitter, an infrared proximity sensor, an interrupt module and a central processing unit (CPU), wherein the infrared emitter is used for emitting infrared rays with a certain wavelength range; the infrared proximity sensor is used for receiving the infrared rays which are reflected back; the interrupt module is used for sending an interrupt signal to the CPU when the infrared proximity sensor receives the reflected infrared rays with longer wavelengths; the CPU is used for adjusting the current of the infrared emitter so as to enable the infrared emitter to emit the infrared rays with the certain wavelength range outwards, indicating the infrared proximity sensor to filter the infrared rays, which have shorter wavelengths and are reflected back by a lamp shade, according to a preset infrared ray return reception reference wavelength, and executing the command of turning on or off the lamp according to the interrupt signal. The system and the method realize the distance and penetration capacity which are inaccessible to the traditional infrared rays; the system can be completely installed in a lamp body, and is compact in structure, small in space occupation and high in practicality and reliability.

Description

technical field [0001] The invention relates to the field of lighting technology, in particular to an inductive switch control system that utilizes infrared rays and ambient light to safely penetrate a lampshade and act in real time and an implementation method thereof. Background technique [0002] With the improvement of economic living standards, people's requirements for modern smart home life are also increasing, especially the home is safe and beautiful and practical. The existing infrared on the market uses a fixed wavelength to work. The existing infrared detection and sensing equipment will cause product The structure itself is complex, it takes up a lot of space, the sensing distance is short, and it cannot penetrate general non-transparent lampshades, such as PC diffusion and milky white lampshades, and the product itself is not reliable. Contents of the invention [0003] The object of the present invention is to provide an infrared detection sensor switch cont...
