Problems solved by technology

These types of switches have their own disadvantages. For example, the voice-activated type is not suitable for noisy places, although the touch type can be automatically turned off but not automatically turned on, the photosensitive switch cannot automatically turn off the lights when there is no one.

Abstract

The invention discloses an indoor lighting control system comprising a single chip microcomputer, a time delay selection circuit, a relay, an ambient brightness sensing module and a pyroelectric infrared sensor, wherein the input end of the single chip microcomputer is connected with the time delay selection circuit, the ambient brightness sensing module and the pyroelectric infrared sensor and the output end thereof is connected with the relay. According to the indoor lighting control system, whether there is a man in a room and the brightness in the room are respectively detected by the pyroelectric infrared sensor and a photoelectric sensor, signals are analyzed, processed and controlled by the AT89C52 single chip microcomputer, and software programs are set, thus realizing intelligent control on lighting equipment and achieving the purpose of energy saving. The indoor lighting control system has the advantages of simple structure, sensitive reaction and low cost.

Description

technical field [0001] The invention relates to the technical field of control circuits, in particular to an indoor lighting control system. Background technique [0002] With the development of the economy and the advancement of science and technology, people have higher and higher requirements for lighting. The traditional manual lighting control system technology has been strongly impacted by the times, and the "smart lighting" technology has emerged and developed rapidly. . The general manual control system refers to the system composed of a single switch or a group of switches and dimming devices that are operated by individuals through the switching of buttons, selecting yellow diamonds, tilting or remote control, and other means. It has the advantages of small scale and low cost. , but as people pursue automation, intelligence, and energy saving, manual control systems are increasingly unable to meet people's needs. For example, when there is no need for lighting, w...
