Centralized infrared household appliance control device
Abstract：With the development of science and technology, intelligent home has also become a new field of electronic information technology applications. This design designs a centralized home appliance control system which uses infrared ray for remote control. This design uses the single-chip microcomputer as the intelligent control core of the remote control and reception. At the same time, it uses infrared emission tube and infrared receiver tube as a transmission device and uses infrared ray as a carrier of information. We can use them and an amplifying circuit to make up a integral infrared remote control system. This system can completes modulation and interpretation of signal by the coding and decoding of the single-chip program. If the screening of the target has been completed, the system can control the designated relay which is used to connect with electrical load and control the opening or closing of them. This design not only makes the control of household electric appliances intelligent, centralized , and simplified, but also conforms to the trend of the
intelligent life. At the last time，it has been proved that this design is practical and impactful,
