[Abstract]:At present, both central air-conditioning and household air-conditioning are controlled by infrared. The air conditioner is at the infrared receiving end, and the air conditioning remote control is at the infrared transmitter. Different from the infrared communication of common household appliances such as DVD and set-top box, infrared communication system of air conditioner needs to transmit more information content and data than other household appliances. This makes the frame format, communication protocol and coding and decoding algorithm of infrared coding and decoding of air conditioning more complex, and requires the communication system to have higher anti-interference ability. Air conditioning infrared codec system to transmit information content, including: temperature, wind speed, mode, switch and other special functions. TV and other appliances are generally transmitted a set of fixed key code values. Therefore, the infrared coding and decoding system with high efficiency has become the focus of industry research. Based on infrared coding and decoding technology, an infrared coding and decoding system based on air conditioning system is studied in this paper. The system integrates the functions of infrared coding and infrared decoding. In view of the complexity of infrared communication data in air conditioning, a calibration algorithm for infrared digital communication suitable for air conditioning is proposed, and a special data frame format is completed. Codec algorithm and communication protocol design to achieve the purpose of reliable data transmission. Through testing, the system has good anti-interference characteristics. The system fully considers and analyzes the characteristics of the digital signal produced by the infrared ray through the photoelectric converter. The coding and decoding method used in the system is simple, reliable, efficient and easy to operate. PIC24 single chip microcomputer is used as the main control of MCU, and the software system is programmed by C language. In the research work of this subject, through the application of PIC24 single chip microcomputer of MICROCHP, and the study and research work of the application technology of single chip microcomputer in C language, the infrared coding and decoding technology of air conditioning, The design work to be completed mainly includes: software system design, software flow chart design, core function definition, software code writing, infrared coding, infrared decoding, codec function simulation, debugging, Verification and program burning. Finally, the system needs to complete the testing work. Mainly include: software testing, circuit testing, codec testing several aspects. Through the relevant tests, the whole coding and decoding system is implemented.
