Design And Implementation Of A Kind Of Multifunctional Small Size Pmoled Display System

At present, both the central air conditioning and home air conditioning is controlled by infrared ray. Air conditioner in the infrared receiver, air conditioning in the infrared remote control sender. With common household electrical appliances such as TV, DVD, set-top boxes of different infrared communication, infrared communication system required to transmit the information content and data volume is far greater than other home appliances. This makes the air conditioning on the infrared decoding frame format, communication protocol and the decoding algorithm is more complex, requires communication system have higher anti-interference ability.Information content transmitted via infrared decoding system, including for example:temperature, wind speed, mode, switch machine and other special features, etc. Home appliance such as TV is usually transmitted a fixed set of key values. Therefore, the efficiency of the air conditioning of decoding ability infrared decoding system has become the focus of industry research.This topic is based on the infrared decoding technology, according to the characteristics of air conditioning in a wide range of data and information research a kind of infrared decoding system based on the air conditioning system. The system is integrated infrared coding and decoding function, the complexity of the infrared communication data for air conditioning, innovation put forward a kind of applicable to air conditioning calibration algorithm of infrared digital communications, and complete the data frame format, decoding algorithm and the design of communication protocol, to achieve the purpose of reliable data transmission. After the test, the system has good anti-interference characteristics. Give full consideration to the system and analyzes the infrared after photoelectric converter, the characteristics of the production of digital signal system adopted by the decoding method is simple, reliable, efficient, easy to operate.Topic proposed PIC24 singlechip as the MCU control system, software system using C language programming.Research work on the subject, through the use of the PIC24 singlechip of MICROCHP, as well as to the single-chip computer application technology, C language, air conditioning infrared codec technology study and research work, to complete the design work mainly includes: software system design, the flowchart of software design, the functions of the core function definition, software code,infrared coding, infrared decoding, the decoding function simulation, debugging,verification and program burn, etc.Finally, all the test work needed to complete the system. Mainly includes: software testing, test circuit, decoding testing several aspects. Through tests, complete implementation the decoding system.
