In chapter three and four the RF module with USB interface, and the infrared emission and reception system are designed; chapter five is the debug and experiment of embedded infrared communication system.In this paper, the main jobs are:(1) Studied the short-range wireless radio frequency communication technology, designed the radio frequency module using high-speed SOC (system-on-chip) C8051F010 and RF transceiver chip CC1100 as the main control unit. Use the USB to serial chip designed the RF module communicate with the host computer.(2) Designed infrared countermeasure systems based on embedded technology and infrared communication technology use Atmega16L.(3) Programmed the software of the embedded infrared communication system, hardware drivers and signal process.(4) Give the experiment of system information transmission error rate and transmission distance.(5) Give united debug of the system and the solution encountered in debugging process. Innovation: use the PWM mode of AVR MCU create the precise 38KHz carrier but without the use of the CPU, collimator and focus system was added to the launch and receive part, get good results.
