This design uses a wide range of uses infrared communication technology designed a computer-based logic analyzer infrared serial port, this project was supported by SM0038 infrared receiver head, STC89C52 microcontroller, MAX232 level converter, DB9 constitute the hardware part, by the next crew procedures and upper Machine procedures constitute software. Design logic analyzer can be a variety of electrical infrared remote control signal emitted by the identification, storage and reproduction. Hardware interface can be identified by infrared infrared signal and sent to MCU processing, then use the VB development of virtualization software on a computer screen real-time display of the infrared signal waveforms collected to facilitate the designer of various modulation infrared signals visual of analysis and research. Key words：Serial Infrared communication Infrared logic analyze. 目 录  TOC \o 1-3 \h \z \u  HYPERLINK \l _Toc250967555 摘 要  PAGEREF _Toc250967555 \h I  HYPERLINK \l _Toc250967556 Abstract  PAGEREF _Toc250967556 \h II  HYPERLINK \l _Toc250967557 引言  PAGEREF _Toc250967557 \h 1  HYPERLINK \l _Toc250967558 1 红外线介绍  PAGEREF _Toc250967558 \h 1  HYPERLINK \l _Toc250967559 2 串口通信原理  PAGEREF _Toc250967559 \h 1  HYPERLINK \l _Toc250967560 2.1 波特率选择  PAGEREF _To
