摘　　要：本文采用常用的MAX232等芯片设计了多速率429总线数据发送模块。在此基础上,以AVR单片机ATmega128为核心,研制了一种手持式多速率429总线测试仪。该测试仪具有功耗低,体积小,重量轻,携带方便,操作方便等特点,并可以实现429总线数据和串口(RS232)数据相互转换。A multi-bit rates module for sending data through 429 Databus was designed by using the common MAX232 and other chips. Based on that, a handhold 429 Databus Analyzer was designed with AVR MCU ATmega128. The features of the Analyzer are low power, small cubage, light weight, easy carried, easy operation, etc. It can also exchange data from 429 Databus to RS232 Port.
