摘　　要：随着飞行器电子综合化技术的发展,数据总线在飞行器中得到大量应用;为满足某飞行器总线系统测量的需求,文章设计了一种基于CAN总线的遥测数据处理模块;硬件部分主要由CAN总线驱动器模块、DSP数字信号处理模块、FPGA逻辑处理模块组成;软件设计包括TMS320F28335的初始化,CAN总线数据处理和外部中断处理三部分;该模块用于某飞行器双路CAN总线数据的采集及处理,并经过了多次飞行试验验证;该模块简化了系统设计,实现了高速、可靠的CAN总线遥测数据处理。With the development of the integrated technology of aircraft electronics, data bus has been widely used in aircrafts. In order to satisfy the requirement of data bus system＇ s measurements for a certain aircraft, we designed a kind of telemetry data processing module based on CAN bus. The part of hardware mainly consisted with bus driving module , digital signal processing module and logic processing module. The design of software included initialization of TMS320F28335, CAN bus data processing and external interrupts. The module is used for receiving and processing of a certain aircraft＇ s dual CAN bus data in many flights test. The module simplified the system design, and realized the high--speed, reliable CAN bus telemetry data processing.
