摘要
交流电源功率控制器(APCU)是实现飞机电气负载控制与电源自动化管理的重要组成部分。系统采用CAN总线设计实现了APCU与供电系统处理机和机电综合管理系统的通信。利用流和管道技术编写了基于DSP/BIOS的CAN总线的设备驱动程序。为了满足通信需求,本论文中共设计了2个CAN接口,一个为F2812内置的CAN接口模块,另一个为通过SJA1000的扩展CAN接口模块以备用。通过实际的通信试验,结果表明系统通信运行可靠,数据传输准确,符合预期的设计目标。
AC Power Control Unit(APCU) is an important component in fulfilling the automation of aircraft electrical load control and management of power automation.CAN bus is designed for communicating between APCU and electrical management system.CAN bus device drive is programmed with flow and pipe technology based on DSP/BIOS.Two CAN modules are designed to meet the requirement,one for F2812 inner CAN interface module and the other for expanded CAN interface module based on SJA1000 for standby.After communication test,the result proves reliably run,exactly transmission and objectives in line with expectations.
