摘要
电源功率控制器(PCU)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;它通过电气数据总线向供电系统处理机(PSP)传送配电中心的数据信息,并且接收PSP发送的信息命令并执行;本系统采用ARINC 429总线设计实现了PCU与供电系统处理机和机电综合管理系统的通信;编写了基于DSP/BIOS的ARINC 429总线的设备驱动程序;实际的试验测试结果表明,该通信电路运行稳定可靠,数据传输准确,达到设计指标要求。
Power Control Unit (PCU) is an important component in fulfilling the automation of aviation electrical load control and man- agement, with responsibility for transmiting the data of power distribution center to Power System Processor (PSP) through electrical data bus. The system adopts the ARINC 429 data bus to fulfill the communication between PCU and PSP, and the device driver of ARINC 429 is designed based on DSP/BIOS. The experimental results indicate that PCU is excellent in data transmiting with extendable performance.
