摘要
介绍了一种新型的电力故障录波器的软硬件设计,该装置的主处理器选用了TI公司的浮点处理器TMS320C33芯片,对电力系统进行故障诊断及记录故障发生时系统的动态电参量,满足了故障录波数据测量的高精度要求。主控处理器选用了Motorola公司的ColdFire 5282,它是与上位机监控系统连接的桥梁,设计了丰富的通信接口,负责转发监控命令和故障记录等,ColdFire 5282上移植了μClinux嵌入式操作系统,引入先进的任务调度机制及文件设备管理,提高了系统的稳定性。
The paper describes the hardware and software design of a new type of electrical fault recorder. In order to satisfy the requirement of the high accuracy of the data, TMS320C33 is used to diagnose the electric power system and record the parameter of electric power system when an inaccuracy or an abnormity occurs. Adopt ColdFire 5282 as the main control processor, it is the bridge between PC supervision system and fault recorder. the processor which transfers watch orders and failure record has rich interfaces.ColdFire 5282 transplants the embedded operate system p, Clinux which introduces high performance of assignment management mechanism and file systems. This enhances the stability of the system.
