摘要
本系统以Philps公司生产的LPC 2292 ARM单片机为基础构成保护测控单元的主控制板,完成对一次设备的保护,测量和控制功能;以Philps公司生产的P89C668单片机为核心构成键盘、显示板,完成人机接口功能;可选择使用工业以太网接口和CAN总线接口。移植μCOSⅡ实时操作系统,构成标准的嵌入式系统。微机保护算法采用傅氏算法;软件设计包括微机保护主程序。
In this systerm, LPC 2292 ARM from Philps company is baseplate which constitute the protective and metdcal central control panel. It can protect, measure and control distributive equipment and so on. P89C668 SCM is core which is make up of keyboard, display and man-machine conversation. We can use industdal Ethemet or CAN bus to connect. Real-time operating system/COS which make normal embedded system. The microprocessor protective algodthm is Fourier algodthm. And the protected program includes the main program, the sample interrupt service program and the trouble-disposing program etc..
