摘　　要：文中提出一种基于ARM7的多功能CT/PT(current transformer/Potential transformer)互感器测试仪的研制方法。系统采用双核设计,主处理器采用ARM7系列的LPC2214,从处理器采用24系列DSP C2407。为达到双核系统的高速数据交换的要求,采用双口RAM实现连接。旋转鼠标取代键盘,操作简单;选用320*240点阵图形液晶显示器使操作更加直观。软件设计基于μC/OS-Ⅱ实时操作系统的多任务设计,以实现对系统高效实时性的要求。本测试仪人机界面设计基于MiniGU(IGraphical User Interface),利用MiniGUI的丰富的图形库和强大的绘图功能,以达到更好的人机交互效果。This paper mainly introduces the research and manufacturing of the transformer tester based on ARM7 multi-function CT / PT （Current transformer/Potential transformer）. System uses a dual-core design. In the hardware design, the main processor uses ARM7 series lpc2214 and subsidiary processor uses24-series DSP chips C2407. In order to achieve high-speed data exchange of Dual-core system, system uses Dual-port RAM. Using the rotary mouse replaces the keyboard to make operation simple; Choosing 320＊240 bitmap form of liquid crystal displays. To meet the high-performance and real-time requirement to system, software design uses multi-tasking design based on μC/OS-Ⅱ real-time operating system. The human-computer interface design of this tester is based on MiniGUI （Graphical User Interface） according to using the rich graphics library and powerful graphics functions of MiniGUI to achieve better results of human-computer interaction.
