摘要
针对现代电网供电智能化的需求,采用ARM技术的STM32芯片,设计GUI交互型智能综合保护器。基本功能设计采用库开发方式进行,交互采用显示触摸技术、图形用户界面(GUI)、STem Win库开发方式完成,应用微实时操作系统μC/OS-III,进行保护系统多功能任务规划及任务运行管理设计,实现系统实时可靠运行,通过μC/Probe检测程序配置,对CPU使用率,系统任务、应用任务设计的合理性,系统整体运行状况进行检测,验证智能综合保护软件系统的可靠性与实时性。
Aiming at the demand of intelligent power supply in modern power grid,the ARM STM32 chip is used to design graphical user interface( GUI) interactive intelligent integrated protector. The basic function design is carried out using the Library Development mode. The interactive is completed by display touch technology,the GUI graphical interface and the STem Win Library Development mode. The micro real-time operating system μC/OS-III is used to carry out the multi-function task planning and task operation management design of the protection system,to realize the real-time and reliable operation of the system. Through the μC/Probe detection program configuring,detecting the CPU usage rate,the rationality of the system task and the design of the application task,the overall running condition of the system,the reliability and real time of the intelligent comprehensive protection software system are verified.
