基于RTOS的廉价10kV微机保护平台

a cheap 10 kV microcomputer-based protection platform based on the RTOS

嵌入式实时操作系统(Real-Time Operating System,RTOS)以其实时性、可靠性、易维护性和易扩展性等诸多优点,在工业控制领域中得到越来越广泛的应用。采用TI公司生产的TMS320F2809DSP处理器作为嵌入式数据处理主芯片,在其周围扩展了简单的外围器件,并移植了源码公开的uC/OS-II实时操作系统内核。在此软硬件基础上开发了功能完善、结构相对简单的低成本微机继电保护嵌入式系统平台,并利用此平台开发完成了一系列10 kV微机继电保护装置。实践证明该平台性能可靠,具有较强的实用性。

Because of the real-time,high reliability,easy maintenance and easy expansibility,t he real-time operating system（RTOS） is widely used in the area of industry control.DSP processor TMS320F2809 produced by TI is used as a flush bonding data processing chip,a nd around the chip some simple peripheral devices are extended,and the kernel of open code RTOS of uC/OS-Ⅱ is transplanted.Based on the software and the hardware,the flush bonding platform of the microcomputer-based protector is developed.The platform has perfect function,low cost and relatively simple structure.Using the platform,a series of 10 kV microcomputer-based relay protectors is designed.The platform is proved dependable and practical.
