新型通用智能单元系统的设计

基于新型微处理器芯片MSP430F149C和多任务实时操作系统构建了一个全新的通用智能化单元系统。该系统的硬件结构可满足当前电力系统多数智能终端单元、控制单元的需求。而实时操作系统大大改变了传统的软件开发过程，能克服顺序结构软件而导致的软件代码结构复杂、可移植性和可扩张性差的缺点。配备自主开发的多任务实时操作系统后，该系统具备了智能单元的软、硬件基础。用户基于此通用系统的软件开发、升级和维护变得较容易，且设备软件的性能得到保证。实际应用表明该系统的性能好。

Design of general intelligent unit system

A gener al intelligent unit system is proposed,which is based on MSP430F149C MCU w ith embedded RTOS(Real Time Operation System).Its hardware structure can sat isfy the require-ments of most intelligent terminal units and control units,w hile RTOS can overcome the disadvan-tages of sequentially structural software ,such as complicated code structure and poor transplantability and extensibilit y.Equipped with own-developed RTOS,the general system has had both hardware a nd software platforms ,with which the development ,update and maintenance of t he intelligent unit software become easier and the software performance of the unit is ensured.The application shows its good system performance.The projec t is supported by National High-Tech.Industry Development ([2000]188 3).
