摘　　要：随着智能电能表功能越来越复杂、灵活性要求越来越高,其暴露出来的软件缺陷问题也越来越多。针对这些问题,研究设计了一种基于嵌入式RTOS的电能表软件实现方案,该方案将电能表软件划分为内核模块、计量模块、主应用模块、扩展应用模块等几个独立的模块,并充分利用嵌入式RTOS在多任务处理及进程间通信等方面的优势,将电能表软件系统进行合理、有序的分层以及模块化划分。通过这种设计方式,既保证了电能表核心功能的稳定、可靠性,同时也兼顾了软件功能易于扩展的灵活性。Along with the situation that the functions of smart meter become more and more complicated and flexible, and there exposes more and more software defects. Due to these questions, a design scheme of smart meter software based on embedded RTOS is proposed. Through this design, the whole meter software is divided into kernel module, metering module, main application module and extensional application module. It makes fully use the properties of embedded RTOS on multitasking and inter-task communications, and the whole software system is divided reasonably and orderly into several parts based on module and hierarchy design method. With this design method, it not only guarantees the stability and reliability of kernel functions of electric meter, but also satisfies the flexibility of expanding new software functions.
