摘　　要： 根据ARM芯片和μC/OS-Ⅱ实时操作系统的特点,设计了以ARM Cortex-M3为内核的嵌入式安全气囊电子控制模块。按照安全气囊的控制要求,分为不同的任务模块,各模块由嵌入式实时操作系统μC/OS-Ⅱ统一调度。试验表明,该系统在提高了系统的爆破精度、可靠性及数据可读性的同时,降低了系统的功耗和设计周期,从而节省了系统开发和维护的成本。 According to the character of Real -Time Operating System （RTOS） μC/OS-Ⅱ, the article introduces the system of airbag which takes the ARM Cortex - M3 as the main chip. Based on the requirement of the system , it is divided into several different module and all of them are uniformly managed by embedded RTOS μC/OS-Ⅱ system. The research indicates that this system not only improve the real -time ability and reliability and is readable, but also reduce system＇ s design cycle, as well as cut the cost of the development and maintenance of the system.

关 键 词： 嵌入式系统 实时操作系统 安全气囊
