摘　　要：文章基于DSI总线协议,以PIC16F914为核心,设计了一种汽车安全气囊的控制系统。详细介绍了DSI协议的内容,着重设计了DSI硬件电路、微处理器外围电路及点火驱动电路,并编写了碰撞算法。通过实验,该控制系统能准确地判断碰撞的时刻,并及时引爆气囊,从而验证了设计的可行性。In this paper, base on the DSI bus agreement, a kind of automobile airbag control system with PIC16F914 as the core is designed. The content of the DSI agreement is introduced in detail, and the DSI hardware cir- cuit, microprocessor peripheral circuit and fii＇e drive circuit are emphasized. The collision algorithm is compiled. Through the experiment, this control system can accurately judge the collision time, and validate the airbag in time, which detonated the feasibility of this design.
