摘　　要：介绍电动车跷跷板系统的设计与实现。该系统包括单片机系统电路、寻迹检测电路、平衡检测电路、步进电机驱动电路、数码显示电路等。在系统中,以AT89S52单片机为电动小车控制核心,使用反射式红外发射接收器来检测轨迹,步进电机作为动力源实现小车前进后退和转向控制,用2个水银开关控制完成平衡状态的检测,用数码管分阶段实时显示电动车行驶所用时间。3次实验数据表明,这里所提出的平衡检测方案是有效可行的。Design and implementation of seesaw system based on electric vehicle are introduced. The control system consists of AT89S52 single chip computer system,autonomous tracing circuit,balance detection circuit, driving circuit of stepping motor and LED display circuit. Centering on AT89S52 ,the track detection is realized by reflective infrared emitter and receiver and the steering of the vehicle is driven by stepping motor. The detection of balance state is implemented by two mercury switches and the travel time is displayed with LED separately. The scheme is proved to be effective and practical by experimental results during three tests.
