现有的循迹小车一般采用的是红外反射方式反馈小车的行驶轨迹，控制电路结构较为复杂，且成本较高，在小车行驶轨迹一定程度上容易出现偏差。采用LM393电压比较器设计的能在特定跑道上循迹行驶的轮式智能小车，该循迹小车主要包括太阳能供电部分和循迹控制部分。控制电路部分主要包括蓄电池、开关、第一和第二光敏感应电路、直流电机、比较电路和电机驱动电路。试验样机测试表明，以LM393电压比较器为核心控制的循迹小车具有控制精度高、起停快等特点，解决了循迹小车的控制电路结构复杂、行驶轨迹偏差较大的问题。

The existing tracing car,typically using the running trace of infrared reflectance feedback car,has more com?plex control circuit and high cost,and is easy to occur tracing error. The wheel type intelligent car with voltage comparer LM393 can do tracking running on a special runway. The solar tracing car is mainly composed of solar power supply part and tracing control section. The control circuit part of the tracing car includes battery,switch,first and second photo?sensing in?duced circuits,DC motor,comparer circuit,and motor driving circuit. Prototype testing result indicates that the tracking car taking voltage comparer LM393 as the core control has the characteristics of high precision,fast start,fast stop and so on. The tracing car can solve the problems of complex control circuits and course deviation.
