基于STC12C5A60S2单片机最小系统,开发了一款集循迹模块、蓝牙模块、电机驱动模块和避障传感器模块于一体的智能玩具车,实现循迹、避障、进退、转动和手机遥控等功能。大容量锂电池、充电模块和太阳能光伏板的组合组成电源,能够长时间为玩具车稳定供电。此外,玩具车具有双轴追光功能,利用PCF8591数据采集模块搭配光敏电阻和2个减速步进电机,实现智能双轴跟踪太阳。将太阳能玩具车放在采光良好的地方,其可高效利用太阳能光伏发电提供的电能,也能自动行驶在追踪太阳光入射角变化的轨迹上。

Based on STC12 C5 A60 S2 single chip microcomputer minimum system,an intelligent toy car is developed by integrating bluetooth module,tracking module,motor drive module and obstacle avoidance sensor module,which can realize tracking,obstacle avoidance,advance and withdraw,rotation and remote control by mobile phone and other functions. The combination of large-capacity lithium battery,charging module and solar photovoltaic panel forms the power supply circuit,providing stable power for the toy car for a long time. In addition,the toy car has a dual axis light tracking function by using PCF8591 data acquisition module with photosensitive resistance and two deceleration stepper motors to achieve intelligent dual axis tracking of the sun. By placing the solar toy car in a well-lighting area,it can automatically track the change of the sun′ s Angle of incidence,making efficient use of the electricity generated by solar photovoltaic power.
