【摘要】 交通事故每年给人类带来巨大的损失。根据世界卫生组织发布的报告,全球交通事故的五大危险因素均直接或间接的与驾驶员缺乏交通安全意识有关。为从少儿开始培养交通安全意识,利用超声波测距模块、光电计数模块以及加速度感应模块设计出一种新型遥控玩具车,能在特定情况下自动停止,并发出报警,提醒儿童注意安全。通过分析遥控汽车结构特征以及玩具车转弯过程中的加速度分布,确定各模块的安装位置。这种遥控汽车有助于培养儿童良好的驾驶习惯,提高交通安全意识。更多还原

【Abstract】 Traffic accidents bring huge loss to mankind every year. According to the report released by World Health Organization,the five most dangerous factors in traffic accidents around the world are all related to drivers’ weak safety awareness. It is better to develop good driving habits in childhood. By analyzing the structure of traditional remote-controlled toy cars,a new type remote-controlled toy cars are designed with ultrasonic distance measurement module,photoelectric counting module and acceleration module. This cars can stop and give warnings to children under some circumstances. According to the remote-controlled cars’ structure and acceleration characteristic during swerving,the positions of the modules are determined. This toy cars are used to develop the children’s good driving habit and sense of safety. It benefits them through their life.更多还原
