激光检测在场地桩考系统中的应用

Application of laser detector in driving license examination

介绍了一种用激光检测机动车越界的方法。系统以MCUAT89S52为电控部分核心,选用可见红光波长的激光束,探测机动车在场地考试中是否越界。单片机与PC机通过串行接口进行双向通讯。系统采取激光束调制及其它措施保证了检测系统的可靠性,也可适用于不同车型的场地桩考。

A laser detection device is made for driving license exams. AT89S52 works as a kernel of the electric controller in this system. Two visible laser beams of red wavelength act as borders in this system. The device surveys whether the vehicle oversteps the boundary. The single chip of the system communicates with PC in mode of two-way serial communication. The method modulating laser beams is one of anti-jamming measures used in designing this system that raise both the ability of signal and the reliable operation of system. The system is adapted to varied automobile.
