用于汽车防撞系统的激光脉冲编码产生装置
摘要：
本实用新型公开了一种用于汽车防撞系统的激光脉冲编码产生装置，其包括控制器U1、驱动电路、激光脉冲发生电路和按键编码单元；所述控制器U1与所述按键编码单元和驱动电路信号连接；所述驱动电路与所述激光脉冲发生电路信号连接。本实用新型的用于汽车防撞系统的激光脉冲编码产生装置，在将整个电路连接完成后，接通+200V高压电源、VCC电源(+12V)和+3.3V电源；控制器U1通电；此时由单片机产生脉冲编码信号，经过驱动器来控制激光的输出；可见本实用新型的用于汽车防撞系统的激光脉冲编码产生装置采用单片机对激光发射进行控制，其反应速度快；而且本实用新型所采用的元件较少，因此，稳定性较高。
摘要（英）：

The utility model discloses a laser pulse code production device for car collision avoidance system, it includes controller U1, drive circuit, laser pulse generating circuit and keyboard -coding unit, controller U1 with keyboard -coding unit and drive circuit signal connection, drive circuit with laser pulse generating circuit signal connection. The utility model discloses a laser pulse code production device for car collision avoidance system, after accomplishing whole circuit connection, switch -on + 200V high voltage power supply, VCC power (12V) and + the 3.3V power, the circular telegram of controller U1, produce pulse code signal by the singlechip this moment, controls the output of laser through the driver, it is thus clear that the utility model discloses a laser pulse code production device for car collision avoidance system adopts the singlechip to control laser emission, and its reaction rate is fast, and the utility model discloses the component that adopts is less, and consequently, stability is higher.
