摘要
激光测距系统是使用激光作为光源,依靠测量激光发射与接收时间来确定与目标距离的测距系统,它有测量速度快、精度高和使用方便等优点,在军事和民用等领域都有广泛的应用。本文使用EDA技术,以Quartus II为平台,使用硬件描述语言VHDL设计一款工业用激光测距系统。整个系统由按键控制模块、传感检测模块、核心控制模块和显示模块构成。按键控制模块主要完成与用户之间的交互功能,传感检测模块发射激光、接收回波信号然后产生对后续模块的控制指令,核心控制模块实现计数和距离计算的功能,显示模块将距离结果使用动态扫描的方式进行显示。本文经过原理设计、仿真调试和优化改进之后,成功设计出能够对五十米内目标精确测距的激光测距系统。

Abstract
Laser ranging system is a distance measuring system which uses laser as light source and depends on measuring laser emission and receiving time. It has many advantages, such as fast speed, high precision and easy to use. It is widely used in military and civil fields. In this paper, we use Quartus II as the platform and design an industrial laser ranging system using the hardware description language VHDL. The whole system is composed of key control module, sensor detection module, core control module and display module. The key control module mainly completes the interactive function with the user. The sensing detection module launches the laser, receives the echo signal and produces the control instruction to the follow-up module. The core control module realizes the function of counting and calculating the distance. The display module displays the distance result using the dynamic scanning mode. After the principle design, simulation debugging and optimization improvement, a laser ranging system capable of accurately locating the target within fifty meters is successfully designed.
