  • 脉冲激光测距中高精度时间间隔系统设计_田海军
    脉冲激光测距系统工作原理即单片机控制激光发 射装置发射占空比一定的激光脉冲,其中一小部分能量 到达接收电路,然后光电探测器将微弱的光脉冲信号变 成电脉冲信号并看作Start信号触发时差测量。激光的 大部分能量在空间中传播,遇到目标物后反射传播到 达接收电路,看作Stop信号结束测量,至此完成时差测 量[2]。TDC?GP22芯片记录Start脉冲到Stop脉冲之间的 时差,用于计算目标物到发射端的距离。(The principle of the pulse laser range finding system is that the single-chip microcomputer controlled laser emission device launches a certain laser pulse, in which a small portion of the energy reaches the receiving circuit, and the photodetector turns the weak light pulse signal into the electric pulse signal and is considered as the time difference measurement of the trigger time of the Start signal. Most of the energy of the laser propagates in the space. After the target, the reflection transmission reaches the receiving circuit, which is regarded as the end of the Stop signal and then completes the time difference measurement [2]. The TDC GP22 chip records the time difference between Start pulse and Stop pulse, which is used to calculate the distance between the target and the transmitter.)

  • OS实验报告以及源码
    父进程使用系统调用pipe( )建立一个管道,然后使用系统调用fork()创建两个子进程,子进程1和子进程2,父进程用系统调用signal()捕捉来自键盘的中断信号。当捕捉到中断信号后,父进程用系统调用Kill()向两个子进程发出信号,子进程捕捉到信号后分别输出下列信息后终止:      Child Process l is Killed by Parent!      Child Process 2 is Killed by Parent! 父进程等待两个子进程终止后,释放管道并输出如下的信息后终止    Parent Process is Killed!
