摘　　要：本设计采用光电传感器作为计数装置,解决了传统仪器中激光发射器和接收器的调整问题,简化了仪器的操作步骤。同时选用51单片机作为控制核心,接收计数信号,处理按键信息,利用定时器计时,输出计数和计时结果到数码管进行显示。通过自制实验仪器,可提高教师业务能力,并减轻了实验仪器更新换代的压力。The design uses the photoelectric sensor as the counter,solving the adjustment problem with the laser transmitter and receiver of the traditional instrument and simplifying the operating steps. The design meanwhile uses the 51 single-chip microcontroller as the control core to receive the counting semaphores and handle the keystroke information. It also utilizes the timer to keep time,outputting the counting and timing results to be displayed on the nixie tubes. Through homemade experimental instruments,teachers can relieve the pressure of updating the experimental instruments in the lab as well as improve their professional proficiency.
