为了能通过对枪械射击时产生的火光进行观察来测量枪械射击的频率,运用模电和单片机相关知识,开发了一种基于光电效应基本原理的光电射击频率计,这种仪器具有精确可靠,稳定性好,成本低廉,可以给枪械射击频率的测量带来极大便利。 In order to be able to measure the firing frequency of the firearms by observing the firelight generated when the firearms were shot, a photoelectric shooting frequency meter based on the basic principle of photoelectric effect was developed by using the knowledge of die-power and single-chip microcomputer. The instrument has the advantages of accurate and stable Good sex, low cost, can bring great convenience to the measurement of firearms firing frequency.
