以往的电子时间引信实验室动态性能试验,是靠人工监听引信作用时火工品的爆炸声音信号作为计时终点,这种方法误差大、实时性差、容易漏听信号等,影响试验结果的准确性。针对上述问题,提出了一种利用音频信号处理系统自动采集火工品爆炸声音信号的方法,经验证该方法可大大提高采集火工品爆炸声音信号的准确度,且响应速度快、系统性能稳定可靠,实现了对电子时间引信计时终点信号的有效采集,系统响应时间可满足电子时间引信计时精度考核的要求。
The past electronic time fuze laboratory dynamic performance test is based on manual monitoring of fuze explosives explosive sound signal as the end of time, this method error, real-time poor, easy to listen to signal leakage, etc., affect the accuracy of test results . In view of the above problems, this paper proposes a method of using audio signal processing system to automatically collect explosive sound signals of explosives. The method is verified that the method can greatly improve the accuracy of sound signals of explosion explosives collected, and the response speed is fast and the system performance is stable Reliable and realizes the effective acquisition of the signal timing end signal of the electronic time fuze, and the system response time can meet the requirements of the time precision evaluation of the electronic time fuze.
