摘要:
为了提高炸药的性能，设计一种新型高精度多段爆速仪，以光纤作为传感器采集爆炸信号，通过峰值电压采样保持电路,保证了光纤获取爆炸信号波形峰值间的计时，并由FPGA进行数据处理，提高了系统的测试精度和稳定性，简化了电路设计和调试。文中对峰值电压采样保持电路、光电转换部分电路进行了详细的设计，并结合实验和误差对比分析系统的精度，结果表明本系统在精度上有很大的提高。
Abstract:
In order to improve the performance of dynamite, a new high-precision multiple detonation velocity meter was designed. Fiber optical was used as the detonator signals received by the transducer. By peak voltage sample-holding circuit, the time between wave peaks of detonator signals obtained from fiber optical was identified, and the data were processed by FPGA. By this means, the test accuracy and stability of the system were improved, and the circuit design and debugging were simplified. In this paper, peak voltage samplehold circuit and photoelectric conversion circuit were designed in detail. The precision of the system was comparatively analyzed combining with experiments and error. The results show that the system ensures a great improvement in accuracy.
