摘要
针对冲击波场测量中存在的通用测试系统采样速度较慢、布设不方便等问题,研制了具有增益可调和无线数据传输功能的新型高速冲击波压力测试系统,信号输入级使用电荷输出型压电传感器并设计了信号调理电路,存储模块使用铁电存储器实现高速存储省略了传统的缓存电路。经试验证明系统能够稳定运行,并能够适用多种电荷输出型传感器。
Because of the existing difficulties in the measurement of shock wave speed and inconvenient layout, a new high - speed shock pressure test system gain and wireless data transmission. Piezoelectric sensors are used to send charge field such as slower sampling is developed, with adjustable signals output and a signal regulation circuit is designed, ferroelectric memory is used in the storage to realize high - speed storage and the traditional buffer circuit can be omitted. Proved by the test, the system can operate stably and suit for a variety of charge output type sensors.
