介绍了一种应用于冲击波超压测试中的无线监控负延时存储测试系统,它由传感器、模拟适配调理电路、A/D变换器、存储器、控制电路、接口和电池组成,其存储装置由AVR单片机与CPLD共同控制两片NAND闪存,使用负延时功能实现高速完整存储.该系统具有可无线遥控、体积小、微功耗及抗高冲击等特点,适合于恶劣环境下数据记录和及时回传.%A negative delay storage test system was presented, which boasts of wireless monitoring and capability to test shock wave overpressure and consists of sensors,adaptive amplifier,A/D converter, memory, control circuit, interface and battery;the negative delay storage device,in which both AVR MCU and CPLD controls two NAND flash memories,can reliably work at a high speed. The experimental results show that this system can timely record and transmit the data in any harsh environment because of its features of wireless remote control,small size,low power consumption and high impact resistance.
