摘　　要：针对野外环境进行的冲击波测试读数和擦除操作繁琐的情况,为了提高冲击波超压测试的效率,提出自带电源、带有擦除功能的U盘读数盒的设计。该读数盒通过USB控制芯片CY7C68013的GPIF接口与测试装置通信并向测试装置发送时钟信号和控制信号,将Flash中的数据暂时读入到其内部FIFO中。然后通过68013内部增强型8051单片机控制U盘文件管理芯片CH376S将数据存入到U盘中,实现对测试装置的U盘读数。通过现场实验证实,该读数盒可以简化野外冲击波测试繁琐的操作,提高冲击波测试的效率。Aim to the field of shock wave measurement readings and erase operation is cumbersome,in order to improve the efficiency of the shock wave overpressure test,proposed a kind of U disk reading box with power and the erasure function. The reading box communication with the testing device through the GPIF of the USB control chip CY7C68013, transmits clock signal and controls signal through this interface to read the data in Flash internal FIFO temporarily. Then the enhanced 8051 MCU in 68013 control U disk file management chip CH376S stored the data into the U disk. the realization of U disk complete U disk data reading. Through the field experiment found that the reading box can simplify the read and erase operation of the in field shock wave testing,improve the efficiency of shock wave testing.
