Design And Implementation Of Dynamic Loading Of Ultra Wide Band Fuse Test Signal

This article has explored the dynamic loading module of Ultra-wideband Fuze Test System.The hardware and software of this module have been designed and realized based on ARM+CPLD.In this article,the Ultra-wideband Fuze test signal synchronized control module which is based on TM32F103VET6(ARM),and the precise delay module based on LCMXO2280(CPLD)have been designed and realized,including the Digital-to-Analog Converter circuit,the Analog-to-Digital Converter circuit,the communication interface circuit,the serial port through signal circuit,the power supply and the PCB debugging.Based on this hardware platform,the software algorithm consists of DAC,ADC,peak search algorithm,parallel to serial convertion,serial to parallel conversion and serial communication have been designed and transplanted.This article has designed modulated signal for the dynamic loading portion of Ultra-wideband Fuze Test System.Meanwhile this article has designed the parameter display interface for monitoring parameters in real time based on MFC.Finally,the signal dynamic loading system was tested in the laboratory condition.The result shows that the maximum error of time is ±0.041 ns,and the mean square error is 0.022 ns.
