基于国产化平台的冲击波超压测试系统设计
Design of Shock Wave Overpressure Testing System Based on Domestic Platform
摘要
Abstract
Under the current trend of domestic substitution of special testing systems,a shock wave over-pressure testing system with domestic CPLD(Complex Programmable Logic Device)and ARM as the core architecture is proposed to address the technical issues of low safety,strong import dependence,and poor autonomous controllability of traditional shock wave overpressure testing systems.Among them,the ARM unit is responsible for responding to the system's work cycle instructions,while the CPLD controls the A/D conversion module to achieve data collection with a sampling frequency of up to 1 MHz and precise judgment of internal and external triggering logic.The data conversion results are transmitted through EXMC(External Memory Controller)and stored in eMMC memory,and finally transmitted to the upper computer for display through Ethernet.Field experiments have shown that this type of testing system has good reliability and can achieve high-fidelity acquisition and recording storage of shock wave overpressure signals in complex testing environments.It provides a practical and feasible solution for dynamic data acquisition and promotes the process of domestic replacement of key testing equipment.关键词
