Title: The design of test system of overload in high-speed penetration
Abstract
In the study projectile penetrating questions art methods, the onboard memory testing technology is now the most advanced kind. The design can be completed at high speed penetration environmental sampling, signal conditioning, signal storage memory test system is the key to this technology.
This article will use a high-speed storage environment Penetration test system design will be described. The system uses a piezoelectric sensor ICP interface, improve system response speed and noise immunity. It adopted a strong anti-jamming capability of the constant current source circuit design, to ensure that in the harsh environment of the test the whole system can be stable power supply. Using the STM32 chip ARM7 series chip as the central control of the entire system, complete power management, signal conversion and acquisition and operating input memory circuit. Finally, the impact of ground experiments verify the correctness of the entire system.
