本文介绍了SHPB的气动装置中由于机械式电触点压力表分度精度所限带来的较大误差,专门研制的以INTEL8031单片机为基本系统组成的专用微机测控装置的硬件组成、软件系统模块结构的主程序、测压子程序及测速子程序等。采用此测控装置,由于以控制SHPB的气压击发及测量打击速度,可减小置值时引起的误差和电触点闭合引起的较长信号延时,进而减少了打击速度的分散度。 This paper introduces the SHPB pneumatic device as a result of mechanical contact pressure gauge indexing accuracy of the greater error brought about by specially developed INTEL8031 microcontroller as the basic system consisting of a dedicated computer monitoring device hardware components, software system module Structure of the main program, manometry subroutine and speed subroutine. The use of this monitoring and control device, as to control the pressure of SHPB firing and measuring the attack speed, can reduce the error caused by the value set and the long contact delay caused by electrical contact closure, thereby reducing the speed of the blow of the dispersion.
