基于VXI总线枪弹杀伤力测试系统应用程序开发
本文将基于VXI总线的虚拟仪器技术应用到弹丸测速上，特别是应用到枪弹杀伤力的检测中，开发出了一种基于VXI总线寄存器基的枪弹杀伤力测试系统应用程序。该应用程序根据我国刑事科学技术中对枪弹杀伤力的鉴定方案和标准，可定量的提供枪弹杀伤力的测试结果。
在软件设计上采用美国NI公司的LABWINDOW/CVI开发环境，设计出了具有人性化界面的应用程序，利用上位机强大的运算能力实现了针对不同弹种的数据处理及显示，最后依据应用程序所示动能值和比动能值，为枪支杀伤力的刑事科学鉴定提供依据。
基于该总线模块的应用程序可配接多种区截装置，适用于多枪种的测试。本文最后对所开发的枪弹杀伤力测试系统应用程序进行了实验研究，实验数据验证了本应用程序功能的正确性及工作的可行性。

Abstract
Bullet lethality of Criminal Identification of the rule of law is maturing more and more important. The contents of this article for the detection shootings and trafficking, manufacturing, modification, smuggling and gun-related cases can provide an indispensable means to provide the indispensable basis for the sentencing of forensic science.
This research is benefit VXI bus-based virtual instrument technology to the projectile speed measurement, in particular, to the bullets of mass destruction detection, the development of a register-based VXI bus-based bullet lethality test software.. According criminal science and technology identified the bullet lethal programs and standards, the software can be a quantitative test results of the bullet of mass destruction.
U.S. NI company LABWINDOW/CVI development environment for software design, application design with user-friendly interface, the use of powerful computing capabilities of the host computer for different projectile types of data processing and display, and finally the software show the value of kinetic energy and per-kinetic energy values provide the basis for the scientific appraisal of firearms, lethal criminal.
The bus module-based software applications can be connected with a variety of sensate device, multi-gun test. Finally, the test software developed by the bullets of the experimental study, experimental data to verify the correctness of the functionality of the software, the feasibility of the work.
Key words: VXI bus, LABWINDOWS/CVI, virtual instrument, user interface, callback function
