介绍了一种针对弹箭力学参数的综合测试系统的测试原理和设计方法。该系统的硬件电路以单片机为核心部件,实现了各类信号的测量、电机的控制以及PC机与单片机的通信等功能。通过运用LabWindows/CVI编程语言,实现了命令的下达、数据的接收、处理以及显示等功能。该系统克服了传统测试方法的不足,实现了自动化测试,方案可行合理。

A test principle and the design method for projectile's mechanical parameter measuring system were introduced. The core of the hardware circuit is the single chip. The hardware circuit realizes the functions such as signal measurement, motor control and communication between the PC and the single chip. The software of the host is programmed by Lab Windows/CVI, which realizes command transmission, data receipt, management and display. The system overcomes the shortage of traditional measurement method, realizes test automation. The project is reasonable and feasible.
