枪弹测速试验是用来检验产品的主要依据。是科研、生产及验收所必不可少的环节。在枪弹测速试验中,用单板机自动进行测量,数据处理并立即打印出所测速度值。从而大大简化了过去仪器测时,人工换算,人工记录的繁琐过程。提高了测量精度和可靠性,并使实验人员从大量重复的数据处理劳动中解脱出来,提高了工作效率。本文通过系统框图,程序流程图及部分接口电路介绍了单板机进行自动测量,数据处理及打印的设计思想和工作原理。
Bullet speed test is used to test the main basis for the product. Is an essential part of scientific research, production and acceptance. In the gun speed test, using the single-board automatic measurement, data processing and print out the measured speed value. Which greatly simplifies the past instrument measurement, manual conversion, manual recording of the tedious process. Improve measurement accuracy and reliability, and relieve experimenters from a great deal of repetitive data processing work, thereby improving work efficiency. This paper introduces the design ideas and working principle of automatic measurement, data processing and printing of single-board computer through system block diagram, program flow chart and part of the interface circuit.
