火箭橇测速电子测时仪的设计与应用

Design and Application of Electronic Time Measurement Instrument in the Rocket Sled Velocity Measurement

对靶场测试中火箭橇断靶测速以及某些强电磁干扰环境下电子测时仪可靠性降低的情况进行了分析。针对特定强电磁干扰环境,对信号进行了隔离和整形设计,并使用CPLD进行时间测试。研制的抗强电磁干扰的电子测时仪得到了良好的应用效果。

In the rocket sled velocity measurement by cutting off wire,the reason of electronic measurement instrument reliability reduced in some strong electromagnetic interference is probed.Aimed at a particular strong electromagnetic interference environment,the signal is isolated and designed with the overall shape,and the time is tested by CPLD.The developed anti-electromagnetic interference Electronic Time Measurement Instrument has a good application effect.The design method and application is discussed in detail in this paper.
