多路激光测速控制系统的设计

Design of Multi-Channel Laser Velocity Measurement Control System

针对当前测量弹速衰减规律时常采用多个激光区截装置分布式测试后再进行数据重构分析,而各装置时钟基准不一致引入测量误差的问题,设计了一种基于STM32的多路激光测量子弹飞行速度装置的控制系统。该系统多路激光计时模块采用同一时间作基准,获取多组基于一个时钟的测试数据进行子弹飞行过程速度衰减规律研究,系统采用以太网将数据传输至上位机进行数据处理,可对测试系统进行远程操控,测试结果表明,该控制系统可靠稳定、实现了统一时钟的多路激光测速装置的远程控制。

In view of the current measurement of the elastic velocity attenuation law,multiple laser segmentation devices are often used for distributed data analysis and data reconstruction analysis,and the clock reference of each device is inconsistent to introduce measurement error.The paper designed and implemented a control system based on STM32 multi-channel laser measurement bullet flight speed device.The multi-channel laser timing module of the system used the same clock as a reference to obtain multiple sets of test data based on one clock to study the speed decay law of the bullet flight process.The system used Ethernet to transmit data to the host computer for data processing,which can remotely control the test system.The field test results show that the control system is stable and reliable.The system realizes the remote control of the multi-channel laser speed measuring device with unified clock.
