摘要
为满足电磁选针器的性能测试及其在长时间运行过程中的稳定性检测与故障数据保存的要求,利用可重新配置的嵌入式测控系统和配套的软件,设计了一种采用激光位移传感器实现选针摆动位移的检测系统。通过对电磁选针器选针刀的位移与选针驱动信号进行实时采集和处理,实现了选针刀摆动规律的测量和选针响应时间的计算。该检测系统还具有异常选针时间分析和记录功能,用于选针器的稳定性检测。本文系统为选针器的优化设计和性能标定提供了一种精确的测量分析方法,并为后续的电磁选针器故障分析提供了数据支持。
In order to meet the requirements for electromagnetic needle selector performance testing and stability testing and fault data storage of electromagnetic selector in the long run,using the reconfigurable embedded measurement and control system and the associated software,a detection system using laser displacement sensor capable of realizing needle swinging displacement was designed. Through the collection and process of needle displacement and needle drive signal,a measurement of needle swing rule and calculation of needle selection response time were achieved. The actual test system can also analyze and recode abnormal selection time of needle selectors,and the stability testing for needle selectors is realized. The system provides an accurate measurement and analysis method for the optimal design and performance calibration of the selector,and provides the data support for the follow-up electromagnetic needle selector fault analysis.
