Abstract:

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 swinging displacement was designed. Through the collection and process of needle diplacement and needle drive signal, a measurement of needle swing ruleand 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.

Key words: electro-magnetic needle selector, selecting needle response time, law of needle selectingcutter movement, real-time detection
