An ARM-based embedded identification system was developed.The system can identify the duty ratio of the pulse voltage on the secondary side of the voltage transformer.In this way,the polarity of the secondary side of the voltage transformer can be detected.The system includes two modules:data acquisition module and data identification module.Compared to the traditional DC/AC detection methods,it is able to detect the polarity more intelligently and conveniently.
