Monograph title: Progress in Mine Safety Science and Engineering II - Proceedings of the 2nd International Symposium of Mine Safety Science and Engineering Issue date: 2014 Publication year: 2014 Pages: 359-362 Language: English ISBN-13: 9781138001220 Document type: Conference article (CA) Conference name: 2nd International Symposium of Mine Safety Science and Engineering Conference date: September 21, 2013 - September 23, 2013 Conference location: Beijing, China Conference code: 102809 Sponsor: China Academy of Safety Science and Technology; North China Institute of Science and Technology; China University of Mining and Technology; McGill University; National Safety Council Publisher: Taylor & Francis - Balkema, P.O. Box 447, Leiden, 2300 AK, Netherlands Abstract: The safety monitoring system is one of the most essential components for the safety protection system in the production process of the coal mine. The number of power electronic equipment such as inverter and other monitoring systems for has risen steadily. This paper introduces the principle of electromagnetic interference and the working principle of the inverter. We summed up the impact of the inverter to the monitoring system, carried out our solution method to the inverter harmonic interference phenomena which may cause side effects to the hardware. In the application field, this paper has also made a certain reference and guidance to the mine safety production. © 2014 Taylor & Francis Group.
