| Abstract | In the process of mining, the sensor is very important for mining safety to monitor gas concentration. With increasing of electronic equipments in coal mine, the electromagnetic interference becomes serious now. There were false alarms of sensors under harsh EMI environment. Therefore the interference immunity of the sensor becomes very important. In order to clear up false alarms, caused by Electromagnetic Interference (EMI), a novel field way was brought forward in which the simulation and radiated emission measurement were adopted to accomplish the analysis of shielding property about methane sensor. The simulation software HFSS of Ansoft company was adopted. The data was acquired through the R&S spectrum analyzer FSP7. With analyzing the influence of cable aperture on enclosure shielding properties through simulation and measurement, the optimization of explosion-proof enclosure was finished according to the distribution of radiated interference characteristics and simulation of the trumpet structure shield performance. The running results demonstrated that the problem of false alarms had been resolved successfully with the optimization of explosion-proof enclosure. It is concluded that the improved shielding and filtering are highly significant in enhancing the Electromagnetic Compatibility (EMC) of the methane sensor. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.
