Abstract | Sensor nodes combined with MEMS sensors can form a complete replacement for the existing cumbersome predictive maintenance systems. We have designed a system that can be used to monitor the bearing conditions of induction motors. The system called as WiBeaM (wireless bearing monitoring system) forms a network of sensor nodes that sense the vibration on motors and transmit the same to a central base station, this data is further analyzed through signal processing for defect diagnosis. We have used cheap off the shelf components to realise a real world application at a very low cost. Considering the low cost and the ease of deployment, our application is one of its kind in the domain. The solution has been implemented on Moteiv's Tmote-Sky nodes using ADXL105 accelerometer from Analog devices.The solution includes an application layer, transport layer for reliable data transfer and a MAC protocol for low power consumption. The challenges in the implementation span from the hardware to software. The aim was to select a cheap yet efficient sensor that could be compatible with the sensor node and build a software that can automat the otherwise cumbersome process of bearing monitoring. Whilst developing the application we have found that by proper selection of transmit power of the radio, single hop wireless transmission is more power efficient than the multihop. In sum, we have proved the viability of machinery vibration monitoring with wireless network technology by conducting testbed trials. |

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.
