| Abstract | This manuscript presents a two-stage distributed architecture for DAQ of thousands-channel large-area wire sensor network for physical experiment. The architecture can be divided into two units, the upper unit is for the data collection and storage, also including main control, quality monitoring, and data recording, the lower unit is for data sampling and transmission. The most prominent characters of this architecture are real-time capability, high precision synchronous data sampling, and easy scalable. We have built a prototype architecture for 16 cables (one cable containing 1920 channels) with the associated hardware modules, and tested the sampling synchronization, data transmitting and storage ability by using the cable simulator developed by ourselves. Test result shows that the sampling synchronization error between two channels with 100m apart can achieve 1ns. The tested maximum data rate from a cable (1920 channels) is 11.52MB/s, thus the total data rate is 1.47456Gbps for 16 cables (30720 channels). |

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.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
