Development of a WSN Framework for Mining & Civil Safety Monitoring Purposes

In this paper we describe the development of an IEEE 802.15.4 compatible wireless sensor network (WSN) node for mining & civil safety protocols. The sensor node will acquire and internally store data of sensors periodically. Starting times as well as the time intervals for the measurements can be freely programmed over the network system. As soon as an obstacles is detected in its proximity the node will automatically transfer data. Optionally sensor data can be delivered on demand. When in its idle state the node remains in power-down mode in order to minimize power consumption. Secondly attempt can also be make in this work that to generate the alerts as per settable range of unhealthy conditions. In normal Industrial data transfer environments standard current loops of 4mA-20mA or standard voltage loops of isolated 12V, 24V & 36v are used. But all these methodologies are associated with the long distance & short distance wired topologies. As wired communications are costly & needs the frequent maintenance cost appointments their forms the need of development of suitable profile with suitable data rates. The profile here developed form the unique wireless link using Wireless for such inter analog & digital data transmissions.
