Wireless Sensor Network Design Of Coal Mine

A wireless sensor network (WSN) is a wireless network consisting of spatially distributed autonomous devices which use sensors to cooperatively monitor physical or environmental conditions, such as temperature, sound, vibration, pressure, motion or pollutants, at different locations. The development of wireless sensor networks was originally motivated by military applications such as battlefield surveillance. As the network install at mine pit. Wireless sensor nodes deposited at mine pit provide light, temperature, and activity measurements.There are many varied applications for WSNs at mine pit. They are used in industrial applications to monitor data that would be difficult or expensive to monitor using wired sensors. They could be deployed in wilderness areas, where they would remain for many years without the need to recharge their power supplies. They could form a perimeter about a property and monitor the progression of intruders. There are many uses for WSNs.The system's architecture of WSNs is designed. It is base application demand at mine pit. And design the node's hardware that base ARM7 processor LPC2103 as the MCU board. Another board include wireless communication module and signal strength survey module. The software's architecture and functional module are designed.Wireless nodes attached to circuits or appliances sense the current or control the usage. Together they form a dynamic, multi-hop, routing network connecting each node to more powerful networks and processing resources. Wireless sensor networks at mine pit are application-specific, and therefore they have to involve both software and hardware. SRDR protocol is designed that relate to both the application and to the wireless network.
