Abstract:

The communication network in coal mine underground is the foundation of colliery distributed monitoring system and plays an important role in transferring information when the production is in gear and events happens in coal mine underground, which is the key to keep the safety information expedite. A wireless sensor network (WSN) consists of an array of diverse micro-sensors, which is interconnected by a wireless communication network to provide plenty of sensing and monitoring services. It has the advantages of simple structure, flexible network, good efficiency and trustiness. Firstly, the paper brings forward a new project of the distributed monitoring system in coal mine underground based on WSN according to the analysis of special communication circumstance of coal mine underground. Then the safety theories of communication of WSN in coal mine underground are dissertated and the key techniques are discussed, on the basis of which a distributed monitoring system in coal mine underground based on WSN is designed. Finally, the layout and functions of WSN of coal mine underground in the whole distributed monitoring system are mainly researched, including the peacetime datum collection and emergent application when events happens.

I. Introduction

A wireless sensor network (WSN) consists of an array of sensors, of diverse types, interconnected by a wireless communication network. Sensor data is shared between these sensor nodes and used as input to a distributed estimation system whose function is to extract the relevant information from the available data. Fundamental design objectives of sensor networks include reliability, accuracy, effectiveness, flexibility. Each node has one or more sensing unit, an embedded processor, and low-power radios. The nodes act as information sources, sensing and collecting data samples. They perform routing functions, creating multi-hop wireless network fabric that conveys data samples to other sensor nodes. Nodes can also act as information sinks, receiving dynamic configuration information from other nodes or external entities. The rapid deployment, self organization and fault tolerance characteristics for WSN make them promising for a number of military and civilian applications.[1]
