Research On Multi-sensor Geological Disaster Monitoring System

Massive property damages are caused by all kinds of geological disaster each year, effective monitor of geological disasters is one of important measures to reduce economic losses and casualties. The application of wireless sensor network to disaster monitoring makes it easy to realize real-time monitoring and data collection. But many problems are still found in the process of the current application of monitoring system.This article analysis many objective deficiencies of the current routing protocols and puts forward a new routing protocol referring to the latest EEUC protocol. The new protocol improves the candidate cluster head selection strategy and puts the current energy parameter and peripheral node density function of the nodes to choose survival probability function, further choose the best cluster head and reasonable clustering. Also it uses positive feedback of pheromone and way of collaboration with each other in ant colony algorithm for reference, joins the node current energy parameters into consideration to improve the probability function. The results of simulation experiments show that the new IE_ANT protocol can achieve better system monitoring and better choice of the routing path between clusters.The data throughput and power consumption in geological disaster monitoring system is very big, how to reduce the communication overhead through data compression has become a very urgent demand. This article introduces compressed sensing theory principle, analyzes some problems of the common algorithm. Also, based on the basic idea and principle of the subspace pursuit algorithm, this article successfully improves the computing efficiency and reconstruction precision of the algorithm. The results of the data signal and image reconstruction get through experiment verification, them verify the reliability of the improved algorithm, make better data transmission on the basis of the data compression.
