Software Of Relay Point For Underground Intrusion Detection System

Cultural relics and historic sites,as the cultural inheritance of the Chinese nation for thousands of years,contain the historical footprints of the rise and fall for thousands of years.With the passage of time,the values of these cultural relics and historic sites have been gradually increased,and the theft of criminals has become increasingly rampant.The current situation of relics protection is very serious.Due to the characteristics of underground sites with wide distribution and complicated terrain distribution.This dissertation designs a scheme of underground intrusion detection system based on low-power wireless sensor network.Compared with the existing underground object protection system,the detection system has the advantages of simple system construction operation,strong real-time detection and long working life.According to the demand analysis of underground intrusion detection system,the dissertation completed the overall scheme design and network structure.The dissertation introduced the software part of the system relay and the alarm recognition algorithm.The system relay software part mainly includes four parts: software main frame design,data storage module design,server network protocol and detection network protocol.In the alarm recognition algorithm part,the overall flow of the alarm recognition algorithm is designed,and the four parts of signal preprocessing,endpoint detection,feature extraction and similarity calculation are verified in detail.The dissertation finally tested the communication quality and system debugging.The results showed that the detection system can achieve basic functions and work stable.The system station has the function of expanding the detection range,and can reduce the false alarm rate to some extent.
