The Application Of Vibration Signal Collection And Analysis In Base Station Protection

In recent years, people witness the rapid development in communication network, especially in wireless network. In order to cover the rural places outside of the city completely such as village, railway and both sides of the highway, the communication operation enterprises established large amount of base stations. However, due to the few inhabitants and guard-less situation in the base stations, burglaries of equipment and cables occur frequently, which lead to the severe economic losses to those operation enterprises. What’s worse, the network paralysis and interrupt of main lines and important lines resulting from destroy of network equipments may bring more severe consequences. Now the main precautionary measure is access control system linked remote alarm, which is very passive. Once the warning message is received, it indicates that the illegal invasions have occurred or the equipments have been broken.Based on actual demand, we have developed a vibration prevention system for protection of the base station buildings as a whole. As soon as there are illegal invasions which will inevitably tap the walls and doors, where vibration probes are widely deployed, the prevention system will keenly upload effective alarm and trigger the interlock equipment.Through the analysis of vibration phenomenon, this thesis has concluded a set of effective analytical method and made an analysis meter which can realize its function through the application of MCS51series singlechip and send the information to interlock equipment effectively.The practical test results show that the results of this vibration signal processing has basically up to the design demand, meanwhile; its technology has achieved domestic leading level.
