System for monitoring intrusion on basis of wireless sensor network

Abstract

The invention, which is applicable to civil security and surveillance and military intrusion detection, relates to a wireless network system for monitoring, identifying and judging the pathway of an intruding target by setting up a plurality of nodes. The intruding target can be located, identified and tracked by carrying out the extraction, analysis and data integration on the signal characteristic quantity of the sensors at each monitoring node, moreover, the function for a user to set sensitive areas is served, so that various alarm signals can be sent according to the closeness of the intruding target to the sensitive areas. Additionally, a monitoring sensor at the monitoring node is used for generating sleeping and waking-up signals on a real-time basis, thus achieving the deep sleeping and waking of the processor and the communication module and achieving the purpose of saving the energy of the monitoring nodes and guaranteeing that the target intruding the monitoring area can be reliably monitored at the same time. The invention has the characteristics of low cost, low power consumption, flexible arrangement and high applicability and overcomes the defects that the conventional video monitoring method for monitoring the intrusion has complex installation, poor concealment, vulnerable circuit and limited monitoring range and requires artificial event discrimination.

Description

technical field [0001] The invention relates to the application of a wireless sensor network in the field of target recognition and tracking, and is suitable for civilian security monitoring and military intrusion monitoring. Background technique [0002] Existing civilian security monitoring and military intrusion monitoring are mainly realized by video monitoring, and video monitoring can be divided into passive monitoring and active monitoring. Passive monitoring mainly refers to the camera device directly monitoring by collecting the visible light reflected by the object Objects, active monitoring mainly refers to the camera device using infrared light radiation "illumination", and then using ordinary low-light black and white cameras, color-to-black and white cameras or infrared low-light color cameras, to feel the infrared light reflected back from the surrounding scenery and environment to achieve night vision monitor. These two types of video monitoring systems are ...

AI Technical Summary

Problems solved by technology

Although it can reflect the monitored objects in a real-time, vivid and true manner, its cost is high and installation work is troublesome. It usually requires deployment in the decoration stage, and the maintenance work in the later period is large. Disadvantages such as manual identification of events

In civilian security monitoring and military intrusion monitoring, these shortcomings will directly affect the effectiveness of monitoring.
