Perimeter defense system based on wireless sensor network

Abstract

The invention discloses a perimeter defense system based on a wireless sensor network. The perimeter defense system comprises a wireless monitoring node, a sensor network central control node, a monitoring central server and a portable monitoring terminal. Information collected by the wireless monitoring node through an external expanded sensor and the collected information is sent to the sensor network central control node by the wireless monitoring node in a wireless mode; the sensor network central control node is used for building wireless communication networks, receiving the information sent by the wireless monitoring node and processing the information by utilizing a data diffusion method, and transmitting the processed monitoring data to the monitoring central server in a wired mode; the monitoring central server is used for storing and analyzing the monitoring data and displaying monitoring information, when a defended object is invaded, the monitoring central server alarms and sends the monitoring information and alarm information to the portable monitoring terminal in the wireless mode; and the portable monitoring terminal visits data in the monitoring central server in the wireless mode. The perimeter defense system based on the wireless sensor network has the advantages of being low in cost, low in power consumption, flexible in arrangement, wide in monitoring surface and good in applicability.

Description

technical field [0001] The invention relates to a perimeter protection system based on a wireless sensor network, in particular to a "plug and play" perimeter protection system based on a wireless sensor network and using multiple sensing means. Background technique [0002] With the advancement and development of technology, the scope of battlefields in modern warfare is constantly expanding, providing full-dimensional and uninterrupted security monitoring for command posts, camps and other important military locations, discovering illegal intrusion targets in real time, and protecting personnel, facilities, and resources Protecting equipment and equipment from enemy agents or terrorist attacks has become an important challenge in modern warfare. In the civilian field, the security situation of important facilities such as airports, ports, and dangerous goods warehouses is not optimistic. However, physical perimeter protection measures (such as fences, walls, etc.) have be...

AI Technical Summary

Problems solved by technology

For example, fixed-point monitoring is usually used for video monitoring, and the monitoring range is small. Generally, continuous scanning is required, resulting in waste of resources, and real-time monitoring needs to be guarded by someone on duty; due to the characteristics of infrared technology, infrared monitoring systems have monitoring blind spots. It is easy to crack, susceptible to interference from environmental light sources and small animals, etc.; microwave fields and electronic fences are relatively susceptible to electromagnetic interference and paralyze the system, and the system is complex and the implementation cost is high

In addition, some security systems implemented by optical fiber, network and other wired wiring methods have complicated structures and processes, troublesome construction and long construction period.
