Mobile intelligent safety defense monitoring system based on wireless sensor network

Abstract

The invention discloses a mobile intelligent safety guard monitoring system which consists of a central monitoring server, base station nodes, a plurality of route nodes, a target node and image acquiring nodes. The central monitoring server includes a public known computer, a digital monitoring map and a monitoring serving processing module; in which, the digital monitoring map and the monitoring serving processing module are stored in the memory of the public known computer; the digital monitoring map is constructed in network mode comprising route nodes, base station nodes and image acquiring nodes, for transforming the really arranged areas needing safety guard monitoring into digital plane map displayed on computer; the central monitoring server and the base station nodes are connected by cable, the image acquiring nodes and the base station nodes are connected in wireless mode, and the base station nodes and the route nodes are connected in wireless mode. When a monitored object moves, the monitoring system of the invention locates and tracks the object in real time according to its position after moved and the intensity of the signal sensed by the sensor in network.

Description

technical field [0001] The invention relates to the field of security monitoring, more particularly, a mobile intelligent security monitoring system based on a wireless sensor network. The system realizes the mobile positioning of the target node through the broadcast signal strength between the target node and the routing node. Background technique [0002] Wireless Sensor Networks (WSNs for short) are composed of a large number of micro-sensor nodes deployed in the monitoring area, and form a multi-hop self-organizing network system through wireless communication. The network monitors the information of various environments or monitored objects in the area, and sends the information to the observer. Micro-small, energy-saving sensor node technology endows wireless sensor networks with broad application prospects. It has potential application value in many important fields such as military defense, biological monitoring, intelligent monitoring, emergency rescue, and traffi...

Problems solved by technology

[0003] Most of the existing security monitoring systems mainly realize the functions of abnormal detection and image acquisition within the monitoring range. The functions are very simple and cannot realize positioning and tracking; the alarm transmission is carried out in a wired way, and the deployment is complicated; the monitoring equipment is a camera, a sensitive cable, etc. Such as fixed equipment, poor mobility
