WIRELESS SENSOR NETWORK ARCHITECTURE BASED ON MULTIFUNCTIONAL AND COMPOUND SENSORS

BEIJING INSTITUTE OF INFO...

1. A wireless sensor network architecture based on multifunctional and compound sensors for monitoring a moving target, characterized by comprising:a plurality of sensing modules executed by a processor, each of the sensing modules comprising a plurality of first sensor nodes and a second sensor node, the plurality of first sensor modes and the second sensor node forming a detection area; wherein the first sensor nodes are used for collecting a target signal of a moving target after sensing that the moving target enters the detection area, pre-processing the target signal, extracting feature information of the moving target, analyzing the feature information of the moving target to form primary target information, and transmitting the primary target information to the second sensor node, and the second sensor node is used for performing moving target matching and association on the primary target information of the moving target that is transmitted by the plurality of first sensor nodes, and correcting the associated primary target information to form secondary target information;
a relay transmission module executed by the processor connected with the sensing modules, used for communicating with the second sensor node for receiving the secondary target information; and
a computer connected with the relay transmission module, used for receiving the secondary target information transmitted by the second sensor node, synthesizing and calibrating the secondary target information, simultaneously acquiring situation evaluation of the moving target by merging the calibrated secondary target information, and forming advanced target information according to the situation evaluation of the moving target.
