The invention relates to a wireless-sensor-network three-dimensional positioning system. The system is characterized in that the system comprises a node to be positioned, four positioning detection nodes and one positioning fusion processing node; the node to be positioned is connected to the positioning detection nodes and the positioning fusion processing node respectively; the positioning fusion processing node is connected to each positioning detection node; the node to be positioned comprises a central processing unit, a first timer, a first Zigbee module, a signal generating unit, a signal modulation unit and a signal emission unit; each positioning detection node comprises a microprocessor, a second timer, a second Zigbee module, a first GPS positioning unit, a signal receiving unit, a noise filtering processing unit, a signal amplification unit and a signal demodulation unit; the positioning fusion processing node comprises a fusion processing unit, a second GPS positioning unit and a third Zigbee module. In the wireless-sensor-network three-dimensional positioning system, through establishing a binary hypothesis test mode of level quantification detection, high positioning performance is possessed.
Description
technical field [0001] The invention relates to the field of wireless sensor network positioning, in particular to a wireless sensor network three-dimensional positioning system. Background technique [0002] As a new information acquisition and processing technology, wireless sensor network has broad application prospects in target tracking, intrusion monitoring and some positioning related fields. In daily life, people often need to obtain services based on location information instantly through terminals. For example, before entering the shopping mall, you can find a parking space through the terminal navigation guidance; during the shopping process, if you search for "food", you will be presented with store discount information based on location and orientation, and you can get the best route guidance. [0003] However, no matter in applications such as geographical environment monitoring or final navigation guidance, or in traffic road condition monitoring or patient t...
