The Wounded Perception And Rescue System Based On The Sign Sensor Networks

The sign sensor network based wounded perception and rescue system which can be divided into perception layer, transmission layer and application layer on the system architecture. The perception layer is hardware system layer, mainly composed of signs sensor nodes which can gather information signs(such as pulse and temperature),including sign sensor nodes,sign sensor acquisition nodes,BAN coordinator and compass chips. The transmission layer is transport protocol layer, the main function is realizing the entire data transmission in this system. First of all, sign sensor acquisition nodes gather all the signs sensor node data.Then the BAN coordinators gather all sign sensor auquision nodes data and merge the data in an array. Array data is sent to the sink node by multi-hop.Finally,the data is sent wirelessly to the software system. The application layer is the software system for computing all the system data.The main contributions of this thesis are as follows:1.In order to avoid the shortcoming of previous sign sensor node in this system(such as obtain data,big size,power uncontrolled),a universal transceiver module based on Zigbee and serial port is designed. On this basis,design a sign sensor acquisition node.In addition,needing to chose the type of sensor node,design BAN coordinator, use compass chip.2.In order to guarantee the system work, a remote monitoring method based on the body area network was designed in this thesis. The method choosed Zigbee as the communication protocol, which can make good use of this system in various conditions.3.Developed a osm offline map system, data management client, inquirement and rescue decision-making system, which realizing the integrated design of data inquirement, sign monitoring, data management, rescue decision-making and network control.The center of this system is monitoring the wild battle sign, which can be widely applied to military, disaster rescue, high-risky and special profession emergency, perceiving and rescuing the wounded. This system had achieved good economy and society benefits.
