Research On Monitoring System Applied To Large-scale Birds Migratory Route

Many countries have an outbreak of Avian Influenza at different degree and burstingperiodically during the past few years, it causes serious harm to economic development,social stability and human health. Scientific research has showed that bird migration hadclose connection with the eruption. Study on flu epidemic situation has become countriesresearch emphasis. Therefore, many research institution all over the world focus on birdmigratory route study, objective is to offer help and guiding for Avian Influenzaprevention and control.In this paper a research system used to study bird migratory route was proposedbased on the research background, this system is structured by tracing node and monitorserver, based on GPS(Global Positioning System) and GPRS(General Packet RadioService) technology. Binding the node to test bird, sampling its position information oncea certain time, the node send all collected data to monitor server through GPRS networkwhen acquisition data reach prescriptive capacity. Meanwhile, the server receive datacomes from the node, classify and storage, then we can predict the characteristics ofmigration after data analysis and processing.The design criteria of tracing node is small volume, low weight and low power,using ultra-low power consumption processor, clipping redundant components furthest,ensuring high integration during the process of design. The node must implement datacollection, storage and sending successively, using fixed cycle data acquisition mode,acquiring a set of data once sampling period, the node is in the dormant state during themost residual time, decreasing power consumption farthest. In addition, the value ofsample period can be modified by server. collected data is stored in Flash constantly, itwill awake the system and prepare for sending when data quantity meet the requirements,node send data according to consultative data format(node–server communicationprotocol for positioning data). Meanwhile, responding control command actively.The monitor server implement data receiving, storing, querying and node control.The system including basal information manager model which realizes user management,node registration and management, positioning data receiving and storing model which implements normal data receiving and storing through the result of data unpacking, nodequerying model which ensure user acquire positioning data, node usage information andcontrol information, furthermore, tracing state model which can analysis that workingstate of nodes(valid or in valid), then modifing state parameter on purposes of efficientsystem monitoring.Combining test node with the server perform comprehensive test for sake ofverifying design results, Finally, test result show that it is consistent with designrequirement, according to designed testing scheme. The node can collecting and sendingdata accurately, also can collecting and storing data during the waiting time for tryingagain to sent data even if the network is invalid, At the meantime, responding controlcommand from server, the result aslo show that the server can complete data receiving,storing and the task of state controling.
