Wireless Temperature Acquisition System Based On ZigBee Tecnology

The use of self-organizing network of ZigBee technology and wirelesscommunication features, we design an object moving along with the measuredtemperature acquisition system, the temperature of the system collection terminalnetwork in the system within the effective range of collection temperature, known as theline Mode. Radiation can also be outside the scope of the network to collect temperature,when you enter the network coverage of the monitoring center, the temperaturecollection terminal can be previously stored in the FLASH chip temperature informationusing a wireless network upload first bit machine, known as off-line mode. Use the PCto display the historical data.This paper briefly describes the wireless temperature acquisition systemarchitecture and the basic principles of the terminal nodes, the development of theoverall system design, the selection of sensors; completed the acquisition sensor nodes;terminal cluster node module; and control module of the software and hardware design.Cygwin software system selected terminal nodes and coordinator nodes programming,using Visual Studio2008PC monitoring software for the design, preparation of a serialcommunication program, in order to achieve the temperature control of biological visualmanagement.Finally, test network performance. The temperature acquisition node work in lowpower mode, on this basis, calculated by testing the entire network under theperformance of the system obtained in the low-power mode, the communicationsequipment from the single-hop data transmission, communications equipment, a singleHop data transmission delay, network communications equipment by means associatedwith the time required to fully meet the temperature data acquisition wireless network.The experiments prove the feasibility of the design. Paper at the end of the textsummarized, and the research work carried out under a prospect.
