Application And Study On Self-power Supply And Ultra Low Power Wireless Sensor Network

Wireless sensor networks with its easy to expand, invulnerability, high precision, wide coverage area, the application of high flexibility and other unique advantages, more and more people pay attention, continue to make its research breakthrough, the The range of applications is the rapid expansion of the production life of the human society has penetrated into almost all areas and levels of current research and application of wireless sensor networks.But the reality of deployment and application environments are often very complex, even toxic, harmful, staff simply hard-to-reach places, the scene node in this case to replace the battery, or charge the field wiring is difficult to achieve node finite energy consumption do not supplement will automatically exit the network, which directly affect the realization of life and survival of the network as a whole functions, which greatly limits the range of applications of wireless sensor networks for network nodes to provide long-term stability of energy has become the problem can not be ignored, also by the people more and more attention and study, on a broad basis of the relevant research results at home and abroad, the paper proposes a "ultra-low power consumption, the concept of self-powered wireless sensor networks from the energy and independent power generation two ways to solve the problem of network energy ideas:in energy efficiency, the energy consumption of wireless sensor networks is analyzed to find the distribution of energy consumption of each module of the network nodes, hardware selection principle to the ultra-low power consumption as a precondition and based on the difference in energy consumption in the node module under different working conditions, the focus of the most user-friendly sleep mechanism for energy conservation research and simulation testing; independent power generation, generally in the outdoor environment for wireless sensor network deployment, the surrounding Most of them are, this feature can take advantage of the natural energy and environmental energy, such as solar, hydro, wind, heat, pressure, and ideas combine the actual deployment occasion, collect environmental energy independent power generation in the brief introduction to the traditional natural based on energy harvesting, focusing on the use of on-site waste heat, temperature tail thermal power generation thermoelectric power generation were discussed in relevant practical applications to heating household heat metering system as an application object, the introduction of wireless sensor networks and achieve its ultra low power consumption, and the idea of self-powered, study design self-powered wireless sensor networks of ultra-low-power household heat metering, using no flow heat metering method, in accordance with the ultra-low power consumption required to complete the selection of hardware, communications and energy saving design and related circuit design, the power generation module of the design, select a heat pipe cooling way cold end of the cooling, and heat dissipation through experiments generating effect, with natural convection cooling.conducted a comparative analysis, draw the heat pipe heat way The effect of the advantages of thermoelectric power generation, as well as a module efficiency of power generation and temperature difference between the final completion of the commissioning of the overall software programming and system of independent power supply part of thermoelectric power generation modules, energy storage component selection design, and related modules.
