Research On Wireless Sensor Network Nodes Photovoltaic Energy Harvesting Technology

Along with the Network technology, communication technology and the rapid development of computer technology, Wireless Sensor Network technology, Wireless Sensor Network, WSN) arises at the historic moment. Wireless sensor network(WSN) is to decorate a large number of sensor nodes in the monitoring area of multiple hops network system, to collect environment information and the information will be collected to the network owner. At present has been used in many fields, playing the human and other monitoring system has an irreplaceable role.And the development of WSN is influenced by its main technology, among them, the first is power consumption. Standard power consumption problem has carried out related research. Designed for Qinghai sanjiangyuan need no man’s land, such as wireless sensor network node, in terms of the selection of hardware, on the premise of guarantee the normal work of the node, from the perspective of reducing power consumption, done a lot of simulation experiment and contrast, finalized CC2530 and 8051 as the main components of the circuit.USES the dormancy in energy management, to reduce the duty ratio and data fusion technology to reduce the power consumption of the sensor network nodes, and also some other low-power strategies are put forward. Finally, the sensor node power supply module focus on analysis and research, the hybrid energy storage system is proposed and the related experiments, the feasibility of the system are obtained.In this paper, the main nodes in wireless sensor network power supply mode and low-power strategy has carried on the experiment and research, the low-power strategy is obtained and the design of the power supply module can satisfy the similar source unmanned region of Qinghai province in the environment sensor nodes to work normally, the conclusion and envoys to get a degree of extended service life. Has certain research value and significance.
