Research On EnOcean Energy Harvesting Mechanism And Low Power Technology

In recent years, with the monitoring and management system of construction, residential demand of wireless technology rising and effectively for wireless sensor networks to provide energy and reduce. energy consumption is the designer needs to consider the important issues.The key to prolong the lifetime and save the cost of the wireless network harvester is the energy saving of the nodes of the wireless harvester and the power supply, that is the problem of energy consumption and energy consumption.In the vibration energy harvesting and conversion proposed Euler Bernoulli beam pressure model of cantilever, for self excitation micro force harvester for coupling, makes the optimized improvement to the energy harvester for energy and in energy harvesting can be energy conversion into electrical energy storage, and generate a harvester for harvesting nodes energy in the energy consumption is analyzed. Power source characteristics of WSN nodes need to many network nodes, low power nodes, node points scattered, needs to spread out the power supply, the lifetime of the network relies on the node power supply etc., wireless harvester for network nodes with low power dissipation makes harvesting energy self supply technology possible, EnOcean energy harvesting techniques in nature, from the harvest of the weak energy, also emit wireless signal, receiving to drive equipment. The energy harvesting method of the wireless harvester network is studied in this paper.The EnOcean energy harvesting technology mechanism and method are analyzed. The solar energy, vibration energy, magnetic energy and temperature difference can four energy harvesting approach for energy harvesting. In the complex environment, sensor nodes can use a variety of methods to obtain energy from the nature, in order to ensure that the sensor nodes can work stably.The low power consumption protocol of wireless sensor network is adopted to reduce power consumption.. In sensor network MAC layer protocol design, mainly through for node sleep to save energy, MAC layer protocol for node wake-up and sleep time design, to ensure that the target node not in dormant period missing data received, focusing on wireless sensor network energy efficient routing protocol, LEACH protocol is one of the basic ideas is in each sensor node in the average share of the whole network energy load, reduce the network energy consumption, and increase the survival time of the network’s overall. DEEC algorithms based on the average energy of the residual energy of nodes and network to the election of cluster,node residual energy more become cluster head of the greater the chance, the algorithm can be very good to balance the network energy consumption. In the MATLAB, the LEACH protocol and DEEC protocol are simulated, and the two protocols are compared.. In this paper, the energy harvesting technology of EnOcean and low-power technology can be added more features of sensor network, wide application, broad prospects.
