Constructing a wireless chargeable sensor network based on the magnetic coupling resonant technology realize the wireless charging of the sensor nodes all the time,and slove problem of energy limitation possibily.In the wireless chargeable sensor network,a enCar node carries the limited energy,design of the SenCar node and its energy distribution are directly related to the energy transmission efficiency and its network stability.Therefore,it is important to optimize the network utility and extend the life cycle of the network by designing SenCar node,combining network characteristics and constructing the energy distribution model.In the wireless chargeable sensor network based on one-to-one magnetic coupling resonant,a mobile charging SenCar node is set up and its energy is distributed from the energy needs,magnetic coupling energy transmission,network data transmission and other needs.The main work is as follows.Based on functional requirements of the SenCar node,design requirements of hardware and software and structure of the SenCar are put forward.According to the requirements,hardware and software design as well as the structure design are realized.The hardware is configured with energy monitoring module;function of periodic monitoring of its own energy information is achieved through software scheduling.According to the characteristics of uneven energy dissipation,a charge-on-demand-periodically(CODP)scheme is proposed according to energy of SenCar itself charging power of SenCar nodes and the wireless energy transmission efficiency of SenCar nodes.In this scheme,a number of charging intervals are built,the charging nodes are allocated to each charging section,and each section is charged with one round.Construct the shortest Hamilton loop to reduce moving distance and energy consumption of the SenCar node in every round.A simulation is carried out from the balance degree of remaining energy of sensor nodes and the energy limitation.The simulation results show that the CODP balances the remaining energy of sensor nodes and improves the network efficiency.
