Vehicle-born wireless energy transmission device

In order to monitor technical status of vehicle-born rotational device, it is necessary to power monitoring unit wirelessly. The transmission and receiving module of wireless energy-transmission device are designed and smallest system of monitoring unit is devised by using low-power. Determine optimum resonant frequency of the transmission module through testing the strength of the received signal and the number of paring antenna by the minimum energy received by different rotation angle to ensure the monitoring module to work properly. Experimental results show that the wireless energy-transmission device can power the low-power monitoring unit and complete functions of data acquisition and wireless information transmission.
