Abstract

In order to solve the security and maintenance problem of the sensors in harsh petrochemical environment

application of wireless power transmission in multi-sensor system is researched

physical mechanism and mathematical model for wireless power transmission are analyzed

and influence of coupling parameters on power and efficiency of system transmission is obtained.In ANSYS finite element software

model for wireless powered sensors with single transmitter coil and triple receiving coils is established.A parametric sweep of Lateral migration

vertical migration

excitation frequency are obtained

and the influence of relative position variation between coils on system coupling parameters and change of extication frequency on power transmission efficiency are derived.The wireless power transmission experimental platform with single transmitter and triple receivers is designed

which realizes the wireless power supply to SENSOR-PUCK.The experimental results verify feasibility of the designed wireless powered multi-sensor system

which has a guiding effect on the practical application of wireless power transmission technology in sensor field.
