胎压检测系统中的非接触电能传输技术

传统电能传输主要通过导线直接接触,在一般情况下该方法合理有效;胎压检测系统通常由检测模块和中央模块构成;其中,检测模块被置于轮胎内部,实现压力的检测和数据的传输;因此,在隔离并且高速旋转的情况下,传统电能传输方式有很大的局限性;非接触电能传输系统由能量变换和发送回路和能量接收回路组成,利用电磁感应与耦合原理实现能量传输;本文根据非接触电能传输原理,设计了一种基于可旋转变压器的非接触电能传输装置,实现了对检测模块的供电和电能的无接触传输。

Application of Contactless Power Delivery Technique in Tire Pressure Monitoring System

Most electrical equipments get energy through plugs from source,and have been accepted widely.Tire Pressure Monitoring System encompasses two major parts,including Monitor modules and Central modules.Monitor modules are fixed on each tire to examine the pressure inside,and then send data out.The traditional way to deliver energy has many weaknesses on this condition.The contactless power delivery system is composed by power transfer system and power receiver system.It is based on the principle of inductive power trans- mission and can be widely used in the contactless environments.The basic principle of the contactless inductive transmission is given,and a equipment based on rotor converter is designed to deliver power to the Monitor modules.
