磁感应供电多路温度变送器的设计

The design of a multipoint temperature transmitter powered by magnetic induction

介绍了一种针对旋转物体的多点温度测量方案。测温电路由旋转部分和静止部分构成,旋转部分采用无线磁感应供电,温度脉宽调制光脉冲发射送至静止部分光电接收器件,由单片机完成PWM脉宽至温度的转化,并通过串行通信实现与外界的通信。

This paper presents a method to measure the multipoint temperature of a rotaung object. The measurement circuits comprise a stationary part and a rotating part. The rotating circuit is widelessly powered by magnetic induction, which can output a train of temperature PWM light pulse. A programmed MCU transfers the PWM pulses into temperature data, which can transmitted through serial communication.
