正交试验方法在轮胎内置式智能传感器自供能系统的应用

Application of Orthogonal Experiment Method in Self-Energy Systems of Built-in Intelligent Sensors in Tires

介绍基于RFID的轮胎内置式智能传感器自供能系统。针对系统发射端和接收端在规定的间距下,难以达到所要求的输出电压的问题,利用正交试验方法,在发射端和接收端寻找合理的RLC组合。通过实验得到:在输出频率f=125k的条件下,发射端电阻值为1?、发射端和接收端电容值均为10nF这一组合可使系统输出电压最大。

A self-energy system of built-in smart sensors in tires is introduced. Under the provisions pitch between the transmitter and the receiver, the output of voltage cannot reach the required value. A reasonable combination of RLC of the transmitter and receiver by orthogonal experimental method is put up in this paper. Experiment results show that when R=1Ω, the transmitter capacitance C=10nF and the receiver capacitance C=10nF, the output voltage gets maximum under the frequency of the output= 125k.
