| Abstract: | A new type of automatic automotive load detecting system based on FBG was introduced for freeway. As the center wavelength of FBG was changed linearly under the external pressure, by detecting the changes of FBGs' center wavelength under the pressure of vehicle, the weight of the vehicle could be measured. This system could detect real-time and possess the advantages of high precision of detecting, anti-electromagnetic interference and high detecting efficiency. |
