Abstract

Because of the high degree of railway’s electromagnetic radiation and the vulnerability of the traditional electronic sensor, the safety monitoring of railway’s protective net in slopes is an important process. Based on fiber grating’s such advantages as freedom from electromagnet, and the convenient linkage of signal, this thesis formulated tension sensor and acceleration sensor on the basis of protective net’s characteristics. By conducting the impulse test on the protective net that is installed with sensor, we collected the mechanics’ parametric variation during the whole process of impact. The fiber grating sensor used in the test was stable and reliable.
