According to the limitations of the existing self-diagnosis and self-repairing system for optical fiber smart structure, a system of remote data communication for liquid-core optical fiber smart structure based on ARM and GPRS is proposed. The system mainly consists of laser source, liquid-core optical fiber smart structure, microcontroller, GPRS communicate module, light source using for repairing, internet and monitoring center. The liquid-core fiber optic smart structure is made up of the special liquid-core fiber embedded into composites. The system uses the GPRS wireless communication technology, combining with the core processor S3C2440 ARM embedded technology. And in monitoring center, a visual surface software is designed using Microsoft VB. It has the advantages of intuitive and trustiness. Meanwhile, the experiment of loading is carried out. And the data of experiments are analyzed by BP network theory. The research results show that the monitoring system is stable, efficient and reliable and the position of loading can be located exactly.The composite self-diagnosis is realized preliminary.
