According to the property of GPRS network transmission, wireless remote data transmission technology is applied to the monitoring data of fiber Bragg grating, through the GPRS network to transmit the FBG monitoring data to data monitoring center, in the numerical control center can understand the monitoring site information, in order to achieve real-time monitoring of timing, automatic, unattended. In this paper we introduced the system structure design of the FBG monitoring system, We discussed the software of the wireless remote data transmission and the data pretreatment. As a result, it is suited that use GPRS wireless communication mode to realize the grating remote transmission of monitoring information is feasible. Index Terms - GPRS network, Wireless Remote Data Transmission, FBG monitoring system. I. Introduction GPRS (General Packet Radio Service) is based on GSM network, and to provide users with the network service of high-speed packet data. In recent years, with the continuous optimization of GPRS network, network quality is enhanced unceasingly, GPRS is increasingly used in various industries. GPRS has many advantages, such as: high resource utilization, large network coverage, network access speed, high transmission speed and support a variety of transport protocols, etc. Compared with traditional railway network, it has incomparable advantages, it can completely meet the needs of the fiber Bragg grating remote long-distance monitoring. Therefore, it is great significance that wireless remote data transmission technology is applied to the grating monitor to realize automation for the monitoring and control of fiber Bragg grating |
