Abstract: A method for desiging the software of FBG sensor network in the VB language environment was introduced to compile the software for serial communication based FBG sensor network conveniently and achieve the long-distance control of the FBG sensor network. The serial communication between PC and SCM in the environment of VB programming language, the control of the PC to the SCM, the data processing and figure drawing were implemented. The accuracy and feasibility of the FBG sensor network based on the tunable laser demodulation method and its analyzing software were verified by the calibrated FBG. The result of the experiment shows that the software is easy to design and it works reliably. A new solution for the remote control and the network control of the fiber grating sensor network is presented.
