Abstract

The invention relates to an intelligent multichannel fiber bragg grating (FBG) online backup system, which comprises an upper computer, an FBG signal processor host, an FBG signal processor standby machine, a hot spare switch module and a sensor module, wherein the sensor module is connected with the hot spare switch module through a transmission cable, the hot spare switch module is connected with the FBG signal processor host and the FBG signal processor standby machine through optical cables, the FBG signal processor host and the FBG signal processor standby machine are respectively connected with the upper computer so as to transmit a demodulation signal, and the hot spare switch module is connected with and controlled by the upper computer. The intelligent multichannel FBG online backup system adopts two sets of system hot engine backup and can realize automatic intelligent switch, thus being convenient for use and having high reliability.

Description

technical field [0001] The invention relates to optical fiber sensing technology, in particular to an intelligent multi-channel optical fiber grating online backup system. Background technique [0002] As a new type of sensor, the fiber grating sensor has a wide range of applications. Such sensors can be used to measure multiple physical quantities including strain, stress, temperature, vibration, displacement, acceleration, current, voltage, magnetic field, frequency, and concentration. The biggest advantage of the FBG sensor is that it can realize multi-point measurement and obtain relevant physical quantities to achieve the purpose of alarm and fault diagnosis. [0003] Since the 1970s, it has been widely used in petroleum, electric power, transportation, bridges and other fields due to its advantages of small size, high sensitivity, no electromagnetic interference, high reliability, low cost, easy integration and ambush measurement. Its industry has been recognized as ...
