(EN)
The utility model discloses a distributed optical fiber vibration sensing real -time data processing device, the device include photoelectric detector, signal amplifier, data collection station, dataprocessing module, synchronization signal interface, signal output interface. Photoelectric detector plans the signal of telecommunication with the light signal conversion moulding that distributed optical fiber vibration sensing system returned, inputs among the data collection station after signal amplifier enlargies again. Data processing module gathers according to synchronization signal interface type's synchronization pulse signal control data collection station, and the analog signal transition after being enlargied signal amplifier by data collection station becomes data signal to handle in inputing data processing module, obtain effectual vibration signal data, carry through the signal output interface at last and advance line display and storage in the computer. The utility modeldiscloses technical scheme will improve system data treatment effeciency and response speed, also increase the data -handling capacity of system simultaneously.
