Device and method for identifying mine shaft water invasion resource based on laser induction and SIMCA classification method

The invention discloses a device and a method for identifying a mine shaft water invasion resource based on laser induction and an SIMCA classification method. The device comprises a laser device, an immersion probe, optical detectors, an optical spectrum analyzing module and an identification module, wherein the laser device is connected with the immersion probe by virtue of optical fibers; the laser device is used for transmitting laser into tested water of a water gushing point; the tested water is subjected to stimulated radiation to emit fluorescence; fluorescence signals are received by the immersion probe in real time and are transmitted to the optical detectors by virtue of optical fibers; the at least two parallel optical detectors are used for respectively reading the fluorescence signals of predetermined wave bands at the same time; the optical spectrum analyzing module is used for carrying out filtration and A/D conversion according to the fluorescence signals output by the optical detectors; fluorescence spectrum data of an integral wave band is output after the data is integrated; the identification module is used for judging which known water sample the tested water belongs to according to the input fluorescence spectrum data of the tested water and a PCA model of the known water sample based on the SIMCA algorithm. The device and the method are used for implementing timely and accurate on-line identification of the type of a water source.
