2.-2, first microcontroller judge the ripples in the setting-up time section obtain amplitude peak whether less than 0～0.4V, if, then think ripples relatively placidity in the water environment of sensing device work at present, execution in step 2.-4 then; Otherwise, first microcontroller judges whether the cycle of the ripples that obtain is infinitely great, if, then think the irregular variation of ripples in the water environment of sensing device work at present, execution in step 2.-4 then, otherwise, think that the ripples rule changes in the water environment of sensing device work at present, execution in step is 2.-4 then;
Wherein, the setting-up time section is 60～180ms;
2.-3, first microcontroller carries out corresponding the comparison to the amplitude peak of the ripples of each the special waters model in the FLASH storer that is pre-stored in first microcontroller, cycle and the amplitude peak of the ripples that obtain, the cycle of ripples of ripples, if the difference of the amplitude peak of both ripples less than the difference in the cycle of 1.5～2.5V and both ripples less than 40～220ms, think that then qualified special waters model is the waters model of current coupling, and continue execution in step 2.-4, otherwise, the closed front end flip flop equipment;
Wherein, special waters model comprises normal tour swimming pool waters model, pond water domain model, river waters model, the thermal water domain model under the adverse weather condition;
2.-4, first microcontroller determines that the water environment of sensing device work at present conforms to the waters model of current coupling;
3. first microcontroller is according to the digital voltage signal of the current 2 second time period of storing in the instant data storage area, the amplitude peak of ripples in the water environment of sensing device work at present and the cycle of ripples are obtained in analysis, and to the amplitude peak of the ripples that obtain, the amplitude peak of the ripples of the waters model of the cycle of ripples and current coupling, the cycle of ripples is carried out correspondence relatively, if the difference of the amplitude peak of both ripples less than the difference in the cycle of 2.5～3.5V and both ripples less than 200～1000ms, then returning step 3. continues to carry out, after reaching 150 times, number of comparisons returns execution in step 1., otherwise, first microcontroller produces alerting signal, and transmitting alerting signal to first alarm module and radiofrequency emitting module, first alarm module is reported to the police according to alerting signal;
4. radiofrequency emitting module transmission alerting signal is given Receiver Module, and Receiver Module transmission alerting signal is given second microcontroller, and second microcontroller is controlled second alarm module according to alerting signal and reported to the police.
