But, it will be appreciated by those skilled in the art that, conceive based on above-mentioned hardware, those of ordinary skill in the art, also software simulating correlation function can be adopted, such as: to main control chip Embedded Operating System, and carry management software, on standardization, informationalized basis, information is effectively managed, and exactly the geologic parameter that linkage sensors is uploaded is judged, if exceed setting threshold value, start joint-action mechanism, make by linkage sensors encryption sampling, guarantee can not to critical data " leakage be adopted ".In addition, the funtcional relationship between the model construction of disaster body and each parameter can also be built, thus the harmfulness of effective alleviation geologic hazard and the sudden loss caused.
The above-mentioned monitoring carried out based on software, can in the following ways:
Linked system is primarily of the automatic monitor station of collaborative support, central server and interlock dispatcher composition.
Normality: trigger monitoring station and wait for trigger pip and timed sending safety datagram (as rainfall monitoring station, surface displacement monitoring station); Query formulation monitoring station adopts timing inquiry collection to report with the count off of timed sending safety according to (as survey stations such as deep deviational survey, water percentage, soil moisture contents) (4 hours or 6 hours); Controlled collection monitoring station adopts timing acquiring and acceptor center controllers to control to gather (as video surveillance station).
Warning triggering can trigger interlock by trigger-type monitoring station or query formulation monitoring station.Disaster body monitoring station is encrypted collection as generation alerting signal then triggers joint-action mechanism.Wherein, joint-action mechanism sets according to actual needs.As: soil moisture content monitoring station produces alerting signal, corresponding our station and relevant monitoring station survey stations such as () deep deviational survey, liquid levels enters linkage status and is encrypted collection.When after alerting signal disappearance certain hour, interlock monitoring station is according to joint-action mechanism delay recovery normality.
Also can adopt and manually enter linkage status: namely, when user carries out remote interlocking configuration to monitoring station time, each monitoring station corresponding enters linkage status, when control signal is for recovering control signal, after alerting signal disappears, interlock monitoring station returns to normal according to joint-action mechanism.
Interlock communication channel: when the signal that links occurs, first central server detects treats interlock monitoring station whether online (GPRS), treat interlock monitoring station and carry out interlock configuration, if not online, then carry out remote call-in by interlock dispatcher to wake up, if central server finally can't detect the presence treating interlock monitoring station, then by note form, remote interlocking configuration is carried out to monitoring station by interlock dispatcher.The attribute information reporting oneself current after the configuration successful of monitoring station.
In the utility model, this equipment of linked system is equivalent to the dispatching center of all the sensors node, with rainfall and surface displacement for inducement start-up parameter, wakes up in time and collection density under formulating present circumstances to involved sensor nodes.Additionally by Software for Design, the parameters such as the stability factor of disaster body, probability of survival, rate of deformation, displacement, acceleration, Critical Rainfall are defaulted in this instrument, the difference of environmentally condition in disaster monitoring can be realized and corresponding change occurs.
Concrete, the utility model achieves multiparameter exponential family, sensor node interlock is got up, and predeterminable alarm level and monitoring contextual model, energy management is carried out to field low-power consumption sensor node, especially abnormal triggering adds interlock encryption and gathers and build the new method of Geological Hazards Monitoring system, implement continuously to geologic hazard, in real time, dynamic monitoring, the comprehensive and accurate data of timely acquisition, meet the requirement of robotization, thus assist the geologic hazard vocational work of regulatory authorities can efficiently coordinate to carry out, pre-Geological disaster prevention occurs, reduce the loss of lives and properties.
The above is only preferred implementation of the present utility model; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should look protection domain of the present utility model.
