Device.
The utility model additionally provides a kind of debris flow early-warning method, based on above-mentioned debris flow early-warning device, it include with
Lower step：
A, it is arranged at intervals multigroup debris flow early-warning device along hillside short transverse on the hillside that mud-rock flow easily occurs：Every one
Fixed height sets one group of debris flow early-warning device, has at least one debris flow early-warning as needed in one group of debris flow early-warning device
Device, should be at during the installation of this group of debris flow early-warning device on sustained height and separately a certain distance when setting multiple.
B, the CPU1 in each debris flow early-warning device is with the defeated of 4Hz -20Hz frequency collection 3-axis acceleration sensor 3
Go out, and data are sent to background server by data communication module 4；A value can be set in this step, only when three
The output of axle acceleration sensor 3 just sends data by data communication module 4 more than the value of setting to background server.Tool
Body, global array is established in this step, and CPU1 calculates 3-axis acceleration sensor 3 and collects three axles output physics conjunction value a
[i] and physics conjunction value a [i] is transferred to background server, wherein a [i]=If a [i]>5kg/
m2, then the probability that mud-rock flow occurs can be big.When there is mud-rock flow generation, debris flow early-warning device first it is detected that be to have vibration,
Then 3-axis acceleration sensor 3 detects big physics conjunction value after whole pile body is destroyed.
Whether it is mud-rock flow that the data and time interval that C, background server transmits according to debris flow early-warning device are concluded.From the background
Server collect multiple parameters judge whether be sensor social event, if the incident of single sensor then may be used
Wrong report early warning is excluded, so as to more accurately make disaster alarm, and by the data analysis and modeling to sensor, can be predicted
The direction of mud-rock flow and the earth volume size that mud-rock flow occurs, so as to which the rescue for disaster and assessment provide strong data.
Background server can first determine whether the value that this group of debris flow early-warning device in sustained height is exported, and work as major part
Or whole 3-axis acceleration sensors 3 collect three axles output physics conjunction value a [i]>5kg/m2When then judge to might have mud
Rock glacier occurs, and can send alarm signal to the warning device at hillside, otherwise records this event and notifies local employee to carry out
Check, detect debris flow early-warning device in scene；When server judges to might have mud-rock flow, and background server obtains
The physics conjunction value exported along every group of debris flow early-warning device at hillside short transverse interval gradually increases and time interval gradually subtracts
It is small, then judge mud-rock flow occurs.
Finally it should be noted that：The above embodiments are merely illustrative of the technical scheme of the present invention and are not intended to be limiting thereof；To the greatest extent
The present invention is described in detail with reference to preferred embodiments for pipe, those of ordinary skills in the art should understand that：Still
The embodiment of the present invention can be modified or equivalent substitution is carried out to some technical characteristics；Without departing from this hair
The spirit of bright technical scheme, it all should cover among the claimed technical scheme scope of the present invention.
