Debris flow early warning system based on mudflow parameter monitoring and early warning method thereof

The invention discloses a debris flow early warning system based on mudflow parameter monitoring and an early warning method thereof. The system mainly comprises a power supply formed by a solar cell board, a main storage battery and an auxiliary emergency battery; a rainfall recorder used for monitoring rainfall capacity of the area where the device is arranged; a mudflow flow rate meter, a mudflow flowmeter and a mudflow densimeter, which are used for monitoring flow rate of the loess mud flows and proportion of mud carried by the loess mud flows; a CPU which is used for receiving data detected by the rainfall recorder, the mudflow flow rate meter, the mudflow flowmeter and the mudflow densimeter, processing the data via a transportation processor, comparing the processed data with the pre-determined critical threshold value and then making judgment; and an alarm formed by an indicator lamp and a sound alarm. In this way, according to history mudflow data, combining characteristics of the loess mud flows and the starting conditions, the corresponding model is established, the corresponding clinic threshold value is calculated and all data are obtained via calculation rather than experimental parameters, so the system and the method are scientific and precision for early warning of debris flows can be effectively increased.
