Embodiment Construction

[0033] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0034] see Figure 1-4 , the rainstorm type dilute debris flow monitoring, forecasting and early warning device of the present invention includes the following units:

[0035] Multi-element weather station unit 4: Six-element configuration equipment is used in the rainstorm-type dilute debris flow monitoring, forecasting and early warning device. The equipment mainly includes monitoring equipment such as rainfall collection, wind speed sensor, wind direction sensor, temperature, air pressure and humidity. The power supply method is mainly based on solar cells, and at the same time additional rechargeable batteries.

[0036] Mud water level alarm unit 5: It is composed of data acquisition alarm instrument, laser level probe, alarm sound, computer and so on. The laser level probe is a non-contact measuring instrument with strong anti-interference ability. It ...

Abstract

The invention discloses a heavy rain type diluted debris flow monitoring, forecast and early warning device and method. The device comprises a multi-factor weather station unit, a muddy water level alarm device unit and a video monitoring device unit. When rain falls on a debris flow formation region, the multi-factor weather station unit starts to collect rainfall data and transmits the data to a far-end comprehensive control center; when rainfall reaches or exceeds critical rainfall value for debris flow formation, first time early warning and forecast signals are sent out; when debris flows converge into upper and middle reaches of a main trench and exceeds safety threshold value and critical mud level threshold value, second time alarm signals are sent out; when the debris flows reach upper and lower survey sections of a preset position and exceed critical value, emergency alarm signals are sent out, returned data is analyzed and processed via computers by the comprehensive control center, a data curve us drawn on line in real time, data storing operation is performed, and a comprehensive forecast and early warning solution is issued according to forecast and early warning signals of all monitoring areas. Via use of the heavy rain type diluted debris flow monitoring, forecast and early warning device and method, rainfall, muddy water level and video data can be automatically collected, recorded and processed; efficiency can be improved.

Description

technical field [0001] The invention belongs to the field of geological disaster monitoring, and specifically relates to a rainstorm type dilute debris flow monitoring, forecasting and early warning device and method. Background technique [0002] The impact of mountain torrent (debris flow) disasters has expanded from past agriculture to many fields such as cities, industries, and ecological environment. Mudflow is a common geological disaster in the Loess Plateau. It erupts suddenly, comes fiercely and quickly, and has strong destructive power. It has caused serious harm to the industrial and agricultural production and people's lives in the Loess Plateau. Sudden mudflows often rush into villages and towns, destroying houses, factories, enterprises and institutions, and various equipment and facilities, and also burying people, animals and farmland, and even causing villages to be destroyed. Imminent monitoring and warning, that is, the forecast within zero hours to sever...
