Mud-rock flow early warning system

Abstract

The invention discloses a mud-rock flow early warning system, which mainly comprises five to eight mud water level probes, a rain gauge, a data acquisition alarm, a computer, a power battery and an electric alarm, wherein the mud water level probes are embedded in the sidewall of a mud-rock flow guide channel on a monitored scene and uniformly distributed according to the height; the rain gauge is arranged in a range of a mud-rock flow monitoring and observation field; the electric alarm is arranged at the top of an observation room; the data acquisition alarm, the computer and the power battery are arranged in the mud-rock flow observation room; system software is arranged in the computer; when the mud water level probes are immersed in water or saturated mud water, signals are respectively sent and transmitted to the data acquisition alarm, and an alarm sound is sent and transmitted to the computer; after detecting rainfall information, the rain gauge sends the rainfall information to the data acquisition alarm; and the data acquisition alarm calculates accumulated rainfall amount and then transmits the accumulated rainfall amount to the computer. The mud-rock flow early warningsystem is used for monitoring mud water level in real time in the initial stage of occurrence of mud-rock flow, displaying the corresponding mud water level, rainfall amount and rainfall intensity, and giving an alarm.

Description

technical field [0001] The invention belongs to a monitoring and early warning technology, in particular to a debris flow early warning system. Background technique [0002] Monitoring and early warning of debris flow can ensure the safety of life and property of residents in downstream cities and villages where debris flow occurs. [0003] At present, the group monitoring and group prevention monitoring and early warning technology for sudden geological disasters (especially for debris flow monitoring and early warning) popularized and applied in my country is mainly based on manual patrol inspection and monitoring, including pile-burying method, nail-burying method, painting method, pasting method, etc. Since 1998, many geological disasters have been successfully avoided nationwide, and the relevant people have been transferred in time, which has played its due role. However, its weakness is that the monitoring and alarming technology is relatively backward. In this situati...
