Rainstorm early warning and monitoring method and system for remote mountainous area

Abstract

The invention discloses a rainstorm early warning and monitoring method and system for a remote mountainous area. The method specifically comprises the following steps: step 1, data acquisition and analysis; step 2, graded monitoring; step 3, information summarization; and step 4, manual observation. The invention relates to the technical field of disaster prevention and reduction of rainstorm and mountain torrent disasters. According to the rainstorm early warning and monitoring method and system for the remote mountainous area, effective early warning of rainstorm torrential torrents in the mountainous area is achieved by means of cooperation of automatic detection and manual detection, the situation of missed alarm is effectively avoided, data of torrential torrents outbreak over the years in the river reach are sorted, the rule of the torrential torrents happening to the corresponding river reach is found, and the early warning efficiency is improved. According to the method, the sudden change value of the river reach liquid level is taken as early warning data, early warning can be effectively realized, so that an excellent early warning effect is ensured, the existence of a great mountain torrent abnormal risk is judged by manually checking the abnormal identifier, the successful sending of early warning information is ensured, and time guarantee is provided for emergency evacuation of personnel.

Description

technical field [0001] The invention relates to the technical field of early warning and monitoring, in particular to a rainstorm early warning monitoring method and system for remote mountainous areas. Background technique [0002] Mountain torrent disasters refer to the flood disasters caused by rainfall in hilly areas, and the disasters that cause losses to the national economy and people's lives and properties, such as mudslides and landslides induced by mountain torrents. The current early warning system of rainstorm and flash flood disasters in my country generally uses rainfall and water level as early warning indicators. For rivers in remote mountainous areas, landslides and blockages often occur during the process of heavy rain and flash floods, and even the flow channels are re-opened. As an early warning indicator, it is prone to the phenomenon of missed warnings, and the early warning effect is poor. Therefore, a method and system for early warning and monitoring o...
