Mountain disaster monitoring, forecasting and early warning system

Abstract

The invention discloses a mountain disaster monitoring, forecasting and early warning system which is characterized by comprising a data acquisition system, a data transmission system, a data processing center and an early warning system. The data acquisition system is used for collecting relevant data information and transmitting the relevant data information to the data processing center through the data transmission system. The data processing center analyzes and processes the transmitted data and stores the data. The early warning system judges whether to carry out an early warning operation or not according to the processing result of the data processing center. The system belongs to early warning and an early warning method based on a disaster forming mechanism and a disaster forming process, the precision is high, the false alarm rate is low, the construction cost of the whole set of system is low, the system is easy to realize and is promoted to hydropower, transportation, and city monitoring and early warning practices through experiments, and significant disaster reduction benefit and social and economic benefit are obtained.

Description

technical field [0001] The invention relates to the field of mountain disaster monitoring, prediction and early warning, in particular to a mountain disaster monitoring, prediction and early warning system. Background technique [0002] Debris flow is a geological disaster with many points and wide areas. It has occurred frequently in recent years. For example, a large number of debris flow disasters in Zhouqu Sanyanyu Valley and Qingping Wenjiagou in China in 2010 caused more than 2,900 deaths and missing in China; in 2014, the landslide in Washington State, USA transformed 45 people were killed or missing due to the mudslide disaster. The large-scale mudslide disaster shows that the task of disaster prevention is still very arduous. Due to the high investment and long period of engineering disaster prevention measures, only part of the disaster prevention and mitigation problems can be solved in the short term; for disastrous debris flow, monitoring and early warning has t...

AI Technical Summary

Problems solved by technology

[0004] (1) There is no effective identification method for potential debris flow landslides, and it is impossible to effectively predict and monitor them;

[0005] (2) There is a lack of early warning and forecast methods based on disaster formation mechanisms, mainly relying on traditional statistical methods and a single critical precipitation index, and there are still problems of low accuracy in practical applications;

[0006] (3) The monitoring equipment has the problems of high price, poor economical practicability, poor stability and low reliability
