Method and system for monitoring and early warning of natural disasters

Abstract

The invention discloses a method and a system for monitoring and early warning of natural disasters. The method includes that an information acquisition device acquires natural condition data and video monitoring data of each monitoring point in real time, and the natural condition data and video monitoring files obtained according to the video monitoring data are sent to an information processing system through an information transmission device; the information processing system respectively compares all the natural condition data to corresponding default disaster threshold values so as to judge whether natural disasters will happen at all the monitoring points; when a target monitoring point will have natural disasters, the information processing system indicates an early warning system to issue early warning information in preset site scope according to a preset early warning mode, and the target monitoring point is the monitoring point whose natural condition data arrives the corresponding default disaster threshold values. When one monitoring point will have natural disasters, the method and the system can achieve multistage emergency linkage and automatic early warning of the natural disasters, reduce construction cost, and are low in maintenance cost.

Description

technical field [0001] The invention relates to communication technology, in particular to a natural disaster monitoring and early warning method and system. Background technique [0002] my country is a mountainous country, and various natural disasters such as mountain torrents and geology often occur, such as wind, snow, rain, mudslides, landslides, earthquakes, etc., which seriously threaten the life of mountain residents, traffic arteries and municipal construction in our country. Safety. For example, in the Three Gorges Reservoir area, there are more than 4,000 dangerous rocks that are prone to collapse disasters in Chongqing alone, with a total of more than 50,000 dangerous rock bodies, threatening the lives and property safety of more than 800,000 people. The prevention and control of various natural disasters such as mountain torrents and geological disasters has received more and more close attention from the government and people from all walks of life. The govern...

Problems solved by technology

[0004] Insufficient information sharing: At present, natural disaster monitoring and early warning systems have been established in various grass-roots counties, but the natural disaster monitoring and early warning systems are independent of each other, and monitoring data cannot be shared between different natural disaster monitoring and early warning systems, nor can they communicate with municipal and provincial levels. The natural disaster monitoring and early warning system shares monitoring data. When a major natural disaster occurs in a county, the province, city and other counties cannot know, which is not conducive to the three-level emergency linkage of the province, city and county;

[0005] Limited early warning methods: In the existing natural disaster monitoring and early warning system, when it is judged that a natural disaster has occurred based on the collected monitoring data, the management personnel use traditional methods, such as: beating gongs and drums, tweeters, etc., or using text messages, faxes, etc. and other communication methods to notify relevant departments and local residents, it is impossible to realize real automatic early warning;

[0006] High construction cost: Since each natural disaster monitoring and early warning system is independent of each other, there are problems of repeated construction, repeated purchase of the same device in the system, and waste of system resources. For example, the construction budget of a county is about 3 million yuan, but the Only one or two towns in the county have invested about 1.6 million yuan in building a natural disaster monitoring and early warning system, while the remaining towns in the county cannot build a natural disaster monitoring and early warning system due to funding problems, basically using traditional manual on-site The early warning method of checking data and going back to statistical analysis greatly prolongs the early warning time limit and does not play the role of the natural disaster monitoring and early warning system. Therefore, the lack of funds caused by the high construction cost has restricted the construction of the natural disaster monitoring and early warning system;

[0007] High maintenance cost: Since the natural disaster monitoring and early warning systems are independent of each other, more manpower and material resources are required to maintain separately. The annual maintenance cost of each natural disaster monitoring and early warning system has reached between 150,000 and 200,000 yuan. In the case of insufficient construction funds, such high maintenance costs have added to the cost of the counties, and have also limited the improvement and normal use of the natural disaster monitoring and early warning system

The natural disaster monitoring and early warning system built by each county is maintained by the supplier during the free maintenance period. However, general equipment manufacturers do not have corresponding maintenance agencies in the local area, so maintenance costs will undoubtedly increase. After the free maintenance period expires , that is, each county maintains itself, but currently the county level basically does not have such maintenance capabilities, which also brings hidden dangers to the operation and use of the natural disaster monitoring and early warning system
