Disaster monitoring and management system based on buildings in ethnic villages

Description

2. Also important: the wooden beams and frames, as well as the numerous doors and windows, facilitate the rapid spread of fire, which can ravage an entire building and endanger this historical heritage. Currently, traditional monitoring and disaster management systems are insufficient to protect these historic buildings in ethnic villages. For the Hakka village, exposed to worm mold, foundation settling, and wall aging, there is a lack of precise and continuous monitoring methods capable of detecting subtle changes in advance. The warning mechanisms are delayed, preventing the implementation of effective preventive measures, which would make these buildings vulnerable to disasters and susceptible to heavy losses. 10 Content of the invention To remedy the shortcomings of existing techniques, the present invention provides a disaster monitoring and management system based on the buildings of ethnic villages,presenting the advantages of a strong proactive prevention capacity and faster and more effective disaster alerts, solving the problem of traditional systems whose capacity to protect the historic buildings of ethnic villages is insufficient and whose alert mechanisms are delayed.
