[0002] The long history of Hakka settlement buildings is facing many disaster threats. When a mountain flood occurs, the water in the mountain area is turbulent, and it carries mud and stones. Once the surrounding embankment and road are washed away, the soil building foundation is easy to be soaked, the wall is severely impacted, and then the collapse phenomenon may occur. During the plum rain season, heavy rain may cause waterlogging. If the soil building drainage system is not cleaned and dredged in time, the accumulated rainwater will soak the indoor goods, affecting the safety of residence. When an earthquake occurs, although the soil building structure is stable, under strong vibration, the wall may crack and the tiles may fall off, threatening the lives of people inside the building.

BRIEF DESCRIPTION OF DRAWINGS

[0017] Figure 1 The system flowchart of the present application. DETAILED DESCRIPTION

[0018] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described, obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work belong to the protection scope of the present application.

[0019] Embodiment 1 Please refer to Figure 1 The present application provides a disaster prevention and control monitoring system based on ethnic settlement buildings, comprising a multi-dimensional monitoring module and an intelligent monitoring module. The multi-dimensional monitoring module is composed of a building structure unit, an environment monitoring unit and an activity monitoring unit. The building structure unit collects a structure data set through network connection of a database, an infrared thermal imager, an ultrasonic detector, a crack width detector and a laser scanner. The structure data set includes the structure monitoring data of the tulou. The structure data set includes the column volume, the internal termite volume of the column, the column diameter, the column bending strength, the column crack number, the column construction time, the maximum column crack width, the column inclination angle, the tulou elevation, the tulou original center, the outer wall monitoring result, the courtyard area and the ring corridor width. Specifically, in a humid indoor environment, wood columns are more likely to absorb and retain water, providing favorable conditions for the survival and reproduction of termites. Termite damage can cause wood columns to have lower density and loose structure. These damaged areas will show obvious temperature anomalies in infrared thermal imaging. The infrared thermal imager can directly reflect the location and range of termite damage by capturing this abnormal temperature difference. Over time, the longer the construction time of the tulou, the more the internal fiber organization of the column will be damaged, decomposed and peeled off, resulting in a uniform reduction in diameter. In addition, the propagation speed of ultrasonic waves in wood is positively correlated with the density of wood. When the bending strength of wood is higher, the internal structure of the column is more dense, and the propagation speed of ultrasonic waves is faster. The larger the inclination angle of the column, the weaker its bearing strength. The environment monitoring unit collects an environment data set through network connection of a big data platform, a smoke detector and a liquid level meter. The environment data set includes the environment monitoring data of the tulou. The environment data set includes air temperature, humidity, daily rainfall, peak ground acceleration, seismic wave frequency, smoke concentration and fire water demand. The activity monitoring unit collects an activity data set through network connection of a monitoring device. The activity data set includes the activity monitoring data inside the tulou.

Specifically, the corruption threshold , the deformation threshold , the environment threshold and the evacuation threshold are derived from historical experience and actual cases. Through long-term observation and research on a large number of tulou, a wealth of historical data related to column corruption, wall deformation, natural disasters and emergency evacuation drills has been accumulated. When some tulou in the past showed signs of obvious column decay, cracking, and reduced wall strength, etc., the corresponding corruption degree index, deformation degree index, environmental disaster index and evacuation efficiency index were determined through detection and analysis. When the corruption index exceeds the corruption threshold , it indicates that the degree of column corruption inside the tulou has exceeded the safety threshold, and a column early warning signal is generated, and the column should be reinforced in time. When the deformation index exceeds the deformation threshold , it indicates that the degree of wall deformation inside the tulou has exceeded the safety threshold, and a wall early warning signal is generated, and the wall should be reinforced in time. When the environment score is lower than the environment threshold , it indicates that the disaster hidden danger of the environment where the tulou is located is significant, and a high-risk early warning signal is generated, and the disaster hidden danger should be removed in time and personnel should be evacuated, and the evacuation index is lower than the evacuation threshold , indicating that the emergency evacuation capability of the tulou is insufficient, and a high-risk early warning signal is generated, and the entrance should be closed in time and personnel should be evacuated.

[0026]

[0027] Table 1. Experimental data on the corrosion index Specifically, adjacent pillars A, B, and C inside the Tulou were selected as experimental subjects. In the table, the standard values ​​used to measure the degree of decay of the three pillars are the same. , , , , , , ; Corruption threshold The corrosion index was set to 0.6. Based on the results, the corrosion indices of columns A and B were determined. It has exceeded the corruption threshold. This indicates that the corrosion of pillars A and B inside the Tulou is severe, generating a warning signal for the pillars, and pillars A and B should be reinforced in a timely manner.

[0028] In this embodiment, since the number of layers of the tulou is mainly 3 to 5 layers, the bottom layer includes a courtyard, an ancestral hall, a school and a kitchen, the second layer is mostly a granary and a storage room, and the third layer and above are mostly living rooms. When the space is divided by the column, the diameter of the column arranged on each layer of space is different. Therefore, when the damage degree of the tulou is accurately quantified, the standard value and weight of the column of different layers in measuring the degradation degree are also different. The diameter of the column in the bottom layer is larger, and hard wood is mostly used, which is the basis of the vertical load-bearing system of the tulou. When the degradation degree of the column in the bottom layer is quantified, more attention is paid to the pre-bending strength and the inclination angle. The diameter of the column in the middle layer is smaller, and part of it adopts the combination of bamboo and wood, which can not only reduce the self-weight, but also ensure the toughness. When the degradation degree of the column in the middle layer is quantified, the focus is on the problem of insect boring and decay. The column in the upper layer is offset to the center point of the tulou, so as to shorten the force arm and enhance the lateral displacement resistance. Usually, tung oil or lime water is used for corrosion prevention. When the degradation degree of the column in the upper layer is quantified, the main attention is paid to the problem of decay and cracks.
