Description

Technical Field

[0001] The utility model relates to the field of geological disaster monitoring, and more specifically to a slope debris flow source monitoring system based on fluorescent marking. Background Art

[0002] Debris flow is a common natural geological disaster. Because of its sudden occurrence and great destructive power, it poses a serious threat to people's lives and property.

[0003] Debris flow source is one of the three elements for its formation and development. Debris flow source identification is the basis for scientifically assessing the scale and degree of damage of debris flow, and is also the key basis for debris flow prevention and control engineering measures. In order to effectively prevent and respond to debris flow disasters, it is necessary to effectively identify and monitor debris flow sources. Long linear projects such as highways involve a very wide range. The use of conventional survey methods for geological disaster surveys such as debris flows often has problems such as low efficiency, low accuracy, poor real-time performance, and high personal safety risks for investigators, which makes it difficult to meet the needs of geological disaster prevention and control. Utility Model Content

[0004] The utility model aims to overcome at least one defect (shortcoming) of the above-mentioned prior art, and provides a slope debris flow source monitoring system based on fluorescent marking to improve the monitoring accuracy of the debris flow source.

[0005] The utility model provides a slope debris flow source monitoring system based on fluorescence marking, including fluorescent marker source particles, a fluorescence excitation device, a fluorescence detection device, a data analysis system, a terminal service system and a bearing device.

[0006] The fluorescent marker source particles are distributed on the slope; the fluorescent excitation device is arranged on the slope, and is used to emit laser to excite the fluorescence of the fluorescent marker source particles; the fluorescent detection device is used to receive and analyze the fluorescent signal of the fluorescent marker source particles to form a fluorescent spectrum; the data analysis system is used to analyze the fluorescent spectrum, obtain the characteristic information and behavior information of the fluorescent marker source particles, construct the movement trajectory information of the fluorescent marker source particles, and transmit the movement trajectory information to the terminal service system;

[0007] The fluorescence detection device and the data analysis system are both arranged on the carrying device, and the carrying device positions the fluorescence detection device and the data analysis system above the slope. In the present technical scheme, the fluorescent marker source particles are the monitoring target, that is, the source particles with fluorescent markers. The fluorescence excitation device can emit lasers, which usually have high energy and monochromaticity and can excite fluorescent substances; the fluorescence detection device can monitor the fluorescence in real time, and the fluorescent marker source particles are scanned and monitored by the practical fluorescence detection device, and the fluorescence signals are received and recorded, especially the fluorescence signal data before and after rainfall. The characteristic information refers to the particle size or type of the fluorescent marker source particles. The behavior information refers to the movement information such as the movement time and movement position of the fluorescent marker source particles. The data analysis system identifies the characteristic information of the source particles according to the fluorescent markers of the source particles, obtains the movement time and movement position of the specific source particles according to the fluorescence receiving time and receiving angle of the fluorescent marker source particles, and constructs the movement trajectory map of the source particles in combination with the characteristic information and behavior information, and transmits it to the terminal service system, such as the background server, and then obtains the distribution and migration law of the fluorescent marker source particles, so as to realize real-time monitoring thereof.

[0008] Fluorescence moves with the movement of source particles, and its movement is sensitive and easy to detect. The data analysis system can accurately monitor the changes of source particles by identifying fluorescence, thereby improving the accuracy of its monitoring. In addition, by using the fluorescence detection device to monitor the fluorescent-labeled source particles in real time, this solution can grasp the information of source particles in real time, thereby helping staff to discover problems in time, which is conducive to the prevention of mudslide disasters. At the same time, when monitoring, staff only need to obtain the movement information of source particles from the terminal service system, reducing the risk of staff investigation.

[0009] Furthermore, the fluorescent marker source particles include debris flow source particles, and the surfaces of the debris flow source particles are provided with a numbering coating, a first transparent film layer, a fluorescent layer, a second transparent film layer and a protective coating in sequence from the inside to the outside.

[0010] Preferably, the first transparent film layer is sandwiched between the number coating layer and the fluorescent layer to prevent the fluorescent layer from penetrating into the number coating layer. The second transparent film layer is sandwiched between the protective coating layer and the fluorescent layer to form line grooves of different shapes, such as dots, strips, and grids, and the fluorescent layer also forms a corresponding shape.

[0011] Furthermore, the fluorescent layer is provided on the first transparent film layer by dipping, coating, spraying or adhesive.

[0012] Furthermore, the numbered coating is an acrylic layer, the first transparent film layer and the second transparent film layer are both polyurethane film layers or polyethylene film layers, the fluorescent layer is a silicate phosphor layer or a perovskite phosphor layer, and the protective coating is an epoxy resin coating, a varnish coating or a silicone rubber coating.

[0013] In the present technical solution, silicate phosphor or perovskite phosphor is used as the material of the fluorescent layer, which has the advantages of being environmentally friendly and pollution-free, having strong coloring, not easy to fade, and being resistant to water and high and low temperatures.

[0014] Furthermore, it also includes a carrying device, the fluorescence detection device is installed on the carrying device, and the carrying device positions the fluorescence detection device in the air.

[0015] Furthermore, the carrying device is a drone.

[0016] In this technical solution, the fluorescence detection device is installed on the drone, which can realize the tracking of fluorescent marker source particles, and the tracking position is flexible and variable.

[0017] Furthermore, the fluorescent layer is composed of a plurality of fluorescent modules, and the fluorescent modules are in the form of dots, stripes or meshes. The dot-shaped and strip-shaped fluorescent modules are distributed at intervals, and the mesh-shaped fluorescent modules wrap the source particles in a one-piece manner. Different fluorescent modules form different fluorescent markers, and different fluorescent markers represent different information of the source particles, such as particle size, type, etc. This makes it convenient to obtain source information.

[0018] Furthermore, the thickness of the fluorescent layer is 2-4 mm.

[0019] Furthermore, the particle size of the debris flow source particles is greater than 5 mm.

[0020] Preferably, the particle size range of the debris flow source particles is 5 to 400 mm.

[0021] Furthermore, the fluorescence excitation device is an ultraviolet emitting mechanism or a blue laser emitting mechanism, and the fluorescence detection device is a fluorescence spectrometer.

[0022] Compared with the prior art, the beneficial effects of the utility model are:

[0023] (1) Fluorescence moves with the movement of source particles, and its movement is sensitive and easy to detect. The data analysis system can accurately monitor the changes of source particles by identifying fluorescence, thereby improving the accuracy of its monitoring;

[0024] (2) Through the real-time monitoring of fluorescent-labeled source particles by the fluorescence detection device, this solution can obtain the information of source particles in real time, thereby helping the staff to find problems in time, which is conducive to the prevention of debris flow disasters;

[0025] (3) During monitoring, staff only need to obtain the movement information of source particles from the terminal service system, which reduces the risk of staff monitoring. BRIEF DESCRIPTION OF THE DRAWINGS

When the fluorescent modules 310 are in the form of dots or stripes, they are distributed at intervals.
