Embodiment 1

[0032] figure 1 and figure 2 are a cross-sectional schematic diagram and a cross-sectional schematic diagram of the chemiluminescence sensor 1, respectively. The chemiluminescent sensor 1 structurally includes a photosensitive resistor 11, a first hollow tube 12, a hollow shear rod 13, a second hollow tube 14, and a cylindrical baffle 15. The photosensitive resistor 11 is connected to the wireless data acquisition and transmission module 2 The signal is connected, the inner cavity of the first hollow tube 12 is divided into two closed chambers by the second hollow tube 14 sheathed inside it, and the two chambers are filled with chemical substance A and chemical substance B respectively. Chemical substance A and chemical substance B can react to generate peroxyacid, photoresistor 11 is evenly arranged in the upper, middle and lower positions of the inner cavity of the first hollow tube 12, fluorescent dye and photoresistor 11 are respectively arranged in two chambers or co-l...

Embodiment 2

[0040] Below in conjunction with accompanying drawing, the action process of landslide multi-level monitoring and early warning device of the present invention is described:

[0041] The landslide multi-level monitoring and early warning device is installed when the slope is in the monitoring and early warning state, and the chemical substance A and the chemical substance B are in an isolated state in the chemiluminescence sensor 1 . When a landslide occurs, the external force impacts the chemiluminescent sensor 1, and the cylindrical baffle 15 increases the area of ​​action of the external force on the chemiluminescent sensor, and the second hollow tube 14 made of glass breaks, so that chemical substance B and chemical substance A are mixed , produces a chemical reaction to generate two molecules of phenol and one molecule of peroxyester (1,2-dioxetanone), and the peroxyacid will spontaneously decompose into carbon dioxide, releasing energy that can excite the fluorescent dye,...

[0043] Attached below image 3 Describe the application method of this device:

[0044] (1) Select the slope to be monitored, and find out the most likely landslide location, insert the chemiluminescence sensor 1 into the slope, and the insertion depth is greater than the slope generated by the landslide, each slope according to specific requirements No less than three chemiluminescence sensors 1 can be set, and at least one chemiluminescence sensor (1) of three stiffness levels is set for each, and multiple chemiluminescence sensors 1 are set in series or in parallel;

[0045] (2) Connect the wireless data acquisition and transmission module 2 of each chemiluminescent sensor 1 to the solar battery 3, and start the solar battery 3;

[0046] (3) When the signal amplitude collected by the wireless data acquisition and transmission module 2 corresponding to all the chemiluminescent sensors 1 remains unchanged, it means that the soil is stable, and the soil slope does not slide o...

Abstract

The invention discloses a landslide multi-stage monitoring and early warning device and an application method thereof, belonging to the technical field of geological disaster monitoring. The multi-level monitoring and early warning device includes a chemiluminescent sensor, a wireless data acquisition and transmission module, and a solar battery. Chemical substances A and B are respectively set in two independent chambers of the chemiluminescent sensor, and are mixed under the action of an external force to generate peroxyacid. The energy that excites the fluorescent dye causes the resistance value of the photoresistor to change, so that the signal is transmitted to the wireless data acquisition and transmission module, and an early warning signal is issued. By setting multiple chemiluminescent sensors with different stiffness levels on the slope, different levels of landslide warning can be realized. The device has the characteristics of convenient installation, sensitive response, high accuracy, real-time monitoring, low energy consumption, and strong environmental adaptability. casualties.

Description

technical field [0001] The invention relates to the technical field of geological disaster monitoring, in particular to a landslide multi-stage monitoring and early warning device and an application method of the device. Background technique [0002] Landslide refers to the soil or rock mass on the slope, affected by factors such as river scouring, groundwater activity, rainwater immersion, earthquake and artificial slope cutting, under the action of gravity, along a certain weak surface or weak zone, the whole or scattered The natural phenomenon of land sliding downhill. Many of the world's most landslide-prone regions are also the least developed. Large-scale deforestation, population growth, and poor engineering design along mountain slopes create high-risk areas for landslides, especially during heavy rainfall and in areas near earthquake epicenters. [0003] The triggers and causes of landslides are diverse and landslide monitoring requires a multidisciplinary approac...
