Description

Technical Field

[0001] The invention relates to the technical field of landslide monitoring, and in particular to a landslide type monitoring device. Background Art

[0002] Scientific landslide classification helps guide survey work, measure and identify the possibility of landslides in a given area, predict the stability of slopes and formulate corresponding anti-slip measures. However, few scholars in China have conducted research and inventions on landslide type monitoring. In view of this technical gap, the present invention proposes a landslide type monitoring device with relatively sensitive monitoring.

[0003] There are many bases for landslide classification. Currently, most researchers mainly classify landslides into creeping landslides, slow landslides, medium-speed landslides and high-speed landslides based on the sliding speed, and classify landslides into push-down landslides, traction landslides, translational landslides and mixed landslides based on the sliding dynamics properties. In view of these two landslide classification standards, the present invention designs a landslide type monitoring device. Summary of the invention

[0004] The purpose of the present invention is to overcome the shortcomings of the prior art, meet practical needs, and provide a landslide type monitoring device.

[0005] In order to achieve the purpose of the present invention, the technical solution adopted by the present invention is as follows: the landslide type monitoring device comprises two probes 21 and a control box 2.

Each monitoring nail 8 is equipped with an inclinometer 7, a temperature and humidity sensing and processing device 9, a micro fan 10, a speed sensor 11 and a three-axis acceleration sensor 12.

The monitoring center determines the type of the landslide at the location through data analysis.

[0006] The device for monitoring the type of landslide is characterized in that: the device monitors the sliding speed of the landslide through a speed sensor 11, monitors the mechanical characteristics caused by the starting position of the landslide through a three-axis acceleration sensor 12, and obtains the overall picture of the landslide through an image sensor 14, and compares it with historical landslides to finally determine the type of landslide.

[0025] The present invention discloses a landslide type monitoring device, comprising two probes 21 and a control box 2. The probe 21 comprises fixing nails 19 on both sides, a plurality of monitoring nails 8 in the middle and an upper connecting plate 20, each monitoring nail 8 is equipped with an inclinometer 7, a temperature and humidity sensing and processing device 9, a micro fan 10, a speed sensor 11 and a three-axis acceleration sensor 12. The control box 2 is internally equipped with a fiber grating demodulator 5, a GPS positioning device 17, a temperature and humidity sensing and processing device 3, a micro fan 4 and a battery 18, and a wireless signal transmitting device 16, a solar panel 1 connected by a support rod 15 and an image sensor 14 are fixed on the upper part. The speed sensor 11, the three-axis acceleration sensor 12 and the image sensor 14 are connected to the fiber grating demodulator 5 through a data line 6, so that the monitored landslide information is transmitted to the fiber grating demodulator 5, and then the relevant information is transmitted to the monitoring center through the wireless signal transmitting device 16, and the monitoring center determines the type of the landslide at the location through data analysis.

[0026] The device monitors the sliding speed of the landslide through the speed sensor 11, monitors the mechanical characteristics caused by the starting position of the landslide through the three-axis acceleration sensor 12, and obtains the overall picture of the landslide through the image sensor 14, and compares it with the historical landslides to finally determine the landslide type.

[0027] The probe 21 is in a comb shape, including fixing nails 19 on both sides, a plurality of monitoring nails 8 in the middle and an upper connecting plate 20. The fixing nails 19, the middle monitoring nails 8 and the connecting plate 20 are detachably connected.

[0028] The fixing nails 19 are equilateral angle steels, the monitoring nails 8 are made of stainless steel, and the connecting plate 20 is an I-beam.

[0029] The two probes 21 are respectively placed on the upper edge and the lower edge of the landslide surface 13 to monitor the landslide conditions at the upper and lower edges respectively.

[0030] The inclinometer 7 is used to ensure that the installation directions of the probes at the upper and lower edges are consistent; the three-axis acceleration sensor 12 is placed at the lower part of the monitoring nail 8 to monitor the acceleration of the soil in the direction of the landslide and the direction perpendicular to this direction; the speed sensor 11 is placed on the side of the monitoring nail 8 to monitor the speed of the landslide; the temperature and humidity sensing and processing device 9 is connected to the micro fan 10 to adjust the internal environment of the monitoring nail 8.

[0034] When the sliding speed is used as the standard, the type of landslide (creeping landslide, slow landslide, medium-speed landslide and high-speed landslide) is determined according to the monitored landslide sliding speed. When the mechanical properties of the landslide are used as the standard, the landslide acceleration in two directions obtained by monitoring is used to preliminarily determine the type of landslide (push-down landslide, traction landslide, translational landslide and mixed landslide). The landslide type is then confirmed by comparing the image optical information with historical landslides. Finally, the final landslide type is obtained by combining the above two standards.
