The infrared fill light 2 uses a fill light group at a specific angle to achieve uniform fill light, so that the camera device 3 can also be clearly monitored at night. The acoustic and visual alarm light 6 extends out of the shell 1. In this embodiment, the acoustic and visual alarm light 6 is set at the top. When the light flashes, it can clearly warn the detection personnel.

[0024] Among them, the laser distance measuring device 4 is used to measure the axial displacement value of the target. When the axial displacement value reaches the preset standard value, it will trigger the centralized control mainboard 5 to control the sound and light alarm light 6 to alarm the overturning. The camera device 3 is used to detect the vertical displacement value of the target. When the vertical displacement value reaches the preset standard value, it will trigger the centralized control mainboard 5 to control the sound and light alarm light 6 to alarm the settlement.

[0025] Preferably, combined Figure 3 , Figure 4 As shown, the housing 1 includes a front cover 11, a sleeve 12 and a rear cover 13. The front cover 11 and the rear cover 13 cover the sleeve 12. The front cover 11 is provided with a first through hole 111, a second through hole 112 and a third through hole 113 adapted to the infrared fill light 2, the camera device 3 and the laser distance measuring device 4, so that the infrared fill light 2 can pass through the front cover 11 for fill light, and the camera device 3 and the laser distance measuring device 4 can pass through the front cover 11 for monitoring.

[0027] Preferably, it also includes a sliding baffle 7 for shading. The sliding baffle 7 is set on the shell 1 and slides along the shell 1. In the period of strong light, the sliding baffle 7 is adjusted to block the light to prevent strong light from directly shining or reflecting on the lens and causing overexposure, resulting in unclear details and reducing the monitoring quality.

[0030] Of course, in actual application, other structures that can achieve sliding can also be used, and the above two structures do not limit the patent scope of the present utility model.

[0031] Preferably, the sliding baffle 7 is in the shape of a hat brim extending downward on both sides. To a certain extent, adjusting the sliding baffle 7 can also block strong light from both sides. However, since the sliding baffle 7 extends and converges downward on both sides, it will not completely block all light, so that the area around the lens maintains an optimal brightness required for shooting.

[0032] Preferably, a U-shaped notch 73 is provided on the sliding baffle 7, and the sound and light alarm light 6 extends out of the sliding baffle 7 through the U-shaped notch 73.

[0033] Preferably, combined Figure 5 As shown, the infrared fill light 2 includes a translucent sheet 21 and fill light beads 22 for the light of the infrared fill light 2 to penetrate. Each infrared fill light 2 includes two fill light beads 221 with a light-emitting angle of 65°, two fill light beads 222 with a light-emitting angle of 30°, and two fill light beads 223 with a light-emitting angle of 8°, which are alternately and evenly distributed. Every two fill light beads 22 with the same angle are arranged in relative positions. LED beads are used in the utility model. The selection of fill light beads 22 with different angles and the position of the fill light beads 22 are designed according to the field of view of the camera device 3 of the utility model. Accordingly, uniform fill light within 1-100 meters can be achieved to ensure the detection quality under weak light conditions.

[0034] Preferably, a heat dissipation strip 16 is provided on the outer side of the housing 1. In actual use, the utility model needs to maintain the running state for a long time, and the temperature of the internal centralized control mainboard 5 will rise. If the temperature is too high, the centralized control mainboard 5 may be burned. The heat dissipation strip 16 can effectively dissipate the heat generated during operation, thereby extending the service life of the utility model.

[0035] It can be seen that the utility model discloses a settlement monitoring system for underpass construction of existing railways, which accurately measures the displacement value of the target through a combination of a camera device and a laser distance measuring device, wherein the laser distance measuring device is used to measure the axial displacement value of the target, and the camera device is used to detect the vertical displacement value of the target, and the overturning and settlement of the construction process are monitored in all directions. In addition, the internal structure of the above-mentioned monitoring system is compact and encapsulated with a shell, and the volume is very small; when the overturning and settlement are monitored, the sound and light alarm light flashes and a safety reminder sound is issued; the infrared fill light adopts a combination of lamp beads with different light-emitting angles to achieve uniform fill light in the range of 1 to 100 meters, ensure the detection effect at night, and improve the monitoring quality.
