Description

Technical Field

[0001] The utility model relates to the technical field of settlement observation, in particular to a settlement observation system. Background Art

[0002] Subsidence observation refers to the monitoring of buildings, land or infrastructure to detect their settlement. Subsidence refers to the phenomenon of sinking or collapse due to factors such as compression of underground soil layers or the weight of the building itself. This observation is usually to monitor the stability of buildings or land and possible structural problems or geological risks.

[0003] Taking the observation of building settlement as an example, surveyors usually measure the height of a certain observation point of the building within a certain period using a total station or a level.

[0004] If you want to analyze the settlement trend of a building, you will need a lot of data, so staff will need to take repeated measurements, which will require a lot of labor costs. Utility Model Content

For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0032] The present disclosure will be described in detail below with reference to the accompanying drawings and in conjunction with embodiments.

[0033] First see Figure 1 , Figure 1 FIG. 1 is a schematic diagram of a structure of an embodiment of a settlement observation system of the utility model. Figure 1 As shown, the settlement observation system includes a laser emitting assembly 3 and a plurality of settlement observation boxes 4. The laser emitting assembly 3 is set on a fixed point 1. The plurality of settlement observation boxes 4 are set at observation points 2 such as buildings. The laser emitting assembly 3 emits laser to each settlement observation box 4 to detect the settlement information at the location of each settlement observation box 4, so as to realize the function of automatically observing settlement.

[0034] See next Figure 2 , Figure 2 FIG. 1 is a schematic diagram of the structure of an embodiment of the laser emission assembly of the utility model. Figure 2 As shown, the laser emitting assembly 3 includes a bracket 31, a rotating part 32 arranged on the bracket 31, and a laser emitter 33 connected to the rotating part 32. The bracket 31 plays a supporting role and can raise the laser emitter 33 to a preset height. The rotating part 32 is used to drive the laser emitter 33 to rotate so that the laser emitter 33 can face each settlement observation box 4. As an example, the rotating part 32 can be a hollow rotating motor.

[0035] Furthermore, a rangefinder 34 may be provided at the bottom of the laser emitter 33. The rangefinder 34 is used to detect the height of the laser emitter 33 from the ground and determine whether the height from the ground deviates from the preset height. As an example, the rangefinder 34 includes but is not limited to one of the following: an infrared rangefinder, an ultrasonic rangefinder, and a radar rangefinder.

[0036] A telescopic part 35 may be provided between the rotating part 32 and the laser emitter 33, and the telescopic part 35 is used to drive the laser emitter 33 to move up and down. When the height above the ground detected by the rangefinder 34 deviates from the preset height, the height above the ground of the laser emitter 33 may be adjusted by the telescopic part 35. As an example, the telescopic part 35 may be an electric push rod, an electromagnetic push rod, etc.

[0037] See next Figure 3 and Figure 4 , Figure 3 This is a structural schematic diagram of an embodiment of a settlement observation box of the utility model; Figure 4 FIG. 1 is a schematic diagram of the installation of the laser receiver of the utility model. Figure 3As shown, the settlement observation box 4 includes a box body 41 having a vertical opening 42 and a plurality of laser receivers 43 arranged in the box body 41. The plurality of laser receivers 43 are arranged in the vertical direction. Each laser receiver 43 is evenly spaced. Those skilled in the art can adjust the above intervals according to actual conditions.

[0038] The laser emitted by the laser emitter 33 can pass through the vertical opening 42 and irradiate a laser receiver 43. Each laser receiver 43 corresponds to a different height value, and the corresponding settlement height can be determined by receiving the electrical signal of the laser receiver 43.

[0039] Re-read Figure 1 In order to prevent the vertical opening 42 from blocking the laser, each settlement observation box 4 can be arranged toward the laser emitter 33, that is, the vertical opening 42 is toward the axial direction of the rotating part 32.

[0040] The plurality of laser receivers 43 may be connected to the mounting plate 44. The plurality of laser receivers 43 are arranged gradually toward the laser receiver 43 from bottom to top. This staggered arrangement can prevent the laser from irradiating two adjacent laser receivers 43, thereby reducing the measurement error.

[0041] The laser receiver 43 may be a photodiode.

[0042] The settlement observation system may further include a controller, which is in communication with the rotating part 32, the laser transmitter 33, the laser receiver 43, the rangefinder 34, and the telescopic part. As an example, the controller may be a PLC (Programmable Logic Controller).

[0043] In actual settlement observation, the controller controls the rotating part 32 to rotate to a preset angle so that the laser emitter 33 faces a settlement observation box 4. The controller controls the laser emitter 33 to turn on. After the laser irradiates a laser receiver 43, the laser receiver 43 converts the optical signal into an electrical signal and transmits it to the controller. The controller can determine the settlement value of the observation point 2 where the settlement observation box 4 is located based on the height value corresponding to the laser receiver 43. Next, the controller controls the rotating part 32 to rotate toward the next settlement observation box 4. It should be noted that due to the limitation of the size of the photodiode, the measurement accuracy of this system is not as good as that of a total station or a level, but the collected data can provide data support for analyzing the settlement trend of the building.

[0044] The controller can collect the height above the ground detected by the rangefinder 34, and compare the height above the ground with the preset height. If the height above the ground does not match the preset height, the telescopic part is controlled to be adjusted to avoid errors in settlement observation caused by deviations in the height of the laser emitter 33, thereby improving the reliability of the system.

[0045] Furthermore, the controller may include a memory for storing the settlement information of each settlement observation box 4, thereby not only realizing automated settlement observation, but also providing data support for analyzing the settlement of the building, thereby reducing labor costs.

[0046] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it. Although the utility model has been described in detail with reference to the aforementioned embodiments, ordinary technicians in this field should understand that they can still modify the technical solutions recorded in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not make the essence of the corresponding technical solution deviate from the scope of the technical solution of the embodiments of the utility model.
