[0034] The laser displacement meter can realize high-precision displacement measurement in an environment blocked by high dust and high coal piles through the combination of different wavelengths, powers and coupling efficiencies, short-wavelength laser can provide higher resolution, long-wavelength laser has better penetrability and reflectivity, and the power suitable for the current environment is selected to ensure sufficient reflection signal strength and reduce environmental noise interference. Figure 2 is a laser displacement module installation schematic diagram according to the embodiment of the application, as shown in the figure, Figure 2 the laser displacement meter 110 cooperates with the corresponding laser reflection plate 111 to measure the distance between two points to obtain displacement data.
[0035] In the embodiment of the application, the laser emission group has a plurality of implementation manners.
[0036] In one embodiment, the laser emission group comprises a first laser emitter and a second laser emitter independently enabled, and the first laser emitter and the second laser emitter emit laser beams with different wavelengths.
[0037] It should be noted that the number of the first laser emitter and the second laser emitter in the same laser emission group is not limited, and optionally, the laser emission group can further comprise a third laser emitter for emitting a laser beam different from the wavelengths of the first laser emitter and the second laser emitter, that is, the laser emission group comprises a plurality of laser emitters for emitting laser beams with different wavelengths.
[0038] Similarly, the laser emission group can further comprise a plurality of laser emitters for emitting laser beams with different powers.
[0039] In another embodiment, the laser emission group comprises a laser emitter and a wavelength conversion component 。
[0040] The laser emitter is configured to emit a laser beam.
[0041] The wavelength conversion component is located in front of the laser emitter along the direction of the laser beam emission, configured to receive the laser beam and convert the wavelength of the laser beam.
[0042] In this embodiment, the wavelength of the laser beam emitted by the laser emitter is changed by the wavelength conversion component, so as to achieve the purpose of emitting laser beams of different wavelengths.
[0043] Optionally, the laser emission group further comprises a power conversion component, which changes the power of the laser beam emitted by the laser emitter, so as to achieve the purpose of emitting laser beams of different powers.
[0044] In some embodiments, the space truss structure comprises two edge regions at both ends of the extension direction, and a middle region between the two edge regions.
[0045] The laser displacement module is arranged on the structural nodes in the edge regions and the middle region.
[0046] Figure 3 is a schematic diagram of the arrangement area of a laser displacement module according to an embodiment of the present application, as Figure 3 The arrangement area of the laser displacement module comprises a first edge region 21 on the left side of the extension direction of the space truss structure and a second edge region 25 on the right side, and a middle region 23 between the two edge regions. The middle part is the part where the force is concentrated, especially the roof, which usually needs to be monitored, and the deformation of the roof often affects the stability of the whole structure, so monitoring points should be set on the middle part and the edge of the roof.
[0047] In some embodiments, the space truss structure further comprises a target region between the two edge regions and the middle region.
[0048] The laser displacement module is further arranged on the structural nodes in the target region.
[0049] Continuing to refer to Figure 3 To improve the reliability of monitoring, a first target region 22 can be arranged between the first edge region 21 and the middle region 23, and a second target region 24 can be arranged between the second edge region 22 and the middle region 23.

The support column is an important part of bearing load, and the deformation may affect the stability and safety of the whole structure; the connection of the parts is also an area where deformation is prone to occur, especially the bottom and top connection of the wall, which is easy to deform slightly due to external load or long-term use.
[0051] The data processing terminal 12 is in communication connection with the laser displacement module, used for receiving the displacement data collected by the laser displacement module, so as to perform deformation monitoring according to the displacement data.
[0052] The embodiment adopts wireless transmission technology to transmit the data collected by the laser displacement module to the data processing unit, avoiding data transmission interruption or delay caused by bad environment.

[0054] In some embodiments, the system further comprises a displacement warning component for issuing a horizontal displacement warning signal.
[0055] In some embodiments, the system further comprises a deformation warning component for issuing a deformation warning signal.
[0056] When the monitored structural deformation or foundation horizontal displacement exceeds the preset safety threshold, the warning component will issue a warning to remind the staff to take timely measures.
[0057] Through the above system, a plurality of laser displacement modules 11 are arranged on the structural nodes in the net rack shed structure for collecting displacement data of the net rack shed structure. The laser displacement module 11 includes a laser displacement meter and a laser reflector plate matched with the laser displacement meter. The laser displacement meter is internally provided with a laser emission group, and the laser emission group is used for emitting laser beams with different wavelengths and powers. The data processing terminal 12 is in communication connection with the laser displacement module, used for receiving the displacement data collected by the laser displacement module, so as to perform deformation monitoring according to the displacement data, solving the problem of low accuracy of the net rack shed structure deformation detection method. A plurality of laser displacement modules are arranged to measure the deformation of different positions of the net rack shed structure, so as to improve the monitoring accuracy. In addition, short-wavelength laser can provide higher resolution, long-wavelength laser has better penetration and reflectivity, and the power is selected to adapt to the current environment to ensure sufficient reflection signal strength and reduce environmental noise interference. Therefore, by emitting laser beams with different wavelengths and powers through the laser emission group, high-precision displacement measurement can be realized in the environment blocked by high dust and high coal piles.
[0058] The combination of the laser displacement meter and the wireless transmission technology enables the system to operate stably in a high-interference environment, and the system can monitor the deformation of the net rack shed structure and the displacement of the foundation in real time and discover potential safety hazards in time.
[0059] By combining the research and test of different wavelengths, powers and coupling efficiencies of the laser displacement meter, a high-interference and high-precision structural deformation measurement system is designed, and the size of the relative displacement of the foundation and the structural deformation variable are indirectly calculated by combining the existing structural spatial displacement model.
[0060] In some embodiments, the system further comprises a power management unit, and the power management unit is electrically connected with the laser displacement module and the data processing terminal respectively.
[0061] The power management unit comprises a power supply module, and the power supply module is used for providing power supply for the laser displacement module and the data processing terminal.
[0062] The power supply module provides stable power supply for the entire system.
[0063] In some embodiments, the power management unit further comprises a backup power supply module.
