[0024] Figure 3 The utility model discloses a circuit connection block diagram. Specific implementation

[0025] The utility model is further explained in connection with the drawings and specific implementation.

[0026] Reference Figure 1 、 Figure 2 And Figure 3 The embodiment provides a kind of steel structure shaft settlement monitoring device, comprising: the three above interval setting settlement observation reference point (not marked in drawing) of foundation 200 on the bottom of the steel structure shaft 100 is directly arranged, each the settlement observation reference point is located on the same horizontal plane, and each settlement observation reference point cannot all be on the same straight line.The steel structure shaft 100 is existing structure, and the utility model does not involve the improvement to the steel structure shaft 100 itself structure, not detailed here.

[0027] One optical ranging sensor 2 is installed on each of the settlement observation reference point, and in the specific embodiment, the number of the optical ranging sensor 2 is set to three.In the specific embodiment, the optical ranging sensor 2 preferably uses laser ranging sensor, and those skilled in the art should understand the use method of laser ranging sensor, which is not described in detail here.

[0028] Reflective flat plate 1 is arranged at the bottom of the steel structure shaft 100 and along the vertical structure center line of the steel structure shaft 100.Those skilled in the art should understand that the steel structure shaft 100 structure center line position (such as Figure 1 Dotted line position in the middle).The surface of the reflective flat plate 1 is smooth, facilitating the reflection of light beam, and preferably, the surface of the reflective flat plate 1 can also be silver-plated.

[0029] Each of the optical ranging sensor 2 is not connected with the reflective flat plate 1, and the light beam emitted by each of the optical ranging sensor 2 is perpendicular to the horizontal plane and irradiates on the reflective flat plate 1;It should be noted that the light emitted by the optical ranging sensor 2 does not need to be perpendicular to the reflective flat plate 1, and only the optical ranging sensor 2 can receive the light beam reflected by the reflective flat plate 1.

[0030] It also includes: controller 3, prompt light 4, buzzer 5, display screen 6 and wireless communication module 7.The controller 3, prompt light 4, buzzer 5 and display screen 6 can be installed inside or outside the steel structure shaft 100.The wireless communication module 7 needs to be installed outside the steel structure shaft 100, and the wireless communication module 7 should be ensured not to be covered by other objects that can block signals.

[0031] The above-mentioned electronic components are all existing electronic devices, and those skilled in the art should have the ability to select the above-mentioned electronic devices. Preferably, in the present embodiment, the controller 3 adopts a Siemens S7-200 programmable controller; and the wireless communication module 7 adopts a 5G communication module.

[0032] The optical distance measuring sensor 2, the prompt light 4, the buzzer 5, and the display screen 6 are respectively electrically connected with the controller 3, and the wireless communication module 7 is in communication connection with the controller 3.

[0033] In the present embodiment, three optical distance measuring sensors 2 are arranged on the settlement observation reference points on the foundation 200, and three spatial coordinates are constructed according to the distances from the optical distance measuring sensors 2 to the reflecting plate 1 (with any one of the optical distance measuring sensors 2 as the origin). By observing the changes of the three spatial coordinates periodically and continuously, the average value of the changes of the three spatial coordinates can be obtained and displayed on the display screen 6, so that the settlement of the corresponding settlement observation reference points on the steel structure shaft 100 can be known. Of course, the more the settlement observation reference points are arranged, the more accurate the monitoring of the settlement of the steel structure shaft 100 is.

[0034] A spatial planar graph of the reflecting plate 1 can also be constructed according to the three spatial coordinates. The planar inclination angle, i.e. the inclination angle of the steel structure shaft, can be calculated according to the spatial planar graph and displayed on the display screen 6.

[0035] Once the settlement of the settlement observation reference points and the inclination angle of the steel structure shaft exceed the threshold values set in the controller 3 in advance (for example, the settlement of the settlement observation reference points exceeds 20 mm, and the inclination angle exceeds 15°), the controller 3 controls the prompt light 4 to flash and the buzzer 5 to emit a prompt.

[0036] The wireless signals of the settlement and the inclination angle of the steel structure shaft 100 are sent to the mobile terminal devices of the staff, such as mobile phones, tablet computers, etc., through the wireless communication module 7, so that the relevant staff can find the problems in time.

[0037] It should be noted that the above-mentioned method of constructing three spatial coordinates and the mathematical calculation method of determining a spatial planar graph according to three spatial coordinates are prior art, and the present application does not involve the improvement of computer programs.

[0038] Further, the above-mentioned optical distance measuring sensor 2 can also adopt an infrared distance measuring sensor.

[0039] Further, the above-mentioned wireless communication module 7 can also adopt any one or a combination of several of a 3G communication module, a 4G communication module, a Nb-IoT communication module, and a Zigbee communication module.
