[0027] In order to make the purpose, technical solutions and advantages of this application more clear, the following further describes this application in detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0028] To explain in detail the structure and functions of the diversion well filling material settlement measurement terminal of the present application, a detailed description will be given in the following embodiments.

[0029] In one embodiment, Figure 1 As shown, a diversion well filling settlement measurement terminal is provided, comprising: a satellite positioning unit 200, a settlement measurement rod unit 400 and a data transmission unit 600;

[0030] The settlement measuring rod unit 400 is set at the wellhead monitoring point of the diversion well, and the satellite positioning unit 200 is set at the settlement measuring rod unit 400;

[0031] The satellite positioning unit 200 uses satellite positioning to locate the geographical coordinates of the wellhead monitoring point, and reports the geographical coordinates of the wellhead monitoring point through the data transmission unit 600; the settlement measurement rod unit 400 collects the settlement change data of the filling material in the diversion well, and reports the settlement change data through the data transmission unit 600.

[0032] The satellite positioning unit 200 refers to a unit that realizes positioning by adopting satellite positioning technology. Satellite positioning technology is a technology that accurately locates an object by using satellites. It determines the position of the receiver by utilizing two-way communication between the satellite and the receiver, and can provide users with accurate position coordinates and related attribute characteristics in real time on a global scale, including navigation, positioning, timing and other functions. Specifically, the satellite positioning unit 200 locates the geographic coordinates of the wellhead monitoring point by using satellite positioning, and reports the geographic coordinates of the wellhead monitoring point through the data transmission unit 600. Further, the satellite positioning unit 200 can perform positioning based on Beidou satellite signals, GPS signals, etc., that is, the satellite positioning unit 200 can include but is not limited to Beidou positioning units, GPS positioning units, etc.

[0033] The settlement measuring rod unit 400 is used to measure the settlement change data of the diversion well. It is specifically set at the wellhead monitoring point of the diversion well, and the satellite positioning unit 200 is set on the settlement measuring rod unit 400. Specifically, the settlement measuring rod unit 400 may include multiple sensors, and different sensors detect the settlement change data of the diversion well filling and report the settlement change data through the data transmission unit 600. Figure 2 As shown, the settlement measuring rod unit 400 may include a horizontal displacement monitoring sensor 420 and a settlement monitoring sensor 460 , wherein the horizontal displacement monitoring sensor 420 is used to detect the tilt angle of the measuring rod 440 , and the settlement monitoring sensor 460 is used to detect the sinking depth of the measuring rod 440 .

[0034] The data transmission unit 600 is used to report settlement change data and initial coordinates. It is connected to the settlement measuring rod unit 400. Specifically, the inclination angle and sinking depth of the measuring rod 440 detected by the settlement measuring rod unit 400, as well as the geographic coordinates of the wellhead monitoring point obtained by the satellite positioning unit 200, can be reported via the data transmission unit 600. More specifically, the data transmission unit 600 can report data via 4G, GPRS (General Packet Radio Service), and optical cable. Furthermore, the data transmission unit 600 can be a device such as a wireless network card.

[0035] The above-mentioned diversion well filling material settlement measurement terminal locates the geographic coordinates of the wellhead monitoring point using satellite positioning via the satellite positioning unit 200, and reports the geographic coordinates of the wellhead monitoring point via the data transmission unit 600. The settlement measurement rod unit 400 collects settlement change data of the filling material in the diversion well and reports the settlement change data via the data transmission unit 600. In the present application, the high-precision geographic coordinates of the wellhead monitoring point are obtained by positioning via the satellite positioning unit 200, and the settlement change data of the filling material in the diversion well is collected via the settlement measurement rod unit 400. The geographic coordinates of the wellhead monitoring point and the settlement change data of the filling material in the diversion well are reported via the data transmission unit 600. This achieves efficient transmission of settlement change data of the filling material in the diversion well, allowing monitoring personnel to monitor settlement changes of the diversion well filling material in a timely and efficient manner without on-site detection.

[0036] In one embodiment, the satellite positioning unit 200 uses a carrier phase difference method to locate the geographical coordinates of the wellhead monitoring point.

[0037] The carrier phase difference method involves real-time differential processing of carrier phase observations from two monitoring stations. This involves transmitting the carrier phase data collected by the base station to the user receiver, then calculating the difference between the carrier phase observations from the local and base stations to resolve coordinates. This method can eliminate satellite and receiver clock errors, mitigate the effects of ionospheric and tropospheric refraction, and eliminate integer ambiguity parameters, thereby improving positioning accuracy.

[0038] Specifically, the satellite positioning unit 200 includes a satellite antenna and a receiver. Taking the Beidou satellite positioning unit as an example, two (or more) Beidou receivers are respectively placed at the two ends of one (or more) baselines, and the same Beidou satellites are synchronously observed to determine the relative position of the baseline endpoints or the baseline vector. This application uses the satellite antenna set at the wellhead monitoring point as the positioned target and the receiver as the ground reference station. By taking the difference between the carrier phase observation values ​​of the positioned target and the ground reference station, the calculated positioning point coordinates, that is, the initial geographic coordinate values ​​of the wellhead monitoring point, are obtained, thereby realizing high-precision measurement of the initial coordinates of the wellhead monitoring point.

[0039] Furthermore, the satellite positioning unit 200 may be, but is not limited to, a Beidou satellite positioning unit, a GPS (Global Positioning System) positioning unit, or the like.

[0040] In one embodiment, Figure 2 As shown, the settlement measuring rod unit 400 includes a measuring rod 440, a horizontal displacement monitoring sensor 420 and a settlement monitoring sensor 460; the horizontal displacement monitoring sensor 420 and the settlement monitoring sensor 460 are arranged on the measuring rod 440, and the settlement monitoring sensor 460 is immersed in the filling in the diversion well.

[0041] Measuring rod 440 is a measuring tool that serves as a reference. Horizontal displacement monitoring sensor 420 uses observation instruments and equipment to measure the horizontal displacement of representative points. In this application, horizontal displacement monitoring sensor 420 is used to measure the tilt angle change data of measuring rod 440. Settlement monitoring sensor 460 observes set observation points and fixed measurement points, and the monitored settlement degree is expressed in data. In this application, settlement monitoring sensor 460 is used to measure the vertical change of measuring rod 440.

[0042] Specifically, the settlement measurement rod unit 400 comprises a measuring rod 440, a horizontal displacement monitoring sensor 420, and a settlement monitoring sensor 460. The horizontal displacement monitoring sensor 420 is mounted on the measuring rod 440, while the settlement monitoring sensor 460 is located on the portion of the measuring rod 440 that is submerged in the diversion well filling. The measuring rod 440 is used to compare its initial position with its position after settlement, while the horizontal displacement monitoring sensor 420 and the settlement monitoring sensor 460 measure this comparison, facilitating real-time monitoring of the diversion well filling's settlement.

[0043] In one embodiment, the bottom end of the measuring rod 440 is inserted into the filler in the diversion well, the top end of the measuring rod 440 is at the wellhead monitoring point of the diversion well, the settlement monitoring sensor 460 is arranged on the measuring rod 440 and immersed in the filler in the diversion well, and the satellite positioning unit 200 is arranged at the top end of the measuring rod 440.

[0044] Specifically, the settlement monitoring sensor 460 needs to be immersed in the filling inside the diversion well in order to better monitor the settlement changes of the filling in the vertical direction. The settlement monitoring sensor 460 is set on the measuring rod 440, and the top of the measuring rod 440 is located at the wellhead monitoring point of the diversion well, that is, the coordinates of the top of the measuring rod 440 are the initial coordinates of the wellhead monitoring point, which is conducive to solving the initial coordinates of the settlement monitoring point located at the settlement monitoring sensor 460 through the coordinates of the top of the measuring rod 440.

[0045] In one embodiment, Figure 2 As shown, the horizontal displacement monitoring sensor 420 is used to detect the tilt angle of the measuring rod 440 after settlement, and the settlement monitoring sensor 460 is used to detect the sinking depth of the measuring rod 440 after settlement.

[0046] The z-axis is perpendicular to the plane of the wellhead, the x-axis is horizontal to the plane of the wellhead, and the y-axis is perpendicular to the x and z-axes in the plane of the wellhead. The tilt angle refers to the angle relative to the x, y, and z axes in this xyz rectangular coordinate system. The sinking depth refers to the sinking depth of the settlement monitoring sensor 460 mounted on the measuring rod 440 as the measuring rod 440 sinks.

[0047] Specifically, in the xyz rectangular coordinate system, the horizontal displacement monitoring sensor 420 measures that the inclination angle of the measuring rod 440 with respect to the x, y, and z axes when the measuring rod 440 is installed in the landfill is θ x0 ,θ y0 ,θ z0 After settling, the inclination angle of the measuring rod 440 with the x, y, and z axes is θ x1 ,θ y1 ,θ z1 The settlement monitoring sensor 460 is used to detect the sinking depth of the measuring rod 440 after the filling material settles.

[0048] In one embodiment, Figure 2 As shown, the settlement monitoring sensor 460 includes a pin-type settlement monitoring sensor 460 .

[0049] Among them, the axle pin is a type of standardized fastener that can be used for static fixed connection or relative movement with the connected parts. It is mainly used at the hinge of two parts to form a hinge connection.

[0050] Specifically, the pin-type settlement monitoring sensor 460 forms a hinge connection between the settlement monitoring sensor 460 and the measuring rod 440, so as to facilitate relative or stationary movement of the settlement monitoring sensor 460.

[0051] In one embodiment, the axial pin type settlement monitoring sensor 460 includes a settlement monitoring anchor and an encoder. The settlement monitoring anchor is connected to the measuring rod 440 by an axial pin. The settlement monitoring anchor is immersed in the filler in the diversion well. The encoder is used to count the number of rotations of the settlement monitoring anchor around the axial pin.

[0052] The settlement monitoring anchor is a slender rod that is passively loaded when the soil deforms. An encoder is a sensor used to measure mechanical rotation or displacement. It measures the position or speed of a mechanical component during rotation or linear motion, converts it into a series of electrical signals, and displays it. The encoder in this application is used to count the number of revolutions of the settlement monitoring anchor around the axle pin.

[0053] Specifically, the initial coordinates of the position of the settlement monitoring sensor 460 are the initial coordinates of the filling settlement monitoring point. The settlement monitoring sensor 460 uses a settlement monitoring anchor to detect the sinking depth of the measuring rod 440, and the settlement monitoring anchor is also immersed in the filling inside the diversion well. Since the connection between the settlement monitoring anchor and the measuring rod 440 is a pin-type connection, when the filling settles, the settlement monitoring anchor connected to the measuring rod 440 in a pin-type manner and immersed in the filling also settles. Therefore, the present application can monitor the vertical settlement changes of the filling layer through the rotation range of the settlement monitoring anchor around the pin. The encoder is set at the settlement monitoring anchor. When the settlement monitoring anchor rotates one circle around the pin, the vertical drop of the filling layer is detected to be d; when the settlement monitoring anchor rotates n circles around the pin, the vertical drop of the filling layer is detected to be D=nd.

[0054] In one embodiment, Figure 3 As shown, the diversion well settlement measurement terminal also includes a host computer 800; the host computer 800 is connected to the data transmission unit 600; the host computer 800 receives the geographical coordinates of the wellhead monitoring point and the settlement change data of the filling in the diversion well, and obtains the settlement displacement of the diversion well filling based on the geographical coordinates of the wellhead monitoring point and the settlement change data of the filling in the diversion well.

[0055] The host computer 800 is a computer that can directly issue control commands, typically a PC. The screen displays various signal data changes, such as hydraulic pressure, water level, and temperature. The slave computer reads the device status data (typically analog), converts it into digital signals, and feeds it back to the host computer 800. The host computer 800 receives the feedback digital signals. The settlement change data received by the host computer 800 in this application includes the inclination angle of the measuring rod 440 relative to the x, y, and z axes after settlement, as well as the depth of the measuring rod 440. The settlement displacement of the diversion well filling material includes both horizontal and vertical displacements of the filling material.

[0056] Specifically, the geographical coordinates of the wellhead monitoring point and the settlement change data of the filling material in the diversion well are transmitted to the host computer 800 through the data transmission unit 600. The host computer 800 calculates the horizontal and vertical displacement of the diversion well settlement based on the received geographical coordinates of the wellhead monitoring point and the settlement change data of the filling material in the diversion well.

[0057] In one embodiment, the host computer 800 is also used to obtain the installation parameters corresponding to the settlement measuring rod unit 400; and obtain the settlement displacement of the diversion well filling material based on the geographical coordinates of the wellhead monitoring point, the settlement change data of the filling material in the diversion well, and the installation parameters.

The host computer 800 calculates the horizontal and vertical displacement of the diversion well settlement based on the received geographical coordinates of the wellhead monitoring point, the settlement change data of the filling material in the diversion well, and the installation parameters.

[0060] Specifically, the host computer 800 obtains the initial coordinates of the settlement monitoring point according to the geographical coordinates and installation parameters of the wellhead monitoring point, including:

[0061] Assume that the initial coordinates of the wellhead monitoring point are (x0, y0, z0) and the initial coordinates of the settlement monitoring point are (x1, y1, z1);

[0067] The y-axis coordinate of the settlement monitoring point is: y1=y0+△y0=y0+L0cosθ y0 .

[0068] When the bottom end of the measuring rod 440 is in the second quadrant of the xy plane,

[0069] The x-axis coordinate of the settlement monitoring point is: x1 = x0 - △x0 = x0 - L0cosθ x0 ;

[0070] The y-axis coordinate of the settlement monitoring point is: y1=y0+△y0=y0+L0cosθ y0 .

[0071] When the bottom end of the measuring rod 440 is in the third quadrant of the xy plane,

[0072] The x-axis coordinate of the settlement monitoring point is: x1 = x0 - △x0 = x0 - L0cosθ x0 ;

[0073] The y-axis coordinate of the settlement monitoring point is: y1 = y0 - △y0 = y0 - L0cosθ y0 .

[0076] The y-axis coordinate of the settlement monitoring point is: y1 = y0 - △y0 = y0 - L0cosθ y0 .

[0077] According to the initial coordinates of the wellhead monitoring point and the projections of the position of the settlement monitoring point on the x-axis and the y-axis, the host computer 800 obtains the initial coordinates of the settlement monitoring point after calculation.

[0078] Specifically, based on the initial coordinates of the wellhead monitoring point and the settlement change data of the diversion well filling material, the host computer 800 obtains the settlement coordinates of the settlement monitoring point after the diversion well filling material settles, including:

[0079] Assuming that the settlement coordinates of the settlement monitoring point after the diversion well filling material settles are (x2, y2, z2), calculate the z-axis coordinates of the settlement monitoring point.

[0080] Among them, h1 is the distance between the upper fixed point of the settlement monitoring anchor and the wellhead monitoring point, The vertical settlement of the settlement monitoring anchor is △h = h1-h0;

[0081] When the bottom end of the measuring rod 440 is in the first quadrant of the xy plane, the x and y coordinates of the settlement monitoring point are calculated.

[0082] The signs of the remaining quadrants change in the same way. The host computer 800 obtains the coordinates of the settlement monitoring points after settlement through calculation.

[0083] Specifically, according to the initial coordinates of the settlement monitoring point and the settlement coordinates of the settlement monitoring point, the step of the host computer 800 obtaining the settlement displacement includes:
