Description

Technical Field

[0002] Developed from total stations, intelligent total stations are easy to use and offer a higher degree of automation in target search, tracking, identification, and capture. They offer high accuracy in angle and distance measurement, and the measurement accuracy of the station's local coordinate system can reach the millimeter level. They are widely used in automated deformation monitoring. In previous automated deformation monitoring, stations were generally assumed to be stable. However, due to various factors, station locations can change. In this case, using fixed station coordinates to calculate monitoring point coordinates during each monitoring period can lead to inaccurate monitoring results. Therefore, there is room for improvement in the accuracy of traditional automated deformation monitoring methods. If an inverted device can be connected to stable bedrock as a reference for the station location, the station coordinates can be promptly corrected, and the corrected station coordinates can be used to calculate the monitoring point coordinates. This approach can ensure the accuracy of monitoring results even when the station location changes. This approach is particularly suitable for monitoring tasks where station location stability is poor. Summary of the Invention

[0050] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0051] In previous automated deformation monitoring, it was generally believed that the measuring station was stable. However, due to various factors, the measuring station may also change. At this time, if the fixed measuring station coordinates are still used to calculate the monitoring point coordinates in each monitoring period, the monitoring results will be incorrect and the test accuracy will be low.

[0052] It is understandable that, based on the defects in the background technology, the embodiment of the present invention provides an intelligent total station automatic deformation monitoring method in an unstable station environment, specifically Figure 1 Said method comprises the following steps:

[0053] Get the horizontal change of the measuring station;

[0054] Get the vertical change of the measuring station;

[0055] Add the changes of the measuring station in the horizontal and vertical directions to the original measuring station coordinates to obtain the corrected measuring station coordinates;

[0056] The observation values ​​of each monitoring point include the station coordinates after the joint correction of the slant distance, horizontal angle and vertical angle, and the current coordinate value of each monitoring point is calculated. The current coordinate value of each monitoring point is compared with the coordinate value of the previous period to obtain the new deformation, and deformation analysis is performed based on the new deformation.

[0057] It should be noted that the embodiment of the present invention uses an intelligent total station in conjunction with a prism to automatically monitor the monitoring area, and sets up an inverted device near the measuring station to judge the stability of the measuring station and make necessary corrections to the measuring station coordinates. The corrected measuring station coordinates are combined with the observation values ​​of each period to calculate the coordinates of each monitoring point and perform deformation analysis. This method can ensure the reliability of the measurement results, and can ensure the accuracy of the monitoring results even when setting up stations in locations with poor geology, and has good technical effects.

[0058] Specifically, before performing automated deformation monitoring, preparation work is also required, which includes the following steps:

[0059] Instrument placement: Set up the intelligent total station on the observation pier of the survey station with known coordinates, take the plumb line as the z-axis and the orientation direction as the x-axis, and establish the coordinate system o-xyz. Its coordinates are set as (x s ,y s , z s ), place the prism at the known backsight point, whose coordinates are (x r ,y r , z r ), prisms are placed on each observation pier in the monitoring area as monitoring points;

[0060] It should be noted that when setting up the intelligent total station on the observation pier at the measuring station, the relevant settings should be completed and the learning measurement of the monitoring point should be completed.

[0061] Set up the inverted pendant device: The inverted pendant device is set up near the measuring station and forms a whole with the observation pier of the measuring station. The lower part of the pendant is anchored to the stable bedrock, and a floating device is set up on the upper part.

[0062] An embodiment of the present invention provides an automated deformation monitoring method using an intelligent total station, which specifically includes the following steps:

[0063] Correction of the measuring station coordinates: Before the jth period (j = 1, 2, 3, ...) of automated monitoring, the horizontal change Δx of the measuring station is determined by the inverted reading device. j , Δy j , determine the vertical change Δz of the measuring station by aiming the prism on the inverted device of the intelligent total station j , correct the station coordinates to get the new station coordinates in,

[0064]

[0065]

[0066]

[0067] Among them, x s ,y s , z s They represent the initial coordinates of the observation pier of the measuring station on the xyz axis, Δx j , Δy j represents the horizontal change of the j-th observation station; Δz j It represents the change in the vertical direction of the j-th measuring station.

[0068] In this embodiment, Figure 2 Schematic diagram of the correction of the measuring station coordinates x and y provided by the embodiment of the present invention; Figure 2As shown in the figure, since the measuring station is unstable, displacement will occur. The steel wire passes through the small hole in the middle of the inverted reading device. The inverted reading device and the observation pier of the measuring station form a whole. The displacement change in the x and y directions output by the inverted reading device is the change Δx in the x and y directions of the measuring station. j , Δy j .

[0069] At the same time, a prism is set on the steel wire, and the prism is regularly aimed at by the intelligent total station. Since the steel wire is stable and does not move, the change in the vertical direction is obtained by the intelligent total station. Figure 3 Schematic diagram of station coordinate z correction provided by an embodiment of the present invention; specifically as Figure 3 As shown in FIG, obtaining the vertical change of the measuring station coordinates includes the following steps:

[0070] First, measure the original slant distance s1 from the center of the intelligent total station to the prism on the inverted wire and the initial vertical angle β1 between the observation pier and the prism;

[0071] Then measure the slant distance s from the center of the j-th intelligent total station to the prism on the inverted wire j and the vertical angle β between the j-th observation tower and the prism j changes;

[0072] Use the geometric model to calculate the change in the coordinates of the measuring station in the z direction Δz j The specific expression of the geometric model is:

[0073] Δz j =s j cosβ j -s1cosβ1

[0074] The coordinate change of the measuring station is (Δx j , Δy j , Δz j ), add the station coordinate change to the original station coordinate to get the corrected station coordinate

[0075] Calculation and analysis of monitoring point coordinates: The intelligent total station calculates the observation values ​​of each monitoring point i (i = 1, 2, 3...h) in the jth period, including the slope distance horizontal angle vertical angle Combine the corrected station coordinates to calculate the current coordinate values ​​of each monitoring point And compare with the previous coordinates to get the new deformation;

[0076] In the embodiment of the present invention, obtaining the new deformation specifically includes:

[0077] Calculate the quadrant angle from the survey station to the backsight point;

[0078] Calculate the coordinate azimuth from the measuring station to the backsight point through the quadrant angle;

[0079] Calculate the coordinate azimuth from the measuring station to the monitoring point;

[0080] The coordinates of the monitoring point are obtained through the coordinate azimuth, slant distance and vertical angle from the measuring station to the monitoring point.

[0081] The quadrant angle r from the station to the backsight point is expressed as:

[0082]

[0083] Calculate the coordinate azimuth from the measuring station to the backsight point This includes the following situations:

[0084] (1) When the backsight point is in the first quadrant,

[0085] (2) When the backsight point is in the second or third quadrant,

[0086] (3) When the backsight point is in the fourth quadrant,

[0087] Calculate the coordinate azimuth from the measuring station to the monitoring point i

[0088]

[0089] The coordinates of the monitoring point are:

[0090]

[0091]

[0092]

[0093] in, They represent the coordinates of the i-th monitoring point in the j-th period, represents the slant distance from the j-th monitoring station to the i-th monitoring point, represents the vertical angle from the j-th measuring station to the i-th monitoring point, represents the coordinate azimuth from the j-th measuring station to the i-th monitoring point, They represent the coordinates of the j-th measuring station respectively.

[0094] Finally, the current coordinate values ​​of each monitoring point are compared with the previous coordinate values ​​to obtain the new deformation. Based on the new deformation, deformation analysis is performed. If the deformation exceeds the specified limit, the cause of the deformation needs to be found.

[0095] Specifically, the step of comparing the current coordinate value of each monitoring point with the previous coordinate value to obtain a new deformation includes: subtracting the previous coordinate value from the current coordinate value, and the obtained difference is the new deformation value.

[0096] It should be noted that after obtaining the new deformation, the backsight point coordinates are corrected. If the backsight point is unstable, the backsight point coordinates can be corrected by setting up an inverted device and then used to calculate the monitoring point coordinates.

[0097] According to the second aspect of the present invention, an embodiment of the present invention further proposes an intelligent total station automatic deformation monitoring device, which is applied to the above-mentioned intelligent total station automatic deformation monitoring method, specifically as follows: Figure 4 The diagram shows the coordinates of the measuring station using inverted correction. The monitoring device includes:

[0098] The plumb line device includes a plumb line made of steel wire, and a prism is set on the plumb line as a vertical reference of the measuring station;

[0099] The upper end of the inverted device is connected to the float in the hydraulic oil barrel, and the lower end is anchored to the stable bedrock, so as to obtain the horizontal change of the measuring station;

[0100] The intelligent total station is installed on the observation pier of the survey station and is used to obtain the vertical change of the survey station.

[0101] Specifically, in Figure 4 The plumb line device consists of a hydraulic oil drum, a prism, a float, a connecting rod, a shelf, a plumb line, and an anchor block. The float is located inside the hydraulic oil drum and connected by a plumb line. A prism is placed on the plumb line as the vertical reference for the survey station. A plumb reading device is located below the prism. The station observation pier and the plumb reading device are integrally formed. The plumb line device's lower end is anchored to stable bedrock by an anchor block, ensuring stability. The plumb line's upper end is connected to the float within the hydraulic oil drum. Due to the buoyancy of the float within the hydraulic oil drum, the plumb line is pulled taut by the float, thus serving as the horizontal reference for the survey station. The plumb line is constructed from steel wire, which is indium steel, a material with a low linear expansion coefficient. This reduces thermal expansion and contraction, as well as elongation or shortening due to stress. A prism is placed on the wire as the vertical reference for the survey station. The x- and y-axis changes read by the plumb reading device are consistent with the coordinate system used for automated monitoring. Since the survey station's movement is minimal, rotational changes are ignored.

[0102] The technical solution of the present invention is further specifically illustrated below through embodiments and in conjunction with the accompanying drawings.

[0103] In the monitoring of a certain reservoir dam, it is difficult to find a stable measuring station. Using the method mentioned in the present invention, an inverted device is set near the measuring station. First, it is assumed that the measuring station has not changed, and the parameter value of the monitoring point is obtained through the observation data. Thus the coordinates of the monitoring point are calculated; then the horizontal change Δx of the first and second periods is obtained using the inverted reading device j , Δy j , determine the vertical change Δz of the measuring station by aiming the prism on the inverted device of the intelligent total station j , use the displacement change to correct the coordinates of the measuring station, recalculate the coordinates of the monitoring point, and compare the calculation results to evaluate the test effect. In this embodiment of the present invention, the initial coordinates of the monitoring point are set as the first phase coordinates.

[0104] The monitoring test is as follows: 1. Required equipment

[0105] 1 TM60 intelligent total station, 4 prisms, 1 inverted pendulum device, and 1 inverted pendulum reading device.

[0106] 2. Operation methods and data recording

[0108] First, complete the relevant settings in the intelligent total station and complete the learning measurement of the monitoring point. Under the assumption that the measuring station is stable and motionless, the coordinates of the monitoring point are calculated using the monitoring data; then, the horizontal change Δx of the measuring station is determined by the inverted reading device. j , Δy j , determine the vertical change Δz of the measuring station by aiming the prism on the inverted device of the intelligent total station j , correct the measuring station coordinates, use the corrected data to recalculate the monitoring point coordinates, and compare the calculation results, as follows:

As the automated deformation monitoring proceeds, the difference under the two different conditions will become more and more obvious.
