Detailed Description
Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.
The following describes a method and an apparatus for detecting the settlement of a substation base, an electronic device, and a storage medium according to embodiments of the present invention with reference to the accompanying drawings.
Fig. 1 is a flow chart of a substation base settlement detection method according to an embodiment of the present invention. As shown in fig. 1, the method comprises the steps of:
step S110: and acquiring the three-dimensional coordinate values of each monitoring station.
In the embodiment of the invention, a plurality of monitoring stations are arranged on a base of the transformer substation, and a differential reference station is also arranged in the transformer substation. Wherein, the differential reference station and the plurality of monitoring stations can adopt GNSS receivers. In addition, the number of monitoring stations is at least 3.
The satellite transmits satellite positioning data to the monitoring station and the differential reference station in a broadcasting mode; the difference reference station can improve the data accuracy of the obtained satellite positioning data from a centimeter level to a millimeter level, and then the accuracy of the three-dimensional coordinate value obtained by subsequent calculation can be improved.
In some embodiments, the number of the monitoring stations is 4, and the monitoring stations are respectively arranged corresponding to four corners of the base. Specifically, if the base is rectangular, the monitoring stations can be arranged at four corners of the base respectively, and after the positions of the monitoring stations are connected together as much as possible, the formed centroid of the geometric plane can coincide with the centroid of the base plane. Because the position of the differential reference station needs to meet the requirement of immobilization, the differential reference station can be arranged in a transformer substation at a stable position, and signals can cover the position of the whole detection area (namely the whole transformer substation base).
In step S110, both the differential reference station and the monitoring station may observe the satellite navigation signal to obtain satellite positioning data, where the satellite positioning data at least includes carrier phase data, pseudorange observation value, and coordinate data. After the differential reference station obtains the carrier phase data, the pseudo-range observation value and the coordinate data of the differential reference station, the differential reference station sends the data to a position resolving server; similarly, each monitoring station transmits the obtained carrier phase data, pseudo-range observation values and coordinate data of the monitoring station to the position calculation server. And the position calculation server calculates the three-dimensional coordinate value of each monitoring station according to the carrier phase data, the pseudo-range observation value, the coordinate data of the differential reference station and the coordinate data of the monitoring station.
In some embodiments, a position calculation algorithm may be run on the position calculation server, and the carrier phase data, the pseudo-range observation value, the coordinate data of the differential reference station, and the coordinate data of the monitoring station are used as calculation parameters of the position calculation algorithm to obtain a three-dimensional coordinate value of each monitoring station. The position calculation algorithm run by the position calculation server may specifically be: real Time Kinematic carrier phase differential positioning (RTK).
The RTK technology eliminates the carrier pseudo-range deviation, the clock error of the monitoring station and the satellite clock error of the monitoring station by constructing dual-difference observed values between stations and satellites, greatly weakens the influence of satellite orbit error, atmospheric error and the like on the whole-cycle ambiguity search, enables the whole-cycle ambiguity to be quickly fixed, and obtains real-time high-precision three-dimensional coordinate values of each monitoring station. The specific position solution process of the RTK technique may refer to an existing RTK position solution process, and will not be described herein.
In the process of resolving the three-dimensional coordinate value, the resolving result is affected by various types of deviations, satellite geometric configurations and integer ambiguity fixing errors which are not eliminated in the observed value, so that the positioning accuracy may not reach the preset standard. In some embodiments, a coarse difference elimination method may be used to eliminate the deviation, so as to improve the precision of the obtained three-dimensional coordinate values.
Step S120: and determining the mass center coordinate value of the base according to the three-dimensional coordinate values of the monitoring stations.
After the three-dimensional coordinate values of all the monitoring stations are determined, the mass center coordinate values of the plane (namely the base plane) formed by the monitoring stations are obtained through the three-dimensional coordinate values of all the monitoring stations. In some embodiments, the monitoring computer may be used to call an access interface of the position calculation server to obtain the three-dimensional coordinate values of each monitoring station, and then the centroid coordinate values of the base may be obtained by operating a centroid coordinate calculation algorithm.
In some embodiments, the centroid coordinate values may be determined by:
wherein, X P 、Y P And Z P Is the coordinate value of mass center, n is the number of monitoring stations, i is the identification information of the monitoring stations, X i 、Y i And Z i And the three-dimensional coordinate values of the monitoring station.
It should be noted that, an identification information may be set for each monitoring station, so that the monitoring stations can be identified by the identification information. The identification information may be a numbered index of the monitoring station, e.g., "monitoring station 1#", "monitoring station 2#", etc.
The monitoring computer can operate the above calculation formula of the centroid coordinate value as a centroid coordinate calculation algorithm to obtain the centroid coordinate value of the base. After the centroid coordinate values are obtained, the centroid coordinate values may be stored in a memory of the monitoring computer as historical data.
It should be noted that the monitoring computer may acquire the three-dimensional coordinate value of each monitoring station from the position calculation server once every interval of one cycle, and then determine the centroid coordinate value of the cycle according to the three-dimensional coordinate value of each monitoring station. The period may be set according to actual detection requirements, and is not limited herein.
Step S130: and judging whether the base is settled according to the coordinate value of the mass center.
First, it should be noted that an initial centroid coordinate value of the substation base may be stored, and the initial centroid coordinate value may be used as a preset initial value. And after the three-dimensional coordinate values of all the monitoring stations are continuously obtained and the mass center coordinate value of the base is obtained by utilizing the three-dimensional coordinate values of all the monitoring stations, whether the base is settled or not can be judged by comparing the mass center coordinate value of the current base with a preset initial value.
As an example, after the substation base is built, by obtaining the three-dimensional coordinate values of each monitoring station, the initial centroid coordinate value of the base is obtained as (32.5,15.3,18.7), and the initial centroid coordinate value is stored. After the transformer substation is used for a long time, the centroid coordinate value of the current base is (32.6,15.1,13.7) obtained through the three-dimensional coordinate value of each monitoring station obtained this time, and the base can be known to be settled by comparing the centroid coordinate value of the current base with the initial centroid coordinate value.
To improve the accuracy of substation base settlement detection, as shown in fig. 2, in some embodiments, whether the base is settled may be determined by:
step S210: determining a centroid coordinate estimated value of the base according to the centroid coordinate value;
step S220: and judging whether the base is settled or not according to the estimated value of the centroid coordinate and a preset initial value.
Specifically, after the centroid coordinate value of the base is obtained, the centroid coordinate estimated value of the base can be determined according to the centroid coordinate value of the current period and the centroid coordinate value of the previous period, so that the centroid coordinate value of the current period and the centroid coordinate value of the previous period can be comprehensively considered, a trend of centroid coordinate change is obtained, whether the base is settled or not is further judged based on the change trend, and therefore deviation caused by operation errors is reduced.
In some embodiments, the centroid coordinate estimate may be determined by:
wherein the content of the first and second substances,
and
is the estimated value of the centroid coordinate of the t period base, P is the filter adjustment factor, X P 、Y P And Z P Are the centroid coordinate values.
It should be noted that the filter adjustment factor may be set or adjusted according to actual requirements, the value interval of P is [0,1], and the value of the filter adjustment factor is not specifically limited here.
Fig. 3 is a flow chart of a specific method of determining the subsidence of a foundation according to an embodiment of the present invention. As shown in fig. 3, in some embodiments, step S220 includes the steps of:
step S310: and determining the coordinate difference value of the centroid coordinate estimation value and a preset initial value.
Step S320: and judging whether the coordinate difference value exceeds a preset threshold value.
Step S330: and if so, determining that the base is settled.
Specifically, after the centroid coordinate estimation value of the base in the current period is obtained, a coordinate difference value is determined according to a previously stored preset initial value and the centroid coordinate estimation value of the current period. In some embodiments, the coordinate difference may be determined by:
wherein the content of the first and second substances,
and
is an estimate of the centroid coordinate of the t-period pedestal, X P (0)、Y P (0) And Z P (0) Is a preset initial value, T X 、T Y And T Z Is a preset threshold. Note that T is X 、T Y And T Z Can be manually set according to the monitoring requirement, and T X 、T Y And T Z The setting may be the same preset threshold value, or may be different preset threshold values.
As an example, T X 、T Y And T Z Are set to 0.2m, the preset initial value is (20.36,12.54,33.23), and the precision of the coordinates is millimeters. If the estimated value of the centroid coordinate of the pedestal in the current period is (20.21,12.43,33.06), obtaining the coordinate difference value through the calculation formula of the coordinate difference value
Thereby enabling a determination that the substation foundation has settled.
Therefore, the mass center coordinate value of the base is determined by acquiring the three-dimensional coordinate value of each monitoring station and according to the three-dimensional coordinate value of each monitoring station; obtaining a centroid coordinate estimation value according to the centroid coordinate value of the current period and the centroid coordinate value of the previous period; and judging whether the base is settled according to the estimated value of the centroid coordinate and a preset initial value. Because the barycenter coordinate value is obtained through the three-dimensional coordinate values of a plurality of monitoring stations, the barycenter coordinate value can represent the position of the whole base, and therefore the detection accuracy of foundation settlement detection can be improved.

As shown in fig. 4, the detecting apparatus 400 includes: the system comprises an acquisition module 410 for acquiring the three-dimensional coordinate values of each monitoring station, a determination module 420 for determining the centroid coordinate value of the base according to the three-dimensional coordinate values of each monitoring station, and a judgment module 430 for judging whether the base sinks according to the centroid coordinate value.
