BACKGROUND

[0002] Offshore photovoltaic units are large in size and are in a complex marine environment for a long time, and are more likely to displace, deform, and the like. For example, offshore photovoltaic supports are easily deformed by stress, seawater corrosion, and the like for a long time, affecting the service life of the supports. Therefore, it is necessary to monitor the displacement, deformation, and the like of offshore photovoltaics.

[0003] However, the above monitoring requires a reliable reference point. In a marine environment, the reference point itself is prone to deviation, resulting in reduced accuracy of the monitoring results. SUMMARY

[0019] Example embodiments of the present disclosure will be described more fully hereinafter with reference to the accompanying drawings.

[0020] The accompanying drawings, which are included to provide a further understanding of the disclosure and are incorporated in and constitute a part of this application, illustrate certain non-limiting embodiments of the present disclosure. In the drawings, some embodiments are shown in cross-section, and in plan, which are schematic illustrations. Identical or similar elements are referred to with identical or similar reference numerals throughout the specification. It should be noted that the features illustrated in the drawings can be used in any combination.

[0021] The size of the offshore photovoltaic unit is large, resulting in a high load of its support, and it is in a complex marine environment for a long time, and there is a high probability of displacement, deformation, etc. Therefore, it is necessary to monitor its displacement, deformation, etc.

[0022] However, the above monitoring requires a reliable reference point. In an offshore photovoltaic project, in order to monitor the situation of the offshore photovoltaic unit in a short distance, an offshore reference point needs to be set. The offshore reference point is in the marine environment, and itself is also subjected to stress, seawater corrosion, etc. and is prone to shift, resulting in a decrease in the accuracy of monitoring based on the offshore reference point.

[0023] In view of the above problems, the exemplary embodiments of the present disclosure provide a reference point calibration method for offshore photovoltaic, aiming to solve the problem that the shift of the reference point affects the monitoring result.

[0024] Figure 1 A schematic diagram of a reference point network system is shown. The reference point network system includes a plurality of reference points, forming a network structure. The number of offshore reference points is not less than 2, and the number of land reference points is also not less than 2. As shown, three offshore reference points are set, located in the offshore photovoltaic area, which are offshore reference point 101, offshore reference point 102, and offshore reference point 103. Two land reference points are set, located on land, which are land reference point 104 and land reference point 105. Figure 1 As shown, three offshore reference points are set, located in the offshore photovoltaic area, which are offshore reference point 101, offshore reference point 102, and offshore reference point 103. Two land reference points are set, located on land, which are land reference point 104 and land reference point 105.

[0025] In one embodiment, each reference point is not located on a line connecting any two other reference points, so the relative orientation between any two reference points is unique. For example, when maritime reference point 101 receives calibration signals from other reference points, it can determine which reference point each calibration signal originated from based on the direction of the calibration signal. Preventing two other reference points from traveling in the same direction can reduce signal interference and confusion.

[0026] Figure 2 A schematic diagram showing offshore benchmarks. Figure 2 As shown, an offshore benchmark can be a site located at sea and includes a benchmark pile 201, a protective pile 202, a workbench 203, and a benchmark device 204. The benchmark pile 201 is a core support structure used to securely support the benchmark device 204. It can be made of materials such as concrete and driven into the seabed for fixation. One or more layers of protective piles 202 are provided outside the benchmark pile 201 to isolate the benchmark pile 201 from the seawater, thereby reducing the impact of the seawater on the benchmark pile 201, minimizing its positional deviation, and ensuring stability and reliability. The workbench 203 is used for manual operations. The benchmark device 204 can serve as a benchmark, such as a GNSS (Global Navigation Satellite System) benchmark device that can transmit calibration signals to and from the GNSS benchmark devices at other benchmark points. In addition, offshore benchmarks can also include monitoring equipment, such as meteorological monitoring equipment and video surveillance equipment.

[0027] Figure 3 An exemplary process of a benchmark calibration method for offshore photovoltaics is shown, including the following steps S310 to S330:

[0028] Step S310, determining first calibration data for each reference point based on calibration signals transmitted between each reference point and other reference points in the current cycle;

[0029] Step S320, determining whether the offshore reference point has shifted by comparing the first calibration data of each reference point with the reference calibration data, and using the offshore reference point that has shifted as the reference point to be calibrated;

[0030] Step S330 , calibrating the position of the reference point to be calibrated according to the first calibration data of the reference point to be calibrated.

[0031] based on Figure 3The method is to determine the first calibration data of each reference point based on the calibration signal transmitted between each reference point and other reference points in the current cycle; by comparing the first calibration data of each reference point with the reference calibration data, it is determined whether the offshore reference point has shifted, and the offshore reference point that has shifted is used as the reference point to be calibrated; based on the first calibration data of the reference point to be calibrated, the position of the reference point to be calibrated is calibrated. On the one hand, a calibration scheme for offshore reference points is provided, which can effectively calibrate the position of the offshore reference point in a timely manner after the position of the offshore reference point shifts, so as to ensure the accuracy of monitoring based on the offshore reference point. On the other hand, this scheme does not require major modifications to the offshore reference points, and the calibration effect can be achieved based on conventional hardware configuration, effectively controlling the implementation cost of the scheme.

[0032] Below Figure 3 Provide detailed instructions for each step.

[0033] refer to Figure 3 In step S310, first calibration data of each reference point is determined based on the calibration signal transmitted between each reference point and other reference points in the current cycle.

[0034] The calibration of the reference points can be performed periodically, such as once a day or other specified duration. The first calibration data can include relative position data between different reference points. Calibration signals in the form of microwaves, for example, can be transmitted between the different reference points. The relative positions of the different reference points are determined based on the calibration signals to obtain the first calibration data.

[0035] In one embodiment, the current cycle includes multiple time periods corresponding to each reference point. The method of determining the first calibration data of each reference point based on the calibration signal transmitted between each reference point and other reference points in the current cycle includes the following steps:

[0036] At different moments in any time period, the reference point corresponding to the time period is controlled to receive calibration signals sent by other reference points, and the first calibration data of the reference point is determined according to the calibration signals.

[0037] In each time period, the calibration signal transmitted by the corresponding reference point is received by the other reference points, while the other reference points can only transmit signals without receiving signals. Further, each time period can be divided into multiple sub-time periods corresponding to the other reference points, and in each sub-time period, a signal is transmitted by one of the other reference points. For example, the reference point network system includes five reference points, and each cycle is divided into five time periods, where time period 1 corresponds to sea reference point 101, time period 2 corresponds to sea reference point 102, time period 3 corresponds to sea reference point 103, time period 4 corresponds to land reference point 104, and time period 5 corresponds to land reference point 105. Each time period is further divided into four sub-time periods, such as time period 1 being divided into sub-time period 1-1, sub-time period 1-2, sub-time period 1-3, and sub-time period 1-4, corresponding to sea reference point 102, sea reference point 103, land reference point 104, and land reference point 105, respectively. In sub-time period 1-1, sea reference point 102 transmits a signal, which is received by sea reference point 101, and the signal received by sea reference point 101 is referred to as a calibration signal. In sub-time period 1-2, sea reference point 103 transmits a signal, which is received by sea reference point 101. In sub-time period 1-3, land reference point 104 transmits a signal, which is received by sea reference point 101. In sub-time period 1-4, land reference point 105 transmits a signal, which is received by sea reference point 101. Similarly, in sub-time period 2-1, sea reference point 101 transmits a signal, which is received by sea reference point 102, and the signal received by sea reference point 102 is referred to as a calibration signal. In sub-time period 2-2, sea reference point 103 transmits a signal, which is received by sea reference point 102. In sub-time period 2-3, land reference point 104 transmits a signal, which is received by sea reference point 102. In sub-time period 2-4, land reference point 105 transmits a signal, which is received by sea reference point 102.

[0038] In this way, multiple reference points do not simultaneously transmit and receive signals, which avoids signal interference and ensures that the transmission and reception of signals are orderly, thereby improving the calibration efficiency and accuracy of the reference points.

[0039] In an embodiment, referring to Figure 4 The determination of the first calibration data of each reference point based on the calibration signals transmitted between the reference point and the other reference points in the current cycle includes the following steps S410 and S420:

[0040] In step S410, the current relative position vector between each reference point and the other reference points is determined based on the calibration signals transmitted between the reference point and the other reference points in the current cycle.

[0041] In step S420, the current relative position vector is arranged in the order of the multiple reference points to obtain the first calibration data.

[0042] The direction, intensity, time, etc. of the calibration signal received by each reference point can be analyzed to determine the current relative position vector between different reference points, which represents the relative position between different reference points in the current period. The current relative position vector is arranged in the order of the plurality of reference points, such as the order of the offshore reference point 101, the offshore reference point 102, the offshore reference point 103, the land reference point 104, and the land reference point 105, to obtain the first calibration data.

[0043] For example, the offshore reference point 101 receives four calibration signals, and the current relative position vectors of the other four reference points relative to the offshore reference point 101 are analyzed and recorded as P 12 , P 13 , P 14 , and P 15 , where P 12 represents the current relative position vector of the offshore reference point 102 relative to the offshore reference point 101. The first calibration data of the offshore reference point 101 is obtained by arranging the reference points in order and adding the self item, which is (P 11 , P 12 , P 13 , P 14 , and P 15 ). Similarly, the first calibration data of the offshore reference point 102 is (P 21 , P 22 , P 23 , P 24 , and P 25 ). And so on.

[0044] Continuing to refer to Figure 3 , in step S320, by comparing the first calibration data of each reference point with the reference calibration data, it is determined whether the offshore reference point has deviated, and the offshore reference point that has deviated is taken as the reference point to be calibrated.

[0045] The reference calibration data is the calibration data of the reference point at a previous time earlier than the current period, such as the calibration data of the previous period. For example, the first calibration data obtained in step S310 in the previous period can be taken as the reference calibration data.

[0046] Therefore, by comparing the first calibration data of the current period with the reference calibration data, it can be detected whether the current position of the offshore reference point has changed compared with the previous time, i.e., whether the offshore reference point has deviated, and the offshore reference point that has deviated is taken as the reference point to be calibrated.

[0047] In one embodiment, the reference calibration data comprises reference relative position vectors between different reference points. The reference relative position vectors represent relative position vectors of the different reference points at a previous time, such as the relative position vectors of the last cycle. The reference relative position vectors serve as a reference to measure whether the current relative position vectors have changed.

[0048] Reference is made to Figure 5 As shown in the above, the determination of whether the offshore reference points have deviated by comparing the first calibration data of each reference point with the reference calibration data comprises the following steps S510 and S520:

[0049] Step S510, determine the current relative position vectors different from the reference relative position vectors by comparing the first calibration data of each reference point with the reference calibration data.

[0050] Step S520, determine whether the offshore reference points have deviated according to the reference points corresponding to the current relative position vectors different from the reference relative position vectors.

[0051] For example, let (P 11 ',P 12 ',P 13 ',P 14 ',P 15 ') represent the reference calibration data of the offshore reference point 101, wherein P 11 ',P 12 ',P 13 ',P 14 ',P 15 ' are the reference relative position vectors, such as P 12 ' represents the relative position vector of the offshore reference point 102 with respect to the offshore reference point 101 at a previous time. By comparing (P 11 ,P 12 ,P 13 ,P 14 ,P 15 ) with (P 11 ',P 12 ',P 13 ',P 14 ',P 15 '), find the case where the current relative position vector is different from the reference relative position vector, such as P 12 is different from P 12 ', then P 12P12 is added to the change vector set, and P12 corresponds to the sea reference point 101 and the sea reference point 102. According to this, it can be determined that the sea reference point 101 or the sea reference point 102 has deviated. By using this method, all the current relative position vectors of the changed reference points can be added to the change vector set, and according to the reference points corresponding to the vectors in the change vector set, it can be determined which sea reference point has deviated. Generally, if a sea reference point has deviated, the current relative position vectors of the sea reference point and all other reference points are different from the reference relative position vectors. Therefore, if the current relative position vectors of the sea reference point 101 and all other reference points are in the change vector set, it is determined that the sea reference point 101 has deviated. In this way, the sea reference point that has deviated can be accurately detected. Figure 5

[0052] With reference still to Figure 3 , in step S330, the position of the to-be-calibrated reference point is calibrated according to the first calibration data of the to-be-calibrated reference point.

[0053] For example, if the to-be-calibrated reference point includes the sea reference point 101, and other reference points have not deviated, the current position of the sea reference point 101 can be calculated according to the current relative position vectors between the sea reference point 101 and other reference points, that is, the calibrated position is obtained. Subsequently, the calibrated position of the reference point can be used to monitor the sea photovoltaic unit.

[0054] In an embodiment, the first calibration data of the to-be-calibrated reference point includes the current relative position vectors between the to-be-calibrated reference point and other reference points. As shown in Figure 6 , the above calibration of the position of the to-be-calibrated reference point according to the first calibration data of the to-be-calibrated reference point includes the following steps S610 and S620:

[0055] Step S610, determining a plurality of first positions of the to-be-calibrated reference point according to the current relative position vectors between the to-be-calibrated reference point and other reference points;

[0056] Step S620, determining the calibrated position of the to-be-calibrated reference point according to the plurality of first positions.

[0057] The first position is a position calculated according to a single reference point. For example, if the to-be-calibrated reference point includes the sea reference point 101, the first position of the sea reference point 101 with the sea reference point 102 as the reference can be calculated according to the current relative position vectors between the sea reference point 101 and the sea reference point 102, and is denoted as the first position Q 12 . Similarly, the first position of the sea reference point 101 with the sea reference point 103 as the reference can be calculated according to the current relative position vectors between the sea reference point 101 and the sea reference point 103, and is denoted as Q 13 ​According to the current relative position vector between the sea reference point 101 and the land reference point 104, the first position of the sea reference point 101 based on the land reference point 104 is calculated and recorded as Q 14 According to the current relative position vector between the sea reference point 101 and the land reference point 105, the first position of the sea reference point 101 based on the land reference point 105 is calculated and recorded as Q 15 .

[0058] There may be differences between the multiple first positions. Clustering, statistics, etc. can be used to fuse the multiple first positions to obtain the calibrated position of the reference point to be calibrated.

[0059] In one embodiment, the method of determining the calibrated position of the reference point to be calibrated based on the multiple first positions includes the following steps:

[0060] determining a dynamic weight of each other reference point based on the distance between each other reference point and the reference point to be calibrated;

[0061] Determine the target weight of each other benchmark point based on its dynamic weight and basic weight; the basic weight of the land benchmark point is greater than the basic weight of the sea benchmark point;

[0062] The plurality of first positions are weighted according to the target weight of each other reference point to obtain a calibrated position of the reference point to be calibrated.

[0063] The dynamic weight is determined by distance (e.g., calculated from the current relative position vector or determined in the previous cycle). The greater the distance, the smaller the dynamic weight. The base weight is determined by the land or sea type of the benchmark. Both land and sea benchmarks can have fixed base weights. Due to their greater stability, land benchmarks have larger base weights than sea benchmarks. The dynamic weight and base weight can be added, multiplied, or other algorithms can be used to obtain the target weight. The multiple first positions are weighted according to the target weight of each additional benchmark to obtain the calibrated position of the benchmark to be calibrated.

[0064] For example, according to P 12 Determine the distance between the offshore reference point 101 and the offshore reference point 102 as L 12 , and then calculate the dynamic weight W of the offshore reference point 102 dis12 =1 / L 12 α , α is the distance weight index, which is used to adjust the relationship between the dynamic weight and the distance. It can be set according to experience or specific business needs, such as a value in the range of (0,1). Similarly, the dynamic weight W of the offshore reference point 103 can be obtained. dis13 =1 / L 13α , the dynamic weight W of the land reference point 104 dis14 =1 / L 14 α , the dynamic weight W of the land reference point 105 dis15 =1 / L 15 α . The basic weight W of the land reference point is obtained land , the basic weight W of the sea reference point sea The two basic weight values can be set according to experience or specific business requirements, and are usually fixed values. The target weight W of the sea reference point 102 is calculated as 12 =norm(W dis12 ×W sea ), norm represents normalization; similarly, the target weight W of the sea reference point 103 is 13 =norm(W dis13 ×W sea ), the target weight W of the land reference point 104 is 14 =norm(W dis14 ×W land ), the target weight W of the land reference point 105 is 15 =norm(W dis15 ×W land ). Finally, the calibrated position of the sea reference point 101 is calculated as: Q cal1 =W 12 ×Q 12 +W 13 ×Q 13 +W 14 ×Q 14 +W 15 ×Q 15 . Thus, the calibration process of the sea reference point 101 is realized. In this way, the calibration results of multiple reference points are fused, which has higher accuracy.

[0065] The exemplary embodiments of the present disclosure also provide a reference point calibration device for offshore photovoltaic, which is applied to a reference point network system including multiple reference points, the multiple reference points including at least two sea reference points and at least two land reference points.
