[0067] By adopting the above technical solution, the beneficial effects of the present invention are as follows:

[0068] 1. In controlling the negative spacing of shingled photovoltaic cells, this invention automatically monitors the negative spacing by acquiring images of the stepped surfaces at the beginning and end of the photovoltaic cells. This accurately monitors the deviation between the actual spacing and the design value, improving the precision of the negative spacing control. Furthermore, by periodically monitoring the power generation of the photovoltaic cells, the invention uses the periodic power generation monitoring results combined with the negative spacing deviation monitoring index value to automatically control and warn of the photovoltaic cells. This improves the timeliness of photovoltaic cell process adjustments, enabling timely and targeted process adjustments to the photovoltaic cells, further enhancing the power generation efficiency of the photovoltaic cells.

[0069] 2. In this invention, negative spacing values ​​are obtained by image negative spacing monitoring and shingled negative spacing analysis is performed. Non-contact geometric measurement is used to replace traditional manual caliper detection, avoiding the risk of damage to the battery strip edge caused by physical contact. At the same time, the detection accuracy is greatly improved, ensuring accurate capture of negative spacing changes.

[0070] 3. In this invention, the existence of the negative spacing deviation monitoring index value is compared with the preset range of the negative spacing deviation index to determine whether the shingled spacing of the target photovoltaic cell is reasonable. This can quickly identify abnormal shingled spacing and reduce power generation efficiency loss caused by installation defects from the source. By conducting targeted periodic power generation monitoring on photovoltaic cells with reasonable shingled spacing, performance degradation trends can be actively captured, and preventive maintenance can be achieved through data-driven approaches to avoid sudden failures. This hierarchical management and control strategy not only ensures basic quality standards but also extends the effective service life of equipment through continuous performance tracking, ultimately improving the overall operation and maintenance efficiency and power generation revenue of photovoltaic cells. Therefore, this invention achieves dual optimization of photovoltaic cell quality and performance through a collaborative mechanism of dynamic comparison and intelligent monitoring.

[0089] Specifically as follows:

[0090] S131, reference Figure 2As shown, in the target photovoltaic cell, the first stepped surface formed by stacking photovoltaic cells D1 to Da with negative spacing is obtained to obtain the first shingled monitoring plane, and the second stepped surface formed by stacking photovoltaic cells D1 to Da with negative spacing is obtained to obtain the second shingled monitoring plane.

[0091] S132. Images of the first shingle monitoring plane and the second shingle monitoring plane are acquired respectively to obtain images of the first shingle plane and the second shingle plane.

[0092] In this embodiment, the first shingled planar image and the second shingled planar image are obtained in the same way, and the display parameters of the D1 photovoltaic cell strip to the Da photovoltaic cell strip are the same in the first shingled planar image and the second shingled planar image. The display parameters involved here include, but are not limited to, display angle, display ratio and distortion angle.

[0093] S133. Perform negative spacing monitoring on photovoltaic cell strips D1 to Da in the first shingled planar image, and obtain the negative spacing values ​​from the beginning of D1 to the beginning of Db based on the monitoring results.

[0094] In this embodiment, the two photovoltaic cell strips will show a negative spacing between the shingled layers in the shingled image, so b = a - 1.

[0095] Step S133 is as follows:

[0096] S1331, please refer to Figure 3 The first head shingle feature point P1 is obtained by acquiring the right edge point of the D1 photovoltaic cell strip in the first shingle planar image. The second head shingle feature point P2 is obtained by acquiring the left edge point of the D2 photovoltaic cell strip in the first shingle planar image. The third head shingle feature point P3 is obtained by acquiring the right edge point of the D2 photovoltaic cell strip in the first shingle planar image. And so on, the cth head shingle feature point Pc is obtained by acquiring the left edge point of the Da photovoltaic cell strip in the first shingle planar image.

[0097] Here, c represents the number of feature points corresponding to the first shingled tile, and c is an integer greater than 0.

[0098] S1332. In the first shingled planar image, extend the upper edge line of the D1 photovoltaic cell strip to obtain the first reference line L. Draw a perpendicular line from the first first shingled feature point P1 to the first reference line L to obtain the first shingled feature line L1. Draw a perpendicular line from the second first shingled feature point P2 to the first reference line L to obtain the second shingled feature line L2. And so on, draw a perpendicular line from the cth first shingled feature point Pc to the first reference line L to obtain the cth shingled feature line Lc.

[0099] S1333. The vertical distance between the first shingle head feature line L1 and the second shingle head feature line L2 is numerically obtained to obtain the head negative spacing value D1. The vertical distance between the third shingle head feature line L3 and the fourth shingle head feature line L4 is numerically obtained to obtain the head negative spacing value D2. And so on, the vertical distance between the (c-1)th shingle head feature line Lc-1 and the cth shingle head feature line Lc is numerically obtained to obtain the head negative spacing value Db.

[0100] S134. Perform negative spacing monitoring on photovoltaic cell strips D1 to Da in the second shingled planar image, and obtain the negative spacing values ​​from the tail of D1 to the tail of Db based on the monitoring results.

[0101] Specifically as follows:

[0102] S1341, please refer to Figure 4 The first tail shingled feature point Q1 is obtained by acquiring the right edge point of the D1 photovoltaic cell strip in the second shingled plane image. The second tail shingled feature point Q2 is obtained by acquiring the left edge point of the D2 photovoltaic cell strip in the second shingled plane image. The third tail shingled feature point Q3 is obtained by acquiring the right edge point of the D2 photovoltaic cell strip in the second shingled plane image. Similarly, the c-th tail shingled feature point Qc is obtained by acquiring the left edge point of the Da photovoltaic cell strip in the second shingled plane image.

Draw a perpendicular line from the tail reference line F through the first tail shingled feature point Q1 to obtain the first tail feature line F1. Draw a perpendicular line from the tail reference line F through the second tail shingled feature point Q2 to obtain the second tail feature line F2. And so on, draw a perpendicular line from the tail reference line F through the c-th tail shingled feature point Qc to obtain the c-th tail feature line Fc.

The vertical distance between the tail feature line F1 of the first shingle and the tail feature line F2 of the second shingle is numerically obtained to obtain the tail negative distance value D1. The vertical distance between the tail feature line F3 of the third shingle and the tail feature line F4 of the fourth shingle is numerically obtained to obtain the tail negative distance value D2. Similarly, the vertical distance between the tail feature line Fc-1 of the (c-1)th shingle and the tail feature line Fc of the cth shingle is numerically obtained to obtain the tail negative distance value Db.

[0105] S135. Obtain the negative spacing deviation monitoring index value based on the negative spacing value from the beginning of D1 to the beginning of Db and the negative spacing value from the end of D1 to the end of Db.

[0106] Specifically as follows:

Obtain the reference value of the shingled negative spacing corresponding to the set target photovoltaic cell, calculate the difference between the negative spacing value at the beginning of D1 and the reference value of the shingled negative spacing, and take the absolute value of the obtained difference to obtain the negative spacing deviation value at the beginning of D1. Calculate the difference between the negative spacing value at the end of D1 and the reference value of the shingled negative spacing, and take the absolute value of the obtained difference to obtain the negative spacing deviation value at the end of D1.

[0108] The shingled negative spacing reference value mentioned here is specifically the shingled negative spacing value determined during the design of the target photovoltaic cell, which is generally 1~3mm, and preferably 3mm in this embodiment.

[0109] The negative spacing deviation value at the beginning of D1 is compared with the negative spacing deviation value at the end of D1. If the negative spacing deviation value at the beginning of D1 is greater than or equal to the negative spacing deviation value at the end of D1, then the negative spacing deviation value at the beginning of D1 is set as the negative spacing deviation value between the photovoltaic cell strip D1 and the photovoltaic cell strip D2.

[0110] The negative spacing deviation value at the head of D1 is compared with the negative spacing deviation value at the tail of D1. If the negative spacing deviation value at the head of D1 is less than the negative spacing deviation value at the tail of D1, then the negative spacing deviation value at the tail of D1 is set as the negative spacing deviation value between the photovoltaic cell strips D1 and D2.

[0111] Repeat the process of obtaining the negative spacing deviation value between photovoltaic cell strips D1 and D2, and obtain the negative spacing deviation value between every two consecutive photovoltaic cell strips to obtain multiple negative spacing deviation values.

The average negative spacing deviation of the photovoltaic cells corresponding to each historical photovoltaic cell was obtained. The values ​​of the obtained average negative spacing deviations of photovoltaic cells were compared. The average negative spacing deviation of the photovoltaic cells with the smallest value was set as the lower limit of the reasonable range of negative spacing deviation, and the average negative spacing deviation of the photovoltaic cells with the largest value was set as the upper limit of the reasonable range of negative spacing deviation, thus obtaining the reasonable range of negative spacing deviation. The difference between the maximum value of the average negative spacing deviation of photovoltaic cells corresponding to the upper limit of the reasonable range of negative spacing deviation and the minimum value of the average negative spacing deviation of photovoltaic cells corresponding to the lower limit of the reasonable range of negative spacing deviation was calculated to obtain the span of the reasonable range of deviation.

[0115] The historical photovoltaic cells involved here are the same type as the target photovoltaic cells.

[0116] S1353. Statistically count the negative spacing deviation values ​​within the reasonable range of negative spacing deviation to obtain the reasonable spacing deviation value. Statistically count the negative spacing deviation values ​​to obtain the negative spacing deviation value. Calculate the ratio of the reasonable spacing deviation value to the negative spacing deviation value to obtain the negative spacing deviation pass rate.

[0117] Among them, the range within the reasonable deviation range includes the case where it is within the range.

[0118] S1354. The negative spacing deviation monitoring index value is calculated based on the negative spacing deviation compliance rate, the reasonable range of deviation, and multiple negative spacing deviation values; the specific calculation formula is as follows:

[0119]

[0120] Wherein, Pzb is the negative spacing deviation monitoring index value, Hgd is the negative spacing deviation qualification rate, Hfz is the reasonable range of deviation, Fpci is any one of the multiple negative spacing deviation values, and n is the quantity value corresponding to the negative spacing deviation value.

[0121] In this embodiment, step S1 adopts the above-mentioned technical solution, which uses a geometric method to monitor the negative spacing of photovoltaic cell strips D1 to Da in the first shingled plan view and the second shingled plan view. Based on the monitoring results, the negative spacing values ​​from the tail of D1 to the tail of Db and from the tail of D1 to the tail of Db are obtained. Based on this, a comprehensive shingled negative spacing analysis is performed on the target photovoltaic cell. This method uses non-contact geometric measurement to replace traditional manual caliper detection, which can effectively avoid edge damage to the cell strips caused by physical contact, and at the same time improve the detection accuracy to the micrometer level, ensuring accurate capture of negative spacing changes.

[0122] S2. Based on the negative spacing deviation monitoring index value, determine the spacing rationality of the target photovoltaic cells, monitor the photovoltaic power generation of the target photovoltaic cells based on the judgment result, and obtain the cell power monitoring data based on the monitoring result.

[0123] Specifically as follows:

[0124] S21. Obtain the preset range of the negative spacing deviation index, and judge the rationality of the shingle spacing based on the negative spacing deviation monitoring index value and the preset range of the negative spacing deviation index:

[0125] If the negative spacing deviation monitoring index value is within the preset range of the negative spacing deviation index, it is determined that the shingled spacing corresponding to the target photovoltaic cell is reasonable. If the negative spacing deviation monitoring index value is not within the preset range of the negative spacing deviation index, it is determined that the shingled spacing corresponding to the target photovoltaic cell is unreasonable. The reasonableness judgment data of the shingled spacing is obtained.

[0126] Reasonable shingle spacing includes situations where the negative spacing deviation monitoring index value is within the preset range boundary of the negative spacing deviation index.

[0127] Specifically, the preset range for obtaining the negative spacing deviation index is as follows:

[0128] Obtain several historical photovoltaic cells with reasonable shingled spacing. For each historical photovoltaic cell, obtain its corresponding negative spacing deviation monitoring index value according to the method in step S1. Compare the numerical values ​​of several negative spacing deviation monitoring index values ​​of the obtained historical photovoltaic cells. Set the negative spacing deviation monitoring index value with the smallest value as the lower limit of the preset range of negative spacing deviation index, and set the preset range of negative spacing deviation index with the largest value as the upper limit of the reasonable range of negative spacing deviation, thus obtaining the preset range of negative spacing deviation index.

[0129] S22. If the shingled spacing of the target photovoltaic cell is reasonable, the power generation of the target photovoltaic cell is monitored, and periodic power generation monitoring data is obtained based on the monitoring results, thereby obtaining the cell power monitoring data.

[0130] Specifically as follows:

[0131] Obtain the set power generation monitoring period, obtain the average power generation of the target photovoltaic cell within the power generation monitoring period, and obtain the target period power generation.

[0132] In the process of monitoring the power generation of the target photovoltaic cell, the time point at which the target photovoltaic cell begins to generate electricity can be set as the first power generation characteristic time point, and the time point corresponding to the monitoring time can be set as the second power generation characteristic time point. Alternatively, other specific times after the start of power generation can be selected as the second power generation characteristic time point, and the time period between the first power generation characteristic time point and the second power generation characteristic time point can be set as the power generation monitoring period. Preferably, the power generation monitoring period is set to 60 seconds.

[0133] The photovoltaic cells already in operation at the photovoltaic power station were obtained, resulting in multiple photovoltaic cells in operation.

[0134] In this embodiment, all photovoltaic cells involved in production are photovoltaic cells with normal power generation, and the photovoltaic cells involved in production are of the same type as the target photovoltaic cells.

[0135] The average power generation of each photovoltaic cell in operation during the power generation monitoring period is obtained to obtain multiple power generation values. The values ​​of these multiple power generation values ​​are compared, and the power generation value with the largest value is set as the upper limit of the reasonable power generation range, while the power generation value with the smallest value is set as the lower limit of the reasonable power generation range, thus obtaining the reasonable power generation range.

[0136] The reasonable range of power generation and the target periodic power generation are defined as periodic power generation monitoring data, and the periodic power generation monitoring data and the data for judging the reasonableness of the shingled spacing are defined as cell power monitoring data.

[0137] In this embodiment, step S2 adopts the above-mentioned scheme, which determines whether the shingled spacing of the target photovoltaic cell is reasonable by comparing the negative spacing deviation monitoring index value with the preset range of the negative spacing deviation index. Then, targeted periodic power generation monitoring is performed on photovoltaic cells with reasonable shingled spacing. In this way, through the synergistic mechanism of dynamic comparison and intelligent monitoring, the dual optimization of photovoltaic cell quality and performance is achieved.

[0138] First, the preset interval comparison can quickly identify abnormal shingle spacing, reducing the loss of power generation efficiency caused by installation defects from the source;

[0139] Secondly, periodic power generation monitoring of qualified products can proactively capture performance degradation trends, enabling preventative maintenance through data-driven approaches and avoiding sudden failures.

[0140] Finally, this tiered management strategy not only ensures basic quality standards but also extends the effective service life of equipment through continuous performance tracking, ultimately improving overall operation and maintenance efficiency and power generation revenue.

[0141] S3. Conduct photovoltaic control early warning for the target photovoltaic cells based on the cell power monitoring data.

[0142] Specifically as follows:

[0143] Acquire solar cell power monitoring data; based on this data, obtain periodic power generation monitoring data and shingle spacing rationality assessment data; based on these data, determine whether to issue a photovoltaic control early warning, specifically:

[0144] If the data on the rationality of the shingle spacing shows that the shingle spacing corresponding to the target photovoltaic cell is unreasonable, a photovoltaic control warning will be issued directly.

[0145] If the data from the shingle spacing assessment shows that the shingle spacing corresponding to the target photovoltaic cells is reasonable, then further judgment is made based on the reasonable power generation range and the target cycle power generation obtained from the cell power monitoring data:

[0146] If the power generation during the target period is within a reasonable range, there is no need to issue a photovoltaic control warning.

[0147] If the target period's power generation is not within a reasonable range, a photovoltaic control early warning will be issued directly.

[0148] Among them, situations in which photovoltaic control early warnings are issued directly include when the target period power generation is not within the reasonable power generation range boundary.

[0149] It should be noted that in the above process of this embodiment, if a corresponding calculation formula appears, the above calculation formula is to remove the dimension and take its numerical value. The weight coefficient, proportional coefficient and other coefficients in the formula are set to a result value obtained by quantifying each parameter. The size of the weight coefficient and proportional coefficient is only necessary to not affect the proportional relationship between the parameter and the result value.

Based on the first shingled plane image and the second shingled plane image, the negative spacing deviation of the target photovoltaic cell is analyzed, and the negative spacing deviation monitoring index value is obtained based on the analysis results.

[0152] The power monitoring module is used to judge the spacing rationality of the target photovoltaic cells based on the negative spacing deviation monitoring index value, monitor the photovoltaic power generation of the target photovoltaic cells based on the judgment result, and obtain the cell power monitoring data based on the monitoring result.
