For example, after determining the phase to which each connecting piece belongs, comparing the ordinate of the 2 nd connecting piece with the ordinate of the 3 rd connecting piece, wherein the connecting piece with the smaller ordinate is placed at the 2 nd connecting piece, continuously comparing the ordinate of the 5 th connecting piece with the ordinate of the 6 th connecting piece, placing the connecting piece with the smaller ordinate at the 5 positions, and so on, so as to obtain the final permutation and combination of each connecting piece.
For example, the metering circuit in the image of the electric energy metering device may be as shown in fig. 4, where the metering circuit includes four phase connection pieces of a phase, B phase, C phase and N phase, each of the dashed boxes includes one phase-aligned connection piece, each of the phase a, B phase and C phase includes a voltage terminal connection piece, a current terminal upper end connection piece and a current terminal lower end connection piece, and positions of connection pieces of the same type in the phase a, B phase and C phase are the same. The N phase includes a voltage terminal connection pad.
In one embodiment, identifying whether the metering circuit is operating properly based on the coupling condition includes: comparing the connection state with a preset connection sheet connection state to obtain a comparison result; and identifying whether the metering loop works normally or not according to the comparison result.
The preset connection state of the connection sheets refers to the connection state of each connection sheet on the metering circuit which works normally.
After the terminal obtains the connection state of each connection tab, the connection state of each connection tab is compared with the connection state of the corresponding connection tab in the preset connection tab connection state, and when the comparison is consistent, the metering circuit is indicated to work normally. When the comparison is inconsistent, the metering loop cannot work normally, and the state of the metering loop is wrong.
For example, a schematic diagram of the metering circuit in normal operation may be as shown in fig. 4 above, wherein the voltage terminal connection pieces in the connection pieces of A, B, C, N four phases are all normally connected, the current upper end connection pieces are all normally connected, and the current lower end connection pieces are all disconnected.
In the embodiment, the connection state is compared with the preset connection sheet connection state, so that whether the metering loop works normally or not is identified, and the metering loop state can be accurately and rapidly judged.
In one embodiment, identifying whether the wiring mode of the metering circuit is faulty according to the position data of the metering circuit includes: intercepting a wire image in an electric energy metering device image according to the position data of the metering loop; respectively carrying out binarization processing on the wire images according to a preset wire color threshold value to obtain coordinates of the multiphase wires; sequencing the coordinates of the multiphase wires to obtain a wire color sequencing result; and comparing the wire color sequencing result with a preset wire color sequencing combination, and identifying whether the wiring mode of the metering loop is wrong.
The wire image refers to an image of a local area of all wires in the electric energy metering device. The preset wire color threshold value refers to a specific color threshold value set according to each phase wire color.
Specifically, the position data of the measuring circuit refers to a position frame of the measuring circuit, and the position frame includes coordinates of the measuring circuit. For example, the position box of the metering circuit may be expressed as:
wherein,,class_id'the metering loop is shown as such,left'the abscissa representing the upper left corner of the metering circuit,top'representing the ordinate of the upper left corner of the metering circuit,right'the abscissa representing the lower right hand corner of the metering circuit,bottom'indicating the ordinate of the lower right hand corner of the metering circuit,score'indicating the confidence in the type of metering loop. The terminal may intercept the wire image in the power metering device image according to the coordinates of the metering circuit.
And the corresponding phase conductor coordinates are obtained by calculating the outline of each phase conductor according to the color of each phase conductor and the outline of each phase conductor. For example, the color threshold of the a-phase wire is yellow, the color threshold of the B-phase wire is green, the color threshold of the C-phase wire is red, and the color threshold of the N-phase wire is black.
After the coordinates of the A, B, C, N four-phase wires are obtained, the wire color sorting result is obtained by sorting the coordinates of the A, B, C, N four-phase wires. The terminal stores a preset wire color sorting combination. For example, the number of the cells to be processed, the preset wire color ordering combinations are yellow, green red, red and black. Yellow represents the a-phase conductor, green represents the B-phase conductor, red represents the C-phase conductor, and black represents the N-phase conductor. And comparing the wire color sequencing result with a preset wire color sequencing combination, and if the wire colors are consistent in comparison, determining that the wiring mode of the metering loop is correct. If the color comparison of the wires is inconsistent, the wiring mode of the metering loop is wrong.
Illustratively, the truncated wire image may be as shown in fig. 5 (a), in which the 1 st to 3 rd wires are a-phase wires, the 4 th to 6 th wires are B-phase wires, the 7 th to 9 th wires are C-phase wires, and the 10 th wire is an N-phase wire. The binarization processing is performed on the wire images according to the preset wire color threshold value, and the obtained binarization images can be shown in fig. 5 (B), wherein the yellow binarization image is the binarization image of the A-phase wire, the green binarization image is the binarization image of the B-phase wire, the red binarization image is the binarization image of the C-phase wire, and the black binarization image is the binarization image of the N-phase wire.
Further, before the binarization processing is performed on the wire images according to the preset wire color threshold values, the method further includes: performing color gamut conversion on the wire image to obtain a converted image, and performing binarization processing on the converted image according to a preset wire color threshold value. For example, an opencv (open source computer vision library) may be used to convert a wire image from RGB color space to HSV space. The HSV image is obtained by performing color gamut conversion on the lead image so as to better perceive the color of the image, and the HSV component is utilized to extract the interested region from the image, so that the color recognition accuracy is improved.
In this embodiment, the wire image is intercepted in the image of the electric energy metering device according to the position data of the metering loop, and binarization processing is performed on the wire image according to the preset wire color threshold value, so as to obtain the coordinates of the multiphase wires, and the wire color and the wire coordinates can be accurately and rapidly identified. And the coordinates of the multiphase wires are sequenced, and the wire color sequencing result is compared with a preset wire color sequencing combination to identify whether the wiring mode of the metering loop is wrong. The checking efficiency and accuracy of the metering loop wiring mode are improved.
In an alternative manner of this embodiment, the preset wire color threshold includes a preset multi-phase wire color threshold; respectively carrying out binarization processing on the wire images according to preset wire color thresholds, and obtaining coordinates of the multiphase wires comprises the following steps: performing binarization processing on the wire image according to a preset color threshold value of each phase of wire to obtain the outline of each phase of wire; and determining the coordinates of the corresponding phase conductors according to the outlines of the phase conductors, and obtaining the coordinates of the multiphase conductors.
Performing binarization processing on the wire image according to a preset color threshold value of each phase wire to obtain the outline of each phase wire, obtaining the outline center point coordinate by obtaining the minimum circumscribed rectangle of the outline of each phase wire, and determining the outline center point coordinate as the coordinate of the wire with the corresponding color. Since the wire image includes A, B, C, N four-phase wires, the wire image needs to be subjected to image binarization with four different thresholds, so that the coordinates of the A, B, C, N four-phase wires can be obtained.
In this embodiment, the outline of each phase of wire can be obtained quickly by performing binarization processing on the wire image, and the coordinates of each phase of wire can be obtained accurately according to the outline of each phase of wire.
