The method provided by the embodiment can be executed by the relevant server, and the server is taken as an example for explanation below.
As shown in fig. 1 to 3, a method for drawing a substation monitoring screen according to an embodiment of the present invention includes steps S11 to S14:
and S11, obtaining transformer substation information of the transformer substation to be monitored, and establishing an xml template library of the transformer substation to be monitored according to the transformer substation information. The xml template library comprises an equipment template library and a component template library.
It should be noted that, in order to solve the problem that the conventional professional drawing software such as CAD has a certain requirement on the industrial drawing capability, if a large drawing or a complex logical configuration is to be processed, a high-performance computer needs to be equipped and sufficient human input is ensured; other image identification methods aiming at design drawings or manufacturer drawings adopt computer vision technologies such as feature extraction and image identification, apply various machine learning algorithms to carry out image matching based on features, and have the problems of complex steps and poor scene adaptivity. The method comprises the steps of forming an electrical diagram svg file based on an xml template and a position adjusting strategy of basic equipment and components, constructing a substation monitoring user interface by adopting a front-end technology, identifying the ID attribute of the components led in the electrical diagram file, monitoring the change of real-time subscription data, and realizing the real-time display of closing, opening, alarming and networking data.
Specifically, taking the main wiring diagram as an example, the equipment template library may include one or more of an outgoing line, a high-voltage bus, a low-voltage bus, a bus PT, a main transformer, a current collection circuit, a grounding transformer, a station transformer and a reactive power compensation device; the component template library can comprise one or more of a breaker, a disconnecting switch, a grounding disconnecting switch and the like. The device template library and the component template library can independently form an electrical diagram svg file, and the file can be opened and viewed through a code editor, a browser or professional drawing software. It can be understood that, in other embodiments, the types of the devices or the components included in the device template library and the component template library respectively are further adjusted according to actual requirements.
And S12, performing image grid division on the monitoring picture of the transformer substation to be monitored according to the xml template library of the transformer substation to be monitored to obtain an image grid matrix.
Specifically, a monitoring picture of the transformer substation to be monitored is determined according to a transformer substation design file, a design drawing or a manufacturer supply drawing of the transformer substation to be monitored; dividing the monitoring picture according to image grids according to the xml template library of the transformer substation to be monitored to obtain an image grid matrix, and defining the image grid matrix as R (m, n); where m is the number of rows of the image grid and n is the maximum of the number of primitives of each row of the image grid. In addition, in this embodiment, the elements in the matrix may represent different devices by specific numbers, each row is filled from one element to the back according to the device, and the following elements are replaced by 0 when the maximum number of primitives is less than.
And S13, determining the position of each row of initial primitives and the position change logic of each row of primitives in the image grid matrix.
Specifically, the position of an initial primitive of each row in the image grid matrix is determined through a primitive position matrix, the primitive position matrix is defined as S (m, 2), and the transverse position and the longitudinal position of a first element of each row in the image grid matrix in xml are recorded. And determining the position change logic of each row of primitives in the image grid matrix through the primitive position logic matrix, and if the equipment of the primitives in the same row follows the same position change rule, defining the primitive position logic matrix as M (M, 2) to represent the transverse change step length and the longitudinal change step length of each row of positions. It can be understood that if the devices of the primitives in the same row do not follow the same position change rule, the rule can be further refined, and a plurality of matrices are defined to respectively describe the position change of each row.
And S14, identifying the component ID with the monitoring attribute in the xml template library, generating an electrical diagram according to the image grid matrix, the position of each row of initial primitives in the image grid matrix, the position change logic of each row of primitives and the component ID, and obtaining the monitoring picture of the transformer substation to be monitored according to the electrical diagram.
The device ID attribute is obtained by classifying monitoring attributes of devices with dynamic effect changes such as circuit breakers, disconnecting switches and grounding disconnecting switches in the template library, such as closing and opening, color changes of the devices and the like, and identifying the devices by adding prefixes or suffixes to the ID of the related measuring points.
Specifically, the attributes of all devices and/or components in the monitoring picture of the transformer substation to be monitored are set through loop iteration; and combining the xml templates of the independent devices and/or components to perform picture layout to form the electrical diagram. The electrical diagram comprises a main electrical diagram and a sub electrical diagram, the main electrical diagram can reflect the connection relation and the whole dynamic state between the equipment and the components, and the sub electrical diagram is used for reflecting the working states of the corresponding components or the equipment in real time.
Further, embedding the svg files of the main electrical diagram and the sub electrical diagram into a substation monitoring system of the substation to be monitored, and checking monitoring picture contents; and if the positions of the equipment and/or the components are not suitable, returning to the step of determining the position of each row of initial primitive and the position change logic of each row of primitive in the image grid matrix for fine adjustment until the picture layout meets the requirements.

For example, referring to fig. 2, the electrical diagram of the substation mainly includes a breaker (indicated by a rectangle), a bus (indicated by a horizontal line), and a general line (indicated by a vertical line). Note: this diagram is used as an example only, and the actual electrical diagram is more complex.

first, assuming that the resolution of the final monitoring screen is 1920 × 1080, the breaker diagram height H and width W are set to 80 and 40, respectively, the bus length L is 800, and the line length K is generally 80, and an xml template library is created.
Further, according to the xml template library of the transformer substation to be monitored, dividing the monitoring picture according to image grids to obtain an image grid matrix, defining a matrix R (m, n), wherein m is 11, and n is 16;
the number 1 represents a circuit breaker, the number 2 represents a bus, the number 3 represents a general line, then
Further, determining the position of each row of initial primitive in the image grid matrix through the primitive position matrix, and defining the primitive position matrix as S 1 (m, 2) record the horizontal and vertical positions of the primitive corresponding to the first element in each row of R (i.e., all elements in the first column of R). After the position of the first element in the first row is determined, the positions of other elements can be obtained according to some symmetrical relations, and the positions need to be simply planned in advance through sketch or drawing software.
Similarly, for the horizontal unknown and vertical positions of the primitives corresponding to all the elements in the ith column in R, S can be used i And (4) showing.
Further, determining the position change logic of each row of primitives in the image grid matrix through the primitive position logic matrix, defining a primitive position logic matrix M (M, 2) which represents the transverse change step length and the longitudinal change step length of each row of positions,
can be pushed out
S i ＝S i-1 +M
Furthermore, the measuring point IDs of all the circuit breakers are correlated, and in the subsequent step, the interface display can acquire real-time state data of the equipment through the attribute.
Then, according to S i ＝S i-1 A recurrence formula of + M, S can be determined i I =2, \8230n. is the position of all components in the electrical diagram, thereby combining the basic primitives in the xml template library to form the complete electrical diagram.
Further, according to the above steps, the following electrical diagram can be obtained, and it can be found that the positions of the 9 th to 16 th elements in the last two rows need to be adjusted, at this time, the step of determining the position change logic of each row of primitives in the image grid matrix can be returned, and the primitives needing to be adjusted are completed through the following recursion cycle.
S i ＝S 1 +(i-1)*M+N
And finally, subscribing the measuring point ID information associated with all the circuit breakers, and monitoring the change of the subscribed ID data to realize the real-time display of the equipment state, wherein the received subscribed numerical value is 1 to display a red closing state and the numerical value is 0 to display a green opening state, like the circuit breaker in the embodiment.
The method solves the problems of large workload and high professional requirements of the conventional software drawing; the automatic arrangement of the components of the monitoring picture of the transformer substation and the real-time state and data display of the monitoring picture of the transformer substation are realized, and the monitoring picture of the transformer substation can be organically fused with other monitoring pictures so as to construct large-scale power application and meet the requirements of practical application.
