Further, the view module in bureau further comprises: a three-dimensional image matrix conversion unit: the three-dimensional circuit board model drawing is used for obtaining a three-dimensional circuit board model drawing, determining a gray level image of each component through an RGB color space, determining a gray level value of each component according to the gray level image, and constructing a three-dimensional image matrix according to the gray level value; wherein,

component crawling unit: the device comparison is carried out according to the device set and a preset component library, whether unrecognized components exist or not is judged, and when the unrecognized components exist, component materials are crawled through a cloud network, and the component library is updated through the crawled components.
The view module in the office of the invention scans the model drawing of the circuit in a scanning way to create a sketch of the circuit board. However, although the method for creating a circuit board sketch has a technical prospect, the method is a scanning method, and is a three-dimensional circuit board model drawing designed based on the Altium software, so that the method is a data scanning method, the three-dimensional circuit board model drawing is identified after framing processing is performed during scanning, if the internal components of the three-dimensional circuit board model drawing are more, components are likely to be missed during scanning, or scanning is not accurate on a line, so that the specification of the created circuit board is possibly different from the components of the sketch on a scanning element; secondly, there is a problem that the circuit diagram is designed by scanning the component library, on the premise that the scanned circuit components exist in the component library. Otherwise, the circuit diagram obtained by scanning is likely to be incomplete due to the absence of components. Therefore, the invention sets a special executing mechanism for the view module in the bureau to solve the problems. In order to solve the above technical problems, the present invention adopts a matrix conversion method, in which each component has a gray value in an RGB color space, and the component is easier to mark in the color space, so as to generate a three-dimensional image matrix, and the specification mark is to mark each component according to its specification parameters, such as: rated current and rated voltage; the purpose of two-dimensional image conversion is that because the sketch generated finally in the invention is embodied in the form of a two-dimensional image, the two-dimensional conversion, the first point, can directly generate the two-dimensional image finally; the second point is that the parameter characteristics of each component are extracted through a plurality of two-dimensional images, and the parameter value of each component can be acquired more accurately based on the overlapping property. The dividing unit divides each component; this division is to cut each component into individual component pieces; the division also has the advantage that each component can be judged to be connected with other components during cutting, and because the cutting is based on the three-bit circuit diagram, the connection of each circuit diagram can be clearly determined, whether the connection is hidden connection or clearly displayed connection. The node netlist is formed by taking each device as a node in a table form, and devices connected with the node are marked, so that the situation that some connections are not generated when a circuit sketch is drawn is prevented. And finally, the component crawling unit is used for acquiring the component from the Internet through crawling of the component when the component does not have the same component in the component library, so that the component library can identify all the components as much as possible and can be automatically updated.
Preferably, the component crawling unit judges whether an unrecognized component exists or not, and includes the following steps:
step 1: according to a preset component library, constructing a contour function of the component according to the following formula:
L(k)＝δ(k)[βW(GW)2+βN(GN)2]
wherein,
l (k) represents a profile function of component k; δ (k) represents a convergence function of the contour coordinates of the component k; beta is aWRepresenting the outer contour of component k; beta is aW(GW)2Representing an outer contour boundary function of a component k; gWRepresenting an external profile curve function of the component k; i isw，i(xw，yw) An ith coordinate point representing an outer contour of the component k; x is the number ofwRepresenting an external lateral coordinate; y iswShowing external longitudinal coordinates; h (I (x)w，yw) A level set function representing the boundary of the outer contour of component k; beta is aNTo representThe internal profile of component k; beta is aN(GN)2Representing an internal contour boundary function of a component k; gNRepresenting an internal profile curve function of the component k; i isN，j(xN，yN) A j-th coordinate point representing an internal contour of the component k; x is the number ofNRepresenting an internal lateral coordinate; y isNShowing internal longitudinal coordinates; h (I (x)N，yN) A level set function representing the boundary of the internal contour of the component k; i represents a coordinate point of the external contour coordinate, i is a positive integer, and m external contour coordinates are total; j represents a coordinate point of the internal contour coordinate, j is a positive integer and has n internal contour coordinates;
in the step 1, the invention mainly constructs the contour function of the component through the component library, and in the process, the invention determines the contour function of the component in a mode of fusing the external contour and the internal contour. In this process, βW(GW)2Determining the outer contour boundary; and beta isN(GN)2The internal profile boundaries are determined because the circuit components, which may be externally identical, but internally profiled differently, for example: the circuit components with cavities have different parameters due to different thicknesses of component walls, which cause different sizes of the cavities. δ (k) is a convergence function whose purpose is to determine whether a coordinate point is a boundary coordinate point, which is a limit value. And in the calculation of the functions of the external contour and the internal contour, the invention mainly calculates the parameters finally obtained by the way of contour curves.
Step 2: according to a preset component library, constructing a parameter function of the component according to the following formula:
wherein C (k) represents a parameter function of component k; t (k) represents a type coefficient of a component k;
the parameter characteristic of the a type parameter of the q component is represented; gamma rayq，aA parameter value representing the a type parameter of the q component;
step 2 is mainly to calculate the parameter characteristics of the components, while the calculation of the parameters is relatively simpler, and the T (k) type coefficient determines what type of the components are, and the product of the parameter characteristics and the parameter values
Determines the characteristics of the component. The component identification of the invention judges whether the component exists in the component set mainly through two aspects of the outline and the characteristic, thereby ensuring that a circuit sketch generated after the circuit diagram is scanned has the same value as a scanned value regardless of the outline or the parameter, and ensuring the scanning accuracy.
And step 3: generating an identification model of the element library according to the parameter function of the element and the contour function of the element:
wherein S (C, L) is an identification model of the component library, and L (S) represents a contour function of the S-th component of the component set; c (S) represents the parameter function of the S component of the device set; f represents the total number of the components in the component library;
representing a recognition stimulus;
the identification model is established in a curve identification mode based on an exponential function, and the contour function and the parameter function of each component in the device set are taken to ensure that the same component is not in the component library in each device set.
