Currently, screen printing text overlap is checked by manual measurement or by calling a measurement function carried by software. Manual inspection of screen printed text overlaps is time consuming and laborious and may be missed; measurement by calling a function of the software itself has a problem in that each screen printed text has an outer frame (the outer frame is not displayed on the screen printed layer, but actually exists), and the function is to judge whether the screen printed texts overlap or not by measuring the distance between the outer frames of the screen printed text. Fig. 1 shows a schematic diagram of the overlap between silk-screened text frames in the prior art. As shown in fig. 1, the two silk-screened texts "R345" and "C567" are not overlapped, but the outer frames where the "R345" and "C567" are located are overlapped, so that the overlapping result of the two silk-screened texts is obtained by the function measurement carried by software in the prior art.

checking whether single text shapes in the silk-screened text shapes overlap with single text shapes in other silk-screened text shapes;
and responding to the fact that the single text shapes in the silk-screened text shapes are not overlapped, and obtaining a result that the silk-screened texts are not overlapped.
2. The method as recited in claim 1, further comprising:
and responding to the superposition of the single text shape in the silk-screened text shape and the single text shape in other silk-screened text shapes, and receiving adjustment of the silk-screened text corresponding to the silk-screened text shape and/or the silk-screened text corresponding to the other silk-screened text shapes so as to ensure that the silk-screened text is not superposed with the other silk-screened text.
3. The method of claim 1, wherein checking whether a single text shape in a silk-screened text shape overlaps a single text shape in other silk-screened text shapes comprises:
each individual text shape in each of the silk-screened text shapes is checked in turn for overlap with individual text shapes in the other silk-screened text shapes.
4. The method of claim 1, wherein obtaining all screen printed text of a preset screen printed layer in the circuit board design drawing comprises:
and obtaining all silk-screen texts of the top silk-screen layer or the bottom silk-screen layer in the circuit board design drawing.
5. A system for inspecting the overlay of silk screened text, comprising:
the line segment conversion module is configured to acquire all screen printed texts of a preset screen printed layer in the circuit board design drawing, and convert each text element of each screen printed text into a plurality of line segments respectively through an axlText2Lines function and attribute the line segments to respective number columns so as to obtain a plurality of number columns corresponding to each screen printed text;
the combination module is configured to combine all line segments in each array into shapes of corresponding text elements through an axlPolyFromDB function to obtain single text shapes, and combine the single text shapes corresponding to the text elements in each silk-screened text into silk-screened text shapes through an axlPolyoperation function to obtain the silk-screened text shapes corresponding to all the silk-screened texts;
a checking module configured to check whether a single text shape in the silk-screened text shapes overlaps a single text shape in other silk-screened text shapes; and
and the result obtaining module is configured to respond to the fact that the single text shapes in the silk-screened text shapes are not overlapped, and obtain a result that the silk-screened text shapes are not overlapped.
6. A computer readable storage medium, characterized in that computer program instructions are stored, which when executed implement the method of any of claims 1-4.
7. A computer device comprising a memory and a processor, wherein the memory has stored therein a computer program which, when executed by the processor, performs the method of any of claims 1-4.
