BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the drawings required for use in the embodiments or the description of the prior art will be briefly introduced below. Obviously, the drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, without paying creative labor, other drawings obtained based on these drawings still belong to the scope of the present invention.

[0034] Figure 2 A schematic diagram of the structure of a printer provided by an embodiment of the present invention. DETAILED DESCRIPTION

[0035] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings.

[0036] like Figure 1 As shown in the figure, a method for intelligently identifying power grid relay protection printing data information is provided in an embodiment of the present invention, which is used on a printer connected to a target power grid relay protection device. The method includes the following specific steps:

[0037] Step S1, receiving printing character data output by a target power grid relay protection device, wherein the printing character data is compiled from fixed value protection data generated by the target power grid relay protection device;

[0038] The specific process is that the fixed value protection data generated by the target power grid relay protection device is usually composed of binary 0 and 1. However, in order to reduce the length of the character data and facilitate storage and processing, the character data is converted from binary to a hexadecimal string.

[0039] At this time, during the printing process of the setting list, the target power grid relay protection device converts the setting protection data to be printed into printing character data, and sends it to the printer through the RS232 serial port in a one-way data transmission mode.

[0040] It should be noted that the fixed value protection data output by relay protection devices of different manufacturers, different models and different versions must be the same. For example, in the national standard, the corresponding code for the word "relay" is BC CC, the corresponding code for the word "electricity" is B5 E7, the corresponding code for the word "protection" is B1 A3, and the corresponding code for the word "protection" is BB A4. Therefore, the collected and saved BC CC B5 E7 B1 A3BB A4 will be identified as the four Chinese characters "relay protection". Similarly, in the national standard, it can be found that: phase: CFE0, interval: BCE4, distance: BEE0, distance: C0EB, III: A2F3, section: B6CE, fixed: B6A8, value: D6B5. Therefore, the collected and saved CF E0 BC E4 BE E0C0 EB A2 F3 B6 CE B6 A8 D6 B5 will be identified as "phase-to-phase distance III section fixed value".

[0041] Step S2, detecting whether the print character data carries a predetermined print line feed mark;

[0042] The specific process is that the printer pre-stores a predetermined print line feed mark, and can automatically identify its own maximum print width (that is, the maximum print character width value, which can be represented by the total number of characters) in advance, and identifies whether the print character data carries the predetermined print line feed mark by scanning each character one by one.

[0043] It should be noted that all printers equipped with relay protection devices use the ESC instruction set, and this instruction set complies with the national printer industry standards.

[0044] Step S3, in combination with a preset maximum print character width value, identifying the print character data that does not carry the predetermined print line feed mark line by line, and after adding or replacing the predetermined print line feed mark at the end of all identified lines, decompiling; or identifying the print character data that carries the predetermined print line feed mark line by line and directly decompiling;

[0045] The specific process is to check whether the print character data carries the predetermined print line feed mark, which is divided into the following three cases:

[0046] (1) The line break mark is not included and is empty:

[0047] If it is detected that the printing character data does not carry a predetermined printing line break mark, the printing character data is identified line by line with a preset maximum printing character width value as the basic length unit, and when it is determined that there are no other printing line break marks different from the predetermined printing line break mark at the end of all identified lines, the predetermined printing line break mark is added to the end of all identified lines, and the printing character data with the predetermined printing line break mark added is further decompiled to obtain the fixed value protection data generated by the target power grid relay protection device.

[0048] (2) Carrying other printing line break marks but not carrying the predetermined printing line break marks:

[0049] If it is detected that the printing character data does not carry a predetermined printing line break mark, the printing character data is identified line by line with a preset maximum printing character width value as the basic length unit, and when it is determined that there are any other printing line break marks different from the predetermined printing line break marks at the end of all identified lines, the printing line break marks at the end of all identified lines are replaced with the predetermined printing line break marks, and the printing character data replaced with the predetermined printing line break marks are further decompiled to obtain the fixed value protection data generated by the target power grid relay protection device.

[0050] (3) Carrying a predetermined printing line break mark:

[0051] If it is detected that the print character data already carries a predetermined print line break mark, the print character data is identified line by line and directly decompiled based on the preset maximum print character width value as the basic length unit.

[0052] Step S4, start printing, so that the fixed value protection data obtained by decompilation can be automatically printed in line breaks.

[0053] The specific process is that the decompiled fixed value protection data has a predetermined print line break mark, so that the printer can automatically print in line breaks, thereby intelligently identifying the print data information output by relay protection devices of different manufacturers to ensure that the print data is normal.

[0054] In one embodiment, all printers equipped with relay protection devices use the ESC instruction set, which is the industrial standard for printers. Taking the relay protection devices of the two companies "NARI" and "SIFANG" as examples, it is explained how the same printer can complete automatic printing recognition.

[0055] Output content: NSR-201RDN high voltage line protection device - protection setting

[0056] In the relay protection device of NARI, the results are:

[0057] B8 DF D1 B9 CF DF C2 B7 B1 A3 BB A4 D7 B0 D6 C3 A9 A5 A9 A5 A9 A5 B1A3 BB A4 B6 A8 D6 B5 0A 0D C3 A9 A5 A9

[0058] In the relay protection device of "Sifang" company, the results obtained are:

[0059] B8 DF D1 B9 CF DF C2 B7 B1 A3 BB A4 D7 B0 D6 C3 A9 A5 A9 A5 A9 A5 B1A3 BB A4 B6 A8 D6 B5

[0060] By comparison, it can be seen that the print data output by "Nanrui" company has an additional print line feed mark 0A 0D, but the print data output by "Sifang" company does not have the print line feed mark 0A 0D.

[0061] According to the analysis results, when the printer identification program processes the print data, if there is a predetermined print line feed mark 0A 0D, it is a product of "Nanrui" company and no further processing is required; if there is no 0A 0D, it is a product of "Sifang" company and the maximum print width judgment is required. When the maximum print width value is reached, the printer identification program needs to add the print line feed mark 0A 0D line by line in the print data to ensure correct line feed.

[0062] like Figure 2 As shown in the figure, a printer is provided in an embodiment of the present invention, including:

[0063] The receiving unit 110 is used to receive the printing character data output by the target power grid relay protection device, wherein the printing character data is compiled from the fixed value protection data generated by the target power grid relay protection device;

[0065] The compiling unit 130 is used to identify the printing character data that does not carry the predetermined printing line feed mark line by line in combination with the preset maximum printing character width value, and perform decompilation after the tails of all identified lines are added or replaced with the predetermined printing line feed mark; or identify the printing character data that carries the predetermined printing line feed mark line by line and directly perform decompilation;

[0066] The printing unit 140 is used to start printing so that the fixed value protection data obtained by decompilation can be automatically printed in line breaks.

[0067] The compiling unit 130 includes:

[0069] The compiling unit 130 further includes:

[0070] The second compilation module is used for, if it is detected that the printing character data does not carry the predetermined printing line feed identifier, identifying the printing character data line by line with the preset maximum printing character width value as the basic length unit, and when it is determined that there are any other printing line feed identifiers different from the predetermined printing line feed identifier at the end of all identified lines, replacing the printing line feed identifiers at the end of all identified lines with the predetermined printing line feed identifier, and further decompiling the printing character data replaced with the predetermined printing line feed identifier.

[0071] The compiling unit 130 further includes:

[0072] The third compiling module is used for, if it is detected that the printing character data already carries the predetermined printing line feed mark, identifying the printing character data line by line and directly decompiling it with the preset maximum printing character width value as the basic length unit.

[0073] Implementing the embodiments of the present invention has the following beneficial effects:

[0074] The present invention is based on the fact that different power grid relay protection devices output the same protection fixed value data, detects whether the printed character data after detection compilation carries a predetermined printing line feed mark, and adjusts the printed character data line by line in combination with the maximum printing character width value of the printer itself, so that the fixed value protection data obtained by decompilation can all be automatically printed in line feeds, thereby being able to intelligently identify the printed data information output by relay protection devices of different manufacturers to ensure that the printed data is normal.
