[0002] The digital homework automatic grading system in the prior art relies on laying dot matrix codes in the answer area in advance. Students use dot matrix pens to fill in the answers on the answer sheet according to the test paper or teaching aids. After the students finish filling, they use the student client to connect the dot matrix pen and upload the track information stored in the dot matrix pen to the student client. The student client identifies the track information, analyzes the answer sheet ID filled in by the student, and uploads it to the grading server together with the student's identity information. The grading server identifies them separately. For non-subjective questions, the identification results are compared with the standard answers pre-entered by the teacher. For subjective questions, the teacher needs to use the dot matrix pen to connect to the teacher client for online grading.

[0003] When printing the documents required for digital correction using ordinary printing methods, the text and pictures in the documents contain carbon, which can easily interfere with the dot matrix code recognition of the dot matrix pen, resulting in handwriting disconnection, two strokes connected into one stroke, etc. when the handwriting is restored, and the recognition success rate is low.

[0036] The present invention will be described in detail below in conjunction with the specific embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any structural, methodological, or functional changes made by a person skilled in the art based on these embodiments are all within the scope of protection of the present invention.

[0037] The terms used in the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention. The singular forms "a", "the" and "the" used in the present invention and the appended claims are also intended to include plural forms unless the context clearly indicates other meanings. It should also be understood that the term "and / or" used herein refers to and includes any or all possible combinations of one or more associated listed items.

[0038] like Figure 1 As shown, a digital homework correction method for improving document printing includes the following steps:

[0039] Step S101, obtaining a test paper that has been processed with dot matrix coding, wherein the test paper is issued from a teacher terminal to each student terminal, and the test paper includes a question area and a coding area.

[0040] The teacher's terminal logs in to the teaching software system to publish homework, and can select several test questions from the question bank to form a test paper or manually input the test questions to form a test paper. The students who receive the test paper are several classes or several students associated with the teacher's account.

[0041] The test paper processed by dot matrix coding means that the question area of ​​the test paper includes a plurality of questions, and each question is followed by a coding area consisting of a plurality of small codes corresponding to the question. The small code is associated with at least one of the following information: school, class, student name, subject, question number, question ID, question type, score of the question, full score of the question, and grading time.

[0042] The coding area can be set in front of the question area or behind the question area. Each coding area can have multiple small codes corresponding to different scores, which is suitable for teachers to correct in one of the small code areas. For example, the full score of question 1 is set to 8 points, and the coding area of ​​question 1 can be set with 8 small codes corresponding to scores of 1 point to 8 points. The student should get 5 points for answering the question, and the teacher only needs to correct in the small code area corresponding to the score of 5 points.

[0043] Step S102, obtaining the test paper sent back from the student terminal.

[0044] After the students answer the test papers, the answered test papers are uploaded to the server through the student terminals.

[0045] Step S103, printing the test paper, wherein the question area of ​​the test paper is printed without carbon, and the code area is printed with carbon.

[0046] One embodiment of the present application is to print out the test paper by a color printing machine, wherein the question area of ​​the test paper is printed with non-carbon ink, and the code area is printed with carbon-containing ink.

[0047] Carbon inks are mainly composed of fine carbon powder, pigments, solvents and stabilizers. Carbon inks usually appear black or gray and are often used in writing, painting and printing. Non-carbon inks can present different colors depending on the type of pigment or dye used. They have richer color options and are often used in printing photos, paintings and artworks that require multiple colors.

[0048] The present invention can use a color printing machine that prints with ink, and the printing method is ink printing or inkjet printing. For example, the three CMY ink channels of the color printing machine can be cleaned and then filled with non-carbon ink without carbon, and the K channel uses black ink containing carbon, and other accessories of the color printing machine do not need to be processed. Among them, the font color of the question area of ​​the test paper can be set to pure red or pure yellow before printing to enhance the distinction.

[0049] Another embodiment of the present application is to print out the test paper through a laser printer, wherein a PS driver package and a driver matching list are configured, and the K value of the CMYK color mode of the laser printer is adjusted based on the PS driver package and the driver matching list to achieve the layering of the question area and the coding area of ​​the test paper, the K value is zero when printing the question area of ​​the test paper, and the K value is not zero when printing the coding area.

[0050] Here, the PS driver package and driver matching list are configured and selected and set according to the actual needs of printing requirements. After the print settings are made on the adobe printing software, the test paper is printed out through a laser printer. The printing requirement of this application is that the K value is zero when printing the question area of ​​the test paper, and the K value is not zero when printing the coding area.

[0051] The CMYK color mode of a laser printer is a standard color mode that mixes four colors of the full color system, namely C-cyan, M-magenta, Y-yellow and K-black. When the K value is zero, the carbon content is zero. At this time, the text in the title area of ​​the printed test paper does not contain carbon. Conversely, when the K value is not zero, the small code in the coding area will contain carbon.

[0052] You can use the Adobe printing software to check whether the printed file contains carbon. Through the print output preview of the printing program, only check black in the output color option. If there is black text at the bottom of the print preview, it means that it contains carbon. If there is no black text at the bottom of the print preview, it means that K is 0 and it does not contain carbon.

[0053] Step S104, obtaining the content written by the teacher in the coding area using the dot matrix pen.

[0054] The dot matrix pen includes a Bluetooth or USB communication unit, a battery, a memory, a processor, a high-definition camera and a pressure sensor, wherein the Bluetooth or USB communication unit is responsible for communication, sending the information in the dot matrix pen to other devices, the battery is responsible for power supply, the memory is responsible for temporarily storing the information obtained by the dot matrix pen, such as page coordinates, shooting time, page number, pressure size, etc., the processor is responsible for decoding the dot matrix number, the high-definition camera is responsible for continuously scanning the dot matrix code in the coding area, and the pressure sensor is responsible for obtaining pressure data. When teachers use the dot matrix pen to mark test papers, they do not need to erase the entire small code, but only need to write in part of the small code area to complete the marking of the test paper.

[0055] The teacher uses a dot pen to write on the small code behind the question. The high-speed camera at the front end of the dot pen can capture the movement trajectory of the pen tip at any time. At the same time, the pressure sensor transmits the pressure data back to the processor. After receiving the pressure data returned by the dot pen, the processor confirms the score of the small code.

[0056] Step S105, identifying the content written by the teacher in the coding area, and determining the score of the test paper according to the preset scoring rules.

[0057] Because each small code is associated with the corresponding question number, question ID, question type and question score, the score of each question can be determined by restoring and recognizing the teacher's dot matrix code handwriting, and the score of the test paper can be summarized.

[0058] The scoring rules may include: a point addition mode and a point reduction mode;

[0059] In the scoring mode, the score of the question is: the score corresponding to the written small code;

[0060] In the deduction mode, the score of the question is: the total score of the question minus the score corresponding to the written small code.

[0061] Since the teacher only needs to write on a small code in the coding area corresponding to each question area, and then the processor obtains the pressure data to confirm the score corresponding to the small code to determine the score of the question, the score of the test paper is calculated cumulatively through the addition mode and subtraction mode. The entire process does not require judgment and recognition of the teacher's actual writing content, which can significantly reduce the engineering processing calculation amount of image recognition, thereby effectively improving the teacher's marking efficiency.

[0062] Corresponding to the above-mentioned embodiment of a digital job correction method for improving document printing, the present invention provides a digital job correction device for improving document printing, such as Figure 2 As shown, the device comprises:

[0063] The test paper coding module 201 is used to obtain the test paper after the dot matrix coding process, the test paper is issued by the teacher terminal to each student terminal, and the test paper includes a question area and a coding area;
