The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, but not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

As shown in FIG. 1, it is a structural diagram of a homework arrangement and correction system provided by an embodiment of the present invention. The system includes: a teacher terminal 101, a cloud server 102, a printing terminal 103, and a smart pen 104, wherein:

The teacher terminal 101 uses the teacher account to generate an assignment file, selects a set of students to receive assignments, and uploads the assignment file and the set of students who receive assignments to the cloud server 102 .

Specifically, the teacher terminal 101 selects a number of test questions from the question bank to form an assignment file or manually edit the assignment content to form an assignment file. Among them, the methods of grouping papers through the question bank include manual grouping and automatic grouping. Manual grouping is to manually select test questions by entering the corresponding test question bank according to the knowledge points of the chapters, and then grouping the selected test questions; automatic grouping is: Set the question type and difficulty level according to the chapter knowledge points, and the system will automatically select the test questions. Optionally, the automatic test composition can also use intelligent analysis software to analyze the students' historical answering situation, find out the weak links of the students, and select relevant test questions for test composition. In this case, the assignment files corresponding to each student may be different. After the test set is completed, the teacher terminal selects the set of students who want to receive the homework, uploads the homework file to the cloud server, and at the same time, generates a homework release message and sends it to each student terminal. The set of students who receive the homework file is a class or a set of several student accounts associated with the teacher's account.

The cloud server 102 performs scribing on the homework file to generate a stitching homework file, and sends the stitching homework file to the printing terminal 103 bound to each student account in the set of students receiving the homework for printing.

In the present invention, the cloud server 102 refers to a general term, which may be a comprehensive server integrating all functions, or a general term for multiple servers, such as a cloud disk server, a teaching background server, and the like.

The cloud server 102 obtains lattice resources from the lattice resource database, and performs lattice encoding on the job file to generate a lattice encoding job file. Specifically, the lattice resource is loaded above the job file, as shown in FIG. 2 , which is a schematic diagram of the job file encoded by the lattice resource. FIG. 3 is an enlarged schematic diagram of a certain part of the job file encoded by using the dot matrix resource. Lattice resources are composed of some very small dots arranged according to special algorithm rules. The function of the dot matrix is to provide a coordinate parameter information to the dot matrix identification device to ensure that the dot matrix identification device can accurately record the movement track when it moves in the dot matrix resource. Specifically, the dot matrix recognition device is a smart pen. The lattice resource is composed of several lattice units, and each lattice unit is composed of several dots. FIG. 4 is a schematic diagram of a lattice unit corresponding to the lattice resource provided by the embodiment of the present invention. The lattice unit includes a 4×4 virtual square, and each virtual square is composed of four grid points and one information point surrounded by the four grid points. Each dot matrix unit contains 16 information points. Each information point corresponds to eight different offset positions: upper, lower, left, right, upper left, lower left, and upper right. 16 points have 8 to the 16th power arrangement. , or 281 trillion permutations. Assuming that the distance between the virtual squares of each lattice unit is 0.5mm, the size of each lattice unit is 2mm×2mm. That is, the entire lattice resource can cover 281×400 million square meters. There are many ways of lattice encoding, and different lattice encoding methods correspond to different types of arrangements. For example, in the dot matrix coding scheme adopted by Anoto, each dot matrix unit contains 36 information points, and each information point contains 4 offset positions, totaling 47 trillion permutations.

As mentioned above, a lattice resource can be regarded as a huge piece of paper. Optionally, the lattice resources are allocated according to the user ID of the teacher's terminal, and the lattice resources in a certain code segment are allocated to a certain code segment. The teacher's user ID. The cloud server 102 obtains the corresponding dot matrix resource according to the user ID of the teacher terminal, and loads the dot matrix resource onto the homework file to generate a shop code homework file.

Optionally, an encoding rule is preset, and the encoding rule includes an encoding type and an encoding manner, and the encoding type includes single encoding and composite encoding; and the encoding manner includes full-page encoding and region encoding. Among them, single encoding uses one bitmap resource to encode the file, and compound encoding uses multiple bitmap resources to encode the file. Specifically, different bitmap resources carry different information and are loaded into different areas of the file. When the encoding mode is region encoding, it also includes the starting coordinates of the encoding region and the size of the encoding region.

Optionally, the dot matrix resource includes a first coding dot matrix resource and a second coding dot matrix resource, and loading the dot matrix resource onto the job file to generate a tiling job file includes:

Load the first encoding bitmap resource into the text area of the job file, load the second encoding bitmap resource into the additional information area of the job file, and generate the tiling job file. The user uses the dot matrix recognition device to click the additional information area to obtain the additional information of the job file, click the text area to obtain the coordinates written by the dot matrix recognition device there, and multiple coordinate information can form the writing track of the dot matrix recognition device. Wherein, the text area of the job file is an area that covers the content of the job file and/or needs to be written, and the additional information area of the job file is located on the cover of the job file or a surrounding area of the page that does not affect the display of the file content. FIG. 5 is a schematic diagram of a page of a lattice coded file encoded by using two kinds of lattice resources according to an embodiment of the present invention, and the additional information area thereof is located at the bottom of the page. It should be noted that the first encoding lattice resource carries the changed coordinate information. After the first encoding lattice resource is used to encode the text area of the job file, each position in the text area of the job file is laid with different lattices. information; the second encoding lattice resource carries fixed additional information, in order to ensure that the lattice identification device can accurately obtain the additional information carried by the second encoding resource when clicking on the additional information area, the basic information of the second encoding lattice resource is The coding unit is repeatedly laid in the additional information area of the job file.
