Description
Technical Field
The invention relates to the technical field of Internet of things, in particular to an electronic system for a handwritten ticket.
Background
In recent years, in order to reduce the cost of storing, operating, and managing paper documents, a strong guide is being made by national policies, and the shift from paper documents to electronic documents is rapidly progressing. However, the paper ticket has the advantages of intuition, safety, demonstration and the like, so that the paper ticket can exist for a long time no matter how the electronization is developed. In order to efficiently utilize paper tickets and effectively transfer the paper tickets to electronization, the technology for developing electronization of paper documents and retaining paper medium documents becomes important.
At present, a petrochemical plant adopts an intelligent handheld terminal and the like to carry out electronic management on a safety operation certificate, so that the cost is high, a paper document cannot be stored while the electronic management is carried out, and in addition, the safety operation certificate possibly has danger or threat on an operation site such as a notebook computer or a tablet computer.
Aiming at the digitization of a handwritten ticket, a method and a device (a notice number CN 102156691A) for recording information of a manually filled paper form are invented by a patent right person, such as Zhaoyong and the like, and the method comprises the following steps: acquiring writing information of a user when filling in a paper form, and confirming each pixel information of a display area corresponding to the form according to the writing information; an electronic form obtaining step, namely obtaining a form type, and obtaining a blank electronic form of the form from a pre-established form database according to the form type; and a synthesizing step, synthesizing the blank electronic form and each pixel information of the display area corresponding to the form, thereby producing an electronic form copy corresponding to the paper form filled by the user.
Patent CN104820568A also discloses a data operation method, a smart pen, a data operation device, a terminal and a data operation system, wherein the data operation method includes: acquiring target data filled in a data filling area of a paper document by using an intelligent pen, and sending the target data to a terminal; identifying an operation gesture input by using an intelligent pen in a data operation area of the paper document; and generating an operation instruction according to the operation gesture so as to operate the target data, and sending the operation instruction to the terminal so that the terminal operates the target data according to the operation instruction. By the technical scheme, the content input by the user in the paper document can be synchronously input into the computer and other terminals, and the operation of the user on the content input in the paper document can be synchronously input into the terminals, so that the terminals and the intelligent pen complete synchronous operation, and the electronic document and the paper document are synchronously operated, so that the repeated operation of the user is avoided, and the operation efficiency of the paper document is improved.
The above two methods have problems in that:
the patent CN102156691A adopts the method that in the electronic form acquisition step, the form type needs to be confirmed according to the information input by the user; or shooting the form image, and comparing the form image with a pre-stored form template so as to determine the form type; or scanning the form barcode to confirm the form type;
in patent CN104820568A, although there is no description in the technical specification on how to "enable the terminal to store the target data carrying the current handwriting in the electronic document corresponding to the paper document", in the embodiment, "a computer screen displays the current electronic document to be filled by a first student, determines whether the paper document corresponding to the current electronic document is the document to be filled by the task, and if the determination result is yes, fills the paper document with an intelligent pen, and sends the filled contents carrying the student's handwriting in the paper document to the computer, so that the computer synchronously writes the contents carrying the student's handwriting in the corresponding position of the current electronic document".
The commonalities of the above two methods are: the pen cannot be automatically judged to write on which paper in the writing process, in the former, the paper is changed midway in the ticket filling process to continuously sign or a plurality of pens are crossed to sign, and the system cannot identify at all, so that the electronic ticket and the handwritten ticket are inconsistent. In the latter case, the system cannot recognize the error even if the human judgment is wrong. The fundamental reason is that the pen does not know which page the pen is writing on, and the pen is not fundamentally different from technologies such as a handwriting board, an ultrasonic pen and the like, and cannot meet the actual requirement of the ticket on the job site.

Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
A detailed description will be given below of an electronic system for handwritten tickets according to an embodiment of the present invention with reference to fig. 1 to 6.
Referring to fig. 1, a handwritten ticket electronization system according to an embodiment of the present invention includes a handwritten ticket template 1, an intelligent digital pen 2, a wireless transceiver 3, and a ticket electronization management platform 4, where a handwritten ticket template designer is a software program integrated in the ticket electronization management platform 4, and for example, the handwritten ticket template designer is a software tool capable of outputting a print; the handwritten ticket template designer is used for designing a handwritten ticket template 1 as required, generating a corresponding ticket template electronic form 6 in a ticket electronic management platform 4 while generating a new handwritten ticket template 1, and the intelligent digital pen 2 is used for automatically capturing handwriting data of handwritten information and sending the handwriting data to the ticket electronic management platform 4 through the wireless transceiver 3; the handwritten ticket template 1 is uniformly distributed with circular code patterns, wherein each circular code pattern is unique.
Specifically, each circular code pattern is a circular code data unit, each circular code data unit comprises 6 circular codes distributed in a regular hexagon, and each circular code is located on the gravity center of 6 equilateral triangles formed by diagonal lines of the regular hexagon. And the side length of the regular hexagon is 0.15mm, the diameter of the circular code is 0.05mm, and the corresponding coordinate of each circular code is unique.
Specifically, the "circular code" is composed of a plurality of very fine dots which are regularly arranged according to a special algorithm. The circular code is used for providing the intelligent digital pen 2 with coordinate parameter information, and the written handwriting can be accurately recorded when the intelligent digital pen 2 writes on the ticket. The paper is made intelligent by printing (by a common laser printer, professional printing) a layer of circular code pattern on the common paper. For example, the handwritten ticket template 1 may be set by a handwritten ticket template designer, and after the setting, the handwritten ticket template 1 may be printed on a common a4 paper by a common laser printer or a professional printing method to form a paper version.
Because the side length of the regular hexagon is 0.15mm, the diameter of the circular code is 0.05mm, and the corresponding coordinate of each circular code is unique, further, 44 points are arranged in an area of 1 square millimeter on the handwritten ticket template 1, and only 24 points in the center are taken for coordinate calculation through normal distribution calculation. The 24 dots have a 24 power arrangement of 6, and the dots are arranged according to a special algorithm, and any part of any page is arranged differently. 24 small dots (regular hexagon circular codes) are used for identifying a unique coordinate address (coordinate point), so that coordinates of any one point on 3600 hundred million sheets of A4 paper cannot be overlapped, and the coordinates can not only represent (X, Y) coordinates, but also represent the located handwritten ticket template 1.
Further, the handwritten ticket template 1 includes at least one ticket content item selected from the group consisting of an item, a drawing item, and whether the item is selected, and any one area on the handwritten ticket template 1 is an object with an additional command function. Illustratively, the handwritten ticket template 1 is designed by using a handwritten ticket template designer as required, and according to the content of the ticket content items such as "selection item", "drawing item" and "item" or not, an electronic command such as "writing text", "placing picture photo", "identification object text", "access time", "access coordinate range", "add record" or the like is added to any area "object" on the handwritten ticket, so as to complete a series of electronic tasks. An electronic document, a database table, may be linked to any 1 or 1 segment of 3600 hundred million sheets of the a4 ticket template electronic form 6.
Further, the ticket electronic management platform 5 is a paper data acquisition system, and generates electronic handwriting corresponding to the handwriting data in a corresponding ticket template electronic form according to the received handwriting data. And the ticket electronic management platform 5 matches and determines the ticket template electronic form 6 corresponding to the handwritten ticket template 1 according to any one of the circular code patterns contained in the received handwriting data.
As shown in fig. 6, the intelligent digital pen 2 includes a pen body 201, a pen core 202, a micro high-definition camera 203, a microprocessor 204, a memory 205, and a data communication module 206, wherein the pen core 202 and the micro high-definition camera are disposed at an end of the pen body 201, and the microprocessor 204, the memory 205, and the data communication module 206 are disposed inside the pen body 201. Illustratively, a miniature high-definition camera 203 is built in the front end of the intelligent digital pen 2, and the miniature high-definition camera 203 reads in handwriting of the intelligent digital pen and circular code coordinates of corresponding positions at a speed of 75 pieces per second.
The specific structures and specific arrangement modes of the pen body 201, the pen core 202, the micro high-definition camera 203, the microprocessor 204, the memory 205 and the data communication module 206 are not specifically limited in the embodiments of the present invention, and those skilled in the art can refer to the prior art. It should be noted that the pen body 201 is a housing structure, and is used for installing the pen core 202, the miniature high-definition camera 203, the microprocessor 204, the memory 205, the data communication module 206, and the like; the pen core 202 is used for realizing writing on the handwritten ticket template 1 and generating corresponding handwriting; the miniature high-definition camera 203 is used for shooting the writing handwriting of the pen core 202 on the handwritten ticket template 1 and corresponding note coordinates; the microprocessor 204 is used for converting the handwriting and the corresponding note coordinates photographed by the handwritten ticket template 1 into electric signals.
The intelligent digital pen 2 fills in a paper ticket by a pen and paper in a traditional mode to generate a paper handwritten ticket 5, automatically captures target data of handwritten information, sends the target data to the ticket electronic management platform 4 through the wireless transceiver, synchronously acquires electronic ticket data information consistent with the handwritten ticket, and facilitates background data management and analysis. Illustratively, each intelligent digital pen 2 has its own unique information including a serial number, and can synchronously record important parameters such as pen-down time, and perform easy and effective security management to prevent data tampering or counterfeiting.
Referring to fig. 2, in the prior art, a point representing information is distributed around an imaginary cross line with reference to the center of the cross line, and the point representing information can be distributed at 4 positions around the imaginary cross line with reference to the center of the cross line, thereby recording 4 digits, i.e., 2 bits of information. In this way, the coordinate information can be embedded in the paper by printing the full-page dot matrix as shown in fig. 2 on the paper, and the information such as written characters can be directly input into the computer by writing on the paper through the pen-type optical reader. Unfortunately, the reference considered by the inventor of this code is hypothetical, where two similar locations of coordinates can be used as a constant when embedded as coordinate information, and where the coordinates can be identified when the reader is moved. However, if the recognizer is just a point read, as shown in fig. 4, the code value cannot be recognized directly as in the case of the general two-dimensional bar code.
Aiming at the defects existing in the prior art, the phenomenon of hexagonal structure can be found in compound eyes of insects and retina photoreceptor cells of human eyes, and the hexagonal grid is thought to have better geometric characteristics including symmetry, adjacent consistency, adjacent equidistance and the like, the invention provides a circular code technology as shown in figure 5, and proposes that an information point is distributed by taking a virtual center formed by connecting 6 vertexes of a regular hexagonal rectangle as a reference, the point representing the information can be distributed on 6 positions around the virtual center as the reference, and 8 numbers, namely multi-bit information can be recorded.
By adopting the storage and addressing method of the regular hexagon grid sampling data, for sampling of the analog image signal of the handwritten ticket, two linear independent vectors are needed for complete description, and the conventional common rectangular sampling grid is that the two sampling vectors are orthogonal. Under this scheme, the sampling point can be conveniently described by an orthogonal coordinate system, and can be conveniently mapped to a two-dimensional array for access, and from the sampling efficiency viewpoint, a rectangular grid is not optimal, as shown in fig. 3, and for the ink dot signal in the handwritten ticket system, the sampling scheme with the highest sampling efficiency is a regular hexagonal sampling grid. Compared with the conventional rectangular sampling and processing, the hexagonal sampling data processing method has the advantages that the hexagonal sampling efficiency is high, the data volume can be reduced by 13.4%, the calculation efficiency is higher, the calculation amount is saved by 25% -58%, and the filter performance under the same condition is higher.
The invention provides a handwritten ticket electronization system, which adopts a handwritten ticket template which is uniformly distributed with circular code patterns, wherein each circular code pattern is unique, and an intelligent digital pen is used for automatically capturing handwriting data and circular code coordinate data of handwritten information and sending the handwriting data and the circular code coordinate data to a ticket electronization management platform through a wireless transceiver; in the writing process, the ticket electronic management platform matches and determines a ticket template electronic form corresponding to a currently used handwritten ticket template according to any one of circular code coordinate data contained in the handwriting data, and then can generate an electronic handwriting corresponding to the current handwriting data in the corresponding ticket template electronic form, so that the problem that an intelligent pen in the prior art cannot write under the background of any ticket is solved, the automatic identification function of the handwritten ticket template under the conditions of any pen, multiple cross-signing, ticket switching and the like is realized, namely the what you see is what you get of the intelligent pen is realized, an electronic copy of the user ticket is obtained by carrying out digital processing on information manually filled by the user, the original appearance of the manually filled ticket can be completely and effectively stored, the authenticity and the effectiveness of the ticket are ensured, and the signing and filling of the ticket are not limited by time and space, the method is beneficial to promoting safe and fine management by trace management, and has good social benefit and economic benefit.
