Description

Technical Field

[0001] The present invention belongs to the technical field of financial document processing, and in particular relates to a cross-regional business accounting method and system based on financial sharing. Background Art

[0002] With the advent of the digital age, new generation digital technologies such as artificial intelligence, big data, mobile Internet, Internet of Things, and cloud computing have been widely used in corporate management, and financial digital transformation has become an inevitable trend. At present, more and more large group companies are promoting corporate financial digital transformation through the construction of financial shared centers. With the increasing scale of enterprises and the continuous innovation of business models, the traditional decentralized financial management model faces more and more problems, such as institutional redundancy, high management costs, difficulty in coordination, and difficulty in quickly providing data support for management decisions. The traditional financial management model has become a bottleneck restricting the development of large group companies, and the financial sharing model has emerged under this background.

[0003] At present, in the process of reimbursement document accounting, especially for large enterprises above a certain scale, due to the geographical limitations of the company's business market distribution, subsidiaries or city offices, reimbursement is difficult and the operation is low, which often leads to advance payment by front-line employees. Long-term accumulation can easily cause employees to be passive and slow down, affecting production efficiency. In order to solve the above-mentioned problems of "inconvenient" offline reimbursement for cross-regional enterprises, "difficult to unify" accounting standards, and "unintelligent" business processes, it is urgent to design a cross-regional business reimbursement method and system based on financial sharing to solve the above technical problems. Summary of the invention

[0004] In order to solve the above-mentioned deficiencies in the prior art, the purpose of the present invention is to overcome the existing deficiencies and provide a cross-regional business reimbursement method based on financial sharing, including the following:

[0005] Get all collected uploaded documents for analysis:

[0006] If it is detected that the uploaded document meets the review requirements, the uploaded document is transmitted to a secondary review;

[0007] If it is detected that the uploaded document does not meet the audit requirements, the uploaded document is returned to the collection source;

[0008] Based on the secondary review, the uploaded documents that meet the initial review requirements are calibrated:

[0009] If the secondary review requirements are met, a financial voucher file is generated based on the uploaded document information;

[0010] If the secondary review requirements are not met, the uploaded document will be returned to the collection source.

[0011] As a further optimization of the above solution, the acquisition of the uploaded document includes the following:

[0012] Detect any upload document collection instruction;

[0013] Based on the instruction, take a photo of any uploaded document and detect the taken image:

[0014] If the captured image meets the collection requirements, the captured image is stored to generate an upload document and perform information analysis;

[0015] If the captured image does not meet the acquisition requirements, the current image acquisition is terminated.

[0016] As a further optimization of the above solution, the method for detecting the captured image includes the following:

[0017] Acquire the image capture area after receiving the document capture instruction;

[0018] Set an image capturing area to consist of a control area and a generation area, capture an image based on the image capturing area, and detect the content of the image:

[0019] If no data is detected in the control area, the current image acquisition is terminated;

[0020] If it is detected that the control area has data, based on the image information of the control area, the readable information of the control area is recorded to form a control area file;

[0021] Continue to detect the captured image content, store the readable information of the generation area, and form a generation area file.

[0022] As a further optimization of the above solution, before storing the readable information of the generation area and forming the generation area file, it also includes the following:

[0023] Processing the captured image content into a machine-written image;

[0024] Based on the machine-written image, all pixel points are traversed, and all black pixels of the machine-written image are projected on the vertical axis respectively. If the coordinates of any black pixel are (x, y), the corresponding projection coordinate Tou is:

[0025]

[0026] In the above formula, ρ represents the deflection angle; record the number of Tou that completes the vertical axis projection n;

[0027] Based on the statistically obtained Tou number Num_tou, calculate the probability value P_Tou of any projection coordinate;

[0028] Calculate the mathematical expectation of the projected coordinates

[0029] Then the mathematical variance of the projection coordinate Tou is

[0030] As a further optimization of the above scheme, the method further includes the following:

[0031] Construct a deflection threshold [-a, a] of the deflection angle ρ, and calculate the mathematical variance corresponding to all deflection angles ρ within the deflection threshold based on formula (3);

[0032] Based on each deflection angle ρ and the corresponding mathematical variance, a variance-deflection angle line graph is generated; the deflection angle ρ is used as a variable to construct a mathematical variance fitting quadratic function:

[0033] D Tou =f 2 (ρ) = k 0 +k 1 ρ+k 2 ρ 2 (4)

[0034] In the above formula, k 0 , k 1 and k 2 The coefficients of the quadratic function fitted for the mathematical variance;

[0035] Get the minimum mathematical variance, corresponding to the perfect deflection angle ρ, and set f 2 (ρ) = 0, then the perfect deflection angle ρ is the deflection angle value of the captured image

[0036] As a further optimization of the above solution, the method further includes the following:

[0037] Based on the text content of the control area file and the generated area file, M, S and T class arrays are generated accordingly;

[0038] Set the trigger key value of each type of array, recorded as M = {m 1 ,…m a},S={s 1 ,…s b}, T={t 1 ,…t c};

[0039] set up

[0040] The uploaded receipt document is tested. Based on the trigger key value of each type of array, the text content of the control area file and the generation area file is written in accordance with the set trigger key value. If the trigger key value of the control area file and the generation area file successfully matches, it is set to 1, and if it fails, it is set to 0, then the write operation result test is performed:

[0041] If any matching value of 0 exists in the M-type array, the current write operation is marked invalid, and the uploaded document is returned to the collection source;

[0042] If the S-type array and the T-type array successfully match and are greater than the first threshold, the uploaded document is transmitted to a secondary review; otherwise, the uploaded document is returned to the collection source.

[0043] As a further optimization of the above solution, the first threshold determination includes the following:

[0044] Assume that all weights of the S-type array and the T-type array are PowerA and PowerB respectively, the failed matching weight of the S-type array is PowerAN, and the failed matching weight of the T-type array is PowerBN, then the first threshold Ψ is represented as:

[0045]

[0046] As a further optimization of the above solution, the S-type array is provided with a special trigger key value. If the special trigger key value is greater than a second threshold value, the uploaded receipt document is transmitted to a secondary review.

[0047] The present invention also discloses a cross-regional business reimbursement system based on financial sharing, which is characterized in that the system includes the following:

[0048] Document collection module, used to obtain all collected uploaded documents;

[0049] Document analysis module, used to analyze all collected and uploaded documents:

[0050] If it is detected that the uploaded document meets the review requirements, the uploaded document is transmitted to a secondary review;

[0051] If it is detected that the uploaded document does not meet the audit requirements, the uploaded document is returned to the collection source;

[0052] The bill review module is used to calibrate the uploaded bill documents that meet the initial review requirements based on the secondary review:

[0053] If the secondary review requirements are met, a financial voucher file is generated based on the uploaded document information;

[0054] If the secondary review requirements are not met, the uploaded document will be returned to the collection source.

[0055] A computer-readable storage medium for storing a computer program or code, characterized in that when the computer program or code is executed by a processor, a cross-regional business reimbursement method based on financial sharing as described in any one of the claims is implemented.

[0056] The present invention adopts the above technical solution, which has the following beneficial effects compared with the prior art:

[0057] 1. In order to solve the above-described problems of "inconvenience" of offline reimbursement for cross-regional enterprises, "difficult to unify" accounting standards, and "unintelligent" business processes, the present invention designs and proposes a cross-regional business reimbursement method based on financial sharing. By initially reviewing the document uploaded by the employee, when the document review meets the requirements of the reimbursement process, it is pushed to manual for rapid review and approval; when abnormalities are detected in the reimbursement materials, the present invention can handle them intelligently, assist employees to quickly complete the correction, and assist them to quickly complete the reimbursement process. The present invention realizes online travel reimbursement, accurate accounting of expenses, shortens the time for business departments to submit reports and the time for leaders to approve, improves work efficiency, and reduces the risks of duplicate invoice reimbursement.

[0058] 2. Before approving the reimbursement documents, the present invention designs an image planning method, that is, the reimbursement form and the invoice document are identified and detected separately. That is, when the image is collected, if the control area is not detected, it indicates that the current operation lacks the reimbursement form, that is, the current round of image entry is invalid, and the employee can correct the error and re-operate according to the feedback; if the control area is successfully identified, a control area file is generated based on the identified control area to record the reimbursement form.

[0059] 3. The present invention takes into account that during the image shooting process, due to the uncontrollable operation of employees, the reimbursement form or invoice document may have a large offset, which is not conducive to the formation of effective record files. Therefore, an innovative method is proposed that can be adjusted in real time according to the image settings to facilitate the formation of stable and effective record files, which greatly improves the work efficiency of electronic review in the reimbursement business process and reduces unnecessary invalid input and invalid detection.

[0060] 4. The technology of the present invention provides a fault-tolerant threshold, namely, a first threshold, so that for similar situations, the present invention allows some key-value matching anomalies to exist, and still treats them as valid entries within the allowed range. The secondary review strengthens the review of this part, which can ensure the effective implementation of the employee's reimbursement process on the one hand, and on the other hand, through the intelligent review mechanism, error correction and troubleshooting are carried out in advance, and abnormal items within a reasonable range are marked, which facilitates the secondary review process and has a good effect.

[0061] 5. The special trigger key value of the present invention is manually assigned, that is, manual marking is performed, so that when this part is identified, an additional second threshold match is performed. When it is outside the second threshold match range, the secondary review will be directly activated, and the current reimbursement process will be directly pushed to the secondary review, which is conducive to strengthening the review attention to special events and effectively promoting the review efficiency.

[0066] It should be understood that the specific embodiments described herein are only used to explain the present invention, and are not used to limit the present invention.

[0067] like Figure 1-3 As shown, the embodiment of the present invention discloses a cross-regional business reimbursement method based on financial sharing, which specifically includes the following steps:

[0068] Get all collected uploaded documents for analysis:

[0069] If it is detected that the uploaded document meets the review requirements, the uploaded document is transmitted to a secondary review;

[0070] If it is detected that the uploaded document does not meet the audit requirements, the uploaded document is returned to the collection source;

[0071] Based on the secondary review, the uploaded documents that meet the initial review requirements are calibrated:

[0072] If the secondary review requirements are met, a financial voucher file is generated based on the uploaded document information;

[0073] If the secondary review requirements are not met, the uploaded document will be returned to the collection source.

[0074] Specifically, in the process of reimbursement document accounting, currently enterprises, especially large enterprises above a certain scale, are limited by the geographical limitations of the company's business market distribution, subsidiaries or city offices. Reimbursement is difficult and the operation is low during the work process, which often leads to advance payment by front-line employees. Long-term accumulation can easily cause employees to be passive and lazy, affecting production efficiency. In order to solve the above-mentioned problems of "inconvenient" offline reimbursement of cross-regional enterprises, "difficult to unify" accounting standards, and "unintelligent" business processes, the present invention designs and proposes a cross-regional business reimbursement method based on financial sharing. Through the initial review of the document documents uploaded by the employees, when the document review meets the requirements of the reimbursement process, it is pushed to manual for rapid review and approval; when the reimbursement materials are detected to be abnormal, the present invention can intelligently process, assist employees to quickly complete the correction, and assist them to quickly complete the reimbursement process. The present invention realizes online travel reimbursement, accurate expense accounting, shortens the time for business departments to submit reports, and the time for leaders to approve, improves work efficiency, and reduces the risks of repeated invoice reimbursement.

[0075] Specifically, the acquisition of uploaded document includes the following:

[0076] Detect any upload document collection instruction;

[0077] Based on the instruction, take a photo of any uploaded document and detect the taken image:

[0078] If the captured image meets the collection requirements, the captured image is stored to generate an upload document and perform information analysis;

[0079] If the captured image does not meet the acquisition requirements, the current image acquisition is terminated.

[0080] Specifically, the method for detecting the captured image includes the following:

[0081] Acquire the image capture area after receiving the document capture instruction;

[0082] Set an image capturing area to consist of a control area and a generation area, capture an image based on the image capturing area, and detect the content of the image:

[0083] If no data is detected in the control area, the current image acquisition is terminated;

[0084] If it is detected that the control area has data, based on the image information of the control area, the readable information of the control area is recorded to form a control area file;

[0085] Continue to detect the captured image content, store the readable information of the generation area, and form a generation area file.

[0086] More specifically, before the approval of the reimbursement documents, the present invention designs an image planning method, that is, the reimbursement form and the invoice document are separately identified and detected, that is, during image acquisition, if the control area is not detected, it indicates that the current operation lacks the reimbursement form, that is, the current round of image entry is invalid, and the employee can self-correct and re-operate according to the feedback; if the control area is successfully identified, a control area file is generated based on the identified control area to record the reimbursement form. Similarly, a corresponding generation area file can be generated to record the invoice document; because the reimbursement form is extracted as key information in the reimbursement process, the reimbursement form thus formed has less information and four prominent elements compared to the invoice document, which is convenient for technical processing. It should be particularly noted that if the current image acquisition is terminated, the present invention supports prompting employees of operating errors by means of electronic information or voice broadcasting, and this technology is a conventional warning technology and will not be described in detail here.

[0087] Specifically, before storing the readable information in the generation area and forming the generation area file, the following is also included:

[0088] Processing the captured image content into a machine-written image; it is particularly important to note that, since it is necessary to process the expense reimbursement form or invoice document through an intelligent solution, it is necessary to process the captured image into a style that is easy for the machine to recognize and has high accuracy as much as possible. As a technical means of the present invention, the present invention uses grayscale value processing to process the image, and then performs binarization processing to form a machine-written image with high contrast and less interference color for subsequent further processing;

[0089] Based on the machine-written image, all pixel points are traversed, and all black pixels of the machine-written image are projected on the vertical axis respectively. If the coordinates of any black pixel are (x, y), the corresponding projection coordinate Tou is:

[0090]

[0091] In the above formula, ρ represents the deflection angle; record the number of Tou that completes the vertical axis projection n;

[0092] Based on the statistically obtained Tou number Num_tou, calculate the probability value P_Tou of any projection coordinate;

[0093] Calculate the mathematical expectation of the projected coordinates

[0094] Then the mathematical variance of the projection coordinate Tou is

[0095] in, It is expressed as the product of each projection coordinate and its corresponding projection coordinate probability value, Tou i -E Toui It is represented by the difference between the current projection coordinate value and its mathematical expectation, and PToui is the probability value of the corresponding projection coordinate;

[0096] Construct a deflection threshold [-d, d] of the deflection angle ρ, and calculate the mathematical variance corresponding to all deflection angles ρ within the deflection threshold based on formula (3);

[0097] Based on each deflection angle ρ and the corresponding mathematical variance, a variance-deflection angle line graph is generated; the deflection angle ρ is used as a variable to construct a mathematical variance fitting quadratic function:

[0098] D Tou =f 2 (ρ) = k 0 +k 1 ρ+k 2 ρ 2 (4)

[0099] In the above formula, k 0 , k 1 and k 2 The coefficients of the quadratic function fitted for the mathematical variance;

[0100] Get the minimum mathematical variance, which corresponds to the perfect deflection angle ρ, set f 2 (ρ) = 0, then the perfect deflection angle ρ is the deflection angle value of the captured image The present invention takes into account that during the image shooting process, due to the uncontrollable operation of employees, the reimbursement form or invoice document may have a large offset, which is not conducive to the formation of a valid record file. Therefore, an innovative method is proposed which can be adjusted in real time according to the image setting to facilitate the formation of a stable and effective record file, which greatly improves the work efficiency of electronic review in the reimbursement business process and reduces unnecessary invalid input and invalid detection.

[0101] Specifically, the design method of the present invention also includes the following:

[0102] Based on the text content of the control area file and the generated area file, M, S and T class arrays are generated accordingly;

[0103] Set the trigger key value of each type of array, recorded as M = {m 1 ,…m a},S={s 1 ,…s b}, T={t 1 ,…t c};

[0104] Assume that m 1 = Birth m 1 , for m 2 = Birth m 2 ,…, for m a = Birth m a ; for s 1 =S11 + raw s 12 + … + raw s 1b ;

[0105] The above a, b, and c represent the number of trigger key values included in the corresponding arrays, for m 1 is the value of m obtained from the control area 1 raw m 1 is the value of m obtained from the generation area 1 raw s 11 is the first item of the trigger key value in the S - type array in the generation area, and other parameter information can be obtained by analogy 1

[0106] It should be particularly noted that based on the data characteristics of the reimbursement form and invoice documents, the present invention divides them into three types of arrays. The M - type array mainly stores the main identification information of invoices, such as the purchaser's name, invoice type, etc.; the S - type array mainly stores information such as the invoiced amount and the number of bills; the T - type array mainly stores information such as the seller, invoice number, and date. According to the above - mentioned division information, employees can fill in the reimbursement form according to the preset reimbursement form layout, and the comprehensive information has a strict corresponding relationship with the invoice documents. Based on the above design, the present invention splits and classifies the complex reimbursement form data information and invoice document information into new arrays for storage, which is convenient for subsequent accurate analysis and data sorting;

[0107] Detect the uploaded document. Based on the trigger key values of each type of the above - mentioned arrays, write the text content of the control area file and the generation area file respectively according to the set trigger key values. Assume that the successful matching of the trigger key values of the control area file and the generation area file is 1, and the failure is 0, then perform the write operation result detection:

[0108] If there is any matching value of 0 in the M - type array, mark the current write operation as invalid and return the uploaded document to the collection source;

[0109] If the successful matching of the S - type array and the T - type array is greater than the first threshold, transmit the uploaded document to the secondary review; otherwise, return the uploaded document to the collection source;

[0110] Specifically, when detecting the uploaded document, the present invention writes according to the set trigger key values based on the reimbursement form data information and invoice document information, and can quickly judge the recognition situation of the control area and the generation area through the corresponding relationships of the different arrays given above, and make clear marks

[0111] ​The present invention provides a specific embodiment. For example, if the company name collected in the control area is Company A, and the company name collected in the generation area is Company A1, then due to the certainty of the invoice elements, it is indicated that the current invoice document cannot be matched with the reimbursement form, and there may be an error in providing the invoice or an abnormal recognition, and the employee needs to be notified to handle the corresponding processing; if the total amount of the reimbursement form filled in by the employee is Count1, and the total amount of the invoice document collected in the generation area is Count2, since Count1 does not match Count2, it is indicated that the employee's reimbursement amount does not match the provided invoice amount or the recognition is abnormal, and it is necessary to conduct a focused review; it is particularly pointed out that based on this situation, the technology of the present invention provides a fault-tolerant threshold, that is, a first threshold, so that the present invention allows for partial key value matching anomalies in similar situations, and within the allowed range, it is still regarded as a valid entry, and the strength of this part of the review is strengthened through secondary review. On the one hand, it can ensure that the employee's reimbursement process is effectively carried out, and on the other hand, through the intelligent review mechanism, error correction and troubleshooting are carried out in advance, and abnormal items within a reasonable range are marked, which facilitates the work process of the secondary review and has a good effect.

[0112] Specifically, the first threshold determination includes the following:

[0113] Assume that all weights of the S-type array and the T-type array are PowerA and PowerB respectively, the failed matching weight of the S-type array is PowerAN, and the failed matching weight of the T-type array is PowerBN, then the first threshold Ψ is represented as:

[0114]

[0115] More specifically, the present invention assigns weights to the S-type array and the T-type array respectively, thereby improving the efficiency of the matching exception processing of the present invention, and ensuring that the employee's reimbursement process is effectively carried out within a reasonable range.

[0116] The present invention provides another embodiment. During the matching processing of the generation area, the present invention detects that there are partial matching failures, such as there are 5 matching events in the S-type array and 2 matching events are successful; there are 10 matching events in the T-type array and 4 matching events are successful. According to the first threshold Ψ matching formula, the current S-type array matching success factor is 0.5, and the overall matching success factor of the S-type array and the T-type array is 0.6, which meets the first threshold requirement, indicating that in this case, there is an abnormality in the matching, but it does not affect the reimbursement process, and can be optimized and adjusted through secondary review.

[0117] Specifically, the S-type array is provided with a special trigger key value. If the special trigger key value is greater than the second threshold value, the uploaded document is transmitted to the secondary review; the special trigger key value of the present invention is manually assigned, that is, manually marked, so that when the part is identified, the second threshold value is additionally matched, and when it is outside the second threshold value matching range, the secondary review will be directly activated; the present invention provides an embodiment to illustrate that the single amount of the invoice document can be preset not to exceed Count3, but if there is a single amount exceeding Count3 after the generation area matching, the current reimbursement process is directly pushed to the secondary review, which is conducive to strengthening the audit attention to special events and effectively promoting the audit efficiency; it should be particularly noted that the special trigger key value of the present invention can be marked for abnormal data, error-prone points or other keywords, and according to different marking targets, there is a corresponding second threshold range, which will not be described in detail here. Those skilled in the art should be able to understand and master the technology based on the description of this embodiment. The image-to-text conversion of the present invention is an existing conventional technology and will not be described here.

[0118] The present invention also discloses a cross-regional business reimbursement system based on financial sharing, which is characterized in that the system includes the following:

[0119] Document collection module, used to obtain all collected uploaded documents;

[0120] Document analysis module, used to analyze all collected and uploaded documents:

[0121] If it is detected that the uploaded document meets the review requirements, the uploaded document is transmitted to a secondary review;

[0122] If it is detected that the uploaded document does not meet the audit requirements, the uploaded document is returned to the collection source;

[0123] The bill review module is used to calibrate the uploaded bill documents that meet the initial review requirements based on the secondary review:

[0124] If the secondary review requirements are met, a financial voucher file is generated based on the uploaded document information;

[0125] If the secondary review requirements are not met, the uploaded document will be returned to the collection source.

[0126] It should be noted that the technical means for implementing another embodiment of the present invention, a cross-regional business reimbursement system based on financial sharing, is the same as that of a cross-regional business reimbursement method based on financial sharing, and thus will not be described in detail herein.

[0127] The above description is only a preferred embodiment of the present application and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the present application is not limited to the technical solution formed by a specific combination of the above technical features, but should also cover other technical solutions formed by any combination of the above technical features or their equivalent features without departing from the inventive concept.
