the method comprises the steps of obtaining a real signal final value and a false signal final value through analysis, obtaining a reporting real index based on the real signal final value and the false signal final value, comparing the reporting real index of a reimbursement bill with a preset reporting real index threshold, generating a screening signal according to a comparison result, wherein the screening signal comprises a screening qualified signal and a screening failure signal, and sending the screening qualified signal or the screening failure signal to a reimbursement bill processing module.
4. A data transmission management system for self-service reimbursement terminals for enterprise notes according to claim 3, wherein the analysis of the corresponding amount of each reimbursement item is as follows:
acquiring names and amounts corresponding to reimbursement items in reimbursement sheets, comparing reimbursement amounts corresponding to the names of the reimbursement items with limit amounts corresponding to reimbursement items in a business database one by one, generating a quota real signal when the amount corresponding to a reimbursement item is consistent with the bill billing amount, and otherwise generating quota false signals, thereby obtaining the quota real signals and the quota false signals;
classifying the raw bill billing information according to the billing information of each raw bill, and summing the raw bill amounts under each class to obtain the total amount corresponding to each class;
and comparing the sum of each reimbursement item in the reimbursement list with the total sum corresponding to each category one by one, generating a sum real signal when the sum corresponding to a reimbursement item is consistent with the limit sum corresponding to each item in the business database, and otherwise, generating a sum false signal, thereby obtaining the sum real signal and the sum false signal.
5. The data transmission management system for the self-service reimbursement terminal of the enterprise bill according to claim 1, wherein the specific way of identifying the screening signal is as follows:
acquiring a screening signal sent by a verification module, marking the reimbursement bill as a standard reimbursement bill when the screening signal is a screening qualified signal, and marking the reimbursement bill as a illegal reimbursement bill when the screening signal is a screening failure signal;
when the reimbursement bill is a standard reimbursement bill, extracting the name of the applicant, the department, the reimbursement amount and the reimbursement date of the standard reimbursement bill as transmission data, sending the transmission data to a transmission management module, and storing pictures of all original bills corresponding to the reimbursement bill and data corresponding to all original bills into a service database;
when the reimbursement bill is the illegal application bill, the name of the applicant of the illegal reimbursement bill is extracted, and a corresponding prompt is sent to the applicant.
6. The data transmission management system for the self-service reimbursement terminal of the enterprise bill according to claim 1, wherein the analysis process of the received data by the receiving module is as follows:
the verification module decrypts the data sent by the transmission management module by using the private key to obtain a random number list, and calculates a hash value of the plaintext data according to the plaintext data to obtain a final hash value;
and extracting each digit corresponding to the integer part of the reimbursement amount in the comprehensive list according to the random number list to obtain an original hash value and the integer part of the reimbursement amount, comparing the original hash value with a final hash value, inputting the name of the applicant, the affiliated department, the reimbursement date and the reimbursement amount into the system when the original hash value is equal to the final hash value, and sending a request to the self-service reimbursement terminal when the original hash value is not equal to the final hash value, so that the self-service reimbursement terminal resends the data.
