Description

Technical Field

[0001] This application relates to the field of Internet of Things technology, and specifically relates to a method, system, electronic device and medium for deducting parking coupons. Background Art

[0002] With the acceleration of the urbanization process and the development of the automotive industry, more and more people choose to travel by private car, which has led to increasingly prominent parking problems in cities. Especially in commercial areas, good parking facilities and preferential policies can not only provide convenience for customers, but also effectively attract more customers and increase the turnover of businesses. Therefore, many businesses have begun to launch various parking coupons to reduce the parking fee burden of customers.

[0003] Currently, the deduction method of existing parking coupons is usually fixed. Merchants set the face value of the coupons in advance and distribute them to users. When users park, they can use the coupons to deduct a certain amount of parking fees. However, in actual applications, when users pay parking fees, due to the way of distributing coupons by deducting first and then using, it is impossible to estimate the parking fees of users, which often leads to a mismatch between the face value of the distributed coupons and the actual parking fees. Summary of the Invention

[0004] This application provides a method, system, electronic device and medium for deducting parking coupons, which has the effect of matching the actual deducted parking coupons according to the parking fees of users.

[0005] In a first aspect, this application provides a method for deducting parking coupons, including:

[0006] Generating a first parking coupon according to the current available balance and the passenger flow, determining the first discount amount of the first parking coupon as the frozen amount, and freezing the frozen amount in the available balance;

[0007] When the target user uses the first parking coupon, determining whether the first discount amount is greater than or equal to the first consumption amount of the target user in the parking lot;

[0008] If the first discount amount is greater than or equal to the first consumption amount of the target user in the parking lot, canceling the frozen amount;

[0009] If the first discount amount is less than the first consumption amount of the target user in the parking lot, reissuing a second parking coupon according to the second consumption amount of the target user at the merchant side.

[0010] By adopting the above technical solution, the intelligent determination of the face value of the first-round parking coupon and the freezing of the corresponding amount have achieved the precision of fund use, which not only meets the payment needs of the first use but also prevents the risk of insufficient balance. After the user's consumption occurs, the system can verify the actual amount deducted by the coupon to achieve accurate write-off of the frozen amount, avoid repeated or incorrect freezing of funds, and improve the efficiency of fund use. When the first-round coupon cannot fully cover the user's parking fee, the system can quickly capture and obtain the remaining fee of the user and issue a second-round supplementary coupon of the same amount. Through this technical solution, the coupon is distributed in a way of "use first and then deduct". The coupon is distributed and deducted according to the actual parking fee of the parking lot users, and the un-deducted coupon amount can be recovered and returned to the merchant after deducting the parking fee. This enables the property side of the parking lot to view more clearly the details of the coupon amount provided for the merchant, and the merchant can understand more clearly the actual deducted amount of the coupon, improving the data transparency of coupon distribution, achieving the effect of matching the distributed coupon amount with the actual parking fee and actual offset.

[0011] Optionally, send the historical parking coupon distribution quantity, the historical parking coupon distribution amount, and the historical passenger flow to the property side that administers the parking lot, so that the property side determines the available balance according to the historical parking coupon distribution quantity, the historical parking coupon distribution amount, and the historical passenger flow; receive the available balance allocated by the property side.

[0012] By adopting the above technical solution, a data connection between the merchant side and the property side is established, realizing the collaborative cooperation between the two parties in parking coupon management. The merchant side actively summarizes and provides key business data such as historical coupon issuance and passenger flow, enabling the property side to more accurately evaluate and analyze the merchant's fund needs, thereby determining an available balance amount that not only conforms to the merchant's actual situation but also takes into account risks, and then directly allocating this amount to the merchant side for use. This method of determining the balance supported by business data not only improves the efficiency of fund use but also reduces the fund risks caused by the merchant's own prediction errors. The clear division of labor also enables both parties to focus on their respective strengths and improve efficiency. With the help of the professional fund management ability of the property side, the merchant can provide a more stable and efficient parking payment service, which not only improves the payment system but also ultimately enhances the user's parking consumption experience. Therefore, this solution enhances the business synergy between the merchant and the property, and is conducive to both parties to jointly improve the quality and efficiency of the payment service.

[0013] Optionally, predict the parking coupon consumption amount according to the passenger flow, and determine the target ratio between the parking coupon consumption amount and the available balance; generate the first parking coupon according to the target ratio.

[0014] By adopting the above technical solution, the consumption amount of parking coupons is evaluated, so that the approximate amount of funds required for the current issuance of coupons can be clearly understood. After clarifying the scale of capital requirements, the target ratio is further determined in combination with the available balance, that is, the dynamic balance between the estimated consumption amount and the available balance is achieved, which not only meets the issuance requirements but also ensures the safety of funds. On this basis, parking coupons with a rich variety of denominations are generated, which can make the coupon value meet the ratio requirements and improve the convenience of use. Because the denominations are reasonable, it can effectively reduce the situation of insufficient funds after the first round of use and ensure the smooth operation of subsequent payments. This solution enables merchants to rely on accurate data prediction to adjust the intensity of capital investment in real time, not only making management more refined but also significantly improving the capital use efficiency. At the same time, the preferential intensity can be controlled to achieve a double harvest of resource utilization and marketing effects. In summary, this solution can significantly improve the management level of merchants' parking coupons, enabling merchants to maximize the efficiency of their own capital use while meeting the payment experience of users.

[0015] Optionally, determine the amount difference between the frozen amount and the first consumption amount; in the frozen amount, return the amount difference to the available balance at the merchant end.

[0016] By adopting the above technical solution, calculate the difference between the frozen amount and the actual consumption amount, and the amount of preferential funds actually used by the user can be clearly seen. Release the balance that does not need to be frozen back to the merchant's available balance account, which can avoid the situation where funds are locked for a long time but cannot be used, and improve the capital use efficiency. The increased available balance can support the merchant's subsequent payment needs and ensure the smooth operation of the payment system. The returned difference also reflects the current situation of coupon use, and merchants can evaluate and adjust the preferential activity strategy based on this as a basis for future decisions. Adjust the available balance and the frozen balance in real time to maintain the dynamic balance between the two, reduce the payment risk, and avoid the problem of too much or too little available balance, realizing the reasonable allocation of funds, so that merchants can conduct more refined and efficient user experience management. In summary, this solution realizes the improvement of capital use efficiency and the control of payment risk, which is beneficial for merchants to provide better payment services and user experience.

[0017] Optionally, determine the preferential amount difference according to the consumption amount of the parking coupon and the first consumption amount; judge whether the preferential amount difference is less than the preset amount difference; if the preferential amount difference is less than the preset amount difference, reissue the second parking coupon corresponding to the preferential amount difference; if the preferential amount difference is greater than the preset amount difference, match the corresponding second parking coupon according to the second consumption amount.

[0018] By adopting the above technical solution, the difference in the preferential amount of the user can be calculated, and the specific remaining payment requirement of the user can be clearly known. After clarifying the difference, flexible handling can be carried out according to the size of the difference. If the difference is very small, the second-round parking vouchers will be directly reissued in equal amounts, simplifying the operation process and improving the processing efficiency. If the difference is large, it is necessary to match the second-round parking vouchers with more appropriate face values and reissue them to the user, which can prevent the problem of excessive or insufficient face values of the reissued vouchers and achieve precise matching of the face value with the actual needs of the user. In this way, both the processing efficiency can be taken into account and precise management can be achieved, maximizing the satisfaction of the user's payment requirements in different situations and ensuring the smooth operation of the payment system. The reissue of reasonable face values can improve the capital use efficiency and reduce the additional costs caused by the reissued vouchers. The user's parking payment experience is also optimized and improved. This solution realizes the optimization of the reissue management of the merchant's parking vouchers, enabling the merchant to respond efficiently and precisely to the changes in the user's payment requirements, not only enhancing user stickiness but also gaining an advantage in the competition for the merchant.

[0019] Optionally, determine whether the available amount of the merchant side is less than a preset amount; if the available amount of the merchant side is less than the preset amount, obtain the remaining business hours of the merchant side on the same day; according to the remaining business hours, predict the corresponding temporary supplementary amount, and supplement the balance corresponding to the temporary supplementary amount to the available balance of the merchant side.

[0020] By adopting the above technical solution, the usage of the balance on the merchant side is monitored in real time. When the available balance is lower than the preset safety amount, the remaining business hours of the merchant can be automatically obtained. Based on the remaining time, the amount of additional payment transactions that may occur during the current time period can be accurately predicted. The corresponding amount is extracted from the new transaction and supplemented to the available balance of the merchant side. The dynamic monitoring of the balance usage is realized, and the balance can be actively and precisely supplemented, which not only ensures that the payment requirements in the subsequent time can be met but also avoids the situation of excessive freezing of funds and the resulting decline in the capital utilization rate. The active and intelligent balance supplementation method also reduces the manual operation cost. The merchant can rely on this intelligent balance supplementation mode to avoid the sudden shortage of balance when closing the store, ensure the stable and efficient operation of the payment system, and bring a better consumer experience. This solution overall realizes the dynamic and precise management of the merchant's balance, not only optimizing the capital use efficiency but also enabling the merchant to better establish brand trust and enhance the commercial value with a differentiated marketing strategy.

[0021] Optionally, obtain the issuance duration of the un-redeemed parking vouchers in the first parking vouchers; determine whether the issuance duration exceeds the preset validity period corresponding to the first parking vouchers; if the issuance duration exceeds the preset validity period, mark the un-redeemed parking vouchers as invalid, and return the target amount corresponding to the un-redeemed parking vouchers to the available balance of the merchant side.

[0022] By adopting the above technical solution, the specific issuance duration of the unwritten-off parking coupons can be obtained, and the coupons that have exceeded the preset validity period can be judged, and all these overdue coupons are marked as invalid status. For these invalid coupons, the corresponding amount freeze can be automatically lifted and returned to the available balance account on the merchant side. In this way, the situation where funds are frozen for a long time but cannot be used can be avoided, improving the efficiency of fund use. The increased available balance can support subsequent payment requirements and ensure the stable operation of the payment system. The returned frozen funds also facilitate the merchant to conduct more refined monitoring and management of the available balance. Analyzing the unwritten-off coupon data can also help the merchant evaluate and adjust the current coupon issuance strategy to improve the coupon issuance management level. This solution realizes the dynamic monitoring of the validity period of unwritten-off coupons, not only recovers resources, improves the use efficiency of coupons, but also significantly optimizes the allocation efficiency of funds on the merchant side and reduces the payment cost.

[0023] In the second aspect of the present application, a deduction system for parking coupons is provided.

[0024] A coupon acquisition module, configured to generate a first parking coupon according to the current available balance and the passenger flow, determine the first discount amount of the first parking coupon as the frozen amount, and freeze the frozen amount in the available balance;

[0025] A coupon identification module, configured to judge whether the first discount amount is greater than or equal to the first consumption amount of the target user in the parking lot when the target user uses the first parking coupon;

[0026] A coupon write-off module, configured to write off the frozen amount if the first discount amount is greater than or equal to the first consumption amount of the target user in the parking lot;

[0027] A coupon reissuance module, configured to reissue a second parking coupon according to the second consumption amount of the target user on the merchant side if the first discount amount is less than the first consumption amount of the target user in the parking lot.

[0028] In the third aspect of the present application, an electronic device is provided.

[0029] A deduction system for parking coupons, including a memory, a processor, and a program stored on the memory and executable on the processor, and the program can be loaded and executed by the processor to implement a deduction method for parking coupons.

[0030] In the fourth aspect of the present application, a computer-readable storage medium is provided.

[0031] A computer-readable storage medium stores a computer program, and when the computer program is executed by a processor, the processor implements a method for deducting parking coupons.

[0032] In summary, one or more technical solutions provided in the embodiments of the present application have at least the following technical effects or advantages:

[0033] 1. By intelligently determining the face value of the first-round parking coupons and freezing the corresponding amount, the present application realizes the precision of fund use, which not only meets the payment requirements for the first use but also prevents the risk of insufficient balance. After the user's consumption occurs, the system can check the actual amount deducted by the coupons to achieve accurate verification of the frozen amount, avoid duplicate or incorrect freezing of funds, and improve the fund use efficiency. When the first-round coupons cannot fully cover the user's parking fee, the system can quickly capture and obtain the user's remaining fee and issue a second-round supplementary coupon of the same amount. Through this technical solution, the coupons are distributed in a "use first and deduct later" manner, and the coupons are distributed and deducted according to the actual parking fee of the parking lot users. After deducting the parking fee, the un-deducted coupon amount can be recovered and returned to the merchant, enabling the parking lot property side to view more clearly the details of the coupon amount provided for the merchant, and the merchant to understand more clearly the actual deducted amount of the coupons, improving the data transparency of coupon distribution, achieving the effect of matching the coupon distribution amount with the actual parking fee and actual offset.

[0034] 2. By monitoring the balance usage of the merchant side in real time, when the available balance is lower than the preset security limit, the system can automatically obtain the remaining business hours of the merchant. Based on the remaining time, it can accurately predict the possible additional payment transaction amount within the current time period. The corresponding amount is extracted from the new transaction and replenished to the available balance of the merchant side. It realizes the dynamic monitoring of the balance usage and can actively and precisely replenish the balance, which not only ensures that the payment requirements in the subsequent time can be met but also avoids the situation of decreased fund utilization due to excessive freezing of funds. The active and intelligent balance replenishment method also reduces the manual operation cost. Merchants can rely on this intelligent balance replenishment mode to avoid the sudden shortage of balance when closing the store, ensuring the stable and efficient operation of the payment system and bringing a better consumer experience.

[0035] 3. By obtaining the specific issuance duration of the unwritten-off parking coupons, this application can identify the coupons that have exceeded the preset validity period and mark all these overdue coupons as invalid. For these invalid coupons, the corresponding amount freeze can be automatically lifted and returned to the available balance account on the merchant side. This can avoid the situation where funds are frozen for a long time but cannot be used, improving the efficiency of fund utilization. The increased available balance can support subsequent payment requirements and ensure the stable operation of the payment system. The returned frozen funds also facilitate the merchant's more refined monitoring and management of the available balance. Analyzing the data of unwritten-off coupons can also help the merchant evaluate and adjust the current coupon issuance strategy to improve the coupon issuance management level. This solution realizes the dynamic monitoring of the validity period of unwritten-off coupons, not only recovering resources and improving the utilization efficiency of coupons, but also significantly optimizing the allocation efficiency of funds on the merchant side and reducing the payment cost.

[0043] To facilitate the understanding of the method and system provided by the embodiments of the present application, before introducing the embodiments of the present application, the background of the embodiments of the present application will be introduced first.

[0044] Currently, the existing parking coupon distribution methods on the market mainly adopt the method of deducting first and then using. Since the actual deductible amount cannot be known, parking coupons are distributed in the form of inventory coupons. However, in the inventory coupon mode, without knowing the actual parking duration of the vehicle owner in advance, multiple types of coupons are distributed to the vehicle owner. The selling price of the coupon is not the actual deductible amount, but the parking lot estimates a unit price based on the parking situation for sale, resulting in the selling price of the coupon not being the actual deductible price, and the number of redeemed coupons not being the actual number of coupons to be redeemed. When distributing inventory coupons, n coupons can be distributed at one time. After the inventory coupons have been issued, the system cannot return the remaining undeducted coupons according to the actual number of redeemed coupons, which will lead to complaints from the parking lot property to the merchant. The reason is that the local billing method of the parking lot does not support the calculation of the actual deductible quantity of the coupon and the deductible amount returned for each undeducted coupon after the actual deduction of the coupon.

[0045] The embodiments of the present application disclose a method for deducting parking coupons. By obtaining the available balance and passenger flow of a merchant, a first parking coupon is initially generated, and the discount amount corresponding to the first parking coupon is frozen in the available balance. The discount amount is compared with the consumption amount of the actual parking lot, so as to conduct the verification of the available balance. It is mainly used to solve the problem that the coupon denomination does not match the actual parking fee.

[0046] After the above introduction of the background content, those skilled in the art can understand the problems existing in the prior art. Next, the technical solutions in the embodiments of the present application will be described in detail with reference to the accompanying drawings in the embodiments of the present application. The described embodiments are only a part of the embodiments of the present application, rather than all of the embodiments.

[0047] Referring to Figure 1 , a method for deducting parking coupons, the method includes S10 to S40, specifically including the following steps:

[0048] S10: Generate a first parking coupon based on the current available balance and the passenger flow, determine the first discount amount of the first parking coupon as the frozen amount, and freeze the frozen amount in the available balance.

[0049] The frozen amount refers to a certain amount frozen in the merchant's available balance, making this part of the frozen amount temporarily unavailable for other payment or cash withdrawal purposes. The value of the frozen amount is equal to the total face value of the first parking coupons distributed this time.

[0050] The first parking coupon refers to a coupon distributed by the merchant to the parking lot users for offsetting parking fees, including coupon types such as time-based coupons, amount-based coupons, full-free coupons, and multiple free-in-and-out coupons, etc. The multiple free-in-and-out coupon means that the vehicle owner can enter and exit the parking lot for free multiple times within a time period. In the original inventory mode (deduct first and then use), it is impossible to know how much parking fee the user will actually generate. After distributing the multiple free-in-and-out coupon, one multiple free-in-and-out coupon of the merchant is deducted, and only the fee of the unit price of the multiple free-in-and-out coupon is charged. The existing mode (use first and then deduct) is to calculate the total fee for the number of parking times of the vehicle within the time period and deduct the merchant's balance according to the fee amount. The full-free coupon means that all the fees for the vehicle owner's current parking are waived. In the original inventory mode (deduct first and then use), it is impossible to know how much parking fee the user will actually generate. After distributing the full-free coupon, the fee of one full-free coupon of the merchant is deducted. The existing mode (use first and then deduct) is to calculate the total fee for the number of parking times of the vehicle within the time period and deduct the merchant's balance according to the fee amount.

[0051] Specifically, to predict the total possible amount of parking coupons used on the current day, the parking lot charging software formats and reports the original operation data of each entity's parking lot to the platform, solving the problem in the current industry situation that it is impossible to know the actual deducted amount for "hourly coupons, full-free coupons, and multiple free entry coupons". Calculate the reasonable ratio of the predicted total usage amount to the current available balance, that is, determine the target ratio. The target ratio is to reasonably control risks and prevent the situation where the face value of the issued coupons is too large, resulting in insufficient available balance after use. The target ratio can be determined according to the business strategy of the merchant, for example, set at about 70%. Generate the first round of parking coupons based on the target ratio. Convert the available balance into the face value amount of parking coupons proportionally, and generate several first-round parking coupons with different face values. The property management side of the parking lot uniformly authorizes and opens different types of coupons that each merchant may actually use. After opening, the merchant can directly distribute the first-round parking coupons without limit when the available balance is recharged. Since the balance deduction mode is to deduct after use, it may lead to a negative balance in the merchant's balance wallet. To avoid this risk, the existing method of deducting after use is adopted. After each coupon is distributed, an amount will be frozen, and it will be thawed after the coupon is verified and written off, and the merchant's balance will be deducted. That is, when issuing the first round of parking coupons, determine the total face value as the frozen amount, and the frozen amount occupies the available balance. This can prevent the problem of negative available balance caused by repeated issuance. Through this step, the face value of the first round of parking coupons can be flexibly adjusted according to the actual situation on the current day, avoiding the problem of mismatch between the fixed face value and the actual situation, and at the same time, the risk can be controlled by freezing the amount to ensure the safety of the available balance.

[0052] In an optional embodiment of the present application, the specific process of determining the available balance of the merchant by the property management side includes: The merchant side collects the distribution data of historical parking coupons, including the distribution quantity and distribution amount, and the corresponding historical passenger flow data. The purpose of collecting these historical data is to help the property management side more accurately predict and allocate the available balance. The merchant side sends the collected data of the historical parking coupon distribution quantity, distribution amount, and the corresponding historical passenger flow to the property management side of the jurisdiction parking lot. The property management side has more information about the parking lot and the surrounding area. The property management side predicts the current suitable available balance of parking coupons for the merchant based on the historical data provided by the merchant and its own judgment of the passenger flow in this area. The basis for prediction is the correlation between the historical distribution amount and the passenger flow. The property management side feeds back the predicted available balance result to the merchant side, and the merchant side receives this available balance. In this way, the merchant side can obtain a relatively reasonable available balance amount for the subsequent generation of the first round of parking coupons. Through this step, the accuracy of the available balance amount can be improved, making the face value of the first round of parking coupons more in line with the actual needs, thereby improving the capital use efficiency and leaving room for subsequent reissuance.

[0053] Based on the above embodiments, the specific steps of the generation process of the first parking coupon include S11 to S12:

[0054] S11: Predict the consumption amount of the parking coupon according to the passenger flow, and determine the target ratio between the consumption amount of the parking coupon and the available balance.

[0055] Exemplarily, based on the historical passenger flow data in the past period of time in the area where the merchant is located, establish a correlation model between the passenger flow and the usage amount of the parking coupon. This is because there is a certain corresponding relationship between the two. Combining the real-time monitored passenger flow today and substituting it into the model for prediction, the total expected usage amount of the parking coupon today, that is, the consumption amount, can be obtained. The purpose of predicting the consumption amount is to reasonably plan the face value of the first round of coupons. Then, compare the predicted consumption amount with the available balance allocated by the property side, and calculate the reasonable ratio between the two, that is, the target ratio.

[0056] S12: Generate the first parking coupon according to the target ratio.

[0057] Exemplarily, the merchant side has predicted the total parking fee for the current period through the foregoing steps, and determined the reasonable ratio between the available balance and the total fee, that is, the target ratio. The merchant side divides the amount of the available balance according to the target ratio. For example, if the target ratio is 70%, then 70% of the available balance is taken to generate the face value amount. Generate several first-round parking coupons with different face values from the total face value amount obtained by the division. When determining the single face value of each coupon, the actual usage scenario should be considered, and the single face value should not be too large or too small. Distribute the already generated first-round parking coupons. Freeze the available balance amount corresponding to the face value of this batch of coupons to prevent the risk of unnecessary capital occupation caused by repeated distribution. By generating the first-round parking coupons according to the target ratio, the face value of the coupons can meet the current actual needs and take into account risk control, avoiding problems such as insufficient available balance or excessive coupon face value.

[0058] S20: When the target user uses the first parking coupon, determine whether the first preferential amount is greater than or equal to the first consumption amount of the target user in the parking lot.

[0059] Among them, the first consumption amount refers to the actual parking consumption amount of the target user in the parking lot when using the first-round parking coupon. That is, during the period when the target user parks in the parking lot, the parking service fee that should be paid according to the charging standard and parking duration of the parking lot.

[0060] Specifically, when the target user consumes parking services in the parking lot, they present the obtained first-round parking coupon for payment. The property side of the parking lot will read the face value information of the coupon, that is, the first preferential amount. The parking lot system reads the actual parking consumption amount of this user, that is, the first consumption amount. This amount is calculated based on the parking duration. Compare the first preferential amount with the actual parking consumption amount to determine whether the first preferential amount is greater than or equal to the first consumption amount. If the preferential amount is greater than or equal to the consumption amount, directly deduct the parking fee with the coupon. If the preferential amount is less than the consumption amount, a second-round parking coupon needs to be reissued to pay the remaining fee later. Through the judgment of this step, it can be distinguished whether the first-round coupon can fully pay the parking fee, so as to adopt different processing schemes such as making up the difference or directly deducting later to ensure the continuity of the user's parking fee payment.

[0061] S30: If the first preferential amount is greater than or equal to the first consumption amount of the target user in the parking lot, write off the frozen amount.

[0062] Specifically, when it is determined that the first preferential amount is greater than or equal to the first consumption amount of the target user. The face value of the first parking coupon will be directly used to deduct the parking fee expenditure of the target user to complete the payment. Automatically write off the part of the frozen amount that is equal to the actual deducted amount for this parking. That is, unfreeze it to make this part of the balance available again. When the platform receives the preferential write-off notice, the platform initiates a merchant balance deduction according to the actual preferential deducted amount. The platform will generate a detailed expenditure statement for each deduction. This statement will list in detail the usage of each coupon and the corresponding deducted amount, ensuring the clarity and traceability of the accounts. Merchants can view these statements at any time to understand the usage of coupons and the changes in the balance, improving the merchants' trust in the platform and reducing disputes caused by unclear accounts. The purpose of this operation is to accurately write off the corresponding frozen balance according to the actual usage of the coupon. Ensure that the frozen balance always reflects the latest status, provide a reference for subsequent balance scheduling, and also avoid the risk of capital occupation caused by repeated freezing or incorrect freezing. By writing off the frozen amount, the usage effect of the coupon can also be counted as a basis for the merchant to formulate marketing strategies.

[0063] Based on the above embodiments, the specific steps for writing off the frozen amount further include S31 to S32:

[0064] S31: Determine the amount difference between the frozen amount and the first consumption amount.

[0065] Exemplarily, after completing the payment with the coupon deducting the first consumption amount, obtain the first consumption amount data feedback by the parking lot system and the frozen amount data corresponding to the coupon. Compare the frozen amount data with the first consumption amount data, and calculate the numerical difference between the frozen amount and the first consumption amount, that is, the amount difference. If the frozen amount is greater than the first consumption amount, the difference is positive; if the frozen amount is less than the first consumption amount, the difference is negative. The purpose of calculating the amount difference is for subsequent balance processing to determine whether it is necessary to adjust the available balance for the difference. If there is a balance, it is necessary to unfreeze it back to the available balance; if there is a shortage, it is necessary to reissue the coupon from the merchant's new transaction order. By calculating the amount difference, the available balance and coupon reissue can be managed more precisely, ensuring the smooth operation of the payment system.

[0066] S32: In the frozen amount, return the amount difference to the available balance at the merchant end.

[0067] Exemplarily, after calculating the difference between the frozen amount and the first consumption amount, judge the positive or negative situation of the difference. If the difference is positive, it means there is a balance in the frozen amount that has not been used. At this time, it is necessary to unfreeze this part of the balance from the frozen amount and return it to the merchant's available balance account. Automatically unfreeze the funds equivalent to the difference part in the frozen amount, so that the funds of the difference part are restored to the available balance that can be freely used. The available balance increases by the corresponding difference, and the utilization rate of the merchant's account funds increases, which can be used for the subsequent second-round reissue or other purposes. Returning the balance is because the frozen amount is only used for risk control. If there is an actual surplus, it should be refunded to the merchant end to avoid long-term occupation of funds, and the coupon usage effect can also be counted by recovering the balance, providing a basis for the merchant to adjust the marketing strategy.

[0068] On the basis of the above embodiments, after completing the verification and cancellation of the frozen amount, when the available balance is insufficient, the specific steps for replenishing the available balance further include S321 to S322:

[0069] S321: Judge whether the available quota at the merchant end is less than the preset quota; if the available quota at the merchant end is less than the preset quota, obtain the remaining business hours of the merchant end on the same day.

[0070] Exemplarily, after returning the balance difference, it is determined whether the available balance of the current merchant terminal has fallen below the pre-set lower limit of the available balance. If the available balance has fallen below the preset limit, it indicates that there may be a risk of insufficient balance. At this time, it is necessary to obtain the remaining business hours of the merchant on the current date. Read the daily business hours arrangement of the merchant and calculate the remaining business hours from the current time until the closing time of the day. Obtaining this remaining business hours length is to predict the balance that may need to be replenished according to the length of time in the subsequent process to support the consumption demand during the continued business hours. Such an operation can intelligently monitor and give an early warning of the available balance of the merchant terminal, and make necessary replenishments in a timely manner according to the actual situation, so as to avoid the situation of being unable to pay due to insufficient balance during the business process.

[0071] S322: Predict the corresponding temporary replenishment amount according to the remaining business hours, and replenish the balance corresponding to the temporary replenishment amount to the available balance of the merchant terminal.

[0072] Exemplarily, obtain the remaining business hours length of the current merchant terminal. According to the historical transaction data of the merchant, calculate the average hourly transaction amount during this period. Multiply the hourly transaction amount by the remaining business hours to predict the total additional transaction amount during the remaining period. According to the set ratio of the available balance to the transaction amount, extract a part of the amount from the predicted total additional transaction amount as the available balance that needs to be temporarily replenished. Actually increase the calculated replenishment amount to the total current available balance of the merchant terminal to meet the subsequent transaction requirements. In this way, the available balance can be intelligently replenished according to the actual situation of the day to ensure that the merchant will not be unable to complete the transaction payment due to insufficient balance during the business hours. It avoids the problem of excessive balance that may be brought by fixed replenishment.

[0073] On the basis of the above embodiments, after the balance freezing operation is completed, when the available balance is insufficient and the parking coupon becomes invalid, the specific steps further include S323 to S324:

[0074] S323: Obtain the issuance duration of the unwritten-off parking coupons in the first parking coupon.

[0075] Exemplarily, after obtaining the total quantity information of the parking coupons issued in the first round, the quantity of the parking coupons that have been verified and used by users can be counted. By comparing the total quantity information of the issued parking coupons with the quantity of the parking coupons that have been verified and used by users, the quantity of the parking coupons that have not been verified and are still in the hands of users in the first-round issuance can be calculated. Query the specific issuance time of each unverified parking coupon, that is, the duration since the coupon was issued to the user. Obtaining the issuance duration of the unverified coupons is for subsequent judgment on whether these coupons have exceeded the validity period. If the coupons that have exceeded the validity period but have not been used can be retrieved, the corresponding frozen amount can be unfrozen and released, increasing the available balance. This can further improve the utilization efficiency of the frozen amount.

[0076] S324: Determine whether the issuance duration exceeds the preset validity period corresponding to the first parking coupon; if the issuance duration exceeds the preset validity period, mark the unverified parking coupon as invalid, and return the target amount corresponding to the unverified parking coupon to the available balance of the merchant side.

[0077] Exemplarily, after obtaining the specific issuance duration of each unverified parking coupon, the system compares these durations with the preset validity period of the coupons. If the issuance duration of a certain unverified coupon has exceeded the validity period of the coupon, it can be determined that the coupon has expired. Mark these unverified parking coupons determined to be expired as the expired status. Unfreeze the frozen amount corresponding to these expired unverified coupons, and return the amount to the available balance of the merchant side. The purpose of such an operation is to recycle the frozen amount that has exceeded the validity period and has not been used, avoiding the long-term freezing of funds without release. It reflects the problem of low utilization rate of some coupons, providing reference for merchants to formulate marketing strategies.

[0078] S40: If the first preferential amount is less than the first consumption amount of the target user in the parking lot, reissue the second parking coupon according to the second consumption amount of the target user on the merchant side.

[0079] Specifically, the second consumption amount refers to the consumption amount of the customer on the merchant side, which reflects the fees paid by the customer on the merchant side and is used to measure the standard for dispatching the second parking coupon.

[0080] Exemplarily, when the user pays the parking fee with the first-round parking coupon, if it is detected that the first-round discount amount of the user is less than the actual first consumption amount of the user in the parking lot, that is, the first-round discount cannot fully cover the user's current parking fee. To ensure that the user can smoothly complete the entire parking payment process, the system needs to obtain the second consumption amount of the user in this merchant, that is, the total actual consumption amount of the user in this merchant. After obtaining this true overall consumption scale of the user, the system can formulate a coupon reissue strategy based on this, judge the face value and match a suitable second-round parking coupon for reissue. Such precise reissue can avoid the interruption of the user's payment process and provide a better parking consumption experience. The reissue of the second parking coupon also gives the merchant an opportunity to contact the user again. This step formulates a targeted reissue strategy by learning about the user's overall consumption situation, which not only ensures the smooth payment of the user but also is conducive to the merchant's differential marketing.

[0081] On the basis of the above embodiments, the process of reissuing the second parking coupon specifically further includes S41 to S43:

[0082] S41: Determine the discount amount difference according to the parking coupon consumption amount and the first consumption amount.

[0083] Exemplarily, after the user pays the parking fee with the first-round parking coupon, the system needs to calculate and determine the difference between the two, that is, the discount amount difference, according to the parking coupon consumption amount of the user and the first actual consumption amount of the user in the parking lot. The purpose of calculating this discount amount difference is to analyze the usage situation and effect of the first-round parking coupon. By determining the size of the discount amount difference, the system can judge the coverage degree of the first-round parking coupon for the user's parking fee and whether there is still a balance unpaid after the user uses the first-round parking coupon. If the discount amount difference is positive, it means that the first-round parking coupon does not fully cover the user's parking fee; if the value is 0, it means that it just covers; if it is negative, it means that the coupon is overused. Obtaining the discount amount difference can help the system accurately judge the user's actual remaining parking fee, so as to quickly reissue a second-round parking coupon with a suitable face value. Based on the clear judgment of the discount amount difference, an accurate reissue of the face value of the second-round parking coupon can be made to ensure the continuity and smoothness of the user's parking fee payment, and also provide the merchant with an opportunity to better understand the user's needs and usage habits.

[0084] S42: Judge whether the discount amount difference is less than the preset amount difference; if the discount amount difference is less than the preset amount difference, reissue the second parking coupon corresponding to the discount amount difference.

[0085] Exemplarily, after calculating the difference in the user's preferential amount, the system needs to further determine whether this difference in preferential amount is less than a preset difference threshold. The reason for this step is that for the size of the difference in preferential amount, the strategy for reissuing the second-round parking coupon can be different, enabling refined management. If it is determined that the actual difference in the user's preferential amount is less than the preset difference, it indicates that after the user uses the first-round parking coupon, only a small amount of parking fees remain unpaid. In this case, the system can directly generate a second-round parking coupon with a face value equal to this value of the user's preferential amount difference and reissue it to the user. By adopting this direct equal-amount reissuing method, it can quickly and efficiently meet the user's payment needs for the small remaining parking fees, improve the user's parking consumption experience, reduce the complexity of system operation and resource allocation, and simplify the operation process. This step adopts different reissuing strategies according to the size of the preferential amount difference, achieving a highly targeted and efficient second-round parking coupon issuance, ensuring the integrity of the user's parking payment.

[0086] S43: If the difference in preferential amount is greater than the preset difference, then match the corresponding second parking coupon according to the second consumption amount.

[0087] Exemplarily, after determining that the difference in the user's preferential amount is greater than the preset difference, the system needs to obtain the user's second consumption amount at the merchant, that is, the user's total consumption amount. The reason for obtaining the second consumption amount is that when the difference in preferential amount is large, directly reissuing the second-round coupon equally may result in too much or too little reissued amount. Based on the user's second consumption amount, that is, their total actual consumption amount, perform big data analysis to match and reissue a second-round parking coupon with an appropriate face value. For example, a coupon with a face value equal to the difference between the second consumption amount and the first consumption amount can be reissued. When the difference in preferential amount is large, the system can reissue a second-round parking coupon with a reasonable face value by matching the second consumption amount. This can prevent the problem of the face value of the reissued coupon being too large or too small, truly meet the user's remaining payment needs, and at the same time improve the merchant's marketing efficiency. This step realizes a precise reissuing strategy when the difference in preferential amount is large, taking care of both user needs and increasing the merchant's marketing revenue.
