Detailed ways

The present application will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the related invention, but not to limit the invention. In addition, it should be noted that, for the convenience of description, only the parts related to the related invention are shown in the drawings.

It should be noted that the embodiments in the present application and the features of the embodiments may be combined with each other in the case of no conflict. The present application will be described in detail below with reference to the accompanying drawings and in conjunction with the embodiments.

The first, second, etc. numbers are only for distinction and have no other meaning.

FIG. 1 is a schematic flowchart of a payment exception processing method according to Embodiment 1 of the present invention. This method is applied in the scene of gas station refueling. The execution body of the method is a point of sale (Point of Sale, POS) server with a computing processing function. As shown in Figure 1, the method includes the following steps:

Step 110: Obtain the transaction mechanism of order payment according to the order of the refueling order generation operation, the inventory reduction operation, the initiating payment operation and the deduction operation; wherein, the refueling order generation operation, the inventory reduction operation, the initiating payment operation and the deduction operation are among the operations. each, as an atomic transaction.

Specifically, in the payment, you can refer to the transaction mechanism. Since the transaction has Atomicity, Consistency, Isolation, and Durability, multiple operations in a transaction are an inseparable As a whole, the entire transaction is committed only when all operations are successfully executed. A group of operations (multiple atomic transactions) within the same transaction must all succeed (or all fail); once the transaction is successfully committed, all transactions in the transaction All data operations must be persisted to the database.

As a result, multiple operations in the refueling payment process, in order, constitute a transaction mechanism for order payment. Among them, each operation can be used as an atomic transaction. Therefore, the problems in the order payment process are combined with the transaction mechanism to form a new mechanism, that is, the transaction mechanism of order payment.

In step 120, the transaction mechanism of order payment is stored.

For the set transaction mechanism of order payment, it can be stored in the server and set a fixed duration between each atomic transaction.

Step 130, when the next atomic transaction of the current atomic transaction is not received within the preset first time period, cancel the current previous atomic transaction.

Specifically, when the next operation is not received within the preset first time period, all previous operations can be cancelled, thereby avoiding the occurrence of repeated payments.

Specifically, this step can include the following three situations:

First, when the refueling order generation operation is performed and the inventory reduction operation is not performed, the refueling order information generated by the refueling order generation operation is cancelled.

Second, after the inventory reduction operation is performed, the initiating payment operation is not performed, the refueling order information generated by the refueling order generation operation and the inventory information generated by the inventory reduction operation are cancelled.

Third, when the payment operation is initiated and the deduction operation is not performed, the fueling order information generated by the fueling order generation operation, the inventory information generated by the inventory reduction operation, and the encrypted fueling order information generated by the payment operation are cancelled.

In one example, if an exception occurs in the "Inventory Reduction Operation -> Initiate Payment Operation" stage and the payment initiation fails due to an exception, according to the transaction mechanism of the order payment, the previous atomic transaction will be rolled back, that is, the reduced inventory recovery, The generated orders are voided, thereby avoiding abnormal situations such as abandoned orders and inventory error reduction caused by unpaid orders, and avoiding abnormal situations in the payment process.

Further, the application may also include the following steps before:

First, the refueling request message sent by the refueling equipment is received; the refueling request message includes the tag ID and the refueling equipment ID; then, according to the tag ID, the preset comparison table is queried to determine the target user account information corresponding to the tag ID; the target user account information includes refueling data; secondly, generate an authorized refueling message according to the refueling data; then, according to the refueling device ID, send the authorized refueling message to the refueling device corresponding to the refueling device ID; finally, after the refueling is completed, receive the refueling completion message sent by the refueling device .

Wherein, the gas station ID may include gas station ID and oil gun ID, the gas station ID may be the number of the gas station, and each gas station has a unique number. For example, the gas station number can be "1110".

The ID of the oil gun can include the number of the oil gun. The oil gun can be divided into oil guns with different numbers according to the corresponding gasoline model. For example, 001 can correspond to 92# gasoline, and 002 can correspond to 95# gasoline. One or more oil guns, when there are multiple oil guns, these oil guns can correspond to the same type of gasoline, or can correspond to different types of gasoline. The structure of the oil gun ID can be gas station ID + oil dispenser ID + oil gun number. For example, the meaning of "1110012001" can be: gas station number "1110", gas dispenser number "012", oil gun number "001", thus, Through the oil gun ID, you can get which oil gun under which fuel dispenser under the gas station.

In this application, the received refueling request message may be sent by the card reader on the fuel gun, or may be sent by the fuel dispenser. The tanker has a communication module and a processing module. The communication module in the tanker can transmit data with the server and the oil gun.

When the refueling request message is sent by the card reader on the fuel gun, the fuel gun of the gas station is provided with a card reader. The card reader includes a card reader, a communication module and a memory. The memory can store the gas station ID and the fuel gun. ID. The card reader can read the label on the fuel tank cover of the vehicle and decode it to obtain the label ID. The communication module in the fuel gun can package the label ID, the gas station ID in the memory and the fuel gun ID to generate a fueling request message. , sent to the server.

When the refueling request message is sent by the card reader on the fuel gun, the fuel gun of the gas station is provided with a card reader. The card reader includes a card reader and a communication module. The card reader can read the fuel tank cover of the vehicle. After the tag is decoded, the tag ID is obtained. The communication module in the oil gun can send the tag ID to the communication module in the tanker, and the processing module on the tanker packs the gas station ID, oil gun ID and tag ID to generate The refueling request message is sent to the server.

The tag may be a radio frequency identification (Radio Frequency Identification, RFID) tag.

A tag ID may correspond to a vehicle information, and the vehicle information includes a vehicle identification (Identity document, ID) and model information. The vehicle ID is the unique identification of the vehicle, which can be the license plate number or the globally unique number of the vehicle.

One tag ID corresponds to one vehicle information, and one user can have one or more vehicles, that is, one user can have one tag ID or multiple tag IDs, but one user only corresponds to one user account information. Thus, after receiving the refueling request message, the server unpacks the refueling request message, determines the user account information corresponding to the tag ID according to the tag ID, and uses the user account information corresponding to the current tag ID as the target user account information.

When there is pre-refueling order information to be paid in the target user account, the pre-refueling order information includes refueling data, and the server can send the refueling data to the refueling device to instruct the refueling device to refuel according to the refueling data.

The following steps may be included when establishing the pre-fuel order information to be paid:

First, receive the pre-refueling order information sent by the user terminal; the pre-refueling order information includes the user ID, the pre-refueling gas station ID, the pre-refueling oil gun ID, the pre-refueling liters and the pre-refueling consumption amount; then, according to User ID, query the credit capability information of the user account information corresponding to the user ID; the credit capability information includes the user's credit score; secondly, when the credit score is not less than the preset score threshold, query the user's payment account information corresponding to the user account information. The first payment capability information; finally, when the first payment capability information is not less than the pre-refueling consumption amount, the pre-refueling order information to be paid is generated.

The credit capability information may be a score of the user's credit capability. For example, the credit capability score may be generated according to the user's payment record and the customer's credit record. For example, the number of payments and the total amount in the server can generate a credit score, and the user's credit record in the bank generates a credit score. After the two credit scores are weighted and summed, the user's credit ability information can be obtained. The credit capability information is a dynamically changing data, which can be changed with the user's payment record and credit record.

Therefore, after reading the refueling data, the refueling device can refuel according to the refueling data, whereby the refueling machine is authorized to refuel. However, there may be a fault in the communication module of the refueling device later, which causes the problem that the refueling device cannot communicate with the server after the refueling device is refueled. In response to this problem, the server can perform the following steps:

First, when the refueling completion message sent by the refueling equipment is not received within the preset second time period, or, after receiving the refueling completion message, the refueling amount is calculated according to the refueling data, and the refueling amount is calculated according to the refueling data, the refueling amount, and the refueling equipment. ID, label ID and refueling time information, perform refueling order generation operation, and generate refueling order information; perform inventory reduction operation according to refueling data in the refueling order information, and obtain inventory information; then, after encrypting the refueling order information, initiate payment operation, send the encrypted refueling order information to a third-party server, so that the third-party server decrypts the encrypted refueling order information, performs a deduction operation, and generates refueling voucher information after the deduction operation; refueling voucher information; The information includes the actual payment amount and the payment account; finally, the refueling voucher information sent by the third-party server is received.

Therefore, when the communication module of the refueling equipment fails, the refueling information cannot be reported in time. At this time, the refueling equipment has been authorized to refuel, and the server does not receive the information fed back by the refueling equipment within a second period of time, such as 1 hour. , and subsequent payment operations can be performed automatically.

Among them, a combination of symmetric encryption and asymmetric encryption can be used for encryption. Correspondingly, the third-party server decrypts through the symmetric key, public key, and private key sent by the server in advance, thereby ensuring the security of the payment process.

By applying the payment exception processing method provided by the embodiment of the present invention, after the refueling device is authorized to refuel, if the communication module of the refueling device is faulty, the payment can be automatically deducted. And when there is no fault in the communication module of the refueling equipment, a transaction mechanism is introduced to form a new transaction mechanism for order payment. If there is an abnormality in the payment process, such as unsuccessful payment, repeated payment, etc., the transaction mechanism of order payment can be used. To process, avoid the occurrence of wrong payment such as double payment.
