Detailed Description
The present application is described in further detail below with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the invention and are not limiting of the invention. It should be noted that, for convenience of description, only the portions related to the present invention are shown in the drawings.
It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other. The present application will be described in detail below with reference to the accompanying drawings in conjunction with embodiments.
The first, second, etc. numbers are merely distinguished and have no other meaning.
Fig. 1 is a flowchart of a payment anomaly handling method according to an embodiment of the present invention. The method is applied to a scene of filling oil in a filling station. The execution subject of the method is a Point of sale (POS) server with a calculation processing function. As shown in fig. 1, the method comprises the steps of:
step 110, obtaining a transaction mechanism of order payment according to the sequence of the oiling order generation operation, the inventory reduction operation, the payment initiation operation and the deduction operation; wherein each of the fueling order generation operation, the inventory reduction operation, the initiate payment operation, and the deduction operation is as one atomic transaction.
Specifically, in payment, a transaction mechanism may be cited, and since a transaction has Atomicity (atom), consistency (Consistency), isolation (Isolation), persistence (Durability), a plurality of operations in the transaction are an integral atomic unit, only if all operations are executed successfully, the whole transaction is submitted, and a group of operations (a plurality of atomic transactions) in the same transaction must all succeed (or all fail); once a transaction commits successfully, all data operations in the transaction must be persisted into the database.
Thus, a plurality of operations in the fueling payment process are sequentially formed into a transaction mechanism for order payment. Wherein each operation can be an atomic transaction. Thus, the problems in the order payment process are combined with the transaction mechanism, thereby forming a new mechanism, namely the transaction mechanism of order payment.
Step 120, storing a transaction mechanism for order payment.
For a transaction mechanism for a set order payment, it may be stored in a server and a fixed time period between each atomic thing is set.
And 130, when the next atomic transaction of the current atomic transaction is not received within the preset first duration, the current previous atomic transaction is revoked.
Specifically, when the next operation is not received within the preset first duration, the current previous operation can be cancelled, so that the occurrence of repeated payment is avoided.
Specifically, this step may include the following three cases:
first, when the stock reduction operation is not performed after the fueling order generating operation is performed, the fueling order information generated by the fueling order generating operation is revoked.
Second, when the stock-reducing operation is performed, the payment initiation operation is not performed, and then the fueling order information generated by the fueling order generation operation and the stock information generated by the stock-reducing operation are cancelled.
Thirdly, when payment operation is initiated and payment deduction operation is not executed, the oiling order information generated by the oiling order generation operation, the inventory information generated by the inventory reduction operation and the encrypted oiling order information generated by the payment operation are withdrawn.
In one example, if the payment initiation fails due to the exception occurring in the "inventory reduction operation- > payment initiation operation" stage, according to the transaction mechanism of the order payment, the atomic transaction before that will be rolled back, i.e. reduced inventory is restored, the generated order is invalidated, so that the occurrence of abnormal situations such as waste order and inventory error reduction caused by the unpaid order is avoided, and the abnormal situation in the payment process is avoided.
Further, the method can further comprise the following steps:
firstly, receiving a refueling request message sent by a refueling device; the fueling request message includes a tag ID and a fueling device ID; then, inquiring a preset comparison table according to the tag ID, and determining target user account information corresponding to the tag ID; the target user account information includes fueling data; secondly, generating an authorized refueling message according to the refueling data; then, according to the oiling device ID, sending an authorized oiling message to the oiling device corresponding to the oiling device ID; and finally, after the oiling is completed, receiving an oiling completion message sent by the oiling device.
The fueling device IDs may include a fueling station ID and a fueling gun ID, and the fueling station ID may be a number of fueling stations each having a unique number. For example, the gas station number may be "1110".
The oil gun ID may include the number of the oil gun, and the oil gun may be divided into oil guns with different numbers according to the corresponding gasoline types, for example, 001 may correspond to 92 # gasoline, 002 may correspond to 95 # gasoline, and each oiling machine may have one or more oil guns, where when there are multiple oil guns, these oil guns may correspond to the same type of gasoline, and may also correspond to different types of gasoline. The structure of the gun ID may be a gas station id+a fuel dispenser id+a gun number, for example, "1110012001" may mean: by the gas station number "1110", the fuel dispenser number "012", and the gun number "001", it is possible to obtain which gun is located under which fuel dispenser in the gas station by the gun ID.
In this application, the received fueling request message may be sent by a card reader device on the fuel gun or by the fuel dispenser. The oiling machine is provided with a communication module and a processing module. The communication module in the oiling machine can carry out data transmission with the server and the oil gun.
When the oil filling request message is sent by the card reader on the oil gun, the card reader is arranged on the oil gun of the oil filling station, and the card reader comprises a card reader, a communication module and a memory, wherein the memory can store the ID of the oil filling station and the ID of the oil gun. The card reader can read and decode the label on the oil tank cover of the vehicle to obtain the label ID, and the communication module in the oil gun can package the label ID, the gas station ID in the memory and the oil gun ID to generate an oil filling request message and send the oil filling request message to the server.
When the oiling request message is sent by the card reader on the oil gun, the card reader is arranged on the oil gun of the gas station and comprises a card reader and a communication module, the card reader can read and decode a label on the oil tank cover of the vehicle to obtain a label ID, the communication module in the oil gun can send the label ID to the communication module in the oiling machine, and the processing module on the oiling machine packages the oiling request message generated by the oil station ID, the oil gun ID and the label ID and sends the oiling request message to the server.
Wherein the tag may be a radio frequency identification (Radio Frequency Identification, RFID) tag.
One tag ID may correspond to one piece of vehicle information including a vehicle identification (Identity document, ID) and vehicle type information. The vehicle ID is a unique vehicle identifier, which may be a license plate number or a globally unique number of the vehicle.
One tag ID corresponds to one piece of vehicle information, and one user may have one or more vehicles, that is, one user may have one tag ID or may have a plurality of tag IDs, but one user corresponds to only one piece of user account information. Therefore, after receiving the oiling request message, the server unpacks the oiling request message, determines the user account information corresponding to the tag ID according to the tag ID, and takes the user account information corresponding to the current tag ID as target user account information.
When there is pre-fueling order information to be paid under the target user account, the pre-fueling order information including fueling data therein, the server may send fueling data to the fueling device to instruct the fueling device to fueling in accordance with the fueling data.
When establishing the pre-fueling order information to be paid, the method may comprise the steps of:
firstly, receiving pre-fueling order information sent by a user terminal; the pre-fueling order information includes a user ID, a pre-fueling station ID, a pre-fueling gun ID, a pre-fueling liter, and a pre-fueling spending amount; then, inquiring credit capability information of user account information corresponding to the user ID according to the user ID; the credit ability information includes a credit score of the user; secondly, inquiring first payment capability information of a payment account of a user corresponding to user account information when the credit score is not smaller than a preset score threshold value; finally, when the first payment capability information is not less than the amount of consumption of the pre-fueling, pre-fueling order information to be paid is generated.
The credit ability information may be a score of the credit ability of the user, for example, the credit ability score may be generated according to a payment record of the user and a credit record of the client. For example, in the server, the payment times, total amount, etc. may generate a credit score, and the credit record of the user at the bank may generate a credit score, and after the two credit scores are weighted and summed, the credit capability information of the user may be obtained. The credit ability information is a dynamically changing data that can be changed with the user's payment record and credit record.
Thus, the fueling apparatus can perform fueling according to the fueling data after reading the fueling data, whereby the fueling machine is given fueling authorization. However, there may be a problem that the communication module of the fueling apparatus is failed later, resulting in failure of the fueling apparatus to communicate with the server after fueling of the fueling apparatus. For this problem, the server may perform the following steps:
firstly, when a refueling completion message sent by a refueling device is not received within a preset second duration, or after the refueling completion message is received, calculating a refueling amount according to refueling data, and performing a refueling order generation operation according to the refueling data, the refueling amount, a refueling device ID, a tag ID and refueling time information to generate refueling order information; according to the oiling data in the oiling order information, inventory reduction operation is carried out, and inventory information is obtained; then, after the oil filling order information is encrypted, a payment operation is initiated, the encrypted oil filling order information is sent to a third party server, so that the third party server decrypts the encrypted oil filling order information, then a deduction operation is carried out, and after the deduction operation, oil filling evidence information is generated; the oiling certificate information comprises actual payment amount and payment account; and finally, receiving the oiling certificate information sent by the third-party server.
Therefore, when the communication module of the oiling device fails, the oiling information cannot be reported timely, and at this time, the oiling device is authorized to be oiled, and when the server does not receive the information fed back by the oiling device within a second period of time, for example, within 1 hour, the server can automatically perform subsequent payment operation.
Wherein, the encryption can adopt a combination of symmetric encryption and asymmetric encryption. Correspondingly, the third party server decrypts the symmetric key, the public key and the private key which are sent in advance by the server, so that the safety of the payment process is ensured.
By applying the payment exception handling method provided by the embodiment of the invention, after the oiling equipment is authorized to be oiled, if the communication module of the oiling equipment has a fault, automatic deduction can be performed. And when the communication module of the oiling equipment has no fault, a transaction mechanism is introduced to form a new transaction mechanism for order payment, and if the payment process has abnormality, such as unsuccessful payment, repeated payment and the like, the transaction mechanism for order payment can be utilized for processing, thereby avoiding the occurrence of error payment such as repeated payment and the like.

according to the oiling data in the oiling order information, inventory reduction operation is carried out, and inventory information is obtained;
after the oiling order information is encrypted, a payment operation is initiated, the encrypted oiling order information is sent to a third party server, so that the third party server decrypts the encrypted oiling order information, then a deduction operation is carried out, and after the deduction operation, oiling evidence information is generated; the oiling certificate information comprises actual payment amount and payment account;
