Hereinafter, the present disclosure will be described in detail with reference to the drawings and in conjunction with the embodiments.

Figure 1 provides a transaction method applied to a gateway device. Figure 2 provides a transaction method applied to the payment platform. Figure 3 provides a transaction method applied to merchant equipment. Figure 4 is a complete transaction flow chart based on the gateway device payment platform, merchant device, and other surrounding platforms and devices.

In the present disclosure, the first device refers to a device that interacts with a merchant's device and generates payment requirements. The first device is, for example, an electric vehicle that requires a charging service, a mobile phone that requires a charging service, and the like. After the charging is completed, the holder of the first device needs to pay for this. Of course, in the embodiment of the present disclosure, this payment behavior may be automatically completed. Of course, the payer may also be the owner of the merchant's device. Merchant equipment refers to equipment that provides valuable services for the first device or accepts valuable services provided by the first device. The merchant device communicates with the gateway device. Merchant equipment is, for example, charging piles that provide charging services for electric vehicles or mobile phones. In addition to basic routing functions, gateway devices also have certain computing capabilities. The gateway device is, for example, an edge computing gateway or a fog computing gateway. The security platform refers to a platform that provides security services, such as a server for the distribution of secret keys. The operating platform refers to the management back office that manages the equipment of each merchant. The operation platform is, for example, a charging pile background management platform.

The following introduces the transaction process from the perspective of gateway equipment, payment platform and merchant equipment, and introduces the transaction method provided by the present disclosure from the perspective of gateway equipment, payment platform and merchant equipment and combined with specific transaction scenarios.

Referring to Fig. 1, the transaction method applied to the gateway device includes the following steps. From a device perspective, the execution subject of the transaction method is the gateway device. From a program perspective, the execution subject of the transaction method is the program carried on the gateway device.

S101. Obtain identification information and transaction information of the first device from the merchant device.

S102. Generate an order according to the identification information and the transaction information, where the order includes the identification information.

S103. Send the order to a payment platform, so that the payment platform can parse out the identification information of the first device from the order, and the identification information of the first device is compared with a payment platform on the payment platform. In the case of accounts being linked, operations are performed on the accounts.

The gateway device has the role of a POS machine (point of sale information management system) in the context of the Internet of Things. The gateway device communicates with the merchant device and the payment platform respectively. If the first device has a consumption behavior or provides a valuable service for the merchant's device, the first device will inevitably establish a communication connection with the merchant's device. In the Internet of Things scenario, the merchant device provides a valuable service for the first device or accepts the valuable service provided by the first device, and the merchant device can also determine the identification information of the first device. Therefore, during the communication between the gateway device and the merchant device, the gateway device can determine the identification information and transaction information of the first device (for example, including the amount of money consumed by the holder of the first device).

Step S102 is preferably executed in a trusted execution environment. In this way, safety can be improved. In addition to the identification information of the first device, the order usually contains other information, such as the account or merchant number of the manager (operating platform) of the merchant's device, the amount of the transaction, and whether the merchant's device is the payer or the receiver, etc. . The merchant number of the manager of the merchant device can be recorded in the gateway device when the connection between the gateway device and the merchant device is established. The transaction amount may be sent by the merchant device to the gateway device, or the merchant device may send the transaction amount to the gateway device, and the gateway device calculates the specific transaction amount. Here, the identification information of the first device replaces the account of the holder of the first device usually in an order.

Take the scenario where an electric vehicle is charged at a charging pile as an example. The battery management system (BMS, battery management system) in electric vehicles stores battery information (such as voltage, current, temperature), and also stores vehicle information (such as VIN number, which is also called Vehicle Identification Number), After the charging gun is inserted into the car, the charging pile can read the information (battery management system message) in the BMS system through the car's controller area network bus (CAN bus). By deploying an edge computing gateway at the charging station, use a network cable to connect it to the charging pile. The charging pile further sends the battery management system message to the edge computing gateway. The edge computing gateway can parse the battery management system message and extract the VIN number of the electric vehicle from it. In this way, the identification of electric vehicles is realized. The operating logic of the charging pile itself is relatively simple, with minor changes on the side of the charging pile.

Of course, the charging pile can also send the identification information of the electric vehicle to the edge computing gateway in an encrypted manner.

In addition, the edge computing gateway can receive the power consumption status submitted by the charging pile and calculate the fee to be paid (of course, it can also be that the charging pile itself calculates the consumption amount and submits the consumption amount to the edge computing gateway). The edge computing gateway encapsulates the VIN number, charging settlement information, and merchant information provided by the charging pile management service platform (of course, the merchant information can also be pre-stored in the edge computing gateway) into an order and sends it to the payment platform to complete the payment. In addition to the vehicle identification code VIN, the identification information of other electric vehicles such as the license plate number and radio frequency identification mark of the electric vehicle can also be read by the merchant's equipment.

The gateway device completes the collection of order-related information and generates the order, and then completes the payment transaction on the payment platform. The account of the holder of the first device in the order is replaced with the identification information of the first device. This makes the user's consumption process more convenient and faster, and realizes non-inductive payment. Since the gateway device can determine the identity of the first device through technical means, and can also determine the identity of the merchant device, this is conducive to the payment platform to accurately determine the transaction scenario.

In some feasible implementation manners, the process of the gateway device determining the identification of the first device and the consumption amount includes the following steps.

S1011. Perform key negotiation with the first device through the forwarding of the merchant device.

S1012. Receive a ciphertext of the identification information of the first device from the merchant device, where the ciphertext of the identification information of the first device is encrypted by the first device;

S1013. Parse the ciphertext into plaintext.

S1014. Receive the transaction information from the merchant equipment.

In this way, as the key information in the order, the first device sends its identification information to the merchant device in an encrypted manner, and then the merchant device sends it to the gateway device. The gateway device collects the identification information of the first device in a more secure manner.

In order to improve the security of information when the gateway device determines the identity of the first device, the gateway device performs ciphertext communication with the first device. For this reason, a key negotiation needs to be carried out between the gateway device and the first device.

The following is a feasible implementation for key negotiation between the gateway device and the first device. The security platform needs to provide the service of key distribution for the first device and the gateway device. It is necessary to set the security platform to send the first secret key and secret key identifier to the first device. The first secret key is used for encrypted communication between the first device and the gateway device. There is a one-to-one correspondence between the secret key identifier and the first secret key. The process includes the following steps.

S10111. Receive a secret key identifier from the merchant device, where the secret key identifier is a secret key identifier sent by the security platform to the first device and sent by the first device to the merchant device.

S10112. Send the secret key identifier to the security platform.

S10113. Obtain a first secret key corresponding to the secret key identifier from the security platform, where the first secret key is a secret key sent by the security platform to the first device.

In this way, the gateway device obtains the first secret key through the secret key identifier, and can realize peer-to-peer encrypted communication with the first device. Since the same first device may encounter many gateway devices, the same gateway device may encounter many first devices. The key distribution method of peer-to-peer encryption is more efficient.

Of course, after the identification information of the first device is determined, the first device may not be eligible for consumption on the merchant device (for example, the user of the first device is not a registered member).

To this end, in some feasible implementation manners, the transaction method further includes the following steps.

First, the identification information of the first device is sent to the operating platform to verify the availability of the identification information of the first device; then, when the identification information of the first device is available, the merchant is notified The device provides services for the first device.

If the identification information of the first device is unavailable, a message can be sent to the merchant device so that the merchant device rejects this consumption request or displays information on the merchant device to prompt the consumer how to operate.

The embodiments of the present disclosure also provide a transaction method applied to a payment platform, which includes the following steps.

S201: Establish an association between the identification information of the first device and the account.

S202. Receive an order from the gateway device, where the order includes identification information of the first device.

S203: In a case where the identification information of the first device is associated with an account on the payment platform, an operation is performed on the account.

The user needs to complete the association between his first device and his account on the payment platform in advance. After receiving the order, the payment platform can determine the corresponding account according to the identification information of the first device. The initiation of payment does not require manual operation by the user. If the account is opened for password-free payment in the payment system, the payment process does not require manual operation by the user. The payment platform can determine in which gateway device the payment scenario was initiated, so that the transaction scenario can also be determined.

Referring to FIG. 3, an embodiment of the present disclosure provides a transaction method applied to merchant equipment. The transaction method includes the following steps.

S301: Establish a communication connection with the first device.

S304: Determine identification information of the first device and corresponding transaction information.

S305. Send the identification information of the first device and the corresponding transaction information to the gateway device.

Based on the communication between the first device and the gateway device based on the Internet of Things, the merchant device can not only realize sensorless payment, but also help the payment platform to determine the transaction scenario.

In some optional implementation manners, the identification information of the first device is a ciphertext, and the following steps are further included before the identification information of the first device and the corresponding transaction information are sent to the gateway device.

S302. Receive a secret key identifier from the first device, where the secret key identifier is a secret key identifier sent by the security platform to the first device.

S303. Send the secret key identifier to the gateway device, so that the gateway device can obtain a corresponding first secret key according to the secret key identifier, where the first secret key is sent to the first secret key by the security platform. The secret key of the device.

That is, the merchant device forwards the secret key identifier to the gateway device, so that the gateway device can obtain the first secret key accordingly. Therefore, the gateway device and the first device perform symmetric encryption communication based on the first secret key.

Based on the above, the present disclosure also provides a transaction method, referring to FIG. 4, which includes the following steps.

S401. At the gateway device, receive the identification information and transaction information of the first device from the merchant device.

S402. In the gateway device, an order is generated according to the identification information and the transaction information, and the order includes the identification information.

S403. At the gateway device, send the order to a payment platform.

S404. Establish an association between the identification information of the first device and the account on the payment platform.

S405. On the payment platform, receive an order from the gateway device.

S406. In the payment platform, in the case where the identification information of the first device in the order is associated with an account on the payment platform, an operation is performed on the corresponding account.

Referring to Figure 5, the complete transaction process will be explained by taking the scenario of an electric vehicle charging at a charging pile as an example. When the charging gun is inserted into the charging port of the electric vehicle, the electric vehicle and the edge computing gateway establish communication through the charging pile, and negotiate the secret key. After the negotiation is completed, the secret key is used to encrypt the vehicle's VIN number. The charging pile reads the vehicle information through the car's CAN bus and sends the information to the edge computing gateway connected to it. After receiving the information, the edge computing gateway parses the message through the charging pile driver, and uses the first secret key to decrypt the VIN number, and then hand it over to the IoT payment platform to check the availability of the vehicle. If the electric vehicle has been bound to an account such as a bank card on the payment platform, the edge computing gateway controls the charging pile to charge the vehicle. When the charging is over and the charging gun is pulled out from the car charging port, the charging pile sends the vehicle information and the charging settlement information to the edge computing gateway. After the edge computing gateway recognizes the VIN number, the payment control encapsulates the VIN number and settlement information into The order is encrypted by the IoT security chip and submitted to the IoT payment platform to complete the payment.

In particular, taking charging piles and electric vehicles as examples, the interfaces and communication protocols between the two are standardized. There is no need to modify the existing electric vehicles and charging piles, and the construction cost of charging station operators is greatly reduced. The owner only needs to perform the actions of inserting and unplugging the charging gun to complete the initiation of charging and payment (or the entire process of payment).

The inventor of the present disclosure has discovered through research that the prior art center has the problem of low utilization rate of charging piles in scenarios such as charging piles scheduled for charging. For example, if a user makes an appointment to occupy a charging pile at 12:00-13:00, no matter whether the user actually comes to the charging pile to charge at 12:00-13:00, other users will not be able to use the charging station. pile. To solve this problem, the inventor of the present disclosure further proposes the following solution.

The merchant's equipment can be occupied by reservation, and the first device that can make an appointment within the reserved time period is allowed to be occupied by other first devices when the merchant device is not occupied, and the merchant equipment can be occupied by other first devices during the reserved time period. When the first device is occupied, the merchant device is released from the other first device's occupation of the merchant device according to the reservation certificate provided by the reservation user.

The reserved user here refers to the user who has reserved and occupied the charging pile.

For the gateway device, the transaction method further includes the following steps.

S104. Obtain reservation information from the operating platform, where the reservation signal includes: the identification information of the first device that makes the reservation and the reservation time period. The gateway device can obtain the reservation information from the operating platform, and of course, it can also obtain the reservation information from the merchant device. To ensure the safety and accuracy of information, it is preferable to obtain reservation information from the operating platform.

S105. In the reservation time period, obtain the identification information of the first device of the reserved user from the merchant device.

S106. Compare the identification information of the first device of the reserved user acquired from the operating platform with the identification information of the first device of the reserved user acquired from the merchant device, and notify if the comparison is successful The merchant device provides a service for the first device of the reserved user.

In this way, the gateway device completes the exclusive use of the merchant device for the reserved user during the reserved time period. Of course, if the merchant device was previously occupied by other first devices, the merchant device will terminate the service to the other first devices accordingly.

In conjunction with this, the following steps are also included in the transaction method of merchant equipment.

S306. In the reservation time period, receive the reservation voucher provided by the reservation user.

S307. Send the reservation voucher to the operating platform via the gateway device for verification.

S308. In the case that the reservation voucher is verified, the identification information of the first device of the reservation user is sent to the gateway device, so that the gateway device will receive the reservation user from the merchant device The identification information of the first device is compared with the identification information of the first device of the reserved user received from the operating platform.

S309. After receiving the successful comparison message sent by the gateway device, provide a service for the first device.

Taking the charging pile occupied by appointment as an example, the appointment process can be as follows.

After the charging pile is reserved, it can still provide charging services for non-reserved vehicles, but it will be notified before the non-reserved vehicle is charged: after the charging reservation time is reached, the charging pile of the vehicle may be preempted by the reserved vehicle. The so-called preemption means that the reserved user can terminate the charging of the non-scheduled vehicle during the scheduled charging time, and insert the charging gun into the reserved vehicle for charging.

The user selects the charging pile on the charging pile operating platform to make a charging reservation, and then the charging operator sends the last 4 digits of the user's mobile phone number (as a reservation voucher), vehicle VIN number and reservation time to the reservation service on the edge computing gateway. Arrive at the charging station within the scheduled time for charging. If the vehicle is using the charging station for charging at this time, the reserved user can enter the last 4 digits of the personal mobile phone number on the charging station screen to end the current charging, and then plug the charging gun into In your own vehicle. After plugging in the gun, the edge computing gateway compares the VIN number of the reserved service with the VIN number of the current vehicle. If they are consistent, the charging pile will be locked until the end of charging or the end of the appointment time. If they are inconsistent, they will not be charged.

Referring to Fig. 6, in a specific transaction scenario, some transaction processes can be performed in the following manner.

The information of each participant in the transaction scenario is as follows.

User A	Mobile number: P1111, bank card number: C621, own vehicle A
User B	Mobile phone number: P2222, bank card number: C622, own vehicle B
User C	Mobile phone number: P3333, bank card number: C623, own vehicle C
Vehicle A	VIN number: E1111
Vehicle B	VIN number: E2222
Vehicle C	VIN number: E3333
Charging pile A	Charging pile code: P1
Charging pile B	Charging pile code: P2

All users need to bind bank cards and vehicle VIN numbers on the payment platform. The merchant number of the charging pile operating platform is S1.

After the charging gun of the charging pile A is inserted into the vehicle A, the vehicle A requests the secret key identification from the security platform. The security platform generates the first secret key K and the secret key identification token, records them locally and sends them to the electric vehicle. After receiving, the electric vehicle sends the secret key identification token to the edge computing gateway through the charging pile, and the edge computing gateway sends the secret key identification token to the security platform. The security platform finds the corresponding first secret key K according to the secret key identifier token, and sends it to the edge computing gateway. The edge computing gateway obtains the secret key identification token. After that, the vehicle A uses the first key K to encrypt the VIN number. Charging pile A reads the encrypted vehicle VIN number, battery temperature, battery power and other information from the CAN bus of car A and sends it to the edge computing gateway. The edge computing gateway uses the first secret key K to decrypt and recognizes from the information that the VIN number of the charging vehicle is E1111, and sends it to the payment platform (usually also sent in an encrypted manner). After receiving the message, the payment platform decrypts it, and then queries whether the vehicle with the VIN number E1111 has been bound to a bank card, and the result is that it has been bound, and then informs the edge computing gateway through the network that it can charge. After the edge computing gateway receives the instruction that can be charged, it controls the charging pile A to start charging.

After vehicle A is charged, charging pile A reads the vehicle's VIN number, battery temperature, battery power and other information from the CAN bus of vehicle A, and sends it to the edge computing gateway along with the current power consumption of 20 kWh. The edge computing gateway calculates that the payment amount is 20 yuan according to the power consumption of 20 kWh, and recognizes that the VIN number of the charging vehicle is E1111, and then it is packaged into an order together with the charging pile operator's merchant number S1 and sent to the Internet of Things payment platform . After receiving the order, the payment platform finds the bank card C621 corresponding to the VIN number E1111, and then uses the payment channel to deduct 20 yuan from the bank card C621 to the merchant S1. After the deduction is over, the IoT payment platform will synchronize the deduction to the charging pile operation platform.

User C makes an appointment for charging on the charging pile operating platform, and the appointment content is from 8 to 10 o'clock, and vehicle C makes an appointment for charging on the charging pile B. After the appointment is successful, the charging pile operating platform will send the appointment time, vehicle C's VIN number E3333, and user D's mobile phone number P3333 to the appointment service on the edge computing gateway. Vehicle B uses charging pile B for charging at 7 o'clock. At this time, charging pile B informs user B through the charging pile screen that the pile has been scheduled for charging at 8 o'clock, and vehicle B's charging may be affected. For some reason, vehicle C arrives at the charging station at 8:30, while vehicle B is using charging pile B for charging. User C enters the last four digits 3333 of the mobile phone number on the charging pile screen, and the charging pile sends the last four digits 3333 of the mobile phone number to the edge computing gateway for verification. The reservation service program module on the edge computing gateway receives the request and performs the phone call Comparing the four digits after the number, it is found that they are the same, and then the charging pile B is controlled to end the charging. After charging, user C unplugs the charging gun from vehicle B, and then plugs it into vehicle C. After that, the edge computing gateway recognizes that the VIN number of the vehicle is E3333. At this time, the reserved vehicle VIN number stored in the reservation service of the edge computing gateway is also E3333, and the two are the same. The edge computing gateway controls the charging pile B to start charging the vehicle C.
