Description

Technical Field

[0001] The present invention relates to the technical field of charging pile payment systems, and in particular to a payment terminal reconciliation processing system based on an energy storage charging pile. Background Art

[0002] With the booming development of the electric vehicle industry, charging stations, as key supporting facilities, are becoming increasingly important in urban transportation systems. Their stable and efficient payment settlement functions have become a core element in ensuring a positive charging experience for users, and regular reconciliation of payment terminals is crucial to ensuring accurate settlement.

[0003] Currently, the traditional payment terminals used in most charging stations on the market suffer from numerous drawbacks in reconciliation processing. Regarding network communications, traditional payment terminals rely on a network connection to a server for reconciliation, which not only consumes significant network resources but is also easily hindered by poor or unstable network signals, leading to delays or failures and severely impacting the operational efficiency of charging stations. Regarding manual operations, traditional reconciliation methods require manual intervention, making the entire process from data collection and collation to verification cumbersome and time-consuming. Manual operations inevitably carry the risk of error and fail to meet the stringent data accuracy and timeliness requirements of high-frequency charging station transactions. Furthermore, the user interface of traditional payment terminals is often poorly designed, with complex steps and a less-than-friendly interface. This results in a poor user experience and hinders the widespread adoption of electric vehicle charging services. Summary of the Invention

[0004] The embodiment of the present application provides a payment terminal reconciliation processing system based on an energy storage charging pile, which automatically reconciles the charging bill on time through the payment terminal of the charging pile, can comprehensively check the user's transaction data, effectively avoid settlement errors caused by various reasons, and ensure the accuracy of the transaction.

[0005] A payment terminal reconciliation processing system based on an energy storage charging pile, comprising:

[0006] The PT processing terminal is used for payment settlement of the charging pile, which includes a main controller, which is electrically connected to a signal receiving unit, a communication unit, and a storage unit through wires;

[0007] The HIM operation interface is a touch screen installed on the PT processing terminal. The HIM operation interface includes a processing unit, which is electrically connected to a signal output unit, a card reading unit, and an execution control unit through wires. The signal output unit is electrically connected to a signal receiving unit through wires, and the card reading unit is electrically connected to a card swiping unit through wires. The execution control unit is a charging gun control switch, and its number is equal to the number of charging guns. Each charging gun is connected in series with an execution control switch for turning the charging gun on or off.

[0008] Furthermore, a time setting unit is provided on the HIM operation interface. The time setting unit is electrically connected to the processing unit through a wire to facilitate the user to set the reconciliation time of the charging gun settlement information.

[0009] When the user uses the charging gun to settle the bill, the specific processing process of the PT processing terminal is as follows:

[0010] (1) Charging process: When a user uses a charging gun to charge, he first plugs the charging gun into the charging port of the electric vehicle, then selects the corresponding charging gun number on the HIM operation interface, and then swipes the credit card on the card swiping unit to pre-deduct the fee. After the pre-deduction is completed, click the corresponding execution control unit, and the system enters the charging process;

[0011] (2) Settlement process: When the user needs to end charging in advance, he / she selects the corresponding charging gun through the HIM operation interface again. At this time, the HIM operation interface automatically switches to the user card swiping interface to remind the user to swipe the card again;

[0012] (3) After the user swipes the card again, the card reader transmits the read card number information to the processing unit. The processing unit determines whether the read card number signal is consistent with the card number information during charging, and feeds back the judgment result to the HIM operation interface;

[0013] (4) If the processing unit determines that the charging is successful, the HIM operation interface switches to the charging end confirmation interface. After the user chooses to stop charging, the HIM operation interface feeds back the information to the processing unit, which controls the execution control unit to cut off the power of the charging gun. At the same time, the processing unit feeds back the settlement instructions used by the charging gun to the PT processing terminal through the signal output unit for fee settlement. After the settlement is successful, the PT processing terminal uses the communication unit to send the settlement output results to the user via email or Qrcode.

[0014] The specific operation process of further using the PT processing terminal to set the reconciliation time is as follows:

[0015] The user sets the reconciliation time via the time setting unit and waits for the set reconciliation time to arrive;

[0016] The processing unit sends a reconciliation instruction to the PT processing terminal via the signal output unit;

[0017] The PT processing terminal reconciles the bills. Since the PT processing terminal stores the transaction information of each charging, including the bill number, discharge amount, unit price, amount, etc.; if there are unsettled or abnormally settled bills, settlement will be carried out at this time.

[0018] One or more technical solutions provided in the embodiments of this application have at least the following technical effects or advantages:

[0019] 1. Automatically reconcile charging bills on time through the payment terminal of the charging station, which can comprehensively check the user's transaction data, effectively avoid settlement errors caused by various reasons, and ensure the accuracy of transactions.

[0020] 2. The payment terminal can record the user's charging information and transaction records in detail, providing rich data support for subsequent reconciliation processing, financial statistics and user data analysis, making it easier for operators to conduct refined management.

[0021] 3. The HIM operation interface is simple in design and easy to operate. It uses a touch screen and a reasonable functional layout to simplify the user's charging and settlement operation process and improve the user experience. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] Example 1

[0027] See also Figure 1 , a payment terminal reconciliation processing system based on energy storage charging pile, comprising:

[0028] The PT processing terminal is used for payment and settlement of charging piles. It includes a main controller, which serves as the main processing system. The main controller can use the microcontroller model "STM32F407ZGT6". This type of microcontroller has powerful data processing capabilities and rich peripheral interfaces, and can efficiently serve as the main processing system of the entire system; the main controller is electrically connected to the signal receiving unit, communication unit and storage unit through wires; the signal receiving unit can use the communication chip model "MAX485" to receive signals transmitted by external devices; the communication unit can use the wireless communication module model "ESP8266", which is responsible for data communication with external devices (such as user terminals) to realize the transmission of settlement results; the storage unit can use the chip model "AT24C02 EEPROM" to store the transaction information of each charging, including bill number, discharge amount, unit price, amount, etc., for subsequent reconciliation;

[0029] The HIM operation interface is a touch screen installed on the PT processing terminal. The HIM operation interface includes a processing unit. The processing unit can use a single-chip microcomputer model "MSP430F5529" and is mainly responsible for data processing; the processing unit is electrically connected to a signal output unit, a card reading unit and an execution control unit through wires. The card reading unit can use a radio frequency card reading module model "MFRC522", which can quickly and accurately read the user's card number information; the card reading unit is electrically connected to a card swiping unit through a wire. The card swiping unit uses a standard magnetic card or IC card swiping slot to facilitate user card swiping operations; the execution control unit is electrically connected to a charging gun through a wire for turning on the charging gun.

[0030] The signal output unit is electrically connected to the signal receiving unit through a wire. The signal output unit can use a transceiver with model "SN75HVD176" to receive the user's card swiping information and the status information of the charging gun and transmit it to the PT processing terminal.

[0031] The main controller will settle the fee based on the received information (user's card swiping information and charging gun status information) according to the signal transmitted by the processing unit. After the settlement is successful, the communication unit will use the settlement output result to send to the user via email or Qrcode.

[0032] The execution control unit is the charging gun control switch. You can use solid-state relays with the model "SSR-10DA". The number of solid-state relays is equal to the number of charging guns. Each charging gun is connected in series with an execution control switch to turn the charging gun on or off.

[0033] The charging guns are numbered according to quantity, and the number information is displayed on the HIM operation interface to facilitate users to select the charging gun for charging.

[0034] When a user uses a charging gun to settle a bill, the specific processing process of the PT processing terminal is as follows:

[0035] (1) Charging process: When a user uses a charging gun to charge, he first plugs the charging gun into the charging port of the electric vehicle, then selects the corresponding charging gun number on the HIM operation interface, and then swipes the credit card on the card swiping unit to pre-deduct the fee. After the pre-deduction is completed, click the corresponding execution control unit, and the system enters the charging process;

[0036] (2) Settlement process: When the user needs to end charging in advance, he / she selects the corresponding charging gun through the HIM operation interface again. At this time, the HIM operation interface automatically switches to the user card swiping interface to remind the user to swipe the card again;

[0037] (3) After the user swipes the card again, the card reader transmits the read card number information to the processing unit. The processing unit determines whether the read card number signal is consistent with the card number information during charging, and feeds back the judgment result to the HIM operation interface;

[0038] (4) If the processing unit determines that the charging is successful, the HIM operation interface switches to the charging end confirmation interface. After the user chooses to stop charging, the HIM operation interface feeds back the information to the processing unit, which controls the execution control unit to cut off the power of the charging gun. At the same time, the processing unit feeds back the settlement instructions used by the charging gun to the PT processing terminal through the signal output unit for fee settlement. After the settlement is successful, the PT processing terminal uses the communication unit to send the settlement output results to the user via email or Qrcode.

[0039] The HIM operation interface is also equipped with a time setting unit, and a clock chip model "DS1302" can be selected. The time setting unit is electrically connected to the processing unit through a wire to facilitate users to set the reconciliation time of the charging gun settlement information.

[0040] When the user clicks to stop charging, if the transaction settlement fails due to network problems, or if the charging is stopped but settlement is not completed normally due to a fault during the charging process, continuing to make new transactions at this time will lead to inaccurate settlement of subsequent transactions. To avoid this situation, the user can set a reconciliation time through the PT processing terminal. Automatic reconciliation through the PT processing terminal can avoid charging settlement errors. The specific operation process for setting the reconciliation time using the PT processing terminal is as follows:

[0041] The user sets the reconciliation time via the time setting unit and waits for the set reconciliation time to arrive;

[0042] The processing unit sends a reconciliation instruction to the PT processing terminal via the signal output unit;

[0043] The PT processing terminal reconciles the bills. Since the PT processing terminal stores the transaction information of each charging, including the bill number, discharge amount, unit price, amount, etc.; if there are unsettled or abnormally settled bills, settlement will be carried out at this time.

[0044] If a transaction fails to settle due to a network failure at the end of charging, the user can set a reconciliation time using the time setting unit on the HIM interface. For example, if the user sets reconciliation for 12:00 PM that evening, when the set reconciliation time arrives, the processing unit sends a reconciliation instruction to the PT processing terminal via the signal output unit. After receiving the instruction, the PT processing terminal processes unsettled or abnormally settled bills based on the transaction information stored in the storage unit to ensure the accuracy of charging settlement.

[0045] The technical solutions in the above-mentioned embodiments of the present application have at least the following technical effects or advantages: the charging bills are automatically reconciled on time through the payment terminal of the charging pile, which can comprehensively check the user's transaction data, effectively avoid settlement errors caused by various reasons, and ensure the accuracy of the transaction; the payment terminal can record the user's charging information and transaction records in detail, providing rich data support for subsequent reconciliation processing, financial statistics and user data analysis, and facilitating the operator to carry out refined management; the HIM operation interface is simple in design and easy to operate, and adopts a touch screen and a reasonable functional layout to simplify the user's charging and settlement operation process and improve the user experience.

[0046] The foregoing description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Various modifications and variations are readily apparent to those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
