[0022] The embodiments of the present invention will be described below with reference to the accompanying drawings in the embodiments of the present invention.

[0023] Figure 1 Shows a flowchart of an offline and power-off order processing method for an AC charging pile provided by an embodiment of the present invention. As Figure 1 shown, the method includes the following steps 101-104.

[0024] Step 101: Trigger a data saving coroutine when the charging pile is offline or powered off.

[0025] As Figure 2 shown, Figure 2 Shows a detailed process schematic diagram of an embodiment of the present invention in practical applications. When the charging pile is offline or disconnected, a data saving coroutine is automatically triggered, that is, the process of offline saving of order data is entered.

[0026] Step 102: Query the database for orders that are being charged and determine whether the order is single-phase or three-phase.

[0027] Specifically, during the data saving process, it is possible to automatically query in the database of the charging pile system whether there is currently an order being charged. If so, it is determined whether the order is a single-phase charging order or a three-phase charging order.

[0028] Step 103: Store the current value in the offline folder as an offline record every first preset time, and the format of the offline record is a lightweight data interchange format.

[0029] Among them, the first preset time can be any time interval preset in advance. According to actual applications, the first preset time can be set to 60 seconds, that is, every 60 seconds, the current value (i.e., MeterValue) is automatically stored in the offline folder. It can be understood that this offline folder is located in the database. As Figure 2 shown, after determining whether the current charging order is single-phase or three-phase based on the above step 102, the single-phase MeterValue can be stored in the corresponding offline folder, and the three-phase MeterValue can also be stored in the corresponding offline folder as an offline record (such as start.metervalue.stop). It should be noted that the embodiment of the present invention adopts a lightweight data exchange format (i.e., json) as the format for storing offline records, which is convenient for subsequent uploading and processing.

[0030] For example, create a new offline file named with the local order number in the home / offlinedata directory and store the file content in json format.

[0031] Step 104: When the charging pile is online, upload an offline record every second preset time.

[0032] As Figure 2 shown, when the charging pile system is offline or disconnected, in addition to automatically triggering the data saving coroutine, a reconnection coroutine also needs to be started. As the name implies, the reconnection coroutine is a program for reconnection. If the charging pile is in an online state through the reconnection coroutine, the embodiment of the present invention needs to upload an offline record previously saved during the offline or power-off period every second preset time. Among them, based on actual usage, the second preset time can be set to 2 seconds, that is, upload an offline record every 2 seconds, so as to ensure that users can still charge normally in the case of offline or power-off, and supplement and report the order information to the platform after the network is restored.

[0033] Through the method for processing offline and power-off orders of the AC charging pile provided by the embodiment of the present invention, in the case of network interruption or limited Internet access environment, order information and charging data can be pre-stored and then reported to the platform after going online, ensuring the integrity and accuracy of the data and avoiding the loss of order information. Moreover, for data storage, the order information is saved in the form of local files, and the file content is stored in json format, which is convenient for subsequent uploading and processing. After the network is restored, the offline records can be uploaded at a certain time interval to ensure the timeliness and integrity of the data.

[0034] Optionally, as Figure 2As shown, the method further includes: a User Datagram Protocol coroutine, i.e., a UDP coroutine. In the embodiment of the present invention, by automatically starting the User Datagram Protocol coroutine in the case of offline or power-off, the status information of the order being charged can be saved to a status notification file, such as status_notifications.json. Optionally, the above status information at least includes: a status change parameter and an error code change parameter.

[0035] Optionally, step 104 "upload an offline record every second preset time" may include the following steps A.

[0036] Step A: Traverse the offline folder, and upload the offline records corresponding to the order numbers in descending order of the order numbers.

[0037] For multiple offline files existing in the offline folder, when it is necessary to upload offline records, the offline files corresponding to the order ids stored in the database can be traversed according to the order numbers (such as id numbers). For example, if there are two offline files with order ids 34 and 35 at this time, that is, metervalue34.json and metervalue35.json exist in home / offlinedata. Since the order with a larger id is the order closest to the current time, then, the offline file corresponding to order number 35 can be synchronized first, and then the offline file corresponding to order number 34 can be synchronized until all unsynchronized orders are processed. During the process of processing a single order, ensure that all information of start, metervalue, and stop is transmitted. If the transmission is not completed due to network disconnection, then continue the transmission after going online until all orders are transmitted.

[0038] Optionally, as Figure 2 shown, after step 104 "upload an offline record every second preset time" above, the method further includes the following steps B.

[0039] Step B: Determine whether there are unsynchronized orders in the offline folder; if so, continue to upload an offline record (such as start.metervalue.stop) every second preset time (such as 2 seconds), and delete the uploaded offline records in the offline folder. It should be noted that this step B can be set as a loop step, by repeatedly determining whether there are unsynchronized orders in the offline folder, executing the subsequent offline record upload steps, or ending the process.

[0040] In addition, if the network is restored and then disconnected again during the upload process, or a certain offline record upload fails, it remains in the offline folder. New offline records continue to be added later, and continue to be uploaded in sequence (in reverse order) after the network is restored.

[0041] Optionally, the method may further include the following step C.

[0042] Step C: If the internal data record in a single charging order file in the offline folder is full, delete the historical data with the earliest creation time in the internal data record of the charging order file; if the internal data record in the offline folder is full, delete the offline record corresponding to the charging order with the earliest creation time in the offline folder (such as offlinedata).

[0043] For example, the number of offline records that can be stored in the offline folder can be set to 500. After exceeding 500, the file with the farthest historical time, that is, the historical data with the earliest creation time, can be deleted.

[0044] In addition, as Figure 3 shown, the embodiment of the present invention also provides a specific flowchart to describe how the system performs different operations according to different conditions when processing offline files. This process mainly involves the check of transaction ID, order number, order synchronization status, and order status, and performs corresponding supplementary reporting operations according to different conditions. The specific process is as follows:

[0045] 1. Check whether the offline file exists: If the offline file does not exist, the process ends.

[0046] 2. Check whether the transaction ID and order number exist: If transactionID == 0 || CheckOrderNumberExists transactionID == false, the process ends. Among them, the TransactionId field: represents the order number responded by the platform after the charging pile synchronizes with the platform when the charging starts. CheckOrderNumberExists means: check whether the order number exists.

[0047] 3. Check the order synchronization status: If OrderSync == 0, the process ends. Among them, the OrderSync field is 1: represents that all information of this order has been synchronized to the platform. The OrderSync field is 0: represents that it has not been fully synchronized.

[0048] 4. Check if the transaction ID is 0: If TransactionId != 0, then check OrderStatus: If OrderStatus == 1, start the offline and online charging completion, report the supplementary start, and then start the offline and online charging completion, report the supplementary stop. Among them, the OrderStatus field represents that regardless of whether the pile is connected to the network, the local order charging is completed. If TransactionId == 0, then check OrderStatus: If OrderStatus == 1, start the offline and online charging in progress, report the supplementary start, and then start the offline and online charging in progress, report the power and status. If OrderStatus != 1, start the offline and online charging in progress, report the supplementary start, and then start the offline and online charging in progress, report the supplementary stop.

[0049] In addition, as Figure 4 shown, the embodiments of the present invention also provide specific flowcharts to describe the processing logic of the charging pile under different startup modes, including remote startup and local startup, as well as different processing flows in online and offline states. The specific process includes:

[0050] 1. Select the charging method: The user selects the charging method, which is divided into remote startup and local startup.

[0051] 2. Remote startup: Call RemoteStart (remote startup). If the charging pile is in the offline state: The platform responds with reject (reject), and the process ends. If the charging pile is in the online state: The platform responds with accept (accept), the charging pile terminal uploads Authorize (authorization), the platform responds with reject (reject), and the process ends; the platform responds with accept (accept). Start charging: The charging pile terminal sends StartTransaction.

[0052] 2. Local startup: The user selects plug-and-charge ("PLUG"), Bluetooth startup ("BLE"), charging point card swiping startup ("XXXX"), reservation charging ("PLAN" when starting). If the charging pile is in the offline state: Locally save Authorize (authorization), the charging pile starts directly, and locally save StartTransaction. If the charging pile is in the online state: Upload the locally saved offline data, that is, the charging pile terminal uploads Authorize (authorization), the platform responds with reject (reject), and the process ends; the platform responds with accept (accept), start charging: The charging pile terminal sends StartTransaction.

[0053] It can be understood that both remote startup and local startup involve the judgment of the online and offline states of the charging pile. In the online state, multiple responses and confirmations (accept) from the platform are required to start charging. In the offline state, the authorization information is locally saved and the data is uploaded after the charging pile goes online. When starting charging, the charging pile sends StartTransaction.

[0054] The above text has described in detail the method for processing offline and power-off orders of the AC charging pile provided by the embodiments of the present invention. This method can also be implemented by a corresponding device. Next, the device for processing offline and power-off orders of the AC charging pile provided by the embodiments of the present invention will be described in detail.

[0055] Figure 5 The structural schematic diagram of a device for processing offline and power-off orders of an AC charging pile provided by an embodiment of the present invention is shown. As Figure 5 shown, the device for processing offline and power-off orders of the AC charging pile includes a processor. The processor includes: a startup module 51, an order query module 52, a data saving module 53, and a data uploading module 54;

[0056] The startup module 51 is used to trigger a data saving coroutine when the charging pile is offline or powered off.

[0057] The order query module 52 is used to query the database for the orders that are being charged and determine whether the orders are single-phase or three-phase.

[0058] The data saving module 53 is used to store the current value into an offline folder as an offline record every first preset time, and the format of the offline record is a lightweight data exchange format.

[0059] The data uploading module 54 is used to upload one of the offline records every second preset time when the charging pile goes online.

[0060] Optionally, the device further includes: a User Datagram Protocol coroutine module; the User Datagram Protocol coroutine module is used to save the status information to a status notification file.

[0061] Optionally, the status information at least includes: a status change parameter and an error code change parameter.

[0062] Optionally, the data uploading module 54 includes: a traversing unit.

[0063] The traversing unit is used to traverse the offline folder and upload the offline records corresponding to the order numbers in descending order of the order numbers.

[0064] Optionally, the device further includes: an uploading module.

[0065] The uploading module is used to determine whether there are unsynchronized orders in the offline folder; if so, continue to upload one offline record every second preset time, and delete the uploaded offline records in the offline folder.

[0066] Optionally, the device further includes: a deletion module.

[0067] The deletion module is used to, if the internal data records in a single charging order file in the offline folder are full, delete the historical data with the earliest creation time in the internal data records of the charging order file; if the internal data records in the offline folder are full, delete the offline records corresponding to the charging order with the earliest creation time in the offline folder.

[0068] The device provided by the embodiment of the present invention can pre-store order information and charging data in the case of network interruption or limited Internet access environment, and then report them to the platform after going online, ensuring the integrity and accuracy of the data and avoiding the loss of order information. Moreover, for data storage, the order information is saved in the form of a local file, and the file content is stored in json format, which is convenient for subsequent uploading and processing. After the network is restored, the offline records can be uploaded at a certain time interval to ensure the timeliness and integrity of the data.
