[0079] Based on the above hardware structure, an embodiment of a method for synchronizing data between a retail terminal and a cloud is proposed.

[0080] Reference Figure 2 , Figure 2 Schematic diagram of the flow of the first embodiment of the data synchronization method between a retail terminal and the cloud of the present invention.

[0081] In a first embodiment, the data synchronization method between the retail terminal and the cloud comprises the following steps:

[0082] Step S10: Acquire the local data of the retail transaction to be synchronized in the terminal and the cloud data in the cloud.

[0083] It should be noted that the retail transactions to be synchronized are retail transactions that require data synchronization. The retail transactions to be synchronized have corresponding local data on the terminal, and the retail transactions to be synchronized have corresponding cloud data on the cloud.

[0084] Step S20: Compare and analyze the local data and the cloud data to obtain a comparison and analysis result.

[0085] It should be understood that by comparing and analyzing the local data and the cloud data, corresponding comparative analysis results can be obtained.

[0086] Step S30: When the comparison and analysis result shows that there is difference data, data synchronization is performed according to the difference data.

[0087] It is understandable that when there are difference data in the comparison file analysis result, data synchronization can be performed based on the difference data.

[0088] Through the above scheme, this embodiment obtains the local data of the retail transaction to be synchronized in the terminal and the cloud data in the cloud; compares and analyzes the local data and the cloud data to obtain a comparison analysis result; when the comparison analysis result shows that there is difference data, synchronizes the data according to the difference data, thereby ensuring the availability of the retail terminal, improving the data consistency and overall stability of the retail system in different network environments, ensuring the continuity and flexibility of data synchronization, and improving the speed and efficiency of data synchronization between the retail terminal and the cloud.

[0089] Further, Figure 3 FIG. 2 is a flow chart of a second embodiment of a method for synchronizing data between a retail terminal and a cloud in accordance with the present invention. Figure 3 As shown, a second embodiment of the data synchronization method between a retail terminal and a cloud of the present invention is proposed based on the first embodiment. In this embodiment, the step S10 specifically includes the following steps:

[0090] Step S11: retrieve the local database and local log file corresponding to the retail transaction to be synchronized from the terminal through the retail system, and generate local data according to the local database and the local log file.

[0091] It should be noted that the retail system can retrieve the local database and local log files corresponding to the retail transactions to be synchronized from the terminal, and then generate local data according to the local database and the local log files.

[0092] Furthermore, the step S11 specifically includes the following steps:

[0093] Retrieving the local database and local log files corresponding to the retail transactions to be synchronized from the terminal through the retail system;

[0094] The local log file and the file data in the local database corresponding to the local log file are used as local data.

[0095] It should be understood that the retail system can retrieve the local database and local log file of the corresponding retail transaction to be synchronized from the terminal, and then the local log file and the file data corresponding to the local log file in the local database can be used as local data.

[0096] Step S12: Retrieving the cloud database and cloud log file corresponding to the retail transaction to be synchronized from the cloud through the retail system.

[0097] It is understandable that the cloud database corresponding to the retail transaction to be synchronized is retrieved from the cloud by the retail system.

[0098] Step S13: Use the cloud log file and the file data in the cloud database corresponding to the cloud log file as cloud data.

[0099] It should be understood that the cloud log file and the file data in the cloud database corresponding to the cloud log file are regarded as cloud data.

[0100] Through the above scheme, this embodiment uses the retail system to retrieve the local database and local log files corresponding to the retail transactions to be synchronized from the terminal, and generate local data according to the local database and the local log files; retrieve the cloud database and cloud log files corresponding to the retail transactions to be synchronized from the cloud through the retail system; use the cloud log files and the file data corresponding to the cloud log files in the cloud database as cloud data; ensure the availability of the retail terminal, improve the data consistency and overall stability of the retail system in different network environments, and ensure the continuity and flexibility of data synchronization.

[0101] Further, Figure 4 FIG. 1 is a flow chart of a third embodiment of a method for synchronizing data between a retail terminal and a cloud in accordance with the present invention. Figure 4As shown, a third embodiment of the data synchronization method between a retail terminal and a cloud of the present invention is proposed based on the first embodiment. In this embodiment, the step S20 specifically includes the following steps:

[0102] Step S21, obtaining the current connection status between the terminal and the cloud.

[0103] It should be noted that the current connection state between the terminal and the cloud is obtained, and the current connection state machine terminal or the current connection state of the cloud includes the connection and disconnection states.

[0104] Furthermore, the step S21 specifically includes the following steps:

[0105] Acquire the terminal monitoring state of the terminal, and obtain the current connection state of the terminal according to the terminal monitoring state;

[0106] Performing heartbeat detection on the cloud, and comparing the number of heartbeat detections with a preset number;

[0107] When the number comparison result is that the number of heartbeat detections exceeds the preset number of times, determining that the current connection state of the cloud is an offline state;

[0108] When the comparison result of the number is that the number of heartbeat detections does not exceed the preset number, it is determined that the current connection state of the cloud is an online state.

[0109] It should be understood that after obtaining the terminal monitoring status of the terminal, the current connection status of the terminal can be obtained based on the terminal monitoring status; by performing heartbeat detection on the cloud, the current status of the cloud can be determined based on the heartbeat detection result.

[0110] In the specific implementation, when the connection with the cloud is disconnected, it will automatically switch to this mode, and all data changes will be recorded only in the local database; once the cloud connection is restored, the system will automatically return to online mode after data synchronization is completed; the cloud connection status is determined by the heartbeat detection mechanism, and it will be considered disconnected if the preset timeout number is exceeded.

[0111] Step S22: Compare and analyze the local data and the cloud data according to the current connection status to obtain a comparison and analysis result.

[0112] It is understandable that the local data and the cloud data may be compared and analyzed according to the current connection status to obtain corresponding comparative analysis results.

[0113] Furthermore, the step S22 specifically includes the following steps:

[0114] When the current connection state is that both the terminal and the cloud are online, comparing the local online data version number of the local log file in the local data with the cloud online data version number of the cloud log file of the cloud data to obtain an online data version number analysis result;

[0115] When the current connection state is that the terminal and / or the cloud is in an offline state, the local offline data version number of the local log file is compared with the cloud offline data version number of the cloud log file to obtain an offline data version number analysis result.

[0116] It should be noted that when the terminal and the cloud are both online, the local data version number can be compared with the cloud data version number to obtain the online data version number analysis result; the local offline data version number can be compared with the cloud offline data version number to obtain the offline data version number analysis result.

[0117] Through the above scheme, this embodiment obtains the current connection status between the terminal and the cloud; compares and analyzes the local data and the cloud data according to the current connection status to obtain the comparison and analysis results, thereby ensuring the availability of the retail terminal and improving the data consistency and overall stability of the retail system in different network environments.

[0118] Further, Figure 5 FIG. 4 is a flow chart of a fourth embodiment of a method for synchronizing data between a retail terminal and a cloud in accordance with the present invention. Figure 5 As shown, a fourth embodiment of the data synchronization method between a retail terminal and a cloud of the present invention is proposed based on the first embodiment. In this embodiment, the step S30 specifically includes the following steps:

[0119] Step S31: When the comparison and analysis result shows that there is difference data, the data with the latest version number is selected according to the data synchronization component and the difference data to synchronize the data between the terminal and the cloud.

[0120] It should be noted that when the comparison and analysis result shows that there is difference data, the data with the latest version number can be selected according to the data synchronization component and the difference data to synchronize the data between the terminal and the cloud.

[0121] Step S32: After the data synchronization is completed, the offline state of the terminal or the cloud is switched to the online state according to the state switching component.

[0122] It is understandable that after the data synchronization is completed, the offline state of the terminal or the cloud can be switched to the online state according to the state switching component.

[0123] In the specific implementation, see Figure 6 , Figure 6 Schematic diagram of a retail system in the data synchronization method between a retail terminal and a cloud in the present invention, Figure 6 As shown, the mode switching component is responsible for intelligently switching the system's online and offline modes to ensure the continuity and flexibility of operation;

[0124] Online mode: All data changes will be synchronized to the cloud database and local database in real time to ensure the real-time and accuracy of the data.

[0125] Offline mode: When the connection with the cloud is disconnected, it will automatically switch to this mode, and all data changes will be recorded only in the local database; once the cloud connection is restored, the system will automatically return to online mode after data synchronization is completed; the cloud connection status is determined by a heartbeat detection mechanism, and it will be considered disconnected if the preset timeout number is exceeded.

[0126] The data synchronization component focuses on maintaining the consistency of data between the cloud and the terminal, and tracks data changes by recording data log files.

[0127] See also Figure 7 , Figure 7 Schematic diagram of log difference analysis in the data synchronization method between the retail terminal and the cloud of the present invention. Figure 7 As shown, log comparison and difference analysis: after the connection is restored in the cloud, first compare the data version numbers in the cloud and local log files; if the version numbers are the same, no synchronization is required; if they are different, further analyze the data differences.

[0128] The difference data processing process is:

[0129] If the local version number is newer, the local modification record will be uploaded to the cloud, and the cloud will synchronize the data; if the cloud version number is newer, the updated data will be pulled from the cloud and applied to the local database.

[0130] The synchronization completion notification process is as follows: after the data synchronization operation is completed, the status switching component is notified to proceed to the next step.

[0131] The online mode recovery process is as follows: after the state switching component confirms that the cloud connection is stable, it completes the switch of the system to online mode, ensuring that the system fully resumes normal operation, effectively improving the data consistency and overall stability of the system under different network environments.

[0132] Through the above scheme, this embodiment obtains the local data of the retail transaction to be synchronized in the terminal and the cloud data in the cloud; compares and analyzes the local data and the cloud data to obtain a comparison analysis result; when the comparison analysis result shows that there is difference data, synchronizes the data according to the difference data, thereby ensuring the availability of the retail terminal and improving the data consistency and overall stability of the retail system in different network environments.

[0133] Accordingly, the present invention further provides a data synchronization device between a retail terminal and a cloud.

[0134] Reference Figure 8 , Figure 8 It is a functional module diagram of a first embodiment of a data synchronization device between a retail terminal and a cloud according to the present invention.

[0135] In a first embodiment of the data synchronization device between a retail terminal and a cloud of the present invention, the data synchronization device between the retail terminal and the cloud comprises:

[0136] The data acquisition module 10 is used to acquire the local data of the retail transaction to be synchronized in the terminal and the cloud data in the cloud.

[0143] The comparison and analysis module 20 is further used to compare the local online data version number of the local log file in the local data with the cloud online data version number of the cloud log file of the cloud data to obtain an online data version number analysis result when the current connection state is that both the terminal and the cloud are online, and to compare the local offline data version number of the local log file with the cloud offline data version number of the cloud log file to obtain an offline data version number analysis result when the current connection state is that the terminal and / or the cloud are offline.

[0144] The data synchronization module 30 is also used to select the data with the latest version number to synchronize the data between the terminal and the cloud according to the data synchronization component and the difference data when the comparison and analysis result shows that there is difference data; after the data synchronization is completed, switch the offline state of the terminal or the cloud to the online state according to the state switching component.

[0145] The steps implemented by each functional module of the data synchronization device between the retail terminal and the cloud can refer to the various embodiments of the data synchronization method between the retail terminal and the cloud of the present invention, and will not be repeated here.
