[0039] <System Embodiment>

[0040] Figure 1 FIG. 1 is a schematic diagram of the composition structure of a data storage system to which a data storage method according to an embodiment can be applied. Figure 1 As shown, the system may include a data storage device, a first device and a second device. The system may be applied to public transportation scenarios, such as trains, subways or passenger buses, etc., which are not limited here. The system is specifically, for example, an automatic fare collection (AFC) system.

[0041] The first device is, for example, a computer or a server, etc., which is not limited here. The first device can be used to obtain operation information of one station or multiple stations, which is not limited here.

[0042] The second device is, for example, a computer, a mobile phone, or a tablet, and can receive a data modification instruction, which can be sent to the second device after a human confirms that the station operation situation has changed, or can be sent to the second device after other devices detect that the station operation situation has changed, which is not limited here. The second device can generate and send corresponding modification data according to the received data modification instruction.

[0043] The data storage device is, for example, a computer or a server, etc., which is not limited here. The data storage device can be connected to the first device and the second device for communication, and the data storage device can receive the operation information sent by the first device, and can also receive the modification data output by the second device.

[0044] As used in the embodiments of the present disclosure, the memory of the data storage device 100 is used to store a computer program, and the computer program is used to control the processor of the data storage device 100 to operate according to the data storage method of any embodiment. A technician can design a computer program according to the scheme of the embodiments of the present disclosure. How the computer program controls the processor to operate is well known in the art, so it will not be described in detail here.

[0045] <Method Example>

[0046] Figure 2 is a flow chart of a data storage method according to an embodiment. Figure 1 The data storage device 100 is shown in FIG.

[0047] like Figure 2 As shown, the material strip unloading control method of this embodiment may include the following steps S210 to S230:

[0048] Step S210, in response to the user's data retrieval request, determining the data retrieval time and the data type to be retrieved.

[0049] In this embodiment, the user can send a data retrieval request to the data storage device through his terminal device.

[0050] In this embodiment, the data retrieval request may be to retrieve data of a specified period of time, to retrieve data of a specified data type, or to retrieve data of a specified period of time and a specified data type, which is not limited here.

[0051] In some examples, the retrieved data type may be one or more specified data types, such as transaction data, business data, log data, ticket checking data, status data, parameter data, and report data.

[0052] The above transaction data can be generated by the terminal device according to the requirements of the clearing center system, and records the transaction results of the user's terminal device paying for the ticket. The transaction data includes, for example, one-card transaction data, one-ticket transaction data, internal transaction data, etc., which are not limited here.

[0053] The above business data may be generated when a user or a terminal device of a station completes a specific business, and the business data may record the process and results of the business execution. For example, the business data may include feedback from a terminal device of station R1 that a train of train A01 has completed its departure in a certain time period.

[0054] The above log data may be generated when a user's terminal device or a station device completes a specific task, and the log data may record the device that performs the task and each time node of the task. For example, the log data may include feedback from the terminal device of station R2 that the train of A03 arrives at the station at 10 o'clock.

[0055] The above-mentioned ticket checking data may be generated when the user's terminal device or the station's equipment obtains the user's completion of the ticket checking action. For example, the ticket checking data may include feedback from the terminal device of station R3 that 200 people entered the station between 10 and 11 o'clock.

[0056] The above status data may be generated when the status of the user's terminal device or the station's equipment changes. For example, the status data may include the feedback from the terminal device of station R4 that the ticket gate at station R4 is in the damaged state T1 at 14:00.

[0057] The above parameter data may be prefabricated data for controlling the implementation of a specified business to meet operational needs and business change requirements. For example, the parameter data may include ensuring that the driving voltage for opening and closing the map entry and exit gate of station R5 is within a normal range.

[0058] The above-mentioned report data may be the statistical result of transaction data within a certain time period. For example, the report data may include that the total revenue of station R6 from 2023 to 2024 is four hundred thousand.

[0059] In some examples, the retrieved data type may be one or more of the above data types, which are not limited here.

[0060] Step S220, selecting a matching database from a set database according to the data retrieval time and the data retrieval type; wherein the database includes a matching database, and the first data stored in the matching database conforms to the data retrieval time and the data retrieval type.

[0061] In some examples, the database may be pre-set to be multiple, for example, the database may include a real-time database and a historical database, the real-time database may store the data of the day, and the data type of the data of the day may include transaction data, business data, log data, ticket checking data, status data, parameter data, and report data. The historical database may store the data before the day, and the data type of the data before the day may include transaction data, business data, ticket checking data, status data, and report data. When the data retrieval time is the day and the retrieval data type is transaction data, the matching database is the real-time database, and the first data corresponds to the transaction data in the real-time database.

[0062] For another example, a database may include a real-time database and a historical database. The real-time database may store data for the current day, and the data types of the data for the current day may include transaction data, business data, log data, ticket checking data, status data, and parameter data. The historical database may store data for the current day whose data type is report data, and store data before the current day, and the data types of the data before the current day may include transaction data, business data, ticket checking data, status data, and report data. When the data retrieval time is yesterday and the retrieval data type is transaction data, the matching database is the historical database, and the first data corresponds to the transaction data in the historical database.

[0063] In some embodiments, different databases correspond to different database types; data stored in a first database of a first database type is within a first set time period, and data stored in a second database of a second data type is within a second set time period; wherein the database includes a first database and a second database, the database types include a first database type and a second database type, and the first set time period is the first part of the second set time period.

[0064] In some examples, the first set time period can be the current day, and the second set time period can be the current day and the six months before the current day, or the current day and the year before the current day, etc., without limitation here. For example, the data stored in the real-time database is the data of the current day and the data types are transaction data, business data, log data, ticket checking data, status data and parameter data, and the data stored in the historical database includes the data of the current day and the data type is report data, as well as the data within the year before the current day and the data type is transaction data, business data, ticket checking data, status data and report data. In other words, splitting the database into the first database and the second database according to time can enable the real-time database to retain the data of the current day, so that the real-time database can be in the optimal state.

[0065] In some embodiments, the first partial time period is after the second partial time period; wherein the second partial time period is the remaining time period of the second set time period except the first set time period.

[0066] In some examples, the first set time period can be the current day, and the second set time period can be the six months before the current day, or the year before the current day, etc., which are not limited here. For example, the data stored in the real-time database is for the current day and the data types are transaction data, business data, log data, ticket checking data, status data, parameter data, and report data, and the data stored in the historical database is for the year before the current day and the data types are transaction data, business data, ticket checking data, status data, and report data. In other words, if the user frequently retrieves the report data for the current day, the report data for the current day can be stored in the real-time database to improve the data retrieval efficiency.

[0067] In some embodiments, the data stored in the first database corresponds to the first data type or the second data type respectively, and the data stored in the second database corresponds to the first data type.

[0068] In some examples, the first data type may be one or more of transaction data, business data, ticket checking data, status data, parameter data, and report data, and the second data type may be one or two of log data and parameter data. In other words, since parameter data and log data only reflect the operation of terminal devices of users or stations, etc., only storing parameter data and log data in the real-time library can effectively improve the utilization efficiency of the storage space of the historical library.

[0069] Step S230: sending first data to the user.

[0070] In other words, public transportation data can be split and stored in different databases according to time and type. This allows the user to select a matching database based on the retrieval time and retrieval data type when the user issues a data retrieval request, and send the corresponding first data to the user. This improves data retrieval efficiency while making reasonable use of the storage space of each database.

[0071] In some embodiments, the data stored in the first database corresponds to different change conditions, the first part of the data in the first database corresponds to the first change condition, the second part of the data in the first database corresponds to the second change condition, the first part of the data and the second part of the data correspond to the second data type, the first change condition is that the first device sends the reported data regularly, and the second change condition is that after the second device receives the data modification instruction, the second device sends the modified data; wherein the change condition includes the first change condition and the second change condition;

[0072] The method further includes the following steps S310 and S320:

[0073] Step S310: When a first change event is triggered, a first portion of data in a first database is updated according to reported data sent by a first device.

[0074] In some examples, the data type of the first part of data may be log data or status data, and the period may be one hour, half a day, or one day, etc., which are not limited here. For example, the reported data is that the ticket gate of station R6 is damaged, and [R6, T0] in the first part of data in the second database is updated to [R6, T1].

[0075] Step S320: When a second change event is triggered, the second part of data in the second database is updated according to the modification data sent by the second device.

[0076] In some examples, the second data type also includes configuration data and user information data. The data type of the second part of the data is configuration data. The second part of the data may include line information of public transportation, such as station information, the address of the terminal device at the station, or the coordinates of the station, etc., which are not limited here. The data type of the second part of the data is user information data. The second part of the data may include user registration information and user payment information, etc., which are not limited here. For example, the modified data is that the coordinates of station R6 are changed from AD01 to AD03, and [R6, AD01] in the second part of the data in the second database is updated to [R6, AD03].

[0077] In other words, by setting different change events, the data in the first database is updated, thereby effectively improving the accuracy of the data in the first database.

[0078] In some embodiments, the method further includes the following steps S410 and S420:

[0079] Step S410: When the set first update condition is triggered, the second database is updated according to the data stored in the first database.

[0080] In some examples, the first update condition is, for example, that data of a certain data type in the first database exceeds the corresponding storage period. The storage periods of data of different data types in the first database are specifically as shown in Table 1 below:

[0081] Table 1:

[0082]

[0083] In Table 1, the storage period of transaction data, business data, status data and parameter data is 365 days, the storage period of ticket checking data is 7 days, and the storage period of report data is 365×3 days. In addition, transaction data, business data, ticket checking data, status data and report data will be stored in the history library after the corresponding storage period ends. The storage period of transaction data, business data, ticket checking data, status data and report data in the history library is 365×3 days.

[0084] Step S420: when the update of the second database is completed, the data stored in the first database is deleted.

[0085] In some examples, the transaction data of the first year stored in the first database may be stored in the second database after the end of the first year, and if the storage in the second database is successful, the transaction data of the first year may be deleted from the first database.

[0086] In other words, by first updating the data stored in the first database to the second database and then deleting the data stored in the first database, the occurrence of deviations in the data stored in the first database during transmission can be effectively reduced, thereby improving the accuracy of the data stored in the second database.

[0087] In some embodiments, step S410 may include the following steps S4101 and S4102:

[0088] Step S4101: Generate data to be stored according to the third part of data stored in the first database.

[0089] In some examples, the data type corresponding to the third part of data may be transaction data or ticket checking data, and the data storage device may generate data to be stored whose data type is report data based on the transaction data or ticket checking data.

[0090] Step S4102: Update the fourth part of data and the data to be stored stored in the first database into the second database.

[0091] In some examples, the data to be stored whose data type is report data and the fourth part of data whose data types are transaction data, business data, ticket checking data and status data are updated in the second database.

[0092] In other words, the third part of data is generated as band storage data to be stored in the second database to adapt to different public transportation systems.

[0093] In some embodiments, the method further includes the following steps S510 and S520:

[0094] Step S510: When the set second update condition is triggered, the set tape library is updated according to the data stored in the second database.

[0095] In some examples, as shown in Table 1, data of the data types transaction data, status data, and report data can be stored in a tape library after the historical library data retention period ends.

[0096] Step S520: when the tape library update is completed, the data stored in the second database is deleted.

[0097] In some examples, the transaction data of the third year stored in the second database may be stored in a tape library after the third year reaches three years, and if the storage in the tape library is successful, the transaction data of the third year is deleted from the second database.

[0098] In other words, by storing data whose data types are transaction data, status data or report data in a tape library, the security of the data in the data storage device can be improved.

[0101] The data storage device 300 also includes a trigger module, which is used to update the first part of the data in the first database according to the reported data sent by the first device when a first change event is triggered; and to update the second part of the data in the second database according to the modified data sent by the second device when a second change event is triggered.
