Fig. 4 is a flowchart of a data management method according to an embodiment of the present invention. Referring to fig. 4, the method includes:

401. the server obtains a time zone policy of the server and a time zone policy of the front-end device.

In the embodiment of the present invention, the server may be configured with a plurality of time zone policies, and the time zone policies may be divided into two types, one type is a time zone policy of the server, and the other type is a time zone policy of the front-end device. The time zone strategy comprises a strategy type, a time zone, time entering summer time, time exiting summer time and time difference between summer time and winter time, wherein the strategy type is used for distinguishing the time zone strategy of the front-end equipment and the server. For example, the time zone may be the east two zone, the east eight zone, etc., and if the time zone in which the device is located is daylight savings time from 13:00 on 1/3/10 to 1/10/15: 00 on 1/3/year, the time to enter daylight savings time is 13:00 on 1/3/day, and the time to exit daylight savings time is 15:00 on 1/10/day.

In one possible implementation, the configuration of the time zone policy may be configured through a WEB page (WEB page) or an SDK (Software Development Kit) interface. In one possible implementation manner, the specific implementation flow for configuring the time zone policy may include the following three steps a to c:

step a, configuring a time zone strategy of a server through a webpage.

For example, a user may log in a configuration WEB page of a time zone policy on a terminal, the user may input and submit the time zone policy of the server on the WEB page, trigger the terminal to send the time zone policy of the server to the server, and the server stores the time zone policy, thereby completing configuration of the time zone policy of the server. The time zone policy of the server is a default time zone policy, and if the front-end device does not specify the time zone policy used by the front-end device, the server can default the time zone policy of the server adopted by the front-end device.

And step b, configuring the time zone strategy of the front-end equipment through the SDK interface.

The terminal can call a server SDK interface (cloud storage SDK interface) to connect with the server, add a time zone policy of the front-end device, and after the operation is successful, the SDK interface can return a unique policy ID (Identification) to the terminal, wherein the policy ID refers to the Identification of the time zone policy.

It should be noted that the server may access one or more front-end devices, and accordingly, in this step b, the time zone policy of at least one front-end device may be configured through the SDK interface.

And step c, the server acquires and stores the time zone policy table.

The time zone policy table includes time zone policies of the server and the front-end device and corresponding policy identifiers. Each time zone strategy comprises a strategy ID, a strategy type, a time zone, time entering summer time, time exiting summer time and time difference between summer time and winter time, wherein the strategy ID is used for distinguishing different time zone strategies, and the strategy type comprises a time zone strategy of a server and a time zone strategy of front-end equipment.

After the server obtains the time zone policies of the server and each front-end device through the steps a and b, an identifier of each time zone policy can be generated; and generating the time zone policy table according to the identifier of each time zone policy, the time zone policies of the server and the front-end equipment.

The server is configured with the time zone strategy of the server and the time zone strategies of the front-end devices, so that the server can store the acquired data according to the time zone strategies of the front-end devices and provide the data to the terminal for data query.

It should be noted that, the above manner is only described by taking the example of configuring the time zone policy of the server through the web page and configuring the time zone policy of the front-end device through the SDK interface, and it can be understood that the time zone policy of the server may also be configured through the SDK interface and the time zone policy of the front-end device may also be configured through the web page, which is not limited in the embodiment of the present invention.

Referring to fig. 5, fig. 5 is a flowchart of configuring a time zone policy according to an embodiment of the present invention, and as shown in fig. 5, taking data as video data as an example, a server may include a video management service module, a data collection plan management service module, a video access service module, and a video storage service module. The video management service module is used for managing the configuration of time zone policies and the storage of video data; the data acquisition plan management service module is used for configuring a data acquisition plan (video recording plan); the video access service module is used for receiving video data sent by the front-end equipment; the video storage service module is used for storing video data.

The data collection plan management service module can synchronize a time zone policy table including a time zone policy of the server and a time zone policy of the front-end device from the video management service module in time. For example, the video management service module may send the time zone policy table to the data collection plan management service module at regular time or in real time. In addition, the data collection plan management service module may synchronize the time zone policy table to the video access service module in time, for example, the data collection plan management service module may send the time zone policy table to the video access service module at regular time or in real time.

It should be noted that fig. 5 illustrates an example in which functions of four modules, namely a video management service module, a data collection plan management service module, a video access service module, and a video storage service module, are integrated on one server, and an interaction process of the four modules is an interaction process between modules in the same server. It should be understood that the functions of each of the modules may also be provided by one server, that is, the interaction process of the four modules is actually an interaction process between four servers, which is not limited in the embodiment of the present invention.

In the embodiment of the invention, the server can acquire and store the data acquired by the front-end equipment according to the data acquisition plan. The data acquisition plan comprises an identifier of the front-end equipment, a data acquisition time template and an identifier of a time zone strategy, wherein the data acquisition time template is used for indicating a time period for the front-end equipment to acquire data, and the time zone strategy comprises time zone information of the front-end equipment. The configuration process of the data acquisition plan is the same as the configuration process of the time zone policy, and the terminal may configure the data acquisition plan to the server through the SDK interface, and certainly, the data acquisition plan may also be configured through a WEB page, which is not limited in the embodiment of the present invention.

In one possible implementation manner, the way in which the server stores the data of any front-end device may be: acquiring the time zone strategy of the front-end equipment according to the identifier of the time zone strategy of the front-end equipment in the data acquisition plan; and according to the time zone strategy of the front-end equipment, storing the data acquired by the front-end equipment in a segmented manner to obtain a plurality of pieces of data, wherein the plurality of pieces of data are acquired by the front-end equipment in a plurality of time zones, the plurality of pieces of data correspond to a plurality of time difference information, and the time difference information corresponding to each piece of data is used for indicating the time difference between the time zone time for acquiring each piece of data by the front-end equipment and the standard time.

When receiving data collected by any front-end equipment, the server can query a time zone policy table according to the time zone policy identifier of the front-end equipment, and determine the time zone policy of the front-end equipment, so that the time difference information of the front-end equipment in each time period can be obtained.

By storing the data acquired by the front-end equipment in a segmented manner, the data acquired by the front-end equipment in each time zone in each time period can be better distinguished, and a user can conveniently perform query operation.

Referring to fig. 6, fig. 6 is a flowchart for acquiring data according to an embodiment of the present invention. As shown in fig. 6, the terminal may configure a data acquisition plan to a data acquisition plan management service module through the SDK interface, where the data acquisition plan management service module is configured to send the data acquisition plan to the video access service module, and the video access service module executes a task of acquiring a real-time data stream from the front-end device according to information in the data acquisition plan.

After the video access service module obtains the data, the video access service module may write the data into the video storage service module, and the video access service module needs to communicate with the video management service module first to apply for the storage resource, for example, the video access service module may send an application resource protocol to the video management service module, where the application resource protocol includes an encoder ID of the front-end device, start time of the video data, and time difference information of the front-end device (a time difference between time zone time of the front-end device and standard time). After receiving the resource application protocol, the video management service module can return the applied storage resource to the video access service module according to a resource allocation policy (load balancing policy), and meanwhile, the video management service module can record time zone information of the front-end device. For example, the video management service module may record the time zone information of the front-end device in a time zone information table. Referring to table 1, a time zone information table is provided, in which an encoder ID of a front end device and time difference information of the front end device for at least one period of time may be recorded as shown in table 1.

TABLE 1

If the time zone policy of the front-end device is changed, which causes the time difference between the time zone time of the front-end device and the standard time to be changed, the video management service module may add a record in the time zone information table every time the time difference is changed. As shown in table 1, the time zone of the front-end device with the encoder ID Test1 in the time period from 23:00 at 12/23/12/01/2018/04/2018/12/23: 00 is the east 3 zone, the time difference is 3 hours (hour), the front-end device changes the time zone from 23:00 at 12/23/2018/4/12/east 3 zone to east two zone, and the time difference is 2 hours, and then the server may add a new record in the video management service module. Since the time difference is changed from 3 hours to 2 hours, 12 days 04-2018 at 23:00 is changed to 12 days 04-2018 at 22:00, and if the time zone policy of the front-end equipment is changed from the change to the current time, the start time of the newly added record is 22:00 days 04-12-2018 at 12, and the end time is the current time.

Of course, in addition to the time zone policy of the front-end device being changed, which may result in the time difference information of the front-end device being changed, the reason for the time difference change may also be the change between daylight saving time and winter time, such as when the front-end device enters east time from daylight saving time, or when the front-end device enters daylight saving time from east time.

When the video access service module writes the video data into the video storage service module, the video access service module may provide the time difference information of the video data (the time difference information of the front-end device that sends the video data) to the video storage service module, and the video storage service module may store the information in the storage block device for backup.

And writing the video data into the block device of the bottom layer by the video storage service module for storage. Referring to fig. 7, fig. 7 is a structural diagram of a data storage according to an embodiment of the present invention, and as shown in fig. 7, when storing video data, a video storage service module may divide the video data into a plurality of video segments, such as video segment 1 and video segment 2. The segment information corresponding to each video segment includes the start time, the end time, and the time difference from the UTC time, and the video management service module may store data using standard time.

403. The terminal sends a data query request to the server, wherein the data query request carries an identifier of front-end equipment, a first starting time and a first ending time, the time types of the first starting time and the first ending time are standard time, and the standard time is the time types of the starting time and the ending time of data stored by the server.

In the embodiment of the present invention, after the server obtains the data from the front-end device and stores the data, the user may perform operations such as query, download or playback on the data collected by a certain front-end device, where query operations are required before download and playback, that is, the data collected by the front-end device needs to be queried first. Specifically, the user may input an identification of the front-end device to be queried and a query time period, including a start time and an end time, on the terminal. Since the time saved by the server bottom data is the standard time, in a possible implementation manner, when the terminal acquires the identifier, the start time, and the end time of the front-end device input by the user and the time type of the input start time and end time is the standard time, the terminal may send the data query request to the server by using the input start time and end time as the first start time and the first end time.

It should be noted that there may be two metering modes for the standard time, one is UTC time, one is UNIX timestamp, and the time used by the terminal is X years, X months, X days, X minutes and X seconds. If the time type of the start time and the end time of the server storage data is the UTC time and the time type of the start time and the end time input by the user on the terminal is also the UTC time, the terminal may directly take the start time and the end time input by the user as the first start time and the first end time, such that the time type of the first start time and the first end time is the UTC time.

If the time type of the start time and the end time of the server storage data is UNIX timestamp, and the time type of the start time and the end time input by the user on the terminal is UTC time, the terminal needs to convert the start time and the end time input by the user into UNIX timestamp first, for example, the terminal may convert the UTC time into UNIX timestamp through the SDK interface, and use the converted start time and end time as a first start time and a first end time, so that the time type of the first start time and the first end time is UNIX timestamp.

Compared with the prior art that data query is carried out only by supporting the time zone time of the front-end equipment input by the user, the data query method has the advantage that the flexibility of the data query is improved by providing the mode of carrying out the data query by inputting the standard time by the user.

404. When a data query request of a terminal is received, a server acquires target data, first time difference information, and start time and end time of the target data, which are acquired by front-end equipment, according to the identifier of the front-end equipment, the first start time and the first end time.

The time period between the start time and the end time of the target data is a first time period, the first time period is included in the time period between the first start time and the first end time, and the first time difference information is used for indicating the time difference between the time zone time of the front-end device in the first time period and the standard time.

In the embodiment of the invention, when the server receives the data query request of the terminal, the stored data can be queried according to the first starting time and the first ending time carried in the data query request. Since the time type of the start time and the end time of the server stored data is the standard time, and the time type of the first start time and the first end time is also the standard time, in a possible implementation manner, the process of the server obtaining the target data, the first time difference information, and the start time and the end time of the target data includes:

and when the time period between the start time and the end time of any inquired data segment is included in the time period between the first start time and the first end time, the inquired data segment is used as the target data, the time difference information corresponding to the inquired data segment is used as the first time difference information, and the start time and the end time of the inquired data segment are used as the start time and the end time of the target data.

The server stores the data collected by the front-end device in a segmented manner in step 402, and when the target data is queried and the time period between the start time and the end time of any data segment is included in the time period between the first start time and the first end time, the server may return the data to the terminal as a query result. In addition, when the server inquires the target data, the server can simultaneously inquire the start time, the end time and the first time difference information recorded in the information of the target data.

405. The server transmits the target data, the first time difference information, and the start time and the end time of the target data to the terminal.

In the embodiment of the invention, when the server returns the target data to the terminal as the query result, the server can also return the start time and the end time of the target data and the corresponding first time difference information to the terminal.

406. When receiving the target data, the first time difference information and the start time and the end time of the target data, the terminal converts the start time and the end time of the target data into a second start time and a second end time according to the first time difference information, wherein the time types of the second start time and the second end time are the time zone time of the front-end equipment.

The second start time is the time when the front-end device starts to collect the target data, and the second end time is the time when the front-end device finishes collecting the target data.

In the embodiment of the invention, when the user inquires data, the user usually wants to see the data collected by the front-end equipment in the local time zone time so as to know the events occurring in different time zones in a certain time period. Since the time types of the starting time and the ending time of the target data returned by the server are standard time, in order to inform the local time zone time when the front-end equipment collects the target data to the user, after receiving the target data returned by the server, the terminal can also determine the local time zone time when the front-end equipment collects the target data. And the first time difference information indicates the time difference between the time zone time and the standard time when the front-end equipment collects the target data. Therefore, the terminal can convert the start time and the end time of the target data into the local time zone time of the front-end equipment according to the first time difference information corresponding to the target data.

If the start time and the end time of the data stored in the server are the UTC time, that is, the start time and the end time of the target data are the UTC time, the terminal needs to convert the UTC time into a time zone time of the front-end device.

If the start time and the end time of the server storage data are UNIX timestamps, that is, the start time and the end time of the target data are UNIX timestamps, the terminal needs to convert the UNIX timestamps to the time zone time of the front-end device, for example, the terminal may convert the UNIX timestamps to the time zone time of the front-end device through the SDK interface, so as to obtain a second start time and a second end time.

407. The terminal displays the target data and the second start time and the second end time.

In the embodiment of the invention, the terminal can display the target data after receiving the target data sent by the server. In addition, the terminal can also display the local time zone time when the front-end device collects the target data, namely the second start time and the second end time, so that the user can know the start time and the end time when the front-end device collects the data, and further know the events occurring in the collection range of the front-end device in the time period.

Optionally, when the terminal displays the target data, the second start time and the second end time, the terminal may also display first time difference information corresponding to the target data, so that a user may know a time difference between a time zone time when the front-end device collects the target data and a standard time.

The technical scheme provided by the embodiment of the invention simultaneously supports data management of the terminal, the server and the front-end equipment under different time zone strategies. In particular, the front-end equipment access supporting multiple time zones is realized, for example, the encoder 1 of the front-end equipment 1 is in the east two zone, and the encoder 2 of the front-end equipment 2 is in the east eight zone. When data control operation is carried out, the system automatically identifies local time of the Dongbei area adopted by the front-end equipment 1 to carry out query, playback and download operation, and automatically identifies local time of the Dongbei area adopted by the front-end equipment 2 to carry out query, playback and download operation.

In addition, the technical scheme also supports a data management method of multiple time zone strategies of the same front-end equipment. For example, the time zone of the encoder 1 of the front-end device 1 in month 1 is the east two zone, and in month 2, the time zone is changed into the east three zone due to human factors, so that when data control operation is performed, the time zone difference of different time periods is automatically identified in the system, and corresponding query, playback and download results are returned.

The technical scheme supports a mode of inquiring data according to standard time, and the server returns time zone information corresponding to the data besides the data.

The embodiment corresponding to fig. 4 is a data query process for the case that the input query time is standard time (UTC time), and the query time input by the user on the terminal may also be time zone time of the front-end device, in which case the data query process will be explained in the embodiment corresponding to fig. 8.

Fig. 8 is a flowchart of a data management method according to an embodiment of the present invention. Referring to fig. 8, the method includes:

801. the server obtains a time zone policy of the server and a time zone policy of the front-end device.

802. And the server acquires data from the front-end equipment for storage.

The above steps 801 to 802 are similar to the steps 401 to 402, and are not described herein again.

803. When the input identifier of the front-end device, the third starting time and the third ending time are obtained, the terminal sends a time difference query request to the server, and the time types of the third starting time and the third ending time are the time zone time of the front-end device.

The time difference query request carries the identifier of the front-end device, the third start time and the third end time, the time difference query request is used for acquiring time difference information of the front-end device in a time period corresponding to the third start time and the third end time, and the time difference information is used for indicating the time difference between the time zone time of the front-end device in the time period and the standard time.

In the embodiment of the present invention, a user may input an identifier of a front-end device to be queried and a query time period on a terminal, where a start time and an end time of the query time period adopt a local time zone time of the front-end device, that is, a third start time and a third end time. Because the time saved by the server bottom data is standard time, the terminal needs to perform time conversion according to the time difference between the time zone time of the front-end device and the standard time, and perform data query operation after converting the start time and the end time of the query time period into the standard time. For this reason, the terminal may carry the identifier of the front-end device, the third start time, and the third end time in the time difference query request and send the time difference query request to the server, so that the server may return the time difference information of the front-end device to be queried in the query time period. For example, the terminal may call the SDK interface to communicate with the server, and send the time difference query request to the server.

804. When receiving a time difference query request of the terminal, the server obtains second time difference information of the front-end device in a second time period, and sends the second time difference information to the terminal, wherein the second time period is a time period between the third starting time and the third ending time, and the second time difference information is used for indicating the time difference between the time zone time of the front-end device in the second time period and the standard time.

In one possible implementation, the process of the server obtaining the second time difference information may include: and inquiring a time zone information table according to the third starting time and the third ending time to obtain the time difference information, wherein the time zone information table is used for recording the time difference information of the front-end equipment in at least one time period.

The time zone information table refers to table 1 in step 402, and the server may return the acquired time difference information to the terminal after acquiring the time difference information in the second time period by querying the time zone information table.

805. And when receiving the second time difference information sent by the server, the terminal converts the third starting time and the third ending time into the first starting time and the first ending time according to the time difference information and then sends a data query request to the server.

The data query request carries an identifier of a front-end device, a first start time and a first end time, the time types of the first start time and the first end time are standard times, and the standard times are the time types of the start time and the end time of the data stored by the server.

In a possible implementation manner, after the terminal receives the time difference information returned by the server, the third start time and the third end time may be converted into standard times, that is, the first start time and the first end time, according to the time difference information.

If the time type of the start time and the end time of the server-stored data is the UTC time, since the time type of the third start time and the third end time is the time zone time of the front-end device, the terminal needs to convert the start time and the end time input by the user into the UTC time.

If the time type of the start time and the end time of the server storage data is UNIX timestamp, since the time type of the third start time and the third end time is time zone time of the front-end device, the terminal needs to convert the start time and the end time input by the user into UNIX timestamp, for example, the terminal may convert the time zone time of the front-end device into UNIX timestamp through the SDK interface, and use the converted time as the first start time and the first end time.

Further, as the same as step 403, since the first start time and the first end time are standard times and are the same as the time types of data stored by the server, the terminal may carry the identifier of the front-end device, the first start time and the first end time in the data query request and send the data query request to the server for data query.

806. When a data query request of a terminal is received, a server acquires target data, first time difference information, and start time and end time of the target data, which are acquired by front-end equipment, according to the identifier of the front-end equipment, the first start time and the first end time.

807. The server transmits the target data, the first time difference information, and the start time and the end time of the target data to the terminal.

808. When receiving the target data, the first time difference information and the start time and the end time of the target data, the terminal converts the start time and the end time of the target data into a second start time and a second end time according to the first time difference information, wherein the time types of the second start time and the second end time are the time zone time of the front-end equipment.

809. The terminal displays the target data and the second start time and the second end time.

The above steps 806 to 809 are similar to the steps 404 to 407, and are not described herein.

It should be noted that, the above steps 803 to 809 are data query processes in the case that the input query time is the time zone time of the front-end device. Referring to fig. 9, fig. 9 is a flowchart of data query according to an embodiment of the present invention, as shown in fig. 9, a terminal first obtains time difference information of a front-end device in a query time period from a server, and after the server returns the time difference information to the terminal, the terminal performs a data query operation, and the server returns a data query result to the terminal.

In the technical solution provided in the embodiment of the present invention, the server may support access of a plurality of front-end devices, and the plurality of front-end devices may be in different time zones, and the time zones of the same front-end device in different time periods may also be different. The time difference information of each front-end device in each time period is pre-stored in the server, so that when the terminal needs to inquire the data of any front-end device, the time difference information of the front-end device in the time period input by the user can be acquired from the server, and then the time zone time of the front-end device is converted into the standard time according to the time difference information returned by the server, and then the inquiry operation of the data is carried out.

The technical scheme simultaneously supports data management of the terminal, the server and the front-end equipment under different time zone strategies. In particular, the front-end equipment access supporting multiple time zones is realized, for example, the encoder 1 of the front-end equipment 1 is in the east two zone, and the encoder 2 of the front-end equipment 2 is in the east eight zone. When data control operation is carried out, the system automatically identifies local time of the Dongbei area adopted by the front-end equipment 1 to carry out query, playback and download operation, and automatically identifies local time of the Dongbei area adopted by the front-end equipment 2 to carry out query, playback and download operation.

It can be seen that the server can support two data query modes, one is that the user inputs standard time (UTC time) on the terminal, and the time of the data returned by the query result is the time zone time of the front-end device, and the specific process is shown in the embodiment corresponding to fig. 4. The other is that the user inputs the time zone time of the front-end device on the terminal, and the time of the data returned by the query result is the time zone time of the front-end device, and the specific process is as shown in the embodiment corresponding to fig. 8.
