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

In the embodiment of the invention, a plurality of time zone policies can be configured in the server, and the time zone policies can be divided into two types, namely, the time zone policies of the server and the time zone policies of the front-end equipment. The time zone policy includes a policy type, a time zone, a time to enter daylight savings time, a time to exit daylight savings time, and a time difference between daylight savings time and winter time, the policy type being used to distinguish between the time zone policies of the head-end equipment and the server. For example, the time zone may be Dong's second zone, dong's eighth zone, etc., and if the time zone in which the device is located is daylight savings time at 3 months 1 day 13:00 to 10 months 1 day 15:00 each year, then the time to enter daylight savings time is 3 months 1 day 13:00 and the time to exit daylight savings time is 10 months 1 day 15:00.

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

And a time zone strategy of the server is configured through the webpage.

For example, a user may log in a configuration WEB page of a time zone policy on a terminal, and the user may input and submit the time zone policy of a 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 it uses, the server may default the front-end device to employ the server's time zone policy.

And b, configuring a 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 the time zone policy of the front-end equipment, 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, in this step b, the server may access one or more front-end devices, and accordingly, a time zone policy of at least one front-end device may be configured through the SDK interface.

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

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

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 identification of each time zone policy and the time zone policies of the server and the front-end equipment.

The time zone strategy of the server and the time zone strategy of each front-end device are configured in the server, so that the server can store collected data according to the time zone strategy of each front-end device and provide the collected data for the terminal to perform data query.

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

Referring to fig. 5, fig. 5 is a flowchart of a time zone policy configuration, where, as shown in fig. 5, taking data as video data as an example, a server may include a video management service module, a data acquisition 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 the time zone strategy 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 from the video management service module in time, including a time zone policy of the server and a time zone policy of the front-end device. For example, the video management service module may send the time zone policy table to the data collection plan management service module at regular or real-time. In addition, the data acquisition plan management service module may synchronize the time zone policy table to the video access service module in time, e.g., the data acquisition plan management service module may send the time zone policy table to the video access service module at regular or real-time.

It should be noted that, fig. 5 illustrates that functions of four modules, such as a video management service module, a data acquisition 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 each module in the same server. It will be appreciated that the functions of each module may be provided by one server, that is, the interaction between the four modules is actually an interaction between the four servers, which is not limited by the embodiment of the present invention.

402. The server acquires data from the front-end equipment and stores the data.

In the embodiment of the invention, the server can acquire the data acquired by the front-end equipment according to the data acquisition plan and store the data. 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 can configure the data acquisition plan to the server through the SDK interface, however, the data acquisition plan can also be configured through a WEB page, which is not limited in the embodiment of the present invention.

In one possible implementation, the manner in which the server stores the data of any front-end device may be: acquiring a time zone strategy of the front-end equipment according to the identification 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, the data acquired by the front-end equipment are stored in a segmented mode to obtain multiple pieces of data, the multiple pieces of data are acquired by the front-end equipment in multiple time zones, the multiple pieces of data correspond to multiple pieces 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 of the front-end equipment for acquiring each piece of data and the standard time.

When the server receives data collected by any front-end equipment, the time zone policy table can be queried according to the time zone policy identification of the front-end equipment, and the time zone policy of the front-end equipment is determined, so that the time difference information of the front-end equipment in each time period is known, the server can store the data in a segmented mode according to the time difference information of the front-end equipment in each time period, and the data collected in the same time zone is divided into one segment, so that one segment of data corresponds to one time difference information.

The data collected by the front-end equipment are stored in a segmented mode, so that the data collected by the front-end equipment in each time zone in each time period can be better distinguished, and a user can conveniently inquire.

Referring to fig. 6, fig. 6 is a flowchart of 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 an SDK interface, where the data acquisition plan management service module is configured to issue the data acquisition plan to a video access service module, and the video access service module performs a task of acquiring a real-time data stream from a front-end device according to information in the data acquisition plan.

After the video access service module obtains the data, the data can be written 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 storage resources, for example, the video access service module can 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, a start time of the video data, and time difference information (time difference between time zone time of the front end device and standard time) of the front end device. 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 the resource allocation strategy (load balancing strategy), and meanwhile, the video management service module can record the time zone information of the front-end equipment. For example, the video management service module may record time zone information of the head-end device in a time zone information table. Referring to table 1, there is provided a time zone information table in which encoder IDs of the head-end apparatuses, time difference information of the head-end apparatuses in at least one time period can be recorded as shown in table 1.

TABLE 1

If the time zone policy of the front-end equipment is changed, so that the time difference between the time zone time of the front-end equipment and the standard time is changed, the video management service module can add a record in the time zone information table every time the time difference is changed. As shown in table 1, the front-end device with the encoder ID Test1 has a time zone of 3 hours (hours) in the east 3 region in the period from 23:00 in 2018, 01, 12, and 23:00 in 2018, 04, 12, and a time difference of 3 hours (hours), the front-end device changes the time zone from 3 hours in the east to two hours in 2018, 12, 23:00, and the time difference changes to 2 hours, so that the server can add a record in the video management service module. Since the time difference changes from 3 hours to 2 hours, 23:00 in 12 months in 2018 04 month changes to 22:00 in 12 months in 2018 month, if the time zone policy of the front-end device changes from the change to the current time, the start time of the newly added record is 22:00 in 12 months in 2018 month, and the end time is current.

Of course, besides that the time zone policy of the front-end device is changed, the time difference information of the front-end device is changed, and the reason for the time difference change may be that the front-end device enters the daylight saving time from the daylight saving time or the front-end device enters the daylight saving time from the daylight saving time.

When the video access service module writes video data into the video storage service module, the video access service module can provide time difference information of the video data (time difference information of front-end equipment sending the video data) for the video storage service module, and the video storage service module can store the information into the storage block equipment for backup.

Video data is written into the underlying block device by the video storage service module for storage. Referring to fig. 7, fig. 7 is a block diagram of a data storage according to an embodiment of the present invention, and as shown in fig. 7, when video data is stored, 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 a start time, an end time, and a time difference from the UTC time, and the video management service module may use standard time to store data.

403. The terminal sends a data query request to a server, wherein the data query request carries an identifier of a front-end device, 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 type of the starting time and the ending time of the data stored by the server.

In the embodiment of the invention, after the server acquires the data from the front-end equipment and stores the data, a user can perform operations such as inquiring, downloading or playing back the data acquired by a certain front-end equipment, wherein the inquiring operation is required before downloading and playing back, that is, the data acquired by the front-end equipment is required to be inquired first. Specifically, the user may input, on the terminal, the identification of the front-end device to be queried and a query time period, including a start time and an end time. Because the time of the server underlying data storage is the standard time, in one possible implementation manner, when the terminal obtains the identifier, the start time and the end time of the front-end device input by the user and the time types of the input start time and end time are the standard time, the terminal may send the data query request to the server with 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 methods for standard time, one is UTC time, the other is UNIX timestamp, and the time of use of the terminal is X years, X months, X days, X minutes, X seconds. If the time type of the start time and the end time of the server storage data is UTC time and the time type of the start time and the end time input by the user on the terminal is UTC time, the terminal may directly use the start time and the end time input by the user as the first start time and the first end time, so that the time type of the first start time and the first end time is UTC time.

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

Compared with the prior art, the method for inquiring the data only supports the time zone time of the front-end equipment input by the user, the method for inquiring the data by providing the standard time input by the user improves the flexibility of inquiring the data.

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

The time period between the starting time and the ending time of the target data is a first time period, the first time period is included in the time period between the first starting time and the first ending 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 storage 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 one possible implementation, 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:

inquiring the stored data segments, time difference information corresponding to each data segment, and the starting time and the ending time of each data segment according to the identification of the front-end equipment, the first starting time and the first ending time;

For the server to store the data segment collected by the front-end device in step 402, when 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 during the query of the target data, the server may return the data as a query result to the terminal. In addition, when the server queries the target data, the server may also query 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 a start time and an 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 starting time and the ending 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 starting time and the ending time of the target data, the terminal converts the starting time and the ending time of the target data into second starting time and second ending time according to the first time difference information, wherein the time types of the second starting time and the second ending time are the time zone time of the front-end equipment.

The second start time is a time when the front-end equipment starts to collect the target data, and the second end time is a time when the front-end equipment ends to collect the target data.

In the embodiment of the invention, when a user inquires data, the data collected by the front-end equipment in the local time zone time is expected to be seen, so that the events of different time zones in a certain time period can be known. Because the time types of the start time and the end time of the target data returned by the server are standard time, in order to inform the user of the local time zone time of the front-end equipment when the target data is collected, the terminal can also determine the local time zone time when the front-end equipment collects the target data after receiving the target data returned by the server. And the first time difference information indicates a time difference between the time zone time when the front-end device acquired the target data and the standard time. Therefore, the terminal can convert the starting time and the ending 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 time type of the start time and the end time of the server storage data is UTC time, that is, the start time and the end time of the target data are UTC time, the terminal needs to convert the UTC time into the time zone time of the front-end device, for example, the terminal may convert the UTC time into the time zone time of the front-end device through the SDK interface, thereby obtaining the second start time and the second end time.

If the time type of the start time and the end time of the server storage data is a UNIX time stamp, that is, the start time and the end time of the target data are UNIX time stamps, the terminal needs to convert the UNIX time stamp into the time zone time of the front-end device, for example, the terminal may convert the UNIX time stamp into the time zone time of the front-end device through the SDK interface, thereby obtaining the second start time and the 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, after receiving the target data sent by the server, the terminal can display the target data. In addition, the terminal can display the local time zone time, namely the second starting time and the second ending time, when the front-end equipment collects the target data, so that the user can know the starting time and the ending time of the front-end equipment for collecting the data, and further know the event occurring in the collecting range of the front-end equipment in the time period.

Optionally, when the terminal displays the target data and 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 the user may learn a time difference between a time zone time of the front-end device 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 the data management of the terminal, the server and the front-end equipment under different time zone strategies. In particular, the front-end device access supporting multiple time zones, such as the encoder 1 of the front-end device 1 in the east two zone and the encoder 2 of the front-end device 2 in the east eight zone. When the data control operation is performed, the system automatically recognizes that the local time of the east two area is adopted for the front-end equipment 1 to perform the query, playback and download operation, and the local time of the east eight area is adopted for the front-end equipment 2 to perform the 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, if the time zone of the encoder 1 of the front-end device 1 in 1 month is the east two zone, and the time zone is changed into the east three zone in 2 months due to human factors, when the data control operation is performed, the time zone difference of different time periods is automatically identified in the system, and corresponding inquiry, playback and downloading 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 in addition to the data.

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

802. The server acquires data from the front-end equipment and stores the data.

Steps 801 to 802 are the same as steps 401 to 402, and are not described here.

803. When the input identification of the front-end equipment, the third starting time and the third ending time are acquired, the terminal sends a time difference inquiry 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 equipment.

The time difference inquiry request carries an identifier of the front-end equipment, the third starting time and the third ending time, and is used for acquiring time difference information of the front-end equipment in a time period corresponding to the third starting time and the third ending time, wherein the time difference information is used for indicating a time difference between time zone time of the front-end equipment in the time period and standard time.

In the embodiment of the invention, the user can input the identification of the front-end equipment to be queried and the query time period on the terminal, wherein the starting time and the ending time of the query time period adopt the local time zone time of the front-end equipment, namely, the third starting time and the third ending time. Because the time of the server bottom layer data is the 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 performs the data query operation after converting the starting time and the ending 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 identifiers, the third start time and the third end time 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 invoke the SDK interface to communicate with the server, and send a time difference query request to the server.

804. When receiving the time difference inquiry request of the terminal, the server acquires second time difference information of the front-end equipment 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 equipment in the second time period and the standard time.

In one possible implementation, the process of obtaining the second time difference information by the server may include: and according to the third starting time and the third ending time, inquiring a time zone information table 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 after the server obtains the time difference information in the second time period by querying the time zone information table, the server may return the obtained time difference information to the terminal.

805. 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, wherein 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 one 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 storage data is UTC time, 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 UTC time, for example, the terminal may convert the time zone time of the front end device into UTC time through the SDK interface, and the converted time is taken as the first start time and the first end time.

If the time type of the start time and the end time of the server storage data is a UNIX timestamp, since the time type of the third start time and the third end time is a 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 a UNIX timestamp, for example, the terminal may convert the time zone time of the front end device into a UNIX timestamp through the SDK interface, and the converted time is taken as the first start time and the first end time.

Further, in the same manner as step 403, since the first start time and the first end time are standard times, which are the same as the type of time when the server stores data, 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 to perform data query.

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

808. When receiving the target data, the first time difference information and the starting time and the ending time of the target data, the terminal converts the starting time and the ending time of the target data into second starting time and second ending time according to the first time difference information, wherein the time types of the second starting time and the second ending 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.

Steps 806 to 809 are similar to steps 404 to 407, and are not described herein.

The above steps 803 to 809 are data query processes for the case where 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 provided in 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 scheme provided by the embodiment of the invention, the server can support the access of a plurality of front-end devices, the plurality of front-end devices can be in different time zones, and the time zones of the same front-end device in different time periods can also be different. The time difference information of each front-end device in each time period is stored in the server in advance, 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 a user can be obtained from the server, and further, the time zone time of the front-end device is converted into standard time according to the time difference information returned by the server, and then the data inquiry operation is performed.

The technical scheme simultaneously supports the data management of the terminal, the server and the front-end equipment under different time zone strategies. In particular, the front-end device access supporting multiple time zones, such as the encoder 1 of the front-end device 1 in the east two zone and the encoder 2 of the front-end device 2 in the east eight zone. When the data control operation is performed, the system automatically recognizes that the local time of the east two area is adopted for the front-end equipment 1 to perform the query, playback and download operation, and the local time of the east eight area is adopted for the front-end equipment 2 to perform the query, playback and download operation.

It can be seen that the server may 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 equipment on the terminal, the time of the data returned by the query result is the time zone time of the front-end equipment, and the specific process is shown in the embodiment corresponding to fig. 8.
