Detailed Description
The technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention.
Example one
Referring to fig. 1, it shows a method for clock synchronization provided by an embodiment of the present invention, where the method is applied to a server, and the method includes:
step 101: receiving a time zone ID of the position of the household appliance and a first timestamp of the household appliance, which are sent by the household appliance;
step 102: updating a time synchronization period according to a preset time interval and a time zone ID of the position of the household appliance and a first timestamp of the household appliance;
step 103: and sending the second time stamp of the server according to the updated time synchronization period.
In the embodiment of the invention, the server updates the time synchronization period according to the time zone ID of the position of the household appliance sent by the household appliance and the first timestamp of the household appliance and sends the second timestamp of the server according to the updated time synchronization period, so that the time synchronization period of the server and the household appliance is dynamically adjusted, the phenomenon that the household appliance occupies too much resources due to too low time synchronization period setting is avoided, and the problem that the time accuracy of the household appliance cannot be ensured due to too high time synchronization period setting is avoided.
Specifically, updating the time synchronization cycle according to the time zone ID of the location of the home appliance and the first timestamp of the home appliance at a preset time interval includes:
determining a third timestamp of the server according to the time zone ID of the position of the household appliance;
determining a time difference value according to the third timestamp of the server and the first timestamp of the household appliance;
and updating the time synchronization period according to the time difference.
It should be noted that the time zone ID of the location of the home device is used to identify the time zone name of the location of the home device. The time zone ID and time zone name are one-to-one. For example: the home device is in california, and 911 may be used as the california identification, and 911 is the time zone ID of the california, where the home device is located.
The first timestamp of the home device is a time displayed by a clock of the home device, and the time may be inaccurate due to hardware of the home device, software of the home device, or movement of the home device. The time synchronization period is used for enabling the clock display time of the household appliance to be consistent with the time of the position of the household appliance determined by the server. During specific implementation, the server sends the second timestamp of the server to the household appliance according to the time synchronization period, and the household appliance updates the clock time according to the second timestamp of the server.
In specific implementation, the server needs to pre-store a mapping table of time zone ID and time zone name. Based on the mapping table of the time zone ID and the time zone name, when the household appliance reports the time zone ID of the position of the household appliance to the server, the server determines the time zone name of the position of the household appliance according to the time zone ID of the position of the household appliance, and further determines the accurate time of the position of the household appliance, namely the third timestamp of the server, according to the time zone name of the position of the household appliance. It should be noted that the determining of the third timestamp of the server is triggered based on the time zone ID of the location where the home appliance is reported by the home appliance and the first timestamp of the home appliance.
According to the embodiment of the invention, the time difference value is determined according to the first time stamp of the household appliance and the third time stamp of the server. For example: the first timestamp of the home device is 12: 00, the third timestamp of the server is 12:03, so that the inaccuracy of the clock time of the household appliance can be judged, and the time difference value is further calculated to be 00: 03. Since the time deviation of the home device may be different at different time periods, which may cause a time difference between the first time stamp of the home device and the third time stamp of the server to be different, the time synchronization period needs to be updated according to the determined time difference. For example, the following steps are carried out: in month 1, the time deviation of the household appliance is 1 hour, so that the time difference value between the first time stamp of the household appliance and the third time stamp of the server is 1 hour, and the time synchronization period is 1 hour; and in month 7, the time deviation of the home device is 30 minutes, so that the time difference between the first time stamp of the home device and the third time stamp of the server is 30 minutes, and the update time synchronization period is 30 minutes.
When the first timestamp of the home appliance is not equal to the third timestamp of the server, it indicates that the clock time of the home appliance is not accurate, and therefore the home appliance and the server need to be time-synchronized, based on which, the technical scheme shown in fig. 1 further includes: and when the first timestamp of the household appliance is not equal to the third timestamp of the server, sending the third timestamp of the server.
It can be understood that the third timestamp of the server is the time zone time of the location of the home appliance determined by the server according to the time zone ID of the location of the home appliance, so when it is determined that the clock of the home appliance has a deviation, the third timestamp of the server needs to be immediately sent in order to improve the time accuracy of the home appliance. It should be noted that the third timestamp of the sending server is event-triggered and is not limited by the time synchronization period.
Corresponding to the case that the first timestamp of the home device is not equal to the third timestamp of the server, the technical solution shown in fig. 1 further includes:
adding the time difference value to a time difference value recording table corresponding to the time difference value being smaller than a preset deviation threshold value;
and determining that the position of the household appliance is obviously changed corresponding to the time difference value being larger than a preset deviation threshold value.
It should be noted that the preset deviation threshold is determined by the server according to the specific device parameters of the home device. The preset deviation threshold is an upper limit value of time deviation caused by software or hardware of the household appliance. Different home appliances may have different time deviation ranges due to hardware or software, so different deviation thresholds need to be set.
It can be understood that when the time difference between the first time stamp of the home appliance and the third time stamp of the server is greater than the preset deviation threshold, it indicates that the time deviation of the home appliance exceeds the upper limit value of the time deviation caused by software or hardware of the home appliance, and thus it can be determined that the time deviation of the home appliance is not caused by software or hardware of the home appliance, and it is further determined that the location of the home appliance is changed greatly.
When the time difference between the first time stamp of the home appliance and the third time stamp of the server is smaller than the preset deviation threshold, it is indicated that the time deviation of the home appliance does not exceed the time deviation upper limit value caused by software or hardware of the home appliance, so that it can be determined that the time deviation of the home appliance is caused by the software or hardware of the home appliance, and at this time, the time deviation needs to be recorded into the time difference recording table. The time difference recording table records a plurality of time differences generated by the household appliance.
The time difference record table is used to determine a time synchronization period between the server and the home appliance, and based on this, in the technical solution shown in fig. 1, updating the time synchronization period according to the time difference includes:
determining a minimum time difference value in a preset time interval in the time difference value recording table;
and updating the time synchronization period according to the minimum time difference value.
The server sends the second timestamp of the server to the home device according to the time synchronization cycle. The second timestamp of the server is the time of the home device location determined by the server. Therefore, the second timestamp of the server is sent periodically.
It can be understood that, since the minimum time difference represents the minimum time deviation of the home appliance, in order to timely time synchronize the home appliance, the home appliance and the server may be time synchronized according to the minimum time deviation. In the embodiment of the invention, the minimum time difference value is determined from the time difference value recording table, and the time synchronization of the server and the household appliance is carried out according to the minimum time difference value. Since the minimum time difference values in different time periods may be different, a time interval is preset to improve the time accuracy of the home appliance. And determining a minimum time difference value in a preset time interval, and updating the time synchronization period according to the minimum time difference value. And the server sends the second timestamp of the server to the household appliance according to the updated time synchronization period. Preferably, the predetermined time interval is three months. For example, the following steps are carried out: from month 1 to month 3, the following time difference values are recorded in the time difference value recording table: 01:00, 00:30, 00: 25; from month 4 to month 6, there are the following time difference values in the time difference value recording table: 00:40, 01:03, 00:15. This can result in: the minimum time difference value from 1 month to 3 months is 00:25, the minimum time difference value from 4 months to 6 months is 00:15, further, 3 months to 6 months are determined, the time synchronization period of the household appliance and the server is 25 minutes, and after 6 months, the time synchronization period of updating the household appliance and the server is 15 minutes.
According to the embodiment of the invention, the server updates the time synchronization period according to the time deviation of the household appliance, and the time synchronization periods of the server and the household appliance are adjustable, so that the problem that the accuracy of the clock of the household appliance cannot be ensured due to overhigh time synchronization period setting can be avoided, and the problem that the household appliance occupies too much resources due to overlow time synchronization period setting can be avoided.
Example two
Based on the same inventive concept of the foregoing embodiment, referring to fig. 2, a method for clock synchronization provided in an embodiment of the present invention is shown, and the method can be applied to a home appliance, and the method includes the following steps:
step 201: sending a time zone ID of the position of the household appliance and a first timestamp of the household appliance according to a preset first time period;
step 202: receiving a second timestamp of the server;
step 203: and updating the clock time of the household appliance from the first time stamp of the household appliance to the second time stamp of the server.
According to the embodiment of the invention, the household appliance sends the time zone ID of the position of the household appliance and the first timestamp of the household appliance to the server according to the preset first time period, and the household appliance receives the second timestamp of the server and updates the clock time of the household appliance to be the second timestamp of the server. Therefore, the effect of improving the clock accuracy of the household appliance can be achieved.
It should be noted that the home appliance described in the embodiment of the present invention has a real-time clock, and can normally operate depending on a battery when the power is off, and can remotely communicate with a server to perform mutual communication.
The first timestamp of the household appliance is the time displayed by a clock of the household appliance, and the time zone ID of the position of the household appliance is sent by the control terminal device, so that the method further comprises the following steps before sending the time zone ID of the position of the household appliance and the first timestamp of the household appliance according to the preset first time period:
and receiving the time zone ID of the position of the household appliance sent by the control terminal equipment.
In a specific implementation, the home device needs to store the time zone ID of the location of the home device, so as to send the time zone ID of the location of the home device according to the first time period.
Based on the third timestamp of the server sent by the server, the technical solution shown in fig. 2 further includes:
receiving a third timestamp of the server;
and updating the clock time of the household appliance from the first time stamp of the household appliance to the third time stamp of the server.
It can be understood that, in the first embodiment of the present invention, it has been described that the server sends the third timestamp of the server based on that the first timestamp of the home device is not equal to the third timestamp of the server, and based on that, the home device receives the third timestamp of the server. The server sends the third timestamp of the server to indicate that the clock time of the home appliance is inaccurate, so that after the home appliance receives the third timestamp of the server, the clock time of the home appliance needs to be updated from the first timestamp of the home appliance to the third timestamp of the server.
In the embodiment of the invention, the household appliance updates the clock time according to the second timestamp of the server. Therefore, the effect of improving the clock accuracy of the household appliance can be achieved.
EXAMPLE III
Based on the same inventive concept of the foregoing embodiment, referring to fig. 3, a method for clock synchronization provided in an embodiment of the present invention is shown, and the method can be applied to control a terminal device, and the method includes the following steps:
step 301: determining the time zone ID of the position of the household appliance according to a preset mapping table of the time zone name and the time zone ID;
step 302: and sending the time zone ID of the position of the household appliance to the household appliance.
It should be noted that, in the embodiment of the present invention, the control terminal device may communicate with the server, may remotely control the home appliance device, and may transmit the instruction to the home appliance device in real time.
When the embodiment of the invention is specifically realized, the control terminal device prestores the mapping table of the time zone name and the time zone ID. The user can select a time zone ID which is preset to the household appliance from a mapping table of the time zone name and the time zone ID through the control terminal device, the control terminal device remotely sends the time zone ID of the household appliance to the household appliance, or the control terminal device automatically acquires the time zone ID preset to the household appliance and remotely sends the time zone ID to the household appliance.
The embodiment of the invention can realize the effect of setting the time zone ID of the household appliance through the control terminal equipment.
Example four
Based on the same inventive concept of the foregoing embodiment, referring to fig. 4, a specific flow of a method for clock synchronization according to an embodiment of the present invention is shown, where the method may be applied to control a terminal device, a home appliance device, and a server, and the specific flow includes the following steps:
step 401: and the control terminal equipment determines the time zone ID of the position of the household appliance according to a preset mapping table of the time zone name and the time zone ID.
Step 402: and the control terminal equipment sends the time zone ID of the position of the household appliance to the household appliance.
Step 403: the household appliance sends the time zone ID of the position of the household appliance and the first timestamp of the household appliance to the server according to a preset first time period.
In specific implementation, the time of the clock of the home appliance is the first timestamp of the home appliance.
Step 404: and the server receives the time zone ID of the position of the household appliance and the first timestamp of the household appliance, which are sent by the household appliance.
Step 405: and the server determines the time zone name of the position of the household appliance according to a preset time zone name and a mapping table of the time zone ID based on the time zone ID of the position of the household appliance.
It will be appreciated that the server needs to pre-store a mapping table of time zone names to time zone IDs. The mapping table includes all time zone names around the world and the corresponding time zone IDs.
Step 406: and the server determines the precise time of the position of the household appliance according to the name of the time zone in which the household appliance is positioned, namely the third timestamp of the server.
Step 407: the server compares the third timestamp of the server with the first timestamp of the home appliance device, if the third timestamp of the server is not equal to the first timestamp of the home appliance device, the third timestamp of the server is sent to the home appliance device, and the step 408 is skipped; if equal, the process ends.
Step 408: and the server calculates the time difference value of the third time stamp of the server and the first time stamp of the household appliance. When the time difference is larger than a preset deviation threshold value, determining that the position of the household appliance is changed greatly; and when the time difference is smaller than a preset deviation threshold value, recording the time difference to a time difference recording table.
Step 409: and the server determines the minimum time difference value in the time difference value record table according to the preset time interval, and updates the time synchronization period to be the minimum time difference value.
Step 410: and the server sends the second timestamp of the server to the household appliance according to the updated time synchronization period.
It is understood that the time synchronization between the server and the home device is performed by transmitting the second timestamp of the server to the home device according to the time synchronization period. The second timestamp of the server is the exact time of the home device as determined by the server based on the location of the home device.
The time zone ID of the household appliance is determined through the control terminal, and the household appliance sends the time zone ID of the position where the household appliance is located and the first timestamp of the household appliance to the server according to the preset period. And the server determines an updated time synchronization period according to the time zone ID of the position of the household appliance and the first time of the household appliance, and sends a second timestamp of the server according to the updated time synchronization period. Based on the above, the embodiment of the invention realizes the effect of dynamically adjusting the time synchronization period, can avoid the problem that the accuracy of the clock of the household appliance cannot be ensured due to overhigh time synchronization period setting, and can avoid the problem that the household appliance occupies too much resources due to overlow time synchronization period setting.
