Description
Technical Field
The invention relates to the technical field of computers and software thereof, in particular to a method for realizing business data consistency between an intelligent electric appliance and a cloud end and the intelligent electric appliance keeping the business data consistency with the cloud end.
Background
In a modern intelligent hardware system, intelligent hardware data (such as device state and service data) generally exists at a hardware (device) end, and is stored at an intelligent cloud end (server end) so that a user can use the data when the device is offline (namely, disconnected from the network and not connected with the cloud end). For example, a user may set a recipe of a smart microwave oven through a mobile phone APP (application), the recipe data is first sent to the cloud, the cloud sends the recipe data to a smart device (hardware end), and the cloud stores the recipe data. In addition, the user can also directly set the service data on the intelligent device, and then the set service data is reported to the cloud, and the user can view and maintain the service data (such as menu data) on the mobile phone APP.
The problem of distributed data storage, namely the problem of inconsistent data of the cloud and the intelligent device, is solved in the above usage scenarios. For example, the user sets the service data at the cloud end, the cloud end issues the service data to the intelligent device, the intelligent device receives the service data successfully, but the time is out when the response is given to the cloud end, then the cloud end can inform the user that the issuing of the service data to the intelligent device end fails, the user may withdraw the operation, accordingly, the cloud end can discard the service data, but the intelligent device already stores the service data, and thus, the data at the cloud end and the data at the intelligent device end are inconsistent.
Generally, the distributed data inconsistency of the system is easily caused due to the complexity of the intelligent hardware network environment. The current technical scheme does not support data synchronization of two ends generally, and generally, data is subject to a hardware end (an intelligent device end), and a cloud end only stores data backup or pulls a device snapshot from the hardware end (the intelligent device end). Due to the fact that the data of the cloud end and the data of the two ends of the intelligent device end are asynchronous, user experience is poor.

Detailed Description
Exemplary embodiments of the present invention are described below with reference to the accompanying drawings, in which various details of embodiments of the invention are included to assist understanding, and which are to be considered as merely exemplary. Accordingly, those of ordinary skill in the art will recognize that various changes and modifications of the embodiments described herein can be made without departing from the scope and spirit of the invention. Also, descriptions of well-known functions and constructions are omitted in the following description for clarity and conciseness.
Fig. 1 is a schematic diagram illustrating main steps of a method for implementing business data consistency between an intelligent appliance and a cloud according to an embodiment of the present invention.
The method for realizing the business data consistency between the intelligent electric appliance and the cloud end mainly comprises the steps S11 to S13. The service data comprises data content, a data source and a version number.
Step S11: when a user sets or updates service data in the intelligent electric appliance, the intelligent electric appliance executes the following actions: and if the data source is initially set, setting the version number to be 0, otherwise, increasing the version number by 1, setting the data source as the intelligent electrical appliance, and storing the set or updated service data.
Step S12: when a user sets or updates service data in the cloud, the cloud executes the following actions: and if the set service data is the initial set service data, setting the version number as 0, otherwise, increasing the version number by 1, setting the data source as a cloud, and sending the set or updated service data to the intelligent electric appliance, wherein when the sending is successful, the intelligent electric appliance receives and stores the set or updated service data.
When the cloud sends the set or updated data to the intelligent electric appliance, if the sending is unsuccessful, the cloud rolls back the data.
Step S13: when the intelligent electric appliance is connected with the cloud end, the intelligent electric appliance sends a snapshot of the stored business data to the cloud end according to the set frequency, the snapshot comprises a data source and a version number of the business data stored by the intelligent electric appliance, and the cloud end compares the received snapshot with the business data stored by the cloud end to judge consistency.
When the data source and the version number of the received snapshot are the same as those of the service data stored in the cloud, the data are judged to be consistent, when the data source is the same and the version number is different, the current service data of one of the intelligent electric appliance and the cloud corresponding to the data source is used for updating the service data of the other one, and when the data source is different, the service data of the other one is updated by the service data of the intelligent electric appliance and the cloud with the larger version number of the current service data.
The user, the smart appliance and the cloud may communicate with each other in a wired or wireless manner.
The user can access the intelligent electric appliance or the cloud end through the Internet by utilizing the client equipment and set or update the business data, and particularly, the user can set or update the business data in the intelligent electric appliance or the cloud end by utilizing the mobile phone APP.
The user can also set or update the service data on the input device of the intelligent electric appliance.
Fig. 2 is a schematic diagram illustrating data interaction among a user side, an intelligent appliance side, and a cloud side according to an embodiment of the present invention. The user side can be a mobile phone APP. The intelligent electric appliance can be an electric appliance such as a microwave oven, a refrigerator, a washing machine, an air conditioner, an electric curtain and the like with a processing device (processor) and a communication function.
The data interaction among the user side, the smart appliance side and the cloud side is described in detail below according to the interaction diagram shown in fig. 2.
The user can set or update the business data at the cloud end through the user sides such as the mobile phone APP, for example, the user can set or update the business data at the mobile phone APP interface, and then upload the business data to the cloud end for storage. The cloud sets the data source as the cloud while storing the service data set or updated by the user, and accumulates the version number of the service data in the cloud by 1, specifically, the cloud may preset an initial value of the version number of the service data, for example, 0, and when the service data in the cloud is updated, the updated version number of the service data is accumulated by 1 on the basis of the original version number. And then, the cloud sends the updated service data to the intelligent electric appliance end, if the cloud sends the data successfully, the intelligent electric appliance end stores and updates the service data, meanwhile, the version number of the updated service data per se is also accumulated by 1, and if the cloud sends the data unsuccessfully, the cloud rolls back the data, namely, the cloud recovers the service data before updating. For example, assume that the service data is air conditioner temperature data, the air conditioner temperature that the current cloud was saved is 20 degrees celsius, and the data version number is 1, when the user sets the air conditioner temperature at the cloud to 30 degrees celsius through APP or the like, then the air conditioner temperature that the cloud was stored is updated to 30 degrees celsius, and the version number becomes 2, the cloud issues the updated air conditioner temperature data, if the issuance fails, then the cloud performs data rollback, that is, the saved air conditioner temperature is restored to the original 20 degrees celsius, and the original version number 1 is replied. The failure issue condition may be that the cloud does not issue the data to the intelligent electrical appliance end due to a network reason, or that the cloud has issued the data to the intelligent electrical appliance end and the intelligent electrical appliance end has successfully updated the data, but the cloud does not receive a functional response returned by the intelligent electrical appliance end due to a network flash and the like, so that the cloud considers the failure issue of the data.
The user may also directly operate the smart appliance to set or update the service data, for example, the user directly sets or updates the service data on an input device (e.g., an operation panel) of the smart appliance and stores the service data. The intelligent electric appliance sets the data source as the intelligent electric appliance while storing the service data set or updated by the user, and adds 1 to the version number of the service data at the intelligent electric appliance end. Then, the smart appliance determines whether to report the updated service data to the cloud end according to the online condition (i.e. the condition of establishing communication connection with the cloud end), and if the smart appliance is online (i.e. the condition of establishing communication connection with the cloud end), the service data is reported to the cloud end, otherwise, the service data is reported again when waiting to be online.
Under a certain condition, for example, if data transmission by the cloud fails or data reporting by the intelligent electrical appliance fails, the two-end data is inconsistent, and therefore, the problem of consistency of the two-end data is solved between the intelligent electrical appliance and the cloud based on a data snapshot reporting mechanism. The mechanism does not pursue strong consistency of the two-end data (namely real-time consistency of the data), but mainly focuses on weak consistency of the data, namely, the two-end data can ensure final consistency of the data as long as the intelligent electric appliance is normally online.
The following describes a specific implementation method of the data snapshot reporting mechanism in detail. When the intelligent electric appliance is in communication connection with the cloud, the intelligent electric appliance uploads the snapshot of the currently stored business data to the cloud, and the snapshot can be reported regularly as long as the intelligent electric appliance is kept online (namely, is in communication connection with the cloud). The snapshot specifically includes a data source and a version number of the service data stored by the intelligent electrical appliance, and also includes specific contents of the service data. And the reporting snapshot can be reported at a set frequency, for example, every five minutes, the reported specific frequency is related to the device attribute of the intelligent electrical appliance, and the intelligent electrical appliance terminal can be customized. After the cloud receives the reported snapshot, the cloud compares the snapshot with the service data stored in the cloud to judge the consistency of the data of two ends (the intelligent electrical appliance end and the cloud end). Specifically, the data sources and the version numbers of the snapshot and the cloud service data are sequentially compared, and when the data sources and the version numbers of the snapshot and the cloud service data are the same, it is determined that the two end data are consistent. When the data sources are the same and the version numbers are different, the service data of the data sources are used as a standard, namely, if the service data are all from the cloud end, the cloud end issues the stored service data to the intelligent electric appliance again, so that the intelligent electric appliance updates the service data of the cloud end to be consistent with the cloud end, and if the service data are all from the intelligent electric appliance, the cloud end updates the service data of the cloud end according to the data in the snapshot so as to be consistent with the data of the intelligent electric appliance end. And when the data sources are different, comparing the version numbers of the service data of the snapshot and the cloud, and taking the version number higher of the two as the standard, namely updating the cloud service data if the version number of the service data in the snapshot is higher, otherwise, sending the data to the intelligent electric appliance by the cloud so as to update the service data in the intelligent electric appliance into the data consistent with the cloud.
Fig. 3 is a schematic diagram of main components of an intelligent appliance consistent with cloud-held business data according to an embodiment of the present invention. The service data comprises data content, a data source and a version number.

When the intelligent electrical appliance 30 is in communication connection with the cloud, the processing device 34 sends a snapshot of the stored service data to the cloud according to a set frequency, the snapshot includes a data source and a version number of the service data stored by the intelligent electrical appliance 30, wherein the cloud compares the received snapshot with the service data stored in the cloud to determine consistency, wherein when the received snapshot is the same as the data source and the version number of the service data stored in the cloud, the data is determined to be consistent, when the data source is the same and the version number is different, the service data of one of the intelligent electrical appliance 30 and the cloud corresponding to the data source is updated by using the current service data of the other one of the intelligent electrical appliance 30 and the cloud, and when the data source is different, the service data of the other one of the intelligent electrical appliance 30 and the cloud having the larger version number is updated by using the service data of the current service data of the other.
The communication device 32 may be used to enable wired or wireless communication with the cloud and the user.
