In order to ensure the available time of the device after power failure as much as possible, a general method is to preferentially turn off a peripheral with high power consumption, such as an SSD (Solid State Disk), after delaying for a relatively short time (e.g., 1 s). If there is data currently flowing to the SSD to write data, the data may be incomplete, resulting in abnormal service, and even damaging the SSD.
In the related technology, processing is performed on an application layer, specifically, all data transmission is immediately stopped after the device is sensed to be powered down, and if the device is powered down in the transaction transmission process, transaction data rollback is performed after the device is started. However, application layer processing can greatly increase the complexity of business logic, and targeted transaction rollback logic needs to be developed for each critical transaction, and this logic needs to be added for each application layer service involving business data.

Detailed Description
For the purpose of better explaining the present invention and to facilitate understanding, the present invention will be described in detail by way of specific embodiments with reference to the accompanying drawings.
According to the electronic equipment and the power failure protection method, device and storage medium thereof provided by the embodiment of the invention, when the electronic equipment is abnormal in system power failure, current service data are obtained; and temporarily storing the current service data into the system data area so as to store the current service data temporarily stored into the system data area into the service data area when the power supply of the electronic equipment is restored, wherein the availability of the mutually separated system data areas is higher than that of the service data area. Therefore, on the basis of the separation of the system data area and the service data area and under the condition that the availability of the system data area is higher than that of the service data area, the service data is cached in the system data area firstly to ensure the atomization completion of the current transaction, and the service data cached in the system data area is automatically and timely recovered to the service data area after the equipment is started and recovered, so that the problem of incomplete data when the equipment is powered off is thoroughly solved from the basic characteristic level of independence of the service, and the transaction fault-tolerant processing logic of an application layer is greatly reduced.
In order to better understand the above technical solutions, exemplary embodiments of the present invention will be described in more detail below with reference to the accompanying drawings. While exemplary embodiments of the invention are shown in the drawings, it should be understood that the invention can be embodied in various forms and should not be limited to the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be thorough and complete, and will fully convey the scope of the invention to those skilled in the art.
Fig. 1 is a flowchart of a power down protection method of an electronic device according to an embodiment of the present invention, and as shown in fig. 1, the power down protection method of the electronic device includes the following steps:
step S102, when the system power failure abnormality occurs in the electronic equipment, current service data is obtained.
And step S104, temporarily storing the current service data into the system data area so as to store the current service data temporarily stored into the system data area into the service data area when the power supply of the electronic equipment is restored.
It should be noted that, in the present application, the electronic device includes a system data area and a service data area that are separated from each other, and the availability of the system data area is higher than that of the service data area. The system data area refers to a non-lost device for storing system-related data, such as a non-lost memory like an EMMC, and the service data area refers to a non-lost device for storing user-related data, such as a non-lost memory like an SSD; the availability of the system data area is higher than that of the service data area, namely the power supply time of the system data area is longer than that of the service data area based on the consideration of power consumption. That is, the data area of the device is divided into a system data area and a service data area, and after power failure, the power supply duration of the system data area is longer than that of the service data area.
In the working process of the electronic device, when the system power failure abnormality occurs in the electronic device, a simple power backup system, such as a capacitor, a backup battery, and the like, in the electronic device starts to supply power to the electronic device, for example, the system data area and the service data area are continuously supplied with power for a period of time, and the power supply time for the system data area is longer than the power supply time for the service data area, for example, the power supply time for the service data area is 3s, and the power supply time for the system data area is longer than 3s (it should be noted that the time is enough to store the current service data in the system data area when the system power failure occurs). In the power supply time, the system acquires current business data and temporarily stores the current business data into a system data area to ensure the atomization completion of the business, then when the electronic equipment recovers power supply, the current business data in the system data area is automatically identified and recovered to the business data area, so that the problem of incomplete data after the equipment is powered down can be solved from a system layer, the business can be completely and normally completed on the equipment, and the application layer service does not need to process the business rollback logic, namely does not need to sense the equipment which is very sensitive to the application layer to be powered down, and further can inform the equipment of the power down when the next business request is carried out.
In the example, based on the separation of the system data area and the service data area, and the condition that the availability of the system data area is higher than that of the service data area, the service data is cached in the system data area first to ensure the atomization completion of the current transaction, and the service data cached in the system data area is automatically and timely recovered to the service data area after the equipment starts and recovers, so that the problem of incomplete data existing when the equipment is powered off is thoroughly solved from the basic characteristic level of independence of the service, and the transaction fault-tolerant processing logic of the application layer is greatly reduced.
Fig. 2 is a flowchart of a power down protection method of an electronic device according to another embodiment of the present invention, as shown in fig. 2, the power down protection method of the electronic device includes the following steps:
step S202, when the system power failure abnormality occurs in the electronic equipment, the current service data is obtained, and the structured service data request is determined.
Step S204, the structured service data request and the current service data are temporarily stored in the system data area.
It should be noted that the structured data is also called row data, is data logically expressed and implemented by a two-dimensional table structure, strictly follows data format and length specification, is mainly stored and managed by a relational database, and is non-structured data which is not suitable for being expressed by a two-dimensional table, including office documents, XML, HTML, various types of reports, pictures and audio and video information, etc. in all formats, as opposed to the structured data. In the application, in order to store structured and unstructured service data into a system data area when system power failure abnormality occurs in the electronic device, and simultaneously, quickly and accurately restore the service data temporarily stored in the system data area into the service data area when the power supply of the electronic device is restored, current service data can be received, a structured service data request can be determined, and the structured service data request and the current service data can be temporarily stored into the system data area together when the system power failure abnormality occurs in the electronic device.
Optionally, the temporarily storing the structured service data request and the current service data into the system data area includes: and determining the service data which is not stored in the service data area in the current service data according to the structured service data request, and temporarily storing the structured service data request and the service data which is not stored in the service data area in the current service data into the system data area. That is to say, when a system power failure abnormality occurs in the device during service data transmission, a part of service data before power failure is already stored in the service data area, and another part of service data after power failure is not yet stored in the service data area, at this time, the service data which is not stored in the service data area can be determined according to the structured service data request, and the structured service data request and the service data which is not stored in the service data area in the current service data are temporarily stored in the system data area.
And step S206, when the power supply of the electronic equipment is recovered, analyzing the structured service data request, obtaining the storage information of the current service data, and storing the current service data into a service data area according to the storage information.
Specifically, after the power failure and power restoration of the electronic device, the service data temporarily stored in the system data area is restored to the service data area, specifically, the storage information of the service data is obtained by analyzing the structured service data request, and then the service data in the system data area is stored in the service data area according to the storage information, so that the data is quickly and accurately restored to the service data area.
Optionally, saving the current service data to the service data area according to the storage information includes: and according to the storage information, the service data which is not stored in the service data area in the current service data is continuously stored in the service data area. That is, after the electronic device is powered off and power is restored, the structured service data request can be analyzed to obtain the storage information of the service data, and then the service data which is not stored in the service data area before in the system data area is continuously stored in the service data area according to the storage information.
Optionally, saving the current service data to the service data area according to the storage information includes: and determining the service data which is already stored in the service data area when the system is abnormal in power failure in the current service data according to the storage information, and covering the service data which is already stored in the service data area when the system is abnormal in power failure in the current service data according to the current service data. It should be noted that, in this example, when a system power failure abnormality occurs in the device, the current service data (including the service data already stored in the service data area and the service data not stored in the service data area) and the structured service data request are stored in the system data area together, after the power of the device is restored, the structured service data request is analyzed to obtain the storage information of the current service data, and then the current service data is all stored in the service data area according to the storage information, at this time, the service data stored in the service data area when the power failure abnormality occurs will be covered by the service data temporarily stored in the system data area.
In the above example, based on the structured service data request, when the electronic device is abnormal due to system power failure, the structured and unstructured service data can be stored in the system data area, and meanwhile, when the electronic device recovers power supply, the service data temporarily stored in the system data area can be quickly and accurately recovered to the service data area. Meanwhile, the service data temporarily stored in the system data area can be restored to the service data area by adopting a continuous storage mode or a coverage mode, so that the flexibility of data restoration is improved.
It should be noted that, during the service data recovery period, different manners may be adopted to ensure the sequentiality of the service data, and may be specifically selected according to the service condition.
As a mode, when the electronic device resumes power supply, the received new service data request is further stored in the system data area, and is arranged after the data request corresponding to the current service data, until the current service data temporarily stored in the system data area is stored in the service data area, the new service data request is acquired, and the corresponding service data is stored in the service data area according to the new service data request. That is to say, after the power supply of the electronic device is restored, if a new service data request exists, the new service data request is stored in the system data area, and is located after the service data request corresponding to the current service data temporarily stored in the system data area, until the current service data temporarily stored in the system data area is restored to the service data area, the new service data request is obtained, and the corresponding service data is stored in the service data area according to the new service data request.
As another mode, when the electronic device resumes power supply, the receiving of all service data requests is suspended until the current service data temporarily stored in the system data area is stored in the service data area. That is, after the power supply of the electronic device is resumed, if there is a new service data request, the receiving of all service data requests may be suspended, and error codes "data repair, please wait" are provided to the outside in a unified manner until the current service data temporarily stored in the system data area is stored in the service data area, and then the new service data request starts to be received, and the corresponding service data is stored in the service data area according to the new service data request.
In the above example, during the data recovery, the sequence of the service data can be ensured by storing the received new service data request into the service data area or suspending the reception of all service data requests until the current service data temporarily stored in the system data area is stored into the service data area, and then storing the corresponding service data into the service data area according to the new service data request.
In some embodiments, a power down protection method for an electronic device further includes: and when the power supply of the electronic equipment is normal, directly storing the service data into the service data area. Namely, when the power supply of the electronic equipment is normal, the current service data is directly stored in the service data area.
Fig. 3-4 are schematic diagrams illustrating data storage of an electronic device according to an embodiment of the present invention, in this example, a caching logic layer is added, and a system-in-package layer writes a service data request. As shown in fig. 3, when the power supply of the electronic device is normal, the cache logic layer directly stores the service data into the service data area after receiving the service data sent by the application layer, and receives the feedback information of the service data area after the data storage is completed, and transmits the feedback information to the application layer. When the system power failure of the electronic equipment is abnormal, the cache logic layer determines a structured service data request, stores the structured service data request and the service data into the system data area, receives feedback information of the system data area after the data storage is finished, and transmits the feedback information to the application layer.
As shown in fig. 4, when the electronic device is powered off and power is restored, the cache logic layer starts and performs a data restoration service, and if the system data area has a structured service data request, the cache logic layer first obtains the structured service data request and the service data from the system data area, and after the data is successfully obtained, parses the structured service data request, and stores the service data into the service data area according to the structured service data request, and receives feedback information that the data in the service data area is successfully stored after the data is completely stored.
Further, in fig. 4, during the data recovery period, if new service data needs to be stored in the service data area, the received new service data request may be stored in the service data area or all the service data requests may be suspended from being received until the current service data temporarily stored in the system data area is stored in the service data area, and then the corresponding service data is stored in the service data area according to the new service data request, which may be specifically selected according to the service condition.
In summary, the power-fail protection method for electronic equipment provided in the embodiments of the present invention is based on the condition that the system data area is separated from the service data area, and the availability of the system data area is higher than that of the service data area, the service data is cached in the system data area first to ensure that the atomization of the current transaction is completed, and the service data cached in the system data area is automatically and timely restored to the service data area after the start and restoration of the equipment are completed, so that the problem of incomplete data when the equipment is powered down is thoroughly solved from the basic characteristic level of independence of the service, and the transaction fault-tolerant processing logic of the application layer is greatly reduced.
