An embodiment of the present invention provides a data management method. Referring to FIG. 2 , FIG. 2 is a schematic flowchart of a first embodiment of the data management method of the present invention.

In this embodiment, the data management method includes the following steps:

Step S10: When receiving the data request information, determine whether there is matching data in the local storage area.

It should be noted that the execution subject of this embodiment may be a computing service device with data processing, network communication and program running functions, such as a tablet computer, a personal computer, a mobile phone, a wearable device, etc., or a device that can implement Electronic equipment, data management equipment, main system, etc. for the above functions. Hereinafter, the main system is taken as an example to illustrate this embodiment and the following embodiments.

It can be understood that the data request information may be information requesting to call data, the data request information includes data requests, and the number of data requests in the data request information is at least one; the local storage area may be allocated to the main system during hardware design Storage area; the matching data can be the data stored in the local storage area that matches the data request in the data request information, for example, if the data request in the data request information is a gyroscope data request, then the matching data is gyroscope data, where the data request It may also be a picture data request, an audio data request, etc., which are not limited in this embodiment.

In a specific implementation, when the host system receives the data request information, it determines the data request included in the data request information, and judges whether data matching the data request is stored in the local storage area allocated by the host system.

Step S20: If it does not exist, send the data request information to the corresponding slave system, and the data storage area of the slave system is divided into virtual file system partitions for storing multiplexed data of external systems.

It can be understood that the master system and the slave system can be determined according to the role in the process of accessing and operating the same storage area. The system partition requests data. For example, there are three systems A, B, and C. Suppose system A requests data from the data storage area of system B. At this time, data A can be called the master system, and system B can be called the slave system. Suppose system B Request data from the data storage area of system C. At this time, data B can be called the master system, and data C can be called the slave system; the data storage area can be the storage area allocated for the slave system during hardware design; external system multiplexing The data can be used by both the master system and the slave system; the virtual file system partition can be divided in the data storage system to store the storage partition of the virtual file system; since the operating state of the system is constantly changing, in order to adapt to the system Depending on the operating state, the size of the virtual file system partition can be dynamically adjusted according to the system operating state, for example, the amount of requested data within a preset historical time period can be determined, and the size of the virtual file system partition can be adjusted according to the amount of data.

Step S30: receiving the matching data searched by the slave system from the virtual file system partition according to the data request information.

It should be noted that, after receiving the data request in the data request information, the slave system searches for data matching the data request in the virtual file system partition according to the data request, and feeds the found data back to the master system.

In specific implementation, for example, the wearable device includes three systems, namely system A, system B and system C, system A is the main system, system B and system C are the slave systems of system A, and the data storage area of system B There is a virtual file system partition B1 for storing sensor data, and a virtual file system partition C1 for storing picture data in the data storage area of system C. The data request information received by system A includes picture data requests and sensor data requests. , in order to find the corresponding picture data and sensor data in the local storage area, system A sends the picture data request to system C, and sends the sensor data request to system B. After receiving the sensor data request, system B sends the virtual file System partition B1 searches for sensor data and feeds the found sensor data back to system A. After system C receives the request for picture data, it searches for picture data in virtual file system partition C1 and feeds back the found picture data to system A; the above The data is not limited to picture data and sensor data, but can also be audio data, video data, etc. The above-mentioned picture data and sensor data can also be stored in system B or system C at the same time. At this time, it is only necessary to request data from system B or system C. Yes, this embodiment is not limited here.

Further, in order to improve the request efficiency of important data, the sending the data request information to the corresponding slave system includes: determining the request priority of each data request in the data request information; The data requests are sequentially sent to corresponding slave systems.

It can be understood that the request priority may be the priority of the data corresponding to the data request, and a higher request priority indicates that the data corresponding to the data request is more important; a priority flag corresponding to the data may be added to the data request.

In the specific implementation, when the master system receives the data request information, it analyzes each data request, determines the priority mark of each data request according to the analysis result, and sends the high priority data request to the slave system first according to the priority mark , and then send low-priority data requests to the slave system.

Further, in order to improve the request efficiency of important data, the determining the request priority of each data request in the data request information includes: determining the request data type corresponding to each data request in the data request information; The data type determines the request priority of each data request.

It can be understood that the requested data type can be the data type corresponding to the data request, and the requested data type includes sensor data, picture data, audio data, etc.; corresponding priorities can be set for each requested data type, and the requested data type has a higher priority. The corresponding request has high priority.

In specific implementation, for example, multiple types of data are stored in the virtual file system partition of the slave system, and the virtual file system partition is subdivided into different storage areas according to the data type, and different types of data are stored in corresponding areas; the main system When receiving the data request information, determine the requested data type corresponding to each data request in the data request information, and determine the priority of the corresponding data request according to the priority set for the requested data type in advance; the data with high real-time requirements can be set For high-priority data, set data with low real-time requirements as low-priority data, for example, set sensor data as high-priority data, and set image data as low-priority data.

In this embodiment, when the data request information is received, it is determined whether there is matching data in the local storage area; if not, the data request information is sent to the corresponding slave system, and the data storage area of the slave system is divided into A virtual file system partition storing data multiplexed by the external system; receiving matching data searched by the slave system from the virtual file system partition according to the data request information. In this embodiment, when there is no matching data corresponding to the data request information in the local storage area, the data request information is sent to the corresponding slave system, and the receiving slave system searches the virtual file system partition in the data storage area according to the data request information. Match data, so that multiple systems can access and operate the same storage area, realize the multiplexing of the same storage area by different systems, and solve the technology that some tasks cannot be executed due to the small storage space allocated to the system in smart devices Problem, while reducing hardware cost and hardware volume, it improves user experience.

Referring to FIG. 3 , FIG. 3 is a schematic flowchart of a second embodiment of the data management method of the present invention.

Based on the first embodiment above, in this embodiment, before the step S10, further includes:

Step S01: Determine the request frequency of the received data request.

It can be understood that the request frequency may be the frequency at which the same data request is received within a preset time period; the main system may count the number of received data requests, and calculate the request frequency of each data request according to the statistical results.

Step S02: When the request frequency is greater than the preset frequency, obtain matching data fed back from the system according to the data request through a preset data transmission channel in advance, and store the matching data in a local storage area.

It can be understood that the preset frequency may be a preset threshold frequency; if the request frequency is greater than the preset frequency, it is determined that the data request frequency corresponding to the data request is high. In order to improve the acquisition efficiency of the requested data, when the data request frequency is high, Obtain the matching data fed back by the slave system according to the data request through the preset data transmission channel in advance, and store the matching data in the local storage area. When the main system receives the data request, it can directly read the corresponding request data from the local storage area. There is no need to obtain request data from the slave system, which shortens the data transmission time, makes the data access path more efficient, and improves the acquisition efficiency of high-frequency request data. The preset data transmission channel can be established between the master system and the slave system for data transmission. The preset data transmission channel can be established based on UART, SPI, SHM or other methods, which is not limited in this embodiment.

It should be understood that when the request frequency is greater than the preset frequency, obtaining the matching data fed back from the system according to the data request through the preset data transmission channel in advance may be to determine that the corresponding data is a high-frequency request when the request frequency is greater than the preset frequency Data, the main system obtains the matching data fed back from the system through the preset data transmission channel in advance.

In a specific implementation, the main system obtains the number of data requests received, determines the request frequency of data requests according to the number of data requests, and when the request frequency is greater than the preset frequency, it determines that the corresponding data is high-frequency request data, and the main system advances Obtain the matching data fed back by the slave system according to the data request through the preset data transmission channel, and store the matching data in the local storage area. When the main system receives the data request corresponding to the high-frequency request data again, it can directly obtain the matching data from the local storage area. data.

Furthermore, for some high-frequency request data, if it is obtained from the slave system every time, the long access path will lead to low data acquisition efficiency. In order to reduce the access path of high-frequency request data and improve data acquisition efficiency, the The local storage area includes a local file system and a local cache; the step S02 includes: when the request frequency is greater than the first preset frequency, obtaining the matching feedback from the system according to the data request through a preset data transmission channel in advance data, and store the matching data in the local cache; and when the request frequency is greater than a second preset frequency, transfer the matching data from the local cache to the local file system, the The second preset frequency is greater than the first preset frequency.

In a specific implementation, the main system determines the request frequency of the data request, and when the request frequency is greater than the first preset frequency, the matching data fed back from the slave system according to the data request is obtained in advance through the preset data transmission channel, and the matching data is stored locally Cache, when the request frequency is greater than the second preset frequency, transfer the matching data in the local cache to the local file system.

Further, the matching data may be stored in the local file system or local cache. In order to reduce the data access path, when receiving the data request information, determining whether there is matching data in the local storage area includes: when receiving the data request information , judging whether there is matching data in the local file system; if not, judging whether there is matching data in the local cache; when the matching data does not exist in the local cache, judging that there is no matching data in the local storage area.

It should be noted that the virtual file system in the main system includes a file system adaptation module, a data communication module, a priority management module, and a cache management module. The file system adaptation module receives data request information and determines the Whether the matching data is stored in the local file system, if not, continue to judge whether the matching data exists in the local cache, if there is no matching data in the local cache, the priority management module identifies the request priority of each data request, the request priority After confirmation, the data communication module sends the data request to the slave system in order from high to low according to the priority of the request, and obtains the matching data found by the slave system according to the data request. During the operation of the system, the cache management module monitors each data in real time The request frequency of the request, and when the request frequency is greater than the first preset frequency, the corresponding matching data is obtained from the system in advance through the preset data transmission channel in advance, and the obtained matching data is first stored in the local cache. When the request frequency is greater than the second preset frequency, the matching data in the local cache is transferred to the local file system.

In the specific implementation, with reference to Fig. 4, Fig. 4 is a schematic flow chart of obtaining matching data from the system, when the master system receives the data request information, it judges whether the local file system stores matching data corresponding to the data request in the data request information, If it exists, read the matching data from the local file system; if it does not exist, judge whether the local cache stores the matching data corresponding to the data request, if it exists, read the matching data from the local cache; if not, determine The request priority of each data request in the data request information, according to the request priority, the data request is sent to the slave system. After receiving the data request, the slave system searches for matching data in the virtual file system partition according to the data request, and the slave system identifies the matching data. The data priority of the data, according to the data priority, the matching data is sent to the main system through the preset data transmission channel.

In this embodiment, the request frequency of the received data request is determined; when the request frequency is greater than the preset frequency, the matching data fed back from the system according to the data request is obtained in advance through the preset data transmission channel, and the matching data is Save to local storage area. In this embodiment, when the request frequency of the data request is greater than the preset frequency, the matching data is requested from the slave system in advance, and the matching data is stored in the local storage area, so that when the master system receives the data request again, it can directly download the matching data from the local storage area. Reading matching data reduces the data access path and improves the acquisition efficiency of high-frequency request data.
