The present embodiment and the following embodiments are exemplified below by taking the master system as an example.
It is understood that the data request information may be information requesting to invoke data, the data request information includes data requests, and the number of the data requests in the data request information is at least one; the local storage area may be a storage area allocated to the host system when the hardware is designed; the matching data may be data stored in the local storage area and matching the data request in the data request information, for example, if the data request in the data request information is a gyroscope data request, the matching data is gyroscope data, where the data request may also be a picture data request, an audio data request, and the like, and this embodiment is not limited herein.
In a specific implementation, when the host system receives the data request information, the data request included in the data request information is determined, and whether data matched with the data request is stored in a local storage area allocated to the host system is judged.
Step S20: and if the data request information does not exist, the data request information is sent to a corresponding slave system, and a virtual file system partition for storing the multiplexing data of the external system is divided in a data storage area of the slave system.
It is understood that the master system and the slave system may be determined according to the role in accessing and operating the same storage area, the number of the slave systems is at least one, the master system may request data from the virtual file system partition in the slave system data storage area, for example, there are 3 systems a, B and C, it is assumed that system a requests data from the data storage area of system B, and at this time, data a may be called the master system, system B may be called the slave system, and it is assumed that system B requests data from the data storage area of system C, and at this time, data B may be called the master system, and data C may be called the slave system; the data storage area can be a storage area allocated to the slave system during hardware design; the external system multiplexing data can be data which can be used by both the master system and the slave system; the virtual file system partition can be a storage partition which is divided in the data storage system and used for storing the virtual file system; because the operating state of the system is constantly changing, in order to adapt to different operating states of the system, the size of the virtual file system partition can be dynamically adjusted according to the operating state of the system, for example, the data size of the request data in the preset historical time length is determined, and the size of the virtual file system partition is adjusted according to the data size.

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 back the searched data to the master system.
In a specific implementation, for example, the wearable device includes three systems, which are a system a, a system B, and a system C, where the system a is a master system, and the system B and the system C are slave systems of the system a, where a data storage area of the system B is divided into virtual file system partitions B1 for storing sensor data, a data storage area of the system C is divided into virtual file system partitions C1 for storing picture data, data request information received by the system a includes a picture data request and a sensor data request, the system a finds corresponding picture data and sensor data in a local storage area, sends the picture data request to the system C, sends the sensor data request to the system B, the system B finds sensor data in the virtual file system partition B1 after receiving the sensor data request, and feeds back the found sensor data to the system a, and the system C finds picture data in the virtual file system partition C1 after receiving the picture data request; the data is not limited to the picture data and the sensor data, and may also be audio data, video data, and the like, and the picture data and the sensor data may also be stored in the system B or the system C at the same time, and at this time, only the data needs to be requested from the system B or the system C, and the embodiment is not limited herein.
Further, in order to improve the request efficiency of important data, the sending the data request information to a corresponding slave system includes: determining the request priority of each data request in the data request information; and sequentially sending the data requests to corresponding slave systems according to the request priority.
It is understood that the request priority may be a priority of 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 for the corresponding data may be added to the data request.
In specific implementation, when the master system receives the data request information, the master system analyzes each data request, determines a priority mark of each data request according to an analysis result, sends the data request with high priority to the slave system according to the priority mark, and then sends the data request with low priority 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 a request data type corresponding to each data request in the data request information; and determining the request priority of each data request according to the request data type.

In specific implementation, for example, multiple types of data are stored in a virtual file system partition of a system, the virtual file system partition is subdivided into different storage areas according to the data types, and the different types of data are stored in the corresponding areas; when the main system receives the data request information, determining a request data type corresponding to each data request in the data request information, and determining the priority of the corresponding data request according to the priority preset for the request data type; data with high real-time requirements may be set as high priority data and data with low real-time requirements may be set as low priority data, e.g. sensor data may be set as high priority data and picture data may be set as low priority data.
