Detailed Description
In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the present invention will be briefly described below with reference to the accompanying drawings and the description of the embodiments or the prior art, and it is obvious that the following description of the structure of the drawings is only some embodiments of the present invention, and other drawings can be obtained according to these drawings without inventive effort to a person skilled in the art. It should be noted that the description of these examples is for aiding in understanding the present invention, but is not intended to limit the present invention.
In order to ensure the service life of a magnetic disk, the embodiment of the application provides a motion data storage method, a motion data storage system and a motion data storage medium.
The method for storing sports data provided in the embodiment of the present application may be applied to a server, and it may be understood that the execution body does not constitute a limitation of the embodiment of the present application.
The motion data storage method provided in the embodiment of the present application will be described in detail below.
As shown in fig. 1, the first aspect of the present embodiment provides a motion data storage method, which may include the following steps S101 to S104.
And S101, responding to data storage requests initiated by at least two terminal devices, and distributing at least two memory buffer queues which are the same as the terminal devices in number and correspond to the terminal devices one by one for the at least two terminal devices.
The memory buffer queue comprises at least two memory buffers. The terminal device may be, but is not limited to, a smart bracelet or a device for collecting user movement data. The movement data may include, but is not limited to, heart rate data, blood oxygen data, blood pressure data, movement speed data, movement distance data, and/or geographic location data.
In one or more embodiments, memory buffer queues are allocated to at least two terminal devices, and multiple memory buffer queues with the same size, which are the same as the number of the terminal devices and correspond to each other one by one, can be allocated to at least two terminal devices according to the number of devices corresponding to the at least two terminal devices. For example, if the number of devices corresponding to the at least two terminal devices is 10, 10 memory buffer queues corresponding to the 10 terminal devices one by one and having the same size may be allocated to the 10 terminal devices in the memory of the server.
In one or more embodiments, memory buffer queues are allocated to at least two terminal devices, and at least two memory buffer queues which are the same as the terminal devices in number and in one-to-one correspondence may be allocated to at least two terminal devices according to the data size of the historical upload data of the at least two terminal devices. The size of the memory buffer queue allocated to the terminal device can be determined according to the data size of the historical uploading data of the terminal device, and the larger the data size of the historical uploading data of the terminal device is, the larger the memory buffer in the memory buffer queue allocated to the terminal device is.
And S102, writing the motion data uploaded by each terminal device in at least two terminal devices into a corresponding memory buffer area queue.
Specifically, when the at least two terminal devices upload motion data, the server may first write the motion data uploaded by each terminal device in the at least two terminal devices into a first memory buffer zone in the corresponding memory buffer zone queue, and after the first memory buffer zone in the memory buffer zone queue is full of data, write data into a next memory buffer zone in the memory buffer zone queue until all the motion data uploaded by the terminal devices are written into the corresponding memory buffer zone queue.
When writing motion data into the memory buffer areas in at least two memory buffer area queues, if any memory buffer area in any memory buffer area queue of the at least two memory buffer area queues does not exist, the fact that the remaining available memory buffer area in any memory buffer area queue is insufficient is indicated, at this time, an empty memory buffer area can be allocated for any memory buffer area queue, so that after the memory buffer area in which data is currently being written is full, the empty memory buffer area can be used for continuously writing motion data, and it is ensured that motion data uploaded by all terminal devices can be written into the corresponding memory buffer area queue.
And S103, if any one of the at least two terminal devices finishes data uploading, adding identification information representing the writing sequence of the data to a memory buffer zone queue corresponding to any one terminal device.
In one or more embodiments, the identification information is added to the memory buffer queue corresponding to any terminal device, and the identification information representing the writing sequence of the data may be added to the memory buffer queue corresponding to any terminal device according to the writing sequence represented by the history identification information added to the memory buffer queue last time. The last writing sequence represented by the history identification information added to the memory buffer area queue is prior to the data writing sequence represented by the identification information added to the memory buffer area queue corresponding to any terminal equipment.
And S104, writing the data in the memory buffer area queue added with the identification information into the disk in sequence according to the data writing sequence represented by the identification information added in the memory buffer area queue.
When the data in the memory cache queue is written into the disk, the data in the memory cache queue added with the identification information can be written into the disk in sequence according to the data writing sequence represented by the identification information added in the memory cache queue. Namely, the data in the memory buffer area queue corresponding to the terminal equipment for finishing data uploading is written into the disk firstly, and then the data in the memory buffer area queue corresponding to the terminal equipment for finishing data uploading is written into the disk. When data is written into the disk, the motion data uploaded by the same terminal equipment can be written into the disk at one time instead of continuously writing scattered data into the disk, so that the seek times are reduced, the seek time is reduced, the service life of the disk is prevented from being reduced due to the increase of seek times and seek time, the integrity of the data written into the disk is ensured, the phenomenon that the storage positions of the motion data uploaded by the same terminal equipment are too scattered in the disk is avoided, and the motion data of a user is conveniently searched.
In the embodiment of the present application, the allocation of the memory buffer queues for at least two terminal devices mainly aims at the situation that the number of terminal devices uploading motion data at the same time is limited. When the number of the devices corresponding to the at least two terminal devices is smaller than a preset threshold, at least two memory buffer queues which are the same as the number of the terminal devices and correspond to the terminal devices one by one are allocated to the at least two terminal devices in response to the data storage requests initiated by the at least two terminal devices. The preset threshold value can be set according to actual conditions.
In practical situations, a large number of terminal devices may upload motion data to the server at the same time, and due to limited memory capacity at the server, if a memory buffer queue (one memory buffer queue includes a plurality of memory buffers) is allocated for each terminal device, a memory shortage may occur. Therefore, if the number of the devices corresponding to the at least two terminal devices is greater than or equal to the preset threshold, the memory buffer areas which are the same as the number of the terminal devices and are in one-to-one correspondence can be allocated to the at least two terminal devices in response to the data storage requests initiated by the at least two terminal devices. And then writing the motion data uploaded by each terminal device in the at least two terminal devices into the corresponding memory buffer area, if the residual storage space of any memory buffer area is lower than the preset storage space, allocating a new memory buffer area for the terminal device corresponding to any memory buffer, and simultaneously writing the data in the memory buffer of the allocated memory buffer area into a disk to release the memory space, thereby preventing the situation of insufficient memory space.
In summary, according to the method for storing motion data provided in the embodiments of the present application, at least two memory buffer queues, which are the same as the number of terminal devices and are in one-to-one correspondence with the number of terminal devices, are allocated to at least two terminal devices in response to data storage requests initiated by at least two terminal devices, where the memory buffer queues include at least two memory buffers; then, the motion data uploaded by each terminal device in at least two terminal devices is written into a corresponding memory buffer area queue; if any one of the at least two terminal devices finishes data uploading, adding identification information representing the writing sequence of the data to a memory buffer zone queue corresponding to any one of the at least two terminal devices; and finally, writing the data in the memory buffer area queue added with the identification information into the disk in sequence according to the data writing sequence represented by the identification information added in the memory buffer area queue. Therefore, when the motion data uploaded by a plurality of terminal devices are stored, the motion data uploaded by the same terminal device can be written into the magnetic disk at one time, the seek times are reduced, the seek time is reduced, the service life of the magnetic disk is prevented from being reduced due to the increase of the seek times and seek time, meanwhile, the integrity of the data written into the magnetic disk can be ensured, the phenomenon that the storage positions of the motion data uploaded by the same terminal device are too dispersed in the magnetic disk is avoided, the motion data of a user is conveniently searched, and the practical application and popularization are facilitated.
