Detailed Description
The present application will be described in further detail with reference to the drawings and examples. It is to be understood that the specific embodiments described herein are merely illustrative of the application and are not limiting of the application. It should be further noted that, for the convenience of description, only some of the structures related to the present application are shown in the drawings, not all of the structures.
Before discussing exemplary embodiments in more detail, it should be noted that some exemplary embodiments are described as processes or methods depicted as flowcharts. Although a flowchart may describe the steps as a sequential process, many of the steps can be performed in parallel, concurrently or simultaneously. In addition, the order of the steps may be rearranged. The process may be terminated when its operations are completed, but could have additional steps not included in the figure. The processes may correspond to methods, functions, procedures, subroutines, subprograms, and the like.
Example one
Fig. 1 is a flowchart of a method for dynamically allocating storage resources according to an embodiment of the present application, where this embodiment is applicable to a case where storage resources are dynamically allocated to shooting devices with different code rates, and the method may be executed by an apparatus for dynamically allocating storage resources provided in this embodiment of the present application, where the apparatus may be implemented in a software and/or hardware manner, and may be integrated in a device such as an intelligent terminal for allocating storage resources.
As shown in fig. 1, the method for dynamically allocating storage resources includes:
s110, determining a target code rate value of the shooting equipment; wherein the target code rate value comprises a code rate configuration value and a code rate calculation value; the code rate calculation value is determined according to historical code rate data;
in the present embodiment, the photographing apparatus may include a camera, a web camera, an analog camera, and the like. Preferably, the photographing apparatus may be IPC (IP Camera).
The code rate may refer to the number of data bits transmitted per unit time during data transmission. The code rate configuration value is determined according to the structure of the shooting equipment, and the code rate configuration value of each shooting equipment can be obtained from the bottom-layer storage information. The code rate calculation value can be obtained by calculation according to historical code rate data stored at the bottom layer.
In the scheme, when the system is initialized, the target code rate value of the shooting device is determined to only contain the code rate configuration value. After the shooting equipment works for a period of time, code rate calculation values can be obtained through real-time collection of code rate data of the shooting equipment in the period of time and calculation based on the code rate data.
And S120, distributing at least one resource block for the shooting equipment from the resource blocks of the pre-divided storage resources according to the target code rate value.
In this scheme, the entire storage resource may be divided into a number of resource blocks of the same size. For example 64MB or 32MB.
In this embodiment, when the upper system applies for the storage resource, the system allocates a plurality of continuous resource blocks to the shooting device according to the size of the target code rate value, and may virtualize the resource blocks into one logic block, that is, one logic block includes a plurality of resource blocks allocated to the same shooting device. The larger the target code rate value is, the larger the number of resource blocks to be allocated is.
After the resource blocks are distributed to the shooting equipment, the storage state of the system is monitored, if the situation that the shooting equipment has a flow break is monitored, and if the flow break time does not exceed a preset threshold value, the storage state can be ignored; and if the current interruption time exceeds a preset threshold value, canceling the group of data.
In the scheme, alarm plan setting can be carried out according to the image data stored in the resource block. If 24 groups of data in 24 hours are too little, the 24-hour data can be converted into 7-day data for alarm plan setting. The alarm data will typically have a periodic pattern on a daily basis. The alarm plan may refer to analyzing and processing stored data.
In this technical solution, optionally, allocating at least one resource block to the shooting device from resource blocks of pre-divided storage resources according to the target code rate value includes:
determining a minimum code rate configuration value from the code rate configuration values of all shooting devices, and taking the minimum code rate configuration value as a reference value;
and determining the proportional relation between the target code rate value and a reference value, and allocating at least one resource block for the shooting equipment from resource blocks of pre-divided storage resources based on the proportional relation.
In this embodiment, if there are multiple shooting devices during system initialization, the code rate configuration values of the shooting devices are obtained from the bottom layer, and at the allocation time, the minimum code rate configuration value is determined based on the code rate configuration values of the shooting devices. And carrying out quotient calculation on the target code rate value and the reference value to obtain a proportional relation between the target code rate value and the reference value, and allocating at least one resource block to the shooting equipment based on the proportional relation. For example, the proportional relationship between the target code rate value and the reference value is N, and if the resource block applied by the shooting device with the minimum code rate configuration value is 1 resource block, N resource blocks may be allocated to the shooting device based on the proportional relationship; if the resource block applied by the shooting device with the smallest code rate configuration value is 2 resource blocks, 2N resource blocks can be allocated to the shooting device based on the proportional relationship.
In this scheme, if only one shooting device exists during system initialization, a resource block may be allocated to the shooting device according to a preset allocation rule. For example, the N value may be calculated per 1GB size resource block.
The storage resources are allocated to the shooting equipment according to the target code rate value, and the image data of the multiple shooting equipment can be stored and concentrated in a small part of range of the storage resources, so that the method is favorable for the situation that the bottom layer resources are mechanical hard disks, avoids the swing of the magnetic head in a large range, and further improves the storage performance. On the other hand, for shooting equipment with a part of large code rates, the managed logic block is large, the continuity is good during reading, the number of management nodes is reduced, and the management efficiency of the system is improved.
In this technical solution, optionally, allocating at least one resource block to the shooting device from resource blocks of pre-divided storage resources according to the target code rate value includes:
under the condition that the resource blocks are allocated for the first time, allocating at least one resource block for the shooting equipment from the resource blocks of the pre-divided storage resources based on the code rate configuration value;
and under the condition that the resource blocks are not allocated for the first time, allocating at least one resource block for the shooting equipment from the resource blocks of the pre-divided storage resources based on the code rate calculation value.
In this embodiment, when the system is initialized, only the code rate configuration value of the shooting device may be obtained, and at least one resource block is allocated to the shooting device from the resource blocks of the pre-divided storage resources based on the proportional relationship between the code rate configuration value and the reference value. And in the working process of the shooting equipment, the code rate value can dynamically change along with the operation, and at least one resource block is allocated to the shooting equipment from the pre-divided resource blocks of the storage resources on the basis of the comparison relation between the code rate calculation value and the reference value.
In the scheme, if the system is restarted, the code rate calculation value is compared with the current configuration value of the shooting equipment, and if the deviation of the two values is greater than the preset threshold value, at least one resource block is allocated to the shooting equipment from the resource blocks of the pre-divided storage resources again based on the current configuration value. The preset threshold value can be set according to the resource block allocation requirement. For example, the threshold may be set to 20%, that is, after the system is restarted, if the deviation between the code rate calculation value and the current configuration value of the shooting device exceeds 20%, the resource block is allocated again based on the current configuration value.
The resource blocks applied by the shooting equipment are dynamically allocated, so that the management efficiency of the system can be improved.

The preset time period can be set according to the dynamic allocation requirement of the storage resources. For example, the time period may be set to 12 hours or 24 hours or the like. Preferably, the time period may be set to 24 hours. If the shooting device is not arranged in the all-day plan, the weight can be taken according to the ratio of the storage time to the 24 hours, so that the influence of the non-all-day calculation on the allocation of the resource blocks is reduced.
In this embodiment, the preset change time period may be determined according to a change point with large code rate fluctuation, and the time from the change point to the current time is referred to as the change time period.
According to the scheme, historical code rate data in a preset time period can be collected in real time, and the historical code rate data are averaged to obtain a code rate average value. Or collecting effective number of code rate data in a preset time period, and calculating to obtain a code rate average value based on the code rate data. For example, the code rate average value may be calculated based on the code rate data of 24 hours, or may be calculated based on the code rate data of the effective number within 24 hours.
In this embodiment, when the code rate value changes greatly during the operation of the shooting device, a code rate change point may be determined, and a code rate change value is calculated based on code rate data after the change point.
By dynamically allocating the resource blocks of the shooting equipment, the accuracy of resource block allocation can be improved, and the management efficiency of the system can be improved.
In this technical solution, optionally, allocating at least one resource block to the shooting device from resource blocks of pre-divided storage resources based on the code rate calculation value includes:
acquiring a current code rate value of the shooting equipment;
if the current code rate value meets the code rate fluctuation constraint condition, allocating at least one resource block for the shooting equipment from the resource blocks of the pre-divided storage resources based on the code rate average value;
and if the current code rate value does not meet the code rate fluctuation constraint condition, allocating at least one resource block for the shooting equipment from the pre-divided resource blocks of the storage resources based on the code rate change value.
The code rate waveform constraint condition may refer to a threshold value set according to code rate fluctuation of the shooting device. For example, the code rate waveform constraint can be set to be 5% of the average value of the code rates.
In this embodiment, the current code rate value of the shooting device may be collected in real time, whether the current code rate value exceeds a threshold value compared with the code rate fluctuation in the previous preset time period is judged, and if not, at least one resource block is allocated to the shooting device from the pre-divided resource blocks of the storage resource based on the proportional relationship between the code rate average value and the reference value. And if the code rate change value exceeds the reference value, allocating at least one resource block for the shooting equipment from the resource blocks of the pre-divided storage resources based on the proportional relation between the code rate change value and the reference value. Illustratively, the preset time period is set to be 24 hours, the threshold value is 5%, and if the current code rate value is not more than 5% of the code rate fluctuation in the previous 24 hours, the code rate average value in the 24 hours is taken to calculate the proportional relation; if the current code rate value is more than 5% of the code rate fluctuation in the previous 24 hours, determining a change point in the 24 groups of data, taking the average value after the change point as the code rate change value of the shooting equipment, and calculating a proportional relation based on the code rate change value.
By dynamically adjusting the allocation of the resource blocks, the management efficiency of the system can be improved.
According to the technical scheme provided by the embodiment of the application, the target code rate value of the shooting equipment is determined; and allocating at least one resource block for the shooting device from the resource blocks of the pre-divided storage resources according to the target code rate value. By executing the technical scheme, the image data of a plurality of shooting devices can be stored and concentrated in a small part of range of storage resources, which is more beneficial to the condition that the bottom layer resources are mechanical hard disks, the magnetic head is prevented from swinging in a large range, and the storage performance is further improved. On the other hand, for shooting equipment with a part of large code rates, the managed logic block is large, the continuity is good during reading, the number of management nodes is reduced, and the management efficiency of the system is improved.
Example two
Fig. 2 is a schematic diagram of a process of dynamically allocating storage resources according to a second embodiment of the present application, where the second embodiment is further optimized based on the first embodiment. The specific optimization is as follows: allocating at least one resource block for the photographing apparatus from resource blocks of pre-divided storage resources, including: creating a resource block index for at least one resource block of the shooting equipment; the resource block index comprises shooting equipment identification information, a starting resource block serial number, the number of resource blocks, image data storage starting time, image data storage ending time and a storage serial number; the storage sequence number is used for representing the storage sequence of the image data. The details which are not described in detail in this embodiment are shown in the first embodiment. As shown in fig. 2, the method comprises the steps of:
s210, determining a target code rate value of the shooting equipment; the target code rate value comprises a code rate configuration value and a code rate calculation value; the code rate calculation value is determined according to historical code rate data;
s220, distributing at least one resource block for the shooting equipment from pre-divided resource blocks of storage resources according to the target code rate value, and creating a resource block index for the at least one resource block of the shooting equipment; the resource block index comprises shooting equipment identification information, a starting resource block serial number, the number of resource blocks, image data storage starting time, image data storage ending time and a storage serial number; and the storage sequence number is used for representing the sequence of image data storage.
The resource block index is used for recording the summary information after the resource block is used. If the shooting equipment allocates a plurality of resource blocks, 1 logic block is created for the plurality of resource blocks, and the summary information of the logic block is recorded by using one index. If the shooting device allocates one resource block, 1 logic block is created for the resource block, and summary information of the logic block is also recorded by one index.
Exemplarily, fig. 3 is an index schematic diagram provided in the second embodiment of the present application, and as shown in fig. 3, the resource block index includes shooting device identification information, a starting resource block number, a number of resource blocks, image data storage start time, image data storage end time, and a storage number; the storage sequence number is used for representing the storage sequence of the image data.
In the scheme, the storage resource is divided into a plurality of resource blocks with the same size, and the first resource block is used for storing the summary information of the storage resource. Including the total capacity of the storage resources, the number of blocks, the version control information of the storage system, and the resource block index. When the system is initialized, if the first resource block is not enough to store the index information, the second resource block is used for storing the storage index in a sequential manner.
For example, fig. 4 is a schematic diagram of dividing storage resources according to a second embodiment of the present application, as shown in fig. 4, the storage resources are divided into a plurality of resource blocks with the same size according to 64MB, and finally, a part of the tail portion of the hard disk, which is less than 64MB, is discarded and not used. The sequence numbers 1-N are used to indicate resource blocks.
Exemplarily, fig. 5 is a schematic diagram of a super block and an index position provided in the second embodiment of the present application, as shown in fig. 5, a 1 st (serial number is 0) 64MB block stores the super block and a resource block index, and 12KB is reserved between the super block and the resource block index, so as to be used by a subsequent super block expansion; the unused portion of 64MB continues to be reserved. The super block is a first block of the file system, stores the structural information of the file system itself to describe a data structure of the whole information of the file system, mainly describes a directory of the file system and a static distribution condition of files, and describes the size, the number and the like of various constituent structures of the file system.
For example, fig. 6 is a schematic view of a super-block structure provided in the second embodiment of the present application, and as shown in fig. 6, the super-block design includes a magic word commonly used in a file system, a version number, a check of a data area, a capacity size of an entire storage resource, a block number, a UUID (universal Unique Identifier), and the like, and an index area size, an index area start position, a data area start position, and the like used in conjunction with the scheme.
In this technical solution, optionally, the method further includes:
and if the idle space of the resource block of the storage resource is used up, deleting the resource block corresponding to the at least one shooting device according to a preset rule based on the size of the storage resource.
In the scheme, after the space of the storage resource is allocated (the storage can be continued for a period of time), the image coverage logic is triggered, 1% -5% of the resource blocks of the whole storage resource are deleted in advance, and preparation is made for the application of the subsequent image storage space. When the resource block is deleted, all the resource blocks in the logic block corresponding to the resource block are deleted synchronously in order to avoid modifying the management structure. When the storage resource space is small, a minimum deletable value can be specified, and the situation that no enough space is available for reintegration after deletion is avoided; when the storage resource space is large, a maximum deletable value can be specified, so that excessive images can be prevented from being deleted once. After deletion, if the last application of the storage resource is insufficient, the deletion action can be triggered in advance.
In this embodiment, when a small quota is set for a small number of shooting devices, in order to keep the storage locations concentrated in a small range, after the storage of these shooting devices reaches the quota, new image data of these shooting devices may be stored in a new storage resource space, and old image data may be marked for deletion. When the image data is covered to the position, the image data can be directly recycled. When the quota set for the shooting devices is large and reaches the total storage resource amount, such as more than 50%, the shooting devices with the over-quota are directly subjected to cyclic coverage storage on the used storage positions, and the phenomenon that excessive image data are pre-deleted for preparing a continuous space in advance is reduced.
By setting a deletion rule for the storage resource, the validity of image data storage can be ensured, and the condition of insufficient storage resource is avoided.
According to the technical scheme provided by the embodiment of the application, the target code rate value of the shooting equipment is determined; and allocating at least one resource block for the shooting device from the resource blocks of the pre-divided storage resources according to the target code rate value. A resource block index is created for at least one resource block of the photographing apparatus. By executing the technical scheme, the storage resource can be allocated to the shooting equipment according to the target code rate value, and the resource block index is established for at least one resource block allocated to the shooting equipment, so that the randomness of image data storage can be reduced, and the storage performance can be improved. And the management efficiency of the system is improved.
