Fig. 1 is a flowchart illustrating a method for adjusting a code rate according to an embodiment of the present application. By way of example and not limitation, as shown in fig. 1, the method comprises:
s101: the method comprises the steps of obtaining a current temperature value of a hard disk, and determining a target hard disk temperature interval where the current temperature value is located based on a pre-stored hard disk temperature interval set.
For example, the current temperature value of the hard disk may be obtained by reading a temperature value of the hard disk through SMART (Self Monitoring Analysis And Reporting Technology) in the hard disk.
Specifically, the hard disk temperature interval set comprises at least one hard disk temperature interval, and the corresponding hard disk temperature interval is determined according to the current temperature value so as to obtain the target hard disk temperature interval.
S102: and determining the target code rate percentage corresponding to the target hard disk temperature interval based on the temperature-code rate percentage corresponding relation.
The code rate percentage is the percentage of the original code rate in the hard disk temperature interval and the code rate written into the hard disk. The code rate percentage shows that in the hard disk temperature interval, the actual rate of writing into the hard disk is changed, and is not equal to the theoretical rate of writing into the hard disk, and the code rate is changed along with the change and becomes a few percent of the original code rate.
S103: and adjusting the code rate written into the hard disk to a target code rate, wherein the code rate percentage corresponding to the target code rate is less than or equal to the target code rate percentage.
When the code rate percentage corresponding to the target code rate is smaller than or equal to the target code rate percentage, the data volume written into the hard disk can be adjusted to enable the data bandwidth written into the hard disk to be matched with the actual bandwidth written into the hard disk.
The method comprises the steps of obtaining a current temperature value of a hard disk, and determining a target hard disk temperature interval where the current temperature value is located based on a pre-stored hard disk temperature interval set; determining the target code rate percentage corresponding to the target hard disk temperature interval based on the temperature-code rate percentage corresponding relation; the code rate written into the hard disk is adjusted to the target code rate, the code rate percentage corresponding to the target code rate is smaller than or equal to the target code rate percentage, the code rate of the hard disk can be dynamically adjusted to adjust the data bandwidth written into the hard disk based on the code rate percentages of different hard disk temperature intervals, and data loss caused by large difference between the written data bandwidth and the actual bandwidth of the hard disk is avoided, so that the performance and reliability of the hard disk are guaranteed, and further the performance and reliability of equipment using the hard disk are guaranteed.
Fig. 2 is a flowchart illustrating a method for adjusting a code rate according to another embodiment of the present application. As an example and not by way of limitation, as shown in fig. 2, before obtaining the current temperature value of the hard disk, the method further includes:
s201: and calculating the theoretical rate of writing the external equipment into the hard disk aiming at each hard disk temperature interval.
Specifically, the theoretical bandwidth written into the hard disk by the external device is multiplied by the number of written paths to obtain a theoretical rate; the number of write paths is the number of external devices connected to the hard disk.
Illustratively, the external device is a 1080P camera, and the theoretical bandwidth of the corresponding write-in hard disk is 1.5 MB/s; and 15 1080P cameras connected with the hard disk, namely 15 writing paths, so that the theoretical rate is 1.5MB/s 15-22.5 MB/s.
S202: the actual rate at which the external device writes to the hard disk is measured.
For example, the actual speed of writing to the hard disk by the external device may be printed in real time by entering a hard disk write command into the hard disk, so as to measure the actual speed. Hard disk write command: srfs _ test _ tool _ v500 mixwrite/dev/sdam n; wherein, the smrfs _ test _ tool _ v500 is a compiled file of theoretical bandwidth written into the hard disk by external equipment, the mixwrite is a dual-stream write, and the sda is a current hard disk drive identifier; m represents a printing level, and the printing level is 0-4, wherein the larger the level is, the more printing is performed, and m is 0, 1, 2, 3, 4; n represents the number of write paths.
S203: and calculating the code rate percentage of the hard disk in the hard disk temperature interval according to the theoretical rate and the actual rate.
Specifically, the theoretical rate is divided by the actual rate to obtain the code rate percentage of the hard disk in the hard disk temperature interval.
For example, if the theoretical rate is 22.5MB/s and the actual rate is 20MB/s in a certain hard disk temperature interval, the code rate percentage is 20 MB/s/22.5 MB/s or 88%.
S204: and obtaining the corresponding relation of the temperature-code rate percentage according to the temperature interval of each hard disk and the corresponding code rate percentage.
For example, the pre-stored set of hard disk temperature intervals comprises [60 ℃, 65 ℃ (65 ℃, 70 ℃ (70 ℃, 75 ℃ (75 ℃, 80 ℃ (80 ℃, 87 ℃), and the code rate percentage of each hard disk temperature interval is shown in the following table:
temperature interval of hard disk Number of write paths Theoretical rate of speed Actual rate Percentage of code rate
60℃-65℃ 15 22.5MB/s 22.5MB/s 100％
65℃-70℃ 15 22.5MB/s 22.5MB/s 100％
70℃-75℃ 15 22.5MB/s 20MB/s 88％
75℃-80℃ 15 22.5MB/s 18MB/s 80％
80℃-87℃ 15 22.5MB/s 5MB/s 22％

and acquiring the temperature value of the hard disk based on a preset environment temperature interval set to obtain a hard disk temperature interval set corresponding to the environment temperature interval set.
For example, the environmental temperature is divided every 5 ℃ to obtain an environmental temperature interval set [40 ℃, 45 ℃ (45 ℃), (45 ℃, 50 ℃), (50 ℃, 55 ℃ (55 ℃, 60 ℃ (60 ℃, 65 ℃), and the temperature value of the hard disk is correspondingly obtained based on the environmental temperature interval to obtain a hard disk temperature interval corresponding to the environmental temperature interval, so as to obtain a corresponding hard disk temperature interval set, and the corresponding relationship is shown in the following table:
interval of ambient temperature Temperature interval of hard disk
40℃-45℃ 60℃-65℃
45℃-50℃ 65℃-70℃
50℃-55℃ 70℃-75℃
55℃-60℃ 75℃-80℃
60℃-65℃ 80℃-87℃
On the basis, the code rate percentage of each environment temperature interval is obtained, and is shown in the following table:
interval of ambient temperature Temperature interval of hard disk Number of write paths Theoretical rate of speed Actual rate Percentage of code rate
40℃-45℃ 60℃-65℃ 15 22.5MB/s 22.5MB/s 100％
