Detailed Description
The present application is described in further detail below with reference to figures 1-8.
For convenience of describing the present embodiment, a description is given in the context of an integrated power management circuit in a solid state disk.
The solid state disk is generally composed of modules such as a main control chip, a flash memory array and a cache chip, power supplies of the modules are all provided by an integrated power management circuit, and because the voltage provided by a host to the integrated power management circuit is higher than the power voltage required by each module of the solid state disk, the solid state disk is generally realized by adopting a step-down DC-DC converter.
For the input of the integrated power management circuit, the requirements of different host types need to be met, and for this purpose, the mode of the input power is usually set to be configurable. VinA is a main power supply provided by a host for an integrated power management circuit, two voltage domains of 3.3V +/-10% and 5V +/-10% need to be supported, when VinA cannot provide enough current capacity for an output channel, a standby power supply VinB needs to be used, and the voltage range is 12V +/-10%. There are three configuration modes of the input power: only VinA is needed, and VinB is not needed; (2) VinA and VinB are required simultaneously; (3) VinB if present is required.
The embodiment of the application discloses a solid state disk power supply management method, as shown in fig. 1, comprising the following steps:
s101, acquiring power supply data;
s102, judging whether the power supply data meet a preset power supply standard or not;
s103, if the power supply data do not accord with the preset power supply standard, acquiring corresponding abnormal power supply data;
s104, judging the abnormal type of the abnormal power supply data;
s105, if the abnormal type is input abnormal, acquiring and analyzing corresponding input voltage amplitude data to generate a corresponding abnormal analysis result;
s106, if the abnormal type is output abnormal, acquiring and analyzing corresponding output power supply data to generate a corresponding abnormal analysis result;
and S107, matching the corresponding exception handling strategy to carry out security handling according to the exception analysis result.
The power supply data in steps S101 to S103 refer to data related to power supply of a main power supply and a standby power supply of the solid state disk, and the preset power supply standard refers to a power supply standard capable of meeting normal work of the solid state disk.
In practical application, because the solid state disk must use the FTL to convert the logical address and the physical address, if power supply data abnormality occurs under normal operation conditions of the solid state disk such as reading, writing, deleting, and the like, which causes power supply abnormality, the mapping table may be lost due to update failure, and thus the solid state disk cannot be identified by the system, and the solid state disk has respective corresponding preset power supply standards according to different types of the solid state disk during normal operation.
Meanwhile, in order to improve the read-write performance, an SDRAM is usually used as a cache, and if power supply abnormality occurs in the read-write process, such as abnormal power failure, data in the SDRAM may not be written into Nand Flash to cause data loss, or an updated mapping table may not be written into Nand Flash, where the Nand Flash is one of Flash memories.
In steps S104 to S106, the abnormal power supply data refers to data related to the power supply data of the solid state disk that does not meet the corresponding preset power supply standard, the input voltage amplitude data refers to voltage amplitude data generated by the system power supply voltage of the solid state disk, and the output power supply data refers to power supply data output to each functional module in the solid state disk.
In practical application, the integrated power management circuit involves two types of abnormal interrupts, one is used for responding to input abnormality, the other is used for responding to output abnormality, and the system performs corresponding processing according to different interrupt types.
If the input of the solid state disk is abnormal, acquiring input voltage amplitude data generated by a system power supply for analysis; and if the output abnormality occurs, acquiring corresponding output power supply data for analysis, and generating a corresponding abnormality analysis result after analyzing according to the actual abnormality type of the solid state disk.
The anomaly analysis result in step S107 is a corresponding analysis result of an anomaly occurring in the solid state disk, and the anomaly handling policy is a solution corresponding to a specific anomaly condition in the anomaly analysis result.
The solid state disk power supply management method provided by this embodiment determines whether power supply data of a solid state disk meets a corresponding preset power supply standard, further obtains abnormal power supply data that does not meet the preset power supply standard in the power supply data, immediately determines an abnormal type of the abnormal power supply data, if the abnormal type is input, obtains and analyzes voltage amplitude data corresponding to an input voltage, generates a corresponding abnormal analysis result, if the abnormal type is output, obtains and analyzes corresponding output power supply data, generates a corresponding abnormal analysis result, and finally matches corresponding abnormal processing strategies with various abnormal types of all the power supply data for safety processing.
In one implementation of this embodiment, as shown in fig. 2, if the type of the abnormality is an input abnormality, the step S105 of acquiring and analyzing corresponding input voltage amplitude data and generating a corresponding abnormality analysis result includes the following steps:
s201, acquiring a corresponding voltage amplitude value according to input voltage amplitude data;
s202, judging the abnormal type of the voltage amplitude value;
s203, if the abnormal type is power failure, acquiring and analyzing a corresponding data storage progress to generate a corresponding abnormal analysis result;
and S204, if the abnormal type is voltage overshoot, acquiring the current voltage amplitude and the duration of the current voltage amplitude, and generating a corresponding abnormal analysis result.
In practical application, the voltage amplitude value refers to upper and lower amplitude values of input voltage in input voltage amplitude data, power failure refers to abnormal power failure of a power supply of a solid state disk system, data storage progress refers to storage progress of related data in a solid state disk when power failure occurs, and voltage overshoot refers to the fact that the peak value of the input voltage exceeds a set voltage and can cause failure of circuit components.
For example, when a system power supply shakes greatly in the moment, the influence on the solid state disk is huge, the fact that the power supply of the system is powered off can be known through the voltage amplitude value, at the moment, data which are being read and stored in the solid state disk are obtained, the storage progress of the data is further obtained, and the storage progress is analyzed to generate a corresponding abnormal analysis result.
For another example, as can be seen from the voltage amplitude value, if the peak value of the input voltage at a certain time exceeds the set voltage 15V, the current voltage abnormal amplitude and the duration of the voltage abnormal amplitude are obtained, which are inversely proportional, and if the voltage abnormal amplitude is larger, the system will issue an interrupt command faster.
According to the solid state disk power supply management method provided by the embodiment, the corresponding abnormal type of power failure or voltage overshoot of the power supply is obtained and analyzed according to the voltage amplitude value, so that the analysis of the power supply safety of the solid state disk when the input abnormality occurs is promoted.
In one implementation manner of this embodiment, as shown in fig. 3, step S203, namely, if the type of the abnormality is power failure, acquiring and analyzing a corresponding data storage progress, and generating a corresponding abnormality analysis result includes the following steps:
s301, judging whether the data storage progress accords with a preset storage standard or not;
s302, if the cache progress does not accord with a preset storage standard, acquiring the current data to be stored;
s303, acquiring a corresponding storage energy consumption value according to the current data to be stored;
s304, judging whether the storage energy consumption value meets a preset energy supply standard or not;
and S305, if the stored energy consumption value does not accord with the preset energy supply standard, generating a corresponding energy consumption difference as an abnormal analysis result according to the stored energy consumption value and the preset energy supply standard.
In practical application, the preset storage standard refers to a storage standard of related data in an operation process of the solid state disk, the current data to be stored refers to data which is not stored yet when a cache progress does not meet the corresponding preset storage standard, the storage energy consumption value refers to electric energy which needs to be consumed for storing the current data to be stored, the preset energy supply standard refers to an electric energy standard which can be provided by a standby power supply of the solid state disk, and the energy consumption difference refers to an electric energy difference which is caused by the fact that the current standby power supply has insufficient electric energy to store the current data to be stored and further needs to be consumed.
It should be noted that after the solid state disk is abnormally powered down, all data in the SDRAM must be completely written into the Nand Flash, generally, the capacity of the SDRAM is set to one thousandth of the bare capacity of the solid state disk, for a small-capacity solid state disk, the data to be written into the Nand Flash in the SDRAM is less, and the data can be continuously written through the super capacitor or the tantalum capacitor.
For example, according to a preset storage standard, all data in the SDRAM must be completely written into Nand Flash, the corresponding storage progress is 100%, the current data storage progress is detected to be 80%, it can be shown that 20% of the current data to be stored is not written into Nand Flash, further, the corresponding storage energy consumption value is obtained according to the current data to be stored is 2 watts, the storage electric energy which can be provided at this time is 1.5 watts according to the preset functional standard, the corresponding energy consumption difference is obtained to be 0.5 watts, and 0.5 watts is used as an analysis result of the power failure abnormality.
For another example, when the current data storage progress is detected to be 100%, which may indicate that all data in the SDRAM must be completely written into Nand Flash, the current 100% storage progress is obtained and displayed.
For another example, the corresponding storage power consumption value obtained according to the current data to be stored is 2 watts, the storage power which can be provided at the moment can be obtained according to the preset functional standard is 3 watts, and the storage power value which can be provided in the solid state disk is obtained and displayed in real time.
According to the power supply management method for the solid state disk, when the solid state disk is powered off, the data storage progress of the solid state disk is analyzed so as to obtain data which are not stored, whether the storage energy consumption value meets the preset energy supply standard or not is further judged, and then the energy consumption difference of the current data to be stored which does not meet the preset energy supply standard is obtained and serves as an abnormal analysis result, so that the safety of the data to be stored in the solid state disk in the storage process is improved.
In one implementation manner of this embodiment, as shown in fig. 4, after the step S304, that is, after determining whether the buffer power consumption value meets the preset power supply standard, the method further includes the following steps:
s401, if the stored energy consumption value meets a preset energy supply standard, acquiring corresponding energy supply distribution data;
s402, judging whether the energy supply distribution data meet a preset working standard or not;
s403, if the energy supply distribution data do not accord with the preset working standard, acquiring corresponding abnormal energy supply distribution data;
and S404, generating distribution difference as an abnormal analysis result according to the preset working standard and the abnormal energy supply distribution data.
In practical application, the energy supply distribution data refers to power supply distribution data of a system power supply or a standby power supply to each functional module in the solid state disk, the preset working standard refers to a standard of electric energy required by each functional module in the solid state disk to work normally, the abnormal energy supply distribution data refers to related abnormal data that the power supply distribution of the system power supply or the standby power supply cannot normally provide electric energy for each functional module in the solid state disk, and the distribution difference refers to an electric energy difference that the functional modules cannot work normally.
It should be noted that, in order to store the cache data in the NAND flash memory in a write-back manner, an energy storage capacitor and a related charge-discharge circuit need to be additionally added, and whether the input power supply is abnormally powered down is monitored in real time to trigger the power-down protection circuit to discharge the power-down protection circuit to the solid state disk for storing the cache data.
After the power failure protection circuit is triggered to discharge, the solid state disk firmware stops communication between the solid state disk and the host, cache data are stored completely, the size of the cache data at different power failure time points is different, the time and the energy required for storing the cache data are different, and in order to ensure that the cache data can be completely written into the NAND flash memory to be stored when the cache data are full, related auxiliary functional modules in the solid state disk also need corresponding power supply, so that enough spare energy storage capacitors are required.
For example, according to energy supply distribution data, the standby power supply can provide 3 watts of electric energy for the main control chip and 4 watts of electric energy for the SDRAM, further preset working standards can be obtained, the main control chip needs 4 watts of electric energy for normal operation, the SDRAM needs 4 watts of electric energy for normal operation, therefore, the energy supply distribution data can be judged to be not accordant with the corresponding preset working standards, abnormal power supply distribution data of the main control chip are further obtained, and 1 watt of distribution difference is generated to serve as an abnormal analysis result.
For another example, according to the available energy supply distribution data, the standby power supply can provide 4 watts of electric energy for the main control chip and 4 watts of electric energy for the SDRAM, so that it can be determined that the energy supply distribution data meets the corresponding preset working standard, and the electric quantity of the standby power supply is further monitored in real time.
According to the solid state disk power supply management method provided by the embodiment, whether the energy supply distribution data meet the corresponding preset working standard or not is judged, so that the safety analysis on the operation of other functional modules in the solid state disk is improved.
In one implementation manner of this embodiment, as shown in fig. 5, after the step S301 that is to determine whether the data storage progress meets the preset storage standard, the following steps are further included:
s501, if the cache progress accords with the preset storage standard, acquiring the power supply state of the solid state disk;
s502, judging whether the solid state disk recovers power supply within a preset time standard;
s503, if the power supply is not recovered, continuing to wait until the power supply of the solid state disk is recovered;
and S504, if the power supply is recovered, reestablishing the connection between the solid state disk and the host.
In practical application, the power supply state refers to whether the solid state disk recovers power supply after power failure occurs, and the preset duration standard refers to a predefined duration for detecting whether the solid state disk recovers power supply after power failure occurs.
It should be noted that, when the data in the cache is only half or less, much energy is not consumed after the data is completely written into the NAND flash memory, the solid state disk has no data read-write operation after the data is stored, the consumption is reduced, and a long time is required for the energy storage capacitor to completely discharge.
Therefore, in order to solve the problem that the host recovers normal power supply before the energy storage capacitor is completely discharged, so that the disk can not be identified, the host needs to detect whether the power supply state of the host recovers to be normal or not after the cache data is written back and stored in the NAND flash memory, and if the host recovers to be normal, the host needs to actively and repeatedly handshake connection with the host.
For example, if the PC host recovers power supply, because the energy storage capacitor array is not completely discharged, the CPU module of the solid state disk is still in an on-state, and only no data is read and written, and at this time, the PC host has recovered to operate normally, so that the solid state disk needs to be connected with the PC host again to perform normal read and write operations on the solid state disk; however, when the energy storage capacitor array is triggered to discharge, the solid state disk is already actively disconnected from the signal connection with the PC host, so that the solid state disk needs to be restarted at this time, and then the solid state disk is re-connected with the PC host. And if the PC host power supply does not recover to be normal before the energy storage capacitor array completely discharges, the energy storage capacitor module continues to discharge until the PC host power supply recovers to be normal, and then the energy storage capacitor module is connected with the solid state disk.
According to the power supply management method for the solid state disk, whether power supply is recovered within the preset time standard after the solid state disk is powered off is judged, if the power supply is recovered, the solid state disk is restarted to recover the state of the solid state disk, and the solid state disk is further connected with the host, so that the efficiency of establishing connection between the solid state disk and the host is improved.
In one implementation of this embodiment, as shown in fig. 6, if the type of the abnormality is an output abnormality, the step S106 of acquiring and analyzing the corresponding output power data and generating the corresponding abnormality analysis result includes the following steps:
s601, acquiring corresponding output voltage according to the output power data;
s602, judging whether the output voltage meets a preset output voltage standard or not;
s603, if the output voltage does not accord with the preset output voltage standard, judging the output abnormal type of the output voltage;
