Detailed Description
The core of the application is to provide a power supply system which can stably and reliably supply power to the storage device. Another core of the present application is to provide a memory device, which also has the above technical effects.
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
Referring to fig. 1, fig. 1 is a schematic diagram of a power supply system according to an embodiment of the present disclosure, and referring to fig. 1, the power supply system mainly includes:
a Power Supply module 10, i.e., a PSU (Power Supply Unit) module, a Backup Power Supply module 20, i.e., a BBU (Backup Battery Unit) module, a control module 30, a Power Supply circuit 40, and a monitoring circuit 50. The power module 10 and the backup power module 20 are both connected to a power supply circuit 40, and the power supply circuit 40 is further connected to the storage system to supply power to the storage system. The monitoring circuit 50 is respectively connected to the power module 10 and the control module 30, and is configured to monitor a power supply state of the power module 10 and output the power supply state of the power module 10 to the control module 30. For the circuit structure of the monitoring circuit 50, details are not repeated in this application, and reference may be made to the existing monitoring circuit 50 having the power supply state monitoring function.
In the case that the power supply of the power supply module 10 is normal, the power supply module 10 supplies power to the storage system through the power supply circuit 40, and the control module 30 does not enable the backup power supply. When the power supply of the power supply module 10 is abnormal, the control module 30 enables the backup power supply module 20 to operate the backup power supply module 20, and at this time, the backup power supply module 20 supplies power to the storage system through the power supply circuit 40.
In order to realize the seamless switching of the power supplies of the power module 10 and the backup power module 20, that is, the power supply without power supply does not occur when the power module 10 and the backup power module 20 are switched, on one hand, when the power module 10 supplies power abnormally, the power module 10 does not power off immediately, but power off after the first preset time of full-load power supply, for example, power off after 3ms of full load. On the other hand, the time from when the control module 30 enables the backup power module 20 to when the backup power module 20 outputs power is less than or equal to the first preset time, for example, the time from when the control module 30 enables the backup power module 20 to when the backup power module 20 outputs power is 2ms, so that the backup power module 20 has already started supplying power when the power module 10 is powered off.
In addition, on the basis of the above embodiments, as a specific implementation manner, the control module 30 is a CPLD (Complex Programmable Logic Device). The control module 30 is specifically configured to output the power supply state of the power module 10 to the storage system, and enable the backup power module 20 after receiving an enable signal sent by the storage system when the power module 10 is abnormally powered.
In this embodiment, after receiving the power supply state of the power module 10 sent by the monitoring circuit 50, the control module 30 further sends the power supply state of the power module 10 to the storage system. On the basis that the backup power module 20 is in place, after analyzing that the power supply of the power module 10 is abnormal, the storage system sends an enable signal to the control module 30, and then the control module 30 receives the enable signal and then enables the backup power module 20 to operate and discharge the backup power module 20.
In addition, on the basis of the above embodiment, referring to fig. 2, as a specific implementation, the power supply circuit 40 includes a TPS2474X combination chip.
Specifically, the backup power module 20 is provided with a backflow prevention circuit inside, and the backflow prevention circuit stored in the backup power module 20 and the power supply branch of the power module 10 inside the TPS24 2474X combined chip form an or gate. In addition, the TPS2474X combiner chip sets the Hotswap function. The voltage output to the storage system by the TPS2474X combiner chip gradually reaches the voltage value output by the power module 10 or the backup power module 20, thereby achieving power-on slow start and preventing inrush current.
Further, on the basis of the foregoing embodiment, as a specific implementation manner, the control module 30 is further configured to control the backup power module 20 to stop supplying power after receiving a control signal sent by the storage system after completing data backup.
Specifically, when the power module 10 supplies power abnormally, the storage system starts a data backup process for data backup, and the backup power module 20 mainly functions to supply power to the storage system during the data backup of the storage system, so that the storage system can perform data backup. After the storage system completes the data backup, the backup power module 20 may not need to continue discharging, so after the storage system completes the data backup, the storage system sends a control signal to the control module 30, and after the control module 30 receives the control signal, the control module controls the backup power module 20 to stop supplying power, and the storage system is powered off.
Further, on the basis of the foregoing embodiment, as a specific implementation manner, the control module 30 is further configured to receive a test enable signal periodically sent by the storage system, and after receiving the test enable signal, control the power module 10 and the backup power module 20 to alternately supply power according to a preset rule, so that the storage system detects whether the backup power link is normal.
Specifically, in this embodiment, the memory system is provided with a standby power self-diagnosis function. The storage system is periodically tested for a standby power function. For example, when the storage system is started or after the storage system continues to work for 3 months, the power-on function test is performed. When the storage system performs the standby power function test, it sends a test enable signal to the control module 30. After receiving the test enable signal, the control module 30 switches power supply according to a preset rule, so that the power supply module 10 and the backup power supply module 20 supply power alternately. And then detect whether the standby power link is normal in the process of alternately supplying power to the power module 10 and the standby power module 20. If the storage system has power failure in the process of alternately supplying power to the power module 10 and the backup power module 20, it is determined that the backup power link is abnormal.
For example, when performing a standby power function test, the control module 30 first switches to the standby power link, supplies power from the standby power module 20, and cuts off the power supply link after a delay time (less than the power-off duration of the power module 10). And switching back to the power supply link after 1 second, supplying power by the power module 10, and cutting off the standby power link after delaying for a period of time. In the process, if the storage system is powered down, the standby power link is judged to be abnormal. And conversely, if the power failure does not occur in the storage system, judging that the standby power link is normal. When the standby electric link is abnormal, the storage system further restores through resetting the original elements such as the MOS tube and alarms when the restoration is unsuccessful.
In summary, the power supply system provided by the present application is provided with two power supply devices, and when the power supply module supplies power normally, the power supply device supplies power by the power supply module, and once the power supply module supplies power abnormally, the power supply device can be switched to supply power by the backup power supply module. And when the power supply of the power supply module is abnormal, the power supply module cannot be powered off immediately, but is powered off after one end of full-load power supply. Before the power supply module is powered off, the backup power supply module supplies power normally, so that seamless switching of power supply between the power supply module and the backup power supply module is realized, and the stability and reliability of power supply are guaranteed.
The present application also provides a storage device that is described below and that can be referenced in correspondence with the power supply system described above. The storage device includes:
a power supply system and a storage system; the power supply system includes: the device comprises a power supply module, a backup power supply module, a control module, a power supply circuit and a monitoring circuit; the power supply module is used for supplying power to the storage system through the power supply circuit; the monitoring circuit is used for monitoring the power supply state of the power supply module and outputting the power supply state of the power supply module to the control module; the control module is used for enabling the backup power supply module when the power supply of the power supply module is abnormal, so that the backup power supply module supplies power to the storage system through the power supply circuit; when the power supply module supplies power abnormally, the power supply module is powered off after being fully loaded with power for a first preset time, and the time from the backup power module to the backup power module for outputting power is enabled by the control module to be less than or equal to the first preset time.
And carrying out self-checking after the storage system is started, and if the self-checking is normal, carrying out standby power link detection. And if the power-on self-test is abnormal, the power-off is carried out. If the standby power link is normal, a cluster is established and the storage system works normally. If the standby electric link is abnormal, the storage system enters an abnormal repair flow, for example, the relevant MOS transistor is reset, and an alarm is given when the repair is unsuccessful.
When the power supply of the power supply module in the power supply system is abnormal, the storage system starts a data backup process to perform data backup. In a specific embodiment, the storage system is specifically configured to start a data backup process to perform data backup when the power supply module supplies power abnormally and the power supply module does not return to normal power supply after a second preset time.
Specifically, the storage system is connected with the control module through a PCA9551 chip. The storage system monitors whether the backup power module is in place through an internal PCH (south bridge), that is, whether the backup power module is inserted. The storage System monitors the operating state of the backup power module through an SMBUS (System Management Bus). The method comprises the steps of sending a standby power condition enable to a control module according to the working state of a standby power module, namely sending an enable signal for switching power supply of the standby power module to the control module, sending an enable signal for detecting a standby power link to the control module after a 1-second power failure test enable, sending an enable signal for charging the standby power module to the control module after a charging enable, and the like.
When the power supply module supplies power abnormally, the control module switches the power supply and supplies power by the backup power supply module. If the power supply of the power supply module is recovered to be normal within a second preset time, such as 5 seconds, when the power supply of the power supply module is abnormal, the storage system does not enter a standby power flow. If the power supply of the power supply module is not recovered to be normal within 5 seconds, starting data backup, entering a standby power flow formally, and controlling the peripheral power supply equipment to power off by the storage system. And if the power supply process of the power supply module is recovered to be normal subsequently, restarting the storage system.
Further, on the basis of the foregoing embodiment, as a specific implementation manner, the storage system is further configured to start self-discharge of the backup power module, sample a discharge current of the backup power module in a self-discharge process of the backup power module, obtain a discharge power of the backup power module according to the discharge current, and perform an abnormal alarm when the discharge power of the backup power module does not meet a backup power requirement.
In this embodiment, the storage system further pre-determines the standby power capability of the backup power module, and performs an abnormal alarm when the standby power capability of the backup power module does not satisfy the standby power requirement, for example, does not satisfy the two standby power requirements. Specifically, the discharge power of the backup power module reflects the backup power capability of the backup power module. Therefore, the storage system first sends an enable signal for enabling the internal self-discharge of the backup power supply module to the control module, so that the control module controls the backup power supply module to perform the internal self-discharge. In the process of self-discharging in the backup power supply module, the storage system samples the discharging current of the backup power supply module, multiplies the voltage of the backup power supply module by the current obtained by sampling after integrating the current to obtain the discharging power of the backup power supply module, compares the obtained discharging power with a preset threshold value, and represents that the standby power capacity of the backup power supply module meets the standby power requirement if the obtained discharging power reaches the preset threshold value. On the contrary, the standby power requirement is not satisfied.
Further, on the basis of the above embodiment, as a specific implementation manner, the storage system is further configured to periodically trigger the backup power module to repair the battery chemical characteristic curve.
Specifically, in this embodiment, the storage system is further configured to periodically trigger the backup power module to perform battery chemical characteristic curve repair, so that the backup power module perfects a BBU sampling algorithm according to the battery chemical curve, and sampling accuracy is ensured. For example, the backup power module is triggered every three months to repair the battery chemical characteristic curve, so that the backup power module perfects the BBU sampling algorithm according to the battery chemical curve.
In summary, in the storage device provided by the present application, the power supply system includes two power supply apparatuses, and the power supply apparatus is powered by the power supply module when the power supply module is normally powered, and can be switched to be powered by the backup power supply module when the power supply module is abnormally powered. And when the power supply of the power supply module is abnormal, the power supply module cannot be powered off immediately, but is powered off after one end of full-load power supply. Before the power supply module is powered off, the backup power supply module supplies power normally, so that seamless switching of power supply between the power supply module and the backup power supply module is realized, and the stability and reliability of power supply are guaranteed.
