Description

Technical Field

[0001] This invention relates to the field of battery protection, and in particular to a hard disk protection method, apparatus, and computer-readable storage medium. Background Technology

[0002] With the rapid development of the Internet, the demand for server performance and storage capacity is constantly increasing. Hard drives are still the most important storage devices for servers, and a large amount of important data is stored on hard drives, so protecting hard drives is particularly important.

[0003] Hard drives are typically mounted on the motherboard. When a short circuit occurs on the motherboard in a server due to a capacitor failure or other reasons, a large current will be generated, which can damage the hard drive. Currently, efuse protection circuits are commonly used to protect hard drives. Specifically, an efuse protection circuit is placed at the power supply point of the hard drive. When a large current is generated, the efuse protection circuit will block the current from flowing to the hard drive, thus protecting it.

[0004] However, using the efuse protection circuit can only prevent the large current caused by a short circuit from damaging the hard drive. When a fire occurs due to a short circuit in the motherboard circuit inside the server, maintenance personnel may not be able to reach the scene in a short time. Moreover, the server is a closed device and cannot be extinguished by external fire-fighting equipment in a short time. In this case, the efuse protection circuit alone cannot protect the hard drive. Furthermore, the damage to the hard drive caused by the fire will be fatal, and the lost data will be very difficult to recover. Summary of the Invention

[0043] The core of this invention is to provide a hard drive protection method, device, and computer-readable storage medium. It includes a fire detection device, an ejection device, and a protective housing. The protective housing has a receiving cavity. When a fire occurs inside the server, the fire detection device sends an electrical signal containing the characteristic values ​​of the fire to a control module. Based on the electrical signal, the control module controls the ejection device to eject the hard drive into the receiving cavity. The protective housing is made of fire-resistant and heat-insulating material, thereby protecting the hard drive from damage during a fire inside the server.

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0045] Reference Figure 1 , Figure 1 This invention provides a flowchart of a hard disk protection method, which is applied to a control module 22 in a hard disk protection device. The hard disk protection device also includes: a fire detection device 21, an ejection device 23, and a protective housing 24. The protective housing 24 has a receiving cavity and a through hole. The method includes:

[0046] S11: The control module 22 acquires the electrical signal of the characteristic value of the fire generated by the fire detection device 21;

[0047] S12: Determine whether the electrical signal is greater than the first preset value. If so, proceed to step S13.

[0048] S13: Control the ejection device 23 to eject the hard drive on the motherboard through the through hole into the receiving cavity.

[0049] When a fire occurs due to a short circuit on the motherboard inside the server, maintenance personnel may be unable to reach the site quickly enough, and external fire suppression systems may be unavailable to extinguish the fire. The damage to the hard drive from the fire will be fatal, and the lost data will be difficult to recover. To avoid damage to the hard drive caused by fire, this invention provides a hard drive protection method. Based on a fire detection device 21 detecting whether a fire has occurred inside the server, in the event of a fire, a control module 22 uses an ejection device 23 to eject the hard drive from the motherboard into the receiving cavity of the protective casing 24.

[0050] It should be noted that the control module 22 is not specifically limited; it can be a BMC (Baseboard Management Controller), or a BMC and a CPLD (Complex Programmable Logic Device). The control module 22 can acquire the electrical signal generated by the fire detection device 21 at certain time intervals. The time interval can be set according to actual application and is not specifically limited. When the control module is a BMC, the BMC executes the above-mentioned steps S11, S12, and S13. When the control module is a BMC and a CPLD, the CPLD executes the above-mentioned steps S11 and S12. When the CPLD determines that the electrical signal is greater than the first preset value, it sends a command to the BMC. When the BMC receives the command sent by the CPLD, it executes step S13. The fire detection device 21 is not specifically limited; it can be a smoke sensor or a temperature sensor. 1. An electrical signal can be sent to the control module via an interface. The characteristic value used to characterize the occurrence of a fire is not specifically limited and can be temperature or the concentration of gases such as CO, NO, and H2 produced during a fire. The control module 22 determines the degree of the fire based on the received electrical signal. The first preset value is not specifically limited. The ejection device 23 is not specifically limited and can be a spring device or an electromagnetic ejection device. The protective shell 24 is made of high-temperature resistant heat-insulating material. The specific material of the protective shell 24 is not limited. The number of through holes on the protective shell 24 is not specifically limited and can be one or more. The through holes are set in the direction of hard disk ejection. The number of receiving cavities is not specifically limited.

[0051] The present invention provides a hard drive protection method, which sets up a high-temperature resistant and heat-insulating protective shell 24 and the protective shell 24 is provided with through holes. When a fire occurs inside the server, the control module 22 controls the ejection device 23 to eject the hard drive on the motherboard into the receiving cavity through the through holes. Since the protective shell 24 is made of high-temperature resistant and heat-insulating material, it can effectively protect the hard drive when a fire occurs inside the server and avoid damage to the hard drive.

[0052] Based on the above embodiments:

[0053] In a preferred embodiment, S11: The control module 22 acquires the electrical signal of the characteristic values ​​of the fire generated by the fire detection device 21, including:

[0054] The control module 22 acquires the electrical signal of the gas concentration value generated by the fire collected by the fire detection device 21.

[0055] Specifically, the fire detection device 21 can be a temperature sensor or a smoke sensor. Considering that temperature sensors are greatly affected by the temperature of the external environment, as a preferred embodiment, a smoke sensor is selected for the fire detection device 21 in this embodiment. The specific type of smoke sensor is not specifically limited; it can be a gas-sensitive smoke sensor, such as a semiconductor gas sensor, a contact combustion gas sensor, or an electrochemical gas sensor. The smoke sensor converts the type of gas and its concentration-related information into electrical signals. Based on the strength of these electrical signals, information related to the presence of the gas to be tested in the environment can be obtained, thereby enabling detection, monitoring, and alarm functions to improve fire detection. Considering economy and applicability, a semiconductor gas sensor is usually selected. The gas to be tested using a semiconductor gas sensor is not specifically limited; the gas to be tested is the gas produced during a fire, such as CO or H2. The semiconductor gas sensor detects the concentration value of the gas to be tested by utilizing the change in physical properties such as conductivity when the gas to be tested comes into contact with the surface of a semiconductor (mainly metal oxide). This embodiment helps improve the accuracy of fire detection and enhances the protection effect on the hard drive.

[0056] In one preferred embodiment, the ejection device 23 includes: a controller and an ejection module;

[0057] S13: Controlling the ejection device 23 to eject the hard drive on the motherboard through the through hole into the receiving cavity, including:

[0058] Send an eject command to the controller so that when the controller receives the eject command, it controls the eject module to eject the hard drive on the motherboard through the through hole into the receiving cavity.

[0059] Specifically, in this embodiment, the internal structure of the ejection device 23 can be divided into a controller and an ejection module. No specific limitations are made regarding the controller and ejection module; for details, please refer to [reference needed]. Figure 7 , Figure 7 This is a schematic diagram of the ejection device 23 provided by the present invention. The ejection module can be further divided into a connecting mechanism and an ejection mechanism. The connecting mechanism is connected to the controller and the ejection mechanism respectively. The ejection mechanism is connected to the hard drive on the motherboard. When the controller receives the ejection command sent by the control module 22, it controls the ejection mechanism through the connecting mechanism to eject the hard drive on the motherboard into the receiving cavity. It should be noted that the ejection mechanism is not specifically limited and can be a spring or an electromagnetic ejection device, etc. This embodiment is simple to operate and easy to implement.

[0060] In one preferred embodiment, the protective housing 24 is provided with through holes that correspond one-to-one with the positions of the hard drives on the motherboard;

[0061] S13: Controlling the ejection device 23 to eject the hard drive on the motherboard through the through hole into the receiving cavity, including:

[0062] The ejection device 23 ejects the hard drive on the motherboard into the receiving cavity through its corresponding through hole.

[0063] Specifically, considering that in practical applications, the server motherboard has multiple hard drives, and if the number of through holes on the protective housing 24 is less than the number of hard drives, the through holes may become blocked, preventing subsequent hard drives from being ejected into the receiving cavity. Additionally, a fire could cause a rapid increase in temperature, damaging the hard drives that subsequently enter the receiving cavity. Therefore, in this embodiment, the protective housing 24 is provided with through holes that correspond one-to-one with the positions of the hard drives on the motherboard. These through holes are positioned in the hard drive ejection direction. (See reference...) Figure 5 This invention provides a schematic diagram of a protective housing structure. The top black part in the diagram is the protective housing, the bottom part is the motherboard, the middle rectangle is the hard drive, and the white part above is the through hole. When the control module controls the ejection device to eject the hard drive into the receiving cavity, the ejection device can eject the connected hard drives simultaneously, so that each hard drive is ejected into the receiving cavity through the corresponding through hole. This saves time and avoids the possibility that later hard drives may not be able to enter the receiving cavity due to insufficient through holes, or that later hard drives may be damaged due to rapid temperature rise caused by a fire. This effectively improves the protection of each hard drive.

[0064] In one preferred embodiment, the hard disk protection device further includes: a protection compartment controller; the protection housing 24 also includes a door drive module and a door;

[0065] S13: After the ejection device 23 ejects the hard drive on the motherboard through the through hole into the receiving cavity, it also includes:

[0066] After the hard drive is ejected into the receiving cavity, the protective compartment controller controls the compartment door drive module to close the compartment door.

[0067] Specifically, considering that a fire could raise the ambient temperature, potentially allowing heat to penetrate through the through-holes and causing damage to the hard drive, this embodiment includes a protective chamber controller. The protective housing 24 also incorporates a door drive module and a door. After the hard drive enters the cavity, the protective chamber controller controls the door drive module to close the door. It should be noted that the door is made of a high-temperature resistant, heat-insulating material. The specific material of the door is not limited, nor are the implementation and number of drive modules limited. The specific implementation for detecting the hard drive's presence in the cavity is also not limited; sensors can be used for detection. Generally, the door drive module and the door are located inside the protective housing. The protective chamber controller is connected to the drive module. After receiving a signal indicating that the hard drive has entered the cavity, the protective chamber controller controls the drive module to close the door. The number of doors corresponds one-to-one with the number of cavities; there can be one or more doors. In this embodiment, the door design better protects the hard drive, expanding the scope of application of this invention.

[0068] As a preferred embodiment, S13: After the ejection device 23 ejects the hard drive on the motherboard through the through hole into the receiving cavity, the method further includes:

[0069] The control prompt module issues a fire alarm message.

[0070] Specifically, this implementation includes a notification module to alert users in the event of a fire. It should be noted that the notification module is not limited; it can be a voice module that broadcasts a message to alert users when a fire occurs inside the server, or it can be a warning ringtone that emits a specific ringtone to alert users when a fire occurs inside the server, thus preventing further losses and facilitating user convenience.

[0071] In one preferred embodiment, the hard disk protection device further includes an efuse protection circuit;

[0072] S12: Before determining whether the electrical signal is greater than the first preset value, the following steps are also included:

[0073] Determine whether the electrical signal is greater than a second preset value and less than a first preset value, wherein the second preset value is less than the first preset value;

[0074] If so, control the efuse protection circuit to cut off the current between the motherboard and the hard drive;

[0075] Otherwise, proceed to the step of determining whether the electrical signal is greater than the first preset value.

[0076] Specifically, this implementation also includes an efuse protection circuit to cut off the current reference between the circuit on the motherboard and the hard drive in the early stages of a fire, according to the control module's instructions. Figure 3 The efuse protection circuit is installed on the line connecting the motherboard and the hard drive. When a short circuit occurs on the motherboard due to capacitor failure or other reasons, generating a large current, the efuse protection circuit cuts off the current between the motherboard and the hard drive. Compared with fuses and PPTC devices, the efuse protection circuit in this embodiment can achieve a wider range of protection functions and a higher level of control. In addition to high-speed short-circuit protection, the efuse protection circuit also provides precise overvoltage clamping, adjustable overcurrent protection, and adjustable voltage and current slew rate control to minimize inrush current and thermal shutdown. The specific process of the hard drive protection method in this embodiment can be found in [reference needed]. Figure 6 , Figure 6 This is a flowchart illustrating another hard drive protection method provided by the present invention. In this embodiment, the control module consists of a BMC and a PCLD. When the received electrical signal is between a first preset value and a second preset value, the PCLD sends a relevant signal to the BMC. The BMC controls the efuse protection circuit to cut off the current between the motherboard and the hard drive based on the signal. When the PCLD determines that the received electrical signal is greater than the first preset value, it also sends a relevant signal to the BMC. The BMC issues an ejection command based on the signal to control the ejection device to eject the hard drive into the receiving cavity and close the door. This embodiment avoids damage to the hard drive caused by damage to the circuitry on the motherboard, effectively improving the protection range of the hard drive.

[0082] The CPLD is connected to the fire detection device 21 and the BMC respectively, and the BMC is connected to the ejection device 23.

[0083] Specifically, considering the circuitry and number of pins connected to the BMC, this example uses a connection between the BMC and the CPLD as the control module 22. The CPLD receives the electrical signal sent by the fire detection device 21 and determines whether to send an alarm message to the BMC based on the strength of the signal. The BMC then controls the ejection device 23 to eject the hard disk into the receiving cavity according to the alarm command. For the specific implementation process, please refer to [reference needed]. Figure 4 This facilitates the implementation and connection of the device.
