[0014] The present application solves the technical problem in the prior art that hard disk destruction requires high energy consumption by providing a hard disk soft destruction method with low power consumption.

[0015] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0016] It should be noted that the terms "including" and "having" are intended to cover non-exclusive inclusions. For example, a process, method, system, product or server that includes a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or modules that are not explicitly listed or are inherent to these processes, methods, products or devices.

[0017] Examples, such as Figure 1 As shown, the embodiment of the present application provides a hard disk soft destruction method under low power consumption, wherein the method comprises:

[0018] A high-level signal destruction circuit is obtained, wherein the high-level signal destruction circuit includes a destruction button, a large battery, a small battery, a hard disk, an MCU, an EC, a first electronic switch, and a second electronic switch.

[0019] High level signal destroys the circuit Figure 2 As shown, the high-level signal destruction circuit includes a destruction button, a large battery, a small battery, a hard disk, an MCU (micro control unit), an EC (embedded controller), a first electronic switch, and a second electronic switch. Among them, the destruction button is a manual button that triggers the hard disk destruction operation. When the user presses it, the destruction process will be started; the large battery is used to power the device in normal working state to ensure the operation of the system and the execution of the hard disk destruction operation; the small battery is a backup battery, which is used to provide power when the device is turned off or in a low-power state to ensure that the hard disk can be destroyed even in the turned-off state; the hard disk is the target device for storing data and the object of the destruction operation; the MCU is responsible for managing the logical operations in the destruction circuit, and controls the destruction process of the hard disk after receiving the destruction signal; the EC is responsible for power management and system status monitoring to ensure that the system can support the hard disk destruction operation in different working modes; the first electronic switch is responsible for opening and closing the large battery power supply channel, and the second electronic switch controls the small battery to power the hard disk destruction operation in the turned-off state.

[0020] A hard disk state destruction model is constructed according to the high-level signal destruction circuit, and the hard disk state destruction model includes a hard disk state recognition layer and a soft destruction strategy layer.

[0021] Based on the high-level signal destruction circuit, a hard disk state destruction model is constructed. The hard disk state destruction model includes two main layers: hard disk state recognition layer and soft destruction strategy layer. The hard disk state recognition layer is responsible for detecting the current working state of the hard disk and identifying whether the hard disk is in a destroyable state. Specifically, the hard disk state recognition layer determines whether the destruction operation can be performed by detecting whether the hard disk is in a power supply state and whether the device is in a power-on or power-off state; the soft destruction strategy layer outputs the corresponding destruction strategy based on the state analysis. When the hard disk state recognition layer confirms that the hard disk can be destroyed, the soft destruction strategy layer selects a suitable destruction strategy according to the current state of the hard disk (such as hard disk usage, power status, etc.). The destruction strategy includes deciding whether to use a large battery or a small battery for power supply, using a high-level signal or a low-level signal to trigger destruction, and selecting an appropriate destruction mode (for example, partial data destruction or complete data destruction). By combining hard disk state recognition with soft destruction strategy, the hard disk state destruction model can intelligently control the hard disk destruction operation when the system is in different states (powered on or off), thereby achieving flexibility in data destruction and optimization of power consumption.

[0022] Furthermore, if Figure 3 As shown, the construction of the hard disk state destruction model includes:

[0023] Acquire the device operation status, wherein the device operation status includes a normal working status and a shutdown status; perform state matching training on the device operation data set based on the device operation status to generate the hard disk state recognition layer; configure the destruction program for the device operation status based on the high-level signal destruction circuit to obtain the soft destruction strategy layer; connect the hard disk state recognition layer and the soft destruction strategy layer at the functional layer to construct the hard disk state destruction model.

[0024] Specifically, the operating status information of the device is collected through the device's sensors and log records, and the device operating status includes normal working status and shutdown status; based on the device's operating status, the device's operating data set is trained for state matching, that is, using various operating data under different device states to train a model that can identify the hard disk state, namely, the hard disk state recognition layer, so that the hard disk state recognition layer can accurately identify the current operating status of the device; based on the high-level signal destruction circuit, the corresponding destruction program is configured under different operating states of the device, so as to obtain the soft destruction strategy layer, and the soft destruction strategy layer formulates an appropriate destruction plan according to the operating status of the device, such as using a large battery to power the destruction under normal working status, and using a small battery to perform destruction under shutdown status; the hard disk state recognition layer is functionally connected with the soft destruction strategy layer to form a complete hard disk state destruction model.

[0025] Furthermore, obtaining the soft destruction strategy layer includes:

[0026] Based on the high-level signal destruction circuit, a destruction program analysis is performed on the normal working state to determine the soft destruction strategy of the device in the normal state; through the high-level signal destruction circuit, a destruction program analysis is performed on the shutdown state to determine the soft destruction strategy of the device in the shutdown state; based on the soft destruction strategy of the device in the normal state and the soft destruction strategy of the device in the shutdown state, strategy matching training is performed to obtain the soft destruction strategy layer.

[0027] Preferably, based on the high-level signal destruction circuit, the operating characteristics of the device when it is in a normal working state are analyzed, and by analyzing various types of data of the device in the normal working state, a soft destruction strategy suitable for the state is determined, and a soft destruction strategy for the normal state of the device is generated. For example, in the normal working state, the device is powered by a large battery, so the destruction operation can be performed through the normal power supply, ensuring the speed and efficiency of hard disk destruction; through the high-level signal destruction circuit, the operating characteristics of the device in the shutdown state are analyzed. In the shutdown state, the power consumption of the device is extremely low, and some circuits stop working, but the hard disk destruction operation can still be triggered by the backup small battery; the soft destruction strategy for the shutdown state of the device needs to consider the low power consumption requirements to ensure that the destruction program can still be safely executed in the shutdown state without consuming too much battery power, and finally, the soft destruction strategy for the shutdown state of the device is generated; based on the soft destruction strategy for the normal working state of the device and the soft destruction strategy for the shutdown state, the destruction schemes in the two states are trained for strategy matching, and the destruction strategies in the two states are matched and integrated using machine learning or rule engines and other technologies, and the model is trained to identify the device state and select an appropriate destruction strategy according to the state; after the training is completed, a soft destruction strategy layer is obtained.

[0028] Furthermore, the device normal state soft destruction strategy is specifically:

[0029] When in the normal working state, the hard disk and the EC are powered by the large battery, the first electronic switch and the second electronic switch are disconnected, and the small battery does not power the hard disk and the MCU; when the destroy button is triggered, a hard disk destroy signal is generated; the destroy signal is received by the EC detection and a high-level signal is output to the hard disk, and the hard disk starts the destruction function.

[0030] When the device is in normal working state, the large battery is responsible for powering the hard disk and EC (embedded controller) to ensure that the system maintains efficient operation under normal operating conditions; at this time, the first electronic switch and the second electronic switch are disconnected to ensure that the small battery does not supply power, that is, the small battery does not supply power to the hard disk and MCU (microcontroller unit) to save the energy of the small battery and ensure that it serves as a backup power supply when the device is turned off. When the user presses the destroy button, a hard disk destruction signal is generated, indicating that the hard disk destruction function needs to be activated; after receiving the destroy button signal, the EC will detect and confirm the signal, and then the EC will output a high-level signal to the hard disk to activate the hard disk destruction function. Through the above steps, the device can rely on the large battery for power supply under normal working conditions, and by triggering the destroy button, the high-level signal output by the EC is used to effectively activate the hard disk destruction function, ensuring that the destruction operation is carried out smoothly during the normal operation of the system.

[0031] Furthermore, the device shutdown state soft destruction strategy is specifically:

[0032] When in the shutdown state, the large battery does not power the hard disk and the EC, the first electronic switch and the second electronic switch are disconnected, and the small battery does not power the hard disk and the MCU; when the destroy button is triggered, the second electronic switch is turned on, and the MCU is powered by the small battery, and the MCU outputs a PEN signal and turns on the first electronic switch, and the small battery powers the hard disk; a high-level signal is output to the hard disk by the MCU, and the hard disk starts the destruction function.

[0033] When the device is in the shutdown state, the large battery does not power the hard disk and EC (embedded controller), and the device enters a low power consumption mode; at this time, the first electronic switch and the second electronic switch are both disconnected, and the small battery does not power the hard disk and MCU (microcontroller unit). When the user presses the destroy button, the hard disk destruction process is started; at this time, the second electronic switch is turned on, so that the small battery starts to power the MCU, and the MCU starts and enters the working state; after receiving the power supply from the small battery, the MCU outputs a PEN signal, and the PEN signal turns on the first electronic switch; after turning on the first electronic switch, the small battery starts to power the hard disk, ensuring that the hard disk can obtain enough power to perform the destruction operation in the shutdown state; after the power supply is stable, the MCU outputs a high-level signal to the hard disk; after the hard disk receives the signal, it starts the destruction function and executes the data destruction operation. Through this strategy, the device can still effectively use the small battery to realize the hard disk destruction operation in the shutdown state, while maintaining the low power consumption characteristics of the system, ensuring that the data is safely destroyed without affecting the device's battery life.

[0034] A destruction strategy analysis is performed on the target device based on the hard disk status destruction model, and a target hard disk destruction strategy is output.

[0035] The current operating status of the target device is analyzed through the constructed hard disk status destruction model. The hard disk status destruction model combines the hard disk status recognition layer and the soft destruction strategy layer, and can determine whether the device is in normal working state or shutdown state, and perform corresponding destruction strategy analysis based on these states. The operating status data of the current device is obtained through the hard disk status recognition layer, and the most appropriate destruction strategy is selected in combination with the power consumption and destruction requirements of the device. For example, if the device is in normal working state, it is selected to be destroyed through power supply of a large battery; if the device is in shutdown state, it is selected to be destroyed through power supply of a small battery. After fully analyzing the device status, the hard disk status destruction model will output the target hard disk destruction strategy that best suits the current operating status of the device, including the triggering conditions for destruction, the selection of the power supply path (large battery or small battery), the signal transmission path (through EC or MCU), and the specific destruction operation process.

[0036] The target device is subjected to hard disk soft destruction processing according to the target hard disk destruction policy.

[0037] The target device is softly destroyed according to the output target hard disk destruction strategy. If the device is in normal working condition, the hard disk and EC (embedded controller) are powered by a large battery; when the destroy button is triggered, the EC detects the destroy signal and outputs a high-level signal to the hard disk, and the hard disk immediately starts the destruction function and performs the soft destruction operation. If the device is in the off state, the MCU (microcontroller unit) is powered by a small battery; when the destroy button is triggered, the MCU starts with a small battery, outputs a PEN signal to turn on the first electronic switch, and then the small battery starts to power the hard disk, the MCU outputs a high-level signal to the hard disk, and the hard disk starts the destruction function.

[0038] Further, the method comprises:

[0039] After the hard disk is destroyed, a destruction status signal is output to the MCU, and the MCU outputs a PEN inverted signal to the first electronic switch, and the first electronic switch is disconnected to stop powering the hard disk; the MCU outputs a NEN signal to the second electronic switch, and the second electronic switch is disconnected, and the small battery turns off powering the MCU.

[0040] When the hard disk is destroyed, it will send a destruction status signal to the MCU (microcontroller unit) to inform the MCU that the destruction process of the hard disk has been successfully completed; after receiving the destruction status signal of the hard disk, the MCU will generate a PEN inversion signal and send it to the first electronic switch; after receiving the inversion signal, the first electronic switch will disconnect the power supply connection with the hard disk and stop supplying power to the hard disk through the small battery; at the same time, the MCU will output a NEN signal to the second electronic switch; after receiving the NEN signal, the second electronic switch will disconnect the power supply connection with the MCU and stop supplying power to the MCU through the small battery. When the first electronic switch and the second electronic switch are disconnected successively, the power supply of the hard disk and the MCU will stop, and the power consumption of the device will return to a state of almost zero power consumption again.

[0041] Furthermore, the high-level signal destruction circuit also includes: a first diode and a second diode, the first diode and the second diode are in an OR gate relationship, and when the MCU and the EC are powered off, the output signal is designed to be a low-level signal.

[0042] The high-level signal destruction circuit also includes a first diode and a second diode, and the first diode and the second diode are connected in an OR gate relationship, which means that as long as the signal passing through any one of the diodes is high, the corresponding operation can be triggered. For example, when any device in the EC or MCU is in working state, the high-level signal outputted by it can pass through one of the two diodes to complete the transmission of the corresponding hard disk destruction trigger signal.

[0043] When the MCU and EC are powered off (such as when the device is in shutdown or low-power state), the circuit is designed to output a low-level signal, which means that when the device is not working, no high-level signal will be continuously output, thus avoiding unnecessary power consumption.

[0044] Further, the method comprises:

[0045] A low-level signal destruction circuit is obtained. The low-level signal destruction circuit has the same electronic component composition as the high-level signal destruction circuit. The MCU and EC output low-level signals to destroy the hard disk, and the first diode and the second diode are in an AND gate relationship. When the EC and the MCU are powered off, the output signal is designed to be a high-level signal.

[0046] Low level signal destroys the circuit Figure 4As shown, the electronic components of the low-level signal destruction circuit and the high-level signal destruction circuit are the same, including a destruction button, a large battery, a small battery, a hard disk, an MCU, an EC, a first electronic switch and a second electronic switch, and a first diode and a second diode. In the low-level signal destruction circuit, when the MCU and the EC are in normal working state, a low-level signal is output to trigger the destruction operation of the hard disk. Unlike the high-level destruction circuit, the first diode and the second diode in the low-level signal destruction circuit adopt an AND gate relationship, that is, the destruction function of the hard disk can only be triggered when the MCU and the EC output low-level signals at the same time. When the device enters the shutdown or low-power state, the MCU and the EC are powered off, and the circuit is designed to output a high-level signal.

[0047] Further, the method comprises:

[0048] The first diode and the second diode are not limited to diodes, and include all devices such as transistors, MOS tubes, and combination circuits that achieve the same function; the first electronic switch and the second electronic switch are not limited to electronic switches, and include all devices such as transistors, MOS tubes, relays, and combination circuits that achieve the same function.

[0049] The first diode and the second diode are not limited to conventional diodes, but may include all components that can achieve the same function, such as triodes, MOS tubes (metal oxide semiconductor field effect transistors) and other devices, or even a combination circuit composed of multiple components. Similarly, the first electronic switch and the second electronic switch are not limited to conventional electronic switches, but may include other components that can achieve the same function, such as triodes, MOS tubes, relays and other devices, which may also be combined into a combination circuit for controlling the on and off of the circuit.

[0050] In summary, the embodiments of the present application have at least the following technical effects:

[0051] First, a high-level signal destruction circuit is obtained. The high-level signal destruction circuit includes a destruction button, a large battery, a small battery, a hard disk, an MCU, an EC, a first electronic switch, and a second electronic switch. Next, a hard disk state destruction model is constructed according to the high-level signal destruction circuit. The hard disk state destruction model includes a hard disk state recognition layer and a soft destruction strategy layer. Then, based on the hard disk state destruction model, a destruction strategy analysis is performed on the target device, and the target hard disk destruction strategy is output. Finally, the target device is subjected to hard disk soft destruction processing according to the target hard disk destruction strategy. The technical problem that the destruction of the hard disk in the prior art requires a large energy consumption is solved. By constructing a high-level signal destruction circuit and a hard disk state destruction model, the technical goal of destroying the hard disk with lower energy consumption is achieved.
