[0015] In the following description, specific details such as particular system architectures and techniques are set forth for illustrative purposes and not for limitation, in order to provide a thorough understanding of the embodiments of this application. However, those skilled in the art will understand that the embodiments of this application can also be implemented in other embodiments without these specific details. In other instances, detailed descriptions of well-known systems, apparatuses, circuits, and methods are omitted so as not to obscure the description of the embodiments of this application with unnecessary detail.

[0016] With the widespread adoption of gigabit fiber broadband, FTTR technology has become the mainstream solution for achieving whole-house gigabit Wi-Fi coverage. As a core infrastructure for building the current smart home ecosystem, FTTR home devices are typically deployed in various rooms of the home, providing users with high-speed network access. To meet users' growing needs for data storage and sharing, most mainstream FTTR home devices now feature storage expansion capabilities, such as connecting storage sticks via USB (Universal Serial Bus) interfaces to achieve instant data storage and retrieval, enabling local data caching, offline downloading, or media sharing services.

[0017] FTTR home-side smart products generally maintain a long-term power-on state to ensure the continuous stability of the whole-house network. Currently, for storage devices mounted on FTTR devices, the traditional solutions in related technologies usually adopt a relatively simple constant power supply method, that is: as long as the FTTR device motherboard is powered on, regardless of whether the storage stick is connected or whether data read and write operations are being performed, its interface power supply is always in a physically connected state. However, this traditional power supply method has the following drawbacks: (1) It lacks a reasonable physical presence detection mechanism, resulting in low energy utilization and unnecessary power consumption of the device. In actual application scenarios, the data read and write of the storage stick has the characteristics of "bursting" and "discontinuous". Most of the time, it is only used as network-attached storage and there is no actual data interaction. When the storage stick is not connected or is in an idle state, the power supply circuit of the FTTR device is still in a continuous power supply state. Its idle power consumption ratio is relatively high. Long-term operation will cause a lot of unnecessary energy consumption and increase the user's electricity expenses. (2) It affects the lifespan of the storage stick and the reliability of data storage. Currently, the mainstream power management solutions usually rely on the hibernation command sent by the operating system to make the storage stick enter "software standby" or "low power mode". However, in this mode, the main control chip inside the memory stick still needs to monitor the interface signals to respond to possible wake-up commands. Therefore, physical power cutoff is not achieved, meaning that the memory stick still consumes milliamps of current in standby mode. Prolonged operation in this state will cause the internal electronic components to remain continuously active, accelerating component aging. This not only shortens the lifespan of the memory stick but may also lead to data read / write errors, data loss, and other problems, impacting the user experience.

[0018] Based on this, embodiments of this application provide an energy-saving control method, system, FTTR device, storage stick, and program product. The FTTR device continuously sends detection signals to the target interface of the storage stick to be connected to determine whether the storage stick is connected. Upon receiving a feedback signal corresponding to the detection signal and confirming that the storage stick is connected to the FTTR device, the FTTR device does not directly supply power to the storage stick. Instead, it verifies the legitimacy of the storage stick's connection based on the detection signal and the feedback signal. Only when the verification result indicates that the storage stick is legally connected will the FTTR device supply power to the storage stick. This avoids energy waste caused by the FTTR device continuously supplying power when the storage stick is not connected, thus saving significant energy consumption. It also prevents equipment damage or data security issues caused by unauthorized connection of the storage stick to the FTTR device, improving security.

[0019] The energy-saving control method, system, FTTR device, memory stick, and program product provided in this application are specifically described through the following embodiments. First, the energy-saving control method in this application embodiment is described.

[0020] Reference Figure 1 , Figure 1 A flowchart illustrating an energy-saving control method applicable to FTTR equipment, as provided in this application embodiment, is shown below. Figure 1 As shown, the energy-saving control method provided in this embodiment includes steps S10 to S40.

[0021] Step S10: Send a detection signal to the target interface of the storage stick to be connected; In this embodiment, the target interface can be a physical interface on the FTTR device specifically designed for plugging in a storage stick, such as a USB interface, a TYPE-C interface, or other types of data interfaces. A storage stick is a plug-and-play micro storage unit designed specifically for FTTR devices, usually referring to NAS (Network Attached Storage) storage modules launched by manufacturers, mainly used to solve the needs of home data backup and sharing. The target interface usually includes multiple pins. The FTTR device can send a detection signal to the pins on the target interface used for data transmission. When a storage stick with a connector adapted to the target interface is plugged into the target interface, the detection signal can be transmitted to the storage stick through the target interface.

[0022] As an example, the energy-saving control method provided in this embodiment can be combined with, for example, Figure 2 Understanding the energy-saving control system shown, the detection signal can be the CC_OUT presence detection output signal provided to the target interface by the SOC (System on Chip) module in the FTTR device through GPIO (General Purpose Input / Output) port 1. After the FTTR device is powered on, the SOC module can continuously send pulse signals to the target interface through CC_OUT. This can be a pre-set set of identification codes, so that the memory stick can receive the detection signal and perform corresponding processing after being connected to the target interface.

[0023] Step S20: In response to receiving a feedback signal from the target interface, determine that the target interface is connected to the storage stick, wherein the feedback signal is obtained by the storage stick connected to the target interface performing preset processing on the detection signal.

[0024] In this embodiment, the detection signal can be pre-processed by the storage stick to generate a corresponding feedback signal. The feedback signal is then transmitted back to the FTTR device through the target interface, allowing the FTTR device to determine that the target interface has been connected to the storage stick based on the feedback signal. The pre-processing is a function that is set in the storage stick during manufacturing and can be implemented by software or hardware. This function enables the storage stick to convert the received detection signal into a feedback signal and output it. Whether the pre-processing can ensure that the detection signal and the feedback signal satisfy a certain relationship determines whether the subsequent legality verification can pass. However, if the storage stick is not connected to the target interface, or the storage stick connected to the target interface is damaged, or the storage stick connected to the target interface cannot perform pre-processing on the detection signal, the verification will fail. In the absence of a feedback signal, the FTTR device will determine that the target interface is not connected to the memory stick because it cannot receive a feedback signal from the target interface. Therefore, the FTTR device in this embodiment can determine whether the target interface is connected to the memory stick by sending a detection signal and receiving a feedback signal, thereby completing the presence detection of the memory stick. If the presence detection result is that the target interface is connected to the memory stick, the FTTR device will execute subsequent steps to further determine whether to supply power to the connected memory stick. Conversely, if the presence detection result is that the target interface is not connected to the memory stick, the FTTR device will not execute subsequent steps or supply power to the target interface, which can avoid energy waste and ensure the safe and stable operation of the FTTR device.

[0025] As an example, such as Figure 2 As shown, the feedback signal can be the CC_IN presence detection input signal received by the SOC module through the GPIO2 port connected to the target interface. The SOC module can determine whether the target interface is connected to the memory stick by continuously monitoring whether the GPIO2 port receives the CC_IN presence detection input signal.

[0026] Step S30: Verify the legality of the access to the storage stick based on the detection signal and feedback signal, and obtain the verification result.

[0027] In this embodiment, when a storage stick is connected to a target interface, the FTTR device can verify the legitimacy of the storage stick connection by comparing the detection signal and the feedback signal. The verification result can include whether the storage stick is legally connected or illegally connected. A legally connected storage stick indicates that it is a legitimate storage stick recognized by the FTTR device, and its built-in preset processing is recognized by the FTTR device, capable of converting the detection signal into a compliant feedback signal, thus passing the legitimacy verification. An illegally connected storage stick indicates that its connector is compatible with the target interface but is incompatible with the FTTR device; the built-in preset processing of an illegal storage stick or illegal peripheral is not recognized by the FTTR device and cannot convert the detection signal into a compliant feedback signal, thus failing the legitimacy verification. By implementing this legitimacy verification, faults such as short circuits and overcurrents caused by the FTTR device supplying power to illegal peripherals can be effectively avoided, as well as data security issues caused by the FTTR device transmitting stored data to illegal peripherals, thus improving security.

[0028] In some feasible embodiments, step S30 above may include: Step S31: Obtain the first level state of the detection signal and the second level state of the feedback signal.

[0029] In this embodiment, the FTTR device can compare the first level state of the detection signal and the second level state of the feedback signal, and use the comparison result as the basis for determining the legality verification result. This is because the memory stick recognized by the FTTR device contains a circuit that can have a specified influence on the level state of the input signal for performing preset processing. The feedback signal is the output signal obtained by the memory stick after the detection signal is input into its internal circuit for performing preset processing and processing. The circuit for performing preset processing can be a loop circuit that makes the first level state and the second level state the same, or an inverting circuit that makes the first level state and the second level state opposite, or other types of circuits that make the first level state and the second level state satisfy a preset relationship. This embodiment does not limit this.

[0030] Step S32: If the first level state and the second level state satisfy the preset relationship, the verification result is that the memory stick is legally connected.

[0031] In this embodiment, if the memory stick is legally connected, the detection signal, after being processed by the memory stick's internal loopback circuit, will produce a compliant feedback signal. In this embodiment, compliance means that the first level state of the detection signal and the second level state of the feedback signal satisfy a preset relationship. Therefore, when the first level state of the detection signal and the second level state of the feedback signal satisfy the preset relationship, it can be determined that the memory stick currently connected to the target interface is a legal memory stick recognized by the FTTR device, containing circuitry for performing preset processing, thus obtaining the verification result of legal memory stick connection. In this embodiment, the circuitry for performing preset processing can be an internal loopback circuit. The preset processing corresponding to a legally connected memory stick involves the memory stick inputting the detection signal to its internal loopback circuit for processing. The corresponding preset relationship is that the level states are the same. For example, if both the first and second level states are high or both are low, the verification result is set as legal memory stick connection; conversely, if the first and second level states are different, the verification result is set as illegal memory stick connection.

[0032] As an example, after the FTTR device is powered on, the SOC module can output a low-level CC_OUT presence detection output signal to the target interface through its own GPIO1 port. When the memory stick is legally connected to the target interface, the GPIO2 port can receive a low-level CC_IN presence detection input signal obtained by the memory stick through preset processing. When the SOC module detects that the level states of the GPIO1 port and the GPIO2 port are the same, it can determine that the memory stick is legally connected.

[0033] In step S40, in response to the verification result indicating that the storage stick is legally connected, power is supplied to the storage stick through the target interface.

[0034] In this embodiment, if the verification result indicates that the memory stick is legally connected, it means that the memory stick has been correctly plugged into the target interface and that the memory stick is a legal memory stick recognized by the FTTR device. If the in-situ detection is correct and the legality verification is passed, the FTTR device can provide power to the memory stick through the pins on the target interface used for transmitting power, so that the memory stick can be powered on and operated.

[0035] In some feasible embodiments, after step S40 above, the energy-saving control method applied to the FTTR device may further include: Step S50: Receive the clock request signal sent by the memory stick through the target interface.

[0036] In this embodiment, after the memory stick is powered on by the power supplied by the FTTR device through the target interface, the memory stick continuously sends a clock request signal to the FTTR device. When the FTTR device has a data interaction requirement, it can notify the memory stick through PCIe (Peripheral Component Interconnect Express, expansion card connector) related signals. At this time, the memory stick pulls the clock request signal high to initiate a handshake and requests the FTTR device to provide a high-frequency clock to support high-speed data transmission. When the FTTR device does not have a data interaction requirement, the memory stick continuously pulls the clock request signal low, so that the FTTR device reduces the power consumption of the memory stick or directly cuts off power depending on the duration of the low level of the clock request signal. The signal state of the clock request signal can reflect whether there is data interaction between the FTTR device and the memory stick in the corresponding time period. When the clock request signal is high, it indicates that there is data interaction between the memory stick and the FTTR device in the corresponding time period; when the clock request signal is low, it indicates that there is no data interaction between the memory stick and the FTTR device in the corresponding time period. Therefore, when the FTTR device receives the clock request signal through the target interface, it can continuously monitor the state changes of the clock request signal to determine whether the memory stick is in an active state that requires frequent data interaction, a short-term idle state that does not require data interaction for a short period of time, or a deep idle state that does not require data interaction for a long period of time. Based on the real-time data interaction needs, it can determine whether the current power supply mode needs to be adjusted to avoid energy waste.

[0037] As an example, such as Figure 2 As shown, the clock request signal can be the CLKREQ signal received by the SOC module through the GPIO3 port connected to the target interface. The SOC module can determine whether it needs to adjust the power supply method to the target interface by continuously monitoring the level of the CLKREQ signal received by the GPIO3 port.

[0038] In step S60, in response to the clock request signal being at a low level for a duration greater than a first preset threshold, a state adjustment command is sent to the memory stick to make the memory stick operate in a low-power mode.

[0039] In this embodiment, the FTTR device can determine whether there is a data interaction requirement on the memory stick by monitoring the level of the clock request signal. When the clock request signal is high, it indicates that there is a data interaction requirement. Conversely, when the clock request signal is low, it indicates that there is no data interaction requirement. Therefore, if the clock request signal remains low for a certain period of time, it indicates that the FTTR device does not need to interact with the memory stick during that period. In this embodiment, a first preset threshold T1 is set as a critical point for this certain period of time. If the duration of the clock request signal being low is greater than the first preset threshold T1, it is considered that the memory stick has been in a short-term idle state. In order to avoid wasting power, the FTTR device will send a state adjustment command to the memory stick to enable ASPM (Active State Power Management) and control the memory stick to enter a low-power mode. Although the FTTR device will continue to supply power to the memory stick at this time, the memory stick's operating mode has been adjusted to a low-power mode, thus reducing power consumption and saving unnecessary energy. Conversely, if the duration of the clock request signal being low is not greater than the first preset threshold T1, the FTTR device can maintain the power supply to the memory stick without interfering with the memory stick's operating mode, thus avoiding frequent adjustments to the memory stick's operating mode due to a short idle state.

[0040] Step S70: After the memory stick is in low power mode, in response to the clock request signal being low for a duration greater than a second preset threshold, power supply to the memory stick is stopped.

[0041] In this embodiment, the FTTR device's continuous monitoring of the clock request signal does not cease even when the memory stick is in low-power mode. If the clock request signal remains low for a certain period even when the memory stick is in low-power mode, it indicates that the memory stick may be in a deep idle state where data interaction is not required for an extended period. Continuing to supply power to the memory stick in this state would be a waste of energy, and to conserve unnecessary power, power supply should be stopped. This embodiment sets a second preset threshold T2 as a critical point for this certain period. After the memory stick enters low-power mode, if the duration of the low clock request signal exceeds the second preset threshold T2, the memory stick is considered to be in a deep idle state, and the FTTR device immediately stops supplying power to the memory stick upon receiving this information. Conversely, after the memory stick is in low-power mode, if the duration of the clock request signal being low is not greater than the second preset threshold T2, it can be determined again whether the duration of the clock request signal being low is greater than the first preset threshold T1. If the duration of the clock request signal being low is greater than the first preset threshold T1, it means that the memory stick is still in a short-term idle state and the data interaction frequency between the FTTR device and the memory stick is not high. In this case, the FTTR device can continue to maintain power supply, and the memory stick can continue to maintain low-power mode. If the duration of the clock request signal being low is not greater than the first preset threshold T1, it means that the data interaction between the FTTR device and the memory stick is relatively frequent. At this time, the low-level timer can be cleared, and the memory stick can be controlled to switch from low-power mode to normal working mode.

[0042] It should be noted that since the first preset threshold T1 and the second preset threshold T2 are the critical thresholds for different stages before and after the memory stick is in low-power mode, they do not need to be correlated. Their specific values ​​can be flexibly configured according to actual needs, and this embodiment does not impose any restrictions on this. Furthermore, the clock request signal involved in this embodiment can also be replaced with an analog signal that supports adjusting the level state and has similar functionality, which can also achieve the adjustment of the memory stick's operating mode.

[0043] In some feasible embodiments, after step S70 above, the energy-saving control method applied to the FTTR equipment may further include: In step S80, in response to the data interaction request for the storage stick, proceed to step S30 above.

[0044] In this embodiment, after the FTTR device stops supplying power to the memory stick, the FTTR device may need to re-interact with the memory stick. In order for the memory stick to respond to the data interaction request of the FTTR device, the memory stick needs to be powered on again. However, before re-supplying the memory stick connected to the target interface, the validity verification process in step S30 above needs to be re-executed. The purpose is to improve the security of data interaction and avoid the situation where the FTTR device directly re-supplyes the faulty memory stick. For example, in the application scenario where the clock request signal is at a low level for a long time due to the memory stick failure and the FTTR device has stopped supplying power to the memory stick, as long as the FTTR device performs the validity verification again before re-supplying power, it can avoid supplying power to the faulty memory stick.

[0045] In some feasible embodiments, the step of stopping power supply to the memory stick in step S70 above may include: adjusting the power supply control signal to turn off the energy-saving control circuit in the FTTR device.

[0046] The energy-saving control circuit is configured to allow or prohibit the external power supply of the FTTR device from supplying power to the target interface. The energy-saving control circuit may include a first switching unit, a voltage divider unit, a second switching unit, and a protection unit. The first switching unit is configured to adjust its own on / off state according to the power supply control signal. The voltage divider unit is configured to adjust the controlled terminal voltage of the second switching unit according to the on / off state of the first switching unit. The second switching unit is configured to adjust the on / off state of the energy-saving control circuit according to the controlled terminal voltage. The protection unit is configured to provide overvoltage protection.

[0047] In this embodiment, the energy-saving control circuit is located between the external power supply and the target interface of the FTTR device. The external power supply can be a 12V DC power supply obtained by converting 220V AC power through the power adapter of the FTTR device. The FTTR device can be powered on by connecting to the external power supply through the power switch. The power supply control signal can be output by the SOC module through the GPIO4 port. This power supply control signal can directly affect the on / off state of the first switching unit, thereby indirectly affecting the on / off state of the second switching unit, and thus adjusting the on / off state of the energy-saving control circuit, which is equivalent to controlling the on / off state of the circuit between the working power supply and the target interface.

[0048] As an example, refer to Figure 3 , Figure 3A schematic diagram of an example structure of the energy-saving control circuit involved in this embodiment is shown. In this embodiment, the power supply control signal can be a valid high-level signal or a low-level signal; the controlled terminal of the first switching unit is connected to the power supply control signal, the first terminal is grounded, and the second terminal is electrically connected to a voltage divider unit, which can be a transistor or a MOSFET (Metal-Oxide-Semiconductor Field-Effect Transistor). Transistor (metal-oxide-semiconductor field-effect transistor) or other switching devices with similar functions; the voltage divider unit may include a first resistor R1 and a second resistor R2, the first end of the first resistor R1 is electrically connected to the second end of the first switching unit, the second end of the first resistor R1 is electrically connected to the first end of the second resistor R2, and the second end of the second resistor R2 is electrically connected to the power supply; the second switching unit may include a gate filter capacitor C1, a bootstrap capacitor C2, a MOSFET VT1, and combined filter capacitors C3, C4, and C5, the first end of the gate filter capacitor C1, the first end of the bootstrap capacitor C2, and the gate of the MOSFET VT1 are connected together with the second end of the first resistor R1 and the first end of the second resistor R2, the second end of the gate filter capacitor C1, the source of the MOSFET VT1, and the second end of the second resistor R2 are connected together and then electrically connected to the power supply, the second end of the bootstrap capacitor C2 is grounded, and the combined filter capacitors C3, C4, and C5 are connected in parallel between the drain of the MOSFET VT1 and ground; the protection unit may include a diode VT2, the anode of the diode VT2 is electrically connected to the drain of the MOSFET VT1, and the cathode of the diode VT2 is electrically connected to the target interface.

[0049] In such Figure 3In the energy-saving control circuit shown, the first resistor R1 and the second resistor R2 can be separate bias resistors, and the MOSFET VT1 can be a P-channel MOSFET power transistor. The source of the MOSFET VT1 is connected to the power supply voltage. When the first switching unit is on, the first terminal of the first resistor R1 is grounded. The first resistor R1 and the second resistor R2 control the voltage division so that the gate of the MOSFET VT1 receives a sufficiently high voltage, driving the MOSFET VT1 to conduct. The power supply voltage provided by the power supply can then reach the target interface through the energy-saving control circuit to power the memory stick. When the first switching unit is off, the first terminal of the first resistor R1 is not connected, the gate of the MOSFET VT1 has no driving voltage, the MOSFET VT1 is off, and the power supply voltage provided by the power supply cannot reach the target interface through the energy-saving control circuit, thereby stopping the power supply to the memory stick. In this embodiment, the gate filter capacitor C1 can filter out high-frequency interference at the gate of the MOSFET VT1, stabilize the gate voltage, and prevent gate malfunction. The bootstrap capacitor C2 can work with the first resistor R1 to increase the rise time of the gate voltage of the MOSFET VT1, accelerate the conduction speed of the MOSFET VT1, and reduce switching losses. As an example, the resistance of R1 can be 18.2KΩ, the resistance of R2 can be 10KΩ, the capacitance of C1 can be 0.1uF, the capacitance of C2 can be 1000pF, and C3, C4, and C5 can use different combinations of capacitance values ​​to achieve wideband filtering. The resistance values ​​of R1 and R2, and the capacitance values ​​of C1 and C2 can also be flexibly selected according to actual needs, as long as the corresponding function is achieved. This embodiment does not impose any restrictions on this. Diode VT2 can be a Schottky diode. When the MOSFET VT1 is turned off quickly, it can use its low forward voltage drop and ultra-fast recovery characteristics to provide a low-impedance discharge path for the parasitic inductance current generated by the downstream load, avoiding voltage spikes from damaging the MOSFET VT1 or downstream sensitive devices. It can also be used to prevent reverse power connection.

[0050] In some feasible embodiments, the energy-saving control circuit in the above embodiments can also be replaced with a dedicated power management chip to achieve higher control accuracy and support dynamic voltage regulation and current limiting, but this will also increase costs.

[0051] This embodiment provides an energy-saving control method applicable to FTTR equipment. By performing presence detection, legality verification, and hierarchical identification of idle states on the memory sticks, and in conjunction with an energy-saving control circuit, it achieves tiered power supply management for the memory sticks. Power is not supplied when the memory stick is not connected or is illegally connected. When the memory stick is briefly idle, it can be controlled to enter a low-power ASPM energy-saving mode. When the memory stick is idle for a long period, power supply can be stopped, significantly reducing the overall power consumption of the FTTR equipment and minimizing unnecessary energy loss. The energy-saving control method provided in this embodiment can be implemented based on hardware circuitry, offering fast response and high reliability. Through the interaction of detection signals and clock request signals with the memory sticks, it achieves automatic power supply, energy saving, and power-off mechanisms, significantly reducing the power-on time of the memory sticks and their cumulative operating time, thereby effectively extending their lifespan and reducing replacement frequency and maintenance costs. This embodiment can determine the legality of the memory sticks plugged into the FTTR equipment through data loopback, preventing power supply to unauthorized peripherals and ensuring the safe use of the FTTR equipment.

[0052] Furthermore, embodiments of this application also provide an energy-saving control method applicable to memory sticks, referring to... Figure 4 , Figure 4 A flowchart illustrating an energy-saving control method applicable to memory sticks, as provided in this application embodiment, is shown below. Figure 4 As shown, the energy-saving control method provided in this embodiment includes steps S100 to S300.

[0053] Step S100: In response to receiving the detection signal sent by the FTTR device through the target interface, the detection signal is processed in a preset manner to obtain a feedback signal.

[0054] In this embodiment, after the storage stick is plugged into the target interface of the FTTR device, it receives a detection signal. The detection signal is a pulse signal continuously provided to the target interface by the FTTR device after it is powered on, and it can be a pre-set set of identification codes. The preset processing is a function set in the storage stick during manufacturing, which can be implemented by software or hardware. This function enables the storage stick to convert the received detection signal into a feedback signal and output it. Whether the preset processing can make the detection signal and the feedback signal satisfy a certain relationship determines whether the subsequent legality verification performed by the FTTR device can pass, and thus determines whether the storage stick can receive the power provided by the FTTR device.

[0055] Step S200: Output a feedback signal to the target interface of the FTTR device. The feedback signal is used by the FTTR device to verify the legality of the access of the storage stick based on the detection signal and the feedback signal, and to supply power to the storage stick through the target interface after the verification result shows that the storage stick is legally accessed. Step S300: Power on based on the power supplied by the FTTR device.

[0056] In this embodiment, after the storage stick provides a feedback signal to the FTTR device, the FTTR device can compare the detection signal and the feedback signal to verify the legitimacy of the storage stick's access. The verification result can include whether the storage stick is legally connected or illegally connected. A legally connected storage stick indicates that it is a legitimate storage stick recognized by the FTTR device, and its built-in preset processing is a processing method recognized by the FTTR device, capable of converting the detection signal into a compliant feedback signal, thus passing the legitimacy verification. An illegally connected storage stick indicates that its connector is compatible with the target interface but is incompatible with the FTTR device, and its built-in preset processing is not recognized by the FTTR device, failing to convert the detection signal into a compliant feedback signal, thus failing the legitimacy verification. After the legitimacy verification performed on the FTTR device is successful, the storage stick can receive power from the FTTR device through the target interface and thus power on and operate.

[0057] In some feasible embodiments, the step of performing preset processing on the detection signal to obtain the feedback signal in step S100 above may include: Step S101: The detection signal is input to the internal loop circuit for processing and a feedback signal is output; wherein, the internal loop circuit includes a 0-ohm resistor.

[0058] In this embodiment, the memory stick may include an internal loopback circuit for performing preset processing. The internal loopback circuit is electrically connected to the connector of the memory stick that plugs into the target interface. When the connector of the memory stick is plugged into the target interface of the FTTR device, the internal loopback circuit can receive the detection signal, perform preset processing on it, and output a feedback signal. Even if the memory stick contains a main control chip or processor, this preset processing does not require intervention from the main control chip or processor; it can be achieved solely through this internal loopback circuit. As an example, such as... Figure 2 As shown, the internal loop circuit of the memory stick can be set as a 0-ohm resistor, that is, the two ends of the 0-ohm resistor are connected to the data receive pin and the data transmit pin on the connector of the memory stick respectively. When the connector of the memory stick is plugged into the target interface, the detection signal will reach one end of the 0-ohm resistor through the data receive pin, and then the feedback signal will be output from the other end of the 0-ohm resistor. The feedback signal can be transmitted back to the target interface through the data transmit pin.

[0059] In some feasible embodiments, the energy-saving control method applied to memory sticks described above may further include: In step S400, a clock request signal is sent to the FTTR device through the target interface, so that the FTTR device controls the operating mode of the memory stick according to the duration of the clock request signal being low.

[0060] In this embodiment, after the memory stick is powered on by the power supplied by the FTTR device through the target interface, it continuously outputs a clock request signal to the FTTR device. When the memory stick receives a PCIe-related signal from the FTTR device, it can know that the FTTR device has a data interaction requirement. At this time, the memory stick will pull the clock request signal high to complete the handshake and request the FTTR device to provide a high-frequency clock to support high-speed data transmission. When the memory stick does not receive a PCIe-related signal from the FTTR device, it means that the FTTR device does not have a data interaction requirement. At this time, the memory stick will continuously pull the clock request signal low so that the FTTR device can reduce the power consumption of the memory stick or directly power off depending on the duration of the clock request signal being low.

[0061] As an example, when the FTTR device is powered normally and sends a state adjustment command based on the state change of the clock request signal, the memory stick will adjust its own operating mode to a low-power mode based on the state adjustment command; when the FTTR device stops powering based on the state change of the clock request signal, the memory stick's operating mode will change to stop working due to the power interruption.

[0062] This embodiment provides an energy-saving control method applicable to memory sticks. After the memory stick is connected to the target interface of an FTTR device, the internal loopback circuit in the memory stick, used for performing preset processing, receives a detection signal and outputs a feedback signal. This quickly informs the FTTR device that the memory stick has been connected to the target interface, allowing the FTTR device to promptly supply power to the legally connected memory stick after successful verification. This reduces unnecessary power consumption caused by the FTTR device continuously supplying power to the target interface over a long period, while also ensuring that the legally connected memory stick can power on and operate normally, thus guaranteeing the safety of both the memory stick and the FTTR device. After the memory stick is powered on by the power provided by the FTTR device, a clock request signal can be continuously sent to the FTTR device, and the level of the clock request signal can be adjusted based on the data interaction requirements of the FTTR device. This allows the FTTR device to continuously monitor the state changes of the clock request signal to determine whether the current power supply method needs to be adjusted, avoiding energy waste.

[0063] The energy-saving control method for memory sticks provided in this embodiment belongs to the same technical concept as the energy-saving control method for FTTR devices provided in the above embodiments. Technical details not described in detail in this embodiment can be found in any of the above embodiments, and this embodiment has the same beneficial effects as any of the above embodiments.

[0064] Furthermore, embodiments of this application also provide an energy-saving control system, which includes an FTTR device and a storage stick, as shown in the reference. Figure 2 ,in: The FTTR device is configured to send a detection signal to the target interface of the memory stick to be connected; The storage stick is configured to, in response to receiving a detection signal, perform preset processing on the detection signal to obtain a feedback signal, and output the feedback signal to the target interface; The FTTR device is configured to, in response to receiving a feedback signal, determine that the target interface is connected to the storage stick; perform a legality verification of the storage stick's access based on the detection signal and the feedback signal, and obtain a verification result; in response to the verification result indicating that the storage stick is legally connected, supply power to the storage stick through the target interface. The storage stick is configured to be powered on based on the electrical power supplied by the FTTR device.

[0065] The energy-saving control system provided in this embodiment can be applied to, for example... Figure 5 The all-optical home networking scenario shown typically employs a distributed networking architecture with one FTTR main gateway and N FTTR sub-gateways to achieve whole-house fiber optic coverage and intelligent networking. The FTTR main gateway connects upstream to the operator's Optical Line Terminal (OLT) via fiber optic cable. As the core of the home network, the FTTR main gateway handles overall management and data forwarding. Downstream, the FTTR main gateway is deployed via cascaded FTTR sub-gateways in various functional areas, such as FTTR sub-gateway 1 in the living room, FTTR sub-gateway 2 in bedroom 1, and FTTR sub-gateway N in the study, achieving whole-house network coverage and ensuring high-speed internet access for home devices such as mobile phones and computers. In this all-optical FTTR home network, storage sticks, as pluggable intelligent expansion accessories, are mounted on the FTTR main gateway and the FTTR sub-gateways in each room, forming a distributed home data storage and service system. FTTR home devices need to be powered on continuously to ensure the stability of the whole-house network. The adapter converts 220V AC voltage to 12V DC voltage to power the FTTR gateway device. FTTR devices are usually equipped with a power switch S, which users can operate to control the power supply to the corresponding FTTR device. FTTR devices power the memory stick and transmit data through USB or TYPE-C interfaces.

[0066] Considering that data interaction between the FTTR device and the memory stick does not occur constantly, and the memory stick is idle most of the time, the energy-saving control system provided in this embodiment also includes an energy-saving control circuit integrated into the FTTR device. After determining that the memory stick is in place and valid, the FTTR device continuously monitors the data activity status of the memory stick and synchronously feeds back the status signal to the energy-saving control circuit, enabling the energy-saving control circuit to execute a differentiated power supply strategy based on the feedback signal. (Refer to...) Figure 6 The overall process of this differentiated power supply strategy may include, for example: Figure 6 Steps S1 to S7 are shown below: Step S1: Power on the FTTR device. At this time, the adapter is plugged into a 220V power supply, the power switch is closed, the FTTR device starts running and executes the program, pulls the in-situ detection output signal low, and waits for the memory stick access signal and subsequent status detection.

[0067] Step S2: The FTTR core module detects the status of the presence detection input signal in real time. If a high level is detected, it is determined that the memory stick is not connected or the device is illegal, and the process returns to step S1, continuously waiting for the memory stick presence signal; if a low level pulse is detected, it is determined that the memory stick is a legal device and has been physically connected, and the process proceeds to step S3.

[0068] Step S3: After receiving the memory stick in-place signal, the FTTR core module pulls the power control signal high. The energy-saving control circuit responds to the signal, turning on the memory stick's power supply circuit to provide the memory stick with its normal operating voltage. The memory stick completes power-on initialization and enters the operational state. At the same time, the FTTR core module begins monitoring the memory stick's clock request signal to determine its operating status.

[0069] Step S4: The FTTR core module continuously monitors the clock request signal output by the memory stick: if the low level duration of the signal does not exceed the threshold T1, it is determined that the memory stick is still in the data interaction / active state, and the process returns to step S3 to maintain the power-saving control circuit on and normal power supply; if the low level duration exceeds the threshold T1, it is determined that the memory stick enters a short-term idle state, and the process proceeds to step S5.

[0070] Step S5: The FTTR core module sends an ASPM (Active State Power Management) enable command to the memory stick, triggering the memory stick's PCIe link to enter a low-power link state. In this state, the memory stick shuts down some of the PCIe link's transmit / receive circuits, reducing link-level idle power consumption while maintaining device presence and rapid wake-up capability. During this stage, the memory stick maintains basic power supply and can respond to data read / write requests at any time. The FTTR core module continues to monitor the clock request signal to determine whether the idle time should be further extended.

[0071] Step S6: After the memory stick enters ASPM mode, the FTTR core module continues to monitor the clock request signal: if the low level duration does not exceed the threshold T2, it is determined that the memory stick is still in a moderately idle state, and the process remains in step S5, maintaining the ASPM low-power mode; if the low level duration exceeds the threshold T2, it is determined that the memory stick has entered a long-term deep idle state, and the process proceeds to step S7.

[0072] Step S7: The FTTR core module pulls the power control signal low, the energy-saving control circuit responds to the signal, and cuts off the power supply circuit of the memory stick to achieve maximum energy saving. If the FTTR device subsequently needs data interaction, the process immediately jumps back to step S2 to re-execute the memory stick presence detection and validity verification. After the presence detection and validity verification pass, the energy-saving control circuit is turned on to restore the power supply to the memory stick and normal operation. If there is no data interaction requirement, the device remains in the off state until the next data request or the memory stick is reinserted.
