Detailed Description

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. It is to be understood that the embodiments described are only a few embodiments of the present application and not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without inventive step, are within the scope of the present application.

Referring to fig. 1, fig. 1 is a schematic structural diagram of an electronic device according to an embodiment of the present disclosure. The electronic device may be a Customer Premise Equipment (CPE), or may be other devices, which is not limited herein. The electronic device is described below as the client front-end device 10. The customer premises equipment 10 is used to implement a network access function that can convert the operator public network WAN to the user home local area network LAN. According to the current internet broadband access mode, the access modes can be classified into FTTH (fiber to the home), DSL (digital telephone line access), Cable (Cable television line access), Mobile (Mobile access, i.e. wireless CPE) and the like. The client front-end device 10 is also a mobile signal access device that receives a mobile signal and forwards the mobile signal as a wireless WIFI signal, and is capable of converting a 4G or 5G signal into a WIFI signal, and supporting a plurality of terminal devices, such as a mobile phone, a tablet computer, and the like, to access a network.

In some embodiments, the customer premises equipment 10 includes a housing 11 and a circuit board (not shown) and a radio frequency system disposed in the housing 11 and electrically connected to the circuit board. Further, in the present embodiment, the housing 11 forms a mounting cavity, and the circuit board and the rf system are mounted in the mounting cavity and supported, positioned and protected by the housing 11. In the embodiment shown in fig. 1, the housing 11 is substantially cylindrical, and the external appearance of the customer premises equipment 10 is mainly presented by the housing 11. In other embodiments, the housing 11 may take other shapes such as a prism shape, etc. The circuit board may be provided with a reset key 14 and a plurality of interfaces 13 exposed to the housing 11, the housing 11 is provided with a corresponding reset key 14 and avoidance holes of the interfaces 13, the reset key 14 is exposed to the housing 11 through a corresponding avoidance control, and the touch reset key 14 may restore the factory settings of the customer premises equipment 10. In the embodiment shown in fig. 1, the interface 13 may include at least one of a power interface 131, a USB interface 133, a network cable interface 135, a telephone interface 136, and the like. The power interface 131 is used to connect an external power source to supply power to the client front-end device 10, the USB interface 133 is used for data transmission between the client front-end device 10 and the external device, and the telephone interface 136 is used for external connection of a fixed telephone. Of course, the USB interface 133 and the power interface 131 may be integrated to simplify the arrangement of the interface 13 of the client front end device 10. The network cable interface 135 may further include a wired network access terminal and a wired network output terminal. Customer premises equipment 10 may be connected to the network via a wired network access port and then to other devices via one or more wired network output ports. Of course, in some embodiments, the network interface 135 and the telephone interface 136 may be integrated to simplify the arrangement of the interface 13 of the client front end device 10. Of course, in some embodiments, the wired network output terminal may be omitted, that is, after the client front-end device 10 accesses the network using the wired network input terminal, the wired network is converted into a wireless network (for example, WiFi) by using the radio frequency system, so that the external device can access the network. Of course, both the wired network access terminal and the wired network output terminal may be omitted, and in this embodiment, the customer premises equipment 10 may access a cellular network (also referred to as a mobile network) through the radio frequency system and then convert into a WiFi signal for an external device to access the network.

In some embodiments, the customer premises equipment 10 may implement network access by inserting a SIM card (i.e. an inserted subscriber identity card) without accessing the operator broadband, such as the card socket 102 in the embodiment shown in fig. 1 for carrying the SIM card. The SIM card is inserted into the card socket to access the customer premises equipment, but the card socket usually belongs to a mechanical card socket, and there is a problem that the card socket cannot identify the SIM card in the process of inserting and extracting the SIM card, so that the problem can be solved by providing an embedded subscriber identity module (eSIM) in the customer premises equipment, the eSIM card is directly embedded into a main chip of the customer premises equipment, and is not added into the customer premises equipment as an independent removable component, and a user does not need to insert the SIM card. The eSIM card is an electronic SIM card, can be used as a data file, can be downloaded to the customer premises equipment through a network, has no difference from the SIM card in function, and can enable various electronic products to connect to the internet, talk, send information and the like.

When the service in the client front-end device needs to be updated or upgraded or needs to be recovered when encountering abnormal faults such as crash and the like, the client front-end device needs to be restarted after power failure, however, the common client front-end device does not have a switch key and cannot be restarted by the switch key. In the related art, the restart of the client front-end device can be realized only by plugging and unplugging the adapter.

In order to solve the problem, an embodiment of the application provides an electronic device 100. Referring to fig. 2, fig. 2 is a first structural block diagram of an electronic device according to an embodiment of the present disclosure. The electronic device 100 in this embodiment is described by taking a client front-end device as an example. The electronic device 100 may include a power interface 131, a functional module 110, an over-current module 120, and a protection chip 130. The electronic device 100 may include a circuit structure, and the circuit structure may be integrated on a circuit board, that is, a circuit for implementing functions is integrated on the circuit board.

The power interface 131 is shown in fig. 1 as the power interface 131, and the power interface 131 can be connected to an external power source to supply power to the electronic device 100 by using an external device. Of course, a built-in power supply may be provided inside the electronic device 100 to supply power to the electronic device 100 through the built-in power supply.

The functional module 110 may be a functional component for implementing various functions inside the electronic device 100, for example, the functional module 110 may be a processor, a memory, an audio component, a radio frequency component, a camera component, and the like. If the functional module 110 is a processor, when the service in the electronic device 100 needs to be updated or upgraded or needs to be recovered when encountering an abnormal fault such as a crash, a restart signal may be sent by the processor; if the functional module 110 is a radio frequency component, when the electronic device 100 cannot implement network connection or receive radio frequency signals and other failures, a restart signal may be sent through the radio frequency component. Of course, when the other functional modules 110 in the electronic device 100 need to send the restart signal, the restart may be completed by sending a signal through the processor in the functional module 110.

The overcurrent module 120 may be electrically connected to the functional module 110, and may receive a restart signal sent by the functional module 110, and generate a target current signal according to the restart signal. The target current signal is compared with a current threshold of the protection chip 130 to determine a circuit state of the protection chip 130, and then the state of the electronic device 100 is determined.

The protection chip 130 has the characteristic of overcurrent protection, that is, when the current flowing through the protection chip 130 exceeds the current threshold of the protection chip, the protection device is activated to form an open circuit. The protection chip 130 may be electrically connected to the overcurrent module 120 and the functional module 110, and when the target current signal is smaller than the current threshold of the protection chip 130, the protection chip 130 is still in a pass state, and the electronic device 100 still maintains the previous working state, that is, the target current signal is smaller than the current threshold of the protection chip 130 and cannot trigger the overcurrent protection of the protection chip 130.

It is understood that the target current signal generated by the over-current module 120 in this embodiment may be greater than the current threshold of the protection chip 130, and at this time, the protection chip 130 responds to the target current signal instantaneously to form an open circuit for the functional module 110 connected to the protection circuit to be protected from being damaged. That is, when the target current signal is greater than the current threshold of the protection chip 130, the protection chip 130 is in an open circuit state, so that the functional module 110 is controlled to be powered off within a first preset time, and after a second preset time, the protection chip 130 is restarted and the functional module 110 is controlled to be powered on.

Here, the power-off state can be understood as a state where a circuit in the electronic device 100 is broken and current cannot form a loop in the circuit, and since the protection chip 130 is in the broken state, the current cannot reach the functional module 110 through the protection chip 130, so that the functional module 110 does not have continuous current to support its normal operation, thereby causing a power-off state. The power-on may be understood as that a circuit in the electronic device 100 is in a conducting state, and a current provided by the power supply may form a loop in the whole circuit, so as to supply power for normal operation of the functional module 110, that is, the power-on condition.

It should be noted that, in the present embodiment, the electronic device 100 is restarted by a protection mechanism of the protection chip 130 itself for the circuit. Referring to fig. 3, fig. 3 is a schematic diagram illustrating a protection mechanism of a protection chip in an electronic device according to an embodiment of the present disclosure.

The power supply is connected to an external device through a DC interface, and the electronic device 100 is powered by the external device. When the electronic device 100 needs to be restarted, the overcurrent module 120 generates a target current signal due to the restart signal sent by the functional module 110, as shown by T1 in fig. 3. At this time, the protection chip 130 changes from the on state to the off state in response to the target current signal, and the response time is a first preset time, as shown by T2 in fig. 3, the response time, i.e., the first preset time, the protection chip 130 finishes changing from the on state to the off state, and can realize power down of the part of the functional modules 110 in the electronic device 100, where the first preset time is about 100ms, and the specific time can be limited according to practical situations. After triggering the overcurrent protection mechanism, the protection chip 130 needs a second preset time to power up again, where the second preset time may be 200ms to 500ms, and within the second preset time, a power-down process of all the functional modules 110 that have not been powered down in the electronic device 100 may be implemented, as shown by T3 in fig. 3. Through the overcurrent protection function of the protection chip 130, processing time is reserved for the power-down and power-up processes of the functional module 110, so that the timing sequence disorder cannot be generated during the restart of the electronic device 100.

In addition, in the process of restarting the electronic device 100, as shown in fig. 3, when the target current signal generated by the overcurrent module 120 in the time period T1 is greater than the current threshold of the protection chip 130, the protection chip 130 triggers the current protection mechanism, the output voltage in the protection chip 130 is in a falling process in the first preset time, i.e., the time period T2, and is in a falling completion state in the second preset time, i.e., the time period T3, i.e., all the functional modules 110 are in a power-down state. When the output voltage of the protection chip 130 is at a high level, the protection chip 130 is in a power-on state; when the output voltage of the protection chip 130 is at a low level, the protection chip 130 is in a power-down state. The protection chip 130 may be provided with a detection pin, and determine a working state of the protection chip according to a level state of the detection pin, and when the level state of the detection pin is a high level state, determine that the protection chip is in an open circuit state, and control the power down of the functional module 110 within a first preset time; when the level state of the detection pin is a low level state, it is determined that the protection chip 130 is in a pass state, and the control function module 110 is powered on after a second preset time.

Referring to fig. 4 and fig. 5, fig. 4 is a second structural block diagram of the electronic device according to the embodiment of the present application, and fig. 5 is a schematic structural diagram of an overcurrent module in the electronic device according to the embodiment of the present application. The overcurrent module 120 may include a control tube 121 and a resistor 122. The control tube 121 includes a first end, a second end and a third end, the first end is connected to one end of the resistor 122, and the other end of the resistor 122 is connected to the protection chip 130; the second end of the control tube 121 is grounded; the third end of the control tube 121 is connected to the function module 110, and is configured to receive the control signal transmitted by the function module 110.

The control Transistor 121 may be a Metal Oxide Semiconductor Field Effect Transistor (MOSFET), referred to as MOS field effect Transistor for short, and is a device that converts a change in input voltage into a change in output current.

It can be understood as a switch, that is, when the electronic device 100 does not need to be restarted, the switch is in an off state, that is, the first terminal and the second terminal of the control tube 121 are in an off state, and when the protection chip 130 is in a stable output, the current flowing through the protection chip 130 is in a normal state; when the electronic device 100 needs to be restarted, the overcurrent module 120 receives a control signal sent by the function module 110, and based on the control signal, the switch is turned to a closed state, that is, the first end and the second end of the control tube 121 are in a conducting state, because the second end of the control tube 121 is grounded, the overcurrent module 120 generates a large target current signal, and based on the target current signal, when the target current signal is greater than a current threshold of the protection chip, an overcurrent protection mechanism of the protection chip can be triggered, so that the protection chip is in an open circuit state, and therefore, power-down and power-up of the function module 110 are achieved through the overcurrent protection process, and further, the electronic device 100 is restarted.

Referring to fig. 6, fig. 6 is a third structural block diagram of an electronic device according to an embodiment of the present application. Among them, the function module 110 may include a first function module 111 and a second function module 112. The first functional module 111 may be one or more of a radio frequency module, an audio module, and a camera module, and the second functional module 112 may also be one or more of a radio frequency module, an audio module, and a camera module, of course, the functional module 110 is not limited to the radio frequency module, the audio module, and the camera module, and may also be other functional modules.

It should be noted that when the electronic device 100 is in a normal operating state, functional modules that need to operate independently exist in a plurality of functional modules included in the functional module 110, and if the functional modules that need to operate independently operate simultaneously with other functional modules, a short circuit or the like may be caused, which may cause a failure of the electronic device.

In addition, if the first functional module 111 does not belong to a functional module that needs to operate independently and can operate simultaneously with other functional modules except the second functional module 112, but the first functional module 111 and the second functional module 112 are in an operating state simultaneously, a short circuit or the like may be caused, which may cause a failure of the electronic device. Therefore, when the electronic device 100 needs to be restarted, the first functional module 111 and the second functional module 112 can be simultaneously in an operating state, so that a target current signal can be generated in the overcurrent module 120 in response to the control signal transmitted by the first functional module 111 and the second functional module 112, and when the target current signal is greater than the current threshold of the protection chip, an overcurrent protection mechanism of the protection chip can be triggered to enable the protection chip to be in an open circuit state, so that power-down and power-up of the functional module 110 are realized through the overcurrent protection process, and further, the electronic device 100 is restarted.

Certainly, the first functional module 111 and the second functional module 112 may not necessarily cause a short-circuit state when in the working state at the same time, but may still cause the electronic device to malfunction, so that a target current signal greater than the current threshold of the protection chip 130 may also be generated in the overcurrent module 120 to trigger an overcurrent protection mechanism of the protection chip, thereby implementing powering down and powering up of the functional module 110 through the above-mentioned overcurrent protection process, and further implementing restarting of the electronic device 100.

In addition, it should be noted that, in the related art, the restart function of the electronic device 100 is implemented by manually plugging and unplugging the adapter, which is inconvenient, and if the electronic device is restarted by plugging and unplugging the adapter for a long time, the adapter is seriously worn, poor contact occurs, and thus the electronic device is restarted by misoperation. To solve this problem, the electronic device 100 according to the embodiment of the present disclosure is convenient to trigger a restart signal of the electronic device.

Specifically, the function module 110 may send the restart signal directly by default when detecting that the electronic device is out of order or needs to be updated. For example, after the electronic device 100 downloads an installation package that needs to be updated, the functional module 110 will automatically send a restart signal to complete updating and updating of the corresponding functional module; for another example, when the electronic device 100 is crashed, since the electronic device 100 does not have a switch key, the restart signal may be automatically sent through the state detected by the function module 110; for another example, when the functional module 110 in the electronic device 100 cannot work normally, the restart signal may be automatically sent without the need of completing the restart only by plugging and unplugging the adapter as in the related art.

Referring to fig. 7, fig. 7 is a fourth structural block diagram of an electronic device according to an embodiment of the present application. The electronic device 100 may further include a switch assembly 140, wherein the switch assembly 140 is electrically connected to the function module 110.

When the electronic device is detected to be out of order or needs to be updated, the functional module 110 may be triggered by controlling the switch component to send a restart signal, such as closing or opening the switch component, to restart the electronic device 100. It can be understood that if the condition that the switch component is closed is set as a condition for triggering the functional module 110 to send the restart signal, when the switch component is in the open state, the electronic device 100 is in the normal working state, and the restart operation is not required; if the condition that the switch element is turned on is set as a condition that the trigger functional module 110 sends a restart signal, the electronic device 100 is in a normal working state when the switch element is in a closed state, and a restart operation is not required.

The switch component 140 may be an actual physical key or a virtual key. In addition, the function module 110 may also be triggered to send a restart signal by sending a preset control instruction through a voice component in the electronic device 100. Wherein, the preset control instruction can be limited according to the actual situation.

As can be seen from the above, in the embodiment, when the electronic device 100 needs to be restarted, the function module 110 may be triggered to send a restart signal through an automatic or manual manner, the overcurrent module 120 receives the restart signal and generates a target current signal, and when the target current signal is greater than the current threshold of the protection chip 130, the protection chip 130 responds within a first preset time and controls the function module 110 to power down, and restarts after a second preset time and controls the function module 110 to power up, where the function module 110 may be completely powered down within the second preset time, and the first preset time and the second preset time are not specifically limited herein and are set according to an actual situation. Through the overcurrent protection function of the protection chip, processing time is reserved for the power-off and power-on processes of the functional module, so that time sequence disorder cannot be caused when the electronic equipment is restarted.

The embodiment of the application provides a client front-end device. Referring to fig. 8, fig. 8 is a block diagram of a client front-end device according to an embodiment of the present disclosure. The client front-end device 200 may include a power interface 231, a function module 210, an over-current module 220, and a protection chip 230.

The power interface 231 is the power interface 131 shown in fig. 1, and the power interface 231 can be connected to an external power source to supply power to the client front-end device 200 by using the external device. Of course, a built-in power supply may be provided inside the client front-end device 200 to supply power to the client front-end device 200 through the built-in power supply.

The functional module 210 may be a functional component for implementing various functions inside the client front-end device 200, for example, the functional module 210 may be a processor, a memory, an audio component, a radio frequency component, a camera component, and the like. If the functional module 210 is a processor, when the service in the client front-end device 200 needs to be updated or upgraded or needs to be recovered when encountering an abnormal fault such as a crash, a restart signal may be sent by the processor; if the function module 210 is a radio frequency component, when the client front-end device 200 cannot implement network connection or receive a radio frequency signal or other faults, a restart signal may be sent by the radio frequency component.

The overcurrent module 220 may be electrically connected to the functional module 210, and may receive a restart signal sent by the functional module 210 and generate a target current signal according to the restart signal. The target current signal is compared with a current threshold of the protection chip 230 to determine a circuit state of the protection chip 230, thereby determining a state of the customer premises equipment 200.

The protection chip 230 has the characteristic of overcurrent protection, that is, when the current flowing through the protection chip exceeds the current threshold of the protection chip, the protection device is activated to form an open circuit. The protection chip 230 may be electrically connected to the overcurrent module 220 and the functional module 210, and when the target current signal is smaller than the current threshold of the protection chip 230, the protection chip 230 is still in a pass state, and the client front-end device 200 still maintains the previous working state, that is, the target current signal is smaller than the current threshold of the protection chip 230 and cannot trigger the overcurrent protection of the protection chip 230.

It can be understood that the target current signal generated by the over-current module 220 in this embodiment may be greater than the current threshold of the protection chip 230, and at this time, the protection chip 230 is a functional module 210 connected to the protection circuit and is not damaged, and itself may respond to the target current signal instantaneously to form an open circuit. That is, when the target current signal is greater than the current threshold of the protection chip 230, the protection chip 230 is in an open circuit state, so that the control function module 210 is powered off within a first preset time, and after a second preset time, the protection chip 230 is restarted and the control function module 210 is powered on.

It should be noted that, in this embodiment, the restart of the client front-end device 200 is implemented through a protection mechanism of the protection chip 230 itself for the circuit.

The overcurrent module 220 may include a control tube and a resistor. The control tube comprises a first end, a second end and a third end, the first end is connected with one end of the resistor, and the other end of the resistor is connected with the protection chip 230; the second end of the control tube is grounded; the third end of the control tube is connected to the function module 210 for receiving the control signal transmitted by the function module 110.

The control tube may be understood as a switch, that is, when the customer premises equipment 200 does not need to be restarted, the switch is in an off state, that is, the first end and the second end of the control tube are in an off state, and when the protection chip 230 is in a stable output, the current flowing through the protection chip 230 is in a normal state; when the customer premises equipment 200 needs to be restarted, the overcurrent module 220 receives a control signal sent by the function module 210, and based on the control signal, the switch is adjusted to be in a closed state, that is, the first end and the second end of the control tube are in a conducting state, because the second end of the control tube is grounded, the overcurrent module 220 can generate a larger target current signal, and based on the target current signal, when the target current signal is greater than the current threshold of the protection chip, the overcurrent protection mechanism of the protection chip can be triggered, so that the protection chip is in an open circuit state, and therefore, the power-down and power-up of the function module 210 are realized through the overcurrent protection process, and the restart of the customer premises equipment 200 is further realized.

The functional module 210 may include a first functional module and a second functional module. The first functional module may be one or more of a radio frequency module, an audio module, and a camera module, and the second functional module may also be one or more of a radio frequency module, an audio module, and a camera module, and certainly, the functional module 210 is not limited to the radio frequency module, the audio module, and the camera module, and may also be other functional modules.

It should be noted that when the client front-end device 200 is in a normal operating state, functional modules that need to operate independently exist in a plurality of functional modules included in the functional module 210, and if the functional modules that need to operate independently operate simultaneously with other functional modules, a short circuit or the like may be caused, which may cause a failure of the client front-end device.

In addition, if the first functional module does not belong to a functional module that needs to independently operate, and can operate simultaneously with other functional modules except the second functional module, but the first functional module and the second functional module are in an operating state simultaneously, short circuit and other conditions may be caused, so that the customer premises equipment may malfunction. Therefore, when the customer premises equipment 200 needs to be restarted, the first functional module and the second functional module can be simultaneously in a working state, so that a target current signal can be generated in the overcurrent module 220 in response to the control signals transmitted by the first functional module and the second functional module, and when the target current signal is greater than the current threshold of the protection chip, an overcurrent protection mechanism of the protection chip can be triggered to enable the protection chip to be in an open circuit state, so that the power-down and power-up of the functional modules are realized through the overcurrent protection process, and further, the restart of the customer premises equipment 200 is realized.

In addition, it should be noted that, in the related art, the restart function of the client front-end device 200 is implemented by manually plugging and unplugging the adapter, which is inconvenient, and if the restart function is performed through the plugging and unplugging adapter for a long time, the adapter is seriously worn, poor contact occurs, and the restart function is erroneously operated. To solve this problem, the manner of triggering the restart signal to the client front-end device 200 in the client front-end device 200 according to the embodiment of the present application is more convenient.

Specifically, the function module 210 may send the restart signal directly by default when detecting that the client front-end device 200 has a failure or needs to be updated. For example, after the client front-end device 200 downloads the installation package to be updated, the functional module 210 will automatically send a restart signal to complete the update and update of the corresponding functional module; for another example, when the client front-end device 200 is crashed, since the client front-end device 200 does not have a switch key, a restart signal may be automatically sent through the state detected by the function module 210; for another example, when the function module 210 in the client front-end device 200 cannot work normally, the restart signal may be automatically sent without the need that the restart is completed only by plugging and unplugging the adapter as in the related art.

As can be seen from the above, in this embodiment, when the client front-end device 200 needs to be restarted, the triggering function module 210 sends a restart signal, the overcurrent module 220 receives the restart signal and generates a target current signal, when the target current signal is greater than the current threshold of the protection chip 230, the protection chip 230 responds within a first preset time and controls the function module 210 to power down, and restarts after a second preset time and controls the function module 210 to power up, where the function module 210 can be completely powered down within the second preset time. Through the overcurrent protection function of the protection chip, processing time is reserved for the power-off and power-on processes of the functional module, so that time sequence disorder cannot be caused when the electronic equipment is restarted.

The embodiment of the present application further provides another circuit structure of a client front-end device, please refer to fig. 9, and fig. 9 is a block diagram of another structure of a client front-end device according to the embodiment of the present application. The client front-end device 300 may include a power interface 331, a functional module 310, and a protection chip 320.

The power interface 331 is shown as the power interface 131 in fig. 1, and the power interface 331 can be connected to an external power source to supply power to the client front-end device 300 by using an external device. Of course, a built-in power supply may be provided inside the client front-end device 300 to supply power to the client front-end device 300 through the built-in power supply.

The functional module 310 may be a functional component for implementing various functions inside the client front-end device 300. If the functional module 310 is a processor, when the service in the electronic device 300 needs to be updated or upgraded or needs to be recovered when encountering an abnormal fault such as a crash, a restart signal may be sent by the processor; if the functional module 310 is a radio frequency component, when the electronic device 300 cannot implement network connection or receive radio frequency signals and other failures, a restart signal may be sent through the radio frequency component. The target current signal when the function module 310 is in a normal operation state is generated while the restart signal is transmitted.

The protection chip 320 may be electrically connected to the functional module 310, and when the target current signal is greater than a first current threshold of the protection chip 320, the protection chip 320 is in an open circuit state, so as to control the functional module 310 to be powered down within a first preset time; when the target current signal is smaller than a first current threshold of the protection chip 320, adjusting the first current threshold to a second current threshold, and the protection chip 320 is in an open circuit state, so that the functional module is controlled to be powered off within a first preset time, wherein the target current signal is larger than the second current threshold; after the second preset time, the protection chip 320 is restarted and controls the functional module 310 to be powered on.

The difference between the customer premises equipment 300 and the customer premises equipment 200 provided in the present embodiment is that the condition for triggering the restart of the customer premises equipment 300 in the present embodiment is to adjust the current threshold of the protection chip 320. When the customer premises equipment 300 is in a normal operating state, the current flowing through the protection chip 320 is also normal, but if the customer premises equipment 300 needs to be restarted, the current threshold of the protection chip 320 can be reduced to the size of the target current signal generated in the normal operating state of the customer premises equipment 300, and then the protection mechanism of the protection chip 320 is triggered, so that the protection chip 320 is powered off and restarted and powered on, and the restart of the customer premises equipment 300 is realized. For the protection mechanism and the restart process of the protection chip 320, reference may be made to the above embodiments, which are not described herein again.

For example, when the customer premises equipment 300 is in a normal operating state, the current flowing through the protection chip 320 is a, and the current threshold of the protection chip 320 is B, where B is greater than a, and when the customer premises equipment 300 needs to be restarted, the current threshold of the protection chip 320 may be adjusted from B to a, and at this time, the current a flowing through the protection chip 320 is the same as the current protection threshold thereof, and then a protection mechanism of the protection chip may be triggered, so that the protection chip 320 is powered off and restarted and powered on, thereby restarting the customer premises equipment 300.
