In the related art, the restart of the customer pre-installed equipment can only be realized by plugging and unplugging the adapter.

To solve this problem, an embodiment of the present application provides an electronic device 100 . Please refer to FIG. 2 , which is a first structural block diagram of an electronic device provided by an embodiment of the present application. The electronic device 100 in this embodiment is described by taking the customer premises equipment as an example. The electronic device 100 may include a power interface 131 , a function module 110 , an overcurrent 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 integrated on the circuit board for implementing functions.

The power interface 131 is shown as the power interface 131 in FIG. 1 , 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 also 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 inside the electronic device 100 for implementing various functions, 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 services in the electronic device 100 need to be updated and upgraded, or when an abnormal failure such as a crash needs to be restored, a restart signal can be sent through the processor; if the functional module 110 is a radio frequency component, when the electronic device When the 100 fails to achieve network connection or receive radio frequency signals, a restart signal can be sent through the radio frequency components. Of course, when other functional modules 110 in the electronic device 100 need to send a restart signal, the processor in the functional module 110 can send a signal to complete it.

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

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 can be electrically connected to the overcurrent module 120 and the function module 110. When the target current signal is less than the current threshold of the protection chip 130, the protection chip 130 is still in the on state, and the electronic device 100 still maintains the previous working state, that is to say If the target current signal is smaller than the current threshold of the protection chip 130 , the overcurrent protection of the protection chip 130 cannot be triggered.

It can be understood that the target current signal generated by the overcurrent module 120 in this embodiment may be greater than the current threshold of the protection chip 130. At this time, the functional module 110 connected by the protection chip 130 to the protection circuit will not be damaged, and will itself be damaged. In response to the target circuit signal instantaneously, an open circuit is formed. 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 state, so that the control function module 110 is powered off within the first preset time, and after the second preset time, the protection chip 130 is restarted , and control the function module 110 to be powered on.

The power-off can be understood as an open circuit in the circuit of the electronic device 100, and the current cannot form a loop in the circuit. Since the protection chip 130 is in an open circuit state, the current cannot pass through the protection chip 130 to reach the functional module 110, so that the functional module 110 does not work. There is a continuous current to support its normal operation, resulting in a power-down situation. Power-on can be understood as the circuit in the electronic device 100 is in an on state, the current provided by the power supply can form a loop in the entire circuit, and can supply power for the normal operation of the functional module 110, that is, the power-on situation.

It should be noted that, in this embodiment, the electronic device 100 is restarted through the protection mechanism of the protection chip 130 itself for the circuit. Please refer to FIG. 3 , which is a schematic diagram of a protection mechanism of a protection chip in an electronic device provided by an embodiment of the present application.

The power supply is connected to an external device through a DC interface, and the external device supplies power to the electronic device 100 . 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 function module 110, as shown by T1 in FIG. 3 . At this time, the protection chip 130 will change from the on state to the open state in response to the target current signal, and the response time is the first preset time, as shown in T2 in FIG. 3 , within the response time, that is, the first preset time, the protection chip 130 completes the change from the on state to the off state, and can realize the power-off of some functional modules 110 in the electronic device 100. The first preset time is about 100ms, and the specific time can be limited according to the actual situation. After the protection chip 130 triggers the overcurrent protection mechanism, it needs a second preset time to be powered on again. The second preset time can be between 200ms and 500ms. During the second preset time, all the electronic equipment 100 can be The power-off process of the functional module 110 that has not been powered off is shown as T3 in FIG. 3 . By protecting the overcurrent protection function of the chip 130 itself, processing time is reserved for the power-off and power-on processes of the functional module 110, so that the restart of the electronic device 100 does not cause timing disorder.

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 T1 time period is greater than the current threshold of the protection chip 130 , the protection chip 130 triggers the current protection mechanism , the output voltage of the protection chip 130 is in the process of falling within the first preset time, namely, the T2 time period, and is in the falling completion state during the second preset time, that is, the T3 time period, that is, all functional modules 110 are in the power-off state. Wherein, 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-off state. The protection chip 130 may be provided with a detection pin, and the working state of the protection chip is determined according to the level state of the detection pin, and when the level state of the detection pin is a high level state, it is determined that the protection chip is in an open state, and the The control function module 110 is powered off within the 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 the on state, and the control function module 110 is powered on after the second preset time .

Please refer to FIG. 4 and FIG. 5 . FIG. 4 is a second structural block diagram of an electronic device provided by an embodiment of the present application, and FIG. 5 is a schematic structural diagram of an overcurrent module in an electronic device provided by an 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 control tube 121 The third end of the device is connected to the functional module 110 for receiving the control signal transmitted by the functional module 110 .

The control transistor 121 may be a metal oxide semiconductor field effect transistor (MOSFET), MOS field effect transistor for short, which is a device that converts the change of the input voltage into the change of the 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 end and the second end of the control tube 121 are in a disconnected 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 the control signal sent by the function module 110 and adjusts the switch to the closed state based on the control signal, that is, the control tube 121 The first end and the second end are in a conducting state. Since the second end of the control tube 121 is grounded, the overcurrent module 120 will generate a larger target current signal. Based on the target current signal, the target current signal is greater than the protection When the current threshold of the chip is reached, the over-current protection mechanism of the protection chip can be triggered, so that the protection chip is in an open circuit state, so that the power-off and power-on of the functional module 110 are realized through the above-mentioned over-current protection process, thereby realizing the power-off of the electronic device 100. reboot.

Please refer to FIG. 6 . FIG. 6 is a third structural block diagram of an electronic device provided by an embodiment of the present application. The functional module 110 may include a first functional module 111 and a second functional module 112 . The first functional module 111 can be one or more of a radio frequency module, an audio module, and a camera module, and the second functional module 112 can also be one or more of a radio frequency module, an audio module, and a camera module. Of course, the functional module 110 Not limited to radio frequency modules, audio modules, camera modules, but also other functional modules.

It should be noted that when the electronic device 100 is in a normal working state, there will be functional modules that need to work independently among the functional modules included in the functional module 110. If the functional modules that need to work independently and other functional modules work simultaneously, then This can cause short circuits, etc., that can cause electronic equipment to malfunction.

In addition, if the first functional module 111 is not a functional module that needs to work independently, and can work 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 the working state at the same time , it will cause a short circuit and other conditions to cause the electronic equipment to malfunction. Therefore, when the electronic device 100 needs to be restarted, the first functional module 111 and the second functional module 112 can be in a working state at the same time, so that the overcurrent module 120 responds to the first functional module 111 and the second functional module 112. The transmitted control signal can generate a 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, so as to realize the above-mentioned overcurrent protection process. The power-off and power-on of the functional module 110 further realizes the restart of the electronic device 100 .

Of course, when the first functional module 111 and the second functional module 112 are in working state at the same time, a short-circuit state may not necessarily be caused, but the electronic device may still malfunction, so that a current larger than the protection chip 130 can also be generated in the overcurrent module 120 . The target current signal of the threshold value triggers the overcurrent protection mechanism of the protection chip, thereby realizing the power-off and power-on of the functional module 110 through the above-mentioned overcurrent protection process, thereby realizing the restart of the electronic device 100 .

In addition, it should be noted that since the restart function of the electronic device 100 in the related art needs to be realized by manually plugging and unplugging the adapter, it is not convenient. If the contact is not good, there will be misoperation and restart. To solve this problem, the electronic device 100 provided in the embodiment of the present application provides a convenient way of triggering a restart signal for the electronic device.

Specifically, the function module 110 may directly send a restart signal by default when it is detected that the electronic device is faulty or needs to be updated. For example, after the electronic device 100 has downloaded the installation package that needs to be updated, the function module 110 will automatically send a restart signal to complete the update and upgrade of the corresponding function module; for another example, the electronic device 100 encounters a crash, because the electronic device 100 If there is no on/off key, the restart signal can be automatically sent through the state detected by the function module 110; for another example, if the function module 110 in the electronic device 100 cannot work normally, the restart signal can also be automatically sent without the need for For example, the related technology can only complete the restart by plugging and unplugging the adapter.

Please refer to FIG. 7 . FIG. 7 is a fourth structural block diagram of an electronic device provided by an embodiment of the present application. The electronic device 100 may further include a switch assembly 140 , and the switch assembly 140 is electrically connected to the functional module 110 .

When it is detected that the electronic device is faulty or needs to be updated, the function module 110 can be controlled to trigger the function module 110 to send a restart signal, such as closing or opening the switch assembly, so as to restart the electronic device 100 . It can be understood that if the closing switch assembly is set as a condition for triggering the function module 110 to send a restart signal, then when the switch assembly is in an open state, the electronic device 100 is in a normal working state, and no restart operation is required; Under the condition that the function module 110 sends the restart signal, when the switch component is in the closed state, the electronic device 100 is in a normal working state, and no restart operation is 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 issuing a preset control command through a voice component in the electronic device 100 . Wherein, the preset control instruction may be limited according to the actual situation.

As can be seen from the above, in this embodiment, when the electronic device 100 needs to be restarted, the function module 110 can be triggered to send a restart signal in two ways, either automatically or manually, and the overcurrent module 120 receives the restart signal and generates a target current signal. When the current signal is greater than the current threshold of the protection chip 130, the protection chip 130 responds within the first preset time and controls the function module 110 to power off, and restarts after the second preset time, and controls the function module 110 to power on, wherein, The functional module 110 can be completely powered off within the second preset time, and the first preset time and the second preset time are not specifically limited here, and can be set according to actual conditions. By protecting the overcurrent protection function of the chip, processing time is reserved for the power-off and power-on processes of the functional module, so that the restart of the electronic device will not cause timing disorder.

The embodiment of the present application provides a customer pre-installation device. Please refer to FIG. 8 . FIG. 8 is a structural block diagram of a customer front-end device provided by an embodiment of the present application. The customer front-end device 200 may include a power interface 231 , a function module 210 , an overcurrent module 220 and a protection chip 230 .

The power interface 231 is shown as the power interface 131 in FIG. 1 , and the power interface 231 can be connected to an external power source to supply power to the customer premises equipment 200 by using an external device. Of course, a built-in power supply may also be provided inside the customer pre-installation device 200, so as to supply power to the customer-premises equipment 200 through the built-in power supply.

The functional module 210 may be a functional component inside the customer premises equipment 200 for implementing various functions, 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 services in the customer pre-installed equipment 200 need to be updated and upgraded, or when an abnormal failure such as a crash needs to be restored, a restart signal can be sent through the processor; if the functional module 210 is a radio frequency component, when When the customer premise equipment 200 fails to achieve network connection or receive radio frequency signals, a restart signal may be sent through the radio frequency component.

The overcurrent module 220 may be electrically connected to the function module 210, may receive a restart signal sent by the function module 210, and generate a target current signal according to the restart signal. The target current signal is compared with the current threshold of the protection chip 230 to determine the circuit state of the protection chip 230 , and then determine the state of the customer pre-installed device 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 can be electrically connected with the overcurrent module 220 and the function module 210. When the target current signal is less than the current threshold of the protection chip 230, the protection chip 230 is still in the on state, and the customer pre-installation device 200 still maintains the previous working state, and also That is to say, 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 overcurrent module 220 in this embodiment may be greater than the current threshold of the protection chip 230. At this time, the function module 210 connected by the protection chip 230 to the protection circuit is not damaged, and will itself be damaged. In response to the target circuit signal instantaneously, an open circuit is formed. 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 state, so that the control function module 210 is powered off within the first preset time, and after the second preset time, the protection chip 230 is restarted , and control the function module 210 to be powered on.

It should be noted that, in this embodiment, the protection mechanism of the protection chip 230 for the circuit is used to realize the restart of the customer pre-installation device 200 .

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

The control tube can be understood as a switch, that is, when the customer front-end device 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 a disconnected state, and the protection chip 230 is in a stable state. When outputting, the current flowing through the protection chip 230 is in a normal state; when the customer front-end device 200 needs to be restarted, the overcurrent module 220 receives the control signal sent by the function module 210, and based on the control signal, adjusts the switch to the closed state, That is, the first end and the second end of the control tube are in a conducting state. Since the second end of the control tube is grounded, the overcurrent module 220 will generate a larger target current signal. When the 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, so that the power-off and power-on of the functional module 210 can be realized through the above-mentioned overcurrent protection process, thereby realizing customer Restart of the front-end device 200 .

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

It should be noted that, when the customer front-end device 200 is in a normal working state, there will be functional modules that need to work independently among the functional modules included in the functional module 210. If the functional modules that need to work independently work with other functional modules at the same time , it will cause a short circuit and other conditions that will cause the customer's front-end equipment to fail.

In addition, if the first functional module does not belong to the functional module that needs to work independently, and can work simultaneously with other functional modules except the second functional module, but the first functional module and the second functional module are in the working state at the same time, it will cause Short-circuits, etc., cause the customer's front-end equipment to fail. Therefore, when the customer front-end device 200 needs to be restarted, the first functional module and the second functional module can be in a working state at the same time, so that the overcurrent module 220 responds to the data transmitted by the first functional module and the second functional module. The control signal can generate a 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, so as to realize the function module through the above-mentioned overcurrent protection process. The power-off and power-on of the customer premise device 200 are further realized.

In addition, it should be noted that, since the restart function of the customer pre-installed device 200 in the related art needs to be realized by manually plugging and unplugging the adapter, it is not convenient. There will be poor contact, which will cause misoperation to restart. In order to solve this problem, it is more convenient to trigger the restart signal for the customer front-end device 200 in the customer-premise device 200 provided in the embodiment of the present application.

Specifically, the function module 210 may directly send a restart signal by default when detecting that the customer premises equipment 200 is faulty or needs to be updated. For example, after the installation package that needs to be updated has been downloaded in the customer pre-installation device 200, the function module 210 will automatically send a restart signal to complete the update and upgrade of the corresponding functional module; Since the customer front-end device 200 does not have an on/off key, the restart signal can be automatically sent through the state detected by the function module 210; for another example, if the function module 210 in the customer-end device 200 cannot work normally, it is also possible to By automatically sending a restart signal, there is no need to complete the restart by plugging and unplugging the adapter as in the related art.

As can be seen from the above, in this embodiment, when the customer front-end device 200 needs to be restarted, the function module 210 is triggered to send a restart signal, and the overcurrent module 220 receives the restart signal and generates a target current signal. When the target current signal is greater than the protection chip 230 current threshold, the protection chip 230 responds within the first preset time and controls the function module 210 to power off, and restarts after the second preset time, and controls the function module 210 to power on, wherein the second preset time The functional module 210 can be completely powered off within a certain time. By protecting the overcurrent protection function of the chip, processing time is reserved for the power-off and power-on processes of the functional module, so that the restart of the electronic device will not cause timing disorder.

An embodiment of the present application further provides a circuit structure of another customer front-end device. Please refer to FIG. 9 . FIG. 9 is a structural block diagram of another customer front-end device provided by an embodiment of the present application. Wherein, the customer premises equipment 300 may include a power interface 331 , a function module 310 and a protection chip 320 .

The power supply interface 331 is shown as the power supply interface 131 in FIG. 1 , and the power supply interface 331 can be connected to an external power supply to supply power to the customer premises equipment 300 by using an external device. Of course, a built-in power supply may also be set inside the customer pre-installation device 300, so as to supply power to the customer-premises equipment 300 through the built-in power supply.

The functional module 310 may be a functional component inside the customer premises equipment 300 for implementing various functions. If the functional module 310 is a processor, when the services in the electronic device 300 need to be updated and upgraded, or when an abnormal failure such as a crash needs to be restored, a restart signal can be sent through the processor; if the functional module 310 is a radio frequency component, when the electronic device When the 300 fails to achieve network connection or receive radio frequency signals, a restart signal can be sent through the radio frequency components. When the restart signal is sent, the target current signal when the function module 310 is in a normal working state is generated.

The protection chip 320 can be electrically connected to the functional module 310. When the target current signal is greater than the first current threshold of the protection chip 320, the protection chip 320 is in an open circuit state, so that the functional module 310 is controlled to be powered off within the first preset time. ; When the target current signal is less than the first current threshold value of the protection chip 320, the first current threshold value is adjusted to the second current threshold value, and the protection chip 320 is in an open circuit state, so that the control function module is powered off within the first preset time, wherein , the target current signal is greater than the second current threshold; after the second preset time, the protection chip 320 is restarted, and the function module 310 is controlled to be powered on.

The difference between the customer premises equipment 300 provided in this embodiment and the customer premises equipment 200 is that the condition for triggering the restart of the customer premises equipment 300 in this embodiment is to adjust the current threshold of the protection chip 320 . When the customer front-end device 300 is in a normal working state, the current flowing through the protection chip 320 is also normal, but if the customer front-end device 300 needs to be restarted, the current threshold of the protection chip 320 can be reduced to the customer front-end device 300 The magnitude of the target current signal generated in the normal working state will trigger the protection mechanism of the protection chip 320 , so that the protection chip 320 is powered off and restarted, thereby realizing the restart of the customer pre-installation device 300 . For the protection mechanism and the restarting process of the protection chip 320, reference may be made to the above-mentioned embodiments, which will not be repeated here.

For example, when the customer front-end device 300 is in a normal working 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, when the customer front-end device 300 needs to be restarted , the current threshold of the protection chip 320 can be adjusted from B to A. At this time, the current A flowing through the protection chip 320 is the same as its current protection threshold, which will trigger the protection mechanism of the protection chip, so that the protection chip 320 is powered off and restarted. The power is turned off, thereby realizing the restart of the customer premises equipment 300 .
