Detailed Description

It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the scope of the application.

It should be noted that, at present, the mountain village headphone is endless, because the left and right headphone components have independent characteristics, the left and right headphone components can be used normally even if exchanged, and further there is a risk that the components are packaged, which not only damages the interests of manufacturers, but also damages the interests of consumers. Therefore, how to identify whether the left and right earphone parts in the earphone are original parts is a problem to be solved.

In order to solve the above-mentioned drawbacks, the present embodiment provides a method for identifying an original component of a headphone, which is applied to a first component, and the first component is used in cooperation with a second component. Because the second component is an original component in this embodiment, a feedback signal can be generated and sent according to the received preset original component serial number, and then when the first component and the second component are successfully connected, the preset original component serial number can be sent to the second component first, whether the feedback signal sent by the second component can be received within the first preset time period is judged, and whether the second component is an original component is determined based on the judging result, so that whether left and right earphone components in the earphone are original components is realized.

For easy understanding, a method for identifying an original component of a headphone according to an embodiment of the present application and a headphone according to the following embodiments will be specifically described with reference to fig. 1 to 8.

An embodiment of the present application provides a method for identifying an original component of a headset, referring to fig. 1, fig. 1 is a flowchart of a first embodiment of the method for identifying an original component of a headset, as shown in fig. 1, in this embodiment, the method may be applied to a first component of a headset, and the headset may further include a second component that is used in cooperation with the first component. In the present embodiment, the above-described method can of course also be applied to an in-ear earphone or the like, and the present embodiment is not limited thereto. This implementation is explained with headphones, and the above-mentioned headphones can realize functions such as broadcast audio through the cooperation of left side sound production part (left earphone) and right side sound production part (right earphone).

It should be understood that the first component and the second component may be connected by a wired manner, or may be connected by a wireless manner, which is not limited in this embodiment. When the first component 1 and the second component 2 are connected by a wired connection, referring to fig. 2, fig. 2 is a schematic diagram of connection of the headset in the method for identifying an original component of the headset according to the present application, as shown in fig. 2, a wire harness 3 (i.e. a headset part in the headset) may be disposed between the first component 1 and the second component 2, and power supply and communication between the first component 1 and the second component 2 may be achieved through the wire harness 3; when connected in a wireless manner, the first component 1 and the second component 2 may be connected by bluetooth or the like to achieve communication. The present embodiment is described using headphones, but is not limited thereto. Further, in this embodiment, the headset may include a first component 1, a second component 2, and a wire harness 3, where the first component 1 may be a left sound emitting component or a right sound emitting component of the headset, and the second component 2 may be another sound emitting component.

As shown in fig. 1, in this embodiment, the method includes:

Step S10: and when the connection with the second component is successful, transmitting a preset original component serial number to the second component.

It is understood that the method of the present embodiment may be performed by any one of the headphone components, such as the left side sound component or the right side sound component in the headphone, having the function of at least two sound components being used in cooperation with each other. In this embodiment, the above-mentioned left sound emitting component is used as the first component 1, and the right sound emitting component is used as the second component 2, that is, the execution body of this embodiment is the first component 1, so as to implement the identification of the original component of the second component 2.

For convenience of the following description, referring to fig. 3, fig. 3 is a block diagram of a headphone in the method for recognizing an original component of a headphone according to the present application.

It will also be appreciated that a power supply 221 may be provided in the first component 1 or in the second component 2, and that power may be supplied to the first component 1 as well as to the second component 2 via the power supply 221. As shown in fig. 3, this embodiment is described using the second member 2 having the power supply 221 provided therein, but this is not a limitation.

In fig. 3, the first component 1 may include a first processing module 11, where the first processing module 11 may be formed by a Programmable logic device (Complex Programmable Logic Device, CPLD), but may also be formed by a device such as a Field-Programmable gate array (Field-Programmable GATE ARRAY, FPGA) or a microcontroller (Microcontroller Unit, MCU), and the present embodiment is not limited thereto, and the method for identifying a headset original component provided in the present embodiment may be performed by the above-described first processing module 11.

The second component 2 may comprise a power supply unit 22 with a power supply 221, the power supply unit 22 being connectable to a load in the second component 2 that needs to be powered, and also being connectable to the first processing module 11 of the first component 1 via the wire harness 3. In actual use, when the first processing module 11 in the first component 1 receives the electric energy provided by the power source 221 in the second component 2, it can be explained that the first component 1 and the second component 2 are successfully connected, and the first processing module 11 starts to work to perform the subsequent operation of identifying the original components of the headphone.

In the case of performing the headphone original component recognition, the first processing module 11 may acquire a serial number corresponding to the first component 1 and a serial number corresponding to the second component 2, which are original components with respect to the first component 1, and transmit the serial number of the second component 2 to the second component 2 as the preset original component serial number.

Before actual use, a manufacturer may set a preset original component serial number specific to the component according to different components, and store the preset original component serial number and the preset original component serial number of the component used with the component together in the component. As further shown in fig. 3, in this embodiment, the first component 1 may further include: a storage module 12;

wherein the first processing module 11 is connected to the memory module 12 and the second component 2, respectively;

The first processing module 11 is configured to transmit, when the connection with the second component 2 is successful, the preset original component serial number stored in the storage module 12 to the second component 2.

It should be noted that the Memory module 12 may be formed by a device having a Memory function, such as an EEPROM (ELECTRICALLY ERASABLE PROGRAMMABLE READ-Only Memory) or a Flash Memory (Flash Memory), which is not limited in this embodiment. The storage module 12 may be configured to store a serial number corresponding to the first component 1 and a serial number corresponding to the second component 2.

It should be noted that, the first processing module 11 may be provided with a serial number reading pin, and the first processing module 11 may be connected to the storage module 12 through the serial number reading pin; meanwhile, the first processing module 11 may be further provided with signal transmission pins (i.e., TX and RX in fig. 3), and the first processing module 11 may be connected to the second component 2 through the signal transmission pins.

In a specific implementation, after the first processing module 11 receives the electrical energy provided by the second component 2 through the wire harness 3, the first processing module 11 determines that the connection with the second component 2 is successful, the first processing module 11 starts to work after being powered on and initialized, reads the serial number corresponding to the second component 2 stored in the storage module 12 through the serial number reading pin, uses the serial number as a preset original component serial number, generates a pulse signal according to the preset original component serial number, and transmits the pulse signal to the second component 2 through the signal transmission pin TX of the first processing module 11.

As another implementation manner, the first processing module 11 may further use the serial number corresponding to the first component 1 as a preset original component serial number, and generate a pulse signal according to the preset original component serial number and send the pulse signal to the second component 2.

As another implementation manner, the first processing module 11 may generate a pulse signal together with the serial number corresponding to the first component 1 and the stored serial number corresponding to the second component 2, and send the pulse signal to the second component 2.

As another implementation manner, the first processing module 11 may also obtain an identification signal that may be used to represent the original component, besides the serial number, and generate a pulse signal to send to the second component 2.

Step S40: judging whether a feedback signal is received within a first preset time length;

when the second component is an original component, the feedback signal is sent to the first component according to the received preset original component identification signal;

Step S50: and determining whether the second component is an original component based on the judging result.

It will be appreciated that the feedback signal may be a signal indicative of the receipt of the predetermined original component serial number by the second component 2. In this embodiment, the second component 2 may be configured to generate a feedback signal after receiving the serial numbers of all preset original components, and transmit the feedback signal to the signal transmission pin RX of the first processing module 11; further, if the second component 2 is an original component, the second component 2 may have the above function, and the second component 2 may generate a feedback signal based on the preset original component serial number, and transmit the feedback signal to the first processing module 11; if the second component 2 is not an original component, it indicates that the second component 2 does not have the function, and further, a feedback signal cannot be generated based on the preset original component serial number and sent to the first component 1. The first processing module 11 can thus determine whether the second component 2 is an original component based on determining whether a feedback signal sent by the second component 2 is received.

In order to prevent the first processing module 11 from waiting for the second component 2 to generate the feedback signal, in this embodiment, a timer may be disposed in the first processing module 11, and when the first processing module 11 transmits the preset original component identification signal to the second component 2, the timer starts to count, and the first processing module 11 may determine whether the feedback signal is received within the first preset period; if the feedback signal is not received within the first preset time period, the second component 2 can be judged to be not an original component and to be an original component; if the feedback signal is received within the first preset time period, it may be determined that the second component 2 is an original component. The first preset duration can be set according to practical situations, and the embodiment adopts 30s for explanation. The first processing module 11 is therefore also configured to determine that the second component 2 is an original component when the feedback signal is received within the second preset time period.

Further, considering that when the second component 2 is not an village component, it may also be a component that is produced by the manufacturer of the first component 1 but is not original with respect to the first component 1 (i.e. is a subsequent original plant component), in order to further determine whether the second component 2 is an original plant component or an original component, in this embodiment, the second component 2 may be configured to generate, when receiving a preset original component serial number, a feedback signal based on a target serial number, that is, the feedback signal is a signal generated by the second component 2 when receiving the preset original component serial number based on the target serial number;

Further, the step S50 includes:

step S51: and determining whether the second component is a factory component or not based on a judging result, wherein the factory component is a component produced by a manufacturer of the first component.

It should be understood that the target serial number may be a serial number corresponding to the first component 1 that is original with respect to the second component 2, and a serial number corresponding to the second component 2, and may be stored in the second component 2.

In actual use, after the second component 2 receives the pulse signal sent by the first processing module 11, no matter the second component 2 is a factory component or an original component, a feedback signal can be generated according to the target serial number corresponding to the first component 1 stored by the second component and sent to the first component 1;

When the first component 1 does not receive the feedback signal within the first preset time period, the second component 2 can be judged to be an village component; when the first component 1 receives the feedback signal within the first preset time period, it may indicate that the second component 2 has the functions of receiving the preset original component serial number and sending the feedback signal, and then it may be determined that the second component 2 is a factory component, that is, the manufacturer of the second component 2 is the same as the manufacturer of the first component 1.

Step S52: and when the second component is an original plant component, determining whether the second component is an original component according to a preset expected serial number and the feedback signal.

The preset expected serial number may be a serial number corresponding to the second component 2 when the second component 2 stored in the first component 1 is an original component.

In actual use, after the first processing module 11 determines that the second component 2 is an original plant component, the feedback signal may be decoded, and since the feedback signal is generated based on the target serial number stored in the second component 2, the target serial number of the second component 2 may be obtained by further decoding, and then the preset original component serial number of the second component 2 stored in the first component 1 is used as the preset expected serial number, and the target serial number is compared with the preset expected serial number; if the first and second parts 1 and 2 are identical, it is determined that the second part 2 is an original part of the first part 1, and if the first and second parts 2 are not identical, it is determined that the second part 2 is an original part of the first part 1 and is not an original part, thereby further realizing the identification of the original part.

Similarly, when the serial number received by the second component 2 is the serial number corresponding to the first component 1, it is also determined whether the serial number is the same as the stored target serial number, and the specific process is the same as the above, which is not described in detail in this embodiment.

Further, when the first component 1 determines that the second component 2 is an original component, the first processing module 11 may conduct a power supply loop between a power input end and a load in the first component 1, so that the second component 2 may transmit the electric energy provided by the internal power supply 221 to the load of the first component 1 through the power input end, so that the first component 1 starts to operate; when the second component 2 is not an original component, then the reception of the electrical energy provided by the second component 2 is prohibited.

When the second component 2 is an original component in the embodiment, after receiving a preset original component serial number, a feedback signal is generated and sent based on a target serial number, and when the first component 1 and the second component 2 are successfully connected, the preset original component serial number can be sent to the second component 2 first, and whether the feedback signal sent by the second component 2 can be received within a first preset time period is judged; if not, the second component 2 can be judged as an village component; if yes, the second component 2 can be judged to be the original plant component; then decoding the feedback signal to determine whether the target sequence number is a preset expected sequence number; if not, the second component 2 may be determined to be the original plant component but not the original package component; if so, the second component 2 can be judged to be an original component, so that the identification of whether the left and right earphone components in the earphone are the original components is realized.

In addition, in order to achieve the above objective, an embodiment of the present application further provides a method for identifying a headset original component, and referring to fig. 4, fig. 4 is a flowchart of a second embodiment of the method for identifying a headset original component according to the present application.

In this embodiment, the above method is applicable to the second part 2 in a headset, wherein the second part 2 is used in cooperation with the first part 1. Note that, the second member 2 in the present embodiment may be the second member 2 in the first embodiment, and the first member 1 in the present embodiment may be the first member 1 in the first embodiment.

As shown in fig. 4, in this embodiment, the method includes:

step S20: when the connection with the first component is successful, judging whether a preset original component serial number sent by the first component is received within a second preset time length;

step S30: and determining whether the first component is an original component based on a judgment result.

It is understood that the method of the present embodiment may also be performed by any one of the headphone components, such as the left side sound component or the right side sound component in the headphone, having the function of at least two sound components being used in cooperation with each other. Based on the first embodiment, the present embodiment can be described using the left sound emitting component as the first component 1 and the right sound emitting component as the second component 2, that is, the main body of the method for recognizing a headphone original component according to the present embodiment is the second component 2, and the headphone original component is recognized on the first component 1.

As further shown in fig. 3, in the present embodiment, the second processing module 21 and the power supply unit 22 with the power supply 221 may be disposed in the second component 2; wherein the power source may be connected to the first processing module 11 of the first component 1 via the wire harness 3, and the power source 221 may also be connected to the second processing module 21 to supply power to the second processing module 21.

It should be understood that the second processing module 21 may be formed by a CPLD, or may be formed by a device such as an FPGA or an MCU, and the present embodiment is not limited thereto, and the method for identifying the original components of the headset provided in the present embodiment may be performed by the second processing module 21.

Also, the second processing module 21 may be provided with signal transmission pins (i.e., TX and RX in fig. 3), and thus the second processing module 21 may be connected to the first processing module 11 through the signal transmission pins, specifically, the TX pin of the second processing module 21 may be connected to the RX pin of the first processing module 11, and the RX pin of the second processing module 21 may be connected to the TX pin of the first processing module 11.

In this embodiment, when the first component 1 is an original component, a preset original component serial number may be sent; therefore, when the power supplied by the power source 221 of the second component 2 is transmitted to the first processing module 11 of the first component 1, it can be determined that the connection with the first component 1 is successful; when the second processing module 21 receives the serial number of the original component sent by the TX pin of the first processing module 11 through the RX pin, it can determine that the first component 1 is the original component; if not, it can be determined that the first component 1 is not an original component, thereby realizing the identification of whether the left and right earphone components in the earphone are original components.

Also, in order to prevent the second processing module 21 from waiting for the first component 1 to send the preset original component serial number, in this embodiment, a timer may be also provided in the second processing module 21, and when the second processing module 21 is successfully connected to the first component 1, the timer starts to count, and the second processing module 21 may determine whether the preset original component serial number is received within a second preset period of time; if not, it can be determined that the first component 1 is not an original component and is an original component; if so, it can be determined that the second member 2 is an original member. The second preset duration can be set according to practical situations, and the embodiment adopts 30s for explanation. The second processing module 21 is therefore operable to determine that the first component 1 is an original component when a predetermined original component serial number is received within a second predetermined period of time.

Further, in order to enable the first component 1 to determine whether the second component 2 is an original component, in this embodiment, after the step of determining whether the predetermined original component serial number sent by the first component is received within the second predetermined period of time, the method further includes:

Step S21: and when the preset original part serial number is received in the second preset time period, sending the generated feedback signal to the first part, so that the first part determines whether the second part is the original part according to the feedback signal.

It should be noted that the feedback signal may be the feedback signal mentioned in the first embodiment, which is not described in detail in this embodiment.

In this embodiment, after the second processing module 21 receives the serial number of the original component in the second preset time period, a feedback signal may be generated and transmitted to the RX pin of the first processing module 11 through the TX pin of the second processing module 21; after receiving the feedback signal, the first processing module 11 can determine that the second component 2 is also an original component.

It should be emphasized that, since the specific determination process has been described in the first embodiment, specific reference may be made to the first embodiment, and this embodiment is not repeated.

Further, it is also considered that when the first component 1 is not an original component, it may also be a component that is produced by the manufacturer of the second component 2 but is not original with respect to the second component 2 (i.e., a subsequent original plant component), so in order to further determine whether the first component 1 is an original plant component or an original component, in this embodiment, the step of sending the generated feedback signal to the first component 1 when the preset original component serial number is received within the second preset time period includes:

Step S211: and when the preset original part serial number is received in the second preset time period, judging that the first part is an original part, and the original part is a part produced by a manufacturer of the second part.

It can be understood that the second processing module 21 can decode the pulse signal sent by the first processing module 11 after receiving the pulse signal, and if the second processing module 21 can receive the original component serial number obtained by decoding within the second preset time period, it can determine that the first component 1 is a factory component, that is, the manufacturer of the first component 1 is the same as the manufacturer of the second component 2; if the first component 1 is not received within the second preset time period, the first component 1 can be judged to be an village component.

Step S212: and judging whether the preset original part serial number is a target serial number or not.

It should be understood that the second processing module 21 may store therein the serial number of the second component 2 and the serial number of the first component 1, which is an original component with respect to the second component 2, as the target serial number. After the second processing module 21 decodes and obtains the preset original component serial number sent by the first processing module 11, it can be determined whether the preset original component serial number is the target serial number stored in the second processing module 21; further, it is determined whether the first component 1 is an original component.

Step S213: if yes, the first component is judged to be an original component, and a feedback signal generated based on the target serial number is sent to the first component.

When the second processing module 21 determines that the preset original component serial number is inconsistent with the target serial number, it may determine that the first component 1 is an original plant component, but not an original component; when the second processing module 21 determines that the preset original component serial number matches the target serial number, it may determine that the first component 1 is an original component.

After determining whether the first component 1 is a factory component or an original component, in order to make the first component 1 determine whether the second component 2 is a factory component or an original component, the second processing module 21 may generate a feedback signal according to the stored target serial number corresponding to the second component 2 and transmit the feedback signal to the first processing module 11, so that the first processing module 11 may determine whether the second component 2 is a factory component or an original component according to the received feedback signal.

It should be emphasized that the specific determining process has been described in the first embodiment, so that the specific description of the first embodiment is referred to, and the detailed description of the embodiment is omitted.

Further, after the second component 2 determines that the first component 1 is an original component, the second processing module 21 may conduct the power supply loop between the power supply 221 and the first component 1, and transmit the power provided by the power supply 221 to the first component 1 to supply power to the first component 1; if the first component 1 is not an original component, the supply of electric power to the first component 1 is prohibited.

In addition, in order to achieve the above objective, the present embodiment further proposes a headset, and referring to fig. 5, fig. 5 is a block diagram of a first embodiment of the headset of the present application.

As shown in fig. 5, in the present embodiment, the above-mentioned headphone includes a first member 1 and a second member 2 that are used in cooperation with each other;

The first component 1 is configured to transmit a preset original component serial number to the second component 2 when the connection with the second component 2 is successful;

The second component 2 is configured to determine that the first component 1 is an original component when the preset original component serial number is received within a second preset time period, and send a generated feedback signal to the first component 1;

The first component 1 is further configured to determine that the second component 2 is an original component when the feedback signal is received within a first preset duration.

The first member 1 may be connected to the second member 2 via a wire harness 3.

In a specific implementation, after the first component 1 is successfully connected with the second component 2 through the wire harness 3, the first component 1 can transmit the stored preset original component serial number to the second component 2 through the wire harness 3; if the second component 2 receives the preset original component serial number within the second preset time period, the second component 2 can determine that the first component 1 is an original component and generate a feedback signal to be transmitted to the first component 1 through the wire harness 3; if the first component 1 receives the feedback signal within the first preset time period, the first component 1 may determine that the second component 2 is an original component.

Further, as further shown in fig. 5, the first component 1 includes: a first processing module 11 and a storage module 12;

the first processing module 11 is configured to transmit, when the connection with the second component 2 is successful, a preset original component serial number stored in the storage module 12 to the second component 2;

the first processing module 11 is further configured to determine that the second component 2 is an original component when the feedback signal is received within a first preset duration.

For ease of understanding, description is made with reference to fig. 6 to 8, fig. 6 is a schematic circuit diagram of a first embodiment of the headphone of the present application, fig. 7 is a flowchart of the first member 1 in the first embodiment of the headphone of the present application, and fig. 8 is a flowchart of the second member 2 in the first embodiment of the headphone of the present application.

As shown in fig. 6 and 7, in the present embodiment, the first processing module 11 is described as a CPLD, and the memory module 12 is described as an EEPROM.

In a specific implementation, after the CPLD receives the electrical energy provided by the second component 2 through the wire harness 3, the CPLD determines that the connection with the second component 2 is successful (i.e. the first component 1 in fig. 7 detects the connection with the wire harness 3), and starts to work after power-on initialization, reads the serial number of the preset original component corresponding to the second component 2 stored in the EEPROM through the serial number reading pin, generates a pulse signal according to the serial number of the preset original component, and then transmits the pulse signal to the second component 2 through the signal transmission pin TX of the CPLD, and starts to count through the timer (i.e. the CPLD in fig. 7 acquires the serial number of the preset original component from the EEPROM and transmits the pulse signal through the TX pin, and simultaneously starts to count).

The CPLD may then determine whether the RX pin has received a feedback signal within 30 seconds (i.e., whether the RX pin in FIG. 7 has received a feedback signal within 30 seconds); if so, the second component 2 can be judged to be the original plant component; if not, the second component 2 can be judged to be an village component; when it is determined that the second component 2 is a factory component, the CPLD may decode the feedback signal to determine whether the target sequence number therein is a preset expected signal (i.e., whether the sequence number in the feedback signal in fig. 7 is a preset expected sequence number); if so, it can be determined that the second member 2 is an original member.

Further, as further shown in fig. 5, the second part 2 includes: a second processing module 21;

wherein the second processing module 21 is connected with the first processing module 11;

The second processing module 21 is configured to determine that the first component 1 is an original component when the preset original component serial number is received within a second preset time period, and send the generated feedback signal to the first processing module 11.

As shown in fig. 6 and 8, in the present embodiment, the second processing module 21 is illustrated by using an MCU, the power supply 221 in the power supply unit 22 is illustrated by using a battery, and the battery may be connected to the MCU, and the battery may be connected to the CPLD.

In a specific implementation, after the MCU detects that the battery transmits the electric energy to the CPLD through the wire harness 3, the MCU starts timing (i.e. when the second component 2 in fig. 8 detects that the battery is connected to the wire harness 3), the MCU starts timing, and the MCU starts to determine whether a pulse signal is received within 30s and decodes to obtain a preset original component serial number (i.e. whether the MCU in fig. 8 receives a pulse signal within 30s through the RX pin and decodes to obtain a preset original component serial number); if the first component 1 is received within 30s, it may be determined that the first component is a factory component, and a feedback signal is generated according to the target serial number and sent to the CPLD through the TX pin at the same time (i.e., the feedback signal is sent to the CPLD through the TX pin in fig. 8), so that the CPLD determines whether the second component 2 is the factory component according to the feedback signal; if the first component 1 is not received within 30 seconds, it can be determined that the first component 1 is an village component.

Then the MCU can judge whether the preset original part serial number obtained by decoding is a target serial number (namely, whether the preset original part serial number in the figure 8 is the target serial number); if so, the first component 1 can be judged as the original component; if not, the first component 1 can be determined to be the factory component.

Further, in order for the first component 1 to allow operation after determining that the second component 2 is an original component, as shown in fig. 5, the first component 1 further includes: a buffer module 13 and a first switch module 14; the second part 2 comprises: a power supply unit 22;

wherein the buffer module 13 is respectively connected with the first switch module 14 and the power supply unit 22, and the first switch module 14 is also respectively connected with the first processing module 11 and the load;

The buffer module 13 is configured to buffer the electric energy provided by the power supply unit 22, and transmit the buffered electric energy to the first switch module 14;

The first processing module 11 is further configured to transmit the generated switching signal to the first switching module 14 when it is determined that the second component 2 is an original component;

The first switch module 14 is configured to transmit the buffered electric energy to the load for supplying power when the switch signal is received.

It can be appreciated that the buffer module 13 can be used to buffer the electric energy provided by the power unit 22, so as to avoid the sudden access of the electric energy to damage the circuit and prolong the service life. The load may be a load in the first part 1 that requires use of electric energy other than the module shown in fig. 5, such as a speaker, etc., to which the present embodiment is not limited.

In this embodiment, as shown in fig. 6, the buffer module 13 may be configured by two not gates and one voltage follower VF, but may be configured by other components. The first switch module 14 may be configured by a switch tube, and of course, may also be configured by a Load switch chip.

Further, in order to manage the received electric energy, as shown in fig. 5, in this embodiment, a first power management module 15 may be further disposed in the first component 1, where the first power management module 15 is connected to the first switch module 14 and the load, respectively. The first power management module 15 may be a module for distributing power, and may specifically be a chip with a power management unit (Power Management Unit, PMU), or may be a chip with other similar functions, which is not limited in this embodiment. As shown in fig. 6, this embodiment is illustrated using PMU (i.e., PMU1 in fig. 6).

In a specific implementation, when the buffer module 13 receives the electric energy transmitted by the second component 2, the electric energy can be buffered, and the buffered electric energy is transmitted to the first switch module 14; when the first processing module 11 determines that the second component 2 is an original component, it can generate a switch signal to the first switch module 14; after receiving the switching signal, the first switch module 14 may conduct the loop between the buffer module 13 and the first power management module 15, so as to transmit the buffered electric energy to the first power management module 15, and the first power management module 15 transmits the buffered electric energy to the load for supplying power. When the first processing module 11 determines that the second component 2 is not an original component, the switch signal is not generated, and the load is not operated.

Further, as further shown in fig. 5, in order to allow the transmission of electric energy to the first component 1 only when the first component 1 is determined to be an original component, in this embodiment, the second component 2 further includes: a current limiting module 23 and a second switching module 24;

Wherein the second processing module 21 is respectively connected with the second switch module 24, the current limiting module 23 and the power supply unit 22, the current limiting module 23 is further connected with the second switch module 24, and the second switch module 24 is further connected with the buffer module 13 and the power supply unit 22;

The second switching module 24 is configured to switch the current mode to the power supply mode when the mode switching signal is received, and transmit the power provided by the power supply unit 22 to the buffer module 13 when the on signal is received.

The current limiting module 23 may be formed by a resistor and a switch tube, and as shown in fig. 6, the second switch module 24 may be formed by a Load switch chip, or may be formed by a switch tube, and this embodiment is described by using a Load switch chip.

In order to manage the power supplied by the power source 221, as shown in fig. 5, in this embodiment, the power source unit 22 further includes: a power supply 221, a voltage regulation module 222, and a second power management module 223; the second power management module 223 is connected to the power source 221 and the voltage adjustment module 222, and the voltage adjustment module 222 is further connected to the first processing module 11, the second processing module 21, and the second switching module 24.

The power supply 221 may be constituted by a battery; the second power management module 223 may be configured to manage the power provided by the battery, and may also be configured by a PMU (i.e., PMU2 in fig. 6); the voltage adjusting module 222 can perform voltage adaptation and voltage stabilization on the electric energy provided by the battery to obtain stable required electric energy, and can be composed of a low dropout linear voltage regulator (Low Dropout Regulator, LDO), and can be composed of other components, and the embodiment adopts the LDO for description.

In a specific implementation, after the second processing module 21 determines that the first component 1 is an original component, a current setting signal may be generated and transmitted to the current limiting module 23, and a conducting signal may be generated and transmitted to the second switching module 24; the current limiting module 23 may generate a mode switching signal to the second switching module 24 after receiving the current setting signal; the second switch module 24 may switch the current mode from the low power consumption low current mode to the full current mode after receiving the mode switching signal, and transmit the adjusted electric energy output by the voltage adjustment module 222 to the buffer module 13 when receiving the on signal, so as to supply power to the first component 1. When the second processing module 21 determines that the first component 1 is not an original component, no current setting signal and no on signal are generated, and the second switching module 24 does not supply power to the first component 1.

The first switching tube Q1 may be an NMOS tube or a PMOS tube, and this embodiment is described with reference to an NMOS tube.

It should be understood that the control pin of the CPLD (i.e., GPIO3 in fig. 6) may be connected to the control terminal of the first switching tube Q1 to implement the transmission of the switching signal.

In fig. 6, the non-inverting input terminal of the voltage follower VF receives the electrical energy sent by the second switching module 24, and after the electrical energy is transmitted to the first NOT gate NOT1 and the second NOT gate NOT2 by the voltage follower VF, the buffering of the electrical energy is completed, and then the electrical energy is transmitted to the input terminal of the first switching tube Q1; when the CPLD determines that the second component 2 is not an original component, no switching signal is generated at a control pin of the CPLD (i.e., the CPLD sets the GPIO3 state to 0 (low level) in fig. 7), the first switching tube Q1 is kept off, and the load does not work (i.e., the system in fig. 7 is turned off); when the CPLD determines that the second component 2 is an original component, the control pin of the CPLD generates a switching signal and transmits the switching signal to the control end of the first switching tube Q1 (i.e., the CPLD sets the GPIO3 state to 1 (high level)) in fig. 7, the first switching tube Q1 is turned on, and the buffered electric energy is transmitted to the PMU2, and the PMU2 is retransmitted to the load, so that the load works (i.e., the system in fig. 7 works normally).

Further, as further shown in fig. 6, in the present embodiment, the current limiting module 23 includes: the first resistor R1, the second resistor R2, the third resistor R3 and the second switching tube Q2;
