[0097] Here, exemplary embodiments will be described in detail, and examples are shown in the drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present disclosure. On the contrary, they are merely examples of methods consistent with some aspects of the present disclosure as detailed in the appended claims.

[0098] Such as Figure 1As shown, an embodiment of the present disclosure provides a power supply control method, which is executed by a control module of an electronic device. The method includes:

[0099] S201: Generate a control instruction;

[0100] S202: Encrypt the control instruction according to a key commonly known to the power supply module of the electronic device to obtain a ciphertext instruction;

[0101] S203: Send the ciphertext instruction to the power supply module of the electronic device, where the ciphertext instruction is used to control the power supply of the power supply after being decrypted by the power supply module.

[0102] The electronic device in this embodiment can be an electronic device including a control module and a power supply module. The control module is originally used for information processing of the electronic device.

[0103] Here, the electronic device provided by the embodiment of the present disclosure can be various types of electronic devices, and the electronic device can be a terminal device or a server. Exemplarily, the terminal device can include: a mobile terminal and a fixed terminal, where the mobile terminal includes: a tablet computer, a notebook computer, etc.; the fixed terminal includes: a personal computer (Personal Computer, PC), etc. The PC can include a desktop PC, a notebook computer, or a large-screen display device, etc. The server can be: a rack-mounted server and / or a blade server.

[0104] In some embodiments, the electronic device can be an Information Technology (IT) device. The IT device includes various devices participating in IT computing. For example, the IT device can be a device serving as a blockchain node.

[0105] In some embodiments, the electronic device at least includes a control module and a power supply module. The control module can include a processor. In some embodiments, the control module further includes a memory, and the memory is connected to the processor. An executable application program is stored in the memory for the processor to execute control instructions.

[0106] The power supply module can at least include a power supply, and the power supply can include: various rechargeable batteries. The battery can include: a lithium battery and / or a sodium battery. The power supply module can also include a battery management system (Battery Management System, BMS) for managing the battery. The power supply module can also include, but is not limited to: a power supply chip, an inverter power supply, a DC power supply, a battery, etc.

[0107] Exemplarily, the processor in the processing module of the electronic device includes, but is not limited to: a central processing unit, a microcontroller, an embedded controller, and / or an image processor.

[0108] Exemplarily, the control instruction of the electronic device is an instruction recognizable by the control module and the power supply module of the electronic device, which is an agreed instruction between the two. The power supply module controls the output voltage, power supply power, and power supply current of the power supply according to the control instruction. Exemplarily, the control instruction includes, but is not limited to: a voltage reduction instruction, a voltage increase instruction, and / or a voltage holding instruction. Additionally exemplarily, the control instruction includes, but is not limited to: a power supply power increase instruction, a power supply power reduction instruction, an instruction to increase the power supply current, and / or an instruction to reduce the power supply current.

[0109] In the embodiment of the present disclosure, multiple communications can occur between the control module and the power supply module of the electronic device.

[0110] Exemplarily, when the electronic device is in the working state, the control module of the electronic device can send multiple control instructions to the power supply module of the electronic device. It can be understood that communication is maintained between the control module and the power supply module at all times, and the power supply module supplies power to the electronic device according to the control instruction, so that the electronic device can work properly.

[0111] In the embodiment of the present disclosure, the control module generates a control instruction, and encrypts the control instruction according to a key known to both the control module and the power supply module to obtain a ciphertext instruction. The power supply module determines whether to supply power to the load according to the decrypted control instruction.

[0112] The key can be a key pre-configured in the power supply module and the control module, or a key pre-negotiated between the power supply module and the control module. In short, before the control instruction is interacted between the control module and the power supply module, it is necessary to ensure that both parties know the key.

[0113] The control module generates a plaintext control instruction in S201, and encrypts the plaintext control instruction with the key in S202 to obtain an encrypted instruction, and this encrypted instruction is the ciphertext instruction. Without decryption, the ciphertext instruction is a jumble of characters or a string whose meaning cannot be understood by a third party, etc.

[0114] By encrypting the control instruction, only when the power supply module of the electronic device can normally decrypt the control instruction can the power supply operation be performed, reducing the high-power power supply provided by the power supply module in response to overclocking when the electronic device is overclocked. If the power supply module does not provide high-power power supply, the electronic device will be forced to exit the overclocking working mode due to insufficient power supply, reducing the phenomena of many failures and short service life caused by the electronic device working in the overclocking mode for a long time.

[0115] In some embodiments, the control module sends a control instruction to the power supply module, and the power supply module returns a response instruction to the control module according to the control instruction, so that the electronic device works stably. Specifically, when the control module sends a correct instruction to the power supply module, the power supply module controls the power supply according to the control instruction, and the electronic device can work normally; when the control module sends an incorrect instruction to the power supply module, the power supply module cannot recognize the instruction and cannot supply power, so the electronic device cannot work normally. Through the interaction of instruction information between the control module and the power supply module, it is ensured that only the control module of this electronic device can normally use the power supply module for power supply.

[0116] In some embodiments, the control module sends an encrypted control instruction 1 to the power supply module, and the power supply module returns an encrypted response instruction to the control module according to the control instruction 1; the control module sends an encrypted control instruction 2 to the power supply module, and the power supply module returns an encrypted response instruction to the control module according to the control instruction 2; and so on.

[0117] In the embodiments of the present disclosure, the control module and the power supply module of the electronic device communicate according to a communication protocol. The communication protocol is a communication rule agreed in advance between the control module and the power supply module, and is a rule and agreement that must be followed to complete communication or services. Exemplarily, the communication protocol includes, but is not limited to, Transmission Control Protocol / Internet Protocol (TCP / IP), NetBios Enhanced User Interface (NETBEUI), Internetwork Packet Exchange / Sequences Packet Exchange (IPX / SPX).

[0118] In some embodiments, the control module and the power supply module can periodically update the key. In this way, every once in a while, the key known to both the control module and the power supply module is changed once, so as to reduce the risk of a third party stealing the key and controlling the power supply of the power supply module, thus enhancing the power supply security of the power supply module.

[0119] In some other embodiments, as Figure 2 shown, the method further includes:

[0120] S101: After the electronic device is started, generate the key;

[0121] S102: Send the key to the power supply module.

[0122] After each startup of the electronic device, the control module generates a key. That is, every time the electronic device starts up, a new key is generated. Thus, the lifespan of a key is the current startup of the electronic device.

[0123] After each startup of the electronic device, a new key is generated. On the one hand, it realizes the dynamic update of the key, which can improve the power supply security of the power supply module compared with static passwords. On the other hand, generating the key after startup can also reduce unnecessary key generation and update.

[0124] In one embodiment, the method further includes:

[0125] Receiving overclocking power supply feedback information;

[0126] When receiving the overclocking power supply feedback information, updating the key.

[0127] For example, if the power supply module determines that it has entered the overclocking power supply mode according to its own power supply parameters, it sends overclocking power supply feedback information to the control module. However, when the control module finds that it has not sent a control instruction to the power supply module to make it enter the overclocking power supply mode, it can be considered that the current key has been leaked. At this time, the control module will update the key and send the updated key to the power supply module to improve the power supply security of the power supply module.

[0128] The overclocking power supply mode can be: the power supply mode of the power supply module when the electronic device is working in the overclocking mode. The power supply power of the power supply module in the overclocking power supply mode is greater than that in the non-overclocking power supply mode; or, the power supply voltage of the power supply module in the overclocking power supply mode is greater than that in the non-overclocking power supply mode. The non-overclocking power supply mode is: the power supply mode when the electronic device is in the normal frequency or low frequency mode.

[0129] In the embodiments of the present disclosure, the key sent to the power supply module can be an encrypted key and / or an unencrypted key, that is, the key can also be sent in plaintext or ciphertext.

[0130] If the key is sent in ciphertext, a pre-set static password can be used to encrypt the key generated after the startup of the electronic device. For example, use the serial number (Serial Number, SN) of the battery included in the power supply module, or the serial number of the CPU of the processing module to encrypt the key generated after the startup of the electronic device. If the SN of the battery is used to encrypt the key, the SN of the battery can be stored in the memory of the control module in advance, for example, stored in the read-only memory (Read Only Memory, ROM) of the control module. If the serial number of the CPU is used to encrypt the key, the SN of the CPU is pre-stored in the memory of the power supply module.

[0131] In some embodiments, an encryption flag is added to the communication protocol, and the control module of the electronic device sends a flag indicating whether the key is sent in plaintext or ciphertext to the power supply module, facilitating the power supply module to quickly identify the encryption status of the key.

[0132] If the encryption flag indicates encryption, the key sent by the control module of the electronic device is in ciphertext;

[0133] If the encryption flag indicates non-encryption, the key sent by the control module of the electronic device is in plaintext.

[0134] By adding an encryption flag to the communication protocol, the key exchange communication between the control module and the power supply module of the electronic device becomes more flexible. Exemplarily, the encryption algorithm can be various pre-agreed algorithms, including but not limited to the Message-Digest Algorithm (MD5) and the Data Encryption Standard (DES).

[0135] In some embodiments, as Figure 3 shown, S101 may include:

[0136] S1011: After the electronic device is started, obtain a random number;

[0137] S1012: Use the random number as the input parameter of the key generation algorithm to generate the key.

[0138] In the embodiments of the present disclosure, after the electronic device is started, a random number is obtained.

[0139] This random number is generated by various random algorithms. Exemplarily, the random number includes but is not limited to true random numbers, which have characteristics such as randomness, unpredictability, and non-repeatability. True random numbers have advantages such as high efficiency, low resource consumption, and reliable random number generation. There is no limit on the number of digits of the random number. Exemplarily, the number of digits of the random number can be 32 bits or other numbers of digits.

[0140] In some embodiments, after the electronic device is started, a true random number can be generated according to the sensors in the AC environment. There is no limit on the number of digits of the true random number. Exemplarily, the number of digits of the true random number can be 32 bits or other numbers of digits.

[0141] In some embodiments, using the random number as the input parameter of the key generation algorithm, through relevant algorithms, the key is generated. There are various algorithms for generating the key. Exemplarily, they include but are not limited to the Message-Digest Algorithm (MD5) and the Data Encryption Standard (DES).

[0142] Using a random number as the input of the key generation algorithm, the generated key has randomness. In this way, the probability that any two generated keys are the same is random, thereby reducing the regularity of the key generated according to the input parameters with a certain pattern and reducing the reason for insufficient security caused by this regularity.

[0143] In some embodiments, the input parameters of the key generation algorithm may include one or more. If there are multiple input parameters, in addition to the random number, the input parameters may further include the number of times the key is generated. In this way, the randomness of the generated key is ensured by using the random number, and at the same time, the different probability between two adjacent generated keys is further increased by using the number of times of generation.

[0144] In some embodiments, S1011 may include: the control module generates a random number by itself.

[0145] In some embodiments, as Figure 4 shown, S1011 may include:

[0146] S10111: After the electronic device is started, send a request message to the power supply module;

[0147] S10112: Receive the random number returned by the power supply module based on the request message.

[0148] After the electronic device is started, the control module of the electronic device sends a request message to the power supply module, and the control module receives the random number returned by the power supply module based on the request message.

[0149] In the embodiments of the present disclosure, in order for the electronic device to work properly, it needs to obtain a random number after being started. If the acquisition of the random number fails, the electronic device cannot work properly; after the acquisition of the random number is successful, the electronic device can work properly.

[0150] After the electronic device is started, it sends a request message to the power supply module to obtain the random number returned by the power supply module. After the electronic device is started, it communicates with the power supply module of the electronic device, so that the electronic device has no chance to overclock during subsequent operation.

[0151] It can be understood that since the electronic device needs to be powered by the power supply module when it works, the control module of the electronic device needs to send a request message to the power supply module. After receiving the request message sent by the control module, the power supply module parses the request message according to the agreed communication protocol. If the content of the request message is normally parsed, the power supply module generates a random number and returns it to the control module; if the power supply module cannot normally parse the request message or cannot recognize the content of the request message, the power supply module cannot generate a random number.

[0152] The control module sends a request message to cause the power supply module to generate a random number. Understandably, only when receiving a request from the control module can the power supply module return the random number to the control module. The random number generated through the communication between the control module and the power supply module reduces the possibility of the random number being leaked, further enhancing the power supply security of the power supply module.

[0153] In the embodiments of the present disclosure, the random number returned by the power supply module can be in plaintext or ciphertext.

[0154] If the random number is in ciphertext, a pre-set static password can be used to encrypt the random number returned by the power supply module. For example, the serial number (SN) of the battery included in the power supply module, or the serial number of the CPU of the processing module is used to encrypt the random number returned by the power supply module. If the SN of the battery is used to encrypt the random number, the SN of the battery can be stored in the memory of the power supply module in advance. If the serial number of the CPU is used to encrypt the random number, the SN of the CPU is pre-stored in the memory of the power supply module.

[0155] In some embodiments, a mark indicating whether to encrypt is added to the communication protocol, and the power supply module of the electronic device sends a mark indicating whether the random number is in plaintext or ciphertext to the control module, facilitating the control module to quickly identify the encryption status of the random number.

[0156] If the encryption mark indicates encryption, the random number received by the control module of the electronic device is in ciphertext;

[0157] If the encryption mark indicates non-encryption, the random number received by the control module of the electronic device is in plaintext.

[0158] By adding a mark indicating whether to encrypt to the communication protocol, the communication between the control module and the power supply module of the electronic device becomes more flexible and convenient. Exemplarily, the encryption algorithm can be various agreed-upon algorithms, including but not limited to the Message-Digest Algorithm (MD5), Data Encryption Standard (DES).

[0159] In some embodiments, the S202 may include:

[0160] Encrypt the control instruction and the dynamically determined preset information to obtain the ciphertext instruction.

[0161] In the embodiments of the present disclosure, for different times, the ciphertext instructions obtained by encrypting the same control instruction by the control module with a key may result in the same encrypted ciphertext instructions. In this way, if a third party steals the ciphertext instruction and sends it to the power supply module, it may cause the possibility of overclocking power supply.

[0162] Therefore, in the embodiments of the present disclosure, dynamic preset information is introduced. While generating control instructions, the preset information is also dynamically determined. Each time a control instruction is generated, the preset information is determined once. Thus, the life cycle of a preset information is one communication of a control instruction. Since a third party cannot simulate the preset information dynamically determined by the control module, it is ensured that each encrypted ciphertext instruction is different, improving the reliability of the interaction of control instructions between the control module and the power supply module.

[0163] While generating control instructions, the preset information is dynamically determined, realizing the dynamic update of the preset information. Compared with static preset information or without introducing preset information, the security and reliability of control instruction encryption can be improved.

[0164] In some embodiments, the preset information includes at least one of the following:

[0165] Random number;

[0166] The instruction generation time information of the control instruction;

[0167] The instruction generation sequence number of the control instruction.

[0168] In the embodiments of the present disclosure, the preset information is an element used for encrypting together with the control instruction.

[0169] In some embodiments, while generating control instructions, the generated preset information is a random number, and the random number is a unique identifier. The random number includes but is not limited to true random numbers. True random numbers have characteristics such as randomness, unpredictability, and non-repeatability. True random numbers have advantages such as high efficiency, low resource consumption, and reliable random number generation. There is no limit to the number of digits of the random number. Exemplarily, the number of digits of the random number can be 32 bits or other numbers of digits.

[0170] Exemplarily, the power supply module and the control module can agree on the number of digits of the random number. The number of digits of the random number can be used by the power supply module to determine whether the control instruction is a control instruction generated by the control module. If the number of digits of the random number is inconsistent with the agreed number of digits, it indicates that the ciphertext instruction may be an insecure instruction.

[0171] In other embodiments, while generating control instructions, the generated preset information is the instruction generation time information of the control instruction, and the time information is a unique identifier. Exemplarily, the time information includes year, month, day, hour, minute, second, and millisecond.

[0172] Exemplarily, this generation time information can be used by the power supply module to determine whether the control instruction is a newly generated control instruction by the control module. If the time difference between the generation time indicated by this generation time information and the current time is greater than a preset value, it indicates that the ciphertext instruction may be an insecure instruction.

[0173] In some other embodiments, while generating control instructions, the generated preset information is a sequential number, which is a unique identifier. Exemplarily, when the electronic device is started, the sequence number starts counting from 0, and each time a control instruction is generated, the sequence number is incremented by 1. The life cycle of the sequence number is one start-up of the electronic device, ensuring that the sequence number is not repeated during one start-up and operation of the electronic device.

[0174] Exemplarily, this sequential number can facilitate the power supply module to determine whether the received ciphertext instruction was an old or counterfeited ciphertext instruction based on the ciphertext instructions it has already received. For example, if the current sequential number is not consecutive with the number in the previously executed ciphertext instruction, the power supply module may consider this ciphertext instruction as an abnormal instruction, and then the control module will receive an abnormal feedback.

[0175] As Figure 5 shown, an embodiment of the present disclosure provides a power supply control method, which is executed by the power supply module of the electronic device. The method includes:

[0176] S401: Receive the control instruction to be executed sent by the control module;

[0177] S402: When the instruction to be executed is a ciphertext instruction, decrypt the ciphertext instruction according to the key jointly known to the control module of the electronic device;

[0178] S403: If the ciphertext instruction is successfully decrypted, perform a power supply operation according to the decrypted control instruction.

[0179] Exemplarily, the power supply module controls the output voltage, power supply power, and supply current of the power supply according to the control instruction. Exemplarily, the control instruction includes but is not limited to: a voltage reduction instruction, a voltage increase instruction, and / or a voltage holding instruction. Additionally, exemplarily, the control instruction includes but is not limited to: a power supply power increase instruction, a power supply power reduction instruction, an instruction to increase the supply current, and / or an instruction to reduce the supply current.

[0180] In the embodiment of the present disclosure, encrypted communication is performed between the control module and the power supply module of the electronic device.

[0181] Exemplarily, when the electronic device is in the working state, the power supply module of the electronic device can receive the control instructions to be executed sent by the control module multiple times. It can be understood that the control module and the power supply module maintain communication at any time, and the power supply module supplies power to the electronic device according to the control instruction, so that the electronic device can work properly.

[0182] The key can be a key pre-configured in the power supply module and the control module, or a key pre-negotiated between the power supply module and the control module. In short, before the control instructions are exchanged between the control module and the power supply module, it is necessary to ensure that both parties know the key.

[0183] The instructions to be executed received by the power supply module only support encrypted instructions. Without decryption, the encrypted instructions are a jumble of characters or strings whose meaning cannot be understood by a third party, etc.

[0184] By encrypting the instructions to be executed, power supply operations can only be performed when the power supply module of the electronic device can normally decrypt the control instructions, reducing the high-power supply provided by the power supply module in response to overclocking when the electronic device is overclocked. If the power supply module does not provide high-power supply, the electronic device will be forced to exit the overclocking working mode due to insufficient power supply, reducing the phenomena of multiple failures and short service life caused by the electronic device working in the overclocking mode for a long time.

[0185] In the embodiments of the present disclosure, the control module and the power supply module of the electronic device communicate according to a communication protocol. The communication protocol is a communication rule agreed upon in advance by the control module and the power supply module, and is a rule and agreement that must be followed to complete communication or services. Exemplarily, the communication protocol includes, but is not limited to, Transmission Control Protocol / Internet Protocol (TCP / IP), NetBios Enhanced User Interface (NETBEUI), Internetwork Packet Exchange / Sequences Packet Exchange (IPX / SPX).

[0186] In some embodiments, the control module and the power supply module can periodically update the key. In this way, every once in a while, the key commonly known between the control module and the power supply module is changed once, thereby reducing the risk of a third party stealing the key and controlling the power supply of the power supply module, thus enhancing the power supply security of the power supply module.

[0187] In other embodiments, as Figure 6 shown, the method further includes:

[0188] S404: When the instruction to be executed is a plaintext instruction, reject the execution of the plaintext instruction;

[0189] In the embodiments of the present disclosure, the power supply module of the electronic device receives the control instruction sent by the control module. The control instruction only supports encrypted instructions. If the control instruction is a plaintext instruction, it is rejected; if the control instruction is an encrypted instruction, the encrypted instruction is decrypted in accordance with the control module of the electronic device. If the encrypted instruction is successfully decrypted, the power supply operation is performed according to the decrypted control instruction.

[0190] In some other embodiments, such as Figure 7 shown, the method further includes:

[0191] S301: Receive a request message sent after the electronic device is started;

[0192] S302: Generate a random number according to the request message;

[0193] S303: Send the random number to the control module;

[0194] S304: Receive the key generated by the control module according to the random number.

[0195] In some embodiments, the power supply module receives a request message sent after the electronic device is started and generates a random number according to the request message. It can be understood that only when the request message sent after the electronic device is started is received, the power supply module can return the random number to the control module. The random number generated by the communication between the control module and the power supply module reduces the possibility of the random number being leaked and further improves the power supply security of the power supply module.

[0196] The random number is generated by using various random algorithms. Exemplarily, the random number includes but is not limited to a true random number, and the true random number has characteristics such as randomness, non-inferability, and non-repeatability. The true random number has advantages such as high efficiency, low resource occupancy, and reliable random number generation. There is no limitation on the number of digits of the random number. Exemplarily, the number of digits of the random number can be 32 bits or other numbers of digits.

[0197] In some embodiments, the power supply module can generate a true random number according to a sensor in the AC environment. There is no limitation on the number of digits of the true random number. Exemplarily, the number of digits of the true random number can be 32 bits or other numbers of digits.

[0198] In the embodiments of the present disclosure, the random number sent by the power supply module to the control module can be in plaintext or ciphertext.

[0199] If the random number is in ciphertext, a pre-set static password can be used to encrypt the random number sent by the power supply module to the control module. For example, the serial number (Serial Number, SN) of the battery included in the power supply module or the serial number of the CPU of the processing module is used to encrypt the random number sent by the power supply module to the control module. If the SN of the battery is used to encrypt the random number, the SN of the battery can be stored in the memory of the power supply module in advance. If the serial number of the CPU is used to encrypt the random number, the SN of the CPU is pre-stored in the memory of the power supply module.

[0200] In some embodiments, an encryption flag is added to the communication protocol, and the power supply module of the electronic device sends a flag indicating whether the random number is in plaintext or ciphertext to the control module, facilitating the control module to quickly identify the encryption status of the random number.

[0201] If the encryption flag indicates encryption, the random number sent by the power supply module to the control module is in ciphertext;

[0202] If the encryption flag indicates non-encryption, the random number sent by the power supply module to the control module is in plaintext.

[0203] By adding an encryption flag to the communication protocol, the communication between the control module and the power supply module of the electronic device becomes more flexible and convenient. Exemplarily, the encryption algorithm can be various pre-agreed algorithms, including but not limited to the Message-Digest Algorithm (MD5) and the Data Encryption Standard (DES).

[0204] In some embodiments, S403 may include:

[0205] If the ciphertext instruction is successfully decrypted, obtain the preset information in the decryption information;

[0206] Determine whether the decrypted control instruction is an expired instruction according to the preset information;

[0207] When the decrypted control instruction is not an expired instruction, perform the power supply operation according to the decrypted control instruction.

[0208] In some embodiments, preset information is introduced into the ciphertext instruction, and the preset information can be used to judge the status of the control instruction.

[0209] The preset information includes at least one of the following:

[0210] Random number;

[0211] The instruction generation time information of the control instruction;

[0212] The instruction generation sequence number of the control instruction.

[0213] In some embodiments, the preset information is a random number, and the power supply module and the control module can agree on the number of digits of the random number. If the number of digits of the obtained preset information is inconsistent with the agreed number of digits of the random number, it indicates that the ciphertext instruction is an expired instruction.

[0214] In some other embodiments, the preset information is the instruction generation time information of the control instruction. Exemplarily, the time information includes year, month, day, hour, minute, second, and millisecond. If the time difference between the generation time indicated by the generation time information and the current time is greater than a preset value, it indicates that the ciphertext instruction is an expired instruction.

[0215] In still some other embodiments, the preset information is a sequence number, and the sequence number is a unique identifier. Exemplarily, when the electronic device starts up, the sequence number starts counting from 0, and the life cycle of the sequence number is one startup of the electronic device. If the current sequence number is not continuous with the number in the previously executed ciphertext instruction, it indicates that the ciphertext instruction is an expired instruction.

[0216] By introducing preset information into the ciphertext instruction and determining whether the ciphertext instruction is an expired instruction according to the preset information, when the decrypted control instruction is not an expired instruction, the power supply operation is performed according to the decrypted control instruction, thereby further ensuring the safety of the power supply module of the electronic device.

[0217] In some embodiments, the expired instructions include at least one of the following:

[0218] Executed instruction;

[0219] The control instruction indicates a voided instruction.

[0220] In some embodiments, in order to accurately execute the control instruction, the power supply module of the electronic device needs to judge whether the control instruction has expired. The expired instructions include at least one of the following: executed instruction, the control instruction indicates a voided instruction.

[0221] Exemplarily, the executed instruction refers to all historical instructions executed by the power supply module after the current startup of the electronic device.
