TECHNICAL FIELD

[0001] The present application belongs to the technical field of communication, and particularly relates to a device communication method and device, an electronic device and a readable storage medium. BACKGROUND

[0002] With the rapid development of computer technology, servers are increasingly widely used in the Internet and daily work and life. In the running process of the server, a baseboard management controller (BMC) can be used to monitor and manage the server. When the baseboard management controller monitors and manages the server, communication between the terminal device and the baseboard management controller is needed to realize monitoring and debugging of the server. In a special server, a unique security card hardware can be installed. Due to the need for protection of the special server, the special server can strictly limit the communication function of the BMC connected thereto, for example, cannot connect to the Internet, cannot remotely operate the special server through the management page of the BMC, and the like. In addition, the room where the special server is located usually shields wireless signals to prevent wireless devices from communicating with the BMC.

[0003] In the related art, communication between the terminal device and the baseboard management controller of the special server is mainly realized by using a communication port.

[0082] The technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art belong to the scope of protection of the present application.

[0083] The terms "first", "second", and the like in the specification and claims of the present application are used to distinguish similar objects, and are not used to describe a specific order or sequence. It should be understood that the data used in this way can be exchanged under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described herein, and the objects distinguished by "first", "second", etc. are usually a category, and are not limited to the number of objects, for example, the first object can be one or more. In addition, "and / or" in the specification and claims indicates at least one of the connected objects, and the character " / ", generally indicates that the front and rear associated objects are in an "or" relationship.

[0084] The device communication method provided by the embodiments of the present application will be described in detail below with reference to the drawings, specific embodiments and application scenarios.

[0085] Referring to Figure 1 , Figure 1 A step flow chart of a device communication method provided by an embodiment of the present application is shown, as Figure 1 shown, specifically comprising the following steps:

[0086] Step 101, generating a noise signal based on a mainboard clock signal; the noise signal is used to interfere with the mainboard clock signal sent by a target device to a security card.

[0087] In the embodiments of the present application, the target device can be a baseboard management controller, the target device can be connected with a dedicated server and a security card, the security card can be used to monitor the communication activities between the target device and the dedicated server, and the security card can receive a mainboard clock signal and a data signal. The security card can interpret the data signal based on the clock signal. When the security card interprets the information corresponding to the data signal, the security card can prevent the target device from communicating with the dedicated server. Therefore, in order to realize the communication between the target device and the dedicated server, a noise signal can be generated, and since the frequency, amplitude, phase and other characteristics of the data signal are often changed, the noise signal corresponding to the mainboard clock signal can be generated based on the mainboard clock signal, and the noise signal can interfere with the mainboard clock signal when the target device sends the mainboard clock signal to the security card.

[0088] In step 102, the noise signal is sent to a target port of the security card; wherein the target port is used for the security card to monitor the running state of the target device.

[0089] In the embodiments of the present application, after the noise signal corresponding to the mainboard clock signal is obtained, the noise signal can be sent to the target port of the security card. The target port can be a receiving port of the security card for receiving the mainboard clock signal from the target device. The noise signal can be sent synchronously when the target device sends the mainboard clock signal to the security card. If the synchronous sending is not correctly performed during the sending process, the initial phase of the noise signal can be adaptively adjusted to achieve the effect of synchronous sending.

[0090] In step 103, a first signal is determined based on a first access instruction sent by a second terminal and the target device.

[0091] In the embodiments of the present application, the second terminal can be a terminal device directly controlled by a user, and the second terminal and the first terminal can be connected through a wireless communication module. The second terminal can send a first access instruction to the first terminal through the wireless communication module. The second terminal can first generate the first access instruction, and then send the first access instruction to the wireless communication module of the second terminal. The wireless communication module of the second terminal can encode the first access instruction and send the encoded signal, and the wireless communication module of the first terminal can receive the encoded signal and decode the signal, so as to obtain the first access instruction. The first terminal can access the related information in the target device according to the content of the first access instruction after obtaining the first access instruction. After obtaining the related information, the first terminal can encode the information, so as to obtain the first signal.

[0092] In step 104, the first signal is sent to the second terminal based on a preset wireless communication protocol and a preset transmission frequency.

[0093] In the embodiment of the present application, after obtaining the first signal, the wireless communication protocol and the transmission frequency used for communication between the first terminal and the second terminal can be preset, and then the first signal can be sent to the second terminal based on the preset wireless communication protocol and at the preset transmission frequency. After receiving the first signal, the wireless communication module of the second terminal can decode the first signal, so that the relevant information corresponding to the first access instruction can be obtained, thereby completing the communication between the first terminal and the second terminal.

[0094] In the embodiment of the present application, the noise signal is generated based on the mainboard clock signal; the noise signal is used to interfere with the clock signal sent by the target device to the security card; the noise signal is sent to the target port of the security card; the target port is used for the security card to monitor the running state of the target device; the first signal is determined based on the first access instruction sent by the second terminal and the target device; the first signal is sent to the second terminal based on the preset wireless communication protocol and the preset transmission frequency. The monitoring effect of the security card on the target device can be shielded, so that the remote access of the user to the target device can be realized, the communication process is simplified, and the time cost and the labor cost are saved.

[0095] As shown in Figure 2 , the method provided by the embodiment of the present application can include: Figure 2

[0096] Step 201, obtaining a first communication state of the security card; the first communication state includes a transceiving state and a receiving state.

[0097] In the embodiment of the present application, the security card can have two communication states, which are the transceiving state and the receiving state. In the transceiving state, the security card can receive external signals and also can send signals to the outside; in the receiving state, the security card can only receive external signals. Therefore, after the security card is powered on, the first communication state of the security card can be obtained. The security card can be loaded with a basic input output system (BIOS), and within a period of time after the security card is powered on, the basic input output system can be in a starting stage, at this time, the security card can be in the receiving state, and when the basic input output system is started, the security card can be in the transceiving state.

[0098] Step 202, in the case that the first communication state is the receiving state, generating a noise signal based on a mainboard clock signal.

[0099] ​In the embodiment of the present application, when the communication state of the security card is the receiving state, the communication bus of the security card can be in the free state, at this time, the noise signal can be generated by the first terminal according to the mainboard clock signal. The noise signal can be used to interfere with the mainboard clock signal received by the security card.

[0100] Specifically, in step 202, the following sub-steps can be included:

[0101] Sub-step 2021, obtaining the first phase, the first frequency and the first amplitude value of the mainboard clock signal.

[0102] In the embodiment of the present application, in order to generate the noise signal that can be used for interference, it is necessary to determine various information of the mainboard clock signal, including the first phase, the first frequency, the first amplitude value and the duty cycle, etc. The clock signal can usually be a square wave signal including only high level information and low level information, and in general cases, the duty cycle of the clock signal can be 50%, so the duty cycle of the mainboard clock signal can be defaulted here. Therefore, the information of the mainboard clock signal obtained can include the first phase, the first frequency and the first amplitude value. The first phase can be the initial phase of the mainboard clock signal, or the phase value at any time.

[0103] Sub-step 2022, inverting the first phase to obtain the second phase.

[0104] In the embodiment of the present application, in order to make the noise signal have the function of interfering with the clock signal, the first phase of the mainboard clock signal can be inverted to obtain the second phase. At the same time, the second phase and the first phase can be opposite numbers, that is, the sum of the second phase and the first phase can be 0.

[0105] Sub-step 2023, generating the noise signal based on the second phase, the first frequency and the first amplitude value.

[0106] In the embodiment of the present application, in the case where the second phase, the first frequency and the first amplitude value have been determined, the noise signal can be generated in combination with the defaulted duty cycle. The frequency, amplitude value and duty cycle of the noise signal are the same as those of the mainboard clock signal, and the phase is opposite, so the noise signal has the ability to interfere with the mainboard clock signal. It should be noted that in the case where the duty cycle of the mainboard clock signal is other values, the duty cycle of the noise signal can be set to be complementary to the duty cycle of the mainboard clock signal, that is, the sum of the duty cycle of the noise signal and the duty cycle of the mainboard clock signal is 1, at this time, the duty cycle of the mainboard clock signal can be included in the information used to generate the noise signal. In addition, a phase-locked loop can be used to stabilize the phase of the noise signal.

[0107] In the embodiment of the present application, Figure 3It is a general schematic diagram of phase-locked loop. The working principle of phase-locked loop is to detect the phase difference between the input signal and the output signal, and convert the detected phase difference signal into a voltage signal output through a phase detector, filter the voltage signal output through a low-pass filter to form a control voltage of a voltage-controlled oscillator, control the frequency of the oscillator output signal, and feedback the frequency and phase of the oscillator output signal to the phase detector through a feedback path. When the frequency of the output signal is proportional to the frequency of the input signal, the output voltage and the input voltage maintain a fixed phase difference value, so that the phase of the output voltage and the input voltage is locked.

[0108] In the embodiment of the present application, by acquiring the first phase, the first frequency and the first amplitude value of the mainboard clock signal, the first phase is inverted to obtain the second phase, and the noise signal opposite to the mainboard clock signal can be generated based on the second phase, the first frequency and the first amplitude value, and the interference performance of the noise signal is further improved.

[0109] In addition, step 202 can further include the following sub-steps:

[0110] Sub-step A1, in the case where the first communication state is the receiving state, acquiring the mainboard time.

[0111] In the embodiment of the present application, in the case where the first communication state of the security card is the receiving state, the mainboard time can also be acquired to determine the time information of the first terminal.

[0112] Sub-step A2, setting the security card time based on the mainboard time and a preset time length; wherein the difference between the security card time and the mainboard time is equal to the preset time length.

[0113] In the embodiment of the present application, a preset time length can be calibrated, and after the mainboard time is acquired, the security card time can be set according to the mainboard time and the preset time length, and the difference between the security card time and the mainboard time can be the preset time length. It should be noted that the security card time can be lagging compared to the mainboard time, that is, the time corresponding to the time indicated by the mainboard time after the time period corresponding to the preset time length can be the time indicated by the security card. For the time indicated by the mainboard time, the time indicated by the security card belongs to the "future time".

[0114] In the embodiment of the present application, by acquiring the mainboard time in the case where the first communication state is the receiving state, and setting the security card time based on the mainboard time and the preset time length, wherein the difference between the security card time and the mainboard time is equal to the preset time length, the security card can not generate a detection record, and the interference effect on the security card is further enhanced.

[0115] In the embodiments of the present application, the first communication state of the security card is acquired, the first communication state includes a transceiving state and a receiving state, and in the case that the first communication state is the receiving state, a noise signal is generated based on the mainboard clock signal. The noise signal can be generated when the security card is in the receiving state, thereby improving the availability of the noise signal.

[0116] In step 203, the noise signal is sent to a target port of the security card, and the target port is used to monitor the running state of the target device.

[0117] In the embodiments of the present application, the security card can be connected with the target device through the target port, so that the mainboard clock signal sent by the target device can be obtained. After the noise signal is acquired, the noise signal can be sent to the target port, so that the mainboard clock signal can be interfered, and then the security card receiving the mainboard clock signal can be interfered. The noise signal can be transmitted based on a phase-locked loop, that is, the noise signal transmitted by the phase-locked loop can continuously receive the signal of the communication bus slot of the security card during the loading and starting of the operating system in the starting process, and an inverted noise signal can be output at the same time, so as to ensure that the security card does not detect the signal of the transmission end of the BMC network port during the whole process. The transmission principle of the phase-locked loop controlled by the script is as follows:

[0118] Suppose the transfer function of the phase-locked loop is H(s), the noise power density of the input reference signal, that is, the security card signal, is N in , the noise power density of the pressure cavity oscillator V CO is N vco , the noise power density of the loop filter is N lp , and the crystal clock signal is N OSC . The output noise power density N out can be represented as:

[0119] N out = |H(jω)|2 × (N in + N vco + N lp +N OSC ) (Formula 1)

[0120] In formula 1, |H(jω)|2 is the square of the amplitude-frequency response of the transfer function of the phase-locked loop at the frequency ω.

[0121] Specifically, in step 203, the following sub-steps can be included:

[0122] Sub-step 2031, receiving the connection request instruction sent by the second terminal.

[0123] In the embodiments of the present application, the connection request instruction sent by the second terminal can be received before the noise signal is sent to the target port of the security card. The connection request instruction can represent the connection intention of the second terminal to the target device.

[0124] In response to the connection request instruction, connection information of the target device is sent to the second terminal based on the connection request instruction in substep 2032. The connection information is used for the second terminal to establish a connection with the target device.

[0125] In the embodiments of the present application, the first terminal can request the corresponding connection information of the target device in response to the connection request from the second terminal, wherein the connection information is used for the second terminal to establish a connection with the target device. After obtaining the connection information of the target device, the connection information can be sent to the second terminal.

[0126] In substep 2033, a connection information feedback signal sent by the second terminal is received. The connection information feedback signal is used to indicate the connection state of the second terminal and the target device.

[0127] In the embodiments of the present application, after receiving the connection information of the target device, the second terminal can establish a connection with the target device according to the connection information, and send a connection information feedback signal to the first terminal. The connection information feedback signal is used to indicate the connection state of the second terminal and the target device, i.e., whether the second terminal and the target device are successfully connected.

[0128] In substep 2034, the noise signal is sent to the target port of the security card when the connection information feedback signal indicates that the second terminal and the target device are successfully connected.

[0129] In the embodiments of the present application, when the connection information feedback signal indicates that the second terminal and the target device are successfully connected, the noise signal can be sent to the target port of the security card. The specific sending process can refer to the embodiments of step 203, which will not be described here.

[0130] In the embodiments of the present application, the connection information of the target device is sent to the second terminal based on the connection request instruction in response to the connection request instruction received by the second terminal, the connection information being used for the second terminal to establish a connection with the target device, the connection information feedback signal sent by the second terminal is received, the connection information feedback signal being used for indicating the connection state of the second terminal with the target device, and the noise signal is sent to the target port of the security card in the case that the connection information feedback signal indicates that the second terminal is successfully connected with the target device, so that whether an external device is connected with the target device can be confirmed before the noise signal is sent, and the power consumption of the first terminal can be saved.

[0131] In step 204, the first signal is determined based on the target device and the first access instruction sent by the second terminal.

[0132] In the embodiments of the present application, after the noise signal is sent to the target port of the security card, the first access instruction of the second terminal can be received, the access information corresponding to the first access instruction can be obtained from the target device based on the first access instruction, and the first signal can be generated based on the access information.

[0133] Specifically, in step 204, the following sub-steps can be included:

[0134] In sub-step 2041, the second signal sent by the second terminal is received and decoded to obtain the first access instruction, the second signal being obtained by encoding the first access instruction by the second terminal, and the second signal being sent by the second terminal based on the preset wireless communication protocol and the preset transmission frequency.

[0135] In the embodiments of the present application, the second terminal can generate the first access instruction, encode the first access instruction to obtain the second signal, and then send the second signal, the first terminal can receive the second signal and decode the second signal to obtain the first access instruction. Since the first terminal can preset the wireless communication protocol and the transmission and reception frequency of the signal, the second terminal can send the second signal according to the preset wireless communication protocol and the preset transmission frequency when sending the second signal.

[0136] In sub-step 2042, the first reply instruction sent by the target device corresponding to the first access instruction is determined.

[0137] In the embodiments of the present application, since the first terminal can be pre-connected with the target device, after obtaining the first access instruction, the first terminal can request the target device for information corresponding to the first access instruction, and the target device can respond to the request and send the first terminal a first reply instruction generated based on the information corresponding to the first access instruction.

[0138] In substep 2043, the first reply instruction is encoded to obtain the first signal.

[0139] In the embodiments of the present application, after obtaining the first reply instruction, the first reply instruction can be encoded based on a preset wireless communication protocol, so that the first signal can be obtained.

[0140] In the embodiments of the present application, the first access instruction is obtained by receiving and decoding the second signal sent by the second terminal, wherein the second signal is obtained by encoding the first access instruction by the second terminal; the second signal is sent by the second terminal based on a preset wireless communication protocol and a preset transmission frequency, and the first reply instruction corresponding to the first access instruction sent by the target device is encoded to obtain the first signal.

[0142] In substep B1, the second communication state of the target device is determined.

[0143] In the embodiments of the present application, the second communication state of the target device can be determined first. The second communication state can be the communication state of the target device with the second terminal, or the communication state of the target device with other external devices except the security card.

[0144] In substep B2, in the case that the second communication state indicates that the target device cannot communicate, the second phase is adjusted so that the second phase is opposite to the first phase, and the step of determining the second communication state of the target device is performed.

[0145] In the embodiments of the present application, when the target device cannot communicate with the external device, it indicates that the shielding of the security card does not take effect. At this time, the second phase of the noise signal can be adjusted so that the second phase is opposite to the first phase, and after adjusting the second phase, the second communication state of the target device is determined again.

[0146] Sub-step B3, in a case where the second communication state indicates that the target device is in normal communication, determining the first signal based on the first access instruction sent by the second terminal and the target device.

[0156] Optionally, in the embodiments of the present application, the preset wireless communication protocol includes a Bluetooth protocol, and / or the preset transmission frequency includes a terahertz frequency.
