It can be understood by those skilled in the art that Figure 1 The structure shown is only for illustration and does not limit the structure of the above-mentioned computer device.

[0034] The memory 104 can be used to store computer programs, for example, software programs and modules of application software, such as the computer program corresponding to the method for obtaining device information in the embodiment of the present application. The processor 102 executes various functional applications and data processing by running the computer program stored in the memory 104, that is, to implement the above method. The memory 104 may include a high-speed random access memory, and may also include a non-volatile memory, such as one or more magnetic storage devices, flash memory, or other non-volatile solid-state memory. In some instances, the memory 104 may further include a memory remotely arranged relative to the processor 102, and these remote memories may be connected to the mobile terminal via a network.

[0036] In this embodiment, a method for accessing a baseboard management controller running on the mobile terminal is provided. Figure 2 is a flow chart of a method for accessing a baseboard management controller according to an embodiment of the present application, the method being applied to a server, such as Figure 2 As shown, the process includes the following steps:

[0037] Step S202: receiving access data from a terminal device through a power line, wherein the access data is used to access a baseboard management controller of a server.

[0038] As an optional embodiment of the present application, the server receives access data from the terminal device via the power line, and a power line carrier communication module interface can be added through the input and output board of the server. The power line carrier communication module interface has a hot-swap function for the power line carrier communication module.

[0039] According to the above steps, the medium for data transmission is the power line. Data transmission via the power line can improve the stability of data access and reduce dependence on the external environment.

[0040] Step S204: sending the access data to the baseboard management controller of the server.

[0041] As an optional embodiment of the present application, the input and output board of the server has a corresponding communication link with the baseboard management controller of the server. Each server includes a power carrier communication module and a baseboard management controller.

[0042] The method provided by the present application is highly versatile and can be applied to any server system in which the status of the server is monitored by a baseboard management controller. By introducing this communication method, the user can not only power the baseboard management controller and the server through wires, but also remove the dependence of the baseboard management controller on the network, so that as long as the baseboard management controller is powered on, the user can access the baseboard management controller in any environment, which greatly broadens the use scenarios of the baseboard management controller and can fully realize uninterrupted monitoring of the server.

[0043] Compared with the method of accessing the baseboard management controller of the server only through the network, the method provided by the present application has the following advantages:

[0044] 1. Currently, servers have high power requirements for high performance and good heat dissipation, so they are mostly placed in places with sufficient power, complete power grid infrastructure, and high signal stability;

[0045] 2. It can be accessed in the same power grid environment without the need to prepare separate signal lines;

[0046] 3. Add a communication method between terminal equipment and baseboard management controller to enhance the diversity and robustness of baseboard management controller monitoring.

[0047] Through the above steps, since the server receives access data from the power line carrier communication chip of the terminal device through the power line, and demodulates the access data through the power line carrier communication module of the server, the demodulated access data is sent to the baseboard management controller of the server. Therefore, the problem of the single method of accessing the baseboard management controller of the server only through the network in the related art can be solved, thereby achieving the effect of improving the diversity and robustness of server access.

[0048] The execution subject of the above steps may be a server, but is not limited thereto.

[0049] According to an optional embodiment of the present application, the access data is obtained by coupling the original access data sent by the terminal device to the power line through a power line carrier communication chip of the terminal device via a high-frequency transformer.

[0050] The original access data signal is generally several hundred KHz, and the grid frequency is 50Hz. The coupling function of the high-frequency transformer is used to load the original access data signal to the power line. The high-frequency transformer is a power transformer with an operating frequency exceeding the medium frequency (10kHz). It is mainly used as a high-frequency switching power supply transformer in a high-frequency switching power supply. It is also used as a high-frequency inverter power supply transformer in a high-frequency inverter power supply and a high-frequency inverter welding machine. According to the operating frequency, it can be divided into several grades: 10KHz-50KHz, 50KHz-100KHz, 100KHz~500KHz, 500KHz~1MHz, and above 10MHz. In this embodiment, a high-frequency transformer with a frequency in the range of 100KHz~500KHz can be selected.

[0051] It should be noted that before the original access data signal is loaded onto the power line using the coupling function of the high-frequency transformer, since the original access data signal is a digital signal, the original access data signal needs to be converted from a digital signal to an analog signal.

[0052] In the process of power line carrier communication, the transmitted data needs to be modulated before it can be transmitted, that is, the above-mentioned terminal device needs to modulate the access data. Among them, modulation is the process of processing the information of the signal source and adding it to the carrier to make it suitable for channel transmission. It is a technology that makes the carrier change with the signal. Generally speaking, the information of the signal source contains a DC component and a frequency component with a lower frequency, which is called a baseband signal. The baseband signal is often not used as a transmission signal, so the baseband signal must be converted into a signal with a very high frequency relative to the baseband frequency to be suitable for channel transmission. This signal is called a modulated signal, and the baseband signal is called a modulated signal. Modulation is achieved by changing the amplitude, phase or frequency of the high-frequency carrier, that is, the carrier signal of the message, so that it changes with the change of the baseband signal amplitude. After the terminal device loads the modulated signal onto the power line, the carrier communication module of the server can identify the identification information (identity identification number) of the terminal device, and the corresponding carrier module begins to demodulate the data and sends the demodulated data to the baseboard management controller.

[0053] Since the data sent by the terminal device is modulated data, it is necessary to demodulate the data. Specifically, sending the access data to the baseboard management controller of the server can be achieved by the following method: demodulating the access data through the power carrier communication module of the server to obtain demodulated access data; sending the demodulated access data to the baseboard management controller of the server.

[0054] Demodulation is the process of recovering a message from a modulated signal that carries information. In various information transmission or processing systems, the transmitter modulates the carrier with the message to be transmitted to generate a signal carrying the message. The receiver must recover the transmitted message before it can be used, which is demodulation. Demodulation is the inverse process of modulation. Different modulation methods have different demodulation methods. Corresponding to the classification of modulation, demodulation can be divided into sine wave demodulation and pulse wave demodulation. Sine wave demodulation can also be divided into amplitude demodulation, frequency demodulation and phase demodulation. In addition, there are some variants such as single sideband signal demodulation and residual sideband signal demodulation. Similarly, pulse wave demodulation can also be divided into pulse amplitude demodulation, pulse phase demodulation, pulse width demodulation and pulse code demodulation. Multiple modulations need to be equipped with multiple demodulations. Among them, the power carrier communication module of the server has the function of demodulating and processing the access data. Therefore, the data received by the baseboard management controller of the server is the data demodulated by the power carrier communication module of the server.

[0055] As an optional embodiment of the present application, the access data is demodulated and processed by the power carrier communication module of the server, including the following steps: identifying the identification information of the terminal device; determining the power carrier communication module of the server corresponding to the terminal device based on the identification information, and using the power carrier communication module of the server to demodulate the access data.

[0056] In some optional embodiments of the present application, the terminal device includes a first terminal device and multiple second terminal devices, wherein the first terminal device is used to control the multiple second terminal devices; each of the multiple second terminal devices is connected to multiple servers; the first terminal device controls any one of the multiple second terminal devices to couple access data to the power line through a high-frequency transformer.

[0057] As an optional embodiment of the present application, each terminal device is connected to multiple servers. As the number of server devices connected to the same terminal device increases, the load increases, the impedance changes, and the number of loads is limited. Therefore, the embodiment of the present application introduces the concept of a super terminal, that is, a terminal that can control multiple terminal devices at the same time is a super terminal, wherein each of the multiple terminal devices can access multiple servers; that is, a super terminal controls multiple terminal devices at the same time, and each terminal device is connected to multiple server devices, and each server device has a carrier module and a baseboard management controller module, forming a tree structure, thereby forming a link from the user end to the server end. The framework diagram of the baseboard management controller access system is shown in the figure below. Figure 3 As shown, in Figure 3In the embodiment, a super terminal controls multiple terminal devices, each terminal device has a carrier module, and each terminal device is connected to multiple servers. It should be noted that each server has a carrier module and a baseboard management controller module.

[0058] Among them, the carrier module can be a power line carrier communication module, also known as a single-phase power line communication modem, which uses the power grid to transmit data.

[0059] In some other optional embodiments of the present application, each of the multiple second terminal devices includes a power line carrier communication module; each server includes at least a power line carrier communication module and a baseboard management controller.

[0060] In an optional embodiment, after sending the access data to the baseboard management controller of the server, it is also necessary to: execute the instructions contained in the access data and generate a log during the execution of the instructions, wherein the log is used to record the operation information of the baseboard management controller; and send the log to the terminal device.

[0061] As another optional embodiment of the present application, the baseboard management controller implements processing and response to access data, that is, after receiving the access data sent by the terminal device, the baseboard management controller executes the instructions contained in the access data, wherein the instructions are, for example, commands to power on and off the server. While executing the access data, the baseboard management controller also has the function of recording log data.

[0062] As an optional embodiment of the present application, access data is generated, wherein the access data is used to access a baseboard management controller of a server; the access data is coupled to a power line through a high-frequency transformer by a power line carrier communication chip of a terminal device; and the access data is sent to the server via the power line.

[0063] The terminal device generates access data for accessing the baseboard management controller of the server. The power line carrier communication chip of the terminal device converts the access data from digital signals to analog signals and then couples the access data to the power line through a high-frequency transformer. The terminal device can access the baseboard management controller of the server through the power line.

[0064] The method provided by the present application is highly versatile and can be applied to any server system in which the status of the server is monitored by a baseboard management controller. By introducing this communication method, the user can not only power the baseboard management controller and the server through wires, but also remove the dependence of the baseboard management controller on the network, so that as long as the baseboard management controller is powered on, the user can access the baseboard management controller in any environment, which greatly broadens the use scenarios of the baseboard management controller and can fully realize uninterrupted monitoring of the server.

[0065] Through the description of the above implementation methods, those skilled in the art can clearly understand that the method according to the above embodiment can be implemented by means of software plus a necessary general hardware platform, and of course by hardware, but in many cases the former is a better implementation method. Based on this understanding, the technical solution of the present application, or the part that contributes to the prior art, can be embodied in the form of a software product, which is stored in a storage medium (such as ROM / RAM, magnetic disk, optical disk), and includes a number of instructions for a terminal device (which can be a mobile phone, computer, server, or network device, etc.) to execute the methods described in each embodiment of the present application.

[0083] 3. Add a communication method between terminal equipment and baseboard management controller to enhance the diversity and robustness of baseboard management controller monitoring.

[0084] Through the above device, since the server receives access data from the power line carrier communication chip of the terminal device through the power line, and demodulates the access data through the power line carrier communication module of the server, the demodulated access data is sent to the baseboard management controller of the server. Therefore, the problem of the single method of accessing the baseboard management controller of the server only through the network in the related art can be solved, thereby achieving the effect of improving the diversity and robustness of server access.
