[0053] To make the objectives, technical solutions and advantages of the present invention clearer, the following will clearly and completely describe the technical solutions in the present invention in conjunction with the drawings in the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art without creative efforts based on the embodiments in the present invention belong to the scope of protection of the present invention.

[0054] In the description of this embodiment, it should be noted that the terms "first", "second", and "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. Unless otherwise clearly specified and defined, the terms "connected" and "coupled" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium. For those of ordinary skill in the art, the specific meanings of the above terms in this embodiment can be understood according to specific circumstances.

[0055] The trend of diversification within the data platform is becoming increasingly prominent, and each platform is constantly exerting efforts to continuously provide various products for users in the data center to choose from. The different CPU characteristics of each platform limit the development of compatibility between different platforms, and the research and development of corresponding products are accompanied by a large amount of investment in terms of time, manpower, and money of the long-cycle R & D and testing teams.

[0056] Since DC-SCM is connected to the motherboard through a 4C+ connector with 168 pins (i.e., pins) defined in the OCP NIC 3.0 (Open Compute Project Network Interface Controller, version 3.0 of the network interface controller under the open source computing project) specification, the 168 pins of the 4C+ connector are assigned pins and signal definitions in the specification. When the 4C+ connectors used on the motherboards of different platform products simultaneously follow the standard DC-SCM specification, the DC-SCM module can be replaced and used on different motherboards, greatly improving the R & D efficiency. Therefore, DC-SCM emerged as the times require because it can effectively meet the security management requirements of a variety of different platforms and adapt to the needs of different platform product iterations.

[0057] In the prior art, the power required for each module inside the DC-SCM specification comes from the power supply pins of the 4C+ connector. When in use, the user needs to use the DC-SCM together with the motherboard power supply module so that the motherboard power supply module can provide the power required for the normal operation of the DC-SCM through the power supply pins of the 4C+ connector.

[0058] However, since a standard motherboard contains a CPU, memory, CPLD, power supply, and other peripheral circuits at the same time, it is large in size and high in cost, and is not convenient for mobile transportation. When only performing simple functions such as hardware signal or function testing on the DC-SCM single board, it still needs to be powered by the motherboard, resulting in a high power supply cost for the DC-SCM and a low utilization rate of the board card.

[0059] In view of the above problems, this embodiment provides a power supply device for a data center security control module (DC-SCM). A portable power module with a smaller size is used inside the device to supply power to the DC-SCM module, so that the standard DC-SCM no longer depends on the motherboard for power supply. This enables the DC-SCM to perform simple functions such as hardware signal testing or functional testing independently of the motherboard, achieving the reduction of power supply costs while increasing the applicable range of the DC-SCM board.

[0060] The following will describe in conjunction with Figure 1 the power supply device of the data center security control module in this embodiment. This device is applicable to scenarios for implementing simple functions of the DC-SCM, such as development and testing scenarios.

[0061] The device includes a connector assembly, a switch module 130, and a power module 140; the connector assembly includes a first connector 110 and a second connector 120;

[0062] It should be noted that the connector assembly, the switch module 130, and the power module 140 are all devices for implementing simple functions, with advantages such as simple implementation, small size, and low cost. Correspondingly, the combined power supply device also has the advantages of simple implementation, small size, and low cost.

[0063] Among them, the connector assembly is a device for implementing a simple connection function, which is used to establish a connection channel between each module inside the power supply device and the external DC-SCM and the external power supply, so as to effectively supply power to the DC-SCM.

[0064] The first connector 110 includes a connector that is the same as or adapted to the connector inside the data center security control module DC-SCM. Exemplarily, the first connector 110 is the same as the connector inside the DC-SCM, both being standard 4C+ connectors, and the signal distribution and signal definition of each pin in the first connector 110 follow the signal definition in the DC-SCM specification.

[0065] The first connector 110 can supply power to the DC-SCM through its internal power supply pins. Exemplarily, the first connector 110 supplies power to the DC-SCM through its internal power supply pins including OA1, OA2, OB1, and OB2.

[0066] The second connector 120 includes a power connector, which is used to connect to an external power supply to receive the input power of the external power supply, so that the power supply device can directly supply the total power input to the connector assembly, the switch module 130, and other modules inside the power supply device, as well as the DC-SCM connected to the power supply device.

[0067] The switch module 130 is a switch that can implement simple logic, which may include one or more groups of logic switches, and can be specifically set according to actual requirements.

[0068] The power supply module 140 can be constructed and generated based on a processor, a chip, etc. for implementing simple power control logic.

[0069] The first connector 110 is respectively connected to the data center security control module, the power supply module 140, and the switch module 130; the second connector 120 is respectively connected to an external power supply and the switch module 130;

[0070] As Figure 1 shown, the first connector 110 is electrically connected to the data center security control module, electrically connected to the power supply module 140, and electrically connected to the switch module 130; the second connector 120 is electrically connected to the power supply module 140; and the second connector 120 is also electrically connected to an external power supply and electrically connected to the switch module 130; the switch module 130 is electrically connected to the power supply module 140. Thus, a communication channel can be established among the internal modules of the power supply device, and a communication channel can be established between the internal modules of the power supply device and the external DC-SCM and the external power supply, thereby ensuring information interaction among the internal modules of the power supply device and among the external modules to achieve effective power supply to the DC-SCM.

[0071] The power supply module 140 is used to supply power to the switch module 130 according to the power supply signal transmitted by the external power supply;

[0072] The switch module 130 is used to monitor the data center security control module, the power supply module 140, and the external power supply, and generate a control signal according to the monitoring result;

[0073] The power supply module 140 is also used to supply power to the data center security control module according to the control signal and the power supply signal.

[0074] Optionally, when the power supply device is powered on, to avoid damage to the DC-SCM caused by direct power-on, after the power module 140 is set to be connected to the external input power supply, it first pauses to provide the power supply output to the standard 4C+ connector (i.e., the first connector 110); instead, it first converts the power supply signal transmitted by the external power supply into the power required for the operation of the switch module 130 to supply the power required for the operation of the switch module 130, and then the switch module 130 monitors the data center security control module through the first connector 110 to obtain the status of the data center security control module in real time, monitors the power module 140 through the communication channel directly connected to the power module 140 to obtain the status of the power module 140 in real time, and monitors the external power supply through the second connector 120 to obtain the status of the external power supply in real time;

[0075] Then, the switch module 130 makes decisions on the status of the data center security control module, the status of the power module 140, and the status of the external power supply to generate corresponding control signals, and transmits the control signals to the power module 140 through the communication channel directly connected to the power module 140 to control whether to turn on the power supply path to the DC-SCM after the power module 140 is connected to the external power supply.

[0076] It should be noted that the specific monitoring content of the switch module 130 can be determined according to the power supply requirements of the DC-SCM. Exemplarily, the switch module 130 needs to monitor whether the DC-SCM is installed in place, monitor whether there is an external power supply connected to the second connector 120 (i.e., whether the external power supply is in place) and whether the connected external power supply is working properly (i.e., whether the PWR_OK signal of the external power supply is normal), and monitor whether the status of the power module 140 is abnormal during operation, etc. This embodiment does not make specific limitations on this.

[0077] It should be noted that the control signals corresponding to different monitoring results are different, and different control signals correspond to different power supply decisions.

[0078] Optionally, when the power module 140 receives the control signal transmitted by the switch module 130, it supplies power to the data center security control module in combination with the power supply decision corresponding to the control signal and the power supply signal to ensure that a stable and reliable power supply is provided to the data center security control module.

[0079] The power supply device of the data center security control module provided in this embodiment can monitor the DC-SCM, power supply module 140, and external power supply by setting a simple and portable power supply device for the data center security control module DC-SCM. According to the monitoring results and the power supply signal provided by the external power supply, it can supply power to the DC-SCM stably and reliably. It can supply power to the DC-SCM independently of the main board power supply module supporting the DC-SCM, thereby reducing the power supply cost of the DC-SCM while increasing the applicable range of the DC-SCM.

[0080] In some embodiments, the control signal includes a first signal or a second signal, and the level of the first signal is greater than the level of the second signal;

[0081] The switch module 130 is specifically configured to:

[0082] Output the first signal when it is determined that the monitoring result meets the power supply condition;

[0083] Output the second signal when it is determined that the monitoring result does not meet the power supply condition.

[0084] Among them, the first signal and the second signal can be determined according to the actual circuit design of the power supply device. The first signal is an enabling signal with a high level, and the second signal is a suppressing signal with a low level. The level of the first signal is significantly higher than the level of the second signal. Exemplarily, the first signal is a signal with a level of 1, and the second signal is a signal with a level of 0.

[0085] The power supply condition is a limiting condition for supplying power to the DC-SCM, and it can be specifically configured according to the power supply requirements of the DC-SCM.

[0086] Optionally, when the switch module 130 obtains the monitoring result, it needs to compare the status of each module in the monitoring result with the corresponding configured status of each module in the power supply condition. When the status of each module meets the configured status, it indicates that the monitoring result meets the power supply condition. At this time, a high-level enabling signal (i.e., the first signal) can be output to the power supply module 140; when any one or more of the statuses of each module do not meet the configured status, it indicates that the monitoring result does not meet the power supply condition. At this time, a low-level suppressing signal (i.e., the second signal) can be output to the power supply module 140, so that the power supply module 140 can supply power to the data center security control module adaptively according to the different control signals output by the switch module 130 to ensure the reliability, stability, and security of the power supply.

[0087] In some embodiments, the power supply conditions include that all states among the in-position state of the data center security control module, the power supply state of the external power supply, the in-position state of the external power supply, and the operating state of the power supply module 140 are in normal states.

[0088] As Figure 2 and Figure 3 shown, when the external power supply works to supply power to the power supply device, the power supply module 140 receives the power supply signal input by the external power supply, first converts the power supply signal into the power required for the normal operation of the switch module 130. After the power of the switch module 130 is stable and starts to work, it monitors the state of the DC-SCM in-position PRSNT signal in real time, that is, monitors the PRSNT signal transmitted by the DC-SCM through the first connector 110; when it is monitored that the level state of the PRSNT signal of the DC-SCM is less than or equal to the first level value, that is, the level state of the PRSNT is low level, it is determined that the in-position state of the DC-SCM is in a normal state (that is, it is normally connected to the first connector 110).

[0089] When it is monitored that the level state of the PRSNT signal of the DC-SCM is greater than or equal to the second level value, that is, the level state of the PRSNT is high level, it is determined that the in-position state of the DC-SCM is in an abnormal state (that is, it is abnormally connected to the first connector 110). Thus, it is determined that the monitoring result does not meet the power supply conditions, and a second signal is output to the power supply module 140 to control the power supply module 140 to stop supplying power to the DC-SCM. Among them, the first level value and the second level value can be set according to actual needs. For example, the first level value is 0 and the second level value is 1.

[0090] In addition to monitoring the in-position state of the DC-SCM board, the switch module 130 also needs to monitor the state of the external power supply connected to the second connector 120, including but not limited to the power supply state and the in-position state of the external power supply. Specifically, it monitors the power normal (abbreviation: PWR_OK) signal and the PRSNT signal transmitted by the external power supply. When it is monitored that the level states of the PWR_OK signal and the PRSNT signal are normal, it is determined that both the power supply state and the in-position state of the external power supply are normal; when it is monitored that the level state of the PWR_OK signal and / or the PRSNT signal is abnormal, it is determined that the power supply state and / or the in-position state of the external power supply is abnormal, and further it is determined that the input power state of the external power supply is unstable. Thus, it is determined that the monitoring result does not meet the power supply conditions, and a second signal is output to the power supply module 140 to control the power supply module 140 to stop supplying power to the DC-SCM.

[0091] Meanwhile, in order to ensure that the operation status of the power supply module 140 is normal and improve the reliability of the DC-SCM power supply, the switch module 130 also needs to synchronously monitor the operation status of the power supply module 140. Among them, the operation status includes but is not limited to the status of environmental parameters and the status of operation parameters. The environmental parameters include temperature, etc., and the operation parameters include input voltage, input current, output voltage, and output current, which can be specifically determined according to the power supply requirements of the DC-SCM, and this embodiment does not make specific limitations in this regard.

[0092] Exemplarily, the switch module 130 monitors whether target parameters such as the input voltage, output voltage, input current, output current, and temperature inside the power supply module 140 are within the normal parameter range. When it is monitored that all target parameters inside the power supply module 140 are normal, it is determined that the operation status of the power supply module 140 is the normal status; when it is monitored that any parameter inside the power supply module 140 is abnormal, it is determined that the operation status of the power supply module 140 is abnormal, and thus it is determined that the monitoring result does not meet the power supply condition, and a second signal is output to the power supply module 140 to control the power supply module 140 to stop powering the DC-SCM.

[0093] When and only when all states among the in-place status of the data center security control module, the power supply status of the external power supply, the in-place status of the external power supply, and the operation status of the power supply module 140 are in the normal state, it is thus determined that the monitoring result meets the power supply condition, and a valid high-level enable signal (i.e., the first signal) is output to the power supply module 140 to control the power supply module 140 to start powering the DC-SCM.

[0094] In this embodiment, by setting multiple power supply condition judgments inside the power supply device, it is possible to realize powering the DC-SCM independently of the main board, reduce the dependence of the standard DC-SCM on the main board power supply, and improve the stability and reliability of the power supply.

[0095] In some embodiments, the power supply module 140 is specifically configured to:

[0096] In the case of receiving the first signal, according to the power supply requirements of the data center security control module, convert the power supply signal into a target signal, and based on the target signal, power the data center security control module;

[0097] In the case where the power supply module 140 receives the second signal, stop powering the data center security control module and issue an alarm.

[0098] Among them, the target signal is a signal determined according to the power supply requirements of the data center security control module. Exemplarily, in the DC-SCM specification, it is defined that the DC-SCM requires an external 12V power supply input for normal operation. Correspondingly, the target signal is a 12V power signal.

[0099] Optionally, when the power supply module 140 receives the first signal, i.e., the high-level enable signal, the power supply module 140 converts the power supply signal according to the power supply requirements of the data center security control module to obtain the target signal required for the normal operation of the DC-SCM. And the power supply module 140 needs to stably output the target signal to the power supply pins (such as the four pins OA1, OA2, OB1, and OB2) on the first connector 110 to supply power to the DC-SCM connected to the first connector 110, facilitating the user to perform simple operations such as hardware testing or function verification using the DC-SCM.

[0100] When the power supply module 140 receives the second signal, i.e., the low-level inhibition signal, the power supply module 140 stops supplying power to the DC-SCM and issues an alarm to send the monitoring result to the front end and prompt the user that the power supply of the DC-SCM is abnormal.

[0101] In this embodiment, the power supply module 140 can simply and conveniently adaptively switch the power supply mode of the data center security control module through different signals, ensuring the effectiveness and stability of the power supply while improving the flexibility of the power supply.

[0102] In some embodiments, the power supply device further includes a control button;

[0103] The switch module 130 is connected to the control button;

[0104] The switch module 130 is further configured to:

[0105] When receiving the first power supply instruction transmitted by the control button, output the first signal to the power supply module 140; the first power supply instruction is used to indicate starting to supply power to the data center security control module;

[0106] When receiving the second power supply instruction transmitted by the control button, output the second signal to the power supply module 140; the second power supply instruction is used to indicate stopping to supply power to the data center security control module.

[0107] Optionally, a control button is further provided on the power supply device so that the user can issue different power supply instructions by controlling the control button to flexibly switch the power supply mode of the DC-SCM.

[0108] When the user needs to manually control the power supply device to supply power to the DC-SCM, the start button on the control button can be pressed or rotated to control the control button to generate the first power supply instruction and send the first power supply instruction to the switch module 130.

[0109] Thus, the switch module 130 can receive the first power supply instruction in real time, and when receiving the first power supply instruction, output a first signal to the power supply module 140, so that the power supply module 140 can supply power to the DC-SCM according to the power supply signal provided by the external power supply when receiving the first signal.

[0110] When the user needs to manually control the power supply device to stop supplying power to the DC-SCM, the stop button in the control button can be pressed or rotated to control the control button to generate a second power supply instruction and send the second power supply instruction to the switch module 130.

[0111] Thus, the switch module 130 can receive the second power supply instruction in real time, and when receiving the second power supply instruction, output a second signal to the power supply module 140, so that the power supply module 140 stops supplying power to the DC-SCM when receiving the second signal.

[0112] In this embodiment, a control button is provided in the power supply device, which facilitates the user to control the state of the control button, that is, the power supply mode of the data center security control module can be simply and conveniently adaptively switched, further improving the flexibility of power supply.

[0113] In some embodiments, the power supply device further includes a test module 150;

[0114] The test module 150 is respectively connected to the first connector 110 and the power supply module 140;

[0115] The power supply module 140 is further configured to supply power to the test module 150 according to the power supply signal;

[0116] The test module 150 is configured to test and / or perform a function verification on the data center security control module based on the test instruction and / or the function verification instruction when receiving the test instruction and / or the function verification instruction.

[0117] Among them, the test module 150 can implement the test and / or function verification of the data center security control module. The test module 150 is used to connect other pins on the first connector 110 except the power pins, and is connected to the on-board connector in the power supply device, facilitating the user to perform hardware testing and / or function verification.

[0118] Optionally, when the user needs to test and / or perform a function verification on the DC-SCM, a test instruction and / or a function verification instruction can be input into the test module 150.

[0119] Thus, when the test module 150 receives a test instruction and / or a function verification instruction, it can, through the first connector 110, test and / or verify the function of the data center security control module based on the test instruction and / or the function verification instruction.

[0120] In this embodiment, by providing the test module 150 in the power supply device, the DC-SCM can be powered and tested independently of the main board, effectively solving the problem of high cost caused by the need to always power the DC-SCM with the main board when separately testing the DC-SCM or developing the functions of the DC-SCM, and the inability to work independently of the main board.

[0121] The power supply method provided by the present invention based on the data center security control module will be described below. The power supply method based on the data center security control module described below can be correspondingly referred to the power supply device based on the data center security control module described above.

[0122] As Figure 4 shown, a power supply method based on the data center security control module provided by this embodiment is applied to a power supply device, which includes a connector assembly, a switch module 130, and a power supply module 140; the connector assembly includes a first connector 110 and a second connector 120. For the specific structure of the power supply device, refer to Figure 1 , which will not be elaborated here.

[0123] The method includes the following steps:

[0124] Step 401, monitor the data center security control module, the power supply module, and the external power supply, and generate a control signal according to the monitoring results;

[0125] Step 402, receive the power supply signal transmitted by the external power supply, and supply power to the data center security control module according to the control signal and the power supply signal.

[0126] Optionally, when the power supply device is powered on, to avoid direct power-on damage to the DC-SCM, after the power supply module is set to be connected to the external input power supply, it first pauses to provide the power supply output to the standard 4C+ connector (the first connector); instead, it first converts the power supply signal transmitted by the external power supply into the power required for the switch module to work, to provide the power required for the switch module to work. Then, the switch module monitors the data center security control module through the first connector to obtain the status of the data center security control module in real time, monitors the power supply module through the communication channel directly connected to the power supply module to obtain the status of the power supply module in real time, and monitors the external power supply through the second connector to obtain the status of the external power supply in real time;

[0127] Then, the switch module generates corresponding control signals according to the status of the data center security control module, the status of the power supply module, and the status of the external power supply, and transmits the control signals to the power supply module through a communication channel directly connected to the power supply module to control whether the power supply module after connecting the external power supply is turned on to supply power to the DC-SCM.

[0128] It should be noted that the specific monitoring content of the switch module can be determined according to the power supply requirements of the DC-SCM module. Exemplarily, the switch module needs to monitor whether the DC-SCM module is installed in place, monitor whether the second connector is connected to an external power supply (i.e., whether the external power supply is in place), and whether the connected external power supply is working properly (i.e., whether the PWR_OK signal of the external power supply is normal), and monitor whether the status of the power supply module during operation is abnormal, etc. This embodiment does not make specific limitations on this.

[0129] It should be noted that different control signals correspond to different monitoring results, and different control signals correspond to different power supply decisions.

[0130] Optionally, when the power supply module receives the control signal transmitted by the switch module, it combines the power supply decision corresponding to the control signal and the power supply signal to supply power to the data center security control module to ensure a stable and reliable power supply for the data center security control module.

[0131] The power supply method based on the data center security control module provided in this embodiment sets up a simple and portable power supply device for the data center security control module DC-SCM. So that when the DC-SCM needs to implement simple functions, the power supply device can monitor the DC-SCM, the power supply module, and the external power supply, and supply power to the DC-SCM stably and reliably according to the monitoring results and the power supply signal provided by the external power supply. It can supply power to the DC-SCM independently of the motherboard power supply module supporting the DC-SCM, thereby reducing the power supply cost of the DC-SCM while increasing the applicable range of the DC-SCM.

[0132] In some embodiments, the control signal includes a first signal or a second signal, and the level of the first signal is greater than the level of the second signal;

[0133] Generating the control signal according to the monitoring results includes:

[0134] When it is determined according to the monitoring results that all states among the in-place state of the data center security control module, the power supply state of the external power supply, the in-place state of the external power supply, and the operating state of the power supply module are in normal states, the first signal is generated;

[0135] When, based on the monitoring results, it is determined that one or more of the in-position state of the data center security control module, the power supply state of the external power supply, the in-position state of the external power supply, and the operating state of the power supply module are in an abnormal state, the second signal is generated.

[0136] As Figure 3 shown, when the external power supply supplies power to the power supply device, the power supply module receives the power supply signal input by the external power supply, first converts the power supply signal into the power required for the normal operation of the switching module, and when the power supply of the switching module is stable and starts to work, it monitors all of the in-position state of the DC-SCM, the power supply state of the external power supply, the in-position state of the external power supply, and the operating state of the power supply module in real time;

[0137] When and only when all of the in-position state of the data center security control module, the power supply state of the external power supply, the in-position state of the external power supply, and the operating state of the power supply module are in a normal state, it is determined that the monitoring results meet the power supply conditions, and a valid high-level enable signal (i.e., the first signal) is output to the power supply module to control the power supply module to start supplying power to the DC-SCM.

[0138] When one or more of the in-position state of the data center security control module, the power supply state of the external power supply, the in-position state of the external power supply, and the operating state of the power supply module are in an abnormal state, it is determined that the monitoring results do not meet the power supply conditions, and a second signal is output to the power supply module to control the power supply module to stop supplying power to the DC-SCM.

[0139] In this embodiment, through multiple power supply condition judgments, it is possible to supply power to the DC-SCM independently of the main board, reduce the dependence of the standard DC-SCM on the main board power supply, and improve the stability and reliability of the power supply.

[0140] In some embodiments, the in-position state of the data center security control module is determined based on the following steps:

[0141] When, based on the monitoring results, it is determined that the level of the in-position signal of the data center security control module is less than or equal to the first level value, it is determined that the in-position state of the data center security control module is in a normal state;

[0142] When, based on the monitoring results, it is determined that the level of the in-position signal of the data center security control module is greater than or equal to the second level value, it is determined that the in-position state of the data center security control module is in an abnormal state;

[0143] Wherein, the first level value is less than the second level value.

[0144] Among them, the first level value and the second level value can be set according to actual requirements. For example, the first level value is 0 and the second level value is 1.

[0145] The presence state of the data center security control module (DC-SCM) is determined based on the state of the presence PRSNT signal.

[0146] Optionally, the switch module in the power supply device monitors the PRSNT signal transmitted by the DC-SCM through the first connector in real time. When it monitors that the level state of the PRSNT signal of the DC-SCM is less than or equal to the first level value, that is, the level state of the PRSNT is low level, it determines that the presence state of the DC-SCM is the normal state (i.e., normally connected to the first connector). When it monitors that the level state of the PRSNT signal of the DC-SCM is greater than or equal to the second level value, that is, the level state of the PRSNT is high level, it determines that the presence state of the DC-SCM is the abnormal state (i.e., abnormally connected to the first connector).

[0147] Similarly, when the switch module monitors the state of the external power supply connected to the second connector, it can also refer to the above monitoring steps for the DC-SCM.

[0148] Optionally, the switch module monitors the power supply normal (abbreviated as PWR_OK) signal and the PRSNT signal transmitted by the external power supply. When it monitors that the level states of the PWR_OK signal and the PRSNT signal are normal, it determines that both the power supply state and the presence state of the external power supply are normal; when it monitors that the level state of the PWR_OK signal and / or the PRSNT signal is abnormal, it determines that the power supply state or the presence state of the external power supply is abnormal.

[0149] In this embodiment, the switch module can conveniently and accurately obtain the state information of each module by collecting the signals transmitted by each module, and further realize the convenient and accurate control of the DC-SCM.

[0150] In some embodiments, the operating state of the power module is determined based on the following steps:

[0151] Based on the monitoring results, when it is determined that all the target parameters inside the power module are within the normal parameter range, it is determined that the operating state of the power module is the normal state; the target parameters include environmental parameters and operating parameters, the environmental parameters include temperature parameters, and the operating parameters include input voltage, input current, output voltage, and output current.

[0152] Based on the monitoring results, when it is determined that one or more of the target parameters inside the power module are not within the normal parameter range, it is determined that the operating state of the power module is the abnormal state.

[0153] Optionally, in order to ensure that the operation state of the power supply module is normal and improve the reliability of the DC-SCM power supply, the switching module also needs to synchronously monitor the operation state of the power supply module. Among them, the operation state includes but is not limited to the state of environmental parameters and the state of operation parameters. The environmental parameters include temperature, etc., and the operation parameters include input voltage, input current, output voltage, and output current, which can be specifically determined according to the power supply requirements of the DC-SCM, and this embodiment does not make specific limitations on this.

[0154] Optionally, the switching module monitors whether target parameters such as the input voltage, output voltage, input current, output current, and temperature inside the power supply module are within the normal parameter range. When it is monitored that all the target parameters inside the power supply module are normal, it is determined that the operation state of the power supply module is the normal state; when it is monitored that any one of the parameters inside the power supply module is abnormal, it is determined that the operation state of the power supply module is abnormal, and thus it is determined that the monitoring result does not meet the power supply condition, and a second signal is output to the power supply module to control the power supply module to stop powering the DC-SCM.

[0155] In this embodiment, through multiple power supply condition judgments, it is possible to realize powering the DC-SCM independently of the main board, reduce the dependence of the standard DC-SCM on the main board power supply, and improve the stability and reliability of the power supply.
