Further, the controller is connected with the power supply module and used for controlling the on-off of the power supply module and controlling the power-on and power-off of the MXM display unit in a time control mode, and the MXM display unit is protected.

It should be noted that after the fault is reported to the upper computer, the operation state of the MXM display unit can be directly observed conveniently, and an alarm is generated when the MXM display unit fails, so that a controller can handle the fault in time. The data and time for reporting to the upper computer are not limited to the above manner, and for example, the read operation parameters and the alarm signal may be reported to the upper computer at regular time, and when the operation state of the MXM display unit is the fault state, the fault state may be reported to the upper computer immediately.
Based on the rear plug-in external connector, the controller is also used for receiving a control command issued by the upper computer through the rear plug-in external connector and executing legal action. The control command can be generated and issued at any time, for example, when the MXM display unit is in a normal running state, the MXM display unit is required to stop working, a power-off command is issued to the controller through the upper computer, and the controller is electrically connected with the power supply module, so that the power supply module is controlled to be powered off after the controller receives the power-off command; and if the MXM display unit needs to be reset when the MXM display unit is in a fault state, issuing a reset instruction to the controller through the upper computer, and controlling the MXM display unit to reset through the SMBus management bus based on the MXM connector after the controller receives the reset instruction.

The independent monitoring device of the embodiment does not depend on a processor, an MXM display unit, a BIOS or an operating system of a computer to work, and has strong independence; and monitoring information to MXM display element is abundant, adopts the mode that inside data and external data combine, effectively improves the reliability of monitoring process.
In another embodiment, there is also provided an independent monitoring method of an MXM display unit for monitoring an operation state of the MXM display unit, the independent monitoring method of the MXM display unit being implemented in the controller, comprising the steps of:
and step S1, calling a preset SMBus bus protocol corresponding to the basic information according to the basic information of the MXM display unit to establish SMBus bus communication with the MXM display unit, wherein the basic information comprises manufacturer, model and serial number.
And S2, receiving the operation parameters and the alarm signals uploaded by the MXM display unit, receiving the temperature and the humidity of the peripheral environment of the MXM display unit fed back by the temperature and humidity sensor, and receiving the current and the voltage of the link where the MXM display unit is located fed back by the current/voltage sensor.
And step S3, judging whether the operation state of the MXM display unit is a normal working state or a fault state according to the alarm signal, the operation parameters, the temperature and the humidity and the current and voltage.
The independent monitoring method provided by the embodiment is adaptive to SMBus management bus protocols of MXM display units of different manufacturers, and is good in universality. The manufacturers which can be supported by the test comprise Nvidia, AMD and Jingjia micro, and the method is also suitable for supporting MXM display units of other manufacturers after the SMBus bus protocol is preloaded.
The alarm signal in this embodiment includes, but is not limited to, a voltage anomaly signal, an over-temperature signal, and an overload signal, and the operation parameter includes, but is not limited to, a display card GPU master frequency, a display memory occupancy rate, and a GPU usage rate. The fault conditions include: overcurrent of a link where the MXM display unit is located, overvoltage of a link where the MXM display unit is located, overtemperature of the MXM display unit, short circuit of the MXM display unit and disconnection of the MXM display unit.
How to judge whether the MXM display unit is in the fault state according to the operation parameters and the alarm signal can be realized based on the existing judgment logic and can also be a user-defined corresponding relation according to the requirement. For example, if the alarm signal comprises an over-temperature signal, judging that the MXM display unit is in an over-temperature fault state; if the MXM display unit does not output data to the controller within a certain time and the current/voltage sensor detects that no current exists in the link, judging that the MXM display unit is in a fault state and the fault state is that the MXM display unit is in an open circuit; if the MXM display unit does not output data to the controller within a certain time and the current/voltage sensor detects that the current in the link is suddenly increased, the MXM display unit is judged to be in a fault state, and the fault state is that the MXM display unit is short-circuited.
When the alarm signal and the external sensor data have feedback at the same time, comprehensive judgment is carried out by taking the alarm signal as a main part and the external sensor data as an auxiliary part, for example, if the alarm signal is an over-temperature signal and the temperature fed back by an external temperature and humidity sensor is normal, the operation state of the MXM display unit is judged to be a fault state and is the fault state of the MXM display unit over-temperature; when only the external sensor data has feedback, the operating state of the MXM display unit is directly determined to be a failure state, and the determination of the specific failure state is made with the external sensor data.
The fault state of each feedback in the monitoring process can only comprise one fault or a plurality of faults, and the method and the device are not limited to fault monitoring of the MXM display unit, and can also realize monitoring of the device, such as operation monitoring of various sensors, so as to ensure monitoring reliability.
To further enhance the detection control of the MXM display unit, in an embodiment, the method for independently monitoring the MXM display unit further includes:
reporting the read operation parameters of the MXM display unit to an upper computer through the rear-plug external connector, and reporting an alarm signal of the MXM display unit and the fault state to the upper computer when the operation state of the MXM display unit is judged to be the fault state; and receiving a control command issued by the upper computer through the rear plug-in external connector to execute legal action.
