FIG. 3 is a schematic diagram showing an example of a circuit of a power supply abnormality detecting unit in an abnormal state warning method according to an embodiment of the present invention.

The embodiments of the present invention will be described in more detail below with reference to the drawings and the reference numerals, which can be implemented by those skilled in the art after having studied this specification.

Referring to the first figure, a schematic flowchart of an operation of an abnormal state alerting method according to an embodiment of the present invention is shown. As shown in the first figure, the abnormal state alerting method of the present invention mainly includes steps S1, S10, S12, S20, S30, S32, S34, S36 and S38, which can provide a warning function when an abnormal state occurs in the system. At the same time, with reference to the second figure, a system diagram of an abnormal state warning method according to an embodiment of the present invention, wherein the system includes a central processing unit (CPU) U10 and a basic input/output system (BIOS). U12, memory unit U14, platform controller hub (PCH) U16, baseboard management controller (BMC) U18, at least three power supply units U20, abnormal state detection unit U22, multiple hard disks Hard Disk Drive (HDD) U24, a plurality of temperature sensing elements U26, a warning unit U28, and a display unit U30. In addition, the system may further include a fan (not shown) that enhances heat dissipation efficiency.

Specifically, the basic input/output system U12, the memory unit U14, and the platform control hub U16 of the system are electrically connected to the central processing unit U10, and the substrate management controller U18, the abnormal state detecting unit U22, and the hard disk drive U24 are It is electrically connected to the platform control hub U16. Further, the temperature sensing element U26, the warning unit U28, and the display unit U30 are electrically connected to the substrate management controller U18.

More specifically, each power supply unit U20 has a power distribution regulation function, and can independently supply power, and at the same time, generate a power supply notification signal PG when the output power is stable, and the abnormal state detecting unit U22 determines whether a power abnormal state occurs. For example, two or more power supply units U20 cannot supply normal power at the same time, and generate a power abnormality signal, and each temperature sensing component U26 can individually detect the temperature of the corresponding electrical component, such as central processing U10, memory unit U14, Platform control hub U16, base The board management controller U18, the power unit U20, the hard disk drive U24, the fan, and generates a temperature sensing signal.

First, the abnormal state warning method of the present invention starts from step S1, and proceeds to step S10. The substrate management controller U18 checks whether the abnormal state detecting unit U22 transmits a power abnormality signal, and transmits the power abnormality in the abnormal state detecting unit U22. In the case of signal, step S12 is executed to start the control alarm unit U28 to perform the power abnormality warning action, and return to step S1 after completing the power supply abnormality warning action, thereby notifying the operator that the power supply is abnormal, and it may be necessary to immediately start the standby power, or view the power. Each power unit U20 replaces the abnormal power unit U20. In addition, the display unit U30 can be driven to display preset warning texts, icons, images, and movies to further alert the operator.

The warning unit U28 may include a light emitting diode (LED) module and/or a buzzer, and the power abnormal warning action may include lighting the LED module to generate a flash or stabilize the light, starting the buzzer to sound a warning, and transmitting Newsletters, emails to remote monitors, or execute specific applications (APPs).

If the abnormal state detecting unit U22 does not transmit the power abnormality signal, the process proceeds to step S20, and the temperature sensing signal from each of the temperature sensing elements U26 is received by the substrate management controller U18. Preferably, the temperature sensing signal is converted into a temperature sensing signal and transmitted to the substrate management controller U18 by using a transmission interface (not shown), and the temperature sensing information is taken out by the substrate management controller U18. Temperature data, wherein the transmission interface can be implemented by a serial bus transfer wafer, such as an I2C chip.

Next, in step S30, it is determined whether or not a temperature abnormality has occurred based on the received temperature sensing signal or temperature data. If the temperature abnormality has not occurred, the process returns to step S1 and restarts, and if the abnormality occurs, the process proceeds to step S32. In step S32, a temperature abnormality warning message is generated by the substrate management controller U18, and transmitted to the platform control hub U16. Then, in step S34, the temperature abnormality warning message is transmitted via the central processing unit U10 and the memory unit U14. Send to the basic input and output system U12.

Then, the process proceeds to step S36, and the warning operation command is generated by the basic input/output system U12, and transmitted to the baseboard management controller U18 via the central processing unit U10 and the platform control hub U16, thereby starting the preset warning action of the warning unit U28. Finally, in step S38, the warning display command is generated by the basic input/output system U12, and transmitted to the substrate management controller U18 via the central processing unit U10 and the platform control hub U16, thereby driving the display unit U30 to display the corresponding temperature abnormality warning message, and returning Go to step S1 to repeat the above steps.

Specifically, the power supply abnormality detecting unit U22 determines whether to transmit the power abnormality signal in step S10, mainly according to whether the power supply abnormality occurs in two or more power supply units U20, such as the power supply voltage and the current shortage. Exceeding the critical upper limit value or the fluctuation range is too large and unstable, and the specific method is that the abnormality state detecting unit U22 receives the power supply notification signal PG from each power supply unit U20, and performs or logical processing so that there are two or two The above power supply notification signal PG represents a power supply abnormality signal when the power supply is abnormal. Taking three power supply units U20 as an example, and the signals A, B, and C respectively represent the power supply notification signals PG of the three power supply units U20, and the signal Y represents the power supply abnormality signal, the signal Y can be expressed by the following formula (A): Y =AB+BC+AC (A) and can be further reduced to the formula (B): Y=B(A+C)+AC (B)

Therefore, as shown in the circuit example of the power supply abnormality detecting unit U22 in the third figure, the power supply abnormality detecting unit U22 mainly includes two or two gates, two gates, and four logic gates, which are five logics of formula (A). There are still fewer gates to achieve optimal circuit design.

In addition, the baseboard management controller U18 can further receive a system event signal F that can affect the normal operation of the system on behalf of a particular system event occurring in the system, If the data of the memory is incorrectly accessed or overheated, the fan is not working properly, or the temperature of the battery, motherboard, or chassis is too high. At this time, the substrate management controller U18 can transmit the system event signal F to the basic input/output system U12 via the platform control hub U16 and the central processing unit U10. Then, the basic input/output system U12 is controlled via the central processing unit U10 and the platform control hub U16. The substrate management controller U18 drives the display unit U30 to display corresponding texts, illustrations, images, and movies regarding system events to alert the operator.

In particular, the system in the abnormal state alerting method of the present invention may further include a remote monitoring unit U32 located at the remote end and connected to the baseboard management controller U18 by using a network, such as a terminal, a server, or a system host, mainly The control of the baseboard management controller U18 receives the power supply abnormality message, the warning message, and the specific event message, thereby displaying, storing, or further analyzing and processing the necessary measures.

In summary, the main feature of the abnormal state alerting method of the present invention is that when a power abnormality, a temperature abnormality, and/or a specific system event occurs in the system, the corresponding alert action can be actively performed without the operator using an additional specific software. Inspection and detection operations can immediately remind and inform relevant personnel to take appropriate contingency measures immediately to prevent the entire system from failing or even permanently damaging.

In particular, the present invention is well suited for use in systems that require long-term stable operation, such as providing commercial servers with Internet finance, commodity trading functions, or monitoring specific locations such as ships, weapons manufacturing, nuclear power plants, bank safe rooms, and the like. The video security server, because of the high stability of the operation of such systems, does not allow the operation of the system to malfunction or fail. Therefore, usually at least three power supply units are arranged in the power supply, and when two or more power supply units cannot be powered normally, the backup power must be activated and the abnormal power supply unit is replaced to ensure the stability of the power supply. Sex, and the invention can be used in two or more power supply lists When the unit is unable to supply power normally, it immediately takes the initiative to use the warning actions indicated by text, image and light to remind the operator. It does not require the operator to perform any detection or detection actions, such as checking the temperature number of the thermometer, and directly according to the warning action. Take the necessary precautions to take valuable reaction time.

In addition, for the temperature overheating of certain components in the system, the operator usually cannot directly know, but must manually execute a specific software program, drive the system to detect the temperature, and view the detection results, in order to take necessary measures. This wastes a considerable amount of time and does not immediately avoid the loss. The method of the present invention can actively determine whether a temperature anomaly occurs, and notifies the operator with a message of sound, text, graphic, image or video, so that the operator only needs to rely on the content of the message. , you can immediately take control actions directly, strive for timeliness, and reduce possible losses.

The method of the invention can also generate a corresponding message for the system event, and the basic input and output system controls the appropriate unit to perform necessary actions to remind the operator, thereby instantly solving the problem caused by the system event and avoiding system downtime or Failure, improve the operational stability of the system.

The above is only a preferred embodiment for explaining the present invention, and is not intended to limit the present invention in any way, and any modifications or alterations to the present invention made in the spirit of the same invention. All should still be included in the scope of the intention of the present invention.
