[0002] The application of the existing domestic server whole machine to the acquisition monitoring of the working state of ATX power supply and mainboard card in the case is still in the blank stage. Currently, for the server whole machine case, the working state of ATX power supply in the case can only rely on the simple alarm prompt of the ATX power supply module itself, although the ATX power supply module itself also has buzzer alarm and LED indicator alarm, but the ATX power supply module is installed in the case, and the working environment of the server whole machine case is relatively noisy, so the buzzer alarm sound in the power supply module will be relatively small, and it is difficult for the operator to judge when the alarm occurs.

[0003] At the same time, it is also difficult to directly use the LED indicator light on the ATX power supply module to be installed on the structure panel for direct viewing and judgment outside the case, and a specific mounting structure needs to be designed on the structure, which will increase the installation difficulty and the workload of subsequent maintenance. For the working state of the mainboard in the case, the existing application environment can only measure the relevant power signals of the mainboard to judge the working state of the mainboard when the mainboard fails, which is inconvenient to use, therefore, it needs to be improved.

[0015] The server whole machine ATX power supply and board state monitoring alarm system can solve the problem that the buzzer alarm sound in the internal power module of a traditional server case is relatively small, and it is difficult for an operation user to judge when an alarm occurs, and after the monitoring chip judges the working states of the power supply and the board, the LED indicator, the buzzer and the liquid crystal screen connected with the back plate are controlled to send out a warning to the outside, so that a staff member can more intuitively check the state of the case, and the practicability is high. BRIEF DESCRIPTION OF DRAWINGS

[0016] Figure 1 It is a principle diagram of the server whole machine ATX power supply and board state monitoring alarm system. DETAILED DESCRIPTION

[0017] The server whole machine ATX power supply and board state monitoring alarm system will be described in detail below in combination with the drawings and specific embodiments.

[0018] Referring to Figure 1 The server whole machine ATX power supply and board state monitoring alarm system comprises a back plate installed on the back of a server case, a monitoring chip installed on the back plate, and a warning module, a panel and a display module connected with the monitoring chip, in an embodiment, the monitoring chip is connected with an ATX redundant power supply in the server through an SMBUS interface, and the monitoring chip is connected with each mainboard in the server through an I2C interface; the monitoring chip is used for monitoring the working states of the ATX redundant power supply and the mainboard, and sending out warning information to the outside through the warning module, the panel and the display module.

[0019] In this embodiment, the monitoring chip adopts a chip model of GW1N-LV4QN88; the monitoring chip controls the warning module (in this embodiment, the warning module includes a buzzer) to work through a PWM interface; an indication module (in this embodiment, the indication module includes an LED indicator) is further arranged on the panel, and the monitoring chip controls the indication module to work through a GPIO interface; the monitoring chip controls a display module (in this embodiment, the display module includes a liquid crystal screen) to work through a UART interface.

[0020] The monitoring chip of the utility model can monitor the working state of the ATX redundant power module and the mainboard through the relevant communication interface, and display and alarm through the buzzer independently led out by the case back plate, the LED indicator and the liquid crystal screen of the panel; after the monitoring chip monitors various working states of the ATX redundant power module and the mainboard, the PWM signal of corresponding specific frequency is output to drive the buzzer to sound, the GPIO control signal is output to control the LED indicator of the panel, and the serial port signal of 3.3V level is output to the liquid crystal screen to display relevant information.

[0021] In this embodiment, the monitoring chip obtains the working state of the ATX redundant power module (including whether the power AC input is normal, whether each DC output is normal, whether there is OVP / OCP / OTP fault, etc.) through an SMBUS interface, and simultaneously obtains the system temperature, the power voltage and other information of each mainboard of the whole machine case through an I2C interface.

[0022] Meanwhile, the monitoring chip can also control and manage the power of the whole machine case; when the monitoring chip detects that a low pulse level appears in the on-off key signal of the whole machine panel, a high level control signal, namely the PSON signal of the ATX power, is output, and when the ATX_PWR_OK output by the ATX power changes from high level to low level, the relevant control signal is output to control the mainboard of the case to execute power-on; when it is needed to make the whole machine perform hard shutdown, the monitoring chip outputs the relevant control signal to control the mainboard of the whole machine to execute shutdown by detecting the signal for more than 4S by pressing the panel switch key, and then informs the ATX power to execute power-off.

[0023] When the case is in failure, the monitoring chip judges the relevant signals output by the ATX power and the mainboard to judge which stage the power-on timing card is in, which causes the whole machine to fail to normally power on; the power of the monitoring chip is supplied by the standby power of the case (when the AC 220V power outside the case normally supplies power, the ATX power will output a 5V standby power by default), so even when the ATX power is abnormal, the relevant control signal can be output to make the buzzer and the indicator realize sound and light alarm, and the relevant alarm information can be displayed on the liquid crystal screen.

[0024] The utility model discloses can solve the problem that the traditional server case power module inside buzzer alarm sound can be smaller, when appearing alarm, the operation user is difficult to judge, and through the monitoring chip judgement power and board card working condition, control and the LED pilot lamp of backboard connection, buzzer and liquid crystal screen send warning to outside, convenient for staff more intuitive view the state of case, and the practicality is strong.

[0025] The above is only the preferred embodiment of the utility model, and is not used for limiting the utility model, and any modification, equivalent replacement and improvement etc. that are made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
