Example 1
The embodiment of the present invention provides a method for detecting a state of a backflow valve, referring to fig. 1, including the following steps:
s100, performing hardware topology connection, additionally arranging an electromagnetic reset device on a reflux valve of a server, respectively connecting a BMC (baseboard management controller) with the electromagnetic reset device and a fan in the server, connecting a GPIO (general purpose input/output) pin in the BMC with one side of the reflux valve and a high potential, and grounding the other side of the reflux valve;
it should be noted that the high voltage level is equivalent to a power supply, and the high voltage level is continuously generated when the server is powered off, and is not controlled by the power supply in the server.
S200, when a fan in the server normally runs, the fan sends a FANTACH signal, when the BMC does not detect the FANTACH signal, the fan in the server has an abnormal fault or cannot run or normally stops working, the BMC sends a control signal to the electromagnetic reset device to reset the electromagnetic reset device, and the electromagnetic reset device resets to automatically close the counter-current valve so as to prevent the air flow of other fans from flowing out of the fan hole of the fan;
and when the BMC detects a FANTACH signal; the BMC does not send a control signal to stop the electromagnetic resetting device, and the reflux valve is in an open state at the moment;
s300, when the server normally supplies power to the fan and the BMC detects FANTACH, detecting the state of the reflux valve, judging whether a first fault occurs according to a detection result, and reporting the first fault to the server if the first fault occurs;
the method comprises the following specific steps:
monitoring the level state of a GPIO pin of the BMC, wherein if the pin for monitoring the GPIO pin is in a low level state, the reverse flow valve is in a closed state, and copper sheet clamping latches on the fan are mutually communicated;
then the fan fault abnormality occurs or the reverse flow valve fails at this time; recording the fault at the moment through the BMC and reporting the fault to the server;
if the pin of the GPIO is detected to be high level, the reflux valve is in an open state, at the moment, the reflux valve is in a normal state, and the BMC detects a FANTACH signal; at the moment, the reverse-flow valve does not have a fault;
when the server normally supplies power to the fan and the BMC does not detect FANTACH, the fan goes wrong; reporting the information of the fault of the fan to a server;
s400, when all the direct current power supplies in the server are closed, detecting the state of the reverse flow valve, judging whether a second fault occurs according to the detected state of the reverse flow valve and the detection result, and reporting the second fault to the server if the second fault occurs;
the method comprises the following specific steps:
it should be noted that there are two cases when the dc power supply is turned off, the first case is when the user needs to turn off all the main dc power supplies according to the requirement, at this time, because the server does not perform any processing service, the fan does not need to be operated, but the stand by power supply in the server still works;
the Stand by power supply is a standby power supply.
The second situation is that only the stand by power supply is started before the server is powered on with alternating current and the power supply module in the server does not convert the alternating current into the direct current power supply;
the BMC uses a stand by power supply, so that whether the closing state of the reverse flow valve is normal can be detected when the direct current power supply is closed;
at the moment, the fan does not run, a FANTACH signal is not sent, the BMC sends a control signal to enable the reverse flow valve to be in a closed state, monitoring is carried out through a GPIO pin of the BMC, when the GPIO pin is detected to be in a high level, the reverse flow valve is in an open state, therefore, foreign matter is stuck at the position of the reverse flow valve, or the reverse flow valve breaks down, the fault of the BMC is recorded, and the fault is sent to the server;
when the pin of the GPIO is detected to be in a low level, the reverse flow valve is normally in a closed state and has no fault.
It should be noted that, if the ground position and the high potential are interchanged, the detection of the state of the reflux valve can also be realized, but after the positions are interchanged, the high level of the GPIO pin corresponds to the state of the reflux valve and is in a closed state, but the reflux valve is electrified, and the GPIO pin does not conform to the physical logic on a conventional server, so that the high level of the GPIO pin corresponds to the open state of the reflux valve, and the low level of the GPIO pin corresponds to the closed state of the reflux valve.
