In fig. 6, the Vs pin may provide an operating power supply for the liquid level sensor, the OUTPUT pin is an OUTPUT terminal of the liquid level sensor, the OUTPUT signal may be a TTL level signal, when the liquid level sensor is in the air, the OUTPUT signal is a low level, and when the liquid level sensor is in a liquid cooling medium, the OUTPUT signal is a high level. OUTPUT OUTPUT of liquid level sensor can connect the input of controller, when OUTPUT exports low level, then liquid level sensor is judged in the air to the controller, when OUTPUT exports high level, then liquid level sensor is judged in the liquid cooling medium to the controller. 0V is a ground signal, providing a ground return.
Fig. 7 is a circuit diagram of a power OUTPUT control circuit of an exchanger according to an embodiment of the present invention, where OUTPUT is an OUTPUT of a liquid level sensor corresponding to a CPU module.
When the selector switch is in the position 1, the power control function is not started, at the moment, Q1 is conducted, Q2 is cut off, PSON is always in a high level, and the power supply of the whole machine is normally started and is not controlled by an electric signal output by the liquid level sensor.
When the selector switch is in the position 2, a power supply control function is started, the state of the PSON is controlled by an electric signal output by the liquid level sensor at the moment, when the liquid level sensor is in the air, the output is low level, at the moment, Q1 is cut off, Q2 is conducted, the PSON is kept at the low level, the power supply output of the whole machine is closed, and the whole machine is in a power-off state; when the liquid cooling medium submerges the CPU module, the liquid level sensor is positioned in the liquid cooling medium, the output pin of the liquid level sensor is at a high level, the Q1 is controlled to be switched on, the Q2 is controlled to be switched off, the PSON is changed into a high level, the power supply of the whole computer is powered on at the moment, the CPU module and the BMC module are normally started, and the whole computer software starts to work.
The user selects according to the current service condition of the equipment, when the equipment is used in a debugging state, the heat dissipation of the equipment is ensured to meet the requirement, for example, under the condition of air cooling heat dissipation, the power supply control function can be selected to be turned off, at the moment, the switch is the same as the traditional switch, after the power supply is powered on, the whole machine starts to be powered on, the system is initialized normally, the local power supply control is not performed any more, and the equipment can perform full-performance work after being started.
The user uses in the liquid cooling environment, the optional power control function that opens, at this moment, the power of equipment is electrified, but the complete machine is in the outage state, and power output is 0, and until the liquid level that the hardware circuit monitored the liquid cooling medium satisfies the basic heat dissipation demand of equipment, control power output this moment, CPU module can normally work, and equipment software normal operating, basic control and the remote control of equipment can normally realize.
The following describes the power control method provided in the present application in detail.
And after receiving a second signal output by the liquid level detection device, controlling a second power supply corresponding to a switching module of the equipment and at least one third power supply corresponding to a port module to be powered on.
And when the liquid level is not lower than the second preset height, at least one third power supply corresponding to the port module of the control equipment is powered on.
In specific implementation, after receiving the second signal output by the liquid level detection device, if receiving a third signal output by the liquid level detection device, controlling all third power supplies of the device to be powered on, where the third signal is sent after the liquid level detection device detects that the liquid level height is not lower than a third preset height, and the third preset height is higher than the second preset height.
Because the liquid level height is not lower than the third preset height, namely the port module is completely or partially immersed in the liquid cooling medium, all power supplies corresponding to the port module can be controlled to be powered on, and all the port modules can work normally.
After receiving the second signal output by the liquid level detection device, if receiving a fourth signal output by the liquid level detection device, the third power supplies of the preset number can be controlled to be powered on, wherein the fourth signal is sent after the liquid level detection device detects that the liquid level height is lower than a third preset height.
Because the liquid level is lower than the third preset height, the port module is not immersed in the liquid cooling medium, and the heat dissipation of the port module is not very large when the port module works, the power supplies corresponding to the preset number of port modules can be controlled to be powered on, so that the powered-on port modules can work normally.
The predetermined number of port modules may be spaced apart from each other. For example, if there are 5 port modules, the power supplies corresponding to the 1 st port module, the 3 rd port module and the 5 th port module may be controlled to be powered on.
In implementation, after a first power supply corresponding to the CPU module is powered on, if a fifth signal and a fourth signal output by the liquid level detection device are received, the second power supply and the third power supply are controlled to be powered off or to maintain a non-power state, where the fifth signal is sent after the liquid level detection device detects that the liquid level is lower than a second preset height;
the first power supply is powered on, the CPU module is completely or partially immersed in the liquid cooling medium, the liquid level detection device outputs a fourth signal, the port module is not immersed in the liquid cooling medium, the liquid level detection device outputs a fifth signal, the exchange module is not immersed in the liquid cooling medium, and therefore in order to enable the equipment to normally dissipate heat, the second power supply and the third power supply need to be controlled to be powered off, or the second power supply and the third power supply need to be maintained in a non-power state.
In implementation, after the first power supply corresponding to the CPU module is powered on, if the fifth signal and the third signal output by the liquid level detection device are received, an alarm operation is performed.
The third signal is sent after the liquid level is not lower than the third preset height, the fifth signal is sent after the liquid level is lower than the second preset height, and the second preset height is lower than the third preset height, so that the situation shows that the liquid level detection device possibly has faults, and the alarm operation can be carried out.
In the power control method provided by the embodiment of the invention, if a sixth signal output by the liquid level detection device is received, the first power supply is controlled to be powered off or to be in a non-power state, wherein the sixth signal is sent after the liquid level detection device detects that the liquid level is lower than a first preset height.
If the liquid level is lower than the first preset height, the CPU module is not immersed in the liquid cooling medium, so that the first power supply is powered off or the first power supply is maintained in a non-electricity state.
The first signal may be at a high level, the second signal may be at a high level, the third signal may be at a high level, the fourth signal may be at a low level, the fifth signal may be at a low level, and the sixth signal may be at a low level.
The liquid level detection device detects the liquid level height, and can detect the liquid level height periodically, for example, once in 10 ms.
