Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 to 3, the energy-saving control system with intelligent management server heat dissipation provided by the present invention is applied to one or more servers, where the servers are devices capable of automatically performing numerical calculation and/or information processing according to preset or stored instructions, and the hardware includes, but is not limited to, a microprocessor, an Application Specific Integrated Circuit (ASIC), a Programmable Gate Array (FPGA), a Digital Signal Processor (DSP), an embedded device, and the like.
The server may include a network device and/or a user device. The network device includes, but is not limited to, a single network server, a server group consisting of a plurality of network servers, or a Cloud Computing (Cloud Computing) based Cloud consisting of a large number of hosts or network servers.
In the energy-saving control system with the intelligent management server for heat dissipation, when the server is shut down, the fan with small heat dissipation effect on the small system stops working, and the power consumption is reduced.
The invention provides an energy-saving control system with intelligent management server heat dissipation, which comprises: a server monitoring subsystem;
the server monitoring subsystem includes: the feedback regulation component is connected with the power supply component; the power supply assembly is provided with a power supply board and a signal control board, the power supply board is connected with a fan back board through a power supply cable, and the fan back board is connected with the fan group to supply power to the fan group; the control end of the fan set is connected with the BMC module of the server through the signal control board; the feedback regulation component is provided with an IIC link module; the BMC module acquires a TACH signal of the fan group through the IIC link module, and controls the rotating speed of the fan through PWM speed regulation according to a preset heat dissipation strategy. In the control process of the BMC module, the BMC module acquires the operating state data of the fan group and the temperature of a CPU of the server through the IIC link module.
The fan set related by the invention is provided with a plurality of groups of fan modules, and at least one fan module is arranged close to the server monitoring subsystem. When the server normally operates, the fan module can radiate heat inside the server, and if the server is shut down, part of the fans can be started as required to radiate the heat of the server monitoring subsystem.
The signal control board is provided with a CPLD module; and the control end of the fan set is connected with the BMC module of the server through the CPLD module of the signal control board. The CPLD module is connected with the BMC module to acquire the on-off state information of the server, and after the server is turned off, the fans in the fan set close to the server monitoring subsystem are controlled to continue to operate.
That is, after the server is shut down, the corresponding fans are set to continuously operate as required and blow to the server monitoring subsystem to dissipate heat of the server monitoring subsystem, so that part of the fans are not affected by the on-off of the server, and the heat of the server monitoring subsystem can be dissipated in an independent control mode.
Illustratively, a PSU power supply module is arranged on the power supply board; the signal control board is also provided with MOS enabling modules, a resistor R1 and a resistor R2, wherein the number of the MOS enabling modules is matched with that of the fan modules in the fan set; the CPLD module is connected with the input end of the MOS enabling module through a resistor R1; the PSU power supply module is connected with the input end of the MOS enabling module through a resistor R2; the output end of each MOS enabling module is correspondingly connected with one fan module. The system realizes that the enable pin of the MOS enable module is pulled high all the time, so that the fan can be ensured to work continuously as long as the PSU power supply module has output voltage. And if the MOS enabling module is not pulled high, the fan module connected with the MOS enabling module does not run.
Specifically, when the power supply is at a high level, the server is considered to be in a power-on state, at this time, the CPLD module pulls up the MOS enable module enable pin on the fan board, so that the MOS enable module pipe is in a working state, and 12V of the PSU power supply module can be directly supplied to the fan, so that the fan works normally. When the server is shut down, if the CPLD module outputs low level to the MOS enabling module, the MOS enabling module is in a closed state, and the fan cannot be powered. Through the design, the change of the power supply of the fan along with the startup and shutdown of the server is realized.
The invention provides an energy-saving control system with intelligent management server heat dissipation, which reduces the power consumption of a server and prolongs the service life of a fan.
Based on the above system, the present invention further provides an energy saving control method with intelligent management server heat dissipation, it should be understood that the sequence numbers of the steps in the above embodiment do not mean the sequence of execution, and the execution sequence of each process should be determined by its function and internal logic, and should not constitute any limitation to the implementation process of the embodiment of the present invention.
As shown in fig. 4, the method includes: s101, starting a server;
s102, supplying power to the fan set through a power supply cable by the PSU power supply module, and enabling the fan set to operate to dissipate heat of internal elements of the server;
s103, the BMC module acquires the running state of the fan set through the signal control board;
and S104, the BMC module acquires a TACH signal of the fan group through the IIC link module, and the BMC module controls the rotating speed of the fan through PWM speed regulation according to a preset heat dissipation strategy.
Specifically, when the server is powered off, the BMC module sends a power-off signal to the CPLD module;
and the CPLD module controls fans in the fan set close to the server monitoring subsystem to continue to operate.
For example, for the power supply mode of the invention, because the fan is in the highest priority position in the operation of the server, in the server with a small system, the fan can rotate at the moment when the server is powered on, the power supply board of the invention is directly connected by the PSU12V, and the design that the fan is powered on at the moment when the machine is powered on is ensured.
When the server is shut down, the CPLD module sends control information to the control end of the MOS enabling module, so that the PSU power supply module supplies power to a fan close to the server monitoring subsystem, and the fan runs.
When the server is started to operate, the BMC module acquires the operating state data of the fan set and the temperature of the CPU of the server in real time through the IIC link module, and controls the rotating speed of the fan through PWM speed regulation according to a preset heat dissipation strategy.
By the mode, when the server is normally started and operated, all the fan modules normally operate in power supply mode, and the rotating speed of the fan is only regulated and controlled by the BMC module. And when the server is shut down, the fan is continuously regulated and controlled according to the temperature fed back by the server monitoring subsystem because the server monitoring subsystem is in operation. However, due to the position of the server monitoring subsystem, some fan modules cannot radiate heat for the server monitoring subsystem, the function of obtaining the fan modules is not enough, and at the moment, the fan only wastes electricity in vain. But only to power the useful fan modules. And ensuring the operation of the server monitoring subsystem.
The fan set is provided with a plurality of fan modules, codes can be set for each fan module, if the codes close to the server monitoring subsystem are identified and sent to the BMC module and the CPLD module, and when the fan modules are controlled, the corresponding fan modules can be effectively controlled.
The server is powered on and powered off, a notification signal enters the BMC module so as to judge the current state of the server, the power on and power off signal is accessed into the CPLD module, and the CPLD module carries out logic judgment according to the signal level.
