Embodiment one
The flow chart of the fan speed-governing method that Fig. 1 provides for the embodiment of the invention one.The executive agent of present embodiment is a fan speed adjusting device, and as shown in Figure 1, the fan speed-governing method of present embodiment comprises:
Wherein, the fan speed adjusting device of present embodiment can be independent of the equipment of present embodiment, also can be used as the functional part in the equipment of present embodiment, is arranged in the equipment.Concrete, the port on the equipment is meant the physical interface on the equipment, other equipment are used to peg graft.For example, mainly be arranged at the port at cabinet back on the desk top computer, comprise the round mouth SP2 interface that connects keyboard and mouse, LPT interface (being usually said parallel interface), com interface (being serial line interface), COBBAIF, network interface card interface and the display interface device etc. that connect printer.Again for example, be used to connect a plurality of ports of the equipment of access network on switchboard or the router, also belong to the category of the port on the equipment in the present embodiment.Usually, the power consumption of port when user mode and idle condition is inequality, and therefore, port is in different working staties, and the total power consumption that means equipment is with difference.And the above-mentioned power consumption of same equipment different port is not quite similar, and the power consumption of the port of distinct device is also different.And the power consumption of equipment can be changed to user mode or by the variation of user mode to idle condition by idle condition because of port, and therefore, fan speed adjusting device will obtain the working state changed port in this step 101.At this, the factor that needs explanation to influence the total power consumption of equipment also has a lot, will pay close attention to the port factor in the present embodiment, and other factors are not done description.
Fan speed adjusting device is after getting access to the working state changed port, and correspondence is obtained the performance parameter of port.Wherein, the performance parameter of each port is stored in the fan speed adjusting device in advance, its concrete file layout present embodiment does not limit, form that for example can data list, then in this data list, store the performance parameter of port simultaneously, and the mapping relations between port and its performance parameter, these mapping relations are used to make fan speed adjusting device to find the performance parameter of port correspondence after getting access to port.
The performance parameter of present embodiment mainly is meant the power consumption when each port is in idle condition and user mode, is referred to as the port power consumption.Wherein, fan speed adjusting device can the storage port correspondence power consumption, the power that also can store each port correspondence (for example, power when power is with use when idle), can also store the electric current (for example, electric current and electric current when using when idle) of the correspondence of each port, moreover any combination of power consumption, power and electric current that also can the storage port correspondence (for example, the power and the electric current of while storage port correspondence, the perhaps power consumption of while storage port correspondence and electric current etc.).Because distinct device may provide the performance parameter of its port with different forms, therefore, the information of the sign performance parameter of being stored in the fan speed adjusting device specifically can be decided because of equipment.And how find the solution the technological scheme of power consumption according to power or electric current, and belonging to those skilled in the art's common practise, present embodiment is not done detailed argumentation.
Wherein, the power consumption variation information of equipment correspondence can be current power consumption, variation power consumption and the change of power consumption trend etc. of equipment.Fan speed adjusting device is according to the working state changed port corresponding port power consumption and the port work at present state that obtain, can obtain the current power consumption of equipment, and, obtain the variation power consumption and the change of power consumption trend of equipment correspondence by comparing with the power consumption before the equipment.
Wherein, the corresponding relation between power consumption-rotation speed relation characterization device power consumption and the rotation speed of the fan can obtain by the service manual of equipment usually.Fan speed adjusting device obtains power consumption-rotation speed relation of obtaining in advance after the power consumption variation information of obtaining the equipment correspondence, and obtains the rotating speed adjustment amount of this power consumption variation information correspondence according to power consumption-rotation speed relation; Wherein, the rotating speed adjustment amount is meant to overcome and changes the temperature variation that power consumption causes, the adjustment amount that need make the rotating speed of fan.
Usually under the situation of extraneous environment facies to stable (for example can not occur thermal source or cooling system etc. suddenly), device temperature is mainly determined by equipment power dissipation, and owing to temperature can not be undergone mutation, be that variation of temperature is a process that slowly changes, therefore, fan speed adjusting device is when obtaining the rotating speed adjustment amount, and the temperature of equipment does not change as yet or significantly changes.Therefore, the fan speed adjusting device of present embodiment can promote the rotating speed of fan according to rotating speed adjustment amount (being the rotating speed amount of required lifting) before temperature rises, to suppress the rising of temperature; Also can before descending, temperature reduce the rotating speed of fan, to prevent the reduction of temperature according to rotating speed adjustment amount (being the rotating speed amount of required reduction).
The fan speed-governing method of present embodiment, by obtaining working state changed port on the equipment, and then obtain because of the change variation of caused equipment power dissipation of port working state, before device temperature changes by obtaining the rotating speed adjustment amount that changes the power consumption correspondence, according to this rotating speed adjustment amount the rotating speed of fan is adjusted, with the suppression equipment variation of temperature, make equipment work under metastable temperature environment, and then prolong the working life of equipment.
In the above-described embodiments, can store power consumption-rotation speed relation in advance in the fan speed adjusting device, then fan speed adjusting device can directly obtain the power consumption-rotation speed relation that is stored in advance wherein, to be used to obtain the rotating speed adjustment amount.Wherein, power consumption-rotation speed relation can be obtained in advance and store in the fan speed adjusting device by operations such as numerical analysis or numerical fittings according to the power consumption-temperature relation of equipment and the rotating speed-temperature relation of fan by operator.And the rotating speed-temperature relation of the power consumption-temperature relation of equipment and fan can obtain by the service manual of equipment.
But, because the power consumption-temperature relation of every equipment and the rotating speed-temperature relation of fan can be different because of equipment, and be mostly to describe above-mentioned relation usually with curve form, therefore, fan speed adjusting device is the power consumption-temperature relation of memory device and the rotating speed-temperature relation of fan in advance, and according to the above-mentioned relation of storage in advance obtain in real time described power consumption-rotation speed relation be a kind of more preferred embodiment.Under this mode, fan speed adjusting device can inquire about that power consumption-(temperature information can comprise the temperature that will rise to temperature relation curve acquisition temperature information according to power consumption variation information, transformation temperature and temperature changing trend etc.), according to temperature information inquiry rotating speed-temperature relation curve acquisition rotating speed adjustment amount, promptly obtain power consumption-rotation speed relation in real time, this mode is carried out the operation of obtaining power consumption-rotation speed relation by fan speed adjusting device, operation is simple for it, and in the degree of accuracy and precision of the power consumption-rotation speed relation that guarantees to obtain, alleviated operator's burden greatly.
Further, present embodiment provides the mode of execution that a kind of fan speed adjusting device obtains the working state changed port, i.e. the state of the port on the fan speed adjusting device timing scan equipment.For example, fan speed adjusting device is the power supply by powering for each port on the monitoring equipment mainly, when finding that power supply changes, and then by the voltage of each port of scanning or the size of electric current, with judgement is that variation has taken place for the working state of which or which port, and then obtains the working state changed port.
In order further to improve the working efficiency of fan speed adjusting device, present embodiment provides a kind of mode of execution that obtains the working state changed port in addition, be specially: equipment changes at port status (for example has user mode to become idle condition, perhaps become user mode by idle condition) time, interrupt signal sent to fan speed adjusting device; And can there be the working state changed port in fan speed adjusting device on the judgment device according to the interrupt signal that receives, and then equipment is inquired about, to obtain working state changed port on the equipment.Under this mode,, therefore, can handle other things, improve its working efficiency at other moment fan speed adjusting devices because fan speed adjusting device when receiving interrupt signal, is just carried out search operation, and resource utilization.Further, the support of combined with hardware technology, by setting a plurality of interrupt signal interface, different port on the difference corresponding device, then fan speed adjusting device can be directly according to interrupt signal that receives and corresponding interrupt register, know the state of changing of changed port and port, and need not equipment is inquired about, can further improve the working efficiency of fan speed adjusting device.
Need explanation at this, technical solution of the present invention mainly is the working state according to device port, by adjusting the adjustment of rotation speed of the fan realization to device temperature, therefore, it is more that technical solution of the present invention is particularly useful for port number, perhaps main equipment, for example middle and high end switchboard or router based on port traffic.Therefore, following examples of the present invention will be that example describes technical solution of the present invention in detail with the switchboard.

As shown in Figure 2, the inside of switchboard normally is made of Switching Module 21, administration module 22, port module 23, blower module 24 and power module 25.Wherein, Switching Module 21 is made of a plurality of exchange chips, and each exchange chip is connecting the network interface of some external connections, i.e. port among the present invention.As shown in Figure 2, the Switching Module 21 of present embodiment comprise the 1st exchange chip, the 2nd exchange chip ..., and n exchange chip, wherein n is the integer more than or equal to 1; And each exchange chip is connecting m network interface, and wherein m also is the integer more than or equal to 1, needs explanation at this, and the network interface quantity that each exchange chip connects also can be different, and present embodiment is described to be all example mutually for follow-up being convenient to.As shown in Figure 2, the 1st exchange chip connects network interface RJ45_11 to network interface RJ45_1m, the 2nd exchange chip connects network interface RJ45_21 to network interface RJ45_2m ... and the n exchange chip connects network interface RJ45_n1 to network interface RJ45_nm, and above-mentioned network interface constitutes port module 23.Wherein, present embodiment is an example with network interface card interface RJ45 commonly used in the Ethernet, but is not limited to this.Wherein, Switching Module 21 is connected with administration module 22, and administration module 22 comprises central processing unit (Central Processing Unit; Abbreviate as: CPU) and logic control element (can constitute) by PLD.And administration module 22 is connected with blower module 24, and wherein blower module 24 is made of a plurality of fans, as shown in Figure 2, comprise the 1st fan, the 2nd fan ... and k fan, k is the integer more than or equal to 1.Power module 25 is connected respectively with above-mentioned each module, is used for providing working power to each module.
Wherein, network interface RJ45_11 is used to connect other equipment to network interface RJ45_nm, for example personal computer (Personal Computer; Abbreviate as: PC).Exchange chip is many more by other equipment that network interface connects, and the power consumption of exchange chip is just big more.Usually, for same switchboard, its each exchange chip whenever connects other equipment by a network interface, and the power consumption that exchange chip increases is identical, but is not limited to this.
For for simplicity, present embodiment will make the power consumption increase of exchange chip be all example mutually when whenever connecting other equipment by a network interface, and based on the internal structure explanation technical solution of the present invention of above-mentioned switchboard.Wherein, the administration module in the switchboard is equivalent to fan speed adjusting device of the present invention, promptly in the present embodiment fan speed adjusting device as the function module of equipment (switchboard).As shown in Figure 3, the fan speed-governing method of present embodiment two comprises:
Concrete, on hardware is realized, each exchange chip in the Switching Module 21 all is connected with a interruptive port on the administration module 22, when the every connection of any exchange chip in the Switching Module 21 or when disconnecting a network interface, promptly there is a network interface to be connected or when disconnecting the equipment (for example institute's connection device rolls off the production line) that is connected, just the CPU to administration module 22 sends interrupt signal with other equipment.Wherein the CPU of administration module 22 is according to the interrupt signal interface that receives interrupt signal, can know the source of this interrupt signal, promptly from which exchange chip, it is example that present embodiment will send interrupt signal with the 1st exchange chip, the 2nd exchange chip and n exchange chip.
Wherein, after the CPU in the administration module 22 gets access to interrupt signal, the interrupt register of the exchange chip of this interrupt signal correspondence be can remove to read, the 1st exchange chip, the 2nd exchange chip and the interrupt register n exchange chip promptly read respectively.Then, obtain the interruption source that produces respective interrupt signals from each interrupt register, for example port changes, exchange chip fault etc.Because present embodiment supposition exchange chip is the interrupt signal that sends to CPU when connecting or disconnect port, therefore, CPU inquiry interrupt register knows that the port of exchange chip changes, then inquire about the network interface that the 1st exchange chip, the 2nd exchange chip are connected with the n exchange chip respectively, obtain the network interface that current the 1st exchange chip, the 2nd exchange chip are connected with the n exchange chip.For example get access to that the 1st exchange chip connects network interface RJ45_11, network interface RJ45_12, network interface RJ45_13 are connected with other equipment; The 2nd exchange chip connects network interface RJ45_21, network interface RJ45_22, network interface RJ45_23 are connected with other equipment; The n exchange chip connects network interface RJ45_n1, network interface RJ45_n2, network interface RJ45_n3 are connected with other equipment.Then, by comparing with the network interface that the n exchange chip is connected, know the network interface that changes in each exchange chip with the 1st exchange chip, the 2nd exchange chip before.For example hypothesis gets access to network interface RJ45_11 and the network interface RJ45_12 that the 1st exchange chip connects, and the network interface RJ45_22 that the 2nd exchange chip connects is the newly-increased network interface that is connected with other equipment; And the network interface RJ45_n4 that the n exchange chip connects is the network interface of disconnection institute connection device, and above-mentioned network interface is referred to as to change network interface.
Wherein, store the power consumption of its each network interface in the switchboard in advance, comprise the idle power consumption of work power consumption when not being connected other equipment when connecting other equipment.By calculating the poor of power consumption corresponding before each power consumption that changes network interface work at present state correspondence and the change of state, and the difference of the power consumption of all changes network interface of same exchange chip sued for peace, obtain the variation power consumption and the current power consumption of this exchange chip correspondence.If change power consumption greater than 0, illustrate that then the power consumption of exchange chip increases, temperature will rise; Otherwise, illustrating that the power consumption of exchange chip reduces, temperature will reduce.
Concrete, in the present embodiment, the work power consumption stepping (power consumption of promptly working and idle power consumption poor) of supposing each network interface is 350mW, network interface RJ45_11, network interface RJ45_12, network interface RJ45_22 becomes work by the free time, network interface RJ45_n4 becomes the free time by work, then administration module 22 is known variation network interface RJ45_11, network interface RJ45_12, the 1st exchange chip that network interface RJ45_22 and network interface RJ45_n4 cause, the variation power consumption of the 2nd exchange chip and n exchange chip correspondence is respectively 700mw, 350mw,-350mw, and can obtain current power consumption with power consumption before by changing power consumption.The variation power consumption that further can know whole switchboard correspondence is 7000mw, and the power consumption of switchboard increases, and its temperature will rise.
Need explanation at this, in this step 303, obtain the power consumption variation information of exchange chip correspondence or the power consumption variation information of switchboard, relevant with the placement scheme of whole switchboard.For example: if switchboard has 3 exchange chips (being n=3), but has only 1 very big fan (being k=1), then only need adjust the rotating speed of 1 fan herein, and arbitrarily the state of network interface all the rotating speed with this fan is relevant, so in this step 303, can be described as obtaining the power consumption variation information of switchboard correspondence.If switchboard has 3 exchange chips (being n=3), correspondence also has 3 fans (being k=3), and suppose the mainly responsible heat radiation of each fan to one of them exchange chip, then the change of power consumption of each exchange chip only can influence the rotating speed of its corresponding fan, and can not influence other fans, so in this step 303, can be described as obtaining the power consumption variation information of exchange chip correspondence.With a plurality of exchange chips, and the corresponding fan of each exchange chip is example at present embodiment, and therefore, this step 303 is used to obtain the power consumption variation information of each exchange chip correspondence.
Wherein, store the temperature variant curve of power consumption of exchange chip in the switchboard of present embodiment, promptly power consumption-temperature relation specifically can obtain and store in the switchboard from the exchange chip service manual.Administration module 22 can obtain the temperature of each exchange chip current power consumption correspondence by inquiring about this curve, and the temperature corresponding with power consumption before done difference and obtained information such as temperature variation and temperature changing trend.Figure 4 shows that the power consumption-temperature relation curve of the exchange chip of present embodiment, by inquiring about curve shown in Figure 4, when the power consumption that can know the 1st exchange chip increases to 1800mW by 1100mW, corresponding temperature can increase to 39.1 ℃ by 33.0 ℃, be that temperature variation is 6.1 ℃, being specially temperature will increase by 6.1 ℃; When the power consumption of the 2nd exchange chip increased to 1800mW by 1450mW, corresponding temperature can increase to 39.1 ℃ by 36.3 ℃, and promptly temperature variation is 2.8 ℃, and being specially temperature will increase by 2.8 ℃; When the power consumption of n exchange chip was reduced to 1800mW by 2150mW, corresponding temperature can be reduced to 39.1 ℃ by 41.5 ℃, and promptly temperature variation is-2.4 ℃, is specially temperature and will reduces by 2.4 ℃.
In the present embodiment, store the temperature variant curve of rotating speed of fan in the switchboard in advance, promptly rotating speed-temperature relation also can obtain from the switchboard service manual.Administration module 22 is by inquiring about the rotating speed that this curve can obtain the Current Temperatures correspondence, and the rotating speed corresponding with temperature before does that difference is obtained the rotating speed adjustment amount and to the adjustment mode (promote rotating speed or reduce rotating speed) of fan.Figure 5 shows that the rotating speed-temperature relation curve of the fan of present embodiment, by curve shown in Figure 5, when the temperature that can know the 1st exchange chip increased to 39.1 ℃ by 33.0 ℃, the rotating speed of corresponding fan (for example the 1st fan) need be by 65 revolutions per seconds of (run/second; Abbreviate as: r/s) rise to 96r/s, promptly the rotating speed adjustment amount is 31r/s; When the temperature of the 2nd exchange chip increased to 39.1 ℃ by 36.3 ℃, the rotating speed of corresponding fan (for example the 2nd fan) need rise to 96r/s by 82r/s, and promptly the rotating speed adjustment amount is 14r/s; When the temperature of n exchange chip was reduced to 39.1 ℃ by 41.5 ℃, the rotating speed of corresponding fan (for example n fan) need be reduced to 96r/s by 108r/s, and promptly the rotating speed adjustment amount is-12r/s.Wherein, the 1st fan, the 2nd fan and n fan are respectively that the 1st exchange chip, the 2nd exchange chip and n exchange chip are carried out the most effective fan of temperature control.Further, when having the situation of the shared fan of a plurality of exchange chips in the switchboard layout, shared the 1st fan of the 1st exchange chip and the 2nd exchange chip for example, then should adjust the rotating speed of the 1st fan according to the variation power consumption sum of the 1st exchange chip and the 2nd exchange chip correspondence this moment, this technological scheme those skilled in the art can directly release according to the description of present embodiment.
Concrete, the logic control element in the administration module 22 is responsible for the rotating speed of each fan is adjusted.For example, speed regulating control instruction that logic control element provides according to CPU and the speed governing parameter (being the rotating speed adjustment amount) in the speed regulating control instruction promote 31r/s with the rotating speed of the 1st fan, the rotating speed of the 2nd fan are promoted 14r/s, with the rotating speed reduction 12r/s of n fan.
Pass through aforesaid operations, when the change of power consumption of exchange chip, can go out the variation of temperature trend that causes because of change of power consumption according to the port working status predication, obtain the required rotation speed of the fan of prevention temperature variation, before temperature variation, in advance rotation speed of the fan is adjusted, keep the temperature of exchange chip relatively stable, prolong the working life of exchange chip, and the final control that realizes exchanger temperature is worked switchboard under metastable temperature environment, prolong its working life.
In addition, need explanation once more: the switchboard of present embodiment comprises a plurality of exchange chips and a plurality of fan, and certainly, switchboard also can be to comprise an exchange chip and a fan, or comprises the structure of a plurality of exchange chips and a fan.At this moment, the speed regulating method of present embodiment need be by obtaining the variation power consumption of whole switchboard, and obtain the temperature changing trend that total variation power consumption causes, and then obtain the rotating speed adjustment amount, adjust with rotating speed, reach the purpose of control exchanger temperature single fan.
But, large switch generally includes a plurality of exchange chips and a plurality of fan, the technological scheme of present embodiment can promptly by the most effective fan of each exchange chip temperature control is controlled, realize the temperature controlling to corresponding exchange chip by all fans are controlled separately.Usually; when ambient temperature relatively low; the network interface that wherein some exchange chips connect is stuck with operates at full capacity; and other exchange chip is when all being in idle state; prior art can surpass predefined value because of the temperature that monitors an exchange chip usually, and makes all fans be operated in immediately under the pattern that runs up.Because when fan was worked under the pattern that runs up, its sound can be very big, not only can cause noise pollution, also can waste more power consumption, makes whole set equipment consume higher power consumption under the less situation of working load.By technical solution of the present invention, can control certain separately or a limited number of fan is lowered the temperature to the exchange chip of operating at full capacity, thereby overcome defective of the prior art.
