Abstract
A kind of separate fan controller for machine box for server, which includes the temperature sensor being connected with microcontroller, for detection service device housing temperature.Microcontroller is connected with least six fan base, and the line of these fan bases is used for the radiator fan for connecting control machine box for server, and microcontroller connection buzzer, alarms for abnormal temperature in cabinet.Fan base is small 4P fan bases, and fan base contact pin has 4, is respectively labeled as PWMIN, PWMOUT ,+12V, GND.
Description
Technical field
The utility model belongs to computer server technical field, more particularly to a kind of independent wind for machine box for server
Fan controller.
Background technology
In the patent document of Publication No. CN104571273A, mention that " for server, radiating control is always
Its important link ... traditionally, all central processing unit substrates are all by unified fan control in each cabinet
System carries out fan cooling control.Once this fan control system is damaged, cabinet will be caused not radiate, even damaged internal
Server ".Especially, the hard disk of storage server insertion can produce substantial amounts of heat, it is also desirable to which fan radiates.It can be seen that fan
Fan control of the controller for server be and its important.In general, in existing major part machine box for server, for radiating
Or fan governor do not have temperature control speed governing, or just directly radiator fan is connected on mainboard, so may result in
CPU supply voltages are insufficient and power-consuming not energy saving enough.
Utility model content
A kind of separate fan controller for machine box for server, fan governor circuit and the discrete peace of server master board
Dress, the fan governor circuit include the temperature sensor that is connected with microcontroller, for detection service device housing temperature,
Microcontroller is connected with least six fan base, and the line of these fan bases is used to connect dissipating for control machine box for server
Hot-air fan, wherein 3 fan bases are used for spare fans, meanwhile,
Microcontroller connects buzzer, alarms for abnormal temperature in cabinet,
Fan governor circuit further includes one big 4P power outlets, for being introduced directly into power supply from server power supply.
Fan base is small 4P fan bases, and fan base contact pin has 4, is respectively labeled as PWMIN, PWMOUT ,+12V, GND.
Microcontroller uses STM8S103F3P6, and temperature sensor uses NTC thermistor.
Fan governor further includes one big 4P power outlets.
If the fan governor of the utility model has the function of intelligent temperature control, wind can voluntarily be adjusted according to environment temperature
Rotating speed is fanned, when environment temperature raises, rotation speed of the fan improves；When environment temperature reduces, rotation speed of the fan reduces.If fan is due to certain
Failure shuts down or environment temperature is too high, and buzzer can buzzing.The utility model realizes the mesh to server hard disc heat dissipation
, protect hard disk；Meanwhile when the environment temperature decreases, rotation speed of the fan is reduced automatically, achieve the purpose that power saving.
Brief description of the drawings
Detailed description below is read by reference to attached drawing, the utility model illustrative embodiments above-mentioned and other
Objects, features and advantages will become prone to understand.In the accompanying drawings, show that this practicality is new by way of example, and not by way of limitation
Some embodiments of type, wherein：
Fig. 1 is the theory of constitution schematic diagram of the utility model.
Embodiment
The utility model can include with lower part：
(1) temperature sensing portion：Using the thermistor of NTC as temperature sensor, induced environment temperature.
(2) control circuit part：By the use of STM8S103F3P6 microcontrollers as core component, using its PWM function to fan
Carry out speed governing.
(3) alarm portion:Buzzer interface is the distinctive module of STM8, it produces the square wave of a specific frequency
To drive passive buzzer.Its hardware is connected to the pin PD4 of chip, and can produce frequency when LS clock works are in 128KHz is
The buzzerphone of 1KHz, 2KHz or 4KHz.When environment temperature is excessive or fan is since failure is stopped, buzzer can bee
Ring.
(4) fan section：Six small 4P fan bases are devised on pcb board, are worked at the same time for six fans, small 4P wind
Fan seat has four pins, is from left to right that PWMIN, PWMOUT ,+12V, GND are formed successively, wherein PWMIN, PWMOUT are exactly conduct
Signal transmission passage, the signal that it is transmitted according to temperature sensor judge whether fan needs to carry out carry out speed governing.
(5) heat dissipation installation：Fan board is placed in machine box for server, and the fan in server is inserted in the PWM of fan board
On fan interface, be powered, fan can normally rotate give server cooling；When the hard disk temperature rise in machine box for server, fan
Faster rotational speed.
What deserves to be explained is created although foregoing teachings describe the utility model by reference to some embodiments
Spirit and principle, it should be appreciated that, the utility model is not limited to disclosed embodiment, and each side is drawn
Divide and also do not mean that the feature in these aspects cannot combine, this division is merely to the convenience of statement.The utility model purport
Covering various modifications and equivalent arrangements included in spirit and scope of the appended claims.
