Additionally, the utility model Method And Principle reliability, step is simple, with application prospect widely.
As can be seen here, the utility model compared with prior art, with substantive distinguishing features and progress, its beneficial effect implemented
Fruit is also obvious.
Description of the drawings
Fig. 1 is a kind of structural representation of fan control system that the utility model is provided.
Fig. 2 is a kind of circuit diagram of the logical control circuit of fan control system that the utility model is provided.
Wherein, 1- fan governors, 2- monitoring chips, 3- logical control circuits, 4- fans.
Specific embodiment
Below in conjunction with the accompanying drawings and by specific embodiment the utility model is elaborated, and following examples are to this
The explanation of utility model, and the utility model is not limited to implementation below.
As shown in Fig. 1 to 2, the utility model provide a kind of fan control system, including fan 4, fan governor 1,
The logical control circuit 3 of monitoring chip 2 and fan 4；The fan governor 1 transmits control signal PWM_Q to hardware logic
Controller 3, logical control circuit 3 controls fan 4 by output signal PWM；The transmission of fan governor 1 input signal WDI is extremely
Monitoring chip 2, monitoring chip 2 transmits output signal WDO to logical control circuit 3.
Wherein, pwm signal is used to make the normally control rotating speed of fan 4 of fan governor 1, is formally the square wave of 10 to 90kHZ.
In the present embodiment, pwm signal is 40kHz square waves.
In the present embodiment, the logical control circuit 3 is made up of NMOS, PNP, resistance and electric capacity, and wherein NMOS is
NX7002 model components, PNP is PMBT3906 model components.
In the present embodiment, the monitoring chip 2 is MAX6396 watchdog chips.
In the present embodiment, model AST2400 of the fan governor 1.
In the present embodiment, WDI and WDO are respectively the input and output signals of monitoring chip 2, when monitoring chip 2 is monitored
When there is control signal PWM_Q, input signal WDI is square wave, and output signal WDO is height；Otherwise, output signal WDO is height
The 1kHz square waves of low change.
In a kind of fan control system provided using the utility model, when fan governor 1 can normal work when,
The normal output rule square waves of PWM_Q, WDO is height, and PNP shut-offs, Q1 shut-offs, Q2 is opened, it is ensured that PWM_Q can be given with normal delivery
PWM, fan 4 is normally controlled.
On fan governor 1 during electric or failure, control signal PWM_Q cannot be exported normally, and monitoring chip 2 is just monitored not
To rule square wave, the square wave that output signal WDO is height conversion will be pushed away, the inner PNP for using of logical control circuit 3 is in input
For it is low when open and charged to electric capacity, it is ensured that electric capacity is in high voltage level, opens adjacent mos Q1, closes PWM_Q and pwm signal
Between MOS Q2, so as to completely cut off fan governor 1 and fan 4PWM PINs, due to having pull-up inside fan 4PWM PIN
Resistance, makes PWM be always maintained at height, and fan 4 is rotated at full speed, and when this ensure that fan governor 1 fails, system will not heat up.
A kind of fan control system that the utility model is provided, using the wave character of normal fan control signal PWM,
Monitor whether fan governor 1 fails by monitoring chip 2, when fan governor 1 normally runs, perform normal control plan
Slightly；When fan governor 1 fails, the proper heat reduction work of fan is ensured by hardware controls link.
The above, is only preferred embodiment of the present utility model, and any pro forma limit is not done to the utility model
System, it is all to make any modification, equivalent and improvement etc. within spirit of the present utility model and principle, should be included in this reality
Within new protection domain.
