【Embodiment】
The above-mentioned purpose and its structure of the present invention and characteristic functionally, will be said according to the preferred embodiment of institute's accompanying drawings
It is bright.
Fig. 1 is the block diagram of present system.As illustrated, including one first fan 11 and one second fan 12, this
One fan 11 and second fan 12 are connected to a control end 13, and second fan 12 connects a monitor speed end 14.The control
End 13 connects first fan 11 by an at least power line VCC, a ground wire GND and a driving RCA PWM and should respectively
Second fan 12, control end 13 provides power supply first fan 11 and second fan 12 by power line VCC, then by driving
Dynamic RCA PWM drives first fan 11 and second fan 12 to rotate.
First fan 11 has one first control element 111, and second fan 12 has one second control element 121,
And the first control element 111 of first fan 11 connects the second control element 121 of second fan 12, connection hand therein
Section is for example but the utilization UART that does not limit（Universal asynchronous receiving-transmitting transmitter；Universal Asynchronous
Receiver/Transmitter）Communication interface is connected, and has one the respectively when the first fan 11 and the second fan 12 are rotated
One rotating speed S1 and the second rotating speed S2, the first control system 111 of first fan 11 receives first rotating speed S1, then by this
One rotating speed S1 is transmitted to the second control element 121 of the second fan 12.Second control element 121 of second fan 12 passes through one
Signal transmission line connects the monitor speed end 14, and second control element 121 is in addition to receiving first rotating speed S1, and reception should
Second rotating speed S2 of the second control element 121 of the second fan 12.Furthermore, receive the first rotating speed S1's and the second rotating speed S2
Second control element 121 is transmitted to the monitor speed end 14 according to this two rotating speeds logical operation and then one output speed of generation.
Especially to be illustrated, the second control element 121 of second fan 12 is according to the first rotating speed S1 and the second rotating speed
The height of both S2 rotating speeds, is that high rotating speed or the slow-speed of revolution select output speed to be the first rotating speed S1 or second according to use demand
Rotating speed S2.In addition, second control element 121 can also be produced according to the first rotating speed S1 and second rotating speed S2 mean speed
The raw output speed.
It is the inventive method schematic flow sheet please continue to refer to Fig. 2.As illustrated, referring to Fig. 1, method of the invention in the lump
Comprise the following steps：
Step SP1：Drive one first fan and one second fan to rotate and produce one first rotating speed and one second rotating speed.As described above,
Control end 13 provides power to first fan 11 and second fan 12, and then output driving signal drives first fan 11
And second fan 12 rotate.The first fan 11 and the second fan 12 rotated has one first rotating speed S1 and the second rotating speed respectively
S2。
Step SP2：First rotating speed of first fan is transmitted to second fan.As described above, first fan 11 has
One first control element 111, second fan 12 has one second control element 121, and the first control of first fan 11
Element 111 connects the second control element 121 of second fan 12.First control system 111 of first fan 11 is received should
First rotating speed S1, is then transmitted to the second control element 121 of the second fan 12 by the first rotating speed S1.
Step SP3：By producing an output speed after the second fan logical operation first rotating speed and second rotating speed.
As described above, second control element 121 is in addition to receiving first rotating speed S1, and receives the second control member of second fan 12
Second rotating speed S2 of part 121, then the second control element 121 of second fan 12 compare the first rotating speed S1 and this second turn
Fast S2 rotating speed height, and it is transmitted to the monitor speed according to the high or low generation of the rotating speed output speed, then by output speed
End 14.Furthermore, the second control system 121 of second fan 12 can also be according to the first rotating speed S1's and second rotating speed S2
Mean speed produces the output speed, then output speed is transmitted into the monitor speed end 14.
The logical operation flow of second control element 121 will be described in detail below.
As Fig. 3 A represent that the output speed of second control element 121 is that the slow-speed of revolution or the logical operation of mean speed are illustrated
Figure, after second control element 121 receives the first rotating speed S1 and the second rotating speed S2, performs whether step S201 compares rotating speed,
If it is not, then exporting both the first rotating speed S1 and the second rotating speed S2 mean speed.If so, then arriving step S202a compares first turn
Whether fast S1 is more than or equal to second rotating speed S2, if so, then second control element 121 selects the output speed to be the second rotating speed
S2；If it is not, then second control element 121 selects the output speed to be the first rotating speed S1.
Implement another, represent the output speed of second control element 121 for high rotating speed or mean speed such as Fig. 3 B
Logical operation schematic diagram, second control element 121 is received after the first rotating speed S1 and the second rotating speed S2, whether performs step S201
Compare rotating speed, if it is not, then exporting both the first rotating speed S1 and the second rotating speed S2 mean speed.If so, then arriving step S202b ratios
Whether it is less than or equal to second rotating speed S2 compared with the first rotating speed S1, if so, then the second control element 121 selection output speed is
Second rotating speed S2；If it is not, then second control element 121 selects the output speed to be the first rotating speed S1.
Setting and method more than, the second fan 12 rather than biography are delivered to by the first rotating speed S1 of the first fan 11
Monitor speed end 14 is defeated by, then the second control system 121 through the second fan 12 receives the first rotating speed S1 and second turn
Fast S2 is simultaneously after logical operation, and the output speed of the second control system 121 of second fan 12 is to monitor speed end 14, by so
Single line output speed be able to easily monitor the operating conditions of many fans.
Only described above, the only preferably feasible embodiment of the present invention utilizes the above-mentioned method of the present invention, shape such as
Shape, construction, device change for it, should all be contained in the interest field of this case.
