Embodiment
Below with reference to relevant drawings, a kind of fan system according to preferred embodiment of the present invention is described.
As shown in Figure 3, the fan system 3 of first embodiment of the invention comprises a control module 37, an addressed module 38 and a plurality of fan 31～36 (is example with six at this).This control module 37 is electrically connected with described fan 31～36, and transmits a control signal C3 and a call signal A3 to described fan 31～36.In the present embodiment, this control module 37 comprise a micro-control unit (Micro Controller Unit, MCU) or the control unit of other kind.This addressed module 38 is electrically connected with described fan 31～36, and transmits a plurality of address signal I31～I36 to described fan 31～36.
How individually this control module 37 described fan 31～36 of control below will be described.When this control module 37 will be controlled wherein a fan, it transmitted this call signal A3 that should fan and this control signal C3 to described fan 31～36.After each fan 31～36 receives this call signal A3, whether one comparing unit of each fan 31～36 is compared this call signal A3 and this address signal I31～I36 of being received of this addressed module 38 certainly, and controlled by this control signal C3 according to the comparison result decision.Wherein, when comparison result is this address signal I31～I36 when identical with this call signal A3, then this fan is controlled by this control signal C3.Certainly, the present invention does not limit the form of comparison result, makes this fan controlled by this control signal C3, and for example comparison result can be this address signal and this call signal A3 difference certain value, makes this fan controlled by this control signal C3.
Is the example explanation at this with fan 31.After this fan 31 received corresponding this call signal A3, its comparing unit was compared this call signal A3 and this address signal I31, and when comparison result was identical, this fan 31 was controlled by this control signal C3.Yet, because the comparison result of the comparing unit of other fan 32～36 is inequality, so described fan 32～36 is not controlled by this control signal C3.Thus, this control module 37 just can pass through to send the call signal A3 of corresponding different fans, and controls described fan 31～36 individually.
As shown in Figure 4, the fan system 4 of second embodiment of the invention comprises a control module 47, an addressed module 48 and a plurality of fan 41～45 (is example with five at this).This call signal A41～A43 that this control module 47 is sent is the set of number signal.This addressed module 48 comprises a bleeder circuit, and this bleeder circuit has a plurality of resistor R, and a plurality of nodes 481～485 of this bleeder circuit are electrically connected with described fan 41～45 respectively.Address signal I41～the I45 of present embodiment is the analogue signal with different magnitude of voltage.
In the present embodiment, this call signal A41～A43 can have 8 kinds of different variations, can correspond to 8 fans respectively, yet present embodiment only different is changed to example to correspond to described fan 41～45 with 5 kinds.When this control module 47 will be controlled this fan 41, it sent this call signal A41～A43 that should fan 41, for example is [000].After this fan 41 received this call signal A41～A43, this fan 41 was according to this call signal A41～A43 inquiry comparison list and obtain a control value.Afterwards, a comparing unit of this fan 41 is compared this control value and this address signal I41, and controlled by this control signal C4 according to the comparison result decision.At this, this control value and this address signal all are a magnitude of voltage, and comparison result is that two signals are identical.Thus, this control module 47 just can pass through to send the call signal A41～A43 of corresponding different fans, and controls described fan 41～45 individually.
Again as shown in Figure 5, the fan system 5 of third embodiment of the invention comprises a control module 57, an addressed module 58 and a plurality of fan 51～53 (is example with three at this).This call signal A51～A53 that this control module 57 of present embodiment is sent is the set of number signal.This addressed module 58 comprises a micro-control unit, and it transmits an address signal I51～I53, also is the set of number signal at this this address signal I51～I53.
In the present embodiment, this address signal I51～I53 can have 8 kinds of different variations, and certainly, present embodiment only different is changed to example to correspond to described fan 51～53 with 3 kinds.In addition, this call signal A51～A53 also can have 8 kinds of different variations, can correspond to 8 fans respectively, and certainly, present embodiment also only different is changed to example to correspond to described fan 51～53 with 3 kinds.In the present embodiment, described fan 51～53 is set at when this call signal A5 and this address signal I51～I 53 are identical, and described fan 51～53 can be controlled by this control signal C5.For instance, this address signal I51～I53 of this fan 51 is [110], then when this control module 57 will be controlled this fan 51, only need be transmitted as this call signal A51～A53 of [110], can control this fan 51 according to this control signal C5.This control module 57 just can pass through to send the call signal A51～A53 of corresponding different fans thus, and controls described fan 51～53 individually.
In sum, a plurality of fans in the fan system of the present invention are controlled by a control signal respectively according to a plurality of address signals and a call signal.Compared to the prior art, the present invention only can control respectively described fan by a control module and an addressed module, and then can effectively control cost, and increases the application of this fan system.
The above only is an illustrative, and and in order to limit the present invention.Anyly do not break away from spirit of the present invention and scope, and, all should be contained in the claim of the present invention its equivalent modifications of carrying out or change.
