Fig. 2 is the circuit diagram of the better embodiment of fan detector of the present invention.
Main element symbol description
Following detailed description of the invention will further illustrate the present invention in conjunction with above-mentioned accompanying drawing.
Detailed description of the invention
Below in conjunction with the accompanying drawings and the present invention is described in further detail by better embodiment:
Refer to Fig. 1, the better embodiment of fan detector of the present invention includes that the vibrator circuit 50, that a fan circuit 10, comprising some fans comprises some vibrators 500 receives the controller circuitry 20 and of the rate signal of each fan transmission and the vibration signal of each vibrator 500 transmission for indicating operation irregularity indicating circuit 30 and the fan vibration condition indication circuit 40 of the running status of each fan 100.
Refer to Fig. 2, each fan includes that four pin 1-4, the power pins 1 of each fan 10 are used for being connected to a power supply P5V, and speed pin 2 is by a resistance output speed signal, grounding pin 3 ground connection, and pulse pin 4 is for receiving a pulse signal.In present embodiment, this fan circuit 10 includes first to fourth fan 100-103.
This vibrator circuit 50 includes the vibrator corresponding to this number of fans, and the most each vibrator 500 is for the running status of sensing one fan, and exports the vibration signal of correspondence.In present embodiment, this vibrator circuit 50 includes first to fourth vibrator 500-503, and this first to fourth vibrator 500-503 is respectively used to sense the running status of first to fourth fan 100-103.This first vibrator 500 i.e. is arranged at the installation site of this first fan 100, this first vibrator 500 is for sensing the running status of this first fan 100, as when this first fan 100 runs, this first fan 100 then can vibrate, therefore this first vibrator 500 then can sense the running status of this first fan 100, and exports the vibration signal of correspondence.Installation site and the operation principle of other vibrators are identical with this first fan 100, therefore, repeat in this difference.
This controller circuitry 20 includes a controller chip U1, the pin RA0-RA3(fan of this controller chip U1 connects pin) it is connected to the speed pin of this first to fourth fan 100-103 respectively by resistance R2-R5, to receive the rate signal that corresponding fan exports.If the speed pin of this first fan 100 is by resistance R2 output speed signal to this pin RA0；The speed pin of this second fan 101 is by resistance R3 output speed signal to this pin RA1；The speed pin of this three fan 102 is by resistance R4 output speed signal to this pin RA2；The speed pin of the 4th fan 103 is by resistance R5 output speed signal to this pin RA3.
The pin RC4-RC7(vibrator of this controller chip U1 connects pin) it is connected with a vibrator 500 respectively, for receiving the vibration signal of vibrator 500 output of correspondence.
The pin RC0-RC3(vibration detecting pin of this controller chip U1) it is connected by the negative electrode of resistance R10-R13 and four light emitting diode D5-D8 of this operation irregularity indicating circuit 30 respectively, the anode of this light emitting diode D5-D8 is all connected with this power supply P5V.In present embodiment, according to the vibration signal that each vibrator 500 exports, this controller chip U1 judges that the fan of correspondence is the most out of service, when corresponding fan complete out of service time, this controller chip U1 is by the negative electrode of the vibration signal of corresponding vibration detecting pin output low level to respective leds, to indicate this fan the most out of service, the most just can take off.As when judge this first fan 100 the most complete out of service time, the pin RC4 of this controller chip U1 obtains the vibration signal of corresponding vibrator 500 output, to judge that this first fan 100 is the most out of service according to this vibration signal.When judge this first fan 100 the most complete out of service time, this controller chip U1 then exports this low level vibration signal by pin RC0, so that this light emitting diode D5 is luminous.When judging that the first corresponding fan 100 is in running status, this controller chip U1 then exports the vibration signal of high level and detects pin to corresponding vibration, so that this light emitting diode D5 is the most luminous.When this first fan 100 is in running status, this controller chip U1 then exports the vibration signal of this high level by pin RC0, so that this light emitting diode D5 is the most luminous, and then indicates this first fan 100 not to be removed.
The pin RB1-RB4(of this controller chip U1 runs detecting pin) it is connected by the negative electrode of resistance R6-R9 and four light emitting diode D1-D4 of this fan vibration condition indication circuit 40 respectively, the anode of this light emitting diode D1-D4 is all connected with this power supply P5V.In present embodiment, this controller chip U1 judges the fan whether operation irregularity of correspondence according to the rate signal that each fan exports, when corresponding fan work exception, this controller chip U1 is by the corresponding run signal negative electrode to respective leds running detecting pin output low level, to indicate this fan abnormal.As when the rotating speed judging this first fan 100 is the most abnormal, the pin RA0 of this controller chip U1 obtains the rate signal of this first fan 100 output, to judge that this first fan 100 is the most abnormal according to this rate signal.When judging that this first fan 100 is abnormal, this controller chip U1 then exports this low level run signal by pin RB1, so that this light emitting diode D1 is luminous, to indicate this first fan 100 abnormal.When this first fan 100 is working properly, this controller chip U1 is by the run signal of this pin RB1 output high level to this light emitting diode D1, and D1 is the most luminous for this light emitting diode.
In present embodiment, power pins VPP of this controller chip U1 is connected with this power supply P5V by a resistance R1, and power pins VDD is connected with this power supply P5V, grounding pin VSS1 and VSS2 ground connection.
By vibrator, said fans detector judges that the fan of correspondence is the most out of service, and corresponding lumination of light emitting diode is controlled when fan is out of service, to indicate this fan the most out of service, so avoid and when fan runs, it is taken off by force, operator may be caused the deficiency of certain injury risk.It addition, whether this fan detector occurs exception also by the fan that corresponding light emitting diode instruction is corresponding, user is facilitated to determine abnormal fan.
