Embodiment Construction
[0030] A fan system and its control device according to a preferred embodiment of the present invention will be described below with reference to related drawings.
[0031] see figure 2 As shown, a control device 20 of a fan system according to a preferred embodiment of the present invention can be used in cooperation with an external system 2 , and the fan system has at least one fan 3 . The control device 20 receives a starting voltage 91 and a warning signal 92 . Wherein, the starting voltage 91 is provided by an external voltage source V, and the control device 20 starts to act after receiving the starting voltage 91 . The control device 20 includes a start control unit 21 , a drive unit 22 and a speed control unit 23 .
[0032] When receiving the start voltage 91, the start control unit 21 generates a start control signal 93, the start control signal 93 in this embodiment can be a high potential signal, and after a predetermined time, the start control unit 21 stops se...
