The power lines 161 and 162 and the control line 163 They are electrically connected to the male port 14 and the female port 15 respectively. Among them, one of the two power lines 161 and 162 can be a live line (that is, V+ in the technical field), and the other is a ground line (that is, GND in the technical field), and the control line 163 is used to transmit digital Signal. Furthermore, in the present invention, the male connection port 14 can be disposed on the frame body 11 or extend out of the frame body 11 through a partial line segment of the transmission line group 16. On the other hand, in the present invention, the female port 15 can be disposed on the frame 11 according to the implementation requirements. When the female port 15 is disposed on the frame 11, the female port 15 and the male port 14 Located in this frame One of the four end corners 111 to which 11 belongs is shown in FIG. 1, that is to say, the male connection port 14 and the female connection port 15 are located at different end corners 111 respectively.

Referring again to FIGS. 1 and 2, the power obtaining unit 17 of the present invention connects the two power lines 161 and 162 in parallel, that is to say, whether the power obtaining unit 17 is normal or not does not affect the two power lines 161 and 162 . In one embodiment, the power obtaining unit 17 is composed of two power transmission lines 171, 172, that is to say, the power obtaining unit 17 of the present invention does not necessarily have functions such as power conversion or power stabilization. In addition, the power obtaining unit 17 is electrically connected to the driving unit 122 and the signal processing unit 18 to provide the working power 402 to the driving unit 122 and the signal processing unit 18.

At this time, the two fans 10 and 20 will be linearly arranged, and the frames 11 and 21 of the two fans 10 and 20 are closely connected, as shown in FIGS. 3 and 4. Hereby, when the fan 10 connected to the control source 400 receives the working power 402 and the control signal 401, the working power 402 is divided by the power The obtaining unit 17 inputs the driving unit 122 and the signal processing unit 18 to the other fan 20 via the two power lines 161 and 162, so that the other fan 20 can obtain the working power 402 to work. On the other hand, the control signal 401 is input to the signal processing unit 18 via the control line 163. In addition to inputting the control signal 401 to the driving unit 122, the signal processing unit 18 also passes the received control signal 401 via the The control line 163 is output to the female port 15 to enable the other fan 20 to work based on the control signal 401.

More specifically, when the fan 10 obtains the control signal 401 from the control source 400, the driving unit 122 enters the first mode and operates based on the speed control command included in the control signal 401. Conversely, when the fan 10 fails to obtain the control signal 401 from the control source 400, the drive unit 122 enters the second mode and operates at the preset speed, which is referred to herein as the preset speed The maximum speed or the minimum speed of the motor 123. Furthermore, when the fan 10 is implemented in plural to form the fan system 300, once one of the fans 20 as the connection relationship does not receive the control signal 401 transmitted by the other fan 10, the fan 20 belongs to The driving unit 222 will enter the second mode, so that the motor 223 to which the fan 20 belongs operates at the preset speed.
