Problems solved by technology
[0009] However, the above-mentioned prior art actually has its problems, because the processing unit 12 needs to increase a pin position for receiving the in-position signal, and the control circuit board 10 needs to increase a detection unit, and the fan 17 needs to increase an external connection terminal. Bit signal terminal 173, for the control circuit board 10, in response to the increased pins of the processing unit 12 and the increased detection unit, the circuit control board 10 needs to increase the circuit layout space for these increased pins and units, and the manufacturing process And the product area will increase, and adding an external terminal to the fan will also increase the process, and these factors will increase the cost and increase the volume of the product

Embodiment Construction
[0053] The above-mentioned purpose of the present invention and its structural and functional characteristics will be described according to the preferred embodiments of the accompanying drawings.
[0054] see image 3 It is a schematic block diagram of the detection device of the present invention, as shown in the figure, it includes a detection module 20 connected to at least one fan 30 . The fan 30 has a power positive terminal 31 , a power negative terminal 32 , a speed control terminal 33 and a speed feedback terminal 34 . The positive terminal 31 of the power supply and the negative terminal 32 of the power supply are used for power input, so as to provide energy for the operation of the fan 30 . The speed control terminal 33 is used for inputting a speed control signal to drive the fan and control its speed. The rotational speed feedback terminal 34 is to provide a fan rotational speed signal generated when the fan 30 actually operates and output to the external detec...

The invention discloses a detection module for fan connection and disconnection states, a device and a system thereof. The detection module is connected with a fan and a host machine respectively. The fan is provided with four external connection ends for connecting the detection module, wherein one rotating speed control end is used for transmitting a detection signal provided by the detection module and a rotating speed control signal; another rotating speed feedback end is used for feeding the detection signal and a fan rotating speed signal back to the detection module from the fan. The host machine is used for judging whether the fan is connected with the detection module or not according to the reception of the detection signal returned from the fan.
Description
technical field [0001] The invention belongs to a detection module, device and system for connecting and disconnecting states of a fan, in particular to a detection module, device and system for detecting whether a fan is connected to a control circuit board. Background technique [0002] Generally, a plurality of computers are placed in a computer room, and these computers will generate a large amount of heat during operation. In order to maintain these computers in a certain temperature condition, multiple fan devices will be set in the computer room to dissipate heat from the computers. The fan module includes a control circuit board connected with a plurality of fans. [0003] Since the computer room generally adopts closed management and is unattended, it is necessary to connect the remote servo device to the control circuit board of the fan module to monitor and judge the connection and operation status of these fans. [0004] At present, most fans are designed with f...
