Embodiment Construction

[0034] The invention relates to a general control system for fans, which is used for fans with multiple pins. According to the number of pins, it can be roughly divided into two different types: a three-pin fan and a four-pin fan. In the present invention A three-pin fan or a four-pin fan can be used according to the needs of users and system hardware.

[0035] For the fan general control system of the present invention, please refer to figure 1 and figure 2 The three-dimensional schematic diagram of the fan general control system of the present invention is shown, and please also refer to image 3 The schematic diagram of the circuit block.

[0036] The general fan control system of the present invention includes a connector 200 and a processing unit 101 respectively disposed on a motherboard 100 , wherein the processing unit 101 is electrically connected to the connector 200 . The connector 200 is for the three-pin fan 300 or the four-pin fan 400 to be inserted thereon, ...

Abstract

The present invention relates to a fan shape judgment and control method, including firstly electrically inserting a fan to a connector, detecting electric signals of power supply pins, ground connection pins, rotation speed detection pins and rotation speed control pins by a processing unit, determining the electric signals of the rotation speed control pins, generating a first rotation speed control signal to convey to the fan by the power supply pin, or generating a second rotation speed control signal to convey to the fan by the speed control pin.

Description

【Technical field】 [0001] The invention relates to a judging and controlling method and a control system using the method, in particular to an automatic fan type judging and controlling method and a general fan control system using the method. 【Background technique】 [0002] Due to the rapid development of computer technology at present, the amount and speed of calculations of desktop computers, notebook computers, and server hosts are constantly increasing. The waste heat generated by components or devices is also considerable. In order to avoid affecting the operation of computer systems or servers due to overheating, fans are used inside the mainframe to dissipate heat to maintain normal operation. [0003] Generally, the fan is electrically connected to the connector on the main board, so that the computer system supplies power to the fan as a drive, and the rotation speed of the fan is controlled through the electrical connection relationship of the connector. At presen...
