Problems solved by technology

Therefore, the added hardware monitoring controller 120 not only takes up extra motherboard space, but also leaves the remaining fan control pins unused and wasted.
Therefore, there are still many deficiencies in the existing fan control system and it is necessary to improve it.

Embodiment Construction

[0017] figure 2 It is a block diagram of a complex signal processing system with multiple fans in the present invention, the system includes a first fan 210, a second fan 220, a logic gate 230, a hardware monitor controller (hardware monitor) 240, and a control device 250 And a warning device 260 .

[0018] The first fan 210 and the second fan 220 have control pins 211 , 221 and output pins 212 , 222 respectively. The control pins 211, 221 receive a control signal PWM4 to drive and control the speed of the first fan 210 and the second fan 220, and the output pins 212, 222 output a signal representing the speed of the first fan 210 and the second fan 220. speed signal. The first fan 210 and the second fan 220 are preferably fans with the same rated speed, that is, the two fans have the same maximum average speed under the same control environment.

[0019] The first input end 231 of the logic gate 230 is connected to the output pin 212 of the first fan, and the second input...

Abstract

A composite signal processing system of a multiple fan is provided, which is used for controlling operation of at least a first fan and a second fan, after the speed signal of the first fan and the speed signal of the second fan are calculated by a XOR, a composite speed signal can be generated. According to the composite speed signal, the speed of the first fan and the second fan can be worked out and whether the operation is normal can be judged.

Description

【Technical field】 [0001] The invention relates to the technical field of heat dissipation of electronic products, in particular to a composite signal processing system and method of multiple fans. 【Background technique】 [0002] Recently, due to the rapid progress of semiconductor technology, not only the number of transistors in the same integrated circuit (IC) is increased, but also the execution timing of the integrated circuit is improved. In this way, related electronic products can improve execution speed and add many functions. Due to the rapid increase in the number of transistors in integrated circuits and the improvement in execution timing, the heat dissipation of electronic products has become an urgent problem to be solved. [0003] figure 1 is a schematic diagram of an existing fan control module. The hardware monitor controller (hardware monitor) 110 utilizes the TACH1~4 pins to receive and process the fan speed signal (tachometer signal). The hardware mon...
