Problems solved by technology

[0007] However, the shortcomings of this method are obvious, mainly: 1. Lack of effective monitoring of the status of the power supply fan; 2. When the power supply unit is used as a non-standard component, the cost of the component increases and the material management is complicated, which is not conducive to mass production and introduction
It cannot well meet the safe and stable operation requirements of computer systems

Embodiment Construction

[0038] Attached below Figure 1~3 The device and method for monitoring the status of computer power supply fans of the present invention are further described in detail.

[0039] The present invention adds a rotational speed monitoring device to the existing computer system to monitor the running state of the power supply fan and feed back to the computer system in real time, and the computer system takes follow-up protection measures based on this.

[0040] Such as figure 1 As shown, the device for monitoring the state of the computer power supply fan of the present invention includes a speed sensor 1 connected to the air outlet of the computer power supply, an A / D converter 2, a receiving signal port 3 located on the computer motherboard, and a monitoring control module 4 .

[0041] The speed sensor 1 is used to detect whether the power supply fan rotates to dissipate heat for the computer system during the operation of the computer, and transmits the analog signal of the d...

Abstract

This invention relates to one device and method to monitor computer power fan status, which comprises the following parts: speed sensor connected to computer power exit; A / D converter; receive signal end on computer host board and monitor control module, monitor control module to read fan rotation signal from signal end to judge whether the fan is normal by protection actions of control system.

Description

technical field [0001] The invention relates to the computer field, in particular to a device and method for monitoring the state of a computer power supply fan. Background technique [0002] In modern computer systems, the system power supply (Power Supply) provides the necessary power supply voltage for the computer system. The stability of the computer system is closely related to the stable operation of the power supply. [0003] As an electrical device that directly converts alternating current into direct current, the power supply has a relatively large thermal efficiency, so the heat dissipation requirements of the power supply itself are also very high. The heat dissipation of the power supply is directly completed by the power supply fan. The power supply fan mainly meets the heat dissipation requirements of the power supply and also provides the cooling requirements of the system (such as: heat dissipation of the graphics card). Therefore, to some extent, whether...
