Computer power supply management method based on CPLD

Abstract

The invention provides a computer power supply management method based on a CPLD. The method includes the steps of sending out a system state signal indicator though a system bridge piece to obtain current system information, controlling power supply modules according to the system information, obtaining current system temperature information by means of fan management modules in the CPLD through an I2C bus, and stably controlling the temperature of a main board by adjusting the rotating speeds of fans, thereby achieving power supply management and fan control of a whole computer from the two aspects. According to the computer power supply management method, a CPLD chip is adopted as a main control chip, the multiple power supply modules and the multiple fan management modules are controlled through the chip, hardware design space is saved, the method is high in controllability and flexible in configuration, the product modularized use rate of an enterprise is increased, and production cost is reduced to a certain extent.

Description

technical field [0001] The invention relates to the technical field of computer power supplies, in particular to a CPLD-based computer power supply management method. Background technique [0002] With the continuous development of computer technology, people's demand for computers is also increasing, and people's daily life is increasingly inseparable from intelligent systems such as computers. The increase in demand also makes security issues more prominent, and more and more Computer users began to desire to use autonomous and controllable computers with domestically produced processors and operating systems to avoid various uncontrollable security incidents, especially in special fields involving information security. The demand for autonomous and controllable computers is increasing. wide. [0003] At present, most of the computer systems with foreign processors as the mainstream adopt some standards to realize the compatibility and scalability of their functions, and ...

AI Technical Summary

Problems solved by technology

However, there is a lack of relevant standards in the field of domestic computers. With the continuous application and promotion of domestic processor platforms, the demand for similar power management is also increasing.

And in special fields involving information security, customers usually have special management requirements for computers, and the design of computers is generally based on customer demand indicators. One computer cannot meet different management requirements. The usual solution is to modify the hardware principle. For enterprises, this method is not highly controllable and costly
