Description
Technical field:
The present invention relates to a kind of method and device thereof that obtains information monitored by main board, be meant a kind of I that solidifies by computer motherboard or rather
2The C bus reads the method and the device thereof of information monitored by main board.
Background technology:
Along with the continuous progress of computer industry level, people have proposed more and more higher requirement to performance, stability and the reliability of computing machine.To the endless pursuit of computing power, make present computing machine core component---the frequency of operation of central processing unit (being CPU) is more and more higher, the operating rate of the peripheral components of auxiliary work such as mainboard, hard disk etc. also constantly increases with it.The inevitable outcome of this technological trend is exactly: the power that these parts consumed is constantly increasing, and thermal value is also increasing, and the crash rate of the parts of working under this condition for a long time also is index and rises.For guaranteeing the stability and the reliability of complete machine work, just require these parts and be the peripheral components of these parts services, have higher reliability as power supply etc.
The method that improves part reliability has multiple, except improving the technology content of parts, improve beyond the production technology, if can be to the correlation parameter of these parts---voltage, temperature, rotation speeds of the fan etc. are monitored in real time, take place in time to provide warning when unusual in these parameters, the user can in time be intervened, then undoubtedly can prevent these parts to a great extent owing to be in abnormal operating state for a long time because of exceeding normal working voltage, the inefficacy that normal working temperature causes, thereby can significantly improve the job stability and the reliability of complete machine, prolong the serviceable life of parts and complete machine.
Referring to Fig. 1, at present, there has been the obtain manner of multiple hardwares monitor message, wherein modal way is to read the hardware sensor information that the integrated hardware monitoring chip of mainboard is obtained.
