With the continuous improvement of server performance, its power consumption be also it is constantly soaring, for environmental requirement increasingly it is urgent instantly, service
The efficiency of device just particularly important, usual server has a controlling mechanisms of various raising system effectivenesies, but what these were realized
Method is almost required for knowing the total power consumption of system, and it is superfluous that usual mainboard can read hot plug by power management bus PMBUS
The power consumption of remaining power ps U, so as to understand the total power consumption of system.Under PSU redundancy structures, it is necessary to read in turn by PMBUS
The power consumption of each PSU, then the total power consumption that accumulation calculating obtains system is carried out, but this mode is because PMBUS is at each moment
A power consumption of PSU can only be read, so causing last accumulation result to have error, precision is done not high.
In order to ensure security, common PCB supply paths can all do a requirement for safety of 240VA, so common
Design be to want that increasing hot plug circuit carries out current limliting in input path.The hot plug chip of application is typically one at present
Individual controller can only control a path, and this is in more complicated power distribution system, it is necessary to increase many controllers,
And it is separate before each controller, equally there is the problem of the precision of detecting total power consumption as mentioned above.This is existing skill
Weak point existing for art.
The content of the invention
The purpose of the present invention provides a kind of server total power consumption and supervises in real time aiming at the deficiency existing for prior art
Control device and monitoring method, be pooled to the output current of all hot-plug redundant power supplys on precision resistance by the program, and makes
