Title:
METHOD AND DEVICE FOR ANALYZING ELECTRIC POWER CONSUMPTION
Document Type and Number:
Japanese Patent JP3188862
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To make clear the relation of a power control signal and power consumption by detecting the change of the power control signal, storing it in a storage device, periodically measuring a signal concerning the power consumption of the components of a prescribed computer and signal concerning the power consumption of the entire computer and storing them in the storage device.
SOLUTION: A power control signal 123 and a power signal 125 of a computer 100 as an object to be checked are inputted to an analyzer 113, the power control signal is monitored at every timing of a timer of the analyzer 113, and the change of the power control signal is recorded. Similarly, the power signal is monitored at every timing of the timer, and the power consumption is recorded. A memory 117 records data from a signal monitor 115, and the contents in the memory 117 are processed by a visualizing processor 119 and displayed on a display device 121. On the display device 121, the change of the power control signal and the change of power consumption are displayed on the same time base or the change of the contents of the power control instruction and the change of power consumption are displayed on the same time base.
