Problems solved by technology

But in this way, if there is a big change in the power consumption of the computer under test 73 during the test, for example, when the computer under test 73 executes the test program in step S1.6, the actual power consumption of the computer under test 73 is likely to If the maximum value that can be measured by the gear used by the power meter 72 is exceeded, the power meter 72 will display overflow information at this time, so the power consumption of the computer under test 73 cannot be obtained correctly

Embodiment Construction

[0031] In order to better understand the characteristics of the present invention, a preferred embodiment is provided here and described as follows in conjunction with the accompanying drawings, please refer to Figure 3 to Figure 4 .

[0032] Please refer first image 3 , which is a system architecture diagram for implementing the power measurement method of the present invention. Wherein, both the testing terminal 10 and the tested terminal 40 can be computers or other equivalent computing devices, and the testing terminal 10 can control the AC power supply through interfaces such as but not limited to GPIB, RS232, USB or TCP / IP 20 output voltage and frequency, and provide power to the terminal under test 40 via a power meter (powermeter) 30 .

[0033] In addition, the test terminal 10 can also read, record and analyze various data measured by the power meter 30 through other interfaces, these data include the power consumption of the test terminal 40 measured by the power...

Abstract

The invention provides a power measurement method. A measuring end controls a measured end to enter a test mode, and power of the measured end is measured through a power meter. The power measuring method comprises the following steps: the power meter is set to be in an automatic gear mode to measure the power of the measured end, and the measuring end obtains a power value measured by the power meter. So a suitable gear is automatically adjusted through the automatic gear mode of the power meter, the measuring end is only used to obtain the power value measured by the power meter, and the problem of measurement overflow resulted from a drastic change of power of the measured end in a test process can be prevented.

Description

technical field [0001] The invention relates to a power measurement method, in particular to a method for measuring the power of a computer under test, which can avoid the problem that the power meter overflows when the power of the computer under test changes drastically. Background technique [0002] Since 1992, the U.S. Environmental Protection Agency (EPA) has started to promote the Energy Star Program (EnergyStarProgram), the purpose of which is to reduce the consumption of various energy sources in order to improve the greenhouse effect. Among them, as far as computer products such as desktop computers or workstations are concerned, the power consumption of computer products must be measured in different test modes such as specified software mode (PowerMaxMode), shutdown mode (OffMode), and sleep mode (SleepMode). , so as to determine whether the above-mentioned computer products meet the specifications of the above-mentioned plan. [0003] Please refer to figure 1 T...
