Embodiment
Below in conjunction with the drawings and specific embodiments, the invention will be further described.
The invention provides a kind of method for measurement realizing main board system multichannel VR real time power consumption, as shown in Figure 1, its specific implementation process is:
Adopt data acquisition unit to access the multichannel VR of mainboard simultaneously, every road VR is all connected with data acquisition unit two-way, a road is for measuring electric current, and a road is used for measuring voltage, then the electric current obtained and voltage is done the input power consumption that product obtains this group VR.
The input supply path of every road VR all connects a precision resistance R, the circuit that data acquisition unit is connected with this road VR is specially:
The positive pole of the slotted line of a data acquisition unit passage and negative pole are connected on respectively input end and the output terminal of precision resistance, the data that this channel measurement line obtains, divided by the resistance of precision resistance, can obtain input current; The positive pole of the slotted line of another passage and negative pole are connected on respectively input end and the mainboard ground of precision resistance, the data that this channel measurement line obtains are input voltage again;
Other VR on mainboard is adopted identical connected mode successively, measures its input power consumption.
Described data acquisition unit also connects computer terminal and communication by RS-232 cable, and the image data of this data acquisition unit is uploaded to computer terminal by RS232 bus, and processes data on computers.
Embodiment: for clearly setting forth innovative point herein, to measure 6 road VR(DDR:AB, CD, EF, GH4 road, also have CPU0 and CPU12 road) be example in the input power consumption in main board system work a certain moment.
As shown in Figure 1, there is a precision resistance R 6 VR front ends, road, and direction of current as shown in Figure 1.For measuring the power consumption of this 6 road VR, traditional method of testing is: (for AB) uses the pressure reduction at multimeter precise engineering surveying resistance R two ends.And precision resistance value is fixing (precision resistance value is very little by the impact of temperature, and when the electric current flow through is very large, resistance value also can be considered fixing).
Like this, the input voltage of measurement, divided by resistance, can obtain the electric current flowing through precision resistance, namely the input current of this group VR; Then, measure the voltage-to-ground of precision resistance front end, the input voltage of this group VR can be obtained.Be multiplied by input current with input voltage like this, just can obtain the input power consumption of this group VR.Finally, adopt similar method, then remove the input voltage measuring other 5 tunnels respectively, input current value, just can obtain the input power consumption number of 6 groups of VR corresponding to synchronization.
Although classic method can measure power consumption number, there is following weak point:
1), the voltage at precision resistance two ends is usually smaller, and multimeter usually used is difficult to measure accurately by measuring accuracy restriction, affects test accuracy;
2), owing to singly can only organize measurement, 6 road VR, need measurement 6 times, waste time and energy;
3), due to 1 road VR once can only be measured, the power consumption of 6 road VR at synchronization cannot be obtained, namely can not obtain 6 road VR real time power consumptions.
For improving this method of testing, method of the present invention is adopted to test, as shown in accompanying drawing 2, Fig. 3, use data acquisition unit instead to go to measure, each road VR, gather precision resistance both end voltage with two data acquisition channel: CH1, input current (pressure reduction is divided by precision resistance resistance) can be obtained, CH2 Gather and input voltage.Like this, the input power consumption of this road VR can be obtained.
In like manner, adopt other 10 circuit-switched data acquisition channel to gather remaining 5 road VR respectively, the power consumption that other 5 road VR is corresponding can be obtained.Because data acquisition unit can gather multiple passage simultaneously, the input power consumption of 6 road VR, can realize reading simultaneously.
Finally, as shown in Figure 3, with RS-232, data acquisition unit and computer terminal are coupled together, in order to communication; Image data is uploaded to computer terminal by RS232 bus, and processes data on computers.
Above-mentioned embodiment is only concrete case of the present invention; scope of patent protection of the present invention includes but not limited to above-mentioned embodiment; any according to the invention a kind of realize claims of the method for measurement of main board system multichannel VR real time power consumption and the those of ordinary skill of any described technical field to its suitable change done or replacement, all should fall into scope of patent protection of the present invention.
