Description

technical field [0001] The invention relates to the field of electronic equipment testing, in particular to a low-power consumption electronic equipment testing method, a low-power consumption POS terminal testing method and a device. Background technique [0002] With the continuous development of science and technology, the requirements for low power performance of electronic equipment are becoming more and more stringent, especially for POS terminals, which have strict requirements for low power performance. It can reduce the heat dissipation of the POS terminal and improve the stability and reliability of the equipment. Factors affecting system power consumption include CPU clock, GPIO, power supply, peripherals, software system, etc. According to the power formula W=UI, under stable voltage conditions, the smaller the system current, the lower the power consumption. Through the software system control, enter the CPU stop / sleep mode, turn off some clock signals, the po...

AI Technical Summary

Problems solved by technology

[0003] However, for the testing of low-power electronic equipment, especially the low-power POS terminal test, in the prototype design stage, the low-power current is estimated based on theory, and there are errors

At the same time, there are many factors that affect low power consumption. In actual mass production, manually testing, recording, and counting low power consumption current values ​​one by one is time-consuming, laborious, low work efficiency, information deviation, and prone to data distortion, resulting in low power consumption performance. poor consistency

Based on the above situation, most of the POS terminal manufacturers currently only conduct low-power sampling tests, and do not conduct 100% full-test tests.
