Sensing method and system for analyzing working state of intelligent terminal through current

Abstract

The invention discloses a sensing method and system for analyzing the working state of an intelligent terminal through current. The method comprises the following steps: adopting floating point data with preset precision to represent the current value, obtained in real time, of a programmable power supply; forming the floating point data into a time sequence data stream according to a preset time sequence rule; performing Kalman filtering processing on the time sequence data stream; identifying the current by adopting a perceptron classification method, and predicting to obtain three states of the tested terminal; and calculating the average current and the standard current in each state and comparing the average current and the standard current to judge the electric leakage conditions in the three states. The invention has the advantages that: prediction of three basic states including shutdown current and state, startup current and state and standby current and state can be achieved, whether the mainboard leaks electricity in the three states or not is judged, errors caused by manual test of current data are avoided, the labor capacity and operation complexity of production line workers are reduced, the production line efficiency and accuracy are improved, and the yield of products is improved.

Description

Technical field [0001] The present invention relates to the field of intelligent terminal manufacturing techniques, and in particular, a perception method and system for analyzing the operating state of the intelligent terminal by current. Background technique [0002] With the development of technology, intelligent terminals, especially smartphones, have become a necessary product, which promotes communication between people, and also enriches people's daily lives. Due to the way the smart terminal is powered, it is extremely important in reducing the power consumption of intelligent terminals, extending its battery ability. [0003] Today's tablet, mobile phones, etc. are mostly based on Android, Linux system, because they are based on battery power supply, one or even a few days, so it is very strict in power management. Once the component is broken, or the welding short circuit, the leakage is caused, resulting in high operating current, the battery consumption is too fast, a...
