Embodiment
For setting forth thought of the present invention and purpose, will combine accompanying drawing and specific embodiment that the present invention is done further explanation below.
The present invention is to provide a kind of mobile phone current anomaly testing circuit and method, be primarily aimed at smart mobile phone in use, a plurality of program run that often occur occupy a large amount of battery electric quantities, and cause the problem that shortens in serviceable life of battery of mobile phone.
See also shown in Figure 1ly, Fig. 1 is circuit theory diagrams of the present invention.This mobile phone current anomaly testing circuit wherein; Include mobile phone CPU and battery, connect through the mobile phone feed circuit between said CPU and the battery, and be provided with a detection resistance in these feed circuit; The electric current of battery output is input to CPU through this detection resistance; Also be connected with voltage dependent resistor (VDR) and electric capacity of voltage regulation on the said battery, and through voltage dependent resistor (VDR) and electric capacity of voltage regulation ground connection, to reach the purpose of stable cell voltage.
Wherein the two ends of this detection resistance are connected with an analog to digital converter testing circuit; Said analog to digital converter testing circuit ADC+/ADC-is mainly used in the voltage that detects said detection resistance two ends; And the result that will detect issues CPU; And CPU calculates through detecting the electric current of resistance through I=V/R, promptly obtains the battery consumption current value of this moment.
Principle of work of the present invention is: detect resistance through having increased by one in the normal power supply circuit between battery of mobile phone and mobile phone CPU; Battery is that the electric current of CPU power supply passes through this detection resistance; Utilize the analog to digital converter testing circuit to detect the electric current that passes through this detection resistance under the current phone user mode; And the standard current sinking in this actual consumption electric current and the current data storehouse is compared by CPU; If poor distance surpasses regulation numerical value, represent that then battery current consumption is unusual, to remind the user to close unusual program or to restart.
More than be detailed introduction, will combine Fig. 2 that mobile phone current anomaly detection method of the present invention is done further explanation below mobile phone current anomaly testing circuit of the present invention.
A kind of mobile phone current anomaly detection method comprises step:
