Abstract

A type of portable signal monitor base on SoC is designed. Peak value sampling method is presented to record uncertain or short time voltage signal symptom of the monitored signal. The method solves the problem that traditional voltage monitoring equipment can not capture subtle changes in the voltage signal. Method of responding to multiple interrupts in single interrupt pin is presented to realize the acquisition of switching value. In this way, the monitor improves the quality of the signal device management and prevents the hidden accident.
