Method of Ensuring the Noise Immunity at Measurement of Single-Board Microcontroller Average Energy Within IoT Environment

摘要

This paper is dedicated to developing the methods providing a high accuracy for the system of measuring the average energy of the microcontrollers, microprocessors and single-board computers or single-board microcontrollers (MC) in executing instructions, commands or parts of code. The proposed method of measuring the average energy of the microcontroller is based on the method of measuring the MC instantaneous power. Block diagram and functional diagram of system for measuring the MC average energy consumption are described. The method of improving the noise immunity of measuring the MC average energy is proposed and conditions for its running are formed. The method provides the immunity of the system to the interference impact of the normal mode noise. To implement this method the hardware components are introduced into the system circuit and they are specified. The implemented methods and the developed LabView software simulator are shown as part of information measuring system of average power consumption of microcontrollers. Conducted simulation studies confirmed an ability of proposed methods for precision measurements of MC energy consumption.
