A data analysis system based on MATLAB GUI for portable emission measurement
In terms of vehicle emission research, it is necessary to measure the real-time emission data of vehicle without affecting its normal operation. At present, portable emission measurement system is utilized to obtain vehicle emission parameters accurately under the actual operating conditions. This paper introduces a data analysis system based on MATLAB/GUI for portable emission measurement, which can process and analyze the data gained from each separated measuring unit. Thus the relations of the related parameters are acquired and shown using graphics. Verified by the experiment, this system can meet the requirement of portable emission measurement in respect of the accuracy and speed of data processing.
