Abstract

Materials genome engineering (MGE) integrates high-throughput experiments, high-throughput computations, databases, and artificial intelligence to accelerate the development of advanced materials. However, a reliable and effective method to acquire data from experimental equipment is yet to be identified in MGE. Because the calibration data of high-precision data acquisition systems are not synchronized in terms of time, a linear model is used in this study as a model for data processing parameters, and the value displayed by the device is used as the real value to construct the objective function to optimize the data processing parameters. The Jaya optimization algorithm is used to realize the optimization search of processing parameters. Based on the data acquisition of the equipment temperature as an example, a high-precision data acquisition system is constructed and verified experimentally. The experimental results show that using the optimized model parameters, the average error of data acquisition is only 0.13 $^\circ$C, and the maximum accuracy is 99.89%. Compared with the non-optimized model parameters, the average error reduced by 63.20%, which significantly improves the data acquisition accuracy.
