Problems solved by technology

For general large-scale scientific research experiments, it takes a long time for measurement operation and data recording, and it takes longer time for data sorting, input and analysis calculation processing, such as more than one day, and the work efficiency is low.
In addition, the influence of human errors and changes in environmental conditions during the experiment cannot guarantee the reliability of the experimental data.
