AI Technical Summary

Problems solved by technology

At present, during the model test, the wave flow control system and the data acquisition system work independently. During the experiment, the staff often choose the start time and stop time of data acquisition based on experience, which will lead to a large amount of redundant data in the later data analysis. , which poses a big problem for the analysis

In addition, due to the different specifications of the instruments during the experiment, it is difficult to synchronize the work of all instruments. This problem causes the data collected by each instrument to have its own clock attribute, and it is difficult to analyze the data in the subsequent analysis. align

In addition, various instruments lacking integrated control are placed in various locations in the laboratory, and the on-site cables are chaotic, which may easily lead to safety incidents
