Application Example of Integrated Data Acquisition System to Effect Evaluation of Labor-saving Agricultural Work by Introducing Assist Suit

In this paper, it is described the example of using the integrated data collection system developed by the authors in an evaluation demonstration experiment of the labor-saving effect of agricultural work by wearing an assist suit. The first author has been requested by Kumamoto Prefectural Agricultural Research Center Production Environment Research Institute to carry out the contracted research from December 2020 to March 2021. As part of the test research project "Evaluation of the effect of labor‐ saving agricultural work by introducing assist suits in Reiwa 2 (2020)", the degree of autonomic nerve activity and muscle activity are investigated using dedicated equipment, and to quantify the effect of labor‐saving agricultural work by wearing an assist suit is the purpose. In order to evaluate the labor-saving effect, "stress evaluation by autonomic nerves", "reduction rate of muscle activity" and "motion analysis by a video" are required, and as measuring devices, heart rate sensor, EMG sensor, and video camera are used. However, since the various measuring instruments owned by the authors are separate systems, it is impossible to synchronously acquire the respective data. Therefore, it is very burdensome for the analyst to manually adjust the acquisition timing of each data after the experiment is completed, and it is difficult to perform perfect synchronization. Therefore, it is reported to be able to facilitate the acquisition of data for demonstration experiments by using the system the authors developed.
