Data acquisition system was very important for the implementation of intelligent manufacturing electric machines digital factory. For a newenergy vehicle (NEV) electric machine digital factory, with configuration software as the core processing layer, key production parameters such as production equipment parameters, production personnel information, material information and quality data were collected through industrial Ethernet network to construct the exchange of workshop production site comprehensive data. This data acquisition system could provide data support for the upper management system of intelligent manufacturing, realizing the intelligent manufacturing of electric machines.
