Abstract

Industrial wireless is essential to achieve the vision of future manufacturing systems which are highly dynamic and reconfigurable, and communicate large amounts of data. Main challenges of wireless deployment include the stochastic nature of the wireless channels and the harsh industrial transmission environment. In this work, a typical two-dimensional gantry system is controlled by a local controller which receives G-code commands wirelessly over a Wi-Fi network. The industrial wireless channel is replicated using a radio frequency (RF) channel emulator where various scenarios are considered and various wireless channel parameters are studied. The movement of the gantry system tool is tracked using a vision tracking system to quantify the impact of the wireless channel on the system performance. Numerical results are presented including the total run time of an industrial process and the dwell times at various positions through the process.
