IOT APPLICATION IN CONTROL SYSTEM USING WIRELESS SENSOR FUSION

Tóm tắt

A wireless controller based on data fusion algorithm and IoT technology is designed and applied for an active QZS isolator. Firstly, an IoT sensor modular using wireless instead of wired connection is proposed. The wireless sensors of acceleration, velocity and distance are used in the active QZS isolator in order to eliminate unpredictable disturbance causing by wire of sensors. Secondly, the data fusion algorithm embedded in wireless sensor module is described to show how to combine acceleration, velocity and distance data into one kind of information. The fuser with advanced fusion technique will protect control system from a suddenly disabled sensor. Lastly, the system controller uses data fusion to compute control signal for producing a governing force of the isolator. The experiment result shows out 60% better eliminating vibration of the proposed controller.
