Research of Dynamic Weighing System Based on Multi-sensor Data Fusion Technology

The method of data fusion is used on the weight-data which is measured by the ultrasonic sensors, speed sensors, capacitive sensors and weighing sensor. The multi-sensor integration and data fusion is key technology for in- creasing the measuring precision of the weighing system. It can obtain the materials data which has the high anti-disturb- ance ability and high accuracy. Simulation results show that the method is superior to ordinary processing methods in the data processing accuracy and robustness. Consequently, it can effectively reduce environment factors such as the noise, vibration, electromagnetic interference on the dynamic weighing system measurement.
