| Popis: | With increased automation in the manufacturing industry, the demand for a quick and accurate mass measurement system is growing. Currently, an active belt conveyer is in demand by many enterprises. However, there is a problem that the active belt conveyer causes mechanical noises. The main noises are three kinds, which are the natural oscillation of measurement conveyer, oscillation by rotation of motor and belt pulley. They cause observable signals within the active belt environment. Therefore, we have to remove those noises to acquire a greater accuracy. In the current mass measurement system, the moving average method is used to remove those noises. Unfortunately, it is not able in the current system to give a method for more quick and accurate measurements. In this paper, we propose a frequency analysis method using the LMS algorithm. Moreover, we develop the system using this method and the moving average method. Finally, we use a device actually marketed in order to verify the utility of the system by comparative experiment between current system and proposed system. |
