Multi-Opponent Model of Weighing Used in Up-stream Equipment Weighing System

To overcome the defects of involute single spiral transmitter, which has a long time weighing and beyond the permissible error easily, we designed a double helix differential quantitative transmission system as the main structure of the up-stream equipment for automatic weighing and pushing of materials, the equipment used the spiral data acquisition-control device that the main core is Sigma-Delta ADC (Sigma-Delta Analog-to-Digital Converter) and multi-component extraction model weighing algorithm, having a digital filter and characteristics analysis for the weight value, filter out the impact component from the weight information and add estimated aloft value to compensate aloft component. Shortening the time of weighing and increasing the weighing accuracy extremely through control precision grade of millisecond, prolonged failure-free operation of automatic weighing equipment, meanwhile, satisfied the requirements of all kinds of rubber tire production process.
