Abstract:
Based on ADuC7026, an accurate data converter, a fast dynam icw e ighing sensor is designed. Thewho le system adopts upper com puter and subordinate com pute r, between wh ich Pro to co lRS-232 is used. The subo rd inate compu-t e r ( sensor) is ma in ly used to accom plish amp lify ing signa ls, A /D conversion, data co llection, processing, and transm ission. The upper computer ( com pute r) uses V isua l C+ + to design a g raph ica l use r in terface, wh ich is used fo r parame ter setting and da ta rece iv ing. H av ing introduced the hardwa re com ponents and softw are design, a new data processing m ethod-trigger function is propo sed, and fo r the character istics o f dynam ic we igh ing, the corresponding program flow chart is g iven. Fina lly, a graph ica l user inte rface is introduced s imp ly, wh ich is based onM FC. The system has such advantages: sim ple c ircuit, stab le wo rking , h igh accuracy and alignm ent to se t param ete r, and thus has a good develop ing foreg round.
