Study on error modification of dynamic weighing system

XIAO Shan,LU Wu-yi,WEI Xiao-hui,JI Yan-ping(Department of Information Science and Engineering,Central South University,Changsha 410075,China)  
An automatic weighing instrument is developed,which can automatically and immediately calculate the weight of material in bucket of a loader.Improving weighing accuracy plays an important role in designing automatic weighing instrument based on the hardware.Therefore,kinds of factors causing errors are discussed,and then elimination method,improved Akima interpolation and other related solving methods are presented.The choke points of the loader's weighing system have been solved,and the weighing accuracy is up to 1 %.Moreover,a simple and feasible debugging method which fits the fieldwork of debugging is put forward.In real operation,it is show that the automatic weighing instrument has some good performances,such as high integration,high weighing accuracy and high reliability.
