Abstract

The study purpose is to determine the operational efficiency of the on-board weight control system using the technological process of preparing the feed mixture as an example. The Daily TMR Manager, an on-board weight control system, consisting of communication components, digital indicators with information on the display installed in the operator’s cab (of the mixer-and-distributor) and loader operator, and the “Feeding Management” software package were used as a means of controlling the technological process of preparing the feed mixture. The recorded data were transmitted via Internet resources to a cloud storage that provides round-the-clock access to information. The process of evaluating the performance of the weighing system involved loading stalky bulk and loose concentrated components of the feed mixture. Analyzing the evaluation results of the weight control protocols with the recorded data, the authors have determined the influence of human-machine interaction on accuracy, and revealed that the material dosing error increases inversely with the dosed material mass. To improve the operational characteristics of on-board weight control systems it is recommended to install weight sensors on the loader boom to reduce the error when dispensing materials and increase the operator’s response speed.
