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.
Highlights
As the demand analysis for services in the global economy shows, logistics has been one of the most stably growing economic areas since 2008, increasing by an average of 1.13.7% per year. This is true for the rate of development of international and regional logistics: especially high dynamics is observed in the areas connecting the central regions of Russia, as well as in the areas connecting the regional centers of Russia with the logistics centers of China and European countries
The main criterion that tightens the transportation requirements is the amount of cargo weight acting on the trailer chassis and weight distribution along each axis
Many developers offer various technical solutions implemented in the form of automatic on-board weight control systems containing straingauge elements fixed between the chassis and the frame of the trailer’s filled tank [3]
Summary
As the demand analysis for services in the global economy shows, logistics has been one of the most stably growing economic areas since 2008, increasing by an average of 1.13.7% per year. Many developers offer various technical solutions implemented in the form of automatic on-board weight control systems containing straingauge elements fixed between the chassis and the frame of the trailer’s filled tank [3] As such technologies for cargo batching are being developed, the principle of weighing transported materials on board a vehicle has become widely used in the construction industry for making sand and gravel mixtures of exact proportions, sand and cement mixtures, etc. It is worth noting that the introduction of automatic systems operating in an autonomous mode, including on-board weight control systems, requires taking into account the technological features of loading materials [6] These features largely determine the probability of error in their filling. The presented study aims at determining the efficiency of the on-board weight control system using an example of the technological process of preparing the feed mixture
