Current and reventant trends bopping cargoes at ports

Abstract

Modern trends in loading and unloading of bulk cargo in ports are directly related to measuring the mass of these cargoes using strain gauge crane scales. Crane scales in ports allow measuring the mass of cargo directly during its lifting, combining lifting and transport operations with weighing. This makes it impossible to transport cargo to stationary platforms, which, in turn, accelerates cargo handling, increases environmental friendliness and automates the process. There are also a number of advantages to using crane scales in ports. This is the prevention of crane overloading, breakage of slings and direct crane breakage, less damage to the cargo. Mass data is transmitted directly to the display and over a distance to the necessary accounting departments of the port. The complexity of the operation of crane scales lies in the fact that it is necessary to ensure high measurement accuracy in a short time in conditions of cargo oscillation on the crane, vibrations, shocks, etc. The article considers a method for increasing the accuracy of mass measurement on crane scales. To improve the measurement results, an algorithm for processing the signal of strain gauges by an analog-to-digital converter is proposed, which is part of the crane scales, converts the analog signal into a digital code and transmits it as a measurement result.
