Abstract
Investigation of the load on the conveyor structures in extreme situations in order to reduce their action, reduce energy consumption and metal consumption of supporting structures through the introduction of an adaptive speed control system of the belt conveyor. The methods used in the study are developed in the theory of automatic control, processing of random processes. The scientific generalization of previously performed research in the analysis of literature and patent sources is also used. Adaptive speed control of the belt conveyor is offered taking into account the change of load on the supporting structures of the conveyor, which is manifested in the case of transportation of cargo with large pieces of rock mass (up to 500 mm). Improving economic efficiency is achieved by reducing energy consumption and load on supporting structures, which reduces their metal content. Management is due to the coordination of modes of transportation and actual freight flow in the absence of complete a priori (such as known in advance) information about the particle size distribution of raw materials, external perturbations and boundary conditions, ie adaptive system is uncertain. Modern conveyor lines have a long length, so reducing the load on the supporting structures can reduce their metal content by 25 - 30%. Improving the operation of long conveyors requires the development of systems that optimize the mode of their operation on the basis of the minimum load on the supporting structures during the transportation of minerals. Adaptive control of the belt conveyor by adjusting the speed of the working body of the conveyor, taking into account the parameters that are constantly changing, allows to increase the efficiency of production and reduce metal consumption. The authors propose the principles of construction of an automated conveyor system, which differs in that it takes into account both the current and projected state of freight traffic. Timely detection of changes in the composition of the cargo flow allows you to quickly respond to new information and adjust control effects by implementing an adaptive regulator. The introduction of adaptive belt conveyor speed control systems is proposed according to the criterion of reducing the metal content of supporting structures, which allows to take into account the perturbing effects on supports due to changes in the composition of the cargo flow, it reduces the load on them and reduces metal consumption.
