Implementation of a mathematical component in the device development for operational control of the dump truck

Purpose. To create a device for weighing mining rock loaded into the body of a dump truck after each cycle of its excavation. To develop a mathematical block for calculating the net mass of the rock without taking into account extraneous factors affecting the accuracy of the obtained result. To provide operational control of the nominal load of the dump truck by the driver and excavator operator. Methodology. The methodological basis for solving the task is a comprehensive approach which includes electronic modeling of technical processes, methods of mathematical statistics, analysis of results in a mathematical package and their applied application. Findings. A functional and principled electrical diagram of the device for weighing the mining rock loaded into the body of a dump truck and transferring the final information to this excavator has been compiled. A mathematical block of the device was created, capable of memorizing the signals received from the primary information sensors before weighing, and subtracting them from the signals received from these sensors after each weighing cycle. As sensors of primary information, it is proposed to use selsyns, which are part of the transformer mode, which are mass-produced by the industry, reliable in operation and easy to maintain. Originality. The proposed device is made at the level of the invention; its priority is determined by the constructive development and technical solution. Namely, the device is equipped with a multistable memory transformer, to the erasing winding of which a tachogenerator (or tachometer generator) is connected through an amplifier, a chain of series-connected trigger, multivibrator waiting and key, whose output is connected to the recording winding of the multistable memory transformer, as well as the transformer connected to the input winding of the multistable memory transformer. Moreover, the storage capacitor is connected to one of the key inputs, and the input windings of the transformer are connected to the weight sensor. Practical value. The use of the presented device allows for operational control of the nominal load of the dump truck, objective accounting of transported cargo and realized labor costs, as well as for applying optimal maintenance of cargo and transport works in quarries. In the future, this device will form the basis of a radio telemetry system for dispatching the operation of dump trucks.
