Information and measurement system of traction transport vehicles

Abstract

The synthesis of the information and measurement system for traction transport vehicles was performed in the study. It was established that, depending on the purpose, measuring systems are divided into measurement information systems, measurement control systems, measurement control systems, etc. The majority of tractors produced have analog information and measurement systems. The structure of the information and measurement system was proposed, which includes a microprocessor and the following sensors: inertial measurement device (IMP); tractor speed sensor; engine rotation speed sensor; fuel flow meter. The developed information and measurement system allow to determine the parameters of the tractor's functioning more quickly and the operator may choose effective modes of operation by changing the transmission or speed of movement. Depending on the change of the measuring task, the system is called a flexible measurement system. It is determined that the energy assessment is carried out in order to determine the balance of power and the correctness of the choice of energy means for an agricultural machine or to determine the traction characteristics of a tractor. Experimental models of mounted, semi-mounted and trailed agricultural vehicles and implements in a unit with tractors, as well as self-propelled vehicles that ensure the execution of the work process, or experimental models of vehicles driven by an internal combustion engine or an electric motor are subject to energy evaluation. During the energy evaluation, the power consumption of the machine-tractor unit is determined in the modes of operation, in which technological operations are performed stably. Energy assessment of agricultural vehicles and implements is carried out on a specially equipped tractor corresponding to the traction class of the tested vehicle or implement. The developed measurement system refers to technical means of diagnosis and operational control and can be used in agriculture and machine-building industry. It is intended to determine the kinematic, dynamic, power and energy characteristics of mobile vehicles and their elements during road, field and bench tests. Key words: measurement system, sensor, energy assessment, tractor.
