Abstract

The paper presents a synthesis of a microprocessor-based measuring system for the dynamics and energy of mobile machines. It was determined that the measuring systems used to study the operation of cars, tractors and machine-tractor units today are not able to measure many parameters of functioning in dynamics during the execution of technological processes in agriculture. The use of microprocessors changes the structure of the digital part of devices. Significant computing capabilities of microprocessors allow the use of more complex work algorithms. At the same time, the requirements for the analog part of the measuring device are reduced and high metrological and operational characteristics are ensured. Based on the microprocessor, a measuring system was created to determine the dynamic and traction-energy indicators of the functioning of mobile machines. The main element of this system is a computing module consisting of an STM32F407 microprocessor computing element that processes data from sensors and a microprocessor element for data collection and storage. A hard disk, solid-state drive or USB Flash drive is used as an information storage device. The computing module has a touch display for displaying parameters and controlling the measuring system, so it can be used without an external personal computer. The number and types of sensors with which the machine is equipped during testing depends on its type and parameters required for study. To determine the dynamics of the tractor or unit elements, an inertial measuring device is used, consisting of gyroscopes and acceleration sensors, the number of which depends on the number of tested elements. The measuring system of dynamic and energy parameters of tractors and machine-tractor units was used in the study of the KhTZ-242T wheeled tractor. The dependence of the traction force of the seeder and the spectral density was determined. The results of experimental studies proved the effectiveness of using a microprocessor measuring system during field and laboratory tests of tractors and machine-tractor units.

Keywords: microprocessor, measuring system, tractor, experimental studies.
