Quality control of power transmissions and undercarriage systems using digital technology

Violation of the technical condition of the transmission and running systems leads to operational and economic costs, violation of the technical indicators of mobile power tools laid down by the manufacturer. It also has a negative impact on the environment. At present, only a few domestic and foreign companies have equipped the equipment they produce with digital systems for monitoring the technical condition of power transmissions and running systems, and even then by one or several parameters. These are systems that measure the level of wheel slippage of the tractor, the temperature and pressure in the tires, the angle of inclination of the tractor, as well as the systems that control the optimality of the conversion of engine power to tractive force. The main mass of tractors has no control system during operation and diagnostics of components and assemblies of the transmission and chassis systems is carried out by the tractor operator «by eye», based on his experience and fairness. This often leads to serious violations and equipment operates in modes and loads close to failure. Therefore, it is necessary to introduce into the design of modern technology integrated system for monitoring the state of power transmission and running systems, based on the use of digital technologies. As an experiment, a prototype model of such a control system was developed, including various sensors, both embedded and external, the hardware of the Arduino microcontroller platform, as well as widely available applications for the smartphone, allowing to measure and display on the screen the necessary information about the current state of the units and components. The smartphone is supposed to be mounted in the cab of the tractor. The prototype was tested and can be considered successful. Therefore, in the future it is planned to expand its functionality and add elements.
