Návrh informačního systému traktoru s interaktivním ovládáním prostřednictvím HMI
Jukl, Michal
The dissertation thesis "Design of the Information System of Tractor with Interactive Control by HMI" focuses on the theory of ergonomics of the agricultural tractor cab in the context of the coexistence of standard tactile controls and innovative solutions with touch screen support. The thesis illustratively presents on model examples how an extensive set of information from different disciplines is necessary to meet the goal of synergy of anthropometric or biomechanical properties of the operator and working environment and conditions. This chapter introduces the next section, which details the integration of HMI in the tractor cab. Again, type solutions are demonstrated and there is created a knowledge base on the individual conceptual approaches of the manufacturers. The synthesis of information from the theoretical part of the thesis is projected into its experimental part, whose nature is mainly developmental and purpose-built within the project for the producers of Zetor Tractors, a.s. At first, there are defined solution attributes from various points of view, from which the design and implementation of hardware and software parts is coming out. The physical design of the terminal was carried out in a prototype solution by printing from a thermoplastic polymer. The chapter about terminal software also describes a solution that considers the chosen concept of the information system that is a part of mentioned project. Terminal will run Linux operating system and will work as a web services client. This chapter contains source code fragments to illustrate the selected concept. Due to the scope of the project and the focus of the work, certain parts of the technical solution are only outlined, but the description clearly shows the close connection between the development of the terminal and the central tractor system. It follows from the foregoing that simply verifying the functionality of the terminal is not sufficient for the experiment itself, therefore the whole prototype solution was tested for a specific task in the field of the hydraulic system of the tractor. In contrast to a conventional hydraulic regulator solution, attention was paid to the fuzzy regulator in this study, and the results of the experiment are listed in the relevant chapter. The conclusion of the thesis then focuses on the development of the system and its capabilities in the concept of Agriculture 4.0.
