Opis:: The article presents the results of tests and analyses of control functions performed by a powered roof support which is the basic part of a powered longwall system. The research was based on an innovative registration and measurement system dedicated to this specific range of tests. The basic element of this system is a virtual driver. It is equipped with input and output systems to connect standard physical voltage signals. The tests were carried out on a prototype powered roof support type ZPR-15/35-POz. The presented research methodology and obtained results are an element of new research methods developed for powered support based on virtual controllers. The applied solution generates less costs than the devices currently used, while its functionality is significantly greater. The system developed by the Authors supports innovative and, to a certain extent, intelligent IT solutions for testing control elements. This developed system is suitable to be applied in a wide range of research such as diagnosis of mining machinery control elements and other industries in the near future.

Opis:: Mining machines suitable for hard coal mining, due to the specifics of this industry must be characterized by very high technical parameters. In particular, it concerns their durability, reliability and availability. Currently used machines approved for operation in underground conditions meet such requirements. Nevertheless, during their operation it is reasonable to conduct supervision and control of work parameters. This applies to both machine manufacturers and users, which is especially important in the event of a failure. Mine employees should be able control of the entire operation process. This control can be effective thanks to a visualization system developed to monitor the working parameters of mining systems. The paper discusses the innovative system and presents the results of efficiency tests. They concerned the visualization of the operation of a powered roof support. The obtained results indicate that the assumed goal of the system has been achieved. The system is built on elements of industrial automation, which guarantees the reliability of the indicated values. Its graphic layout and selection of the presented parameters are also approved. It should also be emphasized that the system can work with currently operating systems and is easy to expand. According to the Authors, the system should find a wide application in practice.

Tytuł:: Tests of an Innovative Controller Designed to Control the Powered Roof Support

Opis:: The article presents the methodology and results of tests of a prototype controller designed for the electrohydraulic control system of a powered roof support. This controller is the basic part of the developed, innovative control system. The tests were carried out on a custom-designed testing station, equipped with one section of a roof support. The aim of the research was to check the functionality and speed of the controller's response while working with the actual support section. The tested controller and the control system has a modular structure, which greatly facilitates its operation and use. Measurements of control functions were carried out on the controller connected to the electrohydraulic control block. The research mainly focused on determining the period starting from the moment of providing the signal to the moment of switching on the basic functions performed by the support section. The obtained results confirm the assumptions made. The controller's operation is very stable, and its response times are very short. It can therefore be assumed that the tested controller is correctly designed and constructed. This creates great possibilities for its practical application in the built-in system for controlling the roof support. This may be particularly important in the case of high-efficiency longwall complexes, for which wireless control of the support is planned to be used. The presented research methodology and obtained results should therefore be an important source of information in the field of testing controllers for powered roof supports.
