− technical solutions integrating general – purpose telecommunication and information
systems.
In principle telematics determines new telecommunication systems connected with the
information technology, which in the mining industry relates to teleinformation systems integrating telecommunication with information technology used in these systems (Wojaczek
2017). The last one of the fields – a distribution of products is oriented onto a final recipient,
but a distribution itself is an element of logistic activities in an enterprise (Witkowski 1995).
Due to the continuous striving to increase the safety of mining crews (Latos & Stankiewicz
2015) and to improve the efficiency of mining, transport and coal processing, many R&D
units aim at the research projects on implementation of state-of-the-art control systems as
well as a wireless network of sensors which can cooperate with the distributed control systems (Tanenbaum & Stehen 2006, Jonak et al. 2010). However, the design of self-organizing, distributed wireless sensors networks and control systems requires a development of
an alternative method for power supply of its components through harvesting energy available in its vicinity, e.g., the energy of mechanical vibrations, thermal energy (Woszczyński &
Świder 2014, Wischke et al. 2011, Stankiewicz & Woszczyński 2010, Mitcheson et al. 2008,
Radkowski et al. 2012), and the energy of rotational movement or electromagnetic radiation.
Self-powered sensors are more commonly used in ventilation or air-conditioning systems
and in monitoring the migration of animals and also in the systems monitoring technical
parameters.
Artificial intelligence is more and more commonly used for control and communication in
the mining industry as well as for monitoring and diagnostics of subassemblies and component wear (Prostański & Jonak 2003, Bartoszek et al. 2013). According to KOMAG’s experience, three hardware and software components of the discussed solutions are most important
as regards operational reliability: self-powering sensors, distributed control systems, and selforganizing communication network gathering these components to the system.
2 STATE-OF-THE-ART MECHATRONIC SYSTEMS FOR MINING
2.1 Self-powered sensors
Self-powered sensors are equipped with generators, converting the energy in its vicinity into
electric energy. Depending on the generator design, the self-powered sensors can be supplied
by energy of light, gas flow, mechanical vibrations, or electromagnetic radiation. Electromagnetic or piezoelectric generators are most often used for a conversion of mechanical vibration
energy (Gilbert & Balouchi 2008).
