Control system for portable dry ice cleaning device

In the paper will be described a control system of a dry ice cleaning system. One such cleaner can be used in various branches of industry such as: electrical, metal, wood, automotive, food, pharmaceutical, plastics, paper and cosmetics industries. It can also be used in printing, steelworks and for removing graphite from the walls by removing impurities and not damaging the substrate material. The dry ice cleaner is characterized by the appropriate speed, flow and vibrations that need to be generated. The cleaner should be robust and have a wide range of operating temperatures. There is a very necessary protection from static electricity, which is easily generated by constant vibration and friction, which can very badly affect, and even lead to the failure of the entire control system. The software of this control system is protected from external influence by WDT, Watch Dog Timer. Also, the software is written so that it can recognize improper handling by a cleaner. In case of improper handling, the software will protect the user.
