<p>Method and apparatus which are the subjects of protection, represent the functional solution and construction support of the smaller electric devices, e.g. the various machines and tools, e.g. drills, drilling hammers, hand grinding machine etc., also appliances like electric mixers, liquidizers, robots, vacuum-cleaners, etc., and apparatus of these enabling the data recording electric devices operation time optionally their processing. The apparatus itself is based on the fact that the primary conclusion of the system is following: electrical device (6) is equipped both with electrical measuring device (9) and electrical communication system (12). Both systems are located in the space restricted by the safety cover (7) of the electric device. It consequently represents a connection comprising of the electric device (6) equipped with electronic measurement chip (8) as the element of the electrical measuring system (9) connected to the outlet brace (10) of the switch (4) and as the element of the electrical communication system (12) connected to the inlet terminal (13) of the switch (4). Joining electrical conductor (1) of the electrical device (6) connected either to mains (3) or communicatively attached to the external data reading device (14), respectively with attached computer (17), or to the external computer (18) equipped with communication hardware, while at least external data reading device (14) and the external computer (18) are attached to the line voltage conduction.</p> |
