Elettronica Frisone

dell' ing. Fulvio Tosi

Design and production of electronic devices: boards, interfaces, sub-systems, microcontrolled devices with relevant software and/or firmware


Fulvio Tosi, the firm owner, began its activity in the naval electronic field in 1970, when he partecipated to the research program "Progetto Esquilino" developed by the "Laboratorio per l'Automazione Navale" ( Naval Automation Laboratory), today "Istituto per l'Automazione Navale" of the C.N.R. (Italian National Research Council).
His main task was to check and improuve the new experimental instrumentation installed on board the ship Esquilino, and to partecipate to the development of the first automatic control of the ship main propulsion from the bridge by means of a digital computer (IBM 1180).  EF0331r1 
Later (1972) he joined CETENA, today a research center of Fincantieri, where he designed and made the first engine room and refrigerated cargo monitoring systems based on a digital computer (IBM S/7), and developed an acquisition system for ship trials data and successive automatic elaboration.
In 1986 he leaved CETENA and set up the Elettronica Frisone, developing collaborations mainly with firms involved both in ship automation or in  naval manouevering simulation (full mission bridge simulators)
Some of the main product developed were, in the simulation field, the full mission bridge simulator with interfaces to generate radar and sonar video signals, simulated naval communication systems, bridge instrumentation. While in the automation field, many different electronic boards and small systems for specific functions (mainly measuring and alarm systems), but the most innovative product, it was 1984, was the GPPC (General Purpouse Programmable Controller, approuved by RINA) to solve most of the automation needs on board ships. At that time there were not yet on the market products with such characteristics that now are a standard. The GPPC (known as PL887 sold by Pizzorno & Lini s.r.l.) was a controller fully programmable and editable in the field, with inputs and outputs both analog  and digital.
Applications were in automation of  electrical plants, boilers, main engines, thrusters and so on.


The main activity is the custom design and production based on the customer needs and specification, but a particular product became a standard:

- Engine order telegraph EF0557


The engine order telegraph, type approuved by RINA (Italian Naval Register), has the particular characteristic to use only three wires to power and connect devices in all stations.
Dimensions are 144x144 mm.
Up to 5 units can be connected together: bridge, port wing, starboard wing, engine control room and engine room.
The bridge unit send the information of the command set from the bridge and the answer from the engine, using the NMEA standard protocol, in order to be connected to a VDR (Voyage Data Recorder).
Each units has a normally closed contact to be connected to an alarm/monitoring system, in order to generate an alarm in case of a fault or when switchnig off the device (OFF button).
