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).
(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
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
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.
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, 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.
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).
