Definitions

  • the invention refers to a system for radio-communication allowing to send news or to perform radio-orders in a selective way and in actual time.
  • the system can be carried out with an operating centre acting as a data bank and to connect also with outer centres with a view to transmitting radio electronic data which can be received by means of devices foreseen for this purpose at the users' disposal.
  • the invention system allows to supply the data at the user's home at moderate costs, thus permitting unlimited information without com­pelling the user to take part to the research.
  • the system enables the user to receive journal news of general or par­ticular character, such as: bulletins, chronicles or else, thus ob­viating the necessity of printing the publications and of sending them already manufactured, as a premise of reading, therefore, of learning.
  • the system also allows to perform the control of machine­ry and equipments from a distance, thus obviating the necessity of carrying out these operations by hand on the spot.
  • the system enables to communicate a message by writing, independently from the vicinity of the reception system of the called subject.
  • the system foresees the use of a redaction compu­ter 5 to collect data through either operator- service unit and/or in connection with outer sources of types 1, 2 and 3 connected through jonction 4.
  • the data will be put into the modular-adapter 7 by means of line 6, to then enter into the modulator-transmitt­er 8 and to be amplified by the amplifier 9 and irradiated by the antenna system 10.
  • the antenna system 11 of the user will pick up the high frequency signals which, through receiver 12, will be tran­sformed into low frequency and given up to a modulator-adapter 13 which makes the data suited for a microprocessor 14 acting as a data access key. Also in only one emission, this allows the differentia­tion in the reception of the message-data.
  • This equipment 15 may consist either of a printing unit of of a magnetic memorization device for computers, if either an in­formation text or an image is transmitted.
  • the equipment 15 can also consist of a transducer for the control of distant electrical machin­es or equipments. To enable the user to ask for particular news and/­or services, a requiring compartment is foreseen (either 19 or 20 or 21) which integrates the means (either 16 or 17 or 18).
  • Functions a), b) and c) will be carried out autom­atically by means of computers 19 or 20 or 21, compatible with re­daction computer 5.
  • the user will only have the task of choosing the news through digitation of the relevant news-codes.
  • the redaction computer 5 will have the following data at its disposal: data and hour of the call, number of the unit recognizing the asking user, reason of the call, specific orders. All these data, through the com­puter 5 elaboration, enable the subsequent sending of the particular service asked for, as well as the performing of periodical statements of account for computing the performances asked for by each user.
  • fig. 1 is a block scheme of a transmitting device for three users who own receiving equipments as per figures 2, 3 and 4.
  • Fig. 5 is the block scheming of figures 1, 2, 3 and 4 with addition of the devi­ces required for the interaction from the receiving system with the transmitting one as per fig. 1.
