It is the aim of the present invention to guarantee the automatization of the greatest part of said plants , with the possibility of amplification for the solution of the most different problems, in the mentioned utilization field. The aim set forth is reached by means of a system according to the present invention, arranged for an easy insertion into the line to be intercepted, and consisting of: • a central control unit - trasmission lines and alarm; • perifherical station; • devices/sensors connected to the receiving station, receivers, urban waterworks with internal station, depurators, reuse of industrial/irrigation waters with return of the resource to nature; • plurality of plants on the territory comprising: • a computerized system for the check of the fluids; • a capacity meter; • an elettronic pressure transducter; • a motorized valve; • a disassembling, folding joint; • a flange, connection piping; • a chimical-phisical analysis mesure cell . The connection between said system and the used devices are performed by means of insertion and watertight/mechanic block connectors, keeping in mind that said power connectors, they can not be inserted or separated under tension. The absolute flexibility of the system according to the present invention implies remarkable advantages, as the devices used, like the motorized valves and the capacity meters, may be of different kinds according to the installation field of said system: in the waterworks, in industry, in agricolture and in the thermic field. The further advantages of the system according to the present invention are the following: • easy mechanic insertion in the line; • usefulness in different application fields ; • use of also non-technical staff; • easy remote-managing. The present invention will be described more in detail hereinbelow realting to the enclosed figures in which some embodiments are shown. Figures 1 and 2 show the blok schemes, respectively of the water cycle and of the remote-controlled plant, with peripheric station FCS. Figure 3 shows a plant with an automatized system for the fluid check. The remote-control system is working all around the clock, providing the operator in the control station with the functioning situation of the programmable stations , and underlines possible alarms produced by the devices connected to the stations. The system according to the present invention is used for the supervsion and the centralized check for the safety systems and technologic plants and is prepared to manage up to N remote programmable stations . Furthermore, the control station can manage a serial, asynchronous line for performing the connection with a "host computer" . By means of the transmission record, integrated in the system and transparent to the used, the data collected by the remote stations are acquired by the central system and saved in the system base. For what concerns the managing of the data bank, the latter contains the information received from the periphery and makes them available for further treatments and/or visualization. Invention allows to integrate one self with others technologies, like S.I.T. in 6IS, to keep a highest technologic level of new conception. Utilizing all information trasmissed by peripheric system to data bank and after inputting them in appropriate mathematic model, is possible to directly book-keepper consumption, checking wastes and indirectly search of water loss . According to the present invention, the monitoring and cheking occurs in real time, according to the scanning frequencies allowed by the communication net, as the central system allows to monitor the state of the peripherical process and to send the remote stations activation drives. The operatore superintends the process through the operator station; on the screen appear, in a dynamic graphic shape and in colours : • front desks of peripheric instruments with description and numeral values for the shown variables; • synoptics, comprising the location of the sensor with graphic colour underlining of the state, dynamically managed with variations in colour, shape, position or combinations; • alarm signals; • trend of requested variables . The setting out of the drives by the operaor takes place by means of a keyboard or a "mouse" . The print in hard copy of a video is provided for: • The alarms are run in real time with gaphic signalling on the video and acoustic signalling; a plurality of priority levels are run, as well as the identification of every alarm. The print of the alarms on request and/or their recording onto a disk in files of ASCII format, are provided. • Trends in real time or historic trends are available for the user, of analogic and digital variables ; • the central system transfers the data recorded on a hard disk onto a floppy disk, thus allowing further uses on different computers, by means of particular procedures written by the user as well as by standard package; • insertion check of the plants and/or areas with timers: the central system can bring out if the alarm plants have been inserted in the predetermined time periods; at the deadlines of the pretedermined time periods, the system sends a signalling of lack of plant insertion to the operator. Relating now to the figures, the plant according to the present invention comprises: • a central control unit CED - transmission lines LT and alarm AL; • peripherical stations FCS; • devices/sensors connected to the receiving stations CP,receivers SE, urban waterworks RIC with internal stations FCS, depurators DP, reuse of industrial/irrigation waters RII with return RNN of the resource to nature; • a plurality of plants on the territory comprising: • a drive panel 1 ; • a capacity meter 2; • an electronic pressure transducer 3; • a motorized valve ; • a disassembling, folding joint 5; • a flange connection piping right calcolated 6; • a chemical-phisical analysis cell 7. In a possible realization, the control system 1 is provided with four analogical inlets plus nine digital inlets which cover, at the bottom of the scale, a great part of the transducers used in a plant, as pressure measurer, flow measurer and generally level meters, with the relative alarm checkes at the protection limits, and furthermore it is provided with two relay outlets for the realization of alarm devices with remote control , of the kind of pumps, sirens or motorizations of any kind, or signallings of demages or alarm. The system according to the present invention also comprises, for the remote- managing, a modem with a TRSII or MODBUS transmission record. The system according to the present invention is fed, in on line, by a continuity group that balances the lack of net for a time period T = Ih, or by differentiated feedin, like e.g. 12 Vcc. The peripheric stations are remote-managed by means of a device arranged for performing the function of supervision and managing of a historic file of reception of alarm states from the stations connected by means of an optional audio card; the applied software, realized in the windows area, allows the operator to interact as a central with a peripherical , visualizing the state of the examined water filter, together with all parameters set out in the initialization of the plant, with the possibility of modifying the state of the resources . The communications may take place by means of: • a dedicated net, • a commutaded telephone line, • radio transmissions, • a cellular radio, • a private line, • a satellite radio. Once all the specific informations have been inserted, the software runs the whole waterwork, allowing the operator to have - in on line or in time - a detailed situation of the shape of the single element set out, with the possibility of interacting and driving determined managing functions . In the initialization of the system, the data relating to the composition of the single peripheric must be inserted, making use, e.g. , of a telephone line, of the number of one's own line, of five calling numbers used by the peripheric for transmitting in automatic the alarm state; said data consist of minimum and maximum parameters of the analogic measures, with the realtive upper and lower check limits of said measures, and furthermore - for a global view - the description of the transducers used in the peripheric will be inserted. For the recording of the available digital signals, present in the standard form, the description, the alarm state and the recording time of alarm must be inserted into the system program in the central station. These latter information are also for the signal lines of the actuaries.
