`PROGRAMMABLE ELECTRONIC CONTROL
`UNIT FOR AUTOMATIC WATERING
`SYSTEMS
`
`BACKGROUND OF THE INVENTION
`
`Field of the Invention
`
`The present invention refers to a programmable electronic
`control unit for automatic watering systems, preferably for
`watering systems with plural lines.
`For the maintenance of lawns, gardens, kitchen gardens
`and other cultivated spaces, the employment of automatic
`watering systems controlled by a programmable electronic
`control unit is increasingly widespread.
`The control unit can be either of a simple type capable to
`control one watering system, for instance with one single
`line, on the bases of watering programs pre-set by the
`producer, that the user can only select according to his/her
`own needs, or of a more complex type, both in terms of
`performance and number oflines, and to offer the user the
`possibility to program the control unit on his/her own.
`It is quite clear that in this latter case the easiness of
`programming becomesa primary need,suchasto decisively
`influence the choice in the purchase of the control unit.
`
`SUMMARY OF THE INVENTION
`
`Object of the present invention has therefore been to
`realise a controlling electronic control unit for watering
`systems that would be easily and quickly programmed by
`the user.
`
`According to the invention, such object has been attained
`by meansof an electronic control unit comprising an elec-
`tronic circuit with a programmable processing unit, operat-
`ing buttons to execute and to vary the programming of said
`processing unit and a display for the visualisation of the
`programming stages. The programmable processing unit is
`organized to individuate a programming menu that is sub-
`divided into a plurality of parts selectionable at will. Each
`part comprising at least one chapter. The said chapter being
`formed of at
`least one page of setting for at
`least one
`respective programming parameter, and in that each part of
`the menu is directly and independently selectionable by
`pressing on at least one respective operating button.
`The subdivision of the programming menu into several
`parts, each one directly and independently selectionable by
`means of at least one respective operating button, and of
`each part into one or more chapters makes the operation of
`the control unit programming extremely simple, allowing in
`addition to accede only to those programming functionsthat
`one wishesto set or to modify.
`Further scope of applicability of the present invention will
`become apparent from the detailed description given here-
`inafter. However, it should be understood that the detailed
`description and specific examples, while indicating pre-
`ferred embodiments of the invention, are given by way of
`illustration only, since various changes and modifications
`within the spirit and scope of the invention will become
`apparent to those skilled.
`
`BRIEF DESCRIPTION OF THE DRAWINGS
`
`The characteristics and the advantages of the present
`invention will be rendered more evident in the following
`detailed description of a possible embodiment
`thereof,
`which is illustrated as a non-limiting example in the
`enclosed drawings, in which:

`
`DESCRIPTION OF THE INVENTION
`
`The control unit shown in FIG. 1 has a box casing 51 of
`an approximately parallelepiped shape,
`inside which an
`electronic circuitry is housed, that comprises, amongothers,
`an electronic circuit with a programmable processing unit,
`various input and output wires associated with a terminal
`board (not shown) and with a buffer battery. According to a
`variation, the box casing 51 can also serve as a housing for
`an electric transformer capable to reduce the input tension of
`the power of mains.
`On one upper face 53 of the box casing 51 operating
`buttons 54-61 are present. The buttons 54+56 are located
`substantially below a display 63, while the buttons 57+61
`are lined up on oneside of the display 63. Hereinafter, the
`buttons 54+61 will be designated by using the nomenclature
`listed below (nomenclature that preferably corresponds to
`graphic indications that are inscribed on the face 53 beside
`the same buttons):
`button 54: “-”
`button 55: “ENTER”
`button 56: “+”
`button 57: “PROGRAM A”
`button 58: “PROGRAM B”
`button 59: “PROGRAM C”
`button 60: “SETTING”
`button 61: “MANUAL”
`The display 63 is destined to the visualisation of a series
`of symbols, that are indicative of the programming stage
`under course, as well as of the current time and of other set
`functions that will be illustrated, together with the meaning
`of the various symbols illustrated as a whole in FIG. 3,
`further on in this description.
`A transparentlid 50 is hinge coupled to the box casing 31
`in order to be overlapped to the upper face 53 of the box
`casing itself as a protection for the operating buttons and of
`the display, and at the same time to be opened as shown in
`FIG. 1 at the time of programming.
`FIG. 2 showsa possible scheme of functional blocks of
`the electronic circuit of the control unit,
`that comprises
`essentially a programmable processing unit with micropro-
`cessor 62 controlled by operating buttons 54+61 and con-
`trolling in turn the display 63. In addition, the processing
`unit 62 is controlled by a pair of predisposition selectors 100
`(not shown in FIG. 1) that provide for the selection of the
`numberof outputs to control (for example 6 or 8 or 10 or 12)
`and for the selection of the input frequency (for example 50
`Hz or 60 Hz), and it receives a low tension alternated power
`supply (for example, 24 WAC)
`from a transformer 68
`through which a synchronism circuit 101 is piloted. The
`transformer 68, or as an alternative a buffer battery 102,
`provides also for the supply of the electronic circuitry 103
`necessary for the generation of the tensions required for the
