[0001] The present invention relates to an electronic system for controlling gates or doors,
in particular having two or more wings, with automatic opening, for vehicle and/or
pedestrian passage, that allows automatic opening gates to be installed in a simple,
reliable, safe and inexpensive way, the system being easily integratable with the
structure wherein it is installed.
[0002] In the following, the system according to the invention will be described with reference
to its application to automatic opening gates, but it should be understood that it
may be applied to other automatic opening apparatuses for delimiting rooms and spaces,
such as doors, still remaining within the scope of the present invention.
[0003] It is known that systems for opening two-wing gates or doors requires a synchronisation
among two or more automatic sub-systems, which operate in a specific sequence, each
one of which controls a corresponding wing. Such synchronisation entails the installation
of one or more connections and wirings among the same.
[0004] By way of example, Figure 1 shows a gate having two wings, respectively right 1 and
left 2 (looking at the gate from outside the zone 3 delimited by the same), pivoted
on a respective post, 11 and 12. Each one of the two wings 1 and 2 is moved by a respective
mechanical arm, 4 and 5, coupled to the corresponding wing, 1 or 2, and operated by
a respective electric motor, 6 and 7, so as to open or close the corresponding wing,
1 or 2. The system further comprises an infrared or IR transmitter 8 and an IR receiver
9, facing each other so as to form an infrared ray barrier operating as anti-collision
detector for persons and vehicles which possibly pass during gate movement. Finally,
the system of Figure 1 still comprises a light signalling device, in particular a
flasher 10, that flashes during the movement of the two wings 1 and 2.
[0005] Figure 2 shows electrical connections among the various components of the system
of Figure 1 that is necessary to make in order to install the same system. In particular,
the system comprises an electronic unit 13, located in correspondence with one of
the two posts 11 and 12 of Figure 1, that controls the motor 6 and the motor 7 in
a synchronised way, through corresponding wirings 14 and 15, that interprets detections
made by IR transmitter 8 and IR receiver 9, which are received through corresponding
wirings 16 and 17, and that controls the flasher 10, through a corresponding wiring
18.
[0006] Considering that other electronic systems and/or other configurations of electronic
systems (for instance, multiple master/slave ones) for controlling gate or door opening
require similar connections among several components, it is evident that present control
electronic systems suffer from significant drawbacks due to the complexity of installation
of wirings among the electronic unit and the motors operating the wing mechanical
arms, and among the electronic unit and several mandatory safety devices, usually
imposed by law provisions, such as the flasher and the IR barrier.
[0007] First of all, in most cases, automatic opening systems for gates or doors must be
installed within structures which are not prearranged during the design phase to be
provided with such.
[0008] Moreover, since, due to practical and/or aesthetic reasons, in nearly all real cases
it is not possible to make an aerial connection, it is necessary to make an underground
cable duct (in particular electrical pipes according to EN provisions on AC high voltage
systems) between the post on which the box 13 is installed and the other post. Considering
that a driveway is usually located between the two wings, this entails significant
inconveniences for both the use of the driveway and the installation of the control
system.
[0009] Still, often such control electronic systems cannot be installed due to the fact
that the structures which are to house them do not allow to make such connections.
For instance, it is this the case of structures of particular artistic or monumental
relevance, such as driveways in ancient buildings.
[0010] Furthermore, the connection cables between the unit 13 and the various system components
are often specific for each component, thus increasing complexity and costs of the
installation of the system. For instance, the IR transmitter 8 and the IR receiver
9 are connected by a specific multicore cable.
[0011] Still, the installation of the electronic system requires the work of specialised
technical personnel, capable, for instance, to operate with live terminals and to
carry out adjustment by means of trimmers located on an electronic board, usually
internal to an outdoor sealed housing. This increases complexity and cost of installation
and maintenance of the system.
[0012] Finally, complexity of wiring installation represents a not negligible cost, often
higher than that of the same system.
[0013] It is therefore an object of the present invention to provide electronic systems
for controlling gates or doors, in particular having two or more wings, with automatic
opening, which are reliable and safe and which may be installed in a simple, fast
and inexpensive way, the system being easily integratable with the structure wherein
it is installed.
[0014] It is specific subject matter of this invention an electronic system for controlling
gate or door opening, capable to control means for moving two or more wings, characterised
in that it comprises at least one master electronic unit, and at least one slave electronic
unit, capable to control a respective portion of said movement means, said at least
one master electronic unit and said at least one slave electronic unit communicating
with each other through at least one two-way communication channel established between
at least one first transceiver device, connected to said at least one master electronic
unit, and at least one second transceiver device, connected to said at least one slave
electronic unit, said at least one two-way communication channel being selected from
the group comprising a wireless optical channel, a wireless radiofrequency channel,
a wireless electromagnetic channel, a wireless ultrasound channel, and a power line
channel.
[0015] Preferably according to the invention, at least one master electronic unit is capable
to control a synchronisation of at least one respective portion of said means for
moving said two or more wings.
[0016] Always according to the invention, at least one master electronic unit may be capable
to control a respective portion of said movement means.
[0017] Still according to the invention, the system may comprise receiver means capable
to receive at least one signal generated by a remote control and/or a transponder,
said at least one master electronic unit capable to control said synchronisation of
at least one respective portion of said means for moving said two or more wings setting,
when said receiver means receives at least one signal generated by a remote control
and/or a transponder, one or more mode of operating said movement means.
[0018] Furthermore according to the invention, said two or more wings may comprise at least
one sliding wing and/or at least one revolving wing, and/or at least one sliding wing
and/or at least one tilting wing.
[0019] Further embodiments of the system according to the invention are described in dependent
claims 2-15.
[0020] The present invention will be now described, by way of illustration and not by way
of limitation, according to its preferred embodiments, by particularly referring to
the Figures of the enclosed drawings, in which:
Figure 1 shows a schematic top view of a gate provided with a control electronic system
according to the prior art;
Figure 2 shows a schematic block diagram of the components of the system of Figure
1;
Figure 3 shows a schematic top view of a gate provided with a preferred embodiment
of the control electronic system according to the invention; and
Figure 4 shows a schematic block diagram of the components of the system of Figure
3.
[0021] In the following of the description same reference numbers will be used for indicating
alike elements in the Figures.
[0022] With reference to Figures 3 and 4, it may be observed that the preferred embodiment
of the system according to the invention is still applied to a gate having two wings,
respectively a right one 1 and a left one 2 (looking at the gate from the outside
of the zone 3 delimited by the gate), pivoted on a respective post, 11 and 12, each
one of which is moved by a respective mechanical arm, 4 and 5, operated by a respective
electric motor, 6 and 7.
[0023] The system of Figures 3 and 4, also provided with a flasher 10, further comprises
a first IR transceiver 28 and a second IR transceiver 29, facing each other so as
to form an infrared ray barrier for anti-collision detections.
[0024] As shown in Figure 4, the system according to the invention comprises a first master
electronic unit 20, that controls motor 7 operating the mechanical arm 5 coupled to
the left wing 2, and a second slave electronic unit 21, that controls motor 6 operating
the mechanical arm 4 coupled to the right wing 1 and to the flasher 10.
[0025] The first and the second IR transceivers 28 and 29, respectively connected to the
master unit 20 and slave unit 21, are the terminals of the infrared wireless two-way
communication channel capable to exchange control digital signals between the master
unit 20 and the slave unit 21.
[0026] In particular, the master unit 20 preferably comprises at least one microprocessor
(possibly in multiprocessor configuration) that also controls the operation of the
slave unit 21 (still preferably comprising at least one microprocessor, possibly in
multiprocessor configuration), by sending suitable encoded commands and receiving
information signals (for instance related to the state of slave unit 20, motor 6,
or flasher 10), through the infrared communication channel established by the first
and second IR transceivers 28 and 29
, specifically for controlling synchronisation of motors 6 and 7 and, hence, movements
of the wings 1 and 2.
[0027] In this way, it is no more necessary to make wirings connecting the several components
of the system placed in correspondence with the two gate posts 11 and 12 (as instead
the case is, for instance, for the connection between unit 13 and motor 6 of the prior
art system of Figures 1 and 2). In fact, it is sufficient to make connections 15'
and 16' (local to the left post 12) between master unit 20 and, respectively, motor
7 and first IR transceiver 28, and similar connections 14', 17', and 18' (local to
the right post 11) between slave unit 21 and, respectively, motor 6, second IR transceiver
29, and flasher 10. In particular, master unit 20 and slave unit 21 are power supplied
by respective electrical energy sources, such as respective outlets present, for instance
sue to lighting reasons, in proximity of both gate posts 11 and 12. Alternatively
(or additionally), master and slave units 20 and 21 may be power supplied at least
partially through solar panels and/or batteries; in particular, the first and/or the
second IR transceivers 28 and 29 may be power supplied through solar panels and/or
batteries.
[0028] Other embodiments of the system according to the invention may comprise a different
arrangement and/or composition of the various system components. For instance, the
flasher 10 of Figures 3 and 4 (or a second visual signalling device) could be mounted
on the left post 12 and directly controlled by the master unit 20; otherwise, other
safety devices, for instance acoustic signalling devices, could be mounted on either
one or both gate posts 11 and 12.
[0029] Other embodiments of the system according to the invention may comprise, alternatively
or additionally to the infrared one established by first and second IR transceivers
28 and 29 of Figures 3 and 4, different wireless two-way communication channels. For
instance, a wireless, preferably infrared or laser, optical channel could comprise
a transceiver device integrated into the flasher 10, capable to communicate with the
first IR transceiver 28 or a different device, facing the flasher 10 and mounted on
the left post 12. Other embodiments may comprise radio wave transceiver devices, such
as for instance WI-FI, GSM/GPRS, or Bluetooth, rather than infrared, ones. Furthermore,
a two-way communication channel between master unit 20 and slave unit 21 may be established
through waves conveyed over the preferably pre-existing mains (power line channel).
Still, the wireless communication channel between master unit 20 and slave unit 21
may be established by means of ultrasound capsules. Furthermore, the wireless communication
channel may be established through magnetic or variable reluctance electromagnetic
devices.
[0030] Other embodiments of the system according to the invention may control automatic
closing apparatuses including a plurality of portions which may be moved independently
of each other, and which need a synchronisation control. For instance, gates comprising
a plurality of wings, or complex apparatuses comprising a plurality of gates. In this
case, the system according to the invention may comprise more than one master unit
and/or more than one slave unit, each one of which operates similarly to the units
20 and 21 of the system of Figures 3 and 4, communicating with one or more of the
other units (preferably a main master unit controls the synchronisation of the whole
system).
[0031] Moreover, the system according to the invention may comprise various methods for
activating the automatic opening, for instance two different motor drives both using
a respective receiver of a signal generated by a remote control or a transponder.
[0032] Preferably, the system according to the invention provides that all the electrical
connections and adjustments of the system, necessary for installation, test, calibration,
and maintenance, are capable to be made directly by the end user, even without any
specific skill, who, not having to directly operate on the internal components, is
able to autonomously operate on the system.
[0033] The advantages offered by the system according to the invention are evident.
[0034] First of all, thanks to the presence of master unit 20 and slave unit 21, indirectly
connected to each other, preferably through a wireless channel, it is no more necessary
to underground cables (related to power supply, signal communication, and other requirements)
between the two gate posts. This entails evident advantages, in particular in case
of a driveway, in terms of costs, short installation time, and lack of impact on the
pre-existing structure.
[0035] The present invention has been described, by way of illustration and not by way of
limitation, according to a preferred embodiment thereof, but it should be understood
that those skilled in the art can make variations and/or changes, without so departing
from the related scope of protection, as defined by the enclosed claims.
