Object of the invention
[0001] The object of the present invention refers to a monitoring and control system of
beverage dispensing installations, which provides a series of advantages and structural
and constituent characteristics, which represent an improvement over the state of
the art.
[0002] Specifically, the object of the invention is centered on a monitoring and control
system applicable to beverage dispensing installations, preferably beer, to bars,
restaurants and catering establishments; said installations having beverage dispensing
equipment with several tanks containing the beverage to be dispensed and piping for
distribution of the beverage from the tank in use to a dispensing tap; a cooling system
of the beverage to be supplied, and pneumatic equipment responsible for pressurizing
the tanks and pushing the beverage into the transport pipes.
Field of application of the invention
[0003] The field of application of the present invention is in the hotel and catering sector
and in particular in the control of beer dispensing installations, or other refrigerated
beverages, from large-capacity tanks located in the establishment itself.
State of the art
[0004] Installations used in hotels and restaurants for the supply of chilled beverages,
such as beer, are well known in the market, said beverages being contained in large
capacity tanks and served by one or more dispensing taps to said tanks.
[0005] These installations reduce the logistics and costs for establishments selling beer
precisely because of the high capacity of the tanks located in those establishments
where beer is to be consumed.
[0006] Obviously, these installations require a series of operations to guarantee the supply
through the dispenser tap, such as changing the connection of the pipes from an empty
tank to a full one when the beverage contained in the tank in use has been consumed.
[0007] The manual control of the beverage dispensing system is bothersome for the staff
of the establishment concerned.
[0008] One solution to these drawbacks is to automate the operation of the installation.
In particular, document
ES 2 579 105 B1 describes automated equipment for beer dispensing installations with several tanks
with outlets connected to refrigerated pipes which transport the beer to at least
one tap; and with a series of pneumatic taps which make the necessary operations possible
with the use of the tank from which the beer is to dispensed.
[0009] The equipment object of said antecedent includes a control unit for each tank in
the installation and a main control unit responsible for controlling the operation
of electrovalves and regulators, connected to pneumatic equipment, which perform the
opening and closing of the beverage conduit and the pressurization of the tanks to
push the beverage contained therein to the supply pipes.
[0010] This equipment allows one to know the temperature and pressure parameters of the
beverage contained in each of the tanks by means of a series of sensors provided for
this purpose in the tanks and connected to the control unit of the corresponding tank.
[0011] This equipment represents an important advance in terms of the handling and control
of the installation which can be carried out automatically instead of manually; however,
it has a number of drawbacks resulting in a low level of acceptance in the market.
[0012] One of the main drawbacks of this equipment is that it is extremely pricey, determined
in large part by the structure of the equipment, which requires control units for
each of the tanks, and additionally a main control unit.
[0013] Another disadvantage of this equipment is that the electronics are closed and limited
to a series of control units, so it does not have the flexibility necessary to adapt
to different installations and obtain data that can be essential to determine the
content of each tank.
[0014] Therefore, the technical problem that arises is the development of a monitoring and
control system for beverage dispensing installations, which is both economical and
accessible for the market, and which allows the sending, to a remote center or terminal,
of certain data relating to the installation and which allows the aforementioned problems
to be resolved.
Description of the invention
[0015] The monitoring and control system of beverage dispensing installations, the object
of this invention, is applicable to those dispensing installations which have: - beverage
dispensing equipment with several tanks containing the beverage to be dispensed and
with pipes for the transport of the beverage from the tanks to at least one dispensing
tap; - a refrigeration system for the beverage to be supplied, and - a pressurization
system for the tanks.
[0016] This monitoring and control system has some construction features that significantly
reduce the manufacturing and implementation costs with respect to the aforementioned
antecedent, making it unnecessary to incorporate a control unit in each tank to determine
the temperature, pressure and level of the beverage inside the corresponding tank.
[0017] Another of the objectives of the present invention is that the system has a modular
configuration, in which the modules communicate wirelessly, minimizing in this way
the installation of the system and making the expansion thereof more flexible.
[0018] These modules have suitable wireless communication means for communicating their
status and values, as well as for receiving orders from a control unit wirelessly.
[0019] All modules are prepared to update their own firmware wirelessly, without intervention
by an operator in the installation.
[0020] According to the invention, the system comprises: a control unit; a control of the
beverage dispensing installation and; a variable and expandable number of auxiliary
modules for telematic control of the beverage refrigeration and tank pressurization
units.
[0021] The control unit is equipped with a user interface, a microprocessor and an electronic
board to control the operation of the system; and radio frequency wireless communication
means to receive different operating parameters of the system from the control module
and the auxiliary telematic control modules, and to send certain data, e.g. the operating
temperature of the refrigeration unit or the pressure supplied to the tanks; or the
sending, to the beverage supplier, of the data relating to the quantity of beverage
remaining in the tanks, which makes it possible to optimize the distribution and prevent
the establishment's tanks from running out of beverage.
[0022] The control module of the beverage dispensing equipment is connected to the control
unit, preferably by cable, and has wireless communication means for receiving data
from the auxiliary telematic control modules of the installation.
[0023] This control module also has an electronic board that controls the opening and closing
of the beverage outlet from each of the tanks to the beverage supply pipes by means
of electrovalves.
[0024] This control module has flow meters that provide the system with information on the
quantity of beverage supplied by each tank and allows one to determine the amount
of beverage remaining in each of the tanks.
[0025] As mentioned above, this system includes auxiliary modules for telematic control,
the number of which can be increased by adapting it to each installation and depending
on the parameters to be monitored therein.
[0026] These auxiliary telematic control modules have an electronic board and specific sensors
that monitor the desired parameters of the installation, for example, of the cooling
and tank pressurization units and they act on them maintaining these parameters within
predetermined values; said auxiliary modules sending the corresponding information
through wireless communication means to the control module that acts as a link between
the control unit and said auxiliary modules.
[0027] Both the control unit and the control module and the auxiliary modules are equipped
with an external power supply and batteries for power supply in case of failure of
the external power supply. These batteries are capable of keeping the measuring system
active autonomously, that is, in the absence of external power for a period of at
least 8 hours, avoiding, moreover, the loss of information.
[0028] In the present invention it is foreseen that the system will additionally comprise
a remote control provided with an internal battery, a communication module, an electronic
board and pushbuttons to stop and change operations of the tank in use by activating
the output electrovalves of said tanks.

the quantity of beverage delivered from the tanks (11, 12) to the respective pipes
(13, 14) and enable the system to determine the quantity of beverage remaining in
each of the tanks.
[0041] The above mentioned control module (5) has a battery (57) to supply it with power
for at least 8 hours, in case of external power failure.
[0042] The auxiliary module (6) has: wireless communication means (61), an electronic board
(62) and a battery (63) to supply it with power in case of external supply failure.
[0043] These sensors can be of different types depending on the parameters to be monitored;
they are represented in this example by: a temperature probe (64) responsible for
detecting the temperature of the cooling liquid passing through the recirculation
conduit (22) of the cooling system; a clamp meter (65) to detect the consumption of
the refrigeration unit (21) and a pressure transducer (66) which detects the pressure
applied by the pressurization unit (3) to the tanks (11, 12)
[0044] As shown schematically in the mentioned figure 2 this auxiliary module (6) also has
means of control (67) to act on the monitored equipment, e.g. cooling system (2) and
pressurization system (3) in order to keep the values captured by the sensors (65)
within predetermined parameters.
[0045] These means of control (67) may be e.g., relays or any other means.
[0046] The remote control (7) has an internal battery (71), wireless communication means
(72) and an electronic board (73) with pushbuttons (74) to stop and change operations
of the tank (11, 12) in use by acting on the electrovalves (53, 54) associated with
