Description

Movable Barrier Actuating System

Field of the Invention

The present invention relates to a movable barrier actuating system for use in buildings that require natural ventilation. Particularly, the present invention relates to a reactive acoustic window actuating system wherein the reactive acoustic window actuating system actuates a window in response to an unfavourable external noise.

Background of the Invention

Using windows for natural ventilation is one of the oldest and most sustainable strategies for providing ventilation (and sometimes cooling) to buildings. Modern urban and rural environments often have significant background noise that enters internal spaces through open windows. This can cause disruption to occupants of buildings, preventing sound sleeping in residential properties or affecting educational outcomes in schools. This background noise can often be intermittent with amplitude peaks causing the most disruption. For example, a residential area situated under or near a flight path to a major airport will be subject to the disruptive noise of an aircraft. Such instances can be unpredictable and so are difficult to account for using current technology.

Currently methods of control for naturally ventilated internal spaces do exist. One such method involves measuring the temperature of the internal space and opening the window in response to a high internal temperature or closing the window in response to a low internal temperature. Further methods exist that provide control in response to fluctuations in internal CO2 levels and internal moisture levels.

One issue of these existing methods is that they do not provide an improved internal acoustic environment in areas where there are loud intermittent noise sources.

It is therefore desirable to provide a means of providing control of naturally ventilated internal space in response to intermittent external noises that may be unfavourable to the internal environment.

Summary of the Invention

In accordance with a first aspect of the present invention, there is provided a movable barrier actuating system arranged to modify an opening partially bounded by a barrier, said movable barrier actuating system comprising: a first microphone configured to: detect a first noise source originating from a first environment, the first noise source comprising an acoustic signature and acoustic characteristics; a movable barrier actuator configured to actuate a corresponding movable barrier; a transmitter in communication with the first microphone arranged to transmit a first real-time acoustic spectrum representative of the first noise source; and a controller configured to: receive the real-time acoustic spectrum from the transmitter, the real-time acoustic spectrum comprising the acoustic signatures and the acoustic characteristics; and to transmit an actuation signal to the movable barrier actuator in response to the first real-time acoustic spectrum exceeding a predetermined threshold requirement, so as to modify said opening with actuation of the barrier.

It shall be appreciated by the skilled addressee that there may be more than one first noise sources.

The term "movable barrier" in the context of the present invention will be understood by the skilled addressee to describe a barrier separating the first environment and the second environment, the barrier being movable so as to either bound the opening to a greater or lesser degree such that the opening is either smaller or larger in area with respect to an initial bound position.

The "first environment' and "second environment" in the context of the present invention will be understood by the skilled addressee to be two environments separated by the movable barrier.

The term "acoustic signatures" in the context of the present invention will be understood by the skilled addressee to be a combination of acoustic emissions associated with unique sound emitters.

The term "acoustic characteristics" in the context of the present invention will be understood by the skilled addressee to be any property of an acoustic wave associated with the first noise source.

In preferred embodiments, the predetermined threshold requirement is a predetermined amplitude threshold requirement. In this way, if the real-time acoustic spectrum comprises an amplitude that exceeds the predetermined amplitude threshold requirement (i.e. is too loud); the controller may transmit the actuation signal. Additional embodiments exist wherein the predetermined threshold requirement is a predetermined frequency or any other acoustic property threshold requirement. Further embodiments exist wherein the predetermined threshold requirement comprises a predetermined amplitude threshold requirement, predetermined frequency threshold requirement and any other predetermined acoustic property threshold requirement.

Preferably, the controller is further configured to detect an unfavourable acoustic signature and transmit the actuation signal in response to the detection of the unfavourable acoustic signature. The unfavourable acoustic signature will be understood by the skilled addressee to be the acoustic signature associated with the first noise source that comprises acoustic characteristics that have exceeded the predetermined threshold requirement. In this way, the controller may identify unique acoustic signatures associated with the first noise sources with acoustic characteristics that exceed the predetermined threshold requirement.

Preferably, the movable barrier actuating system further comprises a second microphone configured to detect a second noise level associated with the second environment and transmit, via a second transmitter, a second noise level signal representative of the second noise level to the controller.

Preferably, the controller ceases transmitting the actuation signal in response to the second noise level signal meeting an ambient soundscape threshold. The ambient soundscape threshold will be understood by the skilled addressed to be an acoustic characteristic threshold associated with the second noise level. In preferable embodiments, the ambient soundscape threshold is a minimum amplitude threshold such that the ambient soundscape amplitude reduces in magnitude and meets the minimum amplitude threshold. In this way, when the amplitude of the second noise level signal is lower than the minimum amplitude threshold, the controller will stop transmitting the actuation signal such that the movable barrier is no longer actuated.

Preferably, the controller is in communication with a centralised unfavourable acoustic signature database configured to store unfavourable acoustic signatures, wherein the centralised unfavourable acoustic signature database comprises a learning module configured to identify unfavourable acoustic signatures based on one selected from the range of: the continuous acoustic noise spectrum exceeding the predetermined threshold or feedback from the second noise level signal. The unfavourable acoustic signature will be understood by the skilled addressee to be the acoustic signature associated with the first noise source comprising an amplitude exceeding the predetermined amplitude threshold.

Further examples of unfavourable acoustic signatures include acoustic signatures associated with first noise sources comprising a frequency exceeding a predetermined frequency threshold or any other acoustic characteristic exceeding a predetermined characteristic threshold. In this way, a first noise source that is too loud (i.e. exceeds the predetermined amplitude threshold) will have its associated acoustic signature stored in a centralised database of unfavourable noises. Further, the centralised unfavourable acoustic signature database may be updated as additional unfavourable noises are detected by the first microphone corresponding to additional first noise sources.

Preferably, the controller is further configured to transmit the actuation signal to the movable barrier actuator in response to receiving an acoustic signature that matches an unfavourable acoustic signature. In this way, the controller may match the acoustic signature of the real time continuous acoustic spectrum with a corresponding acoustic signature stored in the centralised unfavourable acoustic signals database. Further, the controller may transmit the actuation signal before the acoustic characteristic exceeds the predetermined threshold requirement such that the actuation signal is sent proactively.

Preferably, the movable barrier actuating system further comprises a plurality of first microphones, a plurality of second microphones and a plurality of movable barrier actuators.

In this way, multiple locations may be covered and first microphones may be used to measure the real-time acoustic spectrum of the fist noise, multiple second microphones may be used to measure the second noise level of the second environment, and multiple movable barrier actuators may be used to actuate movable barriers.

Preferably, each of the plurality of first microphones is configured to cover one or more zones of the first environment. In this way, real-time acoustic spectrums originating from multiple first environment zones may be measured.

Preferably, each of the plurality of second microphones is configured to cover one or more zones of the second environment. In this way, each of the second microphones may cover more than one area of the second environment.

Preferably, each of the plurality of movable barrier actuators correspond to a predetermined movable barrier. In this way, each movable barrier actuator may actuate a unique movable barrier.

Preferably, each of the plurality of movable barriers correspond to one of the zones of the first environment. In this way, when one of the movable barriers is actuated, the real time continuous acoustic spectrum originating from the corresponding zone of the first environment may be attenuated.

Preferably, the controller comprises: a microcontroller; a processor; at least one input port arranged to facilitate the transfer of the first real time noise spectrum from the plurality of first microphones and the second noise signal from the plurality of second microphones; at least one output port arranged to connect the controller to all first microphones, all second microphones and all movable barrier actuators; and a data connection. In this way, each of the first microphones, each of the second microphones and each of the movable barrier actuators are controlled by a single, central controller.

Preferably, the plurality of first microphones comprise protective features selected from the range of: heat/cold protection; weather protection; cover; or waterproofing. In this way, the first microphones are protected from sources of damage or interference such as wind and rain. Further examples of sources of damage may exist.

Preferably, the processor is configured to perform a noise signal filtering algorithm. In this way, the processor may filter out acoustic signals originating from ambient noise sources such as rain or wind. Further examples of ambient noise sources may exist.

Preferably, the input ports are further arranged to provide an input to the controller from any one selected from the range of: a temperature sensor; a CO2 sensor; a humidity sensor; an occupancy sensor; a rain sensor; and a wind sensor. In this way, the present invention may be incorporated into a composite CO2, temperature, humidity and noise controlling product.

Preferably, there are a plurality of systems in communication with the centralised unfavourable acoustic signature database. In this way, additional separate systems may all 35 contribute to building the unfavourable acoustic signature database such that an unfavourable acoustic signature detected on a first system may be used to cause the controller comprised in a second system to proactively transmit the actuation signal despite the unfavourable acoustic signature having never been detected before.

Preferably, the controller further comprises a threshold module configured to generate the predetermined threshold requirement. Preferably, the predetermined threshold requirement is generated based on a first environment ambient soundscape.

In accordance with a second aspect of the invention, there is provided a movable barrier actuating method for providing noise mitigation between a first environment and a second environment, wherein the method comprises the steps of: detecting, using a first microphone, a first noise source originating from the first environment, the first noise source comprising an acoustic signature and acoustic characteristics; transmitting, from a transmitter to a controller, a first real-time acoustic spectrum representative of the first noise source; identifying, using the controller, that the acoustic characteristics exceed a predetermined threshold requirement; transmitting, from the controller to a movable barrier actuator, an actuation signal; and actuating, using the movable barrier actuator, a movable barrier upon receipt of the actuation signal such that that the movable barrier is caused to move and the first noise source is attenuated such that the second environment is quieter.

Preferably, the movable barrier actuating method further comprises the steps of: connecting, via a data connection, the controller to a centralised unfavourable acoustic signature database; sending, from the controller to the centralised unfavourable acoustic signature database, the acoustic signature; identifying, using a learning module, unfavourable acoustic signatures that correspond to acoustic signatures associated with first noise source signals comprising acoustic characteristics that exceed the predetermined threshold requirement; sending, from the centralised database to the controller, unfavourable acoustic signatures; and identifying, using the controller, acoustic signatures that match unfavourable acoustic signatures such that the controllers can recognise unfavourable signatures from the corresponding first environments and proactively send the actuation signal to the corresponding movable barrier attenuator.

Preferably, the movable barrier actuating method further comprises the steps of: detecting, using a second microphone, a second noise level associated with the second environment; sending, via a second transmitter to the controller, a second noise signal representative of the second noise level; and terminating, using the controller, the actuation signal if the second noise signal meets a predetermined soundscape threshold.

Referring to FIG. 1, a perspective view of the movable barrier actuating system 100 according to the first aspect of the present invention is shown. In the example shown, there is a building 102 comprising a number of walls w', w". The wall w' comprises an exterior face 108 and the wall w" comprises an exterior face 130. The building 102 further comprises, a number of rooms 112, 128, a number of movable barriers 104, 114, 118, 122, the movable barriers 104, 114, 118, 122 being windows 104, 114, 118, 122, a number of first microphones 132, 134, the first microphones 132, 134 being external microphones 132, 134, a number of second microphones 136, 138, the second microphones 136, 138 being internal microphones 136, 138, and a controller 140.

A first external microphone 132 is located on an external face 108 of wall W'. The first external microphone 132 comprises a first transmitter.

A second external microphone 134 is located on an external face 130 of wall W". The second external microphone comprises a second transmitter.

A second internal microphone 138 is located on an internal face of the second room 128. The second internal microphone comprises a fourth transmitter.

The controller 140 is arranged in digital communication with the first window actuator 106, the second window actuator 116, the third window actuator 120, the fourth window actuator 124, the first external microphone 132, the second external microphone 134, the first internal microphone 136 and the second internal microphone 138.

A second external source 144 comprises a second amplitude and a second acoustic signature. The second external microphone 134 is arranged along the axis 126 to collect the component of the second external source 144 propagating along the axis 126.

The movable barrier actuating system 100 further comprises a central database 146 in digital communication with the controller 140.

In a further embodiment, multiple systems 100 are in communication with the central database 146.

Turning now to FIG. 18, there is shown a schematic view 150 of the movable barrier actuating system 100 in accordance with the first aspect of the present invention as shown in FIG. 1A. The first external microphone 132 comprises a first transmitter 152 in digital communication with the controller 140. The second external microphone 134 comprises a second transmitter 154 in digital communication with the controller 140. The first internal microphone 136 comprises a third transmitter 156 in digital communication with the controller 140. The second internal microphone 138 comprises a fourth transmitter 158 in digital communication with the central controller 140.

The controller is in further digital communication with the first window actuator 106, the second window actuator 116, the third window actuator 120, the fourth window actuator 124 and the central database 146 In use and with reference to FIG. 2, for the first room 112, the first external microphone 132 detects 202 the first amplitude and first acoustic signature of the first external source. In addition, the second external microphone 134 detects 202 the second amplitude and second acoustic signature of the second external source.

The first transmitter transmits 204 the first amplitude and first acoustic signature to the controller 140. The second transmitter transmits 204 the second amplitude and second acoustic signature to the controller 140.

Simultaneously, the first internal microphone 136 detects 222 a first ambient noise amplitude and the third transmitter transmits 224 the first ambient noise amplitude to the controller 140.

The controller 140 identifies 206 that the first amplitude has exceeded a first amplitude threshold. Further, the controller 140 compares the second amplitude to a second amplitude threshold.

If the first amplitude exceeds the first amplitude threshold, the controller transmits 208 a first actuation signal to the first window actuator 106. If the second amplitude exceeds the second amplitude threshold, the controller 140 transmits 208 a second actuation signal and a third actuation signal to the second window 114 and third window 118 respectively.

Upon receipt of the first actuation signal, the first window actuator 106 begins to actuate 210 the first window 104 such that the first window 114 extends a reduced distance along the axis 110.

Upon receipt of the second actuation signal, the second window actuator 116 begins to actuate 210 the second window 114 such that the second window 114 extends a reduced distance along the axis 110.

Upon receipt of the third actuation signal, the third window actuator 120 begins to actuate the third window 118 such that the third window 118 extends a reduced distance along the axis 110 Simultaneously, the controller 140 identifies 220 that the first ambient noise amplitude has reached a first ambient noise threshold. If the first ambient noise amplitude is less than the first ambient noise threshold, then the controller 140 will terminate 226 the transmission of the first actuation signal, the second actuation and the third actuation signal such that the first window 104, the second window 114 and the third window 118 no longer close and ventilation is still possible.

In use for the second room 128 and with reference to FIG. 2, the second external microphone 134 detects 202 the second amplitude and the second acoustic signature of the second external source 144.

The second transmitter transmits 208 the second amplitude and second acoustic signature to the controller 140. Simultaneously, the second internal microphone 138 detects 222 a second ambient noise amplitude and the fourth transmitter transmits the second ambient noise amplitude to the controller 140.

The controller 140 compares the second amplitude to the second amplitude threshold. If the second amplitude exceeds the amplitude threshold, the controller transmits a fourth actuation signal to the fourth window actuator 124.

Upon receipt of the fourth actuation signal, the fourth window actuator 124 begins to actuate 210 the fourth window 122 such that the fourth window 122 extends a reduced distance along the axis 126.

Simultaneously, the controller 140 identifies that the second ambient noise amplitude has reached a second ambient noise threshold. If the second ambient noise amplitude is less than the second ambient noise threshold, then the controller 140 will terminate 226 the transmission of the fourth actuation signal such that the fourth window 122 no longer closes along the axis 126 and ventilation is still possible.

The controller 140 sends 214 all external noise signatures, as well as noise amplitudes corresponding to said noise signatures to the central database 146 via a data connection 148.

The central database 146 stores all external noise signatures. The central database 146 further comprises a self-learning module 147. The self-learning module 147 will identify 206 all noise signatures that have a corresponding noise amplitude exceeding the noise amplitude threshold as a disruptive noise signature. The central database 146 sends 218 the disruptive noise signatures to the controller 140. If an acoustic signature originating from one of the external sources 142, 144 is detected 202 by one of the external microphones 132, 134 and is identified 220 by the controller 140 as matching one of the disruptive noise signatures, the controller 140 will transmit 208 the actuating signal to the windows 104, 114, 118, 122 corresponding to the external source 142, 144. This may occur before the external noise source 142, 144 exceeds the predetermined amplitude threshold.

Turning now to FIG. 3, there is shown a visual description of an example ambient soundscape and threshold generation algorithm.

A threshold module comprised in the controller 140 generates a first environment ambient soundscape corresponding to the first environment. In this embodiment, the first environment ambient soundscape is an external ambient soundscape and the first environment is an external environment. The external ambient soundscape is generated by generating a running mean value Ama of amplitudes AA over a time period T. A predetermined amplitude threshold Ame is generated based on the running mean value Am.. An external amplitude limit ALe is generated based on the running mean value Ama.

In use, an external noise source 142 generates an amplitude AT over the time period T. At time Ti, the amplitude AT of the external noise source 142 exceeds the predetermined amplitude threshold Ame. The controller 140 transmits the actuation signal to the window actuator 106 such that the window 104 begins to actuate. At time -12, the amplitude AT of the external noise 142 meets the external noise limit ALe, at which point the window 104 is fully actuated. At time T3, the amplitude AT of the external noise source 142 has reduced to below the external amplitude limit ALe, at which point the controller 140 begins to transmit the actuation signal such that the window 104 begins opening.

Peaks in frequency that don't cause the overall amplitude AT to exceed the predetermined amplitude threshold Am or the external amplitude limit ALe will still cause the controller 140 to transmit the actuation signal if the frequency exceeds a predetermined frequency threshold (not shown) which will be greater for the lower and higher ends of the frequency spectrum.

All external noise sources 142, 144 that have instances of the amplitude AT exceeding the predetermined amplitude/frequency threshold will have their acoustic signatures recorded and stored within the centralised unfavourable acoustic signature database 146.

The acoustic signature of the external noise source will always be compared against all unfavourable acoustic signatures stored within the centralised unfavourable acoustic signature database. If the signatures match, then the controller 140 will transmit the actuation signal as per the previous iteration of the acoustic signature.

The internal microphone 136 refines the controller 140 reaction by providing a feedback loop so as to indicate the impact of the externally measured noise source 142.

It will be appreciated that the above-described embodiments are given by way of example only and that various modifications may be made to the described embodiments without departing from the scope of the invention as defined by the appended claims. For example, the described embodiments refer to the amplitude and acoustic signature of the noise source but these are interchangeable with any other acoustic wave properties, such as frequency or direction. In addition, whilst the above embodiments describe a single sound source corresponding to each wall, there may be significant overlap between the sources or there could be multiple sound sources corresponding to each wall. Further, there could be any number of components.

It will be appreciated by the skilled addressee that the method steps outlined above describe a single noise source, a single window and a single window actuator and the method may be used for a plurality of windows/ hatches/ openings bounded by doors, window actuators and noise sources.

It will be appreciated by the skilled addressee that the window movement/actuation could be closely related in time, together or simultaneously.
