Some embodiments relate to an apparatus for the monitoring of at least one thermal control device in the interests of reducing its energy consumption, and to an associated control unit and control system. Some embodiments specifically relate to the optimized control of devices for the heating or management of hot water in residential buildings.
The energy consumption of devices for the heating and management of hot water accounts, on average, for over 60% of the total energy consumption of a residential building.
In order to reduce the energy consumption of these thermal control devices, and consequently their associated costs, a number of solutions have been developed.
These related solutions include control apparatuses comprising a central thermostat connected to a remote server via a communication network. The thermostat is equipped with a temperature sensor and a memory for the storage of a software application. Conventionally, the thermostat is designed to switch the heating devices in a central heating system between a “comfort” mode and an “economy” mode, or for the control thereof in relation to a plurality of setpoint temperatures, within time intervals which are predefined by a user. The thermostat is also designed, by means of the temperature sensor, for the regulation of the heating temperature in relation to a predefined setpoint temperature. A user can then connect to the network which communicates with the thermostat using a mobile communication device and, by means of the remote server, can select the setpoint temperature to be set on the thermostat. Finally, by means of its software application, a thermostat of this type is capable of learning the habits of the user, in terms of temperature settings, thereby permitting the regular optimization of heating time intervals and heating times in respect of desired temperature levels, in order to reduce the energy consumption of heating devices.
However, a control apparatus of this type does not permit the control of a decentralized heating system comprised, for example, of a series of radiators in a residential building. Another disadvantage is that the reduction in the energy consumption of heating devices is not known and, in consequence, is not optimal. Moreover, on the grounds of the centralized measurement of temperature and the occurrence of disparities in temperature within the residence, only the room in which the thermostat is located is exactly controlled to the desired setpoint temperature. This results in problems in the control of heating within the residence, such as rooms which are excessively hot or excessively cold for the residents.
Other systems for the reduction of the energy consumption of thermal control devices are proposed by operators, involving the deployment of the consumption cut-off principle. More specifically, systems of this type comprise an electronic console arranged within the residence. The electronic console is connected firstly to a communication network which is external to the residence, and secondly to the electric power supply system of the thermal control devices. Accordingly, the operator of the energy cut-off service can, by means of the communication network and the electronic console, momentarily interrupt the electric power supply to a number of high-consuming heating devices, for example in order to prevent peaks in energy consumption, or to permit the client of the service to enjoy the optimum exploitation of reduced tariff time intervals.
A disadvantage of systems of this type is their inability to regulate heating in relation to a setpoint temperature.
A related art solution for overcoming this disadvantage is proposed in document EP 2953947, which describes an optimized control module for thermal control devices. The control module comprises means for the transmission, to the thermal control devices to which it is connected, of a signal for the activation and/or deactivation of the devices, means of determination which are designed to determine, for each device to be regulated, an activation time for the device as a function of an estimated temperature setpoint value, and means for the measurement of temperature. In the invention disclosed by this document, the energy cut-off time dictated by the control module is determined as a function of a temperature interval based around the selected setpoint temperature, in order to offset the cut-off in terms of the comfort of the user.
However, the reduction in the energy consumption of heating devices achieved by a control module of this type is not known and, in consequence, is not optimal, specifically on the grounds that this reduction is executed from the viewpoint of the service operator. Moreover, a control method deployed using a control module of this type, whilst intended to ensure an acceptable level of comfort within the residence can, by very dint of the energy cut-off principle, result in situations in which the ultimate thermal comfort of the user is compromised.
The invention described hereinafter is intended to rectify all or part of the disadvantages of the prior art, specifically by the disclosure of an apparatus for the monitoring of at least one thermal control device for the purposes of the further reduction of the energy consumption of the, or of each thermal control device, whilst simultaneously permitting the control of centralized and decentralized thermal control systems, without impairing the ultimate thermal comfort of the user.

The command management module 76 is designed to receive and execute commands for the interruption of the electric power supply and/or regulating commands transmitted to the communication module 74. To this end, the command management module 76 is designed to deploy an algorithm which is capable of regulating the temperature on the associated thermal control device 10 by the integration of two restrictions: a priority restriction, provided by the energy consumption setpoint, and a secondary restriction provided by the temperature setpoint. Accordingly, the algorithm continuously monitors the priority restriction, and compares a measured temperature delivered by the temperature sensor with the setpoint temperature, in order to permit the closest possible tracking of the secondary restriction. In practice, the algorithm tracks the secondary restriction for such time as the energy quota delivered by the energy consumption setpoint is not consumed by the associated thermal control device 10.

As a variant or additionally, the calculation module 108 is designed to recommend a modification to the subscribed electric load demand of the user in their current electricity supply offer. More specifically, the calculation module 108 is designed, via the current sensors 31, to obtain real-time measured data 114 for the electric consumption of all the thermal control devices 10, to isolate from these data 114 those which measure a peak in consumption corresponding to a given period, typically in the winter season, and to verify whether this peak in consumption would be compatible or otherwise with an electric load demand which is lower than that subscribed by the user. If this compatibility is confirmed, the calculation module 108 can advantageously propose that the user switch their current electricity supply offer to an offer with a lower electric load demand. This automatic load-shedding operation permits an increase in the level of budgetary savings realized without compromising the comfort of the user and without jeopardizing the electrical installation of the facility.
As a variant or additionally, the calculation module 108 is designed to exploit, in the current electricity supply offer of the user, those time intervals which are subject to a lower tariff, also described as “off-peak hours”. For example, for each switchover to “comfort” mode anticipated in the time scheduling for the temperature of a thermal control device 10, the calculation module 108 is designed to determine whether or not it is cost-effective to supply the device 10 a little earlier, in order to benefit from “off-peak” hours, and thereafter to maintain the power supply to the device until the time of switchover to “comfort” mode initially scheduled. Where applicable, the calculation module 108 is moreover designed to transmit to the electronic console 26, prior to the initially-scheduled commencement of “comfort” mode, a corresponding electric power supply command instruction. This permits an increase in the level of budgetary savings achieved, without compromising the comfort of the user.
In the exemplary embodiment shown in
More specifically again, the generation module 110 is designed to assign to each filtered acoustic data element measured an indicative data element for the proportion of time during which sounds have been detected, relative to the total duration of measurement. For example, the generation module 110 is designed to assign to each filtered acoustic data element measured a data element from the group comprised of the following: a first indicative data element of a proportion of time equal to 10%, a second indicative data element of a proportion of time equal to 50%, and a third indicative data element of a proportion of time equal to 90%. Upon the comparison of each filtered acoustic data element measured with average minimum ambient noise:
The generation module 110 is also designed to generate the presence detection signal 112 upon the reception of the signal 101 of the detection of the opening of an opening element.
The computer 14 is connected to the control unit 12 via the communication network 17. The computer 14 is provided with data acquisition means 132. In the exemplary embodiment shown in
The user interface 134 is, for example, a touchscreen. The interface 134 specifically permits the display of at least one button for the setting of a temperature which is classified as the “comfort” mode temperature, and a temperature which is classified as the “economy” mode temperature. In a particular form of embodiment, the interface 134 may also display buttons for the setting of time schedules for temperature required by the user and/or a shutdown button for all the thermal control devices 10. Further to the activation of one of these buttons by the user, the computer 14 is designed to transmit a corresponding command signal to the server 24. This real-time transmission, in combination with real-time communication between the server 24 and the electronic console 26, permits the rapid incorporatioon of a user instruction, which is preferably implemented within a time interval equal to less than 5 seconds. Advantageously, the interface 134 permits the display, for each room in the premises 18, of a button for the setting of time schedules for temperature required and/or a shutdown button for the thermal control devices 10 in said room. This permits the fine control of the required temperature in each room of the premises 18. Advantageously again, the interface 134 permits the display of a field for the entry of textual data which are indicative of technical characteristics of the premises 18. The computer 14 is then able to transmit these data to the second database 16B, via the communication network 17. Advangtageously again, the interface 134 permits the display of the representative calibrated data element 124 for an energy saving and/or the first representative estimated data element 122 for the energy consumption of the device 10. The user is thus able to identify, in real time, the energy consumption of the thermal control devices 10 and/or the level of savings realized.
The application 136 is, for example, downloadable from the communication network 17. The application 136 comprises a module for the acquisition of representative data on user interactions with the premises 18. Such data can represent, for example, the presence or absence of the user in the premises 18. In this case, the interface 134 permits the display of buttons for the selection of a “present” mode or an “absent” mode. Such data can also indicate information on the opening of an opening element 34 by the user. In this case, the interface 134 permits the display of an indicator button for the opening of an opening element.
As a variant or additionally, the application 136 comprises a module for the acquisition of representative data on thermal sensations of a user within the premises 18. In this case, the interface 134 permits, for example, the display of buttons for the selection of a “cold” thermal sensation or a “hot” thermal sensation, corresponding to the thermal sensation of the user.
As a variant or additionally, the application 136 comprises a geolocation module which is designed to acquire data on the geographical position of the computer 14, for example, satellite data of the GPS type (GPS=Global Positioning System).
The user interface 134, or the web access interface in the case of a desktop computer or portable computer, are also designed to receive alerts generated by the application 26 on the server 24, and to deliver a visual representation of these alerts. The alerts are, for example, e-mail notifications or “push” notifications in the case of a wireless communication device. According to a specific exemplary embodiment, these alert functions comprise one or more buttons which permit a user, further to the selection of the button on the interface, to respond to information in real time. This permits an increase in the interactivity of the system. For example, if the device 33 detects the opening of the opening element 34, the server 24 transmits to the console 26 a command instruction for the shutdown of the thermal control devices 10. In practice, in this case, the opening of the opening element 34 may cause substantial thermal losses, resulting in unnecessary energy consumption. An alert is thus transmitted by the server 24 to the user via the interface 134 or via the web access interface. This alert indicates an opening of the opening element 34, and includes a button which permits the user to indicate whether they have closed the opening element 34. If the user indicates that they have closed the opening element 34, the time schedule for the temperature of the thermal control devices 10 is resumed on the associated control devices 30. Otherwise, the devices 10 will remain turned off, until such time as the acoustic detectors 32 detect a reduction in the sound level. The server 24 then transmits to the console 26 an instruction for the restarting of the thermal control devices 10 in accordance with the time schedule in force prior to the interruption in supply, and the intensity of current consumed is measured by the current sensors 31. The restarting function will be maintained in force if the current intensity value measured is equal to or lower than that measured at the time of detection of the opening of the opening element 34. The interactive alert transmitted for the attention of the user will then be replaced by an informative alert. Another example of an alert is the sending of an interactive alert to the user on the day before a public holiday, on Christmas or New Year's Eve, or the day before the start of the school holidays, if the user has children. In this case, the alert incorporates a button which, for example, permits the user to indicate if they will be absent on the following day and, if so, to indicate the duration of their scheduled absence.
Advantageously, the server 24 is designed, via the generation module 110 of the application 106, to generate the presence detection signal 112 as a function, in addition to the acoustic data 130 measured by each acoustic sensor 32 and the signal 101 for the detection of the opening of an opening element, of data acquired and/or geolocated by the computer 14.
Advantageously, the calculation module 108 is designed for the deduction, from data acquired and/or geolocated by the computer 14, of “logical” sequences for the presence and absence of a user over a given period of time (for example, if a user indicates, via the interface 134, a “cold” thermal sensation on the same day at an interval of one week, the calculation module 108 will deduce a potential requirement for the adjustment of the time schedule such that the user will no longer feel cold on the same day in subsequent weeks, and transmits a message to the application 106 of the computer 14 to alert the user, and establish whether the latter actually wishes to modify the time schedule for this day of the week, or whether the indication of the relevant thermal sensation was exceptional. If the user accepts the proposal, the calculation module 108 is designed to apply the new time schedule).
The server 24 is moreover designed to generate command instructions 36 for each thermal control device 10, as a function of parameters comprising, moreover, data acquired by the computer 14. Data acquired by the computer 14 comprise at least a indicative data element 114 for a restriction of energy consumption. For example, this data element 114 may take the form of a numerical data element which is representative of a monthly or annual energy budget which is not to be exceeded. As a variant, this data element 114 may take the form of a quantified target for budgetary savings to be realized. In both cases, the interface 134 permits the display of a field for the entry of a numerical data element by a user. As a further variant, the user enters no numerical data in the interface 134, and the data element 114 assumes an “infinite” value, indicating that no restriction on energy consumption is imposed by the control unit 12. In this case, the calculation module 108 of the server 24 determines and allots, for each control device 30, and energy quota having an “infinite” value.
In practice, further to the entry thereof by the user in the interface 134, the data element 114 is transmitted by the computer 14 to the server 24 via the communication network 17, and the calculation module 108 of the application 106 determines the energy consumption setpoint for each thermal control device 10 as a function of the value of this data element 114, a history of temperature data 116 measured within the premises 18, a history of seasonal climatic or temperature data 118, and a history of data 122 representative for energy consumption. The calculation module 108 also determines the temperature setpoint on each thermal control device 10, and command instructions 36 are then transmitted by the server 24 to the electronic console 26, for deployment by the control devices 30. Each measuring element 31 measures a representative variable of energy consumption, typically the intensity of an electric current, and delivers measured data 126 to the server 24. As each measuring element 31 is arranged within a control device 30, each control device 30 is thus able to verify, in the course of the application of the temperature setpoint, that the energy quota allotted by the energy consumption setpoint is not exceeded by the measured value of the representative variable for energy consumption. If, on each control device 30, the measured value achieves a predetermined percentage of the allotted energy quota, for example a percentage substantially equal to 90%, the control devices 30 notify the server 24, and the server 24 transmits to the console 26 a command instruction for the shutdown of certain thermal control devices 10, in a predetermined order. For example, priority may be assigned to the device 10 situated in a “living” room, during the daytime. This permits the continuous regulation of the thermal comfort of the user as a function of energy consumption, and the adjustment of periods of comfort in accordance with strict necessity.
Advantageously, the generation module 110 is also designed to generate the presence detection signal 112 upon the reception of data on the geographical position of the computer 14, acquired by the computer 14 and then transmitted to the server 24, indicating that the computer 14 is situated on the interior of the premises 18. Further advantageously, the generation module 110 is designed to generate the presence detection signal 112 upon the reception of representative data for the thermal sensations of a user within the premises 18, or data indicating an opening of the opening element 34 by the user, or data indicating a modification to the time schedule for temperature required by the user, wherein said data are acquired by the computer 14, then transmitted to the server 24.
Advantageously, the generation module 110 is also designed to generate an absence signal if:
It will thus be understood that the control apparatus 22 according to the invention permits the further reduction of the energy consumption of each thermal control device 10, without affecting the ultimate thermal comfort of the user. Moreover, the control system 1 according to the invention permits, by the deployment of concentric “intelligent” blocks formed by the network of devices 30 for the control of the thermal control system, by the electronic console 26, by the server 24 and by the computer 14, the achievement of a further increase in the reduction of the overall level of energy consumption, and thus in the level of budgetary savings realized.
In this variant of embodiment, two thermal control devices 150A, 150B are represented. A first thermal control device 150A comprises an electric power supply input terminal 20 which is designed for connection to an electric power supply source. The first thermal control device 150A is, for example, a gas boiler, which supplies a second thermal control device 150B, for example a thermal radiator, via the circulation of hot water. According to this variant of embodiment of the invention, the combination of thermal control devices 150A, 150B forms a central heating system.

The application 106 of the server 24 comprises, in addition to the calculation module 108 and the module 110 for the generation of a signal 112 for the detection of the presence of a user in the premises 18, a zoning module 152. The memory 104 of the server 24 moreover comprises a decision-making table 153.
According to the variant of embodiment illustrated in
The zoning module 152 is designed to divide the premises 18 into a number of predetermined zones, wherein each zone comprises at least one temperature sensor 28. In the exemplary embodiment shown in
The inputs of the decision-making table 153 are the time scheduling data for temperature in each predetermined zone 154A, 154B, wherein said data are delivered by the calculation module 108. The output of the decision-making table 153 is a command signal for the priority execution of the time schedule in one of the predetermined zones 154A, 154B. The priority execution command signal is designed for transmission to the control apparatus 22 via the communication network 17, and is determined by the deployment of a decision-making algorithm. The decision-making algorithm of this type is given, for example, by the following sequence:
Advantageously, the zoning module 152, in association with the decision-making table 153, permits the effective resolution of the issue of the excessively hot or excessively cold room in a centralized thermal control system of the type represented in
As the remainder of the operation of the control system according to the variant of embodiment illustrated in
It will thus be understood that the control apparatus 22 according to the invention moreover permits the control of both centralized and decentralized thermal control systems.
According to a second aspect of the invention, which is complementary to, but independent of the first aspect, the invention also relates to a device for the detection of the presence of a user in at least one room of the premises 18. The presence detection device comprises at least one acoustic sensor 32 and a server 24, wherein the or each acoustic sensor 32 is arranged within the premises 18. The server 24 is connected to the or each acoustic sensor 32 via a communication network 17. In a specific exemplary embodiment, the or each acoustic sensor 32 is connected to the communication network 17 via an electronic console 26 which is connected to a terminal box 35, wherein the terminal box 35 provides access to a high-capacity data communication link incorporated in the network 17, for example a high-capacity Internet link. The electronic console 26 and the terminal box 35 are, for example, arranged within the premises 18.
According to this specific exemplary embodiment, each acoustic sensor 32 is designed to communicate with the electronic console 26 via a data link 90. Each acoustic sensor 32 is designed to deliver measured acoustic data, and to transmit said data on the data link 90. The electronic console 26 is designed to transmit to the server 24, via the terminal box 35 and the communication network 17, acoustic data measured by each acoustic sensor 32.
Each data link 90 is a wired link or a wireless link. In a preferred form of embodiment, each data link 90 is a wireless radioelectric link, for example a radioelectric link in compliance with IEEE standard 802.15.4 (Zigbee protocol), or a radioelectric link employing a frequency band which substantially encompasses a central frequency equal to 868 MHz.
Each acoustic sensor 32 comprises a microphone 92, an amplifier 94, a filter 96 and a transmitter 98.
The output of the microphone 92 is connected to the input of the amplifier 94. The microphone 92 has a bandwidth substantially within the range of 100 Hz to 3500 Hz. The microphone 92 is, for example, a condenser microphone.
The output of the amplifier 94 is connected to the input of the filter 96 and to the input of the transmitter 98. The amplifier 94 is, for example, a staged amplifier.
The output of the filter 96 is connected to the input of the transmitter 98. The filter 96 is, for example, a band-pass filter having a bandwidth substantially within the range of 100 Hz to 250 Hz.
The server 24 comprises, for example, a processor 102 and a memory 104 connected to the processor 102. The memory 104 stores an application 110 which is designed for deployment by the processor 102. The application 110 is designed, upon the deployment thereof by the processor 102, to generate a signal 112 for the detection of the presence of a user within the premises 18, as a function of the acoustic data measured by each acoustic sensor 32.
More specifically, the application 110 is designed to calculate, from the measured acoustic data amplified by the amplifier 94 on each acoustic sensor 32, an average acoustic energy value over a predetermined time interval. This calculation of an average acoustic energy value may be executed, for example, on a daily basis, wherein the predetermined time interval is equal, for example, to one hour. The application 110 is also designed to calculate the average minimum ambient noise in an iterative manner. This average minimum ambient noise is obtained by the averaging of each new average acoustic energy value calculated with a historic mean of the average acoustic energy values previously calculated. This calculation of the average minimum ambient noise is executed, for example, on a daily basis. The application 110 is moreover designed to undertake the periodic comparison of each measured acoustic data element, filtered by the filter 96 of one of the acoustic sensors 32, with the average minimum ambient noise, and to generate the presence detection signal 112 as a function of the result of this comparison. More specifically, the result of this comparison may be the detection of a human noise, and the application 110 is designed to generate the presence detection signal 112 in response to each human noise detected.
More specifically again, the application 110 is designed to assign to each filtered acoustic data element measured an indicative data element for the proportion of time during which sounds have been detected, relative to the total duration of measurement. For example, the application 110 is designed to assign to each filtered acoustic data element measured a data element from the group comprised of the following: a first indicative data element of a proportion of time equal to 10%, a second indicative data element of a proportion of time equal to 50%, and a third indicative data element of a proportion of time equal to 90%. Upon the comparison of each filtered acoustic data element measured with average minimum ambient noise:
The presence detection device according to the second aspect of the invention permits the accurate detection of one or more human voice(s) in the premises 18, and the deduction therefrom of the presence of a user, by means of components which are inexpensive to manufacture. The presence detection device according to the second aspect of the invention thus permits the achievement of the effective detection of the presence of a user within the premises 18, whilst reducing costs.
According to a third aspect of the invention, which is complementary to, but independent of the first and second aspects, the invention also relates to a method for the installation within premises 18 of an apparatus 22 for the monitoring of at least one thermal control device 10, 150A, 150B. The control apparatus 22 is that described in the aforementioned form of embodiment, in which the electronic console 26 is equipped with a radio-tag 41, and each control device 30 is equipped with a female connector 61A and a radio-tag 70.
The installation method is illustrated in
Subsequently to, or in tandem with the initial step 170, the electric power supply to the or each thermal control unit 10, 150A is turned off in a step 172, for example by means of an intervention on the electric switchboard of the premises 18.
In a subsequent step 174, each cable connecting an electric power supply input terminal 20 of a thermal control device 10, 150A to an electric power source is physically separated, thus forming two cable strands.
In a subsequent step 176, for each cable separated in step 174, a male plug 61B is connected to the free end of each of the two cable strands.
In a subsequent step 178, an equal number of devices 30 for the control of the electric power supply are provided to the number of control devices 10, 150A to be controlled. Each male plug 61B is then connected to one of the female connectors 61A, such that each device 10, 150A to be controlled is associated with a control device 30. In the first exemplary embodiment illustrated in
In a subsequent step 180, the radio-tag 41 of the electronic console 26 is scanned, for example using a radio-tag reader device. The reading by the device of the identifier stored in the radio-tag 41 initiates a connection with a server which hosts a web application. The reader device then displays an interface which is linked to the web application and which permits the input of data relating to the premises 18. Data of this type are then entered on the interface of the reader device, thus permitting the pairing of the console 26 with the premises 18.
In a final step 182, the radio-tag 70 of each control device 30 is scanned, for example using a radio-tag reader device. The reading by the device of the identifier stored in each radio-tag 70 initiates a connection with a web server which hosts a web application. The reader device then displays an interface which is linked to the web application, and which permits the input of data relating to the room in which the associated thermal control device 10, 150A is installed, and data relating to the electrical capacity of said device 10, 150A. Data of this type are then entered on the interface of the reader device, thus permitting the pairing of each control device 30 with the console 26. More specifically, the server hosting the web application is, for example, the server 24, and the server 24 is designed to generate the pairing table from the data entered, and to transmit the pairing table thus generated to the electronic console 26. After pairing with the electronic console 26, the control devices 30 are designed to automatically transmit their respective identifiers to the console 26 in order to construct a local network of control devices.
The installation method according to the third aspect of the invention permits the reduction of the installation time for the control apparatus in the premises, and facilitates said installation, in comparison with the installation methods from the prior art.
