Description

Title of the invention: Communication system for at least one electrical device connected to an electrical network Field of invention

[0001] The present invention relates to a communication system for at least one electrical device connected to an electrical network. Prior art

[0002] It is known to use an electric meter with a communicating output. This communicating output is also called a customer information output or TIC.

[0003] The communicating output emits, at regular intervals, an input signal which can be used by electrical equipment of an installation including the electric meter.

[0004] The input signal may for example include a consumption index indicating peak and off-peak hours, a current tariff period, the subscribed intensity, the instantaneous consumption intensity, maximum intensity since the last reset, etc.

[0005] This arrangement is satisfactory in that it is possible to recover the input signal and use the information it contains to control certain electrical equipment. For example, it is possible to configure a water heater so that it starts up during off-peak hours.

[0006] The information contained in the output signal can be expressed according to a first communication protocol called historical mode. However, a second communication protocol called standard mode was subsequently introduced, the latter including more information.

[0007] To retrieve and interpret the output signal, it is necessary to know whether the output signal is expressed according to the first communication protocol or according to the second communication protocol.

[0008] Furthermore, some electrical equipment, older or of simpler design, is only compatible with the historical mode. There is therefore a difficulty in making electrical equipment operating in different modes with the same output signal in a given mode coexist within the same installation.

[0009] The present invention aims to resolve all or part of the drawbacks mentioned above. Statement of the invention

[0010] To this end, the present invention relates to a communication system for at at least one electrical device connected to an electrical network, the communication system comprising:

[0011] an input configured to receive an input signal emitted by a communicating output of an electric meter of an installation comprising at least one electrical equipment,

[0012] at least one output configured to emit at least one corresponding output signal to the at least one electrical device, said output signal comprising at least one control information capable of being interpreted by the at least one electrical device,

[0013] a processing unit configured to determine whether the input signal is according to a first communication protocol or according to a second communication protocol, the processing unit being configured to recognize, in the input signal, at least one operating indication relating to the at least one electrical equipment and / or to the electrical network, the processing unit being configured to develop the at least one output signal as a function of said at least one operating indication.

[0014] It appears that the communication system can receive an input signal according to two different communication protocols. The communication system recognizes the communication protocol used and retrieves the information it contains: the operating indications.

[0015] The communication system then produces one or more output signals, each output signal being intended for an electrical device with at least one piece of control information interpretable by the electrical device.

[0016] The communication system is thus an element of an installation arranged between the electricity meter and the electrical equipment(s) with the aim of communicating interpretable information to each electrical equipment, regardless of whether the input signal from the electricity meter is according to the first communication protocol or according to the second communication protocol.

[0017] Thus, depending on the scenario, not only does the communication system read the input signal and develop one or more control information items on this basis, but it also emits each output signal in a particular format adapted to a particular piece of electrical equipment.

[0018] According to one aspect of the invention, the communication system comprises a visual indicator configured to display whether the input signal is according to the first communication protocol or according to the second communication protocol.

[0019] Preferably, the visual indicator is in the form of two LEDs arranged to light up for the purpose of informing a user of the communication system.

[0020] According to one aspect of the invention, the communication system comprises a housing adapted to receive the processing unit, one input and at least one output.

[0021] Preferably, the input and the at least one output are sockets suitable for a wired connection. Alternatively, the input is an input for receiving a wireless signal, for example from a dedicated adapter mounted on the communicating output of the electricity meter.

[0022] According to another alternative, at least one output may be a transmitter of a wireless signal to electrical equipment suitable for receiving this type of signal.

[0023] In this text, "wireless" means remote communication by modulated electromagnetic waves. For example, it may be Bluetooth, low energy Bluetooth or BLE, Wi-Fi, mobile networks, satellites, etc.

[0024] According to one aspect of the invention, the processing unit is configured to determine whether the input signal is according to the first communication protocol or according to the second communication protocol by measuring a baud rate of the input signal.

[0025] This arrangement allows easy and rapid recognition of the communication protocol used.

[0026] The input signal is in the form of data frames. In particular, the transmission of frames takes place every two seconds. The first communication protocol, also called historical mode, has a baud rate of 1200. The second communication protocol, also called standard mode, has a baud rate of 9600.

[0027] In historical mode, the input signal includes as operating indications the consumption indexes of customer contracts, the current tariff period, the subscribed intensity, the instantaneous consumption intensity, the maximum intensity since the last reset, a warning of exceeding the subscribed power, a notice of start in 30 minutes of a period (depending on the contract).

[0028] The standard mode includes, in addition to the operating indications mentioned above, the following operating indications: the wording of the supplier index, the consumption indexes (10 indexes on the supplier grid, 4 indexes on the distributor grid), the cut-off power and the subscribed power, the instantaneous apparent power, the maximum power reached during the day and the day before, the last 2 points of the load curve, the start and end timestamp of the mobile peak, a short message (32 characters), the position of the 8 contacts (one dry contact and 7 digital).

[0029] Furthermore, if the customer is a producer, for example with electrical equipment being a photovoltaic panel, other operating indications are provided: the index of total injected active energy, 4 indexes of measurement of reactive energy, the instantaneous apparent power injected, the maximum apparent power injected reached during the day and the day before, the last 2 points of the injected active load curve.

[0030] Historical mode corresponds to the mode used by older residential electricity meters. If necessary, current electricity meters can be switched to this mode. Initially, this switch from standard mode to historical mode was carried out in installations whose electrical equipment was old and only accepted signals in historical mode.

[0031] By being inserted between the electric meter and the electrical equipment, the present communication system can be used with an input signal indifferently in historical mode or in standard mode.

[0032] Thus, if no adjustment is made at the level of the electric meter mode, this no longer poses an operating problem: the communication system integrates any type of input signal and translates it if necessary to each electrical equipment according to its specificities.

[0033] The work of the installer of new equipment is made easier. If recent equipment accepting signals in standard mode is installed, the meter can keep its setting in historical mode.

[0034] According to one aspect of the invention, the at least one output is of the unidirectional type or of the bidirectional type, a return signal from corresponding electrical equipment being capable of being received by the at least one bidirectional type output.

[0035] This arrangement makes it possible to provide in certain cases a simple sending of an output signal or a sending with waiting for a return signal. Depending on the electrical equipment, it may be useful to receive a return signal which is taken into account by the processing unit.

[0036] For example, for electrical equipment such as an electric car charger, it may be useful for the return signal to contain information on the quantity of energy remaining to be charged, a cut-off time at which charging must end, etc. The processing unit can then determine the output signal so as to respect the constraints of the charger and also the constraints known by the input signal.

[0037] According to one aspect of the invention, the communication system comprises a plurality of outputs each configured to emit a corresponding output signal to a corresponding electrical device, the plurality of outputs comprising at least one output configured to emit an output signal according to the first communication protocol, at least one output configured to emit an output signal according to the second communication protocol and / or at least one output configured to emit the output signal by switching a dry contact of said output.

[0038] The at least one output mentioned above corresponds to the plurality of outputs mentioned here. Each output emits an output signal according to a unique format. This may be the first communication protocol, the second communication protocol or a switching of a dry contact.

[0039] This arrangement allows easy connection of electrical equipment. Electrical equipment whose compatibility is known can be connected to the corresponding output.

[0040] Preferably, the at least one output configured to transmit according to the first communication protocol is of the unidirectional type and the at least one output configured to transmit according to the second communication protocol is of the bidirectional type.

[0041] Indeed, the second communication protocol being more recent, it is adapted to electrical equipment itself recent which is capable of emitting return signals.

[0042] However, alternatively, it is possible to provide only unidirectional or bidirectional type outputs for both the first communication protocol and the second communication protocol.

[0043] Furthermore, the dry contact switching outputs are of the relay closing and opening type to start or stop certain electrical equipment. These are outputs of simple construction.

[0044] Furthermore, it is possible to provide at least one output adapted to emit an output signal according to a third communication protocol different from the first communication protocol and the second communication protocol.

[0045] For example, the third communication protocol may be the OCCP language which is suitable for electric car chargers.

[0046] The communication system may also include one or more connectors to be attached to an output or bus to connect the communication system to particular electrical equipment.

[0047] According to one aspect of the invention, the communication system comprises a first data transfer bus including the at least one output configured to emit an output signal according to the first communication protocol and / or comprising a second data transfer bus including the at least one output configured to emit an output signal according to the second communication protocol.

[0048] Thus, having two separate buses makes it easier to connect electrical equipment.

[0049] Alternatively, only one bus may be provided, each output of the bus being configurable to transmit according to the first communication protocol or according to the second communication protocol.

[0050] According to one possibility, the first data transfer bus is of the unidirectional type. This type of bus is suitable for electrical equipment consuming electricity to operate, such as a water heater, electric heating or air conditioning. In this case, the unidirectional bus is suitable because it is not necessary to have feedback to the communication system.

[0051] An output according to the second communication protocol is for example included in a bidirectional data transfer bus. It may be an RJ45 connection or equivalent suitable for bidirectional data transfer.

[0052] The communication system may also include one or more connectors to be attached to an output or bus to connect the communication system to particular electrical equipment.

[0053] According to one aspect of the invention, the at least one piece of control information corresponds to the at least one operating indication and / or to at least one start-up instruction, one stop instruction, one power reduction instruction in a determined proportion.

[0054] It appears that the processing unit can provide several different responses following its programming. It is thus possible to prioritize certain electrical equipment such as heating or air conditioning and request to lower the power of others such as the electric car charger.

[0055] This arrangement is useful when it is necessary to reduce the total power of the installation comprising several electrical devices.

[0056] According to one aspect of the invention, the processing unit is a programmable automaton, the processing unit comprising in memory a program for developing the at least one output signal as a function of the input signal.

[0057] This arrangement makes it possible to define the control information to be transmitted to electrical equipment according to the operating indication(s) received.

[0058] According to one aspect of the invention, the programmable controller is a microprocessor. Preferably, the programmable controller is provided with an initial program installed in the factory.

[0059] The processing unit also comprises in memory an input signal recognition module capable of determining the communication protocol used and a translation module configured to interpret the input signal and express the at least one output signal according to the correct format.

[0060] According to one aspect of the invention, the communication system further comprises a data exchange module designed to receive instructions for modifying the program and / or to transmit data from the memory of the programmable controller.

[0061] This arrangement allows for adaptation to the addition or removal of electrical equipment by configuring a previously unused output. Furthermore, if the func The information emitted by the electricity meter changes over time, which allows the communication system to be adapted.

[0062] According to one aspect of the invention, the data exchange module is wired. Alternatively or in addition, the data exchange module is wireless. It may be provided to use only one wireless communication module for all wireless data exchanges of the communication system. The same wireless module may then be able to communicate with the electricity meter, at least part of the electrical equipment and / or any other suitable external device.

[0063] The present invention also relates to a method of configuring a communication system as described above, the configuration method comprising the following steps:

[0064] have an installation comprising at least one electrical device, an electric meter and the communication system,

[0065] establishing communication between a terminal and the data exchange module of the communication system,

[0066] modify the program dedicated to the development of at least one output signal with the terminal, the program consisting of defining each control information intended for a determined electrical equipment as a function of the at least one operating indication.

[0067] This arrangement makes it possible to modify the way in which electrical equipment is controlled without having to modify the installation. The communication system does not have to be replaced: it is sufficient to update the program.

[0068] This arrangement is of interest when new electrical equipment is added to the installation.

[0069] According to one aspect of the invention, the terminal is capable of connecting to the data exchange module via a wired or wireless connection. Preferably, the terminal is a tablet, a computer, a telephone, or any other electronic device having a user interface.

[0070] When the installation includes several electrical devices, the definition of a set of corresponding control information makes it possible to define an overall operating scenario for the installation.

[0071] In other words, the program defines which electrical equipment has priority in its operation. For example, a heater can be defined as a priority because it must not be turned off even if the installation needs electrical power for other applications.

[0072] The program can define that on the contrary the water heater, even when it is in operation can be cut off by opening the corresponding dry contact if a more urgent need for energy is necessary.

[0073] The program can define that the electric car charger operates at full power during off-peak hours although a rise in current approaching the maximum current of the subscription can call for sending control information at reduced power.

[0074] All of these rules that emerge from the programming have multiple benefits: the user experience is improved because he does not see the electrical equipment that he considers to be a priority being limited in its operation.

[0075] The maximum intensity of the installation subscribed to by the user can be reduced. Indeed, the program can limit the concomitant use of numerous energy-hungry electrical devices. Also, savings can be made by choosing to operate certain electrical devices during off-peak hours.

[0076] According to one aspect of the invention, the modification of the program consists of entering on an interface of the terminal, for each electrical equipment of the installation, a condition of operation at full power, a condition of operation at reduced power in a determined proportion and / or a shutdown condition, said conditions being configured to apply to the operating indications of the input signal.

[0077] This arrangement allows, thanks to the terminal interface, to specify for each electrical equipment the operating restriction conditions. Preferably, this is a web interface.

[0078] A computer program product is thus described comprising code instructions arranged to implement the steps of the configuration method above when said program is executed by the terminal.

[0079] The terminal includes in memory the code instructions arranged to execute such a computer program product.

[0080] The use of the terminal provides flexibility of operation because it facilitates the modification of the operating conditions and restrictions of each electrical equipment.

[0081] The different aspects defined above which are not incompatible can be combined. Brief description of the figures

[0082] The invention will be better understood with the aid of the detailed description which is set out below with reference to the attached drawings.

[0083] [Fig.l] is a schematic view of an installation comprising electrical equipment, an electric meter and a communication system.

[0084] [Fig.2] is a diagram showing the steps of a method of configuring the communication system. Description with reference to the figures

[0085] In the detailed description which follows of the figures defined above, the same elements or the elements fulfilling identical functions may retain the same references so as to simplify the understanding of the invention.

[0086] As illustrated in [Fig.l], a communication system 1 is suitable for several electrical devices 3 connected to an electrical network.

[0087] The communication system 1 comprises an input 5 configured to receive an input signal 7 emitted by a communicating output 9 of an electric meter 11 of an installation 13 comprising the electrical equipment 3.

[0088] The communication system 1 comprises, for each electrical equipment 3, an output 15 configured to emit at least one corresponding output signal 17 to the electrical equipment 3.

[0089] Each output signal 17 comprises at least one piece of control information capable of being interpreted by the corresponding electrical equipment 3.

[0090] The communication system 1 comprises a processing unit 19 configured to determine whether the input signal 7 is according to a first communication protocol H or according to a second communication protocol S.

[0091] The processing unit 19 is configured to recognize, in the input signal 7, at least one operating indication relating to the electrical equipment 3 and / or the electrical network.

[0092] The processing unit 19 is also configured to develop the output signals 17 as a function of said at least one operating indication.

[0093] It appears that the communication system 1 can receive an input signal 7 according to two different communication protocols. The communication system 1 recognizes the communication protocol used and retrieves the information it contains: the operating indications.

[0094] The communication system 1 then produces one or more output signals 17, each output signal 17 being intended for an electrical device 3 with at least one piece of control information interpretable by the electrical device 3.

[0095] The communication system 1 is thus an element of an installation 13 arranged between the electric meter 11 and the electrical equipment 3 for the purpose of communicating interpretable information to each electrical equipment 3, regardless of whether the input signal 7 coming from the electric meter 11 is according to the first communication protocol H or according to the second communication protocol S.

[0096] Thus, depending on the scenario, not only does the communication system 1 read the input signal 7 and develop one or more pieces of control information on this basis, but it also emits each output signal 17 in a particular format adapted to a particular piece of electrical equipment 3.

[0097] The communication system 1 comprises a visual indicator 21 configured to display whether the input signal 7 is according to the first communication protocol H or according to the second communication protocol S.

[0098] The visual indicator 21 is in the form of two indicator lights 23 arranged to light up in order to inform a user of the communication system 1.

[0099] The communication system 1 comprises a housing 25 adapted to receive the processing unit 19, the input 5 and the outputs 15.

[0100] Input 5 and outputs 15 are sockets suitable for a wired connection. Alternatively, input 5 may be an input for receiving a wireless signal, for example from a dedicated adapter 27 mounted on the communicating output 9 of the electricity meter IL.

[0101] According to another alternative, at least one output 15 can be a transmitter of a wireless signal to an electrical device 3 adapted to receive this type of signal.

[0102] In this text, "wireless" means remote communication by modulated electromagnetic waves. For example, it may be Bluetooth, low energy Bluetooth or BLE, wifi, mobile networks, satellites, etc.

[0103] The processing unit 19 is configured to determine whether the input signal 7 is according to the first communication protocol H or according to the second communication protocol S by measuring a baud rate of the input signal 7.

[0104] The input signal 7 is in the form of data frames. In particular, the transmission of frames takes place every two seconds. The first communication protocol H, also called historical mode, has a baud rate of 1200. The second communication protocol S, also called standard mode, has a baud rate of 9600.

[0105] By being inserted between the electric meter 11 and the electrical equipment 3, the present communication system 1 can be used with an input signal 7 indifferently in historical mode or in standard mode.

[0106] Thus, if no adjustment is made at the level of the mode of the electric meter 11, this no longer poses an operating problem: the communication system 1 integrates any type of input signal 7 and translates it if necessary to each electrical equipment 3 according to its specificities.

[0107] Each output 15 may be of the unidirectional type or of the bidirectional type, a return signal 29 coming from a corresponding electrical equipment 3 being capable of being received by the at least one output 15 of the bidirectional type.

[0108] Indeed, depending on the electrical equipment 3, it may be useful to receive a return signal 29 which is taken into account by the processing unit 19.

[0109] For example, for an electrical device 3 of the electric car charger type, it may be useful for the return signal 29 to contain information on the quantity of energy remaining to be charged, a cut-off time at which the charge must end, etc. The processing unit 19 can then determine the output signal 17 so as to respect the constraints of the charger and also the constraints known by the input signal 7.

[0110] Each output 15 is configured to emit a corresponding output signal 17 to a corresponding electrical device 3.

[0111] The plurality of outputs 15 comprises at least one output 15 configured to emit an output signal 17 according to the first communication protocol H, at least one output 15 configured to emit an output signal 17 according to the second communication protocol S and / or at least one output 15 configured to emit the output signal 17 by switching a dry contact C of said output 15.

[0112] Each output 15 emits an output signal 17 according to a unique format. This may be the first communication protocol H, the second communication protocol S or a switching of a dry contact C.

[0113] The at least one output 15 configured to transmit according to the first communication protocol H is of the unidirectional type and the at least one output 15 configured to transmit according to the second communication protocol S is of the bidirectional type.

[0114] Indeed, the second communication protocol S being more recent, it is adapted to electrical equipment 3 itself recent which is capable of emitting return signals S.

[0115] However, alternatively, it is possible to provide only unidirectional or bidirectional type outputs 15 for both the first communication protocol H and the second communication protocol S.

[0116] Furthermore, the outputs 15 by switching dry contact C are of the relay closing and opening type to start or stop certain electrical equipment 3. These are outputs of simple construction.

[0117] Furthermore, it is possible to provide at least one output 15 adapted to emit an output signal 17 according to a third communication protocol different from the first communication protocol H and the second communication protocol S.

[0118] For example, the third communication protocol can be the OCCP language which is also suitable for electric car chargers.

[0119] The communication system 1 may also comprise one or more connectors to be fixed to an output 15 or a bus to connect the communication system 1 to a particular electrical equipment 3.

[0120] Here, the communication system 1 comprises a first data transfer bus 31 including at least one output 15 configured to emit a signal of output 17 according to the first communication protocol H and a second data transfer bus 33 including at least one output 15 configured to emit an output signal 17 according to the second communication protocol S.

[0121] The first data transfer bus 31 is of the unidirectional type. This type of bus is suitable for electrical equipment 3 consuming electricity to operate, such as an electric heater.

[0122] In this case, the unidirectional bus is suitable because there is no need for feedback to the communication system.

[0123] An output 15 according to the second communication protocol S is for example included in a bidirectional data transfer bus. It may be an RJ45 connection or equivalent suitable for bidirectional data transfer.

[0124] Each piece of control information corresponds to at least one operating indication and / or to at least one start-up instruction, one stop instruction, one power reduction instruction in a determined proportion.

[0125] It appears that the processing unit 19 can provide several different responses following its programming. It is thus possible to prioritize certain electrical equipment such as heating or air conditioning and request to lower the power of others such as the electric car charger.

[0126] The processing unit 19 is a programmable automaton, the processing unit 19 comprising in memory a program 35 for developing the at least one output signal 17 as a function of the input signal 7.

[0127] The processing unit 19 also comprises in memory, to carry out the corresponding functions mentioned above, a recognition module 36 of the input signal 7 to determine the communication protocol used and a translation module 38 used to interpret the input signal 7 and express the output signals 17 according to the correct format.

[0128] This defines the control information(s) to be transmitted to electrical equipment according to the operating indication(s) received.

[0129] The programmable controller is a microprocessor with an initial program installed in the factory.

[0130] The communication system 19 further comprises a data exchange module 37 designed to receive instructions for modifying the program 39 and / or to transmit data 41 from the memory of the programmable controller.

[0131] This involves adapting to the addition or removal of electrical equipment 3 by configuring an output 15 not used until then. Furthermore, if the operating indications emitted by the electric meter 11 change over time, this makes it possible to adapt the communication system 1.

[0132] The data exchange module 37 may be wired. Alternatively or in addition, the data exchange module 37 may be wireless. It may be provided to use only one wireless communication module for all the wireless data exchanges of the communication system 1. The same wireless module may then be able to communicate with the electricity meter 11, at least part of the electrical equipment 3 and / or any other suitable external device.

[0133] As illustrated in [Fig.2], a method for configuring a communication system 1 comprises a step E1 consisting of having an installation 13 comprising at least one electrical equipment 3, an electric meter 11 and the communication system 3.

[0134] A step E2 consists of establishing a communication between a terminal 43 and the data exchange module 37 of the communication system 1.

[0135] The configuration method then comprises a step E3 consisting of modifying the program 35 dedicated to the development of at least one output signal 17 with the terminal 43.

[0136] The program 35 defines each control information intended for a determined electrical equipment 3 as a function of at least one operating indication.

[0137] It is thus possible to modify the way in which the electrical equipment 3 is controlled without having to modify the installation. The communication system 3 does not have to be replaced: it is sufficient to update the program.

[0138] The terminal 43 is capable of connecting to the data exchange module 37 via a wired or wireless connection. Preferably, the terminal 43 is a tablet, a computer, a telephone, or any other electronic device having a user interface.

[0139] Program 35 defines which electrical equipment 3 has priority in its operation. For example, a heater can be defined as a priority because it must not be turned off even if the installation 13 needs electrical current for other applications.

[0140] Program 35 can define that on the contrary the water heater, even when it is in operation, can be cut off by opening the corresponding dry contact C if a more urgent need for energy is necessary.

[0141] Program 35 can define that the electric car charger operates at full power during off-peak hours although a rise in current approaching the maximum current of the subscription may call for the sending of reduced power control information.

[0142] All of these rules that emerge from the programming have multiple benefits: the user experience is improved because he does not see the equipment electrical equipment 3 that it considers to be a priority to be limited in their operation.

[0143] The maximum intensity of the installation subscribed to by the user can be reduced. Indeed, program 35 can limit the concomitant use of numerous energy-hungry electrical equipment 3. Also, savings can be made by the choices of operation of certain electrical equipment 3 during off-peak hours.

[0144] The modification of the program 35 consists of entering on an interface of the terminal 43, for each electrical equipment of the installation 13, a condition of operation at full power, a condition of operation at reduced power in a determined proportion and / or a shutdown condition, said conditions being configured to apply to the operating indications of the input signal 7.

[0145] The interface of the terminal 43 makes it possible to specify for each electrical equipment 3 the operating restriction modalities. Preferably, it is a web interface.

[0146] The use of the terminal 43 provides flexibility of operation because it facilitates the modification of the operating conditions and restrictions of each electrical equipment 3.

[0147] As goes without saying, the invention is not limited to the single embodiment described above as an example; on the contrary, it encompasses all the variant embodiments.
