The output connector 38 is configured to deliver each frame according to the TIC protocol in historical mode, coming from the transformation device 30, and comprises a first output terminal 62, also denoted I1', and a second output terminal 64, also denoted I2'. An energy manager for a hot water tank or an energy manager for an electric heater is then adapted to be electrically connected to the first and second output terminals 62, 64.

The power supply device 40 is configured to electrically supply the transformation device 30, from the electrical power received at the first and third input terminals 56, 60 from the terminals I1 and A of the TIC interface. 24.

In the example of FIG. 2, the power supply device 40 comprises a protection module 66 connected to the first and third input terminals 56, 60, a first conversion module 68 connected to the output of the protection module 66 and a second conversion module 70 connected to the output of the first conversion module 68. The protection module 66 is configured to filter any overvoltages present in the electrical power supply received from the ICT interface 24, and is then able to protect the conversion modules 68, 70 against these possible overvoltages. The first conversion module 68 is configured to convert an AC input voltage, received at the first and third input terminals 56, 60 (the power supply delivered by the TIC interface 24 being an AC power supply), into an AC power supply. DC output voltage, delivered to the second conversion module 70. In other words, the first conversion module 68 is a voltage rectifier. The second conversion module 70 is configured to convert a first DC voltage U1, received as input from the first conversion module 68, into a second DC voltage U2, intended to be delivered to the processing module 50, as well as part to the post-processing module 54. In other words, the second conversion module 70 is a DC-DC converter. The first DC voltage U1 is also intended to be delivered in part to the post-processing module 54. The first DC voltage U1 coming from the first conversion module 68 is for example substantially between 3.5 volts and 17 volts. The second DC voltage U2 is for example substantially equal to 3.3 volts. The first and second conversion modules 68, 70 are for example referenced with respect to an electrical ground 72, said electrical ground 72 also being for example electrically connected to the first output terminal 62 of the output connector 38.

The processing module 50 is configured to detect the protocol from among the TIC protocol in standard mode and the TIC protocol in historical mode of each frame received from the TIC interface 24, and to then adapt, according to the detected protocol, the transformation of each frame received into a respective frame according to the TIC protocol in historical mode.

The processing module 50 is for example configured to copy at its output a frame received at its input when the detected protocol is the TIC protocol in historical mode. In addition, when the detected protocol is the TIC protocol in standard mode, the processing module 50 is further configured to convert each frame received conforming to the TIC protocol in standard mode into a respective frame conforming to the TIC protocol in historical mode.

As an optional addition, the TIC protocol in standard mode comprises at least two tariff indices and the TIC protocol in historical mode comprises only a low tariff index and a high tariff index. According to this optional complement, for the conversion of each frame according to the TIC protocol in standard mode into a respective frame according to the TIC protocol in historical mode, the processing module 50 is further configured to encode the lowest pricing index of the TIC protocol in standard mode into the low pricing index of the TIC protocol in historical mode, and respectively to encode the other pricing index(es) of the TIC protocol in standard mode into the high pricing index of the TIC protocol in historical mode.

The processing module 50 is configured to detect the protocol of each frame received from the TIC interface 24 from among the TIC protocol in historical mode and the TIC protocol in standard mode, in particular according to a rate of each frame received. The TIC protocol in historical mode corresponds for example to a bit rate substantially equal to 1200 bauds, while the TIC protocol in standard mode corresponds to a bit rate substantially equal to 9600 bauds. In other words, the processing module 50 is, according to this example, configured to detect that the frame received is a frame according to the TIC protocol in standard mode if its bit rate is close to 9600 bauds, and as a corollary to detect that the frame received is according to the TIC protocol in historical mode if its speed is close to 1200 bauds.

This detection is for example carried out by initially assuming that the frame received is a frame according to the TIC protocol in standard mode with a bit rate substantially equal to 9600 bauds, then by seeking to find frame delimiters and to read the content of expected fields on base this initial configuration at 9600 baud; and by switching, if necessary, to a 1200 baud configuration if the frame delimiters are not found and/or if the content of the expected fields is not readable. In other words, according to this example, the processing module 50 begins by assuming that the frame received is a frame according to the TIC protocol in standard mode to perform the processing of the frame received, and then considers, if necessary, that the frame received is finally a frame according to the TIC protocol in historical mode, if it fails to process the frame received on the basis of the initial assumption that it was according to the TIC protocol in standard mode.

Those skilled in the art will of course understand that as a variant this detection can be carried out on the basis of the alternative initial hypothesis that the frame received is a frame according to the TIC protocol in historical mode. According to this variant, this detection is then carried out by initially assuming that the frame received is a frame according to the TIC protocol in historical mode with a rate substantially equal to 1200 bauds, then by seeking to find frame delimiters and to read the content of expected fields based on this initial configuration at 1200 baud; and by switching, if necessary, to a configuration at 9600 bauds if the frame delimiters are not found and/or if the content of the expected fields is not readable.

As a further variant, this detection is carried out by comparison with a predefined threshold, for example equal to an intermediate value between 1200 bauds and 9600 bauds, such as a value substantially equal to 5400 bauds.

For the conversion of each frame according to the TIC protocol in standard mode into a respective frame according to the TIC protocol in historical mode, the processing module 50 is for example configured for:

- copy an ADSC field of the TIC frame in standard mode into an ADCO field of the TIC frame in historical mode, corresponding to a counter address,

- convert an NGTF field of the TIC frame in standard mode into an OPTARIF field of the TIC frame in historical mode, corresponding to a chosen tariff option, an example of this conversion being described in more detail below;

- acquire the value of a PREF field of the TIC frame in standard mode and divide it by 200 to copy it into an ISOUSC field of the TIC frame in historical mode, corresponding to a subscribed intensity;

- copy an EASF01 field from the TIC frame in standard mode into a BASE or HCHC field of the historical TIC frame, corresponding to an option index 1;

- copy, when present, an EASF02 field of the TIC frame in standard mode into an HCHP field of the TIC frame in historical mode, corresponding to an option index 2;

- convert an LTARF field of the TIC frame in standard mode into a PTEC field of the TIC frame in historical mode, corresponding to a current tariff period, an example of this conversion being described in more detail below;

- copy an IRMS1 field of the TIC frame in standard mode into an IINST1 field of the TIC frame in historical mode, corresponding to an instantaneous intensity of a first phase numbered 1;

- in the case of three-phase current, copy an IRMS2 field from the TIC frame in standard mode into an IINST2 field from the TIC frame in historical mode, corresponding to an instantaneous intensity of a second phase numbered 2;

- in the case of three-phase current, copy an IRMS3 field into an IINST3 field of the TIC frame in historical mode, corresponding to an instantaneous intensity of a third phase numbered 3;

- copy a predefined intensity value, such as a value equal to 60 amperes, into fields referenced IMAX1, respectively IMAX2, respectively still IMAX3, of the TIC frame in historical mode, corresponding to a maximum intensity of the first numbered phase 1, and in the case of three-phase current respectively at a maximum intensity of the second phase numbered 2, and respectively again at a maximum intensity of the third phase numbered 3;

- in case of single-phase current, calculate an IR ratio of a PREF field divided by 200; and if the value of an IINST field (corresponding to an IRMS field, such as the IRMS1 field of the TIC frame in standard mode) is greater than this IR ratio, copying this IR ratio into an ADPS field of the TIC frame in standard mode history, corresponding to a warning of exceeding the subscribed power;

- in case of three-phase current, copy an SMAXSN-1 field of the TIC frame in standard mode into a PMAX field of the TIC frame in historical mode, corresponding to a maximum three-phase power reached;

- Copy a SINSTS field from the TIC frame in standard mode into a PAPP field from the TIC frame in historical mode, corresponding to an apparent power withdrawn;

- copy a predefined value, such as the alphanumeric character "A", into an HHPHC field of the TIC frame in historical mode, corresponding to a peak hour HP/off-peak hour HC schedule;

- copy a predefined value, such as the alphanumeric character string "000000", into a MOTDETAT field of the TIC frame in history mode, corresponding to a status mode; and

- in the case of three-phase current, convert an IRMS1/2/3 field of the TIC frame in standard mode into a PPOT field of the TIC frame in historical mode, corresponding to the presence of a potential.

The PPOT field of the TIC frame in historical mode consists of the 2 characters obtained by the ASCII coding of each of the two digits represented by the two quartets of the byte defined below, making it possible to check the validity of the potentials on each of the phases: bit 0: always at 0; bit 1: phase 1 potential < VRP; bit 2: phase 2 potential < VRP; bit 3: phase 3 potential < VRP; bits 4, 5, 6 and 7: Reserved for ENEDIS (always at 0).

The conversion of the IRMS1/2/3 field(s) of the TIC frame in standard mode into the PPOT field of the TIC frame in historic mode is for example performed by setting bit 1 of the PPOT field to 1 in the event of a power failure. on IRMS1, by setting bit 2 of the PPOT field to 1 in the event of no current on IRMS2, and respectively by setting bit 3 of the PPOT field to 1 in the event of no current on IRMS3, then converting to the format hexadecimal the resulting binary number. According to this example, the PPOT field of the TIC frame in historical mode is then set to "00" if all the IRMS1/2/3 fields are non-zero; to "02" if phase 1 absent; to "04" if phase 2 absent; to "08" if phase 3 absent; to "06" if phases 1 and 2 absent; to "0C" if phases 2 and 3 absent; to "0A" if phases 1 and 3 missing; and to "0E" if phases 1, 2 and 3 are absent.

The aforementioned conversion of each frame according to the TIC protocol in standard mode into a respective frame according to the TIC protocol in historical mode is then summarized in table 1 below.

For the conversion of the NGTF field of the TIC frame in standard mode into the OPTARIF field of the TIC frame in historical mode corresponding to the tariff option chosen, the processing module 50 is for example configured to start by searching for a "BASE" pattern inside the NGTF field, and in the event of positive detection, that is to say in the event of detection of said pattern inside said field, meaning then that the NGTF field corresponds to a BASE offer, position the value of the OPTARIF field of the TIC frame in historical mode to the value "BASE", to indicate that the tariff option chosen is a basic offer. If the search for the "BASE" pattern is not conclusive, the processing module 50 is configured to then search for the "H" pattern inside the NGTF field of the TIC frame in standard mode then, in the event of a positive detection , then search for the "SUPER" or "HSC" pattern, and in the event of a positive detection, meaning that the NGTF field corresponds to an HSC offer (for Super Off-peak Hours), then position the value "HC.." in the field OPTARIF of the TIC frame in historical mode, the size of the OPTARIF field being four characters. If the search for the "SUPER" or "HSC" pattern within the NGTF field of the TIC frame in standard mode is unsuccessful, the processing module 50 is configured to then search for the "FULL" or "HOLLOW" or " HP” or even “HC”, and in the event of a positive detection, meaning that the NGTF field corresponds to an HP/HC offer (for Peak Hours / Off-Peak Hours), position the value “HC..” in the OPTARIF field of the TIC frame in historical mode.

On the other hand, if the search for the reason "PLEIN", "CREUS", "HP", or even "HC" is unsuccessful, then the tariff offer is unknown (i.e. other than the BASE, HSC offers and HP/HC cited above). In this case, the processing module 50 is configured to then position the value "HC.." in the OPTARIF field of the TIC frame in historical mode if the LTARF field of the TIC frame in standard mode corresponds to an index HP, HC , or HSC, or set the value "BASE" in the OPTARIF field if said LTARF field corresponds to a BASE or other index. The determination of the index corresponding to the LTARF field of the TIC frame in standard mode is described below.

If the previous search for the "H" pattern inside the NGTF field of the TIC frame in standard mode is unsuccessful, the processing module 50 is configured to search in this case for the "DOUBLE" pattern inside the NGTF field. of the TIC frame in standard mode, and in the event of positive detection, position the value "HC.." in the OPTARIF field of the TIC frame in historical mode, and otherwise position, according to the LTARF field of the TIC frame in mode standard and in the manner previously indicated following the index corresponding to this field, the value "HC.." or "BASE" in the said OPTARIF field, the offer being unknown in the latter case.

To determine the index corresponding to said LTARF field, the processing module 50 is for example configured to begin by searching for the "BASE" pattern inside the LTARF field, and in the event of a positive detection, then determining that the index corresponding to said LTARF field is the BASE index. If, on the other hand, the search for the "BASE" pattern is unsuccessful, then the processing module 50 is configured to then search for the "H" pattern inside the LTARF field, then in the event of a positive detection, search for the "SUPER" pattern. or "HSC", and in the event of a positive detection of one of the latter fields, determining that the index corresponding to said LTARF field is the HSC index.

If, on the other hand, the search for one of these latter patterns is unsuccessful, then the processing module 50 is configured to then search for the "CREUS" or "HC" pattern inside the LTARF field, and in the event of positive detection , determining that the index corresponding to said LTARF field is the HC index. On the other hand, if the search for the "CREUS" or "HC" pattern is unsuccessful, the processing module 50 is then configured to search for the "FULL" or "HP" pattern inside the LTARF field, and in the event of detection positive of one of said patterns, determining that the index corresponding to said LTARF field is the HP index.

On the other hand, if the search for the pattern "PLEIN" or "HP", or the previous search for the pattern "H", is unsuccessful, then the index is unknown, and it then corresponds to the label 'Other' in table 2 below.

The conversion of the LTARF field of the TIC frame in standard mode into the PTEC field of the TIC frame in historic mode corresponding to the current tariff period is then performed by the processing module 50 according to Table 2 below, specifying the value set in the PTEC field among the values "TH..", "HP.." and "HC..", the size of the PTEC field being four characters, this depending on the offer corresponding to the NGTF field of the TIC frame in standard mode and the index corresponding to the LTARF field of the TIC frame in standard mode, previously determined, as explained previously.

In the example of FIG. 2, the processing module 50 then comprises a stage 80 for receiving the frame in the form of a binary signal from the pre-processing module 52, a first stage 82 for temporarily storing said frame received, before its conversion, a stage 84 for converting the TIC frame received into a respective frame according to the TIC protocol in historical mode, a second stage 86 for storing said converted frame, before its transmission, and a stage 88 for transmitting the converted frame, for example to the post-processing module 54.

In the example of Figure 2, the processing module 50 comprises an information processing unit 90 formed for example of a memory 92 and a processor 94 associated with the memory 92.

In the example of FIG. 2, the reception stage 80, the first storage stage 82, the conversion stage 84, the second storage stage 86 and the transmission stage 88 are each implemented in the form of software, or a software brick, executable by the processor 94. The memory 92 of the processing module 50 is then capable of storing software for receiving the frame from the preprocessing module 52, a first software for storing the frame received, software for converting the frame received into a respective frame according to the TIC protocol in historical mode, second software for storing the converted frame, and software for transmitting the converted frame, for example to the post-processing module. processing 54. The processor 94 is then capable of executing each of the software programs among the reception software, the first storage software, the conversion software, the second storage software, and the transmission software.

In a variant not shown, the reception stage 80, the first storage stage 82, the conversion stage 84, the second storage stage 86, and the transmission stage 88, are each made in the form of a component programmable logic, such as an FPGA ( Field Programmable Gate Array ), or else in the form of a dedicated integrated circuit, such as an ASIC ( Application Specific Integrated Circuit ).

When the processing module 50 is produced in the form of one or more software, that is to say in the form of a computer program, it is also able to be recorded on a medium, not shown, readable by computer. The computer-readable medium is, for example, a medium capable of storing electronic instructions and of being coupled to a bus of a computer system. By way of example, the readable medium is an optical disc, a magneto-optical disc, a ROM memory, a RAM memory, any type of non-volatile memory (for example EPROM, EEPROM, FLASH, NVRAM), a magnetic card or another optical card. On the readable medium is then stored a computer program comprising software instructions.

The preprocessing module 52 is configured to digitize each frame, received in the form of an analog signal from the TIC interface 24, into a binary signal, that is to say into a binary frame, such as a UART frame (from the English Universal Asynchronous Receiver Transmitter ), delivered to the processing module 50.

The pre-processing module 52 is for example configured to, during digitization of the analog frame into the binary frame, such as the UART frame, position a bit with a value equal to 1 in the binary frame, in the absence of a modulation in the analog frame, and respectively to position a bit with a value equal to 0 in the binary frame in the event of the presence of a modulation in the analog frame. The modulation is for example a modulation with a frequency substantially equal to 50 kHz.

The pre-processing module 52 comprises for example one or more optocouplers to further provide, in addition to the digitization described above, electrical insulation between the input connector 36 and the processing module 50.

The post-processing module 54 is configured to modulate with a carrier the binary signal, or even the binary frame, coming from the processing module 50 into an analog signal, or even an analog frame. The carrier frequency is preferably substantially equal to 50 kHz.

In the example of FIG. 2, the post-processing module 54 comprises a modulation stage 96 configured to remodulate the binary signal coming from the processing module 50, such as the UART frame, with the carrier, such as the carrier of frequency substantially equal to 50 kHz, to reconstruct the analog signal, or frame, the modulation stage being connected to the output of the processing module 50. The modulation stage 96 is for example electrically powered with the second DC voltage U2 , from the second conversion module 70.

The post-processing module 54 then for example then comprises a conversion stage 98, connected to the output of the modulation stage 96, the conversion stage 98 being configured to enhance the voltage of the analog signal coming from the modulation stage 96, from a peak voltage substantially equal to the second voltage U2 to a peak voltage substantially equal to the first voltage U1. The conversion stage 98 is for example electrically powered with the first DC voltage U1, coming from the first conversion module 68.

In the example of FIG. 2, the post-processing module 54 also comprises a protection stage 100 connected between the conversion stage 98 and the output connector 38. The protection stage 100 is configured to protect the modulation stage 96 and conversion stage 98, as well as processing module 50 and pre-processing module 52, against possible overvoltages present in output connector 38. Protection stage 100 is for example configured to offer protection against overvoltages up to 230 volts, and then makes it possible to limit the risks of deterioration of the modulation 96 and conversion 98 stages, as well as the processing 50 and preprocessing 52 modules, in the event of a bad connection of output connector 38.

The operation of the generation system 20, and more generally of the transmission installation 10, will now be explained with reference to FIG. 3 representing a flowchart of the method according to the invention for generating at least one data frame, the method being implemented by the generation system 20.

During an initial step 200, the generation system 20 receives, via its transformation device 30, for example via its pre-processing module 52, then the reception stage 80 of the processing module 50, a respective data frame from the ICT interface 24. During this reception step 200, the generation system 20 preferably stores each frame received via the first storage stage 82 of the processing module 50.

The generation system 20 then transforms, during the next step 210 and via its transformation device 30, each frame received from the TIC interface 24 into a respective frame according to the TIC protocol in historical mode.

The transformation step 210 then includes for example a sub-step 215 of detecting the type of TIC protocol of each frame received, from among the TIC protocol in standard mode and the TIC protocol in historical mode. This detection sub-step 215 is for example performed by the processing module 50.

During the detection sub-step 215, if the detected protocol is the TIC protocol in standard mode, the transformation device 30 then proceeds to a sub-step 220 of converting each frame according to the TIC protocol in standard mode into a frame. respective according to the TIC protocol in historical mode. This conversion sub-step 220 is for example performed by the processing module 50, in particular by its conversion stage 84.

At the end of this conversion sub-step 220, the generation system 20 moves on to the next step 230 during which each frame according to the TIC protocol in historical mode is transmitted to the output connector 38, for example via the module 50, and in particular via its transmission stage 88, then preferably via the post-processing module 54, in order to then be delivered to a respective electrical equipment connected to said output connector 38.

During the detection sub-step 215, if the detected protocol is the TIC protocol in historical mode, then the transformation device 30 passes to a following sub-step 225 during which the transformation device 30, in particular its processing 50, copies at its output the frame according to the TIC protocol in historical mode received at its input.

At the end of the copying sub-step 225, the generation system 20 also passes to the transmission step 230 during which each frame according to the TIC protocol in historical mode is transmitted, via the output connector 38, to each electrical equipment connected at the output of the generation system 20.

At the end of the transmission step 230, the generating system 20 returns to the reception step 200, in order to receive one or more new data frames from the TIC interface 24.

Thus, the generation system 20 according to the invention makes it possible to generate one or more data frames according to the TIC protocol in historical mode, in particular when the TIC interface 24 is configured in standard mode and then transmits data frames only according to the TIC protocol in standard mode. Indeed, the transformation device 30 is able to transform each frame received from the ICT interface 24 into a respective frame according to the ICT protocol in historical mode.

This then makes it possible to offer continuity of operation for the electrical equipment or equipment operating only with the ICT protocol in historical mode, such as energy managers for hot water tanks, or even for electric heating.

Furthermore, when the electronic transmission installation 10 comprises both an ERL14 communication system connected to the electricity meter 12 and adapted to transmit electricity consumption data from frames received from the TIC interface 24 according to the TIC protocol in mode standard, and the generation system 20 according to the invention, it then makes it possible to have both frames according to the TIC protocol in standard mode and frames according to the TIC protocol in historical mode. Indeed, the frames according to the TIC protocol in standard mode then come from the TIC 24 interface which is programmed in standard mode to allow the operation of the ERL14 communication system, and the frames according to the TIC protocol in historical mode come from the generation system 20 according to the invention.

According to an optional additional aspect of the invention, the generation system 20 offers optimized management of the electrical energy consumed from the TIC interface 24, the electrical power delivered by the TIC interface 24 being in fact limited, by example at 130 milliwatts, or mW. The generation system 20 is in particular configured not to disturb the operation of the communication system ERL14 when said communication system 14 needs to use all of the energy supplied by the ICT interface 24, and the generation system 20 is then configured to go into a standby mode in this case, in order to dedicate all of the energy available from the ICT interface 24 to the communication system ERL14.

The generation system 20 is then, for example, configured to detect a power supply voltage received at its input connector 36 which is lower than a first predefined threshold, that is to say to detect a low power supply, and for the if necessary, switch to standby mode, so as not to consume too much of the electrical energy delivered by the TIC interface 24, and leave all or almost all of this energy delivered by the TIC interface 24 for the operation of the ERL14 communication system.

To this end, the processing module 50 is for example configured to acquire, at its start-up, a measurement of a voltage representative of the voltage delivered by the TIC interface 24, and if the voltage acquired is lower than the first threshold, to switch to standby mode for a predefined timeout period, such as for example a period substantially equal to ten minutes.

The voltage representative of the voltage delivered by the TIC interface 24 is for example the first DC voltage U1. As a variant, said representative voltage is the voltage delivered by the TIC interface 24, that is to say the alternating voltage received directly between the first and third input terminals 56, 60 of the input connector 36, of the from terminals I1 and A of the TIC 24 interface.

This switch to standby mode at start-up in the event of the supply voltage of the TIC 24 interface being too low then makes it possible to give priority to the ERL14 communication system to connect to the TIC 24 interface, and carry out its initialization, then the start of the transmission of electricity consumption data from the electricity meter 12, via the TIC interface 24. The value of the first threshold is for example substantially equal to 6 V when the representative voltage is the first voltage U1.

At the end of said timeout period, the processing module 50 is configured to acquire a new measurement of the voltage representative of the supply voltage delivered by the TIC interface 24, and if said representative voltage is still lower than the first threshold, to once again switch to standby mode for said timeout period, that is to say to remain in standby mode for said timeout period. Otherwise, that is to say if the representative voltage is this time greater than the first threshold, then the processing module 50 is configured to switch to a normal operating mode, that is to say in the mode where the processing module 50 transforms each frame received from the TIC interface 24 into a respective frame according to the TIC protocol in historical mode, as described above. When the voltage representative of the supply voltage of the TIC interface 24, measured a second time at the expiration of the first occurrence of the timeout period, is again lower than the first threshold, the processing module 50 is configured to, at the expiration of a second occurrence of the time delay duration, acquire a new measurement of said representative voltage, and if said measured representative voltage is then greater than the first threshold, to switch to normal mode. If said measured representative voltage is for the third consecutive time lower than the first threshold, the processing module 50 is then configured to nevertheless operate in normal mode, but this for a reduced duration, such as for example a duration substantially equal to five minutes. This then allows the generation system 20 to transmit one or more TIC frames according to the historical mode, intended for the electrical equipment or equipment, such as energy managers, which are connected to it. This makes it possible, for example, to provide information to an energy manager, such as a switch to off-peak time which would then make it possible to trigger an ignition of the hot water tank, or even an ignition of the electric heating.

As a further optional addition, when the processing module 50 has switched to normal mode, the processing module 50 is also configured to regularly acquire a measurement of the voltage representative of the supply voltage supplied by the ICT interface 24, and if said representative voltage is less than a predefined complementary threshold, returning to standby mode for a predefined standby duration, such as said reduced duration, of value for example substantially equal to five minutes. The value of the complementary threshold is for example substantially equal to 4.3 V when the representative voltage is the first voltage U1. This then makes it possible to regularly check the supply voltage supplied by the TIC 24 interface and to switch back to standby mode when necessary, in order to give priority to the ERL14 communication system if necessary. At the end of this standby time, the processing module 50 is configured to acquire a new measurement of the voltage representative of the supply voltage of the TIC interface 24, and in a similar manner, if said representative voltage is greater than the complementary threshold, returning to normal operating mode, and conversely if said representative voltage is still lower than the complementary threshold, to remain in standby mode. Here again, if the processing module 50 remains in standby mode for a predefined maximum duration, typically corresponding to six occurrences of said standby duration, such as for example a duration substantially equal to thirty minutes, the processing module 50 is then configured to switch back to normal operating mode on the expiry of this maximum duration, and this for a duration equal to the reduced duration, in order to generate one or more frames according to the TIC protocol in historical mode, before then switching back to standby mode if necessary, that is to say if the representative voltage is again lower than the complementary threshold.

As a further optional addition, the power supply device 40 is also configured to measure the voltage representative of the voltage supplied by the TIC interface 24 and to compare it with a second predefined threshold, of value lower than the first threshold, as well as the case applicable to the additional threshold. The value of the second threshold is for example substantially equal to 3.8 V when the representative voltage is the first voltage U1. The supply device 40 is then, if said representative voltage is lower than the second threshold, configured to inhibit the operation of the generation system 20, the generation system 20 then being deactivated, that is to say to no longer supply the transformation device 30, in order to no longer consume energy on the ICT interface 24. According to this optional addition, the power supply device 40 is preferably furthermore configured to reactivate automatically when the voltage representative of the supply voltage supplied by the TIC interface 24 is again greater than a predefined restart threshold. The value of the restart threshold is preferably equal to the sum of the value of the second of the threshold and a voltage delta, in order to have hysteresis operation. The value of the restart threshold is then for example substantially equal to 4.2 V when the representative voltage is the first voltage U1. This reactivation of the power supply device 40 then makes it possible to power the transformation device 30 again, and in particular the processing module 50, which is then able to again process the frames received from the ICT interface 24 to generate respective frames according to the TIC protocol in historical mode, or to switch to standby mode if the voltage of the TIC interface 24 is between the second threshold and the first threshold.

Those skilled in the art will then understand that when the generation system 20, and in particular the transformation device 30, again in particular the processing module 50, is in standby mode, the latter is not completely deactivated and is able in particular to regularly acquire a new measurement of the voltage representative of the supply voltage supplied by the TIC interface 24, in order to be able to then determine whether or not it is possible for it to return to normal operating mode. On the other hand, when the generation system 20 is deactivated, following detection of a measurement of said representative voltage lower than the second threshold, it is in a state consuming even less energy than in standby mode, and is not then no longer able to acquire a new measurement of said representative voltage, the only possibility of reactivating the generation system 20 being then that the voltage representative of the supply voltage supplied by the TIC interface 24 is again greater than the threshold restart.

According to this complementary aspect, the generation system 20 then offers optimized management of the electrical energy consumed vis-à-vis the TIC interface 24 in order to offer an operating priority to the communication system ERL14.

It is thus seen that the generation system 20 and the generation method according to the invention make it possible to improve the operation of electrical equipment(s), such as energy managers for water tanks hot and electric heating appliances, requiring to receive one or more frames according to the TIC protocol in historical mode, while the TIC interface 24 of the electric meter 12 is in certain cases configured in standard mode, in particular when an ERL communication system is connected to said TIC interface 24 of the electricity meter 12.
