PROGRAMMABLE ELECTRICAL POWER SOCKET
IN ACCORDANCE WITH TARIFF ORDERS
Electrical energy distributors are constantly striving to improve and diversify electricity distribution services to their customers.

 To offer diversified electricity distribution services, retailers offer, among other things, different consumption methods, according to specific choice criteria, left to the initiative of each customer.

 For this purpose each customer can choose the mode of consumption which seems to him the most appropriate, according to either requirements of use, schedules or calendars of use.

 In addition, distributors, in order to encourage their customers to make such choices, offer advantageous pricing conditions, allowing any customer who has made such a choice to benefit from considerable savings in the amount of consumption charged. This is for example the application of "off-peak" rates which, more advantageous than normal rates, constitute an incentive for such a choice for customers.

 The use of such a choice allows the distributors, and, consequently, the producers of electrical energy to ensure a better average distribution of daily power calls and to better organize the management of production resources. .

<Desc / Clms Page number 2>

 For this purpose the distributors carry out transmission on the electricity distribution network, still designated by sector, tariff orders consisting of pulses coded on a low frequency carrier wave.

 To ensure a wide diversification of the consumption modes that can be used, the distributors are implementing centralized remote control systems with musical frequency still referred to as TCFM. This is particularly the case for ELECTRICITE DE FRANCE for the implementation of Tempo rates, EJP, peak hours / off-peak hours, structured in periods corresponding to different kWh prices. In addition to the pricing role, the TCFM allows for customer service applications, such as the control of electrical charges associated with tariffs or collective uses such as street lighting.

However, with regard to subscribers of the ET (Low Voltage) network, the TCFM makes it possible to control the change of tariff at the electricity meter and, if necessary, an electrical load such as a hot water tank. The TCFM implements the injection on the sector of a signal at a specific assigned carrier frequency (generally a low frequency between 100 Hz and 500 Hz). This signal superimposed on the voltage of the network forms a message consisting of pulses, a start pulse, the first, and successive pulses whose position is identified in the message and interpretable according to a tariff order code. By way of example, ELECTRICITE DE FRANCE uses messages consisting of pulses to

<Desc / Clms Page number 3>

 carrier frequency Fo = 175 Hz, at the position of each pulse being associated a tariff order. The detection of these tariff orders by a device or installation of a consumer customer, who has exercised a corresponding tariff choice, allows the device or the installation to be launched under the consumption conditions defined in accordance with the above-mentioned choice.

 This is, for example, the launching and stopping of a domestic hot water tank circuit at 11pm until 5am, during off-peak hours, from corresponding tariff orders by means of a tariff reception relay. The tariff reception relays are used by the distributors and serve to inform the meter or, if applicable, the electrical load concerned of the consumption mode and the current tariff. This is particularly the case for the double full-time / off-peak tariff for ELECTRICITE DE FRANCE for example. The aforementioned tariff reception relays are subject to a specification by the European standard NF EN 61037 (Centralized remote control electronic receivers for charging and load control). They are also the subject of a company specification published under the reference HN 96 S 65 by ELECTRICITE DE FRANCE. These relays are either autonomous or directly integrated into the electricity meter.

 Such a system and the corresponding service are satisfactory. However, it requires the customer to take out a dual-rate contract with the distributor.

 In addition, to ensure a corresponding mode of consumption, for a single device, it is necessary to

<Desc / Clms Page number 4>

 set up a specific power supply circuit equipped with a relay actuated on detection of the corresponding tariff order.

 In addition, when the customer wishes to submit all of its facilities to a regime of choice of pricing, or consumption mode, the so-called solution "rich solution" is to have an energy manager, which is programmed to intelligently control, via the cabling of the customer's internal installation, the electrical appliances of the latter.

 In the absence of setting up an energy manager, it is of course possible to multiply the relay installations operated on detection of the corresponding tariff order. But it is then necessary to modify the entire wiring of the existing installation.

 Finally, another solution called "solution of the poor" can be considered. This solution, for the customer, consists in equipping one or more electrical appliances with simple commercial time schedulers, scheduling the closing and opening times of the programmed connection relay corresponding to the hours when the energy is the same. less expensive.

 The various solutions mentioned above have drawbacks in that the work to change the cabling of the customer's installation or installation of a power manager often involves prohibitive costs, on the one hand, while the simple installation time schedulers, of course, does not allow the customer to benefit fully from the

<Desc / Clms Page number 5>

 advantages granted by distributors when choosing one or more specific consumption modes, on the other hand.

 The present invention aims to overcome the disadvantages of the aforementioned prior art solutions, by implementing a programmable power supply according to tariff orders.

 In particular, in view of such an implementation, the present invention also aims to provide a programmable power supply according to tariff orders, comprising both a programmable setting function and a detection function tariff orders, to ensure the programmed supply of specific electrical devices, in the absence of any modification of the wiring of an existing customer installation.

 The programmable power supply according to tariff orders, object of the present invention, is remarkable in that it comprises a plug plug in a power outlet, a socket, connected to this plug-in plug by the intermediate of a controlled relay and intended to receive an electric charge of use and a control chain of this controlled relay. This control chain comprises at least one module for detecting tariff orders issued by the sector, this detection module connected to the plug-in plug delivering a detected tariff order control signal, and a logical processing module of the control signal. of a tariff order detected comprising a module for selecting a tariff applicable by a user. This module of

<Desc / Clms Page number 6>

 selection allows to program a predetermined tariff order code selected from a plurality of specific tariff orders. This logic processing module further comprises a module for comparing the predetermined tariff order code and the detected tariff order control signal. The logic processing module outputs, upon coincidence of the predetermined tariff order code and the detected tariff order control signal, a controlled relay command signal enabling the connection of the socket and the plug-in plug to provide a power supply. electric to the electrical load of use, the logic processing module delivering a control signal of the relay controlled now the disconnection of the plug and plug plug otherwise.

 The programmable power supply according to tariff orders, object of the invention, finds application to the distribution of electrical energy in domestic or industrial installations.

 It will be better understood by reading the description and by observing the following drawings in which: FIG. 1a shows, for illustrative purposes, a block diagram of the programmable power supply plug according to tariff orders in accordance with the object of the present invention; - Figure Ib represents, for illustrative purposes, a tariff order command signal transmitted on the sector; FIGS. 2a to 2d represent, for purely illustrative purposes, a plurality of screen pages implemented by a human-machine interface equipping a

<Desc / Clms Page number 7>

 tariff selection module by a user integrated in a programmable power supply socket according to the invention as shown in FIG. FIG. 3 represents, for purely illustrative purposes, a particular embodiment of the decoding module equipping the control chain included in the socket according to the invention as represented in FIG. FIG. 4 represents, for purely illustrative purposes, a particular embodiment of the comparison module of the logic processing module equipping the control chain included in the programmable power supply socket according to the invention as represented in FIG.

 A more detailed description of the power supply programmable according to tariff orders, according to the subject of the present invention, will now be given in connection with Figure la and the following figures.

 With reference to the aforementioned figure, it is indicated that the power supply, object of the present invention, comprises a plug 1 plug in a power outlet for example and a socket 2 connected to the plug 1 via plug via a controlled relay 3, this socket being intended to receive an electric charge of use.

 In addition, a chain 4 for controlling the controlled relay 3 is provided, the assembly being closed in a box B to constitute a set of programmable electrical power supply according to tariff orders directly plug in any power outlet of a

<Desc / Clms Page number 8>

 domestic or industrial installation, the assembly thus formed forming a particularly flexible use interface, the electrical load is then simply connected to the socket 2 after selection rate or consumption mode by the user, as it will be described below in the description.

 The control chain 4 of the controlled relay 3 comprises at least, as shown in FIG. 1a, a module 41 for detecting tariff orders issued on the sector via the plug 1. The detection module 41 is connected to the plug 1 plug and delivers a detected tariff order command signal, noted COTD in Figure 1 above.

 It will of course be understood that the connection of the detection module 41 to the plug-in plug 1 comprises all the necessary connections to the phase wire P and to the neutral wire N in order to ensure a low voltage or very low DC voltage supply of the electronic circuits. constituting the control chain 4. The aforementioned low-voltage power supply circuits will not be described because they correspond to elements known from the state of the art.

 The control chain 4 of the controlled relay 3 furthermore comprises, connected in cascade with the module 41 for detecting tariff orders, a module 42 for the logic processing of the detected tariff order command signal COTD. This logic processing module 42 comprises, as shown in FIG. 1a, a module 420 for the selection of tariffs applicable by a user. This selection module 420 allows this user to

<Desc / Clms Page number 9>

 program a predetermined tariff order code, noted TOC in Figure la, this predetermined tariff order code being selected from a plurality of specific tariff orders made available to each user by the distributor, as will be described later in the description.

 The logic processing module 42 also comprises a module 421 for comparing the predetermined tariff order code TOC delivered by the selection module 420 and the detected tariff order command signal, denoted COTD, delivered by the detection module 41.

 The logic processing module 42, by means of the comparison module 421, then delivers, on coincidence of the predetermined tariff order code TOC and the detected tariff order command signal COTD, a control signal of the controlled relay. signal being noted CR in FIG. The control signal CR allows the connection of the socket 2 and plug 1 plug via the controlled relay 3, to deliver a power supply to the electrical load of use, not shown in the drawing. The logic processing module 42 delivers on the contrary a control signal of the relay controlled maintaining the disconnection of the socket 2 and plug plug 1 in the absence of such coincidence.

 It is thus understood that, following the selection of a tariff and, consequently, of a specific tariff order by the user from the selection module 420, during the transmission on the distribution network or sector of a corresponding tariff order and on

<Desc / Clms Page number 10>

 coincidence of the predetermined tariff order code TOC and the corresponding detected tariff order command signal COTD, the distributor providing the consumption mode corresponding to the consumption mode chosen by the user, the controlled relay 3 ensures the connection of the socket female 2 and the plug 1 and thus the power supply of the electrical load of use in the consumption conditions provided by the distributor and chosen by the user.

 A more detailed description of the module 41 for detecting tariff orders issued on the sector will now be given with reference to FIG.

 In general, it is indicated that the module 41 for detecting tariff orders may comprise, as shown in the above figure, and connected in cascade, a filtering module 410 for extracting the mains supply voltage, from the plug 1, the frequency component of the tariff control signal. The filtering module is, by way of non-limiting example, constituted by a narrow-band bandpass filter, centered on the frequency Fo, ie on the carrier frequency, of the tariff order control signals. In the embodiment implemented by ELECTRICITE DE FRANCE, this frequency is equal to 175 Hz. The filtering module 410 delivers a baseband tariff control signal at the control frequency, this signal being denoted SBB on the basis of FIG. FIG. 1 and corresponding to successive pulses or bursts of signal with a carrier frequency Fo, as will be described later in the description.

<Desc / Clms Page number 11>

 The module 41 for detecting tariff orders further comprises a module 411 for decoding tariff orders receiving the SBB baseband rate command signal and delivering the detected tariff order command signal COTD previously mentioned in the description, according to a given tariff order code.

 With regard to the decoding module 411, the following general indications will be given.

 The decoding module 411 makes it possible to interpret the baseband signals at the frequency Fo in order to detect the transmitted tariff orders.

 As a non-limiting example, the code used by ELECTRICITE DE FRANCE is described below, any different code may, however, be used, these codes being of course equivalent.

 The remote control code making it possible to generate the base frequency signals SBB representative of the tariff orders may comprise 41 pulses constituting distinct signatures, the leading pulse constituting a so-called start pulse, this start pulse, denoted ID, which may be followed by an order pulse with which a specific tariff order is associated.

 Thus, in FIG. 1b, it is understood that each command pulse constitutes a direct encoding command following the start pulse ID.

 The timing diagram given in FIG. 1b makes it possible to summarize the transmission sequence of the pulse code at the frequency Fo.

 In the aforementioned FIG. 1b, the thick lines correspond to the value 0/1 of the pulse in the code.

<Desc / Clms Page number 12>

 The nominal duration of each pulse is 1 second taking as a time base the frequency of the electrical energy distribution network. In FIG. 1b, sr designates in fact the relative duration of each pulse related to the frequency of the distribution network.

commande Il par exemple, est de 3, 75 secondes. Le pas nominal des impulsions de commande suivantes est de 2,5 secondes. The nominal interval between the start of the start pulse, ID pulse, and the start of the pulse of

Il command for example, is 3, 75 seconds. The nominal pitch of the following control pulses is 2.5 seconds.

 The nominal duration of an emission cycle is thus 102.25 seconds, regardless of the pulses emitted.

 Under these conditions, it is understood that the position of each pulse with respect to the start pulse ID makes it possible to define a specific tariff order, the combination of two pulses for example, or if necessary of several pulses, in the duration of an emission cycle of 102.25 seconds, in particular the combination of the positions of these pulses, further allowing to define specific tariff orders, as will be described later in the description.

 The function of the decoding module 411 is then, from the baseband signals SBB at the frequency Fo, to elaborate the signature of the pulses present in the aforementioned transmission cycle and in particular the position of the latter with respect to the beginning impulse ID.

 A more specific description of the interpretation of the SBB baseband signals representative of the tariff orders by the

<Desc / Clms Page number 13>

 decoding 411 for the development of the predetermined tariff order code COTD will be given later in the description.

 A more detailed description of the user-selectable rate selection module 420 will now be given in conjunction with FIGS. 2a to 2d.

 By way of nonlimiting example, the selection module 420 may advantageously comprise, as shown in FIG. 2a, a liquid crystal display system E and selection buttons, these elements appearing directly on one of the two screens. external faces of the housing B.

 In a preferred embodiment, the selection module 420 thus comprises, thanks to the implementation of the liquid crystal display E and the selection buttons, a human-machine interface allowing the selection by the user of a tariff represented by a tariff code. Under these conditions, as shown in Figure 2a, the buttons may include a button on / off A / M and a tariff button "Tariff" allowing the user, following the start of operation of the set by actuation button A / M, the selection of a tariff by pressing the "Tariff" button.

 The successive actuation of the button A / M and the button "Tariff" makes it possible, as represented in FIG. 2b, the display on the liquid crystal display E, a drop-down menu of tariffs and an indication "Choice of the Tariff ".

A scroll button, denoted Def, is symbolized by a double arrow and allows the user to scroll through all the rates made available by the distributor, the proposed rate in the central area of the screen

<Desc / Clms Page number 14>

 for example, with the liquid crystal E being highlighted. Pressing the "Price" button selects the above rate. This selection then makes it possible, for the selected fare in question, for the selection module 420 to send the fare code, that is to say the predetermined fare order code TOC previously mentioned in the description. The aforesaid tariff code may be a serial number, coded in some way in binary code or other example.

 As shown in FIG. 2c, the aforementioned man-machine interface can advantageously allow the selection of a delay time at closing and / or opening of the controlled relay 3. For this purpose, as shown in FIG. 2c, and following the actuation of a button "Delay time" of the aforementioned man-machine interface shown in FIG. 2a, the liquid crystal display E makes it possible to display a screen for selecting a delay time on opening and / or closing, predetermined time values at the opening and / or closing can be scrolled via the scroll button Def. The selected predetermined time can be selected by pressing the "Delay time" button.

 Finally, the man-machine interface also allows the choice of an operating mode of the controlled relay 3, either closing or opening, or closing and opening.

 For this purpose, as shown in Figure 2d, and following the actuation of the open / close button designated OUV / FERM, the liquid crystal display E allows the display of different options opening,

<Desc / Clms Page number 15>

 closing and opening + closing. The selection of one of the possibilities can be done in the same way as in the case of the selection of tariffs, for example, and the validation of the selection from the aforementioned OPEN / CLOSE button.

Dans le tableau précité, la colonne de gauche désigne la position des impulsions ou ordres à codage direct de la figure Ib ou du code d'ordre tarifaire prédéterminé OCT et la colonne de droite désigne le tarif ou mode de consommation spécifique, proposé par le distributeur et correspondant à l'ordre tarifaire de la colonne de gauche.

In the aforementioned table, the left-hand column designates the position of the pulses or orders with direct coding of FIG. 1b or the predetermined tariff order code OCT and the right-hand column designates the tariff or specific consumption mode proposed by the distributor. and corresponding to the tariff order of the left column.

 When the user chooses, for example, on the man-machine interface, the tariff code A, the presence of the pulse Il in the list of pulses corresponding to the predetermined tariff order code TOC, and of course to the control signal Tariff orders detected COTD, then causes the closing of the controlled relay 3. For example, the presence of Il pulse 12 corresponding to the order 2 of the table causes on the contrary its opening.

 Such a table is therefore advantageously stored in a read-only type memory at the level of the selection module 420 for example, which allows the user, via the hommemachine interface previously described, to select the code of predetermined tariff orders COT supra.

 A more detailed description of the decoding module 411 will now be given in conjunction with FIG.

 In general, it is indicated with reference to the aforementioned figure, that the decoding module 411 may include, by way of non-limiting example, an envelope detector receiving the baseband signal SBB at the frequency Fo and delivering, for the cycle of pulses considered, a signal representative of the envelope of

<Desc / Clms Page number 18>

 the start pulse ID, followed for the considered cycle of one or more pulses, denoted nP in FIG. 3. A position detection circuit makes it possible, from a clock signal, for example CLK, to count the duration and therefore the position of each direct coding order, that is to say each pulse with respect to the ID start pulse. The position detection circuit can thus deliver the list of pulses present in the cycle, for example corresponding to a list of numbers, each number giving the position of the pulse or pulses present in the cycle with respect to the start pulse ID. . An encoder 411c receives the list of the aforementioned pulses and can thus transmit, by binary or other coding, according to a coding identical to the coding used to deliver the predetermined tariff order code TOC, the previously mentioned COTD detected tariff order command signal. .

 Finally, with reference to FIG. 4, the comparison module 421 may comprise a bit-to-bit comparator receiving, on the one hand, the predetermined tariff code COT delivered by the man-machine interface 420, and on the other hand On the other hand, the tariff order command signal detected TOC. On coincidence of the two aforementioned signals, the bit-to-bit comparator can then deliver a logic signal for controlling the LCR relay, which, controlling a power module for example, makes it possible to deliver the control signal of the controlled relay, signal CR previously described in FIG. the description.

 The power supply programmable according to tariff orders, object of the present invention, can of course be used in all types

<Desc / Clms Page number 19>

 electrical installations, but in particular in domestic electrical installations for controlling the starting of electric charges for use, such as washing machines, dryers or other low-cost pricing. It has a great flexibility of use, since by simply plugging into a conventional outlet and then selecting a rate or a mode of consumption, it is possible to benefit from the specific consumption modes offered by the distributors without having there is no need to install new wiring in the domestic installation and therefore incur additional significant costs.
