Description

The invention relates to the field of electrical installations, and more specifically to a power strip allowing an electric energy consumer to monitor and manage its consumption. BACKGROUND OF THE INVENTION Electric power providers provide subscribers - electricity consumers - with electricity meters that can be equipped with management electronics.

In addition, the electrical installation of a home is usually equipped with an electrical panel that includes the shutdown commands of the housing electrical circuits, circuit protection systems and protections specific to people. The electrical panel can also integrate a local energy management system consumed, ie allowing a programming of the uses of the apparatus of the installation according to a parameterization of the consumer or according to instructions of teleinformation delivered by the electric meter according to the subscribed subscription. Electric power providers seek to regulate and anticipate electricity consumption among subscribers. Indeed, the current means of electricity production react with difficulty to large variations in energy demand. Electric power suppliers therefore seek to collect information on consumption from a subscriber to regulate its consumption by remote information commands from the meter. There are thus "box-" including modules of information taken at a subscriber and communicating information to the service provider. Existing systems are not controlled by the subscriber but by the service provider, and only allow partial collection of information. In addition, the electrical panel belongs to the owner of the housing. In the case of rented accommodation, the tenant can access the information collected by the electrical panel if necessary. Nevertheless, if the electrical panel is of a type that does not allow any collection of information on the electrical uses in the dwelling - for the sake of saving the owner - the user of the housing can not control or manage its electrical uses. There is therefore a need for a system installed in a consumer and controlled by the latter, which allows to collect a set of information on the uses of this consumer and keep this information available to the consumer. For this purpose, the invention proposes an electric power strip for a detailed measurement of the power consumption of the devices connected to this power strip and to locally store the measured data for use at the discretion of the consumer. The power strip can thus become a link in a housing service platform, in place of or in addition to the meter controlled by the electric power supplier and / or in place of or in addition to the electrical panel.

More particularly, the invention relates to an electrical power strip, comprising: at least one current sensor per tap, adapted to measure a current flow and a potential difference; an electronic processing unit adapted to collect data from each current sensor; an electronic memory adapted to archive the collected data of each current sensor; at least one communication interface. According to the embodiments, the power strip according to the invention can comprise one or more of the following characteristics: the electronic processing unit is adapted to collect and archive in addition data from at least one domestic sensor; the electronic processing unit is adapted to transmit, on request, collected and archived data; the electronic processing unit is set to detect operating anomalies from the data collected and adapted to issue an alert; the communication interface makes it possible to consult all the data collected and archived; the communication interface is at least one of a radio connection, a WiFi connection, a CPL connection; an autonomous power source; The invention further relates to a domestic electrical installation comprising at least one power strip according to the invention. The installation may furthermore comprise at least one home sensor and / or at least one device comprising a software application making it possible to consult all the collected and archived data. The installation according to the invention may furthermore comprise at least one tap comprising: at least one current sensor adapted to measure a current start and a potential difference; an electronic processing unit adapted to collect data from the current sensor; an electronic memory archiving the collected data of the current sensor; at least one communication interface. The electronic processing unit of the socket can be adapted to collect and archive in addition data from at least one home sensor. The invention also relates to a method for controlling a domestic electrical installation according to the invention, the method comprising the steps of: collecting and archiving sensor data; transmission, upon request, of data collected and archived; consultation, on request, of data collected and archived. The method according to the invention may further comprise the steps of: monitoring the collected data to detect operating anomalies; issuing an alert in case of anomaly detected. If the installation comprises a plurality of electronic processing units, the method may further comprise the step of selecting one of the units as a master unit. Other features and advantages of the invention will appear on reading the detailed description below, and the appended figures which represent: FIG. 1, an electrical power strip according to the invention; FIG. 2, an example of an installation comprising a power strip according to the invention. Figure 1 shows a power strip 200 installed in a housing of a consumer of electrical energy, that is to say downstream of an electric meter and an electrical panel.

The power strip 200 according to the invention comprises at least one current sensor 201 per socket. It is possible to place two current sensors to measure on the one hand a departure and on the other hand a current return. The current sensors 201 are thus adapted to measure a current flow and a potential difference at each tap. Any electrical fault occurring in the appliance connected to one of the sockets can thus be detected by means of these sensors 201 and the fault can be located in the housing according to the associated socket. The power strip may also include a differential circuit breaker, for example at 30 mA, providing protection for people by detecting ground leakage in the electrical installation. The power strip 200 according to the invention further comprises an electronic processing unit 202 collecting data from each current sensor 201. This data is collected and archived in a memory in the power strip. Such memory can be a "microSD" card (Secure Digital Microcard) inserted in the power strip. The power strip 200 thus constitutes a "black box" for the electrical uses of the devices connected to this power strip. The current sensors 201 collect information relating to the consumption of each appliance or group of appliances connected to one of the outlets and the electronic processing unit 202 collects and stores this data. The consumer can then choose how he has this information collected and archived. In particular, the power strip 200 comprises at least one communication interface 203. Such a communication interface 203 may be a radio connection, a WiFi connection, a CPL connection (Line Carrier Current) or any other interface allowing the consumer to consult the information. collected and archived and / or allowing a transfer of this information to an outdoor unit. For example, the data collected and stored in the memory of the power strip 200 can be duplicated automatically to the electrical panel of the housing or to a secure electronic safe with a frequency determined according to a consumer setting. The data collected and stored in the memory of the power strip 200 can be transferred or consulted, on request, from a computer or any other device provided with appropriate software. The communication interface 203 may also make it possible to collect additional information in the installation, as will be described with reference to FIG. 2.

The power strip 200 according to the invention allows a consumer to control some of its electrical uses and to keep a history of these uses. For example, the data collected by the current sensors 201 and stored in the memory of the power strip can be viewed by the consumer (owner and master of the power strip unlike the meter that is controlled by the electric power supplier) and transmitted to outside on request of the consumer. The request for external transmission of the collected data may be one-off or the fact of a configuration by the consumer, for a regular backup of the data for example. The electrical uses of the consumer can thus be kept outside the home and reconstituted, for example to assist the consumer in optimizing his power consumption and / or to help establish causes of failure in the event of a disaster. According to one embodiment, the electronic processing unit 201 may also be parameterized to detect operating anomalies from the collected data, in particular the tripping of the differential circuit breaker and / or the non-operation of an apparatus. The electronic processing unit 201 can then issue an alert to the consumer via the communication interface 203. FIG. 2 shows an installation comprising the power strip 200 described with reference to FIG.

Figure 2 shows a plurality of household sensors 150. These household sensors 150 may be installed in the housing at the discretion of the consumer; they can include sensors for humidity, smoke, air quality, brightness, motion or other. The electronic processing unit 202 of the power strip 200 can also collect and archive this data collected by the home sensors 150. A radio channel of the communication interface 203 of the power strip 200 can for example be used for this purpose. The data thus collected from the domestic sensors 150 are also stored in the memory of the power strip 200, in the same way as the data collected from the current sensors 201, and can be consulted by the consumer and transmitted to the outside at the request of the consumer. These data collected from the domestic sensors 150 are integrated in the history of the uses of the housing and can then be used as needed to reconstruct events occurring in the dwelling. According to one embodiment, the electronic processing unit 202 can also be parameterized to detect operating anomalies from the data collected from the domestic sensors 150, for example an air quality fault or an intrusion detection. The electronic processing unit 202 can then issue an alert to the consumer or to a third party via the communication interface 203. If the installation comprises a plurality of power strips 200, that is to say a plurality of electronic processing units 202, one of the units can then be chosen as the master unit of a geographical area. The master unit can collect the data from the home sensors 150 and / or collect all the data collected by the other electronic processing units of the other multi-companies of this geographical area. In case of failure of the master unit, another of the operational electronic processing units of this geographical area can be elected as the master unit according to communication methods between electronic units known per se. The data collected by each power strip 200 can be transmitted to an electrical panel 100 of the housing provided with a communication interface 115, especially when the consumer can also control the electrical panel (in the case of a homeowner, for example) . The electrical panel 100 may comprise an electronic processing unit collecting all of the data collected by a plurality of power strips 200 according to the invention and consolidating these data for archiving and transmission to the outside of the housing. For example, the electronic processing unit 202 of the power strip 200 can transmit to the electronic processing unit of the table 100 all of its collected and archived data - data collected by each current sensor 201 and data collected from the domestic sensors. 150 local. The consumer can access the data collected by the power strip 200 either by the board, or directly by interrogating the power strip using a communicating device 30 (tablet, PC, smartphone or other) equipped with appropriate software. The data collected and stored in the memory of each power strip 200 can be regularly transmitted to the electrical panel and / or duplicated automatically in a secure electronic safe box 50 with a frequency determined according to a parameterization of the consumer. The electrical panel may have a USB port to enable updating and / or maintenance of the software of the electronic processing unit 202 of the power strips 200. A human-machine interface (HMI) may allow an in situ consultation of the data collected and archived by the electronic processing unit of the table after authentication of the consumer (entered with a code and / or a biometric data for example) and / or to allow a configuration by the consumer. The setting of the power strips 200 can also be carried out by the consumer using a device communicating via Wifi, CPL or radio, via the interface 203 of the power strip 200. Such a device 30 can be a tablet, an PC, Smartphone or other, equipped with a suitable software. FIG. 2 also shows a tap 300 comprising at least one current sensor 301 adapted to measure a current start and a potential difference. The outlet 300 also comprises an electronic processing unit 302 collecting data from the current sensor 301 and a memory archiving the data thus collected. The socket further comprises at least one communication interface 303, which may be a radio connection, a WiFi connection, a CPL connection (Line Carrier Current) or any other interface allowing the consumer to consult the collected and archived information and / or allowing a transfer of this information to an outdoor unit.

As described above with reference to the power strip 200, the socket 300 can also relay the collection of data from household sensors 150. All the data collected by the socket 300 - data of the current sensors 301 and data collected from the domestic sensors 150 premises can be transmitted to the electronic processing unit of table 100 and / or to the electronic processing unit of a power strip 200 according to the invention. The data collected by the socket 300 can also be accessed locally in the socket 300 by the consumer using a communicating device 30 provided with a suitable software. The power strip 200 according to the invention can be used to control a domestic electrical installation.

Such a control includes the collection of data from sensors 150, 201, 301 (current sensors and domestic sensors if necessary, centralized collection at a power strip and collection relayed by local outlets and / or outlets where appropriate) and archiving this data (in the memory of each power strip 200 and in the memories of each socket 300 if necessary). The collected data can be time stamped by the electronic processing unit 202, 302 ensuring archiving. The existing solutions, limited in user consumption measurement points, do not make it possible to deal with the electrical safety, comfort and quality of well-being of the occupants of a dwelling. If several electronic processing units 202, 302 are involved in the collection and archiving of sensor data, a step of choosing a master unit can be performed to coordinate the collection and archiving of data of this geographical area, as well as the consultation of the archived data and their transmission to the outside. The election of an electronic processing unit as the master unit can be done in any manner known per se. If the chosen master unit were to fail, a new election of a master unit among the operational electronic units of that geographical area would take place, in a manner known per se. The control of an electrical installation according to the invention also comprises the transmission and / or consultation, on request, of the collected and archived data. For example, the collected data are stored on a card! .. tSD directly in each memory of the electronic processing units, for a predetermined sliding duration (a few weeks or a few months depending on the settings). This data can then be cyclically duplicated in a secure electronic safe 50 outside the housing, without limitation of duration. The transfer of this data can be encrypted and transmitted via a telecom box 20 with an ADSL link. Such a telecom box 20 comprises a communication interface 21 which can communicate with the communication interface 203, 303 of each power strip 200 and socket 300. Where appropriate, the telecom box 20 can also communicate with the communication interface 115 of the table 100 in Wifi or via an Ethernet cable. In the case of a general power outage, each electronic processing unit may have sufficient autonomy to back up the data and send an alert to the consumer or a third party. An automatic device can then put the sensors to sleep and interrupt data collection. An independent power source can be provided in the power strip 200 to maintain the detection of anomalies in the housing in the event of a general power failure. For example, the power strip 200 may include a rechargeable battery ensuring degraded operation in the absence of external power supply (for example in the event of total loss of power supplies (12V DC on mains)). Existing solutions do not work in degraded mode. If the "box-" breaks down, no function is ensured. The consumer may also require, by means of a communicating device provided with appropriate software (Smartphone 30 for example, PC or other), to consult the data archived in each of the memories of the electronic processing units of the power strips 200. interface 203 makes it possible to read the collected data, to process it, to format it to allow the installation of personalized added value services. The interface 203 also allows a consumer to parameterize the power strip 200 according to the invention. The parameterization of each power strip 200 may include the following information: the upstream rating of the circuit breaker of the electrical panel (10A, 16A, ...) and the name of the outlet with which it is associated, the connected equipment (TV, DVD player, computer ....), the date and time, the geographical position in the housing, the configuration of the communication interfaces, the configuration of the connection with the electronic unit of the electrical panel, if any, - the configuration of the connection with the housing sensors, if applicable: type of sensor, network address, geographical location .... The current measurements of each socket of the power strip 200 collect detailed consumption information. This information allows consumers to become aware of, manage and optimize their energy consumption in their home and have access to a detailed report of their electricity consumption (just like a telecommunication bill or a bill of exchange). monthly bank statement of his transactions). Existing solutions centralize information on external servers controlled by service providers to create service platforms: they are intrusive solutions where the consumer does not have the control of his data.

The control of an electrical installation according to the invention also includes the monitoring of the collected data to detect operating anomalies and the issuance of an alert in the event of a detected anomaly. Each electronic processing unit 202 can be parameterized to detect anomalies in the data collected from the sensors 201, 150. It can then send alerts to the consumer or to a third party parameterized on triggering events that can be: tripping of the differential circuit breaker 30 mA of the power strip, on current leakage fault on equipment, - tripping of the intrusion alarm, - lack of air quality, temperature, humidity, water leakage ... inactivity (for example, monitoring an elderly person). Existing solutions do not address electrical safety and are still limited in the treatment of the environmental quality of a home. In case of total loss of power supplies (12V DC on mains) with battery passage in a socket 300 or 200 power strip, a first message can be sent on one of the consumer interfaces and a second message can be sent to the unit electronic treatment of electrical panel 100 housing, if any. The consumer can thus manage in a personalized way his electrical uses and keep in a secure way a history of data related to his housing. The invention has been described with reference to particular embodiments that are not limiting. In particular, the number and nature of the sensors may vary according to the applications, as well as the modes of transmission and consultation of the collected data.
