Description

DEVICE AND METHOD FOR STORING AND SHARING DATA OF OBJECTS CONNECTED TO AN INTERNET NETWORK, AND PROCESS FOR RETRIEVING DATA FROM CONNECTED OBJECTS

The invention relates to a device and a method for storing and sharing data of objects connected to an Internet network in a local area network, and a method for retrieving data from objects connected to an Internet network.

The field of connected objects is expanding. Multiple connected objects invest our environment: home, office, our person ... These are particularly communicating sensors such as thermostats, weather station, bathroom scale ....

The Internet of Things is a fast-growing sector that brings out many players offering a multitude of connected objects. Connected objects are therefore designed and supplied by a wide variety of companies. Each supplier of connected objects generally develops its own device for consulting and controlling these connected objects (its own application and / or its own user interface) and uses communication protocols that are proprietary or conform to a standard such as as LoRa, SigFox, etc. Thus, users must adapt to each application if they have multiple objects because the connected objects are not interoperable.

One of the aims of the present invention is to provide improvements over the state of the art.

An object of the invention is a device for storing and sharing data of objects connected to an Internet network, the storage and sharing device being implemented in a local network and able to allow a control device connected to the network. local to browse the stored data and control the reading of a selected data in the storage device and data sharing by a rendering device connected to the local network, the data storage and sharing device having several interfaces of loading data relating to different communication protocols, each interface being configured to receive, in a communication protocol specific to said interface, data from at least one object connected to the Internet network.

Thus, a communication terminal can access through a single device data from all of its connected objects even when they use separate communication protocols and / or when the communication terminal does not use the protocol of communication of the connected object whose data are consulted by the terminal. Advantageously, the data storage and sharing device records all the data received from a connected object in the same set of data.

Thus, the delay of viewing data from an object connected in the storage and sharing device is reduced because the terminal consults a set stored in this device and not several data stored separately.

Advantageously, the data storage and sharing device records in association with data received from a connected object a data identifier.

Thus, the device for storing and sharing data makes it possible to consult the data not only by object but also by type of data, for example by searching among the data stored on the identifier. Advantageously, the data storage and sharing device comprises an aggregator of the data coming from several objects connected via the separate loading interfaces.

Thus, the terminal viewing the data stored in the storage device receives aggregate information including all the stored data consulted thereby reducing the resources required for the transmission of data accessed between the storage device and sharing and the terminal. In addition, this simplifies the use of the data consulted by the terminal, especially when the terminal includes a playback device, the playback device comprises a reproducer of the aggregated information received but no processing device for formatting several data received from possibly more than one object.

Advantageously, the storage device and data sharing is a media server complying with the DLNA standard.

Thus, storing and sharing data from connected objects shares the same infrastructure as storage and sharing of multimedia data reducing the number of devices in a local area network and connected to the local network. Indeed, either a specific storage and sharing device for the connected object data is added to the architecture, that is a multimedia data storage and sharing device, also called a media server in the DLNA, UPnP and equivalent standards. , is adapted to include storage-specific loading interfaces and sharing data of connected objects.

An object of the invention is also a method of storing and sharing data of connected objects, the storage and sharing method being implemented in a local network and allowing, by means of a control device connected to the local network, to navigate among the stored data and to control the reading of a selected data by a rendering device connected to the local network, the method of storage and sharing of data data comprising several data loadings relating to different communication protocols, each load making it possible to receive, in a communication protocol specific to said loading, data from at least one object connected to the Internet network.

Advantageously, the method of storing and sharing data comprises a periodic triggering of the data loading of a connected object.

Thus, the stored data corresponds to the current value of the data of the connected object.

Advantageously, the data loading comprises a monitoring of the transmissions of the connected object triggering the reception of the data transmitted by the connected object.

Thus, the resources of the storage and sharing device are activated only when they are used in particular for receiving data of connected objects. Advantageously, the loading is carried out directly from the connected object.

Thus, the transmission errors are reduced since the data is transmitted directly from the connected object to the storage and sharing device without intermediary. Advantageously, an alternative proposes that the loading be carried out from a mediation device that has received the data of the connected object.

Thus, the resources of the connected object are optimized since, if it performs a loading on a mediation device connected to the Internet, the connected object will not have to retransmit the same data, but they will be loaded by the device storage and sharing from the mediation device having already received them.

Advantageously, according to an implementation of the invention, the various steps of the method according to the invention are implemented by a software or computer program, this software comprising software instructions intended to be executed by a data processor of a computer. device for storing and sharing data of connected objects and being designed to control the execution of the various steps of this method. The invention therefore also relates to a program comprising program code instructions for executing the steps of the method of storing and sharing data when said program is executed by a processor. An object of the invention is also a method of restoring data from connected objects to a rendering device connected to a local area network, the rendering method comprising a reading of selected data from data stored by a storage device and of data sharing having received the data of objects connected to the Internet network by means of loading interfaces of the storage and data sharing device relating to separate communication protocols, the reading having been controlled by a connected control device the local network, the control device for navigating and selecting from the stored data.

Advantageously, the data restitution method is implemented by a media rendering device of a DLNA type local network architecture.

Advantageously, according to an implementation of the invention, the various steps of the method according to the invention are implemented by a software or computer program, this software comprising software instructions intended to be executed by a data processor of a computer. device forming part of a communication terminal and being designed to control the execution of the various steps of this method.

The invention therefore also relates to a program comprising program code instructions for executing the steps of the data restitution method when said program is executed by a processor.

These programs may use any programming language and be in the form of source code, object code or intermediate code between source code and object code such as in a partially compiled form or in any other desirable form.

The invention provides a unified user experience for viewing data provided by objects connected to a home network. It relies on a protocol implementing a storage and sharing device, such as UPnP, DLNA or an equivalent standard. In particular, it extends the functionality of the storage and sharing device, also referred to as a media server, in order to provide data from the connected objects. The user can, in particular, use any control device, also called "control point" (English) or digital media controller (DMC), DMC in these standards, as a TV, smartphone, etc. he is used to consuming audio and / or video content to view data from sensors connected to the home network, including sensors from his home (humidity, temperature, electricity meter ...). The data will then be rendered on a rendering device, also called digital media player (Digital Media Player or Renderer, in English), DMP or DMR in these standards. FIG. 1 illustrates a communication architecture comprising a storage and sharing device according to the invention.

The storage and sharing device 2 according to the invention is a particular storage and sharing device, also called media server for connected object (Media Server for loT, in English: MSJoT). It is in particular responsible for aggregating the data of several connected objects using in particular several distinct communication protocols.

The device 2 for storing and sharing data of objects connected to an Internet network is implemented in a local area network. It is configured to allow a control device 10 connected to the local network to navigate among the stored data and to control the reading of a selected data item in the data storage and sharing device 2 by a connected reproduction device 11. to the local network. The data storage and sharing device comprises several data loading interfaces 20 20 ₂ , 20 _N relating to different communication protocols. Each interface 20 20 ₂ , 20 _N receives data of _{1 ti} , of ₂₁ j ... do ₂ M, j, do _NJ of at least one object 4 4 ₂₁ ... 4 _2M , 4 _N connected to the Internet network .

The loading interfaces are notably implemented in the form of a plugin. The role of the load interface is to enrich the storage and sharing device with data collected from connected objects using separate communication protocols. Let's take a first load interface 20 ^ relating to a first connected object 4 it implements the communication protocol of the first connected object, hereafter called the first communication protocol. For example, first load interface 201 includes a data receiver using this first communication protocol. Thus, the first load interface collects data from the first connected object and also possibly other connected objects using the same first communication protocol.

A loading interface can optionally receive the data of a single type of object, of several types of connected objects using the same communication protocol (proprietary protocol: several objects of the same brand, protocol conforming to a standard: for example, LoRa).

In particular, the data storage and sharing device 2 comprises an aggregator 23 of the data of _{1 ti} , of ₂₁ j ... ₂ Mj, do _N , i coming from several objects connected via the separate loading interfaces.

In particular, the storage and data sharing device 2 stores all the data {do ^} ,, {do ₂₁ j} j ... {do ₂ Mj} j, {do _NJ } i received from a connected object. , respectively 4 4 ₂₁ ... 4 _2M , 4 _N , in the same set of data E ^ E ₂₁ ... E _2M , E _N. In particular, the data storage and sharing device 2 is a media server complying with a standard of the DLNA or UPnP type.

FIG. 1 shows a communication architecture comprising, in addition to the storage and sharing device, in particular:

- Connected objects 4 4 ₂₁ ... 4 _2M , 4 _N.

A control device 10;

A restitution device 1 1.

Optionally, a communication terminal 1 comprises the control device 1 and / or the reproduction device 1 1.

The storage and sharing device 2 comprises several charging interfaces 201, 20 ₂ , 20 _N. It comprises, in particular, a loading interface by communication protocol. Thus, a loading interface 20 _! , 20 _N , respectively 20 _2i can receive data from a single connected object 4 ~ _\ , 4 _N or more connected objects 4 ₂₁ ... 4 _2M .

The loading interfaces 20 20 ₂ , 20 _N receive the data either directly from the connected objects 4 4 ₂ I ... 4 ₂ , 4N as shown in FIG. 1, or via a mediation device 3n (not illustrated in FIG. ). In particular, a connected object 4 _n to an Internet network transmits its data to a mediation device 3 _n connected to the Internet network. The storage and sharing device 2 of the local network will receive the data of the connected object 4 _n transmitted by the mediation device 3n connected to the local network. Thus, the connected objects 4 4 4 ₂₁ ... _2M, 4 _N can be implemented within or outside the LAN. A mediation device 3 _n connected to the local network for relaying their data do _nk to the storage and sharing device 2.

The storage and sharing device 2 comprises in particular a memory 21, such as a database, in which the data {do ^} ,, {do ₂₁ j} j ... {do ₂ Mj} j, {do _N , i} i from the connected objects 4 4 ₂₁ ... 4 _2M , 4 _N are recorded. Thus, the loading interface provisions the memory 21, in particular the database of the "Content Directory Service" of the media server according to the DLNA standard, UPnP or equivalent, with the data collected.

In the case where the storage and sharing device 2 of data coming from connected objects 4 4 ₂ ... 4 ₂ 4 is a multimedia data storage and sharing device, the memory 21 is a first memory allowing the storage of the data. recording of data {do _{1 ti} } i, {do ₂₁ j} j ... {do _2M j} j, {do _NJ } i from connected objects 4 4 ₂₁ ... 4 _2M , 4 _N and the storage and sharing device 2 comprises a second memory (not shown) for the recording of the multimedia data, or the multimedia data are also stored in the memory 21.

In particular, the storage and sharing device 2 comprises a sharing interface 22 receiving requests, respectively reqc, reqd, of a control device 10. In particular, the sharing interface 22 searches and reads in the memory 21 is the available data id_rd which it transmits at least the nav identifiers to the control device 1 0, the selected data d_rd, for example among those which he received the identifiers nav, by the control device.

In the case where the sharing interface 22 searches for the data selected by the control device 10, in particular, following a command reqd of the control device 10, the data read {do _ap } by the sharing interface 22 in the memory 21 are transmitted to an aggregator 23. After generation of aggregated information da by the aggregator 23 from the read data {do _ap }, the aggregated information da is transmitted directly to a reproduction device 11, either an add address, for example in the memory 21 or another memory of the storage and sharing device 2 in which the aggregated information da generated by the aggregator 23 can be accessed rd (add) by the restitution device 1 1 is transmitted to the control device 1 0.

When using the UPnP protocol, the aggregator 23 notably provides an item such as:

<dc: title> 1200 kWh </ dc: title>

<Upnp: class> object.item </ upnp: class>

</ Item> whose main property is the title of the item since it represents the data to be restored by the rendering device 1 1. It is a generic item with no particular type, neither audio nor video ... to which no resource is associated because there is no content to consume. FIG. 2 illustrates an example of recording of data coming from objects connected by a storage and sharing device according to the invention.

In particular, the data storage and sharing device 2 _stores all the received data {do _nJ } i of a connected object 4 _n in the same set of data E _n , for example the same container or the same directory in the memory 21.

In particular, the data storage and sharing device 2 records in association with a data received from a connected object a data identifier id _nJ . Thus, the storage and sharing device 2 bridges the different proprietary or standard protocols of the connected objects and the communication protocol used by the local network, notably DLNA, UPnP, or equivalent standard in order to exploit the data coming from the connected objects and return them to control devices, rendering device and other communication terminals.

When the storage and sharing device 2 according to the invention complies with one of the UPnP, DLNA or equivalent standards, it can then rely on discovery protocols (eg SSDP), navigation protocols (eg browsing) and notification (eg GENA) equivalents. FIG. 2 shows an exemplary set of data items of an object 4n stored in the memory 21 in the form of a directory. The received data of _{n 1} , do _{n 2} ..., do _nJ of the connected object 4n are associated with a data identifier, respectively id _n , i, id _{n, 2} ..., id _n j. For example, they are recorded in the same file, respectively f _n , i, f _n , 2 - - -, f _n , i. Consider a home network with 2 connected objects: an electrical meter providing the household's power consumption and a temperature and humidity sensor. Data from connected objects can be written as follows in the storage and sharing device:

In a first container associated with a data identifier "R ELECTRIC ACCOUNT", a data "1200kWh";

In a second container associated with a "NetAtmo sensors" data identifier, two files:

o A first file in which is registered an identifier of the data "temperature" and its value "21 ° C": "temperature 21 ° C", and o A second file in which is registered an identifier of the data "Humidity" and its value "50%": "Humidity 50%"

In particular, the data do " _, i (t) coming from a connected object are recorded by overwriting the previous data do _ni (tT) corresponding to the same associated identifier id" _, i in the memory 21. Thus, the saturation of the memory is avoided.

Alternatively, when data do _nJ (t) are received repeatedly, including periodically, 4n of a connected object, they can be stored in association with a _nJ id data identifier in addition to data already stored do _nJ ( tT) in association with this same identifier id _n , for example in the same file f _ni . Thus, a history of the data from one or more connected objects can be consulted and possibly calculations performed, including statistics, on the evolution of these data in particular to control a rendering device.

For example, connected objects consist of different sensors for temperature, humidity and sunshine in several rooms of a building and possibly outside, the evolution of the data will eventually allow the control of the heating system, the windows , shutters, watering and various other controllable building devices in anticipation and not afterwards.

Figure 3 illustrates a simplified diagram of a method of storage and sharing according to the invention. The method of storing and sharing S & SH data of connected objects is implemented in a local area network. It allows, by means of a control device 10 connected to the local network, to navigate among the stored data and to control the reading of a selected data by a rendering device 1 1 connected to the local network. The method of storing and sharing S & SH data includes several CHGTn data loadings, n = 1 ... N, N> 2 relating to separate communication protocols. Each load CHGTn can receive, in a communication protocol own loading, data of at least one OCn connected object to the Internet.

In particular, the S & SH data storage and sharing method comprises a periodic cht_trg trigger Tn of the data loading CHGTn of a connected object OCn. In particular, the method of storing and sharing S & SH data includes an end-of-period check tn = aTn? a being an integer and n = 1 ..N at each moment tn. If the end of period is reached [Y], it triggers the loading chgt_trg. If not [N], it goes to the next instant tn = tn + 1. In particular, the data loading CHGTn comprises a OC_MNT emission monitoring of the object connected OCn triggering the reception data transmitted OC_REC do _nJ by OCn connected object. In particular, the CHGTn is loaded directly from the connected object OCn. As an alternative to direct loading, the CHGTn is loaded from a mediation device DMn that has received the data from the connected object OCn.

The loading of data CHGTn includes monitoring especially when the connected object OCn or the mediation device DMn automatically transmits the data, that is to say that it operates in so-called "push" mode.

Alternatively, the data loading CHGTn includes an OC_REQ data request either directly to a connected object OCn or to a mediation device DMn which sends a request dOn_req to the device concerned. The connected object OCn or the mediation device DMn receiving the request will issue dOn_req then the data of _nJ . It is said that it operates in "pull" mode.

In particular, the method of storage and sharing S & SH includes an audit En? the existence of a set of data associated with the connected object in the BDD memory. If no set exists [N], the storage and sharing method comprises creating a set En_CREA associated with the object OCn and recorded w (En) in the memory BDD, in particular in the form of a container or a directory. If a set exists [Y], the method of storage and sharing searches, in particular, an identifier ID_SRCH? corresponding to the received data of _nJ of the connected object in the set En. If this identifier does not exist [N] or if no set exists [N], the storage and sharing method comprises an association of an identifier ID_ASS with the received data of _n , i, in particular by writing x ( id _nor 3En) of the identifier in the set En of the BDD memory.

In particular, the method of storage and sharing S & SH includes a record of the received data of _n , i, in particular by writing this data in the BDD memory. Optionally, the received data of _n , i, is written in association with an identifier w (do _n , i <→ id _n j), for example in a file, in a set In, or in a file of the set In in the BDD memory including the identifier. In particular, if the search finds ID_SRCH [Y] identifier in the database memory, the data received do _nJ is written in association with the identifier found w (do _n, i <id → _n, i) in the memory BDD.

In particular, the S & SH storage and sharing method comprises, during a consultation of the stored data, an AGGT aggregation of the data consulted. For example, a DC control device transmits a data request reqd to read selected stored data. Aggregation AGGT retrieves data stored in the memory according to the received data request reqd and generates aggregated information da which is transmitted to a rendering device DR.

Optionally, the S & SH storage and sharing method comprises a generation NAV_GN of a navigation page from the identifiers of the data stored in the memory (not shown). This generation ANV_GN is triggered in particular by receiving a request for consultation reqc from a DC control device. In particular, the S & SH storage and sharing method includes a transmission of the generated nav navigation page to the control device. Thus, the control device DC or a user of the control device by means of a human-machine interface of the control device can select from this navigation page nav data from the data stored in the BDD memory. The data on this page includes raw data without formatting.

The storage and sharing method may be implemented by a program comprising program code instructions for performing the steps of the method of storing and sharing data when said program is executed by a processor.

FIG. 4 illustrates a simplified diagram of a method for restoring data from connected objects according to the invention.

The method of restoring ROC data from connected objects to a rendering device connected to a local area network comprises an OC_RD reading of data selected from data stored by a storage and data sharing device having received these object data. connected to the Internet through storage and data-sharing loading interfaces. The reading OC_RD is controlled by a DC control device connected to the local network, the DC control device for navigating and selecting among the stored data.

In particular, the method of restoring the ROC data is implemented by a media rendering device of a LAN network architecture of the DLNA or UPnP type. In particular, the control device sends a request for reqd data to the storage and sharing device DSSH which

or directly transmits an aggregate information da comprising the required data da = {do _nJ } to the OCR retrieval process that reads OC_RD aggregated information da, or transmits an add (da) address to the control device DC, address to which the aggregated information can be read. The control device DC command cmd (add) then the reading OC_RD of the aggregated information. Reading OC_RD consults req (add) the provided address and reads the aggregate information da.

In particular, the ROC restitution method comprises an RPR reproduction of the aggregated information.

In particular, the ROC restitution method may also comprise a calculation (not shown) as a function of the aggregated information, in particular enabling control of remotely controllable objects (at least in a local network).

An embodiment of the rendering method is a program comprising program code instructions for executing the steps of the data restitution method when said program is executed by a processor.

FIG. 5 illustrates a simplified exchange diagram during the implementation of a storage and sharing method, and a rendering method according to the invention. The connected objects 0 ₁₁ (4 ₁₁ ), 0 ₁₂ (4 ₁₂ ) use the same communication protocol. These connected objects 0 ₁₁ (4 ₁₁ ), 0 ₁₂ (4 ₁₂ ) and the connected objects 0 ₂ ... 0 _N are either implemented or connected to the same local network for example via an Internet network. The connected object O _n (4 _n ) not shown in the figure is connected to the Internet, it transmits via the Internet network data _nJ to a mediation device DMn.

A storage and sharing device DSSH (2) is implemented in the local network. It implements a method of storage and sharing. In particular, it implements several CHGT1, CHGT2 loadings:

A load CHGT1 which receives the data of ^n (tn), 12 _12j , Onn + nn) of the connected objects 1 _{1 1} (4 _{1 1} ) and _{12 12} (4 ₁₂ ) using the same communication protocol,

A load CHGT2 which receives the data of _{2 k} from the connected object 0 ₂ (4 ₂ ),

• etc.

A loading CHGTn (not shown) which receives from the mediation device DMn the data of _nJ coming from the connected object O _n (4 _n ),

· Etc.

• a CHGTN load (not shown) which receives the data of _{N, P} of the connected object 0 _N (4 _N ).

This data is memorized DO_MEM in the storage and sharing device

HHS (2). Optionally, the loading CHGT1, CHGT2 ... requires do11_req, do2_req the data from the connected objects, respectively On and 0 ₂ which transmit the data following the reception of this request. In particular, the CHGT1 loading is performed periodically (the period illustrated is equal to Tu).

A DC control device (10) including a communication terminal 1 may require reqc consultation of data stored with the DSSH storage and sharing device which will return including a nav navigation page.

The DC control device (10) may in particular require reqd data stored at the DSSH storage and sharing device, in particular selected from a navigation page previously received nav. The storage and sharing device DSSH reads the required data and transmits them to a DR rendering device, particularly in the form of aggregated information. In particular, the DSSH storage and sharing device implements an aggregation of the required read data and provides the aggregated information.

For example, either the DSSH storage and sharing device sends to the control device an add (da) address to which the aggregated information is searchable (the control device DC will then command cmd (add) reading OC_RD this address by the DR rendering device which will require req (add) reading of the address, or the DSSH storage and sharing device sends the aggregated information da directly to the DR rendering device which will read it OC_RD before possibly reproducing it RPR.

FIG. 6 illustrates a simplified diagram of an implementation of the invention during a data push to the storage and sharing device according to the invention.

The connected object 4, for example a thermometer using the LoRa communication protocol, implements an OR_TR transmission which sends data in particular in the form of a p (do) reading, for example per frame, through a local network, such as LoRaWAN, to a gateway using the same communication protocol, a gateway, also called gateway, LoRa. This gateway includes a receiving antenna radio transmissions according to the LoRa standard. The gateway implements in particular a demodulation of the received data and encapsulates them (in our example, encapsulates the frame) in a request according to an Internet protocol, in particular an http request. Thus, the object is connected to the Internet network. The gateway sends the encapsulated data in an Internet request dcd_req (p) to a mediation device 3. The mediation device 3 is, in particular, a network server using the same communication protocol as the connected object 4, for example a server LoRa network. The mediation device 3 performs a DCD decoding of the data received in the Internet request dcd_req (p). This DCD decoding makes it possible in particular to identify the connected object, possibly an identifier of the received data and the value of the received data, for example T ° = 22 ° C. Then, the mediation device 3 makes a PSH transmission of the received data to a storage and sharing device 2. This PSH transmission is in particular carried out in "push" mode, that is to say automatically (without prior reception of a request for data). Thus, the mediation device 3 sends the data do, in our example, the statement, from the connected object 4 to a loading interface 20 of the storage device and sharing adapted to the communication protocol of the connected object, in the LoRa protocol, especially via a consultation address also called "Callback URL".

Following this notification of the storage device and the data do of the object 4, the loading interface 20 carries out a loading of the data and deposits w (d03E) the data in the storage and sharing device 2. In particular, the data are assigned relative to the connected object from which they come: for this, the loading interface performs, for example, a creation of a set E_CREA in the storage and sharing device assigned to the object in which the data are entered. Thus, the database of the storage and sharing device 2 also called media server loT (for "Internet of objects", that is to say objects connected to the Internet) is updated by the loading interface 20.

Optionally, the loading interface associates a name with the identifier of the object, such as "salon thermostat" which will be associated with the set assigned to the object in the database. This technique makes it possible to aggregate the data of connected objects of various manufacturers and allows a user to use standard terminals, in particular by means of standard application, for example using U PnP, DLNA protocols or of equivalent standard in term architecture, to access it. The invention also relates to a support. The information carrier may be any entity or device capable of storing at least one of the programs. For example, the medium may include storage means, such as a ROM, for example a CD ROM or a microelectronic circuit ROM or a magnetic recording means, for example a diskette or a hard disk.

On the other hand, the information medium can be a transmissible medium such as an electrical or optical signal that can be conveyed via an electrical or optical cable, by radio or by other means. The program according to the invention may in particular be downloaded to a network, particularly of the Internet type. Alternatively, the information carrier may be an integrated circuit in which the program is incorporated, the circuit being adapted to execute or to be used in the execution of the method in question.

In another implementation, the invention is implemented by means of software and / or hardware components. In this context, the term module can correspond to a software component or a hardware component as well. A software component corresponds to one or more computer programs, one or more subroutines of a program, or more generally to any element of a program or software capable of implementing a function or a program. Function set according to the description below. A hardware component corresponds to any element of a hardware set (or hardware) capable of implementing a function or a set of functions.
