    - 1 DESCRIPTION
    The present invention relates to the field of remote reading, that is to say the remote collection and centralization of measurement data provided by sensors, detectors or comparable means, individual, dispersed geographically and energetically autonomous.
    The invention relates more particularly to a method and a system for collecting and remote reading of measurement data supplied by such sensors.
    Currently, in the field of remote reading of domestic meters by radio transmission, the raw measurement data supplied by the sensor concerned are processed on site and processed by the latter or its associated radio module according to the available analysis means (software used by the microprocessor or the microcontroller of the sensor or of the radio module) and of the “trade” functions to be performed.
    Given the diversity of the “trade” functions desired by the operators or operators, and their evolution over the lifetime of the sensors, the electronic and computer means of each sensor / radio module assembly must be sufficiently sophisticated and complex to be able to provide sufficient and adaptive resources over time, as well as a bidirectional radio link or not (at least to allow the necessary scalability of software means).
    This results in major problems in managing local energy consumption and therefore in operating autonomy (need for repetitive maintenance, changing batteries, replacing the radio module, etc.), and transmission security (due to of its possible bidirectionality).
    In addition, given the nature of the data transmitted (results of local processing) and the development over time of the types of local processing carried out, the data collected over a significant period may not be homogeneous with each other, or even not allow access to certain information, data values, not taken into account or not considered during a previous operating period of the sensors.
    The question of energy autonomy is even more sensitive when the uplink transmission (from the sensor to the remote reading means
    -2fixed or mobile) is performed repetitively at regular intervals, thus accumulating significant energy expenditure for treatment and emission.
    This problematic with multiple aspects explained above arises in particular in the context of the measurement of consumption in individuals (gas, water, energy, ...) or permanent monitoring of one or more parameters of physical quantities or local physico-chemical.
    The object of the present invention is in particular to overcome at least some, preferably all of the drawbacks mentioned above.
    To this end, the subject of the invention is a method of collecting data supplied by measurement sensors, located locally and associated with radio frequency communication means, integrated into the respective sensors or forming remote modules, these sensors and / or these modules comprising means for storing and conditioning the readings, as well as an autonomous power source for said sensor and said communication means, method characterized in that it comprises at least the steps consisting:
    to take, at each sensor concerned, successive measurement data corresponding to time-stamped elementary measurement units of at least one physical or physicochemical quantity or parameter, supplied by said sensor, to store these raw measurement data in the storage means of said sensor or of said module, to transmit this data as it is, by radio frequency and in compressed form, this in a repetitive and conditional manner, each time after the expiration of a predetermined time interval and / or after reaching a predetermined amount of accumulated data, since the previous transmission, and collecting, storing and using the data transmitted by a plurality of sensors at a remote centralized processing installation.
    The invention will be better understood from the following description, which relates to preferred embodiments, given as
    -3 non-limiting examples, and explained with reference to the appended schematic drawings, in which:
    Figure 1 is a schematic and symbolic representation of an example of remote reading system for the implementation of the method according to Γ invention;
    FIGS. 2A to 2C schematically illustrate two alternative embodiments of a sensor / radio communication means assembly, respectively integrated (FIG. 2A) and non-integrated (FIGS. 2B and 2C), forming part of a system as shown in FIG. 1;
    FIG. 3 is an example of a chronogram of the raw measurement data (here in the form of time-stamped dots) recorded by a sensor, between two uplink transmission operations (messages or telegrams sent at times TE_, and TE by a radio module), in a context of remote reading of volume consumption (here the PAj package includes N timestamped wells);
    FIG. 4 is an example of the structure of a message sent by the radio module of a sensor as shown in FIGS. 2A, 2B and 2C, and FIG. 5 is a timing diagram illustrating the redundant transmission of the raw time-stamped measurement data packets according to a embodiment of the method according to the invention (shifting of packets according to a FIFO mode).
    The first object of the invention is a method of collecting data supplied by measurement sensors 1, located locally and associated with radio frequency communication means 2, integrated into the respective sensors 1 (and thus constituting a unitary assembly - FIG. 2A) or forming remote modules (Figures 2B and 2C).
    These sensors 1 and / or these modules 2 include means 3 for storing and conditioning the values recorded, this with a view to their transmission, as well as an autonomous power source 4 for said sensor 1 and said means 2 of communication.
    The means which this process can call upon for its implementation are illustrated, by way of examples, in FIGS. 1 to 5.
    According to the invention, this method consists at least: of reading, at each sensor 1 concerned, successive measurement data corresponding to elementary time-stamped measurement units PUi of at least one physical quantity or parameter or physico-chemical, supplied by said sensor 1,
    To store these raw measurement data PUi in the storage means 3 of said sensor 1 or of said module 2, to transmit these data PUi as they are, by radio frequency and in compressed form, this repeatedly and conditionally, each time after a predetermined time interval has elapsed and / or after reaching a predetermined amount of accumulated compressed raw measurement data PUi, since the previous transmission, and in collecting, storing and using the data transmitted by a plurality of sensors 1 to level of a remote centralized processing installation 8.
    Thanks to the invention, it is thus possible, at the reception site, to have information allowing a faithful and integral reconstruction of all the raw measurement data provided by the various sensors 1 and allowing unlimited flexibility for the of said data. We can therefore easily and centrally take into account the scalability of the "business" functions without impacting the operating mode, nor a fortiori the constitution of the assemblies [sensors 1 / communication means 2].
    The constitution of the sensor 1 can therefore be simpler and its operation safer, and the energy consumption of the sensor 1 / communication means 2 assembly is lower than the current embodiments using the data locally.
    Finally, the transmission implemented does not necessarily have to be bidirectional, except for example to want to control the instant of emission of a sensor 1.
    Those skilled in the art understand of course that the invention can be applied to the measurement and remote reading of a very wide variety of parameters and quantities: it suffices to be able to precisely date an elementary variation (measurable by the sensor) of this parameter or this quantity, in accordance with the resolution of the sensor 1 considered (the elementary time-stamped variation can correspond to the resolution of the sensor or possibly to a multiple of this resolution).
    When the quantity or parameter measured can also decrease, the raw measurement data PUi are elementary time-stamped and signed units of measurement (positive or negative units).
    In relation to an advantageous application of the invention, associated with the concept of consumption, it can be provided that the or one of the physical quantity (s) measured is relative to a circulating fluid, each raw time-stamped measurement data PUi corresponding to an elementary quantity of fluid measured by the sensor 1, this function of its measurement accuracy. The measured fluid can for example be gas, water, fuel or a chemical substance.
    Alternatively or cumulatively with the implementation variant mentioned above, the invention can also provide that the or one of the physico-chemical quantity (s) measured is chosen from the group formed by the temperature, pH, conductivity and pressure of a fluid passing through or contacted by the sensor 1 concerned.
    Furthermore, when alternatively or cumulatively, at least one parameter is measured, this parameter or one of these physical or physicochemical parameter (s) measured can be indicative of the quality and / or of the composition of a fluid passing through or contacted by the sensor 1 concerned, such as for example the turbidity, the presence of pollutants or the presence of solid and / or gaseous fraction (s).
    Of course, the quantities and parameters indicated above are only nonlimiting examples.
    According to a practical embodiment, particularly emerging from Figure 3, each raw measurement data consists of a timestamped well PUi.
    In order to allow the method according to the invention to adapt to changes in the evolution of the parameter or the measured quantity, while retaining a satisfactory refreshment of the instantaneous data available, the method advantageously consists in carrying out a new data transmission. , in the form of a message or telegram, as soon as at least one of the two conditions
    a) the flow of a predetermined time interval and
    b) of reaching a predetermined amount of accumulated compressed data, since the previous transmission, is filled.
    The application of the aforementioned condition b) may, for example, consist in verifying regularly, after a predetermined number of new raw data has been noted, the size of all of said new data in the compressed or compressed state.
    -6When this size is close to a critical size, for example the size of a packet fixed by the transmission protocol, a new transmission operation is performed (condition b) checked before condition a)), unless the time limit prefixed between two successive transmissions has not been reached first (condition a) checked before the condition
    b)).
    Thus, as illustrated diagrammatically in FIG. 1, the method preferably consists in transmitting by radio frequency, when at least one of the conditions is satisfied (they can exceptionally be fulfilled simultaneously), the raw measured and compressed measurement data of each sensor 1 concerned either to a fixed concentrator module 5, managing and interfacing a local network 6 of a plurality of sensors which are associated with it and of which it manages uplink transmissions at least, or directly to the processing installation 8, in particular depending on the radiofrequency transmission technology used, the performance of the communication means 2 of the different sensors 1 and / or the respective locations of the latter.
    As far as possible, a solution will be sought which does not require the use of concentrator modules 5, or else only for part of a local network 6 or only for certain local networks 6 in a geographical area 9.
    However, in certain application contexts, the use of concentrator modules 5 will be necessary to achieve sufficient transmission quality.
    More precisely, in relation to the implementation of concentrator modules 5, the method may consist, in terms of packaging, of compressing or compressing the stored raw measurement values and putting them in a format suitable for radiofrequency transmission, to be transmitted , when at least one of the conditions is satisfied, said compressed and formatted data to a fixed hub module 5 forming part of a wireless local area network 6, then to retransmit said compressed and formatted data, together with the compressed and formatted data of each other sensors 1 forming part of the same network 6, for example by means of an Internet link 10, to a remote processing installation 8, such as a computer center or the like, with a view to their centralized operation.
    -7 The concentrator modules 5, energy independent or supplied by lines, can be modules dedicated to this function or shared (they then also perform other functions).
    Possibly certain sensors 1 can, through their module 2, act as concentrator modules for surrounding sensors 1 provided with more limited or incompatible means of transmission in terms of consumption.
    Alternatively or cumulatively with respect to the transmission modes mentioned above, the method can also consist, for each sensor 1 concerned, of transmitting the compressed raw measurement data by radiofrequency, to a mobile radio remote reading unit 7, this after receiving a corresponding request from the latter or automatically at regular intervals (Figure 1).
    This mobile unit 7 can either store the recovered data over a time interval (for example a day) and then download them to a processing site 8, or retransmit them immediately and progressively to this site 8.
    The raw measurement data retrieved by the mobile unit 7 may not cover the entire period since the last visit of the unit. However, additional data, in particular basic information (for example alarms, a consumption index, etc.) can be transmitted simultaneously during each transmission from a given sensor 1 to the mobile unit 7.
    Provision may even be made, if necessary, to establish, during the proximal passage time of the mobile unit 7, a bidirectional communication with the sensor 1 concerned for the exchange of additional information or for carrying out a configuration or an updating. day of said sensor 1.
    As shown in FIGS. 4 and 5 by way of example, provision may be made for conditioning the compressed raw measurement data by formatting them in PAj packets whose size cannot exceed a predetermined maximum value, a new transmission being triggered each time that the accumulated data reach the size of a packet PAj, unless the predetermined time interval has elapsed before.
    In order to be able to guarantee reliable and complete recovery of the raw measurement data even in the event of poor quality of the radio link, the data transmission is carried out with redundancy,
    Advantageously multiple, for example at least triple, preferably at least fivefold.
    In accordance with a possible practical aspect of the invention shown in FIG. 5, the redundancy in the transmission can be achieved by repeated transmission of the same data packet PAj in several successive transmission operations, each transmission operation carrying at least on the last three, preferably at least on the last five, PAj packets formed (FIG. 5 illustrates a redundancy of 5).
    According to a variant of the invention, the compression of the raw data is carried out without loss.
    According to another variant of the invention, the compression of the raw data is carried out with a predetermined authorized loss level. When the user or operator favors energy saving and accepts a certain inaccuracy in the restoration and restitution of the initial measurement data (i.e. accepts a certain loss), the rate compression can then be increased, to the detriment of poorer accuracy during restitution on the reception side. It can be expected that this loss rate or the compression rate constitutes a programmable or adjustable parameter, determining or setting the compression mode.
    By way of illustrative and nonlimiting examples of data compression algorithms, it can be envisaged to implement, within the framework of the method according to the invention, differential coding (delta coding) associated with Huffman coding, coding by ranges (RLE coding) or, preferably, adaptable binary arithmetic coding (CAB AC coding).
    In addition, and also by way of illustrative and nonlimiting example, the protocol for transmitting the raw measurement data from the sensors or counters 1 considered can comply with standard EN 13757, advantageously to the part of standard EN 13757- 3 with regard to the transport layer, with the part of standard EN 13757-4 with regard to the physical layer, the connection and the format of the frames, and with the part with standard EN 13757-7 with regard to the security, preferably with application of mode 8.
    As illustrated in an exemplary manner in FIG. 4, provision may be made to transmit, with the packets PAj of raw data PUi,
    -9 also the identity I of the sensor 1 concerned and the absolute or accumulated value VA of the quantity or of the physical or physicochemical parameter measured by the sensor 1 concerned, this value VA being time-stamped or associated with one of the data of time-stamped elementary measurement PUi, for example a fluid counter index value.
    The method can also consist in reading and transmitting, with the packets PAj of raw data PUi, the value at a determined instant of at least one other physical or physico-chemical parameter PPC of the environment of the sensor 1 concerned or of the fluid measured by the latter, such as for example the conductivity of the fluid, the temperature of the fluid, the pH of the fluid, the pressure of the fluid, a parameter indicative of the quality and / or of the composition of the fluid and / or the temperature of the installation environment of the sensor 1.
    Finally, said method may also consist, at the level of the remote centralized processing installation 8 comprising adequate hardware and software means, to carry out, on the one hand, after decompression, an exploitation of said received raw measurement data, with a view to the reconstruction of the timing diagrams of the values associated with each of the sensors 1 and the execution of business functions and, on the other hand, a cumulative storage of said raw data, and possibly of the data resulting from the processing, coming from all the sensors 1 of the networks 6 connected to said installation 8 considered, and timing diagrams of the corresponding values, this over a significant time period.
    Thanks to the collection and storage of all the time-stamped and signed elementary measurement data (raw data) delivered by all the sensors 1 of or of a given network, the invention makes possible all types of evaluation, analysis, verification, monitoring and, more generally, useful and desired processing and exploitation, since basic individual raw information is available.
    Thus, in addition to the calculation of the consumption and the average flow at different levels (by sensor 1, by group of sensors 1 or in the network) the invention also makes it possible, in a centralized manner, to carry out a backflow detection, calculations underflow or overflow, search for fraud and leaks, recall of the entire consumption history, etc.
    The subject of the invention is also, as shown diagrammatically in FIG. 1, a system comprising, on the one hand,
    - 10 sensors 1 each comprising means 3 for at least temporary storage and conditioning of the raw measured values with a view to their transmission, or at least functionally associated with such means 3, and, on the other hand, at least one treatment installation 8 remote, such as a computer center, suitable and intended for recovering, storing and exploiting the raw data coming from the various sensors 1 of the geographic area 9 considered, as well as other areas covering a global territory associated with said installation 8.
    Each sensor 1 is associated with means 2 of radio frequency communication, integrated into the sensor 1 considered or forming a separate and remote module, and an autonomous supply means 4 for the sensor 1 and the aforementioned communication means 2 is provided.
    This system is suitable and intended for the implementation of the method described above and is characterized in that the means 3 for storage and processing of each sensor 1 or module 2 concerned comprise a microcontroller configured to perform data compression of raw time-stamped measurements and their packaging in a format suitable for radiofrequency transmission according to a determined protocol.
    When the sensor 1 does not form structurally, with the radio module 2, a unit or a unitary assembly (like that of FIG. 2A), several alternative constructions in two separate physical sub-assemblies are possible (these sub-assemblies being connected between them for example by a wired connection for communication and food), namely:
    - A first sub-assembly grouping together the sensor 1, the memory 3 (and the conditioning and processing means) and the cell or battery 4 and a second sub-assembly corresponding to the only radio module 2 (FIG. 2B);
    - A first sub-assembly reduced to the single sensor 1 and a second sub-assembly comprising the radio module 2, the memory 3 (and the conditioning and processing means) and the cell or battery 4 (FIG. 2C).
    The processing, packaging and storage means 3 are preferably grouped together on a circuit or in a microcontroller or the like and can also, if necessary, manage the radio module 2.
    - 11 In addition, said at least one installation 8 comprises hardware and software means and is configured to perform, on the one hand, after decompression, an exploitation of said received raw measurement data, with a view to reconstructing the timing diagrams of the associated values to each of the sensors 1 and the execution of business functions and, on the other hand, a cumulative storage of the raw data and possibly of the data resulting from the processing coming from all the sensors 1 of the connected networks 6, and from the corresponding profiles, this over a significant period of time.
    In addition, the aforementioned system may include, for the or each geographic area 9 in which the sensors 1 considered are installed, a fixed concentrator module 5 forming with the sensors 1 of the area 9 which is allocated to it a wireless local area network 6 of which it is the master and the sensors 1 the slaves, said fixed concentrator module 5 also being connected, for example by means of a link 10 via the Internet, to said at least one remote processing installation 8.
    This constructive option using concentrator modules 5 over at least part of a geographical area may be implemented when reliable direct transmission between sensors 1 and installation 8 is not possible, or when it requires too much high consumption of sensors 1.
    Advantageously, this system also comprises at least one mobile radio frequency remote-reading unit 7, for example mounted in a motor vehicle, suitable and intended to collect on the fly, during its passage near a sensor 1 considered, the data raw measurement, this after prior sending of a corresponding request from the mobile unit 7 to the sensor 1 considered, or automatically at regular intervals.
    The remarks made previously in connection with such a mobile remote reading method remain valid.
    Preferably, and in relation to one of the conditions for repeating transmissions, the storage means 3 of each sensor 1 form a buffer memory and are adapted and configured to store the content of several packets PAj of raw measurement data at the compressed state, the content or part of the content of this buffer memory being transmitted on each uplink transmission from the sensor 1 concerned, preferably in a redundant manner as indicated above.
    The information collected by each mobile unit 7 is transmitted, directly or not, to the installation 8 or management 11 of the owner and / or operator of the associated sensor network 1 (and of distribution), which also defines the business functions to implement at the level of said processing installation 8 (the resources and the stored data of which are made available to it).
    Of course, the invention is not limited to the embodiments described and shown in the accompanying drawings. Modifications remain possible, in particular from the point of view of the constitution of the various elements or by substitution of technical equivalents, without thereby departing from the scope of protection of the invention.
