The invention also relates to an industrial installation implementing a data acquisition device according to the invention, in particular an installation configured to distribute and / or consume one or more industrial fluids, as well as a method of data acquisition. provided by one or more sensors integrated in said installation. At present, the monitoring of the operation of industrial installations is carried out by means of data acquisition devices making it possible to collect, record and process the information coming from measurement sensors integrated in these installations. This is particularly the case for industrial installations configured to dispense and / or consume one or more industrial fluids, these installations generally using pressurized fluids, that is to say subjected to pressures greater than the pressure of the fluid. ambient atmosphere, which can also be subjected to cryogenic temperatures. The proper management of these fluids is therefore crucial to ensure the proper functioning of the facilities, but also to protect them from any industrial risk and to ensure the safety of operators working near these facilities. The management of an industrial installation involves the acquisition and monitoring of data relating to the installation and representative of its operation. In a manner known per se, the data acquisition devices comprise a large number of electronic components, such as amplifiers, samplers, acquisition cards, analog-digital converters. These components are used to record and process signals from sensors belonging to the installation. However, these electronic components are fragile and can quickly become obsolete due to technological developments. They must therefore be replaced regularly to ensure effective and reliable control of the operation of the installation.

In general, the data acquisition devices are connected directly to the industrial plant they are monitoring. Conventional devices are thus provided with a single interface that provides both a mechanical connection with the industrial installation and an electrical connection with the sensors of the installation. For such acquisition devices, the maintenance operations require a disconnection of the entire acquisition device of the industrial installation, then a reconnection of a new acquisition device, that is to say a device. device whose electronics have been replaced in whole or in part at the industrial installation. It is then necessary to reconfigure the electronics of the acquisition device which has been replaced, according to parameters specific to the industrial installation, such as the types of sensors integrated into the installation, the sensitivity of these sensors, alarm threshold values for the measurements made by these sensors.

However, this configuration or configuration is tricky and must be operated manually by qualified personnel. In addition to the fact that it is not always possible to use qualified personnel, parameter setting errors can still occur. This leads to the risk of errors in the measurement and processing of data relating to the industrial installation.

It is easy to understand that the same problems arise during the first implementation of a data acquisition device on an industrial installation, this first implementation also involving a parameterization of the device before putting it into operation. The problem to be solved is therefore to overcome all or some of the disadvantages mentioned above, notably by proposing a data acquisition device relating to an industrial installation whose implementation and maintenance are made more reliable and simpler than with conventional data acquisition devices.

Preferably, said installation is configured to distribute and / or consume at least one industrial fluid, said sensor being configured to measure at least one physical quantity representative of said at least one industrial fluid chosen from: temperature, pressure, flow rate.

According to an alternative embodiment, the installation according to the invention is configured to produce electricity, said sensor being configured to measure at least one physical quantity representative of the generated electricity chosen from: the intensity of the electric current, the electrical voltage, electrical energy, electrical resistance or electrical energy metering indexes.

According to another aspect, the invention also relates to a data acquisition method relating to an industrial installation according to the invention comprising the following steps: a) connection of the at least one sensor to the first connection interface of the connector, b) connecting the electronic logic to the second connection interface of the connector, c) transmitting to the electronic logic the data measured by the at least one sensor, via the first and the second connection interfaces, and acquiring said data by the electronic logic, characterized in that it further comprises, after the step of connecting the electronic logic to the second connection interface, a step of reading the memory by the reading element of the electronic logic, and a parameterizing step said electronic logic in response to the at least one parameterization information read from the memory.

In addition, the method according to the invention may comprise a step of transmitting to the connector at least one piece of information relating to the electronic logic by the data transmission member, via the second connection interface, and a recording step. said at least one information relating to the electronic logic in the memory of the connector.

Preferably, said method comprises a step of disconnecting the electronic logic from the second connection interface of the connector, said connector remaining integral with the industrial installation, a step of replacing the electronic logic with a new electronic logic, a step of connection of the new electronic logic to the second connection interface, a step of reading the connector memory by the reading device of the new electronic logic and a step of setting the new electronic logic in response to the at least one setting information read from the connector memory. The invention will now be better understood by means of the following detailed description with reference to the appended single FIG. 1 which schematizes an embodiment of a device according to the invention. FIG. 1 schematizes a device for acquiring data relating to an industrial installation equipped with several sensors 4. The invention is distinguished by the fact that the acquisition device comprises two distinct and separable parts: an electronic logic 1 configured to acquire data measured by the sensors 4, and a connector 2 adapted to be secured to the industrial installation. In fact, the connector 2 comprises a first connection interface 5 connectable removably to the sensors 4. Preferably, the first interface 5 allows an electrical connection of the connector 2 to the sensors 4. In addition, the connector 2 can be connected mechanically to the industrial installation.

The connector 2 further comprises a second connection interface 6 removably connectable to the electronic logic 1. Preferably, the second interface 6 is electrically and mechanically connectable to the electronic logic 1. The first and second connection interfaces 5, 6 are adapted to transmit to the electronic logic 1 the data measured by the sensors 4. This transmission is preferably performed by electrical conduction. For example, the connection interfaces 5, 6 may comprise at least one serial type digital link conveying a data exchange protocol, for example the MODBUS serial communication protocol. Said serial type link may comprise a UART transceiver (acronym for "Universal Asynchronous Receiver Transmitter"), an SPI data bus (acronym for "Serial Peripheral Interface") or I2C (acronym for "Inter Integrated Circuit"). ). Advantageously, the electronic logic 1 comprises the majority of the electronic components of the acquisition device, that is to say the components configured to acquire, record and / or process the signals transmitted by the sensors 4. The connector 2 comprises as for it a minimum of electronic components, including components such as electrical conductors, which are intended only to ensure the transmission of information from the sensors 4 of the installation to the electronic logic. The probability of failure or wear of the connector 2 is therefore very low. According to the invention, the connector 2 furthermore comprises a memory 7 configured to contain at least one parameterization information of the electronic logic 1 and the electronic logic 1 comprises a reading element 3 configured to read said memory 7 when the second interface of FIG. connection 6 is connected to the electronic logic 1. The electronic logic 1 is configured to parameterize in response to said at least one parameterization information read in the memory 7.

It is then understood that the device of the invention is implementation and maintenance simplified and reliable compared to conventional data acquisition devices. Indeed, when the device according to the invention is mounted on an industrial installation and it is necessary to maintain it, it is possible to disconnect only the electronic logic 1 of the second connection interface 6, the connector 2 remaining fixed on the installation. Once all or part of the electronic components of the electronic logic 1 has been replaced, a new electronic logic 1 is connected to the second connection interface 6 of the connector 2. When the connection between the electronic logic 1 and the second interface is established the reading element 3 reads the parameter information or information contained in the memory 7. The information is thus received by the new electronic logic 1, which is automatically set according to the value of the information stored in the memory 7 The operator implementing the new electronic logic therefore has no parameter operation to perform. This results in a reduction of the risk of parameterization errors and a greater simplicity of the operation of replacing the electronic logic 1. In addition, the parameterization, which may require depending on the type of installation the setting of a large number of parameters, is easier and faster since it is feasible in a single reading operation of the memory 7. The memory 7 is located in the connector 2 which is the most robust part of the acquisition device, since containing only a very small number of electronic components. The connector 2 is then only one element through which the electronic logic 1 is connected to the installation, and which requires little or no maintenance. Advantageously, said at least one parameterization information is chosen from: the type of sensor 4 integrated in the industrial installation, a type of physical quantity measured by the sensor 4, a predetermined threshold for said measured physical quantity, an acquisition rate data measured by the sensor 4, a type of digital processing applied to the data measured by the sensor 4, a measurement uncertainty, a measurement accuracy, a physical measurement unit.

The memory 7 can also be configured to furthermore contain at least one of: identification information of the industrial installation, information relating to said at least one sensor 4 integrated in said industrial installation, the location of the installation under form for example of latitude and longitude, a local location on plan. This information may for example consist of an identification number, the digital transcription of a bar code.

For example, the memory 7 may be an EEPROM type memory (acronym for "Electrically Erasable Programmable Read-Only Memory"), Flash or FRAM (acronym for "Ferroelectric Random Access Memory"). Preferably, the memory 7 is serially read. The reading element 3 may be of the microcontroller type advantageously using the same data transfer protocol as the reading interface of the memory 7, that is to say the second connection interface 6. According to a particular embodiment of FIG. embodiment, the reading member 3 is configured to cooperate by electrical conduction with the memory 7 when the second connection interface 6 is connected to the electronic logic 1. For example, the reading member 3 can access the memory 7 via serial, parallel or wireless access by radio transmission, more particularly by inductive coupling or close-field coupling.

According to an alternative embodiment, the memory 7 is located in a radio-tag, also known as the "RFID" (for "Radio-Frequency Identification"), "RFID-tags" or "RFID-transponders" systems. Such systems are described in particular in document US-A-2011/0152825. Among the "RFID" technologies, it will advantageously be possible to use the "NFC" (Near Field Communication) technology. The reading member 3 is then configured to cooperate by electromagnetic coupling with said radio-tag when the second connection interface 6 is connected to the electronic logic 1. In a manner known per se, the electromagnetic coupling allows a transmission of information without wire and without electrical contact between an emitter body of electromagnetic waves, here the reading member 3, and an electromagnetic wave receiving member, here the memory 7. This embodiment is therefore particularly advantageous when it is desired to eliminate the electrical contacts between the reading member 3 and the memory 7 in order to gain robustness and reliability. More specifically, the reading member 3 may comprise an inductive member such as a coil. Optionally, the electronic logic 1 may comprise a data transmission member 8 configured to transmit to the connector 2 at least one piece of information relating to the electronic logic 1, via the second connection interface 6. The memory 7 is then configured to record the said less information relating to the electronic logic transmitted by the data transmission member 8. The data transmission member 8 may be of the microcontroller type advantageously using a MODBUS serial data transmission protocol. It advantageously uses the same data transfer protocol as the reading interface of the memory 7. In particular, the data transmission device 8 may be of the UART (acronym for "Universal Asynchronous Receiver Transmitter") type, a bus SPI (acronym for "Serial Peripheral Interface") or I2C (acronym for "Inter Integrated Circuit"). Thus, it is possible to copy in the memory 7 information relating to the electronic logic 1 and its operating configuration, for example the identifiers of the equipment recipients of the information transmitted by the body 8, such as Internet address, telephone number , or the frequency of transmission, the number of attempts to send. This information will be used when replacing the electronic logic to set the new electronic logic 1. Advantageously, the recording of information transmitted by the transmission member 8 in the memory 7 can be performed periodically.

Optionally, when it is still desired to increase the level of reliability of the replacement of the electronic logic 1, the information relating to the electronic logic 1 can be copied in several copies in the memory 7. This makes it possible to overcome a possible loss of one or more blocks of information stored in the memory 7. The main application of an acquisition device of the invention is the monitoring and control of the operation of an industrial installation, particularly a consuming installation, i. e. using, or distributing an industrial fluid. This fluid may be in the gaseous state, liquid or diphasic (gas and liquid), in particular the fluid is pressurized, that is to say at a pressure greater than the pressure of the ambient atmosphere. For example, the installation may be a fuel cell consuming hydrogen gas and producing electrical energy. The device according to the invention can thus be integrated with such an industrial installation.

More specifically, the device is mounted on the installation so that the connector 2 is secured to said industrial installation and the electronic logic 1 is removably mounted on the connector 2. The installation comprises at least one sensor 4 configured to measure at least one physical quantity representative of a state of said installation, such as temperature, pressure, flow rate of the fluid. The pressure sensor may be of the piezoelectric or piezo-resistive type, or else a strain gauge type. The temperature sensor may comprise a platinum resistance probe, for example of the type ptl 00 or ptl 000 or a thermocouple. Furthermore, the device according to the invention can be integrated into an industrial installation for which said at least one physical quantity representative of a state of the installation is a physical quantity representative of the electricity produced by the installation. This electrical physical quantity may be chosen from: the intensity of the current, the voltage, the energy, the electrical resistance or the energy metering indexes produced by the installation. The device according to the invention is used to acquire data relating to the industrial installation and measured by the sensor or sensors 4. The transmission of these data to the electronic logic 1 takes place via the first and the second connection interfaces 5, 6. According to the invention, the integration of the acquisition device with the industrial installation involves firstly connecting the first interface 5 of the connector 2 to the sensor 4. This operation is in principle carried out only during the first implementation of the acquisition device on the installation of which we want to acquire the data. The electronic logic 1 is then connected to the second interface 6. Follows the step of parameterizing the electronic logic 1 in response to at least one parameterization information read in the memory 7 by the reading device 3. Preferably, at during the data acquisition process, at least one replacement of the electronic logic 1 is performed. To do this, after disconnection of the used or obsolete electronic logic, a new electronic logic 1 is connected to the second connection interface. 6. The reading element 3 of the new electronic logic 1 then reads the memory 7 so that the new electronic logic 1 is set in response to the parameterization information read in the memory 7. The data acquisition device according to the invention has a great simplicity of startup since the information necessary for its operation have been previously recorded in the memory 7. The parameterization is thus possible in a single reading operation of the memory 7. In addition, the operation of replacing the electronic logic 1 is transparent vis-à-vis the equipment recipients of the measured data, since the new logic electronic 1 is set in exactly the same way, i. e. according to the same setting information, as the old electronic logic 1.
