    The known industrial or medical gas supply systems use stations of pressurized gas bottle filling stations which make it possible to fill the empty bottles of the users. These empty bottles are collected empty from customers and brought back to customers via a relatively complex logistics. In particular, a known solution is to exchange empty bottles for full bottles. These refilling services are associated with different billing models that are more or less complex.

    According to another possible feature, the step of reception by the electronic unit of a reservation request for a use and information relating to a prepayment is performed via the internet and in particular via an application of a mobile phone. The invention may also relate to any alternative device or method comprising any combination of the above or below features. Other particularities and advantages will appear on reading the description below, made with reference to the single figure which represents a schematic and partial view illustrating the structure and operation of an example of a supply system according to the invention. .
    The pressurized gas supply system illustrated by way of example in FIG. 1 comprises a station for filling pressurized gas cylinders.
    This filling station conventionally comprises a source of pressurized gas and a filling circuit having a first end connected to the pressurized gas source and a second end comprising a filling ramp provided with a plurality of pressurized gas bottle filling stations. .
    In the non-limiting example shown, the source of gas under pressure comprises a tank 2 of liquefied fluid (cryogenic fluid) associated with an atmospheric heater 6 (heat exchanger for vaporizing the liquid). The liquid can be withdrawn from the tank 2 via a valve 3 and a pump 4 to the atmospheric heater 6. The pressurized gas produced can be stored in at least one buffer tank. The cryogenic pump 4 and atmospheric heater 5 may for example have a capacity of 100 Nm 3 / hour.
    Of course, the pressurized gas source may consist of any other suitable device such as, for example, tanks delivered and directly containing the gas at a high pressure, a system for producing pressurized gas ("PSA" adsorption at pressure variation ...) ...
    Downstream of the gaseous reservoir 6, the circuit 13 may comprise a sensor assembly (s) 7 (pressure, temperature, etc.) and a first isolation valve 8.
    Downstream, the circuit 13 preferably comprises a manual or controlled flow control valve 10.
    Still downstream, the circuit 13 comprises filling stations 14.
    Each filling station may comprise a hose at the end of which is an outlet connector 12 (or filling plug) intended to be removably connected to a filling connector of a bottle 14 of pressurized fluid.
    The filling circuit 13 preferably also comprises an isolation valve 15 (called "downstream isolation valve") at each filling station. Preferably, these downstream isolation valves 15 are valves controlled automatically electrically and / or pneumatically and / or hydraulically.
    The filling station further comprises an electronic control unit 9 of the valve or valves 8, 15 controlled to control their opening or closing. The electronic control unit 9, which integrates, for example, a PLC and / or a computer and / or a programmable microprocessor, comprises data storage, processing and data acquisition devices or circuits configured to establish and manage a schedule. use of filling stations.
    In particular, this electronic control unit 9 comprises a device for receiving data transmitted at a distance (antenna and / or wired input) and is configured to record a reservation of a use of a filling station in a determined time slot of said schedule. and information representative of a prepayment 16 of said use.
    In addition, the electronic control unit 9 can be configured to allow the opening of at least one of the valves 8, 15 controlled in said slot only after receiving reservation information that has been pre-paid. corresponding. That is, the filling station is configured to be driven semi-automatically. A user can, for example via a wireless telephone 18 ("smartphone") and via an application and a communication portal, reserve and pay a bottle filling service in a given open time slot of a schedule 19. For example, the user can, via an Internet or other network, make a dematerialized payment 16 which is transmitted to the electronic unit 9. The application can advantageously make it possible to choose the number of bottles to be filled at a given moment.
    The reservation schedule 19 can be made available online to inform the users about the filling slots and the availability of the filling ramps.
    This paid prepayment information is a necessary data and prior to the possibility of filling in said slot. This simplifies and secures the transaction between the filling station and the customer by avoiding complex exchanges and sources of complications.
    Thus, the refills can be anticipated and carried out by an intermediary who takes care of the collection of the empty bottles and the return of the filled bottles.
    In filling centers, users can bring their bottles at the established time and place them on the packaging ramp when the time slot begins, under the supervision of a station manager.
    In order to facilitate organization, a color coding system can allow the user to know where to place his bottles on the ramp and to find them easily. That is to say that the bottles can be attributed to a customer and it takes, after packaging (filling), the same bottles he has made.
    Throughout the filling process, from the entrance of users with their empty bottles in the station, to their exits, the person in charge of the station checks the technical and safety aspects (gas connections, launching of the filling recipes in case gas mixture ...). At the end of the conditioning phase, the person in charge can disconnect the filling connections and invite the users to take back their bottles.
    Of course, preferably the system is configured to handle any discrepancies between the reservations and the number of bottles actually made.
    If the bottles are entrusted to a user, a unique identifier can be assigned to the corresponding bottles (painted or glued for example). The traceability of the logistics is improved.
    For economic reasons, the flow control valve 10 instead of being of the automatic type, can be a manual valve. In the latter case, preferably an assistance to its manual control is proposed by the electronic unit 9, for example via a screen (to indicate in particular to the user whether the flow must be increased or decreased).
    Once the bottles 14 connected and the filling process activated, the filling station can have an automatic or semi-automatic operation.
    For example, a pressure measurement can be made in the ramp at the opening of the filling clamps after putting the overpressure conditioning ramp to a determined value to reach, at the end of verification, the target filling pressure of the bottle . This safety measure may be based on the measurement of a pressure drop observed on each bottle at the opening of the filling tongs.
    One method is to fill the bottles in a conventional manner but at a pressure lower than the filling pressure and then to close all the filling sockets. The upstream part of the ramp is then put under a pressure greater than the filling pressure of the bottles. The valves 8, 12 regulators are then closed to trap this overpressure between these valves and the bottles 14. The verification starts by opening each take one after the other. A pressure drop in the ramp is measured at each tap opening. It is the characteristic of these descending fronts that can make it possible to check the correct filling or to detect an anomaly.
    If all bottles are correctly filled, in this case the overpressure will be distributed in the bottles. At each opening of the valve 12 of a bottle, this overpressure will drop slightly by a value corresponding to the theory. This slight drop will be noted in reading and control via the electronic control unit 9.
    On the other hand, if one or more outlets were closed or another defect prevented the filling of bottles, one will not note any modification of the residual pressure of the ramp and the defect is thus detected.
    In the case where one or more bottles are not filled to the correct pressure, the opening of these bottles will note a drop in the overpressure of the ramp greater than that provided by the calculations. We will detect at this time the lack of filling for these bottles.
