Description

TECHNICAL FIELD The invention relates to the field of the supply and provision of gas cylinders for primarily domestic or professional use. In particular, the invention relates to the management of the replacement of a empty gas cylinder of a user by a full bottle and the inventory management by the supplier.

STATE OF THE ART When a user has emptied his gas cylinder, he must exchange it for a full gas cylinder (deposit system). This exchange takes place at an equipped establishment which receives bottles of gas from a supplier. The storage compartment that housed a full bottle then receives an empty bottle. The accessibility to the compartment is done by a key provided by a staff of the establishment present on the site. Two difficulties arise. The first is the inability of the user to obtain a full gas bottle on closed days or at late hours, or, to a lesser extent, to obtain said bottle quickly if the staff is busy. The second is the supplier's supply management, which depends on the inventory status being updated by facility staff.

There is therefore a need for autonomy for the user and a need for inventory management improvement for the gas supplier.

DETAILED DESCRIPTION As previously mentioned, a provisioning device 1 allows a user to withdraw a full gas cylinder 2a and to return an empty gas cylinder 2b (called deposit). With reference to FIGS. 1 to 9, a device 1 for providing a gas bottle according to the invention comprises: A storage compartment C with closure means 3, said compartment C being able to receive a bottle of 2a full gas or 2b empty, - 4 locking means, allowing the opening and secure closure of the storage compartment C with the closing means 3, and comprising an electronic chip 41, - A source of power supply 5, - A motorization system 7.

Advantageously, a sensor 9 is provided to detect the presence or absence of a bottle 2a, 2b. It will be detailed later.

The locking means 4 are motorized by the motorization system 7 and powered by the power source 5. The unlocking is done using an electronic key 6 which is stored on an electronic device 61 when the latter is at a configurable distance from the electronic chip 41.

The allocation of the electronic key 6 is done for a given chip 41. More details will be given later. In a largely preferential embodiment, the electronic device 61 is of the type ordiphone, mobile terminal, smart phone (or "smartphone" in English terminology). For the remainder of the description, a mobile terminal 62 will be used for simplicity. Typically, with reference to FIG. 2, a complete plant I comprises a plurality of side-by-side and / or one-to-one devices 1, similar to the traditional storage compartments which can be found in equipped establishments (such as service stations). As illustrations, the dimensions of such an installation I are 1570x1960x750mm, for 130kg.

The storage compartment C is generally a metal rack with a jamb 33 and the closure means 3 comprise a chain or door mounted on hinges. Any design that makes it possible to prevent or allow withdrawal of a bottle 2a, 2b is suitable.

The electronic chip 41 comprises a radio transmitter 411, advantageously according to the Bluetooth standard that also manages most mobile terminals including the mobile terminal 62 used. The transmitter 411 thus makes it possible to establish a contact at a parameterizable distance, typically between 2m and 20m. This technology is complementary to other radio technologies that can be used by the mobile terminals 62 or the electronic device 61. The electronic chip 41 also includes a processor 412 for processing the data and a memory 413 for storing the data (FIG. 3). Each chip 41 of the complete installation I has its own identifier. The electronic chip 41 can exchange with the mobile terminal 62 information such as an electronic key verification 6, the availability status, an incident history, and so on.

To simplify the device 1 as far as possible, the electronic chip 41 is powered by the power source 5. Alternatively, a complementary power supply system can be provided. A standby controller may also be provided to put electronic components in standby during off-peak hours (at night, for example). The Motorization System 7 The motorization system 7 comprises a motor 71 driven by the processor 412. An interface module 72 may be necessary to convert the data. An encoder 73 is also advantageously provided, so as to be able to measure a state of the locking means 4, such as closed / open / closed. The encoder is for example of the electromagnetic or rotary type. An electronic switch (not shown) disables encoder 73 to limit power consumption.

For the device to operate, it must be powered by the power source 5. This can simply constitute a connection to the electricity supply network. In preferred embodiments providing the device 1 with a certain autonomy with respect to external contingencies or with respect to the installation locations, the power source 5 is integrated in the device 1. In a first embodiment preferred embodiment, the power source 5 is a solar panel 52, coupled to a battery 53 for storing energy (FIG. 3), with a converter module 54. The dimensions of the solar panel 52, as a illustrations, are 40x40 mm, with a capacity of 1.2V / 100 mA. This embodiment does not require any intervention of an operator. In a second embodiment, the power source 5 is a stack 51, 3.6V cell type 50x26mm. This provides sufficient autonomy for its periodic replacement by an operator does not pose major difficulty, for example, a refilling of full gas cylinders 2a.

Locking means 4 The locking means 4 make it possible to lock or unlock the closure means 3. They are motorized by the motorization system 7 which allows the unlocking of said means 4 when the electronic chip 41 recognizes the electronic key 6.

For the locking means 4, any automated lock system may be suitable. There may be mentioned two examples of particular preferred, non-limiting architecture.

In a preferred embodiment (FIG. 4), the locking means 4 comprise a hook 42 rotatable about an axis. This hook 42 comes into engagement with a chain 31 of the closure means 3 and thus closes the compartment C. When the device is opened, the hook 42 rotates and releases the link 31 which escapes locking means 4 under its own weight, by gravity. On the other hand, to facilitate closing and not having to perform any other manipulation than that of inserting the link 31, the hook 42 may comprise a protrusion 421. This protrusion 421 is adapted to rotate the hook 42 when the locking means 3. The encoder 73 which detects the rotation and which transmits the information to the processor 412, the locking means 4 is then activated to lock the closure means 3.

In particular, the position of the protrusion 421 may make it possible to detect a "closing" rotation, that is to say in the same direction of rotation as the hook 42 to lock the compartment C. Alternatively, one can simply have a hook 42 with a shape adapted for a single insertion which mechanically triggers locking by means of a spring or other biasing element. In this way, by inserting the link 31, the hook 42 is lifted which engages subsequently in the link 31. This solution is purely mechanical for closing.

The adapted shape is typically a convex portion on which the link 31 slides when inserted.

The user does not have his mobile terminal by hand when removing the bottle 2a: the closure must be mechanical or driven by a mechanical action.

The motor 71 of the motorization system 7 and the hook 42, as well as the encoder 73 are fixed in a lock cylinder 43 which solidarises the assembly to a housing 44 fixed on the doorframe 33 of the storage compartment C (FIG. ). A circlip 45 is provided on the motor 71 to be held in the cylinder 43.

In a normal operating regime, the motorization system 7 operates about four times at most (two locks and two unlockings, for the user and the provider operator) per day.

The information relating to the state of the locking means 4 or to the state of the motorization system is advantageously transmitted to the electronic chip 61 which can communicate them to the mobile terminal 62. Electronic key 6 As mentioned above, the electronic key 6 is stored on an electronic device 61, preferably a mobile terminal 62. The mobile terminal 62 and the electronic chip 41 exchange information and the electronic key is recognized by the electronic chip 41, which allows to trigger the unlocking of the means of 4. The recognition is done when the electronic key 6 is close to the electronic chip 41. The maximum distance depends on the characteristics of the components of the device 1. It can be of the order of ten meters. It is preferable that it be superior to the meter, for reasons which we will explain later. An electronic key 6 assigned to a mobile phone 62 can unlock only one compartment C.

On the other hand, the mobile terminal 62 can exchange information with all the electronic chips 41 of a plurality of devices 1 located nearby.

The mobile terminal 62 has access to a server 8 via a connection network 81, of Internet type (WIFI, GSM, GPRS, EDGE, UMTS, LTE ...) (Figure 6). It is not necessary for the mobile terminal 62 to have such a connection at all times. Indeed, it can store the data and communicate thereafter to the server 8. It is not necessary for the chip 41 to communicate directly with the server 8, which simplifies the installation and to lower costs.

This electronic key 6 is generated and downloaded from the server 8 on the mobile terminal 62, for example during the purchase of the bottle or any other event provided by the server 8, through the connection network 81. This download is made preferably before going to recover the full bottle 2a, so as to be sure of having a connection to the network 81 (when arriving at the depot, the user can not be sure of having a network coverage allowing him to talk with the server 8). Thus, once the electronic key 6 downloaded, it will be able, even without access to the server 8, easily identify the device 1 corresponding to open approaching.

Server 8 is managed by the gas supplier or a proxy. The connection to the server 8 thus allows in particular the creation of the electronic key 6 which will be recognized by the electronic chip 41 of a device 1 which houses, for example, a full bottle 2a.

After sending to the server 8 by the user of an electronic key recovery request (after a payment for example), the server 8 studies in its database which compartment C to assign to the request of the user. It responds to the request by an allocation to the mobile terminal 62 of said user of an electronic key 6 corresponding to said compartment C and its associated device 1. This electronic key 62 is then downloaded to the mobile terminal 62. following characters: 5 - Assignment for single use: that is to say that the electronic key 6 can unlock the locking means 3 only once, and if necessary, lock them once, Assignment on a limited time: the electronic key is valid for a short time because it would be easy and inexpensive for a malicious third party to buy all the lockers and never come to withdraw the full bottle 2a. The identity of the user is assumed to be known for obtaining a key 6.

Thanks to the device 1 which replaces the traditional key-lock system, the user can withdraw a full bottle 2a at any time of the day without the intervention of a dedicated staff. Nevertheless, for the allocation of an electronic key 6 designating a compartment C with a full bottle 2a and not an empty bottle 2b, and so that the supplier can know when he has to refill the devices 1, it is advantageous to equip with stock control means.

Such means make it possible to further improve the autonomisation of the device 1 and to make it operational for the users at any time. The sensor 9 As mentioned above, a sensor 9 is provided in the device 1 (see FIG. 3). To make it invisible to the user, it is preferably arranged in the jamb 33 of compartment C.

The sensor 9 is able to identify the presence or absence of a bottle, to find out whether the user has put back in place the empty bottle 2b after having recovered the full bottle 2a. Complementarily, it can possibly identify whether the bottle in place in the compartment is full 2a or empty 2b. In a preferred embodiment, the sensor 9 is an ultrasonic sensor that can identify the sonar-type bottle. The ultrasonic sensor operates from 10 cm to 30 cm, which allows freedom of positioning of both the sensor 9 and the bottle 2a, 2b in the compartment C. Alternatively, the sensor 9 is a weighing sensor, which evaluates the weight of the sensor. the bottle 2a, 2b and allows to know the filling state 15 of the bottle. The information provided by the sensor 9 relates to inventory data. These data are transmitted to the electronic chip 41, with wire or wireless, which stores them in its memory 413. Typically, a binary variable relative to the bottle is defined: bottle_state = 1 for full and bottle_state = 0 for empty. Each device 1 is associated with a variable bottle_state. In this way, when a plurality of devices 1 is installed, there are a plurality of bottle state variables (FIG. 7). An electronic switch can disable the sensor 9 to save energy.

Inventory Management There are several embodiments of the inventory management method.

In a first embodiment, the management is done without the use of the sensor 9. Indeed, the server 8 can know the status of the inventory simply by analyzing the electronic key request flows 6. For example, it can be defined that at the time of the allocation of an electronic key 6, the stock falls by one unit. Alternatively, such stock management can be defined when the server 8 receives from the mobile terminal 62 the data relating to the opening, or the closure of the locking means 4, or again relating to the state of the motorization system 7 .

In a first preferred mode, the mobile terminal 62 of a user who comes to retrieve a bottle 2a retrieves all the data from all the electronic chips 41 of all the devices 1 present in the vicinity. This is why a distance greater than 15 meters for the exchanges between the mobile terminal 62 and the electronic chips 41 is preferable. Each lock emits at regular intervals (for example every second) its identifier and its stock. In this way a mobile terminal 62 on approach scans all the locks to find the one assigned to it. During the scan step, the mobile terminal 62 retrieves the stock and the identifier of each device 1. After recovery, the mobile terminal 62 has all the data 25 relating to the stock status of all the devices 1 This data is then transmitted to the server 8 by the communication network 81, as soon as the mobile terminal 62 obtains an internet connection. On the other hand, the transmission of the electronic key 6 to the electronic chip 41 requires a connection, in particular Bluetooth. Thus, each time a user uses a device 1 (which causes a change in inventory), the supplier is kept informed 3032547 15 of the overall state of the stock. Such a method makes it possible to limit the errors, since if a connection is defective, the stock will be completely checked as the next user passes.

Alternatively, the mobile terminal 62 can recover only the data of the chip 41 of the device 1 concerned. The server 8 compiles the data from each of the mobile terminals 62 which participate in removing a bottle 2a and establishes the stock.

Standard inventory management methods are implemented at the server 8. As soon as the ratio of the number of full bottles 2a to the number of total bottles 2a, 2b is below a certain threshold, or when the number of full bottles 2a is less than at a certain threshold, a reorder decision is triggered. The recovery of stock data makes it possible to anticipate the behavior of users and to anticipate stock-outs. In particular, the allocation of an electronic key 6 to a user is done by means of the data relating to the stock on the server 8. Indeed, it is necessary to make available to the user a device 1 comprising a bottle full 2a. During the request for creation of electronic key 6, the server 8 analyzes said stock data and allocates a key 6 accordingly.

A graphical interface is provided on the mobile terminal 62 to display information essential to the smooth operation. In particular, an application is installed to enable operations.

A button to activate the unlocking is particularly present on the interface. The order of the steps is explained (see the procedure below) on the interface.

The exchanges with the server 8 are carried out automatically once the withdrawal operations have been completed, in order to limit the role of the user to the maximum.

5 Error handling Control protocols (transmission failure, corrupted data, impossible connection) make it easy to make the actual data transmission more reliable.

Here is a non-exhaustive list of the main checks that can be made: - During exchanges between the mobile terminal 62 and the server 8: o Compatibility of the mobile terminal 62, with sending a notification by the server 8, for example if the terminal 15 mobile can not exchange data with the electronic chip 41. In this case, the user can not perform an electronic key assignment request 6, o No connection to the server 8 to make a request for allocation of the electronic key 6. electronic key 6, 20 o Verification of the data relating to the allocated device (assigned key and identifier of the device), - During exchanges with the electronic chip 41: o Notification for the activation of Bluetooth, o In case of non-detection of an electronic chip 41, 25 notification to induce restarting the mobile terminal 62, o In the event of failure of the connection with the electronic chip 41, notification to retry the connection, o In the case of a false electronic key 41, put into contact with a helpdesk, 30 o In the case of a non-functional locking system 4 (faulty motorisation, etc.), detected by the encoder 73 for example, put into contact with a help desk.

In addition, warning systems are implemented for the electronic key 6, via the sensor 9 and the chip 41, a notification is sent to the mobile terminal 62 as soon as: - The full bottle 2a is removed, 5 - The bottle vacuum 2b (the setpoint) is set up, - The encoder detects a closing rotation when the closing means 3 are coupled with the locking means 4, - the locking means 4 are effectively locked.

These notifications are then transmitted to the server 8. Finally, the device 1 is designed to withstand climatic aging and salt spray (EN ISO 9227 standard) as well as 15 ATEX environments ("Explosive Atmosphere", resulting from directives European). Indeed, a bottle of uncapped gas, user return, can generate a zone 2 according to the ATEX standard in a perimeter of 1m, if the valve has not been previously properly closed 20 In particular the case 44 is in impact and scratch resistant aluminum and the various elements have undergone anodisation. The joints of the housing 44 are silicone to seal the housing. Finally, all the electronics (chip, electronic circuit, etc.) of the housing 44 are cast in silicone, with the exception of the battery 53.

The operating temperatures are between -20 and + 50 ° C. For this purpose, insulation, joints and materials are selected according to precise specifications.

Thanks to the embodiments of the invention, the already existing storage compartments C can be reused. The adaptations (motorization of the locking means, sensor, chip, etc.) do not require complex or expensive arrangements and have been designed to integrate as simply as possible. One method (FIGS. 8, 9a to 9e) is associated with the device 1. In the following description, the electronic key 6 is associated with a mobile terminal 62 having a connection to the communication network 81, of the internet type. In a first step E0, the user sends an electronic key recovery request 6 to the server 8. This creation request is issued from a payment or the entry of a purchase code for example. Several preliminary steps may be included, such as the connection to a user profile and / or the updating of the catalog by the server 8 in the mobile terminal 62. Then, in a step E1, the server analyzes the stock data and assigns a In practice, the request or delivery of the key may be subject to validation by a banking organization, for example. Subsequently, in a step E2 (Figures 8, 9a), the user goes to the site of provision of gas cylinders. Either it looks for the references of the compartment C corresponding to that of the key 6, or the mobile terminal 62 indicates to it by various means (notifications, audible alerts, etc.) when it is in the vicinity of said compartment C, via a recognition of the chip 41. In one embodiment, this step is broken down into substeps: E21: the mobile terminal 62 requests to connect to the electronic chip 41, E22: the electronic chip 41 sends an encryption key , E23: the mobile terminal 62 codes the electronic key 6 with the encryption key and sends it to said chip 41, - E24: the electronic chip 41 compares its own key with that received in the previous step, - E25: the chip 41 resets the electronic key 6 so that it can no longer serve. Step E3 consists of the withdrawal as such.

The user, in a step E31 (FIGS. 8, 9b), activates the unlocking of the compartment C and the compartment C becomes accessible. An opening notification is preferably sent to the mobile terminal 62.

In a step E32 (FIGS. 8, 9c), the user removes the full bottle 2a. A bottle withdrawal notification, generated using the sensor 9, is preferably sent to the mobile terminal 62. In a step E33 (FIGS. 8, 9d), the user sets up the empty bottle 2b. A bottle delivery notification, generated with the aid of the sensor 9, is preferably sent to the mobile terminal 62. In a step E34 (FIGS. 8, 9e), the user locks the compartment C with the aid of the locking means 4. The embodiments of the locking have been previously described. This step can be distinguished in three sub-steps: - E341: the user begins to insert the link 31, - E342: the encoder 73 detects a rotation of the hook 42, - E343: the locking means 4 are activated and lock the bin. If step E33 is not performed, an alert is sent to the user and / or server 8 in a step E '.

In a step E4, the electronic chip 41 retrieves the stock information from the other devices. This step E4 is preferably performed during step E2. Indeed, when the user scans the devices, the electronic chips 41 can exchange their inventory information with the mobile terminal 62. In the previously described steps, the mobile terminal 62 can recover as the states of the means 10 In a step E5, the data relating to the stock is transmitted by the mobile terminal to the server 8 as soon as a connection with the server 8 is possible. This data is established by means of the information from the locking means 4 and / or the motorization system 7, and / or the data of the sensors 9. During this step, the other data acquired by the notifications by the mobile terminal 62 are transferred also to the server 8, to store the management histories and possible complications that may have occurred. In a step E6, the server 8 analyzes said data and makes a decision on the replenishment according to the thresholds presented above. This step E6 can be performed without the step E5 (and therefore without the data from the mobile terminal 62), simply by using the electronic key request data 6 and / or allocation of said key.
