[0057] These and other features and advantages of the present invention will become clearer from the following description of some exemplary embodiments illustrated in the accompanying drawings in which:

[0062] FIG. 5 illustrates a view of a possible embodiment of the basin element belonging to the system object of the present invention;

[0063] FIGS. 6a to 6f illustrate the various management steps of the drone belonging to the system object of the present invention.

[0064] It is specified that the figures attached to the present patent application show only some possible embodiments of the drone management system object of the present invention, to better understand its described advantages and features.

[0065] Such embodiments are therefore to be understood for purely illustrative and non-limiting purposes of the inventive concept of the present invention, i.e., to provide a drone management system which allows to obtain an efficient resupply of the containers transported by the drones themselves, without necessarily requiring the landing of the drones.

[0066] With particular reference to FIGS. 1a and 1b, two perspective views of a possible embodiment of the system object of the present invention are illustrated.

[0067] The system comprises at least one drone 1 and a logistic support unit 2 of said drone 1.

[0068] The logistic support unit 2 in this case is illustrated as a truck, which has a trailer container inside from which it is possible to transport one or more drones, tanks for the resupply of the material to be loaded on the drone containers as well as perform all the necessary maintenance to the drones.

[0069] The logistic support unit can also comprise a plurality of trucks, also aimed at providing different services.

[0070] Especially in firefighting operations, a logistic support unit which can be moved on wheels is advantageous, as it can transport drones close to the fire and then have them take off, so as to reduce the flight time.

[0071] In particular, the logistic support unit allows the resupply of the drones.

[0072] In fact, the drone 1 comprises at least one container 3 adapted to contain service material, such as a firefighting liquid.

[0073] The logistic support unit 2 comprises a resupply area which comprises resupply means of the container 3, in which the drone 1 positions said container 3 so that it can be filled with at least service material.

[0074] The resupply means comprise position locking means of the container 3, dispensing means communicating with a tank and a dispensing mouth adapted to communicate with the container 3.

[0075] Furthermore, according to the variant illustrated in the figures, the resupply area comprises a basin element 4, the walls of which converge towards said resupply means.

[0076] The drone 1 thus makes several trips, in which it resupplies the container 3, which, in addition to an inlet mouth of the service material, comprises expulsion means of said service material.

[0077] FIG. 3 illustrates an exemplary diagram, in which the drone 1 releases a service material, for example the extinguishing liquid 5 on the fire 6.

[0078] The scenario of FIG. 3 is obviously replicable for fleets of drones 1, as illustrated in FIG. 6f.

[0079] With particular reference to FIGS. 1a to 3, the drone 1 envisages that the container 3 is fixed through connection cables 31, which confer an oscillation of the container 3 with respect to the drone 1, in a manner entirely similar to the bucket used by helicopters during firefighting operations.

[0080] The container 3 can obviously comprise several separate compartments, preferably each with an inlet mouth thereof so as to transport different liquids or service materials.

[0081] Furthermore, the container 3 can have connectors for the electrical connection to and from the logistic support unit 2 and/or to or from the drone 1.

[0082] Such connectors can be used for the transfer of information and/or to operate remote commands and automations on the container 3.

[0083] The drone 1 can be made according to any manner known in the state of the art, and comprises propulsion propellers powered by an energy source.

[0084] Preferably, according to the variant illustrated in the figures, such propulsion propellers are driven by combustion propulsion means, which thus require fuel.

[0085] The fuel is contained inside the container 3, which has a connecting tube 13, FIGS. 2 and 3, to allow the fuel to reach the propulsion means included inside the drone body 1.

[0086] To obtain such a configuration, the container 3, of which a possible embodiment is illustrated in FIGS. 4a to 4c, comprises a first compartment 32 adapted to contain the extinguishing liquid and a second compartment 33 adapted to contain the fuel and in communication with the drone 1 through the tube 13.

[0087] Each compartment has an inlet mouth thereof for the resupply of the compartment.

[0088] As can be seen in the figures, FIG. 4a illustrates a concept diagram of a section of the container 3, FIG. 4b illustrates a side view of a concept diagram of the container 3, and FIG. 4c illustrates a bottom view of a concept diagram of the container 3.

[0089] In particular, FIGS. 4b and 4c, the container 3 has an inlet mouth 34 for the first compartment 32, an inlet mouth 35 for the second compartment 33, a release hatch 36 for the material contained inside the first compartment 32 and mechanical locking means 37, the operation of which will be described later.

[0090] By virtue of such a configuration, the container 3, positioned at the resupply means can be filled simultaneously with both fuel in the second compartment 33, and with the extinguishing liquid in the first compartment 32.

[0091] It follows that the resupply means included on board the logistic support unit 2 must have a similar configuration, i.e., corresponding to that of the mouths of the container 3.

[0092] For this reason, FIG. 5 shows a concept diagram of a top view of the basin element 4, in which the container 3 is placed.

[0093] Subsequently, it will be described how the container 3 runs along the walls 41 of the basin element 4 to position itself precisely at the resupply point.

[0094] Once the container is correctly positioned inside the basin element 4, the mouth 34 of the first compartment 32 is coupled and in communication with the corresponding mouth 43, while the mouth 35 of the second compartment 33 is coupled and in communication with the corresponding mouth 44.

[0095] It is evident that the mouth 43 is connected to a tank containing the material to be inserted inside the first compartment 32, while the mouth 44 is connected to a tank containing the material, preferably fuel, to be inserted inside the second compartment 33.

[0096] Advantageously, pumping means are included for filling the first 32 and the second 33 compartments.

[0097] It is obviously possible to envisage that the logistic support unit rests on auxiliary units suitable for the transport of tanks, such as tankers, which are connected to the mouths 34 and 44 present on the logistic support unit.

[0098] It is possible to envisage that the mouths 43 and 44 are integrated into the centre of the basin element 4, or that the basin element 4 has a central hole capable of housing and connecting the mouths of the container 3 with the mouths 43 and 44.

[0099] In this second case, the mouths 43 and 44 are included inside the logistic support unit 2.

[0100] As illustrated in FIGS. 4c and 5, the container 3 and the basin element 4 include locking means for fixing the container 3 in position.

[0101] In particular, it is possible to include first locking means 36 which cooperate with corresponding second locking means 45.

[0102] The locking means can consist of a device for centring and orienting the container 3 with respect to the basin element 4 and by an electromagnetic opening/closing system for maintaining the connection between the logistic support unit 2 and the container 3 during the entire resupply step.

[0103] As anticipated, the presence of the basin element 4 facilitates the positioning of the container 3 for the resupply, as the container 3 slides along the walls 41 of the basin element 4 to reach the central point of the basin element 4 where the resupply occurs.

[0104] For this reason, the basin element 4 can be made in any of the manners known in the state of the art, as long as it has the walls 41 converging towards the resupply point.

[0105] The basin element 4 can for example include four side walls, joined in pairs through a junction element.

[0106] Therefore, all the side walls make a slide, in connection with the resupply point.

[0107] Preferably, the side walls have hinges at the base, so as to be able to oscillate, to close in the direction of the resupply point and decrease the dimensions of the logistic support unit 2.

[0108] It is evident that the side walls, in the closed condition, overlap at the roof of the truck.

[0109] Any joining elements withdraw in the closed condition of the side walls, so that they either fit between one wall and the other, or fall inside the thickness of the side walls or, alternatively, are made of a sufficiently yieldable material, so as to bend.

[0110] Regardless of the embodiment of the basin element 4, the container 3 slides along the walls 41 of such a basin element: the container 3 in the figures is illustrated is spherical in shape, however it is possible to envisage any shape.

[0111] For this reason, to facilitate the sliding of the container 3 on the walls 41, it is possible to envisage a system to facilitate the translation of the container 3 to the centre of the basin element 4 during its descent, such as metal beads arranged along the walls, which facilitate the descending direction and the sliding of the container 3.

[0112] The beads can be moved passively, i.e., by virtue of the sliding of the container on their surfaces, or they can be of an automated type.

[0113] FIGS. 6a to 6f illustrate a concept diagram of a possible operation of the system object of the present invention.

[0114] The figures show the case of only one drone, but it is clear how the steps illustrated can be repeated for fleets of drones, especially in firefighting missions, as illustrated in FIG. 6f.

[0115] When there is a need to carry out a specific mission, one or more logistic support units 2 are transported to near where the mission is to be carried out.

[0116] The logistic support units 2 deploy the drones transported therein, if any, and allow the take-off/landing of such drones. The drones can also be already present or transported by other means and can also land in different areas with respect to the logistic supports unit 2.

[0117] The drones begin to carry out the pre-arranged mission by performing shuttling for the transport of the service material between the logistic support unit 2 and the place where it is to be released.

[0118] Once the first transport has been carried out, the drones return to the logistic support unit 2 and ensure that the container 3 transported thereby can be reloaded.

[0119] Preferably, the descent of the container 3 towards the resupply point is always managed by the drone, which adjusts the flight altitude, detecting the distance with respect to the basin element 4.

[0120] The same container 3 can integrate dedicated sensors to detect the contact and the descending direction so as to inform the drone 1 of the lateral movement it must make to reach vertically above the centre of the basin element 4.

[0121] The drone 1, FIG. 6a, arrives at the basin element 4 and begins its descent so that the container 3 can enter inside the basin element 4, FIG. 6b.

[0122] Decreasing the height, the descent of the container 3 inside the funnel sees to the automatic centring and possible orientation, FIG. 6c.

[0123] Once the centre of the basin element has been reached, FIG. 6d, the container 3 is connected to the dispensers integrally by virtue of the locking/unlocking system 45 and 37 to ensure integral contact during the resupply step.

[0124] The resupply system is then activated which dispenses the liquids from the logistic support unit 2 to the container 3 up to an established filling.

[0125] The locking system is released by releasing the container 3, so that the drone 1 can again rise with respect to the logistic support unit 2, FIG. 6e.

[0126] With the container 3 full, the drone 1 can transport and release the contained extinguishing material, so as to subdue the fire, as illustrated in FIG. 6f, and then endlessly repeat the cycle 24 hours a day.

[0127] It is evident, from what has been described, that the filling automations of the container 3 can be controlled by a central control unit, remote or on board the logistic support unit 2, which monitors and controls the entire procedure.

[0128] Such a central control unit can also control the opening/closing of the side walls, as well as supervise the guidance of the drones 1.

[0129] It is also evident that a user can manually intervene, through remote controls, on the movement of the drones and on the procedure described.

[0130] While the invention is susceptible to various modifications and alternative constructions, some preferred embodiments have been shown in the drawings and described in detail.

[0131] It should be understood, however, that there is no intention of limiting the invention to the specific illustrated embodiment but, on the contrary, it aims to cover all the modifications, alternative constructions, and equivalents falling within the scope of the invention as defined in the claims.

[0132] The use of for example, etc., or refers to non-exclusive non-limiting alternatives, unless otherwise stated.

[0133] The use of includes means includes but not limited to, unless otherwise stated.
