Definitions
- the present invention relates to systems for transporting goods, in particular in an urban environment.
- a transport system comprising a micro-tunnel buried at a relatively great depth has been proposed.
- Such a system is intended to ensure the transport of a high daily tonnage of goods and must be perfectly reliable, because any stoppage of it would pose the problem of the accumulation of undistributed goods.
- the reliability of the system is all the more critical as the depth of the tunnel is likely to make any repair or emergency response more difficult, compared to a transport system located on the surface.
- the invention aims to further improve freight transport systems, in order to address the issue of the distribution of goods in the heart of cities, and in particular to ensure the proper management of the flow of goods.
- an automated system for transporting goods comprising:
- the shuttles can each be loaded with at least one merchandise and / or at least one merchandise transport container, at least one degree of priority being assigned to at least one merchandise and / or at least one container,
- this infrastructure comprising stations for loading and / or unloading the shuttles, making it possible to load and / or unload the goods and / or the containers and to take charge of these goods and / or containers with surface vehicles,
- the shuttles to receive information relating to the remaining reception capacity of each loading and / or unloading station to receive goods and / or containers, the selection of loading stations and / or unloading where the shuttles are loaded and / or unloaded taking place automatically according to the remaining capacity of the stations, the final destination and the degree of priority of the goods (s) and / or containers transported by the shuttles.
- the invention makes it possible in particular to guarantee a good circulation of goods respecting the priorities imposed in their distribution.
- the automated goods transport system also has at least one of the following characteristics, and more preferably all of the following characteristics:
- each shuttle being arranged for:
- Each shuttle may have wheels, which may or may not be steered and equipped or not with tires. These wheels can be configured to allow the shuttles to move on rail tracks or not. These wheels can turn if necessary around non-parallel axes of rotation, for example to rest directly on a non-planar wall of a tunnel.
- Each shuttle can include at least one braking member.
- the motor means of each shuttle is configured to set the shuttle in motion, at least during one phase of its operation.

- This motor means may include at least one electric motor, which may be unique.
- the driving means comprises at least two driving wheels each provided with a motor. This can reduce the risk of the shuttle immobilizing in the event of a breakdown, reduce the size of the motors and simplify the transmission.
- each shuttle may include at least one energy storage means configured to supply energy to the shuttle, and in particular to its medium motor. This ensures at least partially, or even entirely, the energy autonomy of the shuttle.
- the storage means can include one or more accumulators.

- each shuttle has at least one generating means for supplying energy to the storage means.
- the shuttle may include at least one wheel driven by the speed differential between the shuttle and the infrastructure and configured to drive an alternator in order to recharge the storage means.
- the shuttle can be coupled during at least one phase of operation to a mobile drive cable within the infrastructure so as to be driven over at least part of the infrastructure by the drive cable, and the wheel abovementioned is driven in rotation in order to reload the storage means of the shuttle.
- the shuttle can disconnect from the drive cable and move by using its motor means powered by the storage means.
- the work provided by the drive cable is used to store energy within the storage means with a view to returning it to the motor means of the shuttle at times when the shuttle needs to move autonomously.
- the autonomy conferred on the shuttle outside the sections equipped with drive cables allows the shuttle in particular to easily manage the bends in the journey, without having to have complex mechanical systems to ensure angular deflection of the drive cable. in the bends. This can simplify and reduce the cost of the shuttle traffic infrastructure.
- the traffic infrastructure can include at least one electrified track, arranged for example along at least a portion of a section of a traffic lane, to supply energy to the shuttle, in particular to supply its means. motor and / or recharge its energy storage means.
- the infrastructure can also be devoid of such a track, which simplifies its construction and increases its reliability.
- the shuttles can have a space for receiving one or more loading units such as containers or palletized goods, and preferably two, four, six or eight loading units arranged side by side.
- This reception space can be sized to receive four, six or eight containers arranged in two rows of two, three or four containers, each container being adapted to receive a standard pallet, in particular a pallet, a half-pallet or a quarter-pallet.
- ISO type also called American or universal
- EPAL / EUR also called European
- CP or VMF As a variant, the reception space can be adapted to receive two, three or four double containers, each double container being adapted to receive two standard pallets arranged side by side within the double container.
- the containers can be detachably attached to the reception area.
- the containers can have a cross section of any general shape, circular or not, with a flat, polygonal, in particular square.
- Each shuttle may have a roof that extends above the loading unit (s), and front and rear bulkheads on which the roof rests and between which the loading unit (s) are disposed.
- the shuttles are without front and rear partitions.
- Each shuttle can be opened on the sides.
- the automated transport system may include at least one shuttle equipped to fight the fire, preferably entirely dedicated to this function.
- This shuttle may include at least one fire detector that is more sensitive than those possibly present on the other shuttles not dedicated to this function.
- This shuttle can also include a reservoir containing a product for extinguishing the fire, such as for example carbon dioxide, and a system for projecting this product, for example a robotic lance.
- This shuttle may include an infrared reflecting coating and one or more cameras or radar allowing vision in the presence of smoke.
- the dedicated fire-fighting shuttle (s) can run permanently on the infrastructure, at predefined intervals, or be parked in predefined locations along the infrastructure, and only be put into service in the event of of problem.
- each shuttle is preferably sufficiently powerful to allow it to push and / or tow at least one preceding or following shuttle, the motor means of which would be faulty, this troubleshooting being able to be carried out at a reduced speed.
- the automated transport system may include at least one shuttle equipped for the maintenance and / or troubleshooting of at least one other shuttle.
- This shuttle may have a more powerful motor means, making it possible to tow or push one or more shuttles at a relatively high speed.
- This shuttle can also be equipped with a system for diagnosing the failure and / or making up for it.
- each shuttle has at least one connector which can be coupled automatically to a corresponding connector of another shuttle or of the shuttle dedicated to the breakdown function, in order to facilitate the exchange of information, in particular by case of failure of the wireless connection, and / or to allow energy transfer between the shuttles, for example to supply electrically the motor means of the faulty shuttle.
- At least one unloaded shuttle can circulate within the infrastructure.
- This shuttle can be inserted between shuttles traveling with a load.
- a shuttle without loading can be inserted in a regular manner all the n loaded shuttles which follow one another, with n integer greater than or equal to 2.
- This shuttle without loading can play the role of communication relay as explained below, or can be used to come to the aid of a faulty loaded shuttle.
- Each shuttle preferably has an identifier, which can be read by the other shuttles and by the infrastructure.
- Each shuttle can include at least one optical identifier, for example in the form of a bar code or matrix, and / or at least one identifier detectable by radio frequency, for example in the form of an RFID chip.
- the shuttle traffic infrastructure may include at least one shuttle traffic lane along which the shuttles run, this lane including in particular several sections, some of which may be completely straight for example. All or part of the shuttle traffic infrastructure can be underground.
- the shuttles can run on at least part of the infrastructure within a tunnel extending in particular under the foundations of surface buildings and / or underground or not, pre-existing infrastructure.
- the tunnel is advantageously buried at a depth greater than or equal to 5 m.
- the use of a tunnel in the invention makes it possible to provide a greater burial depth, for example greater than 20 m or 30 m, or even greater than or equal to 35 m, 40 m or 50 m or more, so as to pass widely under existing foundations and infrastructure and not interfere with them.
- the tunnel has a cross section of generally circular shape.
- the tunnel can be produced in various ways and for example comprise sections assembled one after the other, in particular with a length of between 2.5 and 3.5 m, and a wall thickness of between 150 and 500 mm, these sections preferably being designed to withstand a sinking thrust of at least 500 tonnes.
- the tunnel has assembled segments.
- the sections or segments are at least partially made of reinforced concrete, in particular with a double layer of reinforcement.
- the tunnel may include a liner, in particular made of metal.
- a larger internal dimension of the tunnel, in cross section, in particular its internal diameter is between 1.5 m and 4 m, in particular between 1.5 and 2.5 m or between 2.5 m and 4 m, for example between 1.5 and 2.2 m or between 3 and 4 m.
- the shuttles may have in cross section a general shape at least partially matching that of the tunnel, and in particular may include a cradle for receiving at least one container or other loading unit, of arcuate shape concentric with the tunnel wall. This can allow the best use of the system by reducing the section of the tunnel not used for the transport of goods.
- the shuttle traffic infrastructure may include, as mentioned above, at least one drive cable to drive the shuttles over at least part of the infrastructure.
- the use of a drive cable reduces the cost of shuttles while providing a fast and reliable automated transportation system.
- the cable can run between two ends of a section of a traffic lane.
- the drive cable can be set in motion by one or more electric motors.
- the cable arranged in a section can be more than 1 km long, for example at least 4 km, better 6 km, for example 8 km or more, which then allows the realization of a section of 4 km or more since the cable runs in one direction pulling the shuttles and in the other when empty.
- the cable can be mounted on pulleys and tension rollers, similar to the systems used in ski lifts or chair lifts.
- the drive cable can be a rope, chain, belt or any other traction device.
- the drive cable can be located on the ground. It can also be located high up, above or next to the shuttles.
- the cable can run at a speed greater than or equal to 5 m / s, better still greater than or equal to 7 m / s, for example of the order of 8 m / s or more.
- the shuttles can include means for coupling and uncoupling independently or not from the drive cable, in particular as a function of an energy reserve.
- the motor means of the shuttles can be used for this function, as mentioned above.
- each shuttle has a disengageable mechanical clamp which closes or opens to attach the shuttle to or release the cable.
- Each shuttle can thus be accelerated, in particular when it leaves a loading and / or unloading station, to reach the speed of the cable and gradually reduce its speed or even stop, in particular when it arrives at the loading station. and / or next unloading.
- At least part of the shuttle traffic infrastructure can be railroaded. The infrastructure can then be equipped with rails on which the shuttles move. The use of rails is preferable when the shuttles are towed by a drive cable. In this case, the cable can run between the rails, parallel to them, which makes it possible to gain in compactness, and if necessary to mount the cable guide structure on a common support with the rails.
- At least part of the shuttle traffic infrastructure may have a track on which the shuttles travel, the latter being fitted with tires, for example.
- the shuttle traffic infrastructure may include at least one traffic lane, in particular at least partially buried, on which the shuttles preferably run unidirectionally.
- the traffic lane may be in a closed loop, in particular in the shape of a figure eight, with one or more penetrating, if necessary.
- the loop formed may include a succession of sections the length of which is for example greater than 1 km.
- the loop can include straight sections if desired, connected by bends which provide a link between straight sections of different orientations.
- the loop is at least partially buried, this may facilitate the digging and construction of the tunnel as well as the driving of shuttles along the loop.
- the straight sections are compatible with the use of a cable system to tow the shuttles.
- the bends in the loop can be located at the shuttle loading and / or unloading stations.
- Shuttle traffic infrastructure may have a "figure eight" loop traffic lane.
- This “eight” shaped loop may include two secondary loops, preferably interconnected.
- the interconnection is such that a shuttle can selectively control the corresponding routing element (s) to remain on the same secondary loop or switch to the other secondary loop.
- Each secondary loop can be connected to a penetrating line.
- each penetrating line comprises two traffic lanes (outward and return) within a tunnel or in two respective parallel tunnels.
- the shuttles circulate unidirectionally within the loop and bidirectionally within the penetrating lines.
- the shuttles advantageously circulate unidirectionally over at least part of the infrastructure. Each section is thus traveled by shuttles which circulate in the same direction within this section.
- the traffic infrastructure includes at least one tunnel
- the shuttles do not cross each other within the tunnel, which makes it possible to closely adapt the section of the tunnel to the section of a loaded shuttle and reduce the section of the tunnel not useful for the transport of goods.
- the invention does not exclude that the goods are transported in the infrastructure using at least one line where the goods on board shuttles circulate in a bidirectional way. This line can be two-track within a tunnel or two parallel tunnels.
- the infrastructure may include at the bend a routing system such as a rotating platform comprising a movable track portion on which a shuttle can position itself. This turntable can assume a position where the moving track comes into alignment with a shuttle infeed track, and a position where said moving track aligns with the track of the next section to be traveled.
- a routing system such as a rotating platform comprising a movable track portion on which a shuttle can position itself. This turntable can assume a position where the moving track comes into alignment with a shuttle infeed track, and a position where said moving track aligns with the track of the next section to be traveled.
- the infrastructure may include an auxiliary drive system to make the desired turn.
- the shuttles can be carried by casters or by a roller conveyor or conveyed by any other conveying system making it possible to make the shuttles take tight turns.
- the traffic infrastructure may include at least one parking area, in particular underground.
- This parking zone can be located inside or outside, for example at the edge of the traffic lane.
- the parking area is preferably large enough to accommodate several shuttles.
- a faulty shuttle can for example steer independently or be brought by at least one other shuttle into the parking area so as to extract itself or to be extracted from the traffic lane. This can make it possible to reduce the risk of a slowing down or even of stopping the circulation of the other shuttles within the infrastructure caused by the faulty shuttle.
- the parking area can be configured to repair a failed shuttle and be equipped with a maintenance station.
- the parking area can be configured to fight against a fire occurring on a shuttle and be equipped with extinguishing means and / or suction means allowing the evacuation of combustion gases.
- the parking area can be equipped with a motorized door controlled from the supervision system.
- the shuttle traffic infrastructure may include at least one shuttle pre-parked in the parking area, in particular a shuttle without loading or a shuttle equipped to fight against fire and / or for maintenance and / or repair of vehicles. 'at least one other shuttle, as discussed above.
- the pre-parked shuttle can reach a site within the infrastructure to intervene if necessary, in particular to fight against a fire occurring on a shuttle or on the infrastructure and / or to push or tow a faulty shuttle.
- the pre-parked shuttle can intervene to push or tow a shuttle with a faulty engine means to a parking zone or to a parking zone configured to fight against the fire a shuttle on which a fire occurs .
- the parking area can be equipped with a trans-bordage system to transfer goods from one shuttle to another.

- the processing, comparison and triggering of corrective actions can involve mathematical methods of artificial intelligence such as machine learning or "machine learning", for example using neural networks.
- Such a centralized supervision system can make it possible to predict the occurrence of an unwanted situation, in particular using the principle of "weak signals", and trigger corrective action so as to avoid the occurrence of such an unwanted situation. This can thus make it possible to optimize the delivery of goods and / or containers as well as the operation of the automated goods transport system by anticipating possible disruptions.
- Each shuttle may experience disruptions during its journey within the automated goods transport system (slowing down or even stopping the movement of shuttles, for example due to the reduced reception capacity of a station, breakdown, accident, fire, maintenance work on the infrastructure, etc.). It is therefore necessary to be able to reduce the consequences, or even prevent such disruptions, in order to guarantee delivery of the goods to their final destination on time.
- Each shuttle can include onboard sensors, these sensors making it possible to generate, continuously or periodically, data relating to the shuttle (speed, level of acceleration / deceleration, location, state of its engine means, state of certain components such as bearings, state of wear of its mechanical parts, remaining autonomy of its energy storage means, etc.), to the goods and / or containers it transports (destination, origin, recipient, sender, market value, degree of priority, nature, temperature measured inside the container, in particular current temperature measured and / or history of measured temperatures, weight, volume, dimensions, number of packages contained inside the container, any specific character of the goods, such as '' a fragile, perishable and / or dangerous nature, for example a chemical or fire risk, identity and / or nature of the upstream and / or downstream surface carrier, etc.), and failures on the shuttle (breakdowns, fires, etc.).
- each shuttle can be arranged to collect the data generated by the onboard sensors, in particular in real time, and store this data on the onboard data storage module of the shuttle.
- Each shuttle can also be configured to transmit the data generated by the onboard sensors, in particular in real time, to the centralized supervision system which preferably stores these data.
- Each shuttle can include, on the onboard data storage module, pre-recorded data comprising previous data generated by the onboard sensors over the same period of time and associated with a known situation.
- each shuttle can be arranged to determine, in particular in real time (except for processing delay), whether the data generated by the sensors on board at the present moment correspond to a known situation, and to independently trigger a corrective action if this is the case.
- on-board intelligence can be configured to allow remote validation of some of these actions at least by a human operator, before they are applied.
- These corrective actions may include the assignment of a new degree of priority to the container and / or the shuttle, the modification of the loading and / or unloading station where the shuttle is loaded and / or unloaded, the modification of the speed or even stopping a shuttle, recharging the battery of another shuttle or repairing another shuttle by pulling or pushing it, automatically sending an alert signal to the centralized supervision system, and / or placing the shuttle in the parking area.
- the intelligence onboard each shuttle can process the data generated by the sensors, compare this data with previous data and trigger corrective actions.
- the processing, comparison and triggering of corrective actions can call for artificial intelligence mathematical methods such as machine learning or "machine learning", for example using neural networks.
- Such on-board intelligence can make it possible to predict the occurrence of an unwanted situation, in particular using the principle of "weak signals", and trigger corrective action in order to prevent the occurrence of such an unwanted situation. This can thus make it possible to optimize the delivery of goods and / or containers as well as the operation of the automated goods transport system by anticipating possible disruptions.
