Definitions

  • the general field of application of this invention is in the sector of infrastructure adaptation, to support the transition towards the progressive computerization of urban environments, in line with the evolutionary scenarios typically identified with the expression "Smart City”.
  • a computerized environment is an environment in which there are numerous sensors, i.e., devices capable of acquiring environmental information of all kinds, in order to reconstruct a computerized representation of the environment itself, in a manner that is as comprehensive as possible.
  • these sites must be connected to a telecommunications network, in order to transfer the acquired data to a special control center, or even to be interconnected each other.
  • these sites can also accommodate any actuation devices, or devices that, if necessary, carry out some action: for example, the activation of an alarm siren, or the switching on of some light signals, or other actions of this type.
  • lamp posts have been designed (and invented) to illuminate a "Smart City", that is an intelligent city, characterized by a significant presence of technological systems, i.e.; they are designed to function optimally with respect to contingent environmental situation, which must therefore be detected, analyzed, and appropriately managed.
  • WO 2021120571 (A1) ["5G Communication module-based intelligent street light” - Chen Yong et al. - June, 24th, 2021 ] discloses an "intelligent street lamp” which, among other things, also partly uses solar energy to feed itself, and which is designed to house various types of devices, including a small server capable of executing control programs for all the components integrated into the lamp itself.
  • This "intelligent street lamp” is also equipped with communication systems that allow it to be connected with other devices installed remotely, as well as with a control center.
  • the particular conformation of the support structure of the street lamp allows to obtain a room inside it, suitable for installing a good number of electronic devices (therefore in such a way that the components installed there are substantially invisible) that are used in the "Smart City”.
  • WO 2021109604 ["Smart City Lighting Device” - Wang Renyin et al. - June, 10th, 2021 ] indicates another street lamp for "Smart City", similar to the one indicated in the previous patent application, in which particular attention is paid to energy aspects, proposing some optimizations relating to the production of photovoltaic energy and to the lighting regulation.
  • the street lamp is in fact a site designed to host the installation of various "Smart Objects”.
  • CN 2113146337 (U) ["Street lamp for smart city” - Wang Xiaoxia - 7 July, 7th,2021 ] is patent application for utility model, it describes a further form of structure of a street lamp that allows, among other things, also to adjust the physical position of the actual lighting bodies.
  • the street lamps installed in urban environments to provide for the public lighting can not only be managed in an intelligent way, in order to improve lighting by optimizing consumption, but they also constitute an ideal place for housing a multitude of sensor and actuator devices, as well as communication terminals, eventually constituting the nodes of a real network of "Smart Objects".
  • the known art has certainly implemented this potential multifunctional use constituted by the public lighting network, so that it proposes new-concept street lamp, which illuminate in an optimized way (according to the most varied criteria that depend from case to case) and at the same time constitute physical nodes of the networks of "Smart Objects” that will characterize the “Smart Cities” of the near future.
  • the general purpose of the present invention is to indicate a system for the adaptation of existing public lighting systems, characterized by street lamps whose support structures (which are substantially poles) do not have spaces for the installation of other devices, even if these last are small; and the power supply is present only when the street lamps are on.
  • the desired adaptation provides for a redevelopment of the street lamps, which transforms them into “intelligent street lamps", and which allows them to be used as sites to install the various "Smart Objects" that enable the dissemination of typical applications of a "Smart City”.
  • this system for the adaptation of existing public lighting systems must have some essential characteristics, certainly including that of providing a suitable compartment to accommodate all the "Smart Objects" that may reasonably have to be installed in an urban site like a street lamp for public lighting.
  • said system for the adaptation of existing public lighting systems must allow to adequately manage the power supply required by the "Smart Objects", taking into account that, as a rule, the street lamps are powered just when they are on, unless to foresee an invasive intervention for modifying the existing lighting control logics.
  • the aims set for this invention are achieved by means of a system, or kit, for the redevelopment of a street lamp for public lighting which includes at least:
  • the main advantage of the present invention consists in the fact that its teachings appear essential to redevelop a normal street lamp for public lighting and transform it into an "intelligent street lamp”.
  • this transformation can be carried out without having to implement invasive or complex interventions on the existing street lamps, obtaining a more than decent result also from an aesthetic point of view.
  • the number 100 indicates, as a whole, a modular system for the adaptation of public lighting systems according to the invention, wherein the various pieces that compose it are shown detached from each other. for greater clarity.
  • the number 110 indicates two boxed elements, internally empty, and therefore designed to house electronic devices, which, generally, are the so-called “Smart Objects” necessary to implement the IT applications that will characterize the "Smart Cities” of the future.
  • a first important characteristic of said boxed elements 110 is that they are open both above and below, in fact they essentially consist of a side wall and have neither a bottom nor a lid.
  • edges of the upper and lower opening are substantially of the same shape, so that when a pair of equal boxed elements 110 are stacked on top of each other, the edge of the upper opening of the boxed element 110 that lies below mates perfectly with the edge of the lower opening of the boxed element 110 which is located above, thus giving shape to a larger boxed element whose capacity is substantially given by the sum of the capacities of the two stacked boxed elements.
  • boxed elements 110 By stacking a greater number of boxed elements 110 it is possible to obtain an increasingly larger compartment to house larger "Smart Objects", or more in number, so as to satisfy almost every installation need.
  • a second characteristic of said boxed elements 110 is that they are arranged to be hooked to a support structure of a street lamp for public lighting. In the most typical case, they are designed to be hooked to a light pole.
  • the coupling subsystem is indicated in Figure 1 with the number 120 and, as it will be better explained later, said coupling subsystem is designed to be able to be coupled to the almost total variety of light poles actually present.
  • a third characteristic of said boxed elements 110 is that they, again in the area where said hole arranged to allow said power cables to enter inside the boxed body 110, i.e., in the area closest to the light pole, also have a vertical conducting element, indicated in Figure 1 with the number 112, composed of at least two conducting elements isolated from each other that can be kept at a different electrical voltage, so as to supply power to the components housed inside the boxed element.
  • said conformation and positioning of said vertical conducting element are such that, when two or more boxed elements 110 are coupled one on top of the other, said conductive elements 112 of said two or more coupled boxed elements 110 form an electrical contact with each other thus to compose a continuous conductive line that runs vertically throughout the internal space, obtained by coupling said two or more boxed elements 110.
  • said vertical conducting element 112 which in Figure 1 is shown detached from the boxed element 110 just to make it more clearly visible, is of sufficient length to completely cross the entire height of each single boxed element 110.
  • a fourth characteristic of said boxed elements 110 is that they, in the area opposite to the hooking area, have a protuberance, indicated in figure 1 with the number 111.
  • Said protuberance 111 allows to obtain holes, or slits, for the passage of air between the inside and the outside of each boxed element 110, it being possible that these slits face downwards even when a boxed element is coupled with another equal boxed element located under it (this is possible precisely because said slits can be made in the lower part of the protuberance 111).
  • said protuberance 110 offers the space to house, if necessary, also a fan that can be activated to induce forced ventilation both at the inlet and outlet.
  • the coupling between pairs of stacked boxed elements 110 involves the interposition of a gasket, indicated in Figure 1 with the number 131, and which allows to ensure an optimal and well-sealed coupling.
  • a further separation element may be positioned between two coupled boxed bodies, indicated in Figure 1 with the number 132.
  • said separation element 132 is accommodated in a suitable seat accessible from the upper opening of the boxed element 110, and acts as a support base for components housed inside the boxed element 110, and, eventually inside the one above it; given that, depending on the implementation forms, the support seat of said separation element 132, can be placed at various heights of the boxed element 110.
  • the overall redevelopment system 100 must then be completed with closing covers for the bottom and top.
  • the bottom lid 142 has holes, or slits, benefiting from the fact that, when mounted, it faces downwards, while the top lid it incorporates a flat metallic element suitably shaped to act as an antenna for a mobile radio telecommunications terminal.
  • a mobile radio terminal is housed inside the boxed element placed higher, given that the communication functionality is substantially essential in any "Smart Object" network; while a power subsystem equipped with a rechargeable battery is housed inside the lower boxed element, given that the power subsystem is a subsystem which, however efficient it may be, it must still dissipate heat.
  • the use of a battery is required in all cases where the lamp to which the adaptation system 100 according to the invention is applied is powered only when the lamp is on. In this case, when the power supply is present (i.e., when the street lamp is on) it is essential to accumulate the energy necessary for the operation of all the "Smart Objects" even when the public lighting system does not provide power.
  • a continuous conductive line which is composed automatically by coupling the various boxed elements 110, can be used to power all the "Smart Objects" in parallel, as well as one or more telecommunication terminals.
  • said power line can be kept live by a single power supply system, positioned inside the lower boxed element (i.e., the one in which it is easier to dispose of the heat).
  • the telecommunication terminal finds its preferred location inside the boxed element 110 which is located further down.
  • the terminal can be connected with very short cables to an antenna integrated in the top cover 141; since the top cover 141 is generally wider than a normal mobile radio terminal, an antenna with particularly good performance can be integrated into it; especially since in this position it should not even have particular shielding obstacles.
  • the composite vertical conductor element which is automatically composed when the boxed elements 110 are stacked, in addition to the basic function of distributing the electrical power supply, can also implement a data line on a fast bus, obviously providing for the composition of other conductive lines isolated from each other (in this regard there are several standards to implement said data bus).
  • the compartment that is created using the teachings of the present invention not only offers a housing of adequate and extensible dimensions to install a number, also significant, of "Smart Object", but also provides the power supply, data connectivity, and ventilation for all the “Smart Objects" installed on the site.
  • FIG. 2 shows the detail of a boxed element 110 seen from below. From this view it is possible to appreciate the ventilation holes which are made in the downward-facing part of the protuberance 111. You can also see a separation element 132 positioned inside the boxed element 110 in an intermediate position between the lower and upper opening of the boxed element 110.
  • the boxed elements 110 are equipped with a coupling subsystem which include a coupling block, indicated with the number 121, fixed to the side wall of each boxed element 110.
  • Said coupling blocks 121 are fixed to the boxed element 110 in various ways; for example, with screws, or with joints, or with both techniques, or they can also be fixed with permanent fixing techniques.
  • said coupling block 121 is connected to flexible bands, indicated in Figure 3 with the number 122, which allow it to be securely tied to any pole.
  • Said coupling block 121 when the boxed element 110 is hooked to the support structure of a street lamp, it is then interposed between the actual body of the boxed element 110 and the supporting structure of the lamppost to which it is attached.
  • said coupling block 121 has a hole, through which these cables can penetrate inside the boxed element 110; evidently this hole being aligned with the hole present on the side wall of the boxed element 110.
  • the face of the coupling block that must come into contact with the pole can be made of deformable materials, so as to allow perfect coupling with any curvature of the surface on which they are placed.
  • the coupling subsystem 120 can be made practically universal, being able to couple it to poles of any shape and thickness, since also the bands 122 are obviously flexible and can be adapted to any pole.
  • a redevelopment system 100 of street lamps for the adaptation of public lighting systems in order to support the massive development of "Smart City” applications, and implemented according to the teachings of the invention is suitable for practically any type of street lamp; and it is able to transform any street lamp into a real "smart lamp", suitable for creating a site able to host the nodes of a network of "Smart Objects” for a “Smart City”, even in a scenario where computerization is particularly intense.
  • Said redevelopment system 100 is particularly adaptable to almost all cases that can be imagined today.
  • the invention has a different purpose, and aims to solve the problem of creating an infrastructure that can also support evolutions with a high degree of unpredictability and contingency. Therefore, the compartment is designed to house, power and connect any generic "Smart Object".
  • the compartment that is offered is particularly suitable for housing a power supply system, at least a telecommunication terminal and calculation and memory means, as this minimum equipment is apparently essential to implement any advanced operating logic of all the "Smart Objects" regardless their function.
