Description

The present invention relates to a stable for advertising purposes, in particular a digital stable, having a stable body, wherein the stable body has an outer wall, a display device for displaying at least one item of information, a receiving volume and a control device, wherein at least a part of the outer wall surrounds the receiving volume at least partially, wherein the outer wall has at least one outer surface, wherein the stable body is bounded outwards by the outer wall and the display device, and wherein the control device is configured to control the display device.Stables for advertising purposes in general and digital stables for advertising purposes in particular are well known per se from the prior art, for which reason a separate printed reference is not required at this point.Digital stables are increasingly being used in outdoor advertising to present dynamic content. There is a growing need for energy-autonomous and environmentally friendly solutions, in particular for locations which do not offer a direct connection to the power grid.In the prior art, digital stables are typically based on direct power supply via the public power grid. This, however, leads to a number of disadvantages. On the one hand, the installation of such steels is often associated with high costs for the installation of power lines and their maintenance. Secondly, the operation of these steels is usually not lasting, since they depend on conventionally generated energy. Especially in remote or infrastructure-poor areas, the operation of such installations is often not economically feasible or not realizable at all. Additionally, power dropouts increase the susceptibility of such solutions and can lead to longer interruptions in operation.The problem underlying the invention is therefore that known stables are dependent on a connection to the power grid for advertising purposes and thus require electrical energy generated at least partially from fossil energy carriers. This makes the stables expensive to install, are locally limited in their installation to areas that have access to the public power grid, and are also not environmentally friendly.Against this background, it is the object of the present invention to provide a stable for advertising purposes which is cost-effective to install, can be operated at an autonomous energy level and is environmentally friendly.To achieve this object, the invention proposes a steel which is characterized in that at least one photovoltaic module is arranged on the at least one outer surface, wherein the photovoltaic module is configured to supply voltage to the display device.The basic idea of the invention is to provide a stable independent of a land-bound energy supply by integrating photovoltaic modules into the stable.According to a first embodiment, the problem is solved by a stable for advertising purposes with a stable body. The stelene body has an outer wall, a display device for displaying at least one item of information, a receiving volume and a control device. At least a part of the outer wall surrounds the receiving volume at least partially. The outer wall has at least one outer surface. The stelene body is bounded outwardly by the outer wall and the indicator. The control device is configured to control the display device. The steel is now characterized in that at least one photovoltaic module is arranged on the at least one outer surface. The photovoltaic module is configured to supply voltage to the display device.The advantage of a photovoltaic module which is arranged on the at least one outer surface and is configured to supply voltage to the display device is that the otherwise unused outer surface of the stable which is not used by the display device can be used to generate electrical energy which is used for operating the display device. This eliminates the need for a wired power supply.By eliminating the need for a wired power supply, the installation costs are reduced, since only the mechanical anchoring of the steel, but not the electrical supply, has to be ensured. In addition, the stable can also be set up at locations at which a wired supply is not possible, such as at remote locations. Moreover, the energy supply is ensured in this way by renewable energies, so that the steel according to the invention is also environmentally friendly.A stable within the meaning of the present invention is a self-supporting, vertically oriented device with a housing which contains one or more technical components for displaying information or advertising content. The steel is designed such that it can be used both in the interior and in the exterior. The stable is used in particular for the presentation of digital content.The outer wall is part of the stelene body and has at least one outer surface. The outer surface at least partially delimits the stelene body. Here, the fact that the stelene body is bounded to the outside by the outer wall and the display device means that the outer wall and the display device define the outer shell of the stelene body.Preferably, the outer wall has a plurality of surfaces. More preferably, these surfaces are planar. However, in another alternative embodiment, at least a portion of the outer surfaces are curved.The advantage of planar outer surfaces lies in the particularly favorable production, while curved surfaces allow more efficient utilization of the rammer volume, so that less material is required and the rammer is more environmentally friendly.The display device serves to display at least one item of information. The display device may include a screen and electronic components necessary for the operation of the screen. The at least one item of information can be graphical information. In particular, the at least one item of information can have letters and / or numbers.The receiving volume is located in the interior of the stelen body and is at least partially surrounded by the outer wall. The receiving volume can be configured to receive components for operating the stable.Here, the control device being configured to control the display device means that it controls the display device in such a way that the desired information is displayed. This may also mean that no information is displayed.The at least one photovoltaic module is arranged on the outer surface in such a way that the photogenerator layer points outwards. "Outwards" here means pointing away from the stelen body. The at least one photovoltaic module may be a polycrystalline, monocrystalline or thin-film module.If the at least one photovoltaic module is a polycrystalline module, it is particularly cost-effective, so that the installation costs of the stable are reduced.If the at least one photovoltaic module is a monocrystalline module, it is particularly energy-efficient, so that the stable is environmentally friendly.If the at least one photovoltaic module is a thin-film module, it is particularly flexible. As a result, it can also be applied to curved parts of the outer surface.The at least one photovoltaic module can be arranged on the outer surface in such a way that an electrical connection between the photovoltaic module and another part of the steel is ensured. In particular, the outer wall can have openings for this purpose.According to a further feature of the invention, the steel has an electrical energy storage device. The energy storage device is electrically connected to the at least one photovoltaic module and the display device and is configured to receive electrical energy from the at least one photovoltaic module and to deliver it to the display device as required for operation thereof.As a result, the stable is independent of the direct energy supply by the photovoltaic modules, since the energy generated by the at least one photovoltaic module can be stored in the energy storage device and, if required, can also be output to the electronic components, in particular to the display device, if the at least one photovoltaic module does not generate energy, for example at night. In this way, the autarchy of the stable is increased.The electrical energy storage device may be an accumulator. As a result, the steel can be set up particularly cost-effectively, since accumulators have low costs with regard to their storage capacity.The electrical energy storage device may be a capacitor. As a result, the steel can be particularly environmentally friendly, since condensers have no wear and can be produced without environmentally harmful materials.If the energy storage device is configured to absorb electrical energy from the at least one photovoltaic module, this means that the photovoltaic module transmits the electrical energy arising therein by means of incident light radiation to the energy storage device by means of an electrical connection and the energy is stored there chemically or electromagnetically.When the electric power is supplied to the display device as needed for operation thereof, this means that a sufficient voltage is applied to the display device by means of the energy storage device and an electric current is provided over time such that the processes specified by the control device can be executed in the display device.For this purpose, the controller can have the control electronics necessary for this purpose. In particular, the steel may have a transformer, a direct current or inverter, a voltage converter, a battery management system, a maximum power point tracker, an overvoltage protection and / or an overcurrent protection device.The control electronics can preferably be arranged in the receiving volume of the stelen body.According to a further feature of the invention, the stelene body comprises at least one closure element, wherein a part of a surface of the closure element forms a part of the outer wall.This makes it possible for the receiving volume of the stelene body to become accessible, for example for maintenance or repair of the control electronics located therein or of the energy storage device. In this way, a container for the energy storage device and / or the control electronics, which is arranged next to the stable, is dispensed with, so that the installation costs of the stable can be reduced.The closure element is a movably mounted element which is configured to close or re-open an opening in the stelene body by a pivoting movement. In particular, the closure element can be a door.According to a further feature of the invention, the stelene body is a polyhedron and the display device and the closure element are arranged on two different surfaces of the polyhedron.This ensures accessibility of the rear side, on which interfaces for data or energy transfer are usually located.In particular, the stelene body can be a cuboid. Then, the display device and the closure element can be arranged on opposite sides of the cuboid. This ensures particularly easy accessibility of the rear side of the display device, so that maintenance or repair of the display device is facilitated. Moreover, the available surface of the handle can be utilized better, since the dimensioning of the display device and of the closure element can be designed independently of one another.If the stelene body is a cuboid, it can be provided in an advantageous embodiment that the cuboid has two dominant main surfaces, which are further preferably rectangular, but not square. In this way, a slender construction can be achieved which nevertheless has a sufficient height for positioning the display device and offers sufficient area for the display device and the closure element. In particular, the display device and the closure element can then be arranged on the two opposing main surfaces.According to a further feature of the invention, the closure element has a frame in which at least one carrier for receiving at least one photovoltaic module is arranged, wherein the frame is preferably completely filled by the at least one carrier.In this way, the at least one carrier of the photovoltaic module / s serves simultaneously as part of the outer surface, so that a dedicated outer surface on the closure element, for example by a sheet metal, is not required.The carrier can have receiving devices for receiving the at least one photovoltaic module. In addition, the carrier can have electrical conductors for transmitting the voltage provided by the at least one photovoltaic module.The carrier can be made of aluminum. However, other materials such as steel, plastic or an organic material are also conceivable.In addition to the frame and the at least one carrier, the closure element preferably has a cover element which surrounds the at least one photovoltaic module. In this way, a photovoltaic module arranged on the carrier can be better protected from weather influences.According to a further feature of the invention, the display device displays the at least one item of information by means of a bistable reflective display.As a result, the energy requirement of the stable can be significantly reduced, since such a bistable reflective display only requires energy when the display is changed, but not for maintaining the display. In addition, reflective displays do not require backlighting. In this way, the energy autarchia and the environmental friendliness of the stable can be increased.A bistable reflective display is a display device which displays contents by reflecting ambient light and in which the orientation of the elements such as liquid crystals contained in the display and used to display the contents remains in a stable state until an electric field is applied, whereby contents are maintained without continuous power supply.The bistable reflective display may be an electrophoretic display (also known as E-ink), a cholesteric liquid crystal display (ChLCD) or a twist ball display.Electrophoretic displays are particularly cost-effective and energy-efficient. Cholesteric liquid crystal displays are capable of displaying colors and can thus enable more complex information display. Twist ball displays are to a limited extent suitable for displaying different colors and / or grey levels.The bistable reflective display can have color filters or segmented color zones in order to achieve a polychromatic representation.According to a further feature of the invention, the steel has a plurality of identical photovoltaic modules.As a result, standardized photovoltaic modules can be used on the one hand, which reduces the installation costs. On the other hand, the available area of the stelene body can be utilized better. Moreover, it is possible to use the same type of photovoltaic modules for different configurations, for example different sizes, of the step, which in turn entails cost savings and thus reduces the installation costs of the step.It is also conceivable that the stable has two or more different groups of photovoltaic modules, wherein the modules within a group are identical.In this way, a higher flexibility in the design of the step can be achieved without sacrificing the advantages of standardized photovoltaic modules.The photovoltaic modules can be arranged on the outer wall in different orientations.According to a further feature of the invention, at least 50% of the outer wall is covered by the at least one photovoltaic module.This makes advantageous use of the available surface of the stelene body. In particular, the stelene body can thus be designed to be particularly small and nevertheless provide a sufficient amount of electrical energy for the operation of the display device.Preferably, at least 66%, more preferably at least 75%, more preferably at least 90%, of the outer wall is covered by the at least one photovoltaic module. In a further advantageous embodiment, the entire outer wall is covered by photovoltaic modules. As a result, the outer wall can be used even better for energy generation.The outer wall does not include, in particular, the display device.According to a further feature of the invention, the controller has a communication interface, wherein the communication interface is configured to transmit and receive control commands for the control device.This makes it possible to control the display device and also other components of the controller particularly easily by means of the control device.The communication interface is preferably a wireless communication interface. This allows even simpler control of the display device and other components of the controller.The communication interface can be, in particular, a Bluetooth interface, an NFC interface, a WLAN interface or a USB interface. Standardized interfaces of this type make possible a particularly simple and cost-effective control of the steel.A control command can be an instruction or regulation here, which causes the control device to actuate an electrical or electronic component located in the controller in a specific manner. The control command can also comprise graphic information, such as a graphic to be displayed by the display device or an alphanumeric information display.According to a further feature of the invention, the stable has an illumination device which is configured to illuminate the display device.This can increase the visibility and readability of the display device. In particular when using a reflective display, readability can thus also be ensured in twilight and at night, since a reflective display does not have its own backlighting.The illumination device can be configured in particular to illuminate a display of the display device. For this purpose, the illumination device can be configured to illuminate the display from behind. However, the illumination device can also be configured to illuminate the display from the front.The illumination device can have a brightness sensor, so that the illumination only occurs when the brightness of the surrounding area of the stable is below a defined, preferably adaptable, threshold value.The lighting device may have a motion sensor, so that the lighting only occurs when a person approaches the stable.Moreover, it can be provided that the illumination device can be controlled by means of the control device and the illumination of the display device can thus also be controlled. In particular, it can be provided that the control device receives a corresponding control command by means of a communication interface. Alternatively, the controller may have a switch which can be manually operated from the outside and by means of which the lighting of the display device can be switched on or off.According to a further feature of the invention, the controller has a temperature sensor which is configured to sense the temperature in a region of the receiving volume and to transmit it to the control device.In this way, the control device can perform the control of the display device and other components of the controller depending on the temperature prevailing in the receiving region. This allows reaction to too high or too low temperatures, which increases the safety of the steel. Moreover, the autarchy of the stable is thus improved.The stele preferably has a plurality of such temperature sensors, which are arranged at different points of the stele. Thus, the control of the display device and other stelene components can be performed even more efficiently and more safely.The temperature can be determined continuously or intermittently.According to a further feature of the invention, the control device is configured to output a warning signal as a function of the temperature transmitted by the temperature sensor.This makes possible protection against harmful high or low temperatures.The warning signal can be, on the one hand, an acoustic and / or visual warning signal, such as a signal tone or a flashing light. On the other hand, the warning signal can also be digitally transmitted information, such as a push message to a mobile terminal or a signal to a central control unit. In addition, the warning signal can be an internal signal which transmits a control command to another component of the controller. A combination of these variants described above is also possible within the scope of the present invention.According to a further feature of the invention, the stable has a ventilation device which is configured to bring about an air exchange between the receiving volume and the external environment.As a result, the temperature in the intake volume can be regulated and, in particular, kept below a prescribed threshold. This increases the safety and also the autarchy of the stable.For the purpose of ventilation, it can be provided that the stele, in particular the outer wall of the stele, has ventilation slots. This allows air to be exchanged.In particular, it can be provided that the ventilation device is configured to bring about an air exchange between the receiving volume and the external environment on receipt of a warning signal by the control device.As a result, in the event of imminent overheating of the stable, the temperature in the receiving volume can be lowered by air exchange with the environment, so that overheating of the stable and thus of the electronics located in the stable can be prevented. This increases the autarchiness of the stable.Further features and advantages of the invention will become apparent from the following description with reference to the figures.
