The present invention relates to a mobile multifunctional base station for a smart home system. The invention also relates to a system for mobile internet connection for internet-based stand-alone products, as are known, inter alia, from the “smart home” area.
State of the art
As it has been known in the present field for a long time, there is now technically the possibility to let household and multimedia devices interact and to control them centrally. The technological prerequisites required for this are provided by the so-called smart home technology, which on the one hand can automate everyday processes, the so-called home appliance automation, and on the other hand device settings such as heating, light, awnings or blinds, loudspeakers, or others Household appliances (refrigerator, blender, etc.) can be quickly adapted to personal needs using a computer or smartphone. The term “smart home” is generally to be understood as an information and sensor technology-upgraded, internally and externally networked home, which is usually aimed at increasing the quality of life and living, operational and burglar security and energy efficiency. Furthermore, not only is the device-less control, for example via voice commands or gesture control, becoming increasingly important, but also the interaction of household and multimedia devices with a wide variety of sensors in the household. The basic basis for this is generally the use of a so-called gateway as a central control unit for operating such a smart home system or such a smart home system.
A multifunction unit for controlling or regulating such a smart home system in a household can, for example, be the DE 10 2016 222 794 A1
are removed, in which one or more electrical network devices can be controlled in an intelligent home network, and in addition environmental signals can be provided in an environment of the multifunctional unit, on the basis of which a corresponding control device can be controlled. The multifunction unit of the known prior art furthermore has, in particular, a housing which is designed for wall mounting of the multifunction unit in the household of the home network.
Although many of the sensors and actuators used in a smart home system, such as motion detectors, lamps, weather stations, cameras, etc., are weatherproof, energy self-sufficient and built for outdoor applications, the gateways required for control have so far been exclusively for use in closed rooms with an installation at a predetermined location. In addition, the gateways of the previously known systems require a permanent, wired connection to the Internet throughout and must also be connected to a voltage source (e.g. a socket) via a permanent installation.
Accordingly, it was not possible with the previously known plants or systems to be operated in locations which do not provide a wired Internet connection or a power connection. Furthermore, it is also not possible, inter alia because of the lack of predefined protection classes or protection classes, to use the known systems or systems in locations where they are exposed to increased moisture, dust or similar unfavorable external influences. Protection against impact, impact or penetration of foreign bodies is also not provided in the previously known systems or systems. However, there is not only a need for such systems or systems or for the functions that such systems or. There are not only in safe places where the aforementioned unfavorable external influences do not generally occur, i.e. usually in homes or other fixed buildings (company buildings, etc.) Systems have to offer. For example, other "unsafe" locations are conceivable where such systems or systems could be used. For example, it is conceivable that users may want to use the multiple functions of a smart home system in portable spaces, such as on a boat (yachts, sports boats, etc.), in a mobile home or in a mobile container, or even in remote locations , such as in agricultural operations, production halls, auto repair shops, boat houses, holiday homes, garden houses, hunting lodges, etc. Accordingly, there is an essential need in the present field of technology to provide a system or a system for operating a smart home network that the withstands the aforementioned external influences and is also able to be used in a portable manner.
Summary of the invention
The above-mentioned and other problems of the prior art are solved in the solution proposed here by a multifunctional base station for a smart home system.
According to a first aspect of the present invention, the multifunctional base station for a smart home system comprises as components at least one housing, a modem arranged in the housing, a gateway arranged in the housing, which is connected to the modem, a ventilation device, at least one power supply for the modem and the gateway, and a switch for controlling the power supply of the gateway, for a delayed activation of the gateway compared to the activation of the modem, the multifunctional unit according to the invention forming a portable unit. In principle, the switch is required here for both the modem and gateway to be supplied with voltage simultaneously via the power supply (ON / OFF), which means that these components are basically switched on at the same time. However, since the gateway searches for a WLAN network due to its function immediately after it is switched on, but the modem was usually not able to provide this WLAN network due to the connection process, which usually takes a little longer, the gateway usually works without a successful WLAN connection automatically returns to an unwanted stand-by mode. In order to achieve a time delay between WLAN network establishment and dialing in the gateway, it is necessary that the gateway can be activated with a time delay. Corresponding cabling is provided with the switch in the housing. If you now activate the power supply of the base station, for example by plugging the power cable into a voltage source (socket), the modem first establishes a connection to an LTE broadband radio network. An existing connection is then indicated, for example, by LEDs on the modem. If the modem has established a connection to the Internet, the gateway is now switched on by pressing the switch. This functional order can prevent the problem of the unwanted stand-by mode of the gateway.
According to a further development of the present invention, the housing is designed as a dust-proof, shock-proof housing that is protected against water jets, wherein the housing can be a multi-part empty housing, the components of which can be connected to one another. The housing can be designed, for example, as a square box. The housing can consist of at least one hollow base body, a cover and a seal arranged between the base body and the cover, wherein the cover of the housing can be transparent, whereby a display of the modem and / or a display of the gateway can be viewed, so for Example to see the LEDs of the modem and to see if the modem has established a connection to the Internet. The cover and the base body of the housing can be firmly connected with screw plugs or the like, the seal between the cover and base body being clamped in such a way that the connection between the cover and base body meets the requirements of protection class IP 65 65 according to DIN EN 60529.
An additional further development of the present invention implements the power supply as an internal power supply arranged in the housing, for example in the form of an optionally rechargeable battery supply. If, for example, the base station is operated with an independent additional external power supply, for example a solar cell, a wind turbine of sufficient dimensions, or the like, the base station can work completely independently in the long term.
Alternatively, the power supply can be an external power supply, for example operated with 230V AC or 12V DC. With the 230V variant, a voltage source with 230 volts is usually available on site, with the advantage that external devices such as cameras and their power supplies can also be supplied via this voltage source. In addition, no corresponding step-down module is required for this version. In the alternative version with a 12V power supply, the base station can be plugged in and operated at any cigarette lighter socket, as is usually available in mobile homes, boats, etc. This allows a further increased user friendliness to be achieved. The power supply can be implemented by means of a weather-resistant and tread-resistant power cable which connects the inside of the housing to the outside of the housing, wherein a protective sheath can be provided around the power cable, for example in the form of a grommet according to protection class IP 65 in accordance with DIN EN 60529 the use of only one connection cable of the base station can greatly increase its user friendliness. In order to make this weather-resistant and sturdy, the power line used can be installed in the H07RN-F version for high mechanical loads, also for permanent outdoor use. In order to maintain the protection class consistently, a grommet with protection class IP 65 DIN EN 60529 can also be used to lead the connection cable through the housing. By installing all components in a single housing with only one connection cable with plug, all installation work for the base station on site is eliminated. The station can be transported to any location, plugged in and thus easily put into operation. Any radio based sensors and Actuators can also be set up on site without installation work and preferably connect automatically to the central control unit, the gateway of the base station, which further increases the user-friendliness of the base station according to the invention.
Another problem has arisen due to the use of relatively sensitive assemblies from domestic technology. If the user opens the housing, for example to insert the LTE Sim card or to reset the gateway or the modem if necessary, moisture can get into the housing. This problem is solved by the ventilation device according to the invention. This consists, for example, of at least two parts, which are arranged offset in height on two opposite walls of the housing, as a result of which a chimney effect can be produced in the housing in order to be able to reliably remove moisture from the housing and thereby protect the components in the housing from damage , Due to the dust-tight and jet-proof design of the housing, this moisture could no longer escape and would lead to component damage, for example due to corrosion.
According to another further development of the present invention, the housing and / or the ventilation meets the requirements of protection class IP 65 according to DIN EN 60529. Furthermore, the gateway can be a multi-protocol gateway. Accordingly, the gateway operates a so-called "open system" and is used for manufacturer-independent control and management of all sensors and actuators, for example with EnOcean® and Z-Wave radio technology, ZigBee and Wireless M-Bus. Therefore, many components from well-known third-party manufacturers can be integrated. The multiprotocol gateway is flexibly expandable, can be individually configured and controlled via an app. Events, messages and measured values are documented and, if necessary, a warning message is sent to mobile devices (smartphones, tablet PCs). Additionally or alternatively, the modem can be an LTE modem with multi-band support and can include an LTE Sim card, for example for connection via LTE (4G), UMTS (3G) and / or GSM (2G). In addition or as an alternative to this, the connection between the modem and gateway can be implemented using a LAN cable.
Furthermore, in the present invention, the modem can be positioned in the housing by means of a U-profile fastening, the modem being detachably attached to the U-profile fastening, for example by means of flexible rubber bands. While the gateway can be installed in the housing at designated mounting points without structural changes to a mounting plate of the empty housing, a special fastening in the form of the U-profile may be necessary for the LTE modem. It can be a U-profile that protrudes vertically from the mounting plate of the housing. This U-profile enables the modem to be fastened on the one hand with silicone straps, on the other hand it grants access from below to the SIM card slot of the modem and to the slot of the power cord, which further increases the user-friendliness and usability of the base station according to the invention.
Generally speaking, the previously proposed systems of the prior art were able to implement the advantages of a smart home system, including even a high-performance LTE modem for establishing a permanent Internet connection, but these could not be used in a portable manner, since the components required for this were consistently used are intended for a fixed installation that cannot be moved and are not suitable for applications in damp, dusty and other adverse environmental conditions. However, the present solution now offers a solution to this problem in that the installation of all the components necessary for the operation of such a system can be implemented in a single housing, in particular a dustproof and jet-proof electrical installation housing, so that such a system can now be implemented on everyone can be operated anywhere. The base station according to the invention can also be used as a central control unit of a complete smart home system, as a mobile hotspot with WLAN router for stand-alone products in the smart home sector, as a receiving system for streaming music and TV via the Internet, as a stand-alone Intrusion detection function, as a self-sufficient permanent video surveillance, or for use as an energy monitoring device for various devices at any location.

Preferred embodiments of the invention
In the following description of the preferred embodiments of the invention, the figures represent the subject matter of the invention only schematically. The preferred embodiments of the invention are shown in the drawings and are described in more detail below.
1 shows a top view of a schematic structure of a base station according to the invention, with an empty housing or housing 1 , a modem 27 , a gateway 28 , and a LAN cable 39 as a connection between the modem 27 and the gateway 28 , Furthermore shows 1 one by one on the case 1 external switch 25 broken line 32 in the form of a power supply connection cable for the gateway 28 , as well as a line 33 in the form of a power supply connection cable for the modem 27 , The administration 32 for the gateway 28 serves to connect the gateway 28 with one in the case 1 arranged double socket 22 , so with a socket of the double socket 22 , The administration 33 for the modem 27 serves to connect the modem 27 with the one in the housing 1 arranged double socket 22 with the other socket of the double socket 22 , Furthermore, in 1 the ventilation device 24 shown, which consists of two parts, which are offset in height on the two opposite side walls of the housing 1 are arranged. It also shows 1 a connecting line 29 with external plug for a 230V power supply, the cable 29 through an implementation 26 through a side wall of the housing 1 is passed through.
To the gateway used 28 , which can usually be provided for wall mounting indoors, in a portable state, it was placed in the housing 1 mounted on a mounting plate provided therein. The housing 1 is manufactured according to protection class IP 65 in accordance with DIN EN 60529, ie it offers dust-proof protection against foreign bodies and complete protection against human contact, as well as protection against water jets (nozzles) from any angle. The degree of protection "IP" according to DIN EN 60529 generally indicates the suitability of electrical equipment for various environmental conditions as well as protection against accidental contact with humans and animals, with the first code indicating the degree of protection against dust and the second code indicating the degree of protection against water. In doing so, protection against dust between classes 0 to 6 and protection against water between classes 0 to 8th distinguished. As a rule, the higher the number, the better the protection. The housing 1 is therefore dustproof and protected against water jets. To ensure the permanent required for use Internet connection for the gateway 28 was the modem 27 as another component in the housing 1 integrated. It is an LTE modem 27 with multi-band support for connection via LTE ( 4G) , UMTS ( 3G) and GSM ( 2G) , The modem 27 requires an LTE Sim card to operate. The modem 27 is in this version with the gateway 28 via the LAN cable 39 connected, but can in principle also be implemented by a wireless connection. The modem 27 can be, for example, an LTE Category 4 modem, such as a FRITZ! Box 6820 LTE, and therefore preferably offers the following performance data:
- - up to 150MBit / s download speed;
- - up to 50Mbit / s upload speed;
- - Multi-band support for tape 1 . 3 . 5 . 7 . 8th and 20 ;
- - Channel width support 1.4 . 3 . 5 . 10 . 15 and 20MHz;
- - Support of the Internet protocols IPv4 and IPv6.
While the gateway 28 at the designated attachment points without changing the mounting plate of the housing 1 mounted, it can be used for the modem 27 be necessary to provide a special attachment. For example, a fastening in the form of a U-profile can be attached to the mounting plate, which is perpendicular to the mounting plate, that is to say from the plane of the drawing in 1 protrudes. The U-profile allows the modem to be attached on the one hand 27 For example, with rubber bands, such as silicone bands, on the other hand, it allows access to the SIM card slot and to the power cord slot due to the space-saving fastening on the underside 33 of the modem 27 ,
In order to increase the user friendliness, it is provided here that only a single connection cable in the form of the power cable 29 leads to the mobile smart home base station. This, in turn, is weather-resistant and tread-resistant, for example in the H07RN-F version (according to the harmonized core identification for cables and insulated cables) for high mechanical loads, which means that it can also be used for long-term use outdoors and thus still independent of the location Supported base station according to the invention. In order to maintain the degree of protection throughout, was carried out 26 the connection cable 29 a grommet with degree of protection IP 65 DIN EN 60529 used. By installing all components in a single housing 1 with just one connection cable 29 With the plug, any installation work for the base station according to the present invention is eliminated at the same time. As mentioned earlier, however, this implementation leads to a problem in that when both the gateway 28 as well as the modem 27 at the same time over the cable 29 are supplied with voltage, these components also switch on at the same time. Because the gateway 28 immediately after switching on for a WLAN network, the modem 27 however, at this point none has been set up, the gateway goes 28 in a stand-by mode. To prevent this problem, the gateway 28 the present embodiment by the additional on the housing 1 attached switch 25 switched on with a time delay, which is due to the appropriate cabling 32 in the housing 1 he follows. Now plug in the power plug of the cable 29 into a socket, builds the modem 27 first establishes a connection to the LTE broadband radio network, and indicates the existing connection by means of LEDs, a display, or the like. Has the modem 27 a corresponding connection is established by pressing the switch 25 the gateway 28 switched on, i.e. at a time when the Internet connection already exists, and can accordingly be successful with the modem 27 connect.
The housing 1
is about the ventilation device 24
added, for example, moisture or excessive heat from the interior of the housing 1
to be able to derive. How one 1
can see the ventilation device 24
of two components, which are offset in height on two opposite walls of the housing 1
are arranged that a chimney effect is generated. The chimney effect is a physical effect that causes vertically directed air flows and is based on natural convection, i.e. on the principle that warm air has a lower density than cold air, which creates thermal convection and air through the upper (left) Component of the ventilation device 24
emerges, see for example the component of the ventilation device 24
on the upper left side of the case 1
, Inside the case 1
This creates negative pressure and the external pressure pushes air through the lower (right) component of the ventilation device 24
, see for example that the component of the ventilation device 24
on the upper left side of the case 1
, in the housing 1
, whereby this is also heated. This leads to a self-preservation of the chimney effect. Venting is necessary 24
This is because, for example, large temperature and pressure differences between a closed electrical installation housing and the surrounding air, especially in electrical installation housings with a high protection class, lead to considerable condensation in the electrical installation housing. The vent 24
, for example known from the DE 10 2013 111 992 B3
, conducts warm and possibly humid air at the top of the casing 1
to the outside, while cooler air is drawn in from below, heating the air in the housing 1
among other things, through the generation of heat from the components 27
inside the case 1
is caused. Generally, the temperature band in which the components widen 27
inside the case 1
can be used by installing in the housing 1
up and down. This is how the components are created 27
inside the case 1
due to their own working temperature in the housing 1
at cold temperatures, heat that stands out clearly from the ambient temperature. At very warm temperatures, however, the components 27
inside the case 1
cooled down by the chimney effect and the resulting air circulation.
Because the power supplies of the components used 27 . 28 may not be intended for use outdoors or in locations with conditions such as outdoors, in the present embodiment they will also be in the housing 1 integrated. This is done on the mounting plate of the housing 1 the double socket 22 mounted in which both power supplies are plugged in. The power supply of the gateway 28 therefore takes place via the built-in switch 25 and the corresponding internal wiring 29 . 32 . 33 , The double socket 22 is via the connection cable 29 powered by a power plug. After plugging in the power plug, the modem builds 28 the internet connection. Then the gateway 27 switched on. Since this variant has a voltage source with 230 volts on site, external devices such as cameras and their power supplies can also be supplied via this voltage source and no further step-down module is required.
Aside from the in 1 schematically shown mobile base station in the version with 230V, the mobile base station can be implemented in further versions, for example as a version in operation with 12V DC voltage, as in 2 shown schematically. For operation with 12 volts, the base station is equipped with an automotive on-board voltage connector 30 and provided with a H05RN-F version. This means that the mobile base station can be plugged into any cigarette lighter socket. Because the gateway's power supply 28 for a voltage conversion from 230V mains voltage to 7.5V direct voltage, it cannot be used here directly. Therefore, a solution had to be provided to convert 12V DC to 7.5V DC. In order to meet the high requirements for industrial use, a so-called step-down module is used 23 be used that meets the industry standard. The step-down module 23 has a receptacle for plugging onto a standard rail, in addition to the U-profile for attaching the modem 27 is integrated, between the mounting plate and the back of the modem 27 ,
Various manufacturers sell cameras, for example, which can be operated via a power supply unit that converts 230V AC voltage to 5V DC voltage. In order to be able to operate such cameras in the low-voltage range with the base station according to the invention, a further voltage converter was used in this embodiment 34 in the housing 1 integrated, which can convert 12V DC to 5V DC. The voltage converter 34 is over a cable 41 from a central junction box 36 supplied with 12V DC voltage. At the same time, the central junction box 36 over lines 37 and 40 the modem 27 and the step-down module 23 for the gateway 28 supplied with 12V DC voltage. From the module 34 runs a cable 35 through the spout 26 of the housing 1 out of this, at the end of which there is a USB connector. All external devices that require a USB connector with 5V DC voltage can now be connected to this connector.
As a further alternative embodiment, the base station according to the invention can be used in battery operation, the base station for battery operation being essentially identical in construction to that described in and in FIG 2 12V embodiment shown. Here, only the automotive on-board voltage connector is used 30 waived. The cable ends are then, for example, directly connected to the voltage source, such as a commercially available car battery.
Preferred embodiments of the present invention have been described above, but the present invention is not limited to the preferred embodiments described above. Various modifications in the design can be made without departing from the invention as specified in the scope of the following claims.
