Abstract

A universal stand-alone device that combines more than one building automation application, including monitoring and smart metering applications, in one device and works without connecting to a central gateway or network device with at least one required sensor, processing logic, and at least one Actuator that controls directly an electrical consumer, located in the same device and housing.
This limits the fact that these various building automation applications that the device can handle can be alien to each other, eg lighting and heating control.

Description

The invention relates to a universal decentralized building automation device also called "smart home device". Such devices are used to control devices and home automation in the context of building automation.

The current state of the art knows various building automation applications, such as networked devices for lighting control, heating, ventilation and air conditioning control, networked meters for recording consumption values (water, electricity, heat, gas, etc.), intelligent home appliances (TVs, speakers, washing machines, etc .) and sensors for recording environmental values (temperature, brightness, air quality, air pressure, presence detection).

To achieve common building automation solutions (heating, lighting control, monitoring tasks) a variety of different devices (servers, sensors, actuators) are used in the current state of the art.

The networking via radio or cable, the power supply by means of cables or batteries and the maintenance of many individual devices is complicated and expensive.

A greater spread of building automation systems is opposed by the high total costs, maintenance overhead.

The installation effort for a complete building automation system is therefore often not worthwhile for smaller units.

Building automation systems covering a larger area, or more. Floors have systemic limitations on reach, as all devices communicate via a central gateway or server and the distances are too large for some transmission standards. Battery-powered devices, in particular, often use extremely economical radio standards (for example Bluetooth LE) with a very limited range and resulting connection problems even in a single-family home environment.

The known control devices or servers are usually housed in cabinets or set-up devices, which are then connected to sensors, switches or actuators.

Many wireless sensors are powered by batteries or accumulators to reduce installation costs. Conversely, this means longer-term maintenance.

Sensors and switches are also installed in commercially available flush-mounted boxes or the devices are designed for wall mounting.

Flush-mounted boxes typically have an inside diameter of 60 mm and a depth of at least 40 mm in Europe.

As of 2018, 80-90% of newly built houses will be equipped with floor, wall or ceiling heating or air conditioning systems. These houses almost always have flush-mounted boxes at eye level with integrated power supply (AC or DC) and optional data lines. A single room control of heating systems is required in many EC states in building law.

The known control units already solve a variety of different automation tasks, such as light and heating controls, but they either do not fit into a single commercially available flush-mounted box and you need more external devices (servers, sensors, actuators).

Known stand-alone solutions are currently available only for specific applications (e.g., smart home thermostat).

The "typical" flush-mounted box of the individual room control is in the optimum range (1.5 m height, in each room centrally near the door) for use as a place of accommodation of a compact smart home device.

Another major problem in the current state of the art is a higher probability of failure compared to conventional control techniques and security concerns on the part of the end user.

The object of the invention is to reduce known disadvantages of the prior art and to reduce costs.

The object is achieved with the features of the claims.

The invention is a control device which has the goal to implement all typical space-wise recurring automation applications with a single device, waiving external sensors, user interfaces, gateways, actuators, servers or control units.

However, the device according to the invention does not specify the field of application, but is designed in such a way that atypical automation applications can also be solved. It should be universally applicable. The arithmetic units can be programmed individually, so that any actions can be performed on any sensor values, external data or user input.

The typical recurring automation tasks require sensors, switches and actuators, which in the prior art make several individual devices per room necessary.

To reduce the installation cost of a smart home system in the device according to the invention, the necessary sensors, processing units (processors), power supply, EA devices for user interaction, interfaces and actuators (means relay, dimmer, thyristor, etc.), which together can form its own universal smart home system, integrated in a housing.

The device is fully functional without an external gateway or server.

Although occasionally more sensors are necessary (for example, outside temperature sensor, gas consumption measurement), the installation cost of the overall building automation system with the device according to the invention is greatly reduced. This reduces installation costs significantly, especially in small apartments and houses (EFH, ZFH). Already with a single device can solve extensive control tasks.

The device according to the invention is characterized in that it is designed as a drop-in replacement for a wall thermostat (used in the context of single-room control).

The position is predestined for further room-related control tasks, such as air conditioning control, roller shutter control or lighting control. At the same time, the device is equipped with a touch-sensitive display to indicate current states and record user input.

It can by the design but also in the box of a commercial flush-mounted switch, socket or similar. to be built in.

The device according to the invention is able to control any electrical consumers, as well as network-capable "smart" consumers. Actuators (relays, dimmers, thyristors, etc.) are located in the device for controlling heating actuators, motors, lamps, fans, etc., interfaces (KNX, CAN bus, RS485, TTL, WLAN, Bluetooth, proprietary 433 / 868 / 915Mhz radio modules) for controlling "smart" devices, actuators, switches, sensors or household appliances and conventional control outputs (analog output, PWM output, digital output).

The device according to the invention follows a decentralized approach. It carries out the local control tasks, as far as possible, in the decentralized, "spatially" subnetwork. It serves as a local server or gateway for "smart" devices in the "near" environment and is aimed at linking to similar devices of the invention in other areas / spaces, e.g. To solve space-spanning automation tasks. This greatly reduces the susceptibility to error of the room-by-room repetitive automation tasks, since each room or section forms its own independent "smart home subnetwork" and other subnetworks are not affected if one subnetwork fails.

A combination of all decentralized devices according to the invention on a server is possible and wanted. It is conceivable, for example, a communication module in the operating system of the device according to the invention, which separately with a central Server (eg KNX, Openhab, FHEM Server) communicates. The "central server" can also be an inventive device, since this has the necessary components. If the declared "main server" fails, technically known fail-over solutions can be implemented.

The compression of many network components in the device according to the invention reduces the overall network load (bus load) and "radio load", which improves the overall stability of the smart home network.

The devices according to the invention can be interconnected via various wireless and wired interfaces (W-Lan, Bluetooth, CAN bus, KNX bus, RS485, TTL / serial, proprietary radio connection to 433/868/915 MHz). Range problems can be circumvented because each device according to the invention increases the range of the overall system (repeater function).

The connection to the outside world (Internet, absent users) can be established via the integrated W-LAN interface, if necessary also LAN connection. If no local Internet access is available, further development of the device via a GSM / 2G / 3G / LTE wireless module can connect directly to the Internet or end user.

To improve the detection of environmental data, such as temperature, humidity or air quality, the device has an active speed-controlled integrated fan, which can supply the integrated sensors with a different amount of fresh ambient air depending on the requirement profile. This causes the sensors to react. e.g. Gas sensors, faster to changes in the environment and it is a better thermal decoupling of the sensors to integrated components with self-heating achieved (processor, gas sensors with heating, power supply).

The main concerns of customers against the use of building automation technology are reliability and computer security, in terms of protection against external attacks on the system.

To increase computer security or as protection against hacker attacks, the device according to the invention relies on open source software. Vulnerabilities and faults in open source software are detected faster than in proprietary variants. Through the use of open source software, the device can also be fitted more quickly into individual automation applications.

At the same time, the device is thus able to integrate into many existing, even proprietary, systems to which free software modules exist (e.g., Homematic, Somfy, etc.).

The further benefits of using open source software should not be discussed here.

To increase the technical reliability, the control unit is divided into a main computing unit and at least one additional secondary processing unit in the device according to the invention.

Where the main computing unit is characterized by the fact that it uses a multi-tasking operating system, has significantly more computing power than a secondary processing unit and more complex functions (graphical user interface, web server, evaluation of the data of the camera module, etc.) can provide.

The secondary arithmetic unit is characterized by the fact that in it elementary control tasks can be outsourced and can also take over alone when the main unit is out of operation. Elementary control tasks are tasks which can occur locally and can be solved with the integrated sensors and actuators, e.g. Individual room temperature control, light switch, CO-Warner.

8-, 16-, and 32-bit microcontrollers having a non-volatile memory for storing program code and data, e.g. AVR microcontroller: Atmega32u4, AT90USB *, AT XMEGA or even 32-bit ATSAMD microcontroller.

The secondary units are interconnected to the main computing unit via an internal network (e.g., I2C, USB, SPI, etc.). The sensors can be queried by all computing units via the bus system.

The main processing unit has the sovereignty over the secondary units and is able to change the program code of the secondary processing units during operation. Thus, the secondary processing units can be adapted to all current conditions and control tasks.

By using 2 separate systems in the device, a higher overall stability can be achieved. The computing units may monitor each other and, in the event of failure, alert the end user or attempt to restore an operational condition, e.g. by reset release. For this purpose, the reset pins of the built-in arithmetic units are each connected to a GPIO pin of the other arithmetic unit.

A separate power supply for the separate computing units can be implemented in the device. The secondary arithmetic units have a much lower power consumption compared to the main unit and can be supplied separately by a capacitor power supply, for example.

The device according to the invention is modular and has a flexible range of functions. Thus, e.g. In rooms with increased need for privacy camera modules and microphones undesirable. The device can be adapted to these different needs.

The device according to the invention also permits the variable equipping with different radio modules, thus the device can be specifically made compatible for certain radio systems (even proprietary radio systems).

The device consists of a flush-mounted part and surface-mounted part, wherein both components can be electrically connected via a pin header and mechanically via a plastic frame connection.

In the flush-mounted area of the device, a power supply, the switching actuators and at least one current measuring device are integrated. Likewise, the flush-mounted area provides an interface to supply, data and control lines.

Direct switching actuators are, for example: relays, phase section dimmers, phase control dimmers and thyristor actuators.

The device can optionally be equipped with various flush-mounted components. Depending on the application, different actuators can be installed to control connected devices.

The invention can therefore also be used in typical AC environments (110v - 240v 50 / 60Hz) and DC environments (stand-alone systems, 24V heaters, automotive, boats 6v - 80v, off-grid environments) by selecting the appropriate power supply.

At the same time, the separate flush-mounted area also allows adaptation to the required smart-metering tasks.

Typically, AC power supply lines are laid in space in the ring.

The current measuring device can therefore be used as a measuring device for the total power consumption of the "ring" or for measuring a device connected to an actuator.

• - Speed-controlled fan, primarily for thermal decoupling of the integrated sensors and cooling of the device

Another advantage and component of the device according to the invention is a data output for connecting serially interconnected, controllable in color and brightness, multi-color bulbs. The connected bulbs can assume different colors and brightnesses.

As a result, different color moods and lighting intensities can be created in different areas of a room.

The number of connected bulbs is variable, so that different sized rooms can be illuminated. Typical bulbs are RGB LED.

A further advantageous embodiment of the device according to the invention is the integration of an infrared sensor (IR thermopile) called IRS, which is integrated and aligned in the upper housing part to detect the heat radiation in the center of the room can. The measurement of IR radiation in the room promises advantages, better to determine the "perceived temperature" of people in the room and to be able to regulate the heating more precisely as needed.

In combination with the integrated motion detector can thereby also predict the approach of a person to the device according to the invention.

When approaching a person to the device, the heat radiation of the person continuously influences the infrared sensor IRS more.

The approximation of approximation allows the device to prepare for future user input, e.g. On the display screen, you can see controls that are otherwise hidden to make spatial information clearer.

The infrared sensor IRS can optionally also be a thermal imaging camera.
