Description

The invention relates to a system for controlling heating, cooling and/or ventilation devices according to the preamble of claim 1.

A wide variety of devices are used to air-condition buildings or individual rooms. As a rule, these devices are heating, cooling and/or ventilation devices or combinations thereof. These devices can be controlled or regulated via operator panels. These operating devices can either be installed directly on the device or designed as remote controls. Communication protocols are stored on the corresponding electronic assemblies in the devices for communication between the operator panels and the individual devices. The functioning of the devices can be regulated or controlled via corresponding interfaces of the assemblies.

In order to control each individual device, the assembly has device-specific connecting elements such as connections, plugs, pins and the like in each device. For example, in the case of a cooling device, a large number of valves have to be activated, while in the case of ventilation devices, for example, motors have to be activated. These device-specific electronic assemblies, which are usually printed circuit boards, are permanently installed in the devices at the factory. At the same time, this module is assigned a specific interface, via which the device can be controlled using a specific communication protocol. The device can then be controlled or regulated with a corresponding operating device using this protocol.

Due to the development of complex building air conditioning concepts and the possibility of networking several devices in private households (smart), individual heating, cooling and/or ventilation devices can also be interconnected to form larger groups. This allows the room climate to be regulated depending on the type and size of the room, the type of use of the room, the time of day, the weather, etc. Since several devices, not just those for air conditioning, are connected or networked with each other, especially in larger buildings, but also in the private sector, it is of outstanding importance that these devices "speak the same language". An essential prerequisite for the functionality of such networks of several devices, in particular from different manufacturers, is the connectivity of the individual devices with each other. If different devices are controlled with different communication protocols, the linking turns out to be problematic or not possible. The consequence of this is that the above-mentioned assemblies of the individual devices have to be modified in such a way that they have correspondingly suitable interfaces. Since it is not usually possible to foresee in the factory which other devices the devices to be manufactured will have to communicate with, this means that modules are installed that later prove to be unsuitable for communication with other devices. An alternative to this would be that the module for communication is only installed in the device later. In any case, a later determination of the interface leads to a considerable additional expenditure in terms of time and money.

Proceeding from this, the object of the present invention is to create a system for controlling heating, cooling and/or ventilation devices, by means of which the connectivity of the aforementioned devices is improved and costs are saved in their production process.

A solution to this problem is described by the features of claim 1. Accordingly, it is intended to create a system for controlling individual heating, cooling and / or ventilation devices and groups thereof, which can be assigned by at least one heating, cooling and / or ventilation device, assembly consisting of two assembly elements, namely one motherboard and an IO board. According to the invention, the motherboard has a large number of different interfaces for communication with other assemblies of other heating, cooling and/or ventilation devices and/or other devices. According to the invention, these interfaces are all interfaces currently in use. This gives the system maximum connectivity to other devices. The IO board of the assembly is specified for the individual heating, cooling or ventilation device. This construction of the module from a universally controllable main board, which has all common or currently used interfaces and a device-specific IO board, optimal connectivity to other devices can be established, while the module is at the same time device-specifically matched. This not only optimizes the connectivity between the devices, but also makes the manufacturing process more efficient. The electronic assembly described here can already be installed in the device during production, regardless of the subsequent application or area of use.

The invention preferably provides that the main circuit board is electrically coupled with a device-specific IO circuit board to form an assembly is pelbar, wherein the coupling takes place by means of at least one pin strip and / or at least one socket strip and the transmission of signals and / or electrical energy between the main board and the IO board is used. Due to this simple mechanical connection of the two circuit boards, the assembly turns out to be particularly easy to produce. Equally, the assembly can also be prepared particularly efficiently, since the two circuit boards can be produced independently of one another and only have to be assembled for installation in the device.

In particular, it is further provided that the motherboard has at least one CAN interface, at least one RS485 interface for the Modbus RTU or BACnet® MSTP protocols, at least one KNX interface, at least one Ethernet interface, at least one USB interface, at least has a Bluetooth® interface and/or at least one WIFI interface for communication with other assemblies of other heating, cooling or ventilation devices and/or other facilities. With these common interfaces, the module for controlling the devices can not only be connected to all common building technology bus systems and or other networks, but also to the usual room control units. The interconnection of several identical devices to form a networked house is also possible via this system with the various interfaces. Thanks to this maximum flexibility with regard to the connectivity of the individual devices, the networking of a large number of devices is also feasible for the layperson.

A further advantageous exemplary embodiment of the present invention can provide that the individual interfaces of the assemblies can be activated or enabled and deactivated, preferably externally. This makes it possible, for example, that all interfaces are initially deactivated. The necessary interfaces can then be activated later by the user when setting up a network of several devices. It is equally conceivable that the necessary interfaces can be activated remotely by a provider or the manufacturer. Accordingly, it is also conceivable that interfaces that are not being used or should no longer be used are switched off by remote control. This configuration of the assemblies with different interfaces that can be controlled allows various functions of the system to be activated or blocked in a targeted manner by a provider.

Furthermore, it can be provided according to the invention that the IO board for controlling the heating, cooling and/or ventilation devices has at least one connector for an analog input, at least one connector for a digital input, at least one connector for a valve and/or has at least one connector for a motor of the heating, cooling or ventilation devices. This device-specific design of the IO board ensures that all components of a device can be controlled via the assembly.

It is preferably also provided that the heating, cooling and/or ventilation devices can be networked with one another via the interfaces of their assemblies and can preferably be combined into groups. The individual devices can only be connected to different groups in any way and flexibly, depending on the application, if the connectivity is optimal. Thanks to this maximum flexibility, complex air conditioning concepts can also be easily implemented in larger buildings. In this way, several heating, cooling and/or ventilation devices can be interconnected to form groups via the individual heating, cooling and/or ventilation device assemblies, independently of predetermined device-specific or system-specific communication protocols.

A method for solving the task mentioned at the outset provides that connections for communication between the heating, cooling and/or ventilation devices among one another and with a bus system for building technology and/or with room control devices are established by means of an, in particular external, activation of interfaces from in the devices installed assemblies are manufactured.

The method according to the invention can further provide that each heating, cooling or ventilation device is assigned at least one assembly with a main circuit board and an IO circuit board according to claim 1 .

• 2 ein zweites Ausführungsbeispiel einer Baugruppe, und
• 3 ein drittes Ausführungsbeispiel einer Baugruppe.

A preferred embodiment of the invention is explained in more detail below with reference to the drawing. In this show:

• 1 a first embodiment of an assembly,
• 2 a second embodiment of an assembly, and
• 3 a third embodiment of an assembly.

At one in the 1 In the highly schematic embodiment, the assembly 10 has two assembly elements, namely a main circuit board 11 and an IO circuit board 12. The main circuit board 11 is connected to the IO circuit board 12 via a connection 13 which is only shown schematically here. This connection 13 can be pins or sockets act. This connection 13 is used both for the power supply and for the exchange of signals between the two circuit boards 11, 12.

In the exemplary embodiment shown here, the IO board 12 has three connections 14 . These connections 14 can be connections, for example with a fan, a valve or a room temperature sensor for controlling the fan. Alternatively, it is conceivable that such connections 14 are designed as analog or digital inputs for connecting a passive analog input (NTC) or an active analog input (0-10V). Two-pin connectors are also available.

A large number of interfaces 15 are assigned to the main circuit board 11 for the regulation or activation of the assembly 10 . These interfaces 15 can be, for example, at least one CAN interface, at least one RS485 interface for the Modbus RTU or BACnet® MSTP protocols, at least one KNX interface, at least one Ethernet interface, at least one USB interface, at least one Act Bluetooth® interface and / or at least one WIFI interface for communication with other assemblies of other heating, cooling or ventilation devices and / or other facilities. At the in the 1 illustrated embodiment, an interface 15 (a CAN interface) is connected to a control unit for the fan. Only for the sake of completeness it should be mentioned that the representation of the assembly 10 in the 1 is schematic and the dimensioning does not correspond to reality. Rather, the assembly 10 is designed in such a way that it can be integrated into the ventilation device as an electronic component.

At the in the 2 In the further exemplary embodiment of the invention illustrated, an assembly 10 is connected to a decentralized ventilation device 16 . While the motherboard 11 with the interfaces 15 is identical to the motherboard 11 of the 1 illustrated embodiment is in the 2 The IO board 17 shown specifies the decentralized ventilation device 16. Here, a large number of connections 14 lead from the IO board 17 to the device 16. A room temperature sensor 18 is also connected to the IO board 17. Just like in the 1 is also in the embodiment according to FIG 2 an operating device 19 is connected to the main circuit board 11 .

Finally, in the 3 a network consisting of a large number of the in 1 illustrated assemblies 10 shown. These individual assemblies 10, consisting of the main board 11 and the IO board 12, are connected to one another via interfaces. One of the modules 10 or a main circuit board 11 is connected to an operating device 19, via which all modules 10 of the network can be operated.

Since all assemblies 10, 20 have a large number of different interfaces (see above), all assemblies 10, 20 can be connected to one another and to other devices (not shown here) in a very flexible manner. Due to the fact that the main circuit board 11 according to the invention has all common interfaces 15, a later application-dependent modification of the assemblies is no longer necessary. As a result, not only is the production of the assemblies 10 particularly efficient, but the connectivity of the devices is also particularly flexible.
