Description

Control arrangement for temperature control devices and control methods

The invention relates to a control arrangement for temperature control, ie in particular a control system, and a control method.

Usually, temperature control devices, for example radiators, are controlled centrally via the heating system and locally have a control valve, for example one

so-called thermostatic valve. However, heating control on this basis is usually insufficient, i. an adaptation to the individual needs of a user, in particular a zoning of thermal areas or

Refrigeration areas, in the building room, for example, a living room, a

Office space or the like, hardly possible.

It is therefore the object of the present invention to provide an improved control or regulation or both for temperature control.

To solve this problem, a control method and a

Control arrangement according to the technical teaching of independent claims provided.

It is a basic idea that the HMI device does not communicate directly with the temperature control, but via the communication device. Although the operator has the impression that he controls the temperature control unit directly, for example by displaying the temperature control unit on a display of the HMI device. In fact, however, communication is via the communication device.

Expediently, the configuration data comprise communication data via which or by means of which the temperature control devices can be reached or addressed. The configuration data include, for example, addresses with which the

Temperature control devices are accessible, such as Internet addresses. Furthermore, it is expedient if the configuration data physical characteristics of a respective temperature control device, for example, an average amount of a conventional heat dissipation or heat absorption, location data of the temperature control or the like.

It is advantageously provided that the configuration data comprises an arrangement of at least two tempering devices, in particular of a plurality of temperature control devices, in the building space or a zone of the building space. Thus, it is possible that only those temperature control devices are selectively controllable or controllable via the operating device, which are actually in the building space.

Appropriately, it is provided that the configuration data contain information or a plurality of information about which temperature control devices are assigned to a zone.

Furthermore, it is advantageous part of the configuration data, at which location the temperature control devices are arranged. Thus, it is expediently provided that the configuration data, for example, a local reference of

Temperature control to each other include.

The configuration data furthermore advantageously contain information about

Heat capacity of the building space, to arrange a respective

Temperature control in the building room or the like. Thus, it is possible, for example, to optimally control the temperature of the building space or the zone in the building space.

An expedient variant of the invention provides that the operating device can query at least parts of the configuration data in the communication device, for example, type and size of each to be controlled or regulated

Temperature control unit or other characteristics of a respective temperature control.

Also image data of the temperature control device, for example a JPEG file, which can be displayed on the basis of display means of the HMI device, can be part of the

Form configuration data.

An advantageous concept provides that the communication device control means or control means for controlling, in particular adjustment, or regulation of a Room temperature in the building room or in a zone of the building space based on the at least one tempering comprises or. It is preferred if the operating device is designed to control the control means or control means. Thus, for example, via the operating device a

Room temperature are set, which then set or regulate the control means or control means of the communication device based on the at least one temperature control.

It is preferred if the operating device has one or more sensors, for example a temperature sensor, a light sensor, a brightness sensor or the like. Thus, the operating device may be provided, for example, depending on a use of the building space (light is on or off)

To set the room temperature individually. The temperature sensor makes it possible to detect the temperature in the building room or the zone, so to speak locally, and thus to optimally control or regulate both or both.

The at least one temperature control unit is, for example, a radiator, heat sink or both.

At this point it should be mentioned that an independent invention is formed by the fact that zoning takes place. Thus, it is an expedient and inventive variant if several, for example at least two,

Temperature control units are combined into one zone.

In an operating device according to the invention, different functions can be realized. It is thus possible, for example, for an operating device to control or regulate, as it were, jointly or in each case several or all temperature control devices which are arranged in a building space or a zone. This can be done directly or via the communication device.

In the HMI device, in particular its user interface, is

expediently a key or another operating element is provided with which a switch-on or switch-off process or a program change can be effected by a single keystroke or a single operator action. So, for example, in a premature, so before a usual Switching time taking place leaving the building room or a building as a whole, in which the building space is arranged to be set by such a simple operator action an absence mode. By the

Operator action, i. by operating the control element, the operator switches, for example, from a presence mode (building space or zone is used) to the absence mode. In absence mode, for example, the room temperature is lowered.

Even if a user of the HMI device comes home prematurely, i. if, for example, the heating or cooling is still on after operation or

Absence operation is running, he can switch back to the presence operation of the heating or cooling by a single operation, namely by pressing the actuator or control. Then it will be

for example, raises or lowers a room temperature.

It is also possible that by means of or an actuating element of the

HMI device, a switch from a first control program to a second control program is possible. For example, then

appropriate control program on the device or the communication device selected or activated.

Furthermore, it is advantageous if an automatic mode or a manual mode are limited in time or indefinitely adjustable on the operating device, for example on the basis of a graphical user interface, an operating key or another operating element.

It is preferred if a display of information or error messages or both is provided on the operating device. Appropriately, a plurality of information, including an entire system or part of the system or the control arrangement can be displayed on the operating device. Thus, by means of the communication device or agent, which can form a so-called central component of the control arrangement, information of several temperature control devices, control devices, operating devices or the like can be displayed on a respective control device. Thus, it is possible, for example, a status of a battery of a respective operating device, temperature control device or the like on the Display according to the invention configured control unit. Also one

Connection quality of at least one connection, such as a connection between the HMI device and communication device, communication device and

Temperature control unit or operating unit and temperature control unit can be displayed on the display means of the HMI device, for example on a graphical display.

A variant of the invention can provide that the operating device only one

Has control function. But it is also possible that an operating device or the operating device comprises a control function.

With a control unit intended for one zone, it is possible to use one

Temperature or other climatic setting for an entire zone. Thus, it is possible, for example, a per se automatically provided temperature control or control, which is made for example by the communication device, permanently or for a predetermined

To override time span, so that so to speak, the local control with the

HMI device has priority (override function).

An expedient variant provides that a temperature measurement is possible precisely with this operating device, i. the operating device has a temperature sensor.

In the context of the invention or as an independent invention is also a

To see temperature control, on which a local control unit is arranged. With the operating device, for example, a temperature of the temperature control can be set or pre-selected. It is possible that the operating device controls only the tempering or the temperature control unit, where it is arranged. But it is also a master-slave configuration possible, in which the control unit via wireless or wired or both another temperature control, which is remote from the temperature control, on which the control unit is located, controls.

One or more of the aforementioned operating devices are expediently programmable, for example, based on the communication device, a

Smartphones or the like. The locally arranged on a temperature control unit operating device can be controlled via a higher-level control unit.

It is possible to combine a plurality of locally arranged on a temperature control unit or a temperature control locally associated control panels to a zone or network. These may, so to speak, have a local intelligence, i. inform each other about temperature changes, control commands or the like and so set and / or regulate within a zone, for example, a desired temperature.

A locally arranged on a temperature control unit operating device can

Have automatic mode, i. that it sets, for example, for a predetermined time at the temperature control unit a predetermined temperature or a

Adjusting the temperature for the environment of the temperature control unit based on an adjustment of the temperature adjustment.

It is possible for a temperature control unit to have a communication interface and local intelligence, for example for adjusting the temperature setting device. However, a user interface, such as a display or the like, is not essential. The temperature control unit of this type can be controlled and operated, for example, on the basis of a higher-level control unit associated with a plurality of temperature control units. It is possible to combine temperature control of this type to a zone, wherein the

For example, temperature control units communicate wirelessly with one another in order to set a specific temperature within a zone.

As a control device, a smartphone or a computer can be used, which is equipped with appropriate software. The smartphone or the computer then contributes in particular via the communication device that

Communication device according to the invention one or more of the temperature control.

A preferred variant of the invention provides that the communication device and / or an operating device or the operating device with a bus interface for an automation network, such as a radio interface, a CAN Interface (Controller Area Network), a KNX or EIB interface (European Installation Bus) is provided or has such an interface. In any case, it is advantageous if the communication device can be integrated in a home automation system or can be networked with such an automation system.

Furthermore, it is conceivable that the communication device can be controlled, for example via the Internet. In this way it is possible, even from a distance, for example, from vacation or on a trip, to control the domestic temperature system.

The communication device and / or the operating device preferably has a web interface.

Advantageously, the communication device and / or the operating device comprises a web server.

A preferred embodiment of the invention provides that a local logic is present in a respective temperature control unit or operating device or communication device. It is advantageous, for example, if a respective temperature control unit or operating device or communication device continues to work with existing work data or settings until it receives new instructions. As a result, for example, only changes between the components of the control arrangement must be communicated. Radio traffic is minimized. Energy sources, such as batteries, live longer.

Hereinafter, an embodiment of the invention will be explained with reference to the drawing. Show it:

1 shows a control arrangement with an operating device, a

Communication device and temperature control devices,

Figure 2 shows a first temperature control and

FIG. 3 shows a second temperature control device of the control arrangement according to FIG. 1, FIG. 4 shows a first operating device and

FIG. 5 shows a second operating device of the control arrangement according to FIG. 1.

A control arrangement 10 according to FIG. 1 comprises several

Embodiment variants of a control concept according to the invention, which can also be understood as a control concept or includes such. The control arrangement 10 includes, for example, a plurality of temperature control units 20, 21, 22, 23, each having a local communication interface 48 and further temperature control units 30, 31 and 32, which also have a local control unit 49 in addition to the communication interface 48.

While the temperature control devices 20, 30 are arranged, so to speak, at one location, the temperature control devices 31 and 21 are combined to form a zone Z1 and the temperature control devices 22, 23, 32 are combined to form a zone Z2 or assigned to a zone Z1, Z2. It is possible that all tempering 20-23 and 30-32 in a single building space, for example, a living room or office space, are arranged. But it is also possible that, for example, the zone Z1 in a first

Building space, the zone Z2 are provided in a second building space and the temperature control 20, 30 are arranged in other individual building spaces.

The tempering 20-23 and 30-31 have partially the same or similar components, which are explained below with reference to Figures 2 and 3 by way of example for the temperature control 20-23 on the basis of the temperature control 20 and exemplified for the temperature control 30-32 using the temperature.

A tempering body 40, for example a radiator, can be flowed through by a tempering fluid, for example water. The tempering 40 in the form of a radiator, heat sink or both, is flowed through by the tempering to bring in this way heat in a building room or of the

Dissipate building space. For example, a living space or office can be heated or cooled in this way. The tempering body 40 can absorb heat from the building space and thus cool it. An inflowing tempering fluid 44 and a refluxing temperature control fluid 45 are indicated by arrows. The tempering fluid flow through an inlet port 42 into the tempering 40 and a return port 43 from the

Tempering 40 off.

By means of a temperature adjustment device 41, for example comprising at least one control valve or control valve, it is possible to control or regulate the flow or the quantity of the tempering fluid flowing through the temperature control body 40. For example, the temperature adjuster 41 is on

Return port 41 or inlet port 42 or both arranged. Via a control interface 46 of the temperature setting device 41, for example, a fluidic, in particular hydraulic interface, an electrical

wired or a wireless interface or the like, the temperature adjustment 41 can be controlled so as to the

Adjust the tempering 40 through-flowing amount of the tempering. Via a control connection 41, for example a wireless connection, a

line-connected connection, in particular an electrical connection or a hydraulic connection, the control interface 46 can be controlled.

The wireless interface 48 communicates via the control connection 41 with the control interface 46 of the temperature setting device 41.

The operating device 50 shown in detail in FIG. 4 makes it possible, for example, to set a temperature in zone Z2. Alternatively or additionally, it is possible to individually control one or more of the temperature control devices 22, 23, 32 with the operating device 50.

The operating device 50 communicates via a connection 90 with the

Communication device 70. The connection 90 is a wireless connection, for example via WLAN. The operating device 50 and the communication device 70 each have wireless communication interfaces 53, 73 for the aforementioned wireless communication. The wireless communication interface 73 has, for example, an antenna 74. The operating device 50 has a housing 51 on which controls and

Display elements are provided, such as a display 52, which may also form part of a graphical user interface, and controls 54, 55, e.g. Keys for entering commands. This is definitely one

User interface provided. By way of the keys 54, 55 (alternatively other operating elements could also be provided, for example also operating elements indicated on the display 52), a temperature can be selected, for example. Furthermore, it is possible, via the controls or buttons 54, 55, for example, one or more of the temperature control 22, 23, 32 selectively

head for.

A variant not shown in the drawing can provide that the

Control unit 50, so to speak, individually individually controls each of the temperature control units 22, 23, 32, for example via their respective ones

Communication interface 48.

Advantageously or according to the invention, however, a concept is provided in which this communication is not directly, but indirectly via the

Communication device 70 takes place. If now the operating device 50 so one or more of the temperature control 22, 23, 32 controls, this is done via the

Communication device 70. The communication device 70 thus serves as a gateway for communication between the operating device 50 and the respective temperature control devices 22, 23, 32. The communication device 70 has a separate from the temperature control devices and operating devices housing 71st The communication device 70 may be disposed at a different location or in a different room than the temperature control devices 20-2.

In a memory 80, for example, a database, of the communication device 70, a respective configuration of is arranged in a building space

Temperature control devices stored. For example, zone Z1 is in one

Memory area with configuration data 81, the zone Z2 mapped in a memory area with configuration data 82 in the memory 80. The configuration data 82, 81 contain, for example, the communication addresses of the temperature control body 31, 21 and 22, 23, 32, for example the communication addresses of the communication interfaces 48.

If now the control unit 50 with one or more of the temperature control

22, 23 or 32 wants to communicate, for example, in the zone Z2 a

Specify temperature, for example, checks an executable by a processor 72 program 75 which are associated with the temperature control 20-23 or 30-32 of the zone Z1 and forwards a command received for example via the connection 90 with a control parameter 200 to the temperature control 22,

23, 32 further, e.g. via wireless links 91, 92, 93.

A broader or alternative concept may provide that the program 75 also has control functions or control functions. If, for example, via the operating elements 54, 55, a temperature and / or a time when the temperature is to be set, is specified, determines the program 75 control parameters, for example for the

Temperature adjustment means 41 of a respective temperature control unit 22, 23, 32, to adjust the temperature in accordance with the zone Z2. For example, therefore, the control parameter 200 can be determined and set by the program 75. A corresponding specification for the temperature receives the program 75 from

HMI device 50.

Advantageously, the HMI device 50 still sensors, such as one

Temperature sensor 58 and / or a light sensor 59. Advantageously, it is provided that the operating device 50 transmits sensor values of the sensors 58, 59 via the connection 90 to the communication device 70, so that, for example, the program 75 depends on the light conditions or temperature conditions in the zone Z2 Temperature control devices 22, 23, 32 can control or regulate.

But it should also be mentioned that on board the HMI device 50 an intelligence

can be provided, for example, a regulatory program or

Control program 159 for controlling or controlling the temperature control 22, 23, 32. For this purpose, then the sensors 58, 59 are advantageous. For example, the sensors 58 and 59 can determine values for light and temperature in the zone Z2 on the basis of which the control program or Control program 159 the temperature control 22, 23, 32 controls or regulates accordingly. As already mentioned, this can be done directly (not shown) or in an advantageous or inventive way via the communication device 70. The control program or control program 149 can be executed, for example, by a processor 158 of the operating device 50.

A so-called local unit is shown in zone Z1. It is possible that the temperature control unit 31 represents, as it were, a master for the temperature control unit 21, which is then, so to speak, a slave.

The so-called local control unit 49 of the temperature control unit 31 controls, on the one hand, the temperature control unit 31 itself and, on the other hand, the temperature control unit 21. The

Communication takes place via the wireless communication interfaces 48, in particular via WLAN. Now, for example, a local connection L would be possible, via which the temperature control unit 31 (the local operating unit 49)

Temperature control unit 21 controls. Following the advantageous or inventive concept, however, it is provided that the operating device 49 is not directly connected to the

Temperature control unit 21 communicates, but via the connection 94 with the

Communication device 70, which then determines after checking the data 81 that the associated temperature control unit is the temperature control unit 21 and the

further connection 95 establishes. Thus, the operating device 41 sends

For example, a control parameter 201 via the communication device 70 to the temperature control unit 21.

The temperature control unit 20 has no display and / or no local user interface. However, it may, for example, from the communication device 70 or a

Control unit 60 are controlled.

The operating device 60 has, for example as a user interface, a display 62 and a switching element 64 and a sensor 67. The switching element 64 can be operated via an operating handle, a flexible element 65 and a

Handle member 66 has. The switching element 64 may serve, for example, the HMI device 60 between a 1. Operating mode and a 2.

Switch operating mode. In this way, for example, a switch from an absence mode to a presence mode without further notice possible. Furthermore, it is conceivable that with reference to the switching element 64 a

Switching between an automatic mode and a manual mode is set. In automatic mode, the handle member 66 depends as shown in Figure 5 down, so it is down in front of a housing 61 of the

HMI device 60 from. In a manual mode, on the other hand, the handle element 66 is moved towards the sensor 67, so that it is controlled. For example, the handle member 66 includes a magnet corresponding to the one

magnetically operating sensor 67 controls. When the sensor 67 the

Detected presence of the handle member 66, it is possible, for example, via buttons (not shown) or other controls, but in particular via the designed as a graphical user interface display 62 to control the control unit 60 and give commands, for example, to choose a temperature.

Preferably, a temperature detection is provided, i. one

Temperature sensor, so that the HMI device 60 can detect the temperature in its environment.

With the control unit 60 more temperature control for a living room or building space can be controlled. So it is possible, for example, with the

Control unit 60, the temperature control units 22, 23, 32 of the zone Z2 and / or the

Controlling temperature control units 31, 21 of the zone Z1. The tempering 20 and 30 can be controlled in this way.

One possibility is that the HMI device 60 via its

Communication interface 63 communicates directly with one or more of the aforementioned temperature control. Preferably, however, the communication via the communication device 70 is provided as a gateway. That's how it communicates

Operating unit 60, for example via a connection 98 with the

Communication interface 73. Based on the configuration data in the memory 80, the communication device 70 is now able to establish a connection to the temperature control device to be controlled in each case. For example, the

Temperature control devices 20, 30 are controlled via the connections 97, 96 when the operating device 60 via the connection 98 is a corresponding control command. A smartphone 100 or another computer can also be provided to control one or more of the temperature control devices 20-32 on the basis of the communication device 70. A user interface 102, for example a graphical user interface, which allows a corresponding software module, for example a so-called application or an app, for example, to select a respective temperature control unit 20-32 and / or zone Z1 or Z2 in order to set a temperature there.

At the communication device 70, for example, for controlling via the smartphone 100 web interface 76, in particular a web server, is provided. But it is also possible that the smartphone 100 via its wireless

Communication interface 103 communicates directly with the communication interface 73.

The user interfaces of the operating devices 50, 60, 100, 49 are provided as input means, for example, by a graphical user interface, buttons or the like. The user interfaces comprise as output means

expediently optical displays, for example graphic displays,

Bulbs, LEDs or the like and / or acoustic output means,

For example, a speaker or the like.
