Description

TITLE

HVAC system and method for commissioning a field device of a HVAC system

TECHNICAL FIELD

The application relates to a HVAC system for configuring data of a plurality of field devices of the HVAC system, wherein the HVAC system comprises: a plurality of field devices; a commissioning device comprising a user interface and a communication interface for receiving data from a first field device of the plurality of field devices. Furthermore, the application relates to a method for commissioning a field device of a HVAC system, wherein the method comprises the following steps: (a) Establishing a connection between a commissioning device and a first field device; (b) transmitting a set of reference data from the first field device to the commissioning device via the connection established in step (a).

BACKGROUND OF THE INVENTION

In the field of heating, ventilation and air-conditioning systems (HVAC) of buildings, in particular residential buildings, office buildings, commercial buildings and industrial buildings, automatic fluid flow measurement and regulation becomes more and more important. These HVAC systems comprise a plurality of field devices, e.g. actuators, sensors, room sensors, room operating units (ROUs), thermostats, valves, fans, pumps, or combinations thereof.

A particular challenge is the commissioning, setting of operation parameters and adjustment of components of electronically programmable components of a HVAC system, since HVAC systems may be quite complex. While the manufacturer of a field device may pre-install configuration parameters of a field device that are characteristic for a certain model, other setting parameters may depend on the installation site, user preferences, weather conditions, environmental conditions, etc, where the field device is to be installed.

For commissioning the field devices (sensors, valves, etc.) of a HVAC system, system integrators have manual configuration tools (PC, mobile devices, cloud-based devices, etc,). For example, configuration data of a plurality of field devices may be downloaded from a remote/local server or a cloud server to a mobile device and then be transferred from the mobile device to a field device using a wire connection or a wireless connection. Data of a particular field device may be retrieved by the mobile device using an app installed in the mobile device. Just the same, programming of the components of the system may be time-consuming and cause considerable effort due to the obvious complexity. Furthermore, when programming individual values in a plurality of components certain features offered by the system may not be used and errors may occur easily.

OBJECT OF THE INVENTION

It is an object of the invention to provide a HVAC system and a method for configuring and setting data of a plurality of field devices of a HVAC system that reduce effort and avoid possible errors when programming device settings.

SUMMARY OF THE INVENTION

This object is attained by providing a HVAC system for commissioning data of a plurality of field devices of a HVAC system according to claim 1, a method for commissioning a field device of a HVAC system according to claim 6, a field device according to claim 16, a computer program according to claim 17, and a data medium according to claim 18. The dependent claims refer to features of preferred embodiments of the invention.

A HVAC system for commissioning data of a plurality of field devices of the HVAC system according to the invention comprises: a plurality of field devices; a commissioning device comprising a user interface and a communication interface for receiving data from a first field device of the plurality of field devices and for transmitting data entered by a user to a second field device of the plurality of field devices, wherein the commissioning device is configured for displaying a reference set of configuration data and/or setting data received from the first field device of the plurality of field devices, and transmitting a target set of configuration data and/or setting data, wherein the target set of configuration data and/or setting data is based on the reference set of configuration data and/or setting data and comprises at least one data element not in common with the reference set of configuration data and/or setting data.

The HVAC system and the corresponding method provide a workflow for use in the HVAC system for commissioning field devices (particularly sensors and actuators, but also thermostats, ROUs, valves, fans, pumps, or combinations thereof) in the HVAC system. Using the workflow helps reduce the effort and avoid possible errors when entering device data and configuration data. This is accomplished by copying a set of configuration data from a first field device to one or more other field devices. The field devices may be similar or identical. Therefore, a selection of data (comprising one or more data elements) of the complete set of data (reference data set) may be transferred without being altered. The remaining data (subset comprising one or more data elements) may be adapted to the HVAC system and the second field device, respectively. The subset of data may be one or a plurality (two or more) of data elements, i.e. the second field device receives target data composed of data of the set of reference data which have not been altered and data of a subset of data which may or may not have been altered. The target set of data may comprise at least one altered data element, but it may, in a preferred embodiment, comprise at least the subset of data, or, in another preferred embodiment, it may comprise the subset of data and the remaining data of the reference set of data. The target set of data is transferred to the second field device.

A data element may comprise or represent one or more values, parameters, designations, information (e.g. location, type of field device), or any other content or characteristic referring to a field device and the HVAC system, respectively.

Particularly, the invention relates to a HVAC system for commissioning data of a plurality of room operating units (ROUs) of the HVAC system comprising: a plurality of room operating units; a commissioning device comprising a user interface and a communication interface for receiving data from a first room operating unit of the plurality of room operating units and for transmitting data entered by a user to a second room operating unit of the plurality of room operating units, wherein the commissioning device is configured for displaying a reference set of configuration data and/or setting data received from the first room operating unit of the plurality of room operating units, and transmitting a target set of configuration data and/or setting data, wherein the target set of configuration data and/or setting data is based on the reference set of configuration data and/or setting data and comprises at least one data element not in common with the reference set of configuration data and/or setting data.

In other words: the field devices are particularly ROUs.

The target set of configuration data and/or setting data may comprise at least one data element of the reference set of data which has not been altered, and at least one data element of a subset of the reference data which has been altered via a user interface of the communication device. Particularly, the subset of data includes data elements that may be altered, but the user may select which of the data of the subset of data he would like to alter and which of the data remains unchanged, i.e. the data elements of the subset may be changed selectively.

Furthermore, at least one data element is manually altered via a user interface of the commissioning device. Particularly, the data elements of the subset that are changed via the user interface are changed manually.

The commissioning device may be any particular mobile device having at least a CPU, a memory and a short-range communication interface, e.g. a smartphone, a mobile phone, a laptop, a tablet, etc. Furthermore, the commissioning device may comprise a first long-range communication interface for connecting to a server.

In this invention short-range communication interfaces provide one-way or bidirectional communication (including transfer of data and/or information) as soon as the commissioning device approaches the field device to a certain degree or is placed in a position and/or adjusted to be able to communicate with the short-range communication interface of the field device. It is preferred that short-range communication is wireless. In this context, short-range communication may include technologies and standards like Bluetooth, Wireless LAN (WLAN), Bluetooth low-energy (BLE), Thread, Ultra-Wide Band (UWB) and/or Zigbee, Radio Frequency Identification (RFID), Near Field Communication (NFC).

Long-range communication may include Bluetooth technology, UWB, Thread and/or Zigbee, without or via Gateways, WLAN, wire connection (LAN), mobile communications technology (Wide Area Network) communication (such as GSM, LTE, 3G, 4G or 5G mobile communication), Low-Power Wide Area Network communication (such as Narrowband Internet of Things NB-IoT, Long Range LoRa/ LoRaWAN, SigFox, or Long-Term Evolution Category Ml LTECatMl), or a combination of any transmission technologies. Long-range communication in the context of the invention means that there is no necessity that a data server is in any proximity to the mobile communication device.

The reference set of data and/or the subset of data may comprise configuration parameters of a field device that are characteristic for a certain model, and setting parameters depending on the project, installation site, user preferences, weather conditions, environmental conditions, etc. Particularly, the reference set of data may include one or more of application data, CO2 indicator data, system settings data, communication settings data, location data (data 1), enable/disable (data 2), threshold green-yellow (data 3), threshold yellow-red (data 4) and MP address (data 5). In a preferred embodiment of the invention the communication interface of the commissioning device is configured for establishing a short-range connection between the commissioning device and a communication interface of any one of the plurality of field devices.

The inventive method for commissioning a field device of a HVAC system, particularly of a HVAC system as described in this application, comprises the following steps: a) Establishing a connection between a commissioning device and a first field device of a plurality of field devices; b) Transmitting a reference set of data from the first field device to the commissioning device via the connection established in step (a); c) Composing a target set of data based on the reference set of configuration data and/or setting data and comprises at least one data element not in common with the reference set of configuration data and/or setting data; and d) Transmitting the target set of data from the commissioning device to a second field device of the plurality of field devices.

The method and workflow, respectively, may offer a possibility to modify device specific data before writing configuration data and/or setting data to another field device. The data that is altered by a user before transferring it to the other field device may e.g. be highlighted or have any kind of other indicator or mark shown on a display of the commissioning device. In this way the altered data is marked to indicate that it has changed.

In particular, the inventive method for commissioning a field device of a HVAC system, particularly of a HVAC system as described in this application, comprises the following steps: a) Establishing a connection between a commissioning device and a first room operating unit (ROU) of a plurality of room operating units; b) Transmitting a reference set of data from the first room operating unit to the commissioning device via the connection established in step (a); c) Composing a target set of data based on the reference set of configuration data and/or setting data and comprises at least one data element not in common with the reference set of configuration data and/or setting data; and d) Transmitting the target set of data from the commissioning device to a second room operating unit of the plurality of room operating units.

In other words: the field devices are particularly ROUs. Step (d) may comprise establishing a short-range connection between the commissioning device and a second field device of the plurality of field devices. Usually, the connections according to steps (a) and (d) are data connections.

Step (b) may comprise displaying the reference set of data received by the commissioning device on a display of the commissioning device.

Step (c) may comprise displaying the target set of data composed in the commissioning device on a display of the commissioning device. It is preferred that before writing the target data to another field device a summary page indicates all data that will be written to the target field device on the display.

Step (c) may comprise marking the altered reference data among the target data.

Step (d) may comprise checking the compatibility of the first field device and the second field device before transmitting the set of target data.

After termination of method step (d) method steps (c) and (d) may be repeated N times (N being an integer) for a number N of field devices. In this way, data (e.g. parameters, settings) that are the same may be multiplied to a plurality of field devices and just the data that differ between field devices have to be altered and entered in the set of corresponding target data. For commissioning a field device a first group of data selected from the reference set is not altered, whereas a second group (subset) is altered by newly configuring, setting and/or adjusting programmable data of the field device. After having written the data to a second field device the user may be prompted if he would like to copy the data to another device. If yes, a summary page of the previously written data may be displayed. Data which differs from the configuration and/or setting data of the first device may be highlighted. The method could also be described as providing a copy, modify, and paste functionality for configuration data transferred via a wired/wireless connection from one field device to any other field devices using a mobile/portable device.

There may be further functionalities implemented, for example allowing to return to the reference configuration, even after altering the data multiple times.

In another embodiment of the invention the reference set of data may be saved or stored in a memory of the commissioning device, so the workflow could be interrupted and resumed any time. Furthermore, the user may return to the beginning of the workflow.

In a particular embodiment of the invention the method may comprise an auto-increment function for incrementing particular parameters of the set of reference data before proceeding to step (d). The particular parameters may be e.g. identification numbers (IDs) and/or busaddresses of field devices of a HVAC system.

Step (b) may comprise storing the reference set of data in a memory of the commissioning device. The stored data may be used for being transferred to a number of other field devices.

Particularly, the reference set of data may include one or more of application data, CO2 indicator data, system settings data, communication settings data, location data (data 1), enable/disable (data 2), threshold green-yellow (data 3), threshold yellow-red (data 4) and MP address (data 5).

The invention relates to any combination of features described in this application.

DESCRIPTION OF PREFERRED EMBODIMENTS OF THE INVENTION

Fig. 1 illustrates an embodiment of a HVAC system 1 having a HVAC control /commissioning system for setting data in a plurality of field devices 2, 3 which are components of the HVAC system 1. In the embodiment, field devices 2, 3 comprise at least a mechanical and/or sensory part 20, 30, respectively, including, for example, an actuator, a sensor, a thermostat, a fan, a compressor, a pump, a room operating unit (ROU), or any other device for managing the operation of the HVAC system 1. Particularly, the field devices in this embodiment are room operating units (ROUs). Furthermore, the field devices 2, 3 have a control device 21, 31, respectively, which may include a central processing unit (CPU) 210, 310 and a memory 211, 311, respectively, e.g. an EPROM (erasable programmable read-only memory), EEPROM (electrically erasable programmable read-only memory) or a flash memory. The memory 211, 311 may store configuration data (i.e. equipment attributes characteristic for a particular model of the field device 2, 3) and/or setting data (i.e. attributes characteristic for a particular HVAC installation, for particular environmental conditions or for particular user preferences).

Furthermore, the control devices 21, 31 include at least a first short-range wireless communication interface 212, 312, respectively, for example near-field communication (NFC) devices. In this example, the NFC devices are based on RFID technology and provide contactless short-range data transfer between at least two NFC devices. The NFC transponder (or NFC chip) may be an active transponder (NFC module) or a passive transponder (NFC transponder). Instead of near-field communication, any other wired connection and wireless connection could be used, provided a plurality of field devices could be addressed separately and successively.

Furthermore, the HVAC system 1 includes a commissioning device 4 which may be a mobile communication device, e.g. a smartphone, a mobile phone, a tablet, a laptop, etc. The commissioning device 4 comprises a CPU 40, a memory 41, a second short-range wireless communication interface 42 and a first long-range communication interface 43. The second short-range wireless communication interface 42 may be a near field communication (NFC) device. Instead of near-field communication, any other wired connection and wireless connection could be used, provided a plurality of field devices could be addressed separately and successively by the commissioning device 4. Furthermore, the commissioning device 4 has a display and/or user interface unit 44, e.g. a touchscreen. The display is provided for showing a set of configuration and/or setting data (parameters) of the first field device 2, e.g. in the form of a table. A subset of these data may be altered by the user before commissioning and/or configuring the next (second) field device 3. The parameters of the subset may be indicated, e.g. highlighted on the display. The user interface (e.g. touchscreen, keyboard, keypad) is provided for entering and altering, respectively, data (elements) of the subset of data selectively.

The system 1 may comprise further components, e.g. further commissioning devices or further field devices not shown in Fig. 1.

The short-range connection could be a powerless connection which is characterized in that the short-range communication interface 212, 312 of a field device may be powered by the commissioning device 4, particularly through harvesting energy derived from an electromagnetic field produced by the commissioning device 4. Therefore, in this example, the field device could be commissioned without providing a separate power supply.

The present invention particularly deals with efficient commissioning and/or setting configuration data and/or setting data of a plurality of field devices 2, 3 via the (mobile) commissioning device 4. Using the inventive HVAC system facilitates comfortable set-up and operation of field devices of a HVAC system and helps to reduce erroneous settings.

The first long-range communication interface 43 of the commissioning device 4 may provide data exchange between the interface 43 and a second long-range communication interface 50 via a wire connection, a wireless connection or a combination of both. The long-range connection connects the mobile commissioning device 4 to a data server 5 like a website, a cloud server, a server of a provider, etc. Data and programs as well as commissioning data for various types of field devices may be downloadable from the server 5 and possibly stored in the memory 41 of commissioning device 4.

On the other hand, in the solution using a server 5 (data server, cloud server, etc.) uplink data transfer and/or upload of data to the server 5 and possible synchronisation with a digital twin may be provided. For example, changes to one or more commissioning data and/or settings data may be uploaded to the cloud and optionally synchronised with data related to a digital twin.

Fig. 2 is a flow chart 200 illustrating a method according to the invention.

In a first step 210 a commissioning device establishes a connection with a first field device. In a next step 220, reference data is received from the first field device. In other words, the first field device transmits a reference set of data to the commissioning device 4. In a step 230 a subset of reference data from the first field device is defined. The subset is characterized in that it includes data that is alterable and adjustable, respectively, to a second field device to be commissioned.

In a next step 240 target data intended for the second field device is composed on the commissioning device 4. The composed target data may comprise altered and non-altered data of the subset as well as remaining (non-altered) reference data which does not belong to the data of the subset.

After step 240 there may be an optional step 245 of requesting the user to validate the data composed in step 240 before writing the data to the target device. In a next step 250 target data is transferred to the second field device. The process may be continued for commissioning further field devices by either repeating steps 230, 240 and 250, or steps 240 and/or 250.

The skilled person will appreciate that one or more of the steps described above in connection with Fig. 2 may also involve displaying the data on the display/interface 44 of the commissioning device 4. For instance, defining the subset of reference data in step 230 and/or composing the target data for the second device in step 240 may include displaying the corresponding data on the display/interface 44. Similarly, the step of requesting the user to validate the data in step 245 may include displaying a summary of the target data to be written to the second device on the display/interface 44 of the commissioning device 4 so that the user can easily and quickly review the data before writing.

Figs. 3a-3c show a workflow according to the invention. The workflow may particularly be used in combination with a system 1 according to Fig. 1.

After starting an assistant application program (app) installed or loaded in the commissioning device 4, in a first step SI of the workflow a screen “scan device” is displayed and the mobile commissioning device 4 is used as a reader. The NFC device 42 of the commissioning device 4 is moved into close proximity d (d<D, wherein D is a minimum distance for the effectiveness of short-range data transfer) of the NFC transponder 212 of a first (reference) field device 2. Using NFC technology is just an example. Depending on the connection settings of a user, any other short-range communication could be used, e.g. ZIP (Zone Information Protocol).

In a step S2 of the workflow the display/interface 44 of the commissioning device 4 displays an overview of the read data and an activation symbol (e.g. an icon or start button). Data 1 to data 6 of the overview may comprise designations, parameters, settings and values like type of device (product code), voltage source, temperature, humidity, dew point temperature, etc.

The user may trigger a process represented by the symbol by actuating (e.g. clicking) the activation symbol. In step S2 the user may initiate performance of the following writing steps S3-S7 of the workflow. When the start of the writing steps has been initiated by the user, the workflow proceeds to step S3 designated “advanced operation”.

In step S3 the user is invited to click on a symbol “write to another device”.

In step S4 a screen “write to another device” is shown on a display of the user interface 44. In this screen the user has a choice to select configuration and/or setting data that need to be copied to the second device. The selected data can be copied without alteration (e.g. data that are always the same) or with alteration (e.g. location data). Unselected data would not be written to the target device and they will remain unchanged in the target device. There are groups of settings, e.g. “Application”, “CO2 Indicator”, "System” and "Communication” settings. Collectively, the groups may contain individual settings data 1 to data 5. For instance, data 1 to data 5 may be settings like “location” (data 1), “enable/disable” (data 2), “threshold greenyellow” (data 3), “threshold yellow-red” (data 4) and “MP address” (data 5). In the example shown in Fig. 3b, data 1, data 2, data 3 and data 5 have been selected as indicated by the checkmark appearing on the left-hand side of the display/interface. Settings can be selected group wise (e.g. “Application”) or individually (e.g. data 2 and data 3 listed under “CO2 Indicator”). Selecting all the data in a particular group is done by checking the box under the appropriate settings header (see e.g. checkbox appearing to the left of the "Application" settings header in Fig.3b) and means that data/settings can be 'bulk' selected by group. This feature is enabled through linking the data with each other. For instance, the data to be linked may be stored and organised in a data structure, e.g. array, linked list, stack, queue, graph, hash table or tree. Furthermore, the user may edit the value of the data that are device specific or unique, e.g. name, location or address.

An “undo” button will reset all changes and revert them to the settings of the reference device 2. The “undo” button will only appear when at least one setting is different from the reference device. Clicking a “back” button will return the process to a previous step or end it.

In step S5 a summary of all the data that will be written to the next field device 3 is displayed in the “write to another device” screen. The user may make device specific changes if necessary. Changes made relative to the reference field device 2 may be specifically marked, e.g. in colour. Afterwards, the next step of triggering the writing may be initiated by the user.

In step S6 of the workflow a mobile commissioning device 4 is used as a write and transmission device. The screen displays “write configuration” and instructs the user to place the mobile commissioning device 4 near the target field device 3. When the NFC (or any other short-range communication, e.g. ZIP) device 42 of the commissioning device 4 has been moved into close proximity d of the NFC chip 312 of a second (target) field device 3, the data from the commissioning device 4 is transmitted to the second field device 3 for commissioning, setting up and updating the setup, respectively, of the second field device 3. In step S7 a warning message is displayed and the workflow returns to the “write configuration” screen if the second field device 3 is not compatible with the first field device 2. For example, the warning message may be displayed if incompatible versions of the device are involved in the read/write operation. Said incompatibility may arise from a hardware perspective, e.g. different versions of otherwise the same device type used in the read/write operation. Alternatively, the incompatibility may arise from a software perspective, e.g. different versions of software installed on the devices used in the read/write operation. In some embodiments, a warning message is displayed if the devices involved in the read/write operation have a different device status.

On the other hand, if the transmission has been successfully accomplished, a respective message is displayed on the screen and a screen “write to another device” is displayed. The user may either terminate the transmission workflow at this point and the commissioning device 4 will return to the “overview” page of the reference field device 2. Alternatively, the user may initiate and repeat the writing process with another third (target) field device by returning to step S3. Step S8 illustrated in Fig. 2c corresponds to step S4 and further steps may be repeated in order to commission and setup, respectively, the third field device. Before repeating the writing step any of the data/settings written to the first target device may be modified before writing to the second target device.

Fig. 4 shows a commissioning device 4 according to the invention. The commissioning device 4 may have an auto increment functionality displayed on the display screen of the user interface 44. Some parameters or values are incremented when written to another device. For example, an identification number (ID) and/or a bus address could be automatically incremented. Automatic incrementing could be provided as an option or feature of a commissioning device 4 and method according to an aspect of the invention as shown in Fig. 3. The functionality may be activated or de-activated.
