Description

Field of the Invention

[0001] The present invention relates to a control device, in particular for building automation, for controlling one or more field devices, which are connected to the control device in a data technology manner via a communication network, in particular via a fieldbus. Furthermore, the present invention relates to a method for transmitting data to a control device for controlling one or more field devices, which are connected to the control device in a data technology manner via a communication network, in particular via a fieldbus. Background Art

[0002] The commissioning of building automation systems for heating, ventilation, air conditioning, etc. requires the efficient loading of large amounts of data (such as application software, parameterization data, text libraries, UI graphics for user interfaces) onto the control devices (such as controllers, automation devices) required therefor. Furthermore, during the commissioning or maintenance of the control devices, updates of the firmware (for bug fixes, security updates or function extensions) are often required.

[0003] At the time of commissioning a control device (such as an IP-based controller) for building automation that communicates via the Internet protocol (such as IPv4, IPv6), the IP building network (backbone) is often not yet ready for operation and the efficient loading of large amounts of data via the backbone is therefore not possible.

[0004] The loading of large amounts of data onto the control device using a "non-IP building network" (such as a BACnet MSTP backbone) is generally very inefficient due to the low transmission capacity and will take too long for commissioning (such as several hours for firmware updates).

[0005] In principle, large amounts of data can be efficiently loaded onto the controller via the local USB interface on the controller (control device). However, the controllers for automation systems are often installed in inaccessible locations (such as in false ceilings, in window panels or in false floors), and it is difficult and time-consuming to arrange a USB cable between the tool and the controller. Furthermore, the length of the USB cable is limited to a few meters. Summary of the Invention

[0006] Accordingly, it is an object of the present invention to provide a control device onto which large amounts of data can be efficiently loaded. Furthermore, it is an object of the present invention to provide a method for efficiently loading large amounts of data onto a control device, in particular for building automation.

[0007] This task is solved by a control device (e.g., a controller, an automation device, an Automation Device), where the control device includes a wireless service interface (a Wireless-Service interface, e.g., a WiFi interface, a WLAN), and the control device is configured to receive a radio signal (FSIG) generated by a device (e.g., a mobile communication terminal device, a smartphone, or a wireless communication field device) via a suitable radio connection (e.g., Thread, ZigBee, Bluetooth, NFC) through another wireless interface and activate the wireless service interface (e.g., WLAN) based on this radio signal. Advantageously, the control device can in particular be used or configured for building automation to control one or more field devices (e.g., actuators, sensors), and the field devices are connected to the control device in a data technology manner through a communication network, in particular through a fieldbus (e.g., a KNX bus).

[0008] The radio signal for activating the service interface sent by a device (e.g., a smartphone, a tablet, or a wireless communication field device) to the control device can be, for example, via the NFC (Near Field Communication) protocol, via the Bluetooth protocol, via the Thread protocol, or the ZigBee protocol.

[0009] Through this simple and clear remote activation of the local wireless service interface, for example, service technicians or facility managers can very quickly and effectively start downloading the required data to the corresponding controller. The building backbone network (i.e., the backbone network in the building, e.g., an IP network) does not have to be ready to run for this. The time-consuming positioning of the controller in an inaccessible location and the removal of false ceilings, window panels, or false floors for placing a USB cable on the controller or for operating the service button on the controller (control device) are eliminated. The service use during continuous operation is significantly simplified and accelerated because data can be loaded onto the controller (control device) at high speed via the wireless service interface. The execution of the commissioning and service work of the controller (e.g., maintenance, patch installation, firmware update) becomes significantly faster and more reliable.

[0010] A first advantageous design of the present invention is that the control device is configured to simulate the operation of a service button local to the control device (SG) by the received radio signal and thereby activate the wireless service interface.

[0011] When the control device receives a corresponding radio signal from a device on a corresponding radio interface of the control device (e.g., a radio interface for the NFC, Bluetooth, Thread, or ZigBee protocol), the operation of a service button located locally at the control device is simulated by logic (advantageously by corresponding software) stored in the control device, and thereby the wireless service interface (e.g., a WLAN interface) of the control device (controller) is activated. The controller, i.e., the control device, converts the received signal in such a way that the controller simulates the operation of the local service button on the control device as if someone had operated the service button locally at the controller. After receiving the corresponding radio signal, the wireless service interface of the control device is activated.

[0012] Another advantageous design of the present invention is that, after activating the wireless service interface, the control device is configured to receive data (e.g., firmware, firmware updates) and / or send data (e.g., configurations, service protocols) via the wireless service interface. Debugging and service use during continuous operation are significantly simplified and accelerated because data can be loaded onto the control device at high speed via the wireless service interface.

[0013] Data can be transferred from a correspondingly configured tool to the control device or received by the control device. The tool (computer-aided tool) can be, for example, a mobile communication terminal device, a smartphone, a tablet computer, or a personal computer (PC), which is, for example, equipped with corresponding software for engineering tools and / or debugging tools and / or configuration tools. The tool and the device can be operated by different users or the same user. The device and the tool can be physically different devices. However, the device and the tool can also be the same.

[0014] Another advantageous design of the present invention is that the control device is configured to automatically deactivate the wireless service interface after receiving or sending data. By automatically turning off the wireless service interface by means of a timeout, the manual deactivation by a service technician after the end of service work (which is often forgotten) is eliminated.

[0015] Another advantageous design of the present invention is that the wireless service interface is automatically deactivated after a defined period of non-use. By automatically turning off the wireless service interface by means of a timeout, the manual deactivation by a service technician after the end of service work (which is often forgotten) is eliminated.

[0016] Another advantageous design of the present invention is that the device is a correspondingly configured mobile communication terminal device, such as a smartphone, a tablet computer, or a PDA. These devices are commercially common devices that service technicians or debugging technicians usually have. These devices typically include the required hardware and software components or can be equipped with these components.

[0017] Another advantageous design of the present invention is that the device is a wireless communication field device (such as a room device). The wireless field device can communicate with the control device via a corresponding radio interface, for example, via the Thread or ZigBee standard protocol. This radio interface is not the wireless service interface of the control device (such as a WLAN interface). Advantageously, the device, i.e., the wireless field device, is integrated into the communication network for the field devices to be controlled by the control device.

[0018] Another advantageous design of the present invention is that the control device is configured to receive the radio signal generated by the device via a suitable radio connection and deactivate the wireless service interface based on this radio signal. This can be comfortably done through a corresponding operator input.

[0019] Furthermore, this task is solved by a method for transmitting data to a control device (such as a controller, automation device), especially for building automation, where activation is performed via a radio signal generated by a device (such as a mobile communication terminal device (such as a smartphone, tablet) or a wireless communication field device) and sent to the control device, and this radio signal is received by another wireless interface of the control device (SG) (such as via a radio interface for the NFC, Bluetooth, Thread, or ZigBee protocol); and where after the wireless service interface is activated by a tool (such as a commissioning tool, engineering tool, tablet, PC), data is transmitted to the control device via the wireless service interface (such as WLAN) or data is transmitted from the control device to the tool. The radio signal for activating the service interface, sent by a device (such as a smartphone, tablet, or wireless communication field device) to the control device, can be, for example, via the NFC (Near Field Communication) protocol, via the Bluetooth protocol, via the Thread protocol, or via the ZigBee protocol. This method is advantageously used for a control device (such as a controller, automation device) to control one or more field devices, which are connected to the control device in a data technology manner via a communication network, especially via a fieldbus (such as a KNX bus). Thus, a large amount of data can be quickly loaded onto the control device on-site.

[0020] Another advantageous design of the present invention is that the operation of a service button located locally at the control device is simulated by the radio signal received by the control device, and thereby the wireless service interface of the control device is activated. The control device (such as a controller, PLC, SPS) is configured to convert the received service signal so as to simulate the operation of the local service button on the controller as if someone had operated the service button locally at the controller.

[0021] Another advantageous design of the present invention is that after the data transmission, the wireless service interface is automatically deactivated. By automatically turning off the wireless service interface by means of a timeout, the manual deactivation by the service technician after the end of the service work (which is often forgotten) is eliminated.

[0022] Another advantageous design of the present invention is that the wireless service interface is automatically deactivated after a defined period of time when not in use. By automatically turning off the wireless service interface by means of a timeout, the manual deactivation by the service technician after the end of the service work (which is often forgotten) is eliminated.

[0023] Another advantageous design of the present invention is that the wireless service interface of the control device is deactivated via a radio signal generated by the device and sent to the control device. Thus, the WiFi interface of the control device (such as a controller) can not only be turned on by the device (such as a smartphone), but also be manually turned off via another instruction, such as an explicit instruction by the service technician.

[0024] Another advantageous design of the present invention is that the device is a mobile communication terminal device (such as a smartphone, a tablet computer) or a correspondingly configured field device. The mobile communication terminal device belongs to the standard equipment of the service technician.

[0025] Another advantageous design of the present invention is a device for implementing the method according to the present invention. The method according to the present invention can be implemented or updated using commercially available components (COTS, Commercials off the Shelf). Description of the Drawings

[0026] The present invention and its advantageous embodiments are explained by way of the following figures. Here:

[0027] Figure 1 An exemplary communication network with an exemplary control device and a field device is shown, and

[0028] Figure 2 An exemplary flowchart of a method for transmitting data to a control device is shown. Detailed Description

[0029] Figure 1An exemplary communication network KN is shown with an exemplary control device SG. Advantageously, the control device SG is set up to control exemplary field devices FG1 - FG3. The exemplary control device SG can for example be a correspondingly set up controller or an automation device for building automation, for example for controlling or regulating HLK functions (heating, ventilation, air conditioning) in a building. The communication network KN is advantageously a fieldbus or an installation bus (for example a KNX bus system). The field devices FG1 - FG3 are for example actuators (such as drives for awnings or curtains, dimmers, temperature displays, alarm indicators, etc.) or sensors (such as temperature sensors, temperature detectors, motion detectors, presence detectors, dimmer buttons, etc.).

[0030] According to Figure 1 the exemplary control device SG is set up to control one or more field devices FG1 - FG3, wherein the field devices FG1 - FG3 are connected to the control device SG in a data - technological manner via a communication network KN (for example a fieldbus or an installation bus). The control device SG includes a wireless service interface SS (for example a WLAN, WiFi interface), wherein the control device SG is set up to receive radio signals FSIG generated by devices G1, G2 and to activate the wireless service interface SS based on the radio signal FSIG. In the illustration according to Figure 1 the exemplary device G1 is a mobile communication terminal device (such as a smartphone, a tablet), and the exemplary device G2 is a field device set up for wireless communication. The exemplary device G1 communicates with the control device SG via a suitable radio connection KV3. The exemplary device G2 communicates with the control device SG via a suitable radio connection KV2. The radio connections KV2, KV3 can be NFC connections, Bluetooth connections, Thread connections or ZigBee connections. In addition to the service interface SS (for example WLAN), the control device SG includes one or more radio interfaces FS1, FS2 for wireless communication with devices G1, G2.

[0031] Each of the field devices FG1 - FG3, G2 generally includes a respective programming button PT1 - PT4 and / or a respective service pin SP1 - SP4.

[0032] The control device SG is set up to receive and accordingly evaluate radio signals FSIG. The control device SG includes a processor P for executing instructions of a program (especially software (such as an application) or firmware FW). In addition, the control device SG includes one or more storage media M (such as a working memory or a flash memory) for accommodating application software, firmware FW or an operating system.

[0033] Today, controllers or control devices SG are increasingly equipped with local wireless service interfaces SS (such as WiFi, Bluetooth). The wireless service interface SS must be manually activated by a technician for service purposes and advantageously automatically switched off again after a timeout, so that the wireless service interface SS remains deactivated during normal operation (e.g., due to a pre-given building IT management; as an IT security protection measure; or because of the lower current consumption caused by a radio module switched off during normal operation in the controller SG).

[0034] So far, the wireless service interface SS has been activated via a local service button ST on the control device SG (controller). Due to the inaccessible installation location of the control device SG, it is difficult and time-consuming for the operator B to operate the service button ST to activate the wireless service interface SS (e.g., removing the panel, opening the ceiling). Advantageously, the control device SG is thus configured to simulate the operation of the service button ST located locally at the control device SG by receiving a radio signal FSIG and thereby activate the wireless service interface SS. The wireless service interface SS is, for example, a radio interface (such as a WiFi interface).

[0035] In order to receive the radio signal FSIG via an NFC connection, a Bluetooth connection, a Thread connection or a ZigBee connection KV2, KV3, the control device SG is equipped with one or more radio interfaces FS1, FS2.

[0036] After activating the wireless service interface SS, the control device SG is configured to receive data (such as firmware FW and / or application programs) and / or send data via the wireless service interface SS. In the illustration according to Figure 1 , the control device SG is located in the WLAN network of an exemplary router R after activating the wireless service interface SS. After activating the wireless service interface SS, the user B (such as a commissioning engineer or service technician) can load the firmware FW or firmware update onto the control device SG via a tool T (such as a mobile communication terminal device, a smartphone, a tablet, a PC). A communication connection KV1 is established between the tool T (such as an engineering tool or a commissioning tool (Inbetriebnahme-Tool (commissioning tool))) and the control device SG via the WLAN network of the router S.

[0037] An advantageous design of the present invention lies in the control device SG, especially for building automation, for controlling one or more field devices FG1 - FG3, which are connected to the control device SG in a data - technological manner via a communication network KN, especially via a fieldbus, wherein the control device SG includes a wireless service interface SS, and the control device SG is configured to receive radio signals FSIG generated by devices G1, G2 via a suitable radio connection KV2, KV3 through another wireless interface FS1, FS2 and activate the wireless service interface SS based on the radio signal FSIG.

[0038] Advantageously, the control device SG is configured to simulate the operation of a service button ST local to the control device SG by the received radio signal FSIG and thereby activate the wireless service interface SS.

[0039] Advantageously, the control device SG is configured to receive data FW (such as firmware or operating system updates) and / or send data via the wireless service interface SS after activating the wireless service interface SS.

[0040] Advantageously, the control device SG is configured to automatically deactivate the wireless service interface SS after receiving or sending data FW.

[0041] Advantageously, the devices G1, G2 are mobile communication terminal devices (G1) or wireless communication field devices (G2).

[0042] Advantageously, the control device SG is configured to receive radio signals FSIG' generated by devices G1, G2 (such as mobile communication terminal devices or wireless field devices) via a suitable radio connection KV2, KV3 and deactivate the wireless service interface SS (such as a WLAN interface) based on the radio signal FSIG'.

[0043] The device can be a mobile communication terminal device G1 (such as a smartphone, a tablet) or a correspondingly configured field device G2. Advantageously, the corresponding radio connections KV2, KV3 are restricted to the near - field around the mobile communication terminal device G1 or the field device G2. The radio connection KV2, KV3 between the mobile communication terminal device G1 or the field device G2 and the control device SG can be, for example, according to the Bluetooth standard, the Thread standard, the Zigbee standard or according to NFC (Near - Field Communication). The radio connection between the mobile communication terminal or the field device and the control device is carried out through the corresponding chipset and antenna in each of the devices G1, G2 or the control device SG.

[0044] Figure 2 An exemplary flowchart showing a method for transmitting data (such as firmware, firmware updates) to a control device (such as a controller), especially for building automation

[0045] (VS1) The wireless service interface (e.g., WLAN) of the control device is activated via a radio signal FSIG generated by a device (e.g., a mobile communication terminal device, a wireless field device) and sent to the control device, where the radio signal FSIG is received through another wireless interface (e.g., NFC, Blutooth, Zigbee, Thread (IPv6-based network protocol)) of the control device;

[0046] (VS2) After the wireless service interface is activated by a tool T (e.g., an engineering tool or a commissioning tool (Inbetriebnahme-Tool)), data is transmitted to the control device via the wireless service interface or data is transmitted from the control device to the tool. The tool (Werkzeug) can be implemented, for example, on a mobile communication terminal device, a smartphone, a tablet or a PC.

[0047] Advantageously, the operation of a service button local to the control device is simulated by a radio signal received by the control device (e.g., a controller) and thereby the wireless service interface (e.g., WLAN interface) of the control device is activated.

[0048] Advantageously, after the transmission of data (e.g., firmware), the wireless service interface is automatically deactivated. Advantageously, the wireless service interface is automatically deactivated after a defined period of time (timeout) when not in use.

[0049] Advantageously, the wireless service interface of the control device is deactivated via another radio signal (FSIG') generated by a device (e.g., a mobile communication terminal device, a smartphone) and sent to the control device.

[0050] The device can be a mobile communication terminal device (e.g., a smartphone, a tablet) or a correspondingly configured field device. Advantageously, the radio connection is restricted to the near field around the mobile communication terminal device or the field device. The radio connection between the mobile communication terminal device or the field device and the control device can be based on, for example, the Bluetooth standard, the Thread standard, the Zigbee standard or on NFC (Near Field Communication). The radio connection between the mobile communication terminal device or the field device and the control device is made through the respective chipset and antenna in each device or the control device.

[0051] The advantage of the present invention further lies in the apparatus for implementing the method. The method and the apparatus for implementing the method can be implemented using the infrastructure (e.g., a WLAN router) that usually already exists in a building.

[0052] Exemplary scenarios for using the method:

[0053] a. Tool_A (tablet, mobile phone) is used to activate the WiFi service interface on the controller via an alternative, less performant radio interface, such as Bluetooth or NFC.

[0054] b. Tool_B is used to load a large amount of data onto the controller via a high-performance WiFi service interface.

[0055] c. Tool_A and Tool_B can be the same.

[0056] d. The WiFi service interface is activated via Bluetooth or NFC by Tool_A.

[0057] i. The pairing and establishment of an ad hoc connection between Tool_A and the controller via Bluetooth or NFC can be implemented very simply.

[0058] ii. The pairing mechanism for Bluetooth or NFC is well-known.

[0059] iii. With the help of a mobile App, Tool_A sends instructions via Bluetooth or NFC to the controller for remotely activating the local WiFi service interface.

[0060] iv. Alternatively, the explicit manual turning on and off of the local WiFi service interface can be done via corresponding tool instructions from Tool_A via a specific command via Bluetooth or NFC.

[0061] v. The selected controller can be simply identified on Tool_B by recognizing the wireless network (e.g., a new WiFi SSID) and connected to Tool_B.

[0062] vi. Alternatively, Tool_A can reconnect to the controller via the activated WiFi service interface, e.g., by transferring the connection from Bluetooth or NFC to WiFi. The transfer of the connection from Bluetooth or NFC to WiFi can be carried out largely automatically on the tablet or mobile phone.

[0063] e. Instead of the solution via the tablet or mobile phone described in a)..d), the WiFi service interface can be turned on by a wireless (drahtlos) field device (e.g., a room device) via an alternative radio protocol, such as Thread or ZigBee.

[0064] i. The wireless field device must be connected to the controller for this purpose.

[0065] ii. The manual turning on and off of the local WiFi service interface is carried out via corresponding instructions from the field device via Thread or ZigBee.

[0066] f. After the connection between Tool_B (or Tool_A) and the WiFi service interface, the loading of a large amount of data onto the controller (control device) can be carried out very simply and quickly.

[0067] g. The activated WiFi service interface is automatically disconnected when not in use (after timeout).

[0068] h. After the controller is restarted, the WiFi service interface is not turned on (for example, after a successful FW (firmware) download and restart).

[0069] Exemplary advantages of the present invention:

[0070] - On mobile devices such as tablets or mobile phones that are increasingly being used as debugging tools, in addition to WiFi, there are also other wireless interfaces such as Bluetooth and NFC.

[0071] - Due to the widespread use of Bluetooth and NFC in the field of consumer electronics, in addition to the WiFi interface, these radio interfaces can be installed in the controller at very low cost.

[0072] - In addition to traditional wired fieldbus systems, wireless protocols such as Thread are increasingly being used for the integration of IoT peripherals.

[0073] - Commercially available radio chips support the combination of Bluetooth and Thread, making both wireless protocols available at low cost.

[0074] - The present invention increasingly uses radio protocols such as Bluetooth, NFC, Thread, ZigBee in the field of building automation.

[0075] - In addition, the standard interfaces such as WiFi, Bluetooth, NFC existing on mobile devices are optimally utilized.

[0076] - Through this simple and clear remote activation of the local WiFi service interface, service technicians can very quickly, effectively and safely identify (locate) the correct controller for the room and directly start the rapid download of the required data. The building backbone network does not necessarily have to be ready to run for this.

[0077] - Eliminate the time-consuming location of the controller in an inaccessible position and the removal of false ceilings, window panels or false floors for operating service buttons.

[0078] - The service use in continuous operation is significantly simplified and accelerated because data can be loaded via the WiFi service interface at high speed.

[0079] - By automatically turning off the WiFi service interface by means of a timeout, the manual deactivation by the service technician after the end of the service work is cancelled (the manual deactivation is often forgotten).

[0080] - The execution of debugging and service work becomes significantly faster and more reliable.
