Description

The invention relates to a field device of automation technology, a method for operating such, a computer program product, a computer-readable storage medium and a system of automation technology.

Automation systems such as those used in automation technology, for example, for monitoring and / or controlling a process, usually consist of a variety of system components.

Examples of such plant components are field devices, such as level gauges, mass flowmeters, pressure and temperature measuring devices, etc., which detect the corresponding process variables level, flow, pressure and temperature of the process as sensors.

To influence process variables, field devices are actuators (eg, valves, pumps, etc.) that can be used, for example. B. allow to change the flow of a liquid in a pipe section or the level in a container.

A variety of such field devices is manufactured and sold by the company Endress + Hauser.

Another example of such system components are also process control systems.

Such field devices or system components must not only be put into operation, but also regularly maintained and / or repaired. Usually, this is done by a service technician who runs through the automation equipment and maintains or repairs the field devices according to their needs. A challenge for the service technician at this point is to find or locate the right field device or the correct system component in the automation system in the event of a maintenance or repair. If the service technician has found the corresponding field device or the corresponding system component, it usually also requires further information about the field device or the system component. Typically, these documents, such as manual, older repair reports, spare parts lists and the like. These documents are in digital form today, though not in a single location. Thus, the service technician must seek out all documents in advance even though it is not certain that he actually needs the documents.

It is therefore an object of the invention to indicate a possibility with which the commissioning and / or the maintenance or servicing of field devices or system components is simplified.

The object is achieved by a field device of automation technology for detecting and / or setting a process variable, comprising a marker for determining a position and / or orientation of the field device by an augmented reality application, which marker is set up to emit an optical signal.

The invention will be explained in more detail with reference to the following drawing. It shows:

• 1 : an inventive system of automation technology. The system comprises an automation system 10, which consists of three field devices 1a, 1b, 1c, which are connected to a higher-level unit 9, for example a PLC, by way of example. The field devices 1a, 1b, 1c of the automation system 10 are designed in such a way that they each have an augmented reality-based marker 2, so that they can be tracked, ie tracked, via a corresponding augmented reality application 3. The tracking comprises, in particular, the determination of the position of the respective field device 1a, 1b, 1c in space with the aid of the marker 2 and its orientation. The markers 2 of the individual field devices 1a, 1b, 1c are set up such that they each emit an optical signal having a wavelength. It is in 1 Field device 1 a shown on the left is configured such that a display 6 of field device 1 a is set up such that its backlight serves as the optical signal of marker 2. This in 1 shown in the middle field device 1b is formed such that an optical button or an optical probe element 5, which emits an optical detection signal for detecting a keystroke also emits the optical signal of the marker 2. Preferably, the stylus or the probe element 5 is also set up such that the optical detection signal also serves as the optical signal of the marker 2 at the same time. This in 1 Field device 1c shown on the right is embodied such that it has a luminous means 4, for example in the form of an LED luminaire, via which the optical signal of the marker 2 is emitted.

Here, the optical signals of the individual markers 2 , in particular the markers of the middle and the right field device 1b and 1c be chosen or determined so that they are in a wavelength spectrum not visible to a human. Preferably, the wavelengths of the optical signal are in the infrared spectral range.

About the markers 2 are the field devices 1a . 1b . 1c through a mobile control unit 7 on the appropriate augmented reality application 3 , for example in the form of a so-called app, expires, with regard to their respective geographical position in the automation system 10 determinable and can through the augmented reality application 3 also be visually aligned. In addition, the in 1 illustrated field devices 1a . 1b . 1c arranged such that the optical signal of the respective marker, is modulated so that data with respect to the respective field device 1a . 1b . 1c to which the corresponding marker belongs are transferable. In particular, the field devices 1a . 1b . 1c arranged such that the optical signal is modulated so that identification data, via which the respective field device 1a, 1b, 1c is uniquely identifiable, are transmitted. In addition, the field devices can 1a . 1b . 1c be set up such that the modulation of the optical signal and an authentication code for each field device 1a . 1b . 1c can be transmitted in order to establish an authenticatable wireless data connection with the field device. An example of such an authentication code is a password via which the legitimate establishment of a wireless data connection to the field device can be checked. The wireless data connection can be realized, for example, via a WLAN connection. However, other variants are also conceivable in which the wireless data connection is embodied, for example, in the form of wireless HART, 6LoWPAN or Bluetooth or a variant modified therefrom, in particular Bluetooth Low Energy.

The system of the automation system also includes the mobile operating unit 7 , what a 1 exemplified in the form of augmented reality glasses. The glasses captured, for example. Via a camera, a reality, which results in the field of view of the glasses or an operator wearing the glasses. The field of vision and the captured reality are in 1 exemplified by the dashed lines with the reference numeral 13 shown. On the glasses or the mobile operating device 7 runs an augmented reality application or app 3 , which among other things is set up, an extended reality display 12 on a display 18 to represent the glasses. In 1 is the display 18 the augmented reality glasses 7 exemplified in the upper area.

In the present example, the glasses capture as an example the right field device 1c with the LED marker, which lies in the field of vision of the glasses or the operator. This is in 1 exemplified by the method step S100 indicated. As stated previously, the right field device is 1c set up the optical signal of the marker 2 to be modulated such that identification data, for example the serial number of the field device, are transmitted via the optical signal. The glasses thus capture that of the right field device 1c emitted optical signal and demodulates it so that the identification data are available on the glasses. In the in 1 In the example shown, these steps are indicated by way of example with a dashed arrow and with the method steps S200 and S300. After the identification data of the right field device 1c in the glasses 7 can be available through the glasses as a mobile control unit 7 a wireless data connection 11 to the field device 1c being constructed. This is by the method step S400 in FIG 1 indicated. After making the wireless data connection 11 between the field device 1c and the glasses 7 can be more data between the field device 1c and the glasses 7 be communicated. In this case, the other data relate specifically to the respective field device. In the in 1 example thus shown on the right field device 1c , The further data may, for example, parameter and / or configuration values of the respective field device 1c include. However, the further data can not only relate specifically to the field device, but, for example, also relate to the process to be detected or set by the field device. For example. the further data can also be a measuring and / or a manipulated variable of the corresponding field device 1c include.

The of the field device 1c to the glasses 7 transmitted further data are at least partially by the augmented reality application 3 visualized and with the captured reality 13 superimposed or supplemented and then on the display 18 the glasses 7 displayed. For example, on the display 18 the glasses 7 the detected reality, ie the right field device 1c , be shown and in addition, ie superimposed to a measured value of the field device 1c , Preferably, as in 1 shown through the glasses 7 an operating menu 14 on the display 18 the glasses 7 shown. Both the operating menu 14 as well as the other data that will be visualized will be in the augmented reality display 12 the glasses in spatial relation to the through the marker 2 of the field device 1c determinable position of the field device set. In the simplest case, the operating menu 14 or are the visualized further data through the augmented reality application 3 directly adjacent to the field device detected in the field of vision 1c on the advanced reality display 12 shown. It is also conceivable that the operating menu 14 or the other data about one in the display 18 the glasses 7 virtual line with the corresponding field device 1c are connected, so as to be represented or visualized in spatial relation to it.

Through the portable control unit or glasses 7 But not just a direct wireless data connection 11 with a selected field device 1c but also another wireless data connection 15 with a cloud 16 , which preferably outside the automation system 10 is established. This results in further operating options for the field devices of the automation system 1a, 1b, 1c. For example, a field device by a ggfl. several other operators can also be remotely operated. This can be the extended reality display 12 over the cloud 16 the other operator or the other operators 17 is made available. For example, one outside the automation system 10 located operator 17 perform a remote parameterization or configuration of the field device. But not only a remote operation is by making the other wireless data connection 15 possible, but also, the transmission of specific information from a database located outside the automation system 10. This is done in a first step on the mobile operating device 7 provided identification data to the cloud 16 to then make information specific to the field device whose identification data was transmitted to make available on the mobile operating device 7. Such specific information may be, for example, an instruction manual, a maintenance plan, a spare parts list and the like for the corresponding field device.

Via the mobile or portable control unit 7 and the resulting augmented reality application or app 3 can one by the operator 8th on the display 18 the control unit 7 shown operating menu 14 and a field action corresponding to the detected operator action is detected on the field device via the wireless data connection 11 be initiated. For example, in this way a parameterization of the field device can be made, which previously had to be carried out, for example, by an input to a locally attached to the field device control.
