AUGMENTED REALITY MAINTENANCE

Augmented reality offers the opportunity to make maintenance and servicing processes in industry much more efficient. Our smart glasses guide explains how augmented reality can be used in industry and presents tried-and-tested models.

Augmented Reality

WHAT IS AUGMENTED REALITY?

Augmented reality, or AR for short, is a process in which virtual elements are added to reality or an actual "material scene". Augmented reality is not the same as virtual reality, as there is no immersion in a completely virtual world. With AR, the actual sense stimulation remains present - a crucial aspect in the context of maintenance and service.

Augmented reality in the industry

BOTH HANDS FREE FOR WORK TO BE DONE

Augmented reality can be implemented with a wide variety of hardware, anddata glasses, also known as smart glasses, are particularly recommended for maintenance processes in industrial companies.
Data glasses display context-relevant information in the user's field of vision. It is therefore no longer necessary to look at a smartphone or tablet and hands remain free.

In general, a distinction can be made between two technologies: AR light and 100% AR. Our data glasses guide will help you find the right data glasses for your individual service and maintenance requirements.

SMART GLASSES AS THE IDEAL ENTRY INTO AUGMENTED REALITY MAINTENANCE

Android-based data glasses such as the RealWear Navigator 520 or VUZIX M400 models are located between standard platforms and AR. This can be referred to as AR light, as there is no direct reality overlay. The data glasses have a 2D assistance screen located in the peripheral field of vision. Information can be sent to the external expertvia this screen - for example with the help of the bitnamic CONNECT Service HUB. At the same time , videos, application windows, documents, etc. can be received from the expert via screen sharing. The integrated microphone also enables verbal communication.

Data glasses promote efficient troubleshooting: as the camera is in the immediate vicinity of the eye, the expert can more quickly understand which component the service technician is focusing on and give appropriate instructions. Triggered functions such as annotations or laser pointers, which characterize our visual support software, are transferred directly to the screen of the data glasses.

Microsoft HoloLens

THE FULL AUGMENTED REALITY EXPERIENCE

The Microsoft HoloLens enables advanced augmented reality maintenance. The head-mounted display (HMD) offers extensive possibilities and functions, such as spatial detection using sensors, spatially appropriate visualization or the exact superimposition of real objects.

Integrate any number of 3D objects and benefit from significantly more placement options thanks to the display of virtual elements in the entire real space - in contrast to the limitations of classic 2D displays. Thanks to positioning in the entire field of view, including spatial anchoring, the virtual objects always remain in their original physical location, even if you as the wearer change your position.

With the Microsoft HoloLens, you can merge reality with virtual content and facilitate all workflows in maintenance processes thanks to the resulting spatially appropriate overlays.

Areas of application

ULTRASONIC MEASUREMENT WITH AR IN AVIATION

Challenge
A component from aircraft construction is to be inspected for material defects. An ultrasonic measuring device is used for so-called non-destructive material testing: This method makes it possible to carry out material testing without causing damage to the component

The technician usually has to look at the screen of the device to which the measuring device is connected (e.g. a laptop). This is no longer necessary with the use of the Microsoft HoloLens, making work more efficient.

How augmented reality supports

With the help of bitnamic CONNECT, a Hololens application guides the user step by step through the entire testing process. Overlaid texts and images show the user which action is required in the current step or how this action is to be carried out. In the course of the scenario, possible fault areas are indicated by animated markings, which the user should then check with the ultrasonic measuring device. After a measurement process, the result is displayed directly above the inspected area on the component. This makes the inspection significantly faster and minimizes errors. The device can be operated completely hands-free. This scenario has already been subjected to a large number of user tests and has shown consistently positive results.

IOT-INTEGRATION

The scenario described below shows a possible integration of machine data in combination with the advantages of our remote maintenance solution.

An industrial robot is visualized three-dimensionally in space (provided by Salt and Pepper). The industrial robot is part of a production plant and is equipped with various sensors. The sensor values are transmitted to our servers by the Beat Monitoring System (BMS) and visualized live on display elements on the model.

The data is synchronized with our servers. If an error occurs on the industrial robot, the HoloLens user is informed. The affected component of the robot is highlighted in color and the corresponding error text appears.

As troubleshooting is only possible with the support of an expert, the user can then set up a remote maintenance session and transmit their own camera image to the external expert. Thanks to the full integration, the expert can see the video image as well as the sensor data and the error message of the faulty component. With the help of the expert, the fault can be rectified and the industrial robot returned to a fault-free state. The networking of machine data and the infrastructure of our solution enables fast and efficient assistance with troubleshooting tasks. The virtual representation of a machine was chosen for this application example; in real use, the sensor data would be visualized directly on the actual machine instead (see ultrasound scenario above).

We would be happy to advise you on the possible applications of augmented reality
