SEW-EURODRIVE converts the first mobile assistance system for production at e.GO Mobile to 5G technologies. This is because e.GO relies on industry 4.0 for its production and assembly in plant 1. SEW-EURODRIVE was already involved in the concept phase: SEW Bruchsal's mobile assistance systems are now being used in the Aachen production facility.
e.GO Mobile is also breaking new ground in networking and the associated data exchange between mobile assistance systems and with other production steps. In communication, the company is now starting data communication together with Vodafone, Ericsson and SEW-EURODRIVE via a mobile network that is completely isolated from the public mobile network. The companies are using the standards and protocols of the upcoming 5G technology that are already available. SEW-EURODRIVE is upgrading its first mobile assistance system to the latest mobile radio standards, with others to follow.
First 5G network for automotive production
For the first time in Germany, the 5G technologies "Mobile Edge Computing" and "Network Slicing" are used in automotive production in an autonomous network. Mobile assistance systems, machines and tools thus exchange information almost in real time - about the current location, the current battery status or the planned route. The mobile radio technology that Vodafone provides specifically and virtually for e.GO Plant 1 (Network Slicing) reduces the delay time with which the data is transmitted (latency) to less than ten milliseconds.
Mobile Edge Computing
The mobile assistance systems are equipped with sensors and independently record all environmental information. Because the recorded data is evaluated directly in the production hall in small real-time computing centers (Mobile Edge Computing), it is returned to the vehicle in real time by mobile radio. Based on the analyzed data, the vehicle adjusts its direction of travel, steers, brakes and accelerates automatically. In the near field, of course, a mobile assistance system can navigate autonomously with the built-in, referenceless navigation or another positioning method.
GB bandwidths and short latency times
A total of 36 small mobile phone antennas in the 8,500 square meter production hall will guarantee bandwidths in the gigabit range and low latency times of a few milliseconds in the future. This will make communication between the machines even faster, digital penetration of the production processes higher and workflows even more efficient. The companies involved are thus replacing WLAN communication and are already building up a wealth of experience in the use of cell radio-based communication.
