Page History
This page is a guide for real life physical experiments at in the CPM Lab at the chair i11 of the RWTH Aachen.
Start an experiment
Use the Main PC to run your HLC in the lab. When you enter the room the main PC is the one where the cable from the celing (IPS and labcam) are connected (it is the third PC from the entrance door when you go straight).

Find errors at RTI DDS transmission
Use the RTI Tool (you find it on the main PC in applications):
- Select "admin console"
- Go to domain and View Preferences
- Change the DDS Domain (on the bottom of the admin console) if necessary (the main PCs ID is 21, if you are not on the main PC you find it in /etc/profile)
- Subscribe to the topic you want to listen to (keep the "advanced settings" unchanged)→ now you can choose the selected field if it is not already displayed from the dropdown menu.
Using NUCs for distributed calculation
The idea of the NUCs is to simulate a potent computer on a real vehicle for each vehicle. If you do not use the "NUC"-mode, all calculation will be done centralized on the main PC.
Turn on NUCs
Switch on the wallplug of the server rack by using the white remote control usually close to the main PC. The NUCs start automatically and each NUC will signal the LCC individually that it is online. You can find the online NUCs in the window on the bottom next to the button "reset view" at "HLC online". When you open the menu each NUC that is online is displayed. For each vehicle there is one corresponding NUC. The IDs have to match (e.g. vehicle 6 to NUC 6).

The NUC is supposed to simulate a potent server on a real life vehicle. This server would be usually connected via LAN. In the lab the vehicle and the NUC are seperate and therefore connected via WLAN. They use the DDS strucutre to exchange data. |
Use the NUCs
- You can use the NUCs if you choose the "deploy remote" option. The script will be sent to the NUCs for calculation instead of being calculated on the main PC centrally.
- Start your program choosing "Deploy" . The script will be loaded to the NUC and started.
- Switch to the timer-tab in the LCC. When all NUC are ready ("WAITING") select "Start".
- To finish your simulation hit either "Stop" in the timer-tab or "Kill" in the setup-tab.
