System Architecture
The demo system is composed of 4 Lamppost Node and 1 Auto-car node.
1.1: Each lamppost node contains:
- 1 x Host Machine (5512)
- 1 x Raspberry PI (equipped with 2 x ZigBee CC2520 communication module)
- 2 x Camera (accessible via RTSP video stream)
The detailed configuration is shown in the following figure:
1.2: The auto-car node contains:
- 1 x Raspberry PI (equipped with 2 x ZigBee CC2520 communication module)
- 1 x Laptop / Computer (use for route planning and movement control, etc.)
The entire system consists of 3 sub-programs:
-
Lamppost Host Program (runs on the root node and slave node)
- Source files are placed under <proj_root>/src/LPHost directory
-
Lamppost Hook Program (runs on RaspberryPI of the root node)
- Source files are placed under <proj_root>/src/LPHook directory
-
Control Program (runs on the auto-car node)
- Ssource files are placed under <proj_root>/src/Ctrl directory
The interactive behaviour of each module is illustrated in the diagram below.
