As testing our product with a full set of sensors was unviable, we have developed a framework to simulate realistic sound levels onboard a large vessel, as well as the movement of users around said vessel.
There are two parts to the simulation framework, which are both written in Python and interact with the database:
- Simulating the sound in the rooms of the vessel (sim.py)
- Simulating the movement of officers around the vessel (movement.py)
We recommend that the framework is kept running throughout development, to ensure fresh data is constantly being outputted to the system.
sim.py is a script written using sqlalchemy that continuously simulates any number of sensors onboard a vessel. It can handle multiple rooms, multiple sensors, and multiple sensors per room.
To start sim.py, we must:
- Install the requirements required by Python.
- Create the SQLite database and place it in the root directory.
python sim.py
The script should start generating simulated data every 5 seconds and commit it in the backend.db ready for serving to the frontend.
movement.py is an application written in PyGame used to simulate the movement of officers aboard the vessel. It reads the database for users and rooms, and allows a developer to move them around.
To start movement.py:
- Install the requirements required by Python.
- Create the SQLite database and place it in the root directory.
python movement.py
The movement data will be written every 5 seconds and update the MovementEvent table in the database.
