Meanwhile ...
What
happened?

#TOSMAC
But how can we
help preventing
this?

#TOSMAC
Let’s explore it
better...

#TOSMAC
IoT using Node-RED

#TOSMAC
What about TI Sensor Tag CC2541?

#TOSMAC
What about BeagleBone Black?

Things

#TOSMAC
Use Case - Fire Alarm App Steps
1. Connect the USB Hub (with Wireless adapter + Bluetooth adapter) to
the BeagleBone Black.
1. Connect the BeagleBone Black to the computer.
1. Make sure to have a WiFi connection (my cellphone is hotspotting).
1. Set up the BeagleBone Black.

#TOSMAC
The problem
Overhead transmission lines are often vibrating due to the action of winds.
As a consequence:
• Cables experience alternate stresses due to wind-induced vibration
• Alternate stresses may lead them to fatigue failure

Cable vibrating Cable/clamp assembly Cable failure due to fatigue

#TOSMAC
Vibration recorders and the project idea
Devices which measure cables vibration and predicting its remaining
life based on these measurements. This manner this project will try to
solve this problems using:
• Solar panel
• Cloud computing
Prototype design Vibration recorder
