#TOSMAC

The problemOverhead 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 ideaDevices which measure cables vibration and predicting its remaininglife based on these measurements. This manner this project will try tosolve this problems using:

• Solar panel• Cloud computing

Socket.IO – APP.jsNode.js modules

var socket = require('socket.io');

var server = app.listen(3000);var io = socket(server);

io.on('connection', function(socket){console.log('A user is connected');

app.post('/refresh', function(req, res){var buses = String2Array(req.body.data);saveCloudant(buses);io.emit('refresh', {data: buses});res.send('Data Received');});

#TOSMAC

Socket.IO – js/controller.jsNode.js modules

var socket = io();var ids = [];

socket.emit('connection', {});socket.on('refresh', function(buses){buses.forEach(function(bus){

update(bus[0], bus[1], bus[2]);});});

function update(id, passengers, lotation){$('#' + id + " span").html(passengers + " of " + lotation + " passengers");changeColor(id, passengers, lotation);}

#TOSMAC

Cradle – APP.jsNode.js modules

#TOSMAC

var cradle = require('cradle');var env = JSON.parse(process.env.VCAP_SERVICES);var credentials = env["cloudantNoSQLDB"][0].credentials;var cloudant = new(cradle.Connection)(credentials.url, credentials.port, {cache: true,secure: true,raw: false,auth: {

var saveCloudant = function(buses){buses.forEach(function(bus){

passengers.save(bus[0], {date: new Date().getTime(),passengers: bus[1],lotation: bus[2]

}, function(err, res){err ? console.log('err: ', err) : console.log('res: ', res);
