Each of the carnival societies has its own group login in the app. The float driver, as the data provider, uses this to log in and then selects their vehicle. The float driver then needs do nothing else to capture data, and the GPS tracker runs in the background, energy efficiently, without the screen needing to be active, for example. The driver can see their current location on an interactive map in the app, and thus get visual feedback that the tracker is working correctly.
As network coverage can fluctuate when there is a major event, before the parade the drivers are shown how to reconnect to the Internet after the parade. This ensures that the GPS data that is tracked offline and stored in the app is also transmitted and feeds through to the mobile backend. All the data from the app feeds through to the backend in the cloud – to the “Connected Things Management” IoT platform which is based on Axonize and Microsoft Azure. This results in the platform providing a live overview of the floats with their last transmitted locations. Post-event, the T-Systems Multimedia Solutions’ existing customer flow analysis solution can be used to generate and analyse the paths taken and the heatmap.
Altstädter Köln 1922 e.V. is one of Cologne's venerable carnival clubs and one of those responsible for the annual Rose Monday Parade around the inner city. The club came into being after the First World War and developed out of a bowling club founded in 1905. From this, the “Faithful Old Towners” got together in 1922, their stated aim being “to safeguard the tradition and provision of the genuine, popular Cologne Carnival, particularly upholding Cologne customs, typical Cologne wit and humour and Cologne's dialect and quirks within the traditional, historic Cologne carnival celebrations”. Just two years after the club was established, in 1924, the decision to form a corps was taken. In 1968 the Altstädter club was awarded the honorary title of “Traditional Cologne Carnival Corps”.
