Use of 2D Codes and Mobile Technology for Monitoring of Machines in Manufacturing Systems

Monitoring of machines, machine tools and robots in local manufacturing systems, especially the monitoring of communication between machines, robots work centers and other networked devices in computer integrated manufacturing is an important part of security assurance in a global manufacturing environment. The presented monitoring methods use 2D bar code technology including QR codes and Datamatrix, mobile devices currently available on the market, including smart phones (capable to utilize WiFi, 3G and UMTS technology) such as iPhone, Android, Windows Mobile and Symbian systems as well as regular UNIX-based computer systems and selected diagnostic software tools available via the Internet on GNU license. The compilation of 2D bar codes, mobile devices with WiFi, 3G and HSPDA and UMTS technology, local networks and UNIX systems, software and commands allows the introduction of a useful, flexible and scalable monitoring system, capable of being implemented in any size and any type of manufacturing systems.
