System and method for monitoring, operating and maintaining an industrial plant, in particular in the metal-producing industry or the steel industry

A system for monitoring, operating and maintaining an industrial plant, in particular in a metal-producing industry or steel industry, comprising:

• at least one mobile terminal device with at least one sensor for recording measured values along a non-preprogrammed pathway within the industrial plant,
• at least one position sensor for detecting a position of the at least one mobile terminal device along the non-preprogrammed pathway in the industrial plant,
• a central data processing device for processing the measured values recorded by the at least one mobile terminal device with the at least one sensor, taking into account the position of the at least one mobile terminal device recorded with the at least one position sensor in the industrial plant, and
• at least one communication network for exchanging data between the at least one mobile terminal device, the at least one position sensor and/or the central data processing device.
