Remote monitoring systems are used in many different applications, for example in energy supply, automation and transportation. The devices are usually monitored and managed via a network. Sensors and monitoring technologies collect and transmit data on the operation of devices, systems and production processes to higher-level control systems. With the help of this collected and evaluated data, users can optimize processes and the quality of production, identify and rectify problems and plan maintenance work at an early stage – see also predictive and preventive maintenance and condition-based monitoring.
