Abstract: A key storage device for storing a key provided with an identification code, including a locking unit which has an unlocked state in which the key can be removed from the key storage device, and a locked state in which the key is locked in or on the key storage device. The key storage device includes a control unit connected to the locking unit and having a data interface, the control unit operable to read out the identification code of the key and to provide the identification code of the key at the data interface.

Abstract: Method for controlling a wearable user device, which is a sensor and/or information device including establishment of a wireless communication link between the user device and a gateway, transmission of a connection event message to the process control system, wherein the connection event message contains an identifier of the user device, an identifier of the gateway and information on the successful establishment of the communication link, transmission of sensor data from the user device to the process control system, generation of at least one control instruction by the process control system in response to the received sensor data, wherein the control instruction is generated depending on the identifier of the gateway and depending on the received sensor data, and transmission of the at least one control instruction to the user device. Furthermore, a wearable user device as well as a control system are disclosed.

Abstract: A method for tracking a device of a wearable user equipment for a work system, wherein the device detects whether it is connected to a power supply, and the device transmits an identification message when it is connected to a power supply. Moreover, a device as well as a work system are shown.

Abstract: A method for monitoring a work system including a plurality of sensor mechanisms and a control system. The method includes creating sensor data as well as event data packets during operation by a user by way of the sensor devices, transmitting event data packets to a correlation module of a monitoring system, receiving context information by way of the correlation module, correlating event data packets with the context information by way of the correlation module and creating context records by way of the correlation module that are based on the event data packets correlated with the context information, creating a report on the state of the work system and/or on deviations from the previous operating sequence of the work system and/or including a system improvement by an analysis module based on the context records. Moreover, a system is shown.
