System and method for monitoring a work situation

A system for monitoring a working situation, said system comprising at least one mobile sensor unit, at least one communication node, at least one sensor node which is formed by the communication node or is provided additionally, and a central evaluation unit,

• wherein the at least one mobile sensor unit comprises at least one sensor for measuring at least one first physical variable describing an activity or a state of an individual carrying the mobile sensor unit, a transmitter for the wireless transmission of measurement values of the at least one first physical variable, which are detected by the at least one sensor of this mobile sensor unit, to the at least one sensor node, and an energy store for the supply of electricity to the transmitter,
• wherein the at least one sensor node comprises at least one sensor for measuring at least one second physical variable describing a state of an environment of the sensor node,
• wherein the at least one communication node comprises a receiver for receiving the measurement values of the at least one first physical variable which are transmitted by the transmitter of the mobile sensor unit, and a communication unit for transmitting the measurement values of the at least one first physical variable, which are received by the receiver of this communication node, and measurement values of the at least one second physical variable, which are detected by the at least one sensor of the sensor node, to the central evaluation unit and
• wherein the central evaluation unit comprises a communication unit for receiving the measurement values of the at least one first physical variable and of the at least one second physical variable, said measurement values being transmitted by the communication unit of the communication node,
• wherein system is configured to assign the measurement values of the at least one second physical variable, which are detected by the at least one sensor of the sensor node, to the mobile sensor unit, which is localised in the environment of this sensor node, at least at one point in time and to transfer these together with the measurement values of the at least one first physical variable, which are detected by the at least one sensor of the mobile sensor unit, which is localised in the environment of this sensor node, at least at the point in time, to the central evaluation unit as being assigned to one another and there to store them and/or process them further.
