DETECTION DEVICE, METHOD AND COMPUTER PROGRAMM FOR DETECTING A PHYSICAL QUANTITY AND SERVER FOR ALLOCATING A TRANSMISSION TIME SLOT

摘要

The invention relates to a detection device (100) for detecting a physical variable, wherein the detection device (100) is assigned to a group of detection devices (100), wherein each detection device (100) of the group of detection devices (100) is assigned an identifier, wherein the group detection devices (100) is designed to communicate with a server entity via a communication network, comprising a detector (101) for detecting the physical variable, wherein the detector (101) is designed to output data which represents the physical variable, and a communication interface (103) which is designed to receive a broadcast signal from the server entity via the communication network, wherein the broadcast signal indicates occupancy of transmission time slots in a predetermined transmission interval by assigning identifiers of detection devices (100) to transmission time slots, wherein the communication interface (103) is designed to select a free transmission time slot from the predetermined transmission interval if no transmission time slot is assigned the identifier of the detection device (100), and wherein the communication interface (103) is designed to transmit the data to the server entity via the communication network in the selected transmission time slot.
