Monitoring a vehicle cargo space for objects connected to beacon-transmitting devices

Abstract

A cargo space is monitored for objects connected to respective beacon-transmitting devices which transmit identification signals associated with the objects. Signal strengths of received signals and repetition periods associated therewith are determined using a monitoring device which checks whether each received beacon identification signal identifies a respective object in an object inventory of the cargo space based on comparisons of the signal strengths with current signal strength threshold values respectively associated with them and on comparisons of the respectively associated beacon repetition periods with respective current repetition period threshold values. The monitoring device detects whether the cargo space is currently in a first state (in which loading and unloading operations of objects in the cargo space is permissible) or a second state (in which loading and unloading is not permissible). The monitoring device adjusts signal strength threshold values and repetition period threshold values only during the second state.
