Title: POSITION-SENSING SENSOR AND POSITION-SENSING SYSTEM
Abstract:
The invention relates to a position-sensing sensor of a position-sensing system comprising a first and a second radio transponder, each of which has a transmitting and receiving unit connected to an antenna and has a memory unit for persistent data storage. The first radio transponder has an energy supply source and can be selectively put into an idle state with reduced energy consumption and into an active operating state with complete range of functionality. In the active operating state, at least one radio connection to at least one first radio transponder reading unit is established for position sensing. The second radio transponder, which can be inductively supplied with energy by a radio transponder reading unit, is designed, upon entering a sensing range of a second radio transponder reading unit, to transfer the first radio transponder from the idle state into the active operating state or to transfer position information associated with the second radio transponder to a server of the position-sensing system via the second radio transponder reading unit.
