Abstract:
1. A radio tag sensor system comprising: a plurality of radio tag sensor chips which incorporate respective sensors, store unique identification numbers, perform wireless communications and which are wirelessly supplied with electric power; a plurality of micro base stations which perform wireless communications with the radio tag sensor chips and wirelessly supply electric power to the radio tag sensor chips; and a central processing unit which performs communications with the micro base stations via a connection network; wherein each of the micro base stations performs wireless communications with and wirelessly supplies electric power to only those of the radio tag sensor chips which are disposed in an assigned region thereof; wherein each of the assigned regions includes at least one of the radio tag sensor chips which is not included in the other assigned regions; wherein the central processing unit controls the communications via the connection network; wherein the central processing unit sends a sensed value collection command via the connection network to the micro base stations to which indicated addresses are allocated; wherein only the micro base stations to which the indicated addresses are allocated wirelessly send identification numbers; wherein only the radio tag sensor chips that store one of the unique identification numbers matching any of the wirelessly sent identification numbers wirelessly send sensed values from the sensors thereof; and wherein the central processing unit collects the sensed values from the sensors of the radio tag sensor chips through the micro base stations, generates a spatial distribution map of the sensed values, and updates the spatial distribution map with time.
