RADIO TAG SENSOR SYSTEM AND METHOD FOR CALIBRATING SAME

WIPO Patent Application WO/2011/135886

A1

This invention comprises: a plurality of radio tag sensor chips each of which incorporates a sensor and a unique identification number and is operative to wirelessly perform communications and is wirelessly fed; a plurality of micro base stations that are operative to wirelessly communicate with and wirelessly feed the plurality of radio tag sensor chips; and a central processing apparatus that is operative to communicate with the plurality of micro base stations via a connection network. Each of the micro base stations is operative to wirelessly communicate with and wirelessly feed only radio tag sensor chips existing in an area in charge of that micro base station. In each area in charge, at least one radio tag sensor chip, which is not included in another area in charge, is existent. The central processing apparatus is operative to: control the communications using the connection network; collect, via the plurality of micro base stations, sensed values, which are acquired by the sensors of the plurality of radio tag sensor chips, to make a spatial distribution map of the sensed values; and update the spatial distribution map of the sensed values as time elapses.
