RADIO COMMUNICATION DEVICE AND COMMUNICATION METHOD

摘要

PROBLEM TO BE SOLVED: To provide a radio communication device capable of making a communicable distance long while reducing circuit power consumption and capable of reducing cost by making a chip size small.SOLUTION: A radio communication device (IC tag) comprises: a detection circuit (13) which detects a reception signal to restore an information signal component; an identification code generation circuit (15) which generates or stores an identification code of the radio communication device itself; a measurement circuit (16) including a detection element for detecting a physical quantity of a measurement object; a state switching circuit (18) of which the output state is switched by a signal from the detection circuit each time the detection circuit detects a pulse as the information signal component included in the reception signal; and a transmission circuit (20) capable of transmitting internal predetermined data to the outside. Each time the output state of the state switching circuit is switched, the identification code or measurement data acquired by the measurement circuit are successively transmitted by the transmission circuit.SELECTED DRAWING: Figure 1
