PROBLEM TO BE SOLVED: To reduce the number of pieces of data to be transmitted by applying necessary arithmetic processing to output data from plural sensor circuits based upon a command transmitted from an interrogator to a responder. SOLUTION: This radio data collecting system consists of an interrogator 50 and a responder 51 for receiving an interrogation wave from the interrogator 50, collecting data by the interrogation wave command, modulating 8 the non- modulated interrogation wave received from the interrogator 50 based on the data, and reflecting the modulated wave as a response wave. The system is provided with an arithmetic circuit 7 for applying arithmetic processing to plural data inputted to the responder 51 by the command from the interrogator 50 at need. A response wave is generated based upon an output from the circuit 7. |
