<p>PROBLEM TO BE SOLVED: To remotely judge the condition of a sensor part by providing a control part which receives the signals of electromagnetic waves, which are received by its antenna part, and transfers both data from its memory part and the information of a read port to the antenna part. SOLUTION: The wireless response device 2 is made up of a sensor part 21, a contact part 22, an antenna 23, a power supply part 24, a modem part 25, a control part 26, a memory part 27, and of a read part 28. An interrogator 3 is rested on a trolley 4. And the interrogator 3 is provided with an antenna receiving/transmitting signals. Electromagnetic waves S transmitted by the antenna of the interrogator 3 are received by the antenna part 23 of the wireless response device 2. And furthermore, electromagnetic waves 6 transmitted by the antenna part 23 of the wireless response device 2 are received by the antenna of the interrogator 3. The wireless response device can receive the electromagnetic waves 5 transmitted by an interrogator located in a remote site, and also can provide information to the interrogator 3 by transmitting the electromagnetic waves 6 from the antenna part 23.</p> |
