[Problems to be solved by the invention]
However, it is difficult to monitor the internal information and the like of the non-power supply transponder responder because the connection line does not come out after molding. As a method of monitoring internal information, a method of transmitting to the interrogator when there is a request from the interrogator can be considered, but as an operation on the interrogator side and the responder side, in addition to normal information transmission / reception operation, monitoring operation This hinders miniaturization and cost reduction of the transponder system. In addition to the response information transmission operation for the question from the interrogator on the responder side, it is also necessary to transmit monitor information, and sufficient monitor information cannot be transmitted due to limited communication time and limited transmission information .

[0011]
In FIG. 1, a non-power supply transponder responder 20 according to this embodiment includes a normal operation unit 21 that performs a normal transponder response operation for transmitting response information to the interrogator in response to the question information from the interrogator, and the normal operation. And a monitor unit 22 that monitors the operation state of the unit 21 and outputs the monitor information to the outside.

It comprises a question information storage section 7 as means, a response information storage section 8 as response information storage means, a transmission section 9, a transmission antenna 10, and a control section 11 as control means. Here, the power wave receiving coil 2 and the voltage generating unit 3 constitute a power supply means, and the receiving antenna 4, the receiving unit 5, the question information decoding unit 6, the question information storage unit 7, the response information storage unit 8, and the transmission unit 9. The transmission antenna 10 and the control unit 11 constitute information transmission / reception means. The reception antenna 4 and the reception unit 5 constitute reception means, the question information decoding part 6 and the question information storage part 7 constitute question information storage means, and the transmission part 9 and the transmission antenna 10 constitute transmission means. . The operation of each part of the normal operation unit 21 is the same as the conventional one, and the description of the operation of each part is omitted here.
[0012]
The monitor unit 22 is information in the middle of operation in the reception unit 5, the question information decoding unit 6, the question information storage unit 7, the response information storage unit 8, the transmission unit 9 and the control unit 11 of the normal operation unit 21, or operation results. The shared memory 23 as the monitor information storage means for storing the information, the power wave receiving coil 24 for receiving the monitor unit power wave from the monitor information caller 30 shown in FIG. The monitor unit voltage generator 25 that generates the monitor unit power supply voltage based on the generated power wave, and the monitor information in the shared memory 23 that is driven by the power supply voltage from the monitor unit voltage generator 25 is processed. The monitor control unit 26 for outputting, the monitor information transmitting unit 27 for modulating and outputting the output from the monitor control unit 26, and the modulated signal from the monitor information transmitting unit 27 as the monitor information caller 3 Constituted a transmitting antenna 28 for transmission to. Here, the power output coil 24, the monitor voltage generator 25, the monitor controller 26, the monitor information transmitter 27, and the transmission antenna 28 constitute a monitor output means. The power wave receiving coil 24 and the monitor voltage generator 25 constitute a monitor power supply unit, and the monitor controller 26, the monitor information transmitter 27 and the transmission antenna 28 constitute a monitor information transmission controller.
[0013]
Further, the power wave receiving coil 24 and the transmitting antenna 28 of the monitor unit 22 are arranged so as not to interfere with the power wave receiving coil 2 and the transmitting antenna 10 of the normal operation unit 21 that performs transmission and reception with the interrogator. For example, since the monitor information caller 30 can be closer to the responder 20 than the interrogator, the power wave receiving coil 24 and the transmitting antenna 28 of the monitor unit 22 can be made smaller, or the power wave receiving coil of the monitor unit 22 can be reduced. 24 and the transmitting antenna 28 are arranged at right angles, or a shielding plate for shielding the signal from the interrogator is provided between the normal operation unit 21 and the monitor unit 22. It is possible to avoid.
[0014]
As shown in FIG. 2, the monitor information caller 30 includes a power wave generator 31, a power wave transmission coil 32 that transmits a power wave generated by the power wave generator 31 to the responder 20, and a responder 20. Receiving monitor 33 for receiving monitor information, monitor information receiving unit 34 for amplifying and demodulating monitor information received by receiving antenna 33, and monitor information storage for storing monitor information received by monitor information receiving unit 34 And a monitor information display unit 36 for displaying the monitor information stored in the monitor information storage unit 35.
[0015]
Next, the operation of the non-power supply transponder responder 20 of this embodiment will be described. First, the operation of the normal operation unit 21 will be briefly described. When the power wave receiving coil 2 receives a power wave from the interrogator, a power supply voltage is generated from the power generation unit 3 and supplied to each unit of the normal operation unit 21 as a power source. As a result, each unit becomes operable. When the question information from the interrogator is received by the receiving antenna 4, the information is inputted to the question information decoding unit 6 via the receiving unit 5, and the information is decoded and stored in the question information storage unit 7. The control unit 11 outputs the corresponding response information in the response information storage unit 8 to the transmission unit 9 based on the stored question information, and transmits the response information to the interrogator side via the transmission antenna 10. Thus, a normal information communication operation is performed between the interrogator and the responder 20.
[0016]
Then, during this normal communication operation, information in the middle of operation or information of operation results in each unit in the normal operation unit 21 is stored in the shared memory 23 in the monitor unit 22. The monitor information stored in the shared memory 23 can be received on the monitor information caller 30 side by transmitting a power wave from the monitor information caller 30 of FIG. 2 to the power wave receiving coil 24 as a monitor information transmission command. That is, when the power wave receiving coil 24 receives a power wave from the monitor information caller 30, a power supply voltage is generated from the monitor voltage generator 25, and each part of the monitor unit 22 operates. As a result, the monitor control unit 26 reads the monitor information in the shared memory 23, outputs the monitor information to the monitor information transmission unit 27, and is transmitted from the transmission antenna 28 to the monitor information caller 30 side.
[0017]
When the monitor information is received by the reception antenna 33, the monitor information caller 30 stores the monitor information in the monitor information storage unit 35 via the monitor information reception unit 34, and displays the monitor information on the monitor information display unit 36.
According to such a configuration, since the monitor unit 22 capable of transmitting the monitor information of the operation state of the transponder responder 20 to the outside is included in the responder 20 separately from the normal operation unit 21, the normal operation of the responder 20 is performed. The operating state in the molded transponder responder 20 can be monitored in a non-contact manner without affecting it. Therefore, it is possible to improve the reliability of the transponder responder 20 in which no connection line appears outside after molding, and to improve the safety in rail traffic, for example.
[0018]
【The invention's effect】
As described above, according to the first to third aspects of the present invention, since the monitor unit that can transmit the monitor information of the operating state of the transponder responder to the outside is built in separately from the normal operation unit, The operating state inside the molded transponder responder can be monitored in a non-contact manner without affecting the normal operation of the vessel. As a result, the reliability of the transponder responder that does not have an external connection line after molding can be improved. For example, the safety of railway traffic can be improved.
