As a result, since the information on the predetermined position is symbolized, the amount of information transmitted from the installation transceiver 2 can be reduced, and the information on the predetermined position can be provided in a plurality of languages.

  In such an installation transceiver 2, the receiving unit 21, the demodulating unit 22, the storage unit 23, the control unit 24, the modulating unit 25, the transmitting unit 26, and the power source unit 27 are integrated into an IC chip and bonded to one circuit board. And is sealed with resin. Thereby, since the installation transceiver 2 can be reduced in weight and size without using a commercial power source or a battery, it can be easily installed everywhere.

  On the other hand, the portable transceiver 3 demodulates the information guide signal S2 from the receiver 31 that receives the response carrier C2 transmitted from the installation transceiver 2 and the response carrier C2 that is received by the receiver 31. Based on the demodulator 32, the information data at a predetermined position based on the information guide signal S2 demodulated by the demodulator 32 and the confirmation signal S1 for confirming the information on the predetermined position, and output from the controller 34 A voice conversion unit 35 that converts the information data at a predetermined position into a voice, a modulation unit 36 that frequency-modulates the confirmation signal S1 output from the control unit 34, and a question that frequency-modulates the confirmation signal S1 by the modulation unit 36 A transmission unit 37 that transmits the carrier wave C1 to the installation transceiver 2 and a power supply unit 38 that supplies power to each unit that requires operation power are provided.

  The reception unit 31 includes a reception antenna that absorbs electromagnetic wave energy and converts it into electric circuit energy, and the transmission unit 37 includes a transmission antenna that converts electric circuit energy into electromagnetic wave energy and radiates it into space. Similarly to the installation transceiver 2, it is possible to transmit and receive with one antenna.

  The control unit 34 receives the response carrier wave C2 transmitted from the installation transceiver 2 by the reception unit 31, demodulates the information guide signal S2 by the demodulation unit 32, and then stores a plurality of information registered in the storage unit 33 in advance. An information control circuit 34a is provided that selects and outputs information data that matches the guidance code included in the information guidance signal S2 from information data at different predetermined positions. The control unit 34 receives the response carrier wave C2 transmitted from the installation transceiver 2 by the receiving unit 31, demodulates the information guide signal S2 by the demodulation unit 32, and then includes a plurality of languages included in the information guide signal S2.

The language code registered in the storage unit 33 can be switched by a language switching unit 39 that can switch the language by a dip switch or the like or by voice. Further, the control unit 34 receives the response carrier wave C2 transmitted from the installation transceiver 2 by the receiving unit 31, demodulates the information guide signal S2 by the demodulation unit 32, and then includes the position included in the information guide signal S2. When the code is continuously recognized, a reading control circuit 34c having a function of refusing to read the information guidance signal S2 is provided.

  The voice conversion unit 35 includes an information voice conversion circuit 35a that outputs a voice signal based on the information data output from the information control circuit 34a to a speaker.

  The portable transceiver 3 has a transmission function for intermittently transmitting the interrogation carrier C1. As a result, the interrogation carrier wave C1 is intermittently transmitted from the portable transceiver 3, so that the person carrying the portable transceiver 3 is close to the entrance, stairs, intersections, paintings in the museum, etc. You can reach your destination without checking with taxiways or guide blocks.

  Since the power supply unit 38 of the portable transceiver 3 must be carried, a primary battery or a secondary battery is used. Further, such a portable transceiver is not limited to the one having only the communication function as described above. For example, a portable terminal using radio waves as a communication means such as a cellular phone, a transceiver, a portable radio, a portable TV, etc. A communication function may be added, and in this case, notification means such as a mobile phone and a portable television can add not only audio but also a video function, or notify only by video. In the portable transceiver 3 described above, not only audio but also a video function may be added, or only video may be notified.

  The installation transmitter / receiver 2 of the guide device 1 configured as described above generates a DC power by converting the power of the carrier wave into a DC current, and thus the power is smaller than that of a commercial power supply or a battery. Because you are communicating by, you can fly far to a certain extent. Further, by setting the frequency used in the data communication of the installation transceiver 2 and the portable transceiver 3 to 30 to 999 MHz, the FM wave can be skipped to some extent, and preferably by setting the frequency to 100 to 999 MHz. Waves can be moved farther (around 6m). In particular, when the frequency is set to 322 MHz, it is possible to extend the communication distance without obtaining a license from a radio station in Japan (Japan). If this frequency is set to 422 MHz, the communication distance can be extended without obtaining a license from an overseas radio station. In this data communication, various data transmission methods such as an error control method and a spread spectrum communication method can be used depending on the communication contents.

  Next, operation | movement of this guidance apparatus 1 is demonstrated using the flowchart shown in FIG. The installation transceiver 2 is installed on the staircase St (FIG. 3), the bus stop BS (FIG. 4), the traffic light S (FIG. 5), the toilet door T (FIG. 6), the post box P (FIG. 7), etc. The storage unit 23 of the installation transceiver 2 includes, for example, Japanese (code 200), English (code 201), German (code 202), French (code 203), and Chinese (code 204). ) And the like, a guidance code “There is a staircase (code A00)”, and character information “It is a pedestrian bridge” are stored. Further, in the storage unit 33 of the portable transceiver 3, for example, the information data “Code is available” corresponding to the guide code, the information data “Code is available”, the information data “Code A01”, the information data “Code A02” It is assumed that the information data “There is a postbox” of the code A03, the information data “There is a toilet” of the code A04, and the language code is selected as the code 200 by the language switching unit 39.

  In such a situation, when the person carrying the portable transceiver 3 comes to a position where the installation transceiver 2 installed on the stair St can receive, the interrogation carrier C1 is intermittently transmitted from the portable transceiver 3. (Step 101), the receiving unit 21 of the installation transceiver 2 receives the interrogation carrier C1 (Step 201). The power of the interrogating carrier wave C1 received by the receiving unit 21 is converted into a direct current by a power source unit 27 having a power generation circuit, and is supplied as power to each unit that requires an operating power source. The communication time is determined by the time constant of the power supply unit 27. The demodulating unit 22 supplied with power demodulates the confirmation signal S1 from the interrogating carrier wave C1 and outputs it to the control unit 24. The control unit 24, together with the position code stored in the storage unit 23 based on the confirmation signal S1 demodulated by the demodulation unit 22, language codes 200, 201, 202, 203, 204,..., A guide code A00, The text information “It is a pedestrian bridge” is read out and output to the modulation unit 25 as an information guide signal S2 (step 202). Since the modulation unit 25 outputs the response carrier wave C2 obtained by frequency-modulating the information guide signal S2 to the transmission unit 26, the transmission unit 26 transmits the response carrier wave C2 to the portable transceiver 3 (step 203).

  The response carrier C2 transmitted from the installation transceiver 2 is received by the receiver 31 of the portable transceiver 3 (step 102), and the information guide signal S2 is demodulated and controlled by the demodulator 32 from the response carrier C2. To the unit 34. The control unit 34 checks the position code included in the information guidance signal S2 (step 103). If the same position code is continuously recognized, the reading control circuit 34c rejects the information guidance signal S2 (step 103). 104). After confirming the position code by the reading control circuit 34c, the language control circuit 34b uses the language codes 200, 201, 202, 203, 204,... The code 200 is selected and output (step 105), and the information code A00 included in the information guide signal S2 from the information data A00, A01, A02, A03, A04 registered in advance in the storage unit 33 by the information control circuit 34a. Is selected and outputted (step 106). When the information guide signal S2 does not include a guide code, the guide code is not selected and only character information is output.

  In this way, when the language code 200 and the information data “There is a staircase” are selected, the control unit 34 converts the text information “is a pedestrian bridge” together with the language code 200 and the information data “there is a staircase” into speech. It outputs to the part 35a (step 107). The voice conversion unit 35 converts the voice signal “There is a staircase” and “It is a pedestrian bridge” into Japanese corresponding to the selected language code 200 by the information voice conversion circuit 35a and outputs the voice signal to the speaker ( Steps 108 and 109). As a result, it is possible to provide audio information such as “There is a staircase” and “It is a pedestrian bridge” from the portable transceiver 3 carried by a person.

  In addition, the guide device 1 comes to a position where the person carrying the portable transceiver 3 can receive the installation transceiver 2 installed at the bus stop BS, the traffic light S, the toilet door T or the post box P. From the portable transceiver 3, audio information corresponding to each installation location can be output. Therefore, since one portable transmitter / receiver 3 can output audio information corresponding to each installation location, it is for blind people, for elderly people, for those with poor physical and mental wear, for station guidance, for aquarium guidance, for movie theater guidance. It can be used as an emergency guide for each place.

  In the above-described embodiment of the present invention, the power supply unit of the installation transceiver that constitutes the guide device may be provided with connection means that can be connected to a commercial power supply. As such a connection means, a terminal, a connector, etc. are suitable. Thereby, since it can connect with a commercial power supply according to the data amount which carries out radio | wireless communication, it comes to be able to respond also to radio | wireless communication with much data capacity which increases power consumption.
