| To reduce the size, weight and cost of an interrogator which is included in an RFID system and required to have a high output power, the interrogator for transmitting a signal shares a radio wave source or a power supply with a portable wireless terminal such as a mobile phone or a portable communication device. For this purpose, a radio frequency transmitter signal is subjected to amplitude modulation by information to be transmitted to a transponder. Furthermore, part of the radio frequency transmitter signal extracted using a coupler is used to perform synchronous detection on a radio frequency receiver signal returned from the transponder, and data coming from the transponder are extracted. | ||||||

| (57)【要約】 本発明は、距離測定値に基づく位置特定方法に関する。 そのような方法では、移動局と基地局間の距離は、二局間の一方向の伝播時間を見つけることによって測定される。 この一方向伝播時間は、位置信号を送り該位置信号の到達時間を測定することによって得られる。 問題点は、受信局で検出されそのような測定に使用される信号が、直接的な経路よりも長い反射された無線経路に一致することである。 これは、不正確な位置を生む。 本発明は、距離計算が、直接的な経路であると予想される最短の無線経路を経由する伝播と対応関係にある第１の位置信号の到達時間を使用することによってされることを保証するための方法を提案する。 これは、複数のメッセージを含む位置信号を使用し、最短経路が検出されるよりエネルギーの高い信号を得るために受信側で組み合わせられることによって実現される。 | ||||||

| PROBLEM TO BE SOLVED: To provide a reception wave transmission device and a mobile unit identification system for measuring the number of specific mobile units and the distance to a specific mobile unit. SOLUTION: A base station 21 generates a diffusion signal that is subjected to spectrum diffusion, and transmits an up diffusion signal with a different line frequency by channels A and B via transmission antenna 22a and 22b. On the other hand, the up diffusion signal is subjected to specific, individual machining by a specific identification card 31, and is sent back as a down diffusion signal by an X channel, so that the base station 21 receives the down diffusion signal that has been sent back by a reception antenna 23. As a result, the base station 21 performs correlation with waveform by the down diffusion signal in reference with the waveform of the up diffusion signal that has already been transmitted, hence can count the number of identification cards 31 that have returned the down diffusion signal by the X channel according to the correlation value, and measuring distance to the identification card 31 from the base station 21. | ||||||

| PROBLEM TO BE SOLVED: To accurately detect a position of a vehicle while a consumption of a battery is inhibited. SOLUTION: A base station 58 gives a request at a constant interval by an instruction of a position detection service center 59. When a vehicle V receives the request, it transmits a response signal including an ID information. The position detection service center 59 determines a position of the vehicle V based on the response signal and provides the position information by a request from a management center 60. A power source is fed to a response signal transmission means of the vehicle V from a battery of the vehicle. A power source supply from the battery is maintained for a continuing time set longer than an interval of the request even after a main power source switch is disconnected and a response to the request from the base station 58 can be carried out. As a result, a position at the time of stopping of the vehicle can be accurately grasped at the management center 60. COPYRIGHT: (C)2002,JPO | ||||||
