Abstract

PURPOSE:To collect information on a traveling body with high precision by making a feedback loop oscillation circuit, composed of ground-station facility including induction lines coupled with coils of mobile-station facility, to oscillate an oscillation frequency determined by the high-Q resonance circuits of an information signal transmitter circuit. CONSTITUTION:Ground fixed station facility is provided with series circuits of high- Q resonance circuits 13-1-13-n to a fixed frequency, and phase shifters 14-1-14-n as many as the number of kinds of information, and mobile-station facility information-detects 17-1-17-n fixed frequency components from outputs of antenna coils 6 and 7 through BPFs 15-1-15-n. Here, a feedback loop oscillation circuit is provided which consists of the ground fixed station facility including amplifier 8 and coils 6 and 7 of the mobile-station facility and induction lines 1, 2 and 1' coupling with those coils 6 and 7, and it is made to oscillate at an oscillation frequency determined by the resonance frequency of high-Q resonance circuits of the information signal sending circuit, thereby transmitting information from the ground fixed station to the mobile station. Consequently, it is made possible to collect mobile-body information including position detection of the mobile body with high precision.
