Electric resonance element, detection apparatus and moving vehicle control system |
摘要 |
An electric resonance element includes an electric resonator comprising a coil wound around magnetic materials and a capacitor. The electric resonance element is housed in a vessel made of non-magnetic materials? A detection apparatus for detecting the electric resonance element comprises a transmitter for transmitting an electromagnetic wave and a receiver for detecting the echo wave transmitted from the electric resonance element. A moving vehicle is controlled using a system which comprises the electric resonance element buried in a road, and the detection apparatus installed on a vehicle for detecting echo waves transmitted from electric resonance elements. The detection apparatus comprises a transmitter for transmitting an electromagnetic wave specific to the electric resonance element, a receiver that detects the echo wave, and a element or a circuit to suspend the operation of the receiver while the transmitter is on duty. <IMAGE> |
