| 摘要 | PURPOSE:To continuously and accurately detect a running state, by simultaneously transmitting an ultrasonic wave and an electromagnetic wave during the running of a moving vehicle, and arranging a detector in a running path side to receive said ultrasonic wave and electromagnetic wave while operating and detecting the running state of the moving vehicle. CONSTITUTION:Light or an electromagnetic wave such as a radio wave is transmitted from a synchronous signal transmitter 17 in synchronous relation to the burst wave transmitted from a burst wave transmitter 19. Ultrasonic sensors 21a, 21b receive the ultrasonic wave intermittingly transmitted from an ultrasonic sensor 15. The ultrasonic waves received by the sensors 21a, 21b are inputted to frequency measuring circuits 29a, 29b to measure the altitude of frequency. This measured value is inputted to an operating and judging circuit 31 to operate the speed of a moving vehicle and judgement such that the moving vehicle approaches or goes away. An initial condition is inputted to this judgement and the speed and advance direction of the moving vehicle are displayed by a display circuit 35 and the running state of the moving vehicle can be continuously and accurately detected. | ||||||
