摘要： PROBLEM TO BE SOLVED: To measure fluctuation of a long rail, which is performed by manual operation and its working efficiency is conventionally low, similar to a rail joint opening measuring in a train traveling at high speed.
SOLUTION: A rail side laser oscillator is driven by a drive signal transmitted from an on-vehicle transmitter and outputs a leveling string substitute laser beam, and an on-vehicle light receiving sensor receives the leveling string substitute laser beam and outputs a leveling string substitute signal. An on-vehicle identifier sensor detects a punch mark substitute and a rail joint opening/long identifier on the rail and outputs a punch mark substitute signal and a rail joint opening/long determination signal. A rail joint opening measurement and a long measurement are changed over based on the rail joint opening/long identifier signal, an on-vehicle laser doppler sensor outputs a doppler signal, an on-vehicle rail joint opening identifier sensor outputs the rail joint opening identifier signal. When it is changed over into the long measurement based on the rail joint opening/long determination signal, the fluctuation of the long rail is measure based on the leveling string substitute signal, the punch mark substitute signal, and the doppler signal, and when it is changed over into the rail joint opening measurement, the rail joint opening is measured.

摘要： PROBLEM TO BE SOLVED: To obtain a deviation measuring apparatus of a low cost and a small size capable of mounting in a business vehicle by measuring a deviation state of a trolley wire by using a discriminating method based on a level or the like of an output signal of a sensor. SOLUTION: Detection signal data of sensors A to D stored in a memory means are read by a processing means such as a personal computer or the like, and a graph indicating, for example, the relationship between a moving distance or time of a vehicle and a level and an amplitude of output signals of the sensors A to D is output from a print or display means or the like. An operator decides a trolley wire based on the graph or the like by using a predetermined discriminating method. Thus, a place in which a deviated distance of the wire is a first distance x or above can be discriminated. Since number and installing positions of the poles installed between stations are known in advance, substantial positions of the places in which the wire is deviated at the first distance x or above can be discriminated.

摘要： PROBLEM TO BE SOLVED: To solve the problem that fluctuation quantity measurement of a rail requires much labor and time, and has poor working efficiency and problematic measurement accuracy. SOLUTION: In this method, a laser beam is outputted from a laser oscillator installed on a reference body fixed on the side of the rail, and the laser beam is used as a substitute for a leveling string, and an identifier installed on the rail is photographed on a screen by a camera loaded on a vehicle by using the laser beam an a trigger, to thereby measure the rail fluctuation quantity from the fluctuation of the image position of the identifier on the screen. A clear image can be photographed even under sunlight by combining emission from a stroboscope with an electronic shutter of the camera.

摘要： PROBLEM TO BE SOLVED: To surely detect the existence of a rail joint even when a length of a joint opening between rail members is short. SOLUTION: Laser beams X, Y (reflected beams ZX, ZY) for detecting a fish plate are provided to be reflected on the fish plate 23 when the fish plate 23 exists in a position where the laser beams X, Y emitted from two laser beam sources 10X, 10Y cross each other. Amounts of the reflected beams ZX, ZY transmitted through a photoreceiving lens 11 to be condensed in a photoreception detector 12 are great thereby compared with the case where the fish plate 23 does not exists. The fish plate 23 is detected thereby to detect the existence of the rail joint.

摘要： PROBLEM TO BE SOLVED: To provide a discriminating method for ATS capable of precisely discriminating the kind of ATS without depending on a manual work or ATS resister and a measuring method of ATS capable of precisely inspection measuring the set position and function of ATS. SOLUTION: The height of an ATS 2 from a rail surface is measured by a displacement sensor 4 loaded on a vehicle. Further, a moving pulse showing the traveling distance is provided by a laser Doppler sensor 5 loaded on the vehicle. These data are combined to discriminate the kind of the ATS 2 without depending on an ATS resister. The set position of the ATS 2 can be also precisely determined. Further, the F-value and Q-value are determined by a measuring coil 6, and it is judged whether the ATS 2 specified from these data satisfies the F-value and Q-value to be possessed or not.
