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 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 solve such problem that it takes the labor and time to measure the variation quantity of a rail and the operation efficiency is bad. SOLUTION: A reflecting body discrimination sensor mounted on a vehicle traveling on a rail irradiates a rail reflecting body provided to the rail and a reference reflecting body fixed nearby the rail with light and photodetects reflected lights from both the reflecting bodies to separately discriminates the rail reflecting body and reference reflecting body, and generates pulses at a constant distance interval proportional to a movement distance during the travel of the vehicle and measures the distance between both the reflecting bodies from the number of the mentioned pulses between both the reflecting bodies to measure the rail variation quantity.

摘要： PURPOSE:To improve the peripheral speed acquiring accuracy of the objective method by acquiring the peripheral speeds of two gears meshed with each other at their meshing contact points from the peripheral speed of each gear at a plurality of positions having different phases. CONSTITUTION:The peripheral speeds Va and Vb of a rotating surface 66 which rotates together with a gear 100 to be measured in one body at two locations where the phase respectively differs by 180 deg. and 90 deg. in the rotating direction from the meshing contact point Pc of the surface 66 with the other gear 102 meshed with the gear 100 are acquired. Assuming that the center O1 of the gear 100 is displaced only in the tangential direction of the contact Pc, the peripheral speed V1 of the gear 100 at the contact point Pc becomes (R1/R+1)Vb-Va (where, r1 and R respectively represent the pitch circle radius of the gear 100 and radius of the surface 66). Therefore, the peripheral speed V1 can be found from the peripheral speeds Va and Vb and the error of the gear 100 can be detected from the difference between the peripheral speed V1 and the peripheral speed V2 of the gear 102 at the contact Pc.

摘要： PURPOSE:To enable a chamfered inclined surface to be measured as a rail length even if it is located at starting and ending edge parts of the rail. CONSTITUTION:A laser beam (a) for Doppler is emitted from a laser Doppler sensor 3 to an upper surface and a chamfering part of a rail 1 and then a Doppler signal is output from its scattering light (b). On the other hand, a laser beam (d) for identifying gap is emitted from a sensor 4 for identifying gap to the upper surface 2 and the chamfering part from directly above and then a reflection light (e) which is reflected skewly is received by either of two light receivers 4 at a chamfering part 1c or the laser beam (d) for identifying gap is emitted to the upper surface 2 and the chamfering part skewly for receiving a reflection light (e) which is reflected directly above at the chamfering part using a light receiver.
