摘要： A measuring stretch along a railway track of a transloading system has an array of switches with respective sensors positioned for engagement by a wheel of a railway carriage. The lateral displacement of the railway carriage wheel is prevented by a guide disposed along the rail at the level of the head at a distance of 30 to 50 mm from the head of the rail. The row of switches can be provided on the opposite side of this rail. The switches synchronize a transloader with the rail vehicle via a computer to which the switches are operatively connected.

摘要： The invention relates to a device for continuously measuring the position of a rail vehicle moving along a rail track, using a measurement section lying parallel to the rail track. On the measurement section, the position of each rail vehicle is measured and fed into a computer which controls the drive means of loading/unloading devices. In this arrangement, switching elements (1) are distributed along the length of the measurement section and are each provided with a mechanical sensor and arranged in the vicinity of a rail (4) of the rail track in such a way that the sensors are touched by the wheels (3) of the rail vehicle passing through the measurement section; and a conducting rail (12) extending along the entire length of the measurement section is provided next to one of the rails (4) on the wheel flange side of the wheel (3) passing over it and at a distance (A) from the head of the rail (4) of between 30 ad 50 mm.

摘要： The measuring device according to the invention uses a capacitive sensor biased by a DC voltage and conditioned by a charge amplifier with DC bias, this charge amplifier having a high-pass filter structure, preferably of second order. The technology of the sensor and of the connecting cable is coaxial. The measuring system is calibrated theoretically without having to resort to sampling.
