摘要： A single-phase electric furnace transformer is provided according to the basic principle of the invention, comprising: a single magnetic core, said magnetic core comprising two side columns and at least one main column; a main transformer, comprising a first primary side winding and a first secondary side winding which are disposed on said at least one main column, wherein said first primary side winding consists of a first winding and a second winding which are connected in series with each other; and a voltage regulating autotransformer, which is disposed on one of two side columns of said magnetic core, and which comprises a second primary side winding and a second secondary side winding, wherein said second secondary side winding is an adjustable winding having on-load tap switch, and said adjustable winding is connected in series between the first winding and the second winding of said main transformer. The direct effect on the regulating winding and the regulating switch by the over-voltage of the grid can be avoided in the single-phase electric furnace transformer of the invention, and the voltage between two terminals of the primary winding of the main transformer can be reduced. Furthermore, the winding of the voltage regulating transformer is disposed on the side column of the main transformer in the invention, so that the material and the transformer loss can be reduced, and the installation space of the transformer can be decreased.

摘要： Disclosed is a method for determining the relationship between a track-circuit current signal and a railway vehicle location, including: sending, by a track circuit, current signal across a railway track block; measuring the current signal for different railway vehicles running successively on the railway track block; aligning the measured current signals and calculating a reference curve as the average value of all the aligned curves by using a Dynamic Time Warping algorithm, this reference curve representing the relationship between the track-circuit current signal and the railway vehicle location on the railway track block.

摘要： A method controls the height of a floor of a car of a vehicle relative to a platform. The car includes a body provided with a distance sensor, at least one bogie and at least one secondary suspension between the bogie and the body. The method includes measuring the distance between the distance sensor and the platform via the distance sensor, calculating the difference between the height of the platform and the height of the floor from the measured distance, and adjusting the height of the secondary suspension based on the difference.

摘要： A computer implemented method is for determining railway vehicle movement profile type of a railway vehicle movement profile. The railway vehicle movement profile includes a sequence of measured transmitted currents of a transceiver of a track circuit with respect to the time. The method includes obtaining a railway vehicle movement profile, normalizing the railway vehicle movement profile, extracting one or more features from the normalized railway vehicle movement profile, determining the distance of the extracted features with respect to each centroid of a railway vehicle movement profile type determined in a classification process, and assigning the railway vehicle movement profile to the railway vehicle movement profile type with the closest centroid

摘要： A multimodal terrestrial transport network (1) includes first and second networks (L1, L5), each of which is equipped with an operating system (SE1, SE2). The module (63) according to the invention is associated with an interchange station (H3) where the first and second networks are interconnected. It includes: an interface (83) for communicating with the operating systems of the first and second networks; means (84) for providing an overview of the traffic in a monitoring area (DS3) covering part of the first and second networks in order to update the overview data based on traffic data provided by the operating systems, and an engine (87) for executing operating rules based on the overview data and suited to generate instructions suited to modify the traffic within a control area (DC3).

摘要： A method is for determining a status of a track section of a railroad. Each end of the track section is connected to a respective detector. One of the two detectors transmits a current along the rails of the track section towards the other detector and receives a current transmitted along the rails of the track section from the other detector. The track section is further equipped with a computer in communication with the two detectors. The computer calculates an instant value of the status of the track section as a function of an instant vector based on a measure of an intensity of the current transmitted by a first of the detectors as measured by the first detector (Txl1), a measure of an intensity of the current received by the first detector as measured by the first detector (Rxl1) and a measure of an intensity of the current transmitted by the second detector as measured by the second detector (Txl2).

摘要： The invention relates to a railway vehicle comprising a car (14) and a bogie (16). The bogie (14) comprises a chassis (28) and a secondary suspension system (30). The secondary suspension system (30) comprises: a set (34) of springs; a jack (36) comprising two ends (44, 46); and a supply device (38) of the jack (36). The jack (36) is configured to go from a first so-called retracted configuration in which the jack (36) is only connected to the car (14) by the first end (44) to a second so-called deployed configuration in which the jack (36) is also connected to the chassis (18) by the second end (16).
The power supply device (38) is configured, in the deployed configuration, to supply the jack (36) so as to move the car (14) away from the chassis (28) or to keep the distance between the car (14) and the chassis (28) constant.
