Abstract

The invention relates to a device for measuring the height of piles of a substance in railway environments and to the associated measuring method. The device comprises: a load cell (2); a presence detector (3) comprising at least two presence sensors (3’) located on the same vertical plane at different heights and configured to activate when they detect the presence of the substance; and processing means (5) configured to calculate a first height of the pile of the substance on the basis of the weight measured by the load cell (2) and a second height on the basis of a reading from the presence detectors (3). The processing means are configured to select the first height as the height of piles of the substance if there is coherence between the first and the second height, and to select the second height as the height of the piles of the substance if there is incoherence between the first and the second height.

Abstract

The invention uses the power of electrical sub-stations (2) that power a network of catenaries (1) and the braking energy that the trains transmit to the network of catenaries (1), for the mass power supply of equipment for charging vehicle batteries (8) from the catenary (1), from an energy storage device (5), or from both, according to the power required by the equipment (8), the power stored in the device (5), and the power of the catenary (1), as long as the catenary power required by the trains is supplied.

Abstract

The invention automates the management of traditional telephone messages used to request operations relating to the interruption/connection of an area of an electric line in order for line maintenance, repairs or alterations to be made. The invention comprises a remote power control centre that communicates with portable devices (2) which are each assigned to at least one maintenance operator and which are used for the transmission of a telephone message based on the information stored in the remote control centre (1) in which the different events that occurred during the request are managed and stored. The operations requested in the telephone message are transmitted from the centre (1) to the installation (14) of the electric line in order to be implemented. The centre can be used to manage blocks relating to the interruption/connection elements of the installations (14) of the electric line and the centre also allows maintenance operators to check the state of said interruption/connection elements via the above-mentioned portable devices (2).

Abstract

The method is based on applying a vertical force (F) in the centre (P) of a first section (A-B) of the rail (1) of a railway, and measuring the displacement thereof in order to represent the graph corresponding to the force applied-displacement and calculating the gradient of the straight line defined by said graph, thereby obtaining the longitudinal tension of the rail (1), in equivalent centigrade degrees. The method also comprises calculating the temperature of the free effort of the rail (1) by adding the value of the rail temperature to the calculated longitudinal tension. The method avoids having to cut the rail (1), and so simplifies measurements and reduces costs. The invention also concerns an apparatus for acting according to the described method.
