Method and device for detecting the derailment of a guided vehicle

Abstract

The present invention relates to a method and a device for detecting derailment adapted to a vehicle guided by a guiding system including at least one guiding member interacting with a railhead (13) of a rail (1) which is useful for guiding the guided vehicle, characterised in that said device includes: a clamp (4) including a bottom jaw (41) tightly surrounding the railhead (13) of the rail (1) in a contactless manner in the closed position thereof, capable of opening by opening the jaw (41) thereof when interaction is lost between the guiding member and the rail (1), said opening resulting from said railhead (13) at least partially exiting the jaw (41), at least one top rod (421, 422) of the clamp (4) enabling mechanical transmission of the opening of the jaw (41) to at least one switch (51, 52); said switch (51, 52) including two configurations: a nominal configuration corresponding to the closed position of the clamp (4) during correct re-railing and an alarm configuration generated by mechanical transmission of the opening of the jaw (41) to the switch (51, 52), said alarm configuration being suitable for actuating at least one safety system of the guided vehicle.

Description

technical field [0001] The invention relates to a method and a device for real-time detection of derailment of a vehicle guided by a guidance system comprising guides interacting with a track for guiding the vehicle, as stated in the preambles of claims 1 and 8 . Background technique [0002] By "guided vehicle" it is meant means of public transport, such as buses, trolleybuses, trams, subways, trains or train units, etc., but also means of transport of loads, such as cranes, for which safety aspects are It is very important and their guidance is ensured in particular by a single track. The rails are used to guide the guides, which are generally supported on the rails and follow their trajectory during the movement of the vehicle. The guide, for example, enables the driving guidance system to have a steering axle of the vehicle along the trajectory defined by the rail, said axle being provided with load wheels, for example. [0003] A first known variant of guides consist...

Problems solved by technology

and again, such systems are relatively complex and require signal processing and analysis to avoid false alarms and interference from other signals

[0012] As a result, detection systems to date have been complex and expensive to implement, often including a large number of components, each of which can potentially generate false alarms of failure or derailment

In fact, the complexity of these systems is formed by a large number of components, which are prone to a large number of failures, for example associated with hydraulic or pneumatic leaks, wrong processing or interference of signals, external environmental manifestations that may distort, for example, the signals received by sensors
