A system for detecting and pre-warning railway roadbed deformation includes: a control box and an optical fiber-pressure sensor group. The optical fiber-pressure sensor group is formed by disposing a plurality of optical fiber-pressure sensors into a cuboid shape, and is buried in the railway roadbed for detecting magnitude of roadbed deformation in each direction. The direction of the deformation can be acknowledged easily, allowing the staff to eliminate potential risks purposefully. A time series prediction algorithm is performed to forecast a trend of the roadbed deformation in each direction, such that the staff may purposefully overhaul and correct the tracks where the roadbed is deformed excessively. At the same time, the staff may overhaul the track before the magnitude of the roadbed deformation reaches a predetermined value. Potential safety hazards may be eliminated in advance, ensuring the safety for the operation of the railroad.

Installation for power generation by means of vehicular traffic that can be located at floor level (2) of a vehicles traffic lane, wherein it has generator of electrical energy (5) modules, each of which includes: a set of mobile crossbar components (20) mounted over both sets (21a) of hydraulic cylinders (21), an hydraulic circuit (3), a linear hydraulic actuator (32), movement transformer mechanism (4) from straight swinging movement into a one-way rotating movement, and a generator (5) of electrical energy; each crossbar component (20) is moved by the own weight of the vehicles (7) crossing it, propelling a set of hydraulic cylinders (21) that, through the hydraulic circuit (3), are connected to the linear hydraulic actuator (32); this last one, through the movement transformer mechanism (4), propels the rotating movement of the electrical generator (5). When the wheel (70) of a vehicle (7) steps a mobile crossbar component (20), this last one moves downwards, so it propels the mobile arms (22) of the hydraulic cylinders (21). Once the descending cycle ends, the automatic repositioning of the crossbar component (20) takes places as a result of the floor elastic means (23).
