The utility model discloses a fire isolation device around a railway crossing, and relates to the technical field of railway fire protection. Comprising a fixed fireproof plate, the fixed fireproof plate comprises two pairs of first arc-shaped grooves, each pair of first arc-shaped grooves are formed in different edges of the fixed fireproof plate respectively, and the two first arc-shaped grooves in the different edges are located in the different sides of the fixed fireproof plate respectively; the railway crossing fireproof plate has the advantages that the fixed fireproof plate and the movable fireproof plates on the two sides are used in cooperation, so that a proper unfolding mode can be selected according to the actual fire behavior of a railway crossing, in the case of small fire, the railway crossing fireproof plate is unfolded into a U shape to surround a fire source, and in the case of big fire, the railway crossing fireproof plate is unfolded into a line shape to stand on the periphery of a rail; meanwhile, by means of the first sealing structure and the second sealing structure, when the movable fireproof plate is unfolded, the seam between the movable fireproof plate and the fixed fireproof plate can be sealed in sequence, flames and high-temperature smoke are prevented from leaking from the seam, the fire isolation effect is further improved, and normal operation of the railway crossing is guaranteed.

This invention discloses an intelligent detection and real-time early warning method and system for foreign object intrusion at railway crossings, belonging to the field of railway traffic operation technology. The method includes joint calibration of a visible light camera, an infrared camera, and a millimeter-wave radar. Based on the calibrated joint sensing devices, visible light images, infrared images, and radar echo signals are collected. An edge computing device detects and locates foreign objects at railway crossings based on the visible light images, infrared images, and radar echo signals. The edge computing device then evaluates the hazard level of the foreign object and issues an early warning based on the detection results. This invention achieves accurate identification and segmentation of foreign objects in complex scenarios through multi-sensor collaboration and an improved YOLO v8 network, significantly improving detection efficiency and response speed. Based on a multi-dimensional hazard scoring model, it achieves quantitative threat assessment and graded early warning, triggering alarms only for high-risk targets, avoiding resource waste, and significantly improving the intelligent level of railway safety management.

This invention belongs to the field of simplified grade-separated bridge technology, specifically relating to a simple grade-separated bridge with a cement-steel frame structure for railway crossings. It includes a main component and two ramp components connected to the opposite side of the main component. The two ramp components are symmetrically arranged. Pedestrian staircases are provided on both opposite sides of the main component, with each of the two pedestrian staircases corresponding to one of the ramp components. This invention, by setting up the main component, ramp components, and pedestrian staircases, forms a three-dimensional crossing system for railways and highways. The bridge deck system and pedestrian surface system are separated, allowing for separate passage for vehicles and pedestrians. Vehicles cross the railway via the carriageway and connecting surface system, while pedestrians and non-motorized vehicles pass independently via the pedestrian staircases and pedestrian surface system. Side railings, enclosure railings, and central railings provide all-round safety protection, completely eliminating direct conflict between trains and road users spatially and significantly reducing the probability of railway accidents.

The invention concerns a method for controlling a vehicle which can determine if the vehicle is located on a railway crossing and depending on the vehicle's speed or driving direction generate actions. The method comprises the steps to determine if the vehicle is located on a railway crossing; determine if the vehicle speed is below a threshold or if the vehicle is reversing; based on the combined outcome of the determinations, generate a vehicle control signal and / or generate a user information output. The invention further concerns a vehicle control system and an advanced driver assistance system.

The present invention relates to a structural element for a level railway crossing, such as a central slab or approach made of prefabricated hydraulic concrete slabs, wherein the crossing comprises a prefabricated central concrete slab; a first prefabricated side slab; a second prefabricated side slab, each arranged parallel to the sides of the prefabricated central slab and so as to leave the railway rails clear; and at least one concrete approach, wherein the approach is so efficient that with the passage of cars and trucks the approaches do not compact in such a way as to lower several centimeters with respect to the level of the concrete slabs, and wherein it is provided with a prefabricated hydraulic concrete anti-slip structural element to prevent slippage of the approach, improve settlement and anchorage on the crossing protection ramp.

A warning light assembly and railway crossing including such an assembly are disclosed. An example warning light assembly includes a housing, an illumination device at least partially positioned within the housing, and a movement detection circuit positioned within the housing in a fixed position relative to the illumination device. The movement detection circuit can include a plurality of sensors of different types, and is configured to detect a change in position or orientation of the warning light assembly relative to an initial position, and, in response to detecting the change in position or orientation, generate an alert.
