Technical Field

[0001] This utility model relates to the field of digital railway intelligent communication equipment, specifically a railway intelligent edge node device. Background Technology

[0002] For long-distance railways, railway equipment and facilities must operate 24 hours a day to ensure train safety, which puts pressure on daily maintenance. While current equipment room operation and maintenance management adopts an unmanned on-site model, and key equipment rooms are managed through power and environmental systems, equipment rooms in mountainous areas, tunnels, and especially repeater stations along the route face challenges due to insufficient construction costs, limited maintenance personnel, and the unique operating environment of railways. During daily maintenance, the various unknowns arising from the on-site environment prevent maintenance personnel from accurately and intuitively locating faults, analyzing root causes, and providing timely and accurate risk warnings. This necessitates frequent on-site inspections, resulting in a significant waste of manpower and resources, increasing maintenance costs and operational risks. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0018] The structure of this utility model is as follows: Figure 1 As shown, this utility model provides a railway intelligent edge node device, including central equipment and external equipment. The external equipment includes an audible and visual alarm device, a protective door access control unit, a camera, and several tunnel-specific lighting devices. The central equipment includes a main control board, a first communication circuit breaker, a second communication circuit breaker, a chassis access control unit, an Ethernet switch, and a power module. The main control board is directly connected to the chassis access control unit and the protective door access control unit via a switch. The main control board is connected to the audible and visual alarm device, the first communication circuit breaker, and the second communication circuit breaker via RS485 interfaces. The main control board is connected to the Ethernet switch via a network cable. The first communication circuit breaker is connected to the camera via the Ethernet switch, and the second communication circuit breaker is connected to several tunnel-specific lighting devices. The power module's input end is connected to an external power supply via a power filter, and its output end is connected to the main control board, the first communication circuit breaker, and the second communication circuit breaker. The Ethernet switch is a PoE Ethernet switch, with at least one optical interface and eight electrical interfaces.

[0019] The power module input / output control of this utility model is as follows: the power filter inputs 220V / AC to the power module. The power module outputs 12V / DC to the main control board. The power module outputs 48V / DC to the first communication circuit breaker and the Ethernet switch.
