Abstract: A system for exclusive track resource sharing is provided. Some embodiments provide an exclusive track resource sharing system including onboard control units and a resource manager. Onboard control unit is provided in each of trains and is configured to communicate with another onboard control unit in another train. The resource manager is configured to record ownership status information of track resources of the plurality of trains, to provide the ownership status information of the track resources to the onboard control unit, and to generate and deliver a resource entitlement or resource authority to the onboard control unit. The resource authority is configured to be owned by a single onboard control unit. The onboard control unit possessing the resource authority is configured to seize or release the track resources corresponding to the resource authority and to control the track resources corresponding to the resource authority.

Abstract: An apparatus and method for protecting a communication device of a railroad car is provided. The apparatus includes an antenna portion configured to include main antennas and an auxiliary antenna, a main receiver configured to check a magnitude of a received signal transferred through the main antennas of the antenna portion, an auxiliary receiver configured to check a magnitude of a received signal transferred through the auxiliary antenna of the antenna portion, and a controller configured to compare the magnitude of the signal received by the main receiver and the magnitude of the signal received by the auxiliary receiver, determine whether there is a jamming signal according to a comparison result, and take a preset countermeasure when it is determined that there is a jamming signal.
