<p>This invention pertains to a train control system using wireless communications. In this train control system a portable wireless device (PVRS) is detachably mounted to a maintenance vehicle (3) and the maintenance vehicle (3) is incorporated into a wireless train control system. The carriage length of the maintenance vehicle (3), the portable wireless device (PVRS) number, the frequency used for wireless communications, and the time that the maintenance vehicle (3) is on the track (main line) (2), etc., are recorded in the portable wireless device (PVRS) as basic information for the maintenance vehicle (3). The basic information for the maintenance vehicle (3) is sent to a ground device (SC) via trackside wireless devices (WRS) and a base wireless device (SRS), the distance measurement results from communications between the portable wireless device (PVRS) and the trackside wireless devices (WRS) are sent to the ground device (SC), and the ground device (SC) performs actions such as setting the maintenance car on-track warning range. As a result, safety during maintenance work using the maintenance vehicle can be improved whilst reducing cost.</p> |
