摘要:
A train control method and apparatus for controlling the movement of trains with high safety by detecting trains on sections of track by an electronic blocking system. A wayside communication element (wayside transponder) 5 is placed in each block section on a track on which a train 1 runs. A cab communication element (cab transponder) 3 which can communicate with the wayside communication elements on the track is placed on the train 1. When receiving a train identifier (ID) from a train, a wayside control device transmits the current position information and the stop position information to the train. The cab communication element of the train 1 receives the current position information and the stop position information, creates a protection speed pattern between the current train position and the stop position from the received information, and limits the speed of the train 1 by the protection speed pattern.
摘要:
Trains and points are patrolled by a telegram containing the block occupancy information as a section that only one train is permitted to occupy, the information for giving lock position instructions to a point, and the point position information. This telegram is updated in order to get the right of block occupancy that is not held by other trains, and to give lock position instruction to the point. The train checks the block which this train is allowed to occupy, confirms that the point in this block has been set to the lock position specified by this train. Reading the aforementioned telegram, the point checks the lock position instruction given to itself and controls its lock position. A signaling system characterized by reduced designing and manufacturing costs is provided.

A message that contains train on-track information and reservation information of a train detection section and direction information and reservation information of a switch is circulated among a train detector, switch machine, signal device controller and a route indicating device. Via a signaling message, the train detector transmits the train detection result to the signal device controller and the route indicating device, the switch machine can transmit switch condition to the signal device controller, the route indicating device transmits route reservation to the switch machine and the signal device controller. Based on the transmitted train detection result, switch condition and route reservation condition, the signal device controller transmits travel permission or travel non-permission for the assigned route to a train.

摘要:
A signaling safety system includes transmitter-receiver units for ground-train communication by radio in regular safety operation mode, using a base station and an antenna. The position of each train car is communicated from the cars to a ground train controller which detects the presence of a train on-rail. Based on the latter information, information is transmitted from the controller to each of the cars regarding corresponding speed limits. In addition to such radio transmitter-receivers, the signaling safety system also includes additional communication devices, such that, when each of the cars approaches a specific range, car information from each of the cars can be received by the controller, by communication between ground communication devices and an on-train communication device which are installed so as to communicate with each other. Concurrently with the regular safety operation, by the alternative safety system, the presence on-rail of each of the cars is controlled for each new block section. When ground-train communication by radio fails, the controller switches to operation by the alternative safety system so that safe operation of the train can be continued.
摘要:
A message that contains train on-track information and reservation information of a train detection section and direction information and reservation information of a switch is circulated among a train detector, switch machine, signal device controller and a route indicating device. The train detector updates train on-track information of a train detection section contained in the signaling message, the switch machine updates switch direction information in the signaling message, and the route indicating device updates reservation information of the train detection section and the switch contained in the signaling message. Via the signaling message, the train detector can transmit the train detection result to the signal device controller and the route indicating device, the switch machine can transmit switch condition to the signal device controller, the route indicating device transmits route reservation to the switch machine and the signal device controller, and based on the transmitted train detection result, switch condition and route reservation condition, the signal device controller transmits travel permission or travel non-permission for the assigned route to a train.
摘要:
Even if any failure occurs in radio in the regular safety, confirmation of train existence on-rail and safety control can be continued by a backup system in the substitutive safety. To a signaling safety system that by ground-train communication by radio in the regular safety using a base station 102 and an antenna 107, the position of each of cars 100 is notified to a ground train controller 101 as information of existence on-rail from the cars 100 and on the basis of the information of existence on-rail, information of speed restriction is transmitted from the controller 101 to each of the cars 100, a substitutive safety system that when each of the cars 100 approaches its specific range, by communication between ground communication devices 103 and 104 and an on-train communication device which are installed so as to communicate with each other, car information from each of the cars 100 can be received by the controller is newly added. Generally, concurrently with the regular safety, by the substitutive safety system, the existence on-rail of each of the cars 100 is controlled for each new block section. However, when the ground-train communication by radio cannot be used in this state, the controller 101 switches the operation by the regular safety to the operation by the substitutive safety and the train control and safety control by the substitutive safety system can be continued.
