摘要： PURPOSE:To shorten confirmation time of information and enhance man-machine response by providing a computer with a variation detecting processing process of a system state, a process state, and a diagram alteration existence state, and displaying monitored information concerning them on a man-machine apparatus. CONSTITUTION:To a computer 1 in a traffic system, information such as content of the equipment 5 of a process, namely, position of a train, signal presentation, and a railway switch commutating state, etc., is always input through a transmission path 5, grasping a train operation state. And, content of the computer 1 is monitored by a man-machine apparatus 2 to enable men know the state of this system. In this case, a processing process that automatically monitors train information and displays it on the man-machine apparatus 2 when the train operation state became abnormal (occurrence of delay, for example) is added to the computer 1. The processing process like this is made capable of processing for abnormality in various train operations and abnormality in the process state by respectively storing them in advance and processing.

摘要： PURPOSE:To automatically change-over train diagrams by providing such an arrangement that a center processing device reads data from a train memory information device in accordance with a diagram change-over input from a control panel, and pre-change-over link are connected to post-change-over link data. CONSTITUTION:Pre-change-over link data 8 designate a turn-back of a train at a terminal station and a code of the train. The connection between the pre- change-over link data 8 and a post-change-over link data 9 is attained in such a way that a center processing device 1 receives a diagram change-over input from a control panel 3, and identifies train codes A0, B0, A1', B1' which are common to both link data 8, 9 with a diagram change-over data 10 from a train schedule memory device 2 so as to locate a connecting point, and the data is connected to the associates point. When the connection of the train codes A0-A1', B0-B1' is carried out, the train is managed in accordance with the post-change-over link data and diagram data 11 obtained corresponding to the data 9.

摘要： PURPOSE:To conduct the test before connection or the like by providing an expanded loop interface to a new loop connection section of an existing loop, flowing a data flowing to the new loop to the expanded loop and eliminating the data circulated from the new loop. CONSTITUTION:Let the existing loop in use be the loop A and the new loop be the loop B. After an interface 203 receives information B1 from the loop B, a switch 204 is thrown to the position '2', and the information B1 is sent to the loop B. Then the interface 202 receives the information A1, the switch 204 is thrown to the position 'l' and the information A1 is sent to the loop B. Then the interface 203 receives the information B2 from the loop B, the information is identified and the information sent from the loop A to the loop B is discriminated to be information An circulated from the loop B, then the information is lost at this point of time.
