In addition, if the control from the central traffic control data processing unit CTC cannot be performed sufficiently for some reason, the display panel control data processing unit 3 controls the trains within its control range. The timetable information is read by accessing the timetable file 4, and based on the train departure information, it is displayed on the display board 121.
Display information is sent to 12-2° . . . so that a predetermined display is made on the display panel.

In the timetable file 4, information such as the train number, boarding platform, departure time, destination, etc. according to the train schedule of the day is stored in the order of departure time.

For example, in the case of a station on the way, points N, R, and H are prepared at points in front of the arrival side of the station, point ■ is prepared at the center of the platform, and point L is prepared at a predetermined point on the departure side of the station.

Considering the case where a train arrives, first, when the train advances to point N, the train number of the arriving train is confirmed, and then when it advances to point R, an announcement is made to notify the arrival of the train. When the train reaches a point, information regarding departing trains is transmitted one after another from the data processing device CTC, or the train schedule file 4 is read out and prepared for the next display.

Then, when the train advances to point ■, an announcement of an arriving train is made, and when the departure bell is pressed, an announcement of train departure is made, and the contents of the display panel 12 are changed when the train advances to point L after departure. do.

Information that informs that a train has advanced to point N, R, H, Information on point L is required.

As described above, the train guidance process is automatically performed based on the train schedule information and the train advance information, and each display panel displays a predetermined display or changes the display accordingly.

However, even in the above system, there are cases where a failure occurs in the display panel control data processing device 3 itself, resulting in incorrect display on the display panel 12.

Under such a failure state, it is impossible to operate the data processing device 3 from the console 6, so in the present invention, the console 6 issues an all-clear instruction to the all display panel 12 from the signal converter panel 11. constructed in such a way that it can be carried out.
