Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a distributed traffic management system in which a central processing unit and a terminal processing unit are connected via a data transmission path, and the functions of the central processing unit are performed by two processing processes. The present invention relates to a control device for a distributed transportation management system, which is characterized by appropriate division of labor and mutual backup.

[Conventional technology]

As described in Japanese Patent Application Laid-Open No. 66-259566, the conventional device has two central processing units: one that mainly manages train schedules and schedules, and the other that mainly performs operation display and manual route setting. There was a processing device, and the operation display had a device that outputs from both processing procedures so that they could back up each other. The operation display output was automatically switched by mutual fault detection between the two processing units.

[Problem that the invention seeks to solve]

In the above conventional technology, as shown in FIG.
The operation display processing device was automatically switched based on failure detection, but there was a problem that automatic switching could not be performed reliably because it was difficult to detect 100% of all cases.

In addition, output devices 7 and 8 for displaying operation information were provided in both processing devices 1 and 2, and a switching device 32 was required. In addition, in order to increase the accuracy of automatic switching, it was necessary to provide mutual failure detection 33, 34 for detecting two failures.

For these reasons, the system configuration is complicated, which increases costs.

c. Means for Solving Problems] In order to solve the above problems, the following technical means were adopted.

(1) The operation display on the operation display board 3 is output only from the processing device 2.

(2) Processing device i! The operation display when 2 is abnormal is displayed on the display 6 from the processing 1 device.

[Effect]

The operation display on the operation display board is output from the processing device 1! ! 7
The output is directly output to the operation display panel 3 via the , without a switching device. In the processing bag [2], the operation is displayed on the display 6 for man-machine communication.

The operation display on the display 6 is displayed by the dispatcher pressing a button on the operation console 5 when necessary.

Since there is no automatic switching of the operation display panel, there is no need for a mutual fault detection function to improve the accuracy of fault detection.

By doing so, when the processing device 1 breaks down, the operation display will not be displayed until the dispatcher presses the button on the operation console, but there is no problem for the following reason.

(1) Operation control continues based on timetable information.

(2) Since the operation is controlled by timetable information, there is no need to manually set the route, and there is no need for detailed operation displays.

〔Example〕

An embodiment of the present invention will be described below with reference to FIG.

Output device from processing device 1 for operation display and manual route setting! Up to 7 are central devices. The transmission device 3o is connected to the transmission line 31, and 9 is a station control device installed at each station where a relay interlocking device is installed.

The central processing unit is mainly responsible for managing train schedules.

A processing bag for organizing operations and man-machine communication with dispatchers! ! ! 2, train position information and signal control status information mainly transmitted from the station control device at each station are displayed on the operation display panel 3; There are two processing devices, processing device 1.

During normal train operation, a timetable is transmitted from the central station to each station, and each station control device uses this timetable and train tracking information to control routes and run trains.

In the event of an abnormality such as a disruption to the timetable, the dispatcher uses the console 5 to make various schedule changes or input operation commands depending on the disruption to the timetable, and re-sends the rearranged schedule to the station to reflect this change. Routes are controlled by a one-time schedule. If the processing device 2 is out of order for some reason and the train cannot operate according to the timetable, the route is controlled by operating the central manual setting car.

According to the present invention, when the processing devices 1 and 2 press the button with the mutual interference value 5, the operation display is displayed on the display 6.

Furthermore, there is no need for a mutual failure detection function, and there is no possibility that a normal processing device will be stopped due to this failure detection error.

〔Effect of the invention〕

According to the present invention, it is not necessary to provide an operation display output device in both the processing devices 1 and 2, and a switching device is also not required, allowing an economical system configuration.

Furthermore, there is no fear that the operation display cannot be switched because failures in the processing devices 1 and 2 cannot be detected.
