DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an interlocking device or a train central control device provided with a man-machine device comprising a work station or a personal computer in a railway, and a manipulator for setting a course using a pointing device such as a mouse. It relates to a display method of a machine section.

2. Description of the Related Art A train is operated on a railway by setting a course and displaying a signal indicating progress on a traffic light, that is, a green signal. When the course is set, the interlock switches the switch at the branch of the track in a predetermined direction and locks the related equipment so as not to operate. When this operation is completed, the traffic light is displayed in blue. In order to determine the progress of the train by watching the traffic light, the train driver makes a course setting from the interlocking device, and if the conditions for displaying the green light of the traffic light are established, the traffic light turns green so that the train can be operated.

[0003] The route is set by an interlocking device installed at a station or a train central control device so-called CTC device installed at a control center. Is operated to set the course.

For example, according to Japanese Patent Application Laid-Open No. 5-16810, a route setting means sets a route by designating a pair of a starting point and a landing point by a push button on a control panel.

There is also known a method in which a course is set by designating a starting point and a landing point on a display screen using a pointing device such as a mouse.

A means for displaying menu items on a display screen is disclosed in JP-A-5-210474.

[0007]

On railway lines near a metropolitan city, there is an overcrowding of train schedules due to an increase in transportation capacity due to population concentration. It is an indispensable task to operate trains safely and smoothly even under this dense schedule.

[0008] As described above, train operation is performed by setting a course by an interlocking device installed at the station. Therefore, in order to allow the train to arrive, depart, and pass for smooth operation, it is necessary to set a smooth and appropriate course. For this purpose, the station operator must determine which train should be moved to which point and recognize which route has to be set before setting the route.

However, the number of routes differs depending on the scale of the station. In a station such as a terminal station where the number of platforms and the number of branches are large, the number of routes increases in accordance with the number. Some stations have more than 100 routes. According to the above-described method of setting a route by selecting a pair of the starting point and the destination, a large number of starting and landing points exist in a station having a large number of routes or a station having a complicated track layout. Therefore, it is difficult to determine which destination can be selected with respect to the starting point when setting a route, as the number of routes increases and as the shape of the station becomes more complicated, If you are not a person who is familiar with the arrangement of, it cannot be instantaneously determined. This means that at the stations in urban areas where the number of routes is large and the number of trains is large, the operators who set the routes require considerable attention to realize the train operation on Diamond Street, If route setting is not performed, there is a possibility that a train delay will occur. Further, in an emergency such as an accident where quick response is desired, it is not possible to quickly set a route, which may affect the operation of a subsequent train.

As described above, an object of the present invention is to make it easy for a handler to recognize a landing point which is paired with a starting point when setting a course in order to smoothly operate a train, thereby greatly improving operability. It is an object of the present invention to provide a screen display method for a man-machine device.

[0011]

SUMMARY OF THE INVENTION According to the present invention, an interlocking device installed in a station or a train central control device installed in a control center is operated by using a man-machine device including a workstation and a personal computer. Then, the starting point and the landing point displayed on the display screen of the display device of the man-machine device are designated as a pair of two points by a pointing device such as a mouse, and the route of the train is set and displayed. In the screen display method of a machine device, when a starting point on the display screen is designated by the pointing device when the course setting is performed, landing points that can be specified in pairs are displayed on the display screen by color change display or blinking display. Is displayed.

According to this, when the operator designates a starting point on the display screen in order to set a course, the destinations of the courses that can be specified are displayed on the display screen. You can instantly recognize whether it can be specified.
