Description

[Detailed Description of the Invention] [Field of Application of the Invention] The present invention relates to a device for controlling the operation of a moving object such as a train, and in particular, it has a history of signal signals for setting the course, and in response to approaching driving, it can set an appropriate course. This invention relates to a mobile vehicle operation control system that allows reset.

[Background of the invention]

This type of mobile vehicle operation control system is capable of providing route information for each region according to a predetermined operation schedule for routes for trains and other mobile objects that are divided into certain regions. and detects when a moving object enters the area, sets the route information on a traffic light, etc., controls the operation of the moving object based on the set route information, and detects when the moving object enters the relevant area. It is common to detect that the vehicle has left the area and reset the route information set in a traffic light or the like.

Incidentally, in order to increase transportation efficiency, urban railways such as subways are operated with the distance between moving objects such as trains as short as possible. This means that moving objects such as trains come extremely close together on the same course. In such a situation,
When the preceding train arrives at the signal reset point, i.e. detects that it has left the predetermined area and resets the signal, the permissible running speed of the following train is determined to match the indication of the signal. Due to this restriction, the brakes are applied, which impedes improvement in transportation efficiency through predetermined approach driving. To prevent this, conventionally, when a preceding train resets its course, it searches for a following train, and if that train is beyond the control request point and is taking the same course as its own train, it is redirected. A method was adopted in which the system was not reset. However, this method has the disadvantage that it requires searching for a following train and investigating the control system of that train, resulting in complicated processing.

[Purpose of the invention]

SUMMARY OF THE INVENTION An object of the present invention is to provide a train operation control device that eliminates the above-mentioned drawbacks and can easily perform approaching operations through simple processing.

[Summary of the invention]

In order to achieve the above object, the present invention sets route information when a train enters a predetermined area, and always stores the train number in a storage means, so that the train leaves the area. The course information is reset only when the contents of the storage means at the time of the transfer are the own number.

[Embodiments of the invention]

Preferred embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram showing the equipment configuration for realizing an embodiment of the train operation control device according to the present invention, taking the train operation control device as an example.
Further, FIGS. 2 to 4 are plan views shown for explaining the operation.

In the figure, 1, 1a, and 1b are trains as moving objects, 2 is the track (course) of the train, 3 is the station platform, 4a, 4b, and 4c are traffic lights, 5 is a route setting request point on the track, and 6 is a This is the point where course reset is requested. Thus, points 5 and 6 are predetermined regions, and the trajectory 2 is divided into predetermined regions.
Further, reference numeral 7 is a local information detection device, 8 is a train information storage device that stores train position and control information, etc., and 9 is a train information storage device that stores train position and control information.
is the basic diagram storage device, 10 is the course calculation device, 1
1 is a route control device, 12 is a storage device for storing signal control status, 13 is a control output device, 14 is a train operation status display device, and a train information storage device 8.
A basic timetable storage device 9, a route calculation device 10, and a train operation status display device 14 constitute a timetable verification device X. The control output device 13 drives the traffic light 4 and provides route information to the area.

In the above-described configuration, the movements of the trains 1a and 1b are captured by the local information detection device 7,
The train information storage device 8 is stored in association with the timetable information in the basic timetable storage device 9. train 1a
When the train enters a predetermined area, that is, when it enters the course set request point 5, it sends out a course set request signal, and the information is taken in by the local information detection device 7 and stored in the train information storage device 8. The signal 4 to be controlled by the route calculation device 10 is determined based on the train position and timetable information. Next, in response to this, the route control device 11 stores the number of the own train in the corresponding position of the signal control state storage device 12, and the control output device 13 controls the signal 4a to set course information.

Next, when the train 1a leaves the predetermined area, that is, when it enters the course reset request point 6, it sends out a reset request signal, and as described above, the detection device 7,
The route reset function of the route control device 11 resets the route information of the traffic light 4a via the control output device 13 via the storage device 8, route calculation device 10, etc.

By the way, conventionally, when the train 1a resets the route information of the signal 4, the following train 1b has entered the route set request point 5, and the train 1b
The train information storage device 7 is used to check whether the route taken by the train 1a has the same timetable as the own train 1a, and the corresponding signal 4a is not reset when the train takes the same route. As already mentioned, this makes the process complicated. Therefore, in the present invention, a storage device 12 is provided as a storage means for storing the traffic light control state, and this is used for control.

First, in Fig. 2, when the vehicle enters a predetermined area (that is, course set request point 5 is detected).
Since the train 1a is the leading train, its own train number 1a is stored in the signal control state storage device 12a corresponding to the signal 4 corresponding to the timetable information.
Next, in FIG. 3, when it is detected that the following train 1b has entered a predetermined area, that is, it has entered the course set request point 5, the signal 4a of the own train 1b is activated to alert the preceding train 1a. If so, the preceding train number 1a is erased and the own train number 1b is stored in the signal control state storage device 12a. After that, as shown in Figure 4, the preceding train 1a
When it is detected that the train 1a is leaving a predetermined area, that is, entering the course reset request point 6, the memory in the signal control state storage device 12a is
Therefore, the traffic light 3a is not reset. Of course, as shown in FIG. 2, when the following train 1b has not entered the predetermined area, that is, when the train 1a leaves the predetermined area before entering the route set request point 5, that is, when the train 1a leaves the predetermined area, Course reset request point 6
If the signal control state storage device 12a stores the own train 1a, the route information set in the signal 4a will be reset.

In short, in this embodiment, when the preceding train 1a enters a predetermined area, its own number is registered in the storage device 12a, and even if the preceding train 1a is within the predetermined area, the following train 1a
When train b enters a predetermined area, the memory contents of the storage means 12a are updated and registered to the number of train 1b, and the preceding train 1
When a exits from a predetermined area, the storage device 12a
By referring to the contents of , if a number other than the train number (train 1a) is registered, the course will not be reset.

According to this embodiment, the route setting mechanism of the route control device 11 includes a signal control state storage device 1 configured to control the route ahead of the own train 1a or 1b.
By adding a simple mechanism to record the number of the own train 1 at the location corresponding to the signal 4 controlled by the own train 1 in No. 2, the route reset mechanism of the route control device 11 can determine whether or not to reset the signal. In order to decide, it is only necessary to look at the signal state storage device 12 and determine whether or not the own train is stored.
This has the advantage that the mechanism is simpler than the conventional mechanism for checking the conditions of the following train.

〔Effect of the invention〕

As described above, according to the present invention, there is an effect that approaching driving of a moving object can be performed with simple processing.
