BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic interlocking device,
More specifically, a technology that complements the difficulty of prioritizing the processing among field devices, which is a drawback of the matrix data processing method, with data string data, and performs high-speed inter-station interlocking processing with a large number of routes and complicated interlocking conditions According to.

[0002]

2. Description of the Related Art An electronic interlocking apparatus is provided with train route information and the like, and performs an interlocking process corresponding to a train route based on an interlocking chart. As a method of performing such interlocking processing, a spur method and a matrix data method are known.

The Spur system is described in detail in "Interlocking Device" (Electrical Introduction for Railway Engineers, Signal Series 5, Japan Railway Electrical Engineering Association). To explain the outline, we have various units corresponding to the interlocking equipment elements (field equipment) such as departure and arrival points of the course, points, etc. Each unit is connected to its own unit and how it is connected In addition to being given as connection data, connection data indicating the nature of the own unit is given, and when route control data is given, spur connection processing is performed while referring to data described in each unit. Then, the interlock condition necessary for the course control is extracted, and the interlock process is performed.

In the matrix data system, linked equipment elements drawn for each route are described as matrix data, and when route control data is given, linked processing is performed based on the matrix data. The processing order of the linked equipment elements corresponding to the course is complemented by train tracking or the like.

[0005]

However, the conventional spur-type electronic interlocking device has an advantage in that the route of the train and the processing order of the interlocking equipment elements required according to the traveling can be easily correlated. However, as the scale of interlocking increases, interlocking processing time has become a problem.

An electronic interlocking device of the matrix data type is
It is easy to associate the required interlocking equipment elements for each train path, which has the advantage of speeding up the interlocking processing time. Since it is not easy to prioritize the processing of the equipment elements, if the alignment becomes complicated and the number of routes increases, it becomes difficult to perform processing such as unlocking of the route lock processed under geographical conditions.

[0007] It is an object of the present invention to solve the above-mentioned problems and to provide an electronic interlocking device which can facilitate the ordering of processing of field devices and enable high-speed interlocking processing in a matrix data system. .

[0008]

According to an aspect of the present invention, there is provided an electronic interlocking device including a storage unit and a processing unit for interlocking field devices with route information. The matrix data and data string data are stored, and the matrix data is associated with a track and a field device related to the track, and the data string data is related to the field device for each track. The processing unit receives the route information, performs a linked process in which the processing order of the data string data is added to the matrix data according to the route information, and outputs a linked output. Is what happens.

[0009]

The storage unit stores matrix data in which a route and field devices related to the route are associated with each other, and data string data in which the processing order of the site devices related to each route is associated. Since the linked processing is performed by adding the processing order of the data string data to the matrix data according to the route information, when the route information is input, the related field device is designated by the matrix data, The data sequence data easily complements the order of processing of field devices, which is a drawback of matrix data, and enables high-speed linked processing.

The processing unit 12 receives the on-site device information S2, and performs an interlocking process for unlocking based on the on-site device information S2 of the on-site device according to the processing order of the data string data D3.
For example, unlocking of a pathway lock and unlocking of an approach lock are performed. For this reason, if the state of the track circuit according to the order of the data string data D3 is confirmed, that is, if the presence or absence of a train in the corresponding track circuit is confirmed, the train can be tracked, and the unlocking can be performed at a high speed. .

Hereinafter, description will be made assuming a specific linear shape.

3 to 7 are diagrams showing the concept of matrix data and data string data stored in the storage unit based on the interlocking chart of FIG. The interlocking chart is well known to those skilled in the art and will not be described.

FIG. 3 shows a pivotal lock matrix. The vertical axis indicates the path name of the interlocking chart, and the horizontal axis indicates the switch in the lock column of the interlocking chart. The state “1” indicates a stereotactic lock, and the state “0” indicates that there is no lock relation. In the case of the route name 1RA, it is indicated that the switches 51 and 52 are locked in a fixed position.

FIG. 4 shows a signal control matrix.
The vertical axis indicates the path name in the interlocking chart, and the horizontal axis indicates the track circuit name in the signal control column of the interlocking chart. The state "1" indicates a condition for displaying the stop announcement. In the case of the route name 1RA, when the train enters the track circuit 51T, the entrance signal 1
The RA is changed to "red" to indicate the stop of the subsequent train, and "red" is displayed until the train advances through the track circuit 1RAT on the route of the track circuits 51T, 52T and 1RAT.

FIG. 5 shows a track lock matrix.
The vertical axis indicates the path name in the interlocking chart, and the horizontal axis indicates the track circuit name in the path lock column of the interlocking chart. State "1" indicates a condition in which after the train has entered the inside of the course, even if the signal lever is restored, the switch cannot be changed until the train has passed through the relevant track circuit. In the case of the route name 1RA, it indicates that the switch 51 cannot be changed until the train advances through the track circuit 51T, and indicates that the switch 52 cannot be changed until the train advances through the track circuit 52T. .

FIG. 6 shows an approach lock matrix.
The vertical axis indicates the path name of the interlocking chart, and the horizontal axis indicates the track circuit name in the approach lock column of the interlocking chart. The state “1” indicates that the traffic light indicates the progress (indicating “blue”) and that the train enters a certain section outside the traffic light, or that the train is outside a certain section outside the traffic light. When the train enters the traffic light and gives a signal to instruct the driver to proceed, the train enters inside the signal or until the stop signal is displayed at the signal and a considerable amount of time elapses Indicates a condition for locking such that a switch or the like on the course cannot be changed. In the case of the route name 1RA, an approaching section is set as a fixed section up to 2T down the track circuit.

In FIG. 2, the simplest linear shape is selected for the sake of simplicity of explanation. Therefore, when the elements of the state "1" in each column are extracted from left to right in the track lock matrix, the track The processing order of the field devices in the lock processing can be obtained. However, if the alignment becomes complicated and the number of routes increases, the order cannot be obtained accurately, and data string data D3 as shown in FIG. 7 is required.
