BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to data of an interlocking database, which is composed of a geographical data file and an interlocking table file, and which is centrally managed, and which is provided with a traffic signal, a turning device, The present invention relates to an interlocking data processing device in an electronic interlocking system that is interlocked and controlled by a CPU for each function of interlocked control such as a track circuit.

[0002]

2. Description of the Related Art An interlocking device is used in a target area such as a railway station yard to secure a safe course of a train and a vehicle.
What has been a relay interlocking device in the past is now an electronic interlocking device, and a large-scale electronic interlocking system has been built.

That is, in a railway station yard, in a place where tracks are complicatedly gathered and branched, a route such as a turning device, a traffic light, and a sign is opened or closed to see whether or not the route can be entered. There are many devices to display,
These are switched according to arrivals, departures, passages, etc. of trains and maintenance vehicles to open the route required by the trains. Switching operations must be carried out promptly and appropriately in response to arrival, departure, passage, etc. of trains, and trains must be operated and passed efficiently.

In order to perform them, in the electronic interlocking system, the route setting is performed by using the start / end lever push buttons or the dedicated keyboard, and the route competition of trains and the locking of the rolling device are programmed by software. To do. Each target area has its own specific layout and equipment, and when there is a change due to equipment modification or update, create specific interlocking data for the target area and set it to operate the functions of each place correctly. There is a need to.

Conventionally, in order to create and deploy these interlocking data, (1) interlocking data unique to a station is created while viewing a document, and written in a ROM (read only memory) by a ROM writer, and each function is classified by function. This ROM has been adopted by inserting it into the printed circuit board of the CPU.

(2) In other words, the interlocking data is stored in the ROM, and (3) When changing the interlocking data, the ROM of each function-specific CPU is manually replaced during trains at night. Was.

(4) The data management and version management related to those ROM changes have been entrusted to the operator.

[0008]

However, in such a conventional technique, since (1) data management using a ROM as a medium is performed, the degree of freedom is low, and the preparation of the ROM is complicated and enormous labor is required. However, quick response is difficult and costly. (2) ROM
There is the same problem as the above because the manual work to install or replace the CPU in each function CPU is complicated, and (3) The complicated data management and version management accompanying the ROM change work are in the hands of the operator. Since it is entrusted, the check system becomes complicated and complicated, such as inspecting the whole again to ensure reliability, it is also troublesome here, it is difficult to secure promptness and it is difficult to reduce costs There was a problem.

The present invention has been made by paying attention to the problems of the prior art as described above, and instead of the ROM, the data is centrally managed as a file, which enables quick response and cost reduction. An object is to provide an interlocking data processing device in an interlocking system.

[0010]

The gist of the present invention for achieving the above object is to use data of an interlocking database, which is composed of a geographical data file and an interlocking table file and is centrally managed, for the functions of various places. An interlocking data processing device (10) in an electronic interlocking system which is interlocked and controlled by a CPU, in which functional data to be distributed to various places is generated and integrated from data in the interlocking database to create a functional data file. A creating unit (20) and a function internal data check unit (3) that compares and reverse-converts the data of the function data file with the original data of the interlocking database and outputs the result.
0) and the distributed function data are C for the functions at the above-mentioned places.
A distribution data check unit (40) for comparing and collating the reverse transfer data reversely transferred from the PU with the function data distributed in the function data file, and outputting the result; and a reverse conversion of the reverse transfer data. An interlocking data processing device (10) in an electronic interlocking system, comprising: a data confirmation check unit (50) that compares and collates with the original data of the interlocking database and outputs a result.

[0011]

In the electronic interlocking system, interlocking data created centrally is provided in each function-based CPU, and each location is interlocked and controlled by this interlocking data. The interlocking data is an interlocking database that is composed of geographical data files created from interlocking charts, interlocking table files, etc. and is centrally managed.

The interlocking data processing device (10) generates function data to be distributed to the function CPUs at various places from the data of the interlocking database, and checks the reliability of the distributed function data.

That is, since the interlocking database is a set of data and cannot be delivered as it is, the function data creating section (20) generates and accumulates the function data delivered to each place from the data of the interworking database and functions. Create a data file. The function data file is a set of unique function data for each place, and each function data is distributed to the corresponding function CPU of each place.

When distributing each function data, the function internal data check unit (30) compares the data of the function data file, which has been inversely converted, with the original data of the interlocking database, checks it, and outputs the result. . Further, the distribution data check unit (40) compares the distributed function data with the reverse transfer data that has been reversely transferred from the function CPUs at various places and the original distributed function data of the function data file. Check and output the result.

In addition to the above, the reverse transfer data is reversely converted, and the data confirmation check unit (50) compares and checks the reversely converted data with the original data of the interlocking database which is the main source. Output the result.

The data distributed in this way is repeatedly checked, and an error-free and highly reliable electronic interlocking system can be constructed.
