Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic interlocking device,
More specifically, the support device automatically creates an interlocking database for interlocking processing based on the interlocking table and wiring diagram data for each interlocking control system, and the main device for each interlocking control system through the local area network. Receives the interlocking database, determines the interlocking processing condition of the selected interlocking control system by receiving the complement of the interlocking database of the selected interlocking control system,
The present invention relates to a technique for generating an interlocking output according to route information, improving the versatility of a main device, achieving a reduction in software creation time, and facilitating the work of changing an interlocking control system.

[0002]

2. Description of the Related Art Conventional electronic interlocking devices correspond to different interlocking functions at each station. Therefore, interlocking functions unique to each station are separated as interlocking data, and an interlocking processing program (standard program) refers to the interlocking data. It is configured to perform interlocking processing, and is trying to standardize the software of the electronic interlocking device. The interlocking data is manually created based on the interlocking chart and written in the EPROM. In addition, the electronic interlocking device is a display control panel that shares a part of the interlocking data,
Connected with related equipment such as CTC station equipment, automatic control equipment,
The functions are being improved. Even with these devices, the interlocking data is created manually based on the interlocking chart, and
Written in PROM. When the interlocking chart is changed due to a route change or the like, the interlocking data of all the devices are changed and the EPROM is replaced.

[0003]

However, the conventional electronic interlocking device has not solved the following problems. (A) When the constituent elements of the interlocking control system are changed, the interlocking data must be manually recreated, which requires a long time to create the interlocking data. Moreover, since the interlocking data is manually created based on the interlocking chart according to a certain notation standard, only a person who is familiar with the interlocking chart can create the interlocking data. Therefore, it takes a long time to create the software. (B) Display control panel that uses common interlocking data, C
Interlocking data for related devices such as TC station devices must also be manually created individually, and if the components of the interlocking control system are changed, it takes a long time to create the interlocking data for each device. . In addition, the data management and version management of each device is left to each creator, and even if the interlocked data that executes the same process is created, it is possible that the interlocked data with a different structure is processed depending on the individuality of the creator. As a result, the overall quality of software deteriorates each time the components of the interlocking control system are changed. (C) In order to replace the EPROM when changing the interlocking control system, the power must be turned off once. Once the system goes down, the railroad crossings in or near the station are operating using the interlocking condition, so that an incorrect alarm, a lowering of the breaker, etc. will be performed. Therefore, the EPROM
At the time of replacement, a level crossing guard must be dispatched to each level crossing. Also, because the system goes down, the change work is limited to the time zone from the last train to the first train at night. (D) The operation confirmation of the program after the change before the change of the interlocking control system is accompanied by the above-mentioned time limit and the EPROM replacement work, and therefore the confirmation work of the interlocking control system before and after the change is necessary. It is difficult to secure time for subsequent operation confirmation work.

A first object of the present invention is to provide an electronic interlocking device which enables automatic creation of an interlocking database, shortens software creation time, and can perform change work without bringing down the system.

A second object of the present invention is to provide an electronic interlocking device capable of shortening the time for creating software of each device and making the quality of software among the devices uniform.

Since the interlocking process condition is determined, the interlocking process of the interlocking control system before and after the change can be executed without replacing the EPROM, and the interlocking control system can be easily changed.

Since the main device receives the route information and generates the interlocking output according to the route information, the field equipment can perform an appropriate interlocking process based on the interlocking output.

The different parts are complemented by the interlocking database, and the main processing part can be shared. Therefore, by inputting the interlocking database having the same data structure, comprehensive software is completed, and the software creation time can be shortened.

It is possible to automatically and easily create a linked database having the same data structure according to the above.

In the main unit 2, the storage unit 21 stores the interlocking databases D1 and D2, and the main processing unit 22 receives the complement of the interlocking databases D1 and D2 to determine the interlocking processing condition of the interlocking control system. Therefore, different parts of each interlocking control system are complemented by the interlocking databases D1 and D2, and the main processing unit 22 can be shared.

FIG. 3 is a concrete interlocking chart in the first embodiment of the electronic interlocking device according to the present invention. The symbols in the interlocking chart and the interlocking conditions are well known to those skilled in the art, and a description thereof will be omitted. This interlocking chart refers to Figure 9.59, page 415 of "Signal" (co-authored by Hiroshi Yoshimura and Saburo Yoshikoshi), which is bible for railway signal engineers.

FIG. 4 is a flowchart showing the processing procedure of the support device. The support apparatus 1 creates the interlocking database D1 of the current interlocking control system and the interlocking database D2 of the interlocking control system after the change through the 8-step processing. Hereinafter, the processing content will be specifically described by taking as an example the case of creating the interlocking database D1 of the current interlocking control system.

The "interlocking table input editor" process inputs and edits interlocking table data and creates an interlocking table text file. When inputting the interlocking table data, the symbols described in the interlocking table are divided into the minimum units required for lexical analysis and syntactic analysis and input. Terms are ASCII code, JIS
The first level and the second level are used.

FIG. 5 is a diagram showing a concrete input procedure of the interlocking table data of FIG. The figure shows the concept of the input procedure for the top traffic signal in the interlocking table data. Reference sign a
The symbol indicated by means the beginning of a sentence. Reference sign b means that the name is “traffic light”. The symbol indicated by the reference sign c means a "delimiter".
Reference sign d means data whose starting point is “Tokyo”. The reference sign e means data whose end point is the “downline main line”. The reference sign f indicates that the number of the traffic light is “1R”.
Means data that is. Reference sign g means data in which the rolling device for locking is "7". The reference sign h is
It means the data that the signal control is performed by the track circuits "7T" and "1RT (6I T but 6)". Reference sign i means the data that the path locking is performed by the track circuit "7T". Reference numeral j means data that the approach locking is performed by the track circuits "down 2T" and "down 1T". Reference signs k, m, and n indicate symbols used when the access lock has a time element, and the reference sign l
Means data having an approximate prime time of “90” seconds. The symbol indicated by reference sign o means the end of the sentence.
To facilitate the input of interlocking table data, it is advisable to enter a delimiter in the interlocking table. Thereafter, when the interlocking table data is similarly input, the interlocking table text file is obtained.

The "interlocking table / name primary file generation" process performs lexical analysis, syntactic analysis and semantic analysis of the interlocking table text file to generate an interlocking table primary file and a name primary file.

In the lexical analysis, in order to facilitate syntactic analysis, the contents of the interlocking table text file are converted into token strings in units of interlocking table number fields to create an interlocking table token file. The token includes a reserved word part, a constant part, and a delimiter part. The reserved word portion is composed of an on-site traffic light, a departure traffic light, a turning device, and the like. The constant part is composed of integer constants and character string constants. The delimiter symbol portion is composed of reference numerals a, c, k, n, o and the like in FIG. For example, in the case of the reference sign g in FIG. 5, the reserved word part is the “roller”, the constant part is the integer constant “7”, and the delimiter part is the reference sign c in FIG.

The syntactic analysis reads the interlocking table token file, analyzes how the interlocking table statement is configured, and finds a syntax error. If a syntax error is found, correct the linkage table token file.

The semantic analysis reads the interlocking table token file and checks the rationality in units of one path (one statement). For example, the presence / absence of the same name which is not allowed in one statement is checked, the track circuit name related to the route lock, etc. is checked.

If the semantic analysis is normal, the interlocking table primary file is generated based on the interlocking data that is made meaningful by the token. FIG. 6 is a diagram showing an image of the interlocking table primary file. The interlocking table primary file is an array table in which the interlocking elements related to the route are associated with each other, and is subdivided from each column of the interlocking table in order to have versatility.

The name primary file is a file in which the interlocking table primary file is read and is compiled for each type of interlocking element such as a traffic signal and a turning device.

In the "geographic data primary file generation" process, the geographical configuration (positional relationship) data of the wiring diagram is input and a geographical data primary file is generated.

FIG. 7 is a diagram showing an example of the structure of geographical data. The own data declares what the element is, and if the element is a traffic signal "1R", then "1R"
Is specified. Upside down, upside down, upside down, upside down,
The lower right side of the inverted position shows other elements connected in the direction in which the branch of the troll device is located. The localization side / left side and the localization side / right side indicate other elements connected to the left and right of the element. As for the track circuit including its own data, when the element is a troller, the track circuit including the troller is designated.

FIG. 8 is a diagram showing a concrete input procedure of geographical data. The wiring diagram is shown by extracting the portions of the on-site signal device "1R" and the rolling device "7" of the interlocking diagram of FIG. In the case of the traffic signal "1R", the localization side / left side is "downhill 1T", and the localization side / right side is "7T". In the case of the turning device "7", the localization side / left side is "down 1T", the localization side / right side is "7T", the inverted lower left side is "6IT", and the track circuit including its own data is "7T". Becomes For this reason, the arrangement relationship of each element can be reproduced by connecting the same signs.

The "interlocking diagram rationality check" process reads the interlocking table primary file and the geographical data primary file and verifies the rationality of both.

The "standard function realization possibility determination" processing reads the interlocking table primary file and determines whether the registered interlocking condition is within the range of the standard function of each system.

In the "name file edit" process, after inputting a name required as interlocking data in addition to the name registered in the interlocking table primary file, re-editing for encoding all names is performed. Field device allocation data that determines the I / O port is also input. Register all coded names as name secondary files.

The process of "coding the interlocking table / geographical data primary file" is performed by the interlocking table primary file and the geographic data 1
Read the next file and according to the name secondary file,
After the data of the interlocking table primary file and the geographical data primary file is coded, it is registered as a finalized file together with the name secondary file.

In the "input production specification outside interlocking diagram" process, in addition to the interlocking data (primary file of interlocking table and primary file of geographical data) described in the interlocking diagram, outside the interlocking diagram necessary for each system data Input and edit the items described in the production specifications, and register as an out-of-figure specification file. The interlocking out-of-table production specifications include the input method of the display control panel 6, the related data of the CTC station device 7, the presence or absence of the automatic control device 8, and the field device
Specify the connection data, etc.

The interlocking table primary file and the geographic data primary file which are coded and registered as the finalized file constitute the interlocking database D1 and include the constant table data D211 to D21m of the main unit 2 and the data string data. I'm out. Therefore, the support apparatus 1 can automatically create the interlocking database by mechanically inputting the interlocking table and the wiring diagram data, and can output the interlocking database having the same data structure. As a result, the time for creating the software of the main device 2 is also shortened.

Field equipment 4 based on interlocking out-of-table production specifications
The interlocking database D1 given to the main device 2 and L
Sent via AN5.

The support device 1 reads the interlocking database D1 and the interlocking database D2 stored in the main device 2,
When the configuration is such that it is converted back to the interlocking diagram, the error location in the interlocking database D1 and the interlocking database D2 can be easily found.

Further, the embodiment shown in FIG. 1 has a display control panel 6 for displaying the operation status. The display control panel 6 uses a CRT display as a display panel and a keyboard as an operation panel instead of the control panel used in the conventional relay interlocking device. The operation panel mainly performs processing such as route setting manually when automatic route setting becomes impossible. The CRT display displays the status of the field equipment at that time. The display control panel 6 has a storage unit 61 and a main processing unit 62. The first storage unit 611 stores the interlocking database D1 transmitted from the support apparatus 1 via the LAN3. The second storage unit 612 stores the interlocking database D2 transmitted from the support apparatus 1 via the LAN3. The interlocking database D1 is constant table data D611 to D61m for rationality check judgment of keyboard operation and display editing.
Used to create. Similarly, the interlocking database D2 is used to create the constant table data D621 to D62m. The main processing unit 62 receives the complement of the interlocking database D1 and the interlocking database D2, performs the processing regarding the course setting, and outputs the set course as the course information S1. The process relating to the route setting is, for example, determining whether or not the route to be set can be actually set based on the constant table data D611 to D61m. When it is determined that setting is possible, the set course is output as the course information S1. After setting the route, the situation of the field device 4 is displayed based on the result of the interlocking process performed by the main device 2.

As described above, in the display control panel 6 (related device), the storage unit 61 stores the interlocking database D1 and the interlocking database D2, and the main processing unit 62 receives the interlocking database D1 and the interlocking database D2. Since the process related to the route setting is performed by the interlocking database D1 and the interlocking database D2, the main processing unit 62
Can be standardized. Therefore, by inputting the interlocking database D1 and the interlocking database D2 having the same data structure, comprehensive software is completed, and the time for creating the software of the display control panel 6 can be shortened. Also, the main device 2
Since the display control panel 6 completes the software with the interlocking database D1 and the interlocking database D2 having the same data structure, the quality of the software of each device can be made uniform.

In the storage unit 61, the first storage unit 611 stores the interlocking database D1 of one interlocking control system (current interlocking control system), and the second storage unit 612 stores another interlocking control system (after change). Interlocking control system) of the interlocking control system), and the main processing unit 62 interlocks the interlocking control system selected by receiving the complement of the interlocking control system D1 or the interlocking database D2 selected by the selection signal S3. Since the processing condition is decided, the interlocking process of the interlocking control system before and after the change can be executed without replacing the EPROM, and the interlocking control system can be easily changed.

In the display control panel 6, the main processing unit 62 receives the complement of the interlocking database D1 or the interlocking database D2 to perform the processing regarding the course setting, and outputs the set course as the course information S1. It becomes possible to output the route information S1 after determining whether or not the route to be set can be actually set, and the main device 2 which has obtained the route information S1 can perform highly reliable interlocking processing.

The LAN 3 is a line connecting the support device 1 and the display control panel 6, and the storage unit 61 has at least two storage units 611 and 612. Therefore, the main processing unit 62 is provided.

Conversely, the same applies when returning from the changed interlocking control system to the current interlocking control system. For this reason, it is not necessary to bring down the system for the work of replacing the EPROM, the confirmation work becomes easy, and a sufficient confirmation time can be secured.

In the embodiment shown in FIG. 1, the support device 1 uses the interlocking database D1 and the interlocking database D2 to generate a plurality of constant table data D611 to D61m and a constant number table data D6 required for each standard interlocking process of the display control panel 6.
