2. Description of the Related Art Recently, there are many demands for developing a multi-function software system in a short period of time. The need to build new software systems by combining these systems is increasing.

When a new system is to be developed or its functions are to be expanded by combining existing systems, an automatic route control device that stores train schedules and the like and an electronic device that performs a chain between a traffic signal and a switch are used. Often combined with interlocking devices.

However, the existing automatic route control device and the electronic interlocking device often have different input / output data formats and timings as they are, so that a new system must be developed or an interface must be newly developed each time. In many cases, we had to develop.

[0005] If a new system is developed each time a connection is made, it takes a lot of man-hours to make a connection. Also, when developing an interface, the automatic route control device requires confirmation information as to whether or not information output has ended normally. Since the transmission and reception of information takes a complicated procedure such as the necessity, it cannot be connected with a simple interface, and the development man-hour and cost are increased.

The present invention has been made in order to solve the above-mentioned disadvantages. By creating control information from route information generated by a route control device and sending the control information to an electronic interlocking device,
An object of the present invention is to obtain a versatile converter that can be connected without changing the configuration of both systems, and to connect both systems at low cost.

FIG. 1 is a block diagram showing an embodiment of the present invention. As shown in the figure, the conversion device 1 is an automatic route control device 2
And the electronic interlocking device 3.

The automatic route control device 2 stores train schedules and the like, and outputs route information such as a route number and a train number at any time by combining a trained timetable and train approach information. The electronic interlocking device 3 is a device for establishing a certain association between a traffic light and a switch or another traffic light,
Input control information periodically.

The conversion device 1 includes a route information input unit 4, a route information conversion unit 5, a route information file 6, a control information output unit 7, an answer information input unit 8, an answer information collation unit 9, and an answer.
An information editing unit 10 and an answer information output unit 11 are provided.

The route information input unit 4 inputs route information sent from the automatic route control device 2 as needed. When the route information input unit 4 inputs the route information, the route information conversion unit 5 sets a bit set in advance in the control information stored in the route information file 6 corresponding to the route information. Course information file 6
Stores, for example, control information fixed at "4" bytes, and each bit of the control information corresponds to different route information. The control information output unit 7 outputs the control information stored in the route information file 6 to the electronic interlock device 3 at a fixed period different from the read period of the electronic interlock device 3.

An answer information input unit 8 inputs answer information as input confirmation information of control information input from the electronic interlocking device 3. The answer information file 9 stores the answer information input by the answer information input unit 8. The answer information collating unit 10 collates the answer information stored in the answer information file 9 with the control information stored in the route information file 6. The answer information collating unit 10 answers the collation result.
Notify the information editing unit 11. When the answer information editing unit 11 receives a notification from the answer information collating unit 10 that the collation results match, the answer information editing unit 11 edits an OK response, which is an output result indicating that the route information has been output normally, and When receiving a notification from the information matching unit 10 that the matching results do not match, edit the NG response, which is an output result indicating that the control number was not output normally. Further, the answer information editing unit 11 edits the output result based on the collation result of the answer information collation unit 10 and erases the contents of the corresponding control information stored in the route information file 6 at the same time. The answer information output unit 12 outputs the output result of the control information edited by the answer information editing unit 11 to the automatic route control device 2.

Next, after the conversion device 1 configured as described above inputs the route information from the automatic route control device 2,
The operation until the output result of the route information is returned will be described with reference to the flowchart of FIG.

The automatic route control device 2 generates route information such as a route number or a train number at any time by combining a trained train operation pattern and train approach information.
Output to. When the route information input unit 4 of the conversion device 1 receives the route information output by the automatic route control device 2, the route information input unit 4 notifies the route information conversion unit 5 of the input (step S1).
When the route information input unit 4 inputs the route information, for example, if the input route information is "04h", the route information conversion unit 5 sets a bit corresponding to the route information number of the control information stored in the route information file 6, in this case, The "4" bit is set (step S2). Since the route information conversion unit 5 sets a bit corresponding to each route information of the control information stored in the route information file 6, the electronic interlocking device 3 reads a plurality of states of the automatic route control device 2 which occur spontaneously at a time. The date of
It can be converted to a format. Also, by changing the tables inside the automatic route device 2 and the electronic interlocking device 3 and making the numbers of the route information coincide with each other, the compatibility of the information with each other can be maintained.

The control information output unit 7 outputs the control information stored in the route information file 6 to the electronic interlock device 3 at a period different from the read period of the electronic interlock device 3 (step S3). The electronic interlocking device 3 inputs control information at regular intervals. When the output timing of the control information output unit 7 matches the read timing of the electronic interlocking device 3 and the electronic interlocking device 3 normally inputs the control information sent from the control information output unit 7 of the converter 1, the input control The information is returned as answer information as it is. When the answer information is input, the answer information input unit 8 converts the input answer information into an answer.
The information is stored in the information file 9 (step S4). Answer
The information collating unit 10 collates the answer information stored in the answer information file 9 with the control information stored in the route information file 6 (Step S5). The answer information collating unit 10 notifies the collation result to the answer information editing unit 11 (step S6). Further, the answer information collating unit 10 deletes the answer information used for the collation from the answer information file 9. Here, the control information stored in the route information file 6 is output at a period different from the reading period of the electronic interlocking device 3, so that the electronic interlocking device 3 can read the control information.

When the answer information editing unit 11 receives a notification from the answer information matching unit 10 that the matching results match (step S6), the answer result is an output result indicating that the route information has been output normally. Edit the OK response (Step S
7). Also, the answer information editing unit 11 edits the OK response of the control information from the collation result of the answer information collation unit 10 and erases the contents of the corresponding control information stored in the route information file 6 at the same time. Since the corresponding control information stored in the route information file 6 is deleted after the output result is edited, the same information is not retransmitted by mistake.

When the answer information editing unit 11 receives a notification that the collation results do not match (step S6), the answer result N indicates that the control number was not output normally.
The G response is edited (step S8). The answer information editing unit 11 deletes the contents of the corresponding control information stored in the route information file 6.

The answer information output unit 12 sends the output result of the control information edited by the answer information editing unit 11 to the automatic route control device 2 (step S9). The automatic route control device 2 inputs the output result of the route information, and the input output result is NG.
If the response is a response, the route information is resent to the conversion device 1 up to “2” times, for example. If the NG response is returned even after retransmitting "2" times, the automatic route control device 2 outputs an uncontrollable alarm and stops the corresponding column number from automatic control.

It is to be noted that a file for storing the old route information and a change detecting unit for detecting the localization and the inversion of the pointer based on the change of the route information are provided. The information may be output to the electronic interlocking device 3 together with the route information.

Further, in the above embodiment, "4" bytes of control information are used. However, the control information may be lengthened and field information and the like may be output at one time. As a result, the electronic interlocking device 3 can acquire all necessary information at one time, and there is no deviation due to the reading timing of each information, and the processing can be performed quickly and accurately.

In the above embodiment, the control information output unit 7 periodically outputs the control information stored in the route information file 6 to the electronic interlocking device 3. When receiving the output request, the output unit 7 may output the control information stored in the route information file 6. Thereby, the amount of information transmitted and received between the conversion device 1 and the electronic interlocking device 3 can be reduced, and the communication speed can be increased.

[0025]

As described above, according to the present invention, the route information sent from the automatic route control device at any time is input, and the bits of the control information stored in the route information file corresponding to the input route information are set. Since the bits indicating the route number and train number are set in the control information sent to the electronic interlocking device,
Different route information can be sent to the electronic interlocking device at a time, and the difference in format due to the difference in input / output method can be eliminated.

Further, the control information stored in the route information file is periodically output to the electronic interlocking device, and the read timing of the electronic interlocking device is synchronized with the output timing of the control information. Even if the output and input timings of the information are different, the converter can synchronize the timings and transmit and receive the information.

Furthermore, the answer information stored in the answer information file is compared with the control information stored in the route information file, and the output result is edited based on the comparison result, and at the same time, the corresponding control information stored in the route information file is deleted. Therefore, the processed information is prevented from being retransmitted.

Further, the output result of the edited control information is output to the automatic route control device, and the output result of the route information is notified to the automatic route control device. Therefore, the automatic route device can know the output result of the route information. Therefore, it is possible to take a countermeasure when route information such as retransmission cannot be output normally.
