<Embodiment>
FIG. 1 is a diagram illustrating a configuration of an electronic interlocking device according to an embodiment of the present invention, and particularly illustrates a configuration of a processing unit that executes interlocking processing. As shown in FIG. 1, the electronic interlocking device of this embodiment includes a CPU 1 that controls execution of interlocking processing, a ROM 2 that stores interlocking processing programs, interlocking data, and types of interlocking data (hereinafter referred to as “data types”). A ROM 3 to be stored and a RAM 4 which is a working memory in which the interlocking processing program stored in the ROM 2 and the interlocking data stored in the ROM 3 are developed are configured.

  As shown in FIG. 1, the ROM 3 is divided into ROMs 3a to 3n so as to store a plurality of interlocking data. For example, the ROM 3a stores the first linked data (linked data 1) among the n linked data, and the ROM 3n stores the nth linked data (linked data n). These linked data are divided for each range covered by the chain relationship, and the example of FIG. 1 shows a case where the range covered by the chain relationship is divided into n. Hereinafter, the interlocking data divided for each range covered by the chain relationship is referred to as “partial interlocking data”.

  In addition, the data type stored in the ROM 3 is the test target linked data (or whether the linkage relationship is changed), or is not the test target linkage data (or changed to the linkage relationship). This is an identifier (flag) provided for distinguishing whether or not the data is linked data (that is, current linked data). Specifically, an identifier of “test” is assigned when each piece of partial interlocking data is the interlocking data to be tested, and an identifier of “current” is assigned when the partial interlocking data is current interlocking data.

  FIG. 2 is a diagram for explaining an interlocking process execution address storage area provided in the RAM 4 as a storage area for storing the head address of partial interlocking data to be used. As shown in FIG. 2, the interlocking process execution address storage area is divided into a priority interlocking process execution address storage area 11 and a non-priority interlocking process execution address storage area 12.

  The priority interlocking process execution address storage area 11 is an interlocking process execution address storage area for storing the head address of the partial interlocking data to be preferentially executed. The priority interlocking process execution address storage area 11 is composed of areas 1 to M so that a plurality of addresses can be stored. Yes. The non-priority interlocking process execution address storage area 12 is an interlocking process execution address storage area for storing the start address of partial interlocking data to be executed at a reduced priority. Are configured from area 1 to area P.

  3 and 4 are diagrams showing an example of the interlocking chart. FIG. 3 shows the interlocking chart, and FIG. 4 shows the interlocking table based on the interlocking chart of FIG. In the interlocking diagram shown in FIG. 3, information on the premises wiring of the stop, the traffic light, the switch, the track circuit, and the like are symbolized and expressed. In the interlocking table shown in FIG. 4, the locking conditions and signal control are described in a table format. In the interlocking chart shown in this example, the range covered by the chain relationship can be divided into a range 1 including {1R, 2R, 7R, 8R} and a range 2 including {3L, 4L, 5L, 6L}. In the interlocking table shown in FIG. 4, the portion related to “range 1” is stored in, for example, the ROM 3a, and the portion related to “range 2” is stored in, for example, the ROM 3b (not shown). That's fine.

  Next, the operation of the electronic interlocking device according to the present embodiment will be described with reference to FIG. FIG. 5 is a flowchart for explaining the operation of the electronic interlocking device according to the present embodiment.

  First, in step S101, the counter N is set to the number of ranges when the equipment to be subjected to the interlock test is divided into ranges that are linked. In step S102, 1 is set to the counter n. In step S103, 1 is set to the counter m. In step S104, 1 is set to the counter p. Note that steps S101 to S104 are a flow showing the initial setting process.

  In step S105, the data type of range n is input. In this flow, since the initial value of n is “1”, the first data type in the partial interlocking data divided into n pieces is input, and the second and subsequent data are subsequently counted according to the count up of n. Types are entered sequentially.

  In step S106, on-site equipment information such as the train position related to the range n and the switchover direction is input. In step S107, control information from a traffic signal control console related to the range n is input.

  In step S108, the field device information input last time in the range n is compared with the field device information input this time, and the control information input last time and the control information input this time are compared.

  In step S109, if the comparison result in step S108 matches, that is, the field device information input last time matches the field device information input this time, and the control information input last time matches the control information input this time. If so (step S109, Yes: hereinafter defined as “when input information matches”), the process proceeds to step S112. On the other hand, if the comparison result in step S108 does not match, that is, if at least one of the field device information and the control information does not match (step S109, No: hereinafter defined as “input information does not match”), step The process proceeds to S110. The case where the input information does not match is a case where there is a change or change in any of the input field device information and control information, for example, a case where there is any change in the field device in operation. .

  A storage area for storing input information of each section is provided in, for example, the RAM 4. In step S110, the input information in the range n (previous input information or previous input information is stored) is changed to current input information. In step S111, it is determined whether the data type is current or test. If the data type is current, the process proceeds to step S115. If the data type is test, the process proceeds to step S112.

  In step S112, the head address of the partial interlocking data in the range n is set in the p-th non-priority interlocking process execution address storage area, the value of p is set in pmax in step S113, and the value of p is set in step S114. Increment. That is, in the flow of steps S112 to S114, among the partial interlocking data in the range 1 to n, the data stored in the non-priority interlocking process execution address storage area is classified and stored in the non-priority interlocking process execution address storage area. Count the number of partially linked data. Therefore, the number of partial interlocking data stored in the non-priority interlocking process execution address storage area is stored in pmax after the end of the sorting process for the partially interlocking data in the range 1 to n.

  On the other hand, in step S115, the head address of the partial interlocking data in the range n is set in the m-th priority interlocking process execution address storage area, m is set to mmax in step S116, and m is determined in step S117. Is incremented. That is, in the flow of steps S115 to S117, among the partial interlocking data in the range 1 to n, the data stored in the priority interlocking process execution address storage area is classified and the part stored in the priority interlocking process execution address storage area Count the number of linked data. Therefore, the number of partial interlocking data stored in the priority interlocking process execution address storage area is stored in mmax after the end of the sorting process for the partially interlocking data in the range 1 to n.

  In step S118, the value of n is incremented. In step S119, it is determined whether or not the value of n is greater than N, that is, whether or not all the segmentation processing of the partial interlocking data in the range 1 to n has been completed. If the segmentation processing has not ended (step S119). , No), the process proceeds to step S105, and if completed (step S119, Yes), the process proceeds to step S130.

  In step S130, the value of m is set to 1, and in step S131, the partial interlocking data at the address set in the m-th priority interlocking process execution address storage area is read and executed. In step S133, the value of m is incremented. In step S134, it is determined whether or not the value of m is greater than mmax. If the value of m is equal to or less than mmax, step S131 is performed. If the value of m exceeds mmax, the process proceeds to step S135. That is, steps S130 to S134 are a flow for executing processing relating to partial interlocking data stored in the priority interlocking process execution address storage area.

  In step S135, the value of p is set to 1. In step S136, the partial interlocking data at the address set in the p-th non-priority interlocking process execution address storage area is read and executed. In step S137, the process is processed. The result is output to the outside to control the field equipment. In step S138, the value of p is incremented. In step S139, it is determined whether or not the value of p is greater than pmax. If the value of p is less than or equal to pmax. If the value of p exceeds pmax, the entire process is terminated. That is, steps S135 to S139 are a flow for executing processing related to partial interlocking data stored in the non-priority interlocking process execution address storage area.

  FIG. 6 is a chart showing the concept of priority according to the data type. As shown in FIG. 6, when the data type is a test, the priority is kept low regardless of the change in the input information. When the data type is current, the priority level is changed according to whether the input information has changed. Specifically, if there is a change in the input information, it is a case in which the field device information and the control information have changed, so a higher priority is set, and if there is no change in the input information, the field device information and the control are set. Since there is no change in information, the idea is to keep the priority lower than when there is a change in input information. Besides this, for example, in order to set the current priority higher than the test priority, the priority is set to “medium” when the data type is current and the input information has not changed. You may do it. In this case, the highest priority is set when the field device information and the control information change.

  In the flowchart of FIG. 5, the presence / absence of a change in input information is determined and then the current / test of the data type is determined. However, the current / test of the data type is determined, and then the input information You may make it determine the presence or absence of a change.

  FIG. 7 is a time chart for explaining the relationship between the priority level and the execution order in the electronic interlocking device of the present embodiment. In addition, the example shown in FIG. 7 has shown the case where the range which the chain relationship covers in an interlocking chart is four.

  The CPU 1 that controls execution of the interlocking process executes an initial setting process (steps S101 to S104) and a priority determination process (steps S105 to S119) according to the flowchart of FIG. These processes are executed in the initial stage of the process as shown by hatching in FIG. In this example, the priority determination processing determines that ranges 1 and 4 are prioritized (“current” and “input information has changed”), and ranges 2 and 3 are not prioritized (“test” or ““ current ”and "No change in input information")) is determined, and the processing is executed in the order of range 1-> range 4-> range 2-> range 3, and data is output when the processing in each range is completed. In the next cycle, a new determination process is performed, and each range of processes is executed according to the determined priority.

  As described above, according to the electronic interlocking device of the present embodiment, the entire interlocking data is divided into a plurality of partial interlocking data for each range covered by the chain relationship, and a data type is assigned to the partitioned partial interlocking data. Therefore, it is necessary to change the partial interlocking data only for the range related to the chain relationship, and to stop the display of the entire campus. There is no effect.

  In addition, according to the electronic interlocking device of the present embodiment, even if a test is performed on partial interlocking data whose linkage relationship has been changed, it is only necessary to stop a part of the display, Even so, the effect that the test can be performed is obtained.

  In addition, according to the electronic interlocking device of the present embodiment, when the current operation and the test are performed in parallel, the control related to the partially interlocking data of the current operation is preferentially executed. The effect of improving is acquired.

  Further, according to the electronic interlocking device of the present embodiment, when current operation and testing are performed in parallel, priority is given to the case where there is a change in field device information or control information. It is possible to obtain an effect of further improving safety.

  As described above, the electronic interlocking device according to the present embodiment is useful as an invention that enables simple and quick execution of a preliminary test.
