  FIG. 2 is a flowchart illustrating the switching process when an abnormality occurs in the transceiver according to the present embodiment.

When an abnormality occurs in the transmitter / receiver (hereinafter, referred to as an abnormal transmitter / receiver 501), the logic unit 110 has a track circuit (hereinafter, referred to as a switching target track circuit 502) whose communication target is the abnormal transmitter / receiver 501. It confirms whether it does (202 of FIG. 2). If the switching target track circuit 502 does not exist (NO in 202 in FIG. 2), the logic unit ends the process (206 in FIG. 2). If the switching target track circuit 502 exists (YES in 202 in FIG. 2), the logic unit confirms the priority of the switching target track circuit 502 (203 in FIG. 2). If the priority of the switching target track circuit 502 is high (“high” in 203 in FIG. 2), that is, if the switching target track circuit 502 is one of the track circuits (high priority) 104, the logic unit The communication target switching process of the circuit (high priority) 104 is performed (204 in FIG. 2). If the priority of the switching target track circuit 502 is low (“low” in 203 in FIG. 2), that is, if the switching target track circuit 502 is one of the track circuits (low priority) 105, the logic unit The communication target switching process of the circuit (low priority) 105 is performed (205 in FIG. 2). After performing any of these processes, the logic unit ends the process (206 in FIG. 2).

  FIG. 3 is a flowchart showing the communication target switching process of the track circuit (high priority) 104. In this case, since the switching target track circuit 502 is one of the track circuits (high priority) 104, the switching target track circuit 502 is referred to as a track circuit (high priority) 104-p (p is an integer of 1 or more and N or less). To do.

  The logic unit checks whether there are any of the standby transceivers 103 that are not subject to communication, either the track circuit (high priority) 104 or the track circuit (low priority) 105 (302 in FIG. 3). If there is (YES in 302 of FIG. 3), one of them, the spare transceiver 103-r (r is an integer not less than 1 and not more than K) is arbitrarily selected, and is selected as a communication target of the switching target track circuit 502 (308 in FIG. 3), and the communication target switching process of the track circuit (high priority) 104 is terminated (309 in FIG. 3).

  If there is no spare transceiver 103 that does not communicate any of the track circuits (track circuit (high priority) 104) and track circuit (low priority) 105 (NO in 302 of FIG. 3), the logic unit Then, it is confirmed whether there is a transmitter / receiver that any track circuit of the track circuit (low priority) 105 is a communication target (303 in FIG. 3).

  If there is no transmitter / receiver that any track circuit of the track circuit (low priority) 105 is a communication target (NO in 303 in FIG. 3), the logic unit sets the communication target of the switching target track circuit 502 as the communication target. None (305 in FIG. 3), a train control signal for suppressing train entry to the switching target track circuit 502 is transmitted (307 in FIG. 3), and the communication target switching processing of the track circuit (high priority) 104 is performed. The process ends (309 in FIG. 3).

  If any of the track circuits of the track circuit (low priority) 105 is a communication target (YES in 303 of FIG. 3), the logic unit arbitrarily selects one of them. Hereinafter, the selected transceiver is referred to as a switching target transceiver 503. At this time, the track circuit whose communication target is the switching target transceiver 503 is referred to as a cutting target track circuit 504. Since the cutting target track circuit 504 is one of the track circuits (low priority) 105, it is set as a track circuit (low priority) 105-q (q is an integer of 1 or more and less than M).

The logic unit sets the communication target of the cutting target track circuit 504 to be no communication target (304 in FIG. 3), and transmits a train control signal that suppresses the train from entering the cutting target track circuit 504 (306 in FIG. 3). ). Further, the logic unit sets the communication target of the switching target track circuit 502 as the switching target transceiver 503 (308 in FIG. 3), and ends the communication target switching processing of the track circuit (high priority) 104 (FIG. 3). 309).

  FIG. 5 is a diagram illustrating an operation example of switching processing for switching the communication target of the track circuit (high priority) 104 to the standby transceiver 103. FIG. 5 omits the connection lines of each transceiver, switch, and track circuit based on FIG. With reference to the example in FIG. 5, the operation from YES in 302 in FIG. 3 to 308 in FIG. 3 will be described.

  In this case, the logic unit 110 switches the communication target of the switching target track circuit 502 (track circuit (high priority) 104-p) from the abnormality generating transmitter / receiver 501 to the standby transmitter / receiver 103-r. The abnormality transmitter / receiver 501 is assumed to be a regular transmitter / receiver (high priority) 101-p. The track circuit connection destination switch (high priority) 106 connected to the switching target track circuit 502 (track circuit (high priority) 104-p) is the track circuit connection destination switch (high priority) 106-p. The spare transceiver connection destination changeover switch 109 connected to the spare transceiver 103-r is the spare transceiver connection destination changeover switch 109-r.

  Therefore, the logic unit 110 switches the track circuit connection destination changeover switch (high priority) 106-p and sets the communication target of the switching target track circuit 502 (track circuit (high priority) 104-p) to the spare transceiver connection. The destination switch 109-r is set. Thereby, the abnormality occurrence transceiver 501 (the regular transceiver (high priority) 101-p) does not transmit a train control signal to the track circuit or receive a train detection signal from the track circuit. .

  Further, the logic unit 110 switches the spare transceiver connection destination changeover switch 109-r, and sets the communication target of the spare transceiver 103-r to the track circuit connection destination changeover switch (high priority) 106-p.

Thus, the communication target of the track circuit (high priority) 104-p is not necessarily the regular transceiver (high priority) 101-p, and may be one of the standby transceivers 103.

  FIG. 6 is a diagram illustrating an operation example of switching processing for switching the communication target of the track circuit (high priority) 104 to “no target”. FIG. 6 omits the connection lines of each transceiver, switch, and track circuit based on FIG. The operation of 305 in FIG. 3 will be described using the example of FIG. The track circuit connection destination switch (high priority) 106 connected to the switching target track circuit 502 (track circuit (high priority) 104-p) is the track circuit connection destination switch (high priority) 106-p.

The logic unit 110 switches the track circuit connection destination changeover switch (high priority) 106-p, and switches the communication target of the switching target track circuit 502 (track circuit (high priority) 104-p) to no communication target.

  FIG. 7 is a diagram illustrating an operation example of switching processing for switching the communication target of the track circuit (high priority) 104 to the common transceiver (low priority) 102 that is the communication target of the track circuit (low priority) 105. is there. FIG. 7 omits the connection lines of each transceiver, switch, and track circuit based on FIG. With reference to the example of FIG. 7, the operations of YES in 303 in FIG. 3, 304 in FIG. 3, 306 in FIG. 3, and 308 in FIG. The track circuit connection destination changeover switch (low priority) 107 connected to the cutting target track circuit 504 (track circuit (low priority) 105-q) is a track circuit connection destination changeover switch (low priority) 107-q. The switching target transceiver 503 is assumed to be a common transceiver (low priority) 102-q. The regular transceiver connection destination switch 108 connected to the switching target transceiver 503 (the communication target is the regular transceiver (low priority) 102-q) is the regular transceiver connection destination switch 108-q.

  In this case, the logic unit 110 sets the communication target of the disconnection target track circuit 504 (track circuit (low priority) 105-q) to be no communication target by the track circuit connection destination changeover switch (low priority) 107-q. A train control signal that suppresses the entry of the train to the switching and cutting target track circuit 504 (track circuit (low priority) 105-q) is transmitted.

  The logic unit 110 switches the track circuit connection destination changeover switch (high priority) 106-p, and switches the communication target of the switching target track circuit 502 (track circuit (high priority) 104-p) to the regular transceiver connection destination. Switch 108-q is set. Thereby, the abnormality occurrence transceiver 501 (the regular transceiver (high priority) 101-p) does not transmit a train control signal to the track circuit or receive a train detection signal from the track circuit. .

  The logic unit 110 switches the communication target of the switching target transmitter / receiver 503 (the communication target is the normal transmitter / receiver (low priority) 102-q) to the track circuit connection destination switch ( Switch to high priority 106-p.

As described above, the communication target of the track circuit (high priority) 104-p is not necessarily the regular transceiver (high priority) 101-p, but any one of the regular transceivers (low priority) 102. There is a case.

  FIG. 4 is a flowchart showing the communication target switching process of the track circuit (low priority) 105. In this case, since the switching target track circuit 502 is one of the track circuits (low priority) 105, the switching target track circuit 502 is referred to as a track circuit (low priority) 105-q (q is an integer between 1 and M). To do.

  The logic unit checks whether there are any of the standby circuits 103, which are the track circuits (high priority level) 104 and the track circuit (low priority level) 105 (402 in FIG. 4). If there is (YES in 402 of FIG. 4), one of them, the spare transmitter-receiver 103-s (s is an integer not less than 1 and not more than K) is arbitrarily selected, and is selected as the communication target of the switching target track circuit 502 (404 in FIG. 4), and the communication target switching process of the track circuit (low priority) 105 is terminated (406 in FIG. 4).

If there is no spare transceiver 103 which does not communicate any of the track circuits (high priority) 104 and track circuit (low priority) 105 (NO in 402 of FIG. 4), the logic unit Then, the communication target of the switching target track circuit 502 is set to be no communication target (403 in FIG. 4), and a train control signal for suppressing the entry of the train to the switching target track circuit 502 is transmitted (405 in FIG. 4). The communication target switching process of the circuit (low priority) 105 is terminated (406 in FIG. 4).

  FIG. 8 is a diagram illustrating an operation example of switching processing for switching the communication target of the track circuit (low priority) 105 to the standby transceiver 103. FIG. 8 omits the connection lines of each transceiver, switch, and track circuit based on FIG. With reference to the example in FIG. 8, the operation from YES in 402 in FIG. 4 to 404 in FIG. 4 will be described. In this case, the logic unit 110 switches the communication target of the switching target track circuit 502 (track circuit (low priority) 105-q) from the abnormality generating transmitter / receiver 501 to the standby transmitter / receiver 103-s. The abnormality transmitter / receiver 501 is assumed to be a regular transmitter / receiver (low priority) 102-q. The track circuit connection destination switch (low priority) 107 connected to the switching target track circuit 502 (track circuit (low priority) 105-q) is a track circuit connection destination switch (low priority) 107-q. The spare transceiver connection destination changeover switch 109 connected to the spare transceiver 103-s is the spare transceiver connection destination changeover switch 109-s. The regular transceiver connection destination changeover switch 108 connected to the abnormality occurrence transceiver 501 (the regular transceiver (low priority) 102-q) is the regular transceiver connection destination changeover switch 108-q.

  The logic unit 110 switches the track circuit connection destination switching switch (low priority) 107-q, and switches the communication target of the switching target track circuit 502 (track circuit (low priority) 105-q) to the spare transceiver connection destination. Switch 109-s. The logic unit 110 switches the common transceiver connection destination changeover switch 108-q so that the connection target of the abnormality-occurring transceiver 501 (the common transceiver (low priority) 102-q) is no communication target. Thereby, the abnormality occurrence transceiver 501 (the regular transceiver (low priority) 102-q) does not transmit a train control signal to the track circuit or receive a train detection signal from the track circuit. .

Further, the logic unit 110 switches the spare transceiver connection destination changeover switch 109-s, and sets the communication target of the spare transceiver 103-s to the track circuit connection destination changeover switch (low priority) 107-q. Thus, the communication target of the track circuit (low priority) 105-q is not necessarily the regular transceiver (low priority) 102-q, and may be one of the standby transceivers 103.

  FIG. 9 is a diagram illustrating an operation example of switching processing for switching the communication target of the track circuit (low priority) 105 to “no target”. FIG. 9 omits the connection lines of each transceiver, switch, and track circuit based on FIG. The operation from 403 to 405 in FIG. 4 will be described with reference to the example of FIG. In this case, the logic unit 110 switches the communication target of the switching target track circuit 502 (track circuit (low priority) 105-q) from the abnormality occurrence transceiver 501 to no communication target. The abnormality transmitter / receiver 501 is assumed to be a regular transmitter / receiver (low priority) 102-q. The track circuit connection destination switch (low priority) 107 connected to the switching target track circuit 502 (track circuit (low priority) 105-q) is a track circuit connection destination switch (low priority) 107-q. The logic unit 110 switches the track circuit connection destination changeover switch (low priority) 107-q, and switches the communication target of the switching target track circuit 502 (track circuit (low priority) 105-q) to no communication target.

The logic unit 110 switches the common transceiver connection destination changeover switch 108-q so that the connection target of the abnormality-occurring transceiver 501 (the common transceiver (low priority) 102-q) is no communication target. Thereby, the abnormality occurrence transceiver 501 (the regular transceiver (low priority) 102-q) does not transmit a train control signal to the track circuit or receive a train detection signal from the track circuit. .

In the present embodiment, when there is no common transceiver (low priority) 102 or spare transceiver 103 that can be switched as a communication target of the switching target track circuit 502 (NO in 303 in FIG. 3, 402 in FIG. 4). NO), the logic unit sets the communication target of the switching target track circuit 502 to be no communication target (305 in FIG. 3 and 403 in FIG. 4), and outputs a train control signal that suppresses the train from entering the switching target track circuit 502. Although it is transmitting (307 in FIG. 3 and 405 in FIG. 4), a train control signal for suppressing the entry of the train to the switching target track circuit 502 without making the communication target of the switching target track circuit 502 no communication target. You can just send it.

The priority of the common transceiver in this embodiment is high and low, but may be three or more. In the case of three or more types, the spare transceiver can be substituted for all the regular transceivers, and the low-priority regular transceiver may be substituted for the high-priority regular transceiver. .

According to the present embodiment, since the common transceiver (low priority) 102 can be substituted for the common transceiver (high priority) 101, the number of spare transceivers 103 can be reduced. For example, when the normal transceiver (high priority) 101 that is the communication target of the track circuit (high priority) 104 that has a fatal effect on operation fails, and there is no spare transceiver 103 that can be used, Switching the common transceiver (low priority) 102, which is the communication target of the track circuit (low priority) 105, which does not have a fatal influence on the operation, as an alternative to the above-mentioned common transceiver (high priority) 101 Therefore, it has an advantage that the system can be operated at a minimum without downing the system.

  Hereinafter, another embodiment of the present invention will be described with reference to FIG.

  In this embodiment, a maintenance terminal 1001 is added to the embodiment shown in FIG.

A control instruction to the connection destination changeover switch 109 is issued.

  The logic unit 110 periodically or when the switching state changes, the track circuit connection destination switch (high priority) 106, the track circuit connection destination switch (low priority) 107, the common transceiver connection The switching status of the destination changeover switch 108 and the spare transceiver connection destination changeover switch 109 is transmitted to the maintenance terminal 1001.

  When there is a switching target track circuit 502 that suppresses the entry of a train, the logic unit 110 transmits information on the switching target track circuit 502 to the maintenance terminal 1001.

When the logic unit 110 receives a control instruction from the maintenance terminal 1001, the track circuit connection destination changeover switch (high priority) 106, the track circuit connection destination changeover switch (low priority) 107, and the common transceiver connection destination change according to the control instruction. The switch 108 and the spare transceiver connection destination changeover switch 109 are controlled.

When there is no communication target of the first communication target 1101 of the changeover switch, an end point of the first communication target 1101 of the changeover switch and FIG. 1106 indicating that there is no communication target of the changeover switch are connected by a line (FIG. 11 ( a)). When the communication target of the first communication target 1101 of the changeover switch is the third communication target 1103 of the changeover switch, the end point of the first communication target 1101 of the changeover switch and the end point of the third communication target 1103 of the changeover switch are lined up. Are connected and displayed ((b) of FIG. 11). The same applies when the communication target of the first communication target 1101 of the changeover switch is the second communication target 1102 of the changeover switch, the fourth communication target 1104 of the changeover switch, and the fifth communication target 1105 of the changeover switch. . Further, when a switching instruction is input to the changeover switch 1100 to the maintenance terminal 1001, a communication target is selected by a GUI (Graphical User Interface).

  FIG. 12 is an example in which the maintenance terminal 1001 displays this configuration. The u-th of the track circuit (high priority) 104 (track circuit (high priority) 104-u, u is an integer between 1 and 2) is defined as a track circuit (high priority) u, and a common transceiver (high priority) ) 101 (usual transceiver (high priority) 101-u) is defined as a common transceiver (high priority) u.

  The u th (track circuit (low priority) 105-u) of the track circuit (low priority) 105 is the track circuit (low priority) u, and the u th (common transmitter / receiver) of the common transceiver (low priority) 102. Let (low priority) 102-u) be a regular transceiver (low priority) u.

  When all the devices are normal, the track circuit (high priority) 104-u targets the common transceiver (high priority) 101-u and the track circuit (low priority) 105-u is the regular transceiver. (Low priority) 102-u is a communication target, and the spare transceiver 103-1 is not a communication target.

  106-u in FIG. 12 indicates that the track circuit (high priority) 104-u uses the common transceiver (high priority) 101-u as a communication target.

  The track circuit (low priority) 105-u is intended for communication with the common transceiver (low priority) 102-u, and the track circuit connection destination changeover switch (low priority) 107-u in FIG. This is indicated by a device connection destination changeover switch 108-u.

  The standby transmitter / receiver connection destination changeover switch 109-1 in FIG. 12 indicates that the standby transmitter / receiver 103 has no communication target.

  FIG. 13 is a display example of the maintenance terminal 1001 when an abnormality has occurred in the regular transceiver (low priority) 102-2. When an abnormality occurs in the common transceiver (low priority) 102-2, since there is no track circuit that communicates with the standby transmitter / receiver 103-1, the logic unit 110 includes the track circuit (low priority) 105-2. In order to set the communication target of the standby transmitter / receiver 103-1, the communication target of the track circuit connection destination changeover switch (low priority) 107-2 is set to the standby transmitter / receiver connection destination changeover switch 109-1, The communication target of the changeover switch 109-1 is the track circuit connection destination changeover switch (low priority) 107-2. Further, in order to eliminate the communication target of the common transceiver (low priority) 102-2, the communication target of the common transceiver connection destination changeover switch 108-2 is nullified.

  After that, when it becomes necessary to disconnect the common transceiver (high priority) 101-2 for maintenance, the maintenance staff uses the maintenance terminal 1001 to perform preliminary transmission / reception of the communication target of the track circuit (high priority) 104-2. An example is shown in which the communication target of the track circuit (low priority) 105-2 is set to be no communication target in the device 103-1. In the state of FIG. 13, in order to eliminate the communication target of the track circuit (low priority) 105-2, the communication target of the track circuit connection destination changeover switch (low priority) 107-2 is cleared. The communication target of the spare transceiver connection destination changeover switch 109-1 is set to the track circuit connection destination changeover switch (high priority) 106-2. The communication target of the track circuit connection destination changeover switch (high priority) 106-2 is set to the spare transceiver connection destination changeover switch 109-1.

In the state of FIG. 12, since the communication target of “track circuit (high priority) 1” is “common transceiver (high priority) 1”, column “A” indicating “track circuit (high priority) 1”. "And" Connected "are displayed in the column where the row" 1 "indicating" common transceiver (high priority) 1 "intersects. The same applies to other track circuits and transceivers. Each track circuit has its transmitter / receiver as a communication target, and the logic unit 110 does not inhibit the train entry to the track circuit, and therefore displays “appropriate” in each track circuit column. Since all the transceivers are normal, “normal” is displayed in the row of each transceiver. Since “ordinary transceiver (high priority) 1” and “common transceiver (high priority) 2” cannot communicate with other track circuits, “substitution impossible” is displayed in each line. “Common transceiver (low priority) 1” and “Common transceiver (low priority) 2” are communication targets of the track circuit, and other track circuits can be set as communication targets. “Alternative possible *” is displayed on each line. A transmitter / receiver with a display of “alternatively possible *” can make another track circuit a target of communication, but in that case, communication with the track circuit that is already the target of communication becomes impossible. No trains can enter.
Since the spare transmitter / receiver is not subject to the communication of the track circuit, and other track circuits can be set as the communication target, “Alternative possible” is displayed in the row.

  FIG. 16 is a display example in which the maintenance terminal 1001 indicates the state of the track circuit and the transceiver and the communication target in the state of FIG. Since an abnormality has occurred in “common transceiver (low priority) 2”, “abnormal” is displayed in the row. Furthermore, since “ordinary transceiver (low priority) 2” cannot communicate with another track circuit, “substitution impossible” is displayed in that line. Since “track circuit (low priority) 2” targets the spare transceiver 103-1 as a communication target, “connection” is displayed in the column where the column of “common transceiver (low priority) 2” and the spare transceiver row intersect. Is displayed.

  FIG. 17 is a display example in which the maintenance terminal 1001 indicates the state of the track circuit and the transceiver and the communication target in the state of FIG. Since there is no communication target of “track circuit (low priority) 2”, “connection” disappears from the column of “track circuit (low priority) 2” and “entry impossible” is displayed. Since the communication target of “track circuit (high priority) 2” is the spare transceiver 103-1, “connection” is displayed in the column where the column of “track circuit (high priority) 2” and the row of the spare transceiver intersect. indicate.

According to the present embodiment, the maintenance terminal 1001 can easily identify which transmitter / receiver is used as the communication target of the track circuit, and either the track circuit (high priority) 104 or the track circuit (low priority) 105. When there is no spare transmitter / receiver 103 that is not a communication target, the regular transmitter / receiver 102 (low priority) 102 or the standby transmitter / receiver 103 that can be switched as a communication target can be easily understood. Furthermore, the maintenance terminal 1001 can easily find a track circuit that suppresses the entry of a train.

In these embodiments, the changeover switches (track circuit connection destination changeover switch (high priority) 106, track circuit connection destination changeover switch (low priority) 107, regular transceiver connection destination changeover switch 108, and The spare transmitter / receiver connection destination change-over switch 109) does not have to be independent, and may be integrated as long as it satisfies the functions of this embodiment.

The control (302 in FIG. 3, 402, 404 in FIG. 4) is eliminated. When an abnormality occurs in the common transceiver (high priority) 101 to be communicated by the track circuit (high priority) 104, the communication circuit of any of the track circuits (low priority) 105 is set to be none, and the track circuit By setting the common transceiver (low priority) 102 that the (low priority) 105 is the communication target to be the communication target of the above-described track circuit (high priority) 104, the track circuit (high priority) 104 is controlled. Can continue.

  Furthermore, the logic unit 110 and the maintenance terminal 1001 may not be provided. In that case, the track circuit connection destination switch (high priority) 106, the track circuit connection destination switch (low priority) 107, the regular transceiver connection destination switch 108, or the spare transceiver connection destination switching. The switch 109 is manually switched to perform a switching process when an abnormality occurs in the transceiver.

  When the train entry to the track circuit (track circuit (high priority) 104 or track circuit (low priority) 105) without communication is manually inhibited by operation, the train entry is inhibited. The process (307 in FIG. 3 and 405 in FIG. 4) for transmitting the train control signal may be omitted.
