Description

  The present invention relates to an interlocking device for ensuring a safe course of a train on a railway line, and more particularly to an integrated interlocking device that centrally processes interlocking logic over a plurality of stations. The present invention also relates to an integrated interlocking system that includes a station control terminal in addition to such an integrated interlocking device.

Interlocking stations in a single line section are controlled by exclusive control (stereo position lock) between competing departure traffic signals of adjacent linked stations in a single line section, including the entire line section including the middle between linked stations. Concentrated interlocking devices and integrated interlocking devices have been developed (see Patent Document 1, Non-patent Document 1, for example).
These interlocking devices are the basic function of the interlocking device between competing departure traffic lights as a means of constructing the block of single track sections, taking advantage of the processing of centralized interlocking logic across multiple stations. By applying exclusive control (stereo position lock), the direction line in the single line section, the driving direction logic, and the driving handling at both stations are made unnecessary.

However, with such an interlocking device, as the flip side of capturing the entire line area as one interlocking station, each interlocking station and the arrangement between them are specifically the next station (next station, next station). If it is unambiguously determined and fixed, and the field device installed at a certain station in the line becomes abnormal, the closure cannot be configured (secured), and there is a risk of hindering the operation of the entire line. And if it is going to take a redundant structure in order to avoid such a malfunction and to improve operability, the advantage which concentrated by simplifying the interlock logic of a plurality of stations will be lost, and it is difficult to expand the application range.
Therefore, it becomes a problem to realize an integrated interlocking device that can flexibly cope with abnormalities at some stations even if the interlocking logic over a plurality of stations is centrally processed.

  The integrated interlocking device of the present invention (Solution 1) was devised in order to solve such a problem, and the state information of the traffic light, the switch and the track circuit of each station in the railway line section is obtained. In the integrated interlocking device that controls the operation of the traffic light and the switch of each station by acquiring and centrally processing the interlocking logic for each station, the block logic related to a plurality of single line sections in the line section is set for each section. It is characterized by being processed every time. Here, the acquisition of the status information for the traffic light, the switch and the track circuit of each station and the control of the operation for the traffic light and the switch may be performed directly via each device and, for example, an individual signal line. It is more practical to carry out indirectly through each device, for example, a shared transmission path and a control terminal for each station.

  Further, the integrated interlocking device of the present invention (solving means 2) is the integrated interlocking device of the above-described solving means 1, wherein the intermediate logic is processed when processing the block logic relating to the single line section that is adjacent to the intermediate station. When an abnormality is detected in an on-site apparatus at a station, the intermediate station and single-line sections on both sides thereof are handled as one single-line section. Here, the abnormality detection may be performed automatically upon reception of a notification to notify the abnormality or disruption of normal communication, etc., and is performed depending on manpower such as setting input from the display control panel by the operator. However, it is practical to do it with the cooperation of both parties.

The arrival of the train on the arrival line can be detected based on the state information of the track circuit of the arrival line.

  Further, the integrated interlocking device of the present invention (Solution means 4) is an integrated interlocking device of the above-described solving means 1 to 3, and the station on both sides of the single line section is provided with track circuits, but between stations. Is provided with a virtual orbital circuit in logical processing (using a binary logic flag, multi-valued logic data, etc.) corresponding to a special automatic block section in which no track circuit is provided, and the special automatic block section The train entry from the departure station on one end side of the vehicle is approved to enter the virtual track circuit to change the state of the virtual track circuit to a train-on-line state, and to the arrival station on the other end side of the special automatic block section The train entry from the virtual track circuit is authorized by entering the train, and the state of the virtual track circuit is set to the train non-existing state. Further, when processing the closing logic related to the special automatic closing section The above Use of the virtual trajectory circuit as an arrival point for the competing departure signal on the special automatic closing section side at the stations on both sides of the automatic closing section in particular (i.e., the arrival points of competing departure signals are both virtual trajectory circuits, It is characterized in that the closing logic is processed by making the virtual trajectory circuit which is the arrival point an exclusive condition (which departure signal uses first (faster in time)). To do.

  Further, the integrated interlocking device of the present invention (solving means 5) is the integrated interlocking device of the above-mentioned solving means 4, wherein the virtual trajectory is provided for each section in correspondence with the existence of a plurality of the special automatic closing sections. A virtual track circuit for logical processing related to the continuous section corresponding to the fact that there is a continuous section that is two adjacent single-line sections across the intermediate station in the special automatic block section And when the abnormality is detected in the field device of the intermediate station, the state setting of the virtual track circuit and the processing of the closing logic for each of the plurality of special automatic closing sections belonging to the continuing section, Instead of or in preference to it, the state setting of the virtual track circuit related to the continuing section and the processing of the closing logic with the continuing section and the intermediate station as one section are performed. And features. Again, abnormality detection may be performed automatically upon receipt of a notification to notify the abnormality, disruption of normal communication, etc., or may be performed depending on manpower such as setting input by a driver. However, it is practical to do it with the cooperation of both parties.

  Further, the integrated interlocking device of the present invention (solving means 6) is the integrated interlocking device of the above-described solving means 4 and 5, wherein the train entry authorization to the virtual track circuit exists in the train traveling direction at the departure station. A series of track circuits that show the state transitions corresponding to train travel in order, and after a predetermined time for confirmation has passed since the final state transition, the authorization of train advance from the virtual track circuit is The inward first track circuit, which is the first track circuit of the in-field traffic signal on the special automatic block section side at the arrival station, shows the state transition corresponding to train travel, and is performed. . Here, the track circuit indicates the state transition corresponding to the train running means that the track circuit state information becomes a suspended state (operation) state indicating a train non-existing line after being in a falling state indicating the train existing line. Say.

  Further, the integrated interlocking device of the present invention (Solution means 7) obtains the status information of the traffic light, the switch and the track circuit of each station in the railway line section, and centrally processes the interlocking logic for each station. In the integrated interlocking device that controls the operation of the traffic light and the switch at each station, a track circuit is provided on both sides of the single line section, but no track circuit is provided between the stations. A train from a departure station at one end of the special automatic block section, equipped with a virtual track circuit on logical processing corresponding to the special automatic block section (using a binary logic flag, multi-level logic data, etc.) Acknowledging train entry to the virtual track circuit with advancement to make the state of the virtual track circuit a train standing state, and from the virtual track circuit by entering the train to the arrival station on the other end side of the special automatic block section Before the train advancement of Characterized in that it adapted to the state of the virtual track circuit a train non-rail state.

  Further, the integrated interlocking device of the present invention (solving means 8) is the integrated interlocking device of the above-described solving means 7, and the virtual trajectory for each section corresponding to the existence of a plurality of the special automatic closing sections. And a virtual orbital circuit on the logical processing related to the continuous section corresponding to the presence of a continuous section adjacent to the intermediate station in the special automatic block section. When an abnormality is detected in the field device at the intermediate station, the virtual track circuit state setting and block logic processing for each section related to each of the plurality of special automatic block sections belonging to the subsequent section may be replaced or prioritized. Then, the state of the virtual track circuit related to the continuous section is set.

  Moreover, the integrated interlocking system of the present invention (solving means 9) includes the integrated interlocking apparatus of the above-described solving means 1 to 8, the control terminal installed at each station, and the communication between the integrated interlocking apparatus and the control terminal. The control terminal is detected based on the operation information that the operation member for emergency stop provided at the station where the control terminal is installed is operated. The operation information is transmitted to the integrated interlocking device via the transmission line, and a stop signal is displayed on the traffic light at the installation station, and a track circuit including a tipping machine provided at the installation station. Is detected based on the state information of the track circuit, the state information is transmitted to the integrated interlocking device via the transmission path and the switch is locked (unnecessarily converted). The current Positioned fixed) of decided to, characterized in that is adapted to perform that either one or both.

In such an integrated interlocking device of the present invention (Solution means 1), when there are a plurality of single line sections when centralized processing of interlocking logic over a plurality of stations, the blocking logic related to the single line section is present. By processing for each section, when an abnormality occurs in the field device at a station related to any single line section, it is often sufficient to deal with the blocking logic related to the corresponding single line section. The need for extensive allowances across all or many sections rarely occurs.
Therefore, according to the present invention, it is possible to realize an integrated interlocking device that can flexibly cope with abnormalities at some stations even if the interlocking logic over a plurality of stations is centrally processed.

Moreover, in the integrated interlocking device of the present invention (Solution means 2), it is assumed that the block logic related to a normal single line section is processed for each section as described above, and then the field device of the intermediate station. When an abnormality occurs, the middle station and the single-line sections on both sides of the intermediate station are grouped together as one single-line section, and the block logic related thereto is processed, so that the section allocation becomes coarse for that part. However, there is a possibility that the train operation will be delayed due to the degeneracy of the exclusive control unit (the section subject to stereotactic locking), but the train operation management of the entire line area will be maintained and safety will be maintained. Secured.
Therefore, according to the present invention, it is possible to realize an integrated interlocking device that can automatically and flexibly cope with abnormalities at some stations even if the interlocking logic over a plurality of stations is centrally processed.

Further, in the integrated interlocking device of the present invention (Solution means 3), in addition to the construction (securement / locking / establishment) and unlocking (cancellation) of the block related to the single wire section, the accompanying start signal is shown. As for control, the details of processing such as procedures are specified, train operation management is tightened, and safety is improved.
Therefore, according to the present invention, it is possible to flexibly cope with abnormalities at some stations even when centralized processing of interlocking logic over a plurality of stations and to realize a safe integrated interlocking device.

In addition, in the integrated interlocking device of the present invention (solution 4), a virtual trajectory circuit (logical information that simulates the state of the trajectory circuit) on logical processing is provided in correspondence with the special automatic block section, By changing the state of the virtual track circuit according to the train progress status and processing the closing logic with reference to it, it is similar to the known automatic closing method, which is simpler than the known special automatic closing method. Since the block logic can be processed by this method, it is possible to easily perform an abnormality handling treatment related to the block logic.
Therefore, according to the present invention, it is possible to realize an integrated interlocking device that can flexibly and easily cope with abnormalities at some stations even if the interlocking logic over a plurality of stations is centrally processed.

In the integrated interlocking device of the present invention (solution 5), it is assumed that the closing logic related to the normal special automatic closing section is processed for each section with reference to the virtual trajectory circuit. When an abnormality occurs in a field device at an intermediate station, the intermediate station and the special automatic block sections on both sides of the intermediate station are grouped together as a single line section, and the block logic concerned is also processed with reference to the virtual track circuit. By doing so, the section division becomes coarse only by that part, and the preciseness of the exclusive control unit (target section of the position lock) may be reduced, so train delays may occur, but train operation of the whole line section Management is maintained without stopping and safety is ensured.
Therefore, according to the present invention, it is possible to realize an integrated interlocking device that can automatically and flexibly and easily cope with abnormalities at some stations even if the interlocking logic over a plurality of stations is centrally processed.

Further, in the integrated interlocking device of the present invention (solution 6), the virtual track circuit is realized by embodying the authorization conditions for the approval of train entry and train entry into the virtual track circuit corresponding to the special automatic block section. As a result, the train operation management becomes stricter and the safety is improved.
Therefore, according to the present invention, it is possible to realize a safe integrated interlocking apparatus that can flexibly and easily cope with abnormalities at some stations even if the interlocking logic over a plurality of stations is centrally processed.

  In addition, the integrated interlocking device of the present invention (solution means 7 and 8) is obtained by leaving the portion relating to the virtual trajectory circuit from the characteristic part of the above (solution means 4 and 5), and the portion relating to block logic processing. However, it does not directly contribute to the initial problem of “avoiding problems at some stations and improving operability”, but it has the effects that are derived from the solution. For example, by providing the status information of the virtual track circuit to the display panel etc., the display panel etc. can be integrated in the same way as for the section where the track circuit exists even in the section where the track circuit does not exist. Can be grasped.

[Integrated interlocking system of the present invention (solution 9)]
In the integrated interlocking device in which the functions of many interlocking devices installed at each station are concentrated in one interlocking device as in the above solution, communication between the integrated interlocking device and the control terminal installed at each station If it is going to be performed quickly, a high-speed transmission means is needed between them. A specific example of the need for such rapid communication is when an "emergency stop button (train protection switch)" that is handled to stop the train quickly when a passenger falls from the platform to the track. At this time, the operation information is transmitted from the control terminal to the integrated interlocking device. Upon receiving this information, the integrated interlocking device creates control information for displaying the stop signal on the corresponding traffic light. Is transmitted from the integrated interlocking device to the control terminal, and a series of processing is executed in which the corresponding traffic light displays a stop signal. In order to quickly complete the emergency process in such a process, it is necessary that the transmission is performed at a high speed, and optical transmission is usually used.

Also, when a parked or detained vehicle runs away and enters a track circuit that includes a tipping machine, it is necessary to hurry to lock the tipping machine (fixed in a state that is not controlled to the dangerous side). Since the process at that time goes through the same process as described above, high-speed transmission is also required between the integrated interlocking device and the control terminal.
However, the single line section and the special automatic block section to which the integrated interlocking device of the present invention is applied are local lines, and it is a heavy business burden to perform infrastructure development using optical transmission or the like.

  Therefore, in order to cope with a situation that occurs suddenly at the site and the corresponding signal must be made a stop signal as soon as possible, the control terminal is provided with an “emergency stop signal control function” and / or In order to cope with the situation where the relevant machine must be locked as soon as possible, the control terminal is provided with an “emergency lock function”. Thereby, the control terminal provided in each station displays the stop signal by itself and / or locks the switch, regardless of the control from the integrated interlocking device provided in the center. Thereafter, a stop signal and lock control are sent from the integrated interlocking device with a delay. By providing the control terminal with such an emergency stop signal control function and / or emergency lock function, the transmission between the integrated interlocking device and the control terminal can be performed at low speed using an existing metal cable. Because it can be used for transmission, the equipment cost is greatly reduced.

Even if the control terminal does not have an “emergency stop signal control function” or “emergency check lock function”, a stop signal or lock control is sent from the integrated interlocking device to the control terminal. Therefore, although there is a delay in countermeasures, necessary countermeasures are taken, so that the control terminal can be updated sequentially after the introduction of the integrated interlocking device, and the capital investment burden can be distributed and reduced.
Contrary to having the traffic signal indicate a stop signal, the signal density is insignificant because the traffic signal is displayed on the traffic signal because it is a local line. Even if it takes time to display the signal to be displayed, it is allowed. In actual operation, there is no actual harm if a traffic signal setting trigger is output to the integrated interlocking device from the automatic route control device or the display control panel as soon as it takes time.

  The example train operation management system (see FIG. 1) includes a plurality of stations (interlocking stations) A, B,... Belonging to the line area based on the train operation information and train schedule of the line area being processed. Displays automatic route control device (PRC) 2 that outputs the setting trigger of traffic lights to the integrated interlocking device 10 and the field information obtained from each field device such as traffic lights, switchboards, track circuits, etc. Along with the display control panel 3 for the operation handler to input the setting trigger of each traffic light and the abnormality setting / recovery input of the field device and output it to the integrated interlocking device 10, it belongs to the railway line section to be processed The integrated interlocking device 10 that centrally processes the interlocking logic relating to a plurality of stations (interlocking stations) A, B,..., The control terminals 6, 6,. A message that supports the reliable transmission and reception of instructions and information telegrams It has and a road 4.

Among these devices, the control terminal 6 and the integrated interlocking device 10 are railway facilities and have a fail-safe configuration.
The transmission line 4 may be an individual dedicated product, but if a CTC station loop (not shown) or the like is available, it may be diverted, or it may be a low-speed one using a metal cable used from an old facility. But it ’s okay.

  The control terminal 6 is connected to each field device such as a traffic signal in the station station where it is installed, a switch, a track circuit, etc. via a dedicated or shared signal line, etc. , A function that collects status information from each field device such as track circuit, a control output function that controls the operation of each field device such as a traffic light and a switch, in cooperation with the host devices 2 and 10, in an emergency. The function of emergency stop signal control and emergency lock and lock function are shown. The emergency stop signal control function and the emergency lock function may be provided for one control terminal 6 at the same time or at different times, and for a plurality of control terminals 6. However, the control terminal 6 shown in the figure has both functions.

  When the emergency stop button (operating member for emergency stop) provided in the station where the control terminal 6 is installed is operated, the control terminal 6 equipped with the emergency stop signal control function displays the operation information. 6, the operation of the emergency stop button can be detected based on the input of the operation information. When the operation is detected, the operation information is transmitted to the integrated interlocking device 10 via the transmission path 4. Transmitting and stopping at the traffic signal at the station where the control terminal 6 is installed (such as an on-site traffic signal where the train arrives at a platform where an emergency stop button operated at least is installed or a departure signal departing from the platform) The signal is displayed.

  The control terminal 6 equipped with an emergency lock function is used when a vehicle stopped or detained at a station where the control terminal 6 is installed escapes and enters a track circuit including a tipping machine. In response, train track information is sent from the track circuit as status information. Based on the input of the status information, the runaway vehicle is sent to the track circuit including the turning machine installed at the station where it is installed. Intrusion can be detected, and when the detection is made, the status information from the track circuit is transmitted to the integrated interlocking device 10 via the transmission path 4, and is included in the track circuit of the escape vehicle intrusion destination. The locking machine is locked (fixed at the current conversion position so that it is not controlled unnecessarily).

  The integrated interlocking device 10 employs a fail-safe computer as hardware in accordance with the flow of computerization, and each means 11 to 16 that realizes necessary functions is realized by programs and data installed therein. . In other words, the integrated interlocking device 10 includes the station-specific interlocking logic processing means 11, the adjacent station closing logic processing means 12, the near-station closing logic processing means 13, and the adjacent station virtual track circuit logic processing means 14 that function by executing the program. And the near station virtual track circuit logic processing means 15 and the adjacent station near station switching means 16 are provided.

  Each station individual interlocking logic processing means 11 combines the functions of a plurality of electronic interlocking devices that have been distributed and installed in the stations A, B, C,. Therefore, the state information of each field device including the traffic lights of each station A, B, C,..., The turning machine, and the track circuit is acquired via the control terminal 6 and the transmission path 4. In addition, the interlocking logic for each station A, B, C,... Is centrally processed by one device based on the state information, and the traffic lights and switchboards for each station A, B, C,. The operation of each on-site device is controlled via the transmission line 4 and the control terminal 6.

Inter-adjacent station block logic processing means 12 processes block logic related to a single line section. When a plurality of single line sections are included in the processing target, the block processing logic is processed for each section (individual single line section). It is supposed to be.
Here, the adjacent station refers to two stations (A station and B station, B station and C station, C station and D station,...) That are adjacent to each other across each single line section, as seen from the train. Sometimes it refers to a stopped station (departure station) and the next station (arrival station).

The near-station block logic processing means 13 also processes the block logic related to the single line section, but processes the block logic related to the continuous section that is two adjacent single line sections across the intermediate station in the single line section. The intermediate station belonging to the corresponding continued section and the single line sections on both sides of the intermediate station are grouped together as if they were one single line section with a side line station that is not subject to control. The block logic of a single line section (referred to as a single line section when it is clearly distinguished from individual single line sections) is processed.
Here, the near station is two nearby stations (A station and C station, B station and D station, C station and E not shown) that are adjacent to each other across a continuous section that can be regarded as a single section. Station, ...), and when viewed from the train, it refers to the stopped station and the next station.

  Any of these block logic processing means 12 and 13 is configured to process the block logic and configure the block whether the block target section is an individual single line section or a single line section (continuous section). Construct the route of the departure signal on the side of the target block to be closed at the departure station related to (close the route exclusively) and display the signal instructing the progress to make the direction toward the arrival station the direction of the target block The closing structure concerning is performed. Then, due to the blockage configuration, the departure signal on the block target section side at the arrival station related to the block target section is exclusively controlled so that the route cannot be formed, and thus the stop signal continues to be displayed.

  Further, the closing logic processing means 12 and 13 are both closed when processing the closing logic and unlocking the closing regardless of whether the closing target section is an individual single line section or a single line section (continuation section). The departure signal on the side of the target station to be closed at the departure station related to the section showed the signal indicating the progress, the train traveled on the route of this departure signal, and the target train from the final track circuit on this route And that the predetermined time for confirmation, for example, 120 seconds has passed, and that the traffic signal on the side of the block to be closed at the arrival station related to the block to be closed has shown a signal instructing the progress, If it is detected that the train has traveled on the track of the traffic signal and that the train has advanced from the inner first track circuit, which is the first track circuit on this route, in that order, The clogging of between is adapted to unlock.

  Further, along with the closing / unlocking of the block target section by the block logic processing means 12, 13, the interlocking logic of the arrival station related to the block target section is processed regardless of whether the block target section is an individual single line section or a single line section. Then, the control for continuing the display of the stop signal for the departure signal on the side of the section to be closed at the arrival station is stopped. This may be performed by the means 12 and 13 constituting the block, or the station individual link logic processing unit 11 may act on its behalf, but in any case, the arrival line of the arrival station related to the block target section The arrival of the train at (home track) is confirmed based on the status information of the track circuit of the arrival line, etc. ) Is detected based on the status information of the traffic signal, etc., and the control for continuing the display of the stop signal for the departure traffic signal at the arrival station is stopped.

The inter-neighboring station virtual track circuit logic processing means 14 is configured so that each single line section to be closed is a special automatic block section, that is, the station on both sides of the single line section is provided with track circuits. When no track circuit is provided between them, virtual track circuits (virtual track circuits for individual sections) are provided so as to correspond to each special automatic block section one by one.
This virtual track circuit is not actually present on the track, but is based on logical processing that is manifested by the function of the integrated interlocking device 10. For example, the integrated interlocking device 10 has either data or program execution state. Or it exists in the aspect according to both or it.

  Then, the inter-station virtual track circuit logic processing means 14 indicates that the train has advanced from the departure station on one end side of the corresponding special automatic block section for each of the above-described virtual track circuits (virtual track circuits for individual sections). When it is detected based on the status information of the track circuit of the departure station, it is recognized that the train has entered the corresponding virtual track circuit, and the status of the corresponding virtual track circuit is changed to the train standing state. . Further, the inter-adjacent station virtual track circuit logic processing means 14 indicates that the train has entered the arrival station on the other end side of the special automatic block section corresponding to the target virtual track circuit in the status information of the track circuit of the arrival station. When detected based on this, it is recognized that the train has advanced from the corresponding virtual track circuit, and the state of the corresponding virtual track circuit is set to a train non-existing line state.

  Further, based on the introduction of such a virtual track circuit (individual section virtual track circuit), the inter-neighboring station block logic processing means 12 processes the block logic for the single line section of the special automatic block section. The arrival points of competing departure traffic lights on the target section side at both stations of the special automatic closing section to be closed are virtual track circuits, and which departure traffic signal is ahead of the virtual track circuit that is this arrival point (time By using an exclusive condition as to whether or not to use it earlier, the closing logic is processed. Therefore, the interlocking table that embodies the logic of the block processing logic 12 between adjacent stations becomes simple and easy to understand, and can be easily checked and changed.

The near-station virtual trajectory circuit logic processing means 15 determines that the number of special automatic closing sections to be closed is a continuous section adjacent to the intermediate station. Corresponding to each other, a virtual trajectory circuit (referred to as an extended virtual trajectory circuit when clearly distinguished from the individual section virtual trajectory circuit) is provided.
This extended virtual track circuit is not actually present on the track, but is based on logical processing that is manifested by the function of the integrated interlocking device 10. For example, the integrated interlocking device 10 has either data or program execution state. It exists in the aspect according to one or both or it.

  The near-station virtual track circuit logic processing means 15 performs state setting for each of the virtual track circuits (extended virtual track circuits) described above. Specifically, if it is detected on the basis of the status information of the departure station's track circuit that the train has advanced from the departure station at one end of the corresponding continuous section (deemed single track section), the corresponding virtual track circuit is displayed. It is recognized that the train has entered, and the state of the corresponding virtual track circuit is set to the train on-line state. The near-station virtual track circuit logic processing means 15 detects that the train has entered the arrival station on the other end side of the target continuous section (deemed single line section) based on the status information of the track circuit of the arrival station. Then, it is recognized that the train has advanced from the corresponding virtual track circuit, and the state of the corresponding virtual track circuit is set to a train non-existing line state.

  Further, based on the introduction of such a virtual track circuit (extended virtual track circuit), the close-to-station block logic processing means 13 closes the block logic when processing the block logic for a continuous section regarded as one section. The arrival points of the competing departure traffic lights on both sides of the target continuous section (deemed single line section) are virtual track circuits, and which departure traffic signal is the virtual track circuit that is the arrival point. By using an exclusive condition as to whether or not to use first (faster in time), the closing logic is processed. For this reason, the inter-station close logic processing means 13 also has a simple and easy-to-understand link table that embodies the logic, and can be easily checked and changed.

  Further, both the adjacent station virtual track circuit logic processing means 14 and the near station virtual track circuit logic processing means 15 recognize the train approach and the train advance according to the virtual track circuit as described above. Strictness is achieved by limiting the process to a series of steps. That is, the train approach to the virtual track circuit shows a signal that the departure signal indicates the progress at the departure station, and a series of track circuits existing in the train traveling direction, in turn, each represents a definite fall that represents the train line. After entering the state, it becomes a confirmed uplift state representing a train non-existing line, indicates a state transition corresponding to train travel, and further, for example, a predetermined time for confirmation of 120 seconds elapses from the final state transition so as to be recognized. It has become. The train advancement from the virtual track circuit shows a signal that the in-field traffic signal indicates the progress at the arrival station, and the first inward track circuit (that is, the first track circuit of the in-field signal device on the target section side at the arrival station) In addition, the state transition corresponding to the train running, which indicates the state where the train is in a definite standing state representing the train non-existing line after being in the definite fall state representing the train existing line, is approved.

  Neighboring station near station switching means 16 performs the virtual track circuit logic processing between adjacent stations as the bearer of the virtual track circuit logic processing and the block logic processing related to the portion where the special automatic block section is continuous in the line area to be processed. A pair of means 14 and adjacent station closing logic processing means 12 (hereinafter also referred to as a normal time means set 12 + 14) and a near station virtual track circuit logic processing means 15 and a near station closing logic processing means 13 (Hereinafter also referred to as abnormal condition means set 13 + 15), and any one of the special automatic block sections in the steady state is adopted as the normal condition means set 12 + 14. When an abnormality occurs at a station in the range, switching is performed such that the abnormality means group 13 + 15 is adopted for the corresponding part. It should be noted that the detection of an abnormality is automatically performed upon receipt of a notification to notify the abnormality or disruption of normal communication, etc., and also requires confirmation by manual input by the operator who examined the abnormality status. It has become.

By this switching, in the normal state / steady state where no abnormality is particularly found, the virtual track circuit logic and the closing logic are set to the normal state means group 12 + 14 for each special automatic closing interval for each special automatic closing interval. It is processed by.
On the other hand, it is an abnormal signal that an abnormality has occurred in the control terminals 6 of the stations A, B, C,..., Field devices such as traffic lights, switchboards, track circuits, etc. (these are collectively referred to as field devices). And when the station to which the abnormal field device belongs is an intermediate station of the “continuation section”, two or more two belonging to the subsequent section are detected. As for the special automatic closing section, the virtual track circuit logic and the closing logic are processed by the abnormal condition means set 13 + 15 as in one section.

  That is, the adjacent station switching means 16 receives an abnormal signal and an input from the operator when an abnormality occurs in the field device provided at the arrival station which is the next station, and determines the arrival point corresponding to the individual section. In order to switch from the virtual track circuit for extension to the extended virtual track circuit, the virtual track circuit logic processing means 14 between the adjacent stations is removed from the charge of the logical process of the corresponding virtual track circuit, and the virtual track circuit logic process between the near stations is newly assigned. Adopting the means 15, and in order to extend the closing section from the departure station to the next station (next station) from the departure station to the next station (near station), next to the responsible logic processing of the corresponding virtual track circuit The inter-station close logic processing means 12 is removed and the close inter-station close logic processing means 13 is adopted as a new charge.

Further, the adjacent station switching means 16 switches from the normal time means set 12 + 14 to the abnormal time means set 13 + 15, so that the actual train line setting target is changed from the individual section virtual track circuit to the extended virtual track circuit. In addition, the following conditions must be satisfied before the station from the departure station to the next station is actually handled as one closed section. The condition confirmation may be performed by a cooperative action between the neighboring station near station switching means 16 and the near-station virtual track circuit logic processing means 15, or by any one of the single actions. You may come to be.
Hereinafter, the conditions will be described in detail according to cases before and after the departure of the train.

  Before the train departs from the departure station, the closing configuration condition (first switching condition) is as follows: (1) reception of a notification notifying the abnormality of the next station and communication with the control terminal 6 being interrupted continuously for a predetermined period. (2) The next station is in a side line state (the upside and downside trains switch so that they can pass on the same track and switch to a predetermined direction. The state of a side line station where there is no turning machine and there is no distribution of the track.The steady state is this side line state, when the course that must change the turning machine in the opposite direction (1) Unlock the lock of the corresponding switch and then configure the course) (3) Virtual track circuit between the departure station and the next station (neighboring station) The virtual orbit circuit between the next station (next station) and the next station (near station) also in the nearest individual section virtual track circuit) There is no train on the (virtual track circuit for individual section ahead), and (4) the virtual traffic track for individual section that is competing in the opposite direction of the next station (close station) The circuit is not used as an arrival point, and (5) Further, it is determined that the abnormality of the next station is certain with respect to the requirements (1) to (4), for example, 30 seconds (transmission time, number of periods until the abnormality is confirmed) (6) The driver has confirmed from the display control panel 3 that he / she has input “abnormal next station” before departure. It is all satisfied. In addition, even if the train is stopped at the intermediate station, switching is possible if it is in a sideline state.

  Also, if the train has already departed from the departure station and is on the virtual track circuit between the departure station and the next station (neighboring station), the closing configuration condition (second switching condition) is (1) next That the next station is surely abnormal, such as receiving notifications that report station abnormalities and communication with the control terminal 6 being interrupted for a predetermined period; (2) that the next station is in a side-line state; and (3) The next station's steady route is configured (the route is locked, the signal route is secured exclusively), and a signal indicating the progress is displayed, and (3) the next station ( That there is no train on the virtual track circuit (the virtual track circuit for the individual section ahead) between the next station and the next station (near station), and (4) the opposite of the next station (near station) The starting traffic signals with competing directions do not use the individual section virtual track circuit as the arrival point, and (5) further ( ), (4) The requirement establishment state has been continued, for example, 30 seconds before the next station abnormality is determined to be reliable, and (6) the driver handles the “next station abnormality” from the display control panel 3. The fact that “has been input” has been confirmed means that the individual section virtual track circuit is fully satisfied before the train advances. In this case as well, even if the train stops at the next station, which is an intermediate station, switching is possible if the train is in a sideline state.

Then, when the above-described blockage configuration condition (switching condition) is satisfied, the target to be closed is switched from the individual section virtual track circuit to the extended virtual track circuit, and the arrival point of the departure signal at the departure station is switched to the extended virtual track circuit, This allows exclusive control (position locking) of competing departure traffic signals in the opposite direction of the station (near station) one after another.
In addition, when the train is on the side line of the next station (intermediate station), the closing configuration condition (third switching condition) is the same as the above-described closing closing configuration condition (second switching condition). Yes, but if the train is on a different track from the next station (intermediate station), it will switch to the sideline and the machine will be switched and locked. I can't. In the latter case, since automatic processing of the integrated interlocking device 10 is not permitted, the traveling of the train or the like has to wait for maintenance personnel to be dispatched to ensure the opening of the route.

  Also, the condition for switching from the abnormal time means group 13 + 15 to the normal time means set 12 + 14 by the adjacent station switching means 16, in other words, the condition for returning the closed section for the extended virtual track circuit to the steady state, specifically Is a condition for switching one extended virtual track circuit and a closed section to two virtual track circuits and a closed section, more specifically, an extended virtual track circuit from the departure station to the next station (near station) from the departure station to the next station Switch to the virtual track circuit for individual sections from (next station) to the virtual track circuit for individual sections from the next station (next station) to the next station (near station) and close from the departure station to the next station (near station) The conditions for switching the section from the departure station to the next station (next station) and the next section (next station) to the next station (near station) are as follows.

  In other words, the failure of the next station has been recovered (specifically, all on-site equipment such as control / display of traffic lights and switchboards, indication of track circuit presence / absence, control terminal operation, communication functions, etc.) The next station is also in the virtual track circuit between the departure station and the next station (neighboring station) (the virtual track circuit for the nearest individual section). There is no train on the virtual track circuit (next virtual track circuit for the individual section) between (next station) and the next station (close station), and the opposite direction of the next station (close station) It was confirmed that the competing departure traffic lights of No. 1 did not use the virtual track circuit for the individual section ahead as the arrival point, and that the driver handled “the next station normal input” from the display control panel 3 When all of the above are satisfied, the closed section for the extended virtual track circuit is designated as a virtual track circuit for individual sections. It can be returned to the steady state of interest. Note that this return condition can also be switched when a train or the like is on the track circuit not related to the steady route at the next station (neighboring station) which is an intermediate station.

Next, a specific example such as an interlocking table for adapting the processing contents of each of the means 11 to 16 to the individual route will be described. Prior to that, an exemplary route to be applied will be described (see FIG. 2).
To explain from the outline (see FIG. 2 (a)), the example route includes station A, section <A6RT>, station B, section <B6RT> and station C in order from the starting point / upward side to the ending point / downward side. Section <C6RT>, D station, section <D6RT>, and E station (not shown) are provided (section <D6RT> is shown only in FIG. 2 (e)). These sections <A6RT>, <B6RT>, <C6RT>, and <D6RT> are all single line sections, and are special automatic block sections without a track circuit.

  The structure of the station A is shown in detail in the station A partial link FIG. 21 (see FIG. 2B). In summary, all of the three branch lines on the upstream side are dead ends, and there are track circuits in those sections. And a pair of traffic lights [(A1LT), downlink departure signal A7R)], [(A2LT), downlink departure signal A6R], [(A3LT), downlink departure signal A8R]. The track section (A22T) is attached to the first section of the descending traffic signal, the track circuit (A21T) is attached to the section on the descending side, and the section <A6RT> is further arranged on the descending side. A21L, A7L, A8L are installed in the vicinity of the boundary between A21T) and the section <A6RT>. In the present embodiment, when the sections and the track circuits are in one-to-one correspondence and there is no possibility of confusion, the same symbol name / symbol is used to identify them.

  The configuration of the B station is shown in detail in the B station partial interlocking diagram 22 (see FIG. 2C), but in summary, the track circuit (B11T) and the section adjacent to the above-described section <A6RT> from the down side A down-traffic signal B1R is attached, and a track circuit (B1RT) and a down departure traffic light B6R are attached to one of the downlink home truck sections bifurcated from the section, and a track circuit (B8LT) is connected to the other up-home track section. ) And an upstream departure signal B3L, a track circuit (B21T) and an upstream signal B8L are added to the downstream section where both sections merge, and the downstream side is a section <B6RT>.

  The configuration of station C is shown in detail in FIG. 23 (see FIG. 2 (d)), but in summary, the track circuit (C11T) and the section adjacent to the section <B6RT> from the down side are shown in FIG. Downstream signal devices C1R and C2R are attached, and a track circuit (C1RT) and a downlink departure signal device C6R are attached to one of the downlink home track sections bifurcated from the section, and a track circuit (C12T) is connected to the other branch line. A track circuit (C2RT), a descending departure signal C7R, and an ascending departure signal C4L are attached to the section of the home track shared with another descending train and ascending train that is re-branched, and the other re-branching line A track circuit (C8LT) and an upstream departure signal C3L are attached to the section of the upstream home track, and the track circuit (C21T) and the upstream are connected to the downstream section where these sections merge. Inner traffic C8L, C9L is attached, further the downstream side is in the interval <C6RT>.

  The structure of the D station is shown in detail in the D station partial interlocking FIG. 24 (see FIG. 2 (e)). In summary, the track circuit (D11T) is arranged in the section adjacent to the section <C6RT> from the down side. A traffic signal D1R in the downlink is attached, a track circuit (D1RT) and a downlink departure signal D6R are attached in one of the downlink home track sections bifurcated from that section, and a track circuit (D8LT) is connected in the other uplink home track section. ) And an upstream departure signal D3L, a track circuit (D21T) and an upstream signal D8L are added to the downstream side where both sections meet, and the downstream side is a section <D6RT>.

  Since there are a plurality of special automatic closing sections on such example routes, virtual track circuits (individual section virtual track circuits) corresponding to each section are defined. Specifically (see FIG. 3 (a)), the train track status of the virtual track circuit <A6RT> corresponding to the section <A6RT> between the adjacent A station and B station is maintained in the data area of the integrated interlocking device 10. Definition data 31 to be stored, definition data 32 for maintaining the train line status of the virtual track circuit <B6RT> corresponding to the section <B6RT> between the adjacent B station to C station, and the section between the adjacent C station to D station Definition data 33 or the like that holds the train track status of the virtual track circuit <C6RT> corresponding to <C6RT> is allocated.

  Any one of the definition data 31 to 33 is used by the inter-station virtual track circuit logic processing means 14 to define a specific processing target and contents thereof. By holding data up to the entry conditions and advance conditions in the down and up directions, which are the conditions, it is possible to adapt to various routes only by changing the data without modifying the virtual track circuit logic processing means 14 between adjacent stations. Versatile. The condition portion will be described in detail by way of an example. “B21T ↑” is set in the second row and third column of the definition data 32 of the virtual track circuit between adjacent stations B to C. The virtual track circuit <B6RT> It is shown that the final determination condition that the down train has entered is a transition from the falling state of the train line of the track circuit (B21T) to the uphill state of the train non-existing line.

  Note that the waiting for a predetermined time for confirmation after that, for example, 120 seconds, is a common condition, so it is not set in the definition data 31, 32,... In this case, the data items can be easily realized by providing them in the definition data 31-33. In addition, flags and traffic signal identification information such as which traffic signals are used exclusively or not by each traffic virtual circuit for each individual section are provided in definition data 43, 47, 53, and 57 to be described later, for example. Thus, exclusive control can be realized easily.

  Further, a virtual track circuit (extended virtual track circuit) corresponding to the continuous section is defined for a continuous section in which two special automatic closed sections are connected across the intermediate station on the same exemplary route. Specifically (see FIG. 3 (b)), the data area of the integrated interlocking device 10 corresponds to the continuation section <A6RT> to <B6RT> between the A station and the C station between the near stations having the B station as an intermediate station. Virtual track circuit corresponding to the definition data 34 for maintaining the train track status of the virtual track circuit <extension A6RT> and the continuation sections <B6RT> to <C6RT> between the B station and the D station between the C station and the intermediate station The definition data 35 and the like of the virtual track circuit between the B station to the D station between the nearby stations that hold the train extension state of <extension B6RT> are allocated.

  These extended virtual track circuit definition data are used by the near-station virtual track circuit logic processing means 15 to define the specific processing object and contents thereof. Similar to the data, in addition to the train line status, data is stored up to the entry conditions and entry conditions in the down direction and the up direction, which are the judgment conditions for the state change, so that the near-station virtual track circuit logic processing means 15 is not modified. By simply changing the data, it is highly versatile and can be adapted to various routes. In addition, flags and traffic signal identification information such as which traffic signals each extended virtual track circuit is used exclusively or not are provided in, for example, definition data 44, 48, 54, and 58 to be described later. Yes.

Comparing both virtual track circuits, the entry condition and advance condition track circuit for the individual section virtual track circuit are those of the local station and the next station (next station), whereas the extended virtual track circuit is the entry condition and advance condition. The track circuit is that of its own station and nearby station (next to the next station, one after another).
In addition, about these sections and virtual track circuits, that is, for individual sections and virtual track circuits for individual sections, also for sections (deemed single line sections) and extended virtual track circuits, sections and track circuits have been described above. Similarly, since the two correspond one-on-one and there is no possibility of confusion, the same symbol name is used to identify the two corresponding to each other.

And the competitive relationship related to the traffic signal shown in the above-mentioned interlocking diagram is shown in the interlocking table for each station A, B,... (See FIGS. 4 and 5), but only the competing traffic signal and virtual track circuit are shown. .
More specifically, in the A station partial link table 41 extracted from the link table of A station (see FIG. 4A), each of the traffic lights A6L, A7L, A8L, A6R, A7R, A8R of the A station The competing A station (own station) traffic lights are identified in the column of the individual interlocking portion 42, and each of the A departure stations A6R, A7R, A8R of the A station and the B station (adjacent station) competing for the virtual track circuit <A6RT>.

The upstream departure signals C3L and C4L of the C station (neighboring station) that are identified in the column of the interblock portion 47 and compete for the virtual departure circuit B6R and the virtual departure circuit <B6RT> of the B station are also in the column of the interblock adjacent portion 47. The upstream departure signal D3L of the D station (near station) competing with the downstream departure signal B6R of the B station and the virtual track circuit <extension B6RT> is identified in the column 48 between the nearby stations.

  Further, in the C station partial linkage table 51 extracted from the C station linkage table (see FIG. 5A), the traffic signals at C station C1R, C2R, C3L, C4L, C8L, C9L, C6R, C7R The traffic signal of C station (own station) competing with each other is specified in the column of the individual interlocking portion 52, and the B station (adjacent station) competing with each of the upstream departure traffic signals C3L and C4L of the C station and the virtual track circuit <B6RT>. The downstream departure signal B6R of the station D is identified in the column of the adjacent station block portion 53, and the upstream departure signal D3L of the station D (neighboring station) competing with each of the downstream departure signals C6R and C7R of the station C with respect to the virtual track circuit <C6RT>. Is also specified in the column of the section 53 between adjacent stations, and the downstream departure signal A of A station (near station) competing with each of the upstream departure traffic signals C3L, C4L of the C station and the virtual track circuit <extension A6RT>. R, A7R, A8R are identified in the column 54 between the close stations, and the E station (near station) that competes with each of the downlink departure traffic signals C6R, C7R of the C station and the virtual track circuit <extension C6RT> (not shown) The departure signal E3L is also specified in the column of the close part 54 between the nearby stations.

  In addition, in the D station partial linkage table 55 extracted from the D station linkage table (see FIG. 5B), the D station competing with each of the traffic signals D1R, D3L, D8L, D6R of the D station (self Station) traffic lights are identified in the column of the individual interlocking portion 56, and the downstream departure traffic signals C6R and C7R of the C station (neighboring station) competing with the upstream departure traffic signal D3L of the D station and the virtual track circuit <C6RT> are closed between the adjacent stations. The upstream departure signal E3L of the E station (neighboring station) that is specified in the column of the portion 57 and competes with the downward departure traffic signal D6R of the D station and the virtual track circuit <D6RT> is also specified in the column of the portion 57 between the adjacent stations.

  Among these interlocking tables 41, 45, 51, and 55, the individual interlocking portions 42, 46, 52, and 56 determine the specific objects and contents of the interlocking logic processed by each station individual interlocking logic processing means 11 based thereon. The adjacent station block portions 43, 47, 53, and 57 are based on which the specific objects and contents of the block logic processed by the block processing unit 12 between adjacent stations are determined. Based on the block portions 44, 48, 54, and 58, specific objects and contents of the block logic processed by the block close logic processing means 13 are determined. The relationship between the adjacent stations and the following sections without a track circuit as described above is based on the logic between the adjacent stations by using a logical virtual track circuit and using it in the link table (link condition). The processing means 12 and the close station logic processing means 13 are both highly versatile and adaptable to various routes just by changing the data without modifying the program, as with the individual station interlocking logic processing means 11. It has become.

  Regarding the integrated interlocking device 10 and the integrated interlocking system of the first embodiment, the usage mode and operation will be described with reference to the drawings. FIG. 6 is a flowchart when the descending train travels from the B station to the C station, and FIG. 7 is a detailed flowchart of a part related to the logical processing (step S70) between the adjacent stations (B station, C station). FIG. 8 is a detailed flowchart of a portion related to the logical processing (step S80) between the nearby stations (B station, D station).

  The integrated interlocking device 10 grasps the current position of the train based on the collected track circuit state information, and also displays the control panel 3 based on the planned route information received from the automatic route control device 2 or by the operator. The interlocking logic is processed in order to safely configure (reserve) the necessary course in accordance with the manual input from, but is shared by each means 11-16. That is, securing (configuration) of the route in each station A, B, C,... Is processed by each station individual interlocking logic processing means 11, and between adjacent stations A station to B station, B station to C station, C station. ~ D station,... Is closed by the inter-neighboring station closing logic processing means 12, and the state transitions of the virtual track circuits <A6RT>, <B6RT>, <C6RT>, <D6RT> referenced at that time are adjacent stations. Inter-virtual track circuit logic processing means 14 processes the close station A to C station, B station to D station,... Closes the near station close logic processing means 13 and refers to the virtual The state transitions of the track circuits <extension A6RT>, <extension B6RT>, <extension C6RT>, and <extension D6RT> are processed by the near-station virtual track circuit logic processing means 15.

  The securement (configuration) of each station A, B, C, and D in the station premises by each station individual linkage logic processing means 11 is among the linkage tables 41, 45, 51, 55 of each station (see FIGS. 4 and 5). It is performed by the processing of the interlocking logic defined by the individual interlocking portions 42, 46, 52, and 56, thereby controlling the operation of the traffic lights and the switches in each station. Since the contents of the interlocking logic processing are determined based on the interlocking table (for example, refer to the signal overview for railway electrical engineers “Interlocking Device” published by Japan Railway Electrical Engineering Association), detailed explanation thereof is omitted, but individual interlocking The portions 42, 46, 52, and 56 correspond to the interlocking table that would be specified for each interlocking device if individual interlocking devices were installed at each station A, B, C, and D. The interlocking logic is centrally processed, and at any station, a traffic light and a turning machine operate so that the train travels safely on the planned route within the station premises.

On the other hand, between the stations of both adjacent stations, the section <A6RT> between station A and station B, the section <B6RT> between station B and station C, and the section <C6RT> between station C and station D, The section <D6RT> between the D station and the E station is also a special automatic closing section of a single line section without a track circuit, and when there is no abnormality in the field device at each station, the virtual track circuit logic processing means 14 between adjacent stations respectively. State information indicating whether the train is present or not is set in the definition data 31, 32, 33,... Of the corresponding virtual track circuit <A6RT>, <B6RT>, <C6RT>,.
For simplicity of explanation, the state information indicating the presence / absence of a train is described only as a definite state such as a train existing state and a train non-present state, and does not refer to an indeterminate state during the transition.

  In addition, referring to the status information of such a virtual track circuit (virtual track circuit for individual section), the station-to-station linkage tables 41, 45, 51, 55 (see FIGS. 4 and 5) are also provided. Based on the block portions 43, 47, 53, 57 between the adjacent stations that have been added in the form according to the above-described individual interlocking portion, the closing logic is the logic processing means 12 between the adjacent stations in a manner according to the individual interlocking portion. Therefore, in any station, a section in the traveling direction is exclusively reserved and the corresponding traffic signal or turning machine operates so that the train can safely travel on the planned route.

  Furthermore, between the stations of both stations that are adjacent to each other, there are also two sections <A6RT> to <B6RT> between A station and C station, and two sections <B6RT> to <C6RT> between B station and D station. The two sections <C6RT> to <D6RT> between station C and station E are also continuous sections where the special automatic closing section is adjacent to the intermediate station. The virtual track circuit logic processing means 15 sets state information indicating whether the train is present or not in the definition data 34, 35,... Of the corresponding virtual track circuit <extension A6RT>, <extension B6RT>,. Is done. For the sake of simplicity, this is not referred to as an indeterminate state during the transition.

  In addition, with reference to such a virtual track circuit (extended virtual track circuit), the inter-station station linkage tables 41, 45, 51, and 55 (see FIGS. 4 and 5) are also described above. Based on the close inter-station block portions 44, 48, 54, and 58 that were added in the form corresponding to the individual inter-linkage portion and the block between adjacent stations, the block is closed in a manner according to the individual link portion and the block between adjacent stations. Since the logic is considered as a single line section by the logic processing means 13 between the stations close to each other, the special automatic block with two sections in the direction of travel is one section so that the train can safely travel on the planned route in any subsequent section. It is reserved exclusively like a section.

  Then, depending on the presence or absence of abnormality, logical processing between adjacent stations by means of normal means 12 + 14 (inter-station block logic processing means 12 and inter-station virtual track circuit logic processing means 14) is performed, or abnormal Since the adjacent station near station switching means 16 switches whether the logic processing between the nearby stations is performed by the time means 13 + 15 (close station close logic processing means 13 and near station virtual track circuit logic processing means 15). The execution status of each means 11 to 16 in the integrated interlocking device 10 is exemplified by a case where the down train travels from the B station to the C station or the D station. The case will be described separately (see FIG. 6).

  The present invention has the greatest feature that the arrival point of the train (arrival station on the train operation) can be flexibly changed. However, when the descending train departs from the B station, it is necessary to first determine the arrival point. Then, when the setting trigger of the descending departure signal B6R is manually input by the automatic route control device 2 or the driver and input from the display control panel 3 (step S60), the on-site devices at the next station, C station, are totaled. Whether it is normal or abnormal (step S61). If normal (step S61 “normal” → S62), the virtual trajectory corresponding to the section <B6RT> between the stations B and C The circuit <B6RT> is selected as a target for the virtual track circuit logic processing and the block logic processing (step S62), and the upstream departure signal C3L or C4L of the C station with which the virtual track circuit <B6RT> competes. If it is already used, it waits until it is not used (Step S63 “Use” → End), and if the virtual track circuit <B6RT> is not used by the competing departure traffic light C3L or C4L, the adjacent station (B station, C station) ) Is processed (step S63 “not used” → S70 → end).

  On the other hand, if there is an abnormality in the C station (step S61 “abnormal” → S65), the virtual track circuit <extension B6RT> corresponding to the continuous section <B6RT> to <C6RT> between the B station and the D station is the virtual track circuit. It is selected as the target of logic processing and block logic processing (step S65), and if the virtual track circuit <extension B6RT> has already been used by the competing D departure traffic signal D3L, wait until it is not used (step S66 "use" ”→ End), even if the virtual track circuit <extension B6RT> is not used by the competing departure signal D3L, if the C station (next station) cannot pass in a sideline state, it waits until it can pass (step S66“ Not used ”→ step 67“ impossible to pass ”→ end), the virtual track circuit <extension B6RT> is not used by the competing departure traffic light D3L, but C If (next station) can pass in a sideline state (step S66 “unused” → S67 “passable” → S68), a virtual track circuit between the departure station and the next station (neighboring station) That there is no train on the virtual track circuit between the next station (neighboring station) and the next station (near station) (virtual track circuit for the individual section ahead) After confirming (step S68 “non-existing line” → S69) and confirming that the operator has entered “C station abnormality” (step S69 → S80), between the nearby stations (B station, D station) The interlocking logic is processed (step S80 → end).

  The logical processing between the adjacent stations (B station, C station) in the normal processing such as the C station described above will be described in detail (see step S70 and FIG. 7 in FIG. 6). With respect to the virtual track circuit <B6RT>, the departure signal B6R and In order to exclusively control the competing traffic signals C3L and C4L, a flag indicating that the departure traffic signal B6R is using the virtual track circuit <B6RT> is set in the virtual track circuit definition data 47 between the adjacent stations B to C. (Step S71), and then the departure signal B6R shows a signal instructing the progress (Step S72). When the train advances the inward first track circuit B21T, at that time, the driving direction between the B station and the C station As a result, the final closing is determined (step S73).

When the departure signal B6R shows a signal instructing the progress (step S72), a flag indicating that the departure signal B6R is using the virtual track circuit <B6RT> is set in the definition data 47, and the signals C3L, C4L However, if the departure signal B6R is restored (cancels the setting and returns to the steady position or steady state), the flag that the departure signal B6R is using is controlled. In such a state, the setting such as can be canceled. On the other hand, once the closing is finally confirmed, the train enters the arrival station C (step S77), or is not covered by the present invention. If it is not handled as “retreat driving” to return to station B, the closure will not be unlocked.
As described above, since the closing of the train is confirmed after the train actually departs, an inconvenient situation in which the closing of the train is determined unnecessarily by the trial setting of the route is avoided.

Then (step S73 → S74), the train advances the final track circuit B21T (in addition, the inward first track circuit and the final track circuit are the same track circuit B21T at the B station), and the track circuit B21T is not present in the train. When the state (definitely up state) is reached and the state continues for 120 seconds (predetermined time for confirmation), it is determined that the train has entered the virtual track circuit <B6RT>, and the state of the virtual track circuit <B6RT> Transition from the standing line state to the train standing line state (step S74).
After that, the train travels through the section <B6RT> and approaches the station C, so that a setting trigger for the traffic signal C1R or C2R (determining whether C1R or C2R is determined by train operation information or the train schedule) is input. It is confirmed that C1R or C2R has displayed a signal instructing the progress (step S75).

  And if a train advances the inward 1st track circuit C11T of C station, it will determine that the train has advanced the virtual track circuit <B6RT> at that time, and will unlock the downward block between B station-C station ( Step S76). Specifically, the state of the virtual track circuit <B6RT> is returned from the train standing state to the train non-tracking state, and the flag indicating that the departure signal B6R is not using the virtual track circuit <B6RT> is set to the B station between adjacent stations. By setting in the definition data 47 of the virtual track circuit of the ~ C station, the downward block between the B station and the C station is unlocked, and the driving direction of this section is confirmed to be closed in both the downward and upward directions It will be in a state that is not. Further, when the train has completely entered the home track C2RT of station C, the on-site signal C2R is restored (returned to a steady position or a steady state) (step S77). In this way, the train can travel safely from B station to C station, and the section <B6RT> that has been exclusively used is released to other traffic lights, so it is possible to set up an upstream departure signal C3L or C4L at C station become.

  Of the above-described processing at the time of C station abnormality, logic processing between nearby stations (B station, D station) will be described in detail (see step S80 and FIG. 8 in FIG. 6). With regard to the virtual track circuit <extension B6RT> In order to exclusively control the competing traffic light D3L, a flag indicating that the departure traffic light B6R is using the virtual track circuit <extension B6RT> is set in the definition data 48 of the virtual track circuit between B station to D station between the nearby stations. (Step S81), and then the departure signal B6R shows a signal instructing the progress (Step S82). When the train advances the inward first track circuit B21T, the driving direction between the B station and the D station is then lowered. The closing is finally confirmed (step S83).

Then, when the train advances to the final track circuit B21T of the B station, the track circuit B21T enters the train non-existing state (definite rise state), and the state continues for 120 seconds (predetermined time for confirmation), the virtual track circuit It is determined that the train has entered <extended B6RT>, and the state of the virtual track circuit <extended B6RT> is changed from the train non-existing line state to the train existing line state (step S84).
After that, the train continued and traveled in the section <B6RT> to <C6RT> and approached D station, so that the setting trigger of the traffic signal D1R in the downfield was input, and the signal instructing the progress of the traffic signal D1R was shown. Is confirmed (step S85).

  And if a train advances the inward 1st track circuit D11T of D station, it will be judged that the train has advanced the virtual track circuit <extension B6RT> at that time, and the downward block between B station-D station will be unlocked. (Step S86). Specifically, the state of the virtual track circuit <extension B6RT> is returned from the train presence state to the train non-existence state, and a flag indicating that the departure signal B6R is not using the virtual track circuit <extension B6RT> It is set in the definition data 48 of the virtual track circuit from the station to the D station, and the downward block between the B station and the D station is unlocked. Not in a state. Further, when the train has completely entered the home track D1RT of the D station, the in-site traffic signal D1R is restored (returned to a steady position or a steady state) (step S87). In this way, the continuation section <B6RT> to <C6RT> are treated as one single-line section so that the train can safely travel from B station to D station, and the continuation section <B6RT> to < Since C6RT> is released to other traffic lights, it is possible to set the upstream departure traffic light D3L at the D station.

  As mentioned above, although the specific example was described based on the example route, when deducted, it can be said that the integrated interlocking device 10 is as follows. That is, not only individual interlocking stations are specified as the application target of the interlocking logic, but adjacent stations of a certain interlocking station are specified in advance. In addition, not only the next station (next station) located right next to the next station, but also a station located further ahead, that is, a nearby station (next station) located next to the next is designated. In addition, in that case, for a single line section that is adjacent to the intermediate station, multiple candidates such as a departure signal in the opposite direction of the next station and a departure signal in the opposite direction of the next station as the opponent of the competing departure signal in the linked table It prescribes, and either one is selected according to the presence or absence of abnormality of the field device at the intermediate station, and exclusive control (stereoscopic locking) is performed between the selected departure signals.

  The departure signal of the arrival station that competes with the departure signal of the departure station is a departure signal in the opposite direction of the next station (neighboring station) when the next station (neighboring station) is normally operating normally. When the on-site device at (next door station) becomes abnormal, after confirming the input of the driver handling the abnormality, the competing departure signal becomes the departure signal in the opposite direction to the station (near station) one after another. In addition, the abnormal next station (intermediate station) has a function of a side line state, and the next station is handled as a side line station. In this way, when the normal section from the departure station to the next arrival station (next station, next station) is normal, but the intermediate station's on-site equipment is abnormal, the next arrival station (one after another) By changing (extending) to (station, near station), it is possible to secure the operation of the line area while degenerating, so apart from the terminal station and main station, Redundancy is no longer essential, and costs can be reduced.

  In addition, the train tracking function necessary for the processing of the interlocking logic is embodied by a standard method in the section where the track circuit is provided. That is, in the state where the route is configured (the state where the route is locked), the operation of the continuous track circuit accompanying the movement of the train (climbing) / the order of the drop, the change interval from the previous change (time By monitoring the interval), it is possible to judge the legitimacy of the change in the operation of the track circuit (upward) / falling, and to enter the unlocked condition or the virtual track circuit only on the final condition that passed this determination. (On-line) conditions / advance (non-existing line) conditions, and when the path is not configured, the dredging or dropping is considered to be illegal fraud or illegal dropping. On the other hand, in a section where no track circuit is provided, such a standard method cannot be used and is troublesome. However, in the integrated interlocking device 10, a virtual track that is a logical track circuit as described above. By introducing the circuit, the closing logic can be processed by the above-mentioned standard method even for the special automatic closing section without the track circuit.

  In addition to the virtual track circuit for individual sections between adjacent stations, the extended virtual track circuit between nearby stations can be used as a virtual track circuit so that the normal station can be used as the next arrival station (next station, next station). ) It is also easy and accurate to extend and change the closed section from the departure station to the next arrival station (next station, near station) when the field device at the intermediate station becomes abnormal. It is possible to do. In addition, the presence of the virtual track circuit (train approach) is determined by the fact that the final track circuit of the departure route of the departure station has continued for a predetermined time for confirmation of 120 seconds. (Train advancement) is determined by the fact that the inward first track circuit of the in-track route at the arrival station is determined and lifted, so it is easy to determine whether the virtual track circuit is on line (entrance) / not on line (advancement) It is something that can be done accurately.

  In addition, with regard to the closing configuration function of the special automatic closing section, the arrival point of each departure signal is set as one of the individual section virtual track circuit and the extended virtual track circuit according to the presence or absence of an abnormality at the intermediate station. By mutually checking which departure traffic signal is used first in the circuit, the competitor's departure traffic signal is exclusively controlled (position locking), and the interlocking station is locked, that is, the operating direction is determined (time) ) Is inadvertent due to the so-called emptying of the departure signal or an improper short circuit of the track circuit due to the departure of the train by a signal instructing the progress of the departure signal. It is to avoid that the obstruction is fixed.

  Furthermore, the condition (time) for the return signal of the departure signal (return to the steady position or steady state) is the train entry condition (timing) regardless of whether the subject to be closed is an individual section virtual track circuit or an extended virtual track circuit. As in (), when the final orbital circuit of the corresponding starting route has been confirmed and continued for a predetermined time for confirmation of 120 seconds. In addition, the train advance condition from the virtual track circuit (virtual track circuit for individual section or extended virtual track circuit) is when the inward first track circuit of the traffic signal at the arrival station is in a finalized state. At that point, the closure is unlocked.

Regarding the integrated interlocking system (integrated interlocking device 10, transmission path 4, and control terminal 6) of the first embodiment, operations in an emergency etc. will be described.
In an emergency such as when a passenger falls from the platform to the track, an emergency stop button installed on the platform or the like is operated. Then, at the station where the control terminal 6 equipped with the emergency stop signal control function is installed, the control terminal 6 controls the traffic light by itself according to the operation of the emergency stop button, so that the traffic light displays the stop signal in a short time. Therefore, safety is ensured promptly regardless of the communication speed of the transmission path 4. In addition, in a station where a control terminal 6 not equipped with an emergency stop signal control function is installed, operation information of an emergency stop button is sent from the control terminal 6 to the integrated interlocking device 10 via the transmission line 4, and accordingly A command to the traffic signal is sent from the integrated interlocking device 10 to the control terminal 6 via the transmission line 4, and since the control terminal 6 controls the traffic signal, the time required for transmission is delayed, but the traffic signal displays a stop signal. Therefore, also in this case, safety is ensured.

  In addition, when a vehicle parked or detained on a platform or a service line runs away and the runaway vehicle enters the track circuit including the tipping machine, the runaway vehicle is detected by the track circuit, and the train track information is controlled. It is sent to the terminal 6. Then, at the station where the control terminal 6 having an emergency lock function is installed, the intrusion of the escape vehicle is detected by the control terminal 6 that has input the track circuit information, and the control terminal 6 itself responds accordingly. Safety is secured promptly because the tipping machine included in the track circuit at the destination of the escape vehicle is locked. In addition, at a station where the control terminal 6 not equipped with the emergency lock function is installed, the track circuit information indicating the invasion of the runaway vehicle is sent from the control terminal 6 to the integrated interlocking device 10 via the transmission path 4. In response to this, a command to switch the locking mechanism is sent from the integrated interlocking device 10 to the control terminal 6 via the transmission line 4, and then the control terminal 6 locks the switching mechanism, so that transmission is started. In this case, safety is ensured even though the time is delayed.
