Description

  The present invention relates to a train control system and the like.

  In an ATC (Automatic Train Control) system, which is a type of train control system, control information such as speed limits is provided for each section (section with track circuit units) behind this preceding train based on the position of the preceding train. The ATC signal including the control information of the section is transmitted to the rail of each section. The on-board device performs traveling control (speed control) based on the ATC signal received from the rail.

  By the way, in the ATC system, two types of stop signals are used. In other words, the absolute stop signal used for the absolute stop section where entry of the train is prohibited, such as the section where the preceding train is located or the section where the switch of the turnout is not guaranteed, and the outer stop section of the absolute stop section It is an allowable stop signal used for an allowable stop section that allows entry but must stop within the section. The absolute stop signal is a non-signal in which the ATC signal is not transmitted, and the allowable stop signal is a signal including the distance from the entry side to the stop position in the section (see, for example, Patent Documents 1 and 2).

Japanese Patent No. 2829588 Japanese Patent No. 4580068

  As described above, the ATC signal is generated and transmitted for each section according to the current section of each train. That is, the on-board device receives a new ATC signal at the timing when the own train enters a new section or when the existing section of the preceding train changes. The on-board device stores the content of the received ATC signal, updates the stored content every time a new ATC signal is received, and performs traveling control based on the latest ATC signal content. The reliability of the ATC signal, which is a digital telegram, can be improved by, for example, matching the signal contents continuously a predetermined number of times or adding an error correction code.

  However, when the track circuit of each section is a non-resonant type non-insulated track circuit, if the preceding train is in the vicinity of the ATC signal driving point, most of the ATC signal flows to the preceding train side. The rear section next to the current section of the train must be no-signal. That is, in the case of a non-resonant non-insulated track circuit, the allowable stop signal must be no signal. In that case, in the conventional method, the no-signal section becomes an absolute stop section, so the next rear section of the current section of the train is prohibited from entering the subsequent train, and there is a limit in shortening the train interval, It was difficult to shorten the gap.

  In the case of a track circuit including a non-resonant non-insulated track circuit, an ATC signal transmitted to a certain section may flow into another section. That is, the ATC signal received by the on-board device may not be the ATC signal transmitted to the existing section of the own train but the ATC signal of the neighboring section including the upper and lower lines due to guidance or wraparound. In this case, the received ATC signal is a regular ATC signal, but is not an ATC signal corresponding to the current train section of the own train, so it can be said to be a pseudo signal for the on-board device. The on-board device cannot distinguish between an ATC signal that should be originally received and transmitted in the current line section, and a pseudo signal. For this reason, for example, in a non-resonant non-insulated track circuit, by receiving a pseudo signal in an allowable stop section that is a no-signal section, the pseudo signal There is a possibility that a very dangerous situation may occur such that the reception control signal is recognized as not being a permissible stop section and travel control not corresponding to the permissible stop section is adopted.

  According to the first aspect of the invention, the on-board device stores and updates the in-zone section information and the next section information based on the traveling control information received from the rail. And when traveling control information is newly received, when the transmission destination section ID in the newly received traveling control information is different from the transmission destination section ID in the stored line section information, it is newly received. It is determined whether or not the transmission destination section ID in the traveling control information matches the inner section ID in the stored next section information. If they match, it means that the own train has entered a new section, and based on the newly received travel control information, the stored section information and next section information that has been stored is updated, Then, the speed check pattern is created using the updated in-zone section information and the next section information, and the traveling control is performed.

  On the other hand, if they do not match, the newly received travel control information is discarded, and travel control based on the speed verification pattern created previously is performed. That is, the newly received signal related to the travel control information is determined to be a pseudo signal, and the information is discarded. Thereby, it is possible to prevent the traveling control based on the pseudo signal from being performed.

The on-board device further includes an in-section travel distance calculation unit that calculates an in-section travel distance indicating a distance traveled in the existing section of the own train,
When the transmission section is an inward section of the preceding train, the transmission means sets the transmission destination section as an allowable stop section by making no signal by not transmitting the travel control information. When the inner section of the transmission destination section is the outer section of the preceding section of the previous train, the inner section of the first section is the allowable stop section as information on the inner section of the first section. Identification information indicating that it is present, and entry allowable distance information indicating a distance allowing entry into the inner section of the first section is further included in the travel control information, and transmitted.
The control means includes
If the next section is determined to be the allowable stop section based on the next section information stored in the storage means, the own train is stopped by the allowable entry distance indicated by the allowable entry distance information of the next section information. Create the speed check pattern as
A train control system may be configured.

  According to this second invention, the ground device further identifies whether or not one inner section of the transmission destination section is an allowable stop section that is one outer section of the existing section of the preceding train. The information and the permissible distance information indicating the distance permissible for entering the inner section are included in the travel control information and transmitted to the rail of the transmission destination section. Then, when the next section is an allowable stop section, the on-board device creates a speed check pattern so that the own train is stopped by the allowable entry distance indicated by the allowable entry distance information. Therefore, the allowable stop section which is a no-signal section is the next section, and when entering the next section, the own train is controlled to be stopped by the allowable entry distance. Therefore, even if it is a no-signal section, entry is allowed up to the allowable entry distance, so that it is possible to shorten the train interval compared to the conventional case.

Moreover, as 3rd invention, it is the train control system of 2nd invention,
The control means includes
When the travel distance in the section exceeds the section length indicated by the standing section information stored in the storage means, the standing section information is determined based on the next section information stored in the storage section. By updating and deleting the next section information, the travel control information of the same destination section ID as the section ID in the updated existing section information is created until the reception means newly receives the travel control information. Running control based on the speed check pattern
A train control system may be configured.

  According to the third aspect of the present invention, the on-board device is used when the in-section travel distance that is the distance traveled in the current section of the own train exceeds the section length indicated by the stored current section information. Is updated to the next section based on the stored next section information and deletes the next section information, so that the same destination ID as the section ID in the updated existing section information is assumed. Until the traveling control information is newly received, traveling control based on the speed verification pattern that has been created can be performed.

  Therefore, when the allowable stop section, which is a no-signal section, is the next section, and the vehicle enters the next section, traveling control information of the same destination section ID as the section ID related to the entered section is newly received. Until then, the traveling control based on the speed check pattern that has been created previously is performed. That is, it will be controlled to stop the own train by the allowable entry distance, and when travel control information of a transmission destination section ID different from the section ID related to the section that has entered is newly received, the signal is Since it is a pseudo signal, the traveling control based on the speed check pattern that has been created before is continued. Therefore, it is possible to prevent the travel control based on the pseudo signal from being performed even in the allowable stop section that is a no-signal section.

[System configuration]
FIG. 1 is a configuration diagram of a train control system 1 in the present embodiment. The train control system 1 is a digital ATC system, and includes a ground device 10 and an on-board device 50 mounted on a train 40 traveling on a track R as shown in FIG.

  On the track R, a section T serving as a unit of travel control of the train 40 in which the rail is divided along the traveling direction of the train 40 is defined. This section T is determined in units of track circuits installed along the track R. The track circuit in each section T is a non-resonant non-insulated track circuit that does not use track resonance at the circuit boundary and does not use rail resonance.

  A section ID is assigned to each section T, but the number of prepared section IDs is smaller than the total number of sections T defined for the trajectory R. That is, since the installed track circuit is a non-resonant non-insulated track circuit, the section IDs of the sections T within a predetermined distance within which the ATC signal transmitted to the rail is assumed to be sufficiently attenuated are not the same. A section ID is assigned to each section T. For example, the section ID is assigned to each section T so that the section IDs prepared along the traveling direction are repeated in a predetermined order.

  Further, the section where the last vehicle of the preceding train 40a is present (section 14T in FIG. 1) is an absolute stop section where there is no signal, and a section (outward) one section behind (outward) this absolute stop section. , Section 15T) is an allowable stop section. The absolute stop section is a section in which entry of the following train 40b is prohibited, and when entering, an emergency brake is applied and the emergency stop must be immediately stopped. The permissible stop section is a section that allows the following train 40b to enter, but must stop within the section. In the present embodiment, since the track circuit is a non-resonant non-insulated track circuit, the allowable stop section is also a section with no signal.

  The ground device 10 includes a plurality of ATC transmitters 20 and a ground control device 30. The ATC transmitter 20 is connected to the boundary on the advancing side of each section, and outputs the ATC signal generated by the ground control device 30 to the rail of the connected section. This connection point is also referred to as an ATC signal input point.

The ground control device 30 includes a standing line detection unit 310 and a transmission control unit 320. The standing line detection unit 310 detects the position of each train on the track R in units of track circuits (that is, sections). The transmission control unit 320 is on the track R based on the train track information detected by the track detection unit 310 or the route information (including branching direction information) obtained from the interlock device (not shown). The travel control information 60 for each train 40 is generated, included in the ATC signal (telegram), and repeatedly transmitted to the corresponding rail in the existing section via the ATC transmitter 20.

  The on-board device 50 performs traveling control of the own train based on the traveling control information 60 received from the rail. Specifically, a speed verification pattern based on the received travel control information 60 is created, and travel control (speed control) according to the speed verification pattern is performed.

  FIG. 2 is a diagram for explaining speed control based on the traveling control information 60. In FIG. 2, the speed check pattern of the following train 40b is shown with the right direction being the traveling direction of the train. As shown in FIG. 2, the current section 14T of the preceding train 40a is an absolute stop section, and the latest rear section 15T is an allowable stop section. In each section, the speed limit is determined according to the position of the preceding train 40a (the existing section) and the speed check pattern of the subsequent train 40b is set so as to keep the speed limit determined in each section. Is done.

  By the way, since the allowable stop section must be stopped within the section, the safety margin distance L2 is estimated from the section length L in consideration of the measurement error of the travel distance in the on-board device 50, the brake operation delay, and the like. Subsequent train 40b creates a speed check pattern so that the allowable entry distance L1 is determined, and the vehicle is stopped (speed is zero) from the entry side of the allowable stop section to the point where the entry is allowed by the entry allowable distance L1. The safety margin distance L2 may be, for example, a fixed distance (for example, 10 m), or a fixed ratio (for example, 5%) with respect to the section length of the section. In the present embodiment, the allowable entry distance L1 is set by the ground control device 30 and included in the travel control information 60 and transmitted to the rail.

  FIG. 3 is a diagram illustrating an example of a data configuration of the traveling control information 60. As illustrated in FIG. 3, the travel control information 60 includes transmission destination section information 61 related to a transmission destination section that is a section in which the information (ATC signal) is transmitted, and an inner section related to one inner section of the transmission destination section. Information 62 is included. Hereinafter, the ATC signal will be described as the traveling control information 60. The traveling control information 60 includes at least a section ID of a transmission destination section, speed information of the transmission destination section, a section length of one section inner section, a section ID of one section inner section, and speed information of one section inner section. Yes. In the present embodiment, the transmission destination section information 61 includes a section ID, a section length, and a start speed Vs and a terminal speed Vo that are speed information. The inner section information 62 includes a section ID, a section length, a start speed Vs and a terminal speed Vo that are speed information, and an allowable stop section flag indicating whether or not the inner section is an allowable stop section. Information indicating the allowable entry distance L1 in the case of an allowable stop section. Here, the starting speed Vs is a speed limit when entering the section, and is a speed limit determined for the section. The terminal speed Vo is a speed limit at the time of advance from the section, and is a speed limit of the inner section. For the allowable stop section, the terminal speed Vo is 0 (zero).

  When the transmission destination section is an allowable stop section, the transmission destination section is a no-signal section, and therefore the transmission destination section information 61 does not include the allowable stop section flag and the allowable approach distance L1.

  By the way, by using a non-resonance type non-insulated track circuit as a track circuit, the ATC signal (running control information 60) transmitted in a certain section is guided to a parallel vertical line or sneak into a neighboring section, There is a possibility of being transmitted to other sections. That is, the on-board device 50 may receive an ATC signal transmitted to another section instead of the section where the own train is located.

  Therefore, in the present embodiment, the on-board device 50 determines whether the received ATC signal is a pseudo signal that is an ATC signal of another section, based on the section ID included in the received ATC signal (travel control information 60). Determine.

  FIG. 4 is a diagram for explaining determination of a pseudo signal based on the section ID. A section is indicated by a number and a character string “T”, and the parenthesis below the section is the section ID of the section. As shown in FIG. 4 (1), the on-board device 50 of the train 40c receives the traveling control information 60a that is an ATC signal transmitted to the section 16T where the own train 40c is present, and this traveling control information. “Inward section ID = ID−B” included in 60a is stored.

  Next, as shown in FIG. 4 (2), when the train 40c enters the next section 15T, the traveling control information 60b transmitted in the section 15T is received. The on-board device 50 determines a match between the transmission destination section ID included in the received travel control information 60b and the stored inner section ID. In this case, the stored inner section ID and the received transmission section ID are both “ID-B” and match. In other words, the on-board device 50 determines that the received travel control information 60b is not a pseudo signal, and stores the stored inner section ID “inner section ID = ID included in the newly received travel control information 60b. -C "is updated and stored, and the speed check pattern is updated based on the received travel control information 60b.

  FIG. 4 (3) is an example in which, following FIG. 4 (2), the train 40c enters one section outside the existing section of the preceding train 40d (that is, the allowable stop section) and receives a pseudo signal. It is. At this time, since the entered section 14T is an allowable stop section, the ATC signal in this section 14T should be no signal. However, FIG. 4 (3) shows a case where the ATC signal (running control information 60d) transmitted to the parallel reverse rail propagates to the section 14T by guidance, wraparound, or the like. In this case, the on-board device 50 receives the traveling control information 60d transmitted in the section 21T. “Inward section ID = ID-C” stored in the on-board device 50 and “destination section ID = ID-D” included in the received travel control information 60c do not match. That is, the on-board device 50 determines that the received traveling control information 60d is a pseudo signal and discards it as invalid.

  Since the section 14T is an allowable stop section, the speed check pattern created during the travel of the section 15T immediately before the section 14T is a pattern for stopping before the allowable entry distance L1 of the section 14T. Therefore, the on-board device 50 of the train 40c performs traveling control based on the speed check pattern that has been created before, and stops the own train (train 40c) by the allowable entry distance L1 of the section 14T. Further, although the rear section (outer section) 14T next to the existing section of the train 40d that is the preceding train is a no-signal section, it can be said that the train 40c that is the subsequent train can enter the allowable entry distance L1. . Therefore, the train interval can be shortened as compared with the prior art, and the operation interval can be shortened.

  4 (3) shows an example in which the pseudo signal is received in the allowable stop section, but the on-board device 50 is also simulated according to the logic described above even when the pseudo signal is received in the section that is not the stop section. The signal can be determined and discarded as invalid.

[Function configuration]
FIG. 5 is a functional configuration diagram of the on-board device 50. According to FIG. 5, the on-board device 50 is a kind of computer device that includes a processing unit 100 and a storage unit 200.

  The processing unit 100 is realized by an arithmetic device such as a CPU, for example, and performs overall control of the on-board device based on programs, data, and the like stored in the storage unit. In addition, the processing unit 100 includes a position speed calculation unit 110 and a travel control unit 120, and controls the travel of the own train 40 based on the ATC signal received by the power receiver 41 from the rail.

  The position speed calculation unit 110 calculates the current travel position (travel distance) and travel speed of the own train 40 based on the measured value of the rotational speed of the speed generator 42 attached to the axle. In addition, the position / velocity calculation unit 110 includes an intra-section travel distance calculation unit 112, and resets the travel distance of the own train 40 every time the section entry determination unit 130 determines that a new section has been entered. Then, the in-section travel distance that is the distance traveled in the current section is calculated.

  The travel control unit 120 includes a speed verification pattern creation unit 121, a brake control unit 122, a section entry determination unit 130, a section ID collation unit 140, and a storage content update unit 150, and the received travel control information 60 The in-track section information 220 and the next section information 230 stored in the storage unit 200 are updated based on the information, and the traveling control of the own train is performed based on the in-track section information 220 and the next section information 230.

  The speed check pattern creation unit 121 creates a speed check pattern based on the existing section information 220 and the next section information 230. Specifically, it is updated when the in-zone section information 220 and the next section information 230 are updated based on the newly received traveling control information 60 (in the case of a first cause and a second cause described later). The speed check pattern according to the various information of the existing track section information 220 and the next section information 230 is created / updated.

  The brake control unit 122 performs brake control according to the speed verification pattern created by the speed verification pattern creation unit 121. Specifically, the current travel speed is compared with the current travel speed (limit speed) determined by the speed verification pattern. If the travel speed exceeds the verification speed, the service brake 43 is operated. Decelerate to check speed. In addition, when the current travel section is an allowable stop section and the travel distance after entering the section (intra-section travel distance) exceeds the section length of the section, or the travel section is an allowable stop section If there is no signal in which no ATC signal is received despite the absence, the emergency brake 44 is operated to stop the own train in an emergency. Whether the current travel section (current section) or the next section that is an inner section of the current section is an allowable stop section can be determined by the allowable stop section flag of the existing section information 220 and the next section information 230 (see FIG. 6). .

  The section approach determination unit 130 changes the transmission destination section ID included in the received travel control information 60 or the section travel distance calculated by the section travel distance calculation section 112 exceeds the section length of the existing section. It is determined whether or not the own train has entered a new section. Specifically, the transmission destination section ID included in the received travel control information 60 is changed, and the transmission destination section ID included in the newly received travel control information 60 is the section ID (inward) of the next section information 230. If it matches the section ID), it is determined that the own train has entered a new section (corresponding to a first cause described later). Even if the new travel control information 60 is not received, if the intra-section travel distance exceeds the section length of the existing line section information 220, it is determined that the own train has entered a new section (described later). Corresponding to the third reason).

  The section ID collating unit 140 collates the transmission destination section ID included in the received travel control information 60 with the section ID (the existing section ID) of the existing section information 220 and the section ID (the inner section ID) of the next section information 230. Then, it is determined whether or not they match.

  The stored content update unit 150 updates the existing section information 220 and the next section information 230 stored in the storage unit 200. There are three reasons for updating. The first cause and the second cause are common to the fact that the new traveling control information 60 has been received. More specifically, the first cause is when it is determined that the transmission destination section ID of the newly received travel control information 60 matches the section ID (inner section ID) of the next section information 230. . In this case, the section entry determination unit 130 determines that a new section has been entered. The storage content update unit 150 updates the standing line section information 220 with the next section information 230, so that the section length, the start speed, the terminal speed, the allowable stop section flag, and the allowable approach distance of the next section information 230 are displayed. Can be copied to. In addition, the storage content update unit 150 updates the standing section information 220 and the next section information 230 to the latest information by updating the standing section information 220 and the next section information 230 with the newly received travel control information 60. be able to. As described above, in the case of the first cause, the speed check pattern creating unit 121 creates and updates the speed check pattern.

  The second cause is when it is determined that the transmission destination section ID of the newly received travel control information 60 matches the section ID (present section ID) of the existing line section information 220, and the travel control information 60 has changed. It is. This is a case where the traveling control information 60 has changed due to a change in the position of the preceding train, although the existing section of the own train does not change. In this case, the stored content update unit 150 updates the standing section information 220 and the next section information 230 to the latest information by updating the standing section information 220 and the next section information 230 with the newly received travel control information 60. To do. As described above, in the case of the second cause, the speed check pattern creating unit 121 creates and updates the speed check pattern.

  The third cause is when the intra-section travel distance calculated by the intra-section travel distance calculation unit 112 exceeds the section length of the existing line section information 220. Also in this case, it is determined by the section entry determination unit 130 that a new section has been entered. The storage content update unit 150 updates the standing line section information 220 with the next section information 230, so that the section length, the start speed, the terminal speed, the allowable stop section flag, and the allowable approach distance of the next section information 230 are displayed. Can be copied to. In addition, although the vehicle has entered a new section but has not received the new travel control information 60, the stored content update unit 150 deletes or resets the next section information 230. Even if new travel control information 60 is not received when entering a new section, speed control is performed with the speed check pattern that was previously created while traveling in the previous section, which is problematic. There is nothing. This is because when the traveling control information 60 is newly received, the second cause is generated, and the speed verification pattern creation unit 121 creates and updates the speed verification pattern. Note that when the newly entered section is an allowable stop section, speed control is performed using the speed check pattern created during traveling in the previous section, so there is no problem.

  The storage unit 200 is realized by a storage device such as a ROM, a RAM, and a hard disk. The calculation result used by the processing unit 100 is temporarily stored as an area. In the present embodiment, the on-board control program 210, on-track section information 220, and next section information 230 are stored.

  FIG. 6 shows an example of the configuration of the in-zone section information 220 and the next section information 230. The standing section information 220 is information related to the standing section of the own train 40, and the next section information 230 is information related to the next section (inward section). Unlike the transmission destination section information 61 and the inward section information 62 shown in FIG. 3, the standing section information 220 and the next section information 230 are all section ID, section length, start speed Vs, end speed Vo, and allowable stop section. It includes information indicating a flag and an allowable entry distance L1. This is because the contents of the next section information 230 may be copied and updated to the on-line section information 220 by the stored content update unit 150.

[Process flow]
(A) Ground device 10
FIG. 7 is a flowchart for explaining ground control processing in the ground device 10. This process is realized by the transmission control unit 320 executing the ground transmission control program 321.

  According to FIG. 7, the transmission control unit 320 monitors the on-line section of each train detected by the on-line detection unit 310, and the transmission control information (ATC signal) is transmitted according to the change of the on-line section of the train. Control start / end. That is, if the train enters a new section (step A1: YES), the existing section of the nearest train ahead of the train is determined (step A3), and one section rear section of the determined section is set as an allowable stop section. (Step A5). And the traveling control information 60 with respect to the approach area of the said train is produced | generated, and transmission of the travel control information 60 (ATC signal) to the said approach area is started (step A7).

  If the train has advanced into the section (step A9: YES), transmission of the travel control information 60 (ATC signal) to the advanced section is terminated (step A11). Next, one section rear section (that is, advancing section) of the current section of the train is set as an allowable stop section (step A13). Then, the current section of the nearest train behind the train is determined (step A15), travel control information 60 for the determined section is generated, and transmission of travel control information (ATC signal) to the section is started (step A17). ). Then, it returns to step A1 and repeats the same process.

(B) On-board device 50
FIG. 8 is a flowchart for explaining the flow of the on-board control process in the on-board device 50. This process is realized by the processing unit 100 executing the on-board control program 210.

  According to FIG. 8, when the processing unit 100 receives new travel control information 60 (step B1: YES), whether or not the transmission destination section ID included in the received new travel control information 60 has changed. Is compared with the section ID (present section ID) of the stored section information 220 stored, and if it is determined that it has changed (step B3: YES), the section of the stored next section information 230 is determined. A match between the ID (inner section ID) and the newly received destination section ID is determined (step B5). If both section IDs match (step B6: YES), it is determined that the vehicle has entered a new section (step B7). Then, the intra-section travel distance calculated by the intra-section travel distance calculation unit 112 is reset (step B8). In addition, the standing section information 220 is updated with the next section information 230 (step B9), and the standing section information 220 and the next section information 230 are updated based on the received travel control information 60 (step B10). That is, the current section information 220 is updated based on the next section information 230 and the newly received travel control information 60, and the next section information 230 is updated based on the newly received travel control information 60. Then, the speed check pattern creation unit 121 creates and updates a speed check pattern based on the updated in-zone section information 220 and the next section information 230 (step B11). The flow of processing up to this step B11 corresponds to the case where the first cause described above occurs.

  If it is determined in step B6 that the two section IDs do not match (step B6: NO), the newly received travel control information 60 in step B1 can be determined to be a pseudo signal, and the process proceeds to step B21. To do.

  In step B3, the transmission destination section ID included in the received new travel control information 60 has not changed, that is, the transmission destination section that is the same as the section ID (the existing section ID) of the stored section information 220. When it is determined that the ID traveling control information 60 has been received (step B3: NO), it is determined whether the content of the received new traveling control information 60 has changed (step B13).

  When the content of the received new travel control information 60 has changed (step B13: YES), the stored content update unit 150 updates the existing section information 220 and the next section information 230 based on the received travel control information 60. (Step B15). Then, the speed check pattern creation unit 121 creates and updates a speed check pattern based on the updated in-zone section information 220 and next section information 230 (step B17). The flow of processing up to this step B17 corresponds to the case where the second cause described above occurs.

  In addition, when the content of the received new traveling control information 60 has not changed (step B13: NO), steps B15 to B17 are skipped, but step B13 is omitted and the stored track line is stored. If it is determined that the traveling control information 60 having the same transmission destination section ID as the section ID (present section section ID) of the section information 220 is received (step B3: NO), the steps B15 to B17 may be executed without fail. Good.

  In step B1, when no new travel control information 60 is received (step B1: NO), or when it is determined that the newly received travel control information 60 is a pseudo signal (step B6: NO). If the intra-section travel distance calculated by the intra-section travel distance calculation unit 112 exceeds the section length of the existing line section information 220 (step B21: YES), it is determined that the vehicle has entered a new section (step S21). B23). Then, the in-section travel distance calculated by the in-section travel distance calculation unit 112 is reset (step B25), the in-zone section information 220 is updated with the next section information 230 (step B27), and the next section information 230 is deleted. (Step B29). The flow of processing up to this step B29 corresponds to the case where the third cause described above occurs.

  When it is determined NO in Steps B13 and B21, or after the processing of Steps B11, B17, and B29, it is determined whether or not to end this process due to arrival of the arrival station, and so on (Step B31). : NO), the process returns to step B1 and the same process is repeated. If completed (step B31: YES), the present process is terminated.

[Function and effect]
As described above, in the train control system 1 of the present embodiment, the on-board device 50 stores and updates the in-zone section information 220 and the next section information 230 based on the traveling control information 60 received from the rail. If the newly received destination section ID in the travel control information 60 is different from the section ID in the existing section information 220, does the destination section ID match the section ID in the next section information 230? Determine whether or not. If they match, it means that the own train has entered a new section, which means that the first cause has occurred. Therefore, the stored section information 220 is updated based on the stored next section information 230 and the newly received travel control information 60, and the next section based on the newly received travel control information 60. The information 230 is updated, and further, a speed check pattern is created using the updated in-zone section information 220 and the next section information 230 to perform traveling control.

  On the other hand, if the transmission destination section ID in the newly received travel control information 60 and the section ID in the next section information 230 do not match, the newly received travel control information 60 is discarded and created previously. Travel control is performed based on the speed check pattern. That is, the newly received reception signal related to the traveling control information 60 is determined to be a pseudo signal, and the information is discarded. Thereby, it is possible to prevent the traveling control based on the pseudo signal from being performed.

  The ground device 10 also has identification information indicating whether or not one inner section of the transmission destination section is an allowable stop section, and an allowable entry distance indicating a distance allowing entry into the one inner section. The information is included in the traveling control information 60 and transmitted to the rail in the transmission destination section. The on-board device 50 transmits information transmitted from the rail when the transmission destination section ID in the new traveling control information 60 received from the rail and the section ID in the stored track section information 220 are the same. Is updated to the new information, and the existing section information 220 and the next section information 230 are updated based on the newly received traveling control information 60, and the updated speed using the existing section information 220 and the next section information 230 is updated. Create a check pattern to control the run. This is processing corresponding to the second cause. When the next section is an allowable stop section, a speed check pattern is created so that the own train is stopped by the allowable entry distance indicated by the allowable entry distance information.

  The on-board device 50 updates the standing section information 220 based on the next section information 230, assuming that the next section is entered when the traveling distance in the section exceeds the section length in the standing section information 220. By deleting the next section information 230, it is based on the speed verification pattern that has been created before until the travel control information 60 of the same destination section ID as the section ID in the updated in-zone section information 220 is received. Run control. This is a process corresponding to the third cause.

  Therefore, when the allowable stop section which is a no-signal section is the next section, and the vehicle enters the next section, the travel control information 60 having the same transmission destination section ID as the section ID related to the entered section is newly received. (Until the second cause occurs), the traveling control based on the speed verification pattern that has been created previously is performed. That is, it is controlled so that the own train is stopped by the allowable entry distance. When the travel control information 60 of the transmission destination section ID different from the section ID related to the section that has entered is newly received, the signal is a pseudo signal, and thus the travel control based on the speed verification pattern that has been created previously. Will be continued. Therefore, it is possible to prevent the travel control based on the pseudo signal from being performed even in the allowable stop section that is a no-signal section.

  It should be noted that embodiments to which the present invention can be applied are not limited to the above-described embodiments, and can be appropriately changed without departing from the spirit of the present invention.
