The present invention operates as follows.
Each point marker (110) distributedly arranged along the rail transmits point information indicating a point where the own device is arranged to a train passing through the vicinity. The position detection means (250, 240, 261) of the on-board device (200) receives the point information from the point marker (110) to detect the current position of the own train, and the on-board transmission means (230, 262) The position information of the own train is transmitted to the ground device (100).
[0014]
The ground receiving means (120, 130) of the ground device (100) receives the position information sent from the onboard device (200) of each train, and the ground transmitting means (120, 140) receives the received position information. Based on the above, at least the position information of the train preceding the train is transmitted to each train.
[0015]
The on-vehicle reception means (230, 262) receives the position information of the preceding train sent from the ground transmission means (120, 140), and the train control means (210) of the on-board device (200) receives the ground transmission. The speed of the own train is controlled based on the position information of the preceding train and the position information of the own train received from the means (120, 140).
[0016]
Thus, while recognizing the position of the own train in each train based on the point information from the point marker (110) and transmitting it to the ground device (100), the position information of the preceding train via the ground device (100). Therefore, the distance from the preceding train can be grasped according to the arrangement interval of the point markers (110). Therefore, by finely arranging the point markers (110), the distance from the preceding train can be grasped in detail, and the operation interval can be shortened with less capital investment compared to the case where the track circuit is subdivided.
[0017]

[0018]
In this case, the on-board device (200) communicates with the ground receiving device and the ground transmitting device in the communication section (180) where the train on which the device is mounted is located. Also, the terrestrial transmission device is in charge of its own device based on the positional information received by the terrestrial receiving device in the communication section (180) handled by the own device and the positional information received by the terrestrial receiving device in the preceding communication section (180). At least the position information of the train preceding the train is transmitted toward each train in the communication section (180).
[0019]
As a result, even if the communication section (180) is divided into a plurality of sections, it is possible to grasp the position information of the train existing in the preceding communication section (180), and to appropriately send the position information of the preceding train to each train. it can. Since the communication section (180) is not related to the closed section, the length of one communication section (180) can be extended to the maximum communicable distance.

  Also,On-board device (200)IsBased on the point information from the point marker (110) and the travel distance detected by the travel distance detection means (263), the current position of the own train is detected.SoThe position of the train can be grasped in more detail. Moreover, the arrangement | positioning space | interval of a point marker (110) can be lengthened.
[0021]
When there is an abnormality in detection of the travel distance, the train control means (210) performs speed control based on a fixed block section set based on the point marker (110), and the detection of the travel distance is normal. First, speed control is performed based on the distance from the preceding train. Thereby, even when there is an abnormality in the measurement of the travel distance, the speed of the train can be controlled by the fixed blockage based on the point marker (110). Further, when the travel distance measurement is normal, fine speed control according to the distance to the preceding train can be performed.
[0022]
The on-board device (200) further includes an on-board database (220) that stores various information related to the speed control of the train, and the train control means (210) includes the position information of the preceding train and the position information of the own train. And the speed of the own train is controlled based on the information stored in the on-board database (220). For example, regarding the route, information such as station, gradient, curve, branch, point marker arrangement information, vehicle performance, and the like are registered, and the train speed is controlled based on the distance from the preceding train and these data. As described above, since the train speed control is performed based on the various information accumulated in the on-board database (220) and the distance between the preceding trains, it is possible to perform more accurate control in accordance with the course condition and the like.
[0023]
In detecting the train position abnormality based on at least one of the detection order of the point markers (110), the travel distance between the point markers (110), and the travel time between the point markers (110), It is possible to improve safety by accurately detecting an apparatus abnormality. Furthermore, in both the on-board device (200) and the ground device (100) that checks for the presence or absence of an abnormality relating to the speed control of the train, the abnormality is double checked, so that safety is further improved. Can do.

[0043]
Next, the operation of the train control device 10 will be described based on the flowcharts shown in FIGS. 3 and 4. The logic unit 140 of the ground device 100 acquires the route information of the train from the operation management device 150 managed by the train schedule (step S301), and transmits it to the communication section 180 in charge through the vehicle information transmitter / receiver 120. The on-board device 200 receives the route information addressed to the own train sent through the communication section 180 (step S401), and edits the route data based on the route information (step S402). Thereafter, the on-board device 200 performs departure control (step S403), and the ground device 100 confirms the departure of the train 5 (step S303).
[0044]
The ground device 100 transmits the preceding train information to the communication section 180 at all times or at regular time intervals, and the on-board device 200 receives the preceding train information destined for the own train sent through the transmission path of the communication section 180. Process. The on-board device 200 transmits the own train information from the second antenna 262 toward the ground device 100 at all times or at regular time intervals, and the ground device 100 transmits the on-board device via the transmission path of the communication section 180. The own train information from 200 is received. As a result, information is exchanged between the vehicle and the ground (steps S304 and S404).
[0045]
More specifically, the ground device 100 creates preceding train information addressed to each train based on the own train information received from each train. That is, the logic unit 140 in charge of the predetermined communication section 180 receives the own train information received from the train traveling in the communication section 180 in charge and the own train information (forward communication from the train traveling in the front communication section 180). And forward train information related to each preceding train is transmitted to each train traveling in the communication section 180 in charge of the own device. Moreover, the on-board device 200 of each train 5 performs each process shown in FIG. 2 and outputs the own train information having the contents shown in FIG.
[0046]
The logic unit 140 of the ground device 100 checks normality / abnormality of the transmission state in the communication section 180 in charge based on the reception status of the loop verification receiver 130, and when the transmission state is not normal (step S305; N) Then, train stop control for forcibly stopping the train is performed (step S315). When the transmission state is normal (step S305; Y), the last point marker information and train position information passed by each train are input from the own train information sent from each train (steps S306 and S307).
[0047]
Further, it is checked whether or not the own train information sent from each train is normal (step S308). If there is an abnormality (step S308; N), train stop control is performed (step S315). If the above inspection is normal (step S308; Y), whether or not each train passes the point marker in a normal order based on the information on the last passage point marker of the own train sent from each train. The point marker sequence is checked (step S309). If this is abnormal (step S309; N), train stop control is performed (step S315).
[0048]
If the above inspection is normal (step S309; Y), for each train, it is checked whether or not the running time between the point markers is normal (step S310). If it is abnormal (step S310; N). Then, train stop control is performed (step S315), and when normal (step S310; Y), it is checked whether or not the blocking between point markers is normal (step S311). In the block check between point markers, a block section is fixedly set based on the point marker, and it is checked whether or not the block within each block section is secured.
[0049]
When the blocking between point markers is abnormal (step S311; N), train stop control is performed (step S315), and when normal (step S311; Y), the control pattern is checked (step S312). For example, the control pattern is checked by checking whether the speed control of each train is normally performed based on the history of changes in the position of each train. When there is an abnormality in the control pattern (step S312; N), train stop control is performed (step S315).
[0050]
If the above inspection is normal (step S312; Y), it is checked whether the train has arrived at the station and stopped at a predetermined fixed position (step S313). (Step S313; N), the processing after Step S304 is repeated. If the vehicle stops at a fixed position (step S313; Y), it is checked whether the vehicle and the platform door are normally controlled (step S314). If there is an abnormality, the train stop control is performed thereafter. If (Step S315) is normal (Step S314; Y), the process returns to train schedule management (Step S301), and the process is continued.
[0051]
The on-board device 200 of the train 5 checks the normal / abnormality of the information transmission state between the vehicle and the ground, and in the case of a transmission abnormality (step S405; N), a train for forcibly stopping the own train. Stop control is performed (step S417). If the transmission state is normal (step S405; Y), ATO control (automatic train operation) is performed (step S406). Moreover, a point marker is detected (step S407), the own train position calculation process is performed, and the own train position is updated (step S408). Furthermore, each check of the point marker sequence, the time between the point markers, and the block between the point markers is performed (steps S409, S410, S411), and if any abnormality is found (step S409; N or S410; N or S411; N), train stop control is performed (step S417).
[0052]
If these inspections are normal (steps S409; Y and S410; Y and S411; Y), an on-board pattern is generated (step S412), and the speed control of the train is performed based on this.
[0053]
It is checked whether the train speed is controlled according to the generated on-board pattern. If there is an abnormality (step S413; Y), train stop control is performed (step S417). When the train speed is normally controlled (step S413; Y), the stop control to the station is performed thereafter (step S414), and the fixed position stop is confirmed (step S415). (Step S416), and the process returns to the process of waiting for the input of the next course information (step S401).
[0054]
As described above, since inspections such as the point marker sequence, the traveling time between the point markers, and the blocking between the point markers are performed by both the ground device 100 and the on-board device 200, the safety is improved.
[0055]
FIG. 5 shows a case where the speed control of the train is performed based on the block between the point markers. When the train speed is controlled based on the block between the point markers, the speed is controlled based on the section maximum display data and the display expansion data. In the example of FIG. 5, since the preceding train 502 is present in the forward block section 512 of the closed section 511 where the own train 501 is present, the own train 501 needs to be stopped before entering the forward block section 512. For this reason, the speed of the own train 501 is controlled so as to stop before the predetermined margin distance Ls from the forward block section 512 as shown in FIG.

FIG. 6 shows an example of on-board pattern control for controlling the speed of the train based on the distance to the preceding train. In this case, since the traveling distances L1 and L2 from the last passage point marker of each train are grasped, the distance from the own train 501 to the preceding train 502 is accurately recognized by combining with the distance information of the block section 511. be able to. For this reason, the speed of the own train 501 is controlled to stop just before the margin distance Ls from the tail of the preceding train 502 as shown in FIG. As described above, when the on-board pattern control is performed, the driving time interval can be further shortened, and the arrangement interval of the point markers 110 can be set longer.
[0057]
In this embodiment, on-board pattern control is first performed when the distance between the point markers is secured and there is no abnormality in the data related to the travel distance and the distance between trains can be accurately grasped. . Therefore, the arrangement interval of the point markers 110 is set in consideration of the control between the point markers when there is an abnormality in data such as the travel distance.
[0058]
In the embodiment described above, information related to the preceding preceding train is transmitted to each train. However, information related to two or more preceding preceding trains may be provided. .
[0059]
【The invention's effect】
According to the automatic train control device according to the present invention, each train recognizes the position of its own train on the basis of the point information from the point markers distributed along the rail, and transmits it to the ground device. The position information of the preceding train is acquired and the speed of the own train is controlled according to the distance between the own train and the preceding train. Therefore, the distance to the preceding train can be grasped in detail only by shortening the location interval of the point marker. In comparison with the case where the track circuit is subdivided, the operation interval can be shortened with a small capital investment.
[0060]
  Also,Travel distance detection means for detecting the travel distance of the own trainBecause it is providedThe current position of the own train is detected based on the point information from the point marker and the travel distance detected by the travel distance detection means.ByThe position of the train can be grasped in more detail. Moreover, the arrangement interval of the point markers can be increased.
[0061]
If there is an abnormality in the detection of the travel distance, speed control is performed based on a fixed block section set with reference to the point marker, and if the detection of the travel distance is normal, the distance to the preceding train is set. In the case where the speed control is performed based on the above, it is possible to continue the operation of the train even when the detection of the travel distance is abnormal while ensuring the fine speed control at the normal time.
[0062]
In the case where the train speed control is performed based on various information stored in the on-board database and the distance between the preceding train, more accurate control can be performed in accordance with the course condition and the like.
[0063]
In addition, in order to detect an abnormality in the train position based on at least one of the detection order of the point markers, the traveling distance between the point markers, and the traveling time between the point markers, the apparatus abnormality is accurately detected. Safety can be increased. Furthermore, in the case where both the on-board device and the ground device inspect whether there is an abnormality related to the speed control of the train, since the abnormality is checked twice, the safety can be further improved.
