Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a vehicle traffic system in which a vehicle travels on a track, such as a train or a monorail, based on blockage control. The present invention relates to an on-rail management system and an on-rail management method.

[0002]

2. Description of the Related Art In general, in a vehicle traffic system such as a railway, operation is performed by block control in which a section between stations is a block section. In the case of this blockage control system, "departure" is normally localized, and "stop" is displayed on the traffic light on the entrance side of the blockage section where the vehicle is located.

[0003] In such a vehicle traffic system, as a means for detecting the presence state of a vehicle, a detection system capable of continuously detecting all lines by a track circuit or the like is used. As a result, when the detection system is activated, all traffic signals rise as "departure (G)", but the timing of the rise differs depending on the vehicle position. can do.

[0004] As a result, immediately after the start of the detection system, it is possible to cause all of the traffic lights to display a signal whose safety is ensured. That is, the traffic light on the entrance side of the closed section in which the vehicle exists is automatically controlled to be turned off (stop). The succeeding vehicle is driven in response to a signal indicating that the present state is “stop”, which is a position ahead of the own vehicle.

[0005]

However, the above-described on-rail detection method is applicable only to the case of continuous detection, and a detection device such as an antenna is placed on a track in order to simplify the detection configuration. In the case of a traffic system that is laid discontinuously along the road, it is not possible to perform on-rail management based on reliable and accurate block control when the system is started.

[0006] For example, when the antenna is laid in a spot on a track such as a station or a vehicle passing section, an example of the state can be schematically represented as shown in FIG. In this case, when the vehicle traffic system is activated, the location of the vehicle M1 located on the antenna 2 can be detected, but the location of the vehicle M2 located between the antennas 3 and 4, as shown in FIG. Can not. Therefore, the antenna 2 which should originally indicate "stop" by the closing control indicates "departure", and the antenna 3 cannot receive the information of "departure and ID" for the vehicle M2, and therefore, is shown in FIG. As described above, there may be a problem in safety in the on-rail management.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the prior art, and has been developed in a vehicle traffic system for detecting an on-line state of a vehicle by a discontinuous detection method.

Embodiments of the present invention will be described below with reference to the accompanying drawings.

(First Embodiment) Referring to FIGS.
An on-rail management system for a vehicle traffic system according to the first embodiment will be described.

FIG. 1 schematically illustrates an outline of a vehicle traffic system 1 equipped with an on-rail management system. As shown in FIG. 1, the vehicle traffic system 1 is formed as a system in which a vehicle M travels on a track 11 as a track.

The vehicle M may be a single vehicle, a vehicle in which a plurality of vehicles are mechanically hard-coupled, or a plurality of vehicles in a platoon formed by a computer system. The vehicle may be a so-called soft-connected vehicle whose operation is controlled to form a vehicle. Further, the vehicle is not limited by the type of the power unit, and may be an engine vehicle or an electric motor vehicle. Further, the vehicle is not limited to the type, and may be, for example, a bus, a train, a passenger car, or the like.

Further, the vehicle traffic system 1 can be applied to an existing railway system, monorail system, or the like. In addition, the IMTS system has a traffic network connected by a dedicated road and a general road network connected in a three-dimensional way to the traffic network. (Int
elligent Multi-Mode Trans
IT System) or IGTS (Intelligent Gu) in which a dedicated road is drawn in a closed loop
It may be carried out in an idle transit system.

As shown in FIG. 1, this vehicle traffic system 1
Are a plurality of antennas 12 for signal transmission / reception and detection.
(: 12a, 12b, 12c,...) Are discretely (discontinuously) laid along the line 11. Each antenna 12
Is a communication device 13 (: 13) formed of, for example, a loop antenna capable of transmitting and receiving radio waves and provided for each channel.
a, 13b, 13c,...).

The communication device 13 functions as an interface for performing communication with the vehicle M via the antenna 12 based on a command from the travel control device 14 or the vehicle M. The traveling control device 14 is configured by a computer device that plays a central role in controlling and managing the system. For this reason,
The computer device also includes a recording medium in which software program data for executing the control and management is recorded in advance. Such control and management includes, in addition to traffic control, traveling control and road-vehicle communication control, on-rail management according to the present invention. These antenna 12 and communication device 1
3 and the traveling control device 14 are equipped as roadside facilities.

On the other hand, the vehicle M has a communication device 21 capable of communicating with the track side antenna 12 via radio waves,
A vehicle control device 22 that exchanges necessary information with the vehicle control device 14 on the road surface via the communication device 21 and controls the driving of the vehicle M based on the communication result is provided. The vehicle control device 22 is configured by a computer device and operates based on a predetermined software program. The road-to-vehicle communication is not limited to radio waves, and can be performed by optical communication.

In this vehicle traffic system 10, the positional relationship between the track 11 and the antennas 12 (12a, 12b, 12c,...) Is schematically and representatively represented. As an example, a plurality of antennas 12a, 12b, Are set as closed sections C1, C2,.... As a specific example, as shown in FIG.
1, S2, S3,..., The line 11 forms a branch for passing each other, and the stations may be connected to each other by a single line, and are connected to the ascending and descending branches of each station, respectively. The antennas 12a-1, 12b-1 (12a-2, 1
2b-2, 12a-3, 12b-3,...) Are provided. Further, as shown in FIG. 3, a passing part EX may be formed between the same station parts as described above. Furthermore, as shown in FIG. 4, the track 11 is completely double-tracked,
Antenna 1 for each of the upper and lower lines of 1, S2, S3, ...
2a-1, 12b-1 (12a-2, 12b-2, 12
a-3, 12b-3,...) may be provided. Further, although not shown, the present invention can be similarly applied to a lead-in portion from a main line, a railroad crossing portion, and the like.

Next, the operation and effect of the vehicle traffic system 1 will be described focusing on the on-rail management according to the present invention.

FIG. 5 shows that the traveling control device 14
The outline of the travel control including the above-mentioned on-rail management executed between the vehicle and the vehicle will be described. This on-rail management is particularly important when the vehicle traffic system 1 is started.

When the vehicle traffic system 1 is activated, the traveling control device 4 starts up with the activation and starts the processing shown in FIG. In other words, when the power supply rises, the signal display for all the antennas 12a, 12b, 12c,... Is set to "stop" as an initial setting (step S).
1). Therefore, the vehicle control device 22 of the vehicle M stopped on the antenna 12a before the system is activated, for example,
By this signal indication, it is instructed to maintain "stop". The same applies to another vehicle stopped at another antenna position before the system is started.

Next, the travel control device 14 calls the vehicle M by communication via all the antennas 12a, 12b, 12c,... (Including the identification of the vehicle) (steps S2 and S3).

In the case of the vehicle traffic system 10, the vehicle M
Is always stopped on the antenna 12 and the operation is terminated or interrupted unless it stops at a position halfway between the antennas. For this reason, the interrogation of all the antennas 12 can reliably detect a vehicle other than a vehicle that has stopped due to a failure. In other words, the vehicle with the ID number that has been leaked from this detection can be recognized as a vehicle that has stopped halfway, and takes other necessary measures.

As a vehicle detection method other than the method of interrogating all the antennas 12, the interrogation is performed by wide area radio, the approximate position of the vehicle is grasped, and the interrogation to each of the above-described antennas is performed. It may be. Thus, when there are many antennas, efficient on-rail detection can be performed. In addition, when this method is used, the approximate position of the vehicle can be known by wide-area wireless communication. Therefore, even if there is no response after calling for a certain time by each antenna, the stop position of the vehicle can be estimated to some extent.

As a result of the on-rail detection, if the on-rail status of all the vehicles M can be confirmed and it can be determined that the on-rail status is normal (step S4), the on-rail management based on the "stop" localization taking over the confirmed position is performed. (Steps S5, S5
6). However, conversely, when there is a vehicle that cannot detect the presence of a line, or when there is a vehicle that is stopped at a position other than the regular stop position, necessary measures are taken according to a predetermined manual. Then, when the situation returns to the normal state, the process shifts to the control of the on-rail management based on the “stop” localization (steps S7 and S8).

FIG. 6 shows an example of the on-rail management based on the above-mentioned "stop" localization. 1, the antennas 12a, 12b, 12c,... Shown in FIG.
2, 3, ....

In this on-rail management method, after the on-rail check at the start of the system as described above, all the antennas 1 functioning as a traffic light are checked.
The signal indication according to 2 is once set to "stop", and from this state, a "departure request" is issued from each vehicle for each predetermined blocked section on the front track of each vehicle. In response to this request, the traveling control device 14 performs various controls such as blockage control and interlocking control, confirms safety from the results, and sets the signal indication of the antenna requested to departure to “departure”. change. Then, the signal indication of the antenna detecting the departure (passing) of the vehicle is returned to "stop" again.

For example, in the initial state, as shown in FIG. 6 (a), the preceding vehicle M1 is parked on the antenna 4, and the following vehicle M2 approaches the first antenna 1 of the starting 11 which is the main line, for example, from the drop-in line. Suppose you are. The first antenna 1 has a signal indication of "always departure", but the other antennas 2 to 5 have a signal indication of "stop" due to "stop" localization.

The vehicle control device 22 of the following vehicle M2 that has traveled to the first antenna 1 transmits necessary information such as an ID number to the travel control device 14 via the antenna 1, and transmits the necessary information such as an ID number. To receive necessary operating information such as speed, acceleration / deceleration, stop, departure, etc. Along with this transmission, the following vehicle M2, as shown in FIG.
To the travel control device 14 via the. The traveling control device 14 uses the antenna “2-3-
The two sections between “4” and “4” are defined as a closed section CS (excluding the position on the antenna 4), and a closing control is performed to determine whether or not another vehicle exists in the closed section CS. This closing control is, for example,
This is performed by recording the vehicle that has passed through the antennas 2, 3, and 4 and checking the presence of the vehicle based on the current call to the antennas 2, 3, and 4.

As a result of the closing control, when it is confirmed that no vehicle exists in the closing section CS, the travel control device 14
Changes the signal display for the antenna 2 from "stop" to "departure" in response to the departure request of the following vehicle M2, as shown in FIG. 6 (c). For this reason, the following vehicle M2 that has traveled toward the antenna 2 performs a predetermined transmission and reception on the antenna 2 with respect to the signal display in the antenna 2 =
Receiving the information of "departure" and recognizing the driving permission.

As shown in FIG. 6D, the succeeding vehicle M2 also issues a departure request to the next antenna 3 on the antenna 2 in the same manner as described above. In response, the travel control device 1
No. 4 sets two sections between the antennas “3-4-5” as the next block section CS and performs block control. However, in this case, since the preceding vehicle M1 continues to stop at the position of the antenna 4, the result of the closing control is that traveling is not permitted. Therefore,
“Stop” is maintained in the signal display for the antenna 3.

The following vehicle M2 traveling toward the antenna 3 according to the signal signal of "departure" of the antenna 2
“Stop” is displayed on the antenna 3. Therefore, FIG.
As shown in (e), the following vehicle M2 cannot travel any more,
The vehicle stops or continues to stop at the position of the antenna 3.
Then, a signal of “stop” is given to the rear antenna 2 by the closing control. In addition, the following vehicle M2 stopped on the antenna 3 continuously issues a departure request, and waits until the front closed section becomes empty.

Communication between the vehicle and the travel control device on the antenna can be performed in any of a normal travel state, a deceleration state, and a stop state of the vehicle.

In the case of the "stop" localization control method, the "departure" signal only needs to be displayed on the antenna (signal device) that has requested departure, so that control conditions other than the blockage control can be easily performed. Can be added. This management method can be applied to stations, branches, junctions, railroad crossings, and the like, and the on-rail management system is highly versatile.

As described above, the first embodiment has described the on-line management method at the time of starting the system and subsequent to it. In particular, when the system is started, the signal indications of all antennas are always set to "stop" once, and the presence of all vehicles is detected. For this reason, even in the case where the on-rail management is performed by the discontinuous detection method, the safety management at the time of starting the system is thoroughly performed, and the measures for preventing accidents and the like are thoroughly performed. Further, since the discontinuous detection method is employed, the configuration and signal processing for detection can be simplified and the equipment cost can be reduced as compared with the case of employing the continuous method.

In this embodiment, the on-rail status of all vehicles is detected when the system is started, and if it is in a normal state, the on-rail management method of performing the closing control in the "departure" localization can be adopted thereafter. .

(Second Embodiment) Referring to FIGS.
An on-rail management system for a vehicle traffic system according to a second embodiment will be described. In the following embodiments, the same or equivalent components as those in the above-described first embodiment will be denoted by the same reference numerals, and description thereof will be omitted or simplified.

The on-rail management system according to the second embodiment relates to ensuring release of a block section reserved by block control.

The vehicle traffic system according to this embodiment is constituted by a system that is the same as or equivalent to that of FIG. 1 described above in terms of hardware. In this system configuration, the travel control device 14 performs the processing outlined in FIGS. 7 and 8 for releasing the reservation of the above-described closed section. These processes are performed, for example, in step S5 in FIG. 5 described above.

FIG. 7 shows the on-vehicle on-vehicle detection processing performed by the travel control device 14 for each antenna 12a (12b, 12c,...). The traveling control device 14 performs an interrogation (communication) with respect to the passing vehicle via each of the antennas 12a, 12b, 12c,... Every fixed minute time Δt, and obtains information such as an antenna position, a vehicle ID, and time (Step S).
11), the information is stored in a table, for example (step S12). Thus, the antennas 12a and 12a
b, 12c,... The vehicle on top can be grasped almost in real time.

The on-rail management process shown in FIG. 8 is performed for each antenna, and is performed in parallel with the on-rail detection process of FIG.

The traveling control device 14 determines whether or not a certain vehicle is requesting a departure through a certain antenna (referred to as antenna 1) (step S21). If there is no departure request from the vehicle, the process is terminated and the next process is waited.

When there is a departure request, blockage control is performed for a predetermined blockage section in front of the antenna 1 where the request was made (step S22). It is determined whether or not the travel can be reserved (step S23). NO in this judgment
In the case of, that is, when a preceding vehicle is present in the predetermined block section, the signal for the antenna to which the departure is requested (for example, the antenna 2) is indicated (held) as “stop” (step S24), and after Δt time Wait for reprocessing.

On the other hand, Y is determined in step S23.
ES, that is, when it is possible to make a reservation for traveling in a predetermined block section,
The vehicle control device 14 causes the signal of the antenna 2 of the departure request destination to be displayed as "departure" (step S25).

Next, the vehicle control device 14 reads out the on-rail information on the antenna 2 of the departure request destination obtained in the on-rail detection processing of FIG. 7, performs the closing control, and “stops” the required antenna 1. This indicates that the predetermined block section has already been reserved (step S26).

Next, the traveling control device 14 reads the on-rail information from the antenna 2 to which the departure is requested (that is, the antenna 2 located next to the antenna 1 which has issued the departure request) (step S27). This on-rail information is also obtained almost in real time by the processing of FIG. By reading the on-rail information, it is determined whether or not the vehicle has arrived at the antenna 2 of the departure request destination and communication is normally performed (step S2).
8). As a result, in the case of vehicle arrival and normal communication, the stop instruction for the rear predetermined antenna 1 is set in a releasable state, and the reservation release processing of the closed section is performed (Step S).
29). The process of enabling the stop instruction to be released is performed by, for example, a flag process in the travel control device 14.

However, in the determination in step S28, the travel control device 14 has failed in communication (including incomplete communication) via the antenna 2 to which the departure is requested due to a communication error or antenna failure. In this case (or when there is a suspicion of failure: for example, when there is no response after a certain period of time), the on-line information by the next antenna (referred to as antenna 3) is read (step S30). This on-rail information is also obtained almost in real time by the processing of FIG. Based on the on-rail information, it is determined again whether or not the vehicle has reached the antenna 3 and communication has been normally performed (step S).
31).

If the determination is YES, that is, if the communication is normal, the above-described reservation cancellation processing (step S29) is performed. If the determination is NO, an instruction is issued to take necessary measures such as a deceleration instruction and a manual mode operation. (Step S32).

An example of the above-described on-rail management will be described with reference to FIG. The configurations of the activation 11 and the antennas 1 to 5 are the same as those in FIG. Specifically, FIGS. 9A and 9B
As shown in FIG. 7, the preceding vehicle M1 issues a departure request and travels while reserving the closed section CS based on the result of the closed control. At the same time, a stop instruction is issued to the rear antenna by closing control of the vehicle traffic system 14 (for example, the antenna 1 for the antenna 2 in FIG. 9B).

In such a situation, for example, FIG.
As shown in the figure, it is assumed that communication with the vehicle has failed due to a communication error or an antenna failure in the antenna 4 located on the entrance side of the reserved closed section CS as described above. in this case,
By the processing of steps S27 to S31 in FIG.
As shown in FIG. 9D, the preceding vehicle M <b> 1 is subjected to the retroactive processing of canceling the reservation of the closed section based on the detection of the presence of the next antenna 5. Specifically, when normal communication is performed by the antenna 5 and the presence of a line is detected, the travel control device 14 simultaneously performs a process of releasing a stop instruction to the antennas 2 and 3 (reservation release of a closed section).

In this case, the cancellation of the reservation for the antenna 3 is the coverage area of the on-line detection by the antenna 5, whereas that of the antenna 2 is originally the coverage area of the on-line detection by the antenna 4. In the present embodiment, the reservation release processing is duplicated in consideration of communication errors with the antenna after the reservation of the closed section, so that even if communication fails with the antenna 4, communication with the antenna 5 is almost assured. The reservation is released. Therefore, for example, as shown in FIG. 9D, a departure request issued from the following vehicle M2 that has arrived at the antenna 2 is accepted, and it is possible to newly reserve a blockage area between the antennas 3 to 5 and continue traveling. it can.

Conversely, in this case, in this case, the preceding vehicle M
If communication with antenna 1 is unsuccessful with antenna 4 and no cancellation command is issued based on the antennas after antenna 5, the succeeding vehicle M2 that has reached antenna 2 has not been released from the closed section of preceding vehicle M1. After 2, the vehicle cannot run forever. However, according to the present embodiment, the reservation release of the closed section is duplicated, so that in most cases, the probability that communication is normally performed with two continuous antennas is high, and such a subsequent vehicle cannot travel. Can be automatically and reliably eliminated. Therefore,
There is almost no need for a central guard to manually reset.

Although there may be a slight time delay, from the viewpoint of improving the ability to cancel the reservation of a closed section, the above-described processing is applied to three or more continuous antennas to perform normal communication. Sometimes, the reservation cancellation for the antenna related to the communication failure up to that time may be simultaneously performed retroactively.

The above-mentioned reservation canceling method is a method that exhibits high resistance to transient communication errors and failures of one antenna. However, the reservation canceling method of the vehicle-side communication device (including the vehicle-side antenna). It is difficult to deal with continuous communication errors such as failures. Therefore, in this case, a so-called time interval method is used in which a stop instruction can be released (reservation release) at a point in time after passing through the antenna (for example, twice as long as the normal traveling time). do it. However, in the case of this method, since the on-rail status is not actually confirmed after the release, information indicating that the release is based on the time interval method is provided when the signal "departure" is displayed from the antenna. Send to the vehicle together. On the vehicle side, based on this information, the operation may be controlled so as to perform low-speed driving and manual driving (visual driving) of the driver.

Further, the above-described time interval method can be similarly implemented even when a plurality of antennas are out of order. That is,
The time interval method can be applied if communication can be performed even once in a section in which safety is secured by fixed occlusion. If the vehicle is stopped due to an accident or the like (that is, the vehicle is not traveling at a normal speed), the vehicle transmits the fact to the central travel control device to understand such a situation. Good. Thereby, it is possible to shift from the traveling mode in which the traveling is continued using the time interval method to the emergency stop mode. At this time, if a wide-area wireless device is provided, the emergency stop can be automatically performed using the wide-area wireless communication, or the driver can be caused to perform an emergency stop.

In the case of a system that can use wide-area wireless communication, the position of a vehicle can be detected via wide-area wireless communication. Therefore, the detection information can be used to perform processing to supplement the above-described communication failure by the antenna. In some cases, blocking control (moving blocking) using only wide-area wireless communication can be performed.

(Third Embodiment) With reference to FIGS. 10 to 13, an on-rail management system for a vehicle traffic system according to a third embodiment will be described.

The on-rail management system according to the third embodiment relates to ensuring reservation of a block section based on block control.
In particular, the second embodiment described above is intended to reliably release the blockage section with respect to the succeeding vehicle even when a communication error or failure occurs between the vehicle and the ground side. On the other hand, it is an object of the present embodiment that the own vehicle can reliably reserve its own closed section even when a similar situation occurs. For this reason, the processes related to the closed sections according to the second and third embodiments can be performed in combination, and it is possible to provide an on-rail management system with significantly improved resistance to communication abnormalities and communication failures.

The vehicle traffic system according to this embodiment is constituted by a system which is the same as or equivalent to FIG. 1 described above in terms of hardware. In this system configuration, the travel control device 14 performs the processing outlined in FIGS. 7 and 11 for the reservation of the above-described closed section. Among them, the processing in FIG. 7 has already been described in the second embodiment. These processes are performed, for example, in step S5 in FIG. 5 described above.

The traveling control device 14 starts the on-rail management process based on FIG. 10 for each antenna. First, on-rail information (vehicle I) based on a certain antenna (referred to as antenna 1)
D, including the vehicle group ID), and attempts to detect the vehicle on the antenna 1 (steps S41, S42).

Since the vehicle may not be detected normally due to abnormal reception of the antenna or abnormal transmission of the vehicle, the above detection is performed in addition to the determination of the elapsed time from a predetermined reference time related to the operation of the vehicle. It is processed.

Next, the travel control device 14 determines whether or not the communication for reading the on-rail information has been normally performed (step S43). When communication is normally established, a departure request from the vehicle to the next antenna (referred to as antenna 2) is normally issued at the position of antenna 1. In this case, the next on-rail information by the antenna 2 is read out, and the same vehicle detection is attempted (steps S44 and S45). This vehicle detection indicates that the vehicle has reached the position of the antenna 2.

Therefore, the traveling control device 14 receives a departure request for the next block section issued from the vehicle to the antenna 3 via the antenna 2, and executes the block control (steps S46 and S47). Thereafter, the on-rail management based on the first and second embodiments and the closing control is performed.

On the other hand, if it is determined in step S43 that the communication is not normally established (NO), the departure request at the position of the antenna 1 is not transmitted to the device 14 side or is very vague. It is transmitted only with low accuracy. After all, it is considered that a departure request has not been issued, and the processes of steps S48 to S50 are performed.

That is, the on-board information by the next antenna 2 is read, and the on-board detection of the vehicle at the position of the antenna 2 is performed (steps S48 and S49).
When this vehicle detection is achieved, the vehicle issues a departure request for the current position, that is, the antenna 2 to the travel control device 14 via the antenna 2 and accepts it (step S50). In response, the travel control device 14 changes the signal indication to the antenna 2 to "departure" (step S51).

Thereafter, the traveling control device 14 receives a departure request for the preceding closed section in step S46. As described above, when communication is not normally established, a departure request is issued to the antenna at the position of the antenna indicating the "stop" of the signal, and then a departure request is made to the front blocked section. In this method, a reservation method for a closed period after a two-stage departure request is used.

For example, as shown in FIGS. 11A and 11B, it is assumed that the trajectory includes an entrance of a straight line or a curved line. In this case, the antenna 1 at the entrance is always signaled "Departure".

Now, as shown in FIG. 11A, the vehicle M
It is assumed that communication has not been established with the antenna 1 at the entrance, that is, the antenna 2 has been reached without making a departure request for the next antenna 2 (or in such a state that it can be regarded as such). At this time, the departure request 1 for the own antenna 2 is first issued and the signal indication "stop" is changed to "departure" by the processing through steps S50, S51 and S46 described above. Next, the departure request 2 for the next antenna 3 is issued as in the normal state, and the routine shifts to the normal closing control.
For this reason, even if the vehicle passes through the antenna 1 while communication is not established, it is possible to reserve a blockage section ahead of the antenna 2 without any trouble.

FIG. 12 shows a comparison of this case with a process that does not issue a departure request 1 to its own antenna 2.
(A) and (b) are displayed. In this case, the antenna 2 cannot restart because there is no means for canceling the stop instruction for the antenna 2 itself. However, according to the present embodiment, such a locked state can be reliably released, a closed section can be reserved smoothly and stably, and traveling can be continued.

In the above-described example, the method of reserving an occluded section when communication is not established in the antenna at the entrance of the straight or curved portion of the track is described. The same applies to the case of failure, and it is possible to travel while requesting a departure to the next closed section. This is schematically shown in FIG. In this case, communication is not established in the antenna 2 and a departure request to the antenna 3 cannot be issued. Therefore, the antenna 3 first issues a departure request 1 to its own antenna 3 to release the stop instruction, and then issues a departure request 2 to the next antenna 4. As a result, the locked state is reliably released, and traveling based on the closing control is enabled.

Further, the communication failure in the present embodiment is caused not only by the above-described situation relating to the abnormality of the communication itself, but also by
The communication is normally performed once, and the departure request is normally accepted, but the device controlling the requested antenna is temporarily reset, and the "departure" signal indication state is lost. .

Further, as a control variant, always
A departure request may be simultaneously issued to two closed sections, a “next closed section” and a “next closed section”. Thus, even when a communication error occurs temporarily, the self-lock of the antenna can be released by applying the method of the above-described embodiment when the next antenna arrives. Simultaneously with this release, it is preferable to recognize that communication has not been established in the front antenna and issue a warning indicating such a situation.

Further, when the self-lock release method of the present embodiment is used, even when the system is restarted in a state where the vehicle group is in the closed section due to the occurrence of an equipment abnormality or the like, the reservation of the closed section (that is, the reservation of the closed section) It is not necessary to perform a special process for the departure request), the process can be started easily, and the complication of the process can be eliminated.

By the way, as another configuration different from the present embodiment, an antenna (a signal antenna, a detection antenna) having a sufficiently long length (a length effective for communication is sufficiently long) is adopted. It may be. In this case, there is a time margin from when the vehicle gets on the antenna to when the braking command is issued. For this reason, it may always be controlled to issue a departure request only for the next block section, and if communication fails, it will stop on that antenna,
It is free from the above-mentioned problem of running on the next antenna and locking there.

Note that the present invention is not limited to the configuration of the above-described embodiment, and it is needless to say that various modifications can be made based on the gist of the claims.

In addition, at the time of reservation and release of the block section based on the block control, it is possible to perform the on-line management based on the block control reliably and accurately while performing relatively simple processing.
