JP4575054B2 - Level crossing system and level crossing control method - Google Patents

Description

  The present invention relates to a crossing system and a crossing control method for performing a crossing operation of a crossing in relation to a train.

  The opening time of railroad crossings tends to be shorter due to the longer trains and higher train operation. For this reason, a so-called “unopening level crossing” occurs, causing traffic congestion on the surrounding roads.

  In Patent Literature 1, railroad crossing control is performed based on train position / speed information obtained via a wireless network. When a train enters the platform and stops, the crossing operation of the level crossing in the overrun protection section in the traveling direction of the train is stopped. When the alarm duration at a railroad crossing exceeds a predetermined time, the alarm start time and the alarm end time in each traveling direction are predicted, and the approach of the train approaching the alarm start point to the alarm start point is delayed. If the railroad crossing is inoperable, the approach traveling to the railroad crossing is stopped.

  In Patent Document 2, railroad crossing control is performed based on train position / speed information detected on the ground side by radio using a coaxial leakage cable. In Patent Document 2, a travel distance required for a train to stop before a railroad crossing is calculated to set a crossing control start point, and when the train position substantially coincides with the crossing control start point, It is determined that a train is detected at the control start point, and alarm control is started.

  In Patent Document 3, when a railroad crossing control command is transmitted from a train that travels according to a preset traveling control pattern and a response signal and a normal railroad crossing signal are received from the railroad crossing control device, the vehicle stops immediately before the railroad crossing. The stop pattern (crossing stop traveling control pattern) is deleted.

  The existing level crossing systems as described above can be mainly divided into two types.

  The first type is a system that obtains train position / speed information via a wireless network and performs railroad crossing control, and performs railroad crossing control based on train position / speed information detected on the ground side using radio. Includes systems.

The second type includes a system that predicts the time it takes to reach a level crossing on a train and receives a level crossing blocking command from the train to the ground.

  For example, when the train speed is selected quickly and the control is performed to switch the railroad crossing warning time according to the sorting result, the warning time becomes longer if the actual train speed is lower than the train speed corresponding to the sorting result. There is a problem.

  In Patent Document 1 described above, no consideration is given to reducing the alarm time for other level crossings that are not in the overrun protection section. Further, when a delay occurs due to, for example, a decrease in train traveling efficiency, it is necessary to perform train group control in consideration of the influence on the operation schedule. However, in the above-mentioned Patent Document 1, it is difficult to consider the influence on the operation schedule because the railroad crossing is controlled independently.

  In Patent Document 2, the level crossing control start point is determined from the distance required for the train to stop before the level crossing. For this reason, when the train speed is low, a short distance is calculated as the travel distance necessary for the train to stop before the railroad crossing, and the actual warning time is below the lower limit of the warning time set for safety. It can happen.

  In Patent Document 3, as described above, the time required to reach a railroad crossing is obtained according to a preset traveling control pattern, and the timing at which a railroad crossing control command is output is determined. However, it is difficult to predict the time until the railroad crossing is reached for a train for which no traveling control pattern is set in advance.

  In the two types of the existing level crossing system, the second type can shorten the interruption time compared to the first type. On the other hand, the second type is applied when the train travels according to a preset travel control pattern, and is difficult to apply when the train does not travel according to a travel control pattern that is not preset. It is.

  A track circuit is provided for each unit for ascertaining whether or not a train exists on the route. Each track circuit detects whether a train exists for each unit.

The terminal device 6 receives the track circuit ID of the track circuit in which the train line is detected from the track circuit transmission / reception unit 30 and provides the track circuit ID of the track circuit in which the train track is detected to the logic unit 7. The number of open section information received from 7 is transmitted to the track circuit transmitting / receiving unit 30.

  The track circuit transmission / reception unit 30 detects the presence state of the train using the track circuit. Moreover, the track circuit transmission / reception part 30 receives the opening section number information received from the terminal device 6, and transmits the opening section number information to each train via the track circuit.

  The train performance database 14 stores information such as the acceleration / deceleration performance, the train weight, the train length, and the travel resistance of the train 1.

  The route information database 15 stores information such as track circuit arrangement, length, gradient, curve, speed limit, branch position, station position, station route (route), railroad crossing position, number of breaker groups, width, and the like. .

It is also possible to store a new travel control algorithm in the travel control algorithm storage unit 17. A plurality of travel control algorithms are stored in the travel control algorithm storage unit 17, an arbitrary travel control algorithm is selected, and the train 1 may travel according to a travel schedule determined by the selected travel control algorithm. .

  The position correction ground element receiving unit 11 receives position correction information from a position correction ground element 31 installed on the route via a vehicle upper element (not shown) mounted on the train 1.

  The speed / position detector 18 calculates the speed and position of the train 1 based on the pulse signal from the speed generator 12 and the like.

  The receiving unit 10 receives from the track circuit transmitting / receiving unit 30 the number of open sections calculated by the logic unit 7 via a track circuit (not shown) and a train control device power receiver (not shown) mounted on the train 1. .

  Upon receipt of the railroad crossing cutoff command, the alarm control unit 25 performs a series of railroad crossing warning controls (a train approach warning due to a railroad crossing ringing, a drop of the barrier ring, a ringing stop after passing the train, and an increase of the barrier ring). The interruption completion information is provided to the answer back transmission unit 26.

  When the answer back transmission unit 26 receives the cutoff completion information from the alarm control unit 25, the answer back transmission unit 26 transmits the answer back to the stop pattern erasing unit 22 by radio.

  The operation of the railroad crossing system according to this embodiment will be described below.

  FIG. 3 is a diagram illustrating an example of the relationship between the train 1 and the railroad crossing.

When the train 1 approaches a nearest level crossing 32 on its own route (destination) to a certain distance, the operation control unit 2 of the train control device uses the route information database 15 in the cutoff command transmission time determination unit 19. Based on this information, the level crossing 32 that is the target of transmission of the cutoff command is extracted, the alarm time calculation formula read from the alarm time calculation formula database 16, information such as the number of crossing breaker groups and the value of each element time according to the width Based on the information such as the deceleration performance of the train 1 and the running resistance read from the train performance database 14 and the information such as the gradient, curve, and speed limit read from the route information database 15, the train 1 A time T ₁ indicating how many seconds before reaching the entrance the transmission control command should be transmitted is obtained.

In addition, the operation control unit 2 reads information such as the deceleration performance of the train 1, travel resistance, and the like read from the train performance database 14, information such as the gradient, curve, and speed limit read from the route information database 15, Based on information such as the position and speed of the train 1 calculated by the position detector 18, a time T indicating how many seconds the train 1 will reach the entrance of the railroad crossing 32 according to a travel schedule determined by the travel control algorithm. Ask for ₂ .

Then, the operation control unit 2 subtracts T ₁ from T ₂ to determine a time T ₃ that represents a time for transmitting the level crossing cutoff command (or how many seconds after which the level crossing cutoff command should be transmitted).

In the present embodiment, a time T ₁ indicating how many seconds before the train 1 reaches the entrance of the railroad crossing 32 should be determined is obtained as follows.

  First, before the train 1 reaches the entrance of the crossing 32, the crossing of the crossing must be completed. In addition, as a time for the person trapped in the crossing 32 to escape, it is necessary to secure a predetermined time from the completion of the crossing of the crossing until reaching the entrance of the crossing of the train 1. It takes a certain amount of time to notify the train approaching by a railroad crossing and to lower the barrier. Furthermore, it takes a certain time to transmit a signal for crossing the railroad crossing from the train 1 to the ground.

  According to Notification No. 177 of the former Ministry of Transport (current Ministry of Land, Infrastructure, Transport and Tourism), the time from the start of the railroad crossing ringing to the completion of the cutoff is typically 15 seconds, a minimum of 10 seconds, from the completion of the cutoff to the arrival at the railroad crossing entrance The standard time (alarm time) is determined to be at least 20 seconds and at least 15 seconds (Japan Railway Electrical Engineering Association "Introduction to Electricity Signal Series 8 Railroad Crossing Safety Devices for Railway Engineers", ISBN 4- 931273-10-6 p.113).

  Based on this rule and the scale of the level crossing, the time for which the barrier can be lowered, the time required for the barrier to descend, the time from the completion of the stop until the train reaches the railroad crossing (alarm time) ) Is decided at each level crossing.

  On the other hand, for efficient travel, before the start condition of travel control according to the stop pattern is satisfied (crossing the stop pattern), the stop pattern is applied to the operation control unit 2 that has received the answer back from the level crossing control device 3. It is desirable to erase.

  When it is determined that the stop pattern intersects, a brake command is provided from the stop control unit 23 to the brake control unit 13, but it takes a certain time (idle running time) before the brake actually starts to work. Thereafter, the train 1 travels a distance corresponding to the train speed at the start of braking and the deceleration performance of the train, and stops before the railroad crossing entrance.

A section traveling before stopping the brake starts effectiveness of this time the S _P, to the time the interval when the normal running and T _p.

4, it is determined that "cross the stop pattern" is a diagram representing the time T _p according to when the brake is normally traveling and the interval S _P of the section traveling before stopping from the start effectiveness.

Before the brake command is provided from the stop control unit 23 to the brake control unit 13, in order to erase the stop pattern, the operation control unit 2 performs an answerback earlier than the level crossing arrival (free running time + T _p ). It is necessary to receive.

Further, since it takes a transmission time until the answerback is transmitted from the level crossing control device 3 to the operation control unit 2, the time when the level crossing is completed and the level crossing control device 3 transmits the answerback is the entrance of the railroad crossing of the train 1 It must be earlier than the arrival by T ₄ = (transmission time + idle time + T _p ).

Therefore, T ₁ is the transmission time from the operation control unit 2 to the level crossing control device 3, the train approaching notice time due to the level crossing ringing, the time required for the train to descend, and the time from the completion of the level crossing cutoff until the train crossing entrance (alarm time) Of the standard value of 20 seconds and T ₄ , whichever is larger).

FIG. 5 is a diagram showing an example of the contents of time T ₁ in the present embodiment. FIG. 5 is an example in which the stop pattern is erased when the operation control unit 2 receives a railroad crossing cutoff signal. In addition, this FIG. 5 represents the case where the train speed is 110 km / h.

First, T ₁ includes a transmission time of a railroad crossing cut-off command, a blackout descent notice time for notifying a train approaching by a railroad crossing sound, and a cut-off descent time for lowering the crossing rail.

After the crossing of the railroad crossing is completed, it is necessary to secure a standard alarm time of 20 seconds on the one hand before reaching the railroad crossing entrance of the train 1, and on the other hand, the answerback transmission time and idle time (deceleration command) It is necessary to secure T _p (the time from when the brake starts to operate until the vehicle stops and the time when the vehicle travels without decelerating from the start of braking until it stops).

When the train speed is higher than a certain level, the distance required for stopping is long and T _p becomes large. Therefore, T ₄ = (transmission time + idle time + T _p ) exceeds the alarm time standard value of 20 seconds, and the speed is T ₁ increases as the value increases.

When the train speed is low to some extent, the distance required for stopping is short and T _p becomes small. Therefore, T ₄ = (transmission time + idle time + T _p ) falls below the standard alarm time of 20 seconds, and T ₁ Is constant.

  FIG. 6 is a graph showing an example of the theoretical value of the alarm time when a train crossing cut-off command is transmitted from the operation control unit 2 of the train 1 to the crossing control device 3. FIG. 6 is a graph showing an example of the relationship between the railroad crossing arrival time and the speed of the train 1.

From this graph, assuming that the train 1 travels at a constant speed to the entrance of the railroad crossing 32, it is determined that T ₁ is constant when the speed of the train 1 is approximately 80 km / h or less.

The time T ₂ indicating how many seconds the train 1 will reach the entrance of the railroad crossing 32 can be obtained as follows.

  The operation control unit 2 provided in the vehicle upper part 8 of the train control device is based on the number of open sections received from the logic unit 7 of the ground unit 5 and is not opened while the previous train is on the line or during the switch of the branching unit. Or before the area where the train 1 is not permitted to enter due to reasons such as an uninterrupted level crossing, that is, the stop pattern for the train 1 to stop before the end of the opening section, and before the speed limit section Always calculate (update) a deceleration pattern to decelerate to the speed limit.

  The vehicle upper portion 8 includes a stop pattern database. The stop pattern is calculated and stored in advance in the stop pattern database, and the operation control unit 2 selects an appropriate stop pattern from the stored stop patterns. You may choose.

  As long as the start condition of this stop pattern is not satisfied (unless it crosses the stop pattern), the speed limit of the train, the maximum speed determined for each train type, and the maximum speed determined for each station will not be exceeded. The way you run is free.

  The travel of the train 1 in this area is limited by the operation control unit 2 by utilizing the function of the stop control unit 23 (here, the maximum speed for each train type and the maximum determined for each station). (Including speed), the brake may be applied when it exceeds, and the brake may be released when it falls below, or it may be manually operated by the driver, automatic train operation equipment (ATO), etc. You may implement | achieve using a low-order train operation system.

  In the present embodiment, since a travel control algorithm is used for determining the travel schedule, this travel control algorithm is stored in the travel control algorithm storage unit 17.

  There is no restriction on the travel of the train 1 other than the speed limit until the closest stop pattern is crossed. For this reason, how the train 1 will travel in the future can be predicted according to normal traveling logic.

Therefore, information such as the gradient, curve, speed limit, etc. read from the route information database 15, information such as the acceleration / deceleration performance of the train 1 read from the train performance database 14, and calculated by the speed / position detector 18. Based on the position information and speed information of the train 1 and the travel control algorithm stored in the travel control algorithm storage unit 17, the time T ₂ until the train 1 reaches the entrance of the railroad crossing 32 can be predicted. .

When the cutoff command transmission time is reached, the cutoff command transmission unit 20 transmits a railroad crossing cutoff command to the level crossing control device 3 wirelessly. Instead of waiting for transmission of the level crossing cutoff command until the cutoff command transmission time is reached, the cutoff command transmission unit 20 may transmit the level crossing cutoff command and T ₃ together when calculating the cutoff command transmission time.

  The level crossing cutoff command is transmitted from the cutoff command transmission unit 20 to the level crossing control device 3 via communication means such as a coaxial leakage cable (LCX).

When the railroad crossing control device 3 receives the railroad crossing cutoff command by the cutoff command receiving unit 24, the alarm control unit 25 sounds the railroad crossing for a predetermined time and notifies the train approach, and then lowers the rail crossing. In the meantime, when the crossing control device 3 receives T ₃ along with the level crossing cutoff command, it is assumed that the level crossing cutoff operation is performed after the time T _{3 has} elapsed since the reception of the level crossing cutoff command. When the crossing of the level crossing is completed, the alarm control unit 25 provides an answer back to the answer back transmission unit 26.

  The answer back is transmitted from the answer back transmitting unit 26 to the stop pattern erasing unit 22 via a communication means such as a coaxial leak cable.

  When receiving the answer back from the level crossing control device 3, the stop pattern erasing unit 22 erases the stop pattern for stopping the train 1 before the entrance of the level crossing 32. When the stop pattern for stopping at the entrance of the level crossing 32 is deleted, the train 1 travels as scheduled and passes the level crossing.

  When the railroad crossing control device 3 detects the completion of the passage of the train 1, the alarm control unit 25 stops the railroad crossing sound and raises the barrier. The detection of the completion of passage may be detected by detecting the passage of the alarm end point at the tail end of the train using a ground unit, a track circuit, or the like as in the past, or by detecting passage information from the train 1 by radio or the like. It is good.

  If the railroad crossing 32 is not normally cut off due to a failure or the like, the answer back is not transmitted from the answer back transmitting unit 26 to the stop pattern erasing unit 22, and the stop pattern erasing unit 22 does not erase the stop pattern. The vehicle decelerates from where it crosses the stop pattern and stops before the entrance of the level crossing 32.

  In addition, when a crossing trouble occurs, such as when the car cannot move in the crossing 32, and the trouble occurrence from the crossing obstacle detection device or the crossing trouble notification device is received by the operation control unit 2, whether or not the crossing of the crossing is completed. Regardless, the stop pattern is not deleted (if it has already been deleted, it is generated again), and the stop pattern is executed by taking the maximum measures for stopping the train 1 just before the entrance of the railroad crossing 32.

  FIG. 7 is a flowchart showing an example of the operation of the railroad crossing system according to the present embodiment.

  In step S1, the operation control unit 2 of the train control device starts a train control cycle.

  In step S <b> 2, the operation control unit 2 determines whether it has not passed through the level crossing 32 and has approached the level crossing 32 to a certain distance. If it is not determined that the vehicle has not passed through the level crossing 32 and is approaching a certain distance, step S9 is executed.

  If it is determined that the vehicle has not passed through the level crossing 32 and is approaching a certain distance, in step S3, the operation control unit 2 determines whether the cutoff command transmission time is undecided. If the cutoff command transmission time is determined, step S5 is executed.

  If the cutoff command transmission time has not been determined, in step S4, the operation control unit 2 executes a cutoff command transmission time determination process.

  In step S <b> 5, the operation control unit 2 determines whether the cutoff command has not been transmitted although the cutoff command transmission time has come.

  When the cutoff command transmission time is reached but the cutoff command has not been transmitted, in step S6, the operation control unit 2 transmits the cutoff command to the level crossing control device 3, and then step S9 is executed.

  If the cutoff command transmission time is reached but the cutoff command is not determined not to be transmitted, in step S7, the operation control unit 2 determines whether or not an answer back has been received yet without receiving an answer back. To do. If the answerback has not yet been received and it is not determined that a new answerback has been received, step S9 is executed next.

  If it is determined that the answerback has not been received yet and a new answerback has been received, in step S8, the operation control unit 2 deletes the stop pattern for stopping the train 1 before the railroad crossing 32, Next, step S9 is executed.

  In step S9, the operation control unit 2 determines whether or not the train 1 has entered the section represented by the stop pattern.

  When the train 1 has entered the section represented by the stop pattern, in step S10, the operation control unit 2 executes control for traveling according to the stop pattern, and the processing from step S2 onward is performed. Repeated.

  When the train 1 has not entered the section represented by the stop pattern, in step S11, the operation control unit 2 executes control for performing normal traveling, and the processing from step S2 onward is repeated.

  On the other hand, at step U1, the level crossing control device 3 receives the level crossing cutoff command transmitted at step S6.

  In step U2, the level crossing control device 3 executes a blocking operation.

  In step U3, the crossing control device 3 transmits an answer back to the operation control unit 2 when the blocking operation is completed. Thereby, in said step S7 of the level crossing control apparatus 3, it is judged that the answer back was received.

  In step U4, the crossing control device 3 detects the completion of the crossing of the train 1 at the crossing.

  In step U5, the crossing control device 3 performs a crossing opening operation.

  FIG. 8 is a flowchart illustrating an example of the process for determining the cutoff command transmission time in S4.

  In step S <b> 41, the operation control unit 2 determines the travel schedule of the train 1 using the travel control algorithm stored in the travel control algorithm storage unit 17.

In step S42, the operation control unit 2 calculates a traveling time T ₂ of the case where the train 1 has traveled on the basis of the running control algorithm from the present to the inlet of the railway crossing 32.

In step S43, the operation control unit 2 calculates the travel time T _p in the case where the distance required to decelerate according stop pattern for stopping at the entrance before the crossing 32, travels through the normal traveling.

In step S44, the operation control unit 2 represents the time T _p and Availability run time and transmission time, based on the crossing alarm time standard value, whether to send the crossing cutoff command before how much the inlet reaches the crossing 32 Time T ₁ is determined. As described above, in the present embodiment, T ₁ is the transmission time from the operation control unit 2 to the railroad crossing control device 3, the train approaching notice time due to the railroad crossing sound, the time required for closing the railroad crossing, and the completion of the crossing of the railroad crossing. It is obtained as the sum of the time required to reach the entrance to the railroad crossing 32 of the train 1 (the larger of the alarm time standard value 20 seconds and T ₄ ).

In step S45, the operation control unit 2 determines the cutoff command transmission time T ₃ by subtracting from the time T ₂ time T _1.

  In the present embodiment described above, when the train 1 approaches the railroad crossing 32 to a certain distance, a stop pattern for stopping the train 1 before the entrance of the railroad crossing 32 is generated, and the time until it reaches the entrance of the railroad crossing 32 Thus, the shut-off command transmission time is calculated so that the stop pattern erasing timing is just before the stop pattern execution start condition is satisfied while securing the minimum value of the alarm time.

  The level crossing cutoff command is transmitted from the driving control unit 2 to the level crossing control device 3, and when the level crossing 32 is cut off and the answerback is transmitted from the level crossing control device 3 to the driving control unit 2, the train 1 The stop pattern for stopping is deleted.

  Thereby, the interruption time of the level crossing 32 can be minimized as it is not affected by the speed of the train 1. Moreover, when the level crossing 32 is not normally interrupted | blocked, the train 1 can be stopped safely just before the entrance of the level crossing 32 according to a stop pattern.

  Therefore, it is possible to reduce traffic jams caused by prolonging the interruption time of the railroad crossing 32 and to ensure safety.

  Further, in the present embodiment, even when the traveling control pattern is not set in advance, the time for shutting off the level crossing 32 can be shortened based on the traveling control algorithm.

(Second Embodiment)
In the present embodiment, a modification of the first embodiment will be described.

  FIG. 9 is a block diagram showing an example of a railroad crossing system according to the present embodiment.

  The railroad crossing system according to the present embodiment is substantially the same as the railroad crossing system according to the first embodiment, except that the crossing command receiving unit 34 and the answerback transmission unit 35 are connected in the crossing control device 33. Is different.

  In the present embodiment, the answer back transmission unit 35 provided in the level crossing control device 33 is immediately after the level crossing cut-off command is received by the cut-off command receiving unit 34, that is, the time when the cross-cut command is received, and the alarm control unit 36. Simultaneously with the start of the railroad crossing blocking operation, the answer back is transmitted to the operation control unit 39 provided in the upper portion 38 of the train 37.

When the interruption command transmission time determination unit 40 of the operation control unit 39 obtains a time T ₁ indicating how many seconds before the train 37 reaches the railroad crossing entrance, the answerback is simultaneously with the start of the railroad crossing interruption. Considering transmission from the level crossing control device 33 to the operation control unit 39.

That is, the cutoff command transmission time determination unit 40 is a standard for the time for warning the train approaching by the railroad crossing ringing, the time for lowering the gate, and the warning time from when the railroad crossing cutoff starts until the train 37 reaches the railroad crossing entrance. It is necessary to secure a value of 20 seconds, and at the same time, in order to erase the stop pattern before the brake command is generated because it is determined that “cross the stop pattern”, it is more than (running time + T _p ) It is necessary to accept an answer back as soon as possible. Furthermore, it takes a transmission time until the answerback is transmitted from the level crossing control device 33 to the operation control unit 39.

Therefore, the time T ₁ is the transmission time from the operation control unit 39 to the railroad crossing control device 33, the time from the start of the railroad crossing interruption to the arrival of the railroad crossing entrance (the time taken from the start of the railroad crossing interruption to completion = the train due to the railroad crossing ringing) It is calculated as the sum of the advance notice time + the descent time of the shut-off canon + the standard value of the alarm time of 20 seconds and T ₄ = the transmission time + the idle time + T _p , whichever is larger.

FIG. 10 is a diagram illustrating an example of the contents of the time T ₁ in the present embodiment. FIG. 10 shows an example in which the stop pattern is erased when an answer back (shutoff command reception signal) is received. In addition, this FIG. 10 represents the case where the train speed is 110 km / h.

First, it is necessary to obtain the transmission time of the level crossing cutoff command from the operation control unit 39 to the level crossing control device 33. After the start of the crossing of the railroad crossing, by the time the train 37 reaches the railroad crossing entrance, on the other hand, a time for notifying the train approaching by the sound of the railroad crossing, a time for lowering the crossing rail, and a standard value of the alarm time of 20 seconds are secured. On the other hand, the answerback transmission time, idle running time (time from when the deceleration command is issued until the brake starts to work), and T _p (the section where the brake runs from when the brake starts to stop) Time when the vehicle travels without deceleration).

When the train speed is higher than a certain level, the distance required for stopping is long and T _p becomes large. Therefore, T ₄ = (transmission time + idle running time + T _p ) exceeds the time taken from the start to completion of the level crossing, As the speed increases, T ₁ also increases.

When the train speed is low to some extent, the distance required for stopping is short and T _p becomes small. Therefore, T ₄ = (transmission time + idling time + T _p ) is less than the time taken from the start to completion of the crossing, T ₁ is constant.

By examining FIG. 6 above, when it is assumed that the train 37 travels at a constant speed to the railroad crossing entrance, the speed at which T ₁ is constant is considered to be approximately 160 km / h or less.

  In addition, about another operation | movement of a level crossing system which concerns on this Embodiment, it is the same as that of the level crossing system which concerns on the said 1st Embodiment.

  FIG. 11 is a flowchart showing an example of the operation of the crossing system according to the present embodiment.

  Steps V1 to V3, V5 to V11, W1, W4, and W5 in FIG. 11 are the same as steps S1 to S3, S5 to S11, U1, U4, and U5 in FIG.

  FIG. 11 is different in that the order of the answer back transmission and the level crossing blocking operation in the level crossing control device 33 is opposite to that in FIG.

  The level crossing control device 33 transmits an answer back to the operation control unit 39 when a level crossing cutoff command is received in step W2. As a result, it is determined that the answer back has been received in step V7 of the crossing control device 33.

  In step W3, the level crossing control device 33 performs a level crossing blocking operation.

  Further, in FIG. 11, a part of the determination process of the cutoff command transmission time in step V3 is different from the determination process of the cutoff command transmission time in S4 of FIG.

As described above, the determination process of the interruption command transmission time in the present embodiment is based on the transmission time T ₁ from the operation control unit 39 to the railroad crossing control device 33 and from the start of the railroad crossing interruption to the arrival of the railroad crossing entrance. Time (time taken from the start of railroad crossing interruption to completion = train advance warning time due to railroad crossing ringing + time of descent of the rail can + standard value of alarm time 20 seconds, T ₄ = transmission time + idle time + T _p It has the characteristic that it is calculated as the sum of the larger one).

  In the present embodiment described above, the transmission of the railroad crossing blocking command can be delayed by the time for notifying the lowering of the barrier ring and the time required for the lowering of the barrier bar than in the case of the first embodiment. it can.

  Therefore, in the present embodiment, when the train 37 is at a high speed, the railroad crossing warning time can be made shorter than in the case of the first embodiment.

  In the present embodiment, when the crossing control device 33 is not operating and the operation control unit 39 does not receive an answer back, the train 37 stops before the crossing entrance. For this reason, safety can be improved compared to a level crossing control method that does not use an answer back.

  Further, in the present embodiment, even when the traveling control pattern is not set in advance, the time for shutting off the level crossing 32 can be shortened based on the traveling control algorithm.

(Third embodiment)
In the present embodiment, a modification of the first embodiment will be described.

  FIG. 12 is a block diagram illustrating an example of a railroad crossing system according to the present embodiment.

  In the present embodiment, the upper part 50 of the train 41 includes the data storage unit 9 and the operation control unit 42.

  The railroad crossing system according to the present embodiment is substantially the same as the railroad crossing system according to the first embodiment, but the track circuit transmission / reception unit 30 in FIG. 1 is not incorporated, and instead, a speed / position detection unit. 43 and the terminal device 6, and the terminal device 6 and the receiving unit 10 can exchange information wirelessly via the communication device 44.

  The logic unit 7 receives information such as the position of the train 41 from the interlocking device 27 and the terminal device 6, the route that is currently open, information such as the temporary speed limit from the operation management system 28, and the stop target position or approach for each train The possible distance is calculated, and this allowable distance is entered into the terminal device 6 together with the type of the prohibited entry area (the presence of the preceding train, the changeover of the turnout, the route is not opened, the level crossing is not blocked, etc.) provide.

  The terminal device 6 is connected to the logic unit 7 via a network such as a LAN 29, for example. The terminal device 6 receives the train position of each train from the speed / position detection unit 43 of each train via a communication device (communication means such as a coaxial leak cable) 44, and the train position of each train. Is provided to the logic unit 7. In addition, the terminal device 6 transmits the stop target position or the approachable distance for each train received from the logic unit 7 to the receiving unit 10 of each train via the communication device 44.

  The speed / position detection unit 43 provided in the operation control unit 42 calculates the speed and position of the train 41 based on a pulse signal from the speed generator 12 and the like. Further, the speed / position detection unit 43 corrects the position information of the train 41 based on the position correction information received from the position correction ground element reception unit 11. Furthermore, the speed / position detection unit 43 periodically transmits information such as the own train ID or the position of the own train to the terminal device 6 via the communication device 44.

  The receiving unit 10 receives the stop target position or the approachable distance calculated by the logic unit 7 via the terminal device 6 and the communication device 44.

  The stop pattern calculation unit 45 provided in the operation control unit 42 includes a stop target position or an approachable distance received by the receiving unit 10, gradient information read from the route information database 15, curve information, speed limit, and the like. Based on the information, information such as the deceleration performance of the train 41 read from the train performance database 14, information such as running resistance, and the information such as the position of the train 41 calculated by the speed / position detector 43, before the end of the opening section. A stop pattern for stopping the train 41 and a deceleration pattern for decelerating the train 41 to the speed limit before the speed limit section are calculated.

  The operation of the railroad crossing system according to the present embodiment is the same as the railroad crossing system according to the first embodiment, but instead of creating a stop pattern based on the on-line state of each train with respect to each track circuit, It differs greatly in that a stop pattern is created according to the position of the preceding train.

  FIG. 13 is a diagram illustrating an example of a state in which the presence of the preceding train is detected in the destination track circuit and the stop position in the stop pattern is determined for each track circuit.

  In FIG. 13, the stop position in the stop pattern does not move until the preceding train 46 passes through the destination track circuit. Therefore, the traveling of the control target train 47 is easily affected by the stop pattern, and the speed is likely to decrease. .

  On the other hand, FIG. 14 is a diagram illustrating an example of a state in which the position of the preceding train 46 is detected and the stop position in the stop pattern of the train 41 to be controlled is determined according to the position of the preceding train 46. In the present embodiment, control is performed according to the state shown in FIG.

  In FIG. 14, in order to stop the train 41 in the present embodiment in front of the preceding train 46 during normal traveling, the stop position in the stop pattern is not moved in units of track circuits, but the advance train 46 progresses. Move it finely in response.

  For this reason, in this embodiment, the same effect as the first embodiment can be obtained, and further, the time point when the train 41 is restricted by the stop pattern can be delayed, It can be made difficult to be restricted by the stop pattern.

(Fourth embodiment)
In the present embodiment, a modification of the second embodiment will be described.

  FIG. 15 is a block diagram illustrating an example of a railroad crossing system according to the present embodiment.

  In the present embodiment, the upper part 51 of the train 48 includes a data storage unit 9 and an operation control unit 49.

  The railroad crossing system according to the present embodiment is substantially the same as the railroad crossing system according to the third embodiment, but the answerback transmission unit in the railroad crossing control device 33 is the same as in the case of the second embodiment. The difference is that 35 is connected to the shut-off command receiver 34.

  In the present embodiment, the position information of each train is transmitted from the speed / position detection unit 43 of each train to the logic unit 7 via the communication device 44 and the terminal device 6 as in the third embodiment. The

  The logic unit 7 calculates stop target position information of each train based on the position information of each train. Then, the logic unit 7 transmits the stop target position information of each train to the receiving unit 10 of each train via the terminal device 6 and the communication device 44.

  The operation of the crossing system according to the present embodiment is substantially the same as that of the crossing system according to the second embodiment.

  However, in the present embodiment, as in the case of the third embodiment, in order to stop the control target train 48 before the preceding train during normal traveling, the stop position in the stop pattern is set in units of track circuits. Instead of moving the train, it is moved finely according to the progress of the preceding train.

  As a result, in this embodiment, transmission of the railroad crossing blocking command can be delayed by the amount of time for notifying the lowering of the barrier ring and the time required for the lowering of the barrier bar than in the case of the third embodiment. it can.

  Therefore, when the train 48 is traveling at a high speed, the level crossing alarm time can be shortened as compared with the level crossing system according to the third embodiment.

  Note that the present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage.
