Description

  The present invention relates to a train control device that transmits information from a ground train control device to control a train, and in particular, when a failure occurs in a track circuit, a train that prevents a train from colliding and allows train travel to be continued. The present invention relates to a control device.

Conventionally, as a technique for controlling the train speed in order to prevent a train collision, Patent Literature 1 gives a limit position (hereinafter referred to as stop target position information) at which the train can travel from the ground train control device. Set the speed protection pattern so that the train does not travel, compare the position and speed protection pattern of your own position, control the speed so that it does not exceed this, and realize the security by performing the speed control corresponding to your position Has been shown to do.
As a technique for controlling a train when a track circuit failure occurs, Patent Document 2 discloses that when a track circuit failure occurs between stations, the station is switched to one closed section, and only one train is included in the section. By making it possible to enter, it is possible to increase the train operating speed in this closed section and run the train. In Patent Document 3, when a track circuit failure occurs, the track circuit in which the failure has occurred The train crew visually confirms that the train is absent on the inner track circuit ahead of the track circuit when viewed from the direction of train travel, and informs the crew that the train is absent from the command. It is shown that the safety is realized by switching the fault track circuit and the inner track circuit of the fault track circuit to one closed section by operation.

However, in the technique disclosed in Patent Document 1, when a digital signal for train detection is destroyed due to the occurrence of a failure in the track circuit, and the validity of the digital signal cannot be confirmed by the ground train control device, the ground train control device uses this track. The circuit is judged to be faulty, and the stop target position information for the train that is outside the faulty track circuit in front of the train as viewed from the direction of travel of the train is set outside the track circuit that is determined to be faulty, and the track circuit fault is normal. Until it becomes, this stop target position information is forbidden to be inside the fault track circuit, so if it is unavoidable to enter the fault track circuit, the train driver will use the train control system of the on-board train controller Must be manually changed to a train control system that performs slow running while maintaining a low speed.
In addition, when returning to the normal track circuit after entering the track circuit fault location, the train driver will also return the train control system to the system before slow running. It is necessary to return the train control system of the control device to the normal train control system from the train control system that performs slow running manually.

Furthermore, when the train control system of the on-board train controller is a train control system that can be manually driven only by slow travel, the rear train can travel slowly even if the train is on the front, If it is assumed that the train driver neglects to visually check the forward train and the train stop is delayed, the possibility of collision with the forward train cannot be excluded.
In addition, if the technique of Patent Document 1 is applied to the techniques shown in Patent Document 2 and Patent Document 3, the digital signal for train control is destroyed in the track circuit failure section and cannot be normally received on the train side. Therefore, since entry into the track circuit failure section is prohibited, it is also necessary to manually switch the train control method to the train control method that performs slow running so that the track circuit failure section can also travel.
Furthermore, in the technique shown in Patent Document 3, when a track circuit failure occurs, the crew member visually confirms that the track circuit in which the failure has occurred and that the train is not on the inner track circuit, The crew member informs the command on the ground train controller side that the train is not present, and the operation from the command switches the fault track circuit and the inner track circuit of the fault track circuit to one closed section, but the crew member makes a mistake Or, if there is a communication error in the confirmation result, the possibility that train collision cannot be avoided cannot be excluded.

  Therefore, an object of the present invention is to provide an on-board train control device automatically in accordance with an instruction from the train control device without a train driver manually changing the train control system of the on-board train control device when a track circuit failure occurs. When changing the train control method and running on the track circuit fault zone, the train control method of the on-board train control device is set to slow travel, and train travel is possible even if the signal for train control cannot be received. And a train control device that permits slow travel only when there is no train in the section where slow travel is caused by a track circuit failure.

In order to solve the above-mentioned problems, the following technical means were taken in the train control device of the present invention. That is,
(1) In a train control device comprising: a ground train control device; and an on-board train control device that controls the own train by receiving the head track circuit and the stop target track circuit of the train from the ground train control device, The ground train control device includes a train track detection unit that detects a train track circuit based on a reception level of a train detection signal received from each track circuit, and a fault track circuit based on whether the train detection signal is valid. A fault track circuit detecting means for detecting, a means for transmitting the fault track circuit to a slow travel instruction device, a means for generating the stop target track circuit based on the train standing track circuit and the fault track circuit, and the slow train Means for transmitting the slow travel start track circuit and the slow travel release track circuit corresponding to the failed track circuit received from the travel instruction device to the on-vehicle train control device; The on-board train control device performs slow travel when all the three track circuits of the slow travel start track circuit, the stop target track circuit, and the head track circuit of the own train that are received from the ground train control device match. Means for switching to the mode, and means for canceling the slow running mode when the slow running release track circuit received from the ground train control device coincides with the head track circuit of the own train.

(2) In the train control device described above, the ground train control device is configured such that if there is no train on the track circuit and the track circuit inside the track, the track outside the track of the track A circuit as the stop target track circuit, and if a train is present in either the failed track circuit or the track circuit inside one track, the track circuit outside one track of the failed track circuit; The stop target track circuit generates information for determining that the on-board train control device is invalid, and further sets the stop track as the stop target track further than the track circuit outside one track of the failed track circuit. And means for forming a circuit.

(3) In the train control device, the slow travel instruction device receives the fault track circuit from the ground train control device, and determines an outer one track circuit of the fault track circuit as the slow travel start track circuit. And means for receiving the failed track circuit from the ground train controller and determining a track circuit inside one track of the failed track circuit as the slow running release track circuit.

(4) In the train control device described above, the ground train control device includes a control LAN, a slow travel transmission device, and a transmission unit including a slow travel start track circuit and a slow travel release track circuit received from the slow travel instruction device, Alternatively, a means for transmitting to the train is provided via the control LAN, the transceiver, and the transmission path.

(5) In the train control device described above, the on-board train control device includes means capable of communicating with a transmission means or means capable of communicating with a transmission path, and the slow running start trajectory received from the transmission means or the transmission path. A circuit and means for receiving the slow running release track circuit, and means for receiving the stop target track circuit transmitted from the ground train control device via a control LAN, a transceiver and a transmission path.

  According to the present invention, the ground train control device generates the stop target track circuit based on the train standing track circuit and the fault track circuit, and the stop target track circuit and the slow travel instruction device are determined based on the fault track circuit. The slow running start track circuit and the head track circuit of the own train are transmitted to the on-board train control device, and the on-board train control device automatically switches to slow running when these track circuits all match, Since the slow running cancellation track circuit transmitted by the ground train controller and the top track circuit of the own train in the stop position information match, the slow running can be automatically canceled, drastically reducing the maintenance burden. In addition, human error can be reliably prevented.

In addition, according to the above configuration, the train is on the track circuit where the failure has not been detected in the fault track circuit and the inner track circuit of the fault track circuit, and the head of the train is on the track circuit that starts slow running In this case, the stop train information in the stop position information transmitted from the ground train control device to the track circuit that starts slow running is used as information that is judged invalid by the on-board train control device, thereby starting slow drive. The train on the track circuit is not switched to slow travel, and a rear-end collision with the preceding train can be reliably avoided.
Furthermore, for trains that are outside the track circuit that starts slow running, the stop target stop track circuit that is transmitted by the ground train control device is connected to the track circuit that is one track outside the fault track circuit and further outward. By using the track circuit, it is possible to enter the slow running start track circuit and to reliably avoid a rear-end collision with the preceding train.

In addition, according to the above configuration, the section of the fault track circuit runs slowly on the condition that the preceding train is not present inside, and does not use the stop target track circuit transmitted by the ground train control device. Since the vehicle can travel, the vehicle can continue traveling even if the digital signal is destroyed in the section of the fault track circuit.
Thus, according to the present invention, the train detection is performed by the change in the reception level of the train detection signal, and the track circuit failure is detected by checking the validity of the digital signal for performing the train detection. Inner of track circuit failure 1 Train control device allows entry into track circuit failure section only when train is not on track circuit where failure is not detected in track circuit, avoiding train collision due to human error Can do.

  Furthermore, according to the present invention, when a track circuit failure occurs, the train control method of the on-board train control device can be automatically changed by an instruction from the ground train control device, and the train enters the track circuit failure section. Since the train control device confirms that there is no train on the track circuit failure section and permits slow travel, it is possible to avoid train collision during slow travel.

A digital signal transmitted to detect a train is received periodically via the transceiver 109 and the control LAN 106.

  The track circuit failure determination unit 203 analyzes information stored in a predetermined address such as, for example, an ID code assigned to each track circuit, among the digital signals received by the train detection signal reception unit 202. The validity of the digital signal is confirmed by checking whether or not it has been correctly received (step S301). If the validity cannot be confirmed, it is determined that the track circuit has failed and a failure has occurred. The track circuit is stored in the track circuit failure storage table 401 of the track circuit failure storage unit 204 (step S303).

  The track circuit fault transmission unit 205 transmits information on the track circuit in which a fault has occurred, which is stored in the track circuit fault storage table 401 of the track circuit fault storage unit 204, to the slow travel instruction device 104. The slow travel instruction device 104 that has received the information of the track circuit in which the failure has occurred uses the track circuit that starts slow travel as the slow start position information, and uses the track circuit that releases slow travel as the slow travel release position information. It transmits to the ground train control apparatus 105.

  The track circuit that starts slowing and the track circuit that cancels slowing are canceled by the slow traveling instruction device 104 based on the received failure track circuit information, and the slow running command device 104 automatically starts slow traveling and the slow circuit. The track circuit to be calculated is calculated, but a person who gives a command on the ground train control device side may check each time to determine these track circuits.

FIG. 5 shows a configuration example of the slow start position / slow release position storage unit 206.
In this example, as shown in the upper side of FIG. 1, when a train is in the track circuit AT and 2T and 3T are fault track circuits, a track circuit (1T) for starting slow travel, a track circuit for releasing slow travel ( 4T) is determined.

The position / slowing release position storage unit 206 stores the slowing start position / slowing release position storage table 501.
The slowing start instruction / slowing release instruction output unit 207 includes a track circuit (1T) for starting slowing, which is stored in the slowing start position / slowing release position storage table 501 of the slowing start position / slowing release position storage unit 206. It is generated as slow travel start instruction information, and is transmitted to the slow travel instruction receiving device 102 of the train 103 as the slow travel start instruction information 112 via the control LAN 106, the slow travel instruction transmission device 107, and the transmission means 108.
Further, the slowing start instruction / slowing cancellation instruction output unit 207 is a track circuit (4T) for canceling slowing, which is stored in the slowing start position / slowing release position storage table 501 of the slowing start position / slowing release position storage unit 206.

However, the slow travel start instruction information and the slow travel release instruction information can be transmitted to the slow travel instruction receiving device 102 of the train 103 via the control LAN 106, the transceiver 109, and the transmission path 110.

FIG. 6 is a flowchart for determining a train line by the train line position determination unit 208, and FIG. 7 shows a configuration example of the train line position storage unit 209.
The train existing line position storage unit 209 includes a train existing line position storage table 701, and stores a track circuit determined to be a train existing line.
The train position determination unit 208 generally uses the fact that when a train is present in the target track circuit, the rails are connected by the train wheels and axles, and the current to the transceiver is bypassed. When the reception level of the digital signal received by the train detection signal receiving unit 202 is equal to or lower than the train presence determination level (step S601), it is determined that the train is on the track circuit. 203, even if a failure occurs in which the validity of the digital signal received by the train detection signal receiving unit 202 cannot be confirmed, it is certain whether the train is present or absent depending on the reception level of the digital signal. Can be detected. Thus, the track circuit determined to be a tracked line stores the train tracked track circuit in the train tracked line position storage table 701 of the train tracked line position storage unit 209 (step S602). In the example of FIG. 7, a state is shown in which the train is not on the previous eight track circuits from the track (AT) where the train is currently on track.

FIG. 8 is a flowchart in which the stop target position information generation unit 210 creates stop target position information for each track circuit.
The stop target position information generation unit 210 acquires the fault track circuit information from the track circuit fault storage table 401 of the track circuit fault storage unit 204, and the train is connected from the train track position storage table 701 of the train track position storage unit 209. The track circuit information is acquired, and the train is not present in the failed track circuit (step S801), and the train is not present in the track circuit in which no failure is detected in the inner track of the failed track circuit (step S802). ) Is information indicating that the target stop position in the undetected track circuit in the outer track circuit of the failed track circuit is the outer track circuit of the failed track circuit (step S803), and the outside of the failed track circuit. Generate information (step S804) that sets the stop target position in the undetected track circuit in two tracks as the outer track circuit of the failed track circuit (step S804). The track circuit information where the head of the train that transmits the position information is added is added to the on-board train control device 101 of the train 103 from the stop target position information output unit 211 via the control LAN 106, the transceiver 109, and the transmission path 110. Send.

The upper side of FIG. 1 will be described as an example. When the track on which the train is currently located is AT (0T), the track circuit 1T is not detected, the track circuits 2T and 3T are fault track circuits, and the track circuit 2T. Since the preceding train is not present at 3T and 4T, the stop target position in the track circuit 1T is set to 1T, and the stop target position in the track circuit (-1T, -2T...) Outside the AT is also set to 1T.
On the other hand, the stop target position information generation unit 210 acquires the fault track circuit information from the track circuit fault storage table 401 of the track circuit fault storage unit 204 and trains from the train track position storage table 701 of the train track position storage unit 209. Is acquired, and when a train is present in the failed track circuit (step S801), or in the track circuit in which no failure is detected in the inner one track circuit of the failed track circuit, In the case of (Step S802), the stop target position in the undetected track circuit in the outer track circuit of the failed track circuit is determined to be invalid by the on-board train control device (Step S805), Information that sets the target stop position in the undetected track circuit on the two outer tracks of the circuit as the outer two track circuit of the failed track circuit (step S806) To generate.
Then, the track circuit information where the head of the train that transmits the stop target position information is located is added, and the on-board train of the train 103 is transmitted from the stop target position information output unit 211 via the control LAN 106, the transceiver 109, and the transmission path 110. Transmit to the control device 101.

  In the upper side of FIG. 1, the case where the preceding train is present in the track circuit 4T that is one track inward from the faulty track circuits 2T and 3T will be described as an example. The stop target position set as the circuit 1T is set as invalid information, and the track circuit (0T) outside one track is set as the stop target position.

The slow travel start track circuit storage unit 902 includes a slow travel start track circuit storage table 1001. In this example, the failure track circuits are only 2T and 3T, so 1T is used as a track circuit for starting slow travel. Remember.

The on-board train control device 101 includes a stop target track circuit storage unit 1201 and a speed protection pattern generation unit 1202, and FIG. 13 shows a configuration example of the stop target track circuit storage unit 1201.
The stop target track circuit storage unit 1201 includes a stop target track circuit storage table 1301, and stores the stop target track circuit in the stop target position information and the train head track circuit in the stop target position information. In this example, 1T is set as the stop target track circuit, and the train standing track position determination unit 208 shows a state in which the track circuit at the head of the train is 1T and the two match.

FIG. 14 shows a flowchart in which the speed protection pattern generation unit 1202 switches from the normal speed protection pattern to the slow running pattern.
The speed protection pattern generation unit 1202 of the on-board train control device 101 receives the stop target track circuit and the train head received from the transmission path 110 and stored in the stop target track circuit storage table 1301 of the stop target track circuit storage unit 1201. The track circuit that coincides with the track circuit (step S1401) and that is received from the slow travel start track circuit information output unit 903 and the track circuit that starts the slow travel, and the stop target of the stop target track circuit storage unit 1201 that is received from the transmission path 110 When the stop target track circuits stored in the track circuit storage table 1301 match (step S1402), the speed protection pattern is automatically switched from the normal speed protection pattern to the slow running pattern (step S1403).
Further, the speed protection pattern generation unit 1202 of the on-board train control device 101 receives the stop target track circuit received from the transmission path 110 and stored in the stop target track circuit storage table 1301 of the stop target track circuit storage unit 1201. The train head track circuit does not match (step S1401), or the slow track start track circuit information output unit 903 received from the slow track start track circuit and the transmission path 110, and the stop target track circuit storage unit 1201 When the stop target track circuit stored in the stop target track circuit storage table 1301 does not match (step S1402), the speed protection pattern remains the normal speed protection pattern (step S1404).

FIG. 15 is a flowchart in which the speed protection pattern generation unit 1202 switches from the slow running pattern to the normal speed protection pattern.
The speed protection pattern generation unit 1202 of the on-board train control device 101 receives the slow circuit release track circuit information output unit 906 from the slow travel release track circuit information output unit 906, and receives from the transmission path 110 the stop target track circuit storage unit. When the train head track circuit stored in the stop target track circuit storage table 1301 of 1201 matches (step S1501), the speed protection pattern is automatically switched from the slow running pattern to the normal speed protection pattern (step S1502).
Further, the speed protection pattern generation unit 1202 of the on-board train control device 101 receives from the slow travel cancellation track circuit information output unit 906, the track circuit that cancels slow travel, and the transmission target 110, and receives the stop target track circuit. If the train head track circuit stored in the stop target track circuit storage table 1301 of the storage unit 1201 does not match (step S1501), the speed protection pattern remains the slow travel pattern (step S1503).

According to the present invention, the on-board train control device 101 automatically switches to the slow running mode in the outer track circuit of the failed track circuit, and automatically switches to the normal speed protection pattern in the inner track circuit of the failed track circuit. Train control is possible.
Further, while the train is on the fault track circuit, the ground train control device 105 does not use the stop target position information to be transmitted to the train on the outside of the fault track circuit as a track circuit that switches to slow travel. By making the outer one track circuit of the track circuit to be switched to slow running and preventing the train from entering the track circuit failure section, it is possible to ensure safety so that the train does not collide.

This will be described with reference to FIG. 1. When a preceding train is present on the track circuit 3T, the track circuit outside the failed track circuits 2T and 3T is set as the stop target position.
Further, while the preceding train is present in the fault track circuit, the ground train control device 105 stores the stop target position information to be transmitted to the train existing outside the fault track circuits 2T and 3T, and the slow running start track circuit memory. This is not the track circuit for starting slow running stored in the slow running start track circuit storage table 1001 of the part 902, but is the outer one track circuit of the track circuit to switch to slow running from here, Even when the vehicle enters the track circuit that switches to slow travel, the ground train control device 105 recognizes that the stop target track circuit of the stop target position information transmitted to the track circuit that switches to slow travel is invalid in the on-board train control device 101. By transmitting information to prevent the train from automatically switching to slow running mode, the train cannot enter the fault track circuit, and the train does not collide It is possible to ensure the sea urchin safety.
That is, in the example of FIG. 1, when the preceding train is on the track circuit 3T, the stop target position of the track circuit 1T is information recognized as invalid by the on-board train control device.

  In the above embodiment, the case where a digital train control device that performs information transmission using a track circuit that uses a railroad rail as a transmission path is employed as the train control device has been described. When applied to a device that controls a train using digital signals (ATC, ATS, ATO, train control device using a loop coil, etc. of multistage brake control), the same effect can be obtained.

  As described above, according to the present invention, the ground train control device generates the stop target track circuit based on the train standing track circuit and the fault track circuit, and the stop target track circuit and the slow travel instruction device include the fault track. The slow running start track circuit determined based on the circuit and the head track circuit of the own train are transmitted to the on-board train control device, and the on-board train control device automatically makes a slow drive by matching all these track circuits. The slow train release track circuit sent by the ground train controller and the top track circuit of the own train in the stop position information match, so that the vehicle can automatically run slowly without adding special equipment. Since it can be released, it can be expected to be widely adopted as a train control device that drastically reduces the maintenance burden and reliably prevents human error.
