Description

  The present invention relates to a train control device, a linkage device, and a train control method for reducing facility costs and maintenance costs in a single track section using general-purpose telephone wireless communication and for ensuring safe operation of a train.

  In order to safely control the operation of the train, a current position of the train is detected using a track circuit as shown in Patent Document 1, or a GPS provided with a radio wave from a GPS satellite as shown in Patent Document 2 The signal is acquired by the receiver and the current position of the train is detected, and on the premise of this rapid train position detection, the signal device and the switch are controlled by the interlocking device.

  In this train control, the course setting and securing by the interlocking device is the basis of safety, and for this reason, the interlocking station equipment with the branching device that is switched by the toppling machine, the interlocking device that controls the traffic light, the turning machine, etc. The communication with the on-board device mounted on the train needs to have no transmission delay and ensure continuity. Therefore, as shown in Patent Document 1, Patent Document 3, etc., the communication quality is high. A dedicated communication line is used.

  It quickly detects when the train is in the closed section, and quickly locks the relevant turnouts and routes by transmitting train control signals using a dedicated communication line. Because it is necessary to stop the train, the transmission of the train control signal using the dedicated communication line is premised on constant communication, and is controlled to the safe side in the event of a communication failure.

  In addition, in transmission using a dedicated communication line, train section advancement is quickly detected, and related branching devices and routes are promptly unlocked by transmission of train control signals using a dedicated communication line. Because it is necessary to realize high-tracking and high-density operation with rapid follow-up, train control signal transmission using a dedicated communication line is premised on continuous transmission, and when train control signal transmission stops, the train is stopped and controlled. ing.

  The dedicated communication lines that have been used so far have cables laid vertically and horizontally in accordance with the devices arranged along the railway along the alignment. Since this dedicated communication line is responsible for safety-related communications, daily inspection and maintenance and maintenance are required for safe and stable operation of the train. This daily maintenance inspection and maintenance is becoming a burden for railway operators in single-track operation sections where the number of operating trains is relatively small.

  In addition, it is possible to use a general-purpose telephone radio line such as a mobile phone radio network instead of a dedicated communication line, but the general-purpose telephone radio line requires time for dial-in, and it is not completely guaranteed that it can communicate even as a constant connection, Communication continuity and immediacy are impaired. Traditionally, the lock of the switch that switches the branching unit and the lock of the train route are based on the necessity of detecting the presence of a train on the premise of the immediacy of the presence of the train. In addition, a general-purpose telephone wireless line such as a mobile telephone wireless network that assumes communication delay is not applicable to route setting and securing by an interlocking device that assumes immediacy.

  The present invention eliminates such problems, eliminates the need for communication cable equipment costs and maintenance costs in single-line operation sections where the number of operating trains is relatively small, and ensures reliable closure in any case. The purpose of the present invention is to provide a train control device, an interlocking device, and a train control method capable of improving the safety of the train.

  The on-board device has two GPS receivers connected to two GPS antennas provided at the front and rear ends of a train, and the position signal input from the two GPS receivers 2 When calculating the distance between the two GPS antennas, comparing the calculated distance with the preset installation interval of the two GPS antennas, if the calculated distance matches or approximates the installation interval, When the position input from the two GPS receivers is the train position and the calculated distance does not approximate the installation interval continues for a certain period of time, the train position is corrected by the signal from the speed generator It is characterized by that.

Interlock device of this invention is a performing interlock the automatic route setting function of chain functions and trains between mutual traffic and point lock device of the interlocking station facility, the point lock device of the interlocking station facility It is always locked, and the train position and train speed transmitted from the train and the turning direction of the turning machine transmitted from the interlocking station facility are input, and the unlocking machine is always unlocked. If there is a need to change the train, make sure that the train that is not on the train line in the survey section and the train in the adjacent section outside the study section is stopped. Unlock and switch the machine, lock it again after the switching operation of the switch machine is completed, lock the relevant opposite path and the competing path, lock the train travel path, and The train travel route that is set and locked is transmitted to the on-board device to allow the train to travel. Road is characterized in that impossible unlocking unless sure the on-board signal on the corresponding train stop the vehicle device becomes stopped current-.

This ensures the safe setting of the traveling route and the traveling safety of the train 1.

  The on-board device 2 includes two GPS receivers 5a and 5b, a communication device 6, a central processing unit 7, and a speed control unit 8, as shown in the block diagram of FIG. The GPS receivers 5a and 5b receive radio waves transmitted from the GPS satellites 10 through GPS antennas 9a and 9b provided at the front and rear ends of the train 1, respectively, and measure the position (latitude / longitude) of the train.

The calculated distance Lx and the position input from the GPS receiver 5a are output to the position correction unit 18. The distance integrating unit 16 integrates the distance traveled by the train 1 based on a signal input from the speed generator 20. The control information storage unit 17 stores in advance various information such as the installation interval L of the GPS antennas 9a and 9b, train-specific information, route information on which the train 1 travels, and speed limit information. The position correction unit 18 compares the distance Lx between the GPS antennas 9a and 9b input from the GPS position detection unit 15 with the installation interval L of the GPS antennas 9a and 9b stored in the control information storage unit 17, and detects the GPS position. When the distance Lx calculated by the unit 15 matches or approximates the installation interval L of the GPS antennas 9a and 9b, it is determined that the two GPS receivers 5a and 5b are operating normally, and the GPS receiver The positions input from 5a and 5b are output to the arithmetic processing unit 19. When the distance Lx calculated by the GPS position detection unit 15 is not approximate to the installation interval L of the GPS antennas 9a and 9b, the position correction unit 18 is either one or both of the two GPS receivers 5a and 5b. And calculating the position of the train 1 based on the distance traveled by the train 1 input from the distance integrating unit 16 and the route information traveled by the train 1 stored in the control information storage unit 17 The data is output to the processing unit 19. The arithmetic processing unit 19 creates a speed pattern from the position of the train 1 input from the position correction unit 18, the speed control information stored in the control information storage unit 17 and the information input from the communication device 6, and outputs the speed pattern to the speed control unit 8. Then, the speed of the train 1 is controlled. In addition, the arithmetic processing unit 19 outputs train state information indicating the position of the train 1 input from the position correction unit 18 and whether the train 1 is running or stopped together with the train specific information to the communication device 6. The communication device 6 transmits train status information and the like to the general-purpose telephone radio line 14 when it is within the communication area of the base station 13 of the general-purpose telephone radio line 14.

  As shown in the block diagram of FIG. 3, the center device 3 includes a communication device 21 and a centralized interlocking device 22. The communication device 21 exchanges information with the base station 13h provided in the general-purpose telephone wireless line 14 through the communication antenna 23 by mobile phone communication. The central interlocking device 22 exchanges various information with the on-board device 2 and the interlocking station facility 4 and performs a chain function and an automatic route setting function between the traffic lights of the interlocking station facility 4 and a switch.

  As shown in the block diagram of FIG. 4, the interlocking station facility 4 includes a communication device 24, an electronic terminal device 25, a switch 26 and a switch 27. The communication device 24 exchanges various information through mobile phone communication with a base station 13e (13g) including communication stations 29a and 29b of the general-purpose telephone wireless line 14 in a communication area via a communication antenna 28. The electronic terminal device 25 controls the operation of the turning machine 26 based on the information input from the communication device 24, displays the state of the turning machine 26 on the turning display 27, and the state of the turning machine 26. Are transmitted to the general-purpose telephone wireless line 14 via the communication device 24.

  Processing when detecting the position of the train 1 and whether or not it is stopped by this train control device will be described.

  The GPS receiver 5a outputs a position signal to the GPS position detector 15 by a signal output from the GPS antenna 9a installed at the front of the train 1, and the GPS receiver 5b is received from the GPS antenna 9b installed at the rear of the train 1. The position signal is output to the GPS position detector 15 by the output signal. The GPS position detector 15 calculates a distance Lx between the GPS antennas 9a and 9b provided at the front and rear ends of the train 1 based on the position signal input from the GPS receiver 5a and the position signal input from the GPS receiver 5b. The calculated distance Lx and the position input from the GPS receivers 5 a and 5 b are output to the position correction unit 18. The position correction unit 18 compares the distance Lx between the GPS antennas 9a and 9b input from the GPS position detection unit 15 with the installation interval L of the GPS antennas 9a and 9b stored in the control information storage unit 17, and detects the GPS position. When the distance Lx calculated by the unit 15 matches or approximates the installation interval L of the GPS antennas 9a and 9b, it is determined that the two GPS receivers 5a and 5b are operating normally, and the GPS receiver The positions input from 5a and 5b are output to the arithmetic processing unit 19. When the distance Lx calculated by the GPS position detection unit 15 does not approximate the installation interval L of the GPS antennas 9a and 9b continues for a certain period of time, the position correction unit 18 has two GPS receivers 5a. , 5b, it is determined that an abnormality has occurred in either one or both, and the train is input based on the distance traveled by the train 1 input from the distance integrating unit 16 and the route information traveled by the train 1 stored in the control information storage unit 17. 1 position is calculated and output to the arithmetic processing unit 19.

  Thus, the distance Lx calculated based on the position signal output from the GPS receiver 5a and the position signal output from the GPS receiver 5b is compared with the installation interval L between the GPS antennas 9a and 9b installed before and after the train 1. Therefore, it is possible to reliably detect the presence / absence of abnormality of the GPS receivers 5a and 5b. Further, when the GPS receivers 5a and 5b are abnormal, the position of the train 1 is corrected by the signal from the speed generator 20, so that the position of the train 1 can be detected reliably.

  In this state, the arithmetic processing unit 19 detects the speed of the train 1 based on the signal input from the speed generator 20, and determines whether the train 1 is running or stopped at the position input from the position correction unit 18 based on the detected speed. Determine and output to the communication device 6. When the communication device 6 is in the communication area of the base station 13 of the general-purpose telephone wireless line 14, it transmits the train-specific information and information indicating the train position and whether the vehicle is running or stopped by mobile phone communication. When the central interlocking device 22 of the center device 3 inputs the information transmitted from the train 1 via the communication device 21 from the general-purpose telephone wireless line 14, whether or not it is traveling with the existing line position of each train 1 according to the input information. Make sure that

  The central interlocking device 22 of the center device 3 normally provides a control signal for switching the turning machine 26 that branches the upper and lower main lines in the inspection section of the interlocking station facility 4 in the single-track operation section, that is, in the section with the branching device. The data is transmitted from the communication device 21 to the general-purpose telephone wireless line 14 via the communication antenna 23 to the interlocking station facility 4 by mobile phone communication. When the communication device 24 of the interlocking station facility 4 receives the control signal for switching the switch 26 from the general-purpose telephone wireless line 14 by mobile phone communication, it outputs the received control signal to the electronic terminal device 25. When the electronic terminal device 25 receives a control signal for switching the switch 26, the switch 26 is switched. When the switch 26 is completely converted, the switch 26 is locked. Is displayed on the display 27 and transmitted from the communication device 24 to the center device 3 via the general-purpose telephone wireless line 14. The central interlocking device 22 of the center device 3 can change the course of the interlocking station facility 4 when the switch 26 of the interlocking station facility 4 is converted from the general-purpose telephone wireless line 14 via the communication device 21 and a locked signal is input. Determine.

  In this state, when the central interlocking device 22 needs to unlock the locked switch 26 of the interlocking station equipment 4, it is connected from the onboard devices 2 of all the trains 1 via the general-purpose telephone radio line 14. All trains 1 are grasped based on the received information, and trains 1 are not surely located in the examination section, and all trains 1 are located in the approaching section at a fixed distance outside the examination section. After confirming that it has stopped reliably, the turning machine 26 of the interlocking station equipment 4 is unlocked and the turning machine 26 is changed.

  In conventional switch control, the outside fixed distance on the train approach side of the inspection section is set as the approach section, and the train 1 does not exist in this section, or the time required for braking the train 1 in the case of the existing line When the train enters the inspection section during the time including the allowance time, and the train 26 enters the inspection section during that time, the switch 26 is quickly locked according to the train line condition. In other words, in the conventional control of the turning machine, it is assumed that a high-speed train enters the unlocking section during unlocking, and even in that case, it is necessary to perform reliable locking as a quick locking It is a cause that does not allow communication delay, and requires continuity and immediacy of communication.

  On the other hand, when communication is performed on the premise of communication delay between the center device 3 and the train 1 by mobile phone communication using the general-purpose wireless communication line 14 as in the train control device of the present application, it is not possible to quickly detect on-line. , Grasp the state of all the trains 1, confirm that the train 1 is not present in the inspection section, and that the train 1 is stopped by the brake operation in the adjacent section, and unlock the switch 26 To convert.

  The central interlocking device 22 locks the traveling path of the train 1 by locking the opposite path and the competing path related to the completion of the switching operation of the switch 26 of the interlocking station equipment 4 and then locking again. The route is transmitted from the general-purpose wireless communication line 14 to the on-board device 2 of the train 1 to allow the train 1 to proceed. Once the road is locked, the corresponding train 1 is stopped and the on-board signal is not stopped. As far as unlocking is impossible.

  In this way, all trains 1 are grasped by the centralized interlocking device 22 and can be safely unlocked on the condition that all the trains 1 approaching the section in the locked state are surely stopped. Even when a general-purpose wireless communication line 14 that is not used is used, the safety can be reliably ensured by unlocking when the train stop can be communicated.

  The same applies to the path lock. In this case, since it is an absolute condition that the train 1 is not present in the route protection section during the route unlocking time, it is necessary to stop all the trains 1 that are present in the approach section of the fixed distance outside the route start end. Use unlocking conditions. Also in this case, all the trains 1 are grasped and it is confirmed that the train 1 is not surely present in the route protection section.

  A series of processes for controlling the operation of the switch 26 of the interlocking station facility 4 and the train 1 by the center device 3 of the train control device will be described.

  The central interlocking device 22 of the center device 3 always locks the switch 26 of the interlocking station facility 4. When it is necessary to change the constantly-switched turning machine 26 in the course setting, the central interlocking device 22 assumes that all trains 1 are grasped and the train absence line of the corresponding inspection section and the section Check whether there is a train on the outside approaching section. When the train 1 is present in the approaching section, the concentrated interlocking device 22 requests the traveling speed of the train 1 existing in the approaching section. When the central interlocking device 22 receives a reply of the traveling speed of 0 km / h from the onboard device 2 of the train 1 that is in the approaching section, the central interlocking device 22 requests the train 1 to perform stop control. Upon receiving the request for stop control, the on-board device 2 of the train 1 prevents the rolling of the train 1 and transmits the rolling prevention to the centralized interlocking device 22. When the central interlocking device 22 receives rolling prevention from the train 1, the central interlocking device 22 unlocks the corresponding switch 26 of the interlocking station facility 4 and converts it. The central interlocking device 22 sets the course of the train 1 by locking the switch 26 again when the switch display by the end of conversion of the switch 26 transmitted from the interlocking station facility 4 is input.

  When canceling the route once set, if train 1 is not in the route protection section and train 1 is not in the approaching section of the route, immediately if train 1 is in the approaching section The central interlocking device 22 confirms that the train 1 is stopped and stopped by the same processing as the unlocking of the inspection section, and the rolling machine 26 is unlocked. To open the course. When the route is opened, the central interlocking device 22 transmits the communication device 21 to the train 1 via the general-purpose telephone radio circuit 14. The arithmetic processing unit 19 of the on-board device 2 of the train 1 inputs the route opening from the communication device 6 and stores the in-vehicle signal as a progress indication and stores the stored progress indication from the communication device 6 via the general-purpose telephone radio circuit 14. To the center device 3. When the central interlocking device 22 receives a reply of the signal display from the onboard device 2 of the train 1, it recognizes that the onboard device 2 has stored the progress display. The on-board device 2 displays the progress indication and then holds the progress indication up to the course arrival point.

  In the above description, the position of the train 1 is determined by the GPS receiver 5a. Although the case where the position signal output from 5b is detected has been described, the train position detecting means is provided at a predetermined position on the ground, the position of the train 1 is detected by the train position detecting means, and the general-purpose telephone wireless line 14 is transmitted by mobile phone communication.
