Description

[Technical field]

[0001] The present invention relates to an operation resumption determination device that determines whether operation can be resumed from the stopping position of a moving body that has stopped when an earthquake occurs, and an operation resumption support system that supports early resumption of operation from the stopping position of a moving body that has stopped when an earthquake occurs. [Background technology]

[0002] When an earthquake occurs and the conditions for stopping operations are met, the earthquake early warning system immediately brings running trains to an emergency stop. After that, if the seismic motion observed by seismometers installed at regular intervals along the railway line by the railway operator exceeds a predetermined standard value, operation restrictions such as slowing down and inspections are implemented. A conventional earthquake early detection and warning system includes sensors that detect seismic motion at multiple detection points, and a control processing device that estimates the damage area based on the seismic motion information detected by each sensor and issues a warning as necessary (see, for example, Patent Document 1). This conventional earthquake early detection and warning system determines whether or not the earthquake is harmful based on the seismic motion information, and when it is determined that the earthquake is harmful, it stops the supply of power to the train and stops the operation of the train.

[0003] The Damage Information System for Earthquake on Railway (DISER) (registered trademark) has been developed with the aim of providing information to assist in the early resumption of train operations, and can obtain area-wide seismic motion distribution, detailed estimated information on seismic motion along registered lines, and estimated damage rank information for railway structures after an earthquake occurs. This railway earthquake damage estimation information distribution system estimates area-wide seismic motion distribution using public earthquake information made public immediately after an earthquake occurs and a ground database, estimates seismic motion along the tracks and the damage rank of structures due to this seismic motion, and distributes the estimated information to railway operators in real time (for example, see Non-Patent Document 1). This railway earthquake damage estimation information distribution system quickly resumes train operations based on the estimated information. [Prior art documents] [Patent documents]

[0006] When a large earthquake is detected by seismometers along railway lines, and the observed seismic motion exceeds a pre-defined threshold, trains in operation are immediately brought to an emergency stop and other operational restrictions are imposed. After that, staff visually inspect the condition of railway facilities such as structures along the line, and train operations are resumed only after safety is confirmed. However, since the inspection is done by humans on foot, it takes a long time, and train operations cannot be resumed until all inspections are completed and safety is confirmed. As a result, it takes a long time to stop trains between stations and rescue passengers, which is one of the factors that makes it difficult to resume operations quickly.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0017] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. The track R shown in FIG. 2 is a passage (track) on which trains T1 to T4 run. The track R is a double track consisting of two main lines, and is made up of a down track R1 on which down trains T1 and T3 run from the starting point to the end point, and an up track R2 on which up trains T2 and T3 run from the end point to the starting point. The trains T1 to T4 are moving bodies that move along the track R. The trains T1 to T4 are Shinkansen trains that run on Shinkansen (registered trademark) or conventional trains that run on conventional lines. The trains T1 to T4 are, for example, railway vehicles such as electric cars or internal combustion cars (internal combustion railcars), and are made up and organized of one or more railway cars.

[0018] The operation resumption support system 1 shown in Fig. 1 and Fig. 2 is a system that supports early resumption of operation from the stopping positions P1, P2, P4 of trains T1, T2, T4 that stopped during an earthquake. The operation resumption support system 1 evaluates the areal seismic motion distribution and the linear seismic motion distribution along the track R on which trains T1 to T4 run, based on observed seismic motion information observed immediately after an earthquake, and calculates the stopping positions P1, P2, P4 of trains T1, T2, T4 that stopped during an earthquake and the line-side seismic motion G DBased on this, it is determined whether or not early operation can be resumed from the stopping positions P1, P2, P4 of trains T1, T2, T4. The operation resumption support system 1 is, for example, a system for supporting early elimination of trains stopped between stations after an earthquake, in order to quickly eliminate trains stopped between stations during an earthquake. The operation resumption support system 1 includes an earthquake disaster prevention system 2 shown in Figs. 1 and 2, an earthquake observation system 3, a high-density earthquake observation system 4, a lineside earthquake motion evaluation system 5, a traffic control system 6, a communication network 7 shown in Fig. 2, an operation resumption determination device 8 shown in Figs. 1 and 2, an operation information display device 10 shown in Fig. 2, and an operation resumption notification device 11.

[0019] The earthquake disaster prevention system 2 shown in Fig. 1 and Fig. 2 is a system for measuring earthquake motions at each observation point using a seismometer M shown in Fig. 3. A ~M C The earthquake disaster prevention system 2 is an early earthquake warning system that estimates earthquake characteristics and performs operation restrictions based on initial tremor data of a few seconds of earthquake motion, for example. The earthquake disaster prevention system 2 includes early warning seismometers that are installed at each observation point and measure and record earthquake motion, a relay server that relays earthquake motion information between each seismometer and transmits and manages the earthquake motion information, and a monitoring terminal that monitors each seismometer and the relay server. The earthquake disaster prevention system 2 observes relatively sparse earthquake motions, for example, using seismometers installed at observation points along the railway line by railway operators. The earthquake disaster prevention system 2 can also use observed earthquake motion information output by the earthquake observation system 3, for example. The earthquake disaster prevention system 2 measures earthquake motions at each observation point as shown in Figs. 3(B) and (C) using the seismometer M. A ~M C Observed earthquake motion G A ~GC The earthquake disaster prevention system 2 detects the earthquake as the seismometer M A ~M C Observed earthquake motion G A ~G C The result is output as observed seismic motion information to the railway line seismic motion evaluation system 5 and the operation resumption determination device 8.

[0020] The earthquake disaster prevention system 2 shown in Fig. 1 and Fig. 2 judges whether or not to perform an emergency stop of trains T1 to T4 running on a track R when an earthquake occurs. A ,G B When the trains T1, T2, and T4 are traveling in the stop section S1 where the observed seismic motion G exceeds the stop reference value Th1, it is determined that the trains T1, T2, and T4 traveling in the stop section S1 need to be brought to an emergency stop. C When train T3 is traveling outside the stop section S1 where the earthquake velocity falls below the stop reference value Th1, it is determined that there is no need to make an emergency stop of train T3 traveling outside the stop section S1. Here, the stop reference value Th1 shown in FIG. 3(B) is a reference value when determining whether or not it is necessary to stop trains T1 to T4 after an earthquake occurs. The stop section S1 shown in FIG. 3(B)(C) is a section where trains T1, T2, and T4 must be stopped after an earthquake occurs. The boundary AB is located between the seismometer M A The sections covered by each company and seismometer M B The boundary BC is the boundary between the section that is shared by the seismometer M B The sections covered by each company and seismometer M C When an earthquake occurs and it is necessary to bring the trains T1 to T4 to an emergency stop, the earthquake disaster prevention system 2 automatically stops the power supplied to the trains T1 to T4 to activate the emergency brakes of the trains T1 to T4, and issues an emergency stop command to the drivers of the trains T1 to T4 via the train radio.

[0021] The earthquake observation system 3 is a system that uses the company's own seismometer M such as the earthquake disaster prevention system 2. A ~M CUnlike seismic motion observations by public facilities, seismic motion is observed by seismometers installed at each observation point by external public institutions such as the Japan Meteorological Agency or the National Research and Development Agency, the National Research and Development Agency for Earth Science and Disaster Resilience. The earthquake observation system 3 uses, for example, seismic motion information (emergency earthquake warnings) from the seismometers at each observation point of the Japan Meteorological Agency, or seismic motion information (K-NET observation data) from the strong earthquake observation network (Kyoshin Network (K-NET)) of the National Research and Development Agency for Earth Science and Disaster Resilience. The earthquake observation system 3 outputs the observed seismic motion observed by the seismometers at each observation point to the railway line seismic motion evaluation system 5 as observed seismic motion information (seismic motion information).

[0022] The high-density earthquake observation system 4 is a system for observing seismic motion along railway lines at high density. The high-density earthquake observation system 4 observes seismic motion along railway lines at high density by distributed acoustic sensing (DAS) that measures distributed strain using, for example, optical fiber cables as sensors. The high-density earthquake observation system 4 can use, for example, existing optical fiber cables for communication, and continuously measures seismic motion along railway lines at high density using optical fiber cables and distributed sound meters. The high-density earthquake observation system 4 includes an optical signal transceiver that pulses an optical signal and transmits it continuously from one end of the optical fiber cable, and receives a reflected signal (backscattered wave (Rayleigh scattered wave)) reflected from a small amount of impurities in the optical fiber cable, and an analysis unit that analyzes the reflected signal received by the optical signal transceiver. The high-density earthquake observation system 4 compares a reflected signal received when the length of the optical fiber cable changes during an earthquake with a reflected signal received during normal times, and observes seismic motion by detecting strain (deformation) of the optical fiber cable. The high-density earthquake observation system 4 uses tens of kilometers of optical fiber cable to measure strain every few meters, and can achieve extremely high-density observation at low cost compared to observation using conventional seismometers. The high-density earthquake observation system 4 outputs the high-density observed seismic motion observed along the railway line to the railway line earthquake motion evaluation system 5 as observed seismic motion information.

[0023] The lineside earthquake motion evaluation system 5 shown in Figs. 1 and 2 is a system for evaluating earthquake motion along a line. The lineside earthquake motion evaluation system 5 evaluates earthquake motion along a line based on observed earthquake motion information output by the earthquake disaster prevention system 2 and the earthquake observation system 3. As shown in Fig. 1, the lineside earthquake motion evaluation system 5 estimates earthquake motion along the line R based on observed earthquake motion information at each observation point output by the earthquake observation system 3, and estimates earthquake motion along the line R based on observed earthquake motion information at each observation point output by the earthquake disaster prevention system 2 and the earthquake observation system 3. The lineside earthquake motion evaluation system 5 estimates areal earthquake motion distribution and linear earthquake motion distribution along the line based on observed earthquake motion information immediately after an earthquake and ground information along the line, taking into account changes in ground characteristics when a strong earthquake motion acts. The railway line earthquake motion evaluation system 5 estimates the input earthquake motion of the foundation taking into account the amplification characteristics of the ground based on the observed earthquake motion information of each observation point, and performs spatial interpolation using the estimated input earthquake motion of the foundation to calculate the areal earthquake motion distribution of 500m mesh on the foundation. Here, spatial interpolation is a method used to predict surrounding data using known data such as observed values. The railway line earthquake motion evaluation system 5 calculates the areal earthquake motion distribution of the ground surface and the linear earthquake motion distribution along the railway line using the ground amplification characteristics of each mesh. The railway line earthquake motion evaluation system 5 is a railway earthquake damage estimation information distribution system that estimates the earthquake motion along the railway line and the damage rank of railway structures immediately after an earthquake, for example, to support appropriate judgment of the inspection range after an earthquake.

[0024] The lineside earthquake motion evaluation system 5 evaluates earthquake motion along the line based on observed earthquake motion information on high-density earthquake motion along the line observed by distributed acoustic measurement, for example. As shown in Fig. 1, the lineside earthquake motion evaluation system 5 evaluates earthquake motion along the line R based on observed earthquake motion information output by a high-density earthquake observation system 4. Unlike a method that estimates earthquake motion distribution along the line by spatially interpolating observed earthquake motion information output only by the earthquake observation system 3 or observed earthquake motion information output by the earthquake disaster prevention system 2 and the earthquake observation system 3, the lineside earthquake motion evaluation system 5 generates earthquake motion distribution along the line from observed earthquake motion information output by the high-density earthquake observation system 4.

[0025] The railway line earthquake motion evaluation system 5 estimates the railway line earthquake motion G from the areal earthquake motion distribution and the linear earthquake motion distribution estimated based on the observed earthquake motion information output by the earthquake disaster prevention system 2 and / or the earthquake observation system 3. D The seismic motion along the railway line G as shown in Fig. 1(A) and Fig. 3 was calculated. D The railway line earthquake motion evaluation system 5 generates railway line earthquake motion G based on the observed earthquake motion information output by the high-density earthquake observation system 4. D The seismic motion along the railway line G as shown in Fig. 1(B) and Fig. 3 was calculated. D The line seismic motion evaluation system 5 generates line seismic motion information that corresponds the line seismic motion G along the down line R1 and the up line R2 based on the observed seismic motion observed by the earthquake observation system 3, as shown in FIG. 3, for example. D As shown in Fig. 1(C) and Fig. 3(B), the railway line earthquake motion evaluation system 5 estimates railway line earthquake motion G according to the distance in kilometers when the vertical axis is earthquake motion and the horizontal axis is kilometers. D The railway line earthquake motion evaluation system 5 generates a waveform that represents the railway line earthquake motion G D The seismic motion information along the line (estimated seismic motion information) in which the distance and kilometre are associated with each other is output to the operation resumption determination device 8.

[0026] The traffic control system 6 shown in FIG. 1 and FIG. 2 is a system that manages the operation of the trains T1 to T4. The traffic control system 6 is a system that supports operations for smoothly advancing the operation of the trains T1 to T4. The traffic control system 6 is, for example, a train traffic control system (Programmed Traffic Control (PTC)) that centrally manages and controls the trains T1 to T4 based on a train schedule in railway train traffic control. For example, as shown in FIG. 3(A), the traffic control system 6 detects the stop position P1 of the train T1 that stopped on the down line R1 when an earthquake occurred, and detects the stop positions P2 and P4 of the trains T2 and T4 that stopped on the up line R2 when an earthquake occurred. The traffic control system 6 constantly grasps the operation status of the trains T1 to T4, detects the running position P3 and the stop positions P1, P2, and P4 of the trains T1 to T4 on the track R, and outputs the current positions of the trains T1 to T4 as position information (on-track position information) to the operation resumption determination device 8 and the operation information display device 10.

[0027] The communication network 7 shown in Fig. 2 is a network for transmitting and receiving various information related to the operation resumption support system 1. The communication network 7 transmits observed seismic motion information from the earthquake disaster prevention system 2 to the lineside seismic motion evaluation system 5 and the operation resumption determination device 8, transmits observed seismic motion information from the earthquake observation system 3 to the lineside seismic motion evaluation system 5, transmits observed seismic motion information from the high-density earthquake observation system 4 to the lineside seismic motion evaluation system 5, transmits lineside seismic motion information from the lineside seismic motion evaluation system 5 to the operation resumption determination device 8, transmits position information from the traffic control system 6 to the operation resumption determination device 8 and the operation information display device 10, and transmits operation resumption information from the operation resumption determination device 8 to the operation resumption notification device 11. The communication network 7 is an electric communication line (communication device) such as a telephone line or an Internet line that connects the earthquake disaster prevention system 2, the earthquake observation system 3, the high-density earthquake observation system 4, the lineside seismic motion evaluation system 5, the traffic control system 6, the operation resumption determination device 8, the operation information display device 10, and the operation resumption notification device 11 so that they can communicate with each other.

[0028] The operation resumption determination device 8 shown in Fig. 1, Fig. 2 and Fig. 4 is a device that determines whether or not operation can be resumed from the stop positions P1, P2, P4 of the trains T1, T2, T4 that stopped when the earthquake occurred. The operation resumption determination device 8 determines the stop positions P1, P2, P4 of the trains T1, T2, T4 and the trackside seismic motion G along the track R. D Based on the above, the operation resumption determination device 8 determines whether the trains T1, T2, and T4 that stopped during the earthquake can resume operation from the stop positions P1, P2, and P4. The operation resumption determination device 8 aims to quickly resolve train stops during an earthquake, thereby quickly rescuing passengers on the train. The operation resumption determination device 8 executes a predetermined operation resumption determination process according to an operation resumption determination program that determines whether the trains T1, T2, and T4 that stopped during an earthquake can resume operation from the stop positions P1, P2, and P4. The operation resumption determination device 8 is one of the network computers that constitute the operation resumption support system 1, and is a server that receives information from the earthquake disaster prevention system 2, the lineside earthquake motion evaluation system 5, and the traffic management system 6 and transmits the processing results to the operation resumption notification device 11. As shown in FIG. 4, the operation resumption determination device 8 includes a receiving unit 8a, an observed earthquake motion information storage unit 8b, a lineside earthquake motion information storage unit 8c, a position information storage unit 8d, an operation resumption permission unit 8e, an operation resumption determination program storage unit 8f, a transmitting unit 8g, and a control unit 8h.

[0029] The receiving unit 8a shown in Fig. 4 is a means for receiving lineside seismic motion information and position information from the earthquake disaster prevention system 2, lineside seismic motion evaluation system 5, and traffic control system 6 to the operation resumption determination device 8. The receiving unit 8a is a receiving device that receives observed seismic motion information transmitted by the earthquake disaster prevention system 2, lineside seismic motion information transmitted by the lineside seismic motion evaluation system 5, and position information transmitted by the traffic control system 6.

[0030] The observed earthquake motion information storage unit 8b is a means for storing the observed earthquake motion information output by the earthquake disaster prevention system 2. For example, as shown in FIG. 1(A) and FIG. 3(C), the observed earthquake motion information storage unit 8b stores the observed earthquake motion G A ~G C The observed earthquake motion information storage unit 8b stores the observed earthquake motion G A ~G C The stop section S1 where the travel distance exceeds the stop reference value Th1 is stored in association with the kilometre distance.

[0031] The lineside earthquake motion information storage unit 8c shown in FIG. 4 is a means for storing lineside earthquake motion information output by the lineside earthquake motion evaluation system 5. For example, as shown in FIG. 3(B), the lineside earthquake motion information storage unit 8c stores the lineside earthquake motion G D This is a storage device that stores the information in correspondence with kilometres as seismic motion information along the railway line.

[0032] The position information storage unit 8d shown in FIG. 4 is a means for storing the position information of the trains T1 to T4 output by the traffic control system 6. The position information storage unit 8d is a storage device that stores the current positions of the trains T1 to T4 managed by the traffic control system 6 as position information, for example, as shown in FIG. 3(A). The position information storage unit 8d stores the stop positions P1, P2, P4 and the running position P3 of each train T1 to T4 in correspondence with the kilometre distance. The position information storage unit 8d stores, for example, the types and positions of railway facilities such as stations α and β on the railway line R, railroad crossings, tunnels and bridges, together with the position information, as railway facility information. For example, the position information storage unit 8d updates and stores the stop position P1 of the train T1 that stops on the down line R1, the stop positions P2 and P4 of the trains T2 and T4 that stop on the up line R2, and the running position P3 of the train T3 that runs on the down line R1 in correspondence with the kilometre distance.

[0033] The operation restart permission unit 8e is D The movable section S where the inspection standard value Th2 is below 31 ,S 32 When trains T1 and T2 stop within the31 ,S 32 Other stop positions in P α The inspection standard value Th2 shown in FIG. 3(B) is a standard value for determining whether or not it is necessary to carry out inspection along the line after the occurrence of an earthquake. 21 is the section (inspection range) along the railway line that needs to be inspected after an earthquake occurs. 31 ~S 33 is a section (movable range) within which trains T1, T2, and T4 can be moved after an earthquake occurs without inspecting the trackside.

[0034] The operation restart permission unit 8e determines whether or not the trains T1 to T4 are stopped in the stop section S1 based on the observed seismic motion information output by the earthquake disaster prevention system 2 and the position information output by the traffic control system 6. The operation restart permission unit 8e determines whether or not the trains T1 to T4 are stopped in the stop section S1 based on the stop section S1 stored in the observed seismic motion information storage unit 8b and the current positions of the trains T1 to T4 stored in the position information storage unit 8d. The operation restart permission unit 8e extracts the trains T1, T2, and T4 that are stopped in the stop section S1, for example, as shown in FIG. 3.

[0035] The operation restart permission unit 8e determines the lineside earthquake motion G based on the lineside earthquake motion information output by the lineside earthquake motion evaluation system 5 and the position information of the trains T1 to T4 output by the traffic control system 6.

[0037] The operation resumption judgment program storage unit 8f shown in Fig. 4 is a means for storing an operation resumption judgment program for judging whether or not operation can be resumed from the stopping positions P1, P2, P4 of trains T1, T2, T4 that stopped when an earthquake occurred. The operation resumption judgment program storage unit 8f is a storage device that stores an operation resumption judgment program read from an information recording medium or an operation resumption judgment program downloaded through an electric communication line.

[0038] The transmission unit 8g is a means for transmitting operation resumption information from the operation resumption determination device 8 to the operation resumption notification device 11. The transmission unit 8g is a transmission device that transmits the operation resumption information output by the operation resumption permission unit 8e from the operation resumption determination device 8 to the operation resumption notification device 11 via the communication network 7.

[0039] The control unit 8h is a central processing unit (CPU) that controls various operations of the operation resumption judgment device 8. The control unit 8h executes operation resumption judgment processing according to an operation resumption judgment program. For example, the control unit 8h outputs the observed seismic motion information, lineside seismic motion information, and position information received from the receiving unit 8a to the observed seismic motion information storage unit 8b, lineside seismic motion information storage unit 8c, and position information storage unit 8d, instructs the observed seismic motion information storage unit 8b to store the observed seismic motion information, instructs the lineside seismic motion information storage unit 8c to store the lineside seismic motion information, instructs the position information storage unit 8d to store the position information, reads out the observed seismic motion information from the observed seismic motion information storage unit 8b and outputs the observed seismic motion information to the operation resumption permission unit 8e, The control unit 8h reads out lineside earthquake motion information from the lineside earthquake motion information storage unit 8c and outputs the lineside earthquake motion information to the operation restart permission unit 8e, reads out position information from the position information storage unit 8d and outputs it to the operation restart permission unit 8e, commands the operation restart permission unit 8e to determine whether the trains T1 to T4 are stopped in the stop section S1 or not, commands the operation restart permission unit 8e to permit the restart of operation of the trains T1 and T2, outputs the operation restart information output by the operation restart permission unit 8e to the transmission unit 8g, and commands the transmission unit 8g to transmit the operation restart information. The control unit 8h is connected to the receiving unit 8a, the observed earthquake motion information storage unit 8b, the lineside earthquake motion information storage unit 8c, the position information storage unit 8d, the operation restart permission unit 8e, the operation restart determination program storage unit 8f, and the transmission unit 8g so as to be able to communicate with each other.

[0040] The train control center 9 shown in Fig. 1, Fig. 2 and Fig. 4 is an organization that issues various commands to the crew members of trains T1 to T4. The train control center 9 is an operational organization where a dispatcher who performs command duties in the train control center 9 is employed, and the train control center 9 is an operational organization where the train control center 9 is operated. D A dispatcher performs tasks such as monitoring the train status and the operation status of trains T1 to T4 managed by the traffic control system 6. At the operation control center 9, the dispatcher issues instructions to the drivers of trains T1 and T2 via train radio or the like, for example, to resume operation of trains T1 and T2 from stopping positions P1 and P2 to the next station α at the slowest possible speed. The operation control center 9 is equipped with an operation information display device 10, an operation resumption notification device 11, and the like.

[0041] The operation information display device 10 shown in Figures 2 and 4 is a device that displays the operation status of trains T1 to T4. The operation information display device 10 displays on a screen operation information such as the current positions (on-line positions) of trains T1 to T4, the train numbers, destinations, and delay times of trains T1 to T4, which are managed by the traffic management system 6. As shown in Figure 3(A), the operation information display device 10 displays on a screen the stopping positions P1, P2, P4 of trains T1, T2, T4 and the running position P3 of train T3.

[0042] The operation resumption notification device 11 shown in Fig. 2 and Fig. 4 is a device that notifies a dispatcher of the operation resumption of trains T1 and T2. The operation resumption notification device 11 notifies a dispatcher of the judgment result of the operation resumption judgment device 8. When the operation resumption notification device 11 receives operation resumption information transmitted by the operation resumption judgment device 8, it notifies the dispatcher in the operation control center 9 visually or audibly. For example, the operation resumption notification device 11 notifies the dispatcher in the operation control center 9 of the operation resumption by displaying trains T1 and T2 that are permitted to resume operation as shown in Fig. 3(A) on the screen of a display device, or notifies the dispatcher in the operation control center 9 by a voice generated by a voice generating device.

[0043] Next, the operation of the driving restart support system according to the embodiment of the present invention will be described. In step (hereinafter, referred to as S) 100 shown in FIG. 5, the earthquake disaster prevention system 2 observes the earthquake motion at the observation point. When an earthquake occurs, the seismometer M shown in FIG. A ~M C The observed earthquake motion G at each observation point A ~G C The earthquake disaster prevention system 2 transmits the observed seismic motion along the line evaluation system 5 and the service resumption determination device 8. In addition, the earthquake observation system 3 transmits the observed seismic motion at each observation point measured by seismometers of public institutions to the line seismic motion evaluation system 5, and the high-density earthquake observation system 4 transmits the high-density observed seismic motion at each observation point continuously measured along the line to the line seismic motion evaluation system 5.

[0044] In S200, observed earthquake motion G A ~G CThe earthquake disaster prevention system 2 judges whether the observed earthquake motion G exceeds the stop reference value Th1. A ~G C When the earthquake disaster prevention system 2 judges that the observed earthquake motion G exceeds the stop reference value Th1, the process proceeds to S300. A ~G C When the earthquake disaster prevention system 2 determines that falls below the stop reference value Th1, the process proceeds to S400.

[0045] In S300, the earthquake disaster prevention system 2 brings trains T1, T2, and T4 to an emergency stop. As shown in FIG. 3(B), the observed seismic motion G A ,G B When trains T1, T2, and T4 are present in a stop section S1 where the stop reference value Th1 is exceeded, the earthquake disaster prevention system 2 brings the trains T1, T2, and T4 present in the stop section S1 to an emergency stop.

[0046] In S400, the earthquake disaster prevention system 2 does not perform an emergency stop of the train T3. As shown in FIG. 3(B), the observed earthquake motion G C When the train T3 is located outside the stop section S1 where the stop reference value Th1 is smaller than the stop reference value Th1, the earthquake disaster prevention system 2 does not make an emergency stop of the train T3 located outside the stop section S1.

[0047] In S500, the railway line earthquake motion evaluation system 5 evaluates the earthquake motion along the railway line. When the railway line earthquake motion evaluation system 5 receives observed earthquake motion information from the earthquake disaster prevention system 2 or the earthquake observation system 3, it calculates the railway line earthquake motion G according to the kilometer distance of the railway line R as shown in FIG. 1(C) and FIG. 3(B). D The railway line earthquake motion evaluation system 5 estimates the railway line earthquake motion G according to the kilometer distance of the track R as shown in Fig. 1(C) and Fig. 3(B). D The railway line earthquake motion evaluation system 5 evaluates the railway line earthquake motion G D The lineside earthquake motion evaluation system 5 transmits this to the service resumption determination device 8 as lineside earthquake motion information.

[0048] In S600, the traffic control system 6 detects the positions of trains T1 to T4. For example, as shown in Fig. 3(A) and (B), the traffic control system 6 detects the stop positions P1, P2, and P4 of trains T1, T2, and T4, and transmits the position information of trains T1, T2, and T4 to the operation resumption determination device 8. In addition, for example, the traffic control system 6 detects the running position P3 of train T3 located outside the stop section S1, and transmits the position information of train T3 to the operation resumption determination device 8.

[0049] In S700, the operation resumption determination device 8 executes an operation resumption determination process for determining whether or not the operation of the trains T1, T2, and T4 can be resumed. D The operation resumption determination device 8 determines whether trains T1 to T4 are on the line in the stop section S1 where the stop threshold Th1 exceeds the stop reference value Th1, and identifies the trains T1, T2, and T4 stopped in the stop section S1. Next, as shown in Figures 3(A) and (B), the operation resumption determination device 8 determines whether the trains T1, T2, and T4 that stopped at stop positions P1, P2, and P4 when the earthquake occurred should resume operation from the stop positions P1, P2, and P4.

[0050] In S800, the operation restart notification device 11 notifies the dispatcher that the trains T1 and T2 have restarted. When the dispatcher in the operation control center 9 commands the drivers of the trains T1 and T2 to restart the trains T1 and T2 by train radio or the like, the drivers of the trains T1 and T2 restart the trains T1 and T2 from the stopping positions P1 and P2 at the slowest speed. As a result, the movable section S 31 ,S 32 Trains T1 and T2 travel to station α within the network, and passengers on trains T1 and T2 get off at station α.

[0051] Next, the operation of the operation resumption determination device according to the embodiment of the present invention will be described. The following description will be centered on the operation of the operation restart permission unit 8e shown in FIG. In S710 shown in Fig. 6, the seismic motion along the railway line G D The operation restart permission unit 8e judges whether the seismic motion along the railway line G DThe movable range S where the inspection standard value Th2 is below 31 ~S 33 The operation restart permission unit 8e judges whether the trains T1, T2, and T4 are stopped within the period. D When the operation restart permission unit 8e judges that the inspection reference value Th2 is exceeded, the process proceeds to S720. D When the operation restart permission unit 8e determines that exceeds the inspection reference value Th2, the process proceeds to S730.

[0052] In S720, the operation restart permission unit 8e permits the trains T1 and T2 to restart. In the conventional early earthquake warning system, the seismometers M B Observed earthquake motion G B is determined to be constant between these, so the observed seismic motion G B exceeds the inspection standard value Th2. For this reason, in the conventional earthquake early warning system, the train T1 stopped at the stop position P1 cannot be moved until the inspection between the boundary AB and the boundary BC is completed. On the other hand, in this embodiment, as shown in FIG. 3(B), the train T1 along the line seismic motion G D can be evaluated in detail at each position on the railway line R. Therefore, in this embodiment, the seismic motion along the railway line G D In the section where the ground motion G exceeds the inspection standard value Th2, the train T2 cannot be moved from the stop position P2. D For example, as shown in FIG. 3B, in the section between the stop position P2 and the station α, the train T2 can be moved if the seismic motion G D Since the train T2 can move from the stop position P2 to station α because the train T2 is continuously below the inspection standard value Th2, the train T2 can move from the stop position P2 to station α. D The movable range S where the inspection standard value Th2 is below 31 ,S 32 For trains T1 and T2 that are stopped within the 31 ,S 32 The operation restart permission unit 8e allows the trains T1 and T2 in the train group T1 and T2 to restart. A ,GB Even if trains T1 and T2 are stopped because the train stop threshold Th1 is exceeded, the seismic motion G D When the threshold value Th2 falls below the inspection standard value Th2, the trains T1 and T2 can be moved immediately to station α without safety checks by staff.

[0053] In S730, the operation restart permission unit 8e does not permit the restart of the train T4. For example, as shown in FIG. 3B, the line-side earthquake motion G D There are some sections where the seismic motion G along the railway line is below the inspection standard value Th2. D There is a section between the stop position P4 and the station β where train T4 can be moved without inspecting the trackside after the earthquake. 33 However, inspection section S requires inspection after an earthquake. 21 Therefore, train T4 cannot move from stop position P4 to station β. D The movable range S exceeds the inspection standard value Th2 33 As for the train T4 stopped outside, the operation restart permission unit 8e does not permit the train T4 to restart operation. As a result, the train T4 remains stopped at the stop position P4 until the safety of the railway facility is confirmed by an attendant.

[0054] The driving resumption determination device and driving resumption support system according to the embodiment of the present invention have the following effects. (1) In this embodiment, the seismic ground motion G D The movable section S where the inspection standard value Th2 is below 31 ,S 32 When trains T1 and T2 stop within the 31 ,S 32 Other stop positions in P α The operation restart permission unit 8e allows the trains T1 and T2 to restart operation until the trains T1 and T2 stop at the stop positions P1 and P2. αAs a result, trains T1 and T2 that stopped when the earthquake occurred can quickly resume operation from stopping positions P1 and P2.

[0055] (2) In this embodiment, the lineside earthquake motion G is set to be smaller than the inspection standard value Th2, which is a standard for whether or not it is necessary to carry out a lineside inspection after an earthquake occurs. D The movable section S is smaller than 31 ,S 32 Other stop positions in P α The operation restart permission unit 8e allows the trains T1 and T2 to resume operation until the trains T1 and T2 reach their stop positions P1 and P2. This allows the trains T1 and T2, which are stopped during the earthquake, to move quickly from their stop positions P1 and P2. As a result, trains that are stopped during the earthquake can resume operation early.

[0056] (3) In this embodiment, the seismic ground motion G D The movable section S where the inspection standard value Th2 is below 31 ,S 32 The operation restart permission unit 8e permits the restart of operation of the trains T1 and T2 to the station α within the station. Therefore, for example, the trains T1 and T2 stopped between stations during an earthquake can be made to run at the slowest speed to the next station α, and passengers can be made to disembark from the trains T1 and T2 quickly at the station α. ​​As a result, trains stopped between stations during an earthquake can be quickly restarted, and passengers can be quickly rescued.

[0057] (4) In this embodiment, the seismic ground motion G D Based on the lineside earthquake motion information output by the lineside earthquake motion evaluation system 5 that evaluates the lineside earthquake motion G D The movable section S where the inspection standard value Th2 is below 31 ,S 32 Other stop positions in P αThe operation restart permission unit 8e allows the trains T1 and T2 to resume operation until the train stops P1 and P2 reach the next station α. ​​For this reason, for example, when it is confirmed by referring to detailed lineside earthquake motion information that the earthquake motion between the trains T1 and T2's stopping positions P1 and P2 and the next station α does not reach the inspection implementation standard value, the trains T1 and T2 can be made to run to the next station α at the slowest possible speed. As a result, it is possible to support the resumption of operation after an earthquake in railways. In addition, for railway operators who have introduced the Railway Earthquake Damage Estimation Information Distribution System (DISER), the scope of use can be further expanded by adding an operation restart support function. Furthermore, it is possible to provide information that supports the early resumption of operation of the trains T1, T2, and T4 from the stopping positions P1, P2, and P4 by successively updating lineside earthquake motion information after an earthquake occurs.

[0058] (5) In this embodiment, the railway line earthquake motion evaluation system 5 evaluates earthquake motion along the railway line based on observed earthquake motion information on high-density earthquake motion continuously observed along the railway line. Therefore, based on the high-density observed earthquake motion information output by the high-density earthquake observation system 4, earthquake motion along the railway line can be observed with high accuracy, and railway line earthquake motion information can be easily understood.

[0059] (6) In this embodiment, the seismometer M A ~M C Based on the observed earthquake motion information on earthquake motion at each observation point observed by the system, the railway line earthquake motion evaluation system 5 evaluates the earthquake motion along the railway line. For this purpose, the railway line earthquake motion evaluation system 5 estimates the surface earthquake motion distribution by spatial interpolation using only the observed earthquake motions from seismometers of public institutions such as K-NET output by the external earthquake observation system 3, and then calculates the railway line earthquake motion G D The company can extract the observed earthquake motion G output from its earthquake disaster prevention system 2 to generate seismic motion information along the railway line. A ~G C The seismic motion distribution along the railway line G is estimated by spatial interpolation using both the observed seismic motion output by the external earthquake observation system 3 and the observed seismic motion output by the external earthquake observation system 4. D By extracting these, seismic motion information along the railway line can be generated.

[0060] (7) In this embodiment, the operation resumption notification device 11 notifies the dispatcher of the resumption of operation of the trains T1 and T2. Therefore, the dispatcher can notify the drivers of the trains T1 and T2 of the resumption of operation by train radio or the like, and the safe stopping position P α Trains T1 and T2 can move at the slowest possible speed until

[0061] The present invention is not limited to the above-described embodiment, and various modifications and variations are possible as described below, which are also within the scope of the present invention. (1) In this embodiment, the trains T1 to T4 are railroad vehicles such as Shinkansen or conventional railroad cars, but the invention can also be applied to other moving bodies such as magnetic levitation railroad cars, single-rail (monorail) cars, guideway (new transit system) cars, or automobiles. Also, in this embodiment, the stations α and β used as stations to check passenger status are used as examples, but the invention can also be applied to stations such as freight stations used for loading and unloading cargo, signal stations used for trains passing or waiting, and marshalling yards used for shunting cars and forming trains. Furthermore, in this embodiment, the trains T1 and T2 stopped between stations are moved within a movable range S 31 ,S 32 Other stop positions P α Although the above description has been given with an example of allowing trains T1 and T2 to resume operation until the train reaches station α, this invention is not limited to the case of moving trains T1 and T2 to station α. ​​For example, this invention can also be applied to the case of moving a train that is stopped within a railway crossing, a tunnel, or a bridge within the movement range to another stopping position outside the railway crossing, outside the tunnel, or outside the bridge within this movement range. In this case, for example, when a train is stopped straddling a railway crossing, the crossing gates can be raised by moving the train within the movement range outside the railway crossing. Similarly, in this embodiment, trains T1 and T2 stopped at stopping positions P1 and P2 are moved to the movement range S within the movement range S. 31 ,S 32The above description is given as an example of a case where operation is permitted to be resumed up to the nearest station α, but the present invention can also be applied to a case where operation is permitted to be resumed up to a station other than the next station α as long as it is within the movable range.

[0062] (2) In this embodiment, the observed earthquake motion information output by the earthquake disaster prevention system 2, earthquake observation system 3, and high-density earthquake observation system 4 is used as an example, but the present invention can also be applied to cases where any one of these, or any combination of these, is used as observed earthquake motion information. Also, in this embodiment, the high-density earthquake observation system 4 observes earthquake motion along the railway line at high density using distributed acoustic measurement as an example, but the present invention is not limited to observation using distributed acoustic measurement. For example, by placing a large number of seismometers at high density on the railway line R, it is possible to observe earthquake motion along the railway line in detail. Furthermore, in this embodiment, if seismometers M are placed along the railway line, A ~M C Although an example has been described in which three seismometers are installed, the number of installed sensors is not limited to three, and the present invention can also be applied to cases in which two or less seismometers or four or more seismometers are installed.

[0063] (3) In this embodiment, the case where the dispatcher of the operation control center 9 notifies the drivers of the trains T1 and T2 of the resumption of operation by radio has been described as an example, but the present invention can also be applied to a case where the drivers of the trains T1 and T2 are notified of the resumption of operation by a mobile terminal carried by them. In addition, in this embodiment, the case where the drivers of the trains T1 and T2 are notified by the dispatcher of the operation control center 9 to resume operation from the stop positions P1 and P2 has been described as an example, but the present invention is not limited to such a method of resuming operation. For example, the present invention can also be applied to a case where the trains T1 and T2 are automatically resumed from the stop positions P1 and P2 by an automatic train operation system (Automatic Train Operation (ATO)) that automatically operates the trains T1 to T4.
