Description

This invention relates to a driving resumption determination device that determines whether or not driving can be resumed from the stopping position of a moving body that has stopped when an earthquake occurs, and a driving resumption support system that supports the early resumption of driving from the stopping position of a moving body that has stopped when an earthquake occurs.

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 measurements from seismometers installed at regular intervals along the line by the railway operator exceed a predetermined standard value, operational 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 the earthquake is harmful based on the seismic motion information, and if it is determined that the earthquake is harmful, it stops the supply of power to the train and stops the train's operation.

The Damage Information System for Earthquake on Railway (DISER) (registered trademark) has been developed with the aim of providing information to help trains resume operations as soon as possible, and can obtain area-wide seismic motion distribution after an earthquake occurs, detailed estimated information on seismic motion along registered lines, and estimated damage rank information for railway structures. This system uses public earthquake information released immediately after an earthquake occurs and a ground database to estimate area-wide seismic motion distribution, estimate seismic motion along the tracks and the damage rank of structures due to this seismic motion, and instantly distributes the estimated information to railway operators (for example, see Non-Patent Document 1). This system quickly resumes train operations based on the estimated information.

When a large earthquake is detected by seismometers along railway lines and the observed seismic motion exceeds a predetermined standard value, operational restrictions are put in place, such as immediately bringing trains in operation to an emergency stop. After that, staff visually inspect the condition of railway facilities such as structures along the line, and once safety is confirmed, train operations are resumed. However, since this inspection is carried out by humans on foot, it takes a long time, and train operations cannot be resumed until all inspections have been completed and safety has been 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.

The objective of this invention is to provide a resumption of operation determination device and a resumption of operation support system that can quickly resume operation of a moving object that has stopped during an earthquake from its stopped position.

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 the trains T ₁ to T ₄ run. The track R is a double track consisting of two main lines, and is composed of a down line R ₁ on which the down trains T ₁ and T ₃ run from the starting point to the end point, and an up line R ₂ on which the up trains T ₂ and T ₃ run from the end point to the starting point. The trains T ₁ to T ₄ are moving bodies that move along the track R. The trains T ₁ to T ₄ are Shinkansen trains that run on the Shinkansen (registered trademark) or conventional trains that run on conventional lines. The trains T ₁ to T ₄ 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 vehicles.

The operation restart support system 1 shown in Fig. 1 and Fig. 2 is a system that supports early operation restart from the stop positions _P1 , _P2 , _P4 of trains _T1 , _T2 , _T4 that have stopped during an earthquake. The operation restart support system 1 evaluates the areal seismic motion distribution and the linear seismic motion distribution along the track R on which the trains _T1 to _T4 run, based on observed seismic motion information observed immediately after an earthquake, and determines whether or _not early operation can be restarted from the stop positions _P1 , _{P2 , P4} of _the trains _T1 , _T2 , _{T4 that} have stopped during an earthquake and the trackside seismic motion _GD . The operation restart support system 1 is _, for example, _a system for supporting early resumption of operation of trains stopped between stations after an earthquake, in order to quickly resolve trains stopped between stations during an earthquake. The operation resumption support system 1 includes an earthquake disaster prevention system 2 shown in Figures 1 and 2, an earthquake observation system 3, a high-density earthquake observation system 4, a railway line seismic motion evaluation system 5, an operation control system 6, a communication network 7 shown in Figures 2, an operation resumption determination device 8 shown in Figures 1 and 2, an operation information display device 10 shown in Figure 2, and an operation resumption notification device 11.

The earthquake disaster prevention system 2 shown in Fig. 1 and Fig. 2 is a system that observes seismic motion at each observation point by seismometers M _A to M _C shown in Fig. 3. Here, seismic motion refers to the shaking of the ground during an earthquake. Indicators that represent seismic motion used for train operation restrictions during an earthquake include maximum acceleration for warning, spectral intensity (Spectral Intensity value (SI value)), measured seismic intensity, maximum acceleration (Peak Ground Acceleration (PGA)) which is the maximum amplitude value (absolute value) of an acceleration record, and maximum speed (Peak Ground Velocity (PGV)) which is the maximum amplitude value (absolute value) of a speed record. The earthquake disaster prevention system 2 is an early earthquake warning system that estimates earthquake specifications and performs operation restrictions based on initial microtremor data of seismic motion for several seconds, for example. The earthquake disaster prevention system 2 includes early warning seismometers installed at each observation point to measure and record seismic motion, a relay server that relays seismic motion information between each seismometer and transmits and manages the seismic motion information, and a monitoring terminal that monitors each seismometer and the relay server. The earthquake disaster prevention system 2, for example, observes relatively sparse earthquake motion using the railway operator's own seismometers at each observation point placed at intervals along the railway line. The earthquake disaster prevention system 2 can also use, for example, observed earthquake motion information output by the earthquake observation system 3. The earthquake disaster prevention system 2 detects earthquake motion at each observation point as observed earthquake motions G _A to G _C using seismometers M _A to M _C as shown in Figures 3(B) and (C). The earthquake disaster prevention system 2 outputs the observed earthquake motions G _A to G _C observed by the seismometers M _A to M _C at each observation point to the railway line earthquake motion evaluation system 5 and the operation resumption determination device 8 as observed earthquake motion information.

The earthquake disaster prevention system 2 shown in Fig. 1 and Fig. 2 judges whether or not the trains T ₁ to T ₄ traveling on the track R should be stopped in an emergency when an earthquake occurs. As shown in Fig. 3 (A) and (B), when the trains T ₁ , T ₂ , and T 4 are traveling in the stop section S ₁ where the observed seismic motions G _A and G _B exceed the stop reference value Th ₁ , _the earthquake disaster prevention system 2 judges that the trains T ₁ , T ₂ , and T ₄ traveling in this stop section S ₁ should be stopped in an emergency. On the other hand, when the train T ₃ is traveling outside the stop section S ₁ where the observed seismic motion G _C is below the stop reference value Th ₁ , the earthquake disaster prevention system 2 judges that the train T ₃ traveling outside the stop section S ₁ should not be stopped in an emergency. Here, the stop reference value Th ₁ shown in Fig. 3 (B) is a reference value when judging whether or not the trains T ₁ to T ₄ should be stopped after the occurrence of an earthquake. The stop section _S1 shown in Figures 3(B) and (C) is a section where trains _T1 , _T2 , and _T4 must be stopped after an earthquake occurs. Boundary A-B is the boundary between the section covered by seismometer M _A and the section covered by seismometer M _B. Boundary B-C is the boundary between the section covered by seismometer M _B and the section covered by seismometer M _C. When it is necessary to make an emergency stop of trains _T1 to _T4 in the event of an earthquake, earthquake disaster prevention system 2 automatically stops the power supplied to trains _T1 to _T4 to activate emergency brakes of trains _T1 to _T4 , or issues an emergency stop command to the drivers of trains _T1 to _T4 via train radio.

Unlike the earthquake disaster prevention system 2, which observes seismic motion using its own seismometers M _A to M _C , the earthquake observation system 3 observes seismic motion using seismometers installed at each observation point by an external public institution such as the Japan Meteorological Agency or the National Research Institute for Earth Science and Disaster Resilience. The earthquake observation system 3 uses, for example, seismic motion information (Earthquake Early Warning) 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 Institute 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).

The high-density earthquake observation system 4 is a system that observes 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), which uses, for example, optical fiber cables as sensors to measure distributed strain. 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 transmitter/receiver 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 transmitter/receiver. The high-density earthquake observation system 4 compares the reflected signal received when the length of the optical fiber cable changes during an earthquake with the reflected signal received under normal circumstances, and observes seismic motion by detecting the 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 very high-density observations at low cost compared to observations 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.

The lineside earthquake motion evaluation system 5 shown in Figures 1 and 2 is a system that evaluates 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 Figure 1, the lineside earthquake motion evaluation system 5 estimates earthquake motion along the track R based on observed earthquake motion information at each observation point output by the earthquake observation system 3, and estimates earthquake motion along the track 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 the characteristics of the ground 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 from each observation point, performs spatial interpolation using the estimated input earthquake motion of the foundation, and calculates 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.

The lineside earthquake motion evaluation system 5 evaluates earthquake motion along the line based on observed earthquake motion information related to high-density earthquake motion along the line observed, for example, by distributed acoustic measurement. 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 the 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.

The lineside earthquake motion evaluation system 5 extracts lineside earthquake motion _GD from the planar 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, and generates lineside earthquake motion information in which the lineside earthquake motion _GD corresponds to the kilometer distance as shown in Fig. 1 (A) and Fig. 3. The lineside earthquake motion evaluation system 5 extracts lineside earthquake motion _GD based on the observed earthquake motion information output by the high-density earthquake observation system 4, and generates lineside earthquake motion information in which the lineside earthquake motion _GD corresponds to the kilometer distance as shown in Fig. 1 (B) and Fig. 3. Here, the kilometer distance shown in Fig. 1 (A) (B) and Fig. 3 is the track extension (distance) from the starting point of the track R, and is generally set to an ascending order from the starting point to the end point. For example, as shown in Fig. 3, the lineside earthquake motion evaluation system 5 estimates lineside earthquake motion _GD along the down line _R1 and the up line _R2 based on the observed earthquake motion observed by the earthquake observation system 3. As shown in Fig. 1(C) and Fig. 3(B), the lineside earthquake motion evaluation system 5 generates a waveform representing the lineside earthquake motion _GD corresponding to the kilometer distance when the vertical axis represents the earthquake motion and the horizontal axis represents the kilometer distance. The lineside earthquake motion evaluation system 5 outputs lineside earthquake motion information (estimated earthquake motion information) that corresponds the lineside earthquake motion _GD to the kilometer distance to the service resumption determination device 8.

The traffic control system 6 shown in Fig. 1 and Fig. 2 is a system that manages the operation of trains _{T1 to T4} . The traffic control system 6 is a system that supports operations for smoothly advancing the operation of trains _T1 to _T4 . For example, the traffic control system 6 is a train traffic control system (Programmed Traffic Control (PTC)) that centrally manages and controls trains T1 to _T4 based on a train diagram in railway train traffic control. For example, as shown in Fig. 3 (A), the traffic control system 6 detects the stop position _P1 of train _T1 that stopped on the down line _R1 when an earthquake occurred, and detects the stop positions _P2 , _P4 of trains _T2 , _T4 that stopped on the up line _R2 when an earthquake occurred. The traffic control system 6 constantly monitors the operating status of trains _T1 to _T4 , detects the running positions _P3 and stopping positions _P1 , _P2 , and _P4 of trains _T1 to _T4 on the track R, and outputs the current positions of 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.

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 judgment 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 judgment device 8, transmits position information from the operation management system 6 to the operation resumption judgment device 8 and the operation information display device 10, and transmits operation resumption information from the operation resumption judgment 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 operation management system 6, the operation resumption judgment device 8, the operation information display device 10, and the operation resumption notification device 11 so that they can communicate with each other.

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 an earthquake occurred. The operation resumption determination device 8 determines whether or not the trains _T1 , _T2 , _T4 that stopped when an earthquake occurred can resume operation from the stop positions _P1 , _P2 , _P4 based on the stop positions _P1 , _P2 , _P4 of the trains _T1 , _T2 , _T4 and the trackside seismic motion _GD along the track R. The operation resumption determination device 8 aims to quickly resolve trains that are stopped when an earthquake occurs, thereby quickly rescuing passengers on the trains. The operation resumption determination device 8 executes a predetermined operation resumption determination process according to an operation resumption determination program 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 an earthquake occurred. The operation resumption determination device 8 is one of the network computers constituting 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 control 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.

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 management 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 management system 6. The receiving unit 8a outputs the observed seismic motion information, lineside seismic motion information, and position information received from the earthquake disaster prevention system 2, lineside seismic motion evaluation system 5, and traffic management system 6 via the communication network 7 to the control unit 8h.

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 is a storage device that stores the observed earthquake motions G _A to G _C along the railway line observed by the earthquake disaster prevention system 2 as observed earthquake motion information in association with kilometres. The observed earthquake motion information storage unit 8b stores the stop section S ₁ where the observed earthquake motions G _A to G _C exceed the stop reference value Th ₁ in association with kilometres.

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. The lineside earthquake motion information storage unit 8c is a storage device that stores, as lineside earthquake motion information, the lineside earthquake motion G _D evaluated by the lineside earthquake motion evaluation system 5 in association with kilometres, as shown in Fig. 3(B), for example.

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 of the trains _T1 to _T4 in association with the kilometre distance. The position information storage unit 8d stores, for example, the types and positions of railway facilities such as stations α, β, etc. on the track R, railroad crossings, tunnels and bridges, as railway facility information together with the position information. The position information storage unit 8d, for example, updates and stores the stopping position _P1 of train _T1 stopping on the down line _R1 , the stopping positions _P2 , _P4 of trains _T2 , _T4 stopping on the up line _R2 , and the running position _P3 of train _T3 running on the down line _R1 in correspondence with the kilometres.

The operation resumption permission unit 8e is a _means for permitting the resumption of operation of the trains T1, T2 to another stop position _Pα in the movable sections _S31 , _S32 when the trains _T1 , _T2 stop in the movable sections _S31 , _S32 where the trackside earthquake motion _GD is below _the inspection reference value _Th2 . Here, the inspection reference value _Th2 shown in FIG. 3(B) is a reference value when determining whether or not it is necessary to carry out a trackside inspection after the occurrence of an earthquake. The inspection section _S21 shown in FIG. 3(B) and (C) is a section (inspection range) where it is necessary to carry out a trackside inspection after the occurrence of an earthquake. The movable sections _S31 to _S33 are sections (movable ranges) where the trains _T1 , _T2 , _T4 can be moved even if a trackside inspection is not carried out after the occurrence of an earthquake.

The operation restart permission unit 8e judges whether 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 judges whether 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 stopped in the stop section _S1 , for example, as shown in FIG.

The operation restart permission unit 8e permits the trains _T1 , _T2 to resume operation up to another stop position Pα within the movable range _S31 , _S32 where the lineside earthquake motion _GD is below the inspection reference value _Th2 , 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. For example, as shown in Figs. 3(A) and 3(B), the operation restart permission unit 8e permits the trains _T1 , _T2 within the movable section _S31 , _S32 where the lineside earthquake motion _GD is below the inspection reference value _Th2 to resume operation from the stop positions _P1 , _P2 within the movable section _S31 , _S32 to the stop position _Pα . On the other hand, the operation restart permission unit 8e does not permit the train _T4 outside the movable section _S33 where the lineside earthquake motion _GD is greater than the inspection reference value _Th2 to resume operation from the stop position _P4 .

The operation restart permission unit 8e permits the resumption of operation of the trains _T1 , _T2 to stations α in the movable sections _S31 , _S32 where the trackside earthquake motion _GD is below the inspection standard value _Th2 . For the train T1 stopped at a stop position _P1 in the movable section _S31 where the trackside earthquake motion _GD is below the inspection standard value _Th2 , the operation restart permission unit 8e permits the train _T1 to move to the nearest station α in the movable section _S31 as shown by the two-dot chain line in the figure. For the train _T2 stopped at a stop position _P2 in the movable section _S32 where the trackside earthquake motion _GD is below the inspection standard value _Th2 , the operation restart permission unit _8e permits the train _T2 to move to the nearest station α in the movable section _S32 as shown by the two-dot chain line in the figure. The operation restart permission unit 8e outputs the permission or not of restarting the operation of the trains T ₁ , T ₂ , and T ₄ to the control unit 8h as operation restart information.

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 the operation resumption judgment program read from an information recording medium or the operation resumption judgment program downloaded through an electric communication line.

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

The control unit 8h is a central processing unit (CPU) that controls various operations of the operation resumption determination device 8. The control unit 8h executes operation resumption determination processing according to an operation resumption determination program.

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 judgment program storage unit 8f, and the transmission unit 8g so as to be able to communicate with each other.

The operation control center 9 shown in Fig. 1, Fig. 2 and Fig. 4 is an organization that issues various commands to the crew members of the trains _T1 to _T4 . The operation control center 9 is an operational organization where a dispatcher who performs command duties in the operation control center 9 is employed, and the dispatcher performs duties such as monitoring the wayside earthquake motion _GD evaluated by the wayside earthquake motion evaluation system 5 and monitoring the operation status of the trains _T1 to _T4 managed by the operation control system 6. For example, the dispatcher in the operation control center 9 issues instructions to the drivers of the trains _T1 and _T2 via train radio or the like to resume operation of the trains _T1 and _T2 from the stopping positions _P1 and _P2 to the next station α at the slowest speed. The operation control center 9 is equipped with an operation information display device 10, an operation resumption notification device 11, and the like.

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-track positions) of trains _T1 to _T4 , the train numbers, destinations, and delay times of trains _T1 to _T4 , which are managed by the operation management system 6. As shown in Figure 3(A), the operation information display device 10 displays on a screen the stop positions _P1 , _P2 , _P4 of trains _T1 , _T2 , _T4 and the running position _P3 of train _T3 .

The operation resumption notification device 11 shown in Fig. 2 and Fig. 4 is a device that notifies a dispatcher of the resumption of operation of the trains _T1 and _T2 . The operation resumption notification device 11 notifies the 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 resumption of operation by displaying the trains _T1 and _T2 that are permitted to be resumed 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.

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 seismic motion at the observation points. When an earthquake occurs, the earthquake disaster prevention system 2 transmits the observed seismic motion G _A to G _C at each observation point measured by seismometers M _A to M _C shown in Fig. 3 (B) and (C) to the lineside seismic motion evaluation system 5 and the operation 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 lineside 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 lineside seismic motion evaluation system 5.

In S200, the earthquake disaster prevention system 2 determines whether the observed seismic motions G _A to G _C exceed the stop reference value Th _1. When the earthquake disaster prevention system 2 determines that the observed seismic motions G _A to G _C exceed the stop reference value Th ₁ , the process proceeds to S300, and when the earthquake disaster prevention system 2 determines that the observed seismic motions G _A to G _C fall below the stop reference value Th ₁ , the process proceeds to S400.

In S300, the earthquake disaster prevention system 2 brings the trains _T1 , _T2 , and _T4 to an emergency stop. As shown in Fig. 3(B) , when the trains _T1 , _T2 , and _T4 are located in a stop section _S1 where the observed seismic motions G _A and G _B exceed a stop reference value _Th1 , the earthquake disaster prevention system 2 brings the trains _T1 , _T2 , and _T4 located in the stop section _S1 to an emergency stop.

In S400, the earthquake disaster prevention system 2 does not make an emergency stop of the train _T3 . As shown in Fig. 3(B) , when the train _T3 is located outside the stop section _S1 where the observed seismic motion _Gc is below 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 .

In S500, the lineside earthquake motion evaluation system 5 evaluates the earthquake motion along the line. When the lineside earthquake motion evaluation system 5 receives observed earthquake motion information from the earthquake disaster prevention system 2 or the earthquake observation system 3, the lineside earthquake motion evaluation system 5 estimates the lineside earthquake motion G _D corresponding to the kilometre of the track R as shown in Fig. 1 (C) and Fig. 3 (B). Also, when the lineside earthquake motion evaluation system 5 receives observed earthquake motion information from the high-density earthquake observation system 4, the lineside earthquake motion evaluation system 5 evaluates the lineside earthquake motion G _D corresponding to the kilometre of the track R as shown in Fig. 1 (C) and Fig. 3 (B). As a result, the lineside earthquake motion evaluation system 5 transmits the lineside earthquake motion G _D to the operation resumption determination device 8 as lineside earthquake motion information.

In S600, the traffic control system 6 detects the positions of the trains _T1 to _T4 . For example, as shown in Figures 3(A) and 3(B), the traffic control system 6 detects the stop positions _P1 , _P2 , _{and P4 of} the trains _T1 , _T2 , and T4, and transmits the position information of the trains _T1 , _T2 , and _T4 to the operation resumption determination device 8. Also, for example, the traffic control system 6 detects the running position _P3 of the train _T3 located outside the stop section _S1 , and transmits the position information of the train _T3 to the operation resumption determination device 8.

In S700, the operation resumption determination device 8 executes an operation resumption determination process for determining whether or not operation of the trains _T1 , _T2 , and _T4 can be resumed. First, the operation resumption determination device 8 determines whether or not the trains _T1 to _T4 are located in the stop section _S1 where the trackside earthquake motion _GD exceeds the stop reference value _Th1 , and identifies the trains _T1 , _T2 , and _T4 that are stopped in the stop section _S1 . Next, as shown in Figures 3(A) and (B) , the operation resumption determination device 8 determines whether or not operation of the trains _T1 , _T2 , and _T4 that stopped at the stop positions _P1 , _P2 , and _P4 when the earthquake occurred should be resumed from the stop positions _P1 , _P2 , and _P4 .

In S800, the operation resumption notification device 11 notifies the dispatcher that the trains _T1 and _T2 have resumed operation. When the dispatcher in the operation control center 9 commands the drivers of the trains _T1 and _T2 to resume operation of the trains _T1 and _T2 by train radio or the like, the drivers of the trains _T1 and _T2 resume operation of the trains _T1 and _T2 at the slowest speed from the stopping positions _P1 and _P2 . As a result, the trains _T1 and _T2 move to stations α within the movable sections _S31 and _S32 , and the passengers on the trains _T1 and _T2 get off at station α.

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 operation restart permission unit 8e judges whether the wayside earthquake motion _GD falls below the inspection reference value _Th2 . As shown in Fig. 3, the operation restart permission unit 8e judges whether the trains _T1 , _T2 , _{and T4} are stopped within the movable range _S31 to _S33 where the wayside earthquake motion _GD falls below the inspection reference value _Th2 . When the operation restart permission unit 8e judges that the wayside earthquake motion _GD falls below the inspection reference value _Th2 , the process proceeds to S720, and when the operation restart permission unit 8e judges that the wayside earthquake motion _GD exceeds the inspection reference value Th2, the process proceeds to S730.

In S720, the operation restart permission unit 8e permits the restart of operation of the trains T ₁ and T _2. In the conventional earthquake early warning system, the observed seismic motion G _B observed by the seismometer M _B , which is responsible for the area between the boundary A-B and the boundary B-C shown in FIG. 3B, is determined to be constant between these boundaries, and therefore the observed seismic motion G _B is determined to exceed the inspection standard value Th _2. For this reason, in the conventional earthquake early warning system, the train T ₁ stopped at the stop position P ₁ cannot be moved until the inspection between the boundary A-B and the boundary B-C is completed. On the other hand, in this embodiment, as shown in FIG. 3B, the trackside seismic motion G _D can be evaluated in detail at each position on the track R compared to the conventional earthquake early warning system. For this reason, in this embodiment, the train T ₂ cannot be moved from the stop position P ₂ in the section where the trackside seismic motion G _D exceeds the inspection standard value Th ₂ , but the train T ₂ can be moved in the section where the trackside seismic motion G _D is below the inspection standard value Th ₂ . For example, as shown in Fig. 3B, the trackside earthquake motion _GD is continuously below the inspection reference value _Th2 between the stop position _P2 and station α, so that the train _T2 can be moved from the stop position _P2 to station α. For this reason, for the trains _T1 and _T2 stopped within the movable ranges _S31 and _S32 where the trackside earthquake motion _GD is below the inspection reference value _Th2 , the operation restart permission unit 8e permits the trains _T1 and _T2 within the movable ranges _S31 and _S32 to resume operation. As a result, even if the trains _T1 and _T2 are temporarily stopped because the observed seismic motions _GA and _GB exceed the stop reference value _Th1 , for example, when the trackside earthquake motion _GD falls below the inspection reference value _Th2 , the trains _T1 and _T2 can be immediately moved to station α without safety confirmation by a staff member.

In S730, the operation restart permission unit 8e does not permit the train _T4 to resume operation. For example, as shown in FIG. 3B, between the stop position _P4 and station β, there are some sections where the trackside earthquake motion _GD is below the inspection standard value _Th2 , but there are also sections where the trackside earthquake motion _GD exceeds the inspection standard value _Th2 . Between the stop position _P4 and station β, there is a movable section _S33 where the train _T4 can be moved without carrying out a trackside inspection after the occurrence of an earthquake, but there is also an inspection section _S21 where inspection is required after the occurrence of an earthquake, and the train _T4 cannot be moved from the stop position _P4 to station β. For this reason, the operation restart permission unit 8e does not permit the train _T4 to resume operation for the train _T4 that is stopped outside the movable range _S33 where the trackside earthquake motion _GD exceeds the inspection standard value _Th2 . As a result, the train _T4 remains stopped at the stop position _P4 until the safety of the railway facility is confirmed by the staff.

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, when the trains _T1 , _T2 stop in the movable sections _S31 , _S32 where the trackside seismic motion _GD is below the inspection standard value _Th2 , the operation restart permission unit 8e permits the trains _T1 , _T2 to resume operation to another stop position _Pα within the movable sections _S31 , _S32 . Therefore, the trains _T1 , _T2 can be moved from the stop positions _P1 , _P2 to the other stop position _Pα . As a result, the trains _T1 , _T2 that stopped when the earthquake occurred can be quickly resumed operation from the stop positions _P1 , _P2 .

(2) In this embodiment, the operation restart permission unit 8e permits the trains T1, T2 to resume operation to another stop position _Pα within the movable sections _S31 , _S32 where the trackside seismic motion _GD is lower than the inspection reference value _Th2 , which is the criterion for whether or not a trackside inspection is necessary after the occurrence of an earthquake. This allows _the trains _T1 , _{T2 that} are stopped during an earthquake to run quickly from the stop positions _P1 , _P2 . As a result, the trains stopped during an earthquake can resume operation early.

(3) In this embodiment, the operation restart permission unit 8e permits the trains _T1 and _T2 to resume operation up to station α in the movable sections _S31 and _S32 where the trackside earthquake motion _GD is below the inspection standard value _Th2 . For this reason, for example, the trains _T1 and _T2 stopped between stations during an earthquake can be made to travel at the slowest possible speed to the next station α, and passengers can be made to disembark from the trains _T1 and _T2 at station α quickly. As a result, trains stopped between stations during an earthquake can be quickly restarted, and passengers can be quickly rescued.

(4) In this embodiment, the operation restart permission unit 8e permits the trains T ₁ and T ₂ to resume operation to another stop position P α in the movable sections S ₃₁ and S ₃₂ where the lineside earthquake motion G _D is below the inspection standard value Th ₂ based on the lineside earthquake motion information output by the lineside earthquake motion evaluation system ₅ that evaluates the lineside earthquake motion G _D and the position information of the trains T ₁ to T ₄ output by the traffic control system 6 that manages the operation of the trains T ₁ to T _4. For this reason, for example, when it is confirmed by referring to detailed lineside earthquake motion information that the earthquake motion between the stop positions P ₁ and P ₂ of the trains T ₁ and T ₂ and the next station α does not reach the inspection implementation standard value, the trains T ₁ and T ₂ can be made to run at the slowest speed to the next station α. As a result, it is possible to support the resumption of operation after an earthquake in railways. In addition, the scope of use can be further expanded by adding an operation restart support function to railway operators who have introduced the Railway Earthquake Damage Estimation Information Distribution System (DISER). Furthermore, by successively updating trackside seismic motion information after an earthquake occurs, it is possible to provide information that supports early resumption of operation of trains T ₁ , T ₂ , T ₄ from stopping positions P ₁ , P ₂ , P ₄ .

(5) In this embodiment, the railway line earthquake motion evaluation system 5 evaluates the earthquake motion along the railway line based on observed earthquake motion information related to 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, it is possible to observe the earthquake motion along the railway line with high accuracy and easily grasp the railway line earthquake motion information.

(6) In this embodiment, the railway line earthquake motion evaluation system 5 evaluates the railway line earthquake motion based on the observed earthquake motion information on the earthquake motion at each observation point observed by the seismometers M _A to M _C. Therefore, it is possible to estimate the planar earthquake motion distribution by spatial interpolation using only the observed earthquake motion by the seismometers of public institutions such as K-NET output by the external earthquake observation system 3, and then extract the railway line earthquake motion G _D to generate railway line earthquake motion information. In addition, it is possible to estimate the planar earthquake motion distribution by spatial interpolation using both the observed earthquake motions G _A to G _C output by the company's earthquake disaster prevention system 2 and the observed earthquake motion output by the external earthquake observation system 3, and then extract the railway line earthquake motion G _D to generate railway line earthquake motion information.

(7) In this embodiment, the resumption of operation of the trains _T1 and _T2 is notified to the dispatcher by the operation resumption notification device 11. Therefore, the dispatcher can inform the drivers of the trains _T1 and _T2 of the resumption of operation by train radio or the like, and the trains _T1 and _T2 can be moved to a safe stopping position _Pα at the slowest possible speed.

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 T ₁ to T ₄ are railroad vehicles such as bullet trains or conventional railroads, but the present invention can be applied to other moving bodies such as magnetic levitation railroad vehicles, monorail vehicles, guide rail vehicles (new transit systems), and automobiles. In addition, in this embodiment, the stations α and β used to check passenger status as stations are used as stations, but the present invention can be applied to stations such as freight stations used to load and unload cargo, signal stations used to allow trains to pass or wait, and shunting yards used to switch vehicles and form trains. Furthermore, in this embodiment, the trains T ₁ and T ₂ stopped between stations are allowed to resume operation up to another stop position P _α in the movable ranges S ₃₁ and S ₃₂ , but the present invention is not limited to the case of moving the trains T ₁ and T ₂ to the station α. For example, the present invention can be applied to a case where a train stopped within a movable range in a railroad crossing, in a tunnel, or on a bridge is moved to another stop position outside the railroad crossing, outside the tunnel, or outside the bridge within the movable range. In this case, for example, when a train is stopped straddling a railroad crossing, the crossing gate can be raised by moving the train within the movable range outside the railroad crossing. Similarly, in this embodiment, an example has been described in which trains _T1 and _T2 stopped at stop positions _P1 and _P2 are permitted to resume operation up to the nearest station α within the movable ranges _S31 and _S32 , but the present invention can also be applied to a case in which trains are permitted to resume operation up to a station other than the next station α as long as it is within the movable range.

(2) In this embodiment, the case where observed seismic motion information output by the earthquake disaster prevention system 2, the earthquake observation system 3, and the high-density earthquake observation system 4 is used has been described as an example, but the present invention can also be applied to a case where observed seismic motion information obtained by any one of these or any combination of these is used. In addition, in this embodiment, the case where the high-density earthquake observation system 4 observes seismic motion along the railway line at high density using distributed acoustic measurement has been described as an example, but the present invention is not limited to observation using distributed acoustic measurement. For example, by arranging many seismometers at high density on the railway line R, seismic motion along the railway line can be observed in detail. Furthermore, in this embodiment, the case where three seismometers M _A to M _C are installed along the railway line has been described as an example, but the number of seismometers installed is not limited to three, and the present invention can also be applied to a case where two or less or four or more seismometers are installed.

(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 portable terminal carried by the driver of the trains T1 and T2. Also, 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 and 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.
