Description

The present invention provides an operation resumption determination device for determining whether or not operation can be resumed from the stop position of a moving body that stopped when an earthquake occurred, and an operation restart that supports early resumption of operation from the stop position of a moving body that stopped when an earthquake occurred. Regarding support systems.

In the event of an earthquake, if the conditions for stopping trains are met, trains in operation will be immediately stopped in an emergency by the early earthquake warning system. After that, if the seismic motion observed by the seismographs installed at regular intervals by the railway operator exceeds the predetermined reference value, operation restrictions such as slowing down and inspection will be implemented. Conventional earthquake early detection and warning systems consist of sensors that detect seismic motion at multiple detection points, and a control processing device that estimates the damage area based on seismic motion information detected by each sensor and issues an alarm as necessary. (see, for example, Patent Document 1). In this conventional earthquake early detection and warning system, the presence or absence of harmfulness is determined based on seismic motion information. ing.

The Damage Information System for Earthquake on Railway (DISER) (registered trademark) has been developed with the aim of providing information to support the early resumption of train operations. It is possible to obtain the distribution of seismic ground motion, detailed estimation information of seismic ground motion along registered routes, and estimated damage rank information of railway structures. This railway earthquake damage estimation information distribution system uses public earthquake information released immediately after an earthquake and a ground database to estimate the planar seismic motion distribution. The damage rank is estimated, and the estimated information is delivered immediately to railway operators (for example, see Non-Patent Document 1). This railway earthquake damage estimation information distribution system quickly resumes train operation based on the estimated information.

When a large earthquake is detected by a seismometer along a railway line and the observed seismic motion exceeds a predetermined reference value, trains in operation are immediately stopped in an emergency. After that, staff visually inspect the condition of railway facilities such as structures along the line, and after confirming safety, train operation is resumed. However, since inspections are carried out by humans on foot, the work takes a long time, and train operation cannot be resumed until all inspections, etc., are completed and safety is confirmed. As a result, it takes a long time to eliminate trains that are stopped between stations and to save passengers, which is one of the factors that make it difficult to resume operations early.

BEST MODE FOR CARRYING OUT THE INVENTION Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.
A track R shown in FIG. 2 is a passage (track) on which trains T ₁ to T ₄ run. The track R is a double track composed of two main lines, a down line R ₁ on which down trains T ₁ and T ₃ run from the starting point to the end point, and an up train T ₂ and T from the end point to the starting point. It consists of an inbound line R ₂ on which ₃ runs. 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 running on Shinkansen (registered trademark) or conventional line trains running on conventional lines. The trains T ₁ to T ₄ are rail vehicles such as electric cars or internal combustion cars (internal combustion cars), and are composed and organized by one or more rail cars.

The operation resumption support system 1 shown in FIGS. 1 and 2 is a system that supports early operation resumption from the stopping positions P ₁ , P ₂ , and P ₄ of the trains T ₁ , T ₂ , and T ₄ that stopped at the time of the earthquake. . Based on the observed seismic motion information observed immediately after the earthquake, the operation resumption support system 1 evaluates the planar seismic motion distribution and the linear seismic motion distribution along the track R on which the trains T ₁ to T ₄ run. Stop positions P ₁ , P ₂ , T ₄ of the trains T 1 , T _{2 , T 4 are determined based on the stop positions P 1 , P 2 , P 4} of the stopped trains T ₁ , T ₂ , _{T 4} and the seismic motion along the track _GD . Judgment is made as to whether or not early operation can be resumed from _P4 . The operation resumption support system 1 is, for example, a support system for early cancellation of stopped trains between stations that supports the resumption of operation of stopped trains between stations after an earthquake in order to cancel stopped trains between stations early. The operation resumption support system 1 includes the earthquake disaster prevention system 2 shown in FIGS. 1 and 2, the operation information display device 10 shown in FIG. 2, the operation resumption notification device 11, and the like.

The earthquake disaster prevention system 2 shown in FIGS. 1 and 2 is a system that observes the seismic motion at each observation point by seismometers M _A to M _C shown in FIG. Here, seismic motion is ground shaking motion in an earthquake. Indices of seismic motion used for train operation control during an earthquake are maximum acceleration for warning, spectral intensity (SI value), instrumental seismic intensity, maximum acceleration (Peak Ground Acceleration (PGA)), and maximum velocity (Peak Ground Velocity (PGV)), which is the maximum amplitude value (absolute value) of velocity recording. The earthquake disaster prevention system 2 is, for example, an early earthquake warning system that estimates earthquake specifications based on initial microtremor data for several seconds of seismic motion and controls operation. The earthquake disaster prevention system 2 includes seismometers for early warning that are installed at each observation point to measure and record seismic motion, a relay server that relays seismic motion information between seismographs and that transmits and manages the seismic motion information. It is equipped with monitoring terminals for monitoring seismometers and relay servers. The earthquake disaster prevention system 2, for example, observes relatively sparse seismic motions using seismometers installed by the railway operator at each observation point along the railway line. The earthquake disaster prevention system 2 can also use, for example, the observed seismic motion information output by the earthquake observation system 3 . The _{earthquake disaster prevention} system 2 detects seismic motions at respective observation points as shown in FIGS _. The earthquake disaster prevention system 2 outputs the observed seismic motions G A _to G _C observed by the seismographs M _A to M _C at each observation point to the trackside seismic motion evaluation system 5 and the operation resumption determination device 8 as observed seismic motion information.

The earthquake disaster prevention system 2 shown in FIGS. 1 and 2 determines whether or not the trains T ₁ to T ₄ running on the track R should be stopped in an emergency when an earthquake occurs. As shown in FIGS. 3(A) and 3(B), the earthquake disaster prevention system 2 allows trains T ₁ , T ₂ , and T ₄ to pass through the stop section S ₁ where the observed seismic ground motions G _A and _GB exceed the stop reference value Th ₁ . When running, it is determined that the trains T ₁ , T ₂ and T ₄ running in this stop section S ₁ need to be stopped urgently. On the other hand, when the train T3 is running outside the stop section _{S1 where} the observed seismic motion G _C is lower than the stop reference value _Th1 , the earthquake disaster prevention system 2 makes an emergency warning for the train _T3 running outside the stop section _S1 . It is determined that there is no need to stop. Here, the stop reference value Th ₁ shown in FIG. 3B is a reference value when determining whether or not it is necessary to stop the trains T ₁ to T ₄ after an earthquake occurs. A stop section _S1 shown in FIGS. 3B and 3C is a section in which the trains _T1 , _T2 , and _T4 must be stopped after an earthquake occurs. A boundary AB is a boundary between a section in charge of seismometer M _A and a section in charge of seismometer M _B . A boundary BC is a boundary between a section in charge of the seismometer M _B and a section in charge of the seismometer M _C . The earthquake disaster prevention system 2 automatically stops the electric power supplied to the trains T1 _to T4 and brakes the trains _T1 to _T4 automatically when _it is necessary to stop the trains _T1 to _T4 in an emergency when an earthquake occurs. or instruct the drivers of trains T ₁ to T ₄ to make an emergency stop by train radio.

The earthquake observation system 3 differs from the seismometers M _A to M _C in-house used in the earthquake disaster prevention system 2 for seismic motion observation. The seismic motion is observed by a seismometer installed at the observation point. The earthquake observation system 3 receives, for example, seismic motion information (Earthquake Early Warning) from seismometers at each observation point of the Japan Meteorological Agency, or seismic motion information from the strong motion observation network (Kyoshin Network (K-NET)) of the National Research Institute for Earth Science and Disaster Resilience. Use information (K-NET observation data), etc. The earthquake observation system 3 outputs the observed seismic motions observed by the seismographs at each observation point to the trackside seismic motion evaluation system 5 as observed seismic motion information (seismic motion information).

The high-density seismic observation system 4 is a system for high-density observation of seismic motions along railway lines. The high-density seismic observation system 4 uses, for example, an optical fiber cable as a sensor to perform distributed acoustic sensing (DAS), which measures distributed strain. . The high-density seismic observation system 4 can use, for example, an existing optical fiber cable for communication, and continuously and at high density measure seismic motion along the railway line using the optical fiber cable and the distributed sound measuring instrument. The high-density seismic observation system 4 pulsed optical signals and continuously transmits them from one end of the optical fiber cable, and the reflected signals (backscattered waves (Rayleigh scattered waves)) reflected from minute impurities in the optical fiber cable are collected. It includes an optical signal transmitter/receiver for receiving and an analysis unit for analyzing the reflected signal received by the optical signal transmitter/receiver. The high-density seismic 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 normally, and detects strain (deformation) of the optical fiber cable. to observe seismic motion. The high-density seismic observation system 4 can measure strain every several meters by using optical fiber cables of several tens of kilometers. Dense observation can be realized at low cost. The high-density earthquake observation system 4 outputs the high-density observed seismic motion observed along the railroad to the railroad seismic motion evaluation system 5 as observed seismic motion information.

The trackside earthquake motion evaluation system 5 shown in FIGS. 1 and 2 is a system for evaluating trackside earthquake motions. The trackside seismic motion evaluation system 5 evaluates the trackside seismic motion based on the observed seismic motion information output by the earthquake disaster prevention system 2 and the earthquake observation system 3 . As shown in FIG. 1, the trackside seismic motion evaluation system 5 estimates the trackside seismic motion along the track R based on the observed seismic motion information of each observation point output by the earthquake observation system 3, and the earthquake disaster prevention system 2 and Based on the observed seismic motion information of each observation point output by the seismic observation system 3, the seismic motion along the track R is estimated. The earthquake ground motion evaluation system along railway lines 5 considers the changes in ground characteristics when strong earthquake motions act, and based on the ground motion information along railway lines and the observed seismic motion information immediately after the earthquake, evaluates the distribution of planar seismic motion and the distribution of linear earthquake ground motion along railway lines. presume. Based on the observed seismic motion information of each observation point, the evaluation system for seismic motion along the railway line 5 estimates the input seismic motion of the bedrock considering the amplification characteristics of the ground, performs spatial interpolation using the estimated input seismic motion of the bedrock, 500m-mesh planar seismic ground motion distribution is calculated. Here, spatial interpolation is a technique used when predicting peripheral data using known data such as observed values. The trackside seismic motion evaluation system 5 uses the ground amplification characteristics of each mesh to calculate the planar seismic motion distribution of the ground surface and the lineal seismic motion distribution along the track. The railway earthquake motion evaluation system 5 is, for example, a railway earthquake damage estimation information distribution system that estimates the earthquake motion along railway lines and the damage rank of railway structures immediately after an earthquake in order to support proper judgment of the inspection range after an earthquake.

The trackside seismic motion evaluation system 5 evaluates the trackside seismic motion based on the observed seismic motion information regarding the high-density seismic motion along the track observed by distributed acoustic measurement, for example. The trackside seismic motion evaluation system 5 evaluates the trackside seismic motion along the track R based on the observed seismic motion information output by the high-density seismic observation system 4, as shown in FIG. The evaluation system for seismic motion along the railway line 5 estimates the seismic motion distribution along the railway line by spatially interpolating the observed seismic motion information output only by the earthquake observation system 3 and the observed seismic motion information output by the earthquake disaster prevention system 2 and the earthquake observation system 3. In contrast, the seismic motion distribution along the line is generated from the observed seismic motion information output by the high-density seismic observation system 4 .

The evaluation system for earthquake ground motion along the railway line 5 extracts the earthquake ground motion along the railway line G _D 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, A) and along-line seismic motion information is generated by associating the along-line seismic motion G _D with the kilometerage as shown in FIG.

Here, the kilometerage shown in FIGS. 1A, 1B and 3 is the extension (distance) of the line R from the starting point, and is generally set to ascend from the starting point toward the terminal point. _The trackside _seismic motion evaluation system 5, for example, as shown in _FIG . As shown in Figs. 1(C) and 3(B), the evaluation system for earthquake ground motion along the railway line 5, when the vertical axis is the seismic motion and the horizontal axis is the kilometer scale, evaluates the railway track seismic motion _GD corresponding to the kilometer scale.

The operation management system 6 is a system that supports operations for smooth operation of the trains T ₁ to T ₄ . The operation control system 6 is, for example, a train operation control system (Programmed Traffic Control (PTC)) that centrally manages and controls trains T ₁ to T ₄ based on train schedules in railway train operation control. For example, as shown in FIG. 3A, the operation management system 6 detects the stop position _P1 of the train T1 that stopped on the outbound line _R1 when the earthquake occurred, and also detects the stop position P1 of the train _T1 that stopped on the inbound line _R2 when the earthquake occurred. Stop positions P ₂ and P ₄ of the trains T ₂ and T ₄ which have stopped are detected. The operation management system 6 always grasps the operation status of the trains T ₁ to T ₄ and detects the running position P ₃ and the stop positions P ₁ , _{P 2 and} P ₄ of the trains T ₁ to T 4 on the track R. Then, the current positions of the trains T ₁ to T ₄ are output to the operation resumption determination device 8 and the operation information display device 10 as position information (track position information).

The operation command center 9 is a field organization in which a commander who performs command work in the operation command center 9 is engaged _. Tasks such as monitoring the operation status of trains T ₁ to T ₄ are performed by dispatchers. The operation command center 9, for example, instructs the drivers of _the trains T1 _and T2 to restart the operation of the trains _T1 and _T2 from the stop positions _P1 and _P2 to the next station α at slow speed. By, the commander gives work instructions. The operation command center 9 includes an operation information display device 10, an operation resumption notification device 11, and the like.

The operation information display device 10 shown in FIGS. 2 and 4 is a device for displaying the operation status of trains T ₁ to T ₄ . The operation information display device 10 displays on the screen operation information managed by the operation management system 6, such as the current positions (on-track positions) of the trains T ₁ to T ₄ , train numbers of the trains T ₁ to T ₄ , destinations, and delay times. indicate. _The operation information _display device _{10 , as shown} in _{FIG .} indicate.

The operation resumption notification device 11 notifies the commander of the determination result of the operation resumption determination device 8 . Upon receiving the operation resumption information transmitted by the operation resumption determination device 8, the operation resumption notification device 11 makes the commander in the operation command center 9 notify the operation resumption visually or aurally. The operation resumption notification device 11 displays, for example, the trains T ₁ and T ₂ permitted to resume operation shown in FIG. The commander in the operation command center 9 is notified by the voice generated by the voice generator.

Next, the operation of the operation resumption support system according to the embodiment of this 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 earthquake disaster prevention system 2 sends the observed seismic motions G _A to G _C at each observation point measured by the seismometers M _A to M _C shown in FIGS. It is transmitted to the restart 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 railway line earthquake motion evaluation system 5, and high-density observed seismic motion at each observation point continuously measured along the railway line is transmitted from the high-density seismic observation system 4 to the trackside seismic motion evaluation system 5 .

In S200, the earthquake disaster prevention system 2 determines whether or not the observed seismic motions G _A to G _C exceed the stop reference value _Th1 . When the earthquake disaster prevention system 2 judges that the observed seismic motions G _A to G _C exceed the stop reference value _Th1 , the process proceeds to S300, and the earthquake disaster prevention system ₂ judges that the observed seismic motions G _A to G _C are below the stop reference value Th1. If so, the process proceeds to S400.

In S300, the earthquake disaster prevention system 2 makes the trains _T1 , _T2 , and _T4 stop urgently. As shown in FIG. 3(B), when the trains _T1 , _T2 , _T4 are in the stop section _S1 in which the observed seismic ground motions G _A and _GB exceed the stop reference value _Th1 , this stop section _S1 The earthquake disaster prevention system 2 makes an emergency stop of the trains _T1 , _T2 , and _T4 that are on the track.

At S400, the earthquake disaster prevention system 2 does not bring the train _T3 to an emergency stop. As shown in FIG. 3(B), when the train T3 is located outside the stop section _{S1 where the observed seismic ground motion G C is lower than the stop reference value Th1 , the train T3} located outside the stop section _S1 is not brought to an emergency stop by the earthquake disaster prevention system 2.

In S500, the trackside seismic motion evaluation system 5 evaluates the trackside seismic motion. When the trackside earthquake motion evaluation system 5 receives the observed seismic motion information from the earthquake disaster prevention system 2 or the earthquake observation system 3, as shown in FIGS. 1(C) and 3(B), the trackside seismic motion G _D is estimated by the trackside seismic motion evaluation system 5. In addition, when the trackside seismic motion evaluation system 5 receives the observed seismic motion information _from the high-density seismic observation system 4, as shown in Figs. The trackside seismic motion evaluation system 5 evaluates. As a result, the trackside seismic motion evaluation system 5 transmits the trackside seismic motion G _D to the operation resumption determination device 8 as trackside seismic motion information.

At S600, the operation management system 6 detects the positions of the trains T ₁ to T ₄ . For example, as shown in FIGS. 3A and 3B, the operation management system 6 detects the stop positions P ₁ , P ₂ and P ₄ of the trains T ₁ , T ₂ and T ₄ , and the trains T ₁ and T The operation management system 6 transmits the position information of ₂ and T ₄ to the operation resumption determination device 8 . Further, for example, the operation management system 6 detects the running position _P3 of the train _T3 located outside the stop section _S1 , and the operation management system 6 transmits the position information of the train _T3 to the operation resumption determination device 8. .

In S700, the operation resumption determination device 8 executes operation resumption determination processing for determining whether operation of the trains _T1 , _T2 , and _T4 can be resumed. First, the operation restart determination device 8 determines whether or not the trains T ₁ to T ₄ are in the stop section S ₁ where the trackside seismic motion G _D exceeds the stop reference value Th ₁ , and stops within the stop section S ₁ . The trains T ₁ , T ₂ , and T ₄ that are running are specified by the operation resumption determination device 8 . Next, as shown in FIGS. 3A and 3B, trains T ₁ , T ₂ and T ₄ that stopped at stop positions P ₁ , P ₂ and P ₄ when the earthquake occurred are transferred to stop positions P ₁ and P _{2 .} , _P4 .

At S800, the operation resumption notification device 11 notifies the dispatcher of the resumption of operation of the trains _T1 and _T2 . When the dispatcher in the operation control center 9 instructs the drivers of the trains T1 _{and T2} to restart the operation of the trains _T1 and T2 by train radio or the like, the drivers of the trains _T1 and _T2 instruct the trains T1 _{and T2} to resume operation. T ₂ is restarted at the slowest speed from the stop positions P ₁ and P ₂ . As a result, trains T ₁ and T ₂ move to station α within movable sections S ₃₁ and S ₃₂ , and passengers on trains T ₁ and T ₂ get off at station α.

Next, the operation of the operation resumption determination device according to the embodiment of this invention will be described.
The operation of the operation resumption permitting section 8e shown in FIG. 4 will be mainly described below.
In S710 shown in FIG. 6, the operation resumption permitting unit 8e determines whether or not the wayside seismic motion _GD is below the inspection reference value _Th2 . As shown in FIG. 3, the operation resumption permitting unit determines whether or not the trains T ₁ , T ₂ , T ₄ are stopped within the movable range S ₃₁ to S ₃₃ where the trackside seismic motion _GD is lower than the inspection reference value Th ₂ . 8e decides. When the operation resumption permitting unit 8e _determines that _{the trackside seismic motion GD is} below the inspection reference value _Th2 , the process proceeds to S720. move on.

At S720, the operation resumption permission section 8e permits the operation resumption of the trains _T1 and _T2 . In the conventional earthquake early warning system, it is assumed that the observed seismic ground motion G _B observed by the seismometer M _B that divides between Boundary AB and Boundary B-C shown in Fig. 3(B) is constant between them. In order to make a judgment, it is judged that the observed seismic ground motion G _B exceeds the inspection reference value _Th2 . Therefore, in the conventional early warning system, the train T ₁ stopped at the stop position P ₁ 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 trackside seismic motion G _D can be evaluated in detail at each position on the track R compared to the conventional early earthquake warning system. Therefore, in this embodiment, the train _T2 cannot _{be moved from the stop position P2 in the section where the trackside seismic motion G D exceeds the inspection} standard value _Th2. It is possible to move train _T2 for the section below . For example, as shown in FIG. 3(B), from the stop position _P2 to the station α, since the trackside seismic motion G _D is continuously below the inspection reference value _Th2 , from the stop position _P2 to the station α It is possible to move the train _T2 to Therefore, for the trains T ₁ and T ₂ stopped within the movable ranges S ₃₁ and S ₃₂ where the trackside seismic motion _GD is lower than the inspection reference value Th ₂ , the train T within the movable ranges S ₃₁ and S _{32 1} and _T2 are allowed to resume operation by the operation resumption permitting unit 8e. As a result, for example, even if the trains _T1 and _T2 are temporarily stopped because the observed seismic motions G _A and _GB exceed the stop reference value _Th1 , when the wayside seismic motion G _D falls below the inspection reference value _Th2 , the trains T ₁ and T ₂ can be immediately moved to the α station without safety confirmation by the staff.

At S730, the operation resumption permission section 8e does not permit the operation resumption of the train _T4 . For example, as shown in FIG. 3(B), from the stop position _P4 to the station β, there is a section where the trackside seismic motion _GD is lower than the inspection reference value _Th2 , but the trackside seismic motion _GD There are sections that exceed the inspection reference value _Th2 . Between the stop position _P4 and the station β, there is a movable section _S33 in which the train _T4 can be moved without inspecting the track after the earthquake. The required inspection section _S21 also exists, and the train _T4 cannot be moved from the stop position _P4 to the station β. Therefore, the operation resumption permission unit 8e does not permit the operation resumption of _the train _T4 , which is stopped outside the movable range _S33 where the trackside seismic motion G _D exceeds the inspection reference value _Th2 . As a result, the train _T4 remains stopped at the stop position _P4 until the staff confirms the safety of the railway facility.

The operation resumption determination device and the operation resumption support system according to the embodiments of the present invention have the following effects.
(1) In this embodiment, when the trains _T1 and _T2 stop in the movable sections _S31 and _S32 where the trackside seismic ground motion _GD is lower than the inspection reference value _Th2 , the movable sections _S31 and S The operation resumption permitting unit 8e permits operation resumption of the trains T ₁ and T ₂ up to another stop position P _α within ₃₂ . Therefore, the trains T ₁ and T ₂ can be moved from the stop positions P ₁ and P ₂ to another stop position P _α . As a result, the trains T ₁ and T ₂ that stopped when the earthquake occurred can be quickly restarted from the stopping positions P ₁ and P ₂ .

(2) In this embodiment, the movable sections S 31 and S 32 are movable sections S ₃₁ and S ₃₂ in which the earthquake ground motion along the railroad track _GD is lower than the inspection reference value Th ₂ that determines whether or not it is necessary to inspect the railroad track after the occurrence of an earthquake. The operation resumption permitting unit 8e permits operation resumption of the trains _T1 and _T2 up to another stop position _Pα . Therefore, the trains T ₁ and T ₂ stopped at the time of the earthquake can be made to run quickly from the stop positions P ₁ and P ₂ . As a result, it is possible to quickly resume operation of trains that were stopped at the time of the earthquake.

(3) In this embodiment, the operation resumption permission unit 8e permits the operation resumption of the trains _{T1 and T2} up to the station α in the movable sections _S31 and _S32 where the seismic ground motion _GD along the track is lower than the inspection reference value Th2. do. Therefore, for example, trains T ₁ and T ₂ stopped between stations at the time of an earthquake can be run at the slowest speed to the next station α, and passengers can be quickly transported from trains T ₁ and T ₂ to station α. can be dropped off. As a result, trains stopped between stations at the time of an earthquake can be resumed at an early stage, and passengers can be relieved at an early stage.

(4) In this embodiment, the trackside seismic motion information output by the trackside seismic motion evaluation system 5 for evaluating the trackside seismic motion G _D and the train T ₁ to T ₄ output by the operation management system 6 for managing the operation of the trains T _{1 to T 4} Based on the position information of _T4 , the operation of trains _T1 and _T2 is resumed to another stop position _Pα in the movable sections _S31 and _S32 where the trackside seismic motion _GD is lower than the inspection reference value _Th2 . The restart permitting unit 8e permits. For this reason, for example, referring to the detailed earthquake motion information along the railway line, it is determined 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 reference value. can be confirmed, the trains T ₁ and T ₂ can be run at the slowest speed to the next station α. As a result, it is possible to support the resumption of operation of railways after an earthquake. In addition, for railway operators that have introduced the Railway Earthquake Damage Estimation Information Distribution System (DISER), the range of utilization can be further expanded by adding an operation resumption support function. Further, it is possible to sequentially update the information on seismic ground motion along railway lines after the occurrence of an earthquake, and to provide information that supports early resumption of operation of trains _T1 , _T2 , and _T4 from stop positions _P1 , _P2 , and _P4 . can.

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

(6) In this embodiment, the trackside seismic motion evaluation system 5 evaluates the trackside seismic motion based on the observed seismic motion information on the seismic motion at each observation point observed by the seismometers M _A to M _C . For this reason, after estimating the planar seismic motion distribution by spatial interpolation using only the seismic motion observed by seismometers of public institutions such as K-NET output by the external seismic observation system 3, the seismic motion along the line G _D is extracted. can generate earthquake ground motion information along the railway line. In addition, after estimating the planar seismic motion distribution by spatial interpolation using both the observed seismic motions G _A to G _C output by the company's own earthquake disaster prevention system 2 and the observed seismic motions output by the external earthquake observation system 3, By extracting G _D , it is possible to generate trackside seismic ground motion information.

(7) In this embodiment, the operation resumption notification device 11 notifies the dispatcher of the operation resumption of the trains T ₁ and T ₂ . Therefore, the dispatcher can inform the drivers of the trains T ₁ and T ₂ that the trains T 1 and T 2 have resumed operation by train radio or the like, and the trains T ₁ and T ₂ can be moved slowly to the safe stop position _Pα . can.

The present invention can also be applied to other moving bodies such as a vehicle, a guide rail type (new transportation system) vehicle, or an automobile. In addition, in this embodiment, the stations α and β used as stops to check the status of passengers have been described as examples, but freight stations used for loading and unloading cargo, crossing trains, or The present invention can also be applied to a signal field used for waiting, and a stop such as a shunting yard used for changing cars or composing trains. Furthermore, in this embodiment, the case where the trains T ₁ and T ₂ stopped between stations are permitted to resume operation up to another stop position P _α in the movable ranges S ₃₁ and S ₃₂ has been described as an example. However, the present invention is not limited to moving trains T ₁ and T ₂ to station α. For example, when moving a train that is stopped within the movable range of a railroad crossing, tunnel or bridge to another stop position outside the railroad crossing, tunnel or bridge within the movable range, this also applies. The invention can be applied. In this case, for example, when the train is stopped so as to straddle the railroad crossing, the railroad crossing barrier can be raised by moving the train into the movable range outside the railroad crossing. Similarly, in this embodiment, the trains T ₁ and T ₂ stopped at the stop positions P ₁ and P ₂ are allowed to resume operation up to the nearest station α in the movable ranges S ₃₁ and S ₃₂ as an example. As described above, the present invention can also be applied to the case where operation resumption is permitted to stations other than the next station α as long as it is within the movable range.

The present invention can also be applied to the case of using arbitrarily combined observed seismic ground motion information. In this embodiment, the high-density seismic observation system 4 performs high-density observation of seismic motion along railway lines by distributed acoustic measurement. However, the present invention is limited to observation by distributed acoustic measurement. not a thing For example, by arranging a large number of seismometers on the railway line R at a high density, it is possible to observe seismic motion along the railway line in detail. Furthermore, in this embodiment, the case where three seismometers M _A to M _C are installed along the railway has been described as an example, but the number of installed seismometers is not limited to three. The present invention can also be applied when four or more units are installed.

₍ 3) In this embodiment, the case where the dispatcher of the operation control center 9 wirelessly communicates to the drivers of the trains _T1 and _T2 to resume operation has been described _. The present invention can also be applied to a case where a mobile terminal carried by a driver is notified of the resumption of driving. Further, in this embodiment, the case where the drivers of the trains T ₁ and T ₂ notified by the dispatcher of the operation command center 9 restart the operation from the stop positions P ₁ and P ₂ has been described as an example. The present invention is not limited to such an operation resuming method. For example, when trains _T1 and _T2 are automatically restarted from stop positions _{P1 and P2} by an automatic train operation (ATO) system for automatically operating trains T1 to _T4 . can also apply this invention.
