Description

  The present invention relates to a method for automatically changing a vehicle speed regulation reference value that complements a disturbing seismometer, and supplements the disturbing seismometer in the event of a seismometer failure or local power failure in the seismometer network. The present invention relates to a method for automatically changing the speed regulation reference value of a vehicle traveling in an area.

  Conventionally, when an earthquake occurs, in railways, etc., depending on the magnitude of the seismic motion recorded by the seismometers installed linearly on the side of the track, railway vehicle speed regulation (slow down) and operation stop (stop) Operational regulation is performed.

  FIG. 2 is a schematic diagram modeling the positional relationship between the earthquake detection point of the railway where the seismometer is installed and the epicenter of the earthquake.

  In this figure, the distance xkm between the earthquake detection points of the railway is, for example, 20 km. The reference value for speed regulation is to miss the lower limit of ground motion that the railway suffered in the past, assuming that it is the maximum ground motion at the center between the seismic detection points (distance x / 2 km from either detection point) It is necessary to set so that there is no.

In this figure, Δ _k = √ [Δ ² ₁₈ + (x / 2) ² ].

3 shows that the SI value at the detection point position is set to a magnitude when the SI value as the operation stop criterion of the operating vehicle is set to 18 kine since the lower limit SI value at which the railway has been damaged in the past is about 18 kine. FIG. In FIG. 3, a indicates the lower limit magnitude at which the railway was damaged. The SI value at the detection point position can be obtained by using a distance attenuation formula. Here, log (SI) = 0.5324 · M−0.0017 · Δ−0.6501 is used as the distance attenuation formula of the SI value. -LogΔ-1.2441 was adopted. In FIG. 3, has a detection point interval as a parameter, ■ it is 5km the detection point interval, ● is the detection point interval 10 km, △ is 15km, ▼ is 20 km, ◇ shows the case of 40km respectively.

  Seismometers are positioned as important devices because they can be used to determine operations when an earthquake occurs. However, seismometers may be stopped locally or communicated when the seismometer itself fails or a power outage occurs. The seismometer information may not be transmitted to the operation manager due to disconnection of the line.

  In that case, in the seismometer network, operation control will be performed using information on seismometers installed on both sides of the disturbing seismometer, but the range covered by the seismometers on both sides is more than normal. Because it becomes wider, it is necessary to change the speed regulation reference value.

  In view of the above situation, the present invention automatically changes the speed regulation reference value described above by the central processing unit, so that even when an earthquake occurs during a seismometer failure or a local power failure, the vehicle travels. It is an object of the present invention to provide an automatic change method of a vehicle speed regulation reference value that complements a disturbing seismometer, and that can ensure safety.

In order to achieve the above object, the present invention provides

  According to the present invention, even if a seismometer failure or a local power failure occurs in the seismometer network, the vehicle automatically changes the speed regulation reference value of the vehicle traveling in the area of the seismometer network. It is possible to ensure the safety.

It is a schematic diagram explaining the concept regarding the automatic change of the speed regulation reference value of the vehicle which drive | works the area of the seismometer network at the time of the failure of the seismometer and the local power failure which shows the Example of this invention. It is the figure which modeled the positional relationship of the earthquake detection point of the railway in which the seismometer was installed, and the epicenter of the earthquake. It is a figure which shows SI value in both detection point positions for every detection point interval with respect to a magnitude | size when the SI value used as the driving | operation cancellation reference | standard of a driving | running | working vehicle is set to 18kine, and the earthquake motion occurs in the center position of a detection point. .

In the method for automatically changing the speed regulation reference value of a vehicle that complements a disturbing seismometer, the seismometers arranged on both sides of the disturbing seismometer in the event of a seismometer failure or local power failure within the seismometer network By expanding the distance between the seismometers arranged on both sides of the troubled seismometer and automatically resetting the speed regulation reference value from the seismometers arranged on the both troubled seismometers, Based on the measured values , the central processing unit, which is a relay server, connects the seismometers arranged on both sides of the enlarged seismometer with respect to the seismometers arranged on both sides of the troubled seismometer via a communication network. When the train handling information corresponding to the measured value corresponding to the distance is output, the speed regulation reference value of the vehicle traveling in the area of the seismometer network is automatically changed.

  Hereinafter, embodiments of the present invention will be described in detail.

  FIG. 1 is a schematic diagram illustrating a concept relating to automatic change of the speed regulation reference value of a vehicle traveling in an area of a seismometer network when a seismometer fails or a local power failure occurs according to an embodiment of the present invention.

  In this figure, A is a route located in the area of the seismometer network, and 1 to 4 are seismometers arranged in the area of the seismometer network, and are arranged on the route A every 20 km, for example. 5 is a communication network connected to the seismometers 1 to 4, and 6 is a central processing unit (relay server) connected to the communication network 5.

  Here, when all of the seismometers 1 to 4 are operating normally, if an earthquake occurs and the SI value of the seismometers 1 to 4 is 18 kine or more, the vehicle running in the range that the seismometer is responsible for is driven. A command is issued from the central processing unit (relay server) 6 to cancel. Further, when the number is 9 kines or more and less than 18 kines, a command is issued from the central processing unit (relay server) 6 so as to regulate the speed of a vehicle traveling in the range that the seismometer is responsible for.

  However, for example, if the seismometer 3 cannot transmit the SI value due to a failure or a local power failure, the central processing unit (relay server) 6 detects the trouble state via the communication network 5 and the seismometer 3 A command is issued from the central processing unit (relay server) 6 to the seismometers 2 and 4 so that the seismometers 2 and 4 located on both sides are in a troubled state, and the distance between the seismometers 2 and 4 Is 40 km, the speed regulation reference value of the seismometers 2 and 4 is changed from 9 kine to 6 kine.

  As a basis for this, if one of the seismometers installed at intervals of 20 km fails, the seismometers on both sides of the disturbing seismometer are supplemented by the seismometer interval of 40 km. The lower limit magnitude at which the railway was damaged is set to 5.5. From FIG. 3, the SI value when the detection point interval is 20 km at a magnitude of 5.5 is about 9 kine. On the other hand, from FIG. 3, the SI value is about 6 kine when the magnitude is 5.5 and the detection point interval is 40 km. Therefore, when the installation interval of the seismometers is 20 km, the speed regulation reference value at normal time is 9 kine, and the speed regulation reference value of the seismometers on both sides of the trouble seismometer is 6 kine.

  Thus, when the seismometer 3 is in a troubled state, the seismometer 3 is complemented by automatically changing the speed regulation reference values of the seismometers 2 and 4 arranged on both sides thereof. Yes.

  In the above-described embodiment, the case where the seismometer is installed along the route on which the railway vehicle travels has been described. However, the present invention is applied to an automatic vehicle that installs a seismometer along the expressway and travels on the expressway. On the other hand, it can be applied to an example in which the speed regulation reference value is automatically changed.

  The seismic motion index that can be used by the vehicle speed regulation reference value automatic change method of the present invention can be applied not only to the SI value, but also to the maximum acceleration, maximum speed, measured seismic intensity, and the like.

  In addition, this invention is not limited to the said Example, Based on the meaning of this invention, a various deformation | transformation is possible and these are not excluded from the scope of the present invention.

  The automatic change method of the vehicle speed regulation reference value that complements the disturbing seismometer of the present invention enables the vehicle to run even when an earthquake occurs in the seismometer network at the time of a fault or a local power failure, It can be used to ensure safety.
