Description

  The present invention relates to a railway system that manages the remaining amount of resources necessary for train operation.

  Train operations require various resources, and trains must be operated within the limits of their supply. For example, since the amount of power supplied from a substation is finite, there is a limit to the number of trains that can be operated in one feeder section. Further, when using wireless communication for train control, the radio frequency band is also a resource, and there is a limit to the number of trains that can be operated in one wireless section.

  The train is usually operated according to a schedule determined in consideration of the limitation of the supply amount of resources. However, once the schedule is disrupted due to an accident, etc., the train must operate between the command station and each station such as a station, so if a communication error occurs, power shortages or radio frequency bands There is a concern that trains may stop between stations due to lack of trains. If a train stops between stations, passengers cannot even get off safely, which causes a major hindrance to safe train operation. Therefore, in such an emergency situation, there has been a demand for technical development of a railway system related to train operation in consideration of the supply amount of resources.

As a technique related to train operation in consideration of the amount of electric power, there is one disclosed in Patent Document 1, for example. However, this technique effectively uses electric power in one feeder section and efficiently performs train departure control, and is not effective for the above problem.
JP-A-9-76911

  An object of the present invention is to provide a railway system that can effectively contribute to safe train operation.

  In order to solve the above-described problem, the railway system according to the present invention includes a resource information holding unit and an analysis unit.

  The resource information holding unit holds route map information indicating a resource sharing section that shares resources when operating a train, and information on a supply amount of resources allocated to each resource sharing section.

  The analysis unit calculates a resource usage amount by identifying a train that is present for each resource sharing section from train position information and the route map information, and based on the usage amount and the supply amount, The remaining resource information including the remaining amount of resources for each resource sharing section is obtained.

  According to this railway system, the remaining amount is calculated by subtracting the usage amount from the resource supply amount for each resource sharing section, and further, for example, the number of trains that can be operated in the resource sharing section is also calculated from this remaining amount. can do.

  The remaining resource information obtained in this way can be effectively used for train operation management. That is, when the schedule is disturbed, it is possible to give a command to the train so that the train does not proceed to the resource sharing section where the remaining amount of the resource is small according to the remaining resource information. At this time, the train may be route-controlled or decelerated directly from the railway system, or the remaining resource information may be notified to a PRC (Programmed Route Control) device to cause the PRC device to control the train. . Of course, the remaining resource information may be simply displayed on a monitor or the like, and the person in charge of train operation may see this and give a command to the train.

  Therefore, according to the railway system according to the present invention, even when the schedule is disturbed, it is possible to prevent a situation in which the train is stopped between stations due to lack of resources.

  As described above, according to the present invention, it is possible to provide a railway system that can effectively contribute to safe train operation.

  FIG. 1 shows a railway system according to the present invention. The train operation management device 1 is installed at a command center and includes a resource information holding unit 11, an analysis unit 13, a train control unit 14, a notification unit 12, and a display unit 15. Each will be described below. Note that the notification unit 12 and the display unit 15 will be described as those according to other embodiments.

  The resource information holding unit 11 holds route map information K indicating a resource sharing section in which resources are shared when the train T is operated, and information on the supply amount S of resources allocated to each resource sharing section. The route map information K and the information on the supply amount S are output to the train control unit 14 and the analysis unit 13.

  The resource sharing section is a unit section for supplying resources. In the case of power resources, the feeding section corresponds, and in the case of radio resources, the wireless section corresponds. That is, in FIG. 1, the resource sharing section A and the resource sharing section B are supplied with power from different substations or assigned different radio frequency bands. Hereinafter, similarly, power resources or radio resources will be described as examples as resources, but the concept of resources is not limited to these.

  FIG. 2 is a route diagram showing a resource sharing section. Here, the solid line represents the track R, and the numbers surrounded by circles represent the stations. A one-dot chain line represents a boundary line of the resource sharing section. As described above, the route map information K indicating the resource sharing section adds the information of the boundary line of the resource sharing section to the normal route map information and clearly indicates the range of each resource sharing section. Reference numerals E1 to E3 represent shelters, details of which will be described later.

  In addition, the symbols i to i are not information included in the route map information K, but exemplify a train T existing at each point for the following explanation. Information indicating the locations of the trains A to D is detected as train position information P described later. Trains a to i travel in the direction from station 0 to station 9 or in the direction from station 0 to station 7, and the train traveling in the opposite direction is not shown in FIG. The following description is the same for the train T traveling in the opposite direction. Since trains a to i are in the resource sharing section A, they are operated while sharing resources. The same applies to trains located in the resource sharing section B.

  The resource supply amount S corresponds to the amount of power supplied by the substation in the case of power resources, and corresponds to the number of channels that can be used by the radio control device in the case of radio resources.

  The resource information holding unit 11 is a storage device such as a memory or a hard disk drive. The resource information holding unit 11 can be directly written with the resource information RSC including the information as described above by connecting a terminal 5 such as a personal computer. Alternatively, the resource information holding unit 11 may be communicably connected to an external database 6 via a network NW such as a LAN, and the resource information RSC may be read therefrom. In this case, if the resource information RSC is periodically read from the database 6 and the resource information RSC held in the resource information holding unit 11 is automatically updated, the convenience is improved.

  The analysis unit 13 calculates the resource usage U by specifying the train T that is present for each resource sharing section from the train position information P and the route map information K, and based on the usage U and the supply S. The remaining resource information I including the remaining amount Z of resources for each resource sharing section is obtained. The analysis unit 13 includes an arithmetic processing circuit such as a CPU.

  Specifically, the analysis unit 13 searches for the resource sharing section where the train T is present from the train position information P based on the route map information K. For example, as shown in FIG. 2, when trains A to I are operating, trains A to D are in resource sharing section A, trains are in resource sharing section B, and trains are in resource sharing section C. In the resource sharing section D, it is recognized that there is a train line.

  The train position information P is obtained from a CTC (Centralized Traffic Control) station apparatus 3 installed at each station, and includes at least a train position and a corresponding train name. Here, the train name is a name that specifically identifies the train T that is in operation, such as “Toto Loop Line 10”.

  The analysis unit 13 and the train control unit 14 are communicably connected to the CTC station apparatus 3 and acquire the train position information P. The CTC station device 3 is connected to a track circuit provided in each part of the track R via an interlocking device or the like, and detects the presence of the train T therefrom. In addition, since the CTC station apparatus 3 is well-known, detailed description is abbreviate | omitted.

Next, the analysis unit 13 calculates the resource usage U for the entire resource sharing section from the resource consumption of each train T. For example, in FIG. 2, assuming that trains A to I have the same consumption C, the usage amount of the resource sharing section A is U _A = 4 × C, and the usage amount of the resource sharing section B is U _B = 3. × C, the amount of resource sharing section C is the amount of _U C = C, resource sharing interval D is _U D = C.

Here, the consumption amounts U _{A, B, C, and D} were calculated with the consumption C of each train as a fixed value. However, when the resource is the amount of power, the consumption C changes depending on the train organization and speed. Therefore, the usage amount U becomes a rough value. Therefore, in order to obtain a more accurate usage amount U, the resource information RSC including the information on the consumption C according to the train organization and speed is held in the resource information holding unit 11, and the train position information P It is preferable to obtain the composition information and the speed information, search the resource information holding unit 11 for an appropriate consumption C, and calculate it. On the other hand, when the resource is a radio frequency, each train T mostly uses only one channel. Therefore, even if the consumption amount C is calculated with the consumption C as a fixed value 1, the accuracy is not affected. Absent.

  The analysis unit 13 calculates the remaining amount Z by subtracting the usage amount U from the resource supply amount S for each resource sharing section. Furthermore, from this remaining amount Z and consumption C, for example, the number of trains that can be operated in the resource sharing section can also be calculated.

  The remaining resource information I obtained in this way can be used effectively in the operation management of the train T. That is, when the schedule is disturbed, a command can be given to the train T according to the remaining resource information I so that the train T does not travel in the resource sharing section where the remaining amount Z of resources is small.

  First, an embodiment for performing route control or deceleration control of the train T directly from the train operation management device 1 will be described. The train control unit 14 controls the train T according to the remaining amount Z obtained from the analysis unit 13, and is configured by an arithmetic processing circuit such as a CPU.

  As shown in FIG. 1, the train control unit 14 is communicably connected to the CTC station apparatus 3 and transmits a route control signal CT1. The CTC station apparatus 3 is connected to a relay device D provided in the traffic lights S at various places via an interlocking device or the like, and is connected to a switch M provided at various places on the track R. . The CTC station device 3 can change the display of the traffic light S by driving the relay device D according to the route control signal CT1, or can switch the point by controlling the switch M. Some switchboards M switch the route of the train T from the main line to a predetermined shelter E.

  Further, the train control unit 14 is communicably connected to the ATC ground device 4 installed at various locations along the track R, and transmits a deceleration control signal CT2 including information on the set speed. The ATC ground device 4 transmits a deceleration instruction signal via the track R to the train T passing through a predetermined position. In response to this, the ATC on-board device d provided on the train T performs deceleration control to the set speed. Since the ATC ground device 4 and the ATC on-board device d are known, detailed description thereof is omitted.

  The train control unit 14 performs different control according to the train position for each train T. This will be described below.

(1) First control When the train control unit 14 detects a resource sharing section in which the remaining amount Z is less than the predetermined amount X, the train control unit 14 is connected to the resource sharing section where the detected resource sharing section and the track R are connected. Then, the train T traveling toward the detected resource sharing section is advanced to the station, and the route is controlled so as not to advance beyond the station. At this time, the train control unit 14 controls the course of only the train T having a station in the traveling direction in the resource sharing section to which the train position information P belongs.

  The case of FIG. 2 will be specifically described as an example. When the train control unit 14 detects that the remaining amount Z of the resource sharing section B is less than the predetermined amount X, the train control unit 14 stays in the resource sharing section A where the resource sharing section B and the track R are connected, and the resource sharing section B Detecting trains a, b, and d traveling toward Of these, trains A and B have stations 0 and 1 in the direction of travel within resource sharing section B, respectively, so train control unit 14 advances train A to station 0 and train B to station 1, A route control signal CT1 is transmitted to the CTC station apparatus 3 so as not to proceed ahead of 0,1. In response to this, the CTC station apparatus 3 sets the departure signals S of the stations 0 and 1 to the stop display. As a result, trains A and B can be stopped at stations 0 and 1, not between stations, and placed on standby. The stations 0 and 1 may be any stations that can be stopped, and may not be the original stops of trains A and B.

  On the other hand, when it is detected that the remaining amount Z of the resource sharing section B is greater than the predetermined amount X, the train control unit 14 transmits a route control stop signal to the CTC station apparatus 3 and the routes of trains A and B Stop control. As a result, the departure signals S of the stations 0 and 1 can be displayed in progress, and the standby states of the trains A and B can be canceled and can proceed from the stations 0 and 1, respectively.

  In addition, when it is detected that the remaining amount Z of the resource sharing section C is less than the predetermined amount X, the train ho is advanced to the station 3 and the train to the station 5 in the same manner. The course is controlled so as not to proceed. The predetermined amount X may be determined as appropriate according to the design, such as the consumption of resources for several trains T, and the same applies to the following description.

(2) Second control When the train control unit 14 detects a resource sharing section in which the remaining amount Z is less than the predetermined amount X, the train control unit 14 is connected to the resource sharing section where the detected resource sharing section and the track R are connected. Then, the route of the train T traveling toward the detected resource sharing section is controlled toward a predetermined shelter E where the passenger can get off. At this time, the train control unit 14 indicates a track R between two stations that are adjacent to each other across the boundary of the resource sharing section (between stations indicated by bold circles in FIG. 2. The route is controlled only for the train T that is on the line.

  The case of FIG. 2 will be specifically described as an example. When the train control unit 14 detects that the remaining amount Z of the resource sharing section B is less than the predetermined amount X, the train control unit 14 stays in the resource sharing section A where the resource sharing section B and the track R are connected, and the resource sharing section B Detecting trains ai traveling toward Among these, the train control unit 14 transmits a route control signal CT1 to the CTC station apparatus 3 so that the train D existing in the boundary section of the resource sharing sections A and B is advanced to the resting place E1. In response to this, the CTC station apparatus 3 controls the appropriate switch M to perform point switching. Thereby, the train D can be guided to the resting place E1 and stopped.

  Moreover, when the train control unit 14 detects that the remaining amount Z of the resource sharing section D is less than the predetermined amount X, the train control unit 14 turns the train C existing in the boundary section of the resource sharing sections A and D to the resting place E2. The course is controlled so as to advance. Similarly, when it is detected that the remaining amount Z of the resource sharing section C is less than the predetermined amount X, the route is set so that the train existing in the boundary section of the resource sharing sections B and C proceeds to the resting place E3. Control.

  Thus, even if the train T has no station that can be stopped in the resource sharing section where the line is located, that is, the train T that exists in the boundary section, the situation where the station stops between the stations can be avoided by stopping at the resting place E. The shelter E may be a place where passengers can safely get off, such as a vehicle base.

  This route control is performed when there is no prospect of resource restoration and the operation of the train T becomes extremely difficult. For example, in the case of FIG. 2, the train control unit 14 lacks resources in the resource sharing section B and the resource sharing section C and further in the resource sharing section that is connected to the train share section (that is, remaining amount Z <predetermined amount X). Is detected, or when the resource shortage state in the resource sharing section B continues for a predetermined time or more, it is determined that there is no possibility of resource recovery. In this case, the train D cannot be operated in addition to the restoration of the diamond. Therefore, by controlling the route of the train D and guiding it to the resting place E1, it is possible to safely get off the passengers and to remove the train D from the main line. Can be promoted. For this reason, it is desirable to select a place that can accommodate more trains T as the shelter E.

(3) Third control When the train control unit 14 detects a resource sharing section in which the remaining amount Z is less than the predetermined amount X, the train control unit 14 is connected to the resource sharing section where the detected resource sharing section and the track R are connected. The train T traveling toward the detected resource sharing section is subjected to deceleration control. At this time, the train control unit 14 performs deceleration control only on the train T existing on the track R (that is, the boundary section) between two adjacent stations across the boundary of the resource sharing section.

  The case of FIG. 2 will be specifically described as an example. When the train control unit 14 detects that the remaining amount Z of the resource sharing section B is less than the predetermined amount X, the train control unit 14 stays in the resource sharing section A where the resource sharing section B and the track R are connected, and the resource sharing section B Detecting trains ai traveling toward Among these, the train control unit 14 transmits a deceleration control signal CT2 to the ATC ground device 4 at an appropriate position so as to perform deceleration control of the train D existing in the boundary section. Receiving this, the ATC ground device 4 transmits a deceleration instruction signal to the train D, and the train D is decelerated by the ATC onboard device d.

  In this deceleration control, the train control unit 14 predicts the time required for the resource shortage state of the resource sharing section B to be resolved from the train position information P of the train host existing in the resource sharing section B. Then, an optimum speed is calculated so that the train D can enter the resource sharing section B after the required time has elapsed, and this is used as a set speed to generate the deceleration control signal CT2. As a result, the train D can enter the resource sharing section B after the remaining amount Z of the resource sharing section B has sufficiently increased without stopping between the stations.

  On the other hand, when it is detected that the remaining amount Z of the resource sharing section B is greater than the predetermined amount X, the train control unit 14 transmits a deceleration control stop signal to the ATC ground device 4 to perform the deceleration control of the train D. Stop. Thereby, the train D can cancel | release the deceleration state and can drive | work at normal speed.

  In this way, even if the train T has no station that can be stopped in the resource sharing section where the line is located, that is, the train T that is located in the boundary section, it is possible to share the adjacent resource in a timely manner without slowing down between the stations. You can enter the section. Therefore, this deceleration control is performed when there is a possibility of resource recovery in the entering resource sharing section, contrary to the case of the second control described above.

  Although the 1st-3rd control described so far shall be properly used for every train T according to the train position, it is not limited to this and according to design as long as the same effect is produced. What is necessary is just to use suitably. For example, deceleration control may be performed without the train T existing in the boundary section, and if there is a resting place E that can be entered, route control may be performed toward that.

  Moreover, even if at least one of the first to third controls is employed, the above-described effects can be obtained, but it is desirable to employ all of them. FIG. 3 shows an operation flow of the train control unit 14 in this case. This operation flow is repeatedly executed for each resource sharing section.

  First, the train control unit 14 determines whether or not the remaining amount Z obtained from the analysis unit 13 is less than a predetermined amount X (reference numeral St1). If the remaining amount Z <predetermined amount X, the train T connecting the corresponding resource sharing section and the track R is detected (reference St2). Furthermore, the presence or absence of the train T existing in the boundary section among the detected trains T is determined (reference numeral St3).

  When there is no train T existing in the boundary section, the presence / absence of the train T existing in the boundary section is determined (reference St6). And if there is the train T which exists in lines other than a boundary area, the 1st control mentioned above will be performed to the applicable train T (code | symbol St7). Thereby, the train T can be stopped at an appropriate station and can be made to stand by.

  On the other hand, if there is a train T existing in the boundary section, it is further determined whether or not there is a possibility of resource recovery in the corresponding resource sharing section (reference St4). Specifically, as described above, when a predetermined number of resource sharing sections with insufficient resources are continuously detected along the trajectory R, or when a resource shortage state continues for a predetermined time or more, recovery is likely. Judge that there is no.

  If there is a possibility of resource recovery, the above-described third control is executed (reference St5). Thereby, the train T can be decelerated. On the other hand, if there is no possibility of resource recovery, the second control described above is executed (reference St9). Thereby, the train T can be guided and stopped at the resting place E. And if it is the train T which exists in lines other than a boundary area, the 1st control mentioned above will be performed to the applicable train T (code | symbol St6, St7).

  As described above, the train control unit 14 suitably stops, changes the route, or decelerates the train T according to the train position. However, when the resource is not in a shortage state, the PRC device 2 installed at the command center is connected to the train T. The operation is managed. Similar to the train control unit 14, the PRC device 2 is connected to the CTC station device 3 of each station so as to be communicable, and performs route control of the train T. Since the PRC device 2 is publicly known, detailed description is omitted.

  In each CTC station apparatus 3, since a control signal is input from both the PRC apparatus 2 and the train control unit 14, a conflict of control operations may occur. However, since the train control unit 14 performs route control from the viewpoint of fail-safe when a resource shortage occurs, each CTC station apparatus 3 gives priority to the control signal CT1 of the train control unit 14 and performs a control operation. To do. On the other hand, when it is desired to avoid competition of control operations, the control by the train control unit 14 may not be performed, and the remaining resource information I may be notified to the PRC device 2 so that only the PRC device 2 controls the course of the train T.

  In the embodiment in this case, the train operation management device 1 includes a notification unit 12. The notification unit 12 is communicably connected to the PRC device 2 and notifies the PRC device 2 of the remaining resource information I. The notification unit 12 includes a communication control LSI and the like, and transmits the remaining resource information I after converting it into a data format according to the PRC device 2. According to this embodiment, the PRC device 2 which is an existing facility can be used, and the train control unit 14 can be omitted from the train operation management device 1, so that the cost can be reduced.

  Of course, the remaining resource information I may be simply displayed on a monitor or the like, and the person in charge of train operation may see this and give a command to the train T. In the embodiment in this case, the train operation management device 1 includes a display unit 15. The display unit 15 displays the remaining resource information I for each resource sharing section. This remaining resource information I includes the number of trains that can be operated by the remaining amount Z in the resource sharing section.

  FIG. 4 is a screen display example of the display unit 15 when the resource is power. Here, “surplus power” is a numerical value of the remaining amount Z, and “decrease level” represents a stepwise level according to the numerical value of the remaining amount Z. For example, “A” is displayed when X> Z, “B” is displayed when 2 × X> Z ≧ X, and “C” is displayed when Z ≧ 2 × X.

  The “number of trains that can be entered” represents the number of trains that can enter the resource sharing section for each route. This can be calculated by dividing the remaining amount Z by the consumption C of the train T. Here, as for the consumption C, a numerical value for each route may be stored in the resource information holding unit 11 in advance.

  Further, the “name of approaching train” can be obtained from the train name output together with the train position information P as described above. According to this embodiment, since the train control is not performed, not only the effect of low cost but also the effect of extremely easy realization can be obtained.

  Next, a case where there is an overlapping section (hereinafter referred to as a resource overlapping section) in a part of adjacent resource sharing sections will be described. FIG. 5 is a route diagram showing a resource sharing section when there is a resource overlap section. Here, there are resource overlapping sections in adjacent resource sharing sections A and B, and the range is a portion sandwiched between line segment L1 and line segment L2 which are one end of resource sharing sections A and B.

  In this example, when the resource sharing section B is in a resource shortage state (remaining amount Z <predetermined amount X), control of the trains C and D existing in the resource overlap section becomes a problem. Therefore, considering the case where the trains C and D have traveled ahead of the line segment L2, the trains C and D cannot use the resources allocated to the resource sharing section A and may not be able to operate. . Therefore, in this example, the line segment L2 is regarded as the boundary line of the resource sharing sections A and B for control.

  That is, the train C is advanced to the station 4 by the first control described above, and waits until the resource shortage state in the resource sharing section B is resolved. When there is no expectation of the resource shortage state, the train D is guided to the resting place E2 by the second control described above and stopped. On the other hand, if not, the train D is decelerated and controlled by the above-described third control, and after the resource shortage state in the resource sharing section B is resolved, the vehicle is advanced forward from the line segment L2. As a result, the same effect as described above can be obtained. That is, when it is detected that the resource sharing section where the resource overlapping section exists is in a resource shortage state, the resource overlapping section is not the detected resource overlapping section but the adjacent resource sharing section where the trajectory is connected to the resource sharing section. What is necessary is just to control the train T.

  In the embodiment described so far, the railway system according to the present invention is illustrated as being applied to the train operation management apparatus 1 installed at the command station. However, the present invention is not limited to this, and the ATC ground apparatus 4 or the like. It can also be applied to other train control devices. However, in this case, needless to say, it is necessary to appropriately provide communication means with other devices such as the ATC ground device and the CTC device as described above.

  As described above, according to the railway system according to the present invention, even when the schedule is disturbed, it is possible to prevent a situation in which the train is stopped between stations due to lack of resources. Therefore, according to the present invention, it is possible to provide a railway system that can effectively contribute to safe train operation.

  Although the contents of the present invention have been specifically described above with reference to the preferred embodiments, it is obvious that those skilled in the art can take various modifications based on the basic technical idea and teachings of the present invention. It is.
