Description

  The present invention relates to a travel distance record grasping technology for a railway vehicle, and more particularly to a system capable of grasping a travel distance record of a train traveling in a section without a vehicle tracking function.

  In order to appropriately manage railway vehicles, it is necessary to grasp the travel distance of each vehicle (formation). For example, a number of 3 to 5 digits is assigned to each vehicle (organization) constituting the train, and by using this number to track each vehicle (organization), Vehicle management such as vehicle maintenance is performed. Also, by tracking the vehicle (training), it is possible to know how much the vehicle (knitting) has traveled, and the necessity of periodic inspections according to the number of mileage and the number of mileage of each vehicle (knitting). Judgment is made on the presence or absence and whether or not to treat as a scrap car.

Note that “knitting” means a combination of a plurality of vehicles, and since the operation is usually performed in knitting units, the mileage of the plurality of vehicles constituting one knitting is basically the same.
Conventionally, in a railway system, the number of mileage of each vehicle (formation) is grasped based on train operation information (diagram information). It is also possible to grasp the number of mileage based on train position information from an operation management system that can grasp the position of the train. As an invention related to a vehicle management device that calculates the number of travel distances based on train position information (train operation information) from an operation management system, there is one disclosed in Patent Document 1, for example.

Japanese Patent Laid-Open No. 7-81571

  Conventionally, the train position is grasped by a method using information from a track circuit by an operation management system and a method using information from a digital wireless communication system (digital train wireless system). Currently, there are routes in the Tokyo metropolitan area that employ either one of the methods and routes that employ both methods. However, there are some untrackable sections (in the case of all sections and in some sections) that do not employ any of the conventional lines, and if the vehicle (formation) travels in such a section, There is a problem that it is difficult to accurately grasp the travel route and the number of travel distances.

  In addition, in the said patent document 1, it is not described concretely how an operation management system acquires train position information, and when there is an untraceable section mentioned above, the exact number of mileage is grasped. The problem of becoming difficult and the technology for solving the problem are not described.

The present invention has been made paying attention to the above-described problems, and even when the vehicle (knitting) may travel in an untrackable section, a railway vehicle capable of grasping the accurate number of travel distances. The object is to provide a mileage performance grasping system.

The process execution control unit
If it is determined that a vehicle that has left the nearest station in the untraceable section has entered the untrackable section, it is determined whether the vehicle is a forwarding vehicle. Double the distance up to 1 point as the travel distance of the vehicle, and when it is determined that the vehicle is a forward vehicle, double the distance from the station to the second point is the travel distance of the vehicle Added as.
According to the above configuration, even when a vehicle (knitting) may travel in an untrackable section without providing new equipment such as a radio base station in the untrackable section, The number of mileage can be accurately grasped. In addition, it is possible to grasp an accurate travel distance record including a distance traveled as a forward train.

Here, preferably, the process execution control unit is
When a vehicle that departs from a station that is closest to the untraceable section enters the untraceable section, the time that cannot be tracked is counted, and the untrackable duration time is round-trip from the station to the first point. When it is shorter than the required time and longer than the required round-trip time from the station to the second point, it is twice the distance from the station to the second point regardless of whether the vehicle is a forwarding vehicle. The distance is added as the travel distance of the vehicle.
According to such a configuration, the time that the train was in the untraceable section is counted using the timer function of the process execution control unit without providing new equipment or facilities, and the untraceable section is based on the time. You can grasp the distance traveled.

Furthermore, preferably, when the untraceable section is an underground section, the radio base station is located on the ground portion corresponding to only one main station, for example, a starting station among a plurality of stations in the underground section. Provided,

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, an embodiment of a railway vehicle mileage track record grasping system according to the present invention and a vehicle management device constituting the system will be described with reference to the drawings.
FIG. 1 is a functional block diagram showing the configuration of the travel distance record grasping system according to the first embodiment.
The mileage track record grasping system of this embodiment is a radio communication system (digital train radio system) of a digital radio communication system having a vehicle management device 100 and a vehicle tracking function connected to the vehicle management device 100 via a network 200. The vehicle tracking system 300 which consists of these. Hereinafter, it is described as a train radio system 300.

  The vehicle management apparatus 100 includes a process execution control unit 110 configured by an arithmetic processing device such as a CPU (Central Processing Unit), and data configured by a storage device such as a ROM (Read Only Memory) and a RAM (Random Access Memory). Storage unit 120, input processing unit 131 that processes input from an input operation device such as keyboard 141 and mouse 142, display processing unit 132 that displays an image on display device 143 such as a liquid crystal panel, and transmission and reception of data between them And a data receiver 134 that receives data from the central device 330 of the train radio system 300 via the network 200.

  In the present embodiment, the process execution control unit 110 calculates the travel distance of each train based on the position information (starting station information, passing station information, end station information, etc.) of each train acquired from the train radio system 300. A travel distance calculation unit 111 having an untrackable section travel determination unit 112 that determines whether or not each train has traveled in an untrackable section that cannot be tracked by the train radio system 300; A function unit such as a travel distance result calculation unit 113 that calculates the travel distance result by adding the travel distance of the untraceable section is provided.

  The data storage unit 120 also includes a program storage unit 121 for storing a travel distance calculation program executed by the process execution control unit 110, an untrackable section travel determination program, a travel distance result calculation program, and the like. A fixed data storage unit 122 that stores fixed data such as a distance between stations, a travel distance record data storage unit 123 that stores travel distance record data calculated by the travel distance record calculation unit 113, and the like are provided. The fixed data storage unit 122 may receive and store operation plan data (diamond information) from a vehicle management planning system (not shown) or the like.

  FIG. 2 shows a configuration example of a train radio system 300 as a train tracking system. The train radio system 300 includes a radio base station 310 installed at a predetermined distance (2 to 3 km) along a railway line, an in-vehicle device 320 mounted on each train T, and a command room (transport command). A central device 330 is provided. The in-vehicle device 320 includes a digital wireless communication device 321 as a mobile station, a GPS (Global Radio Positioning System) receiver 322, and a storage device (memory) that stores a composition number assigned to each composition as identification information. 323, and the position information received by the GPS receiver 322 and the composition number as identification information are transmitted to the central apparatus 330 via the radio base station 310 by the digital radio communication apparatus 321.

In addition, about the technique which transmits the positional information on a train to the central apparatus of a command room based on the received GPS information provided with a GPS receiver, it describes in Unexamined-Japanese-Patent No. 2010-177982, for example, The system of this embodiment Since the train position information can be transmitted using the same known technique, detailed description is omitted. The wireless base station 310 and the central device 330 are connected by a wired line. A monitor is provided in the command room, and the position of the train is displayed on the monitor.
In addition, there are routes in which a plurality of vehicles are connected to form one train (for example, a five-car train or a ten-car train) and run together. Since the GPS receiver and the wireless communication device are mounted on the vehicle, the travel distance can be calculated for each train.

  By the way, at present, in many line sections, an operation management system using a track circuit is provided, and the train position can be grasped in the system. Therefore, an operation management system is used as the vehicle tracking system 300 constituting the mileage performance grasping system of FIG. 1, and the vehicle management device 100 acquires train position information from the operation management system to determine the mileage of each train (formation). It is also possible to calculate.

  FIG. 3 shows a configuration example of the operation management system 300 '. As shown in FIG. 3, the operation management system 300 ′ is connected to a central management apparatus (central area common central apparatus) 340 and communicably connected to the central management apparatus 340 via a central network N1 provided for each area. A plurality of line distinction management devices 350 and a plurality of station control devices 360 installed at each interlocking station in the line section and connected to the line distinction management device 350 via the operation management network N2 so as to be communicable. Has been. Then, an interlocking device 370 is provided under the control of the station control device 360, and the interlocking device 370 controls a signal device and a turning device (not shown) based on the signal current of the track circuit 380. The central management device 340 can grasp the position of the train (knitting) traveling on each route by sucking the state information of the track circuit 380 through the station control device 360 and the line distinction management device 350.

  Note that the routes managed by the operation management system are not all routes and are not introduced to some routes. Therefore, when the train travels in the section where the operation management system has not been introduced, the train position cannot be grasped, so each train cannot be tracked by the operation management system 300 ′ as in the vehicle management device 100 of the present embodiment. The untrackable section travel determination unit 112 that determines whether or not the untrackable section has been traveled, and when the formation determines that the untrackable section has traveled, the travel distance is calculated by adding the travel distance of the untrackable section It is effective to provide functional units such as the distance performance calculation unit 113.

Next, the method of calculating the travel distance record when the train (formation) travels in the untraceable section will be specifically described by dividing it into a plurality of cases.
The first case is a case where the track branches in a non-trackable section where no wireless base station is provided, and the vehicle tracking system cannot grasp which of the two routes is running. . Specifically, as shown in FIG. 4 (A), on a route that is usually turned back at E station at the boundary of a section that can be tracked, the F station or G that is in the untrackable section ahead. This is a case where the vehicle travels to the station and turns back at F station or G station, where there is a gap in the minimum times Tf and Tg required for the round trip (provided that Tg <Tf). In addition, the required time between each station is predetermined in the transportation plan system which produces an operation plan, and the required time can be used for determination.

In this case, if the time T0 until it can be tracked again after being unable to track at E station is Tg ≦ T0 <Tf, it is determined that the train (train) has traveled to G station and turned back at G station. Add twice the distance between EG stations to the distance traveled.
On the other hand, if T0> Tf, it may turn back after stopping at G station for a long time. From this condition, it cannot be determined whether it is turned back at F station or G station. Add and judge. For example, traveling to G station (including the indwelling line) may be limited to the forwarding operation for turning back, and in that case, it is a condition whether or not the forwarding operation is performed.

And it can be performed based on the following judgment criteria whether it is forwarding operation.
For example, in the operation plan, traveling in a certain section (between E and G in this case) may be limited to the forward operation. In that case, whether or not the forward operation is performed with reference to the operation plan information. If it determines, and it is a forwarding driving | running | working, it will judge that it will be the return driving | running | working operation in G station, and will add 2 times the distance between EG stations to a travel distance. Further, if it is not forward driving, it is determined that it is a turning-back operation at F station, and twice the distance between EF stations is added to the traveling distance.
In the above method, as shown in FIG. 4 (B), the track is untrackable at the end of E station, and the track branches to F station and the vehicle base (including the detention line). It can also be applied to the case of turning back at the base.

  In addition, whether or not it is forward driving is based on information (vehicle weight) provided from a vehicle monitor that measures the weight of the vehicle body (including passengers) provided between the vehicle body and the bogie of the E station. For example, if the calculated boarding rate is less than 1%, it may be determined that the vehicle is empty, i.e., forwarding, and if it is 1% or more, it may be determined that it is not forwarding. Since the vehicle monitor for measuring the weight of the vehicle body is often provided for adjusting the pressure of the air spring, it can be used. For example, if the weight of the vehicle body is equal to or less than the weight corresponding to the boarding ratio of 1%, it may be determined as forwarding.

In addition, since it is determined that the conductor does not get on the forward train, in that case, the operation panel such as the air conditioning handled by the conductor or the departure signal button is operated when leaving the E station. You may make it judge that it is a forwarding train on condition that there is no.
Even when the vehicle tracking system is a digital train radio system, the above conditions can be determined if radio communication is possible at station E.

The second example is a case where the vehicle tracking system is a digital train radio system and there is an underground section (including a subway) in a part of the route.
In such a case, a radio base station is installed on the ground portion of a main station among a plurality of underground stations, and information on trains that arrive at and depart from the radio base station can be transmitted. And it considers that the area was drive | worked from the travel required time between predetermined stations, and adds the distance between stations known beforehand as a travel distance performance.

In addition, when there are underground sections, radio base stations are not installed at a plurality of main stations, but only at the starting station, and the time and schedule information when the station arrives and departs The travel distance may be calculated using If there is no large diamond disturbance, the travel distance can be calculated by such a method.
In addition, when the vehicle tracking system is based on either a digital train radio system or an operation management system, an LCX (Leaky Coaxial Cable) is laid in a non-trackable section, and the train that travels in this section You may comprise so that data may be transmitted / received by LCX radio | wireless communication, a train position may be tracked, and a travel distance may be calculated.

Next, an example of the procedure of the method for calculating the travel distance record in the untraceable section shown in FIG. 4A by the process execution control unit 110 of the vehicle management apparatus 100 configuring the travel distance record grasping system of the present embodiment. This will be described with reference to the flowchart of FIG. In addition, the process according to this flowchart is started when a train arrives at E station.
When this process is started, the process execution control unit 110 of the vehicle management apparatus 100 first determines whether or not the train of interest has departed E station (step S1). Here, if it is determined that the train has departed from E station (Yes), the process proceeds to step S2, and in the case of the first case, the wireless communication is possible. In the case of the second case, the train is determined based on information from the track circuit. It is determined whether or not there is a track in a trackable section.

When it is determined that the track is in the trackable section (Yes), the process proceeds to step S11 to determine whether the train has arrived at the D station. And if it determines with the train having arrived at D station (Yes), it will progress to step S12 and will add the distance between ED stations to a driving | running | working distance performance.
On the other hand, if it is determined in step S2 that the track is not in the trackable section (No), that is, if it is in the untrackable section, the process proceeds to step S3, and a timer operation is performed. Then, it progresses to step S4, it determines again whether it exists in the trackable area, and if it determines with not being in the trackable area (No), it will return to step S3.

  If it is determined in step S4 that the track is in a trackable section (Yes), the process proceeds to step S5, and a time T0 in which tracking is impossible is calculated with reference to the timer. Subsequently, it is determined whether the untraceable time T0 is larger than the round trip time Tg between the EG stations and smaller than the round trip time Tf between the EF stations (step S6). Here, if it determines with "Yes", it will progress to step S10 and will add the distance of 2 times the distance between EG stations to a travel distance performance.

On the other hand, when it is determined “No” in step S6, the process proceeds to step S7, and it is determined whether or not the untraceable time T0 is longer than the required round-trip time Tf between the EF stations. Then, if it is determined that the untraceable time T0 is longer than the required round-trip time Tf between the EF stations (step S7: Yes), the process proceeds to step S8, and it is determined whether or not the train is a “forward train”. If “Yes” is determined, the process proceeds to step S10, and a distance twice the distance between the EG stations is added to the actual travel distance.
If it is determined in step S8 that it is not a “forward train” (No), the process proceeds to step S9, and a distance twice as large as the distance between the E-F stations is added to the actual travel distance.

  On the other hand, if it is determined in step S7 that the untraceable time T0 is not larger than the required round-trip time Tf between the EF stations, in this case, the untraceable time T0 is longer than the required round-trip time Tg between the EG stations. Since it is small, it returns to step S2 and repeats the said process. And if tracking is possible at this time, it will transfer to step S11 and it will be determined whether the said train arrived at D station. Then, if it determines with the train having arrived at D station (Yes), it will progress to step S12 and will add the distance between ED stations to a driving | running | working distance performance. Thereby, when turning back at E station, even if tracking becomes temporarily impossible for some reason, calculation of a correct mileage can be performed.

  Although the invention made by the present inventor has been specifically described based on the embodiment, the present invention is not limited to the embodiment. For example, in the above-described embodiment, the case where either the operation management system or the train radio system is provided as a vehicle tracking system has been described. However, the present invention introduces both the operation management system and the train radio system. It can also be applied to existing routes and sections.

  Even for routes and sections where both the operation management system and the digital train radio system are installed, the range covered by the operation management system and the range covered by the digital train radio system are different, so one system (for example, digital When the train travels in a section (for example, an underground section) that cannot be covered by the system, the train position information is acquired from the other system (operation management system). . And about the section which cannot be covered by any system, it is good to calculate the travel distance performance of the untraceable section by the untrackable section travel determination unit 112 and the travel distance result calculation unit 113 of the vehicle management apparatus 100 described in the above embodiment.
