TECHNICAL FIELD OF THE INVENTION
The present invention relates to a distributed operation management system that manages the operation of trains in control area units, and more particularly to a system suitable for performing operation management of train locations in each control area.
[0002]
[Prior art]
Conventionally, the automatic route control device installed at each station tracks the location of the train in its own control area, but at the timing of detecting the train entering the control area, Is assigned to the approaching train, and the route control of the approaching train is performed based on the schedule information of the train ID. Here, the course control refers to selection of a track, control of a traffic light or a signal light, etc., while tracking the train location. The automatic route control devices at each station operate asynchronously. The trajectory in the control area is sectioned in units of several hundred meters, and the section where the train is located is automatically detected by an automatic route control device that manages the area via detection means or the like. This is tracking of the train location. Adjacent A, In the station B, the automatic course of the case, route control apparatus A station B station at a specific timing t ₁ in starting the self-control area of the traveling train P from station A to station B The train ID of the departure train is transmitted to the control device.
[0003]
With automatic route control apparatus Station B latches the train ID, at timing t ₂ of detecting the entry of the train P self control area, and the train ID which is the head of the train ID and the latch diamond information at that time Are compared, and if they match, the first train ID of the schedule information is assigned to the entered train, and if they do not match, the train ID received and latched is forcibly assigned. By taking these procedures into account, the takeover of the train traveling between the automatic route control device at station A and the automatic route control device at station B is realized. Generally, a train that has advanced from station A enters station B without being overtaken by another train. In addition, since the control area of the automatic route control device at the station A and the control area of the automatic route control device at the station B are continuous, the train management must be performed by the automatic route control device at the station A from the automatic route control device at the station A. Move to device. Therefore, the automatic route control device at the station B need only latch the train ID received from the station A for one train. This corresponds to the automatic route control devices of all the stations, and all have the mechanism of latching the train ID of one train.
[0004]
[Problems to be solved by the invention]
However, when trying to use the above-mentioned conventional technology in a line section with a narrow train interval and a high train operation density, the following problem occurs.
Consider an example in which trains P and Q enter from station A to station B at narrow intervals in the order of P → Q. The above prior art, and the timing _{t 2} of the train P, a is the departure time _{t 10} trains Q (corresponding to the _{t 1),} it is assumed that the order of _{t 2} → _{t 10.} Therefore, when the automatic route control device of the station A cannot detect that the train P is on the last track section of the control area of the train of the station A even though the train is on the track (failure of on-rail detection). before B station automatic route control device detects the timing t ₂ of that has entered the train P in its control area, automatic route control apparatus a station will leave the final track segments of the self-control area It is determined that the train is departed, and the signal light for departure of the train Q stopped at the station A is set to blue and departure is OK (in this way, if the previous train leaves the final track section of its own control area, this The departure condition is to set a green signal indicating the departure of the train after stopping on the platform or the like in the control area). At time t ₁₀ which in this green light _{(corresponding} to the t _1), route control apparatus A station, thus sends train Q train ID and (Q) the automatic route control apparatus B station. The automatic route control device at the station B receives the train ID (Q) of the train Q, deletes the registered train ID (P), and latches the train ID (Q) instead. This is because the system is designed to latch IDs for one train. As a result, the route control device of the station B erroneously assigns the train ID (Q) even though the head ID of the schedule information at the station B at this point is ID (A).
[0005]
Also, if the first track section of the control area in the automatic route control apparatus B station has failed (on-rail detection failure) before the automatic route control apparatus B station detects the timing t _2, automatic station A route controller detects the timing t _10, the case of transmitting train Q train ID and (Q) the automatic route control apparatus B station, automatic route control apparatus B station receives the train Q train ID (Q) However, since the train ID (Q) is latched in place of the already held train ID (P), the automatic route control device at station B incorrectly assigns the train ID (Q) to the train ID (Q), causing the same problem as described above. I do.
Furthermore, even though the first track section of the control area of the automatic route control device at the station B detects the presence of the train P, the automatic route control device at the station B is detected due to a communication delay or the like. also, before the automatic route control apparatus B station detects the timing t _2, the automatic route control apparatus a station detects the timing t _10, the automatic route control device for a train Q train ID (Q) B Station , The automatic route control device at the station B receives the train ID (Q) of the train Q and latches the train ID (Q) instead of the train ID (P) already held. Therefore, the wrong assignment is made to the ID (Q) of the train Q, and the same problem as described above occurs.
[0006]
An object of the present invention is to provide a distributed train operation management system that can avoid erroneous assignment of a train ID when used in a line section having a high train operation density, and that enables assignment of a correct train ID. It is in.
[0007]

BEST MODE FOR CARRYING OUT THE INVENTION
An embodiment of the present invention will be described with reference to the drawings.
FIG. 1 shows a configuration example of a distributed operation management system according to the present invention. The automatic route control devices 1 and 2 are provided at adjacent stations A and B, and perform route control of the stations A and B asynchronously with each other. The automatic route control devices 1 and 2 are connected to a network 5 via communication lines 3 and 4, respectively. The automatic route control devices 1 and 2 have the same configuration, and have a communication interface 6 for communicating with the automatic route control devices of other stations via the network 5; An interface 7 for taking in information of the equipment at the position, a train tracking processing unit 8 for creating a train location information DB based on the information taken in from the interface 7, and holding a diagram of each train. A route control processing unit that performs station point switching and traffic light control so that trains can be operated according to the schedule information based on the schedule information DB 9 and the train location information DB and the schedule information DB 9 created by the train tracking processing unit 8. It consists of ten.
[0013]
The train tracking processor 8 generates information on where each train in its own control area is located on each track, detects the timing of transmitting the train ID, and transmits the train ID. A train ID transmitting unit 12, a train ID receiving unit 13 for receiving a train ID, a train ID storage memory 14 for storing the received train ID, and detecting that a train has entered its own control area and assigning a train ID. And a train ID assignment processing unit 15.
The diagram information DB holds the order in which trains enter as scheduled, and the train ID assignment processing unit 15 can extract the order in which trains enter.
[0014]
Next, a detailed operation of each process shown in FIG. 1 will be described with reference to FIG. The train ID transmission unit 12 of the automatic route control device 1 at the station A detects the train ID transmission timing of the train P located in its own control area, and sends the train ID (P) to the automatic route control device 2 at the station B. Send.
The train ID receiving unit 13 of the automatic route control device 2 at the station B receives the train ID (P) from the automatic route control device 1 at the station A via the communication interfaces 3 and 4, and the train ID received by the train ID memory 14. (P) is stored. The memory 14 has a capacity capable of storing a plurality of train IDs, and is, for example, a FIFO type memory, and takes out the earliest (oldest latched) train ID first. FIG. 3 shows an example of storage in the memory 14. The addresses are divided in a record format, and a plurality of train IDs are stored. The memory 14 is searched from the top record, and the received train ID (P) is stored at the top of an empty record.
The train tracking processing unit 11 of the automatic route control device 2 at the station B detects the entry of the train P and updates the information in the train location information DB.
[0015]
The train ID allocation processing unit 15 detects that the train P has entered the control area of the automatic route control device 2 at the station B with reference to the train location information DB, and based on the diagram information DB 9, the first train in the order of entry at the station B. The train ID (P) is extracted from the first record of the train ID storage memory 14 and the train ID (P) extracted from the schedule information DB 9 is compared with the train ID extracted from the train ID storage memory 14. If they match, the extracted train ID is assigned to the train P, and if they do not match, the train ID extracted from the train ID storage memory is assigned to the train (P).
At each of stations A and B, even if the on-rail detection in one track section in the own control area fails, it can be detected in the next track section. It can be detected, and there is no problem in route control. Therefore, even in the case of t ₁₀ → t ₂ between t ₁₀ and t ₂ (see the above-mentioned problem), there is no problem in route control as long as IDs are correctly assigned.
[0016]
Next, the timing of writing and erasing to the train ID storage memory 14 will be described with reference to FIG. The train ID storage memory 14 shown in FIG. 3 has an n-record configuration, and can store train IDs in the order of reception. The train ID receiving unit 13 of the automatic route control device 2 at station B searches the train ID storage memory 14 from the first record at the timing received from the automatic route control device 1 at station A, and stores the received train ID in an empty record. Write. In the figure, an example is shown in which the first to third records are empty, and this train ID (P) is latched at the third record position, which is the first empty record. Also, at the timing when the automatic route control device 2 of the station B detects the entry of the train into the control area, the train ID assignment processing unit 15 of the station B extracts the train ID from the first record of the train ID storage memory 14 and performs the train ID assignment process. Do. Thereafter, the extracted train ID is deleted from the train ID storage memory 14, and if the train ID is registered in the second and subsequent records, the train ID is rewritten to the left. That is, the rank of the next highest train ID increases as the highest train ID. Subsequent ranks also move up sequentially. While the train ID assignment processing unit 15 is operating the train ID storage memory 14, the train ID receiving unit 13 cannot write the train ID, and conversely, the train ID receiving unit 13 stores the train ID in the train ID storage memory 14. While the ID is being written, the train ID assignment processing unit 15 cannot operate the train ID storage memory 14.
[0017]
FIG. 4 shows an example of the present invention for a line section having a high train operation density in which _nine trains P _{1 to} P ₉ are located at stations A to F. The automatic route control devices distributed from station A to station F operate asynchronously. The present invention is effective when the train ID transmission timing of the automatic route control device at the preceding station and the train ID reception timing of the automatic route control device at the rear station are different from each other at adjacent stations.
[0018]
In addition, in order to prevent the reception failure at the B station, it is possible to transmit the train ID from the A station at two timings. At station B, if the same train ID is received, it is discarded. This makes it possible to achieve toughness in transmission and reception.
[0019]
【The invention's effect】
As described above, according to the embodiment, erroneous assignment of a train ID between the automatic route control device at station A and the automatic route control device at station B, which are operating asynchronously, is prevented. Therefore, the train schedule is disturbed not only in the line sections having a relatively low train operation density but also in the line sections having a high train operation density as shown in FIG. In such a case, when the automatic route control device of the present invention is used, continuity of train tracking can be secured without overwriting the train ID.
In addition, the interface between the automatic route control device at the station A and the automatic route control device at the station B is not changed from the conventional method, thereby maintaining the independence between the automatic route control devices at the respective stations, and the distributed operation management system. As a result, maintainability and expandability can be further improved.
[0020]
【The invention's effect】
According to the present invention, incorrect assignment of a train ID can be prevented.
