Abstract

PROBLEM TO BE SOLVED: To perform without assistance operation control from a central device including a section where a station device is set by connecting to each other through a low speed transmission line the central device for generally controlling small-scale stations and the station device arranged at each large-scale station so as to control a section between large-scale stations. SOLUTION: An effective diagram of a station device is computed by a diagram processing 4 and transmitted to the diagram DB of the station device through a transmitting processing 6 and a receiving processing 9. At that time, train information on effective diagram is transmitted to all station devices and station information is transmitted only to the applicable station device so that information to be transmitted can be reduced. Since operation information such as revised diagram at the time of rearrangement of operation, a train number present on a railroad line in the section between the station devices and between the central devices, and a signal in the section between the station devices from the central device is few, it is directly transmitted from the central device to the station device and vice versa.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an operation management system for a railway, and more particularly, to an operation management device of a centralized control type and an operation management device installed independently in a large-scale station via a transmission line. And an operation management system that realizes comprehensive train control of the entire line section.

[0002]

2. Description of the Related Art Conventionally, a centralized operation management device (hereinafter referred to as a "central device") aims at automatically controlling traffic lights and switches on a whole line section of an area based on a diagram. However, for stations with a large number of traffic lights and stations with a lot of work to change stations, automatic control from the center is not performed, and another station operation management device (hereinafter referred to as a station device) is introduced. In many cases, it is controlled and operated independently. in this case,
In order to perform consistent automatic control of trains throughout the line section, it is necessary to match the daily schedule (executed schedule) between the central device and the station device. Basic daily schedules can be automatically generated from the basic patterns held in each device.However, daily changes such as temporary trains are input from terminals etc. at both the central device and station device, and the central The timetable of the equipment and the station equipment are matched.

An operation management system including such a central device and a station device is disclosed in, for example, Japanese Patent Application Laid-Open No. 8-129336.
There is a train operation management system disclosed in the issue. In this system, a central device that controls a group of relatively small stations and a station device that controls a large station are connected via a network, and the central device realizes the status of the entire line section. In the train operation management system disclosed in Japanese Patent Application Laid-Open No. 3-109169, a central device and one or more station devices are connected via a network, and a schedule held by the central device is transmitted to a station. Based on the schedule of the central unit, a method for centrally controlling the trains in the target range line section has been realized.

[0004]

SUMMARY OF THE INVENTION The above-mentioned JP-A-8-1
In the train operation management system disclosed in Japanese Patent No. 29336, the commander on the central device side can grasp the running position of the entire train, but when the train schedule is disturbed by the central device side, There is no means to automatically transmit this to the station equipment side, so the station staff at the central equipment contacts the station staff of the station where the station equipment is installed by telephone or facsimile, and the station staff at the station equipment changes the schedule information By performing the above-mentioned operation, the timetable information between the central and station devices is matched.

Further, the train operation management system disclosed in Japanese Patent Laid-Open No. 3-109169 has a function of transmitting the schedule information held in the central device to the station device. Can be automatically matched. However, the station apparatus manages the order of trains entering the area under the jurisdiction of the station apparatus based on the timetable based on the timetable. Therefore, when a train enters the jurisdiction area of the station equipment from the jurisdiction area of the central equipment, if the train that has entered the jurisdiction area of the central equipment does not match the train in the first place in the train entry order of the station equipment, incorrect control is performed. Could be done. For example, when the limited express train enters the station device from the central device, if the first train in the train order of the station device is a completely different ordinary train, an incorrect control output will be performed, and the train to which the train should arrive originally They may not be able to arrive or delay the train. Each train has a unique train number. The automatic control device keeps track of the train by constantly associating the train location information with the train number. When a returning train arrives at the station, the train number changes to another number. If the timing of updating the train number is not matched between the central device and the station device, the central device and the station device will recognize the same line as different trains.
In order to prevent this, the station equipment operator always communicates with the station operator in front and the dispatcher of the central equipment by telephone, etc.
It is necessary to match the train recognition between the central equipment and the station equipment.

In addition, there is a case where a train operator at the center wants to directly operate a traffic light or the like, because the timetable change due to traffic control cannot be made in time. At present, however, in such a case, the dispatcher of the central device contacts the operator of the station device, requests the operator of the station device to perform an operation, and performs manual control by the operator of the station.

[0007] In some cases, the central device and the station device are installed at locations separated by several hundred km or more. Usually, only a low-speed communication line is provided between the central unit and each station in the target line section.In order to transmit large-capacity information such as timetable information from the central unit to the station unit, the transmission speed is limited. A separate high-speed line is required. However, it is difficult to lay dedicated high-speed line equipment such as an optical fiber for a specific station device in terms of cost. For this reason, the use of a public line that is advantageous in terms of cost is conceivable, but in this case, when transmitting a timetable to a plurality of station devices, the central device needs to transmit a timetable to each station device. It takes a very long time to complete the transmission of the minute schedule to all station devices. Even if the diamond transmission fails for some reason, it is difficult to secure time for retransmission. Also,
There is a problem that the load on the central unit becomes very high.

SUMMARY OF THE INVENTION The present invention has been made in view of the above-mentioned circumstances, and provides a method in which a central device and a station device are connected by a low-speed line, and the entire line section including the station where the station device is installed is automatically controlled from the central device. The aim is to provide an operation management system that is capable of reducing the burden on station staff.

[0015]

Embodiments of the present invention will be described below with reference to the drawings. FIG. 2 shows an example of the overall configuration of an operation management system according to the present invention. First, the overall schematic configuration and operation will be described. The A station 62, the B station 63, and the D station 65 are small stations, and the C station 64 is a large station. Central device 1
In the same manner as the conventional centralized operation management device, the track status information of the entire line section (area) is monitored from the track circuit information 52 which is the train location information, and except for the large-scale C station 64, The control outputs 51, 66, 67 to the traffic lights 54, 55, 57 and the switches (illustrated schematically) are performed based on the schedule. The status of trains and the status of traffic lights and switches are displayed on the CRT 13 in real time. On the other hand, the station device 8 is a large-scale station C station 64 based on the track circuit information 60.
Of the train running in the area of the station device 8, and outputs control information 59 to the traffic light 56 and the switch based on the schedule in the station device 8 to perform control. The CRT 14 displays the status of the station device.

In this system, the central device 1 and the station device 8 are connected by a low-speed communication line 61. Through this line 61, the schedule of the central unit 1 and the station unit 8 is made consistent,
Continuous control is performed by the central device 1 and the station device 8. That is,
The daily schedule is created by the central device 1 including the station device 8 (if there are a plurality of station devices, all the stations) and distributed to the station device 8. In addition, traffic control desk 2
The timetable change (operation arrangement) input from 0 can be performed not only on the timetable of the central device 1 but also on the timetable of the station device 8. In this way, if the train schedule is disturbed, the central device 1 and the station device 8 can perform consistent control on the same train by using the commander of the central device 1 only by inputting from the traffic control console 20. Conversely, the traffic control input from the traffic control console 21 connected to the station device 8 is also transmitted and reflected on the central device 1.

Next, in order to continuously track the trains in the central unit 1 and the station unit 8, when the train crosses from the area of the central unit 1 to the area of the station unit 8 (from the station B 63 to the station C 6).
4 when the train moves from the station 64 to the central station 1 (from the station C 64 to the station D).
When the train moves to the station 65), a continuous train tracking is realized by exchanging a train number uniquely assigned to the train between the devices. When the train is traveling in the area of the station device 8, the station device 8 periodically transmits the train location information and the train number information to the central device 1. Thus, when the station device 8 automatically updates the train number due to a return operation, a replacement operation, or the like, the central device 1 can follow the change in the train number. The commander of the central device 1 can always correctly grasp the on-rail situation of the train.

The above-described operation will be described in detail below with regard to the detailed configuration and operation of the central device 1 and the station device 8 which are realized on a low-speed line. FIG. 1 is a block diagram showing a detailed configuration example of the central device 1 and the station device 8, and first, daily schedule transmission to the station device will be described. In the daily processing 3, a schedule is created at a regular time every day. This diagram is created for all the stations to be controlled, including the station where the station device is installed. Implementation diagram D created in this way
B2 always has four sides of the previous day, the current day, the next day, and the next two days. However, the number of days to hold the diamond is set based on the operation of the system. FIG. 3 shows the data structure of this implementation diagram, which is roughly represented by a serial number 101, train information 102 including train-specific information such as a train number and the first and last stations, and each station such as the arrival time and departure time of each station. It consists of station information 103 including unique information.

Implementation diagram DB2 created by the central unit 1
Among them, the one used in the station device is transmitted to each station device via the communication line 61 as in the flow shown in FIG. For this purpose, first, the station diagram cutout process 4 extracts the schedule related to the station having the station device from the schedule diagram DB2 and stores it in the station schedule diagram DB5 (step 40).
1). Next, in the station timetable transmission process 6, first, the train number information of the timetable to be transmitted from the station timetable DB5 is obtained and transmitted to each station device (step 40).
2). Next, the train information 102, which is transmitted in common to all stations, is transmitted by broadcast communication to each station device together with the serial number 101 (step 403). Here, the serial number 101 is a serial number. When the transmission of all the train information is completed, the transmission processing 6 transmits the station information 103 next (step 40).
4). Since the station information 103 is information for each station, only the information of the station is used for each station device.
5 and added to the serial number 101 and transmitted to the station device. In the example of FIG. 3, for example, for the station 1, only the station information 1031 related to the station 1 in the station information 103 is extracted for all trains and transmitted to the station device of the station 1. Similarly, station information 10
32 is transmitted to the station device of the station 2.

The information transmitted from the station timetable transmission process 6 of the central device in steps 402 to 404 is received by the station timetable reception process 9 of the station device. That is, first, the train information 102 and the station information 103 for the own station are assembled using the received serial number 101 as a key, and temporarily stored in the station timetable DB 10 (step 405). When the reception of all the information on the station is completed, the continuity of the serial numbers of the assembled information is checked.
s) The number of trains received from the central device is compared with the number of trains of the actual schedule actually received, and if they match (Yes in step 407), the transmission / reception processing of the actual schedule ends. As a result of the check, if the serial number is discontinuous or the number of received data is insufficient (steps 406 and 40).
No in step 7), the serial number of the discontinued schedule is transmitted to the central unit 1, and a request for resending the schedule is made (step 408). The central device 1 that has received the retransmission request displays the schedule of the serial number train in the transmission source station device in the train information 10.
2 and the station information 107 of the transmission source station apparatus 8 and the serial number 101 are transmitted as one packet as shown in FIG. The station device receives this, corrects the information of the corresponding serial number (step 405), and repeats the checks of steps 406 and 407 thereafter. When the continuity of the serial number and the number of trains are confirmed, the timetable transmission / reception processing is performed. To end.

By using the above-mentioned method for transmitting and receiving a diagram, it is possible to reduce the communication time between the central device and the station device. Therefore, a diagram transfer using a low-speed communication line to a plurality of station devices is performed. Can be realized. In addition, it is possible to prevent an increase in the load for the diamond transmission of the central unit. If the transfer of this schedule is not possible due to abnormal line, etc.,
The daily processing 19 of the station device generates an execution schedule of the station.

Next, a method of matching the Dayr between the central device 1 and the station device 8 at the time of a diagram change (driving schedule) performed when a diagram is disturbed due to a disaster or the like will be described. When the timetable is disturbed, the commander of the central device 1 performs an operation control input from the operation control desk 20 to restore the timetable, and changes the operation timetable DB2. When the operation arrangement includes a change related to the station timetable DB 10 of the station device 8, the schedule change information is transmitted from the central device 1 to the station device 8. The operation scheduling diagram cutout process 25 extracts the operation scheduling diagram related to the station device 8 from the execution schedule DB2 changed by the operation scheduling diagram input from the operation scheduling table 20. Unlike the scheduled schedule transfer at the time of day, the scheduled train schedule may include a schedule change for the train currently being controlled. On the other hand, since the traffic control schedule is change information for one train, the data amount is considerably small, and transmission can be completed in a few seconds even on a communication line with a low transmission speed. For this reason, as shown in FIG. 5, the traffic scheduling timetable transmission processing 26 sequentially performs the traffic scheduling timetable from the station device 8 which is closer to the train location, as shown in FIG.
Is transferred as a whole. The station device receives this in the traffic scheduling timetable reception process 23 and returns the serial number of the received timetable to the central device 1. In the transmission process 26, after transmitting the traffic scheduling diagram to the station device 8, if the serial number information from the reception process 23 has not been received even after waiting for a certain period of time, it is retransmitted. By doing so, it becomes possible to transmit the traffic scheduling diagram in real time even on a communication line with a low transmission speed. When the station device receives the traffic in the traffic control timetable reception process 23, it receives the data while checking whether the serial numbers are consecutive. If a non-consecutive operation scheduling diagram is received and written into the station timetable DB10, there is a possibility that a correct operation scheduling diagram may not be written. Therefore, when the reception cannot be performed with the continuous serial numbers, the rescheduling timetable reception processing 23 requests the rescheduling timetable transmission processing 26 to retransmit the rescheduled timetables after the missing serial number. Traffic control schedule transmission processing 26
, Upon receiving the retransmission request, retransmits the applicable traffic scheduling diagram. When reception is normally performed in this manner, in the traffic scheduling diagram reception process 23, the received traffic scheduling diagram is written in the station schedule diagram DB10. Thus, the traffic control input from the traffic control desk 20 is reflected on the station.

The change of the schedule (driving schedule) can also be input from the driving schedule table 21 in the station device 8. When this traffic rescheduling is performed, the station implementation schedule DB 10 is changed, and the change information is transmitted to the central device 1 in the station rescheduled schedule transmission processing 24. The central device 1 receives this in the station operation arrangement timetable reception process 27 and writes the change information in the execution timetable DB2. Also in the transmission and reception of these schedules, the serial number management is performed so that the traffic rescheduling information is transmitted correctly. By this, station implementation diamond DB1
It is possible to prevent the occurrence of a mismatch between 0 and the actual timetable DB2. It is possible to cope with a communication error or the like.

Next, transmission and reception of train numbers will be described. When the train advances from the area under the control of the central device 1 to the area under the control of the station device 8, the terminal station at the boundary of the central device 1 (the B station 63 in FIG. 1) and the final departure signal (the signal in FIG. 1) 5
5) At the timing when the train moves inside, the central unit 1
Transmits the corresponding train number from the train tracking process 28 to the station device 8 in the train number transmission process 29. This transmission timing is set at the last station (the B station 6 in FIG. 1) in the area under the control of the central unit 1.
Adjustment is made according to the length of the distance between 3) and the station (the B station 64 in FIG. 1) under the control of the station device 8. When the distance between the stations is long, the timing is not limited to the approach to the inside of the final departure signal 55, and the timing may be on the track circuit between the stations. However, it is necessary to transmit and receive the same train at a position where the central device 1 and the station device 8 do not recognize differently.

The station device 8 receives this train number in the train number receiving process 11. In the station device 8, the train entry order setting processing 17 refers to the execution schedule DB 10 to obtain the train number of the first place in the train entry order, so that this train number and the transmitted train number are used as the train numbers. Matching process 1
Compare at 2. Usually, these two train number information coincide. However, they do not match if any abnormal situation has occurred. In this case, the matching process 12 assigns the train number received from the central device 1 to the train whose entrance has been newly detected by the station device 8. At the same time, a message such as an alarm is output to the CRT 13 of the central device and the CRT 14 of the station device to notify the operator of the central device 1 and the station device 8 that an abnormal condition has occurred. When the communication between the central device 1 and the station device 8 is interrupted and the station device 8 cannot receive the train number, the train number of the first place in the train entry order of the station device 8 is subjected to the train number matching process. Select at 12. The train tracking process 15 assigns the train number selected in the train number matching process 12 to the train, and performs the train tracking. It should be noted that the method of assigning the train numbers to the trains at the time of the abnormality and the output of the alarm have constants in the central device 1 and the station device 8 and are designated according to the operation, and the operation of the train number collating process 12 is changed. Is also possible.

In the central unit, even if the authority to actually perform control is delegated to the station unit, the position of the train is notified to the commander of the central unit, and the central unit consistently obtains the running results of the train. Therefore, the train tracking process 28 also performs the train tracking for the train running in the area under the jurisdiction of the station device. on the other hand,
When a train arrives at a station and turns back to operate another train or becomes a replacement vehicle, the station device may automatically change the train number. At this time, it is necessary to correctly display the train number of the station device even in the central device, so the station device needs to periodically transmit the train location information of the train and the train number information of the existing train to the central device. is there. For this reason, in the station device 8, the train position information and train number information of the train running within the jurisdiction of the station device 8, which is grasped in the train tracking process 15, is edited in the station status information transmission process 16, and the central device 1 sends the edited information. Send. The central device 1 receives this in the station state information receiving process 33,
The same input information as that of a train running in the jurisdiction of the central unit 1 is created in the station state information receiving process 33, and the train tracking process 28
To enter. At this time, the processing is not performed under the track circuit name "1T" in the normal computer, but is performed using the equipment number uniquely assigned to the equipment. In other words, "1T"
If it is 1, 2 is used for "2T", and so on. The on-rail position information included in the station status information is also transmitted using the facility number, but the facility number may be different between the station device and the central device.
At this time, in the station state information receiving process 33, a process of converting the equipment number of the station device into the equipment number of the central device is performed. In addition,
When the communication is interrupted, an alarm is output to the CRT 13 of the central unit, and the train is tracked based on the train tracking logic of the central unit. When communication with the station device 8 is restored, an alarm is output to the CRT 13 again, and the train tracking process 28 is performed based on the station state information from the station device 8.

When a train travels from the area under the jurisdiction of the station apparatus 8 to the area under the jurisdiction of the central apparatus 1, the final departure signal on the station apparatus side (FIG. 1)
When the train moves inside the traffic light 56),
The train number is extracted from the train tracking process 15, and the train number transmission process 18 transmits the train number information to the central device 1. This transmission timing is adjusted according to the length of the distance between the area under the control of the station device 8 and the first station after the train enters the area under the control of the central device 1. When the distance between the stations is long, the timing is not limited to entering the inside of the final departure traffic light, and the timing may be on the track circuit between the stations. However, it is necessary to prevent the central unit 1 and the station unit 8 from recognizing the same train differently. In the central device 1,
The train number is received in the train number receiving process 31. Then, in the train number collating process 30, the train number information received from the station device 1 is compared with the train number information of the first place in the train entry order created in the train entry order setting process 32 from the implementation diagram inside the central device 8. I do. Usually, these two train number information coincide. However, they may not match if any abnormality has occurred. In this case, the train number received from the station device 8 is assigned to the train whose entry has been newly detected by the central device 1, and a message such as an alarm is output to the CRT 13 of the central device and the CRT 14 of the station device. This informs the operator of the central device 1 and the station device 8 that an abnormal condition has occurred. When the communication is interrupted, the first train number in the entry order of the central device is selected by the train number matching processing 30. In the train tracking process 28, the train number selected in the train number matching process 30 is associated with the train location information to track the train.

Next, a description will be given of a method of controlling a traffic signal and the like to be controlled by the station device 8 from the CRT 13 of the central device 1. When the diamond is out of order or when something abnormal occurs,
The route is manually set in the central device 1, and the switching of the switch and the traffic lights (the traffic lights 54, 55, 56, 5 in FIG. 1) are performed.
7) Control may be performed. For this reason, in the CRT 13, not only the route setting input including the traffic lights (the traffic lights 54, 55, and 57 in FIG. 1) which are the control objects of the central device 1, but also the switching device input and the station device 8 are controlled. A route setting input including a traffic light (the traffic light 56 in FIG. 1) and a switch change input are received. The accepted route setting input and the switch input of the switch are converted into an actual traffic light and a control output to the switch in the route control processing 7. In this conversion, CRT13
It is determined whether or not the input from the terminal device 8 is related to the station device 8, and the information related to the station device 8 transmits the input information from the CRT 13 from the central device 1 to the station device 8 in the manual route setting information transmission processing 34. In the station device 8, the manual route setting information receiving process 3
