Hereinafter, an embodiment of a train management system according to the present invention will be described with reference to the drawings.
FIG. 1 is a system configuration diagram showing a configuration example of the entire train management system according to the present invention.
As shown in FIG. 1, the train management system of the present embodiment includes an on-board device 10 mounted on a train, and a railway such as a traffic light 20, a turning machine, and a railroad crossing control device arranged along the track. It comprises an equipment, a station device 30 deployed at each station, a management device 40 that manages and controls the entire route including a plurality of stations. In the present specification, the “train” includes one-car trained vehicles.

The on-board device 10 is based on the wireless communication device 11, the speed generator 12 for detecting the train speed from the rotational speed of the axle, the stop position information received by the wireless communication device 11, and the detected train speed. A control device 13 that performs train speed control is provided. The control device 13 calculates the travel distance from the detected train speed, calculates the vehicle position that changes every moment, and the calculated vehicle position information and travel direction information are transmitted via the base station device by the wireless communication device 11. And transmitting to the management device 40. From the train, the travel distance information may be transmitted instead of the calculated own vehicle position information, and the position of the train may be calculated on the management device 40 side.
The control device 13 includes a calculation device such as a CPU (microprocessor) and a storage device such as a ROM or a RAM, and the ROM stores a number (train number or train number) for identifying a train. When communicating with the device 40, a train number or a train number is transmitted.

The station device 30 includes an interlocking device 31 that controls railway equipment such as a traffic light and a switch based on a signal from a track circuit (not shown) and preset interlocking chart information, and wireless communication mounted on the train. A radio base station device 32 that communicates with the device 11 and a station terminal device 33 that is connected to the interlocking device 31, the radio base station device 32, and the management device 40 by a cable.
The station terminal device 33 transmits information (position information, travel direction information) received from the on-board device 10 via the radio base station device 32 and information on the state of the traffic light 20 (lighting color) to the management device 40, The stop position information received from the management device 40 is transmitted to the on-board device 10.

The management device 40 includes a control logic unit 41 configured by a server and a command device 42 such as a personal computer. For example, as shown in FIG. 1, when the train T is traveling toward the traffic light 20 </ b> A, if it is red with reference to the state information of the traffic light 20 </ b> A, the front side of the traffic light 20 </ b> A is set as the stop position to the onboard device 10. Send stop position information. If the traffic light 20A is blue and the traffic light 20B is red with reference to the status information of the traffic lights 20A and 20B, stop position information is transmitted with the front of the traffic light 20B as the stop position.
Specifically, the management device 40 satisfies the conditions in the storage device of the control logic unit 41 on the condition of the travel section, the state of the traffic light, and the opening direction (localization, inversion) of the switch. A control logic table representing stop points at the time in a table format is stored, and stop position information is generated by referring to the control logic table and transmitted.

Next, the control procedure at the time of train travel in the train management system of the present embodiment will be described using the flowchart of FIG.
The on-vehicle device 10 side control device 13 periodically transmits its own vehicle position information (or travel distance information) and travel direction information by the wireless communication device 11 (step S1). On the other hand, the management device 40 on the ground side receives the information sent from the on-board device 10 (step S2), and if the received information is the travel distance, the train is determined from the travel distance and the starting position information. The position is calculated (step S3). Moreover, the management apparatus 40 reads the standing line information which a track circuit shows, the status information of a traffic signal, and the opening direction (localization / inversion) information of a turning machine from the interlocking device 31 of the station apparatus 30 (step S4).

  Subsequently, the management device 40 searches the control logic table for a line that matches the read condition (step S5), reads the stop position information from the stop point column of the found line (step S6), The read stop position information is transmitted to the on-board device 10 via the radio base station device 32 (step S7). Then, the on-board device 10 receives the stop position information (step S8), the control device 13 creates a control pattern (speed check pattern) (step S9), and controls the brake and the like based on the pattern (step S9). S10).

  Next, specific train control during main line travel to which the embodiment is applied will be described with reference to FIGS. Of these, FIG. 3A is a track configuration diagram showing a configuration example of a partial track in a station premises where a detention line or a garage is located, and FIG. 3B is an example of a control logic table (constant table) that is referred to when traveling on the main track. FIG. In FIG. 3 (A), the numerals preceded by the symbol “B” mean each section of the main line L divided by the traffic light. In addition, train control during main line travel is executed according to the flowchart shown in FIG.

In the line configuration diagram shown in FIG. 3 (A), there is a station platform in the range indicated by B003 in the figure, and a branching device for branching the main line L and the pulling line L0 to the detention lines L2, L3 in front of the station platform # 7 is provided, and a traffic light 21A (5R) indicating whether or not the train departs from the station platform is provided before the main line L and the pulling line L0 merge. A traffic light 21B (6R) and a branching device # 6 indicating whether or not the main line L can be entered are provided before the indwelling line L2 and the pulling line L0 merge. Corresponding to the main line L, a traffic light 21C (7L) indicating whether or not the train traveling toward the station platform (left direction in the figure) can be traveled is provided to the right of the junction.
FIG. 3B shows a control logic table in which control logic and the like when a train traveling on the main line L enters the station platform are shown.

  The vertical column on the left side of the control logic table shown in FIG. 3B is a column for entering a “block” consisting of one or a plurality of sections. A number (for example, B003) is entered. The second vertical column from the left is the column where the “traffic light” number (for example, 5R) is entered, and the third vertical column from the left is the indication of “traffic light” G (blue: progress), R (red: stop) ) Etc., the next column is a column where the branching unit number and the opening direction of the switch are entered, and the “opening direction” is entered as “localization” or “inversion”. “# 7 localization” means that the switch of the branching device # 7 in FIG. 3A is set to go to the main line L from the station platform. Also, the vertical column on the right side of the control logic table in FIG. 3B is a column where “stop point” is entered, and the position where the traveling train stops is indicated by a block number (for example, B008). It is.

  The interlocking device 31 of the station device 30 switches the indication of the traffic light 21C (7L) to red (stopped) when the train is stopped at the station platform and other trains cannot enter, and the train is moved to the station platform. When the vehicle is not stopped and entry is possible, the indication of the traffic light 21C (7L) is switched to blue (progress). Further, the interlocking device 31 controls the states (localization or inversion) of the branching devices # 6 and # 7. Such control operation by the interlocking device 31 is grasped by the management device 40 when the management device 40 acquires the states of the traffic lights 21A, 21B, and 21C and the branching devices # 6 and # 7 from the interlocking device 31. . Moreover, the management apparatus 40 grasps | ascertains a train position based on the information (a train number, a travel distance, etc.) transmitted by radio from a train.

  In this state, when a train running on the main line L comes to the block B003, the management device 40 refers to the control logic table shown in FIG. A stop point is determined from the state of 21C and the state of branching device # 7, and stop position information is transmitted to the corresponding train. Then, the on-board device 10 of the train generates a control pattern based on the received stop position information, and performs control according to the control pattern. As a result, the train can be controlled on the main line without receiving a control information signal from the ground or rail.

  Next, with reference to FIGS. 4 (A) and 4 (B), the train control when the above embodiment is applied and the train is replaced in the station premises having the indwelling line will be described. Among these, FIG. 4 (A) is a track configuration diagram showing an example of the configuration of a partial track in a station premises where there is an area (detained line) where train replacement is performed, and FIG. 4 (B) is a management device 40 at the time of replacement work. It is a figure which shows the example of the control logic table (constant table) referred by. In FIG. 4 (A), the numerals preceded by the symbol “@” mean each section in which the vehicle presence line can be identified. Moreover, the train control at the time of replacing trains is also executed according to the flowchart shown in FIG.

  In the track configuration diagram shown in FIG. 4 (A), the pulling line L0 is between the premise area A1 and the main line area A2 where the train waits, and the premise area A1 is connected to the branching units # 7 and # 7 from the pulling line L0. The main line L1, branch line L2 and detention line L3 branching through 6 are laid, and a platform is provided between L1 and L2, and a traffic light 21A indicating whether or not the train can proceed before L1 and L2 merge. 21B is provided. Further, at the end of the main line area A2, a traffic light 21C indicating whether or not the entry to the pulling line L0 is possible is provided. On the other hand, the detention line L3 used for train replacement is not provided with a traffic light.

Next, a train replacement operation using the pulling line L0 and the detention line L3 in the campus area shown in FIG. 4A will be specifically described.
Here, description will be made assuming that the target train enters the main line L from the detention line L3 through the pulling line L0, stops before the traffic light 21C, and returns to the detention line L3 again. In addition, the control at the time of this replacement | exchange is started, for example by operating the replacement lever (switch) in the instrument box installed in the vicinity of branching device # 6.

  When the switch is operated, the interlocking device 31 switches the traffic lights 21A, 21B, and 21C to the stop display, and prohibits other trains from entering the area. Such a control operation by the interlocking device 31 is grasped by the management device 40 when the management device 40 acquires the states of the traffic lights 21A to 21C and branching devices # 6 and # 7 from the interlocking device 31.

FIG. 4B shows a control logic table in which control logic for stopping a train that has left the section @ 03 of the indwelling line L3 in a section @ 07 before the traffic light 21C is described.
The vertical column on the left side of the control logic table shown in FIG. 4B is a column in which “route” is entered, and is the starting point of the track circuit number (eg, @ 03) as the starting point. The track circuit number (for example, @ 07) is entered. The second vertical column from the left is the column where the station number is entered (for example, 741), the next column is the column where the branch number and the opening direction of the switch are entered. “Direction” or “displacement” is entered as “direction”. The “# 6 inversion” and “# 7 inversion” are set so that the branching devices # 6 and # 7 in FIG. 4 (A) have the train route from the detention line L3 to the main line L via the pulling line L0. It means that

  The vertical column on the rightmost side in the control logic table shown in FIG. 4B is a column in which “stop point” is entered, and the position where the train stops at the time of replacement work is the track circuit number. (For example, @ 07), the management device 40 refers to the control logic table of FIG. 4B, and if the conditions of “route”, “station handling”, and “opening direction” match, “stop” The point information is transmitted to the on-board device 10 of the corresponding train, and the on-board device 10 executes the brake control according to the information when the train reaches the stop position.

  Note that the second “hold” column from the right in the control logic table of FIG. 4B is a column in which the holding conditions are entered. When the exchange starts, the train position information does not match the starting point due to the movement of the train, so the above condition does not hold, but the condition entered in the “Hold” column is retained thereafter. Thus, for example, if “@ 06” is entered in the “Hold” column, the train reaches this position, and other conditions are “station handling” and “opening direction”. If the above conditions match, the management apparatus 40 can transmit “@ 07” as “stop point” information even if the train position does not match the departure point.

By the way, in the section where there is no traffic light, such as the detention line L3 and the pulling line L0 shown in FIG. 4A, for example, the train is stopped at the section @ 06 before the landing section @ 07, and the traveling direction is reversed. In some cases, the work returns to the indwelling line L3. In this embodiment, assuming such a case, “@ 06- @ 03” is entered in the “route” in the control logic table of FIG. In each of the “opening direction” fields, the numbers “741” and “# 6 inversion” are entered, and the logic in which the section @ 03 is entered as the “stop point” is provided.
As a result, even if the originally scheduled work (turnback at section @ 07) is changed and the work is turned back at section @ 06, the management device 40 refers to the control logic table and displays information “03” of “stop point”. It can be transmitted to the on-board device 10. Therefore, it is possible to respond flexibly while ensuring safety.

As mentioned above, although embodiment of this invention was described, this invention is not limited to the said embodiment, A various deformation | transformation and change are possible. For example, in the above embodiment (FIG. 4), the premises area where L1 is a main line, L2 is a side line, and L3 is a detention line, L1 to L3 are all detention lines, as shown in FIG. The present invention can also be applied to an area where L2 and L3 are indwelling lines and L1 is a main line.
In the above-described embodiment, the interlock device 31 is provided in each station, and the control logic unit 41 of the management device 40 has shown the system in which the status information of the traffic lights along the line and the switchboard is obtained from the interlock device 31. A system in which the control logic unit 41 of the apparatus 40 directly controls railway equipment such as traffic lights and turning machines is also possible. In this case, the control logic unit 41 itself grasps the state of each equipment, There is no need to acquire state information from the interlocking device. Furthermore, one interlocking device 31 may be provided for a plurality of stations.

In the above embodiment, it has been described that the train position information is obtained by calculating from the starting point information and the travel distance. However, a ground element that transmits information for position correction along the track is arranged at an appropriate distance. You may make it install. It is also possible to install a GPS (Global Positioning System) device on the train and transmit the position information acquired from the GPS device instead of the travel distance.
Furthermore, data transmission / reception between the on-board device 10 and the ground side management device 40 may be performed by communication using an LCX cable (leakage coaxial cable).
