Description

  The present invention relates to a course control system, a course control method, and a ground device. In particular, the present invention relates to a tram that is a means of transportation in a relatively small area called a tram or light rail applied to urban traffic.

  Conventionally, there is a tram as a means of transportation in a relatively small area such as in a city. Recently, trams are sometimes referred to as trams and light rails, and in addition to being cheaper to introduce than subways and monorails, by traveling on trams, cars traveling around It is a means of transportation that is relatively unaffected by these means of transportation. For this reason, trams are expected to alleviate traffic congestion in cooperation with automobiles and route buses, and are being introduced in countries around the world including Japan.

  A tram runs along a track laid on the road. Therefore, when it is necessary to determine a destination such as a T-junction or a crossroad, the trajectory must be formed so as to be able to travel in a predetermined direction by changing the turning machine installed at the branch point. In particular, there are cases where trajectories called “chiasus” intersect at places that need to be turned back at a terminal station or an intermediate station.

  There is a risk of derailment if the switch is changed while the tram is on the switch. Therefore, there is a need for a method for detecting the presence of a tram in a certain section including a switch. Here, a certain section including the switch is referred to as a lock-and-lock section, and a method of detecting the presence of a tram in the lock-and-lock section is referred to as train detection in the lock and lock section.

  Regarding the train detection in the locked lock section, there are techniques described in Japanese Patent Application Laid-Open No. 2004-58969 (Patent Document 1) and Japanese Patent Publication No. 6-29026 (Patent Document 2). The technology disclosed in Patent Document 1 relates to a tramway switch control system, and more particularly to improvement of a switch control at a branch point of a tramway track. It was made for the purpose of performing it automatically without relying on the judgment of. Among these, an optical beacon, which is one of the transmission / reception units provided immediately before the entrance of the branch point, is used to determine whether or not it has passed through the branch point entrance. The tram detects the approach of the tram to the locked lock section by receiving the vehicle ID that is continuously transmitted after the passage of the optical beacon. In addition, the control unit of the ground device is one of the transmission / reception units, and receives the vehicle ID that the tram continues to transmit via the optical beacon arranged at the branch point exit, thereby the branch region. Detect the advance of.

  On the other hand, the technique disclosed in Patent Document 2 relates to a ground device of a train control device that performs train detection by a check-in / check-out method or a check-in / reset method. It is possible to determine from which point a train has entered, and for the purpose of stopping control to the correct train when another train enters even though the correct train is traveling in the correct direction. The point detection check-in and check-out type train detection devices are exemplified, and a method of detecting trains in the section by the reception loops installed at the entrance and exit of the locked lock section is disclosed. Has been.

JP 2004-58969 A Japanese Patent Publication No. 6-29026

  There is a check-in / check-out method as conventional train detection. The check-in / check-out method is to install a device that detects the passage of a train at a predetermined point and install a device that detects the passage of a train at another predetermined point. When the passage of a train is detected at a certain point, it is determined that the train is present in a section divided into two points. In addition, if the train passes through any point after determining the presence of the train, it is determined that the train is not present. This means that if there is no branch in the section, the train can be detected by a relatively simple method.

  Patent Document 1 discloses a method for implementing train detection in a certain section by mounting a device that transmits a vehicle ID to a train and installing a beacon that receives the vehicle ID on the ground.

  In Patent Document 2, for each entry point of the train to the closed section, a track storage means for storing that the train has entered the closed section is provided to determine from which point the train has entered, When other trains enter the closed section while a regular train is in progress and a plurality of track storage means store the train approach, a signal corresponding to the stop indication of automatic train control is sent to the closed section. Since it is the structure which transmits and stops control of a regular train, the security of train control when two trains enter the same closed section can be improved.

  Patent Document 1 and Patent Document 2 disclose a check-in / check-out implementation method when there is a branch in a section, but do not clearly show a train detection method in Caesus.

  Caesus refers to the configuration of a track that is laid for the purpose of replacing streetcars between a plurality of lines when a double-track line is laid, and has an intersection. In a double-track route, even if there is a tram that goes straight on one route, it must not interfere with the straight-line operation of the tram on the other route. In addition, when a streetcar is switched from one route to the other, a route for another streetcar must not be configured within the section. In the methods of Patent Document 1 and Patent Document 2, when a device for detecting the passage of a tram is mounted at the entrance and exit of a certain section, and the passage of the tram is detected by any device, the tram is Although it is possible to determine that the track is in a certain section and to prevent other streetcars in this section from being routed, it is possible to prevent a tramway that goes straight on one route in a track configuration like Caesus. In some cases, a method for controlling the route so as not to hinder the operation of the tram on the other route is not disclosed.

  It is an object of the present invention to provide a path for a tram traveling on one track for a section including a plurality of switches installed at a branch point of a pair of tracks, and at least one of the configured paths. This is to prevent the route including the overlapping part from being configured as a route for the tram traveling on the other track.

  In order to solve the above-mentioned problems, the present invention provides a plurality of installed respectively at a plurality of branch points for connecting each track and a plurality of branch tracks among a pair of tracks constituting a traveling road of a tram. And a plurality of traffic lights installed on the tram entrance side in the area including the plurality of turning machines in the track and in the vicinity of the lock-and-lock section centering on the section. , A ground device for controlling the switch and the traffic light, transmission means for receiving the route control information transmitted from the on-board device mounted on the tram, and transmitting the received route control information to the ground device; An on-line detecting device that detects presence / absence of the presence of the tram in the lock-and-lock section and transmits detection information to the ground device, and the ground device is transmitted from the transmission means. The route control The turning machine is controlled in accordance with the route instructed in the information, the route instructed in the route control information is configured, and the route instructed in the route control information is provided on condition that the route is configured. Comparing the on-line management information defined as the status of the on-line detection device with the detection information transmitted from the on-line detection device, and if the comparison result is normal, the control on the traffic light is allowed to proceed, When the comparison result is abnormal, the control on the traffic light is not allowed to proceed.

Embodiments of a route control system according to the present invention will be described below with reference to the drawings.
The following examples show specific examples of modes for carrying out the present invention, and the present invention is not limited to these examples, and is based on the technical idea disclosed in this specification. Various changes and modifications can be made by those skilled in the art within the scope.

  In all the drawings for explaining the embodiments, the same reference numerals are given to those having the same function, and the repeated explanation thereof may be omitted.

  FIG. 1 is a schematic configuration diagram of a route control system in which the present invention is applied to Caesus (Chisas Crossing, Double Crossing) which is an example of a tramway branch. In particular, Caesus is a crossover where two crossing tracks (tracks) are arranged with diamond crossings that can cross both tracks, and a switch is provided at the four contact points between the two tracks and the diamond crossings. Say the orbital structure. The present invention has a plurality of tracks on which a vehicle travels, and in a track configuration that can travel (cross) between tracks, there is a track that is not affected by the travel of the vehicle depending on the course of the vehicle. Focusing on the existing points, it aims to improve the efficiency of operation.

  In FIG. 1, the course control system includes a detection loop 20, traffic lights 30, 31, a switch 40, 41, 42, 43, a ground device 50, a display terminal 51, short trajectory circuits 60, 61, 62, 63 and a track circuit device 64. The detection loop 20 is disposed between the tracks 12 and 13 constituting the travel path of the tram 10, connected to the ground device 50, and mounted on the tram 10 that travels on the tracks 12 and 13. 11 is configured as a narrow area wireless transmission means for receiving the route control information transmitted from the reception antenna 11 (not shown) and transmitting the received route control information to the ground device 50. At this time, the on-board device 11 can transmit the route control information to the ground device 50 in the range of several meters before and after the detection loop 20. Instead of the detection loop 20, a wireless local area network (LAN) can be used.

  The traffic lights 30, 31 are sections including the respective turning machines 40, 41, 42, 43 in the tracks 12, 13 constituting the traveling path of the tram 10, and the lock-lock section having the section as the center. It is installed on the streetcar entrance side or streetcar exit side in the area near 14 respectively. Each of the rolling machines 40, 41, 42, 43 has a plurality of branching tracks (branching tracks crossing each other at the center of the lock-and-lock section 14) among the tracks 12, 13. It is installed at each of a plurality of branch points for connection. The ground device 50 is composed of a computer device having information processing resources such as a CPU (Central Processing Unit), a memory, and an input / output interface, and is connected to the display terminal 51. In addition to displaying the status and control results on the display terminal 51, it also has a log storage mechanism. If an accident occurs, the control results of the ground device 50 are verified retroactively and the verification results are displayed. It can be displayed on the terminal 51.

  The ground device 50 includes traffic lights 30 and 31 installed on the streetcar entrance side or streetcar exit side in the vicinity of the lock and lock section 14, and branch points (tracks 12 and 13 of the track and lock section 14). It is connected to the switches 40 to 43 installed at the branch point), and the traffic lights 30, 31 and the switches 40 to 43 can be controlled. The ground device 50 performs the conversion of the turning machines 40 to 43 in accordance with the instructions recorded in the route control information transmitted from the on-vehicle device 11. The traffic lights 30 and 31 installed at the entry end of the lock-and-lock section 14 turn on a signal for indicating whether or not the road-car 10 can enter the lock-and-lock section 14. At this time, in order for the traffic lights 30 and 31 to turn on the green light and indicate that the travel is possible, the locks (locks) of the rotary machines 40 to 43 are a condition. For example, a driver who has boarded the tram 10 drives the tram 10 in accordance with the indication of the traffic light 30. When the traffic light 30 lights up a green light, the driver 10 enters the locked section 14 by checking the tram 10. Let it enter.

  The ground device 50 is connected to the short track circuits 60 to 63 via the track circuit device 64, and detects the presence of the tram 10 in the lock and lock section 14. The short and small track circuits 60 to 63 include a small section track (four small section tracks) in the lock section 14 of the tracks 12 and 13 constituted by two rails, and both ends of each small section track. It is comprised from the electrical insulator inserted in (both ends of each rail which comprises a small section track). When a loop current flows between the axle of the tramway 10 and the small section track (two rails) constituting the short trajectory circuit 60, the trajectory circuit device 64 has the tramway 10 on the short trajectory circuit 60. It detects that there is a line, and transmits this line detection (detection information) to the ground device 50. Similarly, the track circuit device 64 detects that the streetcar 10 is present on each of the short track circuits 61 to 63 and transmits each track detection (tracked line information) to the ground device 50. At this time, the track circuit device 64 and the short track circuits 60 to 63 constitute a standing line detection device that detects the presence or absence of the track line in the locked section 14, and the short track circuits 60 to 63 are located lines. Configure the detection means.

  At this time, the short track circuits 60 and 61 are arranged in the lock and lock section 14 so as to sandwich the switch machines 40 and 41 installed on the track 12. In the lock and lock section 14, the rolling machines 42 and 43 installed on the track 13 are sandwiched. In this way, each of the short track circuits 60 to 63 is configured as first to fourth on-line detection means for detecting entry or exit of the tramway to the lock and lock section 14.

  As each line detection means, other line detection means such as a loop coil or an accelerator counter laid in the lock-lock section 14 may be used. The loop coil laid in the lock-and-lock section 14 indicates that when the tram 10 travels through the lock-and-lock section 14, the presence of the tram 10 in the lock-and-lock section 14 due to a change in the magnetic field. Can be detected. The accelerator counter is laid on the tracks 12 and 13 in the lock and lock section 14 and counts the axle of the tram 10 passing on the tracks 12 and 13 in the lock and lock section 14. From this count value, the presence line of the tram 10 in the locked lock section 14 can be detected. In addition, based on the detection result of a standing line detection means, the check lock of the rolling mills 40-43 is implemented.

FIG. 2 (A) shows a short track circuit and a configuration block in the lock-and-lock section. FIG. 2B is a configuration diagram of a management table managed by the ground device.

  In FIG. 2A, in the ground device 50, with respect to the course of the tram 10 in the locked section 14, the course 1 with the short track circuit 60 as the start point and the short track circuit 61 as the end point, The path 2 starting from the track circuit 63 and ending with the short track circuit 62, the path 3 starting from the short track circuit 60 and ending with the short track circuit 63, and the path starting from the short track circuit 63 And the route 4 is managed with the short track circuit 60 as an end point. At this time, the short orbit circuits 60 to 63 in the lock and lock section 14 serving as a cesius are logically divided into two blocks 70 and 71 and managed. The short track circuits 60 and 61 belong to a block (first block) 70, and the short track circuits 62 and 63 belong to a block (second block) 71. Further, the short trajectory circuits 60 to 63 indicate that the tram 10 or 15 has been on the line when the tram 10 or 15 enters the lock and lock section 14 from outside the lock and lock section 14. Is detected as a check-in track circuit. When the tram 10 or 15 travels from the inside of the lock and lock section 14 to the outside of the lock and lock section 14, the tram 10 or 15 When detecting that there is a line, it functions as a checkout track circuit.

  In FIG. 2B, the management table 100 is a table stored in the memory of the ground device 50, and includes a route name field 110, a check-in track circuit field 120, a check-out track circuit field 130, and a first. It comprises a configuration block field 140 and a second configuration block field 150. Information (data) recorded in the management table 100 is used for forced on-line determination and on-line determination as will be described later.

  In each record of the route name field 110, information related to a name that specifies the route of the tram 10 or 15 in the lock and lock section 14 is recorded. For example, “Route 1” to “Route 4” are recorded in each record of the route name field 110.

  Each record in the check-in track circuit field 120 stores the names of check-in track circuits corresponding to “track 1” to “track 4” recorded in the record in the track name field 110. For example, “short track circuit 60” is recorded as a check-in track circuit corresponding to each of “track 1” and “track 3”, and check-in track circuits corresponding to “track 2” and “track 4”, respectively. “Short orbit circuit 63” is recorded.

  In each record of the checkout track circuit field 130, names of checkout track circuits corresponding to “track 1” to “track 4” recorded in the record of the route name field 110 are stored. For example, “short track circuits 61, 62, 63, 60” are sequentially recorded as checkout track circuits corresponding to each of “tracks 1 to 4”.

  In each record of the first component block field 140, the names of the first component blocks belonging to “route 1” to “route 4” recorded in the record of the route name field 110 are recorded. For example, “Route 70” is recorded as “First route” to which “Route 1” and “Route 3” belong, and “Block 71” as “First route” to which “Route 2” and “Route 4” belong. Is recorded.

  In each record of the second component block field 150, the names of the second component blocks belonging to “route 1” to “route 4” recorded in the record of the route name field 110 are recorded. For example, since “No. 1” and “No. 2” do not have the second constituent block to which they belong, “None” is recorded, while “No. 3” and “No. 4” are the second constituent blocks to which “Block 71” and “Block 70” are recorded, respectively.

  FIG. 3 is a diagram for explaining the relationship between the course in the lock-and-lock section and the state of each facility, and FIG. 3 (A) shows the short track circuit and the configuration block in the lock-and-lock section. FIG. 3B is a configuration diagram of a management table for managing the state of each facility in the locked lock section.

  FIG. 3A shows a state in which “Route 1” is set as a route for the tram 10, and the tram 10 is on the short track circuit 60 in the lock and lock section 14.

  The management table 200 is a table for managing the state of each facility in the lock and lock section 14, and includes a facility field 210 and a state field 220. In each record of the equipment field 210, the name of each equipment in the lock and lock section 14 is recorded. For example, “short track circuit 60” to “short track circuit 63”, “block 70” to “block 71”, and “route 1” to “track 4” are recorded in each record of the equipment field 210.

  Each record in the state field 220 is information indicating the state of the equipment recorded in each record in the equipment field 210, and the presence line detection information defined as the state of each short track circuit 60 to 63 corresponding to the course. Is recorded. For example, when “Route 1” is configured as a route and the tram 10 is in a region including the short track circuit 60, “Standing” is recorded as the state of the short track circuit 60, and the short track circuits 61 to 63 are recorded. As a state of "No Line" is recorded. Further, when “track 1” is configured as the route to the tram 10, the “tracking” is recorded in the block 70 as the track management information for the blocks 70 and 71, and the “non-track” is stored in the block 71. Is recorded. Further, when “Route 1” is configured as a route for the tram 10, “Set” is recorded in the record corresponding to “Route 1” among the records in the status field 220, and “Route 2”. In the record corresponding to “path 4”, “not set” is recorded.

  When “Route 1” is set as the route for the tram 10, “On-line” is recorded on “Block 70”, and “Non-on-line” is recorded on “Block 71”, the starting point is In the short track circuit 63, the “path 2” whose end point is the short track circuit 62 can be configured. In this case, in the lock-and-lock section 14, “Route 1” and “Route 2” are not routes that compete with each other, and can be set at the same time, and can be set at the same time. It is possible to pass the tram on the "route 2" route.

  When “Route 1” is set as the route for the tram 10, the CPU of the ground device 50 transmits the route transmitted from the detection loop 20 before the tram 10 enters the lock block section 14. The turning machines 40 and 43 are controlled in accordance with the route indicated by the control information to form the route 1 (first route) indicated by the route control information, and on the condition that the route 1 is configured, the route control information Corresponding to the instructed “course 1”, the status of the standing line detection device, that is, the information defined as the status of each of the short track circuits 60 to 63, which is information on the standing line management information (“ The present line is compared with the detection information ("present line (present line)" or "no present line (non-present line)") transmitted from each of the short track circuits 60 to 63. Match and comparison result is normal That case, the progress-friendly control over traffic 30 and 31, a content of both mismatch, if the comparison result is abnormal, and not proceed control over traffic 30 and 31.

  When “Route 1” is set as the route to the tram 10, the CPU of the ground device 50 uses the short track circuit (first in-line) when the tram 10 enters the locked lock section 14. Detecting means) Record the track as the track management information for the track 60, record the track tracking as the track management information for the other short track circuits 61, 62, 63, and from the locked section 14 of the tram 10 The standing line is recorded as the standing line management information for the short track circuit 61 at the time of exit, and the non-tracking line is recorded as the standing line management information for the other short track circuits 60, 62, 63. In the course of traveling along, the in-line management information recorded in the management table 200 and the detection information of each short track circuit 60 to 63 are compared, and it is determined whether or not the contents of both match.

  FIG. 4 is a diagram for explaining the relationship between the course in the lock-and-lock section and the state of each facility, and FIG. 4 (A) shows the short track circuit and the configuration block in the lock-and-lock section. FIG. 4B is a configuration diagram of a management table for managing the state of each facility in the locked lock section.

  In FIG. 4A, “Course 3” is set as the course for the tram 10, and the tram 10 is on the short track circuit 60 in the lock and lock section 14.

  The management table 200 is a table for managing the state of each facility in the lock and lock section 14, and includes a facility field 210 and a state field 220. In each record of the equipment field 210, the name of each equipment in the lock and lock section 14 is recorded. For example, “short track circuit 60” to “short track circuit 63”, “block 70” to “block 71”, and “route 1” to “track 4” are recorded in each record of the equipment field 210.

  Each record in the state field 220 is information indicating the state of the equipment recorded in each record in the equipment field 210, and the presence line detection information defined as the state of each short track circuit 60 to 63 corresponding to the course. Is recorded. For example, when “Route 3” is configured as a route and the tram 10 is in a region including the short track circuit 60, “Standing” is recorded as the state of the short track circuit 60, and the short track circuits 61 to 63 are recorded. As a state of "No Line" is recorded. Further, when “track 3” is configured as the route to the tram 10, the “tracking” is recorded in the block 70 as the track management information for the blocks 70 and 71, and the “track” is stored in the block 71. To be recorded. Further, when “Route 3” is configured as a route for the tram 10, “no setting” is recorded in the records corresponding to “Route 1” to “Route 2” among the records in the state field 220. , “With setting” is recorded in the record corresponding to “Course 3”, and “No setting” is recorded in the record corresponding to “Course 4”.

  When “Course 3” is set as the course for the tram 10, “On-line” is recorded for “Block 70”, and “On-line” is recorded for “Block 71”, the starting point is a short orbit. In the circuit 63, the “track 2” whose end point is the short track circuit 62 or the “track 4” whose start point is the short track circuit 63 and whose end point is the short track circuit 60 is the first building block 140 or the second Since “block 70” or “block 71” in which “present line” is recorded exists in the configuration block 150, the configuration cannot be performed. Further, since “Route 2” and “Route 4” are routes competing with each other for “Route 1”, “Route 1” cannot be configured by disabling simultaneous setting. Note that “course 1” cannot be configured because “block 70” in which “present line” is recorded exists in the first configuration block 140. As described above, when “Route 3” is set as the route for the tram 10, and “On-line” is recorded for “Block 70” and “Block 71”, only “Route 3” can be configured. By disabling “Route 1”, “Route 2”, and “Route 4”, it is possible to avoid the configuration of routes in which the tram 10 may collide with other trams, Safety can be ensured.

  At this time, when “Route 3” is set as the route to the tram 10, the CPU of the ground device 50 is located on the short track circuit 60 when the tram 10 enters the locked lock section 14. The track is recorded as management information, the track is recorded as track management information for the other short track circuits 61, 62, 63, and the short track circuit when the tram 10 leaves the locked lock section 14 is recorded. In the process in which the track is recorded as the track management information for 63, the track is recorded as the track management information for the other short track circuits 60, 61, 62, and the tram 10 travels along the "track 3" Then, the on-line management information recorded in the management table 200 is compared with the detection information of the short track circuits 60 to 63, and it is determined whether or not the contents of the two match.

  When “Route 2” is set as the route to the tram 10, the CPU of the ground device 50 manages the on-line for the short track circuit 63 when the tram 10 enters the locked lock section 14. As the information, the standing track is recorded, the non-tracking track is recorded as the standing track management information for the other short track circuits 60, 61, 62, and the short track circuit 62 when the tram 10 leaves the locked lock section 14 is recorded. In the process in which the track is recorded as the track management information for the track, the track tracking is recorded as the track management information for the other short track circuits 60, 61, 63, and the tram 10 travels along the "track 2" The on-line management information recorded in the management table 200 is compared with the detection information of each of the short track circuits 60 to 63, and it is determined whether or not their contents match.

  Further, when “Route 4” is set as the route to the tram 10, the CPU of the ground device 50 manages the current track for the short track circuit 63 when the tram 10 enters the locked lock section 14. As the information, the standing track is recorded, the non-tracking track is recorded as the standing track management information for the other short track circuits 60, 61, 62, and the short track circuit 60 when the tram 10 leaves the locked lock section 14 is recorded. In the process of recording the track as the track management information for the track, recording the track tracking information as the track management information for the other short track circuits 61, 62, 63, and the tram 10 traveling along the "track 4" The on-line management information recorded in the management table 200 is compared with the detection information of each of the short track circuits 60 to 63, and it is determined whether or not their contents match.

  The CPU of the ground device 50 manages the block 70 including the short orbit circuit 60 and the short orbit circuit 61 as the first block, and manages the block 71 including the short orbit circuit 62 and the short orbit circuit 63 as the second block, and the road surface. When “Route 1 (first route)” is configured as a route for the train 10, when the streetcar 10 enters the check lock section 14 and from the check lock section 14 of the tram 10. As a track management information (block management information recorded in the management table 200) for the block 70 at the time of leaving, a track is recorded, as a track management information for the block 71, a non-track is recorded, and as a course for the tram 10, When “Route 2 (second route)” is configured, when the tram 10 enters the lock-and-lock section 14 and from the lock-and-lock section 14 of the tram 10 As the track management information for the block 70 at the time of exit, a non-tracked track is recorded, the track is recorded as the track management information for the block 71, and “track 3 (third track)” is configured as the track for the tram 10. In this case, the standing line is recorded as the standing line management information for the block 70 when the tram 10 enters the lock-and-lock section 14 and when the tram 10 leaves the lock-and-lock section 14. As the track management information for the track, the track is recorded, and when “track 4 (fourth track)” is configured as the track for the tram 10, when the tram 10 enters the check lock section 14 and As the track management information for the block 70 when the tram 10 leaves the locked lock section 14, the track is recorded, and the track management information for the block 71 In the process in which the track is recorded and the tram 10 travels in the locked lock section 14, the track management information recorded in the management table 200 and the detection information of each of the short track circuits 60 to 63 are compared. To do.

  In other words, the tram 10 has its own logical block on its own route, and when all the so-called “occupation rights” can be acquired, the route control is permitted, and any one of its own routes on the route is obtained. Even in the logical block, if it is already “on-line” and the occupancy right cannot be acquired, the configuration cannot be made, and safety can be ensured by prohibiting entry into the locked lock section. Therefore, in the case where a path in which logical blocks do not overlap each other is set so as to pass through each of the parallel tracks, there is no safety problem even if two vehicles exist simultaneously in the locked and locked section. The vehicle can be operated efficiently.

  FIG. 5 is a configuration diagram illustrating a display example of the display terminal. In FIG. 5, information input from the track circuit device 64 is displayed on the display screen 52 of the display terminal 51. For example, when information indicating that the state of the short track circuit 60 has changed from “not present” to “present” is input from the track circuit device 64, “20” is displayed on the display screen 52 of the display terminal 51. : 56: 38.618 Track circuit (input) The equipment type (short track circuit 60) change (non-existing line → present line) is displayed, and the alarm that the forced standing line has occurred in the logic block 70 is displayed from the track circuit device 64. When the information to be displayed is input, “20: 56: 38.625 alarm forced on-line generation occurrence facility (logic block 70)” is displayed on the display screen 52 of the display terminal 51.

  FIG. 6 is a flowchart showing the flow of forced on-line determination processing of the ground device. This process is started when the CPU of the ground device 50 starts a forced standing line determination processing program stored in the memory.

  Here, the ground device 50 configures a route according to the instruction content of the route control information transmitted by the on-board device 11. After the completion of the course configuration, if a short track circuit other than a predetermined check-in track circuit detects an on-line, an approach other than the tram 10 equipped with the on-board device 11 or a short track circuit failure Alternatively, since the failure of the track circuit device 64 is considered, in any case, the system is in an abnormal state. For this reason, after the course configuration is completed, if a short track circuit other than a predetermined check-in track circuit detects a track, it is compulsory to ensure safety in the lock section 14. Therefore, even if the path is configured with the check-and-lock section 14 being in the on-line state, control is performed so that the traffic signal 30 and the traffic signal 31 are not displayed as progress. This function is called forced presence line determination.

  First, when the route control information transmitted from the on-board device 11 is received from the detection loop 20, the CPU of the ground device 50 determines whether or not there is a route setting in the received route control information (S11). . When it is determined in step S11 that there is no setting of the course, the CPU of the ground device 50 determines whether any of the short track circuits 60 to 63 has detected the presence line (there is a presence line) (S12). If the CPU of the ground device 50 determines in step S12 that none of the short track circuits 60 to 63 has detected a presence line (no presence line), it is determined that there is no presence line in the locked lock section 14, and this routine is processed. If any of the short track circuits 60 to 63 is determined to be in-line detection (with in-line) in step S12, it is abnormal that the in-line is detected even though there is no course setting, so forced in-line The presence setting is performed (S13). At this time, the CPU of the ground device 50 puts the constituent blocks (blocks 70 and 71) of the lock and lock section 14 in a state where there is a forced presence line, and thereafter ends the processing in this routine. As a result, control is realized in which the course including the blocks 70 and 71 set in a state where there is a forced presence line is not displayed as a progress. For example, the CPU of the ground device 50 cannot forcibly advance the control on the traffic lights 30 and 31 when any of the short track circuits 60 to 63 detects the presence of a track before the course designated by the course control information is formed. And

  On the other hand, when it is determined in step S11 that the route is set, the CPU of the ground device 50 configures the route according to the instruction content of the received route control information, and determines whether or not the presence line detection is performed by an unauthorized short track circuit. Determination (determination of presence / absence of an illegal short track circuit) (S14). Here, the presence of an illegal short track circuit means that if a short track circuit other than the check-in track circuit is present when the check-in track circuit has not detected any track after the course configuration, or the check-in track After the circuit is configured, the check-out track circuit becomes non-existing when it becomes a non-existing line after changing to a non-existing line after changing to a non-existing line. Or a short track circuit that is neither a check-in track circuit nor a check-out track circuit becomes a track.

  If it is determined in step S14 that there is no illegal standing line, the CPU of the ground device 50 ends the processing in this routine, assuming that the standing line in the locked lock section 14 is normal with respect to the route.

  On the other hand, if it is determined in step S14 that there is an illegal presence line, the CPU of the ground device 50 sets the presence line in the locked lock section 14 to be abnormal with respect to the course, and sets forcible presence line (S15). . At this time, the CPU of the ground device 50 puts the constituent blocks (blocks 70 and 71) of the lock and lock section 14 in a state where there is a forced presence line, and thereafter ends the processing in this routine. As a result, control is realized in which the course including the blocks 70 and 71 set in a state where there is a forced presence line is not displayed as a progress.

  FIG. 7 is a flowchart showing the flow of the presence line determination process of the ground device. This processing is performed when the processing ends with the determination result that there is no forced presence line in the forced presence line determination processing (when it is determined that there is no presence line in Step S12 or when it is determined that there is no unauthorized presence line in Step S14). The 50 CPUs are started by activating an on-line determination processing program stored in the memory.

  First, the CPU of the ground device 50 refers to the state of the blocks 70 and 71 of the management table 220 to determine whether or not there is no previous line (S21). It is determined whether or not the detection information of any check-in track circuit belonging to the route that has been changed has changed from a non-present line to a present line (S22). If it is determined in step S22 that there is no change, since there is no existing line this time following the previous time, the CPU of the ground device 50 sets no existing line (S23), and then the processing in this routine is terminated.

  On the other hand, if it is determined in step S22 that there is a change, the CPU of the ground device 50 sets the presence of the presence line, assuming that the presence of the streetcar 10 is detected by any check-in track circuit belonging to the set route (S24). Then, the processing in this routine is terminated.

  If it is determined in step S21 that there is a previous track, that is, if the previous check-in track circuit detects the presence of the tram 10, the CPU of the ground device 50 checks any of the checkout tracks belonging to the set route. It is determined whether the detection information of the circuit has changed from a standing line to a non-present line (S25). When it is determined that there is no change in step S25, the tram 10 is assumed to be present between the check-in track circuit and the check-out track circuit, and the CPU of the ground device 50 sets presence of the present track (S26). Thereafter, the processing in this routine is terminated.

  On the other hand, if it is determined in step S25 that there is a change, that is, if the detection information of any checkout track circuit belonging to the set route has changed from the present line to the non-present line, the tram 10 will check the checkout track circuit. Therefore, the CPU of the ground device 50 sets no standing line (S27). In this case, the tram 10 has already passed through the area of the check-in track circuit and the area of the check-out track circuit, and the detection information of the check-in track circuit and the check-out track circuit are respectively non-existing lines. The 50 CPU sets a non-existing line, and then ends the processing in this routine.

  At this time, when “route 1” is configured as a route for the tram, the CPU of the ground device 50 records the standing line as the standing line management information for the block 70 (first block), and the block 71 (second block). A non-existing line is recorded as the on-line management information for the track, and if the detection information of the short track circuit 60 or the short track circuit 61 is present, it is managed that the tram is in the check lock section 14.

  Further, when “Route 2” is configured as a route for the tram, the CPU of the ground device 50 records a non-present line as the presence line management information for the block 70 and records a presence line as the presence line management information for the block 71. If the detection information of the short track circuit 63 or the short track circuit 62 is present, the tram is managed as being present in the locked lock section 14.

  Further, when “Route 3” or “Route 4” is configured as the route for the tram, the CPU of the ground device 50 records the on-line as the on-line management information for the blocks 70 and 71, and the short track circuit 60 or When the detection information of the short track circuit 61 is present and the detection information of the short track circuit 62 or the short track circuit 63 is present, the tram is managed as being present in the locked lock section 14 To do.

When configured, it is possible to prevent a route including at least a part of the configured route from being configured as a route for a tram traveling on the other track.

  In addition, according to the present embodiment, even when there is a tram that goes straight on one track on the track 12 or 13 where there is a cesas, the operation of the tram on the other track is not hindered, and one track When changing the tram from one track to the other, it is possible to prevent the configuration of the other tram's route in the lock and lock section 14 and to run the tram in the lock and lock section 14. Can improve the safety.

  In addition, this invention is not limited to an above-described Example, Various modifications are included. For example, in FIG. 2, the trams 10 and 13 show examples of traveling in opposite directions, but the present invention can also be applied when traveling in the same direction. In this case, the management table 100 may be created in which the short track circuit on the side entering the lock and lock section 14 is a check-in track circuit and the short track circuit on the exit side is a check-out track circuit.

  In addition, in the central part of the lock lock section 14, one branch point is arranged on each of the track 12 and the track 13, and the track 12 and the track 13 are connected via one branch track.
