Abstract

PROBLEM TO BE SOLVED: To allow a ground device to transmit temporary speed set information in which temporary speed set section suitable for each train is calculated in a track section including a branching point and a merging point.SOLUTION: The train control system determines how far the temporary speed information is prepared for a train travel track, prepares the temporary speed set information to the track section advancing port when the train travels on the temporary speed set track on and after a junction, and prepares the temporary speed set information to the junction when the train travels on the track in which temporary speed is not set on and after the junction. A data transmitting/receiving part 13 of the ground device 10 transmit the prepared temporary speed set information to an on-board device 20 through a transmission means 16. The on-board device which has received the temporary speed set information controls the train so that the train travels at a speed below the speed limit.

Description

  The present invention relates to a train control system and a train control method, and more particularly to a temporary speed limit system and a temporary speed limit train operation method for temporarily limiting a train speed.

  Temporary speed limit (hereinafter referred to as "temporary speed") is a temporary speed limit during railway operation. In addition to the normal maximum speed, measures against concentrated heavy rain and strong winds, or construction / track maintenance work It is a speed limit that is temporarily set in the target section at times.

  At present, the general speed setting method is, as in Patent Document 1 (Japanese Patent Application Laid-Open No. 2004-359020), a track speed unit obtained by dividing the speed setting section and the speed limit into a predetermined section. The train travels below the speed limit specified in the track section where the critical speed is set.

  However, in this method, since the range for setting the critical speed setting section is for each track section, even if it is necessary to set the critical speed for only a part of the track section, the train Will run below the speed limit.

  As an improvement measure, as in Patent Document 2 (Japanese Patent Application Laid-Open No. 2007-99040), the starting point and the ending point of the super-speed setting section are transmitted to the train as distance information from the entrance of the track section, regardless of the track section. There is a way to set it freely.

  However, in the track section, there is a track section with branching / merging. In a track section having such branching / merging, there are a plurality of routes having the same distance from the entrance of the track section. For this reason, the train cannot distinguish between the section where the critical speed is set and the section where the critical speed is not set only by the distance information from the entrance of the track section, even in the section where the critical speed is not set. In the section where the critical speed is set and the section where the distance from the entrance of the track section is the same, the vehicle travels below the speed limit. As a result, at the terminal station where the number of branches and merges is large, the operation efficiency is affected.

JP 2004-359020 A JP 2007-99040 A

  The problem to be solved by the present invention is that when the critical speed is set in the track section with branching / merging, the train is set only in the distance information from the entrance of the track section. In the course where the distance from the entrance of the orbital section is the same as the section where the critical speed is set, even in the section where the critical speed is not set, the section where the critical speed is not set can not be distinguished It travels below the speed limit and affects the operation efficiency.

  Therefore, the present invention is based on the difference between the route direction in which the train travels and the ground device has a branch in the track direction and the track direction in order to appropriately create the quick setting information to be set in the target train. -The most important feature is that the position of the merge is retained as distance information.

The speed information is generated and transmitted to the on-board device of the train via the data transmission / reception unit.

  Hereinafter, an embodiment of the present invention will be described with reference to the drawings. An embodiment of a train control system according to the present invention is shown in FIG. This system is a train control system that has an on-board device and a ground device and controls a train.

  The train 1 carries the on-board device 20 and travels on a track range in which the ground device 10 holds route data in the data storage unit 11.

Table 1 is an example of the data storage unit 11 and shows the track section length, the presence / absence of branch / junction in the track section, and the distance from the entrance to the branch / join. An example of the track shown in FIG. 2 is as shown in Table 1 below.

  The on-board device 20 creates train position information and transmits the train position information to the calculation unit 12 via the transmission means 16 and the data transmission / reception unit 13. The transmission means 16 transmits and receives information between the data transmitting / receiving unit 13 and the on-board device 20. In addition, an interlocking device 15 is connected to the ground device 10. The interlocking device 15 transmits the route opening information to the calculation unit 12.

  The calculation unit 12 creates train control information for each train traveling based on the train position information received from the onboard device 20 and the route opening information received from the interlocking device 15, and is transmitted to the data transmission / reception unit 13. The information is transmitted to the on-board device 20 via the means 16.

  The on-board device 20 creates a brake pattern based on the received train control information and controls the train 1 or 2.

  A ground speed device 14 is connected to the ground device 10. The critical speed device 14 sets, in the ground device 10, a section where the critical speed is set, a position where the critical speed starts and a position where the critical speed ends based on distance information from the orbital section 1T entrance.

  When the critical speed is set by the critical speed device 14, the ground device 10 causes the calculation unit 12 to set the critical speed setting section information for each orbital section (presence / absence of the critical speed for each orbital section, the orbital section where the critical speed starts, The distance from the position where the critical speed starts to the exit of the track section where the critical speed starts, the track section where the critical speed ends, the entrance of the track section where the critical speed ends and the position where the critical speed ends Create a distance).

Table 2 shows the calculation unit according to the embodiment of the present invention when the critical speed device 14 sets the critical speed setting section from the 1T to 900 m position and ends in the A direction from 1T to 1600 m. 12 shows an example of quick setting section information created by Twelve.

  This temporary speed setting section information is held in the data storage unit 11. The critical speed device 14 sets the critical speed not the distance information from the 1T entrance, but the critical speed setting section information for each track section in Table 2 (presence / absence of critical speed for each track section, and the critical speed starts. The track speed ends from the track section, the distance from the position where the critical speed starts to the exit of the track section where the critical speed starts, the track section where the critical speed ends, and the entrance of the track section where the critical speed ends. The distance to the position may be set. In this case, the calculation unit 12 does not create the immediate speed setting section information, but only stores it in the data storage unit 11.

  On the ground device 10, the on-board device 20 of the train traveling in the fast-setting section is based on the quick-speed setting section information, the train position information received from the on-board device 20, and the route opening information received from the interlock device 15. On the other hand, the train control information to which the quick setting information is added is transmitted.

  In the embodiment of the present invention, the calculation unit 12 determines which route the train travels from the route opening information received from the interlocking device 15, and creates quick speed setting information corresponding to the travel route. For example, when the track is branched in the A direction and the B direction in the middle of the section 3T, and the train 1 travels in the A direction, the calculation unit 12 can obtain the critical speed from the critical speed start point to the critical speed end point. Setting information is created and transmitted to the on-board device 20 via the data transmitter / receiver 13 and the transmission means 16.

  As an example, it is assumed that the critical speed is set in the section indicated by the thick line in FIG. In the conventional super-speed setting, both the train 1 traveling in the A direction and the train 2 traveling in the B direction are set as “sections ending from 1T to 1600 m”. Is as shown in FIG. In this case, for the train 2 traveling in the B direction, an extra speed setting is set.

  In such a case, in the embodiment of the present invention, for the train 1 traveling in the A direction from the 1T section to the 4T section, it enters the 2T and 3T sections from the 1T section and branches in the middle of the 3T section. Thus, the super-speed setting information is different for the train 2 traveling in the B direction of the 5T section. That is, for example, in the super-speed setting information transmitted to the on-board device of the train 1 traveling in the A direction, the super-speed setting section length is [distance (100 m) between the 2T super-speed start point and the track section exit / exit]. And [3T track section length (500 m)] and [4T track section entry / exit distance (100 m)] are 700 m. In the case of the train 2 traveling in the B direction, the calculation unit 12 creates the emergency speed setting information from the emergency speed start point to the branch / merge point, and the data transmission / reception part 13 and the transmission means 16 It transmits to the on-vehicle device 20.

  In the above-mentioned specific example as an example, the super-speed setting section length of the super-speed setting information transmitted to the on-board device of the train 2 traveling in the B direction is [distance between the 2T super-speed start point and the track section exit / exit. (100 m)] and [distance from 3T entrance to branch point (80 m)] are added to give 180 m.

  In summary, the train control system includes the ground device 10, the on-board device 20, the immediate speed device 14, and the interlocking device 15. In such a train control system, the ground device 10 retains the temporary speed setting section information when the temporary speed device 14 sets a temporary speed setting section for temporarily running the train below the speed limit. A data storage unit 11 is provided. The data storage unit 11 stores in advance the presence / absence of branching / merging of the track section, the distance from the track section entry / exit to the branch point, and the distance from the join point to the track section exit / exit. The calculation unit 12 determines how far the preliminary speed information is created based on the route on which the train travels. After the fork, when the train travels in the section where the speed is set, create the speed setting information up to the track section exit and exit, and after the fork, the train travels in the section where the speed is not set If so, the quick setting information up to the branch point is created. Similarly, when the train travels in the section where the speed is set before the junction, create the speed setting information from the entrance to the track section, and the train is not set at the speed before the junction. When traveling in a section, the super speed setting information from the junction is created. The data transmission / reception unit 13 of the ground device 10 transmits the created immediate speed setting information to the on-vehicle device 20 via the transmission means 16.

  Then, the on-board device that has received the preliminary speed setting information controls the train so that it travels below the speed limit.

  In this way, according to the present embodiment, when the critical speed is set in the track section with branching / merging, only the critical speed setting section in which the train travels for the train traveling on the route that is not set. Only the preliminary speed information is transmitted, and the train can travel at a normal speed on a route that is not set.
