Description

  The present invention relates to a train control system including a ground device and an on-board device.

  A digital ATC, which is a type of train control system, employs a pattern control system that creates and uses a speed check pattern that ends at the final point (stop position) where a train is allowed to enter. In the method for creating the speed check pattern, first, the ground device transmits information such as the train position and stop position to the rail. In addition to the information received from the rail by the on-board device, the speed check pattern is determined based on the track conditions such as the predetermined track gradient and radius of curvature, and the specifications of the train (brake performance, vehicle weight, etc.). Generate.

  However, in this method, the on-board device needs to include an on-board DB that stores the track conditions in advance. For this reason, when there is a change in track conditions for a section of the travel line section such as a linear change or mutual direct operation, the on-board devices of all trains that may travel in the travel line section It was necessary to update the DB and verify that there was no hindrance to the running of each train for each train. This problem was particularly noticeable in metropolitan areas where many trains exist.

  On the other hand, a technique of a pattern control method that does not need to store track conditions in the on-board DB has also been proposed (Patent Document 1). In this system, the ground device has a ground DB that stores the track conditions, and based on the on-line position of each train, the speed control table is generated by referring to the track conditions stored in the ground DB and the rails. Send to. The on-board device creates a speed control pattern according to the speed control table received via the rail. The speed control table includes the allowable start end speed when entering the track circuit to which the table is transmitted, the allowable travel section length at the start allowable speed, the allowable end speed, the allowable deceleration section length for deceleration, and the like. Yes. According to this method, when the track condition is changed, only the ground DB needs to be updated.

Japanese Patent No. 4551554

[overall structure]
FIG. 1 is a schematic configuration diagram of a train control system 1 in the present embodiment. The train control system 1 includes a ground device 10 and an on-board device 30 mounted on a train 20 that travels on a rail R. In the rail R, a section serving as a unit of train control in which the rail R is divided along the traveling direction of the train 20 is defined. This section is determined in units of track circuits installed along the rail R.

  The ground device 10 includes a plurality of transmitters 12 and a ground control device 14. The transmitter 12 is installed at or just before the boundary on the advancing side of each section, and transmits the traveling control information 40 generated by the ground control device 14 to the rails of the connected section. The ground control device 14 determines each train on the track based on information on the position of each train detected in track circuit units (ie, section units) (track information), route information obtained from a not-shown interlocking device, and the like. The travel control information 40 for the train 20 is generated and repeatedly transmitted via the transmitter 12 to the rails of the corresponding train section of the train 20.

  The on-board device 30 performs speed control of the own train based on the traveling control information 40 received from the rail.

The travel control information 40 includes a section ID (ID ₀ ) and a terminal allowable speed V _e0 that are information on a section (the section) in which the information is transmitted, and a section ID (ID ₁ ) that is information on an adjacent inner section. , The start end allowable speed V _s1 and the start end allowable speed length L _n 1. Here, the subscript “0” indicates that the information is transmitted in the section, and the subscript “1” indicates that the information is in the adjacent inner section. The section ID corresponds to section identification information for identifying a section. The start end allowable speed V _s is a speed limit at the entry side end of the corresponding section, and the end allowable speed V _e is a speed limit at the advance side end of the corresponding section. The start end allowable speed V _s and the end allowable speed V _e are determined according to the position of the preceding train (the existing section). Start permissible speed length L _n is the length to continue the start permissible speed V _s from the entrance end of the relevant section (range).

[Train control method]
Train control based on the travel control information 40 will be described. In the present embodiment, the on-board device 30 calculates and determines the verification speed V _x corresponding to the current travel position L _x of the own train based on the travel control information 40 received from the rail, so to speak. . Then, the speed control of the train by comparing the Shosa velocity V _x and the current speed V.

As shown in FIG. 2, the on-board device 30 determines from the received travel control information 40 that the start allowable speed V _s0 , the start allowable speed length L _n0 and the allowable end speed V _e0 related to the current section of the own train 20, and the next section The start end allowable speed V _s1 and the start end allowable speed length L _n1 are obtained. The running position L _x of the train is the distance from the entrance end of the rail section. Specifically, the on-board device 30 calculates the travel distance from time to time based on the measured value of the rotational speed of the speed generator attached to the axle, and enters a new zone based on the received travel control information 40. If it is determined, the calculated travel distance is reset. This travel distance and the travel position L _x.

First, when the start end allowable speed V _s0 of the existing section is equal to or lower than the start end allowable speed V _s1 of the next section (V _so ≦ V _s1 ), the verification speed V _x is set at any travel position L _x in the existing section. Is also set to the start end allowable speed V _s0 of the existing line section. If the verification speed V _x for each of the travel positions L _x is calculated and created as a speed control pattern, the result is as shown in FIG.

Next, when the start end allowable speed V _s0 of the current section exceeds the start end allowable speed V _s1 of the next section (V _s0 > V _s1 ), the verification speed V _x is calculated and determined separately in two cases.

In other words, if the train position L _x is within the range of the start end allowable speed length L _n0 of the existing line section (L _x ≦ L _n0 ), the start end allowable speed V _s0 of the existing line section is set as the verification speed V _x .

この式（１）は、在線区間の始端許容速度Ｖ_ｓ０から次区間の始端許容速度Ｖ_ｓ１まで、所定の減速度βで減速した場合の任意の地点Ｌ_ｘの照査速度を求める演算式である。始端許容速度長Ｌ_ｎ０の位置が、在線区間における減速（ブレーキ）の開始位置となる。減速度「β」は、列車の通常ブレーキでの最大減速度を、対象線区（当該列車が走行する線区）内の最急上り勾配（例えば、４０‰）で補正して定められ、４〜６［ｋｍ／ｈ／ｓ］程度の定数である。また、「Ｔ_０」は、空走時間であり、２〜３秒程度の定数である。 On the other hand, if the train position _{L x} is outside the range of the starting allowable speed length _{L n (L x> L n0} ), in accordance with the following equation (1) to calculate the Shosa velocity _{V x} at train position _{L x.}

This expression (1) is an arithmetic expression for obtaining a verification speed at an arbitrary point L _{x when} the vehicle is decelerated at a predetermined deceleration β from the start end allowable speed V _s0 of the current section to the start end allowable speed V _s1 of the next section. . The position of the start end allowable speed length L _n0 is the start position of deceleration (brake) in the existing line section. The deceleration “β” is determined by correcting the maximum deceleration in the normal brake of the train with the steepest ascending slope (for example, 40 ‰) in the target line (the line where the train travels). It is a constant of about ~ 6 [km / h / s]. Further, “T ₀ ” is an idle running time and is a constant of about 2 to 3 seconds.

Further, the speed V _x calculated by the expression (1) is not unconditionally set as the verification speed V _x , but if the calculated speed V _x is equal to or higher than the terminal allowable speed V _{e0 in the} current line section (V _x ≧ V _e0 ). , the calculated velocity _{V x} and Shosa speed _{V x,} the calculated velocity _{V x} is if termination permissible speed _V less than _{e0 (V} x _{<V e0),} the terminal velocity _{V e0} of rail sections and Shosa velocity _{V x.}

The following describes setting start permissible speed length L _n that is included in the travel control information. First, a braking distance L ₀ required to decelerate at a predetermined deceleration β ₀ such as the maximum deceleration at the normal brake of the train from the start end allowable speed V _s to the end allowable speed V _{e of} the target section is calculated. Then the section length L of the target section, and the braking distance L _0, the distance obtained by subtracting the predetermined safety margin distance L _a, a distance obtained by multiplying a predetermined coefficient k (0 <k <1) , the start of the subject section the permissible speed length _{L n.}

Note that the deceleration β ₀ and the coefficient k may be different depending on the distance measurement error. The distance measurement error is an error that occurs when the traveling position (train position L _x ) is measured using the measurement value of the speed generator in the on-board device 30, and is mainly caused by the idling or running of the train. As the distance measurement error is larger, the coefficient k is increased and the deceleration β ₀ is increased, so that the operation on the safe side is performed.

As described above, the verification speed V _x corresponding to the train position L _x is calculated and determined in a so-called pinpoint manner. When the start end allowable speed V _s0 of the current section exceeds the start end allowable speed V _s1 of the next section (V _s0 > V _s1 ), the verification speed V _{x of} each travel position L _x is calculated according to the calculation method described above. If it is created as a speed control pattern, it is as shown in FIG. FIGS. 3 and 4 show a case where a speed control pattern is temporarily created. In this embodiment, train control can be performed without creating such a speed control pattern.

[Function configuration]
FIG. 5 is a functional configuration diagram of the on-board device 30. The on-board device 30 is a computer device that includes the processing unit 100 and the storage unit 200.

  The processing unit 100 is realized by an arithmetic device such as a CPU, for example, and performs overall control of the on-board device based on programs, data, and the like stored in the storage unit 200. In addition, the processing unit 100 includes a position / velocity calculation unit 102, a section entry determination unit 104, an information change determination unit 106, a section information update unit 108, a verification speed determination unit 110, and a speed control unit 112. Then, a train control process (see FIG. 6) according to the train control program 202 is executed.

The position speed calculation unit 102 calculates the current travel position L _x of the own train and the travel speed based on the measured value of the rotational speed of the speed generator attached to the axle. In addition, when the entry to the next section is determined by the section entry determination unit 104, the traveling position _Lx is reset. In other words, the travel position L _x is calculated as the travel distance from the entry side end of the existing line section. The calculated travel position L _x is stored as travel position data 204, and the travel speed is stored as travel speed data 206.

  The section entry determination unit 104 determines entry of the own train into a new section (next section) based on a change in the section ID included in the received travel control information 40.

The information change determination unit 106 determines a change in the travel control information 40 although the on-line section of the own train has not changed. Since the start allowable speed V _s and the end allowable speed V _e of each section are determined according to the position of the preceding train, if the position of the preceding train is changed, the start allowable speed of the current section and the inward section of the own train is changed. V _s and the end permissible speed _{V e} changes. The information change determination unit 106 determines a change in the content of the travel control information 40 that accompanies the change in the existing section of the preceding train. That is, although the section ID and the inner section ID included in the received travel control information 40 are not changed, the end allowable speed V _{e0 of} the section, the start allowable speed V _{s1 of} the inner section, the inner When the start end allowable speed length L _{n1 of the} section changes, it is determined that the traveling control information 40 has changed.

The section information update unit 108 stores the stored line section information 214 based on the received travel control information 40 when the section entry determination unit determines entry into a new section (next section), and Next section information 216 is updated. The standing section information 214 includes a section ID (ID _a ) of the standing section, a start end allowable speed V _sa , a terminal end allowable speed V _ea , and a start end allowable speed length L _na . The next section information 216 includes the section ID (ID _b ) of the next section, the start end allowable speed V _sb, and the start end allowable speed length L _nb . The subscript “a” indicates information on the existing section, and “b” indicates information on the inner section adjacent to the existing section.

That is, the section ID (ID _b ), the start end allowable speed V _sb , and the start end allowable speed length L _nb of the next section information 216 are set to the section ID (ID _a ), the start end allowable speed V _sa , and and the beginning permissible speed length _{L na.} Further, the terminal allowable speed V _e0 of the section included in the travel control information 40 received by entering the new section is set as the terminal allowable speed V _ea of the existing line section information 214 and included in the travel control information 40. The section ID (ID ₁ ), the start end allowable speed V _s1 , and the start end allowable speed length L _n1 of the inner section, the section ID (ID _b ), the start end allowable speed V _sb , and the start end allowable speed of the next section information 216 are used. The length is L _nb .

Further, when the change of the travel control information 40 is determined by the information change determination unit 106, the stored in-zone section information 214 and the next section information 216 are updated based on the received travel control information 40. . That is, the terminal allowable speed V _e0 of the section included in the received travel control information 40 is set as the terminal allowable speed V _ea of the existing section information 214 and the start allowable speed V of the inner section included in the travel control information 40. Let _s1 and the start end allowable speed length L _n1 be the start end allowable speed V _sb and the start end allowable speed length L _nb of the next section information 216.

The verification speed determination unit 110 determines the verification speed V _x at the current travel position L _x of the own train. That is, when the start end allowable speed V _sa of the current section is equal to or lower than the start end allowable speed V _sb of the next section (V _sa ≦ V _sb ), the start end allowable speed V _sa of the current section is set as the verification speed V _x . In addition, when the start end allowable speed V _sa of the current section exceeds the start end allowable speed V _sb of the next section (V _sa > V _sb ), the verification speed V _x is determined according to the traveling position L _x of the own train. . That is, if the travel position L _x does not reach the start end speed allowable length L _na of the existing line section (L _x ≦ L _na ), the start end allowable speed V _sa of the existing line section is set as the verification speed V _x. position _{L x} is if has reached the start permissible speed length _{L na} of rail section _{(L x> L na),} from equation (1), and calculates the velocity _{V x} corresponding to the running position _{L x.} If the calculated speed V _x is equal to or higher than the terminal end allowable speed V _ea of the current line section (V _x ≦ V _ea ), the calculated speed V _x is set as the verification speed V _x , and the calculated speed V _x is the terminal end allowable speed of the current line section. If it is less than the speed V _ea (V _x <V _ea ), the termination allowable speed V _ea in the current section is set as the verification speed V _x .

Here, the calculation formula (1) of the verification speed V _x is stored as the verification speed calculation formula data 210, and the deceleration β and constant idle time T ₀ in the formula (1) It is stored as a speed calculation parameter 212. The check speed calculation parameter 212 is appropriately determined according to the specifications of the own train, the maximum gradient of the travel line section, and the like. Further, the determined verification speed V _x is stored as verification speed data 208.

The speed control unit 112 performs speed control based on the verification speed V _x calculated by the verification speed determination unit 110. That is, the verification speed V _x is compared with the current travel speed calculated by the position speed calculation unit 102. When the travel speed exceeds the verification speed V _x , the brake is operated to decelerate to the verification speed V _x. Let

  The storage unit 200 is realized by a storage device such as a ROM, a RAM, and a hard disk, for example, and stores a program, data, and the like for the processing unit 100 to control the on-board device 30 in an integrated manner. Used as a work area, the calculation result executed by the processing unit 100 is temporarily stored. In the present embodiment, the storage unit 200 includes a train control program 202, travel position data 204, travel speed data 206, verification speed data 208, verification speed calculation formula data 210, and verification speed calculation parameters 212. In-line section information 214 and next section information 216 are stored.

[Process flow]
FIG. 6 is a flowchart for explaining the flow of the train control process. According to FIG. 6, first, the section entry determination unit 104 determines entry into a new section (next section) based on the section ID included in the received travel control information 40 (step S1). . If it is determined that the vehicle has entered the next section (step S1: YES), the section information update unit 108 updates the existing section information 214 and the next section information 216 based on the received travel control information 40. (Step S3). The position speed calculation unit 102 resets the running position _{L x} (step S5).

  On the other hand, if entry into the next section is not determined (step S1: NO), the information change determination unit 106 determines a change in the received travel control information 40 (step S7). If it is determined that the travel control information 40 has changed (step S7: YES), the section information update unit 108 updates the existing section information 214 and the next section information 216 based on the received travel control information 40. (Step S9).

Subsequently, the verification speed determination unit 110 determines the verification speed V _x at the current travel position L _x . That is, if the start end allowable speed V _sa of the current line section is equal to or lower than the start end allowable speed V _sb of the next section (step S11: YES), the start end allowable speed V _sa of the current line section is set as the verification speed V _x (step S13). .

On the other hand, starting allowable speed _{V sa} of rail section is if more than starting allowable speed _{V sb} follows interval (step S11: NO), the traveling position _{L x} is either within the range of starting allowable speed length _{L na} of rail section Determine if out of range.

If the start end allowable speed V _sa of the current section is outside the range of the start end allowable speed V _sb of the next section (step S15: NO), the verification speed V _x corresponding to the travel position L _x is calculated using equation (1). Calculate (step S19). Next, if the calculated verification speed V _x is less than the terminal allowable speed V _ea of the current section (step S21: YES), the terminal allowable speed V _ea is set as the verification speed V _x (step S23).

Upon determining the Shosa speed V _x, the speed control unit 112 performs speed control by comparing the Shosa speed and travel speed (step S25). Then, it returns to step S1 and repeats the same process.
