[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an on-vehicle signal security device in a railway security system having a deceleration control function based on a deceleration pattern, and more particularly to a railway security system for improving ride comfort and further conserving energy. And a signal security device.

[0002]

2. Description of the Related Art Recently, in the field of railways, a security system having a deceleration control function based on a deceleration pattern is often used. The railway security system referred to here is deceleration control for the train as necessary in order to prevent derailment accidents due to the train's rear-end collision and the entry of the train into the switching device during conversion during train operation. Means a system that performs

A conventional railway security system having a deceleration control function based on a deceleration pattern employs the following method. That is, first, in the on-board signal security device, based on information transmitted from the ground side (for example, a train position ahead, a track state ahead, a speed limit section ahead, or a speed limit value itself, etc.) A security deceleration pattern, which is a traveling pattern when the vehicle is decelerated as a stop target or a deceleration target in front of a train in front of the vehicle, in front of an unsatisfied path in front of the vehicle, or in front of a speed limit section, is calculated. Calculate the permissible speed for security at the train position.

Then, the permissible speed is compared with the traveling speed of the own train, and if the traveling speed of the train exceeds the permissible speed, a deceleration command is immediately output to the driving / braking device of the train. , Automatic deceleration is activated.

[0005] The security deceleration pattern calculated on the vehicle is a deceleration running pattern when a stop target or a deceleration target is set in front of a train in front of the vehicle, in front of an unsatisfied track or in front of a speed limit section, and the like. Among the deceleration targets, the position of the train ahead and the state of the path ahead change every moment, so the deceleration pattern to be recognized is switched every time information is transmitted from the ground side.

However, the above-mentioned conventional railway security system having a deceleration control function based on a deceleration pattern has the following problems. That is, deceleration operation,
Since the release is automatically performed without any notice, there is a problem that the riding comfort is poor when the vehicle is decelerated or loosened.

In a high-density operation with a short train interval, the train travels at a running speed close to an allowable speed calculated from a deceleration pattern recognized on the vehicle because the running distance between the train and the preceding train is small. As a result, the frequency of automatic deceleration by the railway security system increases, and the above-mentioned problems become more remarkable.

[0008] Further, when the frequency of automatic deceleration by the railway security system increases, the automatic deceleration is repeated or loosened, and the vehicle repeats acceleration and deceleration. As a result, useless acceleration is increased as a whole, resulting in energy saving. But not preferred.

[0009]

As described above, the conventional railway security system has a problem that riding comfort is poor and energy saving is not preferable. An object of the present invention is to provide a signal security device in a railway security system capable of improving ride comfort and further achieving an energy saving effect.

[0010]

In order to attain the above object, according to the first aspect of the present invention, a security deceleration pattern which is a traveling pattern when decelerating toward a target point is calculated. Based on the deceleration pattern calculation means and the security deceleration pattern obtained by the security deceleration pattern calculation means, calculate the permissible security speed at the current train position, and the traveling speed of the own train exceeds the permissible speed. Check if there is no running speed, and if the running speed of the own train exceeds the permissible speed, a speed checking means that outputs a deceleration command to the train driving / braking device, and a speed level higher than the security deceleration pattern An alert deceleration pattern, which is a low-speed traveling pattern, is calculated, and a traveling state surrounded by the security deceleration pattern and the alert deceleration pattern is recognized as an alert zone. Zone calculation means, and detects whether or not the running state of the train is in the alert zone recognized by the alert zone calculating means, and if the running state of the train is in the alert zone, a display device or A warning zone entry transmitting means for transmitting to the driver by a notifying means such as an alarm device.

Further, in the invention corresponding to claim 2, a security deceleration pattern calculating means for calculating a security deceleration pattern which is a traveling pattern when the vehicle decelerates toward the target point, and the security deceleration pattern calculation means is provided. Based on the security deceleration pattern, calculate the permissible speed for security at the current train position, and check whether the running speed of the own train does not exceed the permissible speed. If the permissible speed is exceeded, the speed check means that outputs a deceleration command to the train driving / braking device, and the warning deceleration pattern, which is a traveling pattern whose speed level is lower than the security deceleration pattern, are calculated, and security deceleration is performed. A warning zone calculation means for recognizing a driving state surrounded by the pattern and the warning deceleration pattern as a warning zone, and a speed checking means, It detects whether or not the running state of the car is in the alert zone recognized by the alert zone calculation means. If the running state of the train is in the alert zone, the coasting command is issued to the driving / braking device of the train. Output means.

Further, in the invention corresponding to claim 3, a security deceleration pattern calculating means for calculating a security deceleration pattern which is a traveling pattern when decelerating toward a target point, and the security deceleration pattern calculating means are provided. Based on the security deceleration pattern, calculate the permissible speed for security at the current train position, and check whether the running speed of the own train does not exceed the permissible speed. If the permissible speed is exceeded, the speed check means that outputs a deceleration command to the train driving / braking device, and the warning deceleration pattern, which is a traveling pattern whose speed level is lower than the security deceleration pattern, are calculated, and security deceleration is performed. A warning zone calculating means for recognizing a traveling state surrounded by the pattern and the warning deceleration pattern as a warning zone, and a speed checking means. When the own train and the target point are approaching, the own train is relatively controlled in the alert zone calculation means based on the relative speed between the current traveling speed of the target point and the running speed of the own train. It is determined whether or not the vehicle is approaching the alert zone recognized by, and if the own train is relatively approaching the alert zone, the drive of the own train
Means for outputting an acceleration notch suppression command to the braking device.

Further, in the invention corresponding to claim 4, a security deceleration pattern calculating means for calculating a security deceleration pattern which is a traveling pattern when the vehicle decelerates toward the target point, and the security deceleration pattern calculating means obtains the security deceleration pattern. Based on the obtained security deceleration pattern, calculate the permissible speed on security at the current train position, and check whether the traveling speed of the own train does not exceed the permissible speed,
If the traveling speed of the own train exceeds the permissible speed, the speed checking means for outputting a deceleration command to the driving / braking device of the train, and the speed checking means are provided in the own train and the target point to be targeted. When the vehicle is approaching, it is determined whether the own train is relatively approaching the security deceleration pattern based on the relative speed between the current traveling speed of the target point and the running speed of the own train. Means for outputting an acceleration notch suppression command to the drive / brake device of the own train when the own train is relatively approaching the security deceleration pattern.

Therefore, in the signal security device in the railway security system according to the first aspect of the present invention, in the warning zone calculation means, the traveling pattern on the safer side than the security deceleration pattern, that is, the speed level is lower than the security deceleration pattern. A warning deceleration pattern, which is a driving pattern, is calculated, and a driving state surrounded by a security deceleration pattern and a warning deceleration pattern is recognized as a warning zone. If the running condition of the train is in the alert zone, the running condition of the train is in the alert zone by a display device or an alarm device. To the driver.

Thus, the driver can recognize that the current train running state has approached the security deceleration pattern, and can perform a notch operation to smoothly transition from the current train running state to decelerated running. Therefore, it is possible to improve the riding comfort at the time of starting the deceleration running as compared with the related art.

According to a second aspect of the present invention, in the signal security device in the railway security system, the speed checking means detects whether or not the running state of the train is in the alert zone. If the vehicle is in the alert zone, it immediately outputs a coasting command to the driving / braking device of the train.

Thus, the coasting is always performed before the deceleration control based on the security deceleration pattern is started, so that the riding comfort at the time of starting the deceleration traveling can be improved as compared with the related art.

Further, in the signal security device in the railway security system according to the third aspect of the present invention, when the own train and the target deceleration target are close to each other in the speed check means, the target deceleration is performed. From the relative speed between the current traveling speed of the target and the traveling speed of the own train, it is determined whether or not the own train is relatively approaching the alert zone, and if the own train is relatively approaching the alert zone. In this case, an acceleration notch suppression command is immediately output to the driving / braking device of the train.

As a result, acceleration traveling is suppressed, and useless acceleration traveling is prevented, so that it is possible to improve riding comfort when decelerating traveling is started as compared with the related art. In addition, the security deceleration pattern recognized by changing the position of the train ahead and the state of the course ahead is switched, and when moving from pattern to pattern, unnecessary acceleration running near the new security deceleration pattern can be reduced, Compared with the conventional train, the distance between the train and the preceding train is particularly small, so that the riding comfort when traveling close to the security deceleration pattern is improved, and as a result, the energy saving effect can be achieved.

Further, in the signal security device in the railway security system according to the present invention, the speed check means targets the own train when the target deceleration target is approaching. From the relative speed between the current traveling speed of the deceleration target and the traveling speed of the own train, it is determined whether or not the own train is relatively approaching the security deceleration pattern. When approaching, it immediately outputs an acceleration notch suppression command to the driving / braking device of the train.

In this way, acceleration traveling is suppressed, and useless acceleration traveling is prevented, so that the security deceleration pattern to be recognized is changed due to a change in the position of the train ahead and the state of the course ahead, and when the vehicle moves from one pattern to another pattern, It is possible to reduce unnecessary acceleration running near the new security deceleration pattern, and improve the ride comfort when traveling close to the security deceleration pattern, especially with a small interval with the preceding train, compared to the past. As a result, an energy saving effect can be achieved.

Further, the security deceleration pattern calculating means 62
In consideration of the route gradient data 67, the vehicle deceleration performance data 68, and the route position data 69, the information transmitted from the ground, such as the train position ahead, the route state ahead, the speed limit section ahead, or the speed limit value, is used. Based on this, a security deceleration pattern, which is a traveling pattern in the case where the vehicle is decelerated with a stop target or a deceleration target in front of a train in front of the vehicle, in front of an unsatisfied track ahead or in a speed limit section, is calculated.

Further, the transmission / reception device 63 transmits and receives information to and from the terrestrial signal security device 54. Also,

That is, the security deceleration pattern calculating means 62
Based on the security deceleration pattern obtained by the above, the permissible speed on security at the current train position is calculated, and it is checked whether the traveling speed of the own train does not exceed the permissible speed. When the speed exceeds the permissible speed, a speed check function for immediately outputting a deceleration command to the train driving / braking device 66, and a running zone of the train to the alert zone recognized by the alert zone calculating means 61 It is detected whether or not the train is running, and if the running state of the train is in the alert zone, the train driving / braking device 66 is immediately activated.

If the own train is relatively approaching the alert zone, the train driving / braking device is determined. And a function of outputting an acceleration notch suppression command to the controller 66.

Further, the own train speed position detecting means 65
The speed and position of the own train are detected by a speed generator attached to the axle. Next, an operation of the railway security system including the on-vehicle signal security device 51 of the present embodiment configured as described above will be described.

The following information is exchanged between the ground side and the vehicle side via the ground / vehicle transmission / reception equipment 55. (A) (ground side → car side): target of deceleration of this train (B) (car side → ground side): position and running speed of this train First, in the ground signal security device 54, all the trains on the route From the train 52, the information on the status of the route opening around the station from the station interlocking device 53, and the setting information on the temporary speed limit section from the operation management system and the like.

Then, based on the received information, the target to be decelerated by each train at the present time is selected from the following deceleration targets (a) to (d).
The selected position and target speed of the deceleration target are transmitted.

(A) Among the trains on the route on which this train is going to travel, the closest preceding train (b) The unopened route ahead (c) The route is open but there is a speed limit in the route Course (d) Speed limit section other than the above (a), (b) and (c) On the other hand, the on-board signal security device 51 performs processing according to a flowchart as shown in FIG.

(Step 91) The transmission / reception device 63 receives the deceleration target (target position, target speed) selected from the ground signal security device 54.

When the target of the deceleration target is the preceding train, the traveling speed is also received. If the route is a route, the route ID and the opening status are received. (Step 903) The transmission / reception device 63 transmits the traveling speed and position of the own train obtained by the own train speed position detecting means 65 to the ground signal security device 54.

(Step 92) Next, the security deceleration pattern calculating means 62 calculates a security deceleration pattern.

Here, the security deceleration pattern is, for example, as shown in FIG.
1 (point, speed, deceleration rate) is saved as point sequence data, and each point sequence data uses the received deceleration target (target position, target speed) as an initial value and decelerates the train. The calculation is performed in the direction opposite to the traveling direction of the train, using the performance data and the running resistance value or the like based on the line gradient condition or the like.

In this case, the specific calculation processing of the security deceleration pattern is performed according to a flowchart as shown in FIG. 10, for example. Hereinafter, a specific calculation process of the security deceleration pattern will be described.

(Step 1001) Initial values are set. The received deceleration target (target position, target speed) is set to the initial value of the security deceleration pattern.

Here, if the received deceleration target is a course, the course ID and the status of its establishment are transmitted, so that the car has the course data (path ID, course position [km]) as the course data. The deceleration target position is recognized with reference to this.

(Step 1002) The counter is set. (Step 1003) As security deceleration pattern data,
Save the calculated (position, speed, deceleration rate). However,
In the first loop, only the initial values (target position, target speed) are stored.

(Step 1004) The running resistance R and the deceleration F are calculated. For these calculations, it is conceivable that the parameters required for the model calculation are previously provided on the vehicle as a database and are referred to.

Here, the parameters held as the database include, for the model calculation of the running resistance force, the road gradient data (point sequence data of the position [m] and the gradient value [0/00]), and the model of the deceleration force. The calculation includes deceleration performance data (point sequence data of speed level [km / h] and deceleration force [N]) of the own train.

(Step 1005) Step 100
The deceleration α is calculated using the running resistance R and the deceleration F obtained in Step 4 and the weight M of the own train.

In this case, the running resistance R and the deceleration force F are obtained by a model calculation. However, in order to simplify the calculation, a method of preparing the deceleration data as an on-vehicle database in advance and referencing the data is also considered. Can be

In this case, the deceleration greatly differs depending on the gradient of the route, and it is conceivable that the deviation from the actual deceleration running pattern becomes large. It is preferable to adopt a method such as switching at a position where the gradient is steep.

(Step 1006) The speed V is calculated. In this case, the calculation is performed using the equation in step 1006 in FIG.

(Step 1007) The position P is calculated. In this case, the calculation is performed using the equation in step 1007 in FIG.

(Step 1008) Step 100
When the value of the position P calculated in step 7 reaches the maximum speed of this line section, the security deceleration pattern calculation ends.

(Step 93) Next, the guard deceleration zone calculating means 61 calculates the guard deceleration pattern and recognizes the guard zone.

Here, the calculation of the alert deceleration pattern will be described with reference to FIGS. 7 and 8 are conceptual diagrams illustrating the relationship between the security deceleration pattern and the alert deceleration pattern.

The security deceleration pattern is a traveling pattern in which the vehicle is decelerated as a stop target or a deceleration target in front of a train in front of the vehicle, in front of an unsatisfied track ahead or in front of a speed limit section.

The alert deceleration pattern is a pattern for recognizing that the traveling state of the train, that is, detecting that the speed and the position are approaching the security deceleration pattern, is, for example, the alert deceleration shown in FIG. The speed of the security deceleration pattern, such as the pattern calculated using the deceleration force performance of the train adopted in the security deceleration pattern or the value of 10% reduction of the deceleration rate, or the alert deceleration pattern shown in FIG. A pattern in which the level is simply set to a level lower by 5 [km / h] can be considered.

Here, in the former case, the calculation may be performed in the same manner as the method of calculating the security deceleration pattern. In the latter case, for example, 5 km / km from the security deceleration pattern
h] may be subtracted.

The alert zone is recognized as a hatched portion between the security deceleration pattern and the alert deceleration pattern shown in FIGS. That is, the traveling state of the alert zone is lower than the security deceleration pattern and has a higher speed level than the alert deceleration pattern.

(Step 94) Next, the speed and position of the own train obtained by the own train speed position detecting means 65 are compared with the security deceleration pattern obtained in Step 92 and the alert zone obtained in Step 93. Cases are divided into three cases.

Here, the contents of the case are as shown in step 902 in FIG. 9. For each of case 1 to case 3, the processing of step 95 to step 97 described later is performed.

The processing after step 94 is performed by the speed checking means 64. (Step 95) This process is performed when the speed level of the train is higher than the security deceleration pattern in step 94, and immediately outputs a deceleration command to the drive braking device 66 of the train.

(Step 96) In step 94,
This processing is performed when the speed level of the train is lower than the security deceleration pattern and higher than the alert deceleration pattern, that is, when the running state is in the alert zone, and the coasting command is issued to the train driving / braking device 66. Is output.

Thereafter, the processing of steps 97 to 901 is performed when the speed level of the train is lower than the warning deceleration pattern in step 94. (Step 97) The distance L between the target deceleration target position and the position of the own train is calculated.

(Step 98) A case where the distance L obtained in step 97 is small and a case where it is large are classified. Here, for the determination of large or small, a certain threshold value is set in advance, and whether it is larger or smaller is distinguished.

As a result, if the distance L is small,
In order to prevent the running state of the own train from immediately entering the alert zone, and thereby resulting in unnecessary acceleration running, the processing after step 99 is performed.

On the other hand, when the distance L is large, it is determined that the traveling state of the own train will not immediately enter the alert zone, and no command is output to the drive / brake device 66 of the train.

That is, the driver performs the notch operation with the target of the reference speed in this section as a target, and is instructed to the drive braking device 66 of the train. (Step 99) The relative speed V 'between the deceleration target and the own train is calculated.

Here, when the target of the deceleration target is the preceding train, the difference between the traveling speed and the traveling speed of the own train is calculated, and the target of the deceleration target is a route other than the preceding train or a speed-limited section. For example, the running speed value of the own train is used.

(Step 901) The case is classified depending on whether the relative speed between the deceleration target obtained in step 99 and the traveling speed of the own train is positive or negative.

If the relative speed is negative (including zero), the deceleration target and the own train are relatively far apart or the same distance is maintained. On the other hand, the alert zone is moving away or moving at the same speed. In this case, it is determined that the own train will not enter the alert zone for the time being, and the train drive braking device 66 Do nothing.

On the other hand, if the relative speed is positive, the process of step 902 is performed. (Step 902) This processing is performed when the relative speed obtained in Step 99 is positive.

In this case, since the deceleration target and the own train are relatively approaching, the alert zone is approaching the own train. Is determined to be likely to enter the alert zone immediately, a command to suppress the acceleration notch is output to the driving / braking device 66 of the train so as not to output an acceleration force exceeding a certain level.

Here, the command for suppressing the acceleration notch means that when the acceleration force is controlled at several levels called a notch, an operation at a certain notch stage or higher is performed so as not to output an acceleration force higher than a certain level. Means to ban.

As described above, in the railway security system provided with the on-board signal security device 51 of the present embodiment, the speed checking means 64 determines whether the running state of the train is in the alert zone or not. When the detection is made and the running state of the train is in the alert zone, the function of immediately outputting the coasting command to the driving / braking device 66 of the train, and the own train and the target deceleration target approach each other, If you have
From the relative speed between the current moving speed of the target deceleration target and the running speed of the own train, it is determined whether the own train is relatively approaching the warning zone or not, and if it is approaching the warning zone Is a train driving / braking device 6
6, a function of outputting an acceleration notch suppression command is added.

Therefore, since the coasting is always performed before the deceleration control based on the security deceleration pattern is started, it is possible to improve the riding comfort when starting the deceleration traveling as compared with the conventional case described above. Become.

Further, since the acceleration traveling is suppressed and the useless acceleration traveling is prevented, it is possible to improve the riding comfort when starting the deceleration traveling as compared with the conventional case described above. Instead, the security deceleration pattern recognized by changing the position of the train ahead and the course condition ahead is switched, and when moving from pattern to pattern, it is possible to reduce unnecessary acceleration traveling near the new security deceleration pattern, Compared to the conventional case described above, especially when the distance from the preceding train is small, the ride comfort when traveling close to the security deceleration pattern is improved, and unnecessary acceleration traveling is reduced, and energy saving effect can be achieved. It becomes possible.

(Second Embodiment: Corresponding to Claim 1) In this embodiment, the overall configuration and the on-board configuration in the above-described first embodiment are the same, and the configuration is changed only in the following points. .

That is, the on-vehicle signal security device 51 is
As shown in the basic configuration example in FIG.
Based on the security deceleration pattern, calculate the permissible speed for security at the current train position, and check whether the running speed of the own train does not exceed this permissible speed. If the speed is exceeded, a function of immediately outputting a deceleration command to the driving / braking device 66 of the train, that is, a function equivalent to the speed checking function of the conventional on-board signal security device 51, is used. A zone entry transmission device 70 is added.

Here, the warning zone entry transmission device 70
It is detected whether or not the running condition of the train is in the alert zone recognized by the alert zone calculating means 61. If the running condition is included, the running condition of the train is alerted by a notification device such as a display device or an alarm device. It informs the driver that he is in the zone.

In the railway security system provided with the on-vehicle signal security device 51 of the present embodiment configured as described above,
The alert zone calculating means 61 calculates a traveling pattern on the safer side than the security deceleration pattern, that is, an alert deceleration pattern that is a traveling pattern having a lower speed level than the security deceleration pattern, and is surrounded by the security deceleration pattern and the alert deceleration pattern. The running zone is recognized as the alert zone, and the alert zone entry transmitting device 70 detects whether or not the running zone of the train is in the alert zone recognized by the alert zone calculating means 61, and Is in the alert zone, the driver is informed that the running state of the train is in the alert zone by notification means such as a display device or an alarm device.

Therefore, the driver can recognize that the current driving state has approached the security deceleration pattern, and can perform the notch operation to smoothly transition from the current driving state to the deceleration driving. It is possible to improve the riding comfort at the time of starting the deceleration running, as compared with the case of.

(Third Embodiment: Corresponding to Claim 2) In this embodiment, the overall configuration and the on-board configuration in the first embodiment are the same, and only the following points are changed. .

That is, the on-board signal security device 51 is
As shown in the basic configuration example in FIG.
The running speed of the preceding train is not taken into account, and the security deceleration pattern obtained by the security deceleration pattern calculating means 62, the alert zone obtained by the alert zone calculating means 61, and the speed measured by the own train speed position detecting means 65 are measured. Based on the position and speed of the own train,
6, a deceleration command or coasting command is output.

In other words, the above-mentioned original speed checking function detects whether or not the running state of the train is in the alert zone recognized by the alert zone calculating means, and determines whether the running state of the train is in the alert zone. In this case, a function of immediately outputting a coasting command to the train driving / braking device 66 is added.

In the railway security system provided with the on-board signal security device 51 of the present embodiment configured as described above,
The speed checking means 64 detects whether or not the running state of the train is in the alert zone. If the running state of the train is in the alert zone, the train driving / braking device 66 is immediately actuated. A coasting command is output.

Therefore, since the coasting is always performed before the deceleration control based on the security deceleration pattern is started, it is possible to improve the riding comfort when starting the deceleration traveling as compared with the conventional case described above. Become.

(Fourth Embodiment: Corresponding to Claim 4) In this embodiment, the configuration is the same as the overall configuration and the on-board configuration in the first embodiment described above, and the configuration is changed only in the following points. .

That is, the on-vehicle signal security device 51 is
As shown in the basic configuration example, the warning zone calculating means 61 is omitted, and instead, the speed checking means 64 is
In consideration of the traveling speed of the preceding train received by the transmitting / receiving device 63, the security deceleration pattern obtained by the security deceleration pattern calculation means 62 and the position and speed of the own train measured by the own train speed position detection means 65 On the basis of this, a deceleration command or an acceleration notch suppression command is output to the train driving / braking device 66.

In other words, when the own train and the target deceleration target are approaching the above-described original speed check function, the current moving speed of the target deceleration target and the traveling speed of the own train are used. From the relative speed with respect to, it is determined whether or not the own train is relatively approaching the security deceleration pattern, and if the own train is relatively approaching the security deceleration pattern, the train driving / braking device 66 The function to output the acceleration notch suppression command has been added.

In the railway security system provided with the on-vehicle signal security device 51 of the present embodiment configured as described above,
By the speed checking means 64, when the own train and the target deceleration target are approaching, from the relative speed between the current moving speed of the target deceleration target and the traveling speed of the own train,
It is determined whether or not the own train is relatively approaching the security deceleration pattern. If the own train is relatively approaching the security deceleration pattern, the acceleration notch suppression is performed on the driving / braking device 66 of the train. Command is output.

Therefore, since the acceleration traveling is suppressed and useless acceleration traveling is prevented, the security deceleration pattern to be recognized is changed due to a change in the position of the train ahead and the state of the course ahead, and when the vehicle moves from one pattern to another pattern, Since the useless acceleration traveling near the new security deceleration pattern can be reduced, the ride comfort when traveling close to the security deceleration pattern is particularly small compared to the previous case described above, especially with a small distance from the preceding train.
