Description
Technical Field
The invention relates to the technical field of railway transportation, in particular to a method and a device for determining train movement authorized distance.
Background
An ATP (Automatic Train Protection) system is a key device for ensuring safe operation of a Train. The train is continuously transmitted with movement authorization through ATP ground equipment arranged beside a track so as to ensure the safe separation distance between a subsequent train and a previous train. The safety separation distance can ensure the safety between the preceding train and the adjacent subsequent train. And each train periodically reports the position to the ATP system, so that the ATP system can accurately acquire the real-time position of each train and transmit the movement authorization for each train.
Because the safe separation distance exists between the trains, even if a certain train moves backwards due to an emergency, the preceding train and the adjacent subsequent train cannot collide due to the safe separation distance. However, in some cases, a train may lose communication with the ATP system and fail to report its location to the ATP system, thus turning the train into a non-reporting train. If the non-reporting train is followed by a reporting train capable of reporting the position normally, a safety accident may occur because the ATP system cannot know the position of the non-reporting train.

Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail by referring to the following examples.
For a train Track, it includes at least two physical sections connected end to end in sequence, where the physical Section is a Track Vacancy Section (Track Vacancy Section). Each train travels along a train track. And two ends of each physical section are provided with axle counters. Through the axle counter, whether a train enters or exits the physical section can be known without communicating with the train, and the running direction of the train can be known.
Based on this, the inventor thinks of a method for determining the train moving authorization distance by using an axle counter, and adjusting the moving authorization of the reporting train behind the non-reporting train in time, thereby ensuring the safe driving of the train.
Example one
The embodiment provides a method for determining train moving authorized distance, the execution subject of the method is a device for determining train moving authorized distance, and the device can be integrated in an ATP system. More specifically, the ATP system is divided into a vehicle ATP unit and a trackside ATP unit, and the apparatus may be integrated in the trackside ATP unit. In this embodiment, "front" and "rear" are both referred to the normal traveling direction of the first target train, and the normal traveling direction of the first target train is "front".
Fig. 1 is a schematic flow chart of a method for determining an authorized train movement distance according to the present embodiment. The method comprises the following steps:
The first target train is a non-reporting train, and because it cannot report the location, it has a location loss. There are many factors that cause position loss, for example, the vehicle-mounted ATP unit cannot establish communication with the trackside ATP unit, so that the position of the train where the vehicle-mounted ATP unit is located cannot be reported to the trackside ATP unit. Since the first target train reports the position to the ATP system periodically, if the position is not reported for a while, it can be determined that the first target train has a position loss.
Two ends of the physical section are provided with axle counters, and each axle counter can detect the running direction of a train passing through the axle counter. According to different deployment modes of the axle counters on the train track, the axle counters arranged at two ends of the physical section have the following two different conditions:
the first condition is as follows: two axle counters are arranged at the junction position of two adjacent physical zones, the two axle counters belong to different physical zones respectively, each physical zone is provided with two unique axle counters, and the axle counters are not shared between the different physical zones.
Case two: only one axle counter is arranged at the junction position of two adjacent physical zones, the same axle counter belongs to two different physical zones, at the moment, the axle counter arranged at the tail of the previous physical zone is the axle counter arranged at the head of the next physical zone, namely, the train track is divided into at least two physical zones by at least three axle counters.
In summary, different physical sections can be distinguished by the axle counter.
In the invention, one axle counter comprises two sets of axle counting magnetic heads, each set of axle counting magnetic head comprises a transmitting magnetic head and a receiving magnetic head, and the two sets of axle counting magnetic heads are arranged along the extension direction of the track and have smaller spacing distance. When the train wheel passes above a set of axle counter magnetic heads, the magnetic flux received by the receiving magnetic heads in the set of axle counter magnetic heads is changed, so that a wheel axle pulse signal is obtained. The wheel axle pulse signal is transmitted to the computer host system through the electronic connection box. The computer host system can determine the running direction of the train according to the sequence of the wheel axle pulse signals generated by two sets of axle counting magnetic heads in one axle counter.
After the first target train is lost, there are many methods in the prior art to determine the first target section where the first target train is currently located, and there may be one or more first target sections. In this embodiment, one of the first target sections is taken as an example.
As an exemplary illustration, after determining that a target train is lost in a first physical section, respectively detecting the driving directions of the trains passing through an axle counter a and an axle counter B, wherein the axle counter a and the axle counter B are respectively located at two ends of the physical section where the target train is lost; and determining a first target section occupied by the first target train according to the detected driving directions of the trains passing through the A axle counter and the B axle counter. More specifically, if it is detected that at least one of the axle counter A and the axle counter B passes through the train and the passing train runs out of the first physical zone, a fifth physical zone and a sixth physical zone are determined, wherein the fifth physical zone is a physical zone which is located on one side of the axle counter A and is closest to the first physical zone and is occupied, the sixth physical zone is a physical detection zone which is located on one side of the axle counter B and is closest to the first physical zone and is occupied, the occupied state is used for representing that the train exists in the corresponding physical zone, whether the first physical zone is occupied or not is determined, and if the first physical zone is determined to be occupied, the fifth physical zone, the sixth physical zone and the first physical zone are all used as the first target zone. Alternatively, if it is identified by the a and B axle counters that no train is exiting the first physical zone, it may be determined that the first target train is still located in the first physical zone, i.e., the first physical zone is the first target zone.
For the first target train, an adjacent second target train is arranged behind the first target train, and the directions of the first target train and the second target train are consistent when the first target train and the second target train normally run. That is, the first target train is a preceding train, and the second target train is an adjacent succeeding train. The second target train is located in a second target zone, which is one of the physical zones. The physical zones in which the first target train and the second target train are located may be adjacent, for example, the second target zone is adjacent to the first target zone, and there may also be one or more physical zones between the first target train and the second target train. Generally, a first target zone in which a first target train is located and a second target zone in which a second target train is located are adjacent to each other, but if the running interval between two trains is not necessarily small for some period of time, it may occur that there are several physical zones between two trains.
The second target train is able to report the location, i.e., the first target train is a non-reporting train and the second target train is a reporting train.
And step 102, after the position of the first target train is lost, judging whether a train passes through a first axle counter and the running direction of the train is opposite to that of the first target train, wherein the first axle counter is positioned on the axle counter of the first target section close to the second target section.
For a first axle counter, if it is an axle counter belonging solely to one physical section, it is an axle counter belonging to a first target section close to a second target section, and if it is an axle counter shared by two physical sections, it is located at the intersection of the first target section and the second target section.
As an exemplary illustration, the first axle counter, after determining the direction of travel of the train, may send a signal to the means for determining the authorized distance for movement of the train. The device can determine whether the traveling direction of a train is opposite to the traveling direction of the first target train.
And 103, if the judgment result is yes, shortening the movement authorization distance of the second target train.
If the first axle counter judges that a train passes through and the running direction of the train is opposite to that of the first target train, the situation that the first target train backs up is probably described. There are many situations of this back-off, such as a forward accident, the first target train having to back-off, or the first target train losing control.
As an exemplary illustration, the second target train may be directly braked, that is, the authorized moving distance of the second target train is shortened to 0 meter, so that the safety of the second target train can be ensured to the greatest extent. Of course, the movement authorization distance of the second target train can also be shortened according to the specific situations of the first target train and the second target train.
Optionally, if the determination result in the step 102 is negative, the authorized moving distance of the second target train may reach a position of a third axle counter, where the third axle counter is located at an end of the third physical section close to the first target section, and the third physical section is adjacent to the first target section. In the prior art, when a reporting train capable of reporting a position normally follows behind a non-reporting train with a lost position, the safety separation distance between the reporting train and the non-reporting train at least comprises a completely idle and unoccupied physical zone. In this embodiment, the movement authorization distance of the rear reporting train can be directly authorized to the boundary of the physical section adjacent to the non-reporting train, and the departure interval can be reduced. As shown in fig. 2A, a first target train 201 is located at a first target segment TVS1, and a second target train at the rear may be authorized to the axle counter 231 at the interface of the second target segment TVS2 and the first target segment TVS 1.
Optionally, for the case that the first target zone and the second target zone are adjacent, the distance between the two trains is reduced, so that the cycle time of each train can be reduced, the departure distance between the trains can be shortened, and passengers can feel better. If the first target train moves backwards, the authorized moving distance of the second target train is directly shortened to 0 meter so as to avoid the collision of the trains as much as possible. Furthermore, after the first target train resumes normal driving and drives forward out of the current second target zone, that is, completely enters the first target zone again, the movement of the second target train is authorized to the axle counter at the junction of the first target zone and the second target zone.
Alternatively, if one or more physical zones are identified between the first target zone and the second target zone, the movement authorization of the second target train may be shortened to the location of a second axle counter located at an end of a fourth physical zone adjacent to the third physical zone. In this way, the first target train and the second target train can be prevented from colliding with each other as much as possible.
Optionally, if the first target train resumes the position reporting, a movement authorization distance is provided for the second target train according to the current position of the first target train. For example, the authorized distance to move of the second target train is added directly to the end of the first target train. Therefore, the interval between two adjacent trains can be shortened to the maximum extent, and the departure interval is reduced.
In the case where there are a plurality of first target sections, the above-described method may be performed for each of the first target sections.
According to the embodiment, whether the first target train backs up or not is detected through a first axle counter of a physical zone where the first target train is located, and if the first target train is detected to back up, the movement authorization of a second target train in a rear adjacent physical zone is shortened, so that collision of two trains is avoided as much as possible. And the mode is suitable for the situation that the distance between two adjacent trains is short, and the running interval of the trains can be greatly shortened by reducing the distance between the adjacent trains.
Example two
The present embodiment further exemplifies the method for determining the authorized train movement distance according to the foregoing embodiment by specific examples. In this embodiment, the first target train is a non-reporting train with a lost position, and the second target train is a reporting train capable of reporting a position normally.
For the case where the first target train and the second target train are located in adjacent physical sectors:
as shown in fig. 2A to 2C, a train is schematically driven on a train track. The first target train 201 travels in the first direction D1, and the second target train 202 trails the first target train 201, also traveling in the first direction D1. Wherein the first target train 201 is located at the first target section TVS1 and the second target train 202 is located at the second target section TVS 2. The first target section TVS1 and the second target section TVS2 are adjacent and segmented by the axle counter 231 therebetween. Fig. 2A to 2C show a case where two physical sections share one axle counter 231. Wherein, at the junction of the first target section TVS1 and the second target section TVS2 is the axle counter 231. In the figures, L1 to L6 represent logical zones, the number of logical zones and the lengths of the logical zones corresponding to each physical zone in actual situations need to be determined according to actual situations, and fig. 2A to 2C only show one example.
Fig. 2A is a schematic diagram of the first target train 201 and the second target train 202 both traveling in the first direction D1, when the movement authorization has reached the intersection of the second target segment TVS2 and the first target segment TVS1, as indicated by arrow T in fig. 2A. Fig. 2B is a schematic diagram of the first target train 201 backing up. Figure 2C is a schematic diagram of the authorized distance for movement of the second target train 202 being reduced to 0 meters.
After the first target train 201 is lost, it is judged that it should be located in the first target segment TVS1 at present. The trackside ATP unit (not shown) determines whether the first target train 201 is backing up by detection of the axle counter 231. If it is recognized that a train enters the first target section TVS1 in the first direction D1 but does not exit the first target section TVS1 and it is monitored that the train passes through the axle counter 231 in the second direction D2, it is determined that the first target train 201 backs up, as shown in fig. 2B. Wherein the first direction D1 and the second direction D2 are opposite. Whether a train enters or exits a physical section can be detected by the axle counters 231 at two ends of the physical section, and how to detect the train belongs to the prior art, which is not described herein again. It is judged that the first target train 201 is backed, that is, the first target train 201 is highly likely to have entered the second target segment TVS 2.
At this time, the trackside ATP unit shortens the movement authorized distance of the second target train 202, for example, directly to 0 meter, as indicated by arrow T in fig. 2C. After receiving the movement authorization distance, the second target train 202 immediately starts braking to avoid an accident.
After the first target train 201 resumes the position reporting, the trackside ATP unit may allocate a movement authorization distance to the second target train 202 according to the current position of the first target train 201. For example, a first target train 201 and a second target train 202 are located in different physical sectors, and the second target train 202 is authorized to the end of the first target train 201.
For the case where there are one or more physical zones between the first target train and the second target train:
as shown in fig. 2D to 2F, the train is schematically driven on the train track. The first target train 203 travels in a first direction D1 and the second target train 204 trails the first target train 203, also traveling in a first direction D1. Wherein the first target train 203 is located in the first target section TVS1, the second target train is located in the second target section TVS4, and two physical sections, a third physical section TVS2 and a fourth physical section TVS3, are spaced between the first target train 203 and the second target train 204. Fig. 2D to 2F show a case where two physical sections share one axle counter 232. As an exemplary illustration, L1 to L6 in the figure represent each logical partition, and in actual situations, the number of logical partitions corresponding to each physical partition and the length of each logical partition need to be determined according to actual situations.
Fig. 2D is a schematic diagram of the first target train 203 and the second target train 204 both traveling in the first direction D1 when the movement authorization has arrived at the boundary of L6 at the axle counter 232 in the third physical segment TVS2, as indicated by arrow T in fig. 2D. Fig. 2E is a schematic diagram of the first target train 201 backing up. Fig. 2F is a schematic diagram of the axle counter 232 of the second target train 204 with its authorized movement distance reduced by the fourth physical section TVS3 near the third physical section TVS2 side.
After the first target train 203 is lost, it is determined that it is currently located in the first target segment TVS 1. The trackside ATP unit (not shown) determines whether the first target train 203 is backing up by detection of the axle counter 232. If it is recognized that a train enters the first target section TVS1 in the first direction D1 but does not exit the first target section TVS1 and it is monitored that the train passes through the axle counter 232 in the second direction D2, it is determined that the first target train 203 backs up, as shown in fig. 2E. Wherein the first direction D1 and the second direction D2 are opposite, that is, the first target train 203 is likely to have entered the third physical segment TVS 2. Whether a train enters or exits a physical section can be detected through the axle counters 232 at two ends of the physical section, and how to detect the train belongs to the prior art, and details are not described herein.
Next, the trackside ATP unit detects whether the movement authorization of the second target train 204 has reached the third physical segment TVS2, and as can be seen from fig. 2D and 2E, the movement authorization distance has reached the third physical segment TVS2, so that it is required to shorten the movement authorization distance to the axle counter 232 shared between the fourth physical segment TVS3 and the third physical segment TVS2, i.e., to prohibit the second target train 204 from entering the third physical segment TVS2, so as to avoid collision with the first target train 203.
Likewise, after the first target train 203 resumes position reporting, the trackside ATP unit may assign a movement authorization distance to the second target train 204 based on the current position of the first target train 203. For example, the first target train 203 and the second target train 204 are located in different physical sectors, and the second target train 204 is authorized to the end of the first target train 203.
