Description

Train tail retraction method, train operation control system, electronic equipment and readable storage medium Technical Field

[0001] This invention relates to the field of rail transit technology, and in particular to a method for retracting the rear of a train, a train operation control system, electronic equipment, and a readable storage medium. Background Technology

[0002] Currently, the train control system calculates the rear position of a train as follows: staff input the number of train formations, which is then converted to the train length; finally, based on the position of the train's front and the train's length, the rear position is obtained. The rear position of the train serves as the basis for tracking preceding and following trains under moving block signaling, and has a crucial impact on train tracking efficiency.

[0003] For high-speed trains, the trains have a fixed formation and a constant length, making the rear position obtained using the above method relatively accurate. However, for locomotives, shunting and uncoupling operations are frequent. After uncoupling and uncoupling, the number of train formations is not fixed, and it is difficult for staff to input the accurate number of formations. This often results in an error in the automatically calculated train length using the above method, which may lead to a calculated train length that is longer than the actual train length, meaning the calculated rear position of the train is further back than the actual rear. This reduces train tracking efficiency. Especially when the station route is blocked, if the rear of the preceding train lags behind, subsequent trains may not be able to receive the train and enter the station normally, affecting the station's operational efficiency. Technical issues

[0004] The purpose of this invention is to provide a train tail retraction method, a train operation control system, electronic equipment, and a readable storage medium to solve the problem of reduced tracking efficiency caused by the calculated train tail position being further back than the actual train tail position.

[0030] Optionally, the current train's position information is the head position of the current train, and the sum of the head position of the current train and the length of the current train is the calculated tail position of the current train.

[0034] When the calculated tail position of the current train is within the first train route, if the first train route is a receiving route and the tail of the current train enters the track within the range of the first train route, or if the first train route is a departure route and the tail of the current train leaves the first train route, the interlocking device is also used to send the status of the first train route as inactive to the radio block center device.

[0035] When the first train route is inactive, the wireless block center equipment is further configured to, based on the type of the first train route, retract the calculated tail position of the current train to the track entrance or the reverse entry signal within the range of the first train route, and extend the driving permission of the following trains to the range of the first train route.

[0038] Optionally, when the calculated tail position of the current train is within the first train route, if the first train route is a receiving route and the tail of the current train has not entered the track within the range of the first train route, or if the first train route is a departure route and the tail of the current train has not left the first train route, the interlocking device is further configured to send the status of the first train route to the radio block center device as being in use, and to process the second train route ahead for the following train and send the status of the second train route to the radio block center device as being normal;

[0061] The following detailed description, in conjunction with the accompanying drawings and specific embodiments, provides a further detailed explanation of the train tail retraction method, electronic device, and readable storage medium proposed by the present invention. The advantages and features of the present invention will become clearer from the following description.

Therefore, they have no substantial technical significance. Any modifications to the structure, changes in proportions, or adjustments to the size, without affecting the effects and objectives achieved by the present invention, should still fall within the scope of the technical content disclosed in the present invention.

[0062] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitations, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0063] Referring to Figures 1-10, this embodiment provides a train tail retraction method applied to a train operation control system. The train operation control system includes a radio block center device and interlocking equipment communicatively connected to the radio block center device; wherein the interlocking equipment is located within a station. The train tail retraction method includes:

[0064] Step S11: The current train and the following trains are running within the section or station. The interlocking equipment processes the first train route for the current train; and the type of the first train route includes receiving routes and departure routes. It can be understood that the interlocking equipment processes the first train route for the current train, indicating that the first train route is not occupied by other trains.

[0065] Step S12: The current train runs along the route of the first train, and the wireless block center device calculates the tail position of the current train in real time and sends it to the interlocking device.

[0066] Step S13: When the calculated tail position of the current train is within the first train route, if the first train route is a receiving route and the tail of the current train enters the track within the range of the first train route, or if the first train route is a departure route and the tail of the current train leaves the first train route, then the interlocking device sends the status of the first train route to the radio block center device as inactive.

[0067] Step S14: When the first train route is inactive, the wireless block center device, based on the type of the first train route, retracts the calculated tail position of the current train to the track entrance or the reverse entry signal within the range of the first train route; wherein, the reverse entry signal is the entry signal in the opposite direction to the current train's running direction.

[0068] Step S15: After the calculated tail position of the current train is retracted, the radio block center equipment can extend the driving permission of the following train to the route range of the first train.

[0069] Specifically, the train operation control system further includes onboard equipment communicatively connected to the radio block center device; the onboard equipment is installed in the driver's cab of the train and is used to acquire the train's position information. More specifically, in step S12, the step of the radio block center device calculating the tail position of the current train in real time includes: step S121, acquiring the position information of the current train through the onboard equipment and sending it to the radio block center device; step S122, the radio block center device calculating the tail position of the current train based on the position information of the current train. Optionally, in some embodiments, the position information of the current train is the head position of the current train, and the sum of the head position of the current train and the length of the current train is the calculated tail position of the current train. However, as described in the background section, due to calculation errors, the calculated tail position of the current train (as shown in Figure 2, a2) is usually further back than the tail of the current train (as shown in Figure 2, a1), but the present invention is not limited thereto.

[0070] Furthermore, in some embodiments, before performing step S13, the method further includes: the radio block center device determining whether the current train has entered the first train route based on the current train's location information; if the current train has entered the first train route, the interlocking device sends a message to the radio block center device indicating that the first train route is in use; and the radio block center device monitors the status of the first train route in real time, but the present invention is not limited thereto.

[0071] Specifically, in step S13, when the first train route is a receiving route, the interlocking device detects that the tail of the current train has entered the track within the range of the first train route, and the position of the tail of the current train calculated by the radio block center device is within the first train route. This indicates that due to calculation errors, the tail of the current train has actually entered the track within the range of the first train route, but the calculated position of the tail of the current train is still in the non-track area of ​​the first train route. In this case, the interlocking device sends the status of the first train route to the radio block center device as inactive.

[0072] When the first train route is a departure route, if the interlocking equipment detects that the tail of the current train has left the first train route, and the radio block center equipment calculates that the tail position of the current train is within the first train route, this indicates that due to calculation errors, the current train has actually completely left the first train route, but the calculated tail position of the current train is still within the first train route. In this case, the interlocking equipment sends the status of the first train route to the radio block center equipment as "inactive".

[0073] Specifically, in step S14, after the radio block center device receives the status of the first train route as inactive, if the first train route is a receiving route, the radio block center device will retract the calculated tail position of the current train to the track entrance within the range of the first train route. If the first train route is a departure route, the radio block center device will retract the calculated tail position of the current train to the reverse entry signal. It can be understood that if the first train route is a departure route, there can only be one corresponding line, therefore there is only one reverse entry signal.

[0074] As can be seen from the above, in this embodiment, based on the route status information sent by the interlocking equipment, the wireless block center equipment can retract the calculated tail position of the current train to release route resources, allowing the driving permission of the following trains to extend into the route, enabling the following trains to receive and enter the station normally. This solves the problem of reduced tracking efficiency caused by the calculated tail position of the train being further back than the actual tail position in the prior art, thereby reducing the impact of the current train on the following trains and improving the station's operating efficiency.

[0075] It is understood that, in some embodiments, the train tail retraction method further includes:

[0076] Step S16: When the calculated tail position of the current train is within the first train route, if the first train route is a receiving route and the tail of the current train has not entered the track within the range of the first train route, or if the first train route is a departure route and the tail of the current train has not left the first train route, then the interlocking equipment sends the status of the first train route to the radio block center equipment as being in use.

[0077] Step S17: The interlocking device processes the second train route for the following train, and the interlocking device sends the status of the second train route to the radio block center device as normal; it can be understood that the interlocking device processing the second train route for the following train indicates that the second train route is not occupied by other trains.

[0078] Step S18: The wireless block center device compares the first train route and the second train route to determine whether there is an overlapping section between the first train route and the second train route.

[0079] Step S19: When there is an overlapping section between the first train route and the second train route, the radio block center device will retract the calculated tail position of the current train to the exit of the overlapping section.

[0080] Step S20: After the calculated tail position of the current train is retracted, the radio block center equipment extends the driving permission of the following trains to the overlapping section.

[0081] Furthermore, when there is no overlapping section between the first train route and the second train route, the radio block center equipment directly extends the driving permission of the subsequent trains to the second train route.

[0082] Specifically, in step S16, when the first train route is a receiving route, the interlocking device detects that the tail of the current train has not entered the track within the range of the first train route, and the position of the tail of the current train calculated by the radio block center device is within the first train route; or, when the first train route is a departure route, the interlocking device detects that the tail of the current train has not left the first train route, and the position of the tail of the current train calculated by the radio block center device is within the first train route. This indicates that because the current train is relatively long, it cannot completely leave the first train route. It is understandable that this situation may occur because the current train is stopped on the track, and because the length of the current train is greater than the length of the track, both the tail of the current train and the calculated position of the tail of the current train are within the first train route. In this case, the interlocking device sends the status of the first train route to the radio block center device as "in use".

[0083] It is understood that, in some embodiments, the train tail retraction method further includes: step S21, the tail of the current train leaves the first train route and the calculated tail position of the current train is not within the first train route, and the interlocking device sends a message to the radio block center device that the status of the first train route is normal; step S22, the radio block center device extends the driving permission of the subsequent trains to the first train route.

[0084] To illustrate the train tail retraction method in more detail, the present invention is explained through the following embodiments. As shown in Figure 2, the current train A and the following train B are tracking each other in the section. The interlocking equipment assigns the first train route X-XI to the current train A. This route extends from the entry signal X to the exit signal XI on the IG track (including the IG track), and the first train route X-XI is a receiving route. Subsequently, as shown in Figure 3, the onboard equipment sends the position information of the current train A to the radio block center equipment. The radio block center equipment determines that the current train A has entered the first train route X-XI, and the interlocking equipment sends the status of the first train route X-XI to the radio block center equipment as being in use. Afterwards, based on whether the tail a1 of the current train A has entered or exited the IG track of the first train route X-XI, and whether the calculated tail position a2 of the current train A is within the first train route X-XI, the following three cases can be identified.

[0085] First scenario:

[0086] As shown in Figure 4, the tail a1 of the current train A enters the IG track of the first train route X-XI, and the calculated tail position a2 of the current train A is within the first train route X-XI. At this time, the interlocking equipment sends the status of the first train route X-XI to the radio block center equipment as inactive.

[0087] As shown in Figure 5, after the radio block center equipment receives the status of the first train route X-XI as inactive, since the first train route X-XI is the receiving route, the radio block center equipment will retract the calculated tail position a2 of the current train A to the entrance of track IG (at the signal SI in Figure 5).

[0088] The interlocking equipment provides the following train B with a second train route X-X2, which extends from the entrance signal X to the exit signal X2 on the IIG track (including the IIG track). The radio block center equipment can extend the train operation permission of the following train B normally to the range of the first train route X-XI (e.g., the XAG section and 1DG section in Figure 5) and the second train route X-X2, i.e., within the station, without affecting the station operation of the following train B.

[0089] The second scenario:

[0090] As shown in Figure 6, the tail a1 of the current train A has not entered the IG track of the first train route X-XI, and the calculated tail position a2 of the current train A is within the first train route X-XI. At this time, the interlocking equipment sends the status of the first train route X-XI to the radio block center equipment as being in use.

[0091] The interlocking equipment assigns a second train route X-X2 to the following train B. This route extends from the entrance signal X to the exit signal X2 on the IIG track (including the IIG track); and the interlocking equipment sends a message to the radio block center indicating that the second train route X-X2 is in normal condition.

[0092] The wireless block center equipment compares the first train route X-XI and the second train route X-X2, and determines that the first train route X-XI and the second train route X-X2 have overlapping sections XAG (i.e., the section inside the station signal) and 1DG (i.e., the section with one turnout).

[0093] As shown in Figure 7, the wireless block center equipment will retract the calculated tail position a2 of the current train A to the exit of the overlapping section, i.e., the exit of IDG, and can extend the train permit of the following train B normally to the overlapping section, i.e., within the station, without affecting the station operation of the following train B.

[0094] The third scenario:

[0095] As shown in Figure 8, the tail a1 of the current train A has left the first train route X-XI, and the calculated tail position a2 of the current train A is not within the first train route X-XI. At this time, the interlocking equipment sends the status of the first train route X-XI to the radio block center equipment as normal; and the radio block center equipment can extend the driving permission of the following train B to the first train route X-XI.

[0096] Furthermore, as shown in Figure 9, if the first train route (XI-S3) is a departure route, and the tail a1 of the current train A has completely left the first train route (XI-S3), but the calculated tail position a2 of the current train A is still within the first train route (XI-S3), the interlocking equipment sends the status of the first train route (XI-S3) to the radio block center equipment as inactive. As shown in Figure 10, after the radio block center equipment receives the status of the first train route (XI-S3) as inactive, it retracts the calculated tail position of the current train A to the reverse entry signal S3. After the calculated tail position of the current train A is retracted, the radio block center equipment can normally extend the train permission of the following train B to the first train route (XI-S3) without affecting the station operation of the following train B.

[0097] Based on the same inventive concept, this embodiment also provides a train operation control system, including: interlocking equipment and wireless block center equipment; the interlocking equipment is installed at the station and is used to process the route of the first train ahead for the current train; and the type of the first train route includes a receiving route and a departure route. The wireless block center equipment is communicatively connected to the interlocking equipment; and when the current train is running along the first train route, the wireless block center equipment is used to calculate the tail position of the current train in real time;

[0098] When the calculated tail position of the current train is within the first train route, if the first train route is a receiving route and the tail of the current train enters the track within the range of the first train route, or if the first train route is a departure route and the tail of the current train exits the first train route, the interlocking device is further configured to send a message to the radio block center device indicating that the status of the first train route is inactive. When the status of the first train route is inactive, the radio block center device is further configured to, according to the type of the first train route, retract the calculated tail position of the current train to the track entrance or the reverse entry signal within the range of the first train route and extend the driving permission of the following trains to the first train route.

[0099] Specifically, the first train route is a receiving route, and the radio block center equipment is used to retract the calculated tail position of the current train to the track entrance within the range of the first train route; the first train route is a departure route, and the radio block center equipment is used to retract the calculated tail position of the current train to the reverse entry signal.

[0100] Specifically, when the calculated tail position of the current train is within the first train route, if the first train route is a receiving route and the tail of the current train has not entered the track within the range of the first train route, or if the first train route is a departure route and the tail of the current train has not left the first train route, the interlocking device is further configured to send the status of the first train route to the radio block center device as "in use," and to process the second train route ahead for the following train and send the status of the second train route to the radio block center device as "normal." The radio block center device is further configured to compare the first train route and the second train route to determine whether there is an overlapping section between the first train route and the second train route; and if there is an overlapping section between the first train route and the second train route, the radio block center device is further configured to retract the calculated tail position of the current train to the exit of the overlapping section and extend the driving permission of the following train to the overlapping section. Furthermore, when there is no overlapping section between the first train route and the second train route, the radio block center equipment is also used to extend the driving permission of the subsequent train to the second train route.

[0101] Specifically, if the tail of the current train leaves the first train route and the calculated tail position of the current train is not within the first train route, the interlocking device is also used to send a message to the radio block center device that the status of the first train route is normal; the radio block center device is also used to extend the driving permission of the subsequent trains to the first train route.

[0102] Specifically, the train operation control system further includes onboard equipment communicatively connected to the radio block center equipment; the onboard equipment is used to acquire the current train's position information and send it to the radio block center equipment, so that the radio block center equipment can calculate the rear position of the current train based on the current train's position information. Optionally, the current train's position information is the head position of the current train, and the sum of the head position of the current train and the length of the current train is the calculated rear position of the current train.

[0103] In addition, the radio block center equipment is also used to determine whether the current train has entered the first train route based on the current train's location information; and if the current train enters the first train route, the interlocking equipment is also used to send a message to the radio block center equipment that the first train route is in use.

[0104] It is understood that, in addition to the functions or roles described in this embodiment, the interlocking equipment, the wireless block center equipment, and the vehicle-mounted equipment should also have the functions or roles involved in the prior art, which will not be repeated here.

[0105] Based on the same inventive concept, this embodiment also provides an electronic device, including a processor and a memory, wherein a computer program is stored in the memory, and when the computer program is executed by the processor, it implements the method described above.

[0106] Based on the same inventive concept, this embodiment also provides a readable storage medium storing a computer program, which, when executed by a processor, implements the method described above.

[0107] In summary, the train tail retraction method provided in this embodiment allows the radio block center equipment to retract the calculated tail position of the current train based on the route status information of the interlocking equipment. This releases route resources, enabling subsequent trains to extend their travel permits into the route and allowing them to receive and enter the station normally. This solves the problem of reduced tracking efficiency caused by the calculated train tail position being further back than the actual train tail position in existing technologies, thereby reducing the impact of the current train on subsequent trains and improving station operating efficiency. In this embodiment, based on the route status information of the interlocking equipment, the radio block center equipment can also determine overlapping sections across multiple routes. When overlapping sections exist, it can also retract the calculated tail position of the current train, thus reducing the impact of the current train on subsequent trains while ensuring safety, improving line availability and station operating efficiency. Furthermore, this embodiment allows staff to input the train formation number or train length more flexibly after completing the coupling / uncoupling operations, reducing manual workload.

Various modifications and substitutions to the present invention will be apparent to those skilled in the art after reading the above description. Therefore, the scope of protection of the present invention should be defined by the appended claims.
