Description

Technical Field

[0001] The present invention relates to the field of rail transit technology, and in particular to a train tail retraction method, a train operation control system, an electronic device and a readable storage medium. Background Art

[0002] At present, the train operation control system calculates the rear position of the train as follows: the staff inputs the number of train formations and converts it into the train length; then the rear position of the train is obtained based on the front position of the train and the length of the train. The rear position of the train is the basis for tracking the front and rear trains under moving blocks, and has a crucial impact on the efficiency of train tracking.

[0003] For EMU trains, the trains are fixed in formation and the train length is fixed. The train tail position obtained by the above method is relatively accurate. However, for locomotives, shunting and uncoupling operations are frequent. After uncoupling and uncoupling are completed, the train formation number is not fixed, and it is difficult for staff to input the accurate formation number. As a result, the train length automatically calculated by the above method usually has a certain error, which may cause the calculated train length to be longer than the actual train length, that is, the calculated train tail position is further back than the actual train tail, resulting in reduced train tracking efficiency; especially in the case of blocked access to the station, if the tail of the leading train lags behind, it may cause the following train to be unable to receive the train and enter the station normally, affecting the operation efficiency within the station. Summary of the invention

In the absence of further restrictions, the elements defined by the sentence "comprise a ..." do not exclude the existence of other identical elements in the process, method, article or device including the elements.

[0064] Combined with Figures 1 to 10 As shown, this embodiment provides a train tail retraction method, which is applied to a train operation control system. The train operation control system includes a radio block center device and an interlocking device that is communicatively connected to the radio block center device; wherein the interlocking device is arranged in a station. The train tail retraction method includes:

[0065] Step S11: The current train and the train in the next sequence are running in the section or station, and the interlocking device is used to process the first train route ahead for the current train; and the types of the first train route include the receiving route and the departure route. It can be understood that the interlocking device processes the first train route for the current train, indicating that the first train route is not occupied by other trains.

[0066] Step S12: the current train runs along the first train route, and the radio block center equipment calculates the tail position of the current train in real time and sends it to the interlocking device.

[0067] 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 a track within the range of the first train route, or the first train route is a departure route and the tail of the current train exits the first train route, the interlocking device sends a signal to the wireless block center device that the status of the first train route is inactivated.

[0068] Step S14: When the state of the first train route is inactive, the radio block center equipment retracts the calculated tail position of the current train to the track entrance or the reverse station entry signal within the range of the first train route according to the type of the first train route; wherein the reverse station entry signal is an entry signal in the opposite direction of the current train running direction.

[0069] Step S15: After the calculated tail position of the current train is retracted, the radio block center equipment may extend the driving permission of the subsequent train to the route range of the first train.

[0070] Specifically, the train operation control system also includes an on-board device that is communicatively connected to the wireless block center device; the on-board device is arranged in the driver's cab of the train and is used to obtain the position information of the train. More specifically, in step S12, the step of the wireless block center device calculating the tail position of the current train in real time includes: step S121, obtaining the position information of the current train through the on-board device and sending it to the wireless block center device; step S122, the wireless block center device calculates the tail position of the current train according to 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, in which case 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 technology section, due to the existence of calculation errors, the calculated tail position of the current train (such as Figure 2 a2) is usually larger than the tail of the current train (such as Figure 2 The illustrated a1) is further back, but the present invention is not limited thereto.

[0071] Furthermore, in some embodiments, before executing step S13, the step further includes: the radio block center device determines whether the current train enters the first train route according to the position information of the current train; if the current train enters the first train route, the interlocking device sends a message to the radio block center device indicating that the status of 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.

[0072] Specifically, in step S13, when the first train route is a receiving train route, the interlocking device monitors that the tail of the current train enters the track within the range of the first train route, and the tail position of the current train calculated by the wireless block center device is located within the first train route, which means that due to a calculation error, the tail of the current train has actually entered the track within the range of the first train route, but the calculated tail position 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 wireless block center device as inactivated.

[0073] When the first train route is a departure route, the interlocking device monitors that the tail of the current train has left the first train route, and the tail position of the current train calculated by the wireless block center device is within the first train route, which means that due to a calculation error, the current train has actually completely left the first train route, but the calculated tail position of the current train is still on the first train route; in this case, the interlocking device sends the status of the first train route to the wireless block center device as inactivated.

[0074] Specifically, in step S14, after the RBC device receives that the state of the first train route is inactive, if the first train route is a train receiving route, the RBC device retracts 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 RBC device retracts the calculated tail position of the current train to the reverse station entry signal; it can be understood that the first train route is a departure route, and there can only be one line corresponding to the departure route, so there is only one reverse station entry signal.

[0075] From the above, it can be seen that in this embodiment, according to the route status information sent by the interlocking device, the radio block center device can retract the calculated tail position of the current train to release the route resources, so that the driving permit of the subsequent train can be extended into the route, and the subsequent train can be normally received and enter the station, thereby solving the problem of reduced tracking efficiency in the prior art due to the calculated train tail position being further back than the actual train tail, thereby reducing the impact of the current train on the subsequent train and improving the operation efficiency in the station.

[0076] It can be understood that, in some embodiments, the train tail retraction method further includes:

[0077] Step S16: When the calculated tail position of the current train is within the first train approach, if the first train approach is a receiving route and the tail of the current train has not entered a track within the range of the first train approach, or the first train approach is a departure route and the tail of the current train has not left the first train approach, the interlocking device sends a message to the wireless block center device that the status of the first train approach is in use.

[0078] Step S17, the interlocking device processes the second train route ahead for the subsequent train, and the interlocking device sends a normal status of the second train route to the wireless block center device; it can be understood that the interlocking device processes the second train route for the subsequent train, indicating that the second train route is not occupied by other trains.

[0079] Step S18: The radio block center equipment compares the first train route with the second train route to determine whether there is an overlapping section between the first train route and the second train route.

[0080] Step S19: When there is an overlapping section between the first train route and the second train route, the radio block center equipment retracts the calculated tail position of the current train to the exit of the overlapping section.

[0081] Step S20: After the calculated tail position of the current train is retracted, the radio block center equipment extends the driving permission of the subsequent train to the overlapping section.

[0082] In addition, 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 train to the second train route.

[0083] 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 tail position of the current train calculated by the radio block center device is located 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 tail position of the current train calculated by the radio block center device is located within the first train route; this means that due to the long length of the current train, the current train cannot completely leave the first train route. It is understandable that this may be because the current train stops at the track, and since the length of the current train is greater than the length of the track, the tail of the current train and the calculated tail position of the current train are both within the first train route. In this case, the interlocking device sends to the radio block center device that the status of the first train route is in use.

[0084] It can be understood that, in some embodiments, the train tail retraction method also includes: step S21, the tail of the current train drives out of the first train route and the calculated tail position of the current train is not located in the first train route, and the interlocking device sends a message to the wireless block center device that the status of the first train route is normal; step S22, the wireless block center device extends the driving permission of the subsequent train to the first train route.

[0085] In order to explain the train tail retraction method in more detail, the present invention is described through the following embodiments. Figure 2As shown in the figure, the current train A and the subsequent train B are tracking each other in the section, and the interlocking equipment processes the first train route X-XI for the current train A, which ranges from the station entry signal X to the station exit signal XI (including the IG track) on the IG track, and the first train route X-XI is the train receiving route. Figure 3 As shown, the on-board 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 enters 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. Thereafter, according to whether the tail a1 of the current train A enters the IG track of the first train route X-XI, whether it exits 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, it can be divided into the following three situations.

[0086] First case:

[0087] like Figure 4 As shown, 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 device sends the status of the first train route X-XI to the wireless block center device as inactivated.

[0088] like Figure 5 As shown in FIG. 1 , after the RBC equipment receives that the status of the first train route X-XI is inactive, since the first train route X-XI is a train receiving route, the RBC equipment retracts the calculated tail position a2 of the current train A to the entrance of the IG track (as shown in FIG. 1 ). Figure 5 (at the signal SI in the middle).

[0089] The interlocking equipment processes the second train route X-X2 for the rear-series car B, and the route range is from the station entry signal X to the station exit signal X2 on the IIG track (including the IIG track); and the radio block center equipment can normally extend the driving permission of the rear-series car B to the range of the first train route X-XI (for example Figure 5 The XAG section and 1DG section in the train route and the second train route X-X2, i.e., within the station, will not affect the operation of the subsequent train B within the station.

[0090] Second case:

[0091] like Figure 6 As shown, 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 device sends the status of the first train route X-XI to the wireless block center device as being in use.

[0092] The interlocking equipment processes the second train route X-X2 for the rear-sequence car B, and the route range is from the entrance signal X to the exit signal X2 on the IIG track (including the IIG track); and the interlocking equipment sends the status of the second train route X-X2 to the radio block center equipment as normal.

[0093] The wireless block center equipment compares the first train route X-XI with the second train route X-X2, and determines that there are overlapping sections XAG (i.e., the inner section of the station entrance signal) and 1DG (i.e., the section with a switch) between the first train route X-XI and the second train route X-X2.

[0094] like Figure 7 As shown, the RBC equipment retracts the calculated tail position a2 of the current train A to the exit of the overlapping section, i.e., the exit of the IDG, and can extend the driving permission of the subsequent train B normally to the overlapping section, i.e., the station, without affecting the operation of the subsequent train B in the station.

[0095] The third case:

[0096] like Figure 8 As shown, the tail a1 of the current train A has driven out of 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 device sends a message to the radio block center device that the status of the first train route X-XI is normal; and the radio block center device can extend the driving permission of the subsequent train B to the first train route X-XI.

[0097] In addition, if Fig. 9 As shown in the figure, if the first train route (XI-S3) is the departure route, 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), then the interlocking device sends the status of the first train route (XI-S3) to the radio block center device as inactive. Fig.10 As shown, after the RBC equipment receives that the status of the first train route (XI-S3) is inactive, the RBC equipment retracts the calculated tail position of the current train A to the reverse station entry signal S3. After the calculated tail position of the current train A is retracted, the RBC equipment can extend the driving permission of the subsequent train B to the first train route (XI-S3) normally, without affecting the in-station operation of the subsequent train B.

[0098] Based on the same inventive concept, this embodiment also provides a train operation control system, including: an interlocking device and a radio block center device; the interlocking device is set at a station and is used to handle the first train route ahead for the current train; and the types of the first train route include a receiving route and a departure route. The radio block center device is connected to the interlocking device in communication; and when the current train runs along the first train route, the radio block center device is used to calculate the tail position of the current train in real time;

[0099] 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 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 used to send to the radio block center device that the state of the first train route is inactive. When the state of the first train route is inactive, the radio block center device is further used to retract the calculated tail position of the current train to the track entrance or the reverse station entry signal within the range of the first train route according to the type of the first train route and extend the driving permission of the subsequent train to the first train route.

[0100] Specifically, the first train route is a receiving route, and the wireless 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 wireless block center equipment is used to retract the calculated tail position of the current train to the reverse entry signal.

[0101] 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 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 used to send to the radio block center device that the state of the first train route is in use, and to handle the second train route ahead for the subsequent train and send to the radio block center device that the state of the second train route is normal. The radio block center device is also used to compare the first train route with the second train route to determine whether there is an overlapping section between the first train route and the second train route; and when there is an overlapping section between the first train route and the second train route, the radio block center device is also used to retract the calculated tail position of the current train to the exit of the overlapping section and extend the driving permission of the subsequent train to the overlapping section. In addition, 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.

[0102] Specifically, the tail of the current train drives out of the first train route and the calculated tail position of the current train is not located in the first train route, and the interlocking device is further used to send a message to the wireless block center device indicating that the status of the first train route is normal; the wireless block center device is further used to extend the driving permission of the subsequent train to the first train route.

[0103] Specifically, the train operation control system further includes an on-board device that is communicatively connected to the radio block center device; the on-board device is used to obtain the position information of the current train and send it to the radio block center device, so that the radio block center device calculates the tail position of the current train according to the position information of the current train. Optionally, 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.

[0104] In addition, the wireless block center device is also used to determine whether the current train enters the first train route based on the position information of the current train; and when the current train enters the first train route, the interlocking device is also used to send a message to the wireless block center device indicating that the status of the first train route is in use.

[0105] It can be understood that, in addition to the roles or functions described in this embodiment, the interlocking device, the radio block center device and the vehicle-mounted device should also have the roles or functions involved in the prior art, which will not be repeated here.

[0106] Based on the same inventive concept, this embodiment further 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, the method described above is implemented.

[0107] Based on the same inventive concept, this embodiment further provides a readable storage medium, in which a computer program is stored. When the computer program is executed by a processor, the method described above is implemented.

[0108] In summary, the present embodiment provides a method for retracting the tail of a train. According to the route status information of the interlocking device, the radio block center device can retract the calculated tail position of the current train to release the route resources, so that the driving permit of the subsequent train can be extended into the route, and the normal train reception and entry of the subsequent train can be realized, thereby solving the problem of reduced tracking efficiency caused by the calculated tail position of the train being further back than the actual tail position of the train in the prior art, thereby reducing the impact of the current train on the subsequent train and improving the operation efficiency in the station. In the present embodiment, according to the route status information of the interlocking device, the radio block center device can also judge the overlapping sections of multiple routes, and can also retract the calculated tail position of the current train when there are overlapping sections, thereby reducing the impact of the current train on the subsequent train under the premise of ensuring safety, and improving the availability of the line and the operation efficiency in the station. In addition, in the present embodiment, the staff can more flexibly input the number of train formations or the length of the train after completing the unhooking and unhooking operation, thereby reducing the manual workload.

After reading the above content, it will be apparent to those skilled in the art that various modifications and substitutions of the present invention will occur.
