Description

Technical Field

[0001] The present application relates to the field of rail transit technology, and in particular to a train change control method, device and equipment. Background Art

[0002] In the management of train operation, in order to ensure the safety of train travel, the track operation status of each section will be detected. During the detection process, the main purpose is to detect whether the relay of the track in the current section is normally energized. Among them, the detection process of each section needs to use the information provided by the previous section as an aid to realize the detection of the operation status of the section. In other words, if the previous section fails to send relevant instructions or information to the current section in time, or for some reason the current section fails to receive the relevant information or instructions sent by the previous section in time, it will affect the detection result of the operation status of the current section. Specifically, the relevant information or instructions sent by the previous section can actually be the track relay control instructions of the small track circuit sent by the signal receiver of the previous section, and the control instructions will control whether the relay in the track is normally energized.

[0003] At present, when a train is running, it is necessary to adjust the running direction of the train in some cases, that is, to change the direction of the train. For example, assuming that there are two stations A and B, station A is changed from a departure station to a receiving station, and station B is changed from a receiving station to a departure station, then the running direction of the train will be changed from A to B to B to A. In this process, for the track signal detection system, once the train changes direction, the tracks of each section need to be reconfigured to adapt to the new running direction, but there may be a short signal processing delay in this reconfiguration process. However, during this delay period, the track of some sections will not be able to obtain the track relay control instructions sent by the previous section in time due to the change of direction. The track relay of this section will not be able to be energized and attracted and alarm, resulting in the track section showing a red flashing band on the console, commonly known as "flashing red". This means that even if the track of the section has been reconfigured, the "flashing red" problem will still affect the smooth progress of the train change. Summary of the invention

This can ensure that during the redirection process, the situation in which the current section cannot be reset in time and the current section cannot be issued as being in a non-occupied state is avoided. This also avoids the situation in which the current track section cannot be reset in time and the original track relay cannot be energized and "flashes red". This further avoids the smooth implementation of the train redirection process being affected by the "flashing red" situation in the track section, thereby ensuring the smooth execution of the train redirection process. In addition, since the current section can replace the operating status of the track relay in the current section based on the first control instruction, this avoids the situation where the operating information of the track relay in this section cannot be sent out in time in certain cases. It can also be replaced based on the first control instruction, ensuring that the target section can also smoothly perform track detection operations, thereby reducing the "flashing red" phenomenon in subsequent target sections to a certain extent, and further improving the smooth execution of the train change process.

[0055] The exemplary embodiments of the present application will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present application are shown in the accompanying drawings, it should be understood that the present application can be implemented in various forms and should not be limited by the embodiments described herein. On the contrary, these embodiments are provided in order to enable a more thorough understanding of the present application and to fully convey the scope of the present application to those skilled in the art.

[0056] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which this application belongs.

[0057] The present application provides a train change control method, specifically, Figure 1 As shown, the method is applied to a modified control device, and the modified control device is connected in parallel with a track relay in a small track circuit of a train section; the method comprises:

[0058] 101. Detect whether a change instruction is received from a signal receiver in the current section.

[0059] The change direction instruction is used to modify the running direction of the train.

[0060] Assume that the train runs between Station A and Station B, where the two stations contain sections of tracks 1G, 3G, 5G, 7G, 9G, 11G, and 13G in sequence, among which 7G and 9G are located at relay stations, such as Figure 2 As shown, currently, the situations where red flashes appear during the existing modification process are mainly divided into the following categories:

[0061] On the one hand, when the train is running in the forward direction (from Station B to Station A) on the railway, the 1G section needs the instruction information provided by the section behind it, 3G, as auxiliary information during the track self-inspection process (specifically, the instruction information can be the operating status of the track relay in the 3G section). This ensures that the train can obtain information about the adjacent track section in the forward direction, enhancing the safety of the system. However, in the case of reverse operation (from Station A to Station B), the 1G section presents a different signal configuration. Since the train is approaching 1G from another direction at this time, 1G becomes the first block section between the two stations, and it no longer needs the 3G section to provide instruction information. Therefore, the 1G section only relies on the main track signal to work. In the process of Station A switching from the receiving state to the departure state, a short signal adjustment time may occur because the signal system needs to adapt to the new operating state and reconfigure. In this process, after losing the command information provided by other sections (3G), the 1G section needs a period of time (usually 2.3~2.8 seconds) to re-evaluate the current status and reset. At this time, the track relay of the 1G section will be released immediately (stop driving), which usually causes an alarm in the 1G section and a red flashing band will be displayed on the console, that is, "flashing red" indicates that the section is currently in an abnormal working state.

[0062] On the other hand, when during the change process, the receiving direction of Station B is changed to the departure direction (from Station A to Station B, changed to Station B to Station A), the receiver of the 9G section receives and processes the command information of the 11G section, and the command information is sent from Station A to Station B through the 9G small track relay. It takes a certain amount of time to send the small track conditions from Station A to Station B. During this period of time, since there is no command information on 11G, the track relay of 11G will also stop driving and fall, causing the 11G track section to "flash red".

[0063] On the other hand, when Station A is the departure station, the direction of the relay station under the jurisdiction of Station A is consistent with that of Station A. Station A changes from a departure station to a receiving station. When changing direction, if the relay station completes the direction circuit action before this station, the direction of the relay station is the receiving direction, and the direction of Station A is still the departure direction. At this time, 7G no longer receives the command information sent by 5G, that is, 5G cannot receive the command information. Similarly, 7G cannot receive the command information, which will cause 5G and 7G to flash red light bands due to the loss of command information.

[0064] From the above description, it can be seen that when the train is changing direction, different positions may appear "flashing red", and the appearance of "flashing red" will affect the normal execution of the train's changing direction operation. Therefore, in this embodiment, it is first necessary to determine whether a change direction instruction is currently detected. Specifically, since the track is divided into different sections, here, it can be monitored from the signal receiver of the current section to determine whether a change direction instruction is received.

[0065] 102. When the change direction instruction is detected, the state of the current section is determined based on the operating state of the parallel track relays.

[0066] When it is determined that the current signal receiver has indeed received the change direction instruction, it means that the train's direction of travel needs to be changed at this time, so the sequence between the sections is about to change. At this time, it is necessary to determine whether the current section has completed the corresponding operation of the track relay based on the change direction instruction. Therefore, it is necessary to detect and analyze the operating status of the track relay connected in parallel to the change direction control device that deploys the method described in this embodiment. Since the function of the current parallel track relay is to determine the operating status of the current section, by detecting the operating status of the track relay, it can be determined whether the track of the current section has completed the reset and adjustment required for the change direction.

[0067] 103. If it is determined that the state of the current section is an occupied state, a first control instruction is generated and sent to a signal receiver of a target section so as to shield the operating state of the track relay and indicate that the current section is in a non-occupied state.

[0068] The target section is the next section of the current section in the direction of the train after the change of direction.

[0069] When it is determined that the current section state is occupied, it means that the current section has not completed the adjustment and reset required by the change command. If the operating state of the track relay of the current section is sent to the subsequent target section as command information in real time, it is likely that not only the current section will appear "flashing red" because the current track relay fails to receive the command information sent by the previous section, but also the operating state of the track relay of the subsequent target section will be affected, resulting in the target section also being affected. Therefore, in this step, the operating state of the track relay connected in parallel with the current change control device can be shielded, and the instruction "the current section is in a non-occupied state" is sent to the signal receiver of the subsequent target section in the form of the first control instruction. This ensures that when the track of the current section is reset and adjusted, the problem of sending the operating state of the track relay at this time is avoided, so that the section will not appear "flashing red" during the change process, thereby ensuring the smooth progress of the change process.

[0070] This embodiment provides a train redirection control method, which is applied to a redirection control device, and the redirection control device is connected in parallel with the track relay in the small track circuit of the train section. Among them, the present application can detect whether a redirection instruction is received from the signal receiver of the current section, and the redirection instruction is used to modify the running direction of the train; then when the redirection instruction is detected, the state of the current section is determined based on the running state of the parallel track relay; finally, if it is determined that the state of the current section is occupied, a first control instruction is generated and sent to the signal receiver of the target section, so as to shield the running state of the track relay and prompt that the current section is not occupied; wherein, the target section is the next section of the current section in the train's running direction after redirection, thereby realizing the train redirection control function. Compared with the prior art, the present application can shield the operating status of the original track relay by means of a redirection control device connected in parallel with the track relay, thereby ensuring that the first control instruction that can prompt that the current section is in a non-occupied state is sent to the subsequent target section, rather than the operating status of the original track relay. This can ensure that during the redirection process, the situation in which the current section cannot be reset in time and the current section cannot be issued as being in a non-occupied state is avoided. This also avoids the situation in which the current track section cannot be reset in time and the original track relay cannot be energized and "flashes red". This further avoids the smooth implementation of the train redirection process being affected by the "flashing red" situation in the track section, thereby ensuring the smooth execution of the train redirection process. In addition, since the current section can replace the operating status of the track relay in the current section based on the first control instruction, this avoids the situation where the operating information of the track relay in this section cannot be sent out in time in certain cases. It can also be replaced based on the first control instruction, ensuring that the target section can also smoothly perform track detection operations, thereby reducing the "flashing red" phenomenon in subsequent target sections to a certain extent, and further improving the smooth execution of the train change process.

[0071] To explain in more detail below, the present application embodiment provides another train change control method, which is applied to a change control device, wherein the change control device is connected in parallel with a track relay in a small track circuit of a train section; specifically, Figure 3 As shown, the method includes:

[0072] 301. Detect whether a change instruction is received from a signal receiver of the current section.

[0073] The change direction instruction is used to modify the running direction of the train.

[0074] In this embodiment, a signal receiver is provided in each section, and the signal receiver is used to receive instructions or information transmitted based on the upstream position in the direction of train travel, including a change direction instruction, which can be understood as an instruction issued to each section of the train track when the train changes its direction of travel. Since the track status needs to be detected in sequence according to the direction of travel and fed back to the train central control platform in order to ensure safety during train operation, the instruction can trigger the track of each section to perform status self-inspection and feedback.

[0075] 302. Determine whether the resetting operation is completed in the small track circuit of the current section.

[0076] As in the above embodiment Figure 2 From the example, it can be seen that in the process of redirection, each section actually needs the instruction information issued by the previous section to realize the self-check of the track status in each section. In this process, based on the influence of various factors, such as communication conditions, signal equipment response efficiency and other factors, after receiving the redirection instruction, the time required to complete the redirection reset operation in the small track circuit is different. Some may respond faster, while others may respond slower. Therefore, when improving the response process based on the redirection control device described in this embodiment, it is possible to first determine whether the current redirection reset operation is completed. In other words, if the current section responds faster, then the relevant parameters have been adjusted based on the redirection reset operation, and the actual operating status of the track relay can be used to characterize the actual status of the current section. Then there is no need to execute the subsequent steps. Otherwise, it means that the current response is slow and the intervention of the method described in this embodiment is still required.

[0077] Based on this, it can be determined that there are two situations in the judgment result, one is that the current section has not completed the reset operation, and the other is that the reset operation has been completed. Here, when it is determined that the reset operation has not been completed, step 303 is executed; otherwise, when it is determined that the reset operation has been completed, step 307 is executed.

[0078] 303. When the change direction instruction is detected, the state of the current section is determined based on the operating state of the parallel track relays.

[0079] In the case where the aforementioned step also determines whether the redirection reset operation is completed in the small track circuit of the current section, this step "when the redirection instruction is detected, the state of the current section is determined based on the operating state of the parallel track relay" can be executed as follows: if it is determined that the current section has not completed the redirection reset operation, then when the redirection instruction is detected, the state of the current section is determined based on the operating state of the parallel track relay.

[0080] If it is determined that the current section has not completed the re-direction reset operation, it means that the small track circuit corresponding to the current section has not been able to respond quickly to the re-direction instruction, which means that the operating status of the track relay in the current section is still the same as before the re-direction, and the previous section in the original direction needs to send instruction information (the status information of the track relay in the previous section). However, other sections may have completed the re-direction reset operation at this time, so the current section cannot obtain the instruction information, and an alarm will appear and "flashing red". Therefore, when it is determined that the current section has completed the re-direction reset operation, it is necessary to immediately determine the operating status of the current track relay, and use this to determine the status of the section, so as to implement subsequent steps.

[0081] In some embodiments, the operating state of the track relay includes excitation to lift up and deactivation to drop down; the state of the current section also includes a non-occupied state;

[0082] Based on this, in this step, "when the change direction instruction is detected, determining the state of the current section based on the operating state of the parallel track relay" can be specifically performed as follows:

[0083] When the change direction instruction is detected, if it is determined that the running state of the track relay is stopped and dropped, it is determined that the current section is in an occupied state;

[0084] When the change direction instruction is detected, if it is determined that the operating state of the track relay is excitation and attraction, it is determined that the current section is in a non-occupied state.

[0085] In this embodiment, when the track relay is in the state of being energized and attracted, it indicates that the track is normal at this time and trains can pass through, so the section is in a non-occupied state. When the track relay is in the state of being stopped and dropped, it indicates that there is an abnormality in the track and trains cannot pass through, so the section is in an occupied state. In this way, the occupancy state of the section can be analyzed by analyzing whether the track relay is energized, so that the signal condition of the current section can be detected from the relay level, thereby inferring whether the section is occupied. The occupancy state of the section can be detected while using existing equipment or devices, which can save costs.

[0086] 304. If it is determined that the state of the current section is an occupied state, a first control instruction is generated and sent to a signal receiver of a target section so as to shield the operating state of the track relay and indicate that the current section is in a non-occupied state.

[0087] The target section is the next section of the current section in the direction of the train after the change of direction.

[0088] In some embodiments, the control device may specifically be a backup relay, and the backup relay is connected in parallel with the track relay in the small track circuit;

[0089] Based on this, in this step, “if it is determined that the state of the current segment is occupied, then generating a first control instruction and sending it to the signal receiver of the target segment” includes:

[0090] If it is determined that the state of the current section is an occupied state, the operating state of the standby relay is controlled to be excitation-activated, and a first control instruction is generated based on the operating state of the standby relay;

[0091] The first control instruction is sent to a signal receiver of a target section so as to indicate that the current section is in a non-occupied state based on the operating state of the standby relay.

[0092] For the target section, the first instruction information sent by this section can actually be generated by the state of the relay. In this case, the control device can be specifically another relay, that is, the spare relay, and then the corresponding instruction information is generated by controlling the spare relay to perform excitation and suction and stop driving and fall. Of course, in this embodiment, in order to save the recognition of the first instruction by other sections, the operating state of the spare relay can be controlled to be excitation and suction, replacing the track relay that stops driving and falls due to the failure to obtain the instruction information of the previous section. In this way, the first control instruction received by the signal receiver of other sections is actually the excitation and suction signal sent by the spare relay. This not only ensures that the current section can output the "non-occupied state" instruction, but also saves the process of other sections identifying and parsing the instruction, thereby simplifying the control process of this embodiment and improving the efficiency of the entire process.

[0093] 305. After sending the first control instruction, detect whether the resetting operation is completed in the small track circuit of the current section.

[0094] Based on the description of the above steps, it can be seen that since the time required for the reset operation is not actually long, after the reset is completed, the small track circuit at this time no longer needs the instruction information of the original "upstream" section as before the reset, and the track relay in the small track circuit of the section can operate normally, so there is no need to continue to use the reset control device described in this embodiment to send the first control instruction instead. Therefore, after sending the first operation execution, it is possible to detect whether the reset operation is completed in the small track circuit of the current section.

[0095] 306. When it is determined that the reset operation is completed, generate a second control instruction to stop shielding the operating state of the track relay, and send the operating state of the track relay to the signal receiver of the target section.

[0096] When it is found that the reset operation has been completed in the current small track circuit, it means that the small track circuit in the current section is normal. Then the state represented by the track relay is the actual state of the current section, and it is no longer affected by the "flashing red". At this time, there is no need to judge the operating state of the track relay. Therefore, the shielding behavior of the previous first control instruction can be terminated by issuing the second control instruction, so that the current section can continue to send the operating state of the track relay at this time to the receiver of the target section. In this way, it is ensured that when the operating state of the track relay does not need to be shielded, the effect of restoring its sending operating state is restored.

[0097] 307. If it is determined that the current section has completed the resetting operation, when the resetting instruction is detected, the operating status of the track relay is sent to the signal receiver of the target section.

[0098] Based on the judgment of the aforementioned step 302, it can be known that when it is determined that the current section has completed the resetting operation, it means that the small track circuit has been reset at this time, and the operating status of the track relay at this time is not affected by the "flashing red", but can truly reflect the operating status of the track in the current section. In this case, the operating status of the track relay can be directly sent to the target section. This avoids the situation where the operating status of the track relay that can normally characterize the operating status of the track can be output normally after the small track circuit of the current section has been reset based on the resetting instruction. If the operating status of the track relay at this time reflects that the current section is occupied, it means that there is indeed an abnormality in the track of the section at this time. This ensures that the track detection can be carried out normally, thereby improving the safety of train operation.

[0101] Furthermore, as a response to the above Figure 1 and Figure 3In order to realize the method shown in the figure, another embodiment of the present application also provides a train reversal control device. The train reversal control device embodiment corresponds to the aforementioned method embodiment. For ease of reading, the train reversal control device embodiment will not repeat the details of the aforementioned method embodiment one by one, but it should be clear that the system in this embodiment can correspond to all the contents of the aforementioned method embodiment. Specifically, Figure 4 As shown, the device is applied to a direction control device, and the direction control device is connected in parallel with a track relay in a small track circuit of a train section. The direction control device of the train includes:

[0102] A first detection unit 41 may be used to detect whether a direction change instruction is received from a signal receiver in the current section, wherein the direction change instruction may be used to modify the running direction of the train;

[0103] The first determining unit 42 may be used to determine the state of the current section based on the operating state of the parallel track relay when the first detecting unit 41 detects the change direction instruction;

[0104] The first execution unit 43 can be used to generate a first control instruction and send it to the signal receiver of the target section if the first determination unit 42 determines that the state of the current section is occupied, so as to shield the operating state of the track relay and prompt that the current section is not occupied; wherein the target section is the next section of the current section in the direction of train travel after the change of direction.

[0105] Further, such as Figure 5 As shown, the device also includes:

[0106] A second determining unit 44 may be used to determine whether a resetting operation is completed in the small track circuit of the current section, wherein the resetting operation may be used to initialize the small track circuit to which the track relay belongs based on the resetting instruction to adapt to the resetting instruction;

[0107] The first determination unit 42 can be specifically used to determine the state of the current section based on the operating state of the parallel track relay when the resetting instruction is detected if the second determination unit 44 determines that the current section has not completed the resetting operation.

[0108] Further, such as Figure 5 As shown, the operating state of the track relay includes excitation to pick up and stop driving to drop; the state of the current section also includes a non-occupied state;

[0109] The first determination unit 42 can also be used to, when the change direction instruction is detected, if it is determined that the operating state of the track relay is stopped and dropped, determine that the current section is in an occupied state; and, when the change direction instruction is detected, if it is determined that the operating state of the track relay is excited and lifted, determine that the current section is in a non-occupied state.

[0110] Further, such as Figure 5 As shown, the device also includes:

[0111] The second execution unit 45 can be used to send the operating status of the track relay to the signal receiver of the target section when the second determination unit 44 determines that the current section has completed the resetting operation and the resetting instruction is detected.

[0112] Further, such as Figure 5 As shown, the device also includes:

[0113] The second detection unit 46 may be used to detect whether the resetting operation is completed in the small track circuit of the current section after the first execution unit 43 sends the first control instruction;

[0114] The third execution unit 47 can be used to generate a second control instruction to stop shielding the operating state of the track relay and send the operating state of the track relay to the signal receiver of the target section when the second detection unit 46 determines that the reset operation is completed.

[0115] Further, such as Figure 5 As shown, the modified control device includes a backup relay, and the backup relay is connected in parallel with the track relay in the small track circuit;

[0116] The first execution unit 43 can be specifically used to control the operating state of the standby relay to be excitation-activated if it is determined that the state of the current section is an occupied state, and generate a first control instruction based on the operating state of the standby relay; and send the first control instruction to the signal receiver of the target section, so as to prompt that the current section is in a non-occupied state based on the operating state of the standby relay.

[0117] In order to achieve the above-mentioned purpose, according to another aspect of the present application, an embodiment of the present application further provides a train change control device, the device comprising:

[0118] control terminals and backup relays;

[0119] Among them, the standby relay is connected in parallel with the track relay in the small track circuit; the control terminal is used to collect direction instructions from the signal receiver, and output control instructions to control the operating state of the standby relay.

[0120] The embodiments of the present application provide a method, device and equipment for controlling the direction of a train change. In the embodiments of the present application, it is possible to detect whether a direction change instruction is received from a signal receiver of the current section, wherein the direction change instruction is used to modify the direction of the train. Then, when the direction change instruction is detected, the state of the current section is determined based on the operating state of the parallel track relay. Finally, if it is determined that the state of the current section is occupied, a first control instruction is generated and sent to the signal receiver of the target section to shield the operating state of the track relay and indicate that the current section is not occupied. The target section is the next section of the current section in the direction of travel of the train after the direction change, thereby realizing the function of controlling the direction of the train change. Compared with the prior art, the present application can shield the operating status of the original track relay by means of a redirection control device connected in parallel with the track relay, thereby ensuring that the first control instruction that can prompt that the current section is in a non-occupied state is sent to the subsequent target section, rather than the operating status of the original track relay. This can ensure that during the redirection process, the situation in which the current section cannot be reset in time and the current section cannot be issued as being in a non-occupied state is avoided. This also avoids the situation in which the current track section cannot be reset in time and the original track relay cannot be energized and "flashes red". This further avoids the smooth implementation of the train redirection process being affected by the "flashing red" situation in the track section, thereby ensuring the smooth execution of the train redirection process. In addition, since the current section can replace the operating status of the track relay in the current section based on the first control instruction, this avoids the situation where the operating information of the track relay in this section cannot be sent out in time in certain cases. It can also be replaced based on the first control instruction, ensuring that the target section can also smoothly perform track detection operations, thereby reducing the "flashing red" phenomenon in subsequent target sections to a certain extent, and further improving the smooth execution of the train change process.
