Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is obvious that the described embodiments are some, but not all embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
The problem that the normal operation of the main line is influenced by using an in-garage dynamic testing scheme commonly exists when the existing FAO train is awakened in a garage and then goes to the main line to be avoided or is dynamically tested on a parking line. The following describes a switch control method based on FAO train dynamic test according to the present invention with reference to fig. 1 to 5. Fig. 1 is a schematic flow chart of a method for controlling a switch under a train dynamic test based on an FAO according to the present invention, as shown in fig. 1, the method includes:
and step 110, controlling track locking equipment to lock the test jump section by the train vehicle-mounted controller VOBC on the main line based on the dynamic test content to be carried out by the train to be tested.
Optionally, an execution main body of the switch control method under the FAO-based train dynamic test provided by the present invention is a vehicle-mounted controller VOBC of the train to be tested, and the description is given here for the train dynamic test under the FAO mode: in a full-automatic driving FAO signal system, a train is dormant in a garage, a running comprehensive automation system TIAS controls to perform automatic power-on awakening operation, specifically, the TIAS sends an awakening operation instruction and a power-on instruction to a vehicle-mounted controller VOBC of the train to be tested, the VOBC of the train to be tested performs power-on starting on the train to be tested after receiving the awakening operation instruction and the power-on instruction, the awakening operation instruction further triggers a static test and a dynamic test before the train to be tested runs, the static test and the dynamic test are test flows preset in the VOBC of the train to be tested, wherein the static test is a test of vehicle-mounted equipment under the condition that the train does not need to generate displacement, the dynamic test is a test of a train traction system and a brake system, the train needs to perform running test within a certain jump range, and because in an FAO mode, there is no manual operation by the driver. Fig. 2 is an illustration of a parking line scene provided by the present invention, and fig. 3 is an illustration of a line scene to be avoided provided by the present invention, as shown in fig. 2 and fig. 3, a train is in a parking line or a line to be avoided dormant state, when needing to be put into operation, the train needs to be dynamically tested, when a test range covers a parking line or a line turnout to be avoided, if the double-acting turnout is in a reverse position at this time, normal passing of the train on the main line is affected, and the operation is seriously affected; specifically, the train needs to automatically perform static test and dynamic test, and when the train comes out of the garage and enters a to-be-avoided line or a storage line on a main line for dynamic test, a front-back jump range of the train to be tested in the dynamic test process conflicts with other trains normally running on the main line, so that accidents of forcing to stop the other trains or suspending the current dynamic test to avoid, and the like, which increase time cost and labor cost, may occur. Therefore, according to the switch control method under the train dynamic test based on the FAO provided by the invention, after a train to be tested, which needs to be dynamically tested on a to-be-avoided line or a storage line of a main line, receives a wake-up operation instruction sent by the TIAS, a front-back jump range which needs to be occupied on the main line in the dynamic test process is firstly locked according to the to-be-performed dynamic test content, namely, the VOBC controls the track locking device to lock the test jump section based on the to-be-performed dynamic test content, wherein the test jump section is the main line section corresponding to the front-back jump range when the train is tested on the main line according to the dynamic test content. The track locking device is described here, which may be one device or multiple devices, and when the track locking device is one device, it is an interlocking CI, and by establishing direct communication between the onboard VOBC and the track interlocking CI, the VOBC directly issues a locking instruction to the interlocking CI to trigger the interlocking CI to lock the test skip section (specifically, lock the corresponding axle counting section), where the determination of the test skip section and the corresponding axle counting section is determined by the onboard VOBC itself based on dynamic test content, and then directly constructs a locking command based on the corresponding axle counting section and issues the locking command to the interlocking CI; the track locking device may also be a plurality of devices, including, for example, Zone Controllers (ZCs) and interlocking CIs, the VOBC firstly sends dynamic test content to the ZC, the ZC determines a positive line section needing to be locked according to the dynamic test content and converts the positive line section into a counting shaft area needing to be locked, the ZC then sends a locking instruction of the axle counting region to the interlock CI to trigger the interlock CI to lock the axle counting region, therefore, the track locking device is not defined here, nor is the execution body for determining the test jump section based on the dynamic test content defined, the execution subject of the test jump section determination is different for different track locking devices, and the calculation amount of the test jump section determination is constant, but the target of sharing the constant calculation amount is not the same.
And step 120, after the VOBC confirms that the test jump section is successfully locked, controlling the train to be tested to start the dynamic test.
Optionally, the VOBC controlling the track locking device to lock the test jump section also requires a step of feedback confirmation, so that step 120 provides that the dynamic test of the train to be tested is started only after the VOBC confirms that the test jump section is successfully locked. Here, it is described that the test skip section is successfully locked, and since the track lock device is not specifically limited, the process of confirming that the test skip section is successfully locked cannot be fixed, for example, if the track lock device is only a track interlock CI, the track interlock CI returns the lock state of the counter shaft section after the lock operation is performed to the VOBC after the VOBC directly issues the lock instruction to the interlock CI, and the VOBC is further required to compare the lock state with the test skip section stored in the VOBC itself to confirm whether the test skip section is successfully locked; if the track locking device comprises a zone controller CI and a track interlock CI, the track interlock CI returns the locking state of the corresponding axle counting section to the ZC after executing the locking operation corresponding to a locking instruction which is issued by the ZC to the interlock CI and comprises a locking axle counting region, if the locking state is checked by the ZC and the locking axle counting region is consistent, the VOBC returns the permission test jump authorization, if the VOBC can receive the permission test jump authorization returned by the ZC, the dynamic test is started successfully by confirming the locking of the test jump section, if the VOBC cannot receive the permission test jump authorization returned by the ZC, the dynamic test is continuously waited until the operation in the step 110 is executed again after exceeding the preset time length, the operation is circulated until the VOBC receives the permission test jump authorization returned by the ZC, and if the circulation number is exceeded, the dynamic test fault alarm is sent out, therefore, the specific implementation of the test skip segment lock is not particularly limited.
According to the method provided by the invention, through a train vehicle-mounted controller VOBC to be tested on a main line, based on the dynamic test content to be carried out by the train to be tested, a track locking device is controlled to lock a test jump section; and after the VOBC confirms that the test jump section is successfully locked, controlling the train to be tested to start the dynamic test. The train is dynamically tested in a full-automatic driving mode, so the test content can be provided for the vehicle-mounted VOBC in advance, the vehicle-mounted VOBC controls the locking equipment on the track to lock the corresponding section to be occupied by jumping back and forth through the section to be occupied by the train in the test content, and the problem that two vehicles collide or other safety problems are caused by the fact that the vehicles normally running on the main line break into the test area is avoided. The VOBC can block the main line section to be occupied according to the content of the dynamic test before the dynamic test is carried out, so that the dynamic test can be carried out smoothly, and accidents caused by other trains running on the main line breaking into the section can be avoided. Therefore, the method provided by the invention realizes that the line conflict does not occur between the dynamic testing scheme in the garage line and the normal operation of the main line when the FAO train is awakened in the garage and then dynamically tested on the main line to be avoided or the parking line.
Based on the above-described embodiments, in this method,
after the train to be tested completes the dynamic test,
the VOBC controls the track lock device to cancel the test jump section.
Optionally, after the VOBC controls the train to be tested to complete the dynamic test, the track section corresponding to the test jump range of the main track is required to be released, so that long-time influence on normal operation of the main track caused by occupying the test jump section for too long time can be avoided. As described above, since the track lock device is not specifically limited, when the track lock device is only one track interlock CI, the VOBC directly issues a command to unlock the corresponding axle counting section to the track interlock CI, and after the track interlock CI completes unlocking, the VOBC returns the unlocked state to the VOBC, so that the VOBC can confirm whether the release of the track section corresponding to the test jump range is completed; when the track locking equipment comprises a zone controller ZC and a track interlock CI, the VOBC issues a test jump section canceling command to the ZC, and the ZC sends a lock canceling command to the CI based on the received test jump section canceling command to trigger the CI to unlock a section of jump lock and then returns a state that the corresponding physical section is not jump locked and is released to the ZC, so that the whole control flow is completed; therefore, there are many cases where the flow of the VOBC controlling the track lock device to cancel the test jump section is not particularly limited herein.
Based on the above embodiment, in the method, the controlling, by the vehicle-mounted controller VOBC of the train to be tested on the main line, the track locking device to lock the test skip section based on the upcoming dynamic test content of the train to be tested includes:
the method comprises the steps that a vehicle-mounted controller VOBC of a train to be tested on a main line sends a main line application test request to track locking equipment, wherein the main line application test request comprises upcoming dynamic test contents of the train to be tested;
correspondingly, after the VOBC confirms that the test jump section is successfully locked, controlling the train to be tested to start the dynamic test, including:
if the VOBC receives a test permission authorization response returned by the track locking equipment, controlling the train to be tested to start the dynamic test, wherein the test permission authorization response is generated after the track locking equipment confirms that a test jump section corresponding to the dynamic test content is in a locked state;
correspondingly, the VOBC controlling the track locking device to cancel the test jump section includes:
the VOBC cancels a positive line test request to the track locking device to trigger the track locking device to unlock the test jump section.
Optionally, a control manner of the VOBC is specifically defined, that is, the VOBC needs to complete control of locking the test skip section by interacting with the track locking device for a request response type data packet, instead of directly issuing a control signal, the VOBC sends an application positive line test request, the track locking device that is used as a receiving party needs to analyze the application positive line test request and extract a dynamic test content to be performed by the train to be tested, then determines an axle counting region that needs to be locked according to the dynamic test content, and then performs a locking operation of the axle counting region, and a manner in which the VOBC confirms that the test skip section is successfully locked is also based on whether an allowable test authorization response returned by the track locking device is received, and if the allowable test authorization response returned by the track locking device can be received, confirms that the test skip section is successfully locked, otherwise, the actual work of confirming whether the locking of the test jump section is successful is completed at the track locking device, correspondingly, the VOBC controlling the track locking device to cancel the test jump section is also completed by sending a cancel main track test request to the track locking device, therefore, the track locking device is only a track interlocking CI which can process simple instructions and does not process complex logic calculation units, the track locking device should be composed of two parts, the part which finally receives simple operation instructions to execute locking operation is the track interlocking CI, the other part B is used as an intermediate part to bridge the communication between the VOBC and the track interlocking CI, the part B is provided with a process complex logic calculation unit for analyzing requests, calculating and converting instructions, specifically, the part B analyzes and converts the main track test request sent by the VOBC into a control instruction to be sent to the interlocking CI, the component B also receives the physical section locking state information returned by the interlocking CI, compares the physical section locking state information with the required test jumping section locking, if the physical section locking state information is consistent with the required test jumping section locking state information, confirming that said test skip segment lock is successful, constructing a permission test grant response to be sent to said VOBC, correspondingly, the component B also receives a positive line canceling test request sent by the VOBC, then analyzes a corresponding release section in the positive line canceling test request, constructs a release instruction based on the release section and sends the release instruction to the interlocking CI to trigger the CI to unlock and skip the locking operation of the corresponding physical section, and returns the non-skip locking state of the corresponding physical section to the component B after the interlocking CI is unlocked, all the control and confirmation steps are that the component B undertakes the analysis request or responds to the extraction target message to convert the message into the instruction and then sends the converted message to the interlocking CI in the form of a simple instruction; in the Train track system, the component B is a communication middleware with a computing function in the Train track system, and may be, for example, a zone controller ZC or a ground Train Intelligent monitoring system (ITS), which is not particularly limited herein.
Based on the above embodiment, in the method, the transmitting, by the vehicle-mounted controller VOBC of the train to be tested on the main track, a request for applying the main track test to the track locking device, where the request for applying the main track test includes the content of the dynamic test to be performed by the train to be tested, includes:
a VOBC (vehicle-mounted controller) of a train to be tested on a main line sends a request for applying jump authorization to a zone controller ZC so as to trigger the ZC to send a jump locking request to a track interlock CI based on the request for applying jump authorization;
the method comprises the steps that a ZC determines an application locking axle counting area based on dynamic test contents to be carried out by a train to be tested carried in an application jumping authorization request, and a jumping locking request is constructed in the application locking axle counting area, wherein the jumping locking request is used for triggering a turnout corresponding to the CI locking and returning to a jumping locking state to the ZC after the locking is successful;
correspondingly, if the VOBC receives a test permission authorization response returned by the track locking device, the VOBC controls the train to be tested to start the dynamic test, wherein the test permission authorization response is generated after the track locking device confirms that the test jump section corresponding to the dynamic test content is in a locked state, and includes:
if the VOBC receives a jump authorization response returned by the ZC, controlling the train to be tested to start the dynamic test, wherein the jump authorization response is issued to the VOBC after the ZC confirms that the jump locking state returned by the CI is received by the ZC and conforms to the dynamic test content to be performed;
correspondingly, the VOBC canceling the positive line test request to the track locking device to trigger the track locking device to unlock the test skip section includes:
and the VOBC sends a positive line cancellation test request to the ZC to trigger the ZC to send a jump unlocking request to the CI based on the curve positive line request, wherein the jump unlocking request is used for triggering the ZC to return to the unlocked state of the test jump section after the CI completes unlocking the test jump section.
Optionally, the embodiment further defines that the track locking device includes a zone controller ZC and a track interlock CI, and the vehicle-mounted VOBC indirectly controls the CI to lock the axle counting section of the test jump section through sequential communication among the vehicle-mounted VOBC, the zone controller ZC and the interlock CI. The zone controller ZC and the interlocking CI are used as track locking equipment, so that the track locking equipment is more compact, and the communication real-time performance is higher, because the zone controller ZC and the interlocking CI are closer in physical position compared with the distance between the ground train intelligent monitoring system ITS and the interlocking CI when the ground train intelligent monitoring system ITS and the interlocking CI are used as the track locking equipment.

And after receiving the application, the interlock checks the turnout action condition and the section locking condition, drives and locks the turnout, sends the jump locking state of the physical section to the ZC after the locking is successful, and sends the permission jump authorization to the VOBC after the ZC receives the jump locking state. After the VOBC completes the dynamic test, the ZC sends a request for canceling the jump locking to the CI, and after the CI unlocks the jump-locked section, the ZC sends the non-jump-locked state of the physical section to complete the whole control flow.
Based on the above embodiment, in the method, the determining, by the ZC, an application lock axle counting area based on the content of the dynamic test to be performed by the train to be tested, which is carried in the request for applying the jump authorization, includes:

After receiving the dynamic test request of the VOBC, the ZC needs to check whether the following 4 conditions are simultaneously satisfied:
1. the front and rear axle counters of the train are all idle (if the adjacent axle counters are end lines, the idle state does not need to be judged);
2. the SPKS switch is OFF;
3. full line emergency braking commands are not implemented;
4. no train outside the pre-jump lock axle counting section or train MA has not entered or crossed the pre-jump lock axle counting section.
When the above 4 conditions are simultaneously satisfied, the ZC applies for a jump lock to the CI, and the lock section is a pre-jump axle counting section.
Based on the above embodiment, in the method, the CI, based on the switch corresponding to the lock application axle counting area lock carried in the skip lock request, includes:
the CI judges whether a second section locking condition is met or not based on an application locking axle counting area carried in the jump locking request;
if the condition is met, the corresponding turnout is locked.
Optionally, this embodiment further provides that the CI performs other checks besides the control instruction sent by the ZC to ensure the efficiency of the locking operation. The CI determines whether the current state satisfies the "jump locking condition", and needs to check whether the following 8 conditions are satisfied at the same time:
1. is not locked by an access and is not locked by protection;
2. SPKS is not set;
3. the infringement zone of the zone is unoccupied and not blocked;
4. the access path where the section is located is not closed;
5. if the section comprises the flood-proof door, the flood-proof door needs to be closed;
6. the position of the turnout is effective, and the turnout does not act;
7. the turnout is not blocked and the turnout is not guided to be locked;
8. the current position of the turnout is consistent with the turnout position specified by the axle counting section.
Wherein, CI calculates the switch and its stipulated position that include in the district section according to the axle counting district section, when judging that the switch is not in the stipulated position at present in the axle counting district section, need to judge whether the switch can be pulled to the stipulated position, need to check switch "can act the condition" and include following 3 at this moment:
1. the turnout is not quarto and is extruded;
2. the turnout section is not locked and is not locked in a jumping way;
3. the switch segment is unoccupied.

acquiring the current state type of the locking and axle counting application area, and judging whether the locking condition of the second section is met or not based on the current state type;
the current state types are a shaft counting section jumping idle state, a shaft counting section jumping row selection state and a shaft counting section jumping locking state.
Optionally, when the CI determines whether the lock condition of the second segment is satisfied based on the lock application axle counting area carried in the skip lock request, it needs to obtain the state type of the lock application axle counting area at the current time, where the state is updated in the CI in real time and is identified by the corresponding concise number. FIG. 5 is a diagram illustrating the definition of the current status type of the lock counting area provided by the present invention, as shown in FIG. 5:
state 0: the axle counting section jumps to an idle state;
state 1: a shaft counting section jumping and row selecting state;
state 2: a meter shaft section skip lock state.
0-0: when all the axle counting sections of the physical section to which the current axle counting section belongs are in a jumping idle state, setting the physical section as non-jumping locking and keeping a state 0;
0-1: if the current axle counting section receives a jump locking application and the corresponding physical section is not explicated, setting explication and switching to a state 1, otherwise keeping the state 0;
1-1: checking whether the current axle counting section meets a 'jump locking condition', if the current axle counting section does not meet the condition 8, continuously checking that the axle counting section contains 'movable operation conditions' of the turnout, if the current axle counting section meets the condition, driving the turnout to a specified position, and keeping the state 1;
1-2: checking whether the current axle counting section meets a jump locking condition, if so, clearing the explication of the physical section and transferring to a state 2;
1-0: checking whether the current axle counting section meets a jumping locking condition, if the current axle counting section does not meet the conditions 1-7, or meets the conditions 1-7 but does not meet a turnout movable operation condition, or drives the turnout to exceed the maximum time limit, clearing the physical section commander and switching to a state 0;
2-2: continuously checking whether the current axle counting section meets a 'jump locking condition', if the condition is met, setting a jump locking state of a physical section to which the axle counting section belongs, sending the jump locking state of the physical section to a ZC, and keeping a state 2;
2-0: if the current axle counting section receives the application of canceling the jump locking, unlocking the jump locking state of the physical section to which the axle counting section belongs, and turning to a state 0; if the application for canceling the jump locking is not received, but the communication between the CI and the ZC is interrupted, the jump locking of the physical section adopts a delayed unlocking mode, the jump locking is switched to a state 0 after unlocking, and the communication is recovered to be normal during the delay, and then the jump locking is kept in a state 2.
The purpose of communication interruption delayed unlocking is that the jump locking section can be unlocked automatically when communication is in fault, and normal operation of other trains is not influenced. And the unlocking time limit calculation mode is that the worst delay time of the communication between the CI and the ZC, the worst delay time of the communication between the ZC and the VOBC, the emergency braking reaction time of the train and the stopping time of the train after the emergency braking is output are accumulated, and the unlocking time limit is not less than the accumulated value.
