Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present invention more apparent, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are some embodiments of the present invention, but not all embodiments of the present invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Fig. 1 is a flowchart of a control method for train operation according to an embodiment of the present invention, as shown in fig. 1, applied to a zone controller ZC, where the method includes:
s1, if an unfiltered train exists and a screening execution command sent by an ATS center of an automatic train monitoring system is received, judging whether a preset train safety condition is met.
The execution body of the embodiment of the invention is an electronic device, and in particular, the electronic device of the embodiment of the invention can be an area controller. Wherein the ZC may communicate with an automatic train monitoring system (ATS center, automatic Train Supervision) center.
The non-screened train refers to a train which is not subjected to screening operation of the head screen and the tail screen, and also refers to a train which is not subjected to screening operation of any one of the head screen and the tail screen; the ATS center may be manipulated by a dispatcher to issue a screening execution command to the ZC.
S2, when the preset train safety condition is met, train screening operation is carried out on the non-screened trains, and mobile authorization is initiated.
Specifically, if the ZC in this embodiment timely finds that there is a train that has not undergone screening, i.e. an unfiltered train, on the current line, and meanwhile, if a screening execution command sent by the ATS center side is also received, and meanwhile, if the second train condition also meets a preset train safety condition, a train screening action can be initiated, and a movement authorization is initiated, so that not only is the operation efficiency improved, but also the driving safety of the train is ensured.
Wherein the preset train safety condition is actually a preset train safety working condition.
For example, the preset train safety conditions include that the safety envelope of the VOBC corresponding to the train is within the jurisdiction of the ZC, etc., which are only examples and not limiting.
For example, if the preset train safety condition is met, the safety envelope of the VOBC corresponding to the train is characterized as being in the jurisdiction of the ZC; and if the preset train safety condition is not met, the safety envelope of the VOBC corresponding to the train is characterized as not being in the jurisdiction of the ZC.
In addition, the embodiment of the invention is also suitable for a full-automatic unmanned (FAO, fully Automatic Operation) system without a driver.
For the FAO system, no driver participates in the running process of the train, and the condition that the train cannot normally finish screening possibly exists due to natural, artificial or unexpected reasons, and the ZC cannot normally send train movement authorization, so that the normal operation of the unmanned system is influenced. Obviously, embodiments of the present invention may also overcome this drawback.
Therefore, the embodiment of the invention not only can be used in the FAO system, but also can be applied to a general CBTC system with the participation of a driver as double insurance, and has universality.
The train operation control method provided by the embodiment of the invention is applied to the zone controller ZC, and if the non-screened train exists and a screening execution command sent by an ATS center of an automatic train monitoring system is received, whether a preset train safety condition is met is judged; and when the preset train safety condition is met, carrying out train screening operation on the non-screened train, and initiating mobile authorization. Therefore, the ZC in the embodiment of the invention can timely find the train which is not subjected to screening on the current line, meanwhile, if a screening execution command sent by the ATS center side is received, and meanwhile, if the current condition also meets the preset train safety condition, the train screening action can be initiated, and the movement authorization is initiated, so that the operation efficiency is improved, the running safety of the train is ensured, and the technical problem that the train operation efficiency and the running safety are difficult to be simultaneously considered is solved.
Fig. 2 is a flowchart of a control method for train operation according to another embodiment of the present invention, which is based on the embodiment shown in fig. 1.
In this embodiment, one type of implementation scenario may be specifically discussed as follows.
Specifically, the ZC in this embodiment may find out that the train that has not undergone screening on the current line is an unfiltered train in time, and the ZC may report the unfiltered train to the ATS center side; after the manual confirmation by the staff at the ATS center side, a screening execution command will be issued.
On the basis of receiving the screening execution command, if certain conditions are met at the same time, for example, preset train safety conditions are met, the ZC can complete train screening behaviors on the current line, and then mobile authorization is sent. Therefore, the operation of the unmanned system can be recovered in time, the operation efficiency is improved, and the driving safety of the train is also ensured.
It can be seen that the embodiment of the invention provides a train operation control method capable of manually triggering in-situ screening, mainly considering the condition that the ZC cannot normally perform train screening under partial conditions, and can be manually detected to further ensure safety, so that train screening and mobile authorization sending can be timely completed.
On the basis of the foregoing embodiment, preferably, before S1, the method for controlling train operation further includes:
and S101, transmitting a train set to an ATS center based on a preset period so as to receive a verification command corresponding to the first train fed back by the ATS center.
Specifically, the ZC may periodically send a train list, i.e., a train set, to the ATS center, where the train list may include trains whose train positions fall within jurisdictions corresponding to the ZCs, and the trains are trains to be manually triggered for in-situ screening operations.
Wherein the preset period may be 0.1 seconds apart, which is only exemplary.
Further, it may be further configured that the ZC can receive a verification command of manual in-place screening of the train issued by the ATS center only after the ZC transmits the train list to the ATS center.
Otherwise, the verification command may be considered to fail to execute and the execution result may be fed back to the ATS center.
S102, judging whether the train set comprises the first train or not.
And S103, if the first train is included, feeding back verification success information to the ATS center.
The train set is a set of trains to be screened in a jurisdiction range corresponding to the ZC.
Specifically, if the verification command corresponds to the train a, if the train set includes the train a, the train a is characterized as the train to be screened, and is also the non-screened train, and the train a can be subjected to train screening operation subsequently, and movement authorization is initiated.
On the basis of the foregoing embodiment, preferably, if there is an unfiltered train and a screening execution command sent by an ATS center of an automatic train monitoring system is received, before judging whether a preset train safety condition is met, the control method for train operation further includes:
if train position information sent by the vehicle-mounted controller VOBC corresponding to the second train is received, judging whether preset train safety conditions are met or not;
and when the preset train safety condition is met, sending a field screening request to the VOBC so as to carry out screening operation on the train end field.
Wherein, different from the ATS center and ZC of ground setting, the vehicle-mounted controllers (VOBC, vehicle On Board Controller) are arranged on the train.
Specifically, if the ZC receives the train position information sent by the VOBC on the train, the train position information characterizes the real-time position where the second train is located, and if the preset train safety condition is met, the ZC may send a field screening request to the VOBC.
The on-site screening request can enable an enabling indicator lamp corresponding to the on-site screening behavior of the representation on-site on-train to be turned on; after enabling, a driver on the train may take a corresponding on-site screening button on site to perform a train screening operation on the second train and initiate movement authorization.
It can be seen that the train screening operation can be actively triggered not only by the dispatcher on the ATS center side but also by the driver on the VOBC side.
The second train may or may not be the same train as the first train described above, and is not limited thereto.
On the basis of the foregoing embodiment, preferably, when the preset train safety condition is satisfied, performing a train screening operation on the non-screened train, and after initiating a movement authorization, the control method for train operation further includes:
detecting whether the current moment falls within preset configuration timing;
and if the preset configuration timing is exceeded, feeding back a screening execution confirmation command to the ATS center.
Specifically, the ZC can be ensured to complete logic processing within a certain configuration time; after the configuration time is exceeded, namely the preset configuration time, the execution result is automatically fed back to the ATS center to represent whether the ZC successfully completes the screening operation.
The train safety conditions comprise that the safety envelope of the VOBC corresponding to the train is in the jurisdiction of the ZC, the safety envelope of the VOBC is in a preset section, the screening state corresponding to the VOBC is in an invalid state, the occupation state of the adjacent counting shaft of the counting shaft where the train corresponding to the VOBC is located is in an idle state, other trains except the train corresponding to the VOBC are in a state of being incapable of entering, and the train corresponding to the VOBC is in a stop state.
Wherein the VOBC is disposed on a train, which is broadly referred to as the above mentioned train, which may be an unfiltered train.
Specifically, in condition one, the security envelope of the VOBC is completely within the jurisdiction of the ZC;
the second condition is that the safety envelope of the VOBC is completely located on a preset section, and the preset section comprises a section in a garage of the vehicle section or a section with special configuration;
a third condition is that the head screen state or the tail screen state corresponding to the VOBC is an invalid state;
if the adjacent axle counting exists in the axle counting position of the train corresponding to the VOBC, the occupied state of the adjacent axle counting is an idle state;
if the adjacent axle counting exists in the axle counting positions of the trains corresponding to the VOBC, other trains except the trains corresponding to the VOBC are in a state of being unable to enter, namely, the possibility that no other communication trains enter can be judged based on the train position information of the trains corresponding to the VOBC;
and in the condition six, the train corresponding to the VOBC is in a stopped state, namely, the train is stopped.
It can be seen that if the preset train safety conditions are satisfied, it is considered that the conditions for manually triggering the in-situ screening are already present.
Further, more specifically, with respect to condition one, the security envelope of the VOBC will be all within the jurisdiction of the present ZC, and if some are not within the jurisdiction of the present ZC, the condition of manual in-place screening may be considered not to be satisfied for security.
In the second condition, the section in the garage is a section in the garage of the automated vehicle section, specifically a track section or axle counting section from which the departure garage departs.
In terms of condition three, the invalid state refers to a state without head-to-tail screening.
In terms of condition four, if the train is already at the end of the line, there is no adjacent axle counting, and the situation of the adjacent axle counting may not be considered.
If the adjacent metering axis is in the jurisdiction of other ZCs, namely is not in the jurisdiction of the ZC, the manual in-situ screening function is not performed. This is to consider that there is a delay in the transmission of the neighboring ZCs, so that manual in-place screening functions are not allowed at the boundaries of the neighboring ZCs for security.
Further, in the CBTC system, the purpose of normal train screening is to detect that non-CBTC trains and CBTC trains are not present in the same section, as far as the specific scenario of the manual in-place screening function is concerned.
For example, when a train reports a location to a ZC, the ZC will screen the train. When the distance between the external position of the train and the front axle counting point is smaller than the minimum train length and the front axle counting section is not occupied, the ZC will clear the assumed train in front; when the distance between the external position of the train and the front axle counting section is greater than or equal to the minimum train length and the front axle counting section is occupied, the ZC will reserve the assumed train in front.
Unlike the above, the manual in-situ screening function provided by the embodiment of the invention can ensure safety and can rapidly finish train screening when conditions are met.
For example, when the distance between the external position of the train and the front axle counting point is equal to or greater than the minimum train length, the ZC will clear the assumed train in front when the rear front axle counting section is not occupied after the confirmation of manual detection. Therefore, train screening can be completed rapidly, the operation efficiency is improved, and the driving safety is ensured.
Fig. 3 is a flowchart of a control method for train operation according to still another embodiment of the present invention.
In this embodiment, the method is applied to an ATS center, and includes:
s3, acquiring a screening execution command;
and S4, sending the screening execution command to the ZC so that if the ZC detects that an unfiltered train exists and receives the screening execution command, judging whether a preset train safety condition is met, and when the preset train safety condition is met, carrying out train screening operation on the unfiltered train and initiating movement authorization.
The execution body of the embodiment of the invention is an electronic device, and in particular, the electronic device of the embodiment of the invention can be an ATS center. Wherein the ZC can communicate with the ATS center.
Specifically, the ATS center may send a screening execution command to the ZC side to trigger a subsequent train screening operation, movement authorization.
The train running control method provided by the embodiment of the invention is applied to an ATS center, firstly, a screening execution command is acquired, then, the screening execution command is sent to a ZC, if the ZC detects that an unscreened train exists and receives the screening execution command, whether a preset train safety condition is met is judged, and when the preset train safety condition is met, train screening operation is carried out on the unscreened train, and mobile authorization is initiated. Therefore, the ZC in the embodiment of the invention can timely find the train which is not subjected to screening on the current line, meanwhile, if a screening execution command sent by the ATS center side is received, and meanwhile, if the current condition also meets the preset train safety condition, the train screening action can be initiated, and the movement authorization is initiated, so that the operation efficiency is improved, the running safety of the train is ensured, and the technical problem that the train operation efficiency and the running safety are difficult to be simultaneously considered is solved.
On the basis of the foregoing embodiment, preferably, before the obtaining the screening execution command, the control method for train operation further includes:
if the third train is detected to be in a stop state, judging whether trains except the third train exist in the current axle counting;
if no train except the third train exists, judging whether the occupied state of the adjacent axle counting of the current axle counting is an idle state or not;
and if the idle state is in the idle state, generating a screening execution command.
It will be appreciated that the security detection will be performed before either the head screening operation or the tail screening operation is performed.
Specifically, whether the third train is in a stop state can be detected firstly, and if the third train is in the stop state, the train is characterized as being stopped stably; and the train carries out safety detection operation under the condition of complete standstill.
The safety detection operation may be performed manually, for example, by a train operator getting off the train, but is not limited thereto, and may be performed by an ATS center side.
Then, the detailed steps of the safety detection operation may be performed, specifically, it may be determined whether a train other than the third train exists in the current axle counting, and whether the occupied state of the adjacent axle counting of the current axle counting is an idle state.
This means that only one train of the present train is confirmed to be the axle of the train, no other trains are present, and if there is an adjacent axle, the occupied state of the adjacent axle of the train is confirmed to be idle.
Finally, after the above-mentioned manual safety detection condition is satisfied, a screening execution command may be sent to the ATS center.
In addition, after the above-mentioned manual safety detection condition is satisfied, a manual in-place screening confirmation may be sent to the ZC. After the ZC receives the confirmation of the manual in-situ screening, ZC safety condition protection is still needed to be carried out, and whether the safety condition of the ZC for the manual in-situ screening is met is judged.
The ZC safety condition protection mentioned herein can be implemented based on the above 6 preset train safety conditions.
On the basis of the foregoing embodiment, preferably, the preset train safety condition includes that a safety envelope of a VOBC corresponding to a train is within a jurisdiction of a ZC, the safety envelope of the VOBC is in a preset section, a screening state corresponding to the VOBC is an invalid state, an occupied state of an adjacent counting shaft of a counting shaft where the train corresponding to the VOBC is located is an idle state, other trains except for the train corresponding to the VOBC are in an unaccessible state, and the train corresponding to the VOBC is in a stopped state.
Fig. 4 is a first schematic diagram of a screening interaction flow according to an embodiment, another embodiment, and another embodiment of the present invention.
Referring to fig. 4, in particular, the ZC may periodically transmit manual in-place screening train information, i.e., the above-described train set, to the ATS center, and the ZC may also periodically transmit a manual confirmation screening request, i.e., the above-described in-place screening request, to the VOBC.
Then, after receiving the train set, the ATS center sends a manual confirmation screening verification command to the ZC, namely the verification command; after receiving the verification command, the ZC feeds back a manual verification screening verification command to the ATS center, namely the verification success information, or verification failure information.
Then, the ATS center may send a manual confirmation screening execution command, that is, the above screening execution command, to the ZC, which will perform the train screening operation and initiate the movement authorization, and finally, will feed back a manual confirmation screening execution confirmation command, that is, the above screening execution confirmation command, to the ATS center to inform that the screening is completed.
It can be seen that the first schematic diagram shown in fig. 4 corresponds to the interactive flow of screening confirmation performed at the ATS center side.
Since the ATS center side performs the screening confirmation, the transmission of the manual confirmation screening request to the VOBC can be stopped.
Fig. 5 is a second schematic diagram of a screening interaction flow according to an embodiment, another embodiment, and another embodiment of the present invention.
Referring to fig. 5, specifically, the ZC may periodically transmit a manual confirmation screening request, i.e., the above-mentioned on-site screening request, to the VOBC, and if the screening confirmation is performed by a driver on the VOBC side, the VOBC may feed back the manual confirmation screening result to the ZC.
It can be seen that the second schematic diagram shown in fig. 5 corresponds to the interactive procedure of the VOBC side for screening confirmation.
