Description
Technical Field
The application relates to the technical field of rail transit control, in particular to a non-communication vehicle occupation judging method and device, electronic equipment and a computer program product.
Background
In the mobile block train operation control system, a train reports the current operation direction, speed, head position, tail position, train integrity and other state information to a ground radio block center RBC device in real time, the RBC carries out sequencing management on the trains in the administrative range according to the operation state information reported by the communication train, and calculates the driving permission for the train by combining the state information of signal devices such as a section, a signal machine, a turnout and the like sent by a computer interlocking system (CI).
Before calculating the driving permission, the RBC needs to determine the occupation condition of the non-communication train in the section. If the interlock CI reports that a section is in an occupied state, and the RBC analyzes that a non-communication train occupies the section, the section is considered to possibly have trains, vehicles or foreign matters invading an operation line which are communicated with the RBC, and the section needs to be set to be occupied by the non-communication train.
When the RBC determines that no section occupied by the non-communication vehicle exists between the two sequenced communication vehicles, the driving permission end point calculated by the RBC for the rear vehicle is a position where the safety tail of the front vehicle is retracted by a safety protection distance (as shown in fig. 2).
When the RBC determines that a section occupied by the non-communication vehicle exists between the two sequenced communication vehicles, the driving permission destination calculated by the RBC for the following vehicle can be farthest to the maximum positioning error + safety protection distance of the train withdrawn backwards from the beginning of the section occupied by the non-communication vehicle (as shown in fig. 3).
For a line with a track circuit laid on the whole line, the interlocking judges the occupied/idle state of a section by acquiring the GJ state of a track relay of the section, taking a single section as an example: when the corresponding track relay GJ is collected to be sucked up, the section is judged to be free of vehicle occupation in an interlocking mode and is in an idle state; and when the corresponding track relay GJ is collected to fall down, judging that the section has the vehicle occupation and is in an occupation state.
According to the operation requirement of a line, a slow suction relay is adopted for preventing the light vehicle from jumping on a part of the track relay, and the slow suction time can be as long as 20 s. For the track section adopting the slow suction relay, when the train actually leaves the track section clearly, the GJ still falls down, the section state collected by interlocking still occupies, the GJ can be sucked up when the slow suction of the track relay is finished and no train occupies the section again in the period, the interlocking can collect the section idle state and report the section idle state to the RBC, and therefore in the actual operation process of the line, the rear train can not normally track the tail operation of the front train, the operation interval of the train is enlarged, and the running efficiency is reduced.

Detailed Description
To make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. 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 application.
Fig. 1 is a schematic flow chart of a non-communication vehicle occupancy determination method. Referring to fig. 1, an embodiment of the present application provides a non-communication vehicle occupancy determination method, which may include the steps of:
s1, when determining that the section to be determined has the train in the sequence, determining the section related to the train occupation section in the sequence as a non-communication train occupation section;
s2, when the section to be judged is in an occupied state and the section to be judged does not have the train in the sequence, judging whether the occupation condition of the adjacent section of the section to be judged meets a preset direct judgment condition;
s3, if yes, determining the section to be determined as a non-communication train occupation section;
and S4, if not, judging that the occupation situation of the adjacent section of the section to be judged meets the preset redundancy judgment condition, and judging the section to be judged as a non-communication train redundancy occupation section.
It should be noted that, aiming at the slow absorption characteristic of the track relay GJ in the track circuit, the embodiment of the present application provides a non-communication train occupancy determination scheme suitable for the track circuit, which divides the non-communication train occupancy determination of a section into direct determination and redundant determination. Specifically, whether a section meets a non-communication train occupation direct judgment condition or not is judged by combining the RBC with the sequencing condition of the train and the section occupation/idle state reported by the interlocking CI, if the section does not meet the condition, whether the section meets a non-communication train occupation redundancy judgment condition or not is judged, and a corresponding judgment result is output according to the condition meeting the condition. In the embodiment of the present application, it is understood that when the "direct determination" is that a non-communicating train occupies a zone, it means that it is certain that the zone is occupied by a non-communicating train, and when the "redundant determination" is that a non-communicating train redundantly occupies a zone, it means that the zone is suspected to be occupied by a non-communicating train, and then further determination is performed through a set redundant clearing step.
In the embodiment of the present application, first, when it is determined that there is an in-sequence train in the section to be determined, the section related to the in-sequence train occupation section may be directly determined as the non-communication train occupation section. Wherein, the train in the sequence refers to the train with the sequence number determined according to the train sequencing condition. For example, if the section to be determined is between a train with a sequence number of 1 and a train with a sequence number of 3, it is determined that there is an in-sequence train in the section to be determined (sequence number of 2). In this case, the relevant section occupied by the train with the serial number of 2 may be directly determined as the non-communication-vehicle occupied section. It can be understood that when a certain section is determined to be occupied by a non-communication vehicle, the driving permission end point calculated by the RBC for a following vehicle additionally considers the maximum positioning error of the train + the safety protection distance.
It is to be understood that the determination process of step S1 is also substantially a direct determination of occupancy of a non-communicating train, and the process of step S2 for making a zone determination based on the preset direct determination conditions is actually only a part of the direct determination. Specifically, in step S2, when the zone to be determined is in the occupied state and it is determined that there is no in-sequence train in the zone to be determined, it is determined whether the occupation status of the zone adjacent to the zone to be determined meets a preset direct determination condition.
It should be noted that, before performing redundancy determination, the above-mentioned direct determination process is performed, and if the to-be-determined section is directly determined as the non-communication train occupied section, the determination result is inherently directly input, and if the to-be-determined section cannot be directly determined as the non-communication train occupied section, the subsequent redundancy determination process needs to be performed. Specifically, when the occupation situation of the adjacent section of the section to be judged meets the preset redundancy judgment condition, the section to be judged is judged as the non-communication train redundancy occupation section.
The non-communication vehicle occupation judging method provided by the application is characterized in that the non-communication vehicle occupation judging of a section is divided into a direct judging mode and a redundant judging mode, firstly, the non-communication train occupation direct judging is carried out on the section according to a direct judging condition, when the non-communication train occupation section is not directly judged, the non-communication train redundant occupation judging is carried out on the section according to a redundant judging condition, the condition that the judgment result of the occupation state of the section is not consistent with the actual condition due to the slow absorption characteristic of a track relay in a track circuit can be avoided by implementing the embodiment of the application, and therefore the driving efficiency is improved on the premise of ensuring the driving safety.
In one embodiment, the segments associated with occupied train segments within the sequence include one or more of:
the section occupied by the train in the sequence when communication interruption occurs in the running process;
the section of the safe train head in the sequence without front end screening;
and the section of the safe tail of the train in the sequence without the rear-end screening.
In the embodiment of the present application, the section related to the occupied section of the train in the sequence described in the above embodiment may be any one of the above cases. For example, if a communication interruption occurs during the operation of a train with the serial number 2, the zone where the train is located when the communication interruption occurs can be directly determined as the non-communication-vehicle-occupied zone. In addition, if the train with the serial number of 2 does not complete front end screening, the zone where the safety locomotive of the train is located can be directly determined as the zone occupied by the non-communication train. In addition, if the train with the serial number of 2 does not complete the rear end screening, the section where the train safety tail is located can be directly determined as the non-communication vehicle occupied section.
According to the non-communication train occupation judging method provided by the embodiment of the application, the section related to the train occupation section is directly judged as the non-communication train occupation section according to the train communication condition and the screening detection condition in the sequence, so that the RBC calculates the driving permission end point for the rear train based on the judgment result, and the safety of train operation can be ensured to the maximum extent.
In one embodiment, the adjacent zone occupancy that satisfies the preset immediate decision condition includes one or more of:
the adjacent section of the section to be determined does not have a communication train, and the adjacent section is determined as a non-communication train occupying section;
a communication train exists in a front adjacent section of the section to be judged, and the last train in the train sequence in the front adjacent section is a position reporting train which does not complete rear end screening;
and communication trains exist in rear adjacent sections of the sections to be judged, and the foremost train in the train sequence in the rear adjacent sections is a position reporting train which does not complete front end screening.
In the embodiment of the present application, when the occupation situation of the adjacent zone of the zone to be determined belongs to any one of the above situations, that is, when it is determined that the direct determination condition is satisfied, the zone to be determined may be directly determined as the non-communication train occupation zone. It can be understood that, whether the direct determination or the redundant determination is performed, the to-be-determined section at this time is necessarily a section whose interlock CI report state is occupied, that is, when a section is in an occupied state, the section is taken as the to-be-determined section for occupancy determination, and on this basis, specifically: 1. when no communication train exists in the adjacent section of the section to be determined, and the adjacent section is already determined to be occupied by a non-communication train (occupied by the non-communication train in the front section or occupied by the non-communication train in the rear section), the section to be determined is also directly determined to be a non-communication train occupied section; 2. when a communication train exists in a front adjacent section (a section far away from the section to be determined along the train running direction in the adjacent section) of the section to be determined, and the last train in the train sequence in the front adjacent section is a position reporting train which does not complete rear end screening, the section to be determined is also directly determined as a non-communication train occupying section; 3. when a communication train exists in a rear adjacent section (a section which is close to the section to be determined along the train running direction in the adjacent section) of the section to be determined, and the foremost train in the train sequence in the rear adjacent section is a position reporting train which does not complete front end screening, the section to be determined is also directly determined as a non-communication train occupied section.
According to the non-communication vehicle occupation judging method provided by the embodiment of the application, whether the preset direct judgment condition is met or not is judged according to the occupation condition of the adjacent section of the section to be judged, if yes, the section to be judged is directly judged as the non-communication train occupation section, so that the RBC calculates the driving permission end point for the rear train based on the judgment result, and the safety of train operation can be ensured to the maximum extent.
In one embodiment, the adjacent segment occupancy that satisfies the preset redundancy decision condition includes one or more of:
the train with position report does not exist in the adjacent section of the section to be judged, and the adjacent section is in an idle state;
a communication train exists in a front adjacent section of the section to be judged, and the last train in the train sequence in the front adjacent section is a position reporting train which completes rear end screening;
and a communication train exists in a rear adjacent section of the section to be judged, and the foremost train in the train sequence in the rear adjacent section is a train which is subjected to front end screening and has a position report.
In the embodiment of the present application, when the occupation situation of the adjacent zone of the to-be-determined zone belongs to any one of the above situations, that is, when it is determined that the redundancy determination condition is satisfied, the to-be-determined zone may be determined as the non-communication train redundancy occupation zone. Specifically, the method comprises the following steps: 1. when the adjacent sections of the section to be judged do not have trains with front and rear end position reports and are idle, judging the section to be judged as a non-communication train redundant occupation section; 2. when a communication train exists in a front adjacent section of the section to be determined (a section far away from the section to be determined along the train running direction in the adjacent section), and the last train in the train sequence in the front adjacent section is a position reporting train for completing rear end screening, determining the section to be determined as a non-communication train redundant occupation section; 3. when a communication train exists in a rear adjacent section (a section which is close to the section to be determined along the train running direction in the adjacent section) of the section to be determined, and the foremost train in the train sequence in the rear adjacent section is a position reporting train which completes front end screening, the section to be determined is determined as a non-communication train redundant occupation section.
According to the non-communication vehicle occupation judging method provided by the embodiment of the application, after direct judgment, whether the preset redundant judgment condition is met or not is judged according to the occupation conditions of the adjacent sections of the section to be judged, if yes, the section to be judged is judged to be the non-communication train redundant occupation section, and therefore the driving efficiency is improved on the premise of ensuring the driving safety.
In one embodiment, the non-communication vehicle occupancy determination method further includes:
and after the section to be determined is determined as a non-communication train redundant occupied section, if a redundancy removing signal is not received within preset redundancy time, determining the section to be determined as the non-communication train occupied section. In one embodiment, the preset redundant time is set according to the track relay slow suction characteristic information of the section to be determined. In one embodiment, the redundancy elimination signal is sent when a communication train is monitored to enter the section to be determined.
In this embodiment of the application, after the to-be-determined section is determined as the non-communication train redundant occupied section, as the determination result obtained by determining according to the redundant determination condition, the actual occupancy condition of the section is to be further determined, for example, a redundant time (pending time) may be set, and the final determination result of the section is further finalized according to the monitoring condition in the redundant time, where the redundant time may be set according to the track relay slow-suction characteristic information of the section, for example, different track relays are used for tracks between stations and in-station sections, and have different slow-suction times, and then the redundant time may be set comprehensively according to the relay slow-suction time and other considerations of the actual condition. The scenario for triggering the redundancy release signal may be: and if the communication train which is fed back by the monitoring system to enter the section is received within the redundancy time, removing the redundancy judgment, otherwise, judging the section as a non-communication train occupying section.
According to the non-communication vehicle occupation judging method provided by the embodiment of the application, the redundancy time is set, and the exact judgment result corresponding to the redundancy judgment result is further determined according to the track monitoring condition in the redundancy time, so that the driving efficiency is improved on the premise of ensuring the driving safety; the redundancy time is determined according to the slow absorption characteristics of the track relays in different sections, the accuracy and reliability of redundancy judgment are effectively improved, and the driving efficiency is further improved on the premise of ensuring the driving safety.
Based on the above scheme, in order to better understand the non-communication vehicle occupancy determination method provided in the embodiment of the present application, the following specific description is made:
it should be noted that, in order to solve the problem that the occupied state of a section is not consistent with the actual situation due to the slow absorption characteristic of a track relay in a track circuit in a mobile block train operation control system, and further the operation interval is increased, the embodiment of the present application provides a non-communication vehicle occupation judgment scheme suitable for a track circuit.
The specific scheme flow is as follows:
1. non-communication train occupancy direct determination
The zone non-communication train occupation judgment is divided into two conditions of train existence and train non-existence in a zone train sequence to be judged, when a train exists in the train sequence, the zone is judged to be occupied by the non-communication train according to the following method:
1) in the running process of the communication train, communication is interrupted, and the section occupied by the train at the moment is judged to be occupied by a non-communication train;
2) in the running process of a communication train (the head of which is provided with a suspicious mark) which does not finish front-end screening, judging a section where a safety locomotive of the communication train is positioned as non-communication train occupation;
3) and in the running process of the communication train (the tail part of which has the suspicious mark) without rear-end screening, judging the section where the tail part of the safety train is positioned as non-communication train occupation.
When the current interlocking CI report state of the section to be judged is occupied and no vehicle exists in the train sequence of the section, judging that the non-communication train in the section is occupied according to the following rules:
1) no communication train exists in the adjacent zone, and the adjacent zone is judged to be occupied by a non-communication train (occupied by a front zone non-communication train or occupied by a rear zone non-communication train);
2) communication trains exist in adjacent sections, the adjacent sections are sections far away from the section to be judged along the train running direction, and the last train in the train sequence in the adjacent sections is a position reporting train which does not complete rear end screening;
3) the communication train exists on the adjacent section, the adjacent section is the section which is close to the section to be judged along the train running direction, and the first train in the train sequence in the adjacent section is the position reporting train which does not finish front end screening.
2. Non-communicating train occupancy redundancy determination
When the current interlock CI report state of the section to be judged is occupied and no train exists in the train sequence of the section, the RBC judges that the section is redundantly occupied by a non-communication train when one of the following conditions is met:
1) the adjacent sections are not provided with trains reported at the front end and the rear end, and the adjacent sections are idle;
2) a communication train exists in an adjacent section (the adjacent section is a section far away from the section to be judged along the train running direction), and the last train in the train sequence in the adjacent section is a position reporting train which completes rear end screening;
3) a communication train exists in an adjacent section (the adjacent section is a section close to the section to be determined along the train running direction), and the first train in the train sequence in the adjacent section is a position reporting train which completes front end screening.
When the ground RBC equipment judges that the section is occupied by the non-communication train redundantly, if no communication train runs into the section to be judged after a certain redundancy time, the RBC judges that the section is occupied by the non-communication train.
The 'redundant time' is determined by the slow suction characteristic of a track relay GJ in a track circuit, the slow suction time of the GJ in the track circuit between stations and in the stations is different according to the operation characteristics of different lines, and the sections between the stations and in the stations can be judged by using different 'redundant time' respectively according to actual conditions.
Compared with the prior art, the slow absorption characteristic of the track relay is considered, the non-communication vehicle occupation judgment of the section is divided into a direct judgment mode and a redundant judgment mode, the result that the judgment result of the section occupation state is inconsistent with the actual situation due to the slow absorption characteristic of the track relay in the track circuit is avoided, and therefore safer and more efficient driving permission is guaranteed to be output by the RBC.
The following describes the non-communication vehicle occupancy determination device provided in the embodiment of the present application, and the non-communication vehicle occupancy determination device described below and the non-communication vehicle occupancy determination method described above may be referred to in correspondence with each other.

and the redundancy judging module 3 is used for judging that the to-be-judged section is in an occupied state and determining that the to-be-judged section does not have the train in the sequence, if the occupation condition of the adjacent section of the to-be-judged section does not meet a preset direct judgment condition, and when the occupation condition of the adjacent section of the to-be-judged section meets a preset redundancy judgment condition, judging the to-be-judged section as a non-communication train redundancy occupation section.
