Description
Technical Field
The application relates to the technical field of rail transit control, in particular to a non-communication vehicle occupation judging method, a non-communication vehicle occupation judging device, electronic equipment and a computer program product.
Background
In the running control system of the mobile block train, the state information such as the current running direction, speed, head position, tail position, train integrity and the like is reported to the RBC equipment of the ground wireless block center in real time by the train, the RBC carries out sequencing management on the trains in the management range according to the running state information reported by the communication train, and calculates running permission for the trains by combining the state information of signal equipment such as a section, a annunciator, a turnout and the like sent by a computer interlocking system (CI).
Before calculating the driving license, the RBC needs to judge the situation of non-communication train occupation in the section. If the interlock CI reports that a section is occupied, and no communication train occupies the section after RBC analysis, it is considered that there may be a train, a vehicle or foreign matter invading the operation line, which is in communication with RBC, in the section, and the section needs to be set to be occupied by a non-communication train.
When the RBC judges that no section occupied by the non-communication vehicle exists between the two ordered communication vehicles, the RBC calculates a driving permission end point for the rear vehicle as a position of retracting a safety protection distance of the front vehicle safety tail (shown in fig. 2).
When the RBC judges that a section occupied by the non-communication vehicle exists between the two sequenced communication vehicles, the RBC can furthest reach the position of the maximum positioning error plus the safety protection distance of the train after the start end of the section occupied by the non-communication vehicle is retracted for the driving permission end point calculated by the rear vehicle (as shown in figure 3).
For the line of the full-line track laying circuit, the occupation/idle state of the section is judged by the state of the track relay GJ of the acquisition section by interlocking, taking a single section as an example: when the corresponding track relay GJ is collected and sucked up, the section is judged to be unoccupied by the vehicle in an interlocking mode and is in an idle state; when the corresponding track relay GJ is collected to fall, judging that the section is occupied by the vehicle and is in an occupied state.
According to the operation demand of circuit, for preventing light car run-out part track relay adopts slowly inhale the relay, slowly inhale the time and can reach 20s. For the track section adopting the slow suction relay, when the train actually exits the clear track section, the GJ still falls, the section state acquired by interlocking is still occupied, the GJ is sucked up when the track relay slowly sucks and no train occupies the section again during the slow suction process, the interlocking can acquire the idle state of the section and report the 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 driving efficiency is reduced.

Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present application more apparent, the technical solutions of the present application will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.
Fig. 1 is a flow chart of a non-communication vehicle occupation judging method. Referring to fig. 1, an embodiment of the present application provides a non-communication vehicle occupation determining method, which may include the steps of:
s1, when determining that a section to be determined has a train in a sequence, determining a 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 is determined to have no train in the sequence, judging whether the occupation condition of the adjacent sections of the section to be judged meets a preset direct judgment condition;
s3, if yes, judging the section to be judged as a non-communication train occupation section;
s4, if not, judging the section to be judged as the non-communication train redundancy occupation section when judging that the occupation condition of the adjacent sections of the section to be judged meets the preset redundancy judgment condition.
The embodiment of the application provides a non-communication train occupation judging scheme suitable for a track circuit aiming at the slow suction characteristic of a track relay GJ in the track circuit, and the non-communication train occupation judgment of a section is divided into direct judgment and redundancy judgment. Specifically, by combining the sequencing condition of trains and the section occupation/idle state reported by the interlocking CI through RBC, firstly judging whether the section meets the non-communication train occupation direct judging condition, if not, judging whether the section meets the non-communication train occupation redundancy judging condition, and outputting a corresponding judging result according to the condition that the condition is met. In the embodiment of the application, it can be understood that when the "direct determination" is that the non-communication train occupies the section, the section can be affirmed to be occupied by the non-communication train, and when the "redundancy determination" is that the non-communication train redundantly occupies the section, the section is suspected to be occupied by the non-communication train, and then the further determination is performed through a set redundancy clearing step.
In the embodiment of the application, firstly, when determining that the section to be determined has the train in the sequence, the section related to the train occupation section in the sequence can be directly determined as the non-communication train occupation section. The trains in the sequence refer to trains with serial numbers determined according to the train sorting condition. For example, if the section to be determined is between the train with the sequence number 1 and the train with the sequence number 3, it is determined that the section to be determined has an in-sequence train (sequence number 2). At this time, 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 will be appreciated that when a zone is determined to be occupied by a non-communicating vehicle, the RBC will additionally consider the train maximum positioning error + safety distance for the end point of the travel grant calculated for the following vehicle.
It will be appreciated that the determination process of step S1 is also substantially a direct determination of non-communication train occupation, and the process of performing the section determination according to the preset direct determination condition of step S2 is only a part of the direct determination in practice. Specifically, in step S2, when the section to be determined is in the occupied state and it is determined that the section to be determined does not have the train in the sequence, it is determined whether the occupation condition of the adjacent sections of the section to be determined satisfies a preset direct determination condition.
Before performing redundancy determination, the above-mentioned direct determination process is performed, if the section to be determined is directly determined as the non-communication train occupation section, the determination result is simply input directly, and if the section to be determined cannot be directly determined as the non-communication train occupation section, a subsequent redundancy determination process is required. Specifically, when judging that the occupation condition of the adjacent sections of the section to be judged meets a preset redundancy judgment condition, judging the section to be judged as a non-communication train redundancy occupation section.
According to the non-communication train occupation judging method, the non-communication train occupation judgment of the sections is divided into two modes of direct judgment and redundancy judgment, the non-communication train occupation is firstly judged directly according to the direct judgment condition, and when the non-communication train occupation is not judged directly as the non-communication train occupation section, the non-communication train redundancy occupation judgment is carried out on the sections according to the redundancy judgment condition.
In one embodiment, the section associated with the intra-train occupancy section includes one or more of the following:
the section occupied by the train in the sequence when communication interruption occurs in the running process;
the section where the safety locomotive of the train is located in the sequence of incomplete front-end screening;
and (3) a section where the safety tail of the train is located in the sequence without finishing the rear-end screening.
In the embodiment of the present application, the section related to the train occupation section in the sequence described in the above embodiment may be any of the cases described above. For example, if a communication interruption occurs during the running of the train with the serial number of 2, the section where the train is located when the communication interruption occurs may be directly determined as the non-communication vehicle-occupied section. In addition, if the train with the serial number of 2 does not finish front end screening, the section where the train safety locomotive is located can be directly judged as a non-communication train occupation section. In addition, if the train with the serial number of 2 does not finish the rear end screening, the section where the train safety tail is located can be directly determined as the non-communication train occupation 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 RBC calculates the driving permission end point for the rear train based on the judging result, and the running safety of the train can be ensured to the greatest extent.
In one embodiment, the adjacent segment occupancy meeting the preset direct determination condition includes one or more of the following:
A communication train does not exist in an adjacent section of the section to be determined, and the adjacent section is determined as a non-communication train occupation 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 with incomplete rear-end screening;
and a communication train exists in a rear adjacent section of the section to be determined, and the forefront train in the train sequence in the rear adjacent section is a position reporting train with incomplete front end screening.
In the embodiment of the present application, when the occupation condition of the adjacent section of the section to be determined belongs to any one of the above conditions, that is, the condition of direct determination is determined to be satisfied, and at this time, the section to be determined may be directly determined to be the non-communication train occupation section. It will be understood that, whether it is direct determination or redundant determination, the section to be determined at this time must be the section whose interlock CI report status is occupied, that is, when a certain section is occupied, this section will be taken as the section to be determined to perform the occupation determination, and specifically, on this basis: 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 the non-communication train (the front section is occupied by the non-communication train or the rear section is occupied by the non-communication train), the section to be determined is also directly determined to be the 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 running direction of the train 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 report train with incomplete rear-end screening, the section to be determined is also directly determined as a non-communication train occupation section; 3. when a communication train exists in a rear adjacent section (a section which is close to the section to be determined in the train running direction in the adjacent sections) of the section to be determined, and the forefront train in the train sequence in the rear adjacent section is a position report train with incomplete front end screening, the section to be determined is also directly determined as a non-communication train occupation section.
According to the non-communication vehicle occupation judging method provided by the embodiment of the application, whether the preset direct judging condition is met is judged according to the occupation condition of the adjacent sections of the section to be judged, if so, the section to be judged is directly judged to be the non-communication train occupation section, so that the RBC calculates the driving permission end point for the rear vehicle based on the judging result, and the running safety of the train can be ensured to the greatest extent.
In one embodiment, the adjacent segment occupancy meeting the preset redundancy determination condition includes one or more of the following:
the adjacent section of the section to be judged has no train with position reporting, 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 for finishing rear-end screening;
And a communication train exists in a rear adjacent section of the section to be determined, and the forefront train in the train sequence in the rear adjacent section is the train with the position report for completing front end screening.
In the embodiment of the present application, when the occupation condition of the adjacent section of the section to be determined belongs to any one of the above conditions, that is, the condition of redundancy determination is determined to be satisfied, at this time, the section to be determined may be determined to be the non-communication train redundancy occupation section. Specifically: 1. when the adjacent sections of the section to be judged do not have trains reported by the front end position and the rear end position and are idle, judging the section to be judged as a non-communication train redundancy occupation section; 2. when a communication train exists in a front adjacent section (a section far away from the section to be judged along the running direction of the train in the adjacent section) of the section to be judged, and the last train in the train sequence in the front adjacent section is a position report train for completing rear-end screening, judging the section to be judged as a non-communication train redundancy 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 running direction of the train in the adjacent section) of the section to be determined, and the forefront train in the train sequence in the rear adjacent section is a position report train for completing front end screening, the section to be determined is determined to be a non-communication train redundancy occupation section.
According to the non-communication train occupation judging method provided by the embodiment of the application, after the direct judgment is carried out, whether the preset redundancy judging condition is met or not is judged according to the occupation condition of the adjacent sections of the section to be judged, if so, the section to be judged is judged to be the non-communication train redundancy occupation section, and therefore the driving efficiency is improved on the premise of ensuring the driving safety.
In one embodiment, the non-communication vehicle occupation judging method further includes:
And after the section to be determined is determined to be the non-communication train redundancy occupied section, if the redundancy release signal is not received within the preset redundancy time, the section to be determined is determined to be the non-communication train occupied section. In one embodiment, the preset redundancy time is set according to the track relay slow-suction characteristic information of the section to be determined. In one embodiment, the redundancy release signal is issued when a communication train is detected to be driven into the section to be determined.
In the embodiment of the present application, after the section to be determined is determined as the non-communication train redundancy occupied section, since the determination result is obtained by determining according to the redundancy determination condition, the actual occupancy condition of the section needs to be further determined, for example, a redundancy time (waiting time) may be set, and the final determination result of the section may be further determined according to the monitoring condition in the redundancy time, where the redundancy time may be set according to the track relay slow-suction characteristic information of the section, for example, the tracks of the inter-station and intra-station sections adopt different track relays and have different slow-suction times, and the redundancy time may be set comprehensively according to the relay slow-suction time and other considerations of the actual condition. The scenario of triggering the redundancy release signal may be: and if the received monitoring system feeds back that the communication train enters the section within the redundancy time, the redundancy judgment is released, and otherwise, the section is judged to be a non-communication train occupation section.
According to the non-communication vehicle occupation judging method provided by the embodiment of the application, the exact judging result corresponding to the redundant judging result is further determined by setting the redundant time and according to the track monitoring condition in the redundant 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 suction characteristics of the track relays in different sections, so that the accuracy and reliability of redundancy judgment are effectively improved, and the driving efficiency is further improved on the premise of ensuring driving safety.
Based on the above scheme, in order to better understand the non-communication vehicle occupation judging method provided by the embodiment of the application, the following is specifically described:
It should be noted that, in order to solve the problem that the occupied state of the section is different from the actual situation and the running interval is increased due to the slow suction characteristic of the track relay in the track circuit in the running control system of the mobile block train, the embodiment of the application provides a non-communication vehicle occupation judging scheme suitable for the track circuit, and before the RBC system calculates the running permission for the running train in the jurisdiction, the scheme is adopted to judge the non-communication vehicle occupation situation of the section in the jurisdiction, thereby ensuring the running permission of the RBC output to be safer and more efficient.
The specific scheme flow is as follows:
1. non-communication train occupation direct determination
The section non-communication train occupation judgment is divided into two situations of presence and absence of a train in a train sequence of a section to be judged, and when the train is present in the train sequence, the section is judged to be the non-communication train occupation 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 the non-communication train;
2) In the running process of the communication train (with suspicious marks on the head) with incomplete front-end screening, judging the section where the safety train head is located as the occupation of the non-communication train;
3) And in the running process of the communication train (suspicious mark at the tail part) with incomplete back-end screening, judging the section where the safety tail is positioned as the occupation of the non-communication train.
When the current interlocking CI reporting state of the section to be judged is occupied and no train exists in the train sequence of the section, judging that the section non-communication train occupies according to the following rule:
1) No communication train is present on the adjacent section, and the adjacent section has been judged as being non-communication train-occupied (front section non-communication train-occupied or rear section non-communication train-occupied);
2) The adjacent sections are sections far away from the section to be judged along the running direction of the trains, and the last train in the train sequence in the adjacent sections is a position reporting train with incomplete rear-end screening;
3) The communication trains exist in adjacent sections, the adjacent sections are sections which are close to the sections to be judged along the running direction of the trains, and the first train in the train sequence in the adjacent sections is a position reporting train with incomplete front-end screening.
2. Non-communication train occupation redundancy determination
When the current interlock CI reporting state of the section to be judged is occupied and no train exists in the train sequence of the section, and one of the following conditions is met, the RBC judges that the section is occupied by the non-communication train in a redundancy way:
1) The adjacent sections are idle, and trains reported by front and rear end positions do not exist on the adjacent sections;
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 running direction of the train), and the last train in the train sequence in the adjacent section is a position reporting train for finishing the rear-end screening;
3) There is a communication train on an adjacent section (the adjacent section is a section that is close to the section to be determined in the train running direction), and the first train in the train sequence in the adjacent section is a reporting train with a position that completes the front-end screening.
When the ground RBC equipment judges that the section is occupied by the non-communication train in a redundant manner, if a certain redundant time is passed and no communication train still enters the section to be judged, the RBC judges that the section is occupied by the non-communication train.
The redundancy time is determined by the slow suction characteristic of the track relay GJ in the track circuit, and the slow suction time of the GJ in the track circuit between the stations and in the stations is different due to the operation characteristics of different lines, so that the stations and the sections in the stations can be judged by using different redundancy times respectively according to actual conditions.
Compared with the prior art, the embodiment of the application considers the slow suction characteristic of the track relay, divides the non-communication vehicle occupation judgment of the section into two modes of direct judgment and redundancy judgment, and avoids the inconsistent judgment result of the section occupation state caused by the slow suction characteristic of the track relay in the track circuit, thereby ensuring the safe and efficient running permission of RBC output.
