Detailed Description
In order to make the technical solutions and advantages of the embodiments of the present application more apparent, the following detailed description of exemplary embodiments of the present application is given with reference to the accompanying drawings, and it is apparent that the described embodiments are only some of the embodiments of the present application and not exhaustive of all the embodiments. It should be noted that, in the case of no conflict, the embodiments and features in the embodiments may be combined with each other.
First, the abbreviations appearing in this example are explained:
IC: an integrated circuit Chip Integrated Circuit Chip;
CTC: a dispatch centralized system centralized traffic control system;
CI: interlocking, computer Interlocking;
RBC: a radio block center Radio Block Center;
TSRS: temporary speed limit server Temporary Speed Restriction Server.
Temporary speed limit server (Temporary Speed Restriction Server, TSRS for short):
currently, a three-display or four-display fixed block signal system is commonly adopted in freight railways, and a driver drives a train with the aid of a train operation monitoring device (for example, LKJ2000, hereinafter abbreviated as LKJ), wherein the LKJ device can prevent the train from entering signals and overspeed operation. The LKJ equipment is required to load temporary speed limiting information written in the IC card in advance, and in the running process of the train, the LKJ comprehensive line information, the temporary speed limiting information, the running state of the train and other information are subjected to overspeed protection. Under the fixed blocking signal system, a dispatching centralization system (CTC) and a computer interlocking system (CI) are communicated, and commands issued by dispatching centralization to the interlocking are transmitted; the CI transmits real-time station information, various alarm information and the like to the CTC.
In the upgrading and reconstruction of the freight railway mobile blocking system, the jurisdiction of a newly added Radio Blocking Center (RBC) and a temporary speed limiting server (TSRS) are required to be divided. In order to calculate a real and reliable driving license for a train, RBC needs to interact information with CIs in the jurisdiction of the RBC in real time, one RBC can jurisdiction a plurality of CIs, and a single CIs is only jurisdictiond by one RBC. The TSRS can receive the temporary speed limit command issued by the CTC and forward corresponding speed limit information to the RBC to be issued by the RBC to the train, and the single TSRS only fixedly receives the speed limit command issued by one CTC, and the jurisdiction boundary of the TSRS is consistent with that of the CTC. Under the existing train operation control system, the communication relation between the TSRS and the RBC is 'one-to-many', namely, a single RBC only obtains speed limit information from one TSRS.
However, considering that the operation types of CI sites of existing freight railway lines are different, the line situation is more complex than that of ordinary passenger lines, because the RBC has limited capability of calculating driving permissions for a plurality of trains at the same time, when encountering a large freight operation station, the RBC has limited range of CI stations that can be administered, as shown in fig. 2, when the administration range of the RBC overlaps with two CTC administration ranges at the same time, temporary speed limit information cannot be issued normally.
Therefore, for upgrading and reforming the mobile blocking system of the existing freight railway line, the embodiment of the application provides a new temporary speed limiting issuing mode so as to ensure the safe operation of the train.
Fig. 1 is a flowchart of a temporary speed limit issuing method for a train provided in an embodiment of the present application, please refer to fig. 1:
s1: and issuing temporary speed limiting commands to the first speed limiting area and the second speed limiting area through the first CTC and the second CTC respectively. Specifically, the first speed limit region is adjacent to the second speed limit region.
In a specific implementation, two adjacent speed limiting areas belong to two speed limiting areas which are governed by the CTC and correspond to the overlapped speed limiting areas at the CTC demarcation points.
In some embodiments of the present application, the first CTC and the second CTC issue temporary speed limit commands to the first speed limit area and the second speed limit area through the first TSRS and the second TSRS, respectively; the jurisdictions of the first and second TSRS are the same as the first and second CTCs, respectively.
In some embodiments of the present application, RBC calculates a train movement permit from the train position information and the CI status information, and adds temporary speed limit start information and temporary speed limit end information to the train movement permit according to the temporary speed limit command. Specifically, the CI status information includes at least one of section, road, and switch status information.
For the information interaction manner under the mobile block control system provided in the embodiment of the present application, please refer to fig. 3 specifically, in the implementation, under the mobile block control system, CTCs issue temporary speed limit commands to TSRS, TSRS forwards temporary speed limit information corresponding to the received speed limit commands to RBCs, CI reports status information of sections, routes, switches and the like in its jurisdiction to ground RBC equipment in real time, trains report train position information to RBCs in real time, and RBCs acquire temporary speed limits in the jurisdiction. Based on the application of TSRS, the train realizes information interaction under a mobile blocking control system, and under the traditional fixed blocking system, the system cannot know the specific position of the train in a subarea, so that the starting point and the ending point of train braking are always at the boundary of a subarea. In order to fully ensure safety, a protection section must be added between two trains, so that the safety interval between the trains is larger, and the use efficiency of the circuit is affected; based on the mobile blocking control system combined by the embodiments of the application, the train speed control can be improved, the train safety interval can be reduced, and the line utilization efficiency can be improved.
In some of the embodiments of the present application, as shown in fig. 2, the jurisdiction of RBCs may overlap with two CTC jurisdictions at the same time, i.e., two adjacent speed limit areas may be in the case of being administered by the same RBC, but by different CTCs and TSRS. In other embodiments of the present application, it may also occur that the jurisdiction of RBCs is consistent with CTCs and TSRS.
Please continue to refer to fig. 1:
s2: if there is no common RBC jurisdiction for the first and second speed limit regions, then:
the first RBC in the first speed limit area is used for receiving and executing the temporary speed limit command issued by the first CTC, and the second RBC in the second speed limit area is used for receiving and executing the temporary speed limit command issued by the second CTC.
In some embodiments of the present application, the first RBC and the second RBC calculate a train driving license according to the train position information and the CI state information, and add temporary speed limit start information and temporary speed limit end information to the train driving license according to the temporary speed limit command.
In a specific implementation, for a scenario that the RBC jurisdiction is only overlapped with a single CTC jurisdiction, the RBC may be administered by a single TSRS, and after the TSRS receives a temporary speed limit command issued by the CTC, the temporary speed limit information is issued to the RBC administered by the line, so that train management through the temporary speed limit area is realized by the RBC.
For a scenario in which the RBC jurisdiction is only overlapped with a single CTC jurisdiction, the issuing, receiving and executing of the speed limit command are respectively performed in two adjacent speed limit areas and the steps are substantially the same, so in this embodiment, only one section of the speed limit areas is selected to perform the specific description of issuing, receiving and executing of the speed limit command. As shown in fig. 4, when there is a continuous temporary speed limit on the lines CI1 to CI2, the dispatcher issues a corresponding speed limit command to the TSRS at the CTC, and the TSRS confirms that the continuous speed limit area is within the jurisdiction of RBC1 after receiving the speed limit command, i.e. in this embodiment, the jurisdiction of RBC is consistent with the CTC and the TSRS. And forwarding the segment of speed limiting area to the RBC, so that the RBC acquires the segment of temporary speed limiting information.
Based on the position information reported by the train to the controlled RBC in real time, the RBC calculates driving permission for the train by combining the information such as the section, the route, the turnout state and the like reported by the CI in the jurisdiction, when the RBC determines that the driving permission of the train passes through the temporary speed limit area, the determined temporary speed limit starting end information and the determined temporary speed limit terminal information are added into the real-time driving permission information and are sent to the vehicle-mounted equipment, the vehicle-mounted equipment calculates the speed limit of the train according to the driving permission information received in real time, the speed of the train is controlled to be reduced to be smaller than or equal to the temporary speed limit value before the locomotive enters the temporary speed limit starting end position, the train does not need to stop stably in the temporary speed limit area, and the train is accelerated after the train tail completely leaves the temporary speed limit area, so that the driving safety is ensured, and the running efficiency of the train is improved.
Please continue to refer to fig. 1:
s3: if there is a common RBC jurisdiction for the first and second speed limit regions, then:
the temporary speed limit command issued by the first CTC and the second CTC is received and executed by the common RBC of the first speed limit zone and the second speed limit zone.
Based on the above, the embodiment of the application solves the problem that temporary speed limit information cannot be normally issued when the jurisdiction of the RBC is overlapped with two CTC jurisdictions at the same time due to the limitation of the running permission calculation capability of the RBC when the existing freight railway line is upgraded and transformed into the mobile blocking system.
In some embodiments of the present application, after the first CTC and the temporary speed limit command issued by the second CTC are received by the common RBC of the first speed limit area and the second speed limit area, if the speed limit values of the first speed limit area and the second speed limit area are the same, the first speed limit area and the second speed limit area are spliced into a continuous speed limit area, and the temporary speed limit command is executed by the common RBC in the continuous speed limit area.
In some embodiments of the present application, the common RBC calculates a train movement permit based on the train position information and the CI status information, and adds temporary speed limit start information and temporary speed limit end information to the train movement permit based on the temporary speed limit command.
In this embodiment, for a scenario in which the jurisdiction of the RBC and two CTC jurisdictions overlap at the same time, in order to ensure that temporary speed-limiting information can be completely issued to the RBC, the RBC acquires temporary speed-limiting information from TSRS in the two CTC jurisdictions at the same time, and for speed-limiting information in which speed-limiting areas overlap at CTC demarcation points and speed-limiting values are consistent, the RBC determines a continuous temporary speed-limiting, and splices the continuous speed-limiting information into a complete temporary speed-limiting area for train management.
As shown in fig. 5, when the lines from CI4 to CI5 have a continuous temporary speed limit, the dispatcher splits the temporary speed limit into two pieces according to the jurisdiction of CTCs, and issues corresponding temporary speed limit commands on CTC1 and CTC2 respectively, after receiving the speed limit commands, TSRS1 and TSRS2 determine that the temporary speed limit area is within the jurisdiction of RBC2, TSRS1 sends temporary speed limit information 1 to RBC2, TSRS2 sends temporary speed limit information 2 to RBC2, after RBC receives, confirms that the temporary speed limit information 1 and the speed limit area corresponding to the temporary speed limit information 2 overlap at the CTC boundary point and the speed limit values are consistent, and then splices the temporary speed limit information 1 and the speed limit areas into a continuous temporary speed limit for management. Based on the method, the train does not need to stop and stably runs in the temporary speed limiting area, and the speed is increased after the tail of the train completely exits the temporary speed limiting area, so that continuous control on the running of the train is realized, and continuous control on the train under the condition that the temporary speed limiting exists by the mobile blocking system is realized.
In the embodiment, the train reports position information to the controlled RBC in real time, the RBC calculates driving permission for the train in combination with information such as the state reported by CI in jurisdiction, when the RBC determines that the driving permission of the train passes through the temporary speed limiting area, the determined temporary speed limiting initial end information and temporary speed limiting terminal information are added into the real-time driving permission information and sent to the vehicle-mounted equipment, the vehicle-mounted equipment calculates the speed limit of the train according to the driving permission information received in real time, the speed of the train is controlled to be reduced to be smaller than or equal to the temporary speed limiting value before the locomotive enters the temporary speed limiting initial end position, and the running efficiency of the train is improved while the driving safety is ensured. Furthermore, the status information content reported by taking the sections, the roads and the turnouts as CI can calculate the train driving license more accurately.
In other embodiments of the present application, if the speed limit values of two adjacent speed limit areas are inconsistent, the two speed limit areas are not spliced into a continuous temporary speed limit for management, and the speed limit command is issued to the two speed limit areas respectively.
In summary, for the case that the RBC jurisdiction is only overlapped with a single CTC jurisdiction or is overlapped with two CTC jurisdictions at the same time, the RBC can acquire temporary line speed limit information in the jurisdiction, and further manage the train passing through the temporary speed limit area.
