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.
Aiming at the defects in the prior art, in the freight train operation scene, the train operation state information, the speed information and the kilometer post information of the front and the rear of the current train are mastered in real time, so that the method has great significance for drivers to safely drive the train, and the drivers timely control the operation state of the current train according to the real-time operation state, the speed and the kilometer post information of the front and the rear trains so as to ensure the safety and the efficiency of the whole line.
Fig. 3 is a schematic flow chart of a train information interaction method provided by the present invention, as shown in fig. 3, including:
s1, determining the running information set of the current train;
s2, respectively acquiring the running state information of the tracked train in front of the current train and the running state information of the tracked train in back in the RBC coverage range of a plurality of adjacent radio block centers based on the running information set;
and S3, combining the front tracked train running state information and the rear tracked train running state information, and dynamically adjusting the current running state of the current train.
Firstly, the current train is taken as a reference, the current train continuously reports position, running state, train formation information and the like, and the ground RBC equipment normally calculates the driving permission for the front train and inquires the information of the front train and the rear train.
Generally, in the operation of a freight train, when the freight train is too long and the braking distance is too long, the distance between the freight train and the train is required to be at least 4 kilometers to ensure the running safety under the tracking condition that the front train and the rear train run at full speed. At this time, due to the design of the station yard, the train information of the front train and the rear train cannot be found for the current train in the administrative scope of the RBC. Therefore, information of related trains needs to be interacted through adjacent RBCs, so that the requirement that the information of the front train and the rear train is not lost in the current train in the running process of the front train and the rear train which are not in the same RBC jurisdiction range is met.
Further, after the acquisition of the front and rear train information of the current train in the running process is alternately completed through a plurality of adjacent RBCs, the state of the vehicle is adjusted in real time by the front and rear train information comprehensively obtained by the current train so as to obtain the optimal relative control of running and braking, as shown in fig. 4, the freight train can timely process the abnormal condition of the front and rear running trains in advance, for example, if the speed of the rear train is too high and the distance from the current train is too short and is less than the safe distance, the freight train can advance with acceleration and give an early warning to the rear train in time, or the speed of the front train is too slow, the distance between the front train and the freight train is smaller than the safe distance, the freight train needs to be decelerated or emergently braked in time, and the front train needs to be warned, the states of the front and rear vehicles are adjusted in time, and the distance between the front and rear vehicles is always kept within a safe distance range.
According to the invention, the information of the front train and the rear train is interacted among a plurality of adjacent RBCs, so that the train and the tracked train can be tracked before and after the current train is inquired, the inquiry range covers the jurisdiction area of the adjacent RBCs, the operation efficiency is greatly improved, and the potential safety hazard is reduced.
Based on the above embodiment, the method step S1 includes:
and acquiring the reporting position, the running direction and the interlocking reporting station information of the current train.
Optionally, the ground RBC device continuously obtains relevant information of the current train, including but not limited to information of a reporting position, a running direction, an interlocking reporting station and the like of the current train, and the train can be tracked and traced before and after searching, and if the train is not in the jurisdiction range of the RBC, the query is stopped.
Here, the RBC should send the inquired running state information of the front communication train as the preceding train information to the current train; and meanwhile, the running state information of the rear communication train is used as the rear train information and sent to the current train.
Before the information of the front train and the rear train is acquired, the ground RBC analyzes the current train state relatively comprehensively by using the acquired relevant information of the current train as reference data for comparing with the information of the front train and the rear train, and provides accurate basic data for the real-time data comparison and adjustment process.
Based on any of the above embodiments, the method step S2 includes:
determining the jurisdiction RBC of the current train, and judging the working mode of the jurisdiction RBC;
if the administered RBC is a handover RBC, exchanging the running state information of the front tracked train with a connecting RBC before running;
and if the administered RBC is a takeover RBC, exchanging the rear tracking train operation state information with a handover RBC after operation.
It should be noted that, in a freight train scene, because the train braking distance is relatively long, in the distance between the front train and the rear train, the acquisition and interaction of the information of the front train and the rear train cannot be completed only by a single RBC device, and a working mode in which a plurality of adjacent RBC devices perform front-rear relay switching is required, so that all data can be completely and accurately acquired in the train operation process.
It can be understood that, taking the jurisdiction RBC in which the current train is located as a reference, in the route direction, relative to the front and back directions of the jurisdiction RBC, the present invention defines two working modes of handover RBC and takeover RBC, which are both relative and dynamic.
If the administrative RBC is taken as the handover RBC, the adjacent RBC in front is taken as the takeover RBC, and the administrative RBC acquires the running state information of the front tracked train through the takeover RBC;
if the administrative RBC is taken as the takeover RBC, the adjacent RBC located behind is the handover RBC, and the administrative RBC acquires the running state information of the rear tracking train through the handover RBC.
According to the invention, different roles of a plurality of adjacent RBCs are defined, so that the state information of the front train and the rear train can be dynamically acquired in real time, and the current train can be adjusted according to the latest train state to obtain the optimal operation adjustment result.
Based on any of the above embodiments, if the jurisdictional RBC is a handover RBC, interacting the running state information of the front tracked train with a takeover RBC before running, including:
determining a forward vehicle demarcation point between the jurisdictional RBC and a takeover RBC ahead of the run;
the administrative RBC periodically sends the passing train information which is closest to the boundary point of the previous train in the current administrative range of the administrative RBC to a takeover RBC before the operation, wherein the passing train information is the state of finished front-end screening;
and after receiving the front train information sent by the takeover RBC in front of the operation, the jurisdiction RBC sends the front train information to a passing train which is closest to the front train boundary point in the current jurisdiction range of the jurisdiction RBC, wherein the passing train is in a state of completing front end screening.
Optionally, when the jurisdictional RBC is a handover RBC, the information related to the passing train which completes front-end screening and is closest to the boundary point in the jurisdiction range of the jurisdiction range is periodically sent to the take-over RBC, as shown in fig. 5;
meanwhile, when the relevant information of the communication train which takes over the transmission of the RBC is received, the information is used as the front train information and is transmitted to the passing train which is closest to the demarcation point in the jurisdiction range of the RBC and completes the front end screening, as shown in fig. 6.
The invention aims at the condition that the administered RBC is in a transfer RBC working mode, the RBC is subjected to information interaction with a passing train in front, so that the collision between the current train and the train in front is avoided, and the proper distance and the proper braking speed are kept.
Based on any of the above embodiments, if the jurisdictional RBC is a takeover RBC, interacting the rear tracking train operation state information with a handover RBC after operation, including:
determining a rear vehicle demarcation point between the jurisdictional RBC and the transfer RBC after operation;
the domination RBC periodically sends the passing train information which is closest to the rear vehicle boundary point in the current domination range of the domination RBC to the transfer RBC after operation, wherein the passing train information is the finished rear end screening state;
and after receiving rear train information sent by the transfer RBC after the operation, the jurisdiction RBC sends the rear train information to a passing train which is closest to the rear train boundary point in the current jurisdiction range of the jurisdiction RBC, wherein the passing train is in a finished rear end screening state.
Optionally, when the jurisdictional RBC is a takeover RBC, the information related to the train which completes the tail screen and is closest to the boundary point in the jurisdiction range should be periodically sent to the handover RBC, as shown in fig. 7.
Meanwhile, when receiving the relevant information of the passing train sent by the handover RBC, the information is sent as the information of the following train to the passing train which is closest to the demarcation point in the jurisdiction range of the RBC and finishes the rear-end screening, as shown in fig. 8.
The invention aims at the condition that the administered RBC is in the RBC taking-over working mode, the RBC taking-over working mode carries out information interaction with a rear passing train, and the rear train is prevented from rear-end collision with the current train so as to keep proper distance and braking speed.
Based on any of the above embodiments, the current train is a full monitoring mode train.
Without loss of generality, the current train is a train in a complete monitoring mode, so that the RBC can search for trains which can be tracked and traced in front and back according to the current reporting position, the running direction and the interlocking reporting station information of the train, and the train stops querying if the train is out of the administration range of the RBC.
