Detailed Description
For the purpose of making the objects, technical solutions and advantages of the present invention more apparent, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings, and it is apparent that the described embodiments are some embodiments of the present invention, not all embodiments. 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.
The method and apparatus for detecting the static speed limit of the railway of the present invention will be described with reference to fig. 1 to 4.
The railway static speed limit detection method of the embodiment of the invention can be applied to an urban rail transit system, an inter-urban rail transit system and a general traditional railway system.
The execution body of the railway static speed limit detection method according to the embodiment of the invention can be a processor, and of course, in some embodiments, the execution body can also be a server, and the railway static speed limit detection method according to the embodiment of the invention is described below by taking the processor as the execution body.
As shown in fig. 1, the railway static speed limit detection method according to the embodiment of the invention includes a step 110, a step 120, a step 130, a step 140 and a step 150.
Step 110, determining standard kilometer post sections corresponding to each section of the target line based on link information, incoming and outgoing line information and map information of the target line.
The target line is a railway line for which static speed limit detection is required. The target line is provided with a plurality of kilometers and corresponds to different kilometer scale intervals according to the design line plan.
Because the local change of the line is involved in the actual construction process of the line, a certain deviation exists in the actual line mileage corresponding to the existing kilometer post, when static speed limit detection is carried out, detection is carried out according to the kilometer post section as a reference, and when the detection is carried out according to the existing kilometer post section, a larger error exists between the actual line mileage corresponding to the existing kilometer post section and the mileage data of the actual detection position, so that the detection result is inaccurate.
In this embodiment, in order to avoid the influence of the deviation of the existing kilometer post data on the actual static speed limit detection, it is necessary to correct the kilometer post data having the deviation at different positions and generate standard kilometer post data.
It can be understood that the mileage data corresponding to the standard kilometer post section is consistent with the actual condition of the line.
The link information includes link numbers of each section of the target line and existing kilometer post data corresponding to the link numbers.
The access line information comprises the position of the access line relative to the positive line, corresponding existing kilometer sign data and the length of the access line. The main line is a line for formally putting the train into operation, and the access line is a line for the vehicle section and a line for connecting the vehicle section and the main line. It is understood that the target line includes a positive line and an incoming and outgoing line.
The map information includes the actual longitude and latitude positions corresponding to each link number on the target line, i.e., the actual longitude and latitude positions corresponding to each section of the target line.
In this embodiment, the existing kilometer post data can be corrected based on link information, incoming and outgoing line information and map information to obtain standard kilometer posts divided according to the actual length and position of the target line, and then the standard kilometer post sections corresponding to the sections of the target line are determined.
And 120, determining a first speed limit value corresponding to a plurality of standard kilometer scale intervals based on curve information, ramp information, track intersection information and turnout information of the target line.
The curve information includes at least the actual position of the curve on the target road, the design speed limit value of the curve, and specific parameters of the curve, and the specific parameters of the curve include at least the length, curvature, and other information of the curve.
The ramp information at least comprises the actual position of the ramp on the target road, the design speed limit value of the ramp and specific parameters of the ramp, and the specific parameters of the ramp at least comprise the information such as the length and the gradient of the ramp.
The track intersection information at least comprises a left line and a right line corresponding to the track intersection, the actual position of the track intersection and a design speed limit value corresponding to the track intersection.
It can be understood that the target line is configured with a curve superhigh speed limit table after the design is completed, and the curve superhigh speed limit table comprises curve information, ramp information and track intersection information. In the present embodiment, the curve information, the ramp information, and the track intersection information of the target line can be extracted by reading the curve superhigh speed limit table.
The turnout information at least comprises the name, the actual position and the design speed limit value corresponding to turnouts with different names in the target line. In this embodiment, the speed limit value corresponding to the switch can be determined by reading the name of the switch.
In other embodiments, different switch types correspond to different speed limit values in design, and the design speed limit value corresponding to the switch can be determined by reading the switch type.
The station information includes the actual position of the station and the corresponding speed limit value.
In some embodiments, considering the speed limit requirement of the platform, the first speed limit value corresponding to the standard kilometer post sections can be determined based on curve information, ramp information, track intersection information, turnout information and platform information of the target line.
It can be understood that standard kilometer post sections respectively corresponding to the curve, the ramp, the rail intersection point, the turnout and the platform on the map can be determined according to the actual positions of the curve, the ramp, the rail intersection point, the turnout and the platform.
In some embodiments, after the standard kilometer post sections are determined, the first speed limit value of the standard kilometer post section may be determined according to the design speed limit value corresponding to the curve, the ramp, the track intersection, the switch and the platform in each standard kilometer post section.
When only one of a curve, a ramp, a rail intersection, a turnout and a platform exists in the standard kilometer distance, for example, when only the ramp exists in the standard kilometer distance A, the design speed limit value corresponding to the ramp is used as the first speed limit value of the standard kilometer distance A.
And under the condition that a plurality of curves, ramps, rail intersections, turnouts and platforms exist in the standard kilometer range, determining a plurality of sub speed limit values corresponding to the curves, the ramps, the rail intersections, the turnouts and the platforms respectively, and determining the smallest one of the plurality of sub speed limit values as a first speed limit value.
For example, when there are curves, slopes and track intersections in the standard kilometer post section a, a first sub-speed limit value, a second sub-speed limit value and a third sub-speed limit value corresponding to the curves, slopes and track intersections are respectively determined, and then the smallest one of the first sub-speed limit value, the second sub-speed limit value and the third sub-speed limit value is determined as the first speed limit value of the standard kilometer post section.
It can be understood that a plurality of sub speed limit values corresponding to the standard kilometer section can be determined, the plurality of sub speed limit values are speed limit values determined based on curve information, ramp information, track intersection information, turnout information and platform information respectively, and the minimum one of the plurality of sub speed limit values is determined as a first speed limit value.
In this embodiment, by fully considering curve information, ramp information, track intersection information, switch information and platform information on the target line, an accurate speed limit value of a line design that is more attached to the target line can be determined, and further accuracy in the subsequent static speed limit detection is ensured.
In other embodiments, when any one of a curve, a ramp, a track crossing, a switch, and a platform does not exist in the standard kilometer post section, the upper limit of the train running speed on the whole target line may be regarded as the first speed limit value of the standard kilometer post section.
And 130, determining a second speed limit value of the target train on the target line based on the train length, the reverse guard distance and the reverse guard speed of the target train.
The target train is a train running on the target line. Under the conditions of starting acceleration, braking, sliding and the like, the target train needs to consider the retrogressive protection distance and the retrogressive protection speed. When there are other target trains on the target line, a certain safety distance needs to be satisfied between the plurality of trains.
In this embodiment, when the target trains run according to the second speed limit value, safety braking can be achieved at the required reverse protection distance and reverse protection speed, and the safety distance between the two target trains can be ensured.
It can be appreciated that the safe running speed of the target train can be determined according to the train length and the reverse guard distance of the target train. In the case where the target train is operated at a safe traveling speed, the target train can maintain a safe distance from another target train after braking is performed.
The safe running speed may be a speed limit value calculated according to the reverse guard distance and the train length, or may be a reverse guard speed of the target train, and the safe running speed may be used as a second speed limit value of the target line.
It can be understood that when the safe running speed is determined according to the related parameters of the train, the calculation function of the safe running speed can be preconfigured according to different target trains, and the safe running speed of the target train can be automatically generated after the train length and the retrogressive protection distance of the target train are obtained.
And 140, determining the smaller one of the first speed limit value and the second speed limit value as a target speed limit value of the standard kilometer section.
It is understood that the first speed limit is a speed limit determined based on the design requirements of the curve, ramp, rail intersection, switch and platform of the target line.
The second speed limit value is a speed limit value required for the target train to actually run on the target road for maintaining a safe distance.
And comparing the first speed limit value with the second speed limit value, and determining the smaller speed limit value as a target speed limit value of the standard kilometer interval. In this case, the design requirement and the actual operation requirement of the target line can be comprehensively considered.
And 150, determining the actual speed limit value of the standard kilometer post section as non-compliance under the condition that the actual speed limit value of the standard kilometer post section is larger than the target speed limit value.
The actual speed limit value is a speed limit value calculated according to the actual running state of the train on the target line or an actual speed limit value manually measured by a worker.
When detecting, detecting according to the section of the target line corresponding to the standard kilometer post section.
The target speed limit value is a speed limit value determined according to the design requirement of the target line and the safety requirement to be considered in the actual operation of the target line in a laboratory environment.
And under the condition that the actual speed limit value of the standard kilometer scale interval is smaller than or equal to the target speed limit value, the actual speed limit value of the standard kilometer scale interval is compliant.
And under the condition that the actual speed limit value of the standard kilometer post section is larger than the target speed limit value, the actual speed limit value of the standard kilometer post section is not compliant. In this case, the running speed of the target train in the standard kilometer post section of the target line may be greater than the target speed limit value, so that potential safety hazards exist.
In this embodiment, link information, incoming and outgoing line information, and map information of a target line are processed, so that kilometer sign information having errors is divided from the link information and the incoming and outgoing line information, and kilometer sign information having deviations from actual conditions of the target line is corrected, a standard kilometer sign section of the target line is obtained, and deviations of the target line section during detection are corrected.
When a target speed limit value is determined, a first speed limit value of a line design level is determined according to the requirements of speed limit in curve information, ramp information, track intersection information and turnout information; and determining a second speed limit value on the actual driving safety level according to the train length, the reverse protection distance and the reverse protection speed of the target train. In the embodiment, the target speed limit value is more accurate by comprehensively considering the design requirement of the target line and the actual driving safety requirement of the target train, so that the accuracy of the detection result is improved.
According to the railway static speed limit detection method provided by the embodiment of the invention, the standard kilometer post section is determined, the target line section for static speed limit detection is corrected, the design requirement of the target line and the driving safety requirement are comprehensively considered, and the accuracy of the static speed limit detection result is ensured.
In some embodiments, as shown in FIG. 2, step 110: based on link information, incoming and outgoing line information and map information of the target line, a standard kilometer post section corresponding to each section of the target line is determined, including step 121 and step 122.
Step 121, determining the actual positions of the broken links and the incoming and outgoing lines on the target line based on link information, incoming and outgoing line information and map information.
It should be noted that, because the broken link includes the phenomenon that the kilometer sign numbers are not connected due to local rerouting or segment measurement, the actual position of the broken link needs to be determined according to the existing kilometer sign data in link information and map information, so as to determine the standard kilometer sign section where the broken link is located.
Because the kilometer sign data of the in-out line position is not connected with the kilometer sign data on the positive line, the existing kilometer sign data corresponding to the in-out line is determined according to the actual position of the in-out line, the length of the in-out line and link information at the in-out line, and then the existing kilometer sign data is combined with the length, the position and map information of the in-out line to further obtain a standard kilometer sign section corresponding to the in-out line.
And 122, determining standard kilometer post sections corresponding to the broken links and the incoming and outgoing lines respectively based on the actual positions.
After the actual positions of the broken links and the incoming and outgoing lines are determined, the standard kilometer sign sections corresponding to the broken links and the incoming and outgoing lines are determined in the standard kilometer sign sections divided in the map information.
According to the railway static speed limit detection method provided by the embodiment of the invention, the correction of the kilometer sign data of the section corresponding to the broken link and the incoming line of the target line is realized by determining the inaccurate broken link of the kilometer sign data and the actual position of the incoming line, so that the accuracy of the detection result is ensured.
In some embodiments, determining a second speed limit value for the target train at a second speed limit value of the target line for a plurality of standard kilometer scale intervals based on the train length, the back-off protection distance, and the back-off protection speed of the target train includes: and determining a theoretical running speed limit value of the target train based on the train length and the retrogressive protection distance.
The retrogression protection speed is the safety speed of the target train under the condition of retrogression in the running process, and is the retrogression speed limit value required by the target train when the route is designed.
It will be appreciated that the theoretical operating speed limit is a speed limit calculated from the reverse run distance and the train length.
In the present embodiment, the smaller one of the theoretical running speed limit value and the reverse run protection speed may be determined as the second speed limit value. Under the condition, the requirement of the target line on the reverse protection speed of the target train design and the requirement of the target train on the speed limit in the actual running process of the target line can be comprehensively considered, the complex condition of the target train in the actual running process can be more comprehensively considered, and the rationality of the second speed limit value setting is ensured.
In other embodiments, before determining the smaller one of the first speed limit value and the second speed limit value as the target speed limit value of the standard kilometer section, the method for detecting the static speed limit of the railway according to the embodiment of the invention further includes generating road condition information of the target line based on curve information and ramp information.
It is understood that the curve information includes specific parameters of the curve, and the specific parameters of the curve include at least information such as a length, a track inclination angle, and a curvature of the curve.
The ramp information includes specific parameters of the ramp including at least a length of the ramp and a grade of the ramp.
According to the actual conditions of the curve and the ramp of the standard kilometer scale section, the road condition information corresponding to the running of the target train can be determined, and the road condition information comprises the information such as the curvature of the curve on the running section of the train, the inclination angle of the track in the curve, the gradient and the like. The road condition information may affect the safe distance required by the target train when starting and braking.
When the actual running speed limit value of the target train is calculated, road condition information, the length of the train and the reverse protection distance are comprehensively considered, influence factors corresponding to the ramp and the curve are added in the function of calculating the actual running speed limit value, the more accurate actual running speed limit value of the target train in the target standard kilometer scale zone can be determined, and then the smaller one of the actual running speed limit value and the reverse protection speed is determined as the second speed limit value.
It is understood that the target standard kilometer post section is a standard kilometer post section including at least one road condition of a curve and a ramp.
According to the railway static speed limit detection method provided by the embodiment of the invention, the influence of the ramp and the road condition of the curve on the driving speed of the target train is considered, so that the more accurate safe driving speed of the target train in the corresponding target kilometer scale interval can be obtained, and further, the more accurate second speed limit value is determined, thereby improving the accuracy of static speed limit detection.
In some embodiments, before determining that the actual speed limit value of the standard kilometer post section is not compliant in the case that the actual speed limit value of the standard kilometer post section is greater than the target speed limit value, the method for detecting the static speed limit of the railway according to the embodiment of the invention further includes determining a detection direction of the target line based on the line direction information.
It can be understood that the directions of the line sections in the line direction information are not uniform, the starting point and the end point of the standard kilometer post section can be determined first, the starting point of the standard kilometer post section is taken as a reference, the running directions of the left line and the right line of different sections in the target line are unified, and one direction is selected as the detection direction.
After the detection direction is determined, comparing the actual speed limit values of the standard kilometer post sections with the target speed limit values in sequence according to the detection direction.
According to the railway static speed limit detection method provided by the embodiment of the invention, the static speed limit detection is carried out on the target line according to the determined unified detection direction, so that the detection sequence of a plurality of target kilometer post sections in detection can not be disordered, and the accuracy of the detection result is ensured.
