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.
The method and the device for detecting the static speed limit of the railway are described in the following with reference to fig. 1-4.
The railway static speed limit detection method provided by the embodiment of the invention can be applied to an urban rail transit system, an intercity rail transit system and a general traditional railway system.
The executing main body of the railway static speed limit detection method of the embodiment of the invention can be a processor, certainly, in some embodiments, the executing main body can also be a server, and the railway static speed limit detection method of the embodiment of the invention is described below by taking the processor as the executing main body.
As shown in fig. 1, the method for detecting a static speed limit of a railway according to an embodiment of the present invention includes steps 110, 120, 130, 140 and 150.
And step 110, determining a standard kilometer post section 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 track is a railway track on which static speed limit detection is required. The target line is provided with a plurality of kilometer posts according to the design line plan and corresponds to different kilometer post intervals.
Because the local change of the line is involved in the actual building process of the line, the actual line mileage corresponding to the existing kilometer post has certain deviation, when static speed limit detection is carried out, detection needs to be carried out according to a kilometer post interval as a reference, and when the static speed limit detection is carried out according to the existing kilometer post interval, a large error exists between the actual speed limit detection and the mileage data of an actual detection position, so that the detection result is inaccurate.
In this embodiment, in order to avoid the influence of the deviation of the conventional kilometer sign data on the actual static speed limit detection, the kilometer sign data with the deviation at different positions needs to be corrected and standard kilometer sign data needs to be generated.
It can be understood that the mileage data corresponding to the standard kilometer scale interval is consistent with the actual condition of the line.
It should be noted that the link information includes the link numbers of the respective segments of the target line and the existing kilometer sign data corresponding to the link numbers.
The incoming and outgoing line information comprises the position of the incoming and outgoing line relative to the main line, corresponding existing kilometer sign data and the length of the incoming and outgoing line. The main line is a line on which the train is put into operation, and the entrance and exit lines are a train section line and a line connecting the train section and the main line. It will be understood that the target line includes a positive line as well as an incoming and outgoing line.
The map information includes actual longitude and latitude positions corresponding to the link numbers on the target line, that is, actual longitude and latitude positions corresponding to the sections of the target line.
In this embodiment, based on the link information, the incoming and outgoing line information, and the map information, the existing kilometer sign data can be corrected to obtain standard kilometers signs divided according to the actual length and position of the target line, and then the standard kilometer sign sections corresponding to the sections of the target line are determined.
And step 120, determining first speed limit values corresponding to a plurality of standard kilometer post sections based on the curve information, the ramp information, the track intersection point information and the turnout information of the target line.
It should be noted that the curve information at least includes an actual position of the curve on the target line, a design speed limit value of the curve, and specific parameters of the curve, and the specific parameters of the curve at least include information such as a length and a curvature of the curve.
The ramp information at least comprises the actual position of the ramp on the target line, the design speed limit value of the ramp and the specific parameters of the ramp, and the specific parameters of the ramp at least comprise the length, the gradient and other information of the ramp.
The track intersection point information at least comprises a left line and a right line corresponding to the track intersection point, the actual position of the track intersection point and the corresponding design speed limit value at the track intersection point.
It can be understood that the target line is configured with a curved superordinate speed limit table after the design is completed, and the curved superordinate speed limit table includes the above-mentioned curve information, ramp information, and track intersection information. In the present embodiment, the curve information, the slope information, and the track intersection information of the target link can be extracted by reading the curve superordinate speed limit table.
The turnout information at least comprises the name and the actual position of the turnout in the target line and the design speed limit value corresponding to the turnout with different names. In the present embodiment, the speed limit value corresponding to a switch can be determined by reading the name of the switch.
In other embodiments, different switch types correspond to different speed limit values during design, and the design speed limit value corresponding to the switch can be determined by reading the switch types.
The station information includes the actual position of the station and the corresponding speed limit.
In some embodiments, the first speed limit values corresponding to the standard kilometer post sections can be further determined based on the curve information, the ramp information, the track intersection information, the turnout information and the platform information of the target line in consideration of the speed limit requirement of the platform.
It can be understood that the standard kilometer post sections respectively corresponding to the curve, the ramp, the track intersection, the turnout and the platform on the map can be determined according to the actual positions of the curve, the ramp, the track intersection, the turnout and the platform.
In some embodiments, after the standard kilometer post sections are determined, the first speed limit value of each standard kilometer post section may be determined according to the design speed limit values respectively corresponding to the corresponding curve, ramp, track intersection, switch and platform in each standard kilometer post section.
And under the condition that only one of a curve, a ramp, a track intersection, a turnout and a platform exists in the standard kilometer section, for example, under the condition that only the ramp exists in the standard kilometer section A, taking the design speed limit value corresponding to the ramp as the first speed limit value of the standard kilometer section A.
Under the condition that a plurality of curves, ramps, track intersections, turnouts and platforms exist in a standard kilometer section, a plurality of sub speed limit values corresponding to the curves, the ramps, the track intersections, the turnouts and the platforms are respectively determined, and the minimum one of the sub speed limit values is determined as a first speed limit value.
For example, when a curve, a ramp and a track intersection exist 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 curve, the ramp and the track intersection 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 sub speed limit values are determined respectively based on the curve information, the ramp information, the track intersection information, the turnout information and the platform information, and then the minimum one of the sub speed limit values is determined as the first speed limit value.
In the embodiment, the accurate speed limit value of the target line more fitting to the line design can be determined by fully considering the curve information, the ramp information, the track intersection point information, the turnout information and the platform information on the target line, and the accuracy of the subsequent static speed limit detection is further ensured.
In other embodiments, when any one of a curve, a ramp, a track intersection, a switch and a platform does not exist in the standard kilometer post section, the upper limit of the train operation speed on the entire target line may be used as the first speed limit value of the standard kilometer post section.
And step 130, determining a second speed limit value of the target train on the target line based on the train length, the retrograde protection distance and the retrograde protection speed of the target train.
The target train is a train that runs on the target route. The target train needs to consider the retrograde protection distance and retrograde protection speed in the states of starting acceleration, braking, sliding and the like. When other target trains exist on the target line, a certain safety distance needs to be met among the plurality of trains.
In the embodiment, when the target train operates according to the second speed limit value, the safety braking can be realized at the required retrogression protection distance and retrogression protection speed, and the safety distance between the two target trains can be ensured.
It can be understood that the safe driving speed of the target train can be determined according to the train length and the retrograde protection distance of the target train. In the case where the target train is operated at a safe running speed, the target train can maintain a safe distance from another target train after braking.
The safe driving speed can be a speed limit value calculated according to the retrogression protection distance and the train length, can also be the retrogression protection speed of the target train, and can 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 relevant parameters of the train, the calculation function of the safe running speed can be configured in advance according to different target trains, and after the train length and the degenerative protection distance of the target train are obtained, the safe running speed of the target train can be automatically generated.
And step 140, determining the smaller one of the first speed limit value and the second speed limit value as a target speed limit value of a standard kilometer interval.
It is understood that the first speed limit value is a speed limit value determined based on design requirements of a curve, a ramp, a track intersection, a switch, and a platform of the target line.
The second speed limit value is the speed limit value required by the target train to keep the safe distance in the actual operation on the target line.
And comparing the first speed limit value with the second speed limit value, and determining the smaller one of the first speed limit value and the second speed limit value as a target speed limit value of a standard kilometer interval. In this case, the design requirements and actual operating requirements of the target line may be taken into account.
And 150, determining the actual speed limit value of the standard kilometer section as not compliant under the condition that the actual speed limit value of the standard kilometer section is greater than the target speed limit value.
It should be noted that the actual speed limit value is a speed limit value calculated on the target line according to the actual running state of the train or an actual speed limit value manually measured by a worker.
When the detection is performed, the detection is performed according to the section of the target line corresponding to the standard kilometer scale section.
The target speed limit value is 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 the laboratory environment.
And under the condition that the actual speed limit value of the standard kilometer section is less than or equal to the target speed limit value, the actual speed limit value of the standard kilometer section is in compliance.
And under the condition that the actual speed limit value of the standard kilometer section is greater than the target speed limit value, the actual speed limit value of the standard kilometer section is not in compliance. Under the condition, 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, and further potential safety hazards exist.
In the present embodiment, by processing the link information, the incoming and outgoing line information, and the map information of the target link, the kilometer sign information with errors is divided into the link information and the incoming and outgoing line information, and the kilometer sign information with deviations from the actual conditions of the target link is corrected to obtain the standard kilometer sign sections of the target link, and the deviations of the target link sections during detection are corrected.
When a target speed limit value is determined, a first speed limit value on a line design level is determined according to the requirements of speed limit in curve information, ramp information, track intersection point information and turnout information; and determining a second speed limit value at the actual driving safety level according to the train length, the retrogression protection distance and the retrogression protection speed of the target train. In the embodiment, the target speed limit value is more accurate by comprehensively considering the target line design requirement 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 accuracy of the static speed limit detection result is ensured by determining the standard kilometer post section, correcting the target line section for static speed limit detection and comprehensively considering the design requirement and driving safety requirement of the target line.
In some embodiments, as shown in FIG. 2, step 110: and determining a standard kilometer post section corresponding to each section of the target line based on the link information, the entrance and exit line information and the map information of the target line, wherein the steps include step 121 and step 122.
And step 121, determining the actual positions of the broken link and the incoming and outgoing line on the target line based on the link information, the incoming and outgoing line information and the 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 line change or sectional measurement, the actual position of the broken link needs to be determined according to the existing kilometer sign data and map information in the link information, and then the standard kilometer sign interval of the position where the broken link is located is determined.
Because the kilometer post data of the position of the incoming and outgoing line is not connected with the kilometer post data on the main line, the existing kilometer post data corresponding to the incoming and outgoing line is determined according to the actual position of the incoming and outgoing line, the length of the incoming and outgoing line and the link information of the incoming and outgoing line, and then the existing kilometer post data is combined with the length, the position and the map information of the incoming and outgoing line, so that the standard kilometer post section corresponding to the incoming and outgoing line is obtained.
And step 122, determining standard kilometer post intervals corresponding to broken chains and incoming and outgoing lines respectively based on the actual positions.
And after the actual positions of the broken chain and the line are determined, determining a standard kilometer post section corresponding to the broken chain and the line in and out in the standard kilometer post sections divided in the map information.
According to the static speed limit detection method for the railway, disclosed by the embodiment of the invention, the correction of the kilometer post data on the sections corresponding to the broken link and the incoming and outgoing lines of the target line is realized by determining the actual positions of the broken link and the incoming and outgoing lines of inaccurate kilometer post data, so that the accuracy of the detection result is further ensured.
In some embodiments, determining a second speed limit value of the target train at the target line based on the train length, the degenerative protection distance and the degenerative protection speed of the target train and corresponding to a plurality of standard kilometer post sections comprises: and determining the theoretical operation speed limit value of the target train based on the train length and the retrogression protection distance.
The retrograde protection speed is a safe speed of the target train under the condition of retrograde generation in the running process, and is a retrograde speed limit value required by the target train during the line design.
It is understood that the theoretical operation speed limit is a speed limit calculated based on the distance of the retrograde protection and the length of the train.
In this embodiment, the smaller one of the theoretical operation speed limit and the retrograde protection speed may be determined as the second speed limit. Under the condition, the requirement of the target line on the retrograde protection speed of the target train and the requirement of the target train on the speed limit in the actual running process of the target train on 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 reasonability of the setting of the second speed limit value 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 in the standard kilometer section, the method for detecting a static speed limit of a railway according to the embodiments of the present invention further includes generating road condition information of a target route based on the curve information and the ramp information.
It can be understood that the curve information includes specific parameters of the curve, and the specific parameters of the curve at least include information such as the length of the curve, the inclination angle of the track, and the curvature.
The ramp information comprises specific parameters of the ramp, and the specific parameters of the ramp at least comprise the length and the gradient of the ramp.
According to the actual conditions of the curve and the ramp in the standard kilometer post section, the road condition information corresponding to the running of the target train can be determined, and the road condition information comprises information such as curvature of the curve on the running section of the train, inclination angle and gradient of a track in the curve and the like. The road condition information affects the safety distance required by the target train during starting and braking.
When the actual operation speed limit value of the target train is calculated, the road condition information, the train length and the retrograde protection distance are comprehensively considered, the influence factors corresponding to the ramp and the bend are added in the function of calculating the actual operation speed limit value, the more accurate actual operation speed limit value of the target train in the target standard kilometer post section can be determined, and then the smaller one of the actual operation speed limit value and the retrograde 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 of a curve and a slope.
According to the method for detecting the static speed limit of the railway, disclosed by the embodiment of the invention, the influence of the road conditions of the ramp and 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 section can be obtained, and the more accurate second speed limit value can be further determined, and the accuracy of static speed limit detection is improved.
In some embodiments, in a case that the actual speed limit value of the standard kilometer section is greater than the target speed limit value, before determining that the actual speed limit value of the standard kilometer section is not compliant, the method for detecting static speed limit of a railway of an embodiment of the present invention further includes determining a detection direction of the target route based on the route direction information.
It can be understood that, the directions of the line segments in the line direction information are not uniform, the start point and the end point of the standard kilometer sign interval can be determined first, the running directions of the left line and the right line of different intervals in the target line are unified by taking the start point of the standard kilometer sign interval as a reference, and one of the directions is selected as the detection direction.
And after the detection direction is determined, comparing the actual speed limit values of the plurality of standard kilometer post intervals with the target speed limit value 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 the detection process can be ensured not to be disordered, and the accuracy of the detection result is ensured.
