Detailed Description
The following description of the embodiments of the present invention will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the invention. All other embodiments, which can be made by those skilled in the art based on the embodiments of the present invention without making any inventive effort, shall fall within the scope of the present invention.
The signal system uniformly divides the line attributes in the system design process, and makes corresponding division rules so as to improve the efficiency and quality of system design and data configuration and facilitate the centralized retrieval of the data information by the system functional software.
As shown in fig. 1, a method for dividing civil engineering properties of a track traffic line, where a signal system uniformly divides the track traffic line properties according to a division principle, where the division basis includes:
(1) Dividing according to the condition that the road sections are affected by weather;
(2) Dividing according to the civil environment attribute of the line section;
(3) Dividing according to whether isolation protection is carried out between two track lines of the double-line section;
(4) Dividing according to the evacuation conditions of the route sections.
Dividing according to the condition that a line section is affected by weather, wherein the line section comprises an underground section and an overground section, the underground section is in the line range of the underground section, and a subway train runs on the underground line and is not affected by rain and snow weather; the ground section comprises an open section, a ground section and an elevated section, and in the range of the ground section, the subway train runs on the ground section and is influenced by rain and snow weather.
The method comprises the steps of dividing according to civil environment attributes of line sections, wherein the civil environment attributes comprise a single line section and a double line section: the single-line road section is that only one track line exists in a civil environment of a train running road section range in the road section area; the double-track section is that two or more track lines exist in a civil environment of a train running section range in the section area.
Dividing according to whether isolation protection is carried out between two track lines of a double-line section, wherein the two track lines comprise an isolated section and a non-isolated section, and the isolated line section is used for carrying out the isolation protection between each track line in the range of a train running section in the area; the non-isolated line section is that the isolation protection is not carried out among all the track lines in the range of the train running section in the area.
As shown in fig. 2, the station area where safety isolation is performed between two lines on a side station is divided into sections with isolation, the section where safety isolation is not performed between two lines on the upper and lower lines and the station area are divided into sections without isolation, and when the inter-station area is a single-hole double-line or the safety isolation of sufficient strength is provided between two tracks of a ground and overhead double-line section, these areas are divided into single-line sections.
Dividing the route sections according to the evacuation conditions of the route sections, wherein the route sections comprise no evacuation platform, a route left evacuation platform, a route right evacuation platform and double-side evacuation platforms.
For a route section divided by weather-affected properties of the route section, if the length of the above-ground section or the below-ground section is smaller than the length of the longest train running on the route, it is not necessary to define one section separately due to the weather properties. As shown in fig. 3, when the length of a tunnel, an underground section, a road surface or an overhead of a civil environment is less than the maximum train length running on a route, the short road section is not separately divided into one underground road section or an above-ground road section, but may be divided into two sides of the above-ground road section or the underground road section.
For road sections divided according to different evacuation conditions, the length of the road section is not required to be longer than the length of the vehicle. As shown in fig. 4, when road section division is performed according to the difference of evacuation conditions, the road section length is not required to be considered. Even when the section length of one evacuation platform characteristic is smaller than the maximum train length of the route, it is allowed to be divided into sections of one evacuation characteristic alone, but the sections are either underground sections or above-ground sections together with adjacent sections.
The route section boundaries are defined according to the following principle:
(1) At CBTC region and non-CBTC region boundaries;
(2) A line terminal;
(3) And the mileage position of the four civil environment attributes on the line.
As shown in fig. 1, the definition of the road section boundary on the line is mainly divided according to the change of the line civil engineering environment attribute, and the factors of line terminals, CBTC area and non-CBTC area boundaries, other line boundaries and the like are considered. The road sections of the section mainly comprise ground and underground road sections, single-line and double-line road sections and road sections of different evacuation platform positions, and can also comprise road sections with safety isolation properties. For a two-wire and isolated road segment, whether to divide into single-wire road segments is considered in terms of its isolation strength.
When the road sections are divided according to the weather-affected attribute of the road sections, the positions of boundary points of the road sections on the ground and the underground are defined to extend a certain distance from the actual boundary mileage position of the tunnel and the ground to the tunnel direction. As shown in fig. 5, when the above-ground link and the below-ground link are defined at the ground-tunnel boundary, the link boundary is defined on the tunnel side and is disposed at a position apart from the tunnel boundary by more than the sum of the maximum vehicle length and the positioning error. Because the emergency braking assurance rates of the train are different between the on-ground road section and the underground road section by the vehicle-mounted signal system, the on-ground road section adopts a larger emergency braking assurance rate, so that the arrangement of the road section boundaries ensures that trains in different directions adopt lower parking assurance rates on the on-ground road section.
If the evacuation conditions of the platform track section are different from those of the adjacent tracks, the arrangement of the section boundary points with different evacuation conditions should ensure that the train can be evacuated with doors leading to the platform when the train does not enter or leave the platform section area completely. As shown in fig. 6, when the first door of the head or tail of the train is aligned with the first door of the platform, the range of the interval where the other end of the train is located is configured as the same evacuation section as the platform, allowing passengers to be evacuated to the platform.
The above description of the method embodiments further describes the solution of the present invention by means of device embodiments.
The invention also provides a device for dividing the civil engineering property data of the track traffic line, which uniformly divides the track traffic line property information according to a dividing principle, and specifically comprises the following steps:
the first dividing unit is used for dividing the signal system according to the condition that the line section is affected by weather;
the second dividing unit is used for dividing the signal system according to the civil environment attribute of the line section;
the third dividing unit is used for dividing the signal system according to whether the two track lines of the double-line section are isolated and protected;
and the fourth dividing unit is used for dividing the signal system according to the evacuation conditions of the line sections.
It will be clear to those skilled in the art that, for convenience and brevity of description, specific working procedures of the described modules may refer to corresponding procedures in the foregoing method embodiments, which are not described herein again.
While the invention has been described with reference to certain preferred embodiments, it will be understood by those skilled in the art that various changes and substitutions of equivalents may be made and equivalents will be apparent to those skilled in the art without departing from the scope of the invention. Therefore, the protection scope of the invention is subject to the protection scope of the claims.
