Description

Automatic generation method for line data of rail transit signal system

Technical Field

The invention belongs to the technical field of rail transit, and particularly relates to a data generation technology.

Background

With the rapid development of urban rail transit and the acceleration of urbanization process, the rail transit construction in China enters the golden development period, about 15 lines are constructed every year according to rail transit plans of various regions, the operation mileage is increased by 400 kilometers, and the total planned rail transit mileage of each region can reach more than 7000 kilometers in predicted 2050 years.

Under the current situation that urban railway lines are increasingly increased, the line data volume becomes huge, the data are manually input in the past, the data volume is huge, a large amount of manual work time is consumed, a large amount of error input is difficult to avoid, even if manual inspection is omitted after configuration is finished, a large amount of time is needed to solve error data existing in a line data configuration table during later-stage system debugging, the configuration data have certain technical requirements on configuration personnel, data configuration modes of subsystems are different, the current data configuration mode is greatly influenced by personnel flow, newly-entered personnel need to carry out data configuration training and are not in accordance with a safety system production mode, once elements in a CAD line single-rail diagram are changed, the data table needs to be modified manually, the problem of partial data table omission caused by manual non-consideration exists, and a large amount of manual labor hours are consumed again for data inspection.

Disclosure of Invention

The invention provides an automatic generation method of track traffic signal system line data, aiming at solving the problems in the prior art and replacing a mode of manually configuring track line data.

Extracting information of trackside elements from a CAD single-track map of the track traffic line, generating basic information tables of all trackside elements according to topological relations among the trackside elements, extracting data in the basic information tables according to the requirements of each subsystem on a line database table, and generating a sub-line database table corresponding to each subsystem.

Furthermore, by taking trackside elements as data and a CAD single-track drawing as a database, screening out required data according to different attributes of each data, and reconfiguring the selected data by adopting C # language to generate a logic object corresponding to the trackside elements.

Further, according to the kilometers of the starting point and the ending point of the virtual section of the line, trackside elements are searched, the topological relation of the trackside elements on the virtual section is established, the logical relation corresponding to the trackside elements is generated, and the basic information table is generated.

Furthermore, according to the line data configuration requirements of subsystems such as ATP, ATO, ZC, CI and ATS, respective data structures are analyzed, corresponding sub-line data tables are respectively generated and combined into a bus line data table.

Compared with the time consumption and the error tendency of manually reading data from a CAD monorail graph, manually calculating logic and manually inputting the data into a form, the method can avoid the error defect of configuration data and quickly, accurately and automatically generate the line data form required by each subsystem.
