Research On Automatic Generation Of AutoCAD Drawings Based On CSM

Centralized Signaling Monitoring system has played an increasingly important role in practical application.The management level of railway signal equipment has played an important role in ensuring the safety product and transport.Construction drawings which based on the Centralized Signaling Monitoring system,it also plays an important role to guide the railway site construction personnel to complete the wiring design,security investigation,an important means of data organization.With the continuous improvement of the national railways,more and more station construction is highly used in the actual production.It puts forward to higher and higher requirements due to the extensive need for rapid efficient and standardized accurate construction of the station construction drawings.It is difficult to meet the needs of practical application,and the automated drawing system of AutoCAD drawing has become a hotspot in this field.In view of the practical problems of the low efficiency of the drawings faced by the large amount of data from differ modules in the Centralized Signaling Monitoring system,this paper presents a method of automatic generation of AutoCAD drawings based on CSM,and some detailed data processing rules and drawing automatic generation process are given next by.The main contents are as follows.Firstly,a complete set of data organization and processing rules are proposed for the specific data problem of CSM.The concept of data definition and segment definition is introduced,and its concrete explanation is given.On this basis,it gives the design of different rules for detailed,which is used to expound the practical application in the specific operation,and illustrate the accuracy and the speed in different data modules.Secondly,some operation and process in AutoCAD drawings automated generation system is introduced.And then this paper gives the secondary development of AutoCAD drawings of various types of operations for the accurate and rapid generation of drawings,the premise of generating drawings analysis are given.Including the preparation and detailed instructions,and some explanations for which role it played in the production of the AutoCAD drawings.The general process of automatic drawing of AutoCAD drawingsbased on CSM is given,and the general drawing of the station and the production of the single drawing are described in detail,and the convenience and efficiency of the automatic drawing system of AutoCAD drawings based on CSM are fully explained.Finally,the design of system and structure are given,and the function explanation of each part of the system is given,which explains its great effect in practical application.The functions and operation examples of each part of the system are introduced respectively.And then it shows the concrete operation of the automatic drawing system of AutoCAD drawing based on CSM,and giving the analyze of result in detail.The comparison between the region query and the k-nearest neighbor query is carried out.The experimental results show the good performance of the 3D Grid-R tree hybrid index structure in the query method.On this basis,compared with the traditional manual drawing drawings and analysis,it shows that AutoCAD drawing automation system which based on CSM has good performance and great advantages in the practical application.
