Automatic Generation Of Interlocking Outdoor Cable Path Diagram

In the development of Chinese high-speed railway,railway signal play a vital role.In terms of railway signals,computer interlocking system is an indispensable guarantee equipment for the efficient operation of train in the station.In order to make the construction personnel have a clearer understanding of the construction details required during the construction of the station computer interlocking system,the station computer interlocking engineering drawing is usually drawn before construction.Among the engineering drawings,the design of the outdoor cable path diagram is tedious at work and large in the number of drawings,which is one of the difficulties in signal engineering design.In order to improve the drawing efficiency of outdoor cable route path,according to the characteristics of the drawing,this thesis design a software which can automatically generate the outdoor cable path diagram and corresponding outdoor cable wiring diagram and outdoor network diagram.Based on C# programming language and combined with the theoretical knowledge of station signal layout plane engineering design and outdoor cable path diagram,this thesis optimizes A* search algorithms combined with the specificity of outdoor cable wiring,to realize automatic generation of outdoor cable path diagram and outdoor cable wiring diagram and outdoor network diagram for different station.First,based on the data of station signal layout plane,the static of display of station signal layout plane is realized by reading data from Excel.In addition to necessary data for station signal layout plane,the Excel also includes the standard data for automatic wiring,such as the spare quantity of signal cable core wires,the corresponding relationship between the number of the switch diagram and switch machine which is specified in the engineering design specification.Secondly,the generation and layout of cable network connection equipment is based on previous data.This part can be divided into feeding/receiving end module,signal box module,switch machine module,and distributing terminal board module.After preliminary layout plan generated from data processing in the early stage,the plan has to be confirmed and adjusted through human-computer interaction because of the complex application scenario.The data of feeding/receiving end module,signal box module,switch machine module can be adjusted through the configuration table.Distributing terminal board module generates and displays the preliminary layout plan on the interface,and the user can manually drag it to a reasonable position through the interface.In order to distinguish the terminal equipment connected with the distributing terminal board,all terminal equipment is connected with the distributing terminal board by a straight line.Finally,according to the location of the cable network connection equipment,the existing drawing according to the wiring requirement,we can use appropriate algorithms for automatic wiring.While viewing the outdoor cable path diagram,we can also view the corresponding outdoor cable network diagram and the outdoor cable wiring diagram.The automatic generation of interlocking outdoor cable path diagram improves the efficiency of the early design stage of the station interlocking to a certain extent,making the originally tedious work simple and esay to understand.This can free the engineering designers from repetitive and compicated drawing,improving the work condition of the engineering designers.It can also avoid mistakes caused by manual drawing at all stages,which can greatly reduce the number of later reworks.
