Research And Implementation Of The Assistant System Of Design For The Ground Facility Of CTCS-2

CTCS-2 is a key system of the speed-raised main line and passenger special line of China,it is a new technology of railway signal in our country.The design for project of signal of the system has changed more compared to the traditional system of railway signal,many new contents have added to it such as the predigestion of the slope of line,the combination of the speed of line,the lay of section frequency and the design for vertical drawing of line,both the difficulty of design and the workload have increased more.A assistant system of design for the ground facility of CTCS-2 which is based on the computer was studyed in this paper.The system has changed the traditional working which mainly rely on men and overcomed lots of problems such as the low efficiency and quality of the design for project of signal of CTCS-2 now. It can complete the design for project of ground signal system of the existing line which raised to 200km/h and new passenger special line automatically and intelligently,it also can improve the efficiency and quality of the design for project of signal greatly.The paper analyzed the demand of the system,explained the background and significance of studying of the system, the civil and oversea actuality was described;According to the total demand of the system and the corresponding requirement of each module,it analyzed the total framework of the system, the design for pretreatment module,the design for user table module,the design for project drawing module and the design for system interface module in term of the idea of software engineering, the software design of system was also produced;This paper described the detail design method of the paimary function modules of the system which consists of pretreatment module, predigestion of the slope of line module,combination of the speed of line module, the lay of section frequency module,vertical drawing of line module and statistic of project number module; At last, both the interface and the flow of operation were introduced..
