Analysis of Invention Patents Related to Testing Technologies for Communication Based Train Control System Applied by Thales SEC Transport Company

Communication-based train control (CBTC) has become the main technical format of urban rail transit signal system. All kinds of software and hardware control logic in CBTC system need to follow the mechanism of rail transit train operation and meet the fail-safe principle. The research, development and test process of CBTC system should not only take the realization of software and hardware functions, but also take the realization of safety-critical principles into consideration. Analyzing relevant invention patents of representative enterprises with certain technical strength can help practitioners to better understand the test process and test technology involved in CBTC system. By considering that Thales Shanghai Electric Group Company (SEC) Transport is a signal system design, research and development enterprise with a large market share in China, this paper takes the relevant invention patents applied by Thales SEC Transport in testing technologies for CBTC system as research and analysis object, strives to grasp the main focus and development direction of test technology in the field of rail transit signal control.
