Abstract：Research purposes: The reliability and security of the electric control system for the turnoutof urban mass transitare vital to the entire turnouts. The traditional safety relay controlmode adopted at present can notmeet the requirements of the turnoutprecision and collection of the on -site data and information required by the running control center. Through analysis and discussion on this problem, this paperpresents the solutions to it.
Research conclusions:Compared with the application of the traditional turn outdriving system, this paper analyzes the defects of the controlmode for traditional safety relay, describes the working principle and controlmode of software redundancy control and hardware redundancy control systems, and puts forward that the hardware redundancy control system willbe the developmentdirection for the control system in the future.
