By analyzing the advantages and disadvantages of existing tram signal system control schemes,a tram signal system control scheme with centralized interlocking and distributed control is proposed,taking the tram signal system project in the Ice and Snow Town of Zhangjiakou Chongli Olympic Zone as the research object.This plan not only simplifies the overall system architecture,reduces the complexity of system composition,but also effectively ensures the safety of train operation in various switch areas of the tram,and controls human safety risks.
