With the rapid development of high-speed rail technology,the task of upgrading the existing railway lines in China has become increasingly difficult,especially in the field of signal control system upgrades.Focusing on the compatibility problem be-tween the eight-wire track control circuit and the five-wire turnout machine,this paper analyzes the principles of the eight-wire and five-wire track control circuits in depth,clarifies the differences between the starting circuits and indicates circuits of the two systems,and designs a circuit switching switch to improve the shortcoming that the previous similar design required adjusting the internal wiring of the turnout machine.This design achieves effective control of the eight-wire track control circuit over the five-wire turnout machine,improving the efficiency and flexibility of the upgrade project,and providing a reliable technical solution for the smooth transition of the railway signal system.
