Abstract: In this paper, the signaling equipment setting of the comprehensive training base of China Railway Kunming Group Co., Ltd. is taken as the background, in order to meet the requirements of on-site signalman skills training, considering the two important factors of outdoor station area and saving funds, the way of "practical + simulation" is adopted, and the design and optimization scheme of the simulated turnout circuit is proposed and verified. The design circuit conforms to the "fail-safe" principle through the interlocking test, and can effectively meet the needs of simulated turnout circuit design in the construction of signal training base.

Key words: simulated turnout circuit, interface circuit, control circuit
