Abstract: The logic check function of section track circuit is realized mostly by adding the function of TCC in the high-speed railways and inter-city railways, and by adding the relay circuit and QJK in conventional speed railways . In the case of non-synchronous overhaul of existing lines, adding logic check function is restricted by construction conditions, time of maintennance-skylinght, personnel organization, etc., which is difficult and risky. According to the actual construction situation of existing railways, this paper summarizes the test methods in the above two ways respectively, discusses the test items, test methods and test contents in detail, optimizes the interlocking test scheme, reduces the workload and ensures that the interlocking relationship is absolutely correct.

Key words: logic check, interlocking test, QJK
