Abstract: In Chengdu Metro Line 1 & line 2, the interlocking system of the main lines is Microlok II (MLK for short), and its difference with the traditional interlocking system is adopting Boolean algebra and using Boolean variable state numbers instead of partial relays in the traditional interlocking system. By means of the auxiliary development tool MLK-CC 3.0, maintenance personnel can online monitor MLK running status and logic operation, download historical events and analyze relevant faults. This paper focuses on analyzing routs setting and release of main line interlocking logics to ifnd out the causes of the faults through analyzing the state change of each Boolean variable, for ensuring efifcient operation of signal equipment.
