Embodiment Construction
[0030] like figure 1 As shown, a method for re-determining after the power running direction of a rail transit vehicle is changed is characterized in that it includes a speed threshold register 1, a fault clearing signal register 2, a direction normal setting memory 3, an operating speed register 4, and a forward bit signal Register 5, zero speed register 6, delay confirmation flip-flop 7, NOT gate 8, first comparator 9, AND gate 10, selection switch 11, second comparator 12 and direction lock logic controller 13; Wherein:
[0031] The speed threshold register 1 receives and stores the set speed threshold data and inputs the data to the first input terminals of the first comparator 9 and the second comparator 12; the zero speed register 6 receives and stores zero speed signal data;
[0032] The fault clearing signal register 2 receives and stores the action signal from the "fault clearing" button of the driver's console, and the signal is input to the delayed confirmation fli...
