METHOD OF RETAINING SPACING IN MULTICABIN ELEVATOR WELL AND ELEVATOR SYSTEM Russian patent published in 2012 - IPC B66B1/14 B66B1/24 

FIELD: transport.

SUBSTANCE: invention relates to elevators. Proposed method comprises defining leading cabin brake path and normal path of the next cabin. Then, difference between normal and shortest brake paths is adjusted relative to threshold distance. In adjustment, distance between leading and next cabins is kept equal to, at least, separation distance. In delay of the next cabin start, planned motion time 0≤T≤T_t, location θ_t and next cabin normal braking path π_nst, planned motion time 0≤T≤T₁, location θ₁ and shortest braking path π_ssl are defined. Conditions |θ_l (T+T_run)+K_ssl(T+T_run))-(θ_t(T)+ π_nst(T)|≥d_thresh are verified where 0≤T≤min {T_t, T_l-T_run}, where T_run is actual motion time of leading cabin, d_thresh is threshold distance while 0≤T_run≤T_l. Elevator system comprises well, leading and next cabins and controller to implement proposed method.

EFFECT: higher safety and quality.
