The reminding passengers such as display screen pay attention to.And when being opened the door in the layer next time, the level position is compensated, elevator is normally put down
Layer.B. flat bed is abnormal, when not in safe range, then buzzer rings, and reminding passengers pay attention to, and close the door at a slow speed, re-start flat
Layer back pullout (BPO).When sill is higher or relatively low, master control system sends warning message and reminds maintenance staff to elevator to Surveillance center
Part is checked.
It is A, car sill and landing sill from car sill horizontal range if the height that camera is installed in car is B
Between horizontal range be L.Difference in height between car sill and car door sill is h, then in the picture that can obtain camera capture
(Fig. 6 d), the angle between layer car door sill is θ1.What L was typically to determine in elevator, according to formulaAnd public affairs
FormulaUnderstand, flat bed difference in height h determines θ1Size.If total visual angle size of camera is
θ, pass through θ in shooting image1Partly take θ in the size or shooting image of total view angle theta1Part and θ2Partial ratio, can be with
Judge the whether normal flat bed of elevator.Assume θ in the case of normal flat bed1Value be M, then when gate is higher than landing sill, its θ1<
M.When layer door is higher than car door sill, its θ1>M.Utilize θ in shooting image1Size can learn that sill is higher or relatively low.
