The reminding passengers such as display screen pay attention to.And the level position is compensated, elevator is enable normally to put down when the layer opens the door in next time
Layer.B. leveling is abnormal, and when in safe range, then buzzer is not rung, reminding passengers are re-started flat note that simultaneously close the door at a slow speed
Layer back pullout (BPO).When sill is higher or relatively low, master control system sends warning message and reminds maintenance staff to elevator to monitoring center
Component is checked.
It is A, car sill and landing sill from car sill horizontal distance if the height that camera is installed in carriage is B
Between horizontal distance be L.Difference in height between car sill and car door sill is h, then can obtain in the picture that camera captures
(Fig. 6 d), the angle between layer car door sill are θ1.L is usually determination in elevator, according to formulaAnd public affairs
FormulaIt is found that leveling difference in height h determines θ1Size.If total visual angle size of camera is
θ passes through θ in shooting image1Part occupies θ in the size or shooting image of total view angle theta1Part and θ2Partial ratio, can be with
Judge the whether normal leveling of elevator.θ is assumed in the case of normal leveling1Value be M, then when gate be higher than landing sill when, θ1<
M.When layer door is higher than car door sill, θ1>M.Utilize θ in shooting image1Size can learn that sill is higher or relatively low.
