= | (ΣΔX + XA) − (XB + XA) | (1)
△ X is the amount of car movement per pulse of the governor encoder, XA is the floor reference position, XB is the distance between the floor reference position and the landing reference position (predetermined value), and Σ △ X is the car passing the floor reference position The amount of movement of the car from the point in time when the car travel direction is determined by the car travel
現在のかご位置とかご停止階(または最寄り階)の着床基準位置との判定距離X(基準位置からのかごの移動距離)を算出する(F03)。 When the door is open, the speed of the car is detected (F02).
A determination distance X (a moving distance of the car from the reference position) between the current car position and the landing reference position of the car stop floor (or the nearest floor) is calculated (F03).
図6(A)は、かごに多人数が乗車した場合の主ロープの伸びによるかご動作(位置および速度の動作)を表している。動作軌跡C01は、動作点の軌跡を示し、矢印の向きが時間的な進行である。始点において、かごは着床基準位置に停止(速度ゼロ)している。かごに多人数が乗車したことにより、ロープが伸びてかごが速度を上げながら下降して、ある位置で停止し、バネの振動のように、次は上昇,下降という振動を繰り返して、終点の位置で静止する。 An operation region (curve A06) of normal door-opening traveling due to rope elongation will be described.
FIG. 6A shows a car operation (position and speed operation) due to the extension of the main rope when a large number of people get on the car. The motion trajectory C01 indicates the trajectory of the motion point, and the direction of the arrow is time progress. At the start point, the car stops at the landing reference position (zero speed). When a large number of people get on the car, the rope stretches and the car descends while increasing the speed, stops at a certain position, and repeats the vibration of rising and lowering next to the end of the end point like the vibration of the spring. Still at position.
V=√{2・β・(X0-X)} (2)

図12(A)はかごの階位置が最上階の場合であり、かごを吊り下げている主ロープの長さが短いため、ロープ伸縮による振動幅は小さく、ロープ伸びによる戸開走行の正常領域(一点鎖線A06で囲まれた領域)も小さくなる。従って、異常判定曲線(曲線A03)の半径(中心は着床基準位置)も小さくする。つまり、同じかご位置に対する速度異常の判定しきい値が小さくなる。 FIG. 12 shows an example of determination characteristics set for each floor.
FIG. 12 (A) shows the case where the floor position of the car is the top floor, and since the length of the main rope that suspends the car is short, the vibration width due to the rope expansion and contraction is small, and the normal region of the door opening traveling due to the rope extension (A region surrounded by an alternate long and short dash line A06) is also reduced. Therefore, the radius (center is the reference landing position) of the abnormality determination curve (curve A03) is also reduced. In other words, the speed abnormality determination threshold for the same car position is reduced.
