Boxes and baskets position detecting device 16 is made of the analyzer of the position S of well-known detection boxes and baskets 11, and it is arranged on a plurality of positions in the elevating road 10.
Equally, boxes and baskets speed detector 17 is made of the analyzer of the speed V of well-known detection boxes and baskets 11, and it is arranged on a plurality of positions in the elevating road 10.
Elevator car safety 18 reads from the expression boxes and baskets position S of boxes and baskets position detecting device 16 and boxes and baskets speed detector 17 and the detection signal of boxes and baskets speed V, when detecting the unusual hypervelocity that can not normally slow down, it makes drg or 14 actions of urgent hill holder in the winch 13.
Fig. 2 and Fig. 3 are the instruction diagrams that expression is applied to first and second overspeed detection pattern of first example of the present invention, and transverse axis is the position (m) of the boxes and baskets 11 in the elevating road 10, and the longitudinal axis is the speed (m/min) of boxes and baskets 11.
The overspeed detection mode initialization becomes to have the permissible range of regulation, even so that the error at measurment of imaginary external interference and boxes and baskets position detecting device 16 when considering the normal operation of boxes and baskets 11, brake equipment (drg or urgent hill holder 14) does not carry out unnecessary action yet.
In addition, the action of considering the brake equipment of the error at measurment of boxes and baskets position detecting device 16 or regular event postpones, the overspeed detection mode initialization is become to have the permissible range of regulation, so that at least one regular event in a plurality of brake equipments, and the brake equipment brake equipment in addition of regular event is failure to actuate in the deceleration of boxes and baskets 12.
Among Fig. 2,111 expression boxes and baskets 11 towards the landing position of terminating layer while slow down near the time normal deceleration mode, 112 expressions are used to make the first overspeed detection pattern of drg action, and 113 expressions are used to make the 3rd overspeed detection pattern of urgent hill holder 14 actions.
In addition, among Fig. 3,121 expressions are used to generate by the slow down overspeed detection pattern of deceleration instruction of usefulness of winch 13, and it represents when the stop position towards terminating layer can not slow down normally, by the slow down deceleration mode of usefulness of the moment of torsion (deceleration force) of winch 13.

Therefore, can obtain the good elevator safety system of operating efficiency, and not make brake equipment carry out unnecessary action.
Second example
In above-mentioned first example, do not consider error that the situation of shaking because of the mischief of the passenger in the boxes and baskets 11 or each detecting device are contained etc., but also can consider boxes and baskets 11 specifically shake or detect error, judge overspeed condition.
Fig. 4 is the block diagram of expression second example of the present invention and elevator device, and the part identical with aforementioned (with reference to Fig. 1) given same label, perhaps behind label additional " A " and omit its detailed description.
Among Fig. 4, the passengers (especially children) in the boxes and baskets 11 might do the mischief as jumping, shake etc.
The situation that elevator car safety 18A has considered to exist the passenger in the boxes and baskets to shake, and considered that boxes and baskets position detecting device 16A and boxes and baskets speed detector 17A contain error at measurment, judge overspeed condition.
Fig. 5 and Fig. 6 are and earlier figures 3 and the identical instruction diagram of Fig. 4 111 and 112 expressions normal deceleration mode and deceleration mode as hereinbefore.
Among Fig. 5,212 expressions are used to make the first overspeed detection pattern of the drg action in the winch 13, and 213 expressions are used to make the 3rd overspeed detection pattern of urgent hill holder 14 actions.
