Suppose the operation indication based on elevator operation portion 23, car 16 moves to 1 layer → 2 layers → 4 layers → 3 layers.At moment t
1, car 16 when setting out for 1 layer, the speed v of car 16
1Rise to specified speed v
H
And, car 16, the moment before the moment t2 of 2 layers of arrival reduces speed now.Owing to be about to due in t
2Before, car 16 just enters the adimission area 28 of opening the door, so the adimission area detection signal e that opens the door rises.
Arrive 2 layers moment t2 at car 16, the enabling signal h of elevator operation portion 23 rises, and each 24,20 is opened.Its result, the detection signal d that opens the door of the door 24 of car 16 rises.At this moment t2, because the speed v of car 16
1Be lower than allowed value v
SSo the abnormality juding portion 27 of travelling can not be judged to be unusual f has taken place to travel
1
Then, when at moment t
3, based on releasing (open the door instruction h decline) and the operation indication of the instruction h that opens the door, car 16 begins when mobile, the speed v of car 16
1Begin to rise, and the detection signal d that opens the door descends.

5The moment before begins from specified speed v
HRise and slow down, but under the situation that begins to postpone because the mistake aspect the software of elevator operation portion 23 causes slowing down, at moment t
5, speed v
1Can surpass allowed value v
SAt this moment t
5, the abnormality juding portion 27 of travelling is judged to be unusual f has taken place to travel
1
Its result, the abnormality juding portion 27 pairs of brakings instruction unit of travelling 31 indication output speed-slackening signal b
2, and electric power is stopped instruction unit 32 indication output powers stop to indicate g.Therefore, the rotary work of the S. A. 11 of electrical motor 10 is braked, and supply with for the electric power of electrical motor 10 to be cut off, thereby electrical motor 10 stops.

6Arrival predetermined instant t from 3 layers of 4 courses
8Moving process in moment t
7, from the instruction h that opens the door of out gate 24 mistakenly of elevator operation portion 23, then since door 24,20 in fact open, so the detection signal d that opens the door rises.
But, because car 16 does not arrive the adimission area 28 of opening the door, so the adimission area detection signal e that opens the door does not also rise.Its result and since comprised between the period of output of detection signal d that opens the door not output open the door adimission area detection signal e during, so at this t constantly
7, the abnormality juding portion 27 of travelling is judged to be unusual f has taken place to travel
2
Therefore, the abnormality juding portion 27 of travelling, 31 indications are exported speed-slackening signal b to brake equipment 13 to the braking instruction unit
2, and electric power is stopped instruction unit 32 indication output powers stop to indicate g.Therefore, the rotary work of the S. A. 11 of electrical motor 10 is braked, and supply with for the electric power of electrical motor 10 to be cut off, thereby electrical motor 10 stops.
In the safety device of the elevator of first embodiment that constitutes like this, even owing to for example mistake aspect the generation software in elevator operation portion 23 elevator control gears such as grade, thereby under door 24,20 states that are opened, also can utilize with respect to this elevator control gear each part mentioned above independently, the work of car 16 is stopped at once, so can guarantee safety for the user.
Promptly, in the safety device of the elevator that constitutes like this, with the electrical motor that is supplied to electric power from power converter portion the using escalator position of each floor of car in the lift path of building is moved, and make the door of car open the groundwork of such elevator operation, carry out by the elevator operation portion that constitutes with computing machine etc.
And, because brake equipment, the test section that opens the door, the adimission area test section that opens the door, speed leading-out portion, travel abnormality juding portion by with above-mentioned elevator operation portion independently the hierarchy of control make up, even the therefore elevator operation portion move of output car during door is opened mistakenly, thereby make car begin to move, also since under moving velocity has surpassed the situation of allowed value, during door is opened car be not present under the situation in the adimission area of opening the door, brake equipment is worked automatically, so guaranteed for user's safety.
