Elevator is the equipment of riding instead of walk of indispensable vertical lift in the daily life.The operation of elevator is to run to another layer by one deck in vertical direction, and therefore, elevator control gear need obtain the information of lift car current location, and promptly which stop lift car is in.If the staggered floor fault promptly takes place for the position of control setup wrong identification car or current stop, then may cause following problem: (1) elevator can not run to correct stop; When (2) elevator runs to the end station, go out end position, cause the end accident of rushing to summit or squat owing to running velocity is too high; (3) the accurate flat bed of elevator.This shows that staggered floor is a kind of serious fault.
In order to prevent the generation of staggered floor fault, generally can take following method in the prior art:
(1) at every stop an independently detector switch is set.For example, the car stop position of each stop is provided with detector switch (as dry reed switch, near switch) in elevator hoistways, at the car of elevator corresponding detected device (as permanent magnet, metal sheet etc.) is installed, and detector switch is connected to elevator main controller.When lift car during near certain stop, the action of the detector switch of corresponding floor, elevator main controller just can be determined the accurate stop of elevator.But this method N layer just needs N leveling switch, and wiring is many, and the cost height is difficult in maintenance, only is adapted at the low layer elevator and uses.
(2) the elevator absolute position transducer is installed, as steel encoded tape, laser rangefinder, installation absolute value encoder or the like on velocity limiter.But some cost height of these methods, some reliability is not high, so field of application is wideless.
(3) incremental encoder is installed is calculated the elevator displacement dragging on the motor that draws machine, rely on the speed reducing switch that forces at end station to proofread and correct stop.Low, the easy realization of this method cost is the technology that present most of elevator adopts.But because there is the risk of staggered floor in skidding and the interference and the correcting action of leveling switch of steel rope during the elevator operation, the situation that especially reruns after power failure if when having a power failure mobile car took place, then is easy to cause staggered floor.
