Description
Technical field
The present invention relates to a kind of elevator device with and the control method of this system, particularly relate to a kind of system that realizes direct stopping of elevator with and control method.
Background technology
Elevator mostly adopts the creep strategy of certain distance of dead slow speed to realize flat bed when flat bed in the market, and this method has bigger limitation in actual applications.At first, because the existence of dead slow speed crawl time causes the elevator operating efficiency not high; Secondly, be the control creeper speed time, the distance of creeping just needs accuracy control; this just needs product just can reach through accurate test before dispatching from the factory; in addition, when on-the-spot elevator has slippage, often cause elevator anxious stopping or the phenomenon generation of length of dead slow speed crawl time when flat bed, to occur easily.For this reason, be badly in need of the system of a kind of direct stopping of elevator of exploitation and the control method of this system and solve the problems referred to above.
Summary of the invention
At the problems referred to above, main purpose of the present invention be to provide a kind of system that realizes direct stopping of elevator with and control method, the present invention solves above-mentioned technical matters by following technical proposals: the present invention includes: master control board, frequency converter, electrical motor, coder, the flat bed inductive switch, ductor, car, hoistway, described flat bed inductive switch is installed on the sidewall of described car, described ductor is fixed on each floor position place on the hoistway wall, drag car and move up and down by drag running wheel and the steel rope that is installed between electrical motor and the car, it is characterized in that: described master control board is by the flat bed inductive switch, ductor, signal on the coder obtains accurate position of each stop and the absolute location of car in hoistway, the start and stop of described master control board control frequency converter, moving up and down of the direct motor drive lift car of Frequency Converter Control, master control board obtains the target Distance Remaining of elevator and the speed of elevator by code device signal, determine the velocity curve and the deceleration point of elevator, when elevator arrives the target stop soon, know the actual distance that arrives the target stop by flat bed inductive switch that is contained in car upper and the ductor that is contained in each floor position place on the hoistway wall, and by this to elevator speed, acceleration/accel is revised, and makes elevator steady, rest in the target location accurately.
Wherein, described control method comprises the steps:
1). master control board before elevator starts by in advance from the stop position that chooses, and destination position, selected one suitable running velocity is determined the deceleration of elevator point automatically, and start, control inverter control motor driving car moves up and down;
2). elevator is in operational process, and master control board is by the real time position and the speed of coder acquisition car, and whether needs slow down to determine elevator according to the deceleration point that pre-determines;
3). car runs slowly and enters the flat bed scope, and ductor begins to cut the flat bed inductive switch and makes the action of flat bed inductive switch, and master control board knows the target range of elevator reality by flat bed inductive switch actuating signal;
4). according to passing through the detected cage operation speed of coder, acceleration/accel, and target range, master control board recomputates and determines new parameters of elevator run, and the control inverter control motor drives cage operation, and the elevator zero-speed is rested on the level position.
Positive progressive effect of the present invention is: the present invention is owing to realize directly stopping, elevator operating efficiency, flat bed stationarity have been improved, simultaneously elevator is exempted to adjust and is minimumly moved rank height, the shortest deceleration distance and the permissible velocity deviation range during through each limit switch, can save human and material resources.
