Abstract
The invention discloses a control method of synchronizing lifting heights of multiple lifters. Each lifter is provided with an independent drive motor; multiple lifters are provided with a same datum plane and provided with position sensors respectively on the datum plane; and a control system controls the times of drive motors driving the corresponding lifters to lift to be same through time relays respectively and controls the drive motors to drive the corresponding lifters to descend to the datum plane through the corresponding position sensors. According to the control method, as the position sensors are adopted to control multiple lifters to fall back on the same datum plane, and the time relays are adopted to control the lifting times of multiple lifters to be same, the lifting heights of multiple lifters are basically same, and synchronous operation is not influenced with a deviation within a permissible range; and in addition, along with return operation of the lifters, the deviation can be eliminated without generating an accumulative deviation, and multiple lifters can be ensured to carry out long-term synchronous operation.
Description
Technical field
The present invention relates to the control method of a kind of Multi-Machine Synchronous, particularly relate to the control method that a kind of multiple stage elevator adjustable height synchronizes.
Background technology
The amphibious soft base board plug device of muddy water has 5 buoyancy tanks, and each buoyancy tank has 4 elevator, and whole table apparatus has 20 elevator.The existing height-rise high-fall action of these elevator, has again the descending operation by buoyancy tank packet.
Although First model machine adopts the control mode of relay+catalyst can ensure that, the drive motor energising of each elevator is essentially identical with the time of power-off, but due to difference such as each motor coil windings, the rotating speed of motor has some differences, and the stress size of each elevator also can be different, cause the descending operation through after a while, 20 elevator there will be the difference of short transverse, and deviation can progressively be accumulated and be affected operation the most at last.
Nearest optimizing design scheme is: amendment control system, photoelectric sensor is adopted to read the adjustable height of elevator, control system controls the start-stop time of motor according to the adjustable height signal from photoelectric sensor, but carrying out lifting and find during functional test, due to the butter being stained with on the screw mandrel of elevator, the foreign material such as silt can block photoelectric sensor, simultaneously screw mandrel lifting process rocks the counting also influencing whether photoelectric sensor, cause photoelectric sensor counting confusion, and randomness does not have very by force rule, cause the actual adjustable height of elevator and setting height inconsistent.This kind of control mode is excluded.
Summary of the invention
The present invention solves the technical problem and the control method that provides a kind of multiple stage elevator adjustable height to synchronize that exist in known technology, the method can by the adjustable height error control of multiple stage elevator within the deviation range allowed, it is ensured that multiple stage elevator can work asynchronously for a long time.
The present invention solves that the technical problem existed in known technology is adopted the technical scheme that: the control method that a kind of multiple stage elevator adjustable height synchronizes, every described elevator is provided with an independent driving motor, elevator described in multiple stage is provided with same datum level, elevator described in multiple stage is respectively provided with a position sensor on described datum level, described control system controls described drive motor by the time relay and drives the time that elevator hoists identical, and described control system controls described drive motor by described position sensor and drives elevator to drop to described datum level.
Every corresponding described time relay of described elevator.
The present invention has the advantage that and has the benefit effect that employing position sensor controls multiple stage elevator and falls after rise to same datum level, the hoisting time adopting time relay control multiple stage elevator is identical, and then make the lifting heights of multiple stage elevator essentially identical, deviation within the range of permission, does not affect synchronization job.And along with the return of elevator operates, this deviation will be eliminated, and will not build up sexual deviation, it is ensured that multiple stage elevator can work asynchronously for a long time.
Detailed description of the invention
For the summary of the invention of the present invention, feature and effect can be further appreciated that, hereby enumerate following example and illustrate:
The control method that a kind of multiple stage elevator adjustable height synchronizes, every described elevator is provided with an independent driving motor, elevator described in multiple stage is provided with same datum level, elevator described in multiple stage is respectively provided with a position sensor on described datum level, described control system controls described drive motor by the time relay and drives the time that elevator hoists identical, and described control system controls described drive motor by described position sensor and drives elevator to drop to described datum level.
For the ease of controlling the part elevator synchronization lifting in multiple stage elevator, every corresponding described time relay of described elevator.
When the amphibious soft base board plug device of muddy water applies above-mentioned control method, solve the nonsynchronous problem of elevator preferably.Its operation principle is: 20 elevator are installation site sensor on the unified datum level of lowest order all, and the return of elevator can return on identical datum level so each time.The height that elevator rises is controlled by the time relay, although the rotating speed of each motor is different, suffered load is different, the height risen within the identical time that the time relay controls has deviation, but error is relatively small, completely within the deviation allowed, do not affect the normal operation of board plug device.Along with the return of elevator operates, this deviation will be eliminated, and will not build up sexual deviation.
Although being described above in conjunction with the preferred embodiments of the present invention; but the invention is not limited in above-mentioned detailed description of the invention; above-mentioned detailed description of the invention is merely schematic; it is not restrictive; those of ordinary skill in the art is under the enlightenment of the present invention; when without departing from present inventive concept and scope of the claimed protection, it is also possible to making a lot of form, these belong within protection scope of the present invention.
