Description
Technical field
The present invention relates to mechanical field, refer to especially a kind of lift control method.
Background technology
Along with the aggravation of urbanization process, increasing Tall Office Building, residential building stand in great numbers and rise, in process of construction, need jacking system that workman is transported to construction floor, after building up, need elevator that resident family is delivered to every family, elevator is also a kind of jacking system, therefore, jacking system is transportation means indispensable in city, is directly connected to people's live and work quality.
Jacking system is by traction system output and transferring power, and existing traction system is mainly by towing machine, traction steel-cable, track adjusting wheel, diversion sheave composition.Therefore, existing traction system is by lifting, acceleration and the deceleration of the tractive force control envelope of steel rope, start and stop process in have obvious weightless sense, even cause the dizzy of passenger, for hypertension or there is the passenger of other diseases to have significantly uncomfortable.
Although a lot of R&D teams have carried out a lot of innovations and improvement to towing machine and control circuit thereof, startup and stop process are also more evenly mild, but cannot fundamentally overcome the intrinsic shortcoming of traction system, therefore, how a kind of steadily comfortable lift control method is provided, and is current problem demanding prompt solution.
Summary of the invention
The present invention proposes a kind of lift control method, solved that traction system in prior art starts and stop process in have the problem of weightless sense.
Technical scheme of the present invention is achieved in that
A kind of lift control method, comprises the following steps:
Step (a), at three closed side wall arranged outside of envelope the first electromagnetism winding;
Step (b) arranges the second electromagnetism winding with described the first electromagnetism winding relative position place on every layer of wall of elevator;
Step (c), setting position sensor on every layer of wall of elevator;
Step (d), by controller, is connected to described position transduser, receives the position signal of envelope, outputs a control signal to towing machine, the first electromagnetism winding and the second electromagnetism winding.
Alternatively, in described step (d), be connected to described position transduser by dsp processor, receive the position signal of envelope, output a control signal to towing machine, the first electromagnetism winding and the second electromagnetism winding.
Alternatively, in described step (d), be connected to described position transduser by TMS320F2812 dsp processor, receive the position signal of envelope, output a control signal to towing machine, the first electromagnetism winding and the second electromagnetism winding.
The invention has the beneficial effects as follows:
Produce resistance by the magnetic resistance between electromagnetism winding, the envelope of jacking system is produced to braking force, startup and the stop process of auxiliary towing machine, make the startup of envelope and stop more steady.
Brief description of the drawings
In order to be illustrated more clearly in the embodiment of the present invention or technical scheme of the prior art, to the accompanying drawing of required use in embodiment or description of the Prior Art be briefly described below, apparently, accompanying drawing in the following describes is only some embodiments of the present invention, for those of ordinary skill in the art, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the diagram of circuit of a kind of lift control method of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, the technical scheme in the embodiment of the present invention is clearly and completely described, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiment.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
Existing traction system is mainly by towing machine, traction steel-cable, track adjusting wheel, diversion sheave composition.Therefore, existing traction system, by lifting, acceleration and the deceleration of the tractive force control envelope of steel rope, has obvious weightless sense in startup and stop process.
For addressing the above problem, the invention provides and a kind ofly there is electromagnetism winding the lift control method of electromagnetic resistance is provided.
As shown in Figure 1, a kind of lift control method of the present invention, comprises the following steps:
Step (a), at three closed side wall arranged outside of envelope the first electromagnetism winding;
Step (b) arranges the second electromagnetism winding with described the first electromagnetism winding relative position place on every layer of wall of elevator;
Step (c), setting position sensor on every layer of wall of elevator;
Step (d), by controller, is connected to described position transduser, receives the position signal of envelope, outputs a control signal to towing machine, the first electromagnetism winding and the second electromagnetism winding.
By regulating the size and Orientation of current flowing in the first electromagnetism winding and the second electromagnetism winding, change the magnetic resistance between the first electromagnetism winding and the second electromagnetism winding, and then change the electromagnetic resistance between the first electromagnetism winding and the second electromagnetism winding, when making to realize envelope traction coarse adjustment by towing machine, realize the accurate adjustment of envelope braking force by the first electromagnetism winding and the second electromagnetism winding, make startup and the stop of envelope more steady, passenger's experience is more comfortable.
Preferably, in described step (d), be connected to described position transduser by dsp processor, receive the position signal of envelope, output a control signal to towing machine, the first electromagnetism winding and the second electromagnetism winding.
Preferably, in described step (d), be connected to described position transduser by TMS320F2812 dsp processor, receive the position signal of envelope, output a control signal to towing machine, the first electromagnetism winding and the second electromagnetism winding.
TMS320F2812 DSP, is 32 fixed DSPs, and the AD data acquisition that it has EVA, EVB task manager and supporting 12 16 passages, has abundant Peripheral Interface, as CAN, SCI etc.The ADC module of TMS320F2812 is 12 bit resolutions, has the A and D converter of pipeline organization, the built-in dual-sampling hold circuit of TMS320F2812, and while keeping data acquisition, window has independently pre-calibration to control.And permission system is to same Channel-shifted repeatedly, allow user to carry out over-sampling algorithm, this more traditional single transformation result has increased more solution, is conducive to improve the precision of sampling.There are multiple trigger sources can start ADC conversion.Fast speed transfer time, ADC clock can be configured to 25MHz, and the highest sampling bandwidth is 12.5MSPS.While building data acquisition system with TMS320F2812, needn't external ADC, avoid complicated hardware design.
Lift control method of the present invention produces resistance by the magnetic resistance between electromagnetism winding, and the envelope of jacking system is produced to braking force, and startup and the stop process of auxiliary towing machine make the startup of envelope and stop more steady.
The foregoing is only preferred embodiment of the present invention, in order to limit the present invention, within the spirit and principles in the present invention not all, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
