Description
Technical field
The present invention relates to mechanical field, refer to especially a kind of magnetic resistance hoistway.
Background technology
The size of elevator hoistways is determined according to elevator selection, lift-mounting track and counterweight track on the borehole wall, reserved door opening lift-mounting door.Well headroom has elevator(lift) machine room.
Elevator is by traction system output and transferring power, and existing traction system is mainly by towing machine, traction steel-cable, track adjusting wheel, and diversion sheave forms.Therefore, existing traction system is controlled lifting, acceleration and the deceleration of envelope by the tractive force 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 elevator is provided, and is current problem demanding prompt solution.
Summary of the invention
The present invention proposes a kind of magnetic resistance hoistway, 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 magnetic resistance hoistway, comprising:
Be arranged on the guide groove on elevator hoistways sidewall, guide groove embeds sidewall 10-30 centimetre;
Be arranged on the electromagnetism winding in guide groove, the thickness of electromagnetism winding is 3-6 centimetre;
Described guide groove be fixed on that guide rail on envelope sidewall blocks mutually and, on guide rail, be also provided with electromagnetism winding;
Position transduser, is arranged on the middle position of every layer of sidewall, the position signal of output envelope;
Controller, is connected to described position transduser, receives the position signal of envelope, and output control signal arrives described electromagnetism winding through D/A converter and current relay.
Alternatively, described controller is dsp processor.
Alternatively, described controller is TMS320F2812 dsp processor.
The invention has the beneficial effects as follows:
By the magnetic resistance between electromagnetism winding, produce resistance, the envelope of elevator is produced to braking force, startup and the stop process of auxiliary towing machine, make the startup of envelope and stop more steady.
Accompanying drawing explanation
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 skills, do not paying under the prerequisite of creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the plan structure schematic diagram of a kind of magnetic resistance hoistway of the present invention;
Fig. 2 is the circuit control block diagram of a kind of magnetic resistance hoistway of the present invention.
The specific embodiment
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, rather than whole embodiment.Embodiment based in the present invention, those of ordinary skills, not making the every other embodiment obtaining under creative work prerequisite, belong to the scope of protection of the invention.
For addressing the above problem, the invention provides a kind of magnetic resistance hoistway that electromagnetism winding provides electromagnetic resistance that has.
As depicted in figs. 1 and 2, a kind of magnetic resistance hoistway of the present invention, comprising: be arranged on the guide groove 120 on elevator hoistways sidewall, guide groove embeds sidewall 10-30 centimetre; Be arranged on the electromagnetism winding 50 in guide groove, the thickness of electromagnetism winding 50 is 3-6 centimetre; Described guide groove 120 be fixed on that guide rail 110 on envelope sidewall blocks mutually and, on guide rail, be also provided with electromagnetism winding; Position transduser 10, is arranged on the middle position of every layer of sidewall, the position signal of output envelope; Controller 20, is connected to described position transduser 10, receives the position signal of envelope, and output control signal arrives described electromagnetism winding 50 through D/A converter 30 and current relay 40.
By regulating the size and Orientation of current flowing in electromagnetism winding, change the magnetic resistance between electromagnetism winding, and then change the electromagnetic resistance between electromagnetism winding, by electromagnetism winding, realize the fine adjustment of envelope braking force, make startup and the stop of envelope more steady, passenger's experience is more comfortable.
Preferably, described controller is dsp processor.By dsp processor, be connected to described position transduser, receive the position signal of envelope, output a control signal to electromagnetism winding.
Preferably, described controller is TMS320F2812 dsp processor.By TMS320F2812 dsp processor, be connected to described position transduser, receive the position signal of envelope, output a control signal to 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 a plurality of 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, avoided complicated hardware design.
Magnetic resistance hoistway 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 modification of doing, be equal to replacement, improvement etc., within all should being included in protection scope of the present invention.
