Description
Technical field
The present invention relates to a kind of method of measurement of numerical value, particularly a kind of method of measurement of balance coefficient of elevator.
Background technology
According to elevator industry standard and inspection criterion, the equilibrium factor that elevator need meet certain requirements.The test method of common equilibrium factor is very loaded down with trivial details, lift car is needed to load different load-carryings, allow the upper and lower operation of elevator, detect at lift car with to motor current value when focusing on same level position respectively, ascending current curve and centrifugal current curve are carried out described point mapping electric current-load curve, determine equilibrium factor by intersection point.The method needs artificial setting and mapping related data, and needs to load variant load-carrying, and work capacity is very large.Apparatus for controlling elevator nearly all at present all uses variable frequency control mode, and this makes the measurement of current of electric must be realized by special high-frequency currents pincer table, and common power current pincerlike meter exists certain error.
Summary of the invention
In order to solve the deficiencies in the prior art, the object of this invention is to provide a kind of method of measurement using simply, measure accurate balance coefficient of elevator.
To achieve these goals, the method for measurement of balance coefficient of elevator provided by the invention, is characterized in that:

Detailed description of the invention
As shown in Figure 1, the method for measurement of balance coefficient of elevator provided by the invention, comprises the steps:
S1, in advance setup algorithm formula in elevator main control board;
S2, empty elevator moves to one end automatically;
S3, makes elevator run to the other end;
S4, when car and counterweight move to same level position, elevator main control board record is power of motor, elevator speed parameter storing this moment;
S5, after elevator moves to the other end, then makes elevator run to one end;
S6, when car and counterweight move to same level position, elevator main control board record is power of motor, elevator speed parameter storing this moment;
S7, calculates the parameter stored by master control board, draw and show current equilibrium factor.
Preferably, as shown in Figures 2 and 3, when measuring, elevator first can be made automatically to move to most top layer, then elevator is run to the bottom, when car and counterweight move to same level position, elevator main control board record is power of motor, elevator speed parameter storing this moment, after after this elevator moves to the bottom, then elevator is run to most top layer, when car and counterweight move to same level position, elevator main control board record is power of motor, elevator speed parameter storing this moment; Also can elevator be first made automatically to move to the bottom, elevator is made to run to most top layer again, when car and counterweight move to same level position, elevator main control board record is power of motor, elevator speed parameter storing this moment, after this after elevator moves to most top layer, make elevator run to the bottom again, when car and counterweight move to same level position, elevator main control board record is power of motor, elevator speed parameter storing this moment.
In measurement process, elevator current position information is obtained by the coder in master control board; Elevator speed parameter is obtained by the coder in master control board; Power of motor parameter is obtained by master control board and data of frequency converter communications exchange; Described location information, elevator speed parameter and power of motor parameter are stored in master control board; The numerical value of current equilibrium factor is shown by the telltale of master control board.
Master control board records relevant data in running, and after test terminates, master control board is loaded into the data parameters recorded in test process automatically, carrys out calculated equilibrium coefficient by pre-set formula, and formula is
K=(NsVx+NxVs)/2QgVxVs, wherein:
K is the equilibrium factor of tested elevator
Ns is that unloaded car is up, when running to counterweight same level position, and motor running power, unit is W;
Vs is that unloaded car is up, when running to counterweight same level position, and the speed of car, unit is m/s;
Nx is that unloaded car is descending, when running to counterweight same level position, and motor running power, unit is W;
Vx is that unloaded car is descending, when running to counterweight same level position, and the speed of car, unit is m/s;
Q is the payload ratings of test elevator, and unit is kg, can obtain from the elevator basic specification of master control board setting;
G is acceleration due to gravity, gets 9.81m/s.
The invention has the advantages that, by integrated for all equilibrium factor measuring abilities with apparatus for controlling elevator itself, the location not needing extra installation any, detecting device, do not need any extra people for measurements and calculations, and the full automaticity easily realizing balance coefficient of elevator generates.
More than describe preferred specific embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art just design concept according to the present invention can make many modifications and variations without the need to creative work.Therefore; all technical personnels in the art according to design concept of the present invention on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should within the scope of the present invention and/or by the determined protection domain of claims.
