Abstract
The invention discloses a method for realizing the detection of motor contracting brake force. The technical scheme can prevent the out-of-control running caused by shortage of contracting brake force and avoid the occurrence of safety accidents, component damage, etc. At the same time, using the method can be convenient for site workers to diagnose the faults such as contracting brake, etc., and detecting the value of locked-rotor torque of motor in the process of contracting brake can judge whether or not the contracting force is adequate when the motor stops running. If the contracting force is adequate, the faults do not occur. If the contracting force is not adequate, two grade fault codes are classified according to the value of the contracting force of contracting brake: system stop fault codes generated by serious shortage of contracting brake force and indicative fault codes generated by slight shortage of contracting brake force.

Product does not still have the function that band-type brake power detects at present, just when motor operation, monitors the state of band-type brake.Generally do not monitor when stopping, even monitor, also can only be by band-type brake detecting switch (detecting the gap between brake facing and wheel hub), rough know the general state of band-type brake.And whether concrete band-type brake power satisfies the requirement of system inertia, does not have concrete quantification, can not reliably detect the size of band-type brake power.
Summary of the invention:
In order to overcome above-mentioned defective of the prior art, the purpose of this invention is to provide a kind of method that realizes brake sticking force detection of motor.This technical scheme can prevent the uncontrollable operation that causes because of band-type brake power deficiency, avoids causing items such as safety misadventure and portion's product damage.Simultaneously can also make things convenient for the field staff to Fault Diagnosis such as band-type brakes.
The inventive method can utilize programming language to realize the technique effect that can reach with the form of application program.Specifically comprise the steps:
When (1) being in dormant state, judge whether system opens the function of brake sticking force detection, the words execution in step (2) that is in system; Otherwise finish this detecting operational process;
(2) judge whether in the fixed cycle, not carry out the brake sticking force detection formula, artificial M/C is perhaps arranged, the words execution in step (3) that is; Otherwise finish this detecting operational process;
(3) judge whether correlation parameter is provided with, the words band-type brake that is is embraced, and applies the standard torque value of wretched insufficiency to motor; Otherwise produce indicative fault reflection parameter mistake is set;
(4) judge whether elevator slippage takes place, the words that are generate the fault reflection band-type brake power wretched insufficiency that stops and artificially remove fault and can move; Otherwise band-type brake is embraced, and applies the standard torque of slight deficiency to motor
(5) judge whether elevator slippage takes place, the words that are generate gently foot of indicative wrong reflection band-type brake strength, can normally move; Otherwise finish this detecting operational process.
When motor stopped, motor stall square was little when embracing by detecting band-type brake, judges whether the power of band-type brake is enough as above-mentioned technical step speech.As enough, just do not produce fault, as inadequately, then be divided into two grade level diagnostic code according to the size of embracing power: band-type brake power wretched insufficiency just generates and makes system stop fault; Band-type brake power is slightly not enough, just generates indicative fault.
System once detects automatically every a fixing cycle; Also can there be the field staff to grasp instant detecting.
The beneficial effect of the inventive method is:
1) convenient on-the-spot repair and maintenance personnel are to the judgement of motor band-type brake situation;
2) guarantee that system moves and the safety of hardware;
3) in time detect the band-type brake fault, avoid system's safety misadventure that causes out of control to take place;
Whether 4) can judge on-the-spot motor band-type brake and adhere to specification, the prompting field staff in time transfers lock power.
Description of drawings:
Further specify the present invention below in conjunction with the drawings and specific embodiments.
Fig. 1 is the flow chart of steps of the inventive method.
Fig. 2 detects the scheme drawing that the formula moment of torsion applies for band-type brake power.
The specific embodiment:
For technological means, creation characteristic that the present invention is realized, reach purpose and effect and be easy to understand and further set forth the present invention below in conjunction with concrete diagram.
Referring to Fig. 1, the specific implementation process of this technical scheme is:
When (1) being in dormant state in system, judging whether system opens the function of brake sticking force detection, is execution in step (2); Otherwise finish this detecting operational process;
(2) judge whether in the fixed cycle, not carry out the brake sticking force detection formula, artificial M/C is perhaps arranged, the words execution in step (3) that is; Otherwise finish this detecting operational process;
(3) judge whether correlation parameter is provided with, the words band-type brake that is is embraced, and applies the standard torque value of wretched insufficiency to motor; Otherwise produce indicative fault reflection parameter mistake is set;
(4) judge whether elevator slippage takes place, the words that are generate the fault reflection band-type brake power wretched insufficiency that stops, and need the artificial fault of removing to move; Otherwise band-type brake is embraced, and applies the standard torque value of slight deficiency to motor;
(5) judge whether elevator slippage takes place, it is slightly not enough that the words that are generate indicative wrong reflection band-type brake strength, can normally move; Otherwise finish this detecting operational process.
The procedure declaration of brake sticking force detection:
1) band-type brake is embraced, and applies a quite little moment of torsion (band-type brake power greater than this moment of torsion time, system can under normal circumstances move) to motor, with respect to the first area of Fig. 2.As this moment motor can rotate, band-type brake power wretched insufficiency is described, system should not work again.So generate the fault reflection band-type brake power wretched insufficiency that stops, need the artificial fault of removing to move; As this moment motor can not rotate, illustrate that band-type brake power satisfies the operation under the normal circumstances, enters next step.
2) do not generate fault as step 1, then continue to increase torsion,, be equivalent to the second area of Fig. 2 under all states to a higher value (band-type brake power greater than this moment of torsion time, system can move).As this moment motor can rotate, illustrate that band-type brake power is slightly not enough, system can work again, generates indicative fault, reminds the repair and maintenance personnel; As this moment motor can not rotate, illustrate that band-type brake power is normal fully.
By utilizing system's its other resources, in control system, append software as above-mentioned step speech: when motor stops, motor is applied certain torque, detect motor simultaneously and have or not and rotate, produce different faults according to the situation that has or not rotation.
