Specific embodiment
Below by specific embodiment combination attached drawing, invention is further described in detail.
Elevator start-up course generally successively includes: elevator operation in place and closes the door, door lock closure, elevator internal contracting brake opening, zero
Speed operation, acceleration and deceleration operation.During realizing elevator controlling using sine and cosine encoder, elevator control system needs a timing
Between can just set up enough torque to reach equalising torque, wherein encoder is mounted on machine shaft, for measuring motor
Revolving speed and the angle turned over.The time is commonly defined as starting zero-speed time T0, and within the T0 time, it is defeated that control system controls motor
Torque reaches equalising torque out, if however if time parameter T0 is too small, control system may export enough not yet
Torque, then elevator i.e. bring into operation, such elevator will occur car slipping make passenger's ride comfort be deteriorated, if the time
It is arranged too long, then elevator needs to wait the long period that could run, and will reduce the operational efficiency of elevator, increases the waiting of passenger
Time.For this purpose, the present invention begins to compensate motor torque when elevator starts, and whether real-time detection elevator reaches
Equalising torque, if being immediately finished the compensation to motor torque after reaching balance and being transported using feed speed control scheme control elevator
Row, both can ensure that when starting that elevator can set up enough torque in this way prevents car slipping, while can be improved the operation of system
Efficiency.
Embodiment 1:
Referring to FIG. 1, the present embodiment provides a kind of elevators to start control method, comprising the following steps:
Step 101: motor torque being compensated after elevator internal contracting brake opening；
Step 102: whether the motor torque for detecting elevator reaches equalising torque, if then terminating the benefit to motor torque
It repays.
Elevator is under different load conditions, and the settling time of equalising torque is different, and under normal circumstances, elevator load is bigger
Then the settling time of equalising torque is longer, but according to the difference of the type of elevator and control method, be also instead sometimes
The settling time of equalising torque is longer when elevator no-load, so if controlling the starting of elevator using a kind of control strategy
Journey is occurred car slipping phenomenon because elevator torque does not set up balance sometimes, can sometimes be had built up due to motor torque flat
It weighs but is still to just bring into operation until control strategy has executed.Wherein, it after elevator internal contracting brake opening, is mended using preset torque
It repays mode to compensate motor torque, frequency converter exports torque appropriate and loading moment keeps balancing, and ties up after reaching balance
It is constant to hold the torque current, guarantees that elevator is in stable state.The elevator starting control method provided through this embodiment, can be with
According to the different loads state of elevator, motor torque is compensated using preset torque compensation mode in elevator starting,
So that motor torque is reached balance as early as possible prevents car slipping, while during torque compensation, the control system of real-time detection elevator is
It is no to reach equalising torque, torque compensation mode is immediately exited from if reaching, and is transported using normal acceleration and deceleration scheme control elevator
Row, improves operational efficiency.By the control method of this embodiment, according to the different equalising torques of load when elevator each run
The time of foundation is different, immediately begins to run when the weight in bridge compartment and counterweight is closer to, has saved the waiting time, ensure that
Elevator stable operation not car slipping while reduce the waiting time, improve elevator operating efficiency.
When general elevator reaches load balance, torque current maintains fluctuation in a lesser range, encoder
Pulse also remains unchanged substantially.Whether the motor torque of real-time judge elevator control system reaches equalising torque in the present embodiment
Method are as follows: the pulse current information and encoder pulse change information of detection motor output in real time, if in the first preset duration
Internal torque curent change is in the first preset range and encoder pulse remains unchanged, then it represents that the control system of elevator reaches
Equalising torque.Specifically, timing can be carried out by timer, start one when elevator starts and enters torque compensation mode
A timer Timer1, the torque current of real-time detection motor output and encoder pulse variation, if detecting, motor is exported
Torque current changes in the first preset range, while encoder pulse remains unchanged, when the two states meet and hold simultaneously
When the continuous time reaches the first preset duration, then it is assumed that elevator control system has reached stabilization, i.e. motor has reached equalising torque.Electricity
Ladder immediately exits from torque compensation mode after reaching stable, is run using normal acceleration and deceleration scheme control elevator.Wherein first is pre-
If duration is related with the size of motor torque and backoff algorithm according to the self weight of elevator, technical staff can according to the actual situation certainly
Row setting, the first preset duration of the present embodiment are set as 0.2s.Wherein the first preset range of torque current variation is generally arranged
First preset range of the torque current variation being arranged in the 3%~5% of Rated motor torque current, the present embodiment is zero to arrive
The 5% of torque current.
Further, which further includes, if elevator controlling is not detected within the first default torque settling time
The motor torque of system reaches equalising torque, then exits torque compensation model, terminates the compensation to motor torque.This is because
The load of elevator is larger in some cases or elevator is in the case where full load, and it is too long to establish duration needed for equalising torque, then
Do not detect that the motor torque of control system reaches the state of equalising torque within the first default torque settling time, this time control
Torque compensation mode processed passes through the first default torque settling time backed off after random, wherein the first default torque settling time was to survey in advance
Elevator establish equalising torque needed for maximum duration, pass through the first default torque settling time backed off after random torque compensation
Mode can guarantee that motor torque of the elevator under any load reaches balance, so that using acceleration and deceleration scheme control
Car slipping phenomenon will not occur for state of elevator stabilization when elevator is run.
Wherein, maximum duration needed for establishing equalising torque as elevator may under or full load conditions unloaded at it,
First default torque settling time obtained by the following method:
Method one: starting elevator under elevator cars with full load state and compensates simultaneously to motor torque, if default second
Duration internal torque curent change is in the first preset range and encoder pulse remains unchanged, then it is assumed that motor torque reaches steady
Determine state, record elevator reaches the duration of stable state from torque compensation is started, and the first default torque settling time was set as
More than or equal to the duration of record.
Method two: starting elevator under elevator no-load state and compensates simultaneously to motor torque, if default second
Duration internal torque curent change is in the first preset range and encoder pulse remains unchanged, then it is assumed that motor torque reaches steady
Determine state, record elevator reaches the duration of stable state from torque compensation is started, and the first default torque settling time was set as
More than or equal to the duration of record.
In other embodiments, when obtaining for the first default torque settling time by the above method one or method two, when
After elevator control system reaches stable state for the first time, in order to guarantee the more accurate of detection, if also further detecting the stable shape
State continue keep third preset duration when, just using the duration of record as be arranged the first default torque settling time benchmark,
Middle third preset duration can be set to identical with the second preset duration.
Preferably, the present embodiment uses method three: it is simultaneously right simultaneously to start elevator under elevator no-load and full load condition respectively
Motor torque compensates, and records elevator respectively from the equalising torque settling time under unloaded and full load condition, chooses two
It is biggish in equalising torque settling time to be used as the first default torque settling time, to ensure the first default torque settling time
Maximum time needed for establishing equalising torque under any loading condition for elevator, it is ensured that elevator passes through under any load
It is attained by the state of equalising torque after the first default torque settling time, avoids elevator that car slipping phenomenon occurs.
Further, in other embodiments, the first default torque settling time may be arranged as being greater than equalising torque
Settling time, but in order to save elevator operating efficiency, it is generally the case that the first default torque settling time was equal to
Equalising torque settling time.Specifically, starting one in the present embodiment while starting elevator under unloaded or full load condition and determining
When device Timer2, when detecting torque current variation in the first preset range and encoder pulse remains unchanged the two
When part is all satisfied, then it is assumed that elevator control system reaches stable state, and the recording timer current time continues timing, works as inspection
When measuring the stable state and continuing for third preset duration, then it is assumed that motor torque establishes balance, then by elevator controlling system
When the duration of the record of timer Timer2 is established as the equalising torque under unloaded or full load condition when system reaches stable state
Between.
Further, in order to improve the operational efficiency of elevator, when detecting that elevator reaches equalising torque, guarantee that elevator reaches
After stable state, control system immediately exits from torque compensation mode and starts normal feed speed control scheme control elevator and carries out just
Normal acceleration and deceleration operation.
Such as Fig. 3, the TO period is that motor torque balances establishment stage, and the T1 period is the elevator normal acceleration and deceleration operation phase,
Reach equilibrium state when the motor torque by TO time elevator control system passes through torque compensation, is then adding within the T1 time
Acceleration and deceleration motion is done under the control of deceleration control model
Wherein, motor torque is compensated to adjust by PI and is completed.Specifically, such as the motor force that Fig. 4 is the present embodiment
Square compensation loop obtains the current feedback speed of encoder since before elevator internal contracting brake opening in real time, by feedback speed and presets
Given speed pass through the first pi regulator input, using the current value of the input and output of the first pi regulator as motor turn
Square electric current, preset given speed is zero in the present embodiment.After elevator internal contracting brake opening real-time detection elevator it is mobile whether be more than
Preset first threshold illustrates electric power if detect that elevator movement is more than preset first threshold in some detection cycle
The adjustment speed of torque is too slow, is not able to satisfy the compensation of the required torque of elevator, then starts the second pi regulator simultaneously simultaneously
Motor torque is compensated, angle when angle and previous compensation which is currently exported with encoder is defeated
Enter, the amount of outputting it is added the torque current as current motor with the output quantity of the first pi regulator, to realize to motor force
Square compensates.Wherein, the first pi regulator and the 2nd PI can also be adjusted according to the amount of movement of elevator and the state of elevator
The PI adjustment parameter of adjuster, such as when detecting that the mobile amount of movement within some period of elevator is more than preset first threshold
When, then illustrate that the adjustment speed of electric power torque is too slow, while starting the second pi regulator, increases the PI of the first pi regulator
Adjustment parameter, if illustrating the PI tune of current first pi regulator and the second pi regulator when detecting that elevator shakes
It is excessive to save parameter setting, motor torque variation is too fast, then needs to reduce current PI adjustment parameter, no to inhibit elevator to shake
Then keep the first pi regulator and the current adjustment parameter of the second pi regulator until start-up course terminates.Wherein motor torque is mended
Repay is periodically, specifically, motor torque compensation is the carrier frequency period for being frequency converter the period, frequency conversion in the present embodiment
Device carrier frequency is 8K, and the carrier frequency period is 125us, therefore it is also 125us in the period that motor torque compensation, which is,.Pass through PI tune
Section can be realized in real time compensates motor torque, so that the torque of motor moves closer to the self weight of elevator, and then reaches
Equilibrium state.
Control method through this embodiment is right in real time using torque compensation mode according to the different loads state of elevator
Motor torque, which nourishes to repay, makes it reach equilibrium state as early as possible, and torque compensation mode is immediately exited from after reaching equilibrium state, uses
Normal feed speed control scheme control elevator motion, so improves electricity while ensure that elevator device stablizes not car slipping
