Description

The operation speed command controlling apparatus of elevator and method
The present invention relates to the operation speed command controlling apparatus and the method for elevator, particularly relate to elevator speed CCE and development of method, it can detect and have or not the passenger in lift car, and detect elevator whether the emergency state takes place, produce suitable running velocity command signal thus, thereby reduce the wait time of passenger on floor, improve lift car and stop sensation, and time of run and time of run error minimum that response is called out.
Usually, on delivery passenger or the luggage/lift car of motion down, the lift car that moves along the car movable passageway is connected to a counterweight by hawser.The bonded assembly hawser is along with by propulsive effort that DC machine, induction motor or linear electric motors produced and be wound and unclamp like this.Can adopt the hydraulic machinery winding and unclamp hawser.
Fig. 1 is the schematic block diagram of existing operation speed command controlling apparatus.
As shown in Fig. 1 figure, lift car 105 is used to deliver passenger or luggage.With hawser 108 counterweight 107 is connected to lift car 105, is used for the weight of balance lift car 105, and reduce the consumption of current of system.The driver element 106 that comprises cylinder and motor (not shown) is utilized for system provides propulsive effort, is connected hawser 108 between lift car 105 and the counterweight 107 by on cylinder.The effect of a position detector 104 is the current locations with the motor (not shown) cooperative lift car 105 of driver element 106.Car call button dish 109 and floor call push button pad 110 are installed in the lift car 105 respectively and on the floor, the calling that is used for requiring according to the passenger produces car call signal or floor call sign.Operation order administrative unit 100 is used in many callings of passenger priority resolution and calls out, and checks the secrecy system of elevator when car call data or floor call data are sent to system by order wire 111 and 112 all sidedly.The effect of operating speed command generator 101 be in an acceleration phase with the position of the control loop Collaborative Control lift car of an opening, make lift car 105 can arrive the floor that produces priority call, detected car position value P (KT) in the decelerating phase passes through closed control loop controlled feedback position according to car position detector 104, and with utilizing an adder 101a to produce operating speed command voltage V (KT).The effect of electric power amplifier 102 is that electric power is amplified to predetermined level, thereby the operating speed command voltage V (KT) that produces with operating speed command generator 101 makes lift car 105 be activated the control of the motor of unit 106.
Following with reference to Fig. 2 and the habitual elevator operation speed command control method of 3 explanations.
At first, when waiting when the passenger on the floor or the passenger in lift car 105 call out lift car 105 or call out a floor by pressing floor call button 110 or car call button 109, just a floor call data and car call data in operation order administrative unit 100, have been registered by one of two order wires 111 and 112.
Step ST1 in Fig. 2, operation order administrative unit 100 checks that in by the calling of pressing the existing registration that floor call button 110 and car call button 109 produce which calling has preceence, and be that operating speed command generator 101 produces an operating speed command signal, so that at first execution priority is called out, and move a corresponding lift car according to the command signal of such generation.
In step ST2, check priority call in the calling that operating speed command generator 101 will be registered from operation order administrative unit 100, and check the operating speed command status that lift car 105 is current, also will detect lift car 105 current operating speed command status and whether relate to acceleration mode or deceleration regime.
According to the testing result among the step ST2, if lift car 105 current operational speed relate to acceleration mode or state at the uniform velocity, operating speed command generator 101 just receives about acceleration or control command signal at the uniform velocity in step ST3, and uses habitual acceleration diagram to obtain operating speed command value V (KT) according to the formula that will explain later on (1).According to the testing result among the step ST2, if current operational speed relates to the decelerating phase, operating speed command generator 101 just receives the control command about deceleration-operation, and obtains an operating speed command value according to the formula that will explain later on (2).The operating speed command value that obtains like this in step ST3 and ST4 is provided for electric power amplifier 102.
Specifically, from following formula (1) as seen, the position of operating speed command generator 101 control lift cars, so that produce operating speed instruction V (KT) according to stage schedule time of process, this time phase and lift car 105 current acceleration phase and at the uniform velocity in the stage position and the operating speed according to the control loop of opening have nothing to do.In addition, feedback position is controlled, thereby can produce operating speed instruction V (KT) according to remaining distance, this Distance Remaining is according to the distance of the detected lift car 105 current location value P (KT) of closed control loop to the position that the time of run error occurs, so that reduce the time of run error in decelerating phase by car position detector 104.
Figure A9612274500061
α wherein 1The expression maximum acceleration value, K represents to quicken and stage at the uniform velocity, and its value for K ∈ 1,2,3,4}.
α wherein 2The expression maximum deceleration value, K represents the decelerating phase, and its value is that { 5,6,7}, T represent a control cycle to K ∈, " dest " expression run duration error position, and the current location of P (KT) expression lift car 105.
Specifically, as shown in Figure 3, operating speed command value V (KT) determines according to time base operating speed figure, this velocity diagram increases along with elapsed time, comprising acceleration phase K1 according to habitual acceleration diagram, the acceleration phase of even acceleration phase K2 and acceleration phase K3 and at the uniform velocity haveing nothing to do with operating speed command value V (KT) within the stage K4.Operating speed command value V (KT) is sent as the operating speed command value.In addition, operating speed command value V (KT) determines according to Distance Remaining and time of run error position that the current location from lift car 105 begins, so that comprising decelerating phase K5, at the uniform velocity reduce the time of run error in the decelerating phase of stage k6 and decelerating phase K7.
In addition, as seen, the time during the acceleration phase K1 (period T 1) is fixed on a predetermined value from formula (1) and (2), and irrelevant with car call and floor call, such operating speed command value V (KT) is provided for electric power amplifier 102.
In other words, the electric signal that is produced by operating speed command generator 101 in each cycle (T1 to T7) is very weak.Therefore, since this signal can not direct drive driver element 106 motor (not shown) or hydraulic efficiency gear (not shown), will be amplified to a predetermined level to the operating speed command value V (KT) that operating speed command generator 101 produces by electric power amplifier 102, and the value of amplifying be offered the motor or the hydraulic efficiency gear of driver element 106.
In the step ST5 of Fig. 2, the motor of driver element 106 or hydraulic efficiency gear are driven according to the operating speed command value from electric power amplifier 102.Like this, lift car 105 moves to predetermined destination with regard to cooperating hawser 108.When the elevator car arrives destination, just finish the operation of elevator.
Yet, as mentioned above, as illustrated in fig. 1 and 2, according to the operating speed instruction that produces in habitual elevator operation speed command control setup and the method, position control is to carry out according to open control loop, the instruction of wherein operating speed produces according to elapsed time in predefined phase, with acceleration phase K1 to K3 with at the uniform velocity lift car current location and the operating speed in the stage K4 is irrelevant.In addition, feedback position control is carried out according to closed loop control, the instruction of wherein operating speed is to determine to the Distance Remaining of time of run error according to beginning from the lift car current location, so that reduce the run duration error at K5 in the decelerating phase of K7.
Therefore, if from acceleration phase K1 to K3 or at the uniform velocity stage K4 to the stage of decelerating phase K5 to K7 variation has taken place, the operating system of elevator will change.Because the speed of electric power amplifier and torque are at acceleration phase K1 to K3 or at the uniform velocity differ from one another among the stage K4 with among the decelerating phase K5 to K7, vibration will appear.In addition, high operating speed is poor occurring each other, thereby causes taking of lift car to feel under the weather.In addition, very big and do not have the error except the motor output that drives lift car when the idle condition, when lift car 105 from acceleration phase with at the uniform velocity stage to the decelerating phase changes its running state during the stage, because can not satisfying, the operating system of lift car 105 quickens and the time base velocity diagram in the stage at the uniform velocity, in order to compensate the positional error of accumulative total, must carry out deceleration-operation, or must postpone time of run significantly based on calling, that does not consider lift car in this course takes sensation and time of run error.
Moreover, in the operating speed command generator,, and no matter have or not the passenger in the lift car, so just can make taking of lift car feel to make moderate progress because control cycle (time T 1) in acceleration phase K1 is fixed on the fixed value.When in lift car, not having the passenger or the emergency state occurring, can produce high-revolving velocity diagram, thereby can carry out passenger's car services request apace; Yet, because the time durations of acceleration phase is limited, will produce the operating speed instruction of low efficiency, the operating efficiency of lift car is descended.
Therefore, purpose of the present invention provides a kind of operating speed CCE for elevator exactly, and it has overcome the problem that exists in the habitual operating speed CCE.
Another object of the present invention is to provide a kind of improved operating order control setup and method for elevator, thereby can shorten the wait time of passenger on floor, improve the sensation of taking of lift car, and make based on the time of run and the time of run error minimum of calling out, in lift car, have or not passenger and elevator the emergency state whether to occur by detection therein and produce a suitable operating speed command signal.
To achieve these goals, the present invention provides a kind of operating speed CCE for elevator, it comprises car call button and the floor call button that is used to produce car call signal or floor call sign, an operation order administrative unit, be used for determining to send the operating speed figure of instruction to lift car, in the middle of calling, determine a priority call by car call button and the registration of floor call button, and produce an operating speed figure, an operating speed command generator, be used for according to according to the calling of operation order administrative unit registration with from the car call of floor or the operating speed figure that generates from the priority call of the floor call of car, from the acceleration diagram of an operational phase setting, determine a Jerk acceleration/accel and a response time, obtain the reference velocity distribution graph in a stage, and produce the proportional operating order of difference with the detected current elevator car position value of the reference position distribution graph of integration acquisition by the reference velocity distribution graph and car position detector, an electric power amplifier, be used for the amplifieroperation speed value, so that operate the electric machine in the driver element that comprises cylinder and motor, make lift car according to the work of reference velocity distribution graph.

At step ST101 in ST105, if having one from the car call of floor and not from the floor call of car, the time T 1 during the prolongation acceleration phase K1 in step ST107 just, and make lift car turn back to reference floor to enter stand-by state.
With different among the step ST100, when if the operation mode of elevator is in fire pattern or fire fighting pattern, just in step ST109, prolong the time T 1 during the acceleration phase K1, do not consider therein and take sensation, and it is irrelevant with car call and floor call, produce the operating speed distribution graph then, thereby make the passenger in the building that elevator is housed to flee from the building soon.
Specifically, according to the stage K1 shown in Fig. 3, K2 and K3 area sum can not surpass the condition of normal speed MAX-V, and the upper limit of the time T 1 during the acceleration phase K1 shown in Figure 3 can be represented with following formula (6).
The curve of Fig. 8 A and 8B is used to illustrate elevator position distribution graph of the present invention and elevator acceleration profile.Adopting the elevator normal speed in the present embodiment is the condition of 120m/mim.If the Jerk acceleration/accel J in the acceleration diagram shown in Figure 3 is fixed on 0.5m/sec 3,, just may obtain the result shown in Fig. 8 A because the limit value of the time T 1 that provides in the formula (6) is two seconds.Specifically, Fig. 8 A has represented a kind of Simulation result, and wherein the time T 1 during the acceleration phase K1 was set to one second and 0.5 second, and they all were within two seconds.When time T1 was 0.5 second, lift car moves 20m need be with 18.5 seconds, and when time T1 was one second, lift car moves same distance to be needed with 15 seconds.
As mentioned above, if the condition according to lift car produces different operating speed instructions, just can make service time the shortest, and owing to can predict service time, just can improve the operating efficiency of lift car significantly, can also constitute the cluster management system of a plurality of elevators preferably, and improve and take sensation, the time of run error is reduced to minimum.
In addition, if do not have the passenger in the elevator or the emergency state has taken place, can also make the wait time of passenger on floor reduce to the shortest by the time T 1 during the change acceleration phase K1.
