Embodiment
At first, the CANopen agreement that is adopted is briefly introduced.CANopen is the application layer communication standard by the distributed automatic system of CiA formulation.Each data of CANopen protocol transmission all are the objects of a certain certain kinds, and CANopen has defined 4 class communication objects: 1. network management NMT, be used for the network host node to from monitoring nodes and management, and control is from the duty of node; 2. process data object PDO is used for the real time data that transmission network is operated, the control variable of transmission system; 3. Service Data Object SDO is used for transmission node parameter and structure dependent configuration data, finishes parameter configuration, the configuration of system, the form of assignment procedure data PDO; 4. specific function object SFO is used for synchronous, as to meet an urgent need indication and time mark special object, cooperates three kinds of above-mentioned communications.
Below with reference to Figure of description, describe in detail a preferable embodiment of the present utility model.Circuit connection diagram such as Fig. 1 adopt Schneider Twido Programmable Logic Controller, and 2 number of turns detecting devices (2), the usefulness that tests the speed photoelectric encoder (12) signal insert high-speed counter.Tension pick-up (5), temperature sensor (10) signal insert the analog quantity load module.Expanded 1 CANopen communication module simultaneously.
Adopt Schneider XBTG touch-screen, have the picture and text Presentation Function, can show artwork, procedure parameter, setting tension value, system running state, failure message.Also can finish various system operations, reduce various instrument and control knob, the quantity of pilot lamp and the area of guidance panel on the guidance panel.
Structural plan such as Fig. 2 mainly comprise cloth beam (1), number of turns detecting device (2), cloth beam (3), speed reduction unit (4), tension pick-up (5), jockey pulley (6), fabric (7), motor 1 (8), motor 2 (9), temperature sensor (10), fabric guide roll (11), photoelectric encoder (12), staining bath (13).
The utility model has into cloth, dyeing, washes and goes out operating modes such as cloth, when advancing cloth, fabric (7) is wound on the cloth beam (1) from the turnover cloth holder, and it is long to count the coiling number of turns and cloth simultaneously.During dyeing, advanced dyestuff, heat, start frequency converter then, make (3) one of cloth beam (1) and cloth beams be in the rolling state, another is in the state of unreeling.Arrow shows the traffic direction of cloth among Fig. 2, and motor 2 (9) is a winding motor during solid line direction, and motor 1 (8) is to unreel motor, counts the coiling number of turns, long, the dyeing road number of cloth simultaneously.After the wind-up roll number of turns reaches setting value, stop this direction operation, change the traffic direction of cloth automatically, at this moment motor 1 (8) becomes winding motor, and motor 2 (9) is to unreel motor.When dyeing road number reaches when setting the road and counting, entering the swing operation automatically is that low speed back and forth moves.Can stop as pressing stop button this moment, and automatic drain.During washing, intake earlier, heat, spray, start frequency converter then, the method for operation is analogous to dyeing.When going out cloth, make cloth beam (3) rolling by the frequency converter drive motor, cloth beam (1) unreels.When going out the cloth end, remove parameters such as the number of turns, cloth length, road number.
Control strategy of the present utility model is as follows: Alternating Current Governor System has advantages such as energy-saving and cost-reducing, that minimizing is keeped in repair, price is low, adopts two frequency conversion closed-loop controls, and permanent tension force constant linear velocity online feedback control controls to minimum to speed and tension fluctuation.Because of the internal control current interference to producing phenomenons such as driving, brake be out of control, be the problem that general frequency conversion dye jigger often occurs, stable control program of the present utility model has solved during dyeing was produced in the past problems such as insurmountable driving, has improved product quality.Control function is finished by programmable controller program; The control of wind-up roll is constant linear velocity PID regulator; Let off roll adopts tandem control, and interior ring is a tension link, and outer shroud is a speed ring, control loop block diagram such as Fig. 3.
The control of tension force realizes that by the adjusting of speed linear velocity signal V comes from the photoelectric encoder (12) of fabric guide roll (11), has reflected the actual linear velocity of cloth operation.The coil diameter computing unit is finished the coil diameter calculation task.Δ V is tension adjustment output, as the linear velocity correction.ω
1Be the angular speed calculation value, guaranteed that motor regulates rotating speed and add the tension adjustment influence value by the coil diameter that calculates.ω is final actual output angle speed, feeds back to the coil diameter computing unit and participates in coil diameter calculating.For the computing of Δ V part, adopted the PI algorithm.Because motor side is unkitted speed measuring device, motor speed ω reads current rotating speed output by the CANopen communication from the frequency converter side.
During concrete enforcement, should carry out Design of System Software.Programmable controller program is mainly by forming with lower module:
1. master routine.Finish the organization task of The whole control program.
2.CANopen communication subroutine.Finish reception or transmission between Programmable Logic Controller main website and each slave station, data are changed according to the CANopen agreement.
3. logic control subroutine.The logical relation of mainly finishing in the whole process flow is handled.
4. temperature control subprogram.The control of staining bath temperature adopts the digital PID function of Programmable Logic Controller to form temperature regulator.
5. fault handling subroutine.Be used to handle various failure messages, be used for warning, parking etc.
Dye jigger does not store up snubber assemblys such as cloth, tension bracket in operational process, the subtle change of speed just may cause the great changes of tension force, so the real-time of control system is had relatively high expectations, if any delay, very easily causes system oscillation in communication process.Adopt the CANopen communication modes, the status word of frequency converter, command word, velocity setting value, actual speed value of feedback etc. are configured to the PDO mode, in real time the operation values in the Programmable Logic Controller is transferred in the frequency converter, thereby change the running speed of motor rapidly.
As Fig. 4, CANopen communication subroutine program: at first take out status word, judge then; If order is finished initialized process step, then make the CANopen communication transfer to " initially " state from " application program resets "; If judge that status word is that fault resets, then make the CANopen communication transfer to " application program resets " state from " stopping "; If judge to receive peripheral operation, then send corresponding command word, make the CANopen communication transfer to " operation " state from " pre-operation ", carry out control corresponding.
Except that the described technical characterictic of instructions, be the known technology of those skilled in the art.
