Description of drawings
Further specify the utility model below in conjunction with the drawings and specific embodiments.
Fig. 1 is a structural representation of the present utility model.
Among the figure, 1. host computer; 2. bus; 3. controller; 4. motor; 5. spindle; 6. holding wire; 7. control line.
The specific embodiment
Further specify below in conjunction with accompanying drawing, and the related scope of unrestricted the utility model.
Referring to shown in Figure 1, the utility model comprises a host computer 1, some controllers 3, some motors 4, some spindles 5 and bus 2, described host computer 1 is connected with some controllers 3 by described bus 2, be provided with holding wire 6 between every described controller 3 and the described motor 4, between every motor 4 and spindle 5, be provided with a control line 7.Each spindle 5 is driven by a motor 4, and a motor 4 is driven by controller 3, described motor 4 is brushless, permanentlies, described host computer 1 comprises hardware system and software systems, described software systems comprise main control software, host computer 1 is issued to each controller 3 by bus 2 with run parameter, and the running status of each controller 3 also can feed back to host computer 1 by bus 2.Because spindle 5 has CPU control, the monitoring of the running status of single spindle 5 becomes possibility.Current and the statistical informations such as historic state, output and warning message of each spindle 5 operation are concentrated by bus 2 and are transported to host computer 1, and host computer 1 adopts the database centralized management.Therefore each spindle 5 has independently motor control unit; This motor 4 is to have polyphase windings, and a plurality of magnetic field position sensors are provided with many group electronic commutations unit.By bus 2, hundreds of motors of whole system 4 receive the high-speed transfer control instruction, the coordinated movement of various economic factors simultaneously, the differential curve tracking technique is adopted in the speed control of the multiple electric motors 4 that the utility model is included, realizes with spindle 5 and 5 speed running precisions of spindle being 0.1%-0.2%.
Each independently the control module of controller 3 provide signal according to shift knob, sensor, the link that tests the speed, current foldback circuit etc.; the main control software of host computer 1 has been realized the control function of motor 4, comprises starting/stop, just/counter-rotating, speed closed loop control etc.The course of work is, when passage has yarn, system normally twists motion; Passage does not have yarn, feeds back to the unit CPU of single spindle 5 after sensor is found out, and CPU is through the electromagnetic valve of the single spindle 5 of technology time-delay back triggering, and the solenoid control cylinder is at the special process lifting cylinder of supplying gas in the time period, and cylinder lifts the tube yarn.System enters visits the yarn wait state, enters Control Circulation next time.In two-for-one twister control, can be connected with nearly 160 spindle Unit 5; Each unit has the motor 4 of independent twisting, and there is independently SERVO CONTROL drive system each unit; Electric power system independently; The utlity model has functions such as error protection, power down protection, overcurrent protection.Unique control device 3 except that SERVO CONTROL speed, also has special interface circuit, in order to realize start button, stop button, yarn break sensor interface, solenoid valve interface, alarm lamp or the like.The motion speed of service of motor 4 is steady, and precision is higher.Can in 3S, reach the technology spinning speed of the highest 15000RPM.Running medium velocity control accuracy is: ± 0.1.%.If can not reach running accuracy in 30 seconds, can report to the police automatically and stop ingot.Fast braking or dead electricity braking time 3-5 second.The communication function of bus possesses under any working environment, when host computer 1 time biography technological parameter or controller 3 are uploaded the running status of each spindle, does not lose data, does not make mistakes, and it is perfectly safe to accomplish; Have self-diagnostic function: abnormality (communication abnormality, velocity perturbation big etc.) occurring can autostop, and notice host computer 1.Bus 2 in the system is the CAN bus, and the CAN bus is a kind of fieldbus with high reliability.As the Event triggered agreement, the CAN bus can make up the distributed system of many master access very easily.
The node address of host computer 1 is defaulted as 0, and the node address scope of the controller 3 of each spindle 5 is 1-160, by DIP device a unique address is set.Host computer 1 sends to each controller 3 with mass-sending or point-to-point mode with various technological parameters, and controller 3 sends to host computer 1 in point-to-point mode with the running status and the failure code of motor 4.The signal that host computer 1 provides according to shift knob, sensor, the link that tests the speed, current foldback circuit etc., main control software has been realized the control function of motor 4, comprises starting/stop, just/counter-rotating, speed closed loop control etc.
The utility model advantage compared with prior art is:
The utility model not only makes head intelligent control, automation, and makes single ingot operation high level of synchronization, consistent, and then promotes the electric automatization level of whole set equipment.
The accurately motor 4 high speed steady runnings of the single spindle 5 of control become 10 times to reduce by 5 deviates of spindle, effectively control twisting unevenness, fundamentally the lifting means technic index;
