Specific embodiment
Further illustrate below in conjunction with accompanying drawing, not limit scope involved in the present invention.
It is shown in Figure 1, the present invention includes host computer 1, some controllers 3, some motors 4, some spindles 5 and a bus 2, the host computer 1 is connected by the bus 2 with some controllers 3, per holding wire 6 is provided between controller described in platform 3 and the motor 4, a control line 7 is provided between every motor 4 and spindle 5.Each spindle 5 is driven by a motor 4, and a motor 4 is driven by controller 3, the motor 4 is brushless, permanently, the host computer 1 includes hardware system and software systems, the software systems include main control software, run parameter is issued to each controller 3 by host computer 1 by bus 2, and the running status of each controller 3 can also feed back to host computer 1 by bus 2.Because spindle 5 is with CPU controls, the monitoring of the running status of single spindle 5 is possibly realized.The statistical informations such as current and historic state, yield and warning message that each spindle 5 runs are concentrated by bus 2 and are transported to host computer 1, and host computer 1 is managed using centralized database.Therefore each spindle 5 has independent motor control unit；This motor 4 is multiple magnetic field position sensors with polyphase windings, is provided with multigroup electronic commutation unit.By bus 2, whole system hundreds motor 4 receives high-speed transfer control instruction, the coordinated movement of various economic factors simultaneously, the speeds control of the multiple electric motors 4 included by the present invention adopts differential curve tracking technique, realizes that with speed running precision between spindle 5 and spindle 5 be 0.1%-0.2%.
The control unit of each independent controller 3 provides signal according to shift knob, sensor, the link that tests the speed, current foldback circuit etc.; the main control software of host computer 1 realizes the control function of motor 4, including start/stop, positive/negative turn, velocity close-loop control etc..The course of work is that, when passage has yarn, system normally twists motion；Without yarn, sensor feeds back to the unit CPU of single spindle 5 to passage after finding out, and CPU triggers the magnetic valve of single spindle 5 Jing after technique time delay, and solenoid valve control cylinder is supplied gas lifting cylinder within the special process time period, and cylinder lifts on cylinder yarn.System is entered visits yarn wait state, enters control circulation next time.In two-for-one twister control, up to 160 units of spindle 5 can be connected with；Each unit has the motor 4 of independent twisting, and each unit has independent SERVO CONTROL drive system；Independent electric power system；The present invention has the functions such as error protection, power down protection, overcurrent protection.Unique controller 3, in addition to servo control speed, also special interface circuit, to realize start button, stop button, yarn break sensor interface, solenoid valve interface, alarm lamp etc..The motion speed of service of motor 4 is steady, and precision is higher.The technique spinning speed of highest 15000RPM can be reached in 3S.Running medium velocity control accuracy is：±0.1.%.If can not reach within 30 seconds running accuracy, meeting automatic alarm stops ingot.Fast braking or dead electricity braking time 3-5 second.The communication function of bus possesses under any working environment, and host computer 1 passes down technological parameter or when controller 3 uploads the running status of each spindle, does not lose data, does not make mistakes, and accomplishes perfectly safe；With self-diagnostic function：There is abnormality（Communication abnormality, velocity perturbation are big etc.）Energy autostop, and notify host computer 1.Bus 2 in system is CAN buses, and CAN buses are a kind of fieldbus with high reliability.Used as event-triggered protocols, CAN buses can very easily build the distributed system of many master access.
Bus 2 in system can also be RS-485 bus structures.
Bus 2 in system can also be industry ethernet structure, so, network cable transmission signal be utilized between host computer 1 and controller 3.
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, and by DIP device a unique address is arranged.Various technological parameters are sent to each controller 3 by host computer 1 with mass-sending or point-to-point mode, and the running status and failure code of motor 4 are sent to host computer 1 by controller 3 in point-to-point mode.According to the signal of the offer such as shift knob, sensor, the link that tests the speed, current foldback circuit, main control software realizes the control function of motor 4 to host computer 1, including start/stop, positive/negative turn, velocity close-loop control etc..
Present invention advantage compared with prior art is：
The present invention not only makes head intelligent control, automation, and makes single ingot operation high level of synchronization, consistent, and then lifts the electric automatization level of whole set equipment.
The high speed steady running of motor 4 of the single spindle 5 of precise control, into 10 times of reduction by 5 deviations of spindle, effective control twisting unevenness, fundamentally lifting means technic index；
The CPU of single spindle 5 communicatively control instruction transmission, the monitoring of the running status of single spindle 5 is possibly realized；Kinds of processes setting is more convenient.The information such as the speed of service, output statistics, the malfunction of single spindle 5 can be generalized machine 1 and collect and process, and then form the form for meeting technique needs.
