Fig. 1 is present embodiment system module synoptic diagram.
Embodiment
With reference to figure 1, a kind of straight-bar machines control system comprises main control module, head control module, straight-bar machines control module, display screen, sensor unit, slide cam selector, stepper motor, slide cam selector, servomotor.Sensor unit is connected with main control module, is used for gathering the straight-bar machines working signal and passing to the main control module Intelligent treatment; Main control module, slide cam selector, stepper motor are connected with the head control module, and described main control module is by head control module control slide cam selector, stepper motor action.
Main control module, servomotor are connected with the straight-bar machines control module, and described main control module is by the action of straight-bar machines control module control servomotor; Main control module is connected with display screen, and described master control module controls display screen shows the straight-bar machines duty.
Main control module adopts 32 bit processor S3C2440.The straight-bar machines control module, the head control module adopts Lattice LCMXO1200.Slide cam selector is 8 groups.Stepper motor is 12.Servomotor is two.
Each functions of modules is as follows in the course of work: 8 stepper motors are housed on the head, with the mechanism of stepper motor as control textile density triangle, rotate by the density dish, respectively the density value of needle-bar and front and back system before and after the control.100 sections elective modes of density control; When step actuator receives a pulse signal, it rotates a fixing angle with regard to Driving Stepping Motor by the direction of setting, and its rotation is to move step by step with fixing angle.Can come the pilot angle displacement by the gating pulse number, thereby reach the purpose of accurate location; Can come by the gating pulse frequency speed and the acceleration of the rotation of control step motor simultaneously, thereby reach the purpose of speed governing.
Head is equipped with 8 eight sections digitalized needle selecting machines, and unconventional high frequency control is adopted in its control, makes slide cam selector work more reliable flexibly; The control of the unconventional high frequency of slide cam selector with the electric current control method of copped wave current limliting from the reliable angle of needle selection, adopt the method, can make control mode more stable, avoid the impact of temperature. this be because electromagnet in electromagnetic induction, except magnetic energy increases, do outside the mechanical work, some energy is for generation of heat, and this heat can make the electromagnet temperature raise, and temperature affects resistance sizes, thereby affect size of current, finally affect electromagnetic force, namely affect the reliability of needle selection.
The servomotor 0.01m control flow of shaking table: the straight-bar machines control module receives first the control signal of main control module, processes by analysis the information such as torque, speed, position, interior location output control servomotor after calculation process, gain are adjusted, encoded.The servomotor controller of shaking table has automatic gain and adjusts function and Notch Filter function, but establishment mechanical resonance.Improve the stability of control system debugging software and carry out the internal signal graphic monitoring by the read-write parameter of RS-232 interface, gain adjustment, state demonstration and simulated digital formula oscillograph, thereby reach the control of 0.01m high precision.
Machine comprises automatic stop arrangement, such as the automatic stop etc. of being out of order of broken yarn self-stop, broken needle automatic stop, equipment.Also comprise simultaneously the machine self-checking unit, detect each piece wiring board to each equipment, and show at screen, be very easy to user's maintenance.
Sensor assembly comprises antenna assembly, broken pin test device.When broken yarn self-stop occurs: antenna assembly can come in contact because of spring tension and short-circuit board when broken string occurs, thereby level is dragged down, and signal sends to core CPU by the body plate, and system will carry out the broken yarn self-stop operation.Take-up automatic stop principle of work in the left and right sides is similar to antenna assembly automatic stop principle of work.When the broken needle automatic stop occurs: head has the broken pin test device, the detecting device spring leaf can bump with pin when broken needle occurs, thereby the little tactile switch on the detecting device is unclamped, and produces thus the broken needle signal, send to main control module, sent the order of carrying out broken needle automatic stop operation by main control module.
Adopted large capacity electric board storage facilities in the main control module, made the user store colored type and reach hundreds of.Storage chip model: K4S561632J_UC75: be 256Mbit SDRAM, memory capacity is large, with Guarantee control system enough running memory spaces is arranged.K9F1208U0C: be 64M*8Bits NAND Flash Memory, be used for the control system procedure stores, the user spends the type storage.High speed Flash storage mode, large capacity, parallel interface provides advantage to High-speed Control.CY62128FV30LV: be 1Mbit (128k*8) static RAM, the data such as the real time data when moving in order to preserve machine, parameters, breakpoint.
Power Management Design adopts Switching Power Supply, if the reference mark of straight-bar machines control system has a lot of these reference mark to work simultaneously, needs very powerful power supply, and therefore the timesharing action is carried out at these reference mark on Power Management Design, can greatly reduce power like this.And to different reference mark, power supply is supplied with respectively, avoids the impact of answering the power supply reason to cause between the different reference mark.
Although the utility model is described according to above-described embodiment, the protection domain of invention thought of the present utility model is not limited only to this.
