Abstract
The invention discloses a method for controlling the warp tension of a sample weaving machine. An ARM (Advanced RISC Machines) embedded processor is a main controller, and a warp-pacing controller is connected with the main controller. A pressure sensor is used for receiving the pressure of warp through a pressure roller, the pressure sensor is used for sending detected tension data to the main controller after being connected with an analog-digital converter, and the main controller is used for comparing the tension data with a set threshold value to determine whether the warp is sent or not. A reeling controller is connected with the main controller, and the reeling of the reeling controller is realized by the main controller according to a set weft-density value in each cycle period. The main controller is connected with an IO (Input/Output) driving circuit and a working power supply. The method has the advantages that the sample weft-density application range is wide, start-up marks can be avoided, the function of changing the weft density can also be realized, and the like.
Description
Technical field
The invention belongs to the electrical integrated field of weaving loom, relate to a kind of warp tension control method, particularly a kind of sample loom warp tension control method.
Background technology
It is a major reason that affects sample quality and yield that the tension force of sample loom warp thread when weaving is controlled.The even tension of General Requirements warp thread and being as far as possible consistent in weaving process.The factor that affects warp tension is a lot, but most importantly wants to control in time the variation of tension force, and feeds back to loom control system adjustment.Loom warp tension control device is generally comprised of mechanical part and electrical equipment detecting element two parts, detection position setting and approach switch that current subject matter is mechanical part are reasonable not as selecting of detecting element, the tension value fluctuation range detecting is larger, cause warp let-off size to control difficulty, affect sample quality.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art, a kind of warp tension control method for sample loom is provided.
ARM flush bonding processor is master controller, and warp let-off controller is connected with master controller.Pressure sensor receives the pressure of warp thread by pressure roll, after pressure sensor is connected with analog-digital converter, by the tension data detecting, send master controller, and master controller compares tension data and Threshold value to determine the whether warp let-off.Batch controller and be connected with master controller, batch controller and realize and batching according to each cycle period of filling density settings by master controller.Master controller is connected with IO drive circuit and working power.
What control method of the present invention was used is Adaptive PID Control technology, by the analog quantity of warp thread pressure is quantized, the system Threshold value comparisons such as loom operational factor such as loom preset parameter and the real-time filling density value of sample loom, the speed of a motor vehicle per sample, finally draw sample loom tension force control parameter, reach desirable sample loom tension force and control effect.
Usefulness of the present invention is: the warp tension control method of the sample loom that this discovery provides, the tension stability of sample loom, filling density is even, wide accommodation, the detection position setting and the approach switch that have overcome mechanical part are reasonable not as selecting of detecting element, the tension value fluctuation range detecting is larger, causes warp let-off size to control difficulty, affects sample quality.
Accompanying drawing explanation
Fig. 1 is for woven warp tension control system circuit block diagram;
The specific embodiment
A kind of warp tension control method for sample loom provided by the invention, the present invention is described in more detail with reference to the accompanying drawings.
As shown in Figure 1, for the warp tension control system of sample fabric manufacture equipment, ARM flush bonding processor is master controller, and warp let-off controller is connected with master controller.Pressure sensor receives the pressure of warp thread by pressure roll, at a plurality of crucial moments in a shuttle cycle, monitor warp tension, pressure sensor is connected with analog-digital converter, control system converts through A/D the tension signal being detected by sensor to data signal, calculate the mean value of one-period internal tension, this mean value send master controller, and master controller compares tension data and Threshold value to determine the whether warp let-off.As require warp let-off controller by certain control strategy, to calculate, obtain the pulse signal of some, with this control the warp let-off and curling motor operation, parking, rotating speed is controlled and turn to etc., guarantees constant loom warp tension.
