Field of the Invention The present invention relates to a loom, and more particularly, to a computer readable recording medium on which a loom needle error detection program is recorded so as to be able to detect breaking, cutting, breakage, etc. of loom needle in a reliable and simple manner.
In general, looms are machines for weaving looms using warp and weft yarns and are currently used by most textile, weaving or woolen companies.
The weaving machine needle is attached to the needle barrel inside the weaving machine. Generally, the weaving machine is composed of two needle barrel, and more than 80 needles are installed in one needle barrel.
In the present technology of knitting a fabric using a weaving machine as described above, when there is an abnormality in a needle [needle] which is a main component of a weaving machine, it is checked whether or not the needle It is true.
Therefore, since the manager resides in each loom and confirms the abnormality of the loom, there is a burden on the labor cost of the loom manager and depend on the sense or experience of the manager.
A technique for solving such a conventional problem is known as "IOT platform-based loom monitoring and management system " according to Japanese Patent Registration No. 10-1616413 (published on Apr. 29, 2016).
Since the technology according to the above-mentioned Japanese Patent No. 10-1616413 is described in the patent publication, a detailed description will be omitted.
However, according to the technique of Patent No. 10-1616413, a method of judging the abnormality of the needle is to compare and analyze the image itself. In this case, it is necessary to have a video image for each needle, The implementation of the program for comparative analysis of the image of a needle is costly and complicated and it is difficult to commercialize it realistically.

A computer-readable recording medium having recorded thereon a woven needle error detecting program for execution by a computer of the present invention includes a step (S730) of converting an acquired image into a monochrome image (S730) after performing an image acquisition step (S720) (S740), and the error determination step (S750) compares the current brightness value of the extracted edge image with the reference brightness value so that the current brightness value is greater than the reference brightness value If it is large, it should be treated as a steady state, and if it is dark, it should be treated as an error state.
The computer readable recording medium on which the woven needle error detection program for execution by the computer of the present invention is recorded may further include storing error judgment data in the error judgment step (S750) (S760) (S770), calculating a current average value of the error judgment data stored in the error judgment data storing step (S780), comparing the current average value with a reference average value (S785) (Step S790). If the current average value is greater than the reference average value, it is determined to be a 'needle error', and if not, it is determined that the needle is normal.
A computer readable recording medium having recorded thereon a weft knitted needle error detection program for execution by a computer of the present invention is characterized in that the step (S710) of setting the needle area comprises: displaying a video image of a needle (Step S810), a step S820 of inputting a region setting data value, and a step S820 of inputting a region setting data value, And a number of needle areas corresponding to the number of needles is set (S830).
The computer readable recording medium on which the above-described woven needle error detecting program of the present invention is recorded has the following effects.
First, when there is an error such as when the needle of the loom is in a deformed state with warping or when it is cut or broken, it is effective to set the needle area and to detect the needle error based on the brightness difference in each area .

The step (S630) of detecting whether or not there is an needle with the error is performed by execution of a needle error detecting program. Specifically, the needle error detecting program is performed in the following order.
First, a step S710 is performed in which the
The step of setting the needle area (S710) is implemented by sequentially performing the following steps.
The
Thereafter, step S820 in which the area setting data value is input is performed.
The area setting data value may be input to the
When the area setting terminal is connected to the
The area setting data value is, for example, a reference coordinate value, a height and a width value, and the number of areas.
When the reference coordinate value (e.g., coordinate value of the upper left corner), the height of the entire area, the width of the entire area, and the number of areas (for example, 40 as shown in FIG. 6) are input, the area is set to match the image.
FIG. 6 shows an example of setting this area to the user through the display unit.
As shown in FIG. 6, there are 40
In the needle area on the upper side, there are three black portions indicated by red lines. In this needle area, the needles are lost and appear black. In the case of this needle area, the binary data will be processed as zero.
As described above, when the area setting data value is input, the number of needle areas corresponding to the number of needles is set one-to-one with each needle of the needle image image (S830).
As described above, when the needle area is set, the
The image corresponding to the needle area is acquired by matching the current image of the needle taken by the image pickup device 120 (hereinafter referred to as the current needle image) and the
After the step of acquiring the image (S720), the step of converting the acquired image into the monochrome image (S730) is performed.
The step of extracting the edge of the converted monochrome image (S740) is performed.
This is to make the image more vivid and to extract the current brightness value accurately.
If the current brightness value is larger than the reference brightness value, it is determined that the current brightness value is normal. If the current brightness value is smaller than the reference brightness value, it is determined that the current brightness value is an error (S750) .
In the error determination step S750, the current brightness value of the extracted edge image is compared with the reference brightness value. If the current brightness value is larger than the reference brightness value, the error is determined to be a normal state (binary data 1) Data 0).
The error determination in step S750 determines whether there is an error with only one image value.
However, in order to increase the reliability of judgment, it is performed a plurality of times (for example, 30 times per minute), and an error is judged based on the average value of the plurality of performances. Hereinafter, this method will be described.
The step S760 of storing the error determination data (binary data of the normal state and the error state) in the error determination step S750 is performed.
The steps S720 to S760 are repeated n times (n: 30, for example, natural number greater than 2) in a plurality of circuits (S770).
The current average value of the error judgment data stored in the error judgment data storing step is calculated (S780).
Then, the current average value and the reference average value are compared (S785).
If the current average value is greater than the reference average value, it is determined to be a 'needle error', and if not, it is determined that the needle is normal (S790).
