The man-machine interface designed by the upper computer controls the operation mode of the lower computer system and is an important part of the software design. The interface is written by Visual C++ graphical design software.

The selection of pattern patterns, data conversion and transmission, selection of loop pile and cut pile patterns, selection of the working mode of the tufting machine—manual or automatic, and display of the working conditions of the tufting machine are completed through the man-machine interface. The man-machine interface is simple and easy to learn, all in the form of dialog boxes, which is convenient for workers and technicians to operate.
Data conversion is to convert the color information of the bitmap into binary data 0 and 1 required by the control system. The image contains two colors, each color represents a working state, a loop of velvet or a cut velvet, and different colors are used. different numbers instead. The bitmap information is transmitted to the lower computer through data conversion, and the lower computer controls the conveying of the yarn according to the pattern information, thereby producing the carpet that meets the requirements.
The communication system is the lifeline connecting the upper computer and the lower computer. Only when the communication line is unblocked can the normal work be ensured, and the bitmap data can be transmitted, and the data of the lower computer can also be transmitted to the interface, and the work of the tufting machine can be displayed correctly. state. The upper computer transmits the bitmap control data to the lower computer at one time, and the lower computer will transmit the working condition of the tufting machine to the upper computer interface in real time.

The host computer is divided into three parts according to different functions and structures. The operation interface completes the sending of operation instructions, the data conversion completes the conversion of bitmap images, and the communication system ensures data transmission. The division of labor between each part is clear and closely integrated, which ensures the normal operation of the entire host computer system.
