Abstract
The content of this paper is about the design of industrial sewing machine’s human-machine interface using touch keys. The reason of using the touch keys is mainly to conform to the current market’s requirement and using touch keys has a lot of advantages which we can’t get if using normal touch keys. So this design can be accepted more easily by users. The structure of the hardware in this design is clear. The AT89c55 has been used as a controller. The touch chip QT1080 has been used as the input device. The role of the HT1621 in this design is LCD driver. And the communication we has used in this design is RS-485 which has relatively high reliability. We also have used X5045 to play a supporting role. All above make the design more complete and more feasible. The software in this design mainly according to the Industrial Sewing Machine’s function we need and the hardware design. So we designed a highly reliable program which can carry out the desired function and can mach the hardware design.
