[Abstract]:Pneumatic marking technology is to use numerical control equipment to control the printing needle according to the edited characters or graphics track, while pneumatic equipment control high-pressure gas high-frequency impact printing needle, A marking technique for forming characters or graphics consisting of a dense lattice on the surface of a workpiece. Pneumatic marking machine system is composed of mechanical, electronic and numerical control technology, which is widely used in industry. In recent years, with the development of computer technology, USB2.0 interface has been popularized by virtue of its many advantages. Therefore, it is inevitable to develop pneumatic marking machine system based on USB2.0 high-speed interface to improve the competitiveness of enterprise products. In this paper, a pneumatic marking machine system based on high speed interface of USB2.0 is put forward and implemented according to the actual needs of the subject. This paper introduces the solution and implementation technology of the system from two aspects: hardware and software. The upper computer client software is developed by Visual Basic, the USB function driver is developed by DriverStudio tool software, and the dynamic link library (DLL); developed by Visual C uses Altium Designer software to make printed circuit board. The USB2.0 chip CY7C68013A produced by CYPRESS company is used to realize the data transmission, the AT89S52 single chip computer is used to complete the NC interpolation operation, the motion control of step motor and I / O processing. In the Keil uVision4 development environment, the data communication software of CY7C68013A and the NC interpolation and I / O processing software of AT89S52 are programmed with C51 language based on single chip computer. Finally, the on-line debugging of the system is carried out. Compared with the traditional parallel interface, the self-designed USB2.0 interface system has the advantages of strong anti-interference ability, high integration of hardware circuit, low power consumption, low cost, support for hot plug and play, plug and play. USB data transmission adopts the Slave FIFO mode of CY7C68013A, the data transmission speed is fast, and the data transmission can be completed stably. The communication between USB2.0 data transmission module and PC computer is encapsulated by general dynamic function library. This module is easy to use and easy to use in different programming platforms. It is easy to upgrade the system.
