Abstract:

As for the status quo of the industrial printing technology, the paper introduces an industrial 3-coordinate automatic printing machine, which uses th e monolithic integrated circuit as the main controlling machine. It also studies the interface circuit between CPU and the peripherals as well as the so  ftware design. The structure of this air-operated printing machine system is simple, low-cost, and stable.

Key words: pneumatic print machine, AT89S52 MCU, stepping motor, high-frequency valve control
