【Abstract】 An advanced and reliable world time clock system controlled by microcomputer was discussed and the PL/M programming language-an advanced language which was used to develop single chip microcomputer was used. The feature of this system is that the conversion of parallel data and serial data was realized by using cleverly alternating current power, and that the reliability of this system was improved greatly. In addition, the developing of this system was quickend by using PL/M programming language.更多还原
