摘　　要：近几年来,单片机已经被认为在现代文明和技术发展与进步中,起着越来越重要的作用;工业上,单片机技术有着广泛的应用,针对其应用的越来越广泛,提出了利用面向对象技术设计的方法,并将其用于以intel16位系列单片机8098为中央处理单元的电子软设计中;因为三相交流异步电动机启动电流过大,易烧毁或损坏电机,基于单片机系统、集成芯片和可控硅为辅助,提出了三相晶闸管交流调压的数字移相控制方法,通过控制触发角来控制输出电压,从而降低电动机的启动电流,使安全稳定的启动。这种方法具有其特点.即达到了延长异步电动机使用寿命的目的,具有故障显示及自诊断功能。In recent years , single -chips have assumed an increasingly important role in the development and advancement of modern civilization and technology. Single - chips have been found in numerous applications, In view of its application becomes more and more prevalent. It presents the way to apply object - oriented（OO） a- nalysis and design to microprocessor control systems, and apply it to the electronic design with inter 16 （8098）. Because the problems of excessive starting of A. C. Motor , easy damaging due to starting up and protection of motors , an advanced single - chip computer 8098 is used as a main controller, and other integrated chip and thyristor are used asauxilliary ones . A novel digital phase - control strategy based on three - ohase thy.
