随着科学技术的进步和经济的发展,单片机被越来越广泛的应用在我们的生产和生活中。单片机一直以自己的优势来吸引人们的关注,一些以单片机为核心的微型系统在社会的各个领域都正起着积极的作用。目前人们更加关注单片机用电故障控制系统的研究,如何设计出安全的用电系统是科研人员的首要任务。 With the progress of science and technology and economic development, SCM is more and more widely used in our production and life. Microcontroller has always been to their own advantages to attract people’s attention, some of the micro-chip system as the core in all areas of society are playing a positive role. At present, people pay more attention to SCM electricity failure control system, how to design a safe electricity system is the primary task of researchers.
