 摘 要 20世纪末随着信息科学的发展，信息已经深入地渗透到人们的生活中，人们已经越来越离不开电路板所成的各种电子产品，并已经适应它们所带来的方便。电路板使电路迷你化、直观化，对于固定电路的批量生产和优化用电器布局起重要作用。 Abstract With the development of information science in the end of 20th century, information has deep penetration to peoples lives, people have more and more cannot leave to various kinds of electronic products forming by the circuit board , and they have had to adapt to the convenience. Circuit get minimum and direct by the circuit boards, it in for fixed circuit batch production and optimization with electric equipment layout. The function of the circuit board is strong, use value higher characteristic gradually become the new topic which people pay attention to. Circuit boards texture is the important circuit to control the product electronic . however， it is hard to avoid the quality problems in the production process, for example, circuit’s cables hybrid junction, disconnect, having serious influence of electronic product function. These electronic products not only wont bring convenient to our daily life，it will also increase many unnecessary trouble，this means that you must have a kind of effective tools to detect circuit board，mix line detector is such a tools that can detect circuit boards connected situation，the prototype is the needle bed which used in the production of circuit board . The contents of this paper is mixed line detection based on SCM ，that is based on the theory of 51 SCM knowledge, makes the corresponding design scheme, uses software of keil to program, cascade operates by simulate software of Proteus. The simulation results as expected. That is when the circuit board have the hybrid junction, or disconnect abnormal, alarm circuit alarms. If the connection is correct, the corresponding indicator lights normally. It expounds the working principles of the mixed line and the method to realize. Keywords: Circuit Board, 51 Simple Chip Microcontroller, Mixture Line Detecter, Needle Bed.  目 录 1 绪 论 1 2 MCS-51系列单片机简介 3 2.1 80
