基于单片机的数字电容表设计 摘 要 随着工业信息化自动化的发展，数字电容表的优越性日益表现出来。由于它具有功能强、体积小、功耗低、价格便宜、工作可靠、读数方便，精度高等特点，因此特别适用于工业控制或与控制有关的数据处理系统，越来越广发被各个领域和项目采用。它的结构和特点决定了他的强大用途，使得它在智能仪表、仪器、小型检测及控制系统、家用电器中大展身手，倍受青睐。因此掌握好精密型数字 电容表制作的一般设计方法，对于工程设计和开发有十分重要的指导意义。 数字电容表结构更小，更美观，更实用，用户不需要扩充资源就可以更方便的使用，不仅是开发简单，产品小巧美观，同时系统也更加稳定，对数字电容表的研究，通过将科学技术应用到工业生产，从而使得人们真正体会到科技的发展给自己的现实生活所带来的方便和舒适。 本文设计的基于单片机的数字电容表，其主要构成采用的是单片机和LED数码管。它具有功能强、体积小、功耗低、价格便宜、工作可靠、读数方便，精度高等特点，因此特别适用于工业控制或与控制有关的数据处理系统。集成芯片比分立元器件控制电路具有更简单，更可靠的特点和易于调试的优点，可以提高电容表工作的可靠性和性能指标。 关键词：单片机，数字电容表 Abstract Along with the development of industrial information-based automation, the superiority of the number electric capacity form expresses day by day.Because it has function strong, small physical volume, achievement consume low, price cheapness, work credibility, read number convenience, accuracy Gao Dengs characteristics, therefore specially be applicable to industry control or control- related data processing system, more and more and widely deliver quilt each realm and item adoption.Its structure and characteristics come to a decision his strong use and make it is in the intelligence gauge, instrument, small scaled examination and control system, home appliances big exhibition artistic skill, doubly be subjected to favor.The general design method that consequently controls a very precise type the number electric capacity form creation has very important instruction meaning to the engineering design and the development. The number electric capacity form structure is smaller, more beautiful, more practical, its enough that the customer doesnt need to enlarge a resources more convenient use, not only is that the development is simple, the product is cleverly made beautiful, at the same time system also more stable, the research of the logarithms word electric capacity form, pass to apply to science technique industry production, make thus people truely realize the development of science and technol
