基于CS5460单相电度表的测量的设计 摘 要 随着城农网改造的逐步深入，各种各样的计量工具不断出现在市场上。各种不同的计量工具所使用的计量方法也不一样。该系统由前端电路调理模块，电能表芯片CS5460模块，单片机STC89C52模块，显示模块，存储模块等组成。CS5460实现功率测量和用STC89C52单片机实现电能计量的方法是当下比较成熟的计算方法。CS5460是一种带有串行接口的单向双向功率电能集成电路芯片，用它可以方便的组成多功能电子式电度表和分布式电能计量管理系统。其中使用CS5460芯片设计的简单单相电度表可以用于工业现场的电量数据采集和简单的功率计算，使用CS5460芯片设计的数字电表适用于住宅用电计量的最精确，并具成本效益的电表方案，打开了电表设计的新领域，是下一代民用电表的理想产品和最好的工业解决方案。目前我国高校学生公寓普遍采用限电措施来控制学校电能利用,公寓管理社会化后,限制学生用电将改为鼓励学生安全用电,从而将采用限制安全功率、限制基本电费、超量收费的形式。 关键词：CS5460芯片;STC89C52单片机；液晶显示模块；C51程序 CS5460 single-phase meter based on the design of the measurement Abstract With the gradual deepening of rural power grids city, a variety of measurement tools continue to emerge on the market. A variety of different measurement tools are not the same measurement method used. The system consists of front-end circuit conditioning module, CS5460 chip energy meter module, microcontroller STC89C52 modules, display modules, memory modules and other components. CS5460 power measurement and the realization of single chip with STC89C52 energy measurement method is to present a more mature method. CS5460 is a single bi-directional serial interface with power power integrated circuit chip, it can be easily formed with multi-function electronic power meter and distributed energy metering management system. CS5460 chip design which uses a simple single-phase watt-hour meter can be used to power industrial field data collection and simple power calculation, using the CS5460 digital chip design for residential electricity meter measures the most accurate and cost-effective meter Program, designed to open new areas of the meter, the meter is ideal for the next generation of civilian products and the best industrial solutions. At present, China University Student Apartment commonly used power rationing measures to control energy use of schools, apartment management outsourcing, the restrictions on students use of electricity will be changed to encourage students to safe use of electricity, which will use
