摘要
随着科学技术的不断发展,液晶的应用越来越广泛,在电力行业中,带液晶显示的智能仪表也越来越受到用户的青睐。因此,本文设计了液晶显示的电力智能仪表方案。方案采用瑞萨PD78F0485单片机为核心,利用其集成的液晶控制器来实现液晶显示。并采用ATT7026电能计量芯片,通过PD78F0485读取ATT7026中的电量数据来实现电量测量和电能计量。经实践表明,这种方案不仅满足电力智能仪表的测量显示功能,并降低了开发难度和生产成本。可以满足相关行业的需求。
With the continuous development of science and technology, liquid crystal is applied more and mode widely, and in the power sector, the smart meters with liquid crystal display are becoming more and more popular among users. Thus, in this paper, a power smart meter scheme with liquid crystal display is designed. This scheme takes Raissa PD78F0485 single chip micyoco （SCM） as its core, and realizes liquid crystal display via liquid crystal controller integrated by it. Besides, it also adopts ATT7026 electric energy measurement chip, and realizes electric quantity measurement and electric energy calculation as PD78F0485 reads electric quantity data in ATT7026. As it is proven in practice that this scheme can not only satisfy the measurement display function of power smart meter, and also reduce development difficulty and production cost. Therefore, it can satisfy demands of relevant industries.
