基与单片机便携式电子秤的讨论摘 要在智能化测量仪表中, 测力与称重控制器工矿企业、 交通运输、 商业贸易和科学技术等各个领域, 甚至每个家庭, 对电子秤的要求越来越高的应用极为普遍, 而电子秤是该讨论领域的重要分支。随着国民经济的进展和人民生活水平的提高, 但由于称重控制器成本及功能的限制, 一直制约了电子秤在各种领域的进一步普及应用。因此, 产品的更新换代是生产进展的要求, 是社会进展的必定。近年来, 新型单片机的出现和传感技术的进展, 为更新产品设计、 研制高性能价格比称重控制器提供了条件。我们采纳M68HC05单片机, 开发了在特别场合使用的专用电子秤的称重控制器。讨论工作使称重控制器集多种功能于一体, 对各种有特别使用要求的电子秤作探究性讨论。本文从电子秤的基本组成入手, 对实现各种专门电子秤功能的软, 硬件分别进行了剖析, 最后还提出了一些改进设想。关键词: 串行通讯 ,电子称, 压力传感器AbstractForce-meter&weighting controllers are widely applied to the intelligent gauges. The research on digital weighting instrument is one of the important branches developed in that field. With the develop- ment of the economy and increment of people's life standard, the digital weighting instrument is subjet- ed to higher criteria, which has been used in industry communication, commercial trade and scientific resear- ch even the household. But the further application of the digital weighting instrument has been constrai- ned from the costs and functions of the weighting controllers. It is in great need for the innova- tion in the product design with respect to the development of the productive force and the society. In recent years, with the appearance of very large scale IC and microprocessor and the improvement of techniques on weighting sensors, it is possible for the development of new type weighting controllers with high quality-cost ratio. We use the M68HC05 micro-controller of to develop the weighting contr- ller applied in...
