基于嵌入式微处理器的“基表集抄器”的设计与实现

A Design and Development of The “Information Collector of Base Meter” Based on an Embedded Microprocessor

介绍了嵌入式系统的特点,提出了嵌入式系统开发的原则,特别是选择软件平台和硬件平台时需要考虑操作系统的硬件支持、开发工具的支持程度、应用的领域、用户的需求、成本、开发的难易程度等因素.阐述了基于嵌入式微处理器的“基表集抄器”的主要功能是实现各类基表(如电表、水表、气表等)数据的远程采集及通信管理的设备,工作方式采用主/从工作模式,设计了“基表集抄器”的硬件系统,并给出了硬件系统结构的逻辑图;描述了系统软件的设计思想以及系统启动和系统工作流程,同时简述了如何将数据通过以太网络上传至上位机的过程.

In this article, the author describes the characters of an embedded system and put sforward the principle of the system development as well as some factors under consideration when the software and hardware platform are taken, such as the supportability of a hardware platform for the operation system, the supportability of development tools, the application area, the need of customer, the cost and the difficulties of development. The author argues that the major function of an Information Collector of Base Meter （ICBM） based on an embedded microprocessor is to carry out the remote data collection and the communication management for various Base Maters （ Power Meter, Water Meter, Gas Meter, etc. ） by Client/Server mode. The author also designs a hardware system of the ICBM and provides the logical chart of its structure, the method of its software design and its schematic flow-charts of starting-up and running procedure, meanwhile the author introduces the procedure of data transmission up to a host via Ethernet in a few words.
